The present invention relates to a floodgate. The objective of the present invention is to utilize an upper space of a slab and to facilitate the installation and separation of a floodgate body and the maintenance and repair of the floodgate. The floodgate comprises: a floodgate body; a floodgate frame having guide grooves formed on both side surfaces to vertically slide the floodgate body, a slab formed in the upper part, and an opened groove formed in the front side of the slab; a winch installed inside the floodgate body; and transfer members having one end connected to the winch and the other end fixed on the slab. Saddles to fix the transfer members are fixed on the slab. The transfer members are in a pair, are transversely fixed by a coupling rod in the upper part. The multiple saddles are fixed on the coupling rod. Multiple variable rollers are installed in the side surface of the floodgate body. A watertight rubber is attached to the bottom of the floodgate body such that a watertight angle can be coupled. The variable roller comprises: a roller body vertically slid on the guide grooves of the floodgate frame; a fixed shaft protruding from the center of one side of the roller body; fixed flanges fixed on the fixed shaft and having multiple penetration holes; screw rods coupled to the penetration holes of the fixed flanges and having one end coupled to the floodgate body; and fixing nuts to fix the fixed flanges on the screw rods. |
