[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a dredging device for water conservancy engineering channels, the dredging device for water conservancy engineering channels includes: a movable base plate 1, a flushing mechanism 2 installed on the top of the movable base plate 1, a support 3 installed on the top of the movable base plate 1, a dredging mechanism 4 installed inside the support 3, a movable baffle 5 and a movable scraper 6 installed at the bottom of the movable base plate 1, the movable baffle 5 and the movable scraper 6 are placed in parallel, a movable groove 7 is opened on the side wall of the movable scraper 6, a connecting plate 8 is installed inside the movable groove 7 through a bearing, and one end of the connecting plate 8 is installed on the side wall of the movable baffle 5 through a bearing;
[0023] In use, the flushing mechanism 2 is located on top of the movable base plate 1, and the sludge removal mechanism 4 is located inside the support 3. It can be moved and sludge removed inside the channel through the movable base plate 1. During the movement, the movable baffle 5 and the movable scraper 6 can be adjusted synchronously through the connecting plate 8 and the bearing. The movable baffle 5 is located in front of the movable wheel at the bottom front of the movable base plate 1 to separate the sludge and prevent the sludge from affecting the forward movement of the movable wheel. The movable scraper 6 can easily move and stir the sludge through the sludge removal mechanism 4 to flush it out, preventing the sludge from flowing with the water to the cleaned area after the channel is cleaned.
[0024] Example 2: Based on Example 1, a structure is provided for moving and fixing the connecting plate 8. A moving groove 9 is provided through the top of the connecting plate 8. A pull rod 10 is installed through the inside of the moving groove 9. A support rod 11 is sleeved on the outer surface of the pull rod 10. The bottom end of the support rod 11 is located at the top of the connecting plate 8. The tops of the pull rod 10 and the support rod 11 both penetrate the inside of the movable base plate 1. A lifting plate 12 is installed on the top of the pull rod 10. Rotating plates 13 are installed on both sides of the lifting plate 12. The bottom end of the rotating plate 13 is located at the top of the support rod 11.
[0025] In use, the pull rod 10 passes through the interior of the moving groove 9 of the connecting plate 8. The pull rod 10 can drive the connecting plate 8 to move upward. When the connecting plate 8 moves upward, the pull rod 10 can move inside the moving groove 9, which facilitates the lifting and lowering of the connecting plate 8. This allows the movable baffle 5 and movable scraper 6 to rotate and adjust their positions as the connecting plate 8 rises and falls, improving their performance. The support rod 11 can fix the connecting plate 8 and drive it downward to adjust the placement of the movable baffle 5 and movable scraper 6. This ensures that the bottom of the movable baffle 5 and movable scraper 6 is at the lowest point, preventing silt from flowing into the clean channel and avoiding silt from affecting the movement of the movable wheels of the movable base plate 1. The outer end of the rotating plate 13 rotates to the top of the support rod 11, which helps to fix the pull rod 10 and the support rod 11 together. This allows the pull rod 10 and the support rod 11 to clamp the connecting plate 8 vertically and then drive it to move up and down.
[0026] Example 3: Based on Example 2, a structure is provided to facilitate the movement and fixation of the pull rod 10 and the support rod 11. Threaded rods 14 and limiting rods 15 are installed on both sides of the lifting plate 12. The threaded rods 14 and limiting rods 15 are placed parallel to each other and are located on the upper surface of the movable base plate 1. A fixing plate 16 is installed on the top of the threaded rods 14 and the limiting rods 15. Several evenly distributed array of long plates 17 are installed on the top of the threaded rods 14. The long plates 17 are located on the top of the fixing plate 16. A sliding groove 18 is opened inside the fixing plate 16. A locking block 19 is installed inside the sliding groove 18. The locking block 19 moves between two adjacent long plates 17. A spring 20 is installed on the side wall of the locking block 19. One end of the spring 20 is fixed to the top of the fixing plate 16.
[0027] In use, the long plate 17 drives the threaded rod 14 to rotate, and under the action of the limit rod 15, it drives the lifting plate 12 to move up and down, which in turn drives the pull rod 10 and the support rod 11 to move and adjust. Then, the locking block 19 moves between two adjacent long plates 17 under the outward pushing force provided by the spring 20 to fix the threaded rod 14, preventing the threaded rod 14 from rotating and thus preventing the lifting plate 12 from moving.
[0028] In actual use, the flushing mechanism 2 is located on top of the movable base plate 1. The sludge removal mechanism 4 is inside the support 3, allowing for easy movement and sludge removal within the channel via the movable base plate 1. The pull rod 10 is movable within the moving groove 9, facilitating the lifting and lowering of the connecting plate 8. This allows the movable baffle 5 and movable scraper 6 to rotate and adjust their positions as the connecting plate 8 rises and falls, improving their performance. The support rod 11 secures the connecting plate 8 and moves it downwards to adjust the placement of the movable baffle 5 and movable scraper 6, ensuring their bottom ends are at the lowest point to prevent sludge from flowing into the clean channel and to avoid sludge affecting the movement of the movable wheels on the movable base plate 1. The outer end of the rotating plate 13 rotates to the top of the support rod 11, facilitating the movement of the pull rod 10 and... The support rods 11 are fixed together so that the connecting plate 8 can be clamped up and down by the pull rod 10 and the support rod 11, and the connecting plate 8 can be moved up and down. The long plate 17 drives the threaded rod 14 to rotate. Under the action of the limit rod 15, the lifting plate 12 can be moved up and down. In turn, the pull rod 10 and the support rod 11 can be moved and adjusted. Then, the locking block 19 moves between the two adjacent long plates 17 under the outward pushing force provided by the spring 20 to fix the threaded rod 14, so as to prevent the threaded rod 14 from rotating and thus prevent the lifting plate 12 from moving. The movable baffle 5 is located at the front end of the movable wheel at the bottom of the movable base plate 1 to separate the silt and prevent the silt from affecting the forward movement of the movable wheel. The movable scraper 6 facilitates the movement and agitation of the silt through the sludge removal mechanism 4 to flush out the silt and prevent the silt from flowing with the water to the cleaned area after the channel is cleaned.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
