PURPOSE: A conduction type movable weir preventing damages of a water gate caused by obstacles is provided to prevent damages of a water gate because a hydraulic force of a hydraulic cylinder is not transferred to the water gate when an obstacle is arranged in the lower part of the water gate while lowering the water gate. CONSTITUTION: A conduction type movable weir preventing damages of a water gate caused by obstacles comprises a water gate(10), a rotary shaft, a support bracket, a driven link(40), a movable link(50), and a cylinder portion. The water gate blocks river water flowing from an upstream. The rotary shaft is fixed to the lower part of the water gate. The support brackets are arranged in both sides of the water gate, thereby supporting the rotary shaft to be moved. The driven shaft is fixed to the rotary shaft and comprises a guide groove. The movable link is fixed to the rotary shaft to be moved and comprises a hanging projection in a plane facing the driven link. The cylinder portion is composed of a hydraulic cylinder(61) and a piston rod(65). |
