Description
Technical field
The present invention relates to a kind of field of batteries, relate in particular to a kind of deep water battery case for deepwater environment.
Background technology
Most of deep sea equipment is all from charged pool, and land battery commonly used can not be directly used in abyssal environment, must encapsulate land battery commonly used.The general mode of the encapsulation of Soft Roll lithium battery group being put into battery case that adopts, when battery case is subjected to seawater pressure at the deep-sea, the battery case inside and outside differential pressure can constantly increase along with sea water advanced increase, therefore battery case must have powerful shell to overcome powerful seawater pressure, otherwise battery case will be caused into water short-circuit fire or blast by the seawater pressure compressive strain.As from the foregoing, the technical problem that battery case will solve, comprise following some: 1, water is to the influence of battery; 2, hydraulic pressure is to the influence of Battery case; 3, isolate the influence that oil volume changes in the casing.Solution commonly used is to add an outermost layer of skin capsule to carry out pressure compensation.But outermost layer of skin capsule self is aging easily, easily comes off, thereby causes the repair rate of battery case higher, and can cause water inlet in the case, causes the battery short circuit blast or burns.
Summary of the invention
The technical problem to be solved in the present invention just is: at the technical problem that prior art exists, provide a kind of safe and effective, long service life, deep water battery case simple in structure.
For solving the problems of the technologies described above, the technical scheme that the present invention proposes is:
A kind of deep water battery case, comprise casing and the battery pack that is positioned at casing, described casing is provided with the cover plate for seal case, described casing is provided with for the pressure balance part of balance inside and outside differential pressure and pressure compensation oil, described pressure balance part be diaphragm and be located at cover plate and casing between, described pressure compensation oil riddles box house.
As a further improvement on the present invention:
Be equipped with the hole slot that several are used for strengthening sealing on the contact-making surface of described casing and/or cover plate and diaphragm.
Described hole slot is positioned at the place, outer ring of installing hole on casing and/or the cover plate.
The contact-making surface of described casing and pressure balance part is provided with the annular groove that a circle is used for strengthening sealing, and described annular groove is identical with the case degree of lip-rounding shape of casing.
Between the inwall and battery pack of described casing, be equipped with between diaphragm and the battery pack battery pack be fixed on tension assembly in the casing.
Described tension assembly is the block rubber group, comprises being positioned at the horizontal block rubber around the battery pack and being positioned at vertical block rubber above the battery pack.
Be provided with nonmetallic division board between described vertical block rubber and the diaphragm.
Described cover plate is provided with for the vent valve of getting rid of air in the casing, and described vent valve one end passes diaphragm and is communicated with casing, and the other end extends in the cover plate extraneous air.
Described casing is provided with for replenishing or the oily import and export of discharge pressure compensation, and described import and export are provided with the valve body that control opens and closes.
Compared with prior art, the invention has the advantages that:
(1) deep water battery case of the present invention, pressure balance part between cover plate and the casing is diaphragm, be full of transformer oil in the casing, the diaphragm deformation area is big, increased the compensation volume, the pressure of deep water passes to transformer oil by diaphragm, thereby makes the casing inside and outside differential pressure reach poised state, has solved the influence of hydraulic pressure to casing;
(2) casing of the present invention is provided with import and export, can add or discharge unnecessary transformer oil, has solved to isolate the oil volume variation in the casing to the influence of casing;
(3) the present invention has further set up vent valve, and the gas in the casing of emptying in time reduces gas compressed influence to casing under deep water;
Be squeezed when (4) pressure balance part of the present invention is installed, diaphragm deformation is absorbed in annular groove and the hole slot, reaches the effect of strengthening end face seal, has solved the influence of hydraulic pressure to Battery case;
(5) deep water battery case of the present invention does not need powerful casing to overcome seawater pressure, and casing thickness is low, and battery can adopt Soft Roll lithium battery or lead-acid battery, has reduced the total weight of deep water battery case, has reduced processing cost yet.
