Embodiment Construction

[0007] As shown in the accompanying drawings, it is a specific embodiment of the airbag that can be automatically inflated in water according to the present invention. Including: gas cylinder shell (1), spring (2), valve inner nozzle (3), reinforcement sleeve (4), valve jacket (5), positioning groove (6), top wire (7), sealing ring (8) , screw sleeve (9) and air bag (10).

[0008] Among them, the shell of the gas cylinder (1) is welded with steel plates, and a reinforcing sleeve (4) is welded at the valve where the gas enters and exits. The outermost end of valve overcoat (5) has screw thread and is used for connecting air bag (10). The accompanying drawing shows the state that the inside of the gas cylinder is filled with high-pressure gas and the air bag (10) is not inflated. At this time, the inside of the positioning groove (6) is filled with a whole piece of edible rock sugar or other non-polluting solids that can dissolve in water, and the outside is covered with paraff...

Abstract

An airbag capable of autoinflation underwater is designed in the invention. The airbag comprises a gas cylinder housing (1), a spring (2), a valve inner-nozzle (3), a reinforced sleeve (4), a valve bushing (5), a locating slot (6), a jackscrew (7), a sealing ring (8), a thread sleeve (9) and an airbag (10). When a gas cylinder is filled with high pressure gas, the locating slot (6) is filled with a whole piece of edible rock sugar, and the outside of the locating slot is sealed up with paraffin. The jackscrew (7) is screwed. Before the gas cylinder is poured into water to carry out air inflation work, a small hole is poked in the paraffin seal outside the locating slot (6) according to the sinking depth underwater. Then, the jackscrew is screwed down, and the gas cylinder and the airbag are poured into water. After the rock sugar in the locating slot (6) is dissolved in water, the spring (2) pushes the valve inner-nozzle (3) to move outward for a distance L. The valve inner-nozzle (3) is communicated with a venthole in the valve bushing (5), and high pressure gas in the gas cylinder is automatically ejected to inflate the airbag.

Description

(1) Technical field [0001] The invention relates to an air bag, in particular to an air bag with simple structure, convenient operation, safety, reliability and low cost, which can be automatically inflated in water, can be widely used in salvage operations of large sunken ships and wrecked submarines, and belongs to the technical field of maritime salvage. (2) Background technology [0002] Existing international large-scale submarine salvage method mainly contains two kinds at present: buoy drum method and hoisting method, that is to say, is equivalent to fishing the submarine from the seabed with bigger buoyancy boat or buoy drum. These two methods have the disadvantages of heavy workload, high cost, high risk and long period. (3) Contents of the invention [0003] In order to make up for the deficiencies in the prior art, the present invention provides a simple structure, convenient operation, safe and reliable airbag for salvage of large sunken ships and wrecked subma...
