DETAILED DESCRIPTION

[0019] like Figure 1-3 As shown, a dam cleaning device for water conservancy and hydropower comprises a support plate 1, a front shovel plate 2, a water delivery pressurizing mechanism 3, and an elastic cutting assembly 4. The front shovel plate 2 is fixedly connected to one end of the support plate 1, and the front shovel plate 2 is arranged to be tilted downward. The angle between the front shovel plate 2 and the bottom wall of the support plate 1 is less than 180 degrees, so that the water flow can be shoveled up. The water delivery pressurizing mechanism 3 is arranged on both sides of the upper wall of the support plate 1. The water flow flows downward and is opposite to the front shovel plate 2. The water flow is shoveled up by the front shovel plate 2 and passed into the water delivery pressurizing mechanism 3. The water delivery pressurizing mechanism 3 is used to shovel the water flow. The pressing mechanism 3 guides the water flow and presses down the support plate 1 to keep the device stable and fit the surface of the dam. The elastic cutting component 4 is rotatably connected to the bottom wall of the support plate 1, rotates on the bottom wall of the support plate 1, fits the surface of the dam and rotates to achieve cutting and scraping. Support rubber strips 17 are connected to both sides of the bottom of the support plate 1. The bottom wall of the support rubber strip 17 is located between the positioning plate 7 and the cutting strip 8, which is used to raise the bottom wall of the support plate 1 so that the support plate 1 slides along the surface of the dam and supports the elastic cutting component 4 at the same time, leaving space for the rotation of the elastic cutting component 4.

[0020] like Figure 2 and Figure 3 As shown, in order to realize the rotary cleaning of the dam surface and the scraping of moss and algae, the elastic cutting assembly 4 includes a protective shell 5, a rotating motor 6, a positioning plate 7 and a cutting strip 8. The protective shell 5 is fixedly connected to the center of the upper wall of the support plate 1, and the rotating motor 6 is fixedly connected to the inner bottom wall of the protective shell 5. The output end of the rotating motor 6 passes through the bottom wall of the protective shell 5 and the support plate 1 and is rotated below the support plate 1. The positioning plate 7 is fixedly connected to the output end of the rotating motor 6. The positioning plate 7 is bent downward at both ends. The cutting strip 8 is arranged between the opposite inner walls of the positioning plate 7. The cutting strip 8 is symmetrically arranged and has a downwardly convex arc shape. The rotating motor 6 is protected by the protective shell 5.

[0021] like Figure 1-2As shown, in order to improve the stability of the device, the support plate 1 is pressed downward, and at the same time, the cutting strip 8 is ensured to fit the surface of the dam. The water supply and pressure mechanism 3 includes a partition 9 and a punching pipe 10. The partition 9 is fixedly connected to both sides of the upper wall of the support plate 1 adjacent to the front shovel plate 2. The partitions 9 are evenly spaced and arranged. The evenly spaced partitions 9 are symmetrically arranged with the protective shell 5 as the center. A water supply channel 11 is formed between adjacent partitions 9. The punching pipe 10 is fixedly connected to the end of the support plate 1 away from the front shovel plate 2. The punching pipe 10 is connected to the water supply channel 11. The punching pipe 10 is tilted downward. After the front shovel plate 2 scoops up the water flow, it enters the water supply channel 11 between the partitions 9. The water flow presses downward on both sides of the support plate 1, and the water inside the water supply channel 11 flows into the punching pipe 10. The water flow direction is changed by the punching pipe 10, and the water flow is tilted downward and pressurized to spray out to wash the cleaned and scraped dam surface.

[0022] like Figure 1 As shown, in order to further increase the cleaning effect of the dam surface, scraping components 13 are rotatably connected on both sides of the support plate 1. The scraping components 13 include a connecting rod 14, a sleeve 15 and a scraper 16. The connecting rod 14 is rotatably connected to the outer wall of the separated partition 9. The connecting rod 14 is arranged in an n-shape. The sleeve 15 is rotatably connected to the middle section of the connecting rod 14. The scraper 16 is wound around the outer wall of the sleeve 15. The scraper 16 is arranged in a spiral shape. The connecting rod 14 is rotated to make the sleeve 15 and the scraper 16 contact with the dam surface. When water flows out through the stamping pipe 10, the scraper 16 is pushed to make the sleeve 15 rotate on the outer wall of the middle section of the connecting rod 14, thereby achieving further scraping and cleaning of the dam surface.

[0023] Among them, in order to reduce the impact on the protective shell 5, a flow-blocking net 12 is provided in the middle of the stamping tube 10 near one end of the support plate 1. The flow-blocking net 12 slows down the flow of water in the middle of the upper wall of the support plate 1, allowing the water to pass slowly, thereby reducing the impact on the protective shell 5. A connecting block 18 is provided in the middle of the outer wall of the separated partition 9, and a connecting hole 19 is opened in the center of the connecting block 18 for connecting a rope.

[0024] When in use, the operator inserts the rope into the connection holes 19 in the connection blocks 18 on both sides of the device, and moves the device on the dam surface by retracting and releasing the rope. When cleaning, the rope is extended to the longest, and the device is located at the lower part of the dam slope. Under the impact of the water flow, the front shovel plate 2 scoops up the water flow and passes it into the water delivery channel 11, and the support plate 1 is pressed downward by the water flow to keep the device stable and fit the dam surface.

[0025] The rotary motor 6 is driven to rotate, and the cutting strip 8 under the support plate 1 is driven to rotate. The cutting strip 8 is an elastic steel strip, which is pressed down by the support plate 1 and contacts the surface of the dam. When rotating, the thin side wall of the cutting strip 8 is cut and scraped;

[0026] The water in the water delivery channel 11 flows into the punching pipe 10, changes the flow direction of the water through the punching pipe 10, and sprays out obliquely downward under pressure to wash the cleaned and scraped dam surface;

[0027] Finally, when the water flows out through the punching pipe 10, it pushes the scraper 16, causing the sleeve 15 to rotate on the outer wall of the middle section of the connecting rod 14, thereby further scraping and cleaning the surface of the dam.

[0028] Although the embodiments of the utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents. In short, if those skilled in the art are inspired by them and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the scope of protection of the utility model.
