Drainage inspection well lid convenient to open

Abstract

The invention discloses a drainage inspection well lid convenient to open, and relates to the technical field of municipal well lids. The drainage inspection well lid comprises a well lid base and a well lid body, an open hole is formed in the well lid body, and a lifting cover plate is fixedly connected into the open hole; a first circular ring is fixedly connected to the position, located at theopen hole, of the lower surface of the well lid body, a second bearing ring used for supporting the cover plate is fixedly connected into the first circular ring, a plurality of clamping holes are formed in the second bearing ring, a supporting disc is fixedly connected into the first circular ring, and an elastic structure used for assisting in opening the cover plate is fixedly connected to thesupporting disc; a through hole is formed in the center of the cover plate, a second circular ring is fixedly connected to the lower surface of the cover plate, and clamping blocks matched with the clamping holes are arranged on the peripheral side face of a second drainage hole. The cover plate is connected to the well lid body, the cover plate is rotated to enable the clamping blocks to be located in the clamping holes, the elastic structure can automatically bounce the cover plate, rainwater is drained into a sewer from the peripheral side face of the cover plate, and thus the drainage purpose is achieved.

Description

technical field [0001] The invention belongs to the technical field of municipal manhole covers, in particular to an easy-to-open drainage manhole cover. Background technique [0002] Manhole covers are used to cover roads or deep wells at home to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. They are generally round and can be used for green belts, sidewalks, motorways, and docks. , alleys, etc. At present, most of the manhole covers used in municipal engineering are used to drain water from the roads and avoid rainwater from flooding the roads, thereby affecting traffic and pedestrians. Sewer manhole covers are used to cover the sewers and prevent people or objects from falling. Due to incomplete consideration of drainage design in urban construction and abnormal climate changes in recent years, some cities often suffer from sev...
