specific Embodiment approach 1

[0007] Specific Embodiment 1: This embodiment is described in conjunction with 1. An active balance cabin for internal and external pressure in this embodiment includes a cabin body 1, a controller 2, a solenoid valve 3, a high-pressure gas cylinder 4 and a sensor 5, a controller 2, and a solenoid valve. 3 and the sensor 5 are arranged in the cabin body 1, the electromagnetic valve 3 and the sensor 5 are respectively connected with the controller 2, and the high-pressure gas cylinder 4 is arranged outside the cabin body 1 and communicated with the inner cavity of the cabin body 1 through an air circuit.

[0008] When the present invention is actually used, different sensors are selected according to different marine environments, and the sensors can be flexibly adjusted and placed.

[0009] The built-in software of the controller 2 of the present invention can realize the acquisition of pressure information inside and outside the cabin by the sensor, and through certain algorit...

specific Embodiment approach 2

[0012] Specific implementation mode two: combination figure 1 Describe this embodiment, the balance cabin of this embodiment also includes a motor 6, the motor 6 is arranged in the cabin body 1, and the output shaft of the motor 6 is connected with the side wall of the cabin body 1 in a dynamic seal. In this way, when the internal and external pressure active balancing cabin equipped with a motor is used underwater, since the pressure in the cabin is actively balanced with the external water environment through the control method as described in Embodiment 1, the output shaft of the motor is connected to the water environment. The dynamic sealing of the side wall of the cabin can meet the water-retaining requirements; and the traditional underwater motor, the pressure inside the airtight casing and the external environment is not balanced in real time, and the dynamic sealing performance is very high. Therefore, the cost can be reduced by adopting the method of the present inv...

specific Embodiment approach 3

[0013] Specific implementation mode three: combination figure 1 The present embodiment will be described. The sensor 5 of the present embodiment is a pressure sensor, a liquid level sensor, or a displacement sensor. With such a setting, it is convenient to select different sensors according to different application environments. Other compositions and connections are the same as those in the second embodiment.

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. Contents of the invention [0003]...
