PURPOSE: An automatic sluice gate incorporating hydraulic cylinder is provided to simplify the structure of the sluice gate and the opening or closing operation by incorporating main components such as a rotation shaft, a fixing shaft, a cylinder and the like in a sealed space of a sluice gate enclosure. CONSTITUTION: A sluice gate to be automatically opened or closed by an hydraulic cylinder includes a supporting frame(60) supporting a sluice gate and having the matching size with the drainage, a fixing shaft(61) coupled at an upper end part of the supporting frame, a rotation shaft(62) formed outside the fixing shaft and fixed to the supporting frame for opening and closing the sluice gate, a rod fixing part(74) hinge-coupled with a rod(72) by a rod fixing pin(73) fixed to the center of the fixing shaft, a hydraulic cylinder part(70) hinge-coupled with the rod fixing part at an end and hinge-coupled with a center supporting die(67) at the other end for rectilinearly reciprocating by a piston operation, an inner frame(63) forming the structure of the sluice gate, a sluice gate enclosure(30) surrounding the hydraulic cylinder part and the inner frame, and hydraulic hoses(76) the supplying and discharging oil pressure to and from the cylinder.
