Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that the water level of the water body during the flood season is relatively high. When the water level is higher than the road surface, the water in the water body will be poured back to the road surface along the drainage pipe, the drainage system will not work normally, and water will accumulate on the road surface.

Embodiment Construction

[0050] Attached to the following Figure 1-4 This application will be described in further detail.

[0051] refer to figure 1 , the embodiment of the present application discloses a municipal drainage system, including a rainwater pipeline 1 and a pump station 2 .

[0052] refer to figure 1 , 2 , the upper end opening of the rainwater pipe 1 is located on the ground, so that the rainwater flows into the rainwater pipe 1 under the action of gravity, thereby completing the collection of rainwater; the lower end opening of the rainwater pipe 1 is connected to the water body (river, river, etc.) Discharge into the water body; the pump station 2 has a water inlet 21 and a water outlet 22, the water inlet 21 is connected to the rainwater pipe 1, and the water outlet 22 is connected to the water body. During heavy rainfall, the natural flow of rainwater along the rainwater pipe may not be able to meet the drainage needs. At this time, Pump station 2 can be activated to accelerate...

Abstract

The present application relates to a municipal drainage system, which includes a rainwater pipe, an anti-backflow device and a pumping station. The anti-backflow device includes installation pipes and baffles. The installation pipe is coaxially connected to the lower end of the rainwater pipe, and the installation pipe is sealed with the rainwater pipe, so that the water in the rainwater pipe is discharged into the water body through the installation pipe; the baffle is rotatably connected to the square opening of the installation pipe, and the baffle includes a board and the shaft. The plate body is rectangular and arranged vertically, and the circumferential side walls of the plate body are used to fit the inner circumference of the square opening of the installation pipe. When the water level of the water body rises above the ground, the baffle plate rotates until the circumferential side wall of the plate fits the inner circumference of the square opening of the installation pipe, so as to prevent the water in the water body from pouring back to the ground.

Description

technical field [0001] The present application relates to the field of municipal engineering, in particular to a municipal drainage system. Background technique [0002] Drainage system is an engineering facility system that treats and removes urban sewage and rainwater, and is an integral part of urban public facilities. [0003] Drainage systems usually consist of drainage pipes and sewage treatment plants. In the case of implementing the sewage and rainwater diversion system, the sewage is collected by the drainage pipeline, sent to the sewage treatment, and then discharged into the water body or recycled; after the rainwater is collected by the drainage pipeline, it is discharged into the nearby water body. [0004] In view of the above-mentioned related technologies, the inventor believes that the water level of the water body is relatively high during the flood season. When the water level is higher than the road surface, the water in the water body will be poured bac...
