Internal-and-external-pressure active balancing chamber

Abstract

The invention discloses an internal-and-external-pressure active balancing chamber and relates to a pressure active balancing chamber which is used for creating gas atmospheres in liquid pressure environments. The internal-and-external-pressure active balancing chamber solves the problem of high costs caused by the fact that waterproof structures of existing underwater electrical devices are required to be designed again due to the fact that the waterproof performance does not meet the requirements of deepwater operation. According to the internal-and-external-pressure active balancing chamber, a controller (2), a solenoid valve (3) and a sensor (5) are arranged inside a chamber body (1), the solenoid valve (3) and the sensor (5) are connected with the controller (2) respectively, a high-pressure gas cylinder (4) is arranged outside the chamber body (1) and communicated with an inner cavity of the chamber body (1) through a gas path, an electric motor (6) is arranged inside the chamber body (1), and an output shaft of the electric motor (6) is connected with the side wall of the chamber body (1) in a dynamic sealing mode. The internal-and-external-pressure active balancing chamber has the advantages of being low in cost and capable of enabling devices of different waterproof capabilities to be used at positions of various water depths and is applicable to underwater operation.

Description

technical field [0001] The invention relates to a balance cabin, in particular to a pressure active balance cabin which creates a gas atmosphere in a liquid pressure environment. Background technique [0002] my country is rich in offshore oil resources. With the development of ocean resources, submarine oil pipelines, offshore drilling platforms, and cross-sea bridges have been used more and more. When constructing and maintaining these underwater components, a large number of diving equipment is required, and some electrical equipment such as motors, batteries, etc. need to be specially waterproofed to avoid adverse effects on these equipment caused by the high-pressure water environment. At present, with the increase of operating water depth, the waterproof performance of existing underwater electrical equipment cannot meet the requirements of deep water operations, and the waterproof structure needs to be redesigned, which is costly.
