WATER INTAKE PORT OPENING AND CLOSING CONTROL DEVICE
To automatically control the opening and closing of a water intake port easily at low cost.SOLUTION: A water intake port opening and closing control device that controls the opening and closing of a water intake port X includes a floating member 104 that rises and falls according to a water level A. A water intake port gate 100 is lowered in conjunction with the ascending movement of a floating member 104, by controlling the water intake port X to be closed, the amount of water intake is suppressed when the water level A on a river side rises. The water intake port gate 100 includes a plug member 124 having a hollow structure provided with a hollow region 101 and fitted into a hole part 125 provided in the wall surface of the water intake port gate 100 on a water conduit side to prevent water from flowing into the hollow region 101, and a flow-down body member 121 that falls into water and moves downstream due to the water flow when a water level B rises. The plug member 124 is disengaged from the hole part 125 due to the movement of the flow-down body member 121, water flows into the hollow region 101 through the hole part 125, and the weight of inflowing water lowers the water intake port gate 100 to suppress the amount of water intake.SELECTED DRAWING: Figure 1
【課題】安価でかつ簡易に、取水口の開閉を自動制御すること。【解決手段】取水口Ｘの開閉を制御する取水口開閉制御装置は、水位Ａに応じて上昇・下降する浮き部材１０４を備え、浮き部材１０４の上昇の移動に連動して取水口ゲート１００を下降させて、取水口Ｘを閉じる制御により、河川側の水位Ａが上昇した場合に、取水量を抑制する。取水口ゲート１００が、中空領域１０１を備えた中空構造をなし、取水口ゲート１００の導水路側の壁面に設けられた孔部１２５にはめ込んで、中空領域１０１への水の流入を防止する栓部材１２４と、水位Ｂが上昇した場合に、水中に落下して、水流により下流側へ移動する流下体部材１２１とを備え、流下体部材１２１の移動により栓部材１２４が孔部１２５から外れ、孔部１２５を通じて中空領域１０１へ水が流入し、流入した水の重さで取水口ゲート１００を下降させ、取水量を抑制する。【選択図】図１
