Efficient integrated prefabricated drainage pumping station and drainage method thereof

Abstract

The efficient integrated prefabricated drainage pumping station comprises a well body and a well lid, a water storage cavity is formed in the lower portion of the well body, a water inlet pipe is arranged on the side wall of the water storage cavity, a lower drainage pump is arranged at the bottom of the water storage cavity and connected with a drainage pipe, and a supporting platform with a water passing hole is arranged at the top of the water storage cavity. A floating water pump cabin is arranged on the supporting platform, and an upper drainage pump is installed on the floating water pump cabin and connected with a drainage pipe through a hose. The upper drainage pump and the lower drainage pump are arranged at different heights, so that the number of the water pumps is increased while the occupied area of the pump station is not increased. When the water inflow is large and the water level is high, the floating water pump cabin moves upwards due to buoyancy, the volume of the water storage cavity is increased, the volume of the pump station is adjustable, and therefore the flood storage capacity is enhanced. As known, the water pressure is higher, the water pump drainage speed is higher, the gravity of the floating water pump cabin can increase the water pressure, and therefore the drainage speed of the drainage pump is increased.

Description

technical field [0001] The invention relates to the field of pumping stations, in particular to a high-efficiency integrated prefabricated drainage pumping station and a drainage method thereof. Background technique [0002] Some pumping stations are affected by various factors and cannot occupy too much area. For example, the drainage pumping station passing through the tunnel must be set in a limited area, which results in a small volume of the pumping station and a weak water storage capacity. , Due to the limited floor space and limited space in the pumping station, generally only one drainage pump can be installed. When the rainfall is large and the water is collected in a short time into the pumping station, the water storage capacity of the pumping station is difficult to meet the requirements. At the same time, the drainage speed of a drainage pump is slow, and the drainage efficiency is not high. [0003] CN208395975U discloses an integrated prefabricated pumping s...

AI Technical Summary

Problems solved by technology

[0002] Affected by various factors, some pumping stations cannot occupy too much area. For example, the drainage pumping station that passes through the tunnel must be installed in a limited area, which results in a smaller volume of the pumping station and a weaker water storage capacity. In addition, , due to the limited area and limited space in the pumping station, generally only one drainage pump can be installed. When the rainfall is large and a large amount of water collects in the pumping station in a short period of time, the water storage capacity of the pumping station cannot meet the requirements. At the same time, the drainage speed of a drainage pump is relatively slow, and the drainage efficiency is not high

[0003] CN208395975U discloses a kind of integrated prefabricated pump station volume self-monitoring adjustment device, the adjustment structure is complex, multiple sensors are used, and the fault tolerance rate is low

CN211143279U discloses an integrated pumping station with variable volume, a cleaning mechanism and a diversion mechanism. Three submersible pumps are arranged side by side in the cylinder, which occupies a large area and is not suitable for special scenarios.
