Description

The invention relates to underwater technology, namely to underwater search towed systems.

There are many two-link towed systems, for example, “Towed underwater search system” according to copyright certificate No. 1216914, MKI B63B 21/66, containing a deepener connected by a cable-cable to a carrier vessel and an underwater search apparatus connected to a deepener by an intermediate cable-cable.

A common drawback of this and similar systems is the complexity of the descent and ascent process due to the presence of two towed underwater objects - a deepener and a search apparatus.

Closest to the technical nature of the claimed invention and taken as a prototype is also "Underwater towed search system" according to copyright certificate No. 701042, MKI B63B 21/00, containing a towing vessel, a towing cable with a deepener, an intermediate lightweight cable and light underwater search engine with instruments and tail movers located in the vertical and horizontal planes.

The main disadvantage of this prototype is the complexity of the hoisting operations due to the presence of two towed objects (links) - a deepener and a search apparatus.

The technical problem to be solved of the proposed invention is the elimination of these drawbacks, namely: the creation of a highly efficient underwater towed search system that allows to simplify its operation.

This object is achieved by the fact that in an underwater towed search system comprising a towing vessel, a towing cable, a heavy carrier-depth device mounted on the running end of the cable-cable, and a light equipment carrier connected to the deepener by a lightweight cable-cable and having thrusters and a deepener are equipped with a winch and its design includes a niche open from the aft end, the dimensions and configuration of which are consistent with the external forms of a light carrier, except for , a longitudinal guide is made above said niche, on which a movable carriage spring-loaded towards the depth of the depth of the depths is installed, having a die for passing a lightweight cable cable, the root end of which is stocked through a guide roll and mounted on the winch drum, in addition, the light carrier is equipped with a vertical reversible a thruster with an automatic control system located at the aft end of a light carrier.

The invention is illustrated by drawings:

The submarine towed search system comprises a towing vessel 1, a towing cable-cable 2, a heavy carrier-deepener 3, mounted on the running end of the cable-cable 2, and a light carrier of equipment 4 connected to the deepener 3 by a lightweight cable-cable 5. Heavy carrier- the deepener 3 is equipped with a winch 6 and in its design a niche 7 is open, which is open from the aft end, the dimensions and configuration of which are consistent with the external forms of the light carrier 4, in addition, a longitudinal guide 8 is made over the niche, on which a swivel carriage 9 is installed, spring-loaded towards the stern of the deepener, having a die 10 through which a lightweight cable cable 5 is passed, the root end of which is stocked through a guide roll 11 and mounted on the drum of the winch 6, in addition, the light carrier 4 is equipped with a vertical reversing thruster mover 12 with an automatic control system located in the aft end of the light carrier 4.

In this particular case, the carriage is spring-loaded using, for example, a tension spring 13 connected to the carriage 9 with a cable 14 stored through the chain hoist 15.

This underwater towed search engine works as follows:

Before launching from the vessel 1, the light carrier 4 is located (previously placed) inside the niche 7, the lightweight cable cable 5 is wound on the winch drum 6. The cable 14 is tensioned by a spring 13, the carriage 9 is in its frontmost position. In this configuration, the system is discharged overboard the vessel 1 and lowered by bleeding the cable 2 to a predetermined depth. The descent is carried out mainly in the drift mode or at the slowest speed of the vessel. Upon reaching the specified depth, the light carrier 4 is removed from the niche 7. For this, the ship is given a turn - the winch 6 is turned on to issue a lightweight cable cable 5 and the carriage 9 due to the force of the spring 13 acting through the chain hoist 15 and the cable 14, is moved towards the stern of the deepener 3 and, resting on the nose of the light carrier 4, pushes it out of the niche 7. The hydrodynamic resistance of the light carrier also contributes to the withdrawal of the light carrier from the niche. Having reached the rear stop, the carriage 9 stops, the lightweight cable cable 5 is issued by the winch 6 to a predetermined length. Then the winch is stopped and the system is towed in the configuration shown in figure 2 (two-link system). Before lifting from a depth, the towed system again turns into a single-link system, for which a light carrier 4 is pulled into the recess 7 of the deepener 3. At the same time, the winch 6 is turned on to select the cable cable 5 and the carrier 4 is pulled to the burrower 3 until it stops in the carriage 9. Continuing to rewind the lightweight cable-rope to the winch drum 6, pull the carrier 4 into the niche 7 of the deepener. In this case, the carrier 4 pushes the carriage 9 with its nose and, overcoming the force of the spring 13, advances the carriage 9 in front of itself until it stops, after which the winch 6 is turned off. The moment of carriage stop and winch shutdown is determined, for example, by the operation of the limit switch (not shown in the drawings).

When towing the system under conditions of sea waves, the deepener, being suspended at the running end of the cable 2, performs vertical and angular vibrations, which makes it difficult to retract the light carrier 4 into the niche 7. The vibrations of the deepener occur mainly in the longitudinal vertical plane. In this device, the carrier 4, when pulling it all the way into the carriage 9, is connected with the burrower at the point of contact with the die 10 and the vertical movements of the burrower 3 and the carrier 4 become connected. It remains to coordinate their movement along the angle of the trim. For this purpose, a reverse thruster with an automatic control system 12 is installed in the aft of the light carrier 4, due to the operation of which the angle of the trim of the carrier 4 is regulated and, thereby, the angle of the trim of the deepener and the light carrier is adjusted while the latter is pulled into the recess 7 of the deepener 3 .

Compared with the known analogues, this invention “Underwater towed search system” due to the constructive possibility of integration at the stages of descent and lifting two towed objects into one allows to simplify the operation of the system, thereby obtaining this system highly efficient in operation.
