SLUICE GATE LIFTING DEVICE
To always raise and lower a sluice gate depending on a water level in a canal.SOLUTION: A sluice gate lifting device 100 comprises: a fluid pressure actuator 20 that is driven by the pressure of the supplied working water to raise and lower a gate 5; and a fluid pressure generation unit 30 that generates the pressure of the working water supplied to the fluid pressure actuator 20. The fluid pressure generation unit 30 has a first flow path portion 31 and a second flow path portion 32 provided in the gate 5, and communicates an upstream side and a downstream side of the gate 5 through the first flow path portion 31 and the second flow path portion 32. The flow path cross-sectional area of the first flow path portion 31 is set smaller than the flow path cross-sectional area of the second flow path portion 32. The fluid pressure actuator 20 is driven according to the pressure difference between the pressure in the first flow path portion 31 and the pressure in the second flow path portion 32.SELECTED DRAWING: Figure 1
【課題】水路の水位に応じて水門のゲートを常時昇降させる。【解決手段】水門ゲート昇降装置１００は、供給される作動水の圧力によって駆動しゲート５を昇降させる流体圧アクチュエータ２０と、流体圧アクチュエータ２０へ供給される作動水の圧力を生成する流体圧生成部３０と、を備える。流体圧生成部３０は、ゲート５に設けられる第１流路部３１及び第２流路部３２を有し、第１流路部３１及び第２流路部３２を通じてゲート５の上流側と下流側とを連通する。第１流路部３１の流路断面積は、第２流路部３２の流路断面積よりも小さく設定され、流体圧アクチュエータ２０は、第１流路部３１内の圧力と第２流路部３２内の圧力との圧力差に応じて駆動する。【選択図】 図１
