Background

At the water inlet of the pump station, in order to prevent floating objects from interfering with the operation of the pump station, a trash holding device must be arranged. When a large-scale pump station pumps water, the water diversion flow velocity is very high, particularly in the flood season or the water supply peak period, the water diversion channel meets a large amount of floating objects such as dead branches, and if the trash blocking and the trash cleaning are not timely, the empty load operation of the pump station is caused, and the safety of the pump station is threatened.

In order to solve the problem, an automatic trash cleaning device such as a grab bucket or a conveyor belt is generally adopted, but the above mode is not suitable for blocking and cleaning trash at a high flow rate. In the existing patent technologies, for example, the patent technology with the application number of CN 110886278A (published 2020.03.17), a grab bucket is adopted for cleaning, which is easily supported by branches and the like, thus hindering the operation of the cleaning device and having low cleaning efficiency; for example, in the patent technology of CN111287148A (published japanese 2020.06.16), the collection device is easily blocked when the amount of floating objects is large by adopting lateral interception and trash blocking and transporting the floating objects to the collection device, so that the fault tolerance is low.
