Environment-friendly and energy-saving sewage pump

The invention discloses an environment-friendly and energy-saving sewage pump, belongs to the technical field of sewage pumps, and aims to solve the technical problems that the sewage pump is likely to be damaged due to the fact that the sewage pump vibrates when sucking sundries and topples over underwater, according to the environment-friendly and energy-saving sewage pump, pressure generated by water level rising can press a first extrusion plate, and the first extrusion plate extrudes a pressing plate through an extrusion rod; meanwhile, a first extrusion plate moves downwards to drive a first sealing plate to move, the first sealing plate drives a first fixing block to move, the first fixing block drives a sliding rod to move downwards through a limiting block, and a second fixing block extrudes and pushes a rotating block through a rotating rod; the rotating block pulls out the cleaning plate from the lower portion of the first supporting leg shell through the connecting block, so that when the cleaning
