[0002] With the continuous development of my country's economy and industry, an increasing number of pumping stations are needed to lift and transport water. Pumping stations are hydraulic projects that use pump units and flow channels to transfer and convert energy, achieving water transport to create benefits and avoid harm. The equipment in a pumping station is the core component, and together with other ditches, canals, rivers, and reservoirs (lakes), it forms a pumping station project, enabling the pumping station to perform hydraulic functions such as water lifting for irrigation (water supply), water drainage, and water transfer. With the continuous improvement of urban flood control and drainage standards and irrigation design requirements, integrated pumping stations have been further promoted and applied due to their advantages such as low project investment and easy installation and maintenance.

[0003] Existing integrated pumping stations generally only have a one-way pumping function. However, in new rural areas, large and medium-sized irrigation areas, and urban rivers, there is a dual need for drainage or flood control as well as water diversion, meaning that pumping stations require bidirectional water pumping. Single-way pumping stations designed solely for drainage or diversion are no longer able to meet the dual needs of flood control and diverting water from external rivers for irrigation or to supplement ecological landscape water use.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0022] Combine Figures 1 and 2 It can be seen that a bidirectional integrated pump station includes a pump station shell 1, a wellbore 2 is provided in the pump station shell 1, a submersible pump assembly 3 is provided in the wellbore 2, two sets of flow channels are connected to the wellbore 2, the flow channels include an inlet pipe 4 and an outlet pipe 5, and butterfly valves 6 are provided in the inlet pipe 4 and the outlet pipe 5.

[0023] A first layer plate 7 is horizontally provided inside the pump station shell 1. The first layer plate 7 divides the inner cavity of the pump station shell 1 into an inlet layer 8 and an outlet layer 9. The upper end of the wellbore 2 passes through the first layer plate 7 and the two outlet pipes 5 are both located in the outlet layer 9, and the two inlet pipes 4 are both located in the inlet layer 8.

[0024] The two water outlet pipes 5 are coaxially arranged, and the two water inlet pipes 4 are coaxially arranged, and the water outlet pipe 5 is located above the water inlet pipe 4.

[0025] A second layer 10 is provided inside the pump station housing 1 and above the first layer 7 . An electrical layer 11 and a water outlet layer 9 are located above and below the second layer 10 , respectively. A control cabinet is provided in the electrical layer 11 .

[0026] An exhaust pipe 12 is located at the upper end of the shaft 2, equipped with an exhaust valve. The exhaust valve is connected to a control cabinet for easy electrical control of the exhaust valve. The purpose of the exhaust pipe 12 is to remove air from the pipeline and the shaft of the device out of the pump station, preventing air from accumulating in the system during startup and shutdown, which could cause pipeline deformation. The exhaust valve automatically opens and closes during startup and shutdown based on pipeline pressure.

[0027] A ladder 13 is provided in the pump station shell 1, which is connected to the water outlet layer 9, the water inlet layer 8 and the electrical layer 11 respectively.

[0030] Preferably, the diffusion angle of the guide vane 15 is 15°, which increases the diameter of the motor well structure and facilitates the layout of the motor. At the same time, it can further diffuse the water flow, reduce the water flow velocity, and improve the operating efficiency of the integrated pump station.

[0031] Preferably, the submersible pump assembly 3 uses a wet stator motor as a power source, and the motor can be directly immersed in water. On the one hand, the water flow can cool the motor, and on the other hand, there is no need to consider the sealing structure of the entire pumping device, thereby eliminating the waterproof sealing device structure of the motor of a conventional pump device.

[0032] Lifting lugs 16 are provided on both sides of the pump station housing 1 .

[0033] The water outlet of outlet pipe 5 is provided with clapping door 17. Play the effect of cut-off, in case the outlet water flow flows back into the water pump and introduces water pump reversal.
