摘要

PURPOSE: An automatic rotation floodgate system is provided to reduce the manufacture and manufacturing cost and to prevent the damage by releasing impact applied to a floodgate and a support structure. CONSTITUTION: An automatic rotation floodgate system is composed of a waterway opening and shutting unit(110), a rotation support unit(120), and a control unit(130). The waterway opening and shutting unit has a floodgate(111) and a weight(112). The weight is extended to be inclined at the fixed angle from the lower end to the lower part of the upstream and is arranged unequally. The rotation support unit is horizontally installed in the waterway opening and shutting unit as a rotation center. Both ends of the rotation support unit are supported to left and right side walls(210,220) of a waterway structure(200). The control unit includes an opening stopper(131) and a closing stopper(132). The control unit controls the opening and closing positions of the floodgate.
