Anti-blocking intercepting well capable of controlling water speed

Abstract

The invention discloses an anti-blocking intercepting well capable of controlling water speed. The anti-blocking intercepting well comprises a well body. A driving motor is embedded in the left side of the well body, and an output end of the driving motor is fixedly connected with a driving rod. The other end of the driving rod is rotatably connected with the right inner wall of the well body. Position changing tools are fixedly installed on the surface of the driving rod, and the lengths of the position changing tools located above the driving rod are different from the lengths of the position changing tools located below the driving rod. According to the anti-blocking intercepting well capable of controlling the water speed, the driving motor drives the driving rod to rotate, the drivingrod drives the position changing tools to rotate, when protruding homopolar magnetic pieces at the ends of the position changing tools rotate to the highest position, the distances between the protruding homopolar magnetic pieces and sliding position homopolar magnetic pieces are relatively shortest, under the repulsive force effects of the protruding homopolar magnetic pieces and the sliding position homopolar magnetic pieces, the sliding position homopolar magnetic pieces slide upwards in sliding grooves, so that the sliding position homopolar magnetic pieces pull a high-elasticity memory plastic filter layer, the high-elasticity memory plastic filter layer is stretched in a telescopic groove, the hole diameter of the high-elasticity memory plastic filter layer is increased, and therefore the permeation effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of interception wells, in particular to an anti-clogging interception well with controllable water velocity. Background technique [0002] In my country's urban drainage projects, interception wells are used in rainwater and sewage confluence systems for the purpose of separating rainwater and sewage. In the dry season, there is only sewage in the pipe. The interception well can intercept the sewage and flow into the sewage pipe. In the rainy season, part of the rainwater and sewage are intercepted and flow into the sewage pipe. The rest of the rainwater overflows through the weir in the well and continues to flow downstream. [0003] For the urban drainage system, the initial rainwater that exceeds the interception capacity of the main drainage pipe is directly discharged into the natural water body. Since the initial rainwater carries a large amount of floating and suspended matter, when the initial rainwa...

AI Technical Summary

Problems solved by technology

In the prior art, interception wells are usually used to intercept floating and suspended solids. However, when most of the existing interception wells operate continuously for a long time, debris will accumulate at the junction between the inner wall of the interception well and the overflow weir, causing blockage.
