[0002] In various fields such as urban infrastructure maintenance and environmental protection, the condition monitoring and maintenance of pipeline systems are of paramount importance. To ensure the safe and stable operation of pipelines, which plays a decisive role in ensuring the orderly conduct of social production and life, portable pipeline inspection instruments have become an important tool for pipeline maintenance and inspection because they can carry out inspection work quickly and efficiently on site.

[0003] This instrument uses a probe that can extend into the pipe and is moved inside by a cable to allow for direct inspection of the pipe's inner wall. These instruments are typically equipped with high-definition cameras and sensors, enabling real-time acquisition of images and data from inside the pipe, providing pipeline maintenance personnel with intuitive and accurate diagnostic information.

[0004] However, during pipeline inspection, the probe moves inside the pipeline, and the cable connected to its tail rubs against the inner wall of the pipeline, deposits, or other obstacles, causing the cable surface to become contaminated with dirt and other pollutants. This requires additional manual wiping, increasing physical exertion and reducing the overall efficiency of the inspection work. To address this issue, a portable pipeline inspection instrument is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a portable pipeline inspection instrument, which aims to improve the problem in the prior art that "the cable connected to the inspection probe follows the probe into the pipeline, causing the cable surface to be contaminated with dirt and other pollutants, which increases physical labor consumption through manual cleaning".

[0011] As a further description of the above technical solution:

[0012] Both gear one and gear two are positioned between positioning plate two and positioning plate one, and the positioning rod passes through positioning plate two and positioning plate one and is rotatably connected to the top of the support plate.

[0013] As a further description of the above technical solution:

[0014] Both sets of rotating wheels are arranged between the positioning plate and the support plate. The inner wall of the rotating wheels is fixedly connected with bristles, and multiple sets are arranged in a circular array with the center line of the rotating wheels as the center.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a portable pipeline inspection instrument, including a bracket 1 on which the pipeline inspection instrument is mounted. The bracket 1 allows for convenient carrying and movement of the instrument, and the instrument can be moved and inspected by simply lifting the bracket 1. The bracket 1 contains a cable 4 for connecting a probe to inspect the pipeline. A cleaning assembly for cleaning the cable 4 is located at the front of the bracket 1. The cleaning assembly includes a mounting frame 2 fixedly connected to the front of the bracket 1, providing support. A positioning plate 28 supporting a servo motor 21 is fixedly connected to the middle of the mounting frame 2, and a servo motor 21 driving a transmission rod 210 is fixedly mounted at the top of the positioning plate 28.

[0032] Furthermore, a positioning plate 27 is fixedly connected to the middle of the mounting frame 2 below the positioning plate 28 to increase stability and support gears 22 and 23. A transmission rod 210 is fixedly connected to the bottom end of the output shaft of the servo motor 21 to drive gears 22 and rotating wheels 26 to rotate. Gear 22 is fixedly connected to the outer wall of the transmission rod 210 to drive gear 23 to rotate. A support plate 25 is fixedly connected to the middle of the mounting frame 2 below the positioning plate 27 to provide support. Gear 23 is meshed on the right side of gear 22 to drive positioning rod 24 to rotate. A positioning rod 24 is fixedly connected through the middle of gear 23 to drive another set of rotating wheels 26 to rotate. Rotating wheels 26 that drive multiple sets of brush bristles 29 to rotate are fixedly connected to the outer walls of both the transmission rod 210 and the positioning rod 24.

[0033] Reference Figure 2 , Figure 3 and Figure 4 The inner left side of the rotating wheel 26 is provided with a scraping component that can additionally clean the bristles 29. The scraping component includes a scraper 3 that provides support and is fixedly connected to the inner left side of the mounting bracket 2.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The transmission rod 210 passes through the second positioning plate 28 and the first positioning plate 27 and is rotatably connected to the top of the support plate 25. The top of the transmission rod 210 is connected to the output shaft of the servo motor 21, and the bottom is rotatably connected to the top of the support plate 25. The mounting bracket 2 is set in an L shape and is fixedly connected to the upper front end and the bottom end of the bracket 1 respectively. By setting it in an L shape, it can be connected to the front of the bracket 1, and at the same time, it can increase the stability of the bracket 1. Gear 1 22 and gear 23 are both set between the second positioning plate 28 and the first positioning plate 27. The positioning rod 24 passes through the second positioning plate 28 and the first positioning plate 27 and is rotatably connected to the top of the support plate 25. Two sets of rotating wheels 26 are both set between the first positioning plate 27 and the support plate 25.

[0035] Furthermore, the inner wall of the rotating wheel 26 is fixedly connected with bristles 29, and multiple sets are arranged in a circular array with the center line of the rotating wheel 26 as the center. By setting multiple sets of bristles 29, when the cable 4 is wound up, the contaminants attached to the outer wall of the cable 4 can be cleaned by rotating the bristles 29. The rotating wheel 26 is set in an inwardly concave circular pulley shape, which facilitates the winding up of the cable 4.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The scraper 3 is located on the left inner wall of the rotating wheel 26 between the positioning plate 27 and the support plate 25. The right side of the scraper 3 is provided with a V-shaped groove 31 corresponding to the bristles 29. The V-shaped groove 31 is set in a V shape. By setting the V-shaped groove 31, when the bristles 29 rotate and come into contact with the inner wall of the V shape, the bristles 29 can be clamped by the V shape, thereby scraping off the contaminants on the bristles 29.

[0037] Working principle: When using this portable pipeline inspection instrument, the staff can easily carry the entire pipeline inspection instrument installed on the bracket 1 to the pipeline inspection site by hand. During the inspection operation, the connecting probe is passed between the two sets of rotating wheels 26. At this time, the cable 4 connecting the probe will go deep into the pipeline along with the probe. After the inspection is completed, the cable 4 is put away.

[0038] At this time, the servo motor 21 installed on the top of the positioning plate 28 is started. The output shaft of the servo motor 21 rotates, which drives the transmission rod 210 fixedly connected to it to rotate. The gear 22 fixed on the outer wall of the transmission rod 210 rotates accordingly. Since the gear 22 meshes with the gear 23, the gear 23 will be driven to rotate in the opposite direction. The positioning rod 24 is fixedly connected through the middle of the gear 23, so the positioning rod 24 will also rotate with the gear 23.

[0039] Rotating wheels 26 are fixedly connected to the outer walls of both the transmission rod 210 and the positioning rod 24. As the transmission rod 210 and the positioning rod 24 rotate, the two sets of rotating wheels 26 will rotate in opposite directions. Multiple sets of bristles 29 are arranged in a circular array with their center line as the center on the inner wall of the rotating wheels 26. When the rotating wheels 26 rotate, the multiple sets of bristles 29 will also rotate in opposite directions. When the cable 4 is passed between the two sets of rotating wheels 26, the rotating bristles 29 can contact the outer wall of the cable 4 during the winding process, thereby sweeping away the dirt and other contaminants attached to the outer wall of the cable 4 without the need for manual wiping.

[0040] During the cleaning process of the bristles 29 on the cable 4, some contaminants will also adhere to them. When the bristles 29 rotate to the left side with the rotating wheel 26, they will come into contact with the scraper 3 fixed on the inner wall of the left side of the mounting bracket 2. The scraper 3 has a V-shaped groove 31 on the right side corresponding to the bristles 29. When the bristles 29 rotate into the V-shaped groove 31, the V-shaped inner wall of the V-shaped groove 31 will clamp and squeeze the bristles 29, thereby scraping off the contaminants attached to the bristles 29, ensuring the cleaning effect of the bristles 29, so as to continuously and efficiently clean the cable 4 in the future, improve the overall efficiency of the inspection work, and reduce labor costs.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
