Description

The invention relates to the field of marine engineering, in particular to underwater moving objects (torpedoes, underwater missiles, research stations, etc.).

One of the most effective ways to control an underwater moving object (PDO) is to control it from the launch platform via cable communication lines for transmitting information, both wired and fiber optic.

When placing cable communication lines on PDO, in order to increase the control range, stringent requirements are imposed on them to minimize the cross-section of the cable of the communication line, which sharply limits its tensile strength. The main criterion for the functioning of the cable of the communication line is to reduce the tensile load on the cable of the communication line, which is achieved by eliminating the pulling of the cable of the communication line relative to the environment. Two coils with a communication line cable are used to control the PDO from the moving launch platform: one is located in the PDO, and the other is installed on the moving launch platform. Preventing the cable from getting into the communication line near the platform body, where it may be damaged, by removing the cable from the communication line to a safe distance by unwinding through the protective hose or by towing the coil with the reel of the cable for the communication line behind the platform on a cable tug of a given length. The towed coil is mounted on the PDO and is removed from the media device to a safe distance.

There are known torpedoes equipped with a towed coil with a cable for the communication line: MK24 torpedo mod.0 Tigerfish UK, torpedoes MK25 (USA) and torpedoes that use a coil with a cable reel unwound through a protective hose to communicate with the carrier’s onboard equipment (Torpedobewaffhug, M. Schiffner, KH Dohmen, R. Friedrich, Militärverlag DDR (VEB) -Berlin 1990, p. 31, 152, Bild 141).

Also known are “Method and device for unwinding a wire connecting a torpedo with a launch platform” - according to French patent No. 2.644.015 5 F 42 B 19/10, F 41 G 7/32, 1991, EPO patent No. 0504049, 5 F 41 G 7/32, B 63 G 8/42, 1992, RU 2171197 C1 (Central Research Institute named after Academician A.N. Krylov) 01/27/2001

Known application No. 2002133772/02 (035644) of December 15, 2002, which decided to grant a patent. The specified technical solution for the application was taken as a prototype.

A towed cable reel of the communication line of an underwater moving object with a launch platform equipped with a retractor of the oncoming cable of the communication line through which the cable-tug of the coil is passed. The diverter is installed on the bow of the coil and is fixed by a device for attaching it to an underwater moving object. The diverter consists of two brackets pivotally connected and spring-loaded together. When crossing the previously wound cable of the communication line, the latter enters through a cable-tow and is discharged along the outlet to the coil, preventing the cable from being pulled in water.

The disadvantage of this device, as well as the above analogues, is the possibility of crossing the cable tug with the previously wound cable of the communication line at the immersion section of the coil after it is separated from the PDO before the tap opens. The tension force of the cable tug exiting from the towing unit located on the outer surface of the towed coil creates a turning moment relative to the center of mass of the towed coil, this leads to sharp changes in orientation angles with the oscillatory nature of the lateral deviations, which is confirmed by mathematical modeling of the process of movement of the coil and, as a result, it leads to an early pickup by the cable-tug of the cable of the communication line that was previously exhausted from the PDO coil, while the communication cable hangs on cable-b IRGC and does not always reach otvoditelya counter-link cable.

The aim of the invention is to increase the reliability of the cable communication line for transmitting information between PDO and the launch platform by stabilizing the movement of the towed coil on the dive site, while the unwinding of the cable tug is performed along the longitudinal axis of the towed coil with the subsequent transition to the towing unit when picking up the coil to tow the launch platform and the creation of a stabilizing force due to the braking unwinding of the elastic element with an adjustable tightening force.

This object is achieved by the fact that in a towed coil of a cable communication line PDO with a launch platform containing a device for attaching to PDO, a return cable for the oncoming communication cable and a tug cable connected to the launch platform, the cable tug is passed through a braking device unwinding it made in in the form of an elastic element and a pressure nut with an adjustable tightening force, and the device is placed along the longitudinal axis of the coil in its rear part in the glass, while the glass is equipped with a lock for separating the device Twa upon termination of full-Towing cable unwinding followed by transfer-tug towing cable assembly when the wings for towing towed coil launcher platform.

Figure 1, 2 shows a General view of a towed coil.

Figure 3 shows the lock separating the device from the glass.

Figure 4 shows a General view of the coil and the position of the cable line when towing behind the launch platform.

The towed coil contains a housing 1 (Fig. 1) in the form of a cylindrical shell with plates stabilizing the movement of the coil, a profiled fairing 2 is installed in the bow of the shell, the tail of the shell is closed by a lid. Inside the housing 1 there are bobbins with a cable tug 3 and a cable for the communication line 4. The bobbins 3 and 4 are interconnected and form a single communication line, connectors are installed at the outer ends of the coil communication line for mating with the response parts of the cable information line. On the fairing 2, a locking device 5 (Fig. 2) for attaching the coil to the PDO is installed, consisting of two half-brackets connected by tightening bolts. A loop 6 of the cable tug is released from the bobbin 3, which is connected to the locking device 5. Between the fairing 2 and the locking device 5, a diverter 7 is mounted, fixed in the hinged supports of the fairing 2. The diverter 7 consists of three brackets 8, 9 and 10, interconnected using the hinge axes on which torsion springs 11 and 12 are installed. The lower part of the bracket 8 is connected to the cowling 2 by two tensioned springs, the bracket 9 is laid along the coil body 1, and the bracket 10 is pivotally connected to the locking device locked by a lock glass coil 13 (Figure 3). The outer end of the cable tug is passed through a braking device unwinding it, made in the form of an elastic element 14 and a pressure nut 15, with an adjustable tightening force and fixed in the tube of the launch platform. The cable tug passing through the braking device along the longitudinal axis of the towed coil does not exert force on the spring loaded sleeve 16.

When the PDO moves, the reel 3 of the cable tug begins to unwind through the braking device, while a force of 50 ... 150 N arises on the cable tug, acting along the axis of the coil and pulling it (cable tug) in line. The amount of force is regulated by the deformation of the elastic element. Upon reaching the estimated length of the unwound cable tug, loop 6 initiates unlocking of the locking device 5 with separation of half-brackets connecting the towed coil with PDO, the coil is separated from PDO and sinks before being picked up for towing by the launch platform. When picking up the towing of the coil, the cable tug acts on the spring-loaded sleeve 16 with a force greater than the counter-force of the spring 17, while the sleeve 16 moves, the ball 18 enters the annular groove of the sleeve 16 and releases the device from communication with the glass 13 mounted on the towed coil. The device connected to the bracket 10, and the brackets 8, 9, 10 of the diverter 7 by means of the springs are deployed in the same plane at an angle to the vertical axis of the coil (figure 4) with the transfer of the cable tug to the outer surface in the towing unit.

In the case of the intersection of the cable-tug of the coil with the previously wound cable of the communication line, the cable of the communication line is lowered from the cable-tug and slides under the coil along the tailgate 7. In this case, the forced movement of the cable of the communication line relative to the environment is stopped, the tensile load on the cable of the communication line is eliminated and the breakage of the cable communication line is prevented.

The effectiveness of this device is confirmed by calculation and mathematical modeling of the process of movement of the towed coil, technical documentation has been developed and prototypes of individual units have been made.
