If it is not cleaned in time, the submersible sewage pump is prone to blockage and damage when discharging sewage.

[0004] In the prior art, the utility model with the authorization announcement number CN206957938U is named: a suspended submersible sewage pump. The device proposed in the patent document installs floating rings at both ends of the crossbar, so that the submersible sewage pump can float on the water surface to prevent the sewage pump from being blocked, and the pumping position of the sewage pump can be controlled at any time. It is stable and reliable, and has a simple structure, convenient operation, and is economical and practical.

[0005] In the prior art, the utility model with the authorization announcement number CN213360442U is named: a suspended submersible sewage pump. The device proposed in the patent document is provided with a rotatable rotating rod at the right end of the pump body, and the right end of the rotating rod is connected with a twisting rod.
