Dam body structure for preventing reservoir sediment deposition

The utility model discloses a dam body structure for preventing reservoir sediment deposition, which belongs to the field of reservoir dam bodies, and comprises a reservoir dam body, a gate is movably sleeved on the side surface of the reservoir dam body, the gate comprises an anti-corrosion layer, a compression-resistant layer and a reinforcing layer, the anti-corrosion layer is arranged outside the compression-resistant layer, the compression-resistant layer is arranged outside the reinforcing layer, and the reinforcing layer is arranged outside the anti-corrosion layer. A connecting block is fixedly connected into the gate, and the side face of the connecting block is movably connected with a rotating screw in a sleeved mode. By arranging a connecting block, a rotating screw rod, a forward and reverse motor, a movable block, a fixed box, an electric push rod, a scraper plate and a positioning rod, in the use process of the gate, the forward and reverse motor drives the movable block to horizontally move, t
