An automatic opening/shutting device for a channel is provided to prevent the loss of electric power for keeping a sluice gate at the closed state by securing bearing strength and to make the outflow of deposits easy. An automatic opening/shutting device for a channel contains: a concrete channel(5); a sluice gate(10) installed on the concrete channel and opened/closed according to storage capacity; a hydraulic generator composed of a storage capacity sensor, a pressure generator and a controller to release pressure while closing and to supply pressure while opening; a hydraulic device(20) composed of a hydraulic cylinder(22) and a hydraulic rod(24) and connected with a hydraulic generator to get supplied with hydraulic pressure; a fixing link(16) fixed to a bracket(12) welded to a frame of the base of the channel by a fixing shaft(14); and a primary link(30) and a secondary link(40) connected to the fixing link and the hydraulic device of the sluice gate by hinges(32,34,36), wherein the primary link connected to the fixing link and the secondary link connected to the hydraulic device are connected by hinges to be foldable by opening and shutting a sluice gate and the secondary link is connected to the side wall of a sluice gate by a fixing pin(50) to supply bearing strength for keeping the sluice gate at the closed state. |
