The technical result of the proposed method lies in the far detection, accurate classification and precise definition of PR is the spatial coordinate acoustically unobtrusive" BPO in conditions of high ambient noise of technogenic and natural character, as well as intense reverb in the far distance; in hydroacoustic displacement of the BSR, as well as the decommissioning of control systems subsea media BPO; mechanical protection of the frontier against the penetration of surface and submarine carriers BPO; in a multi-stage (two or more steps) cleaning water from MNR and BPR, including from bioprostheses; multistage cooling water used for technological purposes, a relatively simple manner with minimum time and cost savings, compliance with medical safety for personnel and environmental safety for the environment.

There is a method of ensuring the safe operation of hydraulic structures (in particular, systems of water intake NPP), which consists in placing on one side of the controlled foreign unit parametric vysokonapornogo (units of degrees) of the broadband radiation (2-3 octaves) hydroacoustic signals (SGAS), and on the opposite side of the turn block parametric receive reflected from the BPO SGAS (secondary acoustic field) and own souvislosti BPO (primary acoustic field), and subsequent detection, recognition and the determination of the coordinates of the BSR, with the help of low-frequency wave difference frequency (NCWRC), formed in the block parametricexerciseadapter.o radiation SGAS advanced affect the BSR (in particular, their air cavity), causing a sharp negative change in the functioning of internal organs BPO and carrying out their sonar displacement of the controlled water: in the formation of reinforcements, continuous and directed along the protective mechanical screens (SMR) OIE, the radiation in the water intensive with the amplitude of the sound pressure of 5×104PA and higher, acoustic waves of ultrasonic range (USD) frequencies above 20 kHz, the physical destruction or immobilization of bioprostheses (Zebra mussel and so on)in the water, and release of biological impurities (BPR): jellyfish, etc. and bioprostheses from SMR nonlinear acoustic effects: controlled acoustic cavitation, radiation pressure and acoustic flow [Bakharev S.A.

The disadvantages of this method are:

1. The small volume controlled underwater space due to the use of one turn of the observation.

2. Lack of effectiveness of physical protection because of the possibility of the passage of RPU controlled foreign companies (for example, a submersible).

3. The low efficiency of the of detection (for example, range and so on) and recognition acoustically unobtrusive (low noise and with low reflectivity) the BSR.

4. Low efficiency of protection of bioprostheses, due to the implementation of only one boundary in the immediate vicinity of the SBB.

5. The lack of efficiency of protection of the OIE from catching juveniles (body length of 12 mm and larger fish.

6. The inability of water purification from the MPR and BPR.

7. The inability of the cooling circulating industrial water and other

There is a method of ensuring the safe operation of hydraulic structures (in particular, systems of water intake MNGP) in the creation of several - at least three controlled boundaries of the respective blocks parametric vysokonapornogo radiation and reception of SGAS and subsequent detection, recognition and definition of coordinates IN the BSR, manned or unmanned underwater vehicle, in which: each of the active and passive hydroacoustic equipment (GUS) using, respectively, the linear blocks radiation and reception of audio signals (ZV) and ultrasonic (ultrasonic) frequencies, and each gas is placed both on the bottom and the water column; in addition, use: disruption of the natural stratification of the environment and radar tools (RLS), by which not only detect the air (for example, the who pilot aircraft) and surface (for example, speed boats) objects, but also electromagnetic inhomogeneities of air on moving ON; as sound diffusers are used not only air bubbles formed in water due to wind waves, but biological sound scattering (BSRS) layers [Bakharev S.A. Method of detection, recognition and displacement underwater objects from offshore oil and gas platforms.- RF patent №2434245, application No. 2010100191 from 11.01.2010,, publ. 20.11.2011, bull. No. 32].

The disadvantages of this method are:

1. Lack of effectiveness of physical protection because of the possibility of the passage of RPU controlled turn.

2. Insufficient efficiency of detection (e.g., range, etc. and recognition acoustically unobtrusive (low noise and with low reflectivity) the BSR.

3. Low efficiency of protection of bioprostheses, due to the implementation of only one boundary in the immediate vicinity of the SBB.

4. The lack of efficiency of protection of the OIE from getting juvenile fish, due to the immaturity of their organs of hearing.

5. The inability of water purification from MNR and BPR.

6. The inability cooling circulating industrial water use in cooling towers and in the channels, but the water-cooler and other

There is a method of providing safety gidrotehnicheskiy the structures (in relation to intake window), consisting in the formation of 30-50 m from the OIE, the acoustic bubble curtains (APL) and the rising air bubbles MNR and BPR on the surface of the water to the OIE, water in the form of dirty foam, as well as the demolition of the MNR and BPR above OIE, downstream of the river. The acoustic veil (AZ) is formed by the directed upwards and towards the moving stream of water, less intense radiation - amplitude acoustic pressure 103PA and higher, waves ZV frequencies from 20 Hz to 20 kHz, in formation, continuous and directed - toward-down-and-meet-up water flow, intense radiation - amplitude acoustic pressure 5×104PA and above, signals of the ultrasonic frequency, the formation of a controlled acoustic cavitation and the physical destruction of the main part of BPR, as well as the hydroacoustic down to the bottom and hydroacoustic to rise to the water surface MPR and BPR with their subsequent demolition of the flow of water past the OIE [Bakharev S.A. Method of purification of water from algae and suspended solids. - RF patent №2381181 on application No. 2008127474 from 09.07.2008,, publ. 10.02.2010, bull. 4].

The disadvantages of this method are:

1. Insufficient efficiency of water purification, due to the implementation of only two ranges - small (few tens of meters) distance and in the immediate vicinity of the OIE.

2. Lack of effectiveness due to nebo is the possibility to clear from BPR water and protect from subsequent biofouling remote inland from the water intake underwater structures (chambers and others) and equipment.

3. The lack of effectiveness of protection, due to the inability to advance better to clean the water from the MNR and BPR.

A device that implements a method of security (industrial and environmental) operation of hydraulic structures, operates as follows (figure 1-figure 3).

In the process of oke (1), for example nuclear power plants, need to cool the turbine and other equipment. To do this, use a circulating process water, constantly circulating in the interests of its cooling through the cooling reservoir (4) natural (e.g. natural lake) or artificial (e.g., reservoir) origin with the first (longitudinal) separation dam (5), providing a more complete exchange of water in the lake-the cooler (4). However, in certain seasons of the year (e.g. summer) is not provided the desired level (for example, up to 30° C) cooling the circulating process water, which reduces the efficiency of heat extraction from the turbines and other equipment oke (1). The result is reduced industrial safety of its operation. This profound negative changes in the ecosystem of the reservoir-cooler (4): die or lose the ability to reproduce fish, rapidly multiply algae (including bioapatite), etc. that the reduction of the fish population and the increase in the number of benthic) causes Eisenia volume (overgrowth) of the reservoir-cooler (4) and reduction of the environmental safety of operation of the OEC (1), and boonratana underwater structures (e.g., OIE, etc) and equipment (e.g. pumps and so on) due to the reduction of their filtering abilities will cause a fall in industrial security manual oke (1).

In addition, in certain seasons of the year (e.g. spring) water is contaminated down trees (poplar and so on) and shrubs (Thistle etc), which forms the (fluff) in water solid biomass from BPR (15) with zero buoyancy and scores a protective metal grille OIE (17). This reduces their filtration capacity by analogy with boonratana, reduced industrial security manual oke.

In addition, in certain seasons of the year: in spring and autumn periods (intense wind-driven waves and so on) and in summer (dredging, etc.) water in the lake is cooler (4), contaminated MNR (16): particles of clay, etc. that can cause (for example, when the concentration of the MNR in the water more than 40 mg/l) automatic stop of the pump and, consequently, reduces industrial security manual oke (1).

In addition, because of natural instincts (especially during periods of feeding and spawning) adult fish (12) seek to enter into the drainage channels (active mix, and in summer with hot water) and die (or lose the ability to reproduce), and will remoteroot the local population to commercial fishing in drainage channels (2), what complicates the opposition terrorists, legendiruetsya under fishermen; because of the pressure to the OIE (17) currents in power channels (8) juveniles (body length of 12 mm and above), fish (14), without well-developed internal organs (including hearing) in a large number of hits in the SBB (17) and dies, which upsets the balance in the aquatic ecosystem and reduces the environmental safety of operation of the OEC (1).

In addition, the OEC (1) and nuclear power plants, in particular, is currently a target for terrorists, capable of self - DD (11), including individual means of underwater movement, or on the surface media (9): on boats and motor boats (salegenuine for promenade and fishing), or underwater vehicles (10): ASO, etc. or by using SDWG (12), for example, freshwater dolphins, etc. to deliver the necessary quantity of explosives for sabotage and to perform a terrorist act. When this flow turbulization of water, especially in power (8) and drainage (2) channels, the presence of large amounts of plankton and benthos (including due to overheating of the lake is cooler), and fish (because of the desire to fight bioapatites and algae) significantly (on the order and above) increases the nonlinearity of the water environment and makes inefficient use of traditional (linear) the asset is s acoustical means (GUS) for the early detection of underwater saboteurs and their means of delivery (ASO and so on).

Therefore, to ensure the required modern conditions the degree of industrial and environmental safety operation of hydraulic structures legally alienated part (for example, up to 500 m from the SBB) of the reservoir-cooler (4), in the first place, directly adjacent to the power channels (8), build the second (transverse) dividing dam (6), form (e.g., length 300 m) power channel (7), which is also part of the reservoir-cooler (4) and at the entrance to the common power channel (7) expand the first COAGS (28).

Using sequentially electrically connected: the first generator (51) RF signal of the pump, the first MIND (52) and the first RF emitter (53) subsystem (33) passive detection of RPU and their means of delivery, submitted to a few tens of meters from the most narrow place and at the outer side of the first line of security, are forming, strengthening and directed towards the reservoir - cooler (4) the RF of the pump signal at frequency f1close to the resonant frequency f0scatterers of sound (e.g., air bubbles), which are dominant in this water area. Simultaneously, using sequentially electrically connected to the first RF receiver (54), a first amplifier (55), a first detector (56) and the first filter (57) the lower the frequency exercise vysokonapolnennyh (units of degrees) receiving RF waves Raman frequencies: f 1±Ω22- primary acoustic field of BPO and their means of delivery) andf1±Ω'1(Ω'1- secondary acoustic field of BPO and their means of delivery), amplification, detection - allocation of low-frequency signals at frequencies Q2andΩ'1of the RF signals of the Raman frequency f1±Ω2andf1±Ω'1and remove RF interference, respectively. In the exercise in advance (at distances of hundreds of meters-units km) discovery bio: DD (11) and SDWG (12), and early (at distances of a few tens of km) the discovery of their means of delivery: emergent media (9) boats, etc. and underwater vehicles (10) - ASO etc.

Simultaneously, by means functionally connected: the second generator (58) RF of the pump signal at frequency f2the third generator (59) RF of the pump signal at frequency f3the first two-channel RF MIND (60) and the first RF emitter (61) n is pitching subsystem (34) active discovery bio and their means of delivery, submitted to several tens of meters from the most narrow place and at the outer side of the first turn, carry out the formation, strengthening directed to the side of the reservoir-cooler (4) radiation HF pump waves with close frequencies f2and f3close, in turn, to the resonant frequency f0scatterers of sound (e.g., air bubbles), which are dominant in this water area. In heterogeneous aquatic environment perform nonlinear interaction of HF pump waves with the formation of waves sum and difference frequencies. The original HF pump wave: f2and f3and RF wave Raman frequency f2+f3due to significant absorption in the aquatic environment, relatively quickly (a few tens of meters) damped in space, while LF TCG Ω1=f3-f2applies to large (tens of km) distances. This bass TCG Q1close in frequency to the resonant frequency Ω0air cavities DD (11) and SDWG (12): lung, stomach, etc. In the future using LF TCG Ω1sequentially scan (scan) the entire sector for underwater monitoring and LF echo signalΩ'1(in the secondary acoustic field) advance (n is the distance units-tens of km) discover the BSR and their means of delivery: emergent media (9) and underwater vehicles (10).

Using functionally United identical to each other anchors (62), several identical anchor chains (63) and several identical steel placesthe (64)connected between a first steel cables (65), on the surface and throughout the water column, subsystem (35) carried out the first mechanical protection, primarily from the passage of shipping bio: emergent media (9) and underwater vehicles (10), the first COAGS (28). This action prevents unauthorized passage (or breakthrough) via COAGS (28). Simultaneously, by means of a flexible (elastic) solid shield (66) with increased depth work surface, exhibited at the turn at a sharp angle, are delayed and fee (one side of the border - for convenience) by rolls (67), the second steel rope (68) with uniformly distributed along its length and continuously moving along its length mechanical scrapers (69), an object floating and emergent, with air bubbles first VOD MNR (16) and BPR (15). In the do the cleaning water from debris, floating and emerged on the surface of various impurities.

While using consistently functionally connected: the first compressor (71), the first continuous duct (72), the first receiver (73) and several perforated (with a big punch is a resolution - for dropping to the bottom of the BSR and fishes, mixing of bottom water layers from the top, raising the MPR and BPR on the surface; with small perforations for dropping to the bottom of the BSR and fish, as well as to retain the MPR and BPR on the surface) of the duct (74) of the first block (70) subsystem (36) of the first physical protection of the first COAGS (28) are forming the first VOD. The result is still penetrated to the first turn of the bio: DD (11) and SDWG (12) schooling fish: (13) and (14), as well as underwater vehicles (10), sharply due to significantly changed the density of the medium "water-to-air, fall to the bottom and can't move forward in the water column. This schooling fish (13) and (14) due to the linear dimensions of their bodies, turn around and leave this water area, and underwater vehicle (10), DD (11) and SDWG (12) remain at the bottom, and then up the staff security unit of the OEC (1) on the surface of the water.

While using sequentially electrically connected: the first multi-channel generator (76) SGAS, the first multichannel MIND (77) SGAS and identical to each other of the first directional sonar emitters (78) SGAS the first block (75) are forming, strengthening directed towards the BSR and the current, radiation SGAS with the amplitude of acoustic pressure from 103PA and higher at a distance of 1 m from the transducer at a frequency f 4and produce energy far hydroacoustic impacts on bio and fish, as well as carry out acoustic suppression system control underwater vehicle (10). In the main (>50%) number of DD (11) and SDWG (12), as well as clusters of adults (12) and juveniles (13) fish turn around and go back into the reservoir-cooler (4), not approaching this milestone. However, smaller (less than 50%) of their number, as well as underwater vehicle (10), still coming to this country.

Therefore, by sequentially electrically connected: the second multi-channel generator (80) SGAS, the second multichannel MIND (81) SGAS and multiple identical second directional sonar emitters (82) SGAS block (79) are forming, strengthening and directed upwards, the radiation SGAS with the amplitude of acoustic pressure from 103PA and higher at frequency f5produce near hydroacoustic energy impact on BPO and fish, near sonar suppression control systems submarine carrier (10)and hydroacoustic hold (acoustic backwater below) raised the first O.S. on the surface of the sea the main mass of the BPR (15) and MNR (16); the third multi-channel generator (84) SGAS, third multichannel MIND (85) SGAS and identical to each drogarati directed sonar emitters (86) SGAS block (83), they carry out the formation, strengthening directed downwards, radiation SGAS with the amplitude of acoustic pressure from 103PA and higher at frequency f6produce near hydroacoustic energy impact on BPO and fish, near sonar suppression control systems submarine carrier (10)and hydroacoustic down to the bottom of the main mass of the BPR (15) and MNR (16).

As a result, virtually all (>75%) PD (11) and SDWG (12), as well as clusters of adults (12) and juveniles (13) fish turn around and go back into the reservoir-cooler (4), not approaching this milestone. However, slight (less than 25%) of their number still comes to this line, and with acoustically derived from the operation of the navigation system of the underwater vehicle (10) is stuck, entangled in the interconnected first steel cables (65) subsystem (35) the first mechanical protection first COAGS (28). However, almost all (>75%) BPR (15) and MNR (16) remain in the water column: not rise with bubbles first O.S.) on the surface in the form of dirty foam and not pressed to the bottom, increasing and condensing, thereby, the layer of bottom sediments.

Therefore, by sequentially electrically connected: the fourth multi-channel generator (87) RF signals SDM and ultrasonic ranges at a frequency f7fourth, megaran the high MIND (88) and multiple identical fourth RF directed, sonar emitters (89) PDM and ultrasound frequency subsystem (37) of the first water purification first COAGS (28) are forming, strengthening directed towards bubbles first O.S. radiation harmonic signals with the amplitude of acoustic pressure from 100PA and higher at frequency f7close to the resonance frequency of the bubbles in the first VOD. Under the influence of acoustic waves at a frequency f7the bubbles first O.S. in surfacing begin to oscillate exclusive type (compressed and decompressed) and actively attach to the elastic surfaces BPR (15) and MNR (16), and, thus, carry out the first acoustic bubble cleaning of the circulating process water from different (BPR and MPR) impurities through their ascent to the water surface in the form of dirty foam.

Simultaneously, using sequentially electrically connected: the fifth multi-channel generator (90) RF signals, the fifth multichannel MIND (91) and multiple identical fifths HF omnidirectional sonar emitters (92) subsystem (38) the first COAGS (28) are forming, strengthening omnidirectional (all directions) radiation harmonic signals with the amplitude of acoustic pressure from 100PA and higher at frequency f8close to the resonance frequencies of the molecules of the net in the s (12,4 kHz) or its higher harmonics (24,8 kHz and so on), and also close to subharmonic, the fundamental natural frequency of thermal vibrations of the molecules of pure water or its higher harmonics.

Under the influence of acoustic waves at a frequency f8pure water molecules begin to rapidly fluctuate, and ultimately: the faster you rid of various impurities, including colloidal particles; faster to give thermal energy in the surrounding space, including more than cold (especially at partial mixing of the water with pop-up bubbles) layers of water in the bottom (cooled cold groundwater) of the reservoir and the air by reducing the near-surface air diffusion layer and increase the heat transfer of the water and, thus, carry out, respectively, the first acoustic cleaning of the circulating process water from different (BPR and MPR) impurities and the first rapid heat removal from it - primarily due to the increase at the molecular level, heat water, and secondarily due to the evaporation of the water from the surface of the reservoir-cooler (4).

Then reverse the process water through the landscape and the first pump (20) oke (1) output common power channel (7), which is also part of the reservoir-cooler (4), simultaneously serves on the inputs are identical (in purpose and principle of operation) each other Vodootvodny the channels (8) are identical with each other the second COAGS (29), similar in purpose first COAGS (28).

While using consistently functionally connected: the second compressor (94), the second continuous duct (95), the second receiver (96) and several perforated ducts (97) the second unit (93) subsystem (39) the second physical protection of the second COAGS (29) are forming the second VOD. As a result, the part still penetrated to the second turn part of the accumulations of fish (13) and (14), sharply fall to the bottom, turn around and leave this water area; using the fourth multi-channel generator (99) SGAS, fourth multichannel MIND (100) SGAS and multiple identical fourth directional sonar emitters (101) SGAS second block (98) are forming, strengthening and directional radiation SGAS with the amplitude of acoustic pressure from 103PA and higher at frequency f9and far energy hydroacoustic impacts on fish. As a result, virtually all (more than 90% of the original quantity) fish turn around and go back, not approaching this milestone. However, slight (less than 10%) of their number still coming to this country. Therefore, by sequentially electrically connected: the fifth multi-channel generator (103) SGAS, fifth multichannel MIND (104) SGAS and several Ident is cnyh each other fifths directed sonar emitters (105) SGAS unit (102) are forming, strengthening and directed upwards, the radiation SGAS with the amplitude of acoustic pressure from 103PA and higher at frequency f10produce near hydroacoustic energy impacts on fish and hydroacoustic hold raised the second O.S. on the surface of the water remaining mass BPR (15) and MNR (16).

However, part of the BPR (15) and MNR (16) remain in the water column: not rise with bubbles the second O.S.) on the surface in the form of dirty foam and not pressed to the bottom, increasing and condensing, thereby, the layer of bottom sediments. Therefore, with the help subsystem (40) of the third water treatment second COAGS (29), similar in composition subsystem (37) of the first water purification first COAGS (28), are forming, strengthening and directed towards the second bubbles O.S. radiation harmonic signals with the amplitude of acoustic pressure from 100PA and higher at a frequency close to the resonance frequency of the bubbles and, thus, provide a second acoustic bubble cleaning of the circulating process water from different (BPR and MPR) impurities through their ascent to the water surface in the form of dirty foam.

Simultaneously, with the help subsystem (41) of the fourth water treatment second COAGS (29), similar in composition subsystem (38) of the second water purification first COAGS (28), are forming, strengthening and nenadi the run (on all sides) radiation harmonic signals with the amplitude of acoustic pressure from 10 0PA and higher at a frequency close to the resonant frequencies of molecules of pure water (12,4 kHz) or its higher harmonics (24,8 kHz and so on), and also close to subharmonic, the fundamental natural frequency of thermal vibrations of the molecules of pure water or its higher harmonics, and thus, carry out, respectively, the second acoustic cleaning of the circulating process water from different (BPR and MPR) impurities and the second fast heat from it.

Then the reverse process water, fully (100%) released from bio: DD (11) and SDWG (12), almost completely (>90%) purified from MNR (16), is almost completely released from Mature fish (13) and juvenile fish (14), almost completely cooled and substantially purified from BPR, but partially aerated (as a result of turbulent mixing and partial saturation bubbles O.S.) thanks to the first (20) and second (24) pumps oke (1) with the output of the respective power channel (8) consistently served in the OIE (17), underwater camera (18) and the water cooler (19).

While using sequentially electrically connected: the first generator-modulator (106) LF signal at frequency Ω3multichannel - not less than 4 channels (number of parties OIE) MIND (107) and identical to each other first emitters (108) are forming, strengthening and radiation LF signal the (envelope) at a frequency close to the resonance frequency of 6.5 Hz living cell. Under the influence of the sonar signal at a frequency close to the resonance frequency of a living cell, the remainder of schooling fish (13) turns away from the OIE (17). As a result, in OIE (17) due to a flowing stream of water hits a tiny (less than 1%) of the original clusters (13) of Mature fish (mainly patients) and small (less than 5%) of the original clusters (14) juvenile fish (mostly sick and tired), and, thus, provide almost complete (>95%) the protection of all fish from getting into the OIE, and death (environmental security), as well as provide almost complete protection (industrial safety) wire (mesh size 4×4 mm) protective metal mesh OIE from clogging the carcasses of fish, mostly juveniles.

Simultaneously, using sequentially electrically connected: the sixth generator (109), the sixth multichannel MIND (ON) and identical to each other sixth RF emitters (111) subsystem (43) fifth water purification, are carried out shaping, amplification and radiation of acoustic signals at a frequency f11under the influence by the physical destruction of bioprostheses in areas of water flow in the vicinity of the emitters (111), as well as full on asdigian of bioprostheses - remote from the emitter (111) areas of water flow, and, thus, provide almost complete (>95%) protection of underwater structures and subsea equipment from fouling (industrial security).

Simultaneously, using sequentially electrically connected: the seventh generator (112), the seventh multichannel MIND (113) and identical to each other seventh RF emitters (114) subsystem (43) fifth water purification, are carried out shaping, amplification and radiation of acoustic signals at a frequency f12under the influence of which provide growth and subsequent collapse of bubbles of air trapped (including dissolved) in water, i.e. implement controlled acoustic cavitation, and thus provide almost complete (>95%) degassing of the water, preventing the occurrence of hydro-cavitation effects on the blades, water pumps, etc. (industrial security).

In the process units oke (1) circulating process water is heated (for example, up to 45°C or more), so thanks to its corresponding second pump oke output corresponding water cooler (19, consistently served in the corresponding first horizontal conduit (21), concrete discharge channel (22), the second horizontal conduit (23), the vertical conduit (25), gra is the IREN (26), sprinkling pool (27), corresponding to the discharge channel (2)drainage channel (3) and in the reservoir-cooler (4).

However, the circulating water is not only heated, but also partially contaminated by MNR and, especially in emergency, petroleum products. Simultaneously, due to the natural instincts of the accumulation of Mature fish (13) tries to log in turbulent flow (e.g., spawning, etc). In addition, the OEC (1), and nuclear power plants, in particular, is currently a target for terrorists, capable of self - DD (11), including individual means of underwater travel, on the surface (9) or underwater (10) carriers, to deliver the necessary quantity of explosives for sabotage and to perform a terrorist act. This turbulization flow of water in drainage channels (2) and (3)the presence of large amounts of plankton and benthos in the reservoir-cooler (4) significantly increases the nonlinearity of the water environment and makes inefficient use of traditional active GUS for the early detection of PD (11), SDWG (12), surface (9) and underwater (10) their means of delivery. Therefore, to ensure the required modern conditions the degree of industrial and environmental safety operation of hydraulic structures at the outlet of the respective discharge channel (2) and on the ode General drainage channel (3) establish, accordingly, the fourth COAGS (31), similar in composition and appointment of the second COAGS (29), and the fifth COAGS (32), similar in composition and appointment of the first COAGS (28).

Thus: using block (93) are forming V.O.. As a result, the part still penetrated to the given boundary part of the schooling fish (13) dramatically fall to the bottom, turn around and leave this water area; using the block (98) are forming, strengthening directional radiation SGAS with the amplitude of acoustic pressure from 103PA and higher energy and far hydroacoustic impacts on fish. As a result, virtually all (more than 90% of the original quantity) fish turn around and go back, not approaching this milestone; using block (102) are forming, strengthening directional bottom-up, radiation SGAS with the amplitude of acoustic pressure from 103PA and higher, and produce near-field acoustic energy impact on fish.

Thus: using the subsystem (33) provide passive detection of RPU and their means of delivery; by the subsystem (34) are actively detect the BSR and their means of delivery; by using subsystem (35) provide mechanical protection for the passage of vehicles bio: emergent media (9) and underwater vehicles (10), fifth COAGS (32); through the th subsystem of (36) are forming O.S.; and with the help of subsystems (37) and (38), purified water. In the same way, but for spillway, provide industrial and environmental safety of hydraulic structures on the opposite (intake) side of the pond. When you do this:

The presence of the distinctive features of the prototype features allows you to make a conclusion on the conformity of the proposed method the criterion of "novelty".

Analysis of the known technical solutions to detect in these distinctive characteristics, showed the following.

Signs: 3, 5, 7, 8, 9 and 11 are new and unknown to their use for security (industrial and environmental) operation of hydraulic structures.

Signs 1, 4, 6, and 10 are new known. At the same time known use: grounds 1 - to improve the efficiency of the cooling water in the water cooler due to the mixing of water masses; 4 and 6 - to protect fish, including juveniles, from getting into OIE; 10 - for the physical protection of drainage channels from falling PD, including individual and collective means of transport.

Sign 2 is known.

Thus, the availability of new features in conjunction with the well-known provides the appearance of the proposed solutions new properties that do not match the properties of the known technical solutions to provide remote detection, accurate classification and accurate determination of spatial coordinates of the acoustic instrument and subtle" BPO in conditions of high ambient noise sea of man-made and natural origin, as well as intense reverb; hydroacoustic the displacement of the BSR, as well as the decommissioning of control systems subsea media BPO; mechanical protection of the frontier against the penetration of surface and submarine carriers BPO; multistage water purification from MNR and BPR, including from bioprostheses; multistage cooling water used for technological purposes, a relatively simple manner with minimum time and cost savings, compliance with medical safety for personnel and environmental safety for the environment.

In this case, we have a new set of features and their new relationship, and not easy integration of new features and is already known in underwater acoustics, namely the operations in the proposed sequence and leads to a new effect.

This fact allows to make a conclusion on the conformity of the developed method the criterion of "substantial differences".

An example implementation of the method.

First, it should be noted that the biological effect of LF acoustic vibrations on the human body purposefully studied by specialists of the research Institute of Industrial and marine medicine" of the Russian Military-medical Academy. In the result of years of research it was found that the frequency of 4 Hz blagopri is but affects the heart, frequency 6...7 Hz have a negative impact on the brain, 13 Hz causes an upset stomach, etc. [douguchi V.V. Tikhonov, M.S.. Kudrin I.D. Biological action of low-intensity environmental factors on the human body. - Ecological systems and devices. No. 1, 2002, pp.37-39].

The work was carried out in the period from 1983 to 2013, including: from 1983 to 1999 - on marine protected the interest of the Navy of the USSR and Russia; from 1999 to 2007 in South Korea, including in the interests of NPP "Kori-1; 208 2010 - Vietnam, including in the interests of the projected NPP; from 2011 to 2013 in Russia: at Kalinin NPP, Krasnoyarsk hydroelectric power station, etc.

Figure 4 illustrates the external appearance of the passive gas with parametric receiving antenna (PAP), capable of installation in stationary and offline versions, in which the radiation pattern in the horizontal plane is rotated by mechanical means. At the same time as receiving elements of the antenna used electroacoustic transducers removed from service in the Russian Navy anti-sabotage GUS MG-7, and the antenna device with stabilizers depth, display device and part of blocks of linear processing of signals from the removed from service in the Russian Navy helicopter GUS MG-329M.

Figure 5 illustrates the appearance of the active gas with parametric radiating antenna PIA), able to install in the stationary system, in which the radiation pattern in the horizontal and vertical plane is rotated by mechanical means. At the same time as receiving elements of the antenna used electroacoustic transducers removed from service in the Russian Navy anti-sabotage GUS MG-7, and the antenna device with stabilizers depth, display device and part of blocks of linear processing of signals from the removed from service in the Russian Navy helicopter GUS MG-329M.

Figure 6 illustrates the appearance of the upgraded speaker system energy impacts on biological underwater objects: DD, SDWG, fish, etc. This speaker system was developed in the Hydro-Center, Vladivostok, under the scientific leadership of Dr. M.N. J.V. Matvienko as applied to sonar measurements and provides the radiation of acoustic signals in the frequency range from 10 Hz to 100 kHz.

7 - Fig presents the results of the use of the developed method security (industrial and environmental) security operation of hydraulic structures.

On Fig.7 and Fig in the form of histograms presents average values of the distances of detection using active gas with PIA (7) and using the pass is active with GUS A (Fig) the following: I - surface media (boat) bio; II - underwater vehicle (Autonomous manned submersible type "TINRO-2") BPO; III - PD fins; IV - SDWG (type sea lion); V - concentrations of fish. This dashed lines selected histograms for the nearest analogue, and solid lines selected histograms for the developed method.

As can be seen from Fig.7 wins in the detection range: emergent media (I) bio; underwater media (II) bio; PD fins (III); SDWG (IV); schooling fish (V) in the active mode of operation designed GUS are, respectively: 1.7 times (4.1 km and 2.4 km); 1.8 (2.5 km and 1.4 km); 1.7 (1.6 km and 0.9 km); 1.9 (1.5 km and 0.8 km) and 2 times (1.4 km and 0.7 km). As can be seen from Fig wins in the detection range: emergent media (I) bio; underwater media (II) bio; PD fins (III); SDWG (IV); schooling fish (V) in the passive mode of operation designed GUS are, respectively: 1.4 (5.2 km and 3.7 km); 1.7 times (3.1 km and 1.8 km); 1.7 (1.4 km and 0.8 km); 1.7 (1.2 km and 0.7 km) and 2.5 times (1.4 km and 0.7 km).

Figure 9 in the form of histograms presents average values of the efficiency of fish protection on the outputs of different security boundaries: I - the entrance to the common power channel; II - entry into the appropriate power channel; III - intake box of the relevant power channel; IV - release of their respective drainage channel; - the output of the common drainage channel. : Dashed lines selected histograms for the nearest analogues, and solid lines selected histograms for the developed method; according to the requirements of SNiP 2.06.07-87 "Retaining walls, shipping gateways, fish passage and fish protection facilities, the effectiveness of fish protection (including fish with a body length of 12 mm and above) should be provided with efficiency not less than 70%.

As can be seen from Fig.9, the gains in efficiency of fish protection at the first, second and third security lines are: 11% (74% and 63%), 19% (92% and 73%) and 17% (97% and 80%). In this case: the effectiveness of fish protection increases from the first line to the third, and the developed method allows to provide the required efficiency of fish protection already on the first turn of the security. As can be seen from Fig.9, currently on IV (the output from the corresponding drainage channel) and V (output of General drainage canal) boundaries generally do not ribosomic. As a result, fish (especially during the spawning period) due to natural instincts (reproduction) comes in a turbulent flow of drainage channels with hot water, loses the ability to reproduce and even killed. The process of fish kills in these channels is exacerbated in the hot summer months (June-August). During the implementation of the developed method the main m the SAR of fish (over 80%) is already on the external (fifth) line. In the result, there is no need for continuous stocking of the reservoir-cooler and, ultimately, significantly reduced environmental costs and energy complex (e.g., NPP). In addition, the absence of fish in the drainage channels does not provoke the Amateur fisherman for fishing in prohibited areas and, ultimately, increases industrial (anti-terrorism) security.

Figure 10 in the form of histograms presents average values of the content of the MNR in water (mg/l) at different security boundaries: I - water-cooler - the entrance to the common power channel; II - the output of the common power channel, III output from the respective power of the channel input to the appropriate OIE; IV - release of their common drainage channel; V - output from the corresponding drainage channel. This dashed lines selected histograms for the nearest analogues, and solid lines selected histograms for the developed method; when the content of the MNR in water at a concentration of 40 mg/l (threshold level) triggers automatic protection and stops the supply of water for cooling equipment.

As can be seen from figure 10, the content of the MNR in the circulating process water at the nearest analogue is: 27 mg/l as input in the total power of the channel and at the entrance to the appropriate OIE, i.e. OST what remains constant; 29 mg/l, as input into the appropriate drainage channel, and output the total drainage channel, i.e. remains constant. While the developed method decreases: 27 mg/l at the entrance to the common power channel up to 14 mg/l at the inlet to the appropriate power channel and up to 4 mg/l at the inlet to the appropriate OIE (the cleaning efficiency will collect the circulating process water 85%); 29 mg/l at the inlet to the appropriate drainage channel, up to 15 mg/l at its output and up to 5 mg/l at the output of the common drainage channel cleaning efficiency discharged into the reservoir the cooler circulating process water was 82.5%). Thus, significantly increase the safety of operation of hydraulic structures in adverse weather conditions (wind-driven waves and so on) or when dredging in the reservoir-cooler.

Figure 11 in the form of histograms presents average values of water content (June-August): living and moving BPR (line of dots); alive but motionless BPR (dotted line) and the dead BPR (solid lines) in water (million units/m) at different security boundaries: I - exit lake-cooler - the entrance to the common power channel (background value); II - the corresponding output power of the channel input in soo is relevant OIE; III - out of the relevant OIE, in the process of implementation of the developed method. As can be seen from 11, in the lake-the cooler the total content of BPR is 66 million units/m3. Of them: 41 million units/m3- living and moving BPR; 23 million units/m3is alive but motionless BPR and 2 million units/m3- dead BPR. While the content of BPR at the output of the corresponding channel power decreased by 27 million units/m3(cleaning efficiency 41%) and amounts to 39 million units/m3, of which 25 million units/m3- living and moving BPR; 13 million units/m3is alive but motionless BPR and 1 million units/m3- dead BPR; from 39 million units/m3BPR output from the relevant OIE: 2 million PCs/m3- alive and moving; 8 million units/m3is alive but motionless BPR and 29 million units/m3- dead.

On Fig in the form of histograms presents average values of temperature (T°C) water in the hottest summer period (July-August) at different security boundaries: I - water-cooler - the entrance to the common power channel; II - the output of the common power channel III - you are the od of the corresponding power channel - the input to the appropriate OIE; IV - release of their common drainage channel; V - output from the corresponding drainage channel. : Dashed lines selected histograms for the nearest analogues, and solid lines selected histograms for the developed method; dash-dotted line denotes the temperature (46°C) circulating process water input into the appropriate drainage channel; when the temperature of the circulating process water at 35°C (environmental threshold level) starts the degradation of protein in all aquatic biological objects; when the temperature of the cooled circulating process water in 40°C (threshold level) stops cooling equipment (e.g. turbines) and triggered automatic protection (e.g. protection of reactor for nuclear power plants).

As can be seen from Fig, in the process of implementation of the developed method the temperature of the circulating process water consistently decreased from 46°C (dash-dotted line) to 23°C (solid histogram index III) cooling efficiency of 50%, while its nearest analogue: from 46°C to 31°C - cooling efficiency of 32% (loss on this private performance indicator 18%).

SUBSTANCE: invention is used to protect underwater structures and equipment from biofouling. The method includes, at the output of a bypass channel, generating and emitting energy, information, high-gradient and bioresonance signals which act on fish and change their behavioural characteristics; simultaneously emitting noise signals and creating a dense air-bubble screen which rises on the surface of biofouling and impurities. The air-bubble screen and the noise acoustic waves are additional barriers for aggregation of fish near the output of the bypass channel with superheated water. A floating boom is turned on the water surface to form a continuous barrier for biofouling and impurities rising to the surface, which are then collected in form of dirty foam. A mobile system equipped with acoustic radiators is used to forcefully move the aggregation of fish - natural predators for biofouling, from a remote part of a water body to a region adjacent to a supply channel by continuously emitting energy, information, high-gradient and bioresonance signals. Simultaneously, a second acoustic module and a second acoustic-bubble module are used to form an acoustic barrier for fish - natural predators of biofouling, as well as an acoustic-bubble shield in the narrowest part of the water body. Recycled water being cooled in the water body is further purified from biofouling and impurities and fish are not released from this part of the water body. Simultaneously, a third acoustic module and a third acoustic-bubble module are used to form an acoustic barrier for juvenile fish- natural predators of biofouling, as well as an acoustic-bubble shield at the input of the supply channel of the facility of the power system. As a result, recycled water cooled in the water body is further purified from biofouling and impurities. Simultaneously, intense ultrasonic waves and low-frequency electromagnetic waves act on the biofouling at the input of a water-intake window, with simultaneous removal of biofouling from the mechanical protective screen, and at the output of the inlet pipe of the underwater structure. Simultaneously, an acoustic filter mounted at the input of the equipment of the facility of the power system performs fine purification of water from biofouling, as well as biological and mechanical impurities.

EFFECT: high quality of purification and reliability of protecting underwater structures and equipment from biofouling.

SUBSTANCE: signal is received by a static fan a beam pattern. Input information received by all beam patterns is discretised. All received readings are stored. Information in the beam patterns is processed successively as input information comes in. A threshold is calculated on the average value of all readings measured in the first reception cycle on all beam patterns. The overshooting of the selected threshold is automatically detected successively on all beam patterns of the of the static fan. The amplitude and number of the reading exceeding the threshold are measured and stored. The number of the beam pattern in which the threshold was exceeded is measured and stored. The maximum amplitude is measured. The successive operations are repeated for the next 3 or more transmissions. The measured maxima are identified on beam patterns and on transmissions. Radial velocity of the object to be classified is measured. Dispersion of the maximum amplitude of the echo signal from the object is calculated for 3 or more transmissions. The object is a surface object if the value of the dispersion of the maximum amplitude is higher than the threshold. The target is an underwater target if there are more than 3 transmissions, the radial velocity of the object to be classified is constant and if conditions are not satisfied.
