Abstract

A gas bag capable of autoinflation underwater is designed in the invention. The gas bag 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 a gas bag (10). When the gas bag 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 bag and a gas cylinder are poured underwater to carry out air inflation work, a small hole is poked in the paraffin seal outside the locating slot (6) of the gas cylinder according to the sinking depth underwater. Then, the jackscrew is screwed down, and the gas cylinder and the gas bag are poured into water. After the rock sugar in the locating slot (6) is dissolved underwater, the spring (2) pushes the valve inner-nozzle (3) to move outwards 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 gas bag.

Description

The gas bag of automatic inflating under water
(1) technical field
The present invention relates to a kind of gas bag, especially a kind of simple in structure, easy to operate, the safe and reliable cost low energy gas bag of automatic inflating under water, can be widely used in, in the salvage operation of large-scale wreck and wrecking submarine, belonging to maritime affairs salvage technical field.
(2) background technology
Existing large-scale submarine salvage method mainly contains two kinds in the world at present: floating drum method and lifting method, be namely equivalent to ship or the floating drum of larger buoyancy, submarine be dragged for up from seabed.These two kinds of methods have work capacity large, and expense is high, have a big risk and long shortcoming of cycle.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, provide a kind of simple in structure, easy to operate, the salvage gas bag of safe and reliable large-scale wreck and wrecking submarine, when operation, gas bag is drawn in the cabin or corridor of shipwreck and wrecking submarine with diving robot, gas bag automatic inflating, water in cabin or corridor is squeezed away to shipwreck floating.
Be characterized in, in the valve of the gas tank of inflating to gas bag, in the middle of mouth, there is an axial air extractor vent, and a horizontal communication hole, the pressure at the two ends of each air extractor vent is identical, therefore no matter gas tank outside and inner pressure have muchly, do not affect spring mouth in valve is ejected.Valve overcoat inside the position of air extractor vent have an annular groove in order to compensation flap in the air pressure of mouth air extractor vent periphery, facilitate moving axially of mouth in valve.Between mouth, have grease in valve overcoat and valve, play lubricated and sealing function, when usefulness is to carry out shipwreck and wrecking submarine salvaging with this gas bag, the ship of suing and labouring need not be very large, and personnel need not be a lot, can reach canoe and rescue the effect of large ship.
(4) brief description of the drawings
Accompanying drawing is the present invention's gas bag structural representation of automatic inflating under water.
Wherein: 1 gas cylinder shell, 2 springs, mouth in 3 valves, 4 reinforcing sleeves, 5 valve overcoats, 6 positioning grooves, 7 jackscrews, 8 seal rings, 9 swivel nuts, 10 gas bags.
(5) detailed description of the invention
Be the present invention's a kind of specific embodiment of the gas bag of automatic inflating under water as shown in drawings.Comprise: gas cylinder shell (1), spring (2), mouth (3), reinforcing sleeve (4), valve overcoat (5), positioning groove (6), jackscrew (7), seal ring (8), swivel nut (9) and gas bag (10) in valve.
Wherein gas cylinder shell (1) forms with Plate Welding, and welds a reinforcing sleeve (4) at the valve place of dress input and output gas
Venting valve is made up of mouth (3) in valve overcoat (5) and valve, and the outermost end of valve overcoat (5) has screw thread to be used for connecting gas bag (10).It shown in accompanying drawing, is the state that gas cylinder internal is full of high pressure gas and gas bag (10) unaerated, now positioning groove (6) inside is full of the edible rock sugar of a monoblock or other meets the free of contamination solid that water can dissolve, outside seals with paraffin, positioning groove (6) is drum-shaped, jackscrew (7) is tight condition, before gas bag and high-pressure gas bottle are dropped into and implement salvage operation under water, the degree of depth sinking under the water according to gas cylinder, the paraffin envelope of positioning groove (6) outside is disclosed out to a sizeable aperture, again jackscrew (7) is unclamped and screwed down, then gas cylinder is dropped under water together with the gas bag linking together (10), now the rock sugar in positioning groove (6) can be dissolved under water lentamente, finally, spring (2) promotes outwards miles of relative movement L of mouth (3) in valve, air extractor vent in valve on mouth (3) and valve overcoat (5) communicates, high pressure gas in gas cylinder automatically ejection are inflated to gas bag (10), after the gas bag inflation of packing folding, launch.
This invention is the repeatedly Reusability of gas bag of automatic inflating under water, when inflating in empty gas cylinder, process is contrary, first jackscrew (7) is tightened, after having inflated in gas cylinder, unclamp jackscrew (7), then mouth in valve (3) is long to the inside jacking distance L, jackscrew (7) is tightened, and the edible rock sugar melting to the interior injection heating of positioning groove (6), cooling rear outside seals with paraffin.
Between the overcoat (5) of reinforcing sleeve (4) and venting valve, can, with being threaded, also can be soldered to together.
Gas cylinder connects together by swivel nut (9) with gas bag (10), and intermediate cryptographic seal (8) sealing, prevents gas leakage.
