Description

The invention relates to rescue equipment, namely, devices for rescuing people on the water and can be used to equip rescue vessels to rescue people scattered on the surface of the water and lost power.

The purpose of the invention is to increase the reliability of the rescue operation.

Fig, 1 shows a device with a two-layer shell in the form of sectors, a cross section; in fig. 2 is a diagram of the vessel’s circulation when the device is dropped overboard; in fig. 3 - the device after completion of circulation and withdrawal of the tail part from operation, top view; in fig. 4 - device, axonometrics.

A device for rescuing people in water contains a cable 1 placed in a case 2 of soft, durable fabric. On either side of the cable are two gas-tight cylinders 3 of elastic material. Soft containers b and 7 of pillow type are fixed to cylinders using patch sheets 4 and 5 above and below the cable, forming, respectively, the surface and underwater parts of the wall. On the part of the length of one of the cylinders 3 along the generatrix with the help of patch sheets 8, two-layer hermetic reservoirs 9 are attached. Forming in total the sector part 10 of the device (Fig. 2). The section of the device along the length without sectors forms the tail part 11 (contains cylinders 3, containers 6 and 7).

Two-layer sealed container 9 is made in the form of sectors (Fig. 3). Each of them consists of a lower sealed chamber 12 (Fig. 1) filled with water and an upper sealed chamber 13. filled with air. The upper chamber is sealed 13 tanks 9 partition 14 is divided into the nasal 15 (at the apex teKTOpa) and the main 16 cavity. A bypass valve 17 is mounted in the partition 14. The chambers 13 and 12 of two-layer tanks 9 are connected along their perimeter by a sheet 18. At the tops of the tanks 9, the couches 20 are secured with a laid-out sheet 19 from the front part with a stocked additional cable 21. On the lower chambers 12 The bows of the containers 9 are fixed loads 22.

Between the container and the cylinder 3 there is a gap 23, which provides rotation (plays the role of a hinge) of a two-layer container 9 relative to the cylinder 3 when lowering the tanks 9 under water and lifting them above the water. Inside the cylinders 3, the soft containers 6 and 7. forming the wall, and the containers 9 parallel to the cable 1 hoses 24 and

25 filled with water and air, respectively. Filling hoses 24 and 25 are associated with corresponding general vessel systems (not shown).

Hoses 24 and 25 along their entire length, with the exception of hose 25 passing through the upper layer of containers 9, have openings (not shown) through which water and air enter the shells. From the filling hose 25 passing through the upper chambers 13 of the tanks 9. waste processes 26. The air is fed through the processes 26 to the nasal cavity 15 of the upper chamber 13. All air cylinders 3, tanks 6 of the chamber 13 are provided with safety drain plugs

27. And the containers 7, chambers 12, filled with water, are safety pipes

28. On the outer surface of chamber 13 of cylinder 3 on the side of containers 9 and shells 6 there are elastic handles 29. Beacon 30 is attached to one of the ends of the cable 1 before the device is set off overboard (Fig. 2).

The device is used as follows.

The device is placed on the vessel. After detecting people in the water, a beacon 30 is attached to one of the ends of the cable 1. The filling hoses 24 and 25 are connected to the general water and air systems. The beacon is dropped from the ship overboard and as the ship circulates around the rescued, they release the device overboard from it. Having a positive buoyancy due to air residues, gas-tight cylinders 3 and containers 6 and 7 remain on the surface of the water. The containers 9 under the action of the load 22 are submerged and assume a position close to vertical.

Simultaneously with the start of circulation, at the first stage of preparation of the device, water is supplied through hoses 24 into the lower tank 7 into working condition. As a result, device drift is reduced. The cylinders 3 and the containers 6 are deployed and occupy the position required for filling and operating the air relative to the cable 1. With some delay regarding the beginning of the filling of the container 7 with water, the gas-tight cylinders 3 and the container 6 supply air. The containers 6, supported by the cylinders 3, also assume a vertical position, which completes the formation of a wall of soft containers 6 and 7 and allows the vessel to move to its final stage (Fig. 2) - the stage of collecting the injured in the space closed by the device put it in the ring from the sector part 10 and output

tail section 11 out of service. At the same time, a vertical wall formed from soft containers 6 and 7 reliably protects those saved from falling outside the confined water space. The soft handles 29 on the containers 6 and the bottles 3 make it possible for the rescued to use the buoyancy of the device to maintain themselves independently on the surface of the water.

At the completion of the ring closure from the device section 10 on the second floor, bringing the device to a working condition and saving a group of people pull the cable 21. draped into the cushions 20. and thereby set the direction for the tank 9 to float. Then into the nasal cavity 15 of the chamber 13 through a hose 26 supply air. When an overpressure is reached, the value of which balances the negative buoyancy of the load 22, the bypass valve 17 is activated, the Air begins to flow into the main cavity 16 of the chambers 13, and the tanks 9 begin to gradually, evenly rise, lifting the rescued people out of the water. After the tanks 9 float up, their tops are pulled down by a cable 21. As a result, a bottom is formed, on the surface of which there are rescued ones.
