The present invention relates to a hydraulic movable weir. Disclosed is a hydraulic movable weir including a weir gate that is provided between weir frames and is opened/closed while rotating about a main shaft in a lower end portion; a main arm whose one end portion is coupled with the main shaft for integral rotation with the main shaft; a link unit that is configured to have a first link and a second link which are operated in interworking with the main arm so that the main arm rotates about the main shaft, an x link module including a central shaft, and a guide link; a driving unit that is configured to have a piston rod which is hinge-coupled with a lower end of the first link of the link unit and a hydraulic cylinder and provides power for an operation of the link unit; and a locking unit that is engaged with a stopper which is provided at a lower end of the first link, restricts the operation of the link unit, and maintains an opening/closing angle of the weir gate. |
