When the water level difference between the inner and outer rivers is large, the water level of the inner river is lower than that of the outer river, but the water level of the inner river needs to be discharged outward. At this time, because the pressure of the outer river is greater than that of the inner river, it is impossible to drain water by opening the gate. The water pump body 101 is opened by cooperating with the drainage gate flange mounting mechanism 12 to force the inner river water to be discharged. This installation method in which the water pump body 101 and the gate are combined into one greatly improves the flood control and drainage efficiency and saves investment costs.

The vertical support base 151 used during installation not only supports the weight of the water pump body 101, but also filters the debris in the transported medium, prevents external debris from entering the water pump body 101, and reduces the risk of damage to the water pump body 101;

[0049] As described above, by increasing the number of installation methods of the water pump body 101, the water pump is changed from a traditional single installation to a multi-mode installation that can be switched at will, which greatly improves the overall utilization rate of the water pump. The water pump body 101 can be used in a variety of installation methods, so that the water pump body 101 is suitable for more water supply and drainage conditions, and the water pump body 101 has the characteristics of one pump for multiple uses. The utilization rate of the water pump is greatly improved, and the overall investment of the project is greatly reduced. The water pump body 101 can be moved at any time and can be built into a temporary drainage pumping station, which reduces the labor operation cost. Due to its unique switchable installation method, one pump can be used under multiple conditions, reducing project investment, and greatly reducing the overall cost of the project or enterprise.
