AI Technical Summary

Technical Problem

The installation and service life of electric actuators for underground valves are affected by space constraints and humid environments, and existing technologies are unable to effectively solve this problem.

Method used

An extended drive device for an electric actuator was designed. The power of the ground electric drive equipment is transmitted to the control rod of the underground valve through a drive rod, universal joint, transmission rod and power output rod. The connection is protected by a protective top cover and positioning ring to prevent corrosion, and the connection stability is improved by magnetic adsorption ring and contact ring.

Benefits of technology

It enables the installation and use of electric drives in situations where underground space is limited, protects electric drive equipment from humid environments, extends service life, and facilitates quick installation and disassembly.

Abstract

The utility model relates to the technical field of extension driving equipment, in particular to an extension driving device of an electric driver, which comprises a driving rod connected to ground driving equipment and a control rod connected to an underground valve, and the bottom end of the driving rod is connected with a transmission rod through a universal joint. The end, away from the driving rod, of the transmission rod extends into the ground and is connected with a power output rod through a universal joint, and the bottom of the power output rod and the top of the control rod are fixedly installed. By means of the driving rod, the universal joint, the transmission rod and the power output rod, power of ground electrically-driven equipment can be transmitted to a control rod of an underground pipeline valve, extended driving of the electric driver is achieved, and the electric driver can be conveniently used in the underground space which is too small and can be used for driving the underground pipeline valve. And meanwhile, the overground electric driving equipment can be better protected, and the situation that the service life of the electric driver is affected by the underground humid environment is avoided.
