AI Technical Summary
In existing water conservancy and hydropower construction, submersible pumps suck in sewage with high sand content, causing filter screen blockage and pump body wear. The cleaning mechanism fails when there is a lot of dust, and the accumulation of impurities affects drainage efficiency.
A drainage device including a cleaning mechanism and a collection component is designed. The cleaning frame is rotated by the drive component, the cleaning brush cleans the impurities on the surface of the filter screen and collects the impurities into the collection component to avoid the accumulation of impurities.
Effective cleaning of impurities on the surface of the submersible pump filter screen ensures stable operation of the submersible pump and improves drainage efficiency and stability in water conservancy and hydropower construction.
