Description

Technical Field

[0001] The utility model relates to the technical field of water inlet pools of pumping stations, and in particular to a combined flow guiding device for improving the flow state of a water inlet pool of a lateral water inlet pumping station. Background Art

[0002] The pump station inlet pool is the pool where the pump station directly pumps water through the inlet pipe. To ensure the healthy operation of the pump station, the water in the inlet pool needs to have a smooth and stable flow.

[0003] A connecting section is usually set between the traditional water inlet pool and the water diversion channel, which is the forepool. The water in the water diversion channel gradually smoothes out during the process of diffusing from the forepool to the water inlet pool, creating good water inlet conditions for the water pump. At the same time, it also has the function of regulating the water level in the pool. Generally, the layout of the forepool and the water inlet pool mostly adopts forward water inlet. However, when the terrain conditions are special and forward water inlet is difficult to arrange, there is a situation where the water inlet pool is directly arranged on the side of the water diversion channel.

[0004] However, the side water inlet pool does not have a positive water inlet direction, and the water inlet direction is at a certain angle, resulting in uneven distribution of the flow state. At the same time, it will be accompanied by large-scale swirls, deviation of the mainstream, deflection, vortexes and other phenomena. These unfavorable flow states will have an adverse effect on the water pump. Utility Model Content

[0038] The side wall of the water diversion channel 20 is provided with a lateral water inlet pool 10 extending outward;

[0039] A plurality of guide columns 30 are arranged at the connection between the lateral water inlet pool 10 and the water diversion channel 20;

[0042] The water-facing end of the guide plate 40 is configured in a triangular shape.

[0043] When the water in the water diversion channel 20 flows into the lateral water inlet pool 10, the water flow is divided by the water-facing end of the guide plate 40, and the flow state is improved under the action of the guide column 30 to enter the lateral water inlet pool 10, and then smoothly converges to the end of the lateral water inlet pool 10; in this process, the direction of the water flow is guided, the flow velocity is reduced, and the deviation, folding, vortex and other adverse flow phenomena of the mainstream are greatly reduced, which effectively avoids the adverse flow state from entering the lateral water inlet pool 10 and greatly reduces the damage to the water pump.
