Abstract
本发明设计出一种能在水中自动充气的气囊，包括：气瓶外壳（1），弹簧（2），阀门内嘴（3），加强套（4），阀门外套（5），定位槽（6），顶丝（7），密封圈（8），螺套（9）和气囊（10）。气瓶内部充满高压气体时，定位槽（6）内部充满一整块食用冰糖，外面用石蜡封住，顶丝（7）是拧紧的，在气瓶投入水中实施充气作业之前，根据沉入水中的深度，将定位槽（6）外面的石蜡封捅开一个小孔，再将顶丝拧下来，然后将气瓶和气囊投入水中，等定位槽（6）内的冰糖溶解到水中之后，弹簧（2）推动阀门内嘴（3）向外移动距离L，阀门内嘴（3）和阀门外套（5）上的通气孔相通，气瓶内的高压气体自动喷出充满气囊。
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 outer cover (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 wire, 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 shell of the valve (5), and the high-pressure gas in the gas cylinder is automatically ejected to fill the air bag.
Description
（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.
