The invention relates to hydraulic construction, and in particular to methods and structures designed to pass fish producers through retaining structures for spawning and feeding.

Known way to pass fish fish passage through the tract of the fish-pass [1], which consists in creating a managed water flow along the entire length of fish passage tract, with a managed thread, depending on the difference of the levels of the upper and lower pools and types of noise fish, create in each cell of the fish way as a result of supplying additional water flow in the system truefinish nasdaw placed above and below plavnogo holes located in the transverse wall and aimed at an angle to each other, in the direction of the upstream, the subsequent formation of two rows of submerged hydraulic jets and creating, at the joint between the hydraulic jets, hydraulic sapim favorable conditions for fish passage in the direction of the upstream.

The disadvantage of this method is low efficiency of creating the hydraulic resistance of the stream flowing through vplive hole fish way.

The closest technological scheme and the achieved result is the method of crossing fish fish passage through the tract of the fish-pass [2], which consists in creating a managed water flow along the entire length of fish passage tract, with a managed thread, depending on the difference of the levels of the upper and lower pools and types of noise fish, create in each cell of the fish way, as a result of supplying additional water flow in the system truefinish nasdaw placed above and below plavnogo holes located in the transverse wall and aimed at an angle to each other, in the direction of the upstream, the subsequent formation of two rows of submerged hydraulic jets and the establishment of the joint between the hydraulic jets of hydraulic resistance to flow for fish passage tract and cells of the fish way from the top of the water, thereby creating favorable conditions for fish passage through vplive hole in the side of the upstream.

The disadvantage of this method is low efficiency of creating what I pass fish from downstream of the waterworks at the top [1], including an open top overflow tray with transversely spaced dividing walls, separation walls are made with located in the lower part of the fish passage holes of rectangular shape, the perimeter of which are streamresult nozzle at an angle to the axis of the hole.

The disadvantage of this fish way is the low efficiency passes the fish to the side of the upstream.

The closest in technical essence and the achieved result is a fish-pass [3], including fish passage route connecting the upper and lower pools of the waterworks, made in the form of chambers interconnected by transverse partitions and posted speed or in the form of a chute channel longitudinal slope toward the downstream, bottom vplyvanie the holes drilled in the transverse partitions, and vplyvanie the openings from the side of the upstream executed with trueorigin nozzles communicated with the source of the working environment and placed above and below the longitudinal axis plavnogo holes, while the nozzle is oriented at an acute angle to the longitudinal axis Plavnik holes, moreover, the nozzles are located between the shielding canopies placed around the perimeter Vodytsia formed inside visors output part plavnogo holes and parallel to the plane of the adjacent shielding visor.

The disadvantage of this fish way is the low effectiveness of the creation of the hydraulic resistance of the stream flowing through vplive hole fish way and therefore low efficiency passes the fish to the side of the upstream.

The aim of the invention is the creation of effective hydraulic conditions for fish passage in the tract, providing the necessary hydraulic resistance to the flow flowing through vplive hole fish way, and creating effective conditions for the promotion of fish length fish passage tract.

The invention consists in the following.

Under item 1 of the claims. With the formation of hydraulic jets directly in vpliva hole, maximum possible ejection of additional expenditure from the downstream chamber of the fish way and at the same time are more effective conditions for creating a hydraulic resistance to flow in the output part plavnogo holes.

Under item 2 of the claims. The formation of hydraulic jets in offline channels above and below the longitudinal axis plavnogo holes, allows you to create a hydraulic jet of larger diameter, having a large ejection able is igenii through vplive hole has no direct contact with the valves and high-speed sections of the hydraulic jets.

Under item 3 of the claims. Placing a shielding canopies on transverse bulkhead, side of the upstream, around the perimeter plavnogo holes both above and below truefinish nasdaw allows you to generate the output part of the ejection system. This produces the classical scheme of the ejector, which is characterized by maximum efficiency.

Under item 4 of the claims. Placing a shielding canopies in the horizontal plane does not obscure vplive hole and does not interfere with free passage of fish to the side of the upstream.

Under item 5 of the claims. Placing a shielding canopies at an angle to the longitudinal axis plavnogo holes allows you to create the optimal output form part of the ejection system. Thus the orientation of the axes of the hydraulic jets at an angle to each other allows you to generate the maximum hydraulic resistance before plavnym hole.

Under item 6 of the claims. Submission of additional flow to the system nasdaw on Obvodny pressure pipe communicated with the upper tail of the waterworks, allows efficient use of the kinetic energy of the drop in water levels of the lower and upper dams. This layout is possible for cameras fish way, location) possible effective operation of the system nasdaw and forming them submerged hydraulic jets.

Under item 7 of the claims. The supply of hydraulic jets around the perimeter plavnogo holes allows you to get the maximum hydraulic resistance before plavnym hole.

Under item 8 of the claims. Submission of pre-twisted hydraulic jets allows you to use their dynamic and geometric characteristics, namely a larger diameter distribution and energy swirling jet. It is known that swirling jets have a larger diameter at their distribution in the stream, but the range of their distribution in the flow is less than in the case of non swirling jets. The swirling flow has a transverse velocity component of flow and its interaction with the stream coming from the camera, fish-pass, results in greater hydraulic resistance generated before plavnym hole.

Under item 9 and 10 claims. Scheme tightening hydraulic jets clockwise or counterclockwise is a variant of submission of swirling jets in the stream.

Under item 11 of the claims. Scheme pairwise spin neighboring hydraulic jets in direction to each other allows you to use the effect of vsemogushaya these jets when vzaimodeystviya.

Under item 12 of the claims. This scheme twist creates a greater hydraulic resistance, it also uses the effect of vsemogushaya jets, twisted in different directions.

Under item 13 of the claims. The placement of the outlet openings nasdaw directly in vpliva the opening between the vertical planes of the side surfaces of the transverse partitions allows you to create maximum hydraulic resistance to the flow coming from the camera fish way.

Accommodation dealer collectors within the cross partitions allows you to remove excess harmful interference with fish moving along the cameras tract of fish passage, in the direction of the upstream. On the other hand, this layout is compact and is responsible for the effective operation of the system nasdaw.

The layout of the chamber of the fish-pass, located on the bottom of the water, together with pressure bypass pipe connecting system nasdaw with the upper tail, allows for efficient use of the kinetic energy of the drop in water levels of the upper and lower pools and simultaneously to reduce the consumption of energy previously spent on the operation of the pumps.

Under item 14 of the claims. Execution plavnogo holes with stronyeniye nasdaw directly in vpliva the hole to improve the ejection of additional flow from the lower chamber and the upper chamber (Fig.1).

Under item 15 of the claims. Running through holes in the transverse wall above and below plavnogo hole and coaxially placing them in truefinish nasdaw allows you to create offline channels that optimize ejection system, increasing its efficiency. On the other hand, wholly exempt vplive opening for free passage of fish and nozzles do not interfere and do not injure the fish.

Under item 16 of the claims. Execution of inlet and offline channels with protective grille helps prevent the fish from getting inside the channels.

Under item 17 of the claims. Execution Plavnik holes square shape allows you to create multiple bottom opening that extends the range of tracks the movement of fish, moving in the direction of the upstream. In addition, this geometric form is more compact and using it you can get a greater hydraulic resistance created by the stream flowing through the chambers of the fish-pass. Indeed, the jets exactly the same around the perimeter plavnogo holes and, accordingly, the efficiency created, managed, flow will be higher than in the case of the prototype.

Under item 18 of the claims. Execution Plavnik the us chamber of the fish way.

Under item 19 of the claims. Execution Plavnik holes round shape allows you to get the same effect as in the case of p. 17, but in this case, the inversion of a round jet and its shape allow for a more uniform velocity field over the entire area plavnogo holes.

Under item 20 of the claims. Execution Plavnik holes tiered, with offset holes of the upper tier in relation to the holes of the lower tier, allows you to generate vplyvanie holes for demersal fish species, and fish that live near the surface of the stream.

Under item 21 of the claims. Supply end sections of the inlet pipeline twisting device allows to increase the efficiency of the ejection system. Swirling jet has a larger diameter at their distribution in the stream, but a smaller range, as some of the kinetic energy of the flow required for its interaction with the surrounding flow, as it is with their distribution creates more resistance, which largely creates transverse component of the velocity vector.

On p. 22 and 23 of the claims. Perform cutting torquing fixture as clockwise and against Carnoy twist neighboring hydraulic jets in direction to each other allows you to use the effect of vsemogushaya these jets when interacting with each other. The value of the total hydraulic resistance generated by all nozzles will increase.

Under item 25 of the claims. Perform cutting torquing devices nasdaw placed above the longitudinal axis plavnogo holes, cuts, allowing you to tighten the hydraulic jet counterclockwise, and performing cutting torquing devices nasdaw below the longitudinal axis plavnogo holes, allowing you to tighten the hydraulic jet clockwise allows you to get such a scheme of spin, which creates a greater hydraulic resistance, it also uses the effect of vsemogushaya jets, twisted in different directions. A similar effect is observed when the direction of spin of the jets is changed to the opposite, i.e. above plavnogo hole jet spin clockwise, and the jet below plavnogo hole spin counterclockwise.

How to skip a fish of fish passage through the tract is as follows.

Of the top 3 water serves the water flow, ensuring the creation of attracting fish flow and normal conditions for the promotion of fish of fish passage along the path 1. Simultaneously create a managed thread formed before the weekend is Asadov 8, installed either directly in vpliva hole 7 (Fig.1), or placed in offline channels 12 (Fig.3). With the formation of hydraulic jets before plavnymi holes 7, from the side of the upstream generated hydraulic resistance (Fig.25), significantly reducing bandwidth Plavnik holes 7 through the plot of back pressure. When this hydraulic jet actively ejection part of the fluid volume of the downstream chamber 5 and submit it to the upstream chamber 5. Option integrated power truefinish nasdaw 8, placed in Plavnik the holes 7 of the transverse partitions 6 connecting the camera 5 fish way, located in the head, the input part. In this case, from the top 3 of the downstream pressure through the bypass pipe 11 serves the flow of water, which is distributed to the nozzles 8 (Fig.8). When this upper chamber 5 of the fish-pass, where the magnitude of the difference in water levels is not possible to create a predetermined pressure in the system truefinish nasdaw 8, receive additional water flow from the pump 17, which is also distributed system nasdaw 8.

A possible implementation of the method in the formation of hydraulic jets in avtonomna is. is this case, the arrangement of the jets as close as possible to the classical form of the ejector, which significantly increases the efficiency of the entire system nasdaw 8, and at the same time vplive hole 7 is released by valve that dramatically reduces the number of fish in its upward tract of fish passage 1. In addition, in this embodiment of the composition to achieve the formation of jets of larger diameter, having a large ejection capability.

Installation of shielding canopies 9 around the perimeter Plavnik holes 7 from the side of the upstream allows you to generate the output part 10 ejection system, and the nozzles 8 are located inside and is oriented parallel to the planes of screening visors 9. However visors 9 may be located in a horizontal plane or at an acute angle to the longitudinal axis Plavnik holes 7 (Fig.14 and 15).

The method can be implemented also in the case when part of the lower chambers 5 fish way fed through the bypass discharge pipe 11 connecting the upstream face and systems truefinish nasdaw 8. In this case, effectively uses the kinetic energy of the drop in water levels at hydroelectric 4.

The implementation of the method in the case of supply side hydraulic the operating system.

Creating a managed thread before plavnym hole 7 are possible in case of submission of pre-twisted hydraulic jets, who with their distribution create additional hydraulic resistance (Fig.16). This creates a hydraulic jet with a larger diameter, which in the interaction with the incident flow form the additional hydraulic resistance.

As options various schemes twist jets - clockwise (Fig.17) or counterclockwise (Fig.18).

The implementation of the method is possible when submitting pre-twisted pairs of hydraulic jets in direction to each other, which increases created by the hydraulic resistance due to the effect of vsemogushaya the kinetic energy of the neighboring hydraulic jets.

Scheme twist in a clockwise direction hydraulic jets located above the longitudinal axis plavnogo holes 7, and simultaneously twist hydraulic jets, located below the longitudinal axis plavnogo holes 7 in the counterclockwise direction (Fig.20) also uses the above-described effect vsemogushaya.

The use of twisted hydraulic jets to create the managed water flow p is effective fish way and effective fish passage for fish passage path 1 in the direction of the top 3 downstream.

Fish-pass works as follows.

Of the top 3 water serves the design water flow rate, which is passed on fish passage route 1, passing through vplyvanie holes 7. At the same time the work includes system truefinish nasdaw 8, located directly in Plavnik holes 7 (Fig.1) or offline channels 12, they form a hydraulic jets that create hydraulic resistance before plavnymi holes 7, improving fish passage downstream from chambers 5 in the upstream chamber 5 fish way. The formation of hydraulic resistance greatly assist in the screening visors 9 placed around the perimeter Plavnik holes 7 from the side of the headrace channel and secured to the transverse partitions 6. However visors 9 form the output part 10 plavnogo holes 7 and the output section of the ejection system. There are two options for powering systems nasdaw 8: the first circuit operate the pump 17 (Fig.24), the second scheme combined upper chamber 5 is fed from a pump 17, and the lower chamber 5 from the bottom 2 powered downstream bypass pressure pipe 11 provided with the top 3 and downstream systems truefinish nasdaw 8 (Fig.8). General view of rybarski 7 is an option presented on Fig.3. Layout Plavnik holes 7 may be different (Fig.4, 5, 6, 10, 11 and 12), each option has its pros and cons, but the designers, depending on the installation of ichthyologists, there is a wide choice for the final decision.

An unquestionable advantage of the technical solutions of the fish way is the application of torquing devices 15 mounted inside the end parts of the discharge pipe 11 (Fig.16) that allows you to pre-tighten the hydraulic jet around its axis and then flooded to form a hydraulic jet, creating a hydraulic resistance to the flow. Schema twist jets (Fig.17, 18, 19, 20, 21, 22 and 23) may be different, but each of them contributes to the formation of the maximum hydraulic resistance before plavnymi holes 7 (Fig.25).

The proposed method and the fish way it implements allow you to create a controlled water flow over the entire length of the tract of fish passage, introducing additional resistance to the main thread, which to the maximum extent promotes the free and independent fish passage at the upstream face and ensures normal operation of the fish way.

Control of fish passing through fish conduit comes to creating fish attraction water fed from upper pond of hydraulic works into fish conduit and further into lower pond, forming favorable hydraulic conditions directly in fish conduit by changing water level drop between cross partitions by displacing partitions proper relative to bottom of fish conduit and creating overcomable velocity in swim-in holes of partitions. Partitions are displaced along length of fish conduit by driven in direction of upper pond and, simultaneously with displacement of partitions, water level drop formed between partition formed between partitions is displaced, and value of local water level drop is changed over length of fish conduit owing to nonuniform perforation of sections of partitions having different porosity.

EFFECT: provision of controllable hydraulic conditions in fish conduit contributing to effective movement of fish along its length.

SUBSTANCE: invention relates to hydraulic works designed for passing fish spawners through retaining facilities to places of spawning and fattening. Hydraulic resistance lengthwise fish conduit is formed by means of cross partitions installed along conduit and secured on cross guides at different height marks in depth marks in depth of current and made flexible of elastic material, and delivery of working water into fish conduit to create conditions for passing of fish into upper pond and attraction on fish to inlet of fish pass and subsequent changing of position of partition of partitions relative to fish conduit. Cross partitions form system of swim-in holes creating maximum hydraulic resistance to current passing through fish conduit. Lower partitions in direction of current are installed opposite to swim-in holes formed by upper partitions, thus changing paths of fish movement and total value of hydraulic resistance created by system of partitions.

EFFECT: provision of effective movement of fish to side of upper pond by regulating hydraulic resistance lengthwise fish conduit.

SUBSTANCE: invention relates to methods and facilities designed for passing fish spawners through retaining facilities to places of spawning and fattening. Method comes to delivery of transit flow from side of spillway dam, forming longitudinal screw roller along headless side of bottom fish guide sill by setting sill at acute angle to transit flow and delivering attraction water to inlet hole of trough-fish storage. When forming longitudinal screw roller, part of transit flow passing higher than bottom sill side is redistributed in direction perpendicular to side surface of bottom sill towards longitudinal axis of trough-fish storage. In case of water rise in lower pond, using closed louver slats, water tight plane is formed above upper side of sill making it possible to form bottom fish guide sill of greater height. Fish guide includes bottom fish guide sill installed at angle to longitudinal axis of fish facility and adjoining inlet part of trough-fish storage, device to control longsill current whose position can be changed by means of drive which is made in form of system of louver slats installed on upper edge of bottom fish guide sill and connected with drive. Surface of louver slats can be perforated.
