Abstract

FIELD: raising of damaged submarines. SUBSTANCE: device has underlying flexible structure connected with raising ropes and embracing flexible structure; both structures are interconnected forming conical bag. Underlying flexible structure is brought under submarine by towing rescue ships. Underlying flexible structure is positioned under embracing flexible structure. Then submarine is raised to surface by means of raising ropes or towed to area adequate for further raising to surface. EFFECT: enhanced efficiency. 3 cl, 3 dwg

Description

 The invention relates to technical means for lifting sunken ships, especially submarines.

 Several devices are known for hoisting wrecks. For example, devices that pump air into waterproof compartments and have cables inserted under the vessel into washed channels, etc.

 Closest to the proposed is a device for lifting sunken ships, containing surface boats, which are equipped with hoisting mechanisms with a cable block system equipped with brakes, and ballast counterloads placed along the sides of the boats and equipped with pipes for supplying compressed air.

 However, these devices are not suitable for raising submarines due to technical inadequacy and slowness, especially in conditions of reconnaissance, military operations, secrecy, etc.

 Known cases of small submarines getting into fishing trawls. But despite the fact that there are many designs of trawls, their strength and structural features, as well as the power of the ship’s winch, the buoyancy and stability of the vessel does not allow the use of existing structures for raising submarines.

 The proposed device is devoid of these drawbacks and allows you to quickly raise or tow to the right place (for example, in shallow water) sunken, in distress or serviceable enemy submarine.

 The purpose of the invention is to reduce the lifting time of the submarine and increase the reliability of the structure.

 This goal is achieved by the fact that a robust, flexible construction, resembling a twin trawl, with an open bag and two pairs of towing hoisting cables, contains a front cable equipped with bushings, cargo-deepeners and upper flexible elements with positive buoyancy.

 In FIG. 1 shows a device, a top view; in FIG. 2 - device at the time of capture of the submarine; in FIG. 3 - operation of the device when lifting a submarine.

 The proposed device (Fig. 1) consists of a front underlying part 1 and an enclosing part 2 in the form of a truncated net cone. The basis of the device is transverse 3 and longitudinal 4 flexible elements. The lower ones can be made of steel or durable synthetic ropes (ropes), and the upper ones can be made of polypropylene or other ropes with positive buoyancy. The front cable 5 should be the most durable, and to reduce its grinding, put on the sleeve 6.

 To open the conical part 2 to it from above and from the side are fixed floats (kitchen) 7 with positive buoyancy. In order for the structure to quickly sink to the bottom, weights are attached to the front part 1 - depthers 8. For towing and lifting the device and the boat, towing cables 9 and auxiliary cables 10 are used.

 Flexible elements are interconnected by brackets, which allows you to quickly replace them in a rush.

 The operation of the device is as follows.

 With the help of instruments (echo sounder, underwater television) or divers, the place and position of the submarine, the nature of the soil, etc. are determined. Having marked the place with a buoy, they depart from it at the required distance. The proposed device is discarded from the carrier vessel. Then, towing cables are ejected from it and the twin vessel (or three vessels) until the device is lowered to the ground and the cables are sagged. After this trial, the twins move in pairs, leaving the boat between them. The device is towed along the bottom, then its front part goes under the boat, and the cone rests on the superstructure and covers part of its hull (see Fig. 2). In the future, ships can tow the boat to the right place, and then start lifting it, or it can start immediately. To do this, the ships include winches and begin to choose lifting cables. Before this, ships are anchored, if depth permits. If necessary, a third pair of vessels and lifting cables can be connected to the end of the lift (see Fig. 3). Lifting cables are sampled slowly and evenly, possible distortions are controlled by the standards applied to the cables, for example, after 25 m.

 The economic effect of the use of the proposed device is expressed in the fact that the rescued submarine can be used for further operation, the enemy does not get the secret information on our boat. Crew members can be rescued.

 In the case of raising a boat of a foreign country, secret information, prisoners of war and other values may be obtained. New submarines cost millions of rubles. Consequently, the economic effect will be expressed in millions. (56) Copyright certificate of the USSR N 1439033, cl. B 63 C 7/02, 1987.
