[0029] Referring to Figures 1 to 4The utility model provides a kind of cleaning module of pipeline inspection robot in some embodiments of the utility model, and pipeline inspection robot further includes driving wheel and driven wheel, and it includes driving wheel brush assembly 1 and driven wheel brush assembly 2.The driving wheel brush assembly 1 includes driving connection rod 11 connected with driving wheel, driving positioning rod 12 movably connected with driving connection rod 11, multiple drive fixed parts 13 hinged with driving positioning rod 12, driving wheel brush head 14 connected with drive fixed part 13 and driving elastic member 15, one end of driving elastic member 15 is connected to driving connection rod 11, the other end of driving elastic member 15 is connected to driving positioning rod 12.The driven wheel brush assembly 2 includes driven connection rod 21 connected with driven wheel, driven positioning rod 22 movably connected with driven connection rod 21, driven wheel brush head 23 connected with driven positioning rod 22 and driven elastic member 24, one end of driven elastic member 24 is connected to driven connection rod 21, the other end of driven elastic member 24 is connected to driven positioning rod 22.Wherein, the rotational speed of the driving wheel is controlled by the chassis drive motor of pipeline inspection robot, and the cleaning strength of driving wheel brush head 14 and driven wheel brush head 23 can be adjusted as required.Driving positioning rod 12 can be telescopic along the axial direction of driving connection rod 11 to change the extension length of driving wheel brush head 14, and driven positioning rod 22 can be telescopic along the axial direction of driven connection rod 21 to change the extension length of driven wheel brush head 23.In addition, the driving elastic member 15 and the driven elastic member 24 are preferably springs.

[0030] Understandably, the cleaning module of pipeline inspection robot is connected with driving wheel by driving wheel brush assembly 1, which can rotate with the rotation of driving wheel, and driven wheel brush assembly 2 is connected with driven wheel, which can rotate with the rotation of driven wheel.Driving wheel and driven wheel of pipeline inspection robot drive driving wheel brush head 14 and driven wheel brush head 23 respectively to clean pipeline.The setting of driving elastic member 15 and driven elastic member 24 and the hinging of multiple drive fixed parts 13 to driving positioning rod 12 enable the cleaning module to adjust the extension length of driving wheel brush head 14 and driven wheel brush head 23 according to the width of pipeline to better adapt to the cleaning of pipeline with different diameters, and driving elastic member 15 and driven elastic member 24 also provide driving wheel brush head 14 and driven wheel brush head 23 with a pushing force to increase the friction between driving wheel brush head 14 and driven wheel brush head 23 and pipe wall, so as to achieve better cleaning effect, and driving elastic member 15 and driven elastic member 24 enable driving wheel brush head 14 and driven wheel brush head 23 to automatically adjust posture when encountering curved pipeline or obstacles, so as to maintain good contact with inner wall of pipeline, enabling the cleaning module to work flexibly in pipeline with different diameters and shapes, improving cleaning efficiency and applicability, improving cleaning coverage, and effectively treating dirt in complex pipeline.

[0031] As Figure 1As shown, there are three drive fixing members 13 and three drive wheel brush heads 14, which are evenly arranged about the central axis of the drive positioning rod 12. Each drive wheel brush head 14 is cylindrical. Because multiple drive fixing members 13 are hinged to the drive positioning rod 12 and a drive elastic member is provided, the drive positioning rod 12 can extend and retract along the axial direction of the drive connecting rod 11, changing the extension length of the drive wheel brush head 14 and the tilt angle of the three drive wheel brush heads 14 relative to the drive connecting rod 11. The cleaning range of the three drive wheel brush heads 14 can vary according to different pipe sizes. When the cleaning range needs to be expanded, the drive wheel can be moved closer to the inner wall of the pipe; when the cleaning range needs to be reduced, the drive wheel can be moved away from the outer wall of the pipe, making the cleaning range quite flexible. Furthermore, when the drive wheel brush head 14 moves to its limit position, it is also subjected to the elastic force provided by the drive elastic member and the reaction force of the pipe wall, thus better cleaning the corners of the pipe. In some other embodiments, the number of the drive fixing member 13 and the drive wheel brush head 14 can be adjusted according to actual needs, and no specific limitation is made here.

[0032] Preferably, the bristles of the drive wheel brush head 14 are PBT bristles. These PBT bristles are resistant to high temperatures and chemical corrosion, have high toughness, are easy to process, have strong cleaning power, and are durable. They also have high hardness and rigidity, making them suitable for treating stubborn dirt on the inner walls of pipes. PBT bristles can effectively remove strongly adhering deposits through mechanical scraping.

[0033] like Figure 3 As shown, the driven wheel brush head 23 includes a cleaning disc 231 connected to the driven positioning rod 22, an inner brush head 232, and an outer brush head 233. Both the inner brush head 232 and the outer brush head 233 are connected to the cleaning disc 231. The outer brush head 233 is located outside the inner brush head 232. The bristles of the inner brush head 232 are made of PBT bristles. PBT material has high hardness and rigidity, making it suitable for treating stubborn dirt on the inner wall of pipes. PBT bristles can effectively remove strongly adhering deposits through mechanical scraping. The bristles of the inner brush head 232 are made of nylon bristles. Nylon material has good wear resistance and fatigue resistance, and can maintain stable performance during long-term operation. Nylon bristles can cover a wider cleaning area while reducing wear and extending service life.

[0034] Furthermore, the active connecting rod 11 is provided with an active guide groove 111, and the active positioning rod 12 is provided with an active protrusion 121 that matches the active guide groove 111, so as to realize the movable connection between the active connecting rod 11 and the active positioning rod 12. The driven connecting rod 21 is provided with a driven guide groove 211, and the driven positioning rod 22 is provided with a driven protrusion 221 that matches the driven guide groove 211, so as to realize the movable connection between the driven connecting rod 21 and the driven positioning rod 22.

[0035] In general, the cleaning module of the pipeline inspection robot can deal with different types of dirt by selecting different materials and combining multiple mechanical rotation modes. By setting elastic members and using an optimized mechanical structure, the cleaning module can adjust the cleaning strength and range according to the internal conditions of the pipeline. At the same time, the power source is the chassis of the pipeline inspection robot, which does not need to be charged separately, is convenient and energy-saving, and ensures stable operation for a long time.

[0036] It can be understood that the above embodiments only express the preferred embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application; It should be pointed out that for ordinary skilled in the art, the above technical features can be freely combined without departing from the concept of the present application, and a number of modifications and improvements can be made, which belong to the protection scope of the present application; Therefore, any equivalent transformation and modification within the scope of the claims of the present application shall belong to the scope of the claims of the present application.
