The invention relates to sonar technology and relates to the creation of devices for setting and sampling (OLA) flexible extended towed antennas (GPBA) on submarines and surface ships.

GPBA designed to receive sonar information, pre-processing and transmission to the on-Board apparatus for forming stacks of directional characteristics and secondary processing. Towed antennas have a length far greater than the linear dimensions of the carrier-ship, and with a cable-tow are from the ship to a distance sufficient to reduce the level of own ship's noise. Usually GPBA on technological considerations collected from the antenna module.

The necessary manipulations associated with the production and harvesting of GPBA, is performed by means of devices for setting and sampling (OLA). Such devices [Wahrani, Saaserhof, Gevallen, Naval sonar equipment, S. Petersburg : Nauka, 2004, P.62] intended for storage, etching into the sea to work for its intended purpose, towing and winder, GPBA after work. As a rule, OLA includes a winch drum which is wound sequentially connected in one linear system of cable-tow, GPBA, and, in some cases, the overpass for HPBA in which razmisha the raised part of HPBA. This viaduct is a long cylindrical shell (tube store), through which GPBA extends from the winch to the stream.

Known towed the vessel GPBA containing acoustic receivers sound pressure and electronic devices pre-processing and compression of the information, placed inside a sealed hose shell filled with liquid or pseudogenes (gel) filler (patent RF №2136019 dated 27.08.1999, No. 2229734 from 27.05.2004). The length of such antennas may be from several tens to several hundreds of meters. Depending on the method of setting and type of the vessel-towing antennas on the ship are either on the winch drum OLA, or partially on the drum and partially in the tubular store for evacuation (etching) HPBA with winch in its formulation overboard. In some constructive solutions winch and tubular storage form a single loop seal, in the other - winch and tubular storage are not sealing correctly. [Wahrani, Saaserhof, Gevallen, Naval sonar equipment, S. Petersburg : Nauka, 2004, p.62]. For etching the antenna hydrodynamic method, in which the contour of the sealing winch tube store, or only in a tubular storage, an excessive (relative to esname hydrostatic) pressure. On GPBA due to the presence in the water stream pressure gradient occurs tractive effort, as the thread is about to exit the tubular store [RF patent №2171197 from 24.01.2000]. When you enable the winch to stage occurs etching GPBA of the tubular storage.

However, when a differential pressure is created at the tube store, there is a method of setting is effective only when GPBA is completely within the tubular storage, and the winch is only the cable-tow. A significant difference in the diameters of GPBA (60-80 mm) and cable-tow (15-20 mm) and significantly higher radial stiffness of the cable-tow allows you to create the entrance of the tubular storage effective lip seal [RF patent №2171197 from 24.01.2000] and to ensure that the pump needed to put GPBA traction. In this case, if the moving speed of GPBA in a tubular storage will be greater than or equal to the linear speed of bleed from winch cable-tow, the production of HPBA will be in tension and the cable-tow, even on the winch will not produce slack ("butini"). I.e. a necessary condition for the successful staging of GPBA in this case is (besides creating the shell of GPBA necessary traction) providing a linear velocity etching cable-book the Ira with winch, less than or equal to the speed of movement of GPBA in a tubular storage determined by the magnitude of the pressure gradient when creating excess pressure. When this braking force due to the tension bleed from winch cable-tow must be less traction on GPB.

At large apertures GPBA, when most of GPBA wound on the winch drum, and the smaller is the tubular store, there are problems in which the known method is difficult to implement for the following reasons. Unlike cable tow for HPBA impossible to install lip seal, as this will cause damage to the shell of HPBA and the development of functional nodes of GPBA inside the shell. However, due to the lack of a uniform contour of the sealing becomes impossible synchronization variables in time linear velocities winder antenna with winch and its movement under the action of the pressure gradient in the tube store.

Due to the lack of synchronization of the speeds of etching GPBA with winch (V_GPBAand flow in a tubular storage in the case of V_GPBA>V_SWEATbegins "RAID" Slavov ("Butina") GPBA, its bending and jamming at the entrance to the injector, and the fracture of GPBA at the approach to the end flange. At V_GPBA<V_SWEATdecreases traction control, winch slows down the production and the walks stop GPBA in tube storage, V_GPBA>V_SWEATthat leads to the formation of butini and fracture antenna at the approach to the end flange. Thus, setting GPBA using the described system, not with the General contour of the sealing winch and tube store, almost impossible.

These difficulties are partially eliminated in the device (U.S. patent No. 5788222 from 04.08.1998 g) for the production and selection of antenna modules GPBA in tube storage, in which occur the test antenna modules under high pressure. The antenna module HPBA has a length of tens of meters, while GPBA hundreds of meters.

The device and method according to U.S. patent No. 5788222 from 04.08.1998, are most similar analogues in the technical solution of the present device and method.

Traction on the antenna module GPBA this device is not a stream of water, and with the help of a mechanical traction device.

Mechanical pulling device includes a tubular vault, formed from a set of pipes which are rigidly and tightly connected flanges. The inner diameter of the extended tubular store larger that the outer diameter of the antenna module GPBA. Inlet and outlet tube store has two winches, each in the form of a drum with wheels and a motor for rotation.

The fore end of an antenna module GPBA secures the flat ribbon resistant to friction, belt width sufficient to have located the antenna module GPBA, so that the total size of the ribbon thickness and diameter of GPBA in cross section were less than the internal diameter of the tubular storage. Resistant to friction tape has a transverse flexibility sufficient to repeat the shape of the inner surface of the tubular section of the store, with which it is in contact and prevents frictional contact of the antenna module GPBA with the inner surface of the tubular storage when pulling, and thus protects it from scratches and damage. The length of the tape several inches shorter than the tube store. Before installation in the tubular store the antenna module GPBA is located on the long roller tray.

The antenna module GPBA by gravity in contact with the surface of the traction belt during rotation of the winch due to the friction force extends through the tubular store. Depending on the operation (part of the antenna module GPBA in a tubular storage or evacuation from it) is one of the two winches, and the second is in the neutral position. Mechanical traction device is a missed through the tubular storage tape and the associated two ropes, one of which has a detachable connection (tensioner), regulatory Natai the tion system, driving the tape when winding or winding on the drum corresponding to the winch. Available on tape mechanical traction device technological cuff capture captures nasal (when tightening) or stern (etching) connectors antenna module GPBA. On both ends of the tubular storage installed running rolls to facilitate the winding of the cables on the drums of the two independent winches.

Thus, the method of setting the sampling device of the prototype includes the following operations:

installation tape mechanical traction device in the tubular store,

connection end cables, pre-wound on the reel of the winch arm and the sample with the ends of the tape,

- creating tension with the tensioner

- consolidation of technological cuff capture on tape mechanical traction device

- manual switch-on winch productions mechanical traction device and lifting the antenna module GPBA in the tubular store,

- manual switch-on winch sampling traction device and the evacuation of the antenna module GPBA of the tubular storage.

The main problem solved by the prototype, is to reduce the complexity of the operations of setting and selection antenna module GPBA in tube storage, as compared with the preceding is adequate solutions where it was necessary at least 3 people to manipulate the antenna. The mode of operation of the winches is determined by one operator managing the process of setting using the foot-operated.

A disadvantage of this device is the placement of the antenna module GPBA to installation in the tubular storage on a long roller tray, not related to device performances-sampling, the need to use the drive two independent winches and manual mechanical mounting module GPBA traction to transport the tape at each manipulation. Another drawback of the solution of the prototype is to design a mechanical traction device, which contains a flat belt and buckle to it manually cables, which makes it impossible to use for setting the sampling extended GPBA on ships in the automatic mode in different operating conditions, for example under water.

Objective of the claimed invention aims to remedy these disadvantages of the known technical solutions, while the technical result is the possibility of setting-sampling extended GPBA leaking through the long tubular store by using mechanical traction device in automatic mode without mechanical fasteners antennas is s to transport the traction device and without education "butini", resulting in damage to HPBA.

To ensure the technical result in the device setting-sampling (OLA) flexible extended towed antenna (GPBA)containing the winch in the form of a drum with wheels and drive its rotation, a tubular storage in the form of a set of interconnected flanges of the pipes, at the entrance of which is installed winch, bypass rollers, traction mechanical device with a tensioner, passing through the tubular store and running rolls, technological cuff capture GPBA and technological drum mounted on the outlet tube store, introduced new features, namely: it is provided with a return pipe mechanical traction device, and one of the flanges of the winch is provided with an additional compartment for fast mechanical traction devices, with mechanical traction device made in the form of a cable passing through the tubular store, bypass rollers and return line, and use the tensioner closed in a loop on the rim of the additional compartment on the rope with step n installed thrust bearing, and technological cuff grip installed on the section of GPBA placed in a tubular storage, and secured along its length at intervals that are multiples of n, and the inner diameter of each technological cuff capture is equal to min the maximum outside diameter of GPBA, its outer diameter smaller than the inner diameter of the tubular storage, the sum of the outer diameter of technological cuff capture and outer diameter of the thrust bearing larger than the inner diameter of the tubular storage, and the outer diameter of HPBA and the outer diameter of the thrust bearing is less than the internal diameter of the tubular storage, while the radius of the rim of the additional compartment is equal to the radius of winding of the last layer of GPBA on the winch drum, and the Creek rim has a perforation increments n, and the sample sizes of the perforations provide accommodation resistant sleeves.

To ensure the technical result proposed a new method for production and selection of HPBA.

For this purpose, in the known method setting and sample GPBA, including the placement of GPBA in a tubular storage and installation of mechanical traction device with tensioner, introduced the following new features: installation of a mechanical traction device made in the form of a cable with installed thrust bushings, produced by pulling from the rim of the additional compartment of the drum through the tube store, then through bypass rollers and return line to the rim of the additional compartment on which the cable close in a continuous loop, with the tensioner on the rope pick up the slack so that the thrust bearing, ustanovlennye rope, went into the perforation holes on the rim of the additional compartment without the possibility of slack, make full winding of GPBA on the winch drum, by the end of GPBA technological attach the cable is passed through a tubular storage and secured to the second end of the technological drum mounted on the outlet of the tubular storage, winch in manual mode include etching and vinataba in tension technological rope on technological dryer, make part of GPBA in tube storage, when etching GPBA with the winch on the length n, stop the winch and at the entrance to the tubular store on GPBA mount technology cuff capture so that its front on respect to the winch end mechanically in contact with the back towards the winch end thrust bearing, consistently repeating the etching of GPBA with the winch on the length n, on the part of GPBA that in the normal mode is a tubular storage, fix technological cuff capture when GPBA is in a tubular storage position, the winch off and GPBA technological disconnect the cable, then further setting and sampling GPBA carried out in automatic mode.

The basic idea of the invention is to create a unit in which the ejection of the antenna in the thread of the tubular kept the and by using the thrust bushings mechanical traction device, which is driven by means of the winch unit, on which is wound GPBA. On the rim of the additional compartment winch drum infest the two ends of the rope traction device, passes through the tubular store and return line, and connected to the retractor in a closed loop. Rim additional compartment winch OLA plays the role of a drive (similar to a Bicycle sprocket). During the rotation of the winch OLA thrust bearing mechanical traction device engages with technological cuffs grip mounted on the antenna, and the antenna lead movement (similar to the links of a Bicycle chain), moving it along the tubular storage in the stream, and the speed of motion of the antenna coiled with a winch, and the speed of a mechanical traction device synchronous, because they are driven by a common drive winch OLA. This excludes education "butini", malfunctions of the unit and provides automatic setting of the antenna from leaking tubular storage in the stream.

The essence of the invention illustrated by figure 1, 2, 3, where figure 1 shows the design of the proposed OLA, figure 2 shows a longitudinal section of the tubular storage during joint movement thereon rope mechanical traction device with thrust bushings and parcel of GPBA with technological cuffs the mi-capture Fig 3 is a cross section of the tubular storage, Fig 3A) - section along AA and figb) - the cross section for CENTURIES.

The proposed OLA (figure 1) consists of the drum 1 winch with wheels and a motor for rotation, a tubular storage 2 in the form of a set of interconnected flanges of the pipes, the cable 4 mechanical traction device, which increments n installed thrust bearing 10. In one of the flanges of the drum 1 has an additional compartment 9 to rewind the cable 4. In the flange 9 with the step n is perforated (figure 1 not shown), a sample of which correspond to the dimensions of the thrust bushing 10. The cable 4 is closed in a loop using the tensioner 5, made for example in the form of a clamp. Part of a loop of wire 4 is placed in a tubular storage 2, and the part after bypass rollers 3 in the return line 8. Plot GPBA 7 with technological cuffs 6 capture is a tubular storage 2, the remainder being wound on the drum 1 of the winch. Technological drum 11 with the technological rope 12 is installed at the outlet of the tubular storage 2.

Description of the operation of the device it is advisable to combine with a description of the method.

Before placing on the drum 1 winch OLA antenna 7 on the rim of the additional compartment 9 of the drum 1 having the two ends of the rope 4 traction device, passes through the tubular vault 2 and the return line 8, and connect the tensioner 5V closed loop. Rim additional compartment 9 with samples, performs the role of an actuator similar to a Bicycle sprocket. During the rotation of the drum 1 thrust bearing 10 mounted on the cable 4 (similar to the links of a Bicycle chain), engages with the rim of the additional compartment 9 and the lead wire 4 in motion, moving it along the tubular storage 2.

When you first install GPBA 7 produce a full winding of GPBA on the drum 1 winch OLA, by the end of GPBA 7 technological attach the cable 11 is passed through a tubular storage 2 and the fixed second end on technological drum 12 mounted on the outlet tube of the store. The winch unit in manual mode include etching and vinataba in the tightness of technological rope 11 on technological drum 12, a part of GPBA in a tubular storage. When etching GPBA with the winch on the length n, stop the winch and at the entrance to the tubular vault 2 on GPBA mount technology cuff 6 capture so that its front towards the winch end mechanically in contact with the back towards the winch end thrust bearing 10, sequentially repeating the etching of GPBA with drum 1 winch on the length n. The plot of GPBA that in the normal mode is tubular vault 2 fasten the cuff 6. When GPBA takes tubular hranilishe position, the winch off and GPBA technological disconnect the cable 11, and then further setting and sampling GPBA carried out in automatic mode.

When you enable the winch to the formulation of the thrust bearing 10 cable 4 mechanical traction device "push out" the antenna 7 of the tubular storage 2 in the stream.

Since the radius of the rim of the additional compartment 9 mechanical traction device 4 is equal to the radius of the upper layer of GPBA 7, the drum 1 winch, enabling the winch to the establishment of the antenna 7 in the flow velocity of motion of the cable 4 to the tubular storage 2 corresponds exactly to the linear speed of movement of the spool with winch 1 of the first upper layer GPBA 7, since the cable 4 and GPBA 7 are driven by a common drive-winch unit and have the same angular and linear velocity. After turning the winch on the etching of a mechanical traction device transports in the flow of GPBA 7, fitted cuffs 6. Further staging is almost without mechanical traction device under the action of hydrodynamic forces wrapping the etched part of GPBA 7, the linear speed of which is relative to the linear speed of the cable 4 is increased. Mechanical traction device does not prevent the further production of GPBA 7 (figb), since the diameter of GPBA 7 and the diameter of the cable 4 with hard liners who AMI 10 less than the internal diameter of the tubular storage 2. When the sample GPBA 7, when the tubular store 2 returns part of GPBA 7 installed technological cuffs grip 6, the movement of the wire 4 does not prevent a part of the antenna. Return line 8 to mechanical traction device can be installed regardless of the trace of the tubular storage 2. While implementation of the proposed mechanical method setting and sample GPBA allows operation without the use of a hydraulic system leaching, does not require the introduction into the design of the OLA optional winch to drive a mechanical traction device and provides automatic synchronization of the speed vytravlivaetsya GPBA and speed of a mechanical traction device that eliminates the formation of slack and overlapping antenna on the winch.

Thus, the creation of a mechanical traction device, which is driven winch unit on the drum which is wound GPBA, provides the function of automatic setting and sampling HPBA and the problem of automatic synchronization of the speeds of GPBA and mechanical traction device in the process of setting and sample, provides a solution to the problem of setting GPBA in unsealed tubular storage and eliminates failures OLA during deployment and retrieval of HPBA.
