Gate device for water conservancy project

The invention relates to the technical field of hydraulic engineering, in particular to a gate device for hydraulic engineering, which comprises a stand column, the top of the stand column is sleeved with a supporting device, and a protective device is fixedly mounted on the inner side of the stand column. According to the gate device for the water conservancy project, the protection performance of the whole device is facilitated through the arc-shaped protection plate, the drainage direction of water can be facilitated through the arc-shaped streamline, certain guiding performance is achieved, the waterproof plate acts on the bearing plate, the fixed connecting plate, the fixed bearing plate and the gravity block, and a certain protection effect is achieved; the bearing plate is used for resisting the pressure borne by the arc-shaped protective plate, a certain pressure restraining effect is achieved, the overall protection performance is achieved, meanwhile, the fixed bearing plate acts on the fixed bearing
