Urban water supply PE drainage pipe

Abstract

The invention belongs to the technical field of water supply and drainage systems, and particularly relates to an urban water supply PE drainage pipe. The drainage pipe comprises a controller, pipe bodies and a cutting module. The cutting module comprises a gear ring, a motor, a gear and cutting knives. The gear ring is rotationally connected between the two pipe bodies; the inner side of the gear ring is fixedly connected with a group of cutting knives; the surfaces of the pipe bodies are fixedly connected with the motor; a rotating shaft of the motor is fixedly connected with the gear; and the gear ring is an outer gear ring, and the gear is meshed with the gear ring. By arranging the cutting module, garbage such as vegetable leaves, meat residues and waste paper which are not easy to decompose in water is cut into small garbage, so that the garbage is more easily driven by water flow and is not easy to accumulate in the drainage pipe bodies, the drainage pipe bodies of a city is prevented from being blocked, manpower and material resources are saved, and time is saved; and the maintenance cost of a water supply and drainage system is reduced.

Description

technical field [0001] The invention belongs to the technical field of water supply and drainage systems, in particular to a PE drainage pipe for urban water supply. Background technique [0002] Water supply and drainage system is a general term for providing water and wastewater removal facilities for people's life, production, municipal administration and fire protection. [0003] Among them, the urban drainage system is an engineering facility system that treats and discharges urban sewage and rainwater, and is an integral part of urban public facilities. Urban drainage system planning is an integral part of urban overall planning. Urban drainage systems usually consist of drainage pipes and sewage treatment plants. In the case of sewage and rainwater separation system, sewage is collected by drainage pipes, sent to sewage treatment, discharged into water bodies or recycled; rainwater runoff is collected by drainage pipes, and discharged into nearby water bodies.

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies in the prior art, a PE drainage pipe for urban water supply proposed by the present invention solves the problem that in restaurants and people's domestic water, when sewage is discharged, it is often mixed with vegetable leaves, meat dregs and waste paper, etc. Decomposed garbage, these garbage often accumulate in the drainage pipes, which will lead to blockage of urban drainage pipes, and then affect the water supply and drainage system. When cleaning and dredging the drainage pipes, it will take a lot of manpower, material resources and a lot of time.
