Technical Field

[0001] The present application relates to the technical field of water conservancy projects, and in particular to a reservoir dam. Background Art

[0002] Dams can intercept water flows in rivers and channels and raise water levels to form reservoirs. Reservoir dams can store water, regulate runoff, and concentrate water flows for use in flood control, water supply, irrigation, hydroelectric power generation, and improved navigation.

[0003] Regarding the above-mentioned related technologies, the applicant believes that as the pollutants in urban rivers continue to increase, the pollutants in reservoirs are also increasing. Generally, garbage will float on the water surface of reservoir dams. When there is a lot of garbage floating on the water level of reservoir dams, it will seriously affect the normal operation of the dam. The floating garbage is usually scattered everywhere, making it difficult to clean up, so there is still room for improvement. Utility Model Content

The rising guide block is higher than the water surface of the spillway and is thus misaligned with the floating garbage. Then the guide block descends to the water surface of the corresponding spillway, and then drives the horizontal sliding through the driving structure, thereby pushing the floating garbage to concentrate on one side of the dam pier, solving the problem of the floating garbage being scattered everywhere, and cleaning up the floating garbage in a centralized manner, improving the convenience of cleaning, and reducing the impact of garbage on the normal operation of the dam.

When the guide block collects garbage to one side of the dam pier, the silt at the bottom of the drain outlet can be scraped off by the silt-clearing plate, thereby helping to reduce the problem of reduced drainage efficiency due to sedimentation.

[0018] Preferably, deformable limiting plates are fixed on both sides of the silt cleaning plate, and L-shaped rods installed in the retention grid plate are fixed on the side walls of the silt cleaning plate.

After descending, it drives the floating garbage to one side of the dam pier 1 for collection and cleaning; in addition, when the water level rises to the movable slide 4, the guide block 32 does not need to be lowered at this time, and the centralized cleaning of garbage can still be achieved through the movement of the guide block 32 and the push plate 33, which is more practical.
