technical field

The utility model relates to a rainwater inspection well cover mechanism for automatically opening and closing a drainage cover, which belongs to the field of supporting facilities for municipal drainage inspection wells.

Background technique

A rainwater inspection well with a shaft and a well cover is arranged on the main pipe or main pipe of the traditional urban road rainwater pipe at a certain length. Or carry out maintenance and management related operations in the dry pipe. The traditional rainwater inspection well cover is generally a solid airtight structure. Its main function is to cover and seal the rainwater inspection well shaft tightly to prevent the odor in the rainwater pipe from leaking out. The manhole cover is opened only when the rainwater pipe is repaired to allow maintenance personnel or equipment to enter the inspection Well, so the traditional rainwater inspection well cover does not have the function of collecting rainwater on the road. However, in actual operation, especially during heavy rain, in order to reduce or eliminate road surface water, people often open the manhole cover of the rainwater inspection well on the road, so that the rainwater on the road surface can directly flow into the rainwater inspection well and then be drained through the main rainwater pipe or main pipe. In order to increase the ability of the rainwater pipe network system to collect rainwater from the road surface. Therefore, during heavy rains, people have particularly prominent functional requirements for rainwater inspection well covers that can collect road rainwater.
