Description

Technical Field

[0001] This utility model relates to the field of reservoir dam repair technology, specifically a device for repairing cracks in reservoir dams. Background Technology

[0002] A reservoir dam crack repair device is an engineering equipment or system specifically designed for the effective repair and reinforcement of cracks appearing on the dam body. It aims to ensure the structural integrity and stability of the reservoir dam through a series of scientific and rational technical means, preventing safety hazards such as leakage and structural damage caused by cracks, thereby ensuring the safe and stable operation of the reservoir's comprehensive functions, including water storage, flood control, and irrigation.

[0003] The existing patent announcement number CN220789364U discloses a crack and groove repair device, which relates to the technical field of repair devices. The pipe is connected to the supply box, and a flange is installed on the top surface of the pipe. The pipe and the flange together form a connection structure. This solves the problem that existing devices lack an effective guiding and filling structure, which requires manual operation by holding the corresponding filling tube towards the crack. However, since the cracks are irregular, frequent manual adjustments are required, which has limitations. By setting up a guide frame that can be adjusted laterally and a movable frame that can be adjusted longitudinally inside the guide frame, the device can be used by leading out the supply tube located outside the supply box and inserting the supply tube into the internal position of the movable frame. Then, the lateral and longitudinal positions of the movable frame can be adjusted by electric push rods A and B, respectively, to achieve a more practical purpose.

[0004] While the above technical solution enables adjustment of the lateral and longitudinal positions of the supply pipe, the grout may become viscous and difficult to mix evenly if stored in the supply box for a long time, and may even clump, affecting the smoothness and uniformity of grouting. Therefore, we provide a device for repairing cracks in reservoir dams. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figures 1-4As shown, in this embodiment, a reservoir dam crack repair device includes a mobile vehicle body 11. A mixing tank 12 is installed inside the mobile vehicle body 11. A first motor 13 is installed at the bottom of the mixing tank 12. A support column 31 is fixedly connected to the bottom of the mixing tank 12 and fixedly connected to the top of the mobile vehicle body 11. The first motor 13 is fixedly connected to the top of the mobile vehicle body 11. A rotating shaft 14 is installed at the top of the first motor 13. Three stirring rods 15 are installed outside the rotating shaft 14. A cleaning plate 16 is installed at the end of each stirring rod 15 away from the rotating shaft 14. The output end of the first motor 13 is fixedly connected to the bottom end of the rotating shaft 14. The rotating shaft 14 extends into the mixing tank 12. The stirring rods 15 are fixedly connected to the outside of the rotating shaft 14. A cleaning plate 16 is fixedly connected to the end of each stirring rod 15 away from the rotating shaft 14. A cleaning plate 16 is installed on the outside of the rotating shaft 14 near the bottom of the stirring rods 15. The mixing tank 12 is equipped with two scrapers 17. A discharge pipe 18 is provided on one side of the mixing tank 12. A discharge cylinder 19 is provided at the end of the discharge pipe 18 away from the mixing tank 12. The scrapers 17 are fixedly connected to the outside of the rotating shaft 14. One end of the discharge pipe 18 is fixedly connected to the inner wall of the slot opened on one side of the mixing tank 12. The other end of the discharge pipe 18 is fixedly connected to the inner wall of the slot opened on one side of the discharge cylinder 19. A second motor 110 is provided at the top of the discharge cylinder 19. A discharge paddle 111 is provided at the bottom of the second motor 110. A grouting head 112 is provided at the bottom of the discharge cylinder 19. The second motor 110 is fixedly installed at the top of the discharge cylinder 19. The output end of the second motor 110 is fixedly connected to the top of the discharge paddle 111. A grouting head 112 is fixedly installed at the bottom of the discharge cylinder 19. A feed inlet 32 ​​is provided at the top of the mixing tank 12. A cleaning mechanism 2 is provided on one side of the discharge cylinder 19 of the moving vehicle body 11.

[0025] In this embodiment, when the device is needed to repair cracks in the reservoir dam, the slurry can first be fed into the mixing tank 12 through the feed inlet 32. The first motor 13 is then started to drive the rotating shaft 14. As the shaft 14 rotates, the three stirring rods 15 stir the slurry in the tank, preventing it from becoming viscous and clumpy due to prolonged storage. This ensures smooth slurry feeding. Simultaneously, the cleaning plate 16 on one side of the stirring rods 15 scrapes off any slurry adhering to the inner wall of the mixing tank 12, preventing any residual granular slurry from being missed. The mixing process involves the rotating shaft 14 and the synchronous rotation of the scraper 17, which can stir the slurry at the bottom of the mixing tank 12. When the slurry is discharged from the discharge pipe 18, the rotating scraper 17 can push the slurry at the bottom of the mixing tank 12 to be discharged from the discharge pipe 18. The stirred slurry will enter the discharge cylinder 19 through the discharge pipe 18. The second motor 110 is started to drive the discharge paddle 111 to rotate. As the discharge paddle 111 rotates, the slurry will be transported and moved from top to bottom. Finally, the cracks in the reservoir dam are repaired through the grouting head 112.

[0026] like Figures 1-4 As shown, the cleaning mechanism 2 includes a support platform 21. One side of the support platform 21 is fixedly connected to one side of the mobile vehicle body 11. A water tank 22 is fixedly installed on the top of the support platform 21. A water pump 23 is fixedly installed on the bottom of the water tank 22. The input end of the water pump 23 extends into the water tank 22. The output end of the top of the water pump 23 is fixedly connected to one end of a water pipe 24. The other end of the water pipe 24 passes through the top of the mixing tank 12 and extends into the mixing tank 12.

[0027] In this embodiment, after the equipment is used, some slurry will remain in the mixing tank 12. In order to avoid the use of slurry in the future, the water pump 23 can be started to draw water from the water tank 22 into the water pipe 24. Finally, the water is sprayed into the mixing tank 12 through the water pipe 24 to wash the stirring rod 15 and the scraper 17. In addition, the rotating stirring rod 15 and the cleaning plate 16 can be used to scrub the inner wall of the mixing tank 12 to ensure that the inside of the mixing tank 12 is clean and hygienic.

[0028] This utility model provides a device for repairing cracks in a reservoir dam, the specific working principle of which is as follows:

[0029] When using this device to repair cracks in a reservoir dam, the slurry must first be fed into the mixing tank 12 through the feed inlet 32. The first motor 13 is started, driving the rotating shaft 14 to rotate. The three stirring rods 15 on the rotating shaft 14 then stir the slurry to prevent it from becoming viscous and clumping due to prolonged storage in the tank. The cleaning plate 16 on one side of the stirring rod 15 can scrape off the slurry adhering to the inner wall of the tank, preventing any granular slurry from remaining unstirred. As the rotating shaft 14 rotates, the scraper 17 rotates synchronously, stirring the slurry at the bottom of the mixing tank 12. When the slurry is discharged from the discharge pipe 18, the rotating scraper 17 pushes it out of the discharge pipe 18. The stirred slurry enters the discharge cylinder 19 through the discharge pipe 18. The second motor 110 is started, driving the discharge paddle 111 to rotate, and the slurry moves downwards accordingly. Finally, the grouting head 112 completes the repair of the cracks in the reservoir dam.

[0030] 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.
