Abstract

The invention discloses an underwater electric actuator, which comprises an electric actuator, a protective barrel body, a first pressure cap, a sealed cabin and a second pressure cap. The electric actuator comprises an electric actuator body and a telescopic rod connected with the electric actuator body; the protective barrel body is arranged on the electric actuator body. The front end of the protective barrel body is hermetically and fixedly connected with the first pressure cap, the rear end of the protective barrel body is hermetically and fixedly connected with the second pressure cap, the sealed cabin is fixedly connected with the second pressure cap, the telescopic rod passes through the second pressure cap and the sealed cabin, and the telescopic rod and the second pressure cap and the telescopic rod and the protective barrel body are sealed and connected; a sponge thin insulating oil filling area, a rubber sleeve and a viscous insulating grease asbestos ring are arranged coaxially from the outside to the inside of the sealed warehouse; the side wall of the sealed cabin is provided with an opening on the side of the sealed cabin, and a third pressure cap is installed at the opening of the sealed cabin. The underwater electric actuator can improve the dynamic sealing performance of the underwater actuator and overcome the defect that the underwater electric actuator iseasy to leak.

Description

technical field [0001] The invention relates to the technical field of marine deepwater engineering, in particular to an underwater electric actuator. Background technique [0002] With the deepening of people's understanding of nature, the importance of the ocean to human life has gradually emerged. The 21st century is the century of ocean development. Underwater electric actuators are generally used in underwater marine engineering to perform functions such as object movement, clamping, grasping, and lifting. Common underwater electric actuators have poor dynamic sealing performance underwater, causing seawater to easily flow into the electric actuator, damaging the electric actuator, and shortening the service life of the underwater electric actuator. Contents of the invention [0003] The object of the present invention is to provide an underwater electric actuator to solve the above-mentioned problems in the prior art, improve the dynamic sealing performance of the u...
