Compared with prior art, the beneficial effects of the utility model are:
1, owing to placing the storage tank depositing low pressure liquefied gas in soft air bag, the tank mouth of storage tank is fixed with pressure plate, after black box and subsidiary buoyant device sink to seawater, along with the increase of sinkage, the hydraulic pressure of seawater constantly increases, reach after the rated pressure value sum that storage tank internal pressure and pressure plate can bear until hydraulic pressure, the soft wall pressure of air bag is connected on pressure plate by hydraulic pressure, by pressure, pressure plate is crushed, the low pressure liquefied gas left in storage tank is able to sharply release spatially, by liquid conversion gaseous state, air bag thus inflation swell, suffered buoyancy increases, black box is driven to float up to sea, thus be convenient to find and salvage.
2, owing to being set with the string bag outside soft air bag, only the string bag need be connected with black box during use, facilitate the connection of air bag and black box.
3, owing to being provided with the stainless steel box of the storage string bag and air bag, for the string bag to be provided with air bag together with protective barrier, avoid it damage by External Force Acting, the box wall of simultaneously stainless steel box offers permeable mouth, seawater can be made to pour into be acted on pressure plate by hydraulic pressure in stainless steel box, the lid that stainless steel box mounts cover is ejected when air bag swells, then meet the space requirement of air bag.
4, owing to being filled with fireprotection layer between stainless steel box and the string bag, can fire-proof and thermal-insulation, widen the application conditions of this buoyant device.
5, because pressure plate is arranged on tank mouth by anchor fitting, the fitting operation of pressure plate is convenient to.
6, due to anchor fitting tire tube valve and the pressure form of nut or the form of compressing piece, technology maturation, structure is simple, is convenient to realize.
7, owing to being all provided with seal ring between tire tube valve and the inwall of storage tank and between pressure nut and the outer wall of storage tank, improve the sealing property between tank mouth and pressure plate, avoid the blue gas in tank automatically to leak.
8, because the outer wall of air bag selects the eye-catching color such as red or orange, be convenient to search personnel and find.
