Description

The invention relates to means for lifting sunken submarines.

Known devices for lifting sunken submarines, for example, devices for restoring buoyancy of boats in various ways:

- pumping water from the compartments with pumps;

- displacement of water from compartments with compressed air (gas), polyurethane foam;

- using inflatable soft pontoons;

- securing to the vessel of purged pontoons, etc. [1].

The disadvantages of these devices: at depths of over 40 m, special deep-sea equipment for divers is required to carry out work, which drastically reduces the effectiveness of their actions and significantly increases the cost and duration of the work.

The closest technical solution, selected as a prototype, is the “Device for lifting a submarine” [2]. The device contains a supporting flexible structure for the submarine plant connected with lifting cables and covering a flexible structure, which are made of interconnected longitudinal and transverse cables, and resembles a twin trawl, with an open bag and two pairs of towing cables. Moreover, the first transverse cable is made with bushings mounted on it with the possibility of rotation and connected at its ends with cargo-burrows.

The disadvantages of this device. A twin trawl-type network assumes only the inclined position of the lift boat in it, which leads to heavy loads on “two pairs of towing cables, and this makes the device unsuitable for lifting Kursk submarines, which have large dimensions and weight.

The purpose of the proposed device for separation from the ground, fixing at a certain height and transporting sunken submarines in shallow water, including the Kursk submarine type, is reliable fixing and subsequent transportation of sunken submarines in shallow water, including the Kursk submarine type in a short time and for reducing to minimize costly and dangerous deep-sea operations. Which dramatically reduces the cost of lifting sunken submarines.

This goal is achieved by the fact that in the device for detaching from the ground, fixing at a certain height and transporting sunken submarines in shallow water, including the Kursk submarine type, which contains a flexible metal network consisting of transverse (bearing) and longitudinal (supporting) interconnected ) ropes, rope two front, lateral hoisting ropes, flexible metal net has a length equal to or greater than the length of the sunken submarine and a minimum width of _^3/4 the circumference of the hull amidships. The first frontal rope is rigidly connected to the transverse (supporting) ropes of a flexible metal network, and the second frontal rope is connected to the first frontal rope only by its ends with the formation of common loops (thimbles). The side hoisting ropes are removable from the front of the front ropes, and on the opposite side of the flexible metal network are connected to the transverse (supporting) ropes, and the removable side hoisting ropes at one end are equipped with numbered mechanical grips for quick attachment to the corresponding transverse (supporting) ropes.

The proposed device for separation from the ground, fixing at a certain height and transporting sunken submarines in shallow water, including the Kursk submarine type, allows you to quickly put a flexible metal network under a sunken submarine, securely fix it in a flexible metal network and, while maintaining horizontal the position of the boat, transporting it in shallow water to depths that allow you to work in light diving equipment.

Of the deep-sea equipment, only a bathyscaphe is needed, equipped with a special manipulator for attaching removable lateral hoisting ropes, disconnecting traction ropes, monitoring, control and control of surface vehicles.

The proposed device consists of two frontal ropes, a flexible metal network connected to one of the frontal ropes, side removable lifting ropes and side fixed lifting ropes.

The purpose of the first frontal rope is to cut through the ground and pull the network under the hull of the sunken submarine.

The purpose of the second frontal rope is to automatically replace the first frontal rope if it breaks, without stopping the operation of pulling the network.

The purpose of the flexible metal network is the reliable fixation of the boat, the uniform distribution of the load on all elements of the device.

The purpose of the side hoisting ropes is to take the sunken submarine off the ground and hold the net with the boat fixed in it during transportation and hoisting.

In contrast to the known device, a flexible metal network evenly distributes the load, both on all network elements and on the side hoisting ropes. The advantage of a flexible metal network is that it is easy and in any place to attach additional lifting devices to it: pontoons, floats, etc., and this can be done both in advance on the surface and under water.

A flexible metal network allows you to securely fasten the boat to the boat with a minimum of deep-water operations, which make up a significant part of the cost of all lifting operations.

A flexible metal network ensures reliable transportation of the sunken submarine.

The pulling force of the frontal rope is determined by the specific pressure of the boat hull on the ground. The large contact area of the sunken submarine with the ground leads to a small specific pressure, which the frontal rope overcomes.

The invention is illustrated by drawings.

Figure 1 shows a device for separation from the ground, fixing at a certain height and transporting sunken submarines in shallow water, including the Kursk submarine type; figure 2 is a section along aa.

The first frontal rope 1 is rigidly connected with the transverse (supporting) ropes 2 of the flexible metal network 3. The second frontal rope 4 is connected to the first frontal rope 1 by its ends with the formation of common loops (thimbles) 5 and sags freely in the loops of the transverse (supporting) ropes 2, which are connected with the longitudinal (supporting) ropes 6, forming an actually flexible metal network 3. The location of the transverse (supporting) ropes 2 is determined by the weight distribution of the sunken submarine along its length, i.e. weight per meter boat.

The lateral removable hoisting ropes 7 are attached at one end to the transporting watercraft (tanker), and the other to the transverse (supporting) ropes 2 by means of numbered mechanical grippers 9. The lateral removable hoisting ropes 10 are attached to the transverse (supporting) ropes 2 in advance on the surface. Side hoisting ropes 7, 10 are made of polymer materials and can be grouped into 2-3 ropes.

The operation of the device is as follows.

The device is lowered to the ground so that the flexible metal network 3 lies with the front ropes 1, 4 along the side of the sunken boat. Two rescue vessels pulling ropes 11 stretch a flexible metal network 3 under the bottom of the boat half its width. Side removable lifting ropes are lowered 7. Using a bathyscaphe equipped with a special manipulator or a diver, flexible removable lifting ropes 7 are attached to a flexible metal network 3 by their numbered mechanical grips 9 to the corresponding transverse (supporting) ropes 2 and disconnected from the loops (buckles) 5 by traction ropes 11. The lifting and transporting vessel (tanker) selects the slack of the side hoisting ropes 7, 10. The network 3 tightly fits the lower half of the boat hull and securely fixes it. The slack of the side hoisting ropes is sampled when the tanker is fully loaded with ballast. By pumping out the ballast, the tanker smoothly tears the boat off the ground to a certain height, approximately equal to the difference between the draft of the tanker “in cargo” and “empty”.

Next, the fixed boat is transported to the intended smaller place where the boat again touches the ground. Operations are repeated: ballast injection, sampling of slack of lateral hoisting ropes, pumping of ballast, separation of the boat from the ground and transportation in shallow water.

Thus, the proposed device for separation from the ground, fixing at a certain height and transporting sunken submarines in shallow water, including the Kursk submarine, minimizes costly, lengthy and dangerous deep-sea operations.

Reliable fixing of the boat allows you to work in adverse weather conditions.

These factors reduce costs by an order of magnitude and reduce the time required to lift sunken submarines by several times.

In addition to the economic effect, the use of the proposed device also gives a military-political effect - no foreign observers, no requests for technical and financial assistance.
