Second, the walking mechanism has poor stability, easily slipping and jamming, affecting the continuity of cleaning. Third, the cleaning mechanism cannot adaptively adjust according to the degree of dirt accumulation and structural changes on the pipe wall, easily leading to incomplete cleaning or pipe damage. Fourth, it requires a high degree of manual intervention, is complex to operate, and poses safety hazards. Therefore, a drainage pipe wall cleaning device is needed. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3A drainage pipe wall cleaning device includes a drive pipe 1, a pipe traveling mechanism 2 is provided on the surface of the drive pipe 1, and a cleaning mechanism 3 is provided at the left end of the drive pipe 1. The pipe traveling mechanism 2 realizes the movement of the cleaning mechanism 3 inside the drainage pipe. The pipe traveling mechanism 2 includes a fixed seat 21. Six fixed seats 21 are arranged in groups of three. Two groups of fixed seats 21 are fixedly installed at the right end of the drive pipe 1, and each group of fixed seats 21 is arranged in a circular array. The two ends of the fixed seats 21 are rotatably connected to the first connecting rod 22 by a pin. One end of every four first connecting rods 22 is rotatably connected to the traveling mounting plate 23 by a pin. The opposing surfaces of the two traveling mounting plates 23 are rotatably connected to the auxiliary rotating wheel 24 by bearings. The arc surfaces of the multiple auxiliary rotating wheels 24 are driven by the traveling track 25. A drive motor 26 is also installed between the two traveling mounting plates 23. A drive gear 27 is installed at the output end of the drive motor 26. The teeth of the drive gear 27 mesh with the tooth grooves of the traveling track 25.

[0020] Specifically, this is achieved by setting up a pipe-walking mechanism 2, allowing the cleaning mechanism 3 to move freely inside the drain pipe, thus ensuring a wider cleaning range and more thorough cleaning, especially suitable for longer or more complex drain pipes. The meshing transmission design of the drive motor 26 and the walking track 25 provides a stable driving force, ensuring continuous operation of the device. This design allows the device to clean for extended periods without easily stopping or getting stuck, making it highly adaptable. Through the ring-array distribution of fixed seats 21, the first connecting rod 22, and their rotating connection design, the device can flexibly adapt to pipes of different diameters and shapes, enabling its application in various drain pipes and avoiding the disadvantages of overly complex or bulky structures.

[0021] A fixing ring 28 is fixedly installed on the arc surface of the left end of the drive tube 1. Guide rods 29 are installed on the opposite surfaces of the two fixing rings 28. The three guide rods 29 are arranged in a ring array on the surface of the drive tube 1. A sliding ring 210 is also slidably inserted into the arc surface of the drive tube 1. The arc surfaces of the three guide rods 29 are also slidably inserted into the surface of the sliding ring 210. The surface of the sliding ring 210 is rotatably connected to a second connecting rod 211 via a pin. One end of the second connecting rod 211 is slidably inserted into an adjusting tube 212. The arc surface of the second connecting rod 211 is also movably sleeved with a first spring 213. One end of the first spring 213 is in contact with the surface of the adjusting tube 212. One end of the second connecting rod 211 is slidably limited inside the adjusting tube 212 via a limiting rod in the limiting groove of the adjusting tube 212. One end of every two adjusting tubes 212 is rotatably connected to the surfaces of two opposite traveling mounting plates 23 via a pin.

[0022] Specifically, this is achieved through the coordinated design of the fixed ring 28, guide rod 29, sliding ring 210, second connecting rod 211, and adjusting pipe 212. This allows for precise adjustment of the cleaning device's operation, adapting to drainage pipes of different diameters and shapes. This adjustment mechanism enhances the equipment's flexibility, enabling it to operate efficiently in various pipe environments.

[0023] Two swing motors 214 are respectively installed on the top of one of the fixed bases 21 and on the surface of one of the adjusting tubes 212. The output end of the swing motor 214 is connected to a swing rod 215 through a coupling. One end of the swing rod 215 is rotatably connected to a Z-shaped rod 216. The other ends of the two Z-shaped rods 216 are respectively inserted into the surface of the first connecting rod 22 and the surface of the second connecting rod 211.

[0024] Specifically, this is achieved through the collaboration of the swing motor 214, the swing rod 215, and the Z-shaped rod 216, which allows the cleaning mechanism 3 to operate more flexibly during the cleaning process. By controlling the movement of the Z-shaped rod 216, the force and angle can be precisely adjusted. The linkage design between the swing motor 214 and the Z-shaped rod 216 enables automatic adjustment of the cleaning angle and direction, allowing the device to adapt to pipes of different shapes and sizes. This automated adjustment reduces manual intervention, improves operational accuracy, and ensures the uniformity of the cleaning effect.

[0025] A power module 217 is installed on the inner wall of the right end of the drive tube 1. The power module 217 is electrically connected to the drive motor 26 and the swing motor 214. A U-shaped tube 218 is also installed on the right end of the drive tube 1. A camera 219 is fixedly installed on one end of the U-shaped tube 218. The power module 217 is electrically connected to the camera 219. The power module 217, drive motor 26, swing motor 214 and camera 219 are all controlled by the control module.

[0026] Specifically, this is achieved by installing a camera 219 inside the U-shaped pipe 218, which allows for real-time monitoring of the cleaning process, observation of the pipe's interior, and helps operators understand the progress of the cleaning, promptly identifying and resolving any potential problems. This is especially important for complex pipes or hard-to-reach areas.

[0027] The cleaning mechanism 3 enables the pipe walking mechanism 2 to perform cleaning actions while moving inside the drain pipe. The cleaning mechanism 3 includes a cleaning wheel 31 and a cleaning cutter 32. A cleaning motor 33 is installed on the inner wall of the right end of the drive pipe 1. The cleaning motor 33 is powered and driven by the power module 217. An end head 34 is installed on the right end of the drive pipe 1 by screws. A cleaning shaft 35 is installed on the output end of the cleaning motor 33 through a coupling. One end of the cleaning shaft 35 passes through and extends to the left end of the end head 34. A triangular drive block 36 is fixedly installed on one end of the cleaning shaft 35. A mounting connecting rod 37 is installed on the left end of the triangular drive block 36. Multiple cleaning cutters 32 are installed in a ring array on the surface of the mounting connecting rod 37.

[0028] Specifically, the cleaning motor 33 and the swing motor 214 work together, using a control module to intelligently adjust the cleaning force and angle, automatically adapting to different pipe shapes and reducing manual intervention. A camera 219 provides real-time monitoring, further enhancing the system's automation capabilities. The combination of the cleaning motor 33, the cleaning shaft 35, and the triangular drive block 36 allows the device to perform more precise cleaning tasks in the pipes. Simultaneously, multiple cleaning cutters 32 are installed in a circular array, increasing the cleaning coverage and efficiency, ensuring a more thorough removal of dirt and deposits from the pipes.

[0029] The three end faces of the triangular drive block 36 are slidably connected to the limiting insertion shaft 38. One end of the limiting insertion shaft 38 is equipped with a fixed mounting shaft 39. Both ends of the fixed mounting shaft 39 are rotatably connected to the surface of the cleaning wheel 31 through bearings. The arc surface of the limiting insertion shaft 38 is also movably sleeved with a second spring 310. One end of the second spring 310 is installed on the surface of the triangular drive block 36, and the other end of the second spring 310 is installed on the stepped surface of the limiting insertion shaft 38.

[0030] Specifically, the introduction of the second spring 310 makes the entire cleaning system more flexible. Through the spring's cushioning effect, the device can better adapt to different surfaces and curvatures within the pipe, avoiding excessively violent collisions or damage. The spring also enhances the device's fault tolerance, ensuring stable operation even in complex pipe environments. Through the precise coordination of the triangular drive block 36, the cleaning cutter 32, and the cleaning wheel 31, the device can quickly and thoroughly clean scale or debris from the pipe while avoiding damage to the pipe itself.

[0031] Through the coordinated design of the pipe walking mechanism 2 and the cleaning mechanism 3, adaptive movement and efficient cleaning of the drainage pipe interior are achieved. The walking mechanism adopts a track drive and linkage adjustment structure, which can adapt to different pipe diameters and ensure stable movement without jamming; the cleaning mechanism 3 uses a combination of a ring array of cutting blades and elastic cleaning wheels 31 to achieve all-round cleaning without blind spots. Real-time monitoring by camera 219 and modular control improve operational accuracy and reduce manual intervention. The overall structure is highly flexible, with a wide cleaning coverage, effectively removing dirt deposits while avoiding pipe damage, making it suitable for efficient maintenance of complex or long-distance drainage pipes.

[0032] Working principle: The device achieves autonomous movement within the drainage pipe through a pipe-walking mechanism 2 on the surface of the drive pipe 1. In the walking mechanism, fixed seats 21 are arranged in a circular array and hinged to the walking mounting plate 23 via a first connecting rod 22, forming a telescopic and adjustable structure to adapt to different pipe diameters. The drive motor 26 drives the drive gear 27 to mesh with the walking track 25, providing stable power to the device and enabling it to continuously move forward or backward within the pipe.

[0033] When the device enters the area to be cleaned, the cleaning mechanism 3 is activated. The cleaning motor 33 drives the cleaning shaft 35 to rotate, which in turn drives the triangular drive block 36 to rotate. The triangular drive block 36 is connected to the cleaning wheel 31 via a limit insertion shaft 38 and a second spring 310, giving the cleaning wheel 31 elastic buffering capability to conform to changes in the inner wall of the pipe. The cleaning cutting blades 32, arranged in a ring array, rotate synchronously with the cleaning wheel 31 to scrape and cut away the dirt on the pipe wall.

[0034] During the cleaning process, the swing motor 214 adjusts the contact force of the walking track 25 according to the size of the inner wall of the drain pipe. The control module intelligently adjusts the cleaning intensity and path based on the real-time feedback of the pipe's inner wall condition from the camera 219, ensuring comprehensive coverage of pipes of different shapes and diameters. The entire system achieves efficient and adaptive cleaning of the drain pipe's inner wall through coordinated walking and cleaning, while avoiding damage to the pipe.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
