PURPOSE: A device for making a water gate automatically descend is provided to make a water gate automatically descend by releasing the brake unit of a winch by floating a buoyant member and rotating a connecting shaft by a steel rod connected to the buoyant member. CONSTITUTION: A device for making a water gate automatically descend comprises a buoyant member(112) and a link member(120). The buoyant member is installed in a buoyant pipe(110). The buoyant member floats or descends by buoyancy according to the change of water level. The buoyant pipe is connected to a water pipe(104) for receiving water and is vertically installed. The link member comprises a plurality of connecting shafts(122). The connecting shafts are installed to be able to rotate by a steel rod(114) connected to the buoyant member. If the lever of the water in the buoyant pipe exceeds a predetermined threshold, the water-gate descending device floats the buoyant member. |
