Adjustable plate type column for forebay of pumping station
The column 6 is located, in use, in the forebay of a pumping station (shown in Fig. 6(b)) for directing waterflow and minimising turbulent flow 7. The column (detailed in Fig. 3) includes an adjusting plate (1), a rotating shaft (3) fixedly connected to the base of the forebay, a sleeve (2) rotatable around the shaft and limiting blocks or piers (4) located either side of the plate for limiting the rotation of plate about the shaft. The column located at the bend in the forebay, and the plate may rotate in response to high flow rate and may be limited to 20 degrees. The plate may be reinforced concrete or metal, and between 20-30 degrees to the incident flow direction. The sleeve may have outer and inner diameters of 1m and 0.5m respectively, and the plate may be 0.5m thick. Its width may be 1.5-2 times the width of the forebay (“B” Fig. 4). The location and angle of the column in the forebay path is selected to reduce the chance/size of turbulence (e.g. back eddies or “reflux” 7) at the pump sump 5 of the pump station.
