[0002] A hydraulic dam is a hydraulic concrete lifting dam, a relatively simple movable dam technology in water conservancy technology. It is widely used in agricultural irrigation, fisheries, ship locks, seawater tidal barriers, urban river landscape projects, and small hydropower stations.
[0003] After checking the publication number: CN221441438U, a hydraulic dam convenient for diverting and discharging flood is disclosed. This technology discloses "a hydraulic dam convenient for diverting and discharging flood, comprising a rotating dam surface mechanism, a dam surface lifting mechanism and a hydraulic cylinder; the rotating dam surface mechanism: it comprises a gate leaf, a rotating hole and a second support hinge seat, the rear lower end of the gate leaf is provided with a rotating hole, the rotating hole is rotatably connected to the upper end of the second support hinge seat through a pin shaft, and the upper end of the rear side surface of the gate leaf is provided with a rotating seat; the dam surface lifting mechanism: it is respectively arranged on the left and right sides of the upper end of the gate leaf; the hydraulic cylinder one: its lower end is rotatably connected to the first support hinge seat, and the upper end of the telescopic end of the hydraulic cylinder one is rotatably connected to the rotating seat, the dam surface lifting mechanism comprises a dam surface, a fixed bracket, a hydraulic cylinder two and a fixed seat, the fixed seats are respectively fixedly connected to the left and right sides of the rear side surface of the gate leaf" and other technical solutions, which have the technical effects of "increasing the water storage capacity by raising the dam surface to avoid the flood discharge exceeding the maximum water flow capacity of the downstream during diverting and discharging flood";
[0004] The above scheme achieves diversion and flood discharge by adjusting the interception height; however, since the rise and fall of the dam surface is driven and adjusted by hydraulic cylinders, although the upper end of the dam surface is curved, which reduces the impact of water flow on the hydraulic cylinders, in extreme weather or sudden floods, the force of the water flow may be stronger, resulting in the protective effect of the curved dam surface may not be sufficient to completely eliminate the risk of impact on the hydraulic cylinders.
