Abstract:
The purpose of the present invention is to provide a non-motorized conductive movable weir to enable users to naturally open or close a floodgate according to the water level, although a manual method using a hydraulic cylinder or a motor requires users to manually operate the hydraulic cylinder or the motor to open or close the floodgate. The present invention increases use efficiency and enables users to efficiently open or close the floodgate by allowing them to naturally open or close the floodgate according to the water level without using a separate power source such as hydraulic cylinder.

Abstract:
PURPOSE: A discharge type water gate, capable of preventing water leakage by using a pressing part, is provided to prevent gaps which can cause water leakage by contacting a gate closely to a drain outlet. CONSTITUTION: A discharge type water gate comprises a body(110), a gate(120), a rod(140), a winch(150), and a pressure unit. The body comprises a drain outlet. The drain outlet is communicated with a discharge pipe installed to the upper stream. The gate ascends and descends according to a guide unit in order to open and close a ring-shaped guide of the drain outlet. The guide unit is formed inside the body. The rod is expanded upward the body from the top of the gate. The winch offers the power to lift the gate by connecting with the rod. The pressure unit is respectively formed on the rear both side of the gate. The pressure unit is elevated to closely contact the gate to the drain outlet.
