Abstract
The present invention design a kind of can automatic inflating under water airbag, 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 airbag（10）.When gas cylinder internal is full of gases at high pressure, locating slot（6）The internal monoblock that is full of eats crystal sugar, and outside paraffin seals, jackscrew（7）Tighten, before airbag and gas cylinder put into the operation of enforcement inflation under water, according to the depth sinking under the water, by gas cylinder locating slot（6）The paraffin envelope of outside discloses out an aperture, then jackscrew is screwed down, and then puts under water gas cylinder and airbag, waits locating slot（6）After interior crystal sugar is dissolved under water, spring（2）Promote mouth in valve（3）It is displaced outwardly mouth in L, valve（3）With valve overcoat（5）On passage communicate, the gases at high pressure in gas cylinder automatically spray and are full of airbag.
Description
（One）Technical field
The present invention relates to a kind of airbag, especially a kind of structure is simple and convenient to operate, and safe and reliable cost mental retardation is under water
The airbag of automatic inflating, can be widely applied to, in large-scale wreck and the salvage operation of wrecking submarine, belong to maritime affairs salvage technology
Field.
（Two）Background technology
Existing in the world large-scale submarine salvage method mainly has two kinds at present：Floating drum method and lifting method, that is, quite
In the ship with bigger buoyancy or floating drum, submarine is dragged for up from seabed.Both approaches have workload big, and costly, risk is big
Shortcoming with cycle length.
（Three）Content of the invention
The present invention is in order to make up the deficiencies in the prior art, there is provided a kind of structure is simple and convenient to operate, and safe and reliable is big
Airbag is drawn to the cabin of shipwreck and wrecking submarine by the salvage airbag of type shipwreck and wrecking submarine with diving robot during operation
In room or corridor, airbag automatic inflating, the water in cabin or corridor is squeezed away, shipwreck floats.
It is characterized in, to there being an axial passage in the middle of mouth in the valve of the gas tank of air bag inflator, and one laterally leads to
Pore, the pressure at the two ends of each passage is identical, therefore no matter outside gas tank and internal pressure has much, does not affect bullet
Mouth in valve is ejected by spring.Valve jacket internal has an annular groove to ventilate in order to mouth in compensation flap in the position of passage
The air pressure of hole periphery, facilitates the axial movement of mouth in valve.Have grease between mouth in valve overcoat and valve, play lubrication and
Sealing function is it is beneficial that when carrying out shipwreck and wrecking submarine salvaging with this airbag, the ship sued and laboured is without very big, personnel
Without a lot, the effect that big ship rescued by canoe can be reached.
（Four）Brief description
Accompanying drawing for the present invention can automatic inflating under water air bag structure schematic diagram.
Wherein：1 cylinder package, 2 springs, mouth in 3 valves, 4 reinforcing sleeves, 5 valve overcoats, 6 locating slots, 7 jackscrews, 8 sealings
Circle, 9 swivel nuts, 10 airbags.
（Five）Specific embodiment
As shown in drawings for the present invention can the airbag of automatic inflating under water a kind of specific embodiment.Including：Outside gas cylinder
Shell（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 airbag（10）.
Wherein cylinder package（1）It is welded with steel plate, and one reinforcement of welding at the valve of dress input and output gas
Set（4）
Venting valve is by valve overcoat（5）With mouth in valve（3）Composition, valve overcoat（5）Outermost end have screw thread use
To connect airbag（10）.It is that gas cylinder internal is full of gases at high pressure and airbag shown in accompanying drawing（10）The state of unaerated, now fixed
Position groove（6）It is internal that full of the edible crystal sugar of a monoblock or other free of contamination solid meeting water energy dissolving, outside paraffin seals,
Locating slot（6）It is drum-shaped, jackscrew（7）Tight condition, airbag and gas cylinder are put into implement under water salvage operation it
Before, the depth that sunk under the water according to gas cylinder, by locating slot（6）The paraffin envelope of outside discloses out a sizeable aperture, then
By jackscrew（7）Unclamp and screw down, then by gas cylinder and the airbag linking together（10）Put under water together, now locating slot
（6）Interior crystal sugar can be slowly dissolved under water, finally, spring（2）Promote mouth in valve（3）It is displaced outwardly in L, valve
Mouth（3）With valve overcoat（5）On passage communicate, the gases at high pressure in gas cylinder spray automatically to airbag（10）Inflation, packing
Launch after the air bag inflator folding.
This invention can under water automatic inflating airbag can multiple Reusability, when inflating into empty gas cylinder, process
On the contrary, first by jackscrew（7）Tighten, after the completion of inflating into gas cylinder, unclamp jackscrew（7）, then by mouth in valve（3）To the inside jacking
Apart from L length, by jackscrew（7）Tighten, and to locating slot（6）The edible crystal sugar that interior injection heating melts, outside paraffin after cooling
Seal.
Reinforcing sleeve（4）Overcoat with venting valve（5）Between can be with threaded it is also possible to welded together.
Gas cylinder and airbag（10）By swivel nut（9）Connect together, intermediate cryptographic seal（8）Sealing, prevents gas leakage.
