The utility model relates to a device which can be used for generating buoyancy in underwater salvaging operation, which is characterized in that the utility model comprises a pressure vessel, hydrogen-storing alloy, a heat exchange system and a floating barrel in which a barrier film is arranged, with the functions of hydrogen suction and discharging of the hydrogen-storing alloy, the utility model can cause the floating barrel generating buoyancy or submerging. The utility model can be used for salvaging operation and can omit the long air transmission pipe, so the operation range is free and can not be limited. The utility model can also be used as a lifting and submerging system device of new submarines and has the function of fish bladder.

Description

Equipment using metallic hydride to produce buoyancy

The utility model relates to a kind of device that can be used as the generation buoyancy of underwater salvage operation.

Present known underwater salvage method is to be tied injecting water in the floating drum earlier, sinking under the water and dragged for thing (as shipwreck), with pressurized air the water in the floating drum is discharged then, and the floating drum come-up will be dragged for thing and be emerged.When the major defect of this Refloatation method is to get rid of water in the floating drum, need a very long conveying pressurized air pipe, and provide pressurized air by the ship on the water surface, this just makes that fishing operation scope under water has been subjected to limitation, and floating drum when come-up, the safety of water surface workboat has certain danger.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and a kind of device that can be used as the generation buoyancy of salvaging usefulness of long gas transmission pipe in tow that do not need is provided.The utility model can also play the effect of air bladder as the liter of novel submarines, the system and device of diving.

The utility model is made up of pressure container, hydrogen-storage alloy, floating drum, heat-exchange system, valve, hydrogen compressing pump, barrier film, pipeline etc.Utilization is contained in hydrogen-storage alloy in the pressure container, and (hydrogen-storage alloy is the new function material that grows up in recent decades, having and can inhale the hydrogen and the function of putting hydrogen repeatedly) hydrogen (certain pressure is arranged) that discharges when being heated charges into floating drum, produce buoyancy, to be dragged for object floats, provide pressurized air with regard to need not by the ship on the water surface like this, saved long gas transmission pipe, the underwater action radius of fishing operation no longer is subjected to the constraint of gas transmission pipe.If this covering device is contained on the special-purpose midget submarine, just can seek the sinking object under water, can salvage immediately again after finding, can also design novel submarine liter, latent system with the utility model.

The utility model will be further described below in conjunction with accompanying drawing:

Accompanying drawing structure principle chart of the present utility model

Description of drawings: 1. transport and store the pressure container of hydrogen alloy, 2. hydrogen-storage alloy, 3. floating drum, 4. heat-exchange system, 5,6, valve, 7. the hydrogen compressing pump, 8. barrier film, 9. pipeline, 10. the hydrogen on the floating drum import and export, the pipeline of the import and export .12. radiator of 11. water.

The utility model comprises pressure vessel (1), storage hydrogen alloy (2) valve and heat-exchange system (4), there is the floating drum (3) of one deck barrier film (8) inside, the air inlet of floating drum (10) connects with an end of pipeline (9), the other end of pipeline is divided into two branch pipe(tube)s, a series connection valve (5) on branch pipe(tube) wherein, connecting on another branch pipe(tube) a valve (6) and a hydrogen compression pump (7), two then Pipeline converges a place again, with storage hydrogen pressure container (1) UNICOM. Gilled radiator and storage hydrogen alloy (2) are housed in the pressure vessel (1), the pipeline of radiator (12) by cover switch valve and a water pump both can with submarine in cooling water pipe of engine link, to the heat supply of storage hydrogen alloy, can communicate with outside cold water again, the heat of emitting when dissipating storage hydrogen absorption hydrogen consists of heat-exchange system (4) like this. (11) be the import and export of water on the floating drum.

When pressure vessel (1) heat supply of heat-exchange system (4) to storage hydrogen alloy, storage hydrogen alloy (2) is heated and emits the hydrogen of attracting deposits, open valve (5) hydrogen and enter floating drum (3) through pipeline (9) by hydrogen import and export (10), barrier film (8) is moved downward by the extruding of hydrogen, water in the floating drum is squeezed outside the water inlet outlet expelling tube of water, and therefore floating drum produces buoyancy. In the time will pulling the plug downwards, but valve-off (5) is opened valve (6), and start hydrogen compression pump (7) and heat-exchange system (4) and the hydrogen in the floating drum is imported and exported (10) and pipeline (9) by the hydrogen on the floating drum push back and store hydrogen alloy pressure vessel (1), hydrogen is store hydrogen alloy (2) and is absorbed, and the heat of releasing is simultaneously taken away (heat-exchange system at this moment will switch to the cooling effect position) by heat-exchange system (4). After hydrogen in the floating drum (3) was pumped, negative pressuren zone was formed at the top of barrier film (8), and water will be entered in the floating drum by the import and export (11) of water, and barrier film is upwards pushed away, and the buoyancy of floating drum is decreased in the sinking entry like this. Hydrogen in this covering device is in the closed system, can recycle.

The quantity of the pressure vessel of the storage hydrogen alloy in the utility model can be only (M=1,2,3 of M ... whole), the storage hydrogen alloy that fills in the storage hydrogen pressure container can be hydrogen storage metal and the alloy of any kind, floating drum can be the floating drum of the metal structure of any shape, it also can be the airbag that any fabric adds any coating, its size is not limit, and can manufacture and design by required buoyancy. All controlling elements and mechanism all can adopt manually or automatically control.

The utility model provides the gas of inflating usefulness by hydrogen-storage alloy, but the close cycle use has saved the gas transmission pipe on the existing fishing device, makes the underwater freedom of movement of the utility model, has not been subjected to the restriction of scope, and can be used as the searching object and salvage dual-purpose.

Embodiment: with two total volumes is 0.03M ³Hydrogen storage container, 80 kilograms of rare earth based hydrogen storage alloy are housed, can discharge 12M ³Hydrogen, charge in the airbag that volume is 10M, in water, can produce the buoyancy about 10 tons.
