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.
