CONSTITUTION: A rope type hydraulic floodgate includes a hydraulic cylinder(40), a pair of moving rollers(80), a fixed roller(50), a rope(90), a rack gear(11), a pinion gear(21). The hydraulic cylinder is installed at the upper side of a supporting frame(30) installed at the upper side of a floodgate frame(10). The moving rollers are installed at the cylinder shaft(41) of the hydraulic cylinder and move up and down. The fixed rollers are respectively installed at both sides of the upper side of the flood gate(20) fit into the floodgate frame. The ropes are respectively fixed to both sides of the lower side of the supporting frame. The ropes are hung on the moving rollers and then are hung on the fixed rollers. The rack gears are vertically installed at the floodgate frame. The pinion gears are installed at both sides of the floodgate and are engaged with the rack gear. The pinion gears are fixed to both sides of a rotary shaft(22) which is installed across the floodgate, and rotate when the floodgate moves.
