[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] See also Figure 1-4The utility model provides a technical solution: a sludge cleaning device for water conservancy projects, including: a pipe base 1, an installation box 2, a motor 3, a bidirectional screw 4, a moving block 5, a collar 6, a hinged rod 7, a support frame 8, a roller 9, a fixed block 10, a gear 11, a gear ring 12, a mounting frame 13, a cleaning plate 14, a pumping rod 15, a spring 16, a water tank 17 and a water spray pipe 18.
[0027] When using the sludge cleaning device for water conservancy projects, first Figure 1 and Figure 2 As shown, the installation box 2 is installed inside the pipeline base 1, the bidirectional screw rod 4 is installed through the middle of the installation box 2, and the bidirectional screw rod 4 is rotatably connected to the inside of the installation box 2, the moving block 5 is rotatably connected to the outside of the bidirectional screw rod 4, and the moving block 5 is symmetrically arranged along the central axis of the bidirectional screw rod 4, the moving block 5 and the moving direction of the moving block 5 are opposite, and the longitudinal section of the moving block 5 is a "cross" structure, the outer end of the moving block 5 is fixedly connected to the collar 6, and the outer end of the moving block 5 is slidably connected to the through groove opened inside the installation box 2, the collar 6 is slidably connected to the outside of the installation box 2, the two ends of the hinged rod 7 are rotatably connected to the collar 6 and the support frame 8 respectively, the inner end of the support frame 8 is rotatably connected to the left and right ends of the installation box 2, and the roller 9 is rotatably connected to the outside of the support frame 8;
[0028] Observe and wait for the diameter of the cleaned pipe, rotate the bidirectional screw rod 4 to make the moving block 5 move on the outside of the bidirectional screw rod 4, and the two moving blocks 5 move in different directions. When the moving block 5 moves, it drives the collar 6 to slide on the outside of the installation box 2. The through groove opened inside the installation box 2 has a limiting effect on the moving block 5. The movement of the collar 6 causes the hinge rod 7 to rotate, and the hinge rod 7 therefore pushes or pulls the support frame 8 to rotate along its hinge point with the installation box 2. After adjusting the support frame 8 to the appropriate position, stop rotating the bidirectional screw rod 4. The self-locking function of the bidirectional screw rod 4 ensures that the position of the support frame 8 is fixed, so that the device can be applied to pipes of different diameters, expanding the scope of application of the device.
[0029] like Figure 1 、 Figure 3 and Figure 4As shown, the fixed block 10 is fixedly mounted on the middle outer side of the mounting box 2, the right end of the gear 11 is fixedly connected to the output end of the motor 3, and the motor 3 is fixedly mounted inside the fixed block 10, the gear 11 is rotatably connected to the fixed block 10, the gear ring 12 is connected between the fixed block 10 and the fixed block 10, and the gear ring 12 is sleeved on the middle outer side of the mounting box 2, the outer end of the gear ring 12 is slidably connected to the inside of the fixed block 10, the gear 11 and the gear ring 12 are meshed for transmission, the mounting frame 13 is fixed to the outer side of the gear ring 12, the mounting frame 13 is arranged in an annular shape at equal angles along the center point of the gear ring 12, the cleaning plate 14 is slidably connected to the inside of the mounting frame 13, and the outer end of the cleaning plate 14 is fixedly mounted with bristles, the inside of the mounting frame 13 is installed with a pumping rod 15, and the outer side of the pumping rod 15 is sleeved with a spring 16, the pumping rod 15 is in a movable state and is engaged with a groove opened inside the cleaning plate 14, and the two ends of the spring 16 are fixedly connected to the mounting frame 13 and the pumping rod 15 respectively;
[0030] The position of the cleaning plate 14 is adjusted according to the diameter of the pipe and the extended position of the support frame 8. The draw rod 15 is pulled outward to elastically deform the spring 16. The inner end of the draw rod 15 slides out of the groove provided inside the cleaning plate 14. After the cleaning plate 14 is pulled to adjust it to a suitable position, the draw rod 15 is released. Under the elastic action of the spring 16, the draw rod 15 is pushed to engage with the corresponding new groove, completing the fixing of the position of the cleaning plate 14 and the mounting frame 13, thereby improving the practicality of the cleaning plate 14.

The motor 3 starts and drives the gear 11 to rotate. The gear 11 engages with the gear ring 12 to control the installation frame 13 and the cleaning plate 14 to make a circular motion, and the silt on the inner wall of the pipeline base 1 is cleaned. The water tank 17 stores water through a hose, and the water is sprayed out from the water spray pipe 18 to assist in cleaning the silt, thereby improving the cleaning efficiency.
