Inspection well cover with drainage port deposit cleaning function

Abstract

The invention discloses an inspection well cover with a drainage port deposit cleaning function, and relates to the technical field of municipal inspection well covers. The inspection well cover comprises a base and a cover body, the cover body is fixedly installed in the base, a groove body is formed in the cover body, and a groove hole penetrates through the bottom face of the groove body; a reciprocating moving plate is installed in the groove body, and a plurality of water flowing grooves are formed in the moving plate; a rotating column is fixed to the middle of the inner side face of the moving plate and located in the groove hole, and meanwhile the rotating column is sequentially sleeved with a rotating impeller and a floating block from top to bottom; and the rotating impeller is provided with an outer ring body, and an eccentric structure is arranged on the inner side of the outer ring body. A movable plate capable of reciprocating is installed on the cover body, balls arranged in an annular groove are gathered at the eccentric structure of the annular groove under the action of centrifugal force, an eccentric mechanism is formed, the movable plate is driven to reciprocate along the groove body, and therefore accumulated objects on the groove body are pushed to move, and cleaning is convenient to complete.

Description

technical field [0001] The invention belongs to the technical field of municipal inspection well covers, and in particular relates to an inspection well cover with the function of clearing accumulations at drain outlets. Background technique [0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section. Called the inspection well, the inspection well mouth is usually flush with the ground, so a cover is needed to cover the inspection well, which is called the inspection well cover. Manhole covers are usually made of reinforced concrete, metal, reinforced plastics and other materials, and their shapes are based on circles and squares. On the inspection well cover, it is generally necessary to indicate the purpose of the underground pipeline, the managemen...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a manhole cover with the function of clearing the accumulation of drains. A moving plate capable of reciprocating motion is installed on the cover body, and the balls provided in the ring groove gather at the eccentricity of the ring groove under the action of centrifugal force. At the structural part, an eccentric mechanism is formed to drive the moving plate to reciprocate along the tank body, so as to realize the movement of the deposits on the tank body, which is convenient for cleaning, and solves the problem that the existing manhole cover does not have accumulations at the drain outlet during the working process. Ease of cleaning issues
