Zusammenfassung: | The present invention relates to a hydraulic floodgate which prevents a leakage by being completely closed without increasing the weight of the hydraulic floodgate in the floodgate closed by the weight. According to the present invention, the floodgate installed to cross a waterway opens and closes the waterway and vertically moving while being inserted into a floodgate frame. A fixing roller can protrude from the inner side of the floodgate toward a side. The fixing roller moves the floodgate to the lower side while being inserted into a fixing cap formed on the side of the floodgate frame with a U-shaped cross section. After the floodgate moves down due to the weight of the floodgate, the fixing roller protrudes so that the floodgate additionally moves down by the fixing cap. Therefore, the hydraulic floodgate can prevent the leakage without increasing the weight of the floodgate as an adhesive force of the floodgate to the bottom surface is expanded.
본 발명은 자중에 의하여 닫히게 되는 수문에서, 자중을 크게 하지 않고도 수문이 완전히 닫히게 하여 누수가 발생하지 않도록 하는 유압 수문에 관한 것이다. 본 발명은 수로를 가로질러 설치되는 수문은 수문 프레임에 끼워진 채로 상하 이동되며 수로를 개폐함에 있어서, 수문의 내측에서 측면을 향하여 고정롤러가 돌출시킬 수 있도록 하되 상기 고정롤러는 단면이 ㄷ자 형태를 갖는 수문 프레임의 측면에 형성된 고정캡에 끼워지면서 수문을 하강시킴으로써 이루어지는 것으로, 수문이 자중에 의하여 하강된 후 고정롤러를 돌출시켜 고정캡을 타고 추가 하강이 이루어지게 함으로써 수문의 저면 밀착력이 확대되어 자중을 높이지 않고도 누수가 방지되는 것이다. |
