Abstract

The invention belongs to the field of municipal sewage systems, and particularly discloses a gear-and-rack type inspection well lid. The gear-and-rack type inspection well lid comprises an inspection well lid body. A plurality of rainwater holes are formed in the inspection well lid body. A sealing cavity is formed in the inspection well lid body. A generator, a storage battery, a lighting lamp and a controller are arranged in the sealing cavity, and the generator, the controller and the lighting lamp are electrically connected with the storage battery. A transparent plate is embedded in the lower portion of the inspection well lid body. The lighting lamp is bonded to the transparent plate. A guide hole communicated with the sealing cavity is formed in the upper portion of the inspection well lid body. A rack is arranged in the guide hole. A rubber gasket for preventing rainwater from entering the sealing cavity is embedded in the guide hole. A gear engaged with the rack is arranged on a rotor shaft of the generator. A convex block is arranged on the lower portion of the rack and provided with a reset piece. One end of the reset piece is fixed to the convex block, and the other end of the reset piece is fixed to the side wall of the sealing cavity. According to the gear-and-rack type inspection well lid, the lighting function can be provided when an inspection well is maintained by maintenance personnel.

Description

technical field [0001] The invention relates to the field of municipal sewage discharge systems, in particular to a rack and pinion inspection well cover. Background technique [0002] The inspection well is mainly made up of the inspection well cover and the inspection well wall. Reinforced concrete manhole covers are cheap, but their structural strength is poor, and it is difficult to withstand the impact of vehicles for a long time. Cast iron manhole covers have a firm structure and can bear large pressure and impact forces. They are widely used and are mostly used on sidewalks or squares. . The wall of the inspection shaft is relatively dark, and lamps are needed for lighting when going down the shaft for maintenance. [0003] Some squares are also equipped with floor lamps, which are convenient for people to walk, improve the safety at night, and increase the ornamental value of the landscape. However, the floor lamps are installed underground, which is difficult to m...
