SLUICE GATE

WIPO Patent Application WO/2023/140714

A1

The present invention relates to a sluice gate. The sluice gate according to the present invention is for adjusting the water level of a water discharge unit and a water reservoir unit by opening and closing a discharge port formed on a side wall of the water reservoir unit containing water, and comprises: a hinge coupled to the top of the discharge port of a sidewall of the water reservoir unit; a flap gate coupled to the hinge unit and rotating up and down around the hinge unit, wherein the flap gate is rotated downward to close the discharge port when overlapped with the sidewall of the water reservoir unit and is rotated upward to open the discharge port; a fan-shaped pull string pulley coupled to an upwardly facing surface of the flap gate when the flap gate is horizontal; a pull string lifting means installed above the water reservoir unit; and a pull string having one end connected to the pull string lifting means and the other end coupled to the flap gate, wherein a portion of the pull string is wound around the outer periphery of the pull string pulley that moves the flap gate so as to close the discharge port by converting a horizontal motion caused by the vertical lifting means into a rotational motion by means of the fan-shaped pull string pulley attached to the flap gate.
