They are also called water projects. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, channels, etc. to achieve their goals. Among them, flood control gates are the main flood control and flood discharge equipment in water conservancy projects used to block floods.
[0003] In the prior art, publication number "CN221118431U" discloses a flood control gate for a water conservancy project, including a dam body, a filter screen and a hydraulic cylinder.

[0029] The slow-flow and water-blocking buffer unit on the surface of the engineering gate includes a buffer part, which includes rotating blades 8. The rotating blades 8 are arranged into several groups at intervals. A mounting column 81 is rotatably installed inside the water inlet channel 1.

[0030] The slow-flow water-blocking buffer unit on the surface of the engineering gate also includes a water-blocking part, which includes a floating plate 91. A movable slide 12 is provided on the inner wall of the water inlet channel 1. The floating plate 91 slides inside the movable slide 12. A floating cover 9 is installed at the bottom of the floating plate 91. A telescopic floating tube 93 is installed at the bottom of the floating cover 9.

When the movable gate 4 rises, the water-sealing gate plate 41 at the bottom of the movable gate 4 leaves the water diversion trough 31, and the water diversion trough 31 discharges the water flow in sections. When the external water flow passes through the rotating blades 8, the rotating blades 8 will rotate under the push of the water flow. When multiple groups of rotating blades 8 rotate, they will consume the kinetic energy in the water flow. The rotating blades 8 will drive the mounting column 81 to rotate. The mounting column 81 can convert the kinetic energy to the external power generation device, thereby reducing the kinetic energy impact in the water flow while improving the recovery and utilization of the kinetic energy of the water flow;
[0037] When the water flow in the canal surges, the water flow will quickly overflow the diversion shell 7 area.
