Abstract

The present invention design it is a kind of can in water automatic inflating air bag, including:Cylinder package(1), spring(2), mouth in valve(3), reinforcing sleeve(4), valve overcoat(5), locating slot(6), jackscrew(7), sealing ring(8), swivel nut(9)And air bag(10).When gas cylinder internal is full of gases at high pressure, locating slot(6)Inside eats rock sugar full of a monoblock, and outside is sealed with paraffin, jackscrew(7)Tighten, before implementing inflation operation in gas cylinder input water, according to the depth of submerged, by locating slot(6)The paraffin envelope of outside discloses out an aperture, then jackscrew is screwed down, and then puts into water gas cylinder and air bag, waits locating slot(6)After interior rock sugar is dissolved into water, spring(2)Promote mouth in valve(3)It is displaced outwardly the mouth in L, valve(3)With valve overcoat(5)On passage communicate, the gases at high pressure in gas cylinder automatically spray be full of air bag.

Description

Can in water automatic inflating air bag
(One)Technical field
Especially a kind of simple in construction, easy to operate the present invention relates to a kind of air bag, safe and reliable cost low energy is in water The air bag of automatic inflating, in the salvage operation that can be widely applied to large-scale wreck and wrecking submarine, belongs to maritime affairs salvage technology Field.
(Two)Background technology
Current large-scale submarine salvage method existing in the world mainly has two kinds:Floating drum method and lifting method, that is, quite Submarine is dragged for up from seabed in the ship or floating drum of bigger buoyancy.Both approaches have workload big, and costly, risk is big With the shortcoming of cycle length.
(Three)The content of the invention
The present invention in order to make up the deficiencies in the prior art there is provided one kind it is simple in construction, easy to operate, safe and reliable is big Air bag, is drawn to the cabin of shipwreck and wrecking submarine by the salvage air bag of type shipwreck and wrecking submarine with diving robot during operation In room or corridor, air bag automatic inflating squeezes away the water in cabin or corridor, and shipwreck floats.
It is characterized in, to there is an axial passage in the middle of mouth in the valve of the gas tank of airbag aeration, and a transverse direction is led to Stomata, the pressure at the two ends of each passage is identical, therefore no matter gas tank outside has much with internal pressure, does not affect bullet Spring ejects mouth in valve.Valve jacket internal has an annular groove in the position of passage to mouth ventilation in compensation flap The air pressure on hole periphery, facilitates the axial movement of mouth in valve.Have lubricating grease between mouth in valve overcoat and valve, play lubrication and Sealing function, it is beneficial that when shipwreck and wrecking submarine salvaging are carried out with the gas bag, the ship sued and laboured is without very big, personnel Without a lot, it can reach that canoe rescues the effect of big ship.
(Four)Brief description of the drawings
Accompanying drawing for the present invention can in water automatic inflating airbag structure schematic diagram.
Wherein:Mouth in 1 cylinder package, 2 springs, 3 valves, 4 reinforcing sleeves, 5 valve overcoats, 6 locating slots, 7 jackscrews, 8 sealings Circle, 9 swivel nuts, 10 air bags.
(Five)Embodiment
As shown in drawings for the present invention can in water the air bag of automatic inflating a kind of specific embodiment.Including:Outside gas cylinder Mouth 3 in shell 1, spring 2, valve, reinforcing sleeve 4, valve overcoat 5, locating slot 6, jackscrew 7, sealing ring 8, swivel nut 9 and air bag 10.
Wherein cylinder package 1 is welded with steel plate, and one reinforcing sleeve of welding at the valve of dress input and output gas 4, deflation valve mouth 3 in valve overcoat 5 and valve is constituted, and the outermost end of valve overcoat 5 has screw thread to be used for connecting air bag 10. It is state of the gas cylinder internal full of gases at high pressure and the unaerated of air bag 10 shown in accompanying drawing, now the inside of locating slot 6 is whole full of one Block eats the free of contamination solid that rock sugar or other chance water can dissolve, and outside is sealed with paraffin, and locating slot 6 is drum-shaped, Jackscrew 7 is tight condition, before gas bag and the implementation salvage operation under water of gas cylinder input, according to gas cylinder institute submerged Depth, a sizeable aperture is disclosed out by the paraffin envelope of the outside of locating slot 6, then jackscrew 7 is unclamped and screwed down, and then will Gas cylinder and the air bag 10 linked together are put into water together, and now the rock sugar in locating slot 6 can be slowly dissolved into water, most Afterwards, spring 2 promotes the passage that mouth 3 is displaced outwardly in L, valve on mouth 3 and valve overcoat 5 in valve to communicate, in gas cylinder Gases at high pressure spray and inflated to air bag 10 automatically, deploy after the airbag aeration folded of packing.
The invention air bag can multiple Reusability, when being inflated into empty gas cylinder, process on the contrary, first jackscrew 7 is tightened, Unclamp jackscrew 7 after the completion of being inflated into gas cylinder, then by mouth in valve 3 to the inside jacking apart from L length, jackscrew 7 is tightened, and to fixed The edible rock sugar that injection heating melts in the groove 6 of position, outside is sealed with paraffin after cooling.
It is able to can also be welded together with threaded connection between reinforcing sleeve 4 and valve overcoat 5.
Gas cylinder is connected together with air bag 10 by swivel nut 9, and intermediate cryptographic seal 8 is sealed, and prevents gas leakage.
