Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically a trenchless pipeline repair and cleaning robot. Background Technology

[0002] In urban underground pipeline systems, such as drainage pipes and gas pipelines, long-term use and various external factors can lead to the accumulation of large amounts of dirt, deposits, and even blockages. This not only affects the normal function of the pipelines but can also cause a series of safety hazards, such as urban flooding due to poor drainage and gas leaks caused by blocked gas pipelines.

[0003] Traditional pipe cleaning methods often require excavation to expose the pipes for cleaning and repair. However, excavation work not only severely impacts surface traffic and the surrounding environment but also consumes significant manpower, resources, and time, resulting in high costs.

[0004] With the development of technology, trenchless repair technology has gradually emerged, among which trenchless pipeline cleaning robots have become an important tool. However, currently available trenchless pipeline cleaning robots struggle to adaptively adjust their movement radius when facing adjacent pipes of different diameters, exhibiting poor adaptability. They cannot adaptively adjust their movement radius according to the changing pipe diameter, often failing to properly conform to the inner wall of the pipe for cleaning, resulting in unsatisfactory cleaning effects and failing to meet the needs of practical engineering projects. Therefore, developing a trenchless pipeline cleaning robot that can effectively solve the above problems is of significant practical importance. Utility Model Content

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] This utility model discloses a trenchless pipeline repair and cleaning robot.

[0039] Example 1

[0040] According to the appendix Figure 1-4 As shown, it includes a support rod 1 and a drive unit 2 and a cleaning unit 3 mounted thereon. The drive unit 2 includes:

[0041] Active component 21, which is used to drive the cleaning robot to move;

[0042] The adaptive adjustment component 22 is configured in two groups, and the two groups of adaptive adjustment components 22 are respectively arranged on both sides of the active component 21.

[0043] The adaptive adjustment component 22 includes:

[0044] Fixed seat 221 is fixedly sleeved on bearing rod 1;

[0045] Rotating rod 222, one end of which is rotatably connected to fixed base 221;

[0046] Telescopic mechanism 224 is connected to rotating rod 222. Telescopic mechanism 224 is used to adjust the unfolding angle of rotating rod 222 to adapt to pipe cleaning with changing diameter.

[0047] Furthermore, the active component 21 includes:

[0048] Movable rod 211, one end of movable rod 211 passes through bearing rod 1, and movable rod 211 is slidably connected to bearing rod 1;

[0049] Equipment box 212 is fixedly connected to the bottom of movable rod 211, and a drive motor is installed inside the equipment box 212;

[0050] The drive wheel 213 is fixedly connected to the output end of the drive motor. When the drive motor in the active assembly 21 is activated, it drives the drive wheel 213 to rotate. The friction generated by the contact between the drive wheel 213 and the inner wall of the pipe propels the entire cleaning robot to move within the pipe. The movable rod 211 can slide on the support rod 1 to adjust the position of the equipment box 212 and the drive wheel 213, ensuring that the drive wheel 213 always maintains good contact with the inner wall of the pipe and provides stable movement power.

[0051] Furthermore, the adaptive adjustment component 22 also includes a driven wheel 223, which is rotatably connected to the other end of the rotating rod 222.

[0052] Furthermore, a slider 2221 is slidably connected to the inner side of the rotating rod 222.

[0053] Furthermore, the telescopic mechanism 224 includes:

[0054] Sleeve seat 2241;

[0055] Telescopic rod 2242, one end of which is slidably connected to sleeve seat 2241;

[0056] Spring 2243 is sleeved on the outside of telescopic rod 2242, and one end of spring 2243 is fixedly connected to sleeve seat 2241;

[0057] Connecting block 2244 is fixedly connected to the other end of telescopic rod 2242, and connecting block 2244 is fixedly connected to the other end of spring 2243.

[0058] Furthermore, the bottom end of the sleeve seat 2241 is rotatably connected to the bearing rod 1.

[0059] Furthermore, the connecting block 2244 is rotatably connected to the slider 2221. When the cleaning robot enters pipes of different diameters, the adaptive adjustment component 22 begins to function. The spring 2243 in the telescopic mechanism 224 automatically adjusts the position of the telescopic rod 2242 within the sleeve seat 2241 according to the pressure on the inner wall of the pipe. When the pipe diameter decreases, the inner wall of the pipe exerts inward pressure on the driven wheel 223, pushing the rotating rod 222 to rotate inward, while the telescopic rod 2242 contracts within the sleeve seat 2241, compressing the spring 2243; when the pipe diameter increases, the elastic force of the spring 2243 pushes the telescopic rod 2242 outward, causing the rotating rod 222 to unfold outward, while the driven wheel 223 remains firmly against the inner wall of the pipe. The slider 2221 on the inner side of the rotating rod 222 is rotatably connected to the connecting block 2244, ensuring the flexibility of the rotating rod 222 during rotation and making the adaptive adjustment process smoother.

[0060] Example 2

[0061] According to the appendix Figure 1-4 As shown, it includes a support rod 1 and a drive unit 2 and a cleaning unit 3 mounted thereon. The drive unit 2 includes:

[0062] Active component 21, which is used to drive the cleaning robot to move;

[0063] The adaptive adjustment component 22 is configured in two groups, and the two groups of adaptive adjustment components 22 are respectively arranged on both sides of the active component 21.

[0064] The adaptive adjustment component 22 includes:

[0065] Fixed seat 221 is fixedly sleeved on bearing rod 1;

[0066] Rotating rod 222, one end of which is rotatably connected to fixed base 221;

[0067] Telescopic mechanism 224 is connected to rotating rod 222. Telescopic mechanism 224 is used to adjust the unfolding angle of rotating rod 222 to adapt to pipe cleaning with changing diameter.

[0068] Furthermore, the cleaning unit 3 includes:

[0069] The cleaning brush 31 is set at one end of the support rod 1. The end of the support rod 1 is provided with a drive structure and a water spraying mechanism. The drive structure is connected to the cleaning brush 31. The drive structure is used to drive the cleaning brush 31 to rotate, and the water spraying mechanism is used to rinse the inner wall of the pipe.

[0070] A flexible scraper 32 is positioned inside the cleaning brush 31. Made of a plastic material, the scraper 32 can expand and contract according to the pipe diameter to ensure a tight fit. The cleaning unit 3 begins operation as the cleaning robot moves. The cleaning brush 31 is located at one end of the support rod 1. As the robot moves, the cleaning brush 31 rotates and cleans the inner wall of the pipe, brushing off surface dirt and deposits. The flexible scraper 32, positioned inside the cleaning brush 31, further scrapes away residual dirt from the inner wall of the pipe after the initial cleaning by the cleaning brush 31, ensuring the cleanliness of the inner wall. Through the synergistic action of the cleaning brush 31 and the flexible scraper 32, efficient cleaning of the inner wall of the pipe is achieved.
