WATER INTAKE DEVICE
PROBLEM TO BE SOLVED: To provide a water intake device capable of suppressing shortage of a water intake amount even when a water level is lowered.SOLUTION: A water intake device 10 for controlling a water flow rate of a water channel 11 includes a water intake gate 20 forming a water intake opening 24 between a lower end surface 22 and a bottom 90 of the water channel 11, a gate supporting part 30 for elevatably supporting the water intake gate 20 within a range in which a lower end of the water intake gate 20 is not brought into contact with the water channel 11, a lock part 40 for suppressing elevating of the water intake gate 20 by fixing the gate supporting part 30, a float 52 vertically moved in accordance with fluctuation of a water level in the water channel 11 on the upstream side of the water intake gate 20, a driving rod 54 vertically moved in accordance with movement of the float 52 and releasing fixing of the gate supporting part 30 of the lock part 40 when the float 52 is lifted to a prescribed position, and a flow rate adjusting part 60 for changing a shut-off amount of the opening 24 in accordance with the water level in the water channel 11 on the upstream side of the water intake gate 20.
【課題】水位が低下しても取水量が不足することを抑制する取水装置を提供する。【解決手段】水路１１の流水量を制御するための取水装置１０であって、下端面２２と水路１１の底部９０の間に取水用の開口部２４を形成する取水ゲート２０と、取水ゲート２０の下端が水路１１と接しない範囲で昇降可能に支持するゲート支持部３０と、ゲート支持部３０を固定することで取水ゲート２０の昇降を抑制するロック部４０と、取水ゲート２０よりも上流側の水路１１の水位の変動に伴い鉛直方向に移動するフロート部５２と、フロート部５２の移動に伴って鉛直方向に移動し、フロート部５２が所定の位置まで上昇した場合にロック部４０のゲート支持部３０の固定を解除する駆動ロッド５４と、取水ゲート２０よりも上流側の水路１１の水位に応じて開口部２４の遮蔽量を変化させる流量調整部６０と、を有する。【選択図】図１
