As shown in Figure 1 and Figure 2, an integrated pump gate device has a working gate 1, a shaft 2 and a vertical submersible pump 3, the vertical submersible pump 3 is a submersible pump with a large flow rate and low lift, and the shaft 2 is made of steel , the wellbore 2 is set on the working gate 1, the wellbore 2 is a vertical three-way structure, the vertical submersible pump 3 is set in the wellbore 2, the guide vane body 3-1 on the vertical submersible pump 3 and the pump in the wellbore 2 The base 2-1 is placed in cooperation with the cone surface, and the vertical submersible pump 3 is automatically positioned in the shaft 2 by its own weight.

Wherein, the angle at which the guide vane body 3-1 cooperates with the conical surface of the pump placement base 2-1 is 60°. An O-ring 3-3 is arranged at the joint between the guide vane body 3-1 and the conical surface of the pump base 2-1 to prevent leakage. The bottom of the vertical submersible pump 3 has an elbow-shaped water inlet flow channel 3-2, which guides the water flow to enter the pump suction port of the vertical submersible pump 3 evenly, optimizes the suction flow pattern of the pump water inlet of the vertical submersible pump 3, and improves the vertical flow rate. The working environment of the type submersible pump 3 fully exerts the working efficiency of the gate station.
