This utility model relates to the field of hydraulic machinery, specifically to a mechanical pump. A conical filter screen is located at the inlet, providing a large flow area and high interception efficiency, effectively blocking large particles of impurities in the water and preventing them from entering the pump body and causing damage or blockage.

The microcontroller receives data from sensors, makes judgments, and controls an electric ball valve to open for flushing. Furthermore, the water flow from the flushing inlet drives a flushing turbine, which in turn drives a cleaning brush to clean the filter screen. This invention solves the problems of existing mechanical pumps being prone to clogging, requiring manual cleaning after clogging, which increases water flow resistance, reduces pump efficiency, and can even cause shutdowns.
