[0003] Intelligent intercepting wells can automatically adjust the position of intercepting doors or valves according to the flow and water level changes of rainwater to prevent the overloading operation of the drainage system or the occurrence of poor drainage.

[0004] In intelligent intercepting wells, the weir gate devices commonly used mainly include hydraulic flow limiting valves, flexible intercepting devices, flap weirs and hydraulic under-opening weirs, which usually have the functions of flow regulation and water level control. By adjusting the opening degree of the weir gate, the flow and speed of the flood can also be controlled to reduce the impact of the flood on the downstream area.

[0005] These weir gates are usually used during the rainy season. As the flow gradually increases during the rainy season, the sediment deposited in the pipeline will be washed downstream with the rainwater, part of which will be intercepted with the initial rainwater to the sewage pipe network or initial rainwater storage facilities, and the other part will be discharged into the receiving water body with the middle and late rainwater, causing pollution to the water environment.

[0006] For the above problems, the current market's intercepting shield can intercept and flush the rainwater pipeline, gradually washing the sediment deposited in the pipeline to the downstream, and then removing the sediment deposited in the pipeline through the suction vehicle and other treatment measures to solve the overflow pollution of the pipeline network during the rainy season.

[0007] However, for the above-mentioned devices, the weir gate can only control the interception and drainage, and the intercepting shield can only flush along the pipeline. If they are used together, they can solve part of the overflow pollution problem. INVENTION CONTENTS
