Description
Technical field
The present invention relates to underwater resistance to piezoelectric batteries, especially a kind of to be suitable for pressure release, the exhaust dress that underwater resistance to piezoelectric battery uses
It sets.
Background technology
With the needs that submersible explores marine resources, the depth of submersible work is more and more deeper, and battery used needs
Deep sea hydraulic directly is born, compares energy to reduce the promotion of battery structure part weight.Zinc-silver oxide cell because with it is higher than energy and
Safety, the underwater pressure-bearing power supply mainly used as countries in the world always.The needs of gassing when zinc-silver oxide cell is because of charge and discharge lead to
It is often open structure design, realizes two functions：1. shell is discharged in the gas of precipitation in time by exhaust apparatus；2. pressing
By the insulating oil inside and outside pressure relief device turn-on battery shell when power changes, shell internal and external pressure balance is realized.But due to zinc-silver
Battery uses alkaline electrolyte, the gas that when repeated charge is discharged that can carry a large amount of lye and enter insulating oil, to reduce
The insulation performance of battery pack, it is therefore desirable to the lye amount gone out entrained by discharge gas when stringent control charge and discharge.
Invention content
The purpose of the present invention is a kind of resistance to piezoelectric battery pressure release reasonable for structure, using effect is good of design, exhaust apparatus.
The technical scheme is that a kind of resistance to piezoelectric battery pressure release, exhaust apparatus, it includes shell, it is characterised in that：
Bottom of device is connect by screw thread with battery case cap, and center is equipped with siphunculus, and interior gas chamber, interior gas chamber are equipped in the top of siphunculus
There are gaps between bottom and the inside bottom of shell, are equipped with gas outlet at the top of interior gas chamber, the outer circumference of gas outlet is set
There is annular retaining ring, louver(-vre) is provided on annular retaining ring, is equipped with outer cover gas chamber in the outside of annular retaining ring, outer cover gas chamber lower part is spacious
Mouthful, porous isolation board and upper porous isolation board in the case where the top of outer cover gas chamber is equipped with successively, the porous isolation board and upper porous under
Absorbed layer is equipped between isolation board.
Absorbed layer described further is degreasing cotton layer.
The part that siphunculus described further is contacted with housing bottom is equipped with sealing ring.
The beneficial effects of the invention are as follows：
The present invention realizes outside two functions of pressure balance and exhaust of underwater resistance to piezoelectric battery, and especially realizing can be effective
It prevents lye from entering battery case with bubble, avoids the decline of battery insulation performance.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
Embodiment is described in detail in conjunction with the figures above：
A kind of resistance to piezoelectric battery pressure release, exhaust apparatus, it includes shell 1, and housing bottom center is equipped with siphunculus 7, outside siphunculus
Side is equipped with screw thread, is used for connecting with battery case cap, and the corresponding housing bottom of siphunculus is equipped with through-hole 6, is equipped in the top of through-hole interior
Gas chamber 2, there are gaps between interior gas chamber bottom and the inside bottom of shell, and gas outlet 12, outlet are equipped at the top of interior gas chamber
The outer circumference of mouth is equipped with annular retaining ring 10, and louver(-vre) 9 is provided on annular retaining ring, is passed through convenient for gas, while being also to gas
Body forms further filtering, is equipped with outer cover gas chamber 3 in the outside of annular retaining ring, outer cover gas chamber lower part is open, in outer cover gas chamber
Top be equipped with down porous isolation board 4 and upper porous isolation board 5 successively, set between porous isolation board and upper porous isolation board under
There is absorbed layer 11；Absorbed layer described in the present embodiment is degreasing cotton layer；The part that bolt siphunculus is contacted with housing bottom is equipped with close
Seal 8.
The present invention is mounted in the implementation of port on battery case top, when battery works under deep sea pressure, may be implemented
Two functions of pressure release and exhaust, moreover it is possible to while electrolyte being avoided to leak with a large amount of carryings of bubble：Pass through what is designed in the device
Air chamber structure, the lower part of the housing space other than the inner and outer gas chamber of interior gas chamber have been each filled with insulating oil, and the present invention is in interior gas chamber
Lower bottom part forms the air-liquid interface of gas and insulating oil, to allow the bubble formed in the electrolytic solution to demarcate by air-liquid
It is ruptured when face, so that the electrolyte that bubble chamber film carries is formed small electrolyte drop in bubbles burst and return again under gravity
It flows in battery case（The density of electrolyte is more than insulating oil）, while allowing the gas that the bubble of rupture carries in outer cover gas chamber
The discharge of oil film bubble is regenerated in the insulating oil of bottom, by entering in the insulating oil of Battery case after upper and lower porous barrier,
The invention avoids electrolyte to be carried out, ensure that insulation performance when Silver-zinc battery uses；Suction is utilized simultaneously
Receive layer come to finally by gas carry out final filtration, guarantee do not have electrolyte leakage.
The above embodiments are merely examples for clarifying the description, and does not limit the embodiments.For institute
For the those of ordinary skill in category field, other various forms of variations or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments, and obvious variation extended from this or change
It moves within still in the protection domain of the invention.
