Compensation-bag battery box for deep submergence vehicle

Abstract

The invention provides a compensation-bag battery box for a deep submergence vehicle. The battery box comprises a box body, wherein the box body is provided with an oil charge valve and a water-tight socket respectively; a compensation bag is hermetically arranged on the port of the box body by means of a connecting piece; the top end of the compensation bag is provided with a one-way valve; pressure compensation oil is injected below the compensation bag; a storage battery is arranged in the box body; and an external pressure on the battery box is counteracted by the volume reduction of compensation oil and the increase of an internal pressure to realize pressure compensation. Accessories, such as an external compensator and a compensation oil pipe are eliminated, so the problem of integration of the storage battery with a compensation structure is solved, the design is simplified, a storage battery box body is convenient to arrange and the entire size and weight of the battery box are reduced.

Description

technical field [0001] The invention relates to a pressure compensation device for operating equipment in a deep-sea pressure environment. In particular, the utility model relates to a pressure compensating box for placing storage battery packs in various deep-sea submersibles. Background technique [0002] When the deep submersible works in a deep-sea pressure environment, its power supply - many battery packs must be connected in parallel or in series. These parallel or series battery packs need to be placed in a pressure compensation box, and the deep-sea pressure received by the battery pack should be adjusted. Compensation or elimination, so as to ensure the normal operation of the battery pack in the deep submersible. In the prior art, external pressure compensators are generally adopted for these battery packs to compensate or eliminate the deep-sea pressure that the battery packs are subject to, such as the Russian Mir and Japan's Deep Sea No. 6500 manned submersibl...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems of complex structure, large volume, heavy weight, poor integrity and troublesome installation, the battery power supply equipment in existing deep submersibles usually uses an external pressure compensator to compensate or eliminate the deep sea pressure on the battery pack. Improvements have been made to provide a compensation bladder-type battery box for deep submersibles, which is used as a power source for deep submersibles—the pressure compensation device for the battery pack. The pressure compensation box and the battery pack are integrated, which has good integrity and simple structure. , Small size, light weight, easy installation, etc.
