Automatic flushing device for drainage pipe

Abstract

The invention discloses an automatic flushing device for drainage pipes, which relates to the field of drainage engineering, in particular to a device for preventing siltation of urban drainage pipesand automatically flushing the drainage pipes. The invention mainly comprises a well chamber, a water storage tank, a flow tank, a gate, a locking mechanism, a float and a flow tank, wherein the gateis arranged on the well chamber, the water level of the water storage tank is automatically controlled to open and close by the locking mechanism, and the water of the drainage pipe is used for automatically flushing the pipe. The invention is used for drainage pipes whose longitudinal slopes are limited by the elevation of the connecting pipes, the gradient is small, the flow velocity of the pipes is small, and the sediment in the pipes can be washed automatically with the aid of the water in the drainage pipes, and the water storage and flushing cycle is short, thereby avoiding the sedimentation in the pipes, eliminating the work of dredging the drainage pipes, and saving a large amount of tap water.

Description

technical field [0001] The invention relates to an automatic flushing device for drainage pipes, and relates to the field of drainage engineering, in particular to a device for automatically flushing the drainage pipes for preventing silting of urban drainage pipes. Background technique [0002] Whether it is rainwater or sewage, most of the drainage pipes use gravity flow to discharge from high places to low places. The height difference between the two points of the drainage pipe divided by the horizontal distance between the two points is the longitudinal slope of the pipe. The longitudinal slope is An important parameter in the design of drainage pipelines. It directly affects the flow and velocity of drainage pipelines. If the flow velocity is too small, it will easily cause pipeline siltation. Therefore, the "Code for Design of Outdoor Drainage" GB50014-2006 stipulates the minimum design flow velocity. The sewage pipeline is under the design fullness. 0.6 m / s; rainwate...

AI Technical Summary

Problems solved by technology

Hydraulic dredging adopts high-pressure water jet desilting method. Because of its high efficiency and good dredging quality, it is welcomed by many cities and will gradually replace the original dredging and maintenance tools, but it needs to consume a lot of tap water. The urban water supply is becoming more and more tense, and a large amount of tap water is consumed Flushing pipelines does not meet the needs of sustainable development
