PROBLEM TO BE SOLVED: To provide a water channel opening/closing device that is lightweight and compact, can be manufactured at low cost, and also can have a door body easily elevated even in the absence of supply of electric power from a commercial power supply.SOLUTION: A water channel opening/closing device A1 comprises a main body part 2, a hydraulic cylinder 3, a door body 4, and a hydraulic oil supply device 5. The main body part 2 has an upper wall part 2a which extends horizontally in a direction crossing a direction in which an agricultural water channel 1 extends above the agricultural water channel 1, and two side wall parts 2b, 2c which extend downward from the upper wall part 2a and are parallel with each other. Here, components of the water channel opening/closing device A1 except the hydraulic cylinder 3 are arranged at an upper wall outer edge inner space part consisting of a space part right below an upper wall outer edge inner plane region surrounded with outer edges of the upper wall part in plan view.SELECTED DRAWING: Figure 1
【課題】軽量かつコンパクトであり、低コストで製作することができ、また商用電源が電力の供給を停止したときでも容易に扉体を昇降させることができる水路開閉装置を提供する。【解決手段】水路開閉装置Ａ１は、本体部２と、油圧シリンダ３と、扉体４と、作動油供給装置５とを備えている。本体部２は、農業用水路１の上方で該農業用水路１が伸びる方向と直交する方向に水平に延びる上壁部２ａと、上壁部２ａから下方に延びる互いに平行な２つの側壁部２ｂ、２ｃとを有している。ここで、油圧シリンダ３を除く水路開閉装置Ａ１の構成要素は、平面視において上壁部の外縁によって囲まれた上壁外縁内平面領域の直下の空間部からなる上壁外縁内空間部に配置されている。【選択図】図１
