Method for self-cleaning of bottom of prefabricated pump station
The invention relates to a facility for a water conservancy project, in particular to method for self-cleaning of the bottom of a prefabricated pump station and belongs to the technical field of water conservancy projects and municipal engineering. The method relates to a pump cylinder, a submersible sewage pump, an escalator and a maintenance platform, the submersible sewage pump, the escalator and the maintenance platform are arranged in the pump cylinder, the pump cylinder is formed by connecting a cylinder body and a circular truncated cone-shaped cylinder bottom, the diameter of the upper bottom of the circular truncated cone-shaped cylinder bottom is larger than that of the lower bottom of the circular truncated cone-shaped cylinder bottom, an opening in the upper bottom of the circular truncated cone-shaped cylinder bottom is connected with the cylinder body, a bottom plate is arranged at the lower bottom of the circular truncated cone-shaped cylinder bottom, a silt-preventing cone body is arranged in the central area of the bottom plate of the circular truncated cone-shaped cylinder bottom, the conical surface of the silt-preventing cone body is a concave curved surface, a water inlet pipe is provided with a smashing type grafting, and a water suction hole of the submersible sewage pump is arranged above the silt-preventing cone body. The method has the advantages that the structure is reasonable and simple, manufacturing is easy, and the method is advanced and scientific; by the adoption of the method, the problem that silting easily happens to the bottom of the prefabricated pump station is effectively solved.
