  • Publication number: 20240159011
    Abstract: An electronic well lid based on electric control travel switch control relates to the technical field of electronic well lids. The electronic well lid based on electric control travel switch control includes a well seat in splined connection with a sliding ring. The sliding ring is provided with a well lid lifting mechanism. A garbage collection mechanism is arranged on the well seat. An arc-shaped groove is formed in the sliding ring. An anti-deviation mechanism is arranged in the arc-shaped groove of the sliding ring. Square grooves are communicated with square holes by way of arrangement of the well lid lifting mechanism and cooperation of first fixing rings and the square grooves. Thus, a drainage speed of the device is increased, pedestrians may continue to pass safely on the well lid in a drainage process of the device, and the protection effect for pedestrians in the drainage process is improved.
