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 casing 1, spring 2, valve inner mouth 3, reinforcement sleeve 4, valve casing 5, positioning groove 6, jacking screw 7, sealing ring 8, screw sleeve 9 and air bag 10.

[0008] Among them, the gas cylinder casing 1 is welded with steel plates, and a reinforcing sleeve 4 is welded at the valve for entering and exiting gas. The deflation valve is composed of a valve casing 5 and a valve inner mouth 3. There are threads for connecting the airbag 10 . Shown in the accompanying drawing is the state that the inside of the gas cylinder is full of 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 sealed with paraffin...

Abstract

The present invention designs an air bag that can be automatically inflated in water, including: a gas cylinder shell (1), a spring (2), a valve inner mouth (3), a reinforcing sleeve (4), a valve jacket (5), and a positioning groove ( 6), top screw (7), sealing ring (8), screw sleeve (9) and air bag (10). When the inside of the gas cylinder is filled with high-pressure gas, the inside of the positioning groove (6) is filled with a whole piece of edible rock sugar, the outside is sealed with paraffin, and the top wire (7) is tightened. Depth, poke a small hole in the paraffin seal outside the positioning groove (6), unscrew the top screw, then put the cylinder and air bag into the water, wait for the rock sugar in the positioning groove (6) to dissolve into the water, the spring (2) Push the inner mouth of the valve (3) to move outward for a distance L, the inner mouth of the valve (3) communicates with the vent hole on the outer casing of the valve (5), and the high-pressure gas in the gas cylinder is automatically ejected to fill the air bag.

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...
