Description

The technical solution relates to the rescue of ships that were in an emergency as a result of a missile from a shell or collision with a ship, or an underwater ledge, when the survivability of the ship is not recoverable and the crew with passengers is forced to leave the ship.

The generally accepted ways to save people with such complications are to launch life-saving appliances, landing people on them and quickly moving away from the vessel that is drowning. At the same time, all team members and passengers put on life jackets. These actions are provided for by all existing instructions and rules, but they can not always lead to positive results for the following reasons:

1. Launching of boats during a storm is almost impossible. onboard rolling will lead to collisions with the side and destruction of the rescue equipment.

2. Even if the rescue equipment is launched and departs from the board, people will find themselves wet before rescue at low temperature with a partially flooded boat, which, of course, cannot be acceptable for women and children.

3. The storm will not allow the boat to maintain buoyancy for a long time.

4. People in vests caught in the water have practically no chance of salvation. Usually on ships that have suffered damage as a result of the various circumstances listed above, the chance of survival is very low. In stormy weather, there will be water flowing through the deck and various technological openings that are not airtight (see "Elementary Physics Textbook" edited by Ladsberg, Volume 1, pp. 352-355).

The aim of the proposal is to eliminate these shortcomings, namely, rescue the ship with people, and in relatively comfortable conditions, save the cargo, which is important if the cargo is environmentally hazardous, for example, if the ship is military and has nuclear missiles on board, to reduce pitching and load on the hull vessel, which leads to the destruction of the integrity of the hull

The goal is achieved using a rescue device. The explanation of the method.

1. Dangerous damage to the vessel is always below the waterline, so water will immediately begin to flow. 2. The rescue system can be switched on in two ways, the first by an electrovalve by pressing a button from the captain’s cabin, and the second by opening a valve on a can of compressed air. With the supply of compressed air, a life belt is opened, an air sleeve is formed along the entire vessel along the waterline which will in no way allow the vessel to sink, on the contrary it will give better stability on the water and will be less prone to rolling from the storm. A vessel with such a system can be in the water for any time, it is possible to repair the vessel on the spot, and if repair is not possible, then towing the vessel to the repair docks. As a result, we get the salvation of people, cargo and ship, which costs a lot of money.

Thus, all the goals set forth above are achieved.

All of the above allowed:

1. Create a technologically simple device to keep ships afloat, as well as save the lives of people, the cargo of the ship, and the ship itself.

2. Get an inexpensive rescue device.

3. The minimum cost of maintaining the system.

4. Reusable use of the rescue system.

5. It is possible to use the system in submarines and other submersible vehicles.

Figure 1 shows the ship, and it installed a rescue system in assembled form. Figure 2 shows the rescue system in action. Figure 3 shows a schematic diagram of the supply of compressed air to the belt. Figure 4 shows a schematic diagram of the fastening of the rescue belt to the hull of the vessel. Figure 5 shows the belt assembly in section in assembled form, and in action.

The rescue system for ships contains: 1. the ship itself; 2. rolled-up flexible rescue belt mounted on a ship; 3. The belt consists of high-strength nylon material impregnated with rubber; 14. Belt pressure limiting valves; 15. dividing partitions dividing the belt into four parts; 4. slings wrapping around this belt, slings are made of the same material, rolled up in several layers; 5. fastenings connecting the slings of the belt along the stern of the vessel to the stiffeners of the vessel, made of stainless steel; 6. shows the stiffeners of the vessel where the sling is attached; 7 technological holes in stiffeners; 8. shows a fitting for supplying air to a life belt made of stainless metal; 16. high pressure hoses; 9. cylinders with compressed air, compressed air can be supplied in two ways, the first - 17. an electrovalve, turning on the button from the captain’s cabin and the second, spare, mechanical way by opening 18. the valve on the cylinder manually for supplying compressed air to the flexible belt; 10. the cover closing belt in a folded form serves to protect the belt from mechanical damage made of a metal profile; 11. The magnet serves as a lock to close the casing; 12. casing hinge; 13. The metal plate of the casing lock.
