Description

Technical Field

[0001] This utility model relates to the field of irrigation pumping station technology, specifically to an irrigation pumping station with a mixed arrangement of vertical and horizontal units. Background Technology

[0002] With the advancement of agricultural modernization, the demand for farmland irrigation is constantly increasing, but traditional irrigation pumping stations have obvious limitations. These pumping stations usually use a single type of pump, which can solve irrigation problems to a certain extent, but lacks flexibility under complex and variable irrigation conditions. For example, when faced with situations where high head and low flow coexist with low head and high flow, multiple independent pumping stations are often required, which increases costs and occupies a lot of land resources. At the same time, different crops have different irrigation needs. Plain paddy fields require low head and high flow, which is traditionally achieved using vertical axial flow pumps, while mountain orchards and economic forests require medium head and medium flow, which is traditionally achieved using horizontal mixed flow pumps, further highlighting the adaptability problem of traditional pumping stations.

[0003] Current irrigation pumping station technology suffers from three major drawbacks: First, it is functionally limited, with each pumping station equipped with only one type of pump. If different crops need irrigation in the same area, different types of pumping stations must be built, resulting in redundant investment in equipment. Second, it is space-consuming and costly, requiring separate construction of facilities for two pumping stations, which not only occupies more space but also increases civil construction and subsequent operation and maintenance costs. Third, it wastes resources, with large pumps remaining idle for extended periods during off-peak irrigation seasons, leading to a waste of energy and equipment resources. Therefore, designing an irrigation pumping station that is "small in footprint, fully functional, and adaptable to multiple operating conditions" is key to solving the current problems. Utility Model Content

[0004] The purpose of this utility model is to provide an irrigation pumping station with a mixed arrangement of vertical and horizontal units to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an irrigation pumping station with a mixed arrangement of vertical and horizontal units, comprising a pump house, an inlet forebay, a vertical axial flow pump, and a horizontal mixed flow pump. The pump house has an operating layer and a floor layer from top to bottom. A water pump suction pool is located in the middle of the pump house, and a vertical axial flow pump is installed inside the water pump suction pool. An inlet forebay is located at one end of the water pump suction pool, and a horizontal mixed flow pump is arranged on the other side of the water pump suction pool. The vertical axial flow pump has a fixed water inlet pipe at its bottom. The bottom of the horizontal mixed flow pump is connected to the top of the outlet pipe of the horizontal mixed flow pump, and the outlet pipe of the horizontal mixed flow pump penetrates the outer wall of the pump house. One side of the horizontal mixed flow pump is connected to the bottom of the water inlet pipe of the horizontal mixed flow pump, and the water inlet pipe of the horizontal mixed flow pump penetrates the outer wall of the pump suction tank. The vertical axial flow pump has an outlet pipe in the middle of one side, and the outlet pipe of the vertical axial flow pump penetrates the outer wall of the pump suction tank.

[0006] The beneficial effects of this utility model are as follows: By integrating a vertical axial flow pump, which is suitable for applications with large flow rates but relatively low head, and a horizontal mixed flow pump, which is more suitable for applications with higher head but smaller flow rates, into the same pump house and allowing both to share an intake pool, the effect of "one pump station covering the entire area" can be achieved, effectively avoiding the redundancy problem of traditional multi-pump station construction, and directly saving land and costs. At the same time, with the help of this integrated design, the operating status of the two pumps can be flexibly adjusted according to the unpredictable needs during actual irrigation. While ensuring that irrigation efficiency is adapted to different crops and different working conditions, the optimal economic benefits can be further achieved, and the overall land area required is greatly reduced, perfectly balancing practicality and resource utilization.

[0007] To ensure that water flows smoothly into the suction tank without being blocked:

[0008] The following configuration is further provided: the inlet pool is connected to the pump suction pool, the bottom elevation of the inlet pool is lower than the bottom elevation of the pump suction pool, and the bottom elevation of the pump suction pool is the same as the bottom elevation of the pump house floor.

[0009] By adopting the above technical solution, the water flow is guided smoothly into the water pump suction pool by the elevation difference, which improves the water delivery efficiency and reduces energy loss. At the same time, the water flow velocity slows down in the forepool, which is conducive to the sedimentation of particulate impurities such as silt and debris. In addition, it can ensure that there is sufficient effective water depth in the water pump suction pool, avoid the "cavitation" phenomenon of the water pump, and ensure the continuous and reliable water supply system.

[0010] To ensure the efficiency and stability of the water supply system, a regular internal space should be constructed to ensure uniform water flow and avoid hydraulic dead zones or vortices caused by irregular spatial shapes.

[0011] The water pump suction pool is further configured as follows: the side of the water pump suction pool is a cuboid structure, the side of the water pump suction pool is open, and the other sides of the water pump suction pool are enclosed by concrete walls.

[0012] By adopting the above technical solutions, the cuboid structure can provide a regular internal space, ensuring that the water flow is evenly distributed in the pool. The design with only one side open allows the water flow in the inlet pool to flow smoothly into the suction pool in a fixed direction, preventing external debris from entering the pool from the non-inlet side. The concrete wall enclosure structure on the other sides enhances the overall rigidity and load-bearing capacity of the suction pool.

[0013] To ensure that the vertical axial flow pump can obtain support, reduce vibration during operation, and minimize resistance and energy loss caused by pipeline detours:

[0014] The configuration is further defined as follows: the top of the vertical axial flow pump is installed on the pump room operating floor, and the water inlet pipe of the vertical axial flow pump is connected to the water outlet pipe of the vertical axial flow pump at a 90° angle to each other.

[0015] By adopting the above technical solution, the pump body can be firmly supported by the stable structure of the operating layer of the pump room. The water inlet pipe of the vertical axial flow pump draws water through the water pump suction pool and delivers the water to the water outlet pipe of the vertical axial flow pump after passing through a 90° corner of the facade.

[0016] To provide stable support for horizontal mixed-flow pumps:

[0017] The configuration is further defined as follows: the horizontal mixed-flow pump is installed on the bottom slab of the pump house, and the water inlet pipe of the horizontal mixed-flow pump is connected to the water outlet pipe of the horizontal mixed-flow pump at a 90° angle to each other.

[0018] By adopting the above technical solution, the pump installed on the bottom slab of the pump house can rely on the solid bearing foundation of the bottom slab to provide stable support for the pump body, which greatly reduces the vibration during the operation of the equipment. The water inlet pipe of the horizontal mixed flow pump draws water through the water pump suction pool and delivers the water to the outlet pipe of the horizontal mixed flow pump after a 90° turn in the plane.

[0019] To save space and reduce the overall construction area and engineering cost of the pump house:

[0020] The system is further configured such that the vertical axial flow pump and the horizontal mixed flow pump share the pump house operating floor as a maintenance platform.

[0021] By adopting the above technical solutions, the equipment can be centrally arranged within the limited building area of ​​the pump house, improving space utilization, reducing the overall construction area and engineering cost of the pump house, and facilitating staff to carry out daily inspections, maintenance and troubleshooting on the same operating plane.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description
