Electric actuating mechanism capable of preventing lightning surge

Abstract

The invention discloses an electric actuating mechanism capable of preventing lightning surge. The mechanism comprises a cover plate, a groove is formed in the top of the cover plate; an indicator ismounted in the groove; the groove is connected with an indicator in a clamping manner; a gasket is arranged at the top of the indicator; the indicator is tightly attached to the gasket; a frame is arranged at the top of the cover plate; a fixing groove is formed in the top of the frame, a first transverse groove is formed in one side of the outer wall of the frame, a bolt is installed in the firsttransverse groove, a connecting pipe is arranged at the bottom of the indicator, the indicator is connected with the connecting pipe in a hot melting mode, a limiting block is arranged at the bottomof the connecting pipe, and the connecting pipe is connected with the limiting block in a hot melting mode. A protection pad is arranged at the bottom of the indicator of the device, meanwhile, the whole device is detachable, a user can disassemble and maintain parts in the device conveniently, meanwhile, the multiple gas discharge tubes are arranged, high voltage can be effectively converted intolow voltage, the device is effectively protected, and internal parts are prevented from being damaged by high voltage.

Description

technical field [0001] The invention relates to the technical field of electric actuators, in particular to an electric actuator for lightning surge protection. Background technique [0002] An electric actuator is a drive device that can provide linear or rotary motion. It uses some kind of driving energy and works under the action of a certain control signal. The actuator uses liquid, gas, electricity or other energy sources and passes through motors, cylinders or other The device converts this into drive action. [0003] However, the existing electric actuator is troublesome to disassemble and assemble the device during use, which leads to cumbersome disassembly and assembly process when repairing internal parts. At the same time, it does not have a gas discharge tube, which causes the internal parts to be easily damaged when the device encounters a lightning surge, and The heat dissipation function of the motor is poor, which leads to troublesome replacement and mainten...
