Sand flushing structure for forebay tree-shaped groove of pump station and design method
The invention discloses a pumping station forebay tree-shaped groove sand flushing structure and a design method. The pumping station forebay tree-shaped groove sand flushing structure mainly comprises a plane and longitudinal diffusion pumping station forebay, a forebay tree-shaped groove and a tail end half-funnel-shaped sand collecting ditch. The diffusion-shaped forebay can increase the area of the cross section of water flow, so that the flow rate of water flow is reduced, silt can be deposited in the forebay and the sand collecting ditch, and after the silt is deposited to a certain degree, the silt early warning device in the sand collecting ditch is triggered to efficiently clean the deposited silt. The invention further provides a design method of the tree-shaped groove structure of the forebay of the pump station, the tree-shaped groove at the bottom of the forebay of the pump station is designed, silt can be automatically deposited when the pump station runs, a small amount of water is used for cleaning the bottom of the forebay of the pump station and collecting deposited silt in the forebay when the pump station stops, and the deposited silt is discharged by adopting an automatic machine. Sediment deposited in front of the pump can be prevented from blocking a water intake of the water pump, pump station blade abrasion is reduced, the service life of a pump station unit is prolonged, and water delivery and supply safety is guaranteed.
本发明公开了一种泵站前池树状沟槽冲沙结构及设计方法，树状沟槽冲沙结构主要包括平面和纵向扩散泵站前池，前池树状沟槽和末端半边漏斗形集沙沟。扩散状的前池能够增大过水断面面积，从而降低水流流速，使泥沙能够淤积在前池和集沙沟中，泥沙淤积到一定程度后，触发集沙沟中的泥沙预警装置，对淤积泥沙进行高效清理。本发明还提供了一种泵站前池树状沟槽结构的设计方法，通过设计泵站前池底部树状沟槽，泵站运行时可促使泥沙自动沉积，并在泵站停机时利用少量的水清洗泵站前池底部，收集前池中淤积泥沙，并采用自动机械排出，可避免泵前淤积泥沙堵塞水泵取水口，减少泵站叶片磨蚀，提高泵站机组寿命，保障输供水安全。
