Pump station structure with drainage device

The invention discloses a pump station structure with a drainage device, and aims to overcome the defect that a submersible sewage pump is easily impacted by water flow to be damaged due to silt deposition in a prefabricated barrel. A submersible sewage pump is mounted at the bottom of the prefabricated barrel, the upper end of the water inlet pipe is connected to a municipal pipe network, the lower end of the water inlet pipe is connected with a flow dividing head, a plurality of water outlet holes facing the bottom of the prefabricated barrel are formed in the flow dividing head, openings of the water outlet holes deviate from the submersible sewage pump, and the drainage pipe is connected with the submersible sewage pump. According to the pump station structure with the drainage device, inlet water of a municipal pipe network is drained to the bottom of the prefabricated barrel and staggered from the submersible sewage pump, the inlet water is prevented from directly scouring the submersible sewage pump, m
