Abstract

The invention discloses a gas-type road sewer cover, which comprises a first annular shell. The invention utilizes the connecting rod principle and the hydraulic principle, so that the device can realize the functions of free lifting and road surface coverage, and at the same time has the function of controlling the flow of internal and external air and liquid, and the device has a reverse thread rotation distance adjustment control The mechanism can realize the position transformation of the connecting parts, and at the same time, it can also perform the necessary rotation function on the connecting parts, which improves the functionality and practicability. In addition, the device has a bolt-mounted rotating part connecting mechanism, which can connect the fixed plate body and In addition, the device has a piston-sealed medium drive mechanism, which can realize the drive function under the action of air.

Description

technical field [0001] The invention relates to the technical field of road equipment, in particular to a gas-type road sewer cover. Background technique [0002] At present, on urban roads, in order to realize the discharge of accumulated water and the normal operation of the road surface, a sewer well will be set up, and a manhole cover needs to be installed on the top of the sewer well.
