Multilayer filtering gutter inlet device for municipal engineering

Abstract

The invention discloses a multilayer filtering gutter inlet device for municipal engineering. The multilayer filtering gutter inlet device comprises a roadbed, wherein a drainage pipeline is arranged on the lower end surface of the roadbed; a base frame is arranged on the inner side surface of the roadbed; a fixed sleeve is arranged on the inner wall of the base frame; a through hole is formed in the inner side surface of the fixed sleeve; a shaft frame is arranged on the inner side surface of the through hole; a well lid is arranged on one side of the shaft frame; a water inlet hole and a blind hole are formed in the inner side surface of the well lid; a handle is arranged on the inner side surface of the blind hole; a limiting block is arranged on the lower end surface of the handle; a supporting ring is arranged on one side, close to the base frame, of the upper end surface of the drainage pipeline; a sleeve frame is arranged on one side, close to the shaft frame, of the supporting ring; a movable plate is embedded in the inner side surface of the sleeve frame; and a spring is arranged on the outer surface, close to the supporting ring, of the upper end surface of the movable plate. The multilayer filtering gutter inlet device can prevent the well lid from falling, shifting or losing, is convenient for a cleaner to open the well lid, can cover a gutter inlet to prevent odor in the drainage pipeline from overflowing, and is convenient for taking out a net for filtering impurities to pour the impurities.

Description

technical field [0001] The invention relates to the technical field of municipal engineering equipment, in particular to a multi-layer filter rainwater outlet device for municipal engineering. Background technique [0002] During the construction of municipal roads, drainage pipes are often laid under the roadbed, and rainwater outlets are installed on the road surface to make the rainwater on the road flow into the drainage pipes, reduce the water on the road, and facilitate the passage of vehicles and pedestrians. The soil, leaves or gravel nearby will easily enter the rainwater outlet together with the rainwater, and it will easily block the drainage pipe, causing a large amount of sewage to accumulate on the rainwater outlet, causing the road surface to be covered by sewage, which brings certain dangers to pedestrians and vehicles. [0003] In the existing multi-layer filter rainwater outlet device, the well cover is easy to shift under the impact of the water flow, caus...

[0002] During the construction of municipal roads, drainage pipes are often laid under the roadbed, and rainwater outlets are installed on the road surface to make the rainwater on the road flow into the drainage pipes, reduce the water on the road, and facilitate the passage of vehicles and pedestrians. The soil, leaves or gravel nearby will easily enter the rainwater outlet together with the rainwater, and it will easily block the drainage pipe, causing a large amount of sewage to accumulate on the rainwater outlet, causing the road surface to be covered with sewage, which brings certain dangers to pedestrians and vehicles

[0003] In the existing multi-layer filter rainwater outlet device, the well cover is easy to shift under the impact of the water flow, causing the manhole cover to fall or be lost, and it is difficult for the cleaning personnel to open the well cover. Improve the quality of life of the surrounding residents. At the same time, the net for filtering impurities is easily damaged, and it is inconvenient to take out the impurities and pour them out
