Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline maintenance robots, and more particularly relates to a cleaning structure of a pipeline maintenance robot's visual unit. Background Art

[0002] In pipeline maintenance operations, real-time monitoring of the pipeline interior is crucial for accurately determining pipeline conditions and performing effective maintenance. However, existing pipeline maintenance robot monitoring systems have many shortcomings.

[0003] Traditional pipeline monitoring components often lack effective cleaning devices. When the surface of the monitoring component is contaminated by foreign matter in the pipeline, it cannot be cleaned in time, resulting in blurred monitoring images or even inability to capture, affecting the accurate judgment of the internal situation of the pipeline.

[0004] Moreover, the installation and fixing method of the monitoring components is not stable enough, and it is easy to shake during the movement of the pipeline maintenance robot, resulting in unstable and unclear shooting images, affecting the monitoring effect and maintenance decisions.

[0005] In addition, when cleaning the monitoring component lens, the existing cleaning device has the problems of limited cleaning range and cleaning dead angles, and cannot completely and effectively remove the dirt on the lens, making it difficult to ensure the clarity of the monitoring component's shooting.

[0006] At the same time, the cleaning device is not adaptable enough to the shape of the monitoring component lens and cannot completely fit the lens surface for cleaning, resulting in unsatisfactory cleaning effect and failure to fully restore the shooting performance of the monitoring component. Summary of the Invention

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the monitoring component can perform real-time video monitoring of the inside of the pipeline. At the same time, the LED light groups on the upper and lower sides of the monitoring component can provide lighting, so that external users can see the inside of the pipeline clearly. When the surface of the monitoring component is contaminated by foreign matter in the pipeline, the two motors are started, and the two motors drive the threaded screws to rotate. The two threaded screws drive the two sliding frames to move upward through the two L-shaped slides. The two sliding frames drive the cleaning rollers to move upward. The cleaning rollers move upward to wipe the dirt on the surface of the monitoring component. By arranging a cleaning roller on the front side of the monitoring component, the monitoring component can be cleaned at any time, effectively avoiding the monitoring component from being unable to continue shooting due to dirt in the pipeline, and at the same time, the shooting clarity of the monitoring component can be improved.

[0014] The L-shaped guide rails are used to move the cleaning rollers up and down to clean the lens of the monitoring component. When the L-shaped guide rails move up to the top of the L-shaped guide rails, the cleaning rollers move down again, and the cleaning rollers can move up and down to clean the lens of the monitoring component. The cleaning rollers can move up and down to clean the lens of the monitoring component. The cleaning range is wide, the blind spots for cleaning are reduced, and the clarity of the monitoring component shots is improved.

[0015] In the present invention, when the cleaning roller moves, it will change its front and rear positions according to the lens housing of the monitoring component. When the cleaning roller moves from the lowest point of the monitoring component lens to the most convex point, the cleaning roller will drive the sliding frames on both sides to move outward, and the two sliding frames move outward to drive the supporting slides to slide outward. The two supporting slides slide inside the two L-shaped slides. When the cleaning roller moves from the most convex point of the monitoring component to the lowest point, the two springs will drive the cleaning roller to slide inward through elastic force, so that the cleaning roller can completely fit the lens of the monitoring component, and can more completely clean the monitoring component lens, thereby further improving the cleaning ability of the lens.

[0019] See also Figure 1-Figure 7 The present invention provides a cleaning structure of a visual unit of a pipeline maintenance robot, including a pipeline maintenance robot 1. The outer ring of the pipeline maintenance robot 1 is provided with three driving wheel groups 11. An expansion rod 12 is fixedly installed at the end of the pipeline maintenance robot 1. The surface of the expansion rod 12 is provided with an expansion frame 13. The side wall of the expansion frame 13 is provided with a threaded rod 16. Two fixed brackets 19 are provided at the end of the threaded rod 16. A monitoring component 22 is provided between the two fixed brackets 19. L-shaped slides 28 are installed inside the two fixed brackets 19. The monitoring component 22 can perform real-time video monitoring of the inside of the pipeline. At the same time, the LED light groups 23 on the upper and lower sides of the monitoring component 22 can provide lighting, so that external users can see the inside of the pipeline clearly. When the surface of the monitoring component 22 is contaminated by foreign matter in the pipeline, When the cleaning roller 32 is moved upward, the cleaning roller 32 wipes the dirt on the surface of the monitoring component 22 clean. A cleaning roller 32 is installed between the ends of the two L-shaped slides 28. Expansion grooves 14 are opened on the left and right sides of the expansion frame 13. Two fixing bolts 15 are installed inside the expansion frame 13 at the opening of the expansion groove 14. The threaded rod 16 is inserted into the expansion groove 14. The surface of the threaded rod 16 on the back of the expansion frame 13 is threadedly installed with a screw sleeve 17. The end of the threaded rod 16 is fixedly installed with a fixing plate 18. Two fixing brackets 19 are fixedly connected to the end of the fixing plate 18.

[0020] The motor 2 is fixedly installed on the inner wall of the fixed bracket 19 on the left side of the monitoring component 22, and the transmission rod 21 is fixedly installed on the end of the output shaft of the motor 2, and the transmission rod 21 is rotatably connected to the fixed bracket 19 on the other side. Then the threaded rod 16 is inserted into the expansion slot 14, and the threaded rod 16 is clamped by the fixing bolt 15, and then the screw sleeve 17 is rotated and clamped again, using double fixation to improve the stability of the monitoring component 22 and the clarity of the shooting picture when the pipeline maintenance robot 1 moves, and reduce the shaking caused by unstable structural connection. The monitoring component 22 is fixedly sleeved outside the transmission rod 21, and the upper and lower ends of the monitoring component 22 are fixedly installed with LED light groups 23. The side walls of the two fixed brackets 19 are provided with L-shaped slide rails 25, and the two L-shaped slides 28 slide vertically inside the L-shaped slide rails 25.

[0021] A motor 27 is fixedly installed on the top of the two L-shaped slide rails 25, and a threaded screw 26 is fixedly installed on the end of the output shaft of each motor 27, and the threaded screw 26 is rotatably connected to the bottom of the L-shaped slide rail 25. Each threaded screw 26 passes through the L-shaped slide 28 and cooperates with the L-shaped slide 28 through a thread. A rotating frame 33 is fixedly installed inside the cleaning roller 32. The two threaded screws 26 drive the L-shaped slide 28 to move upward through the thread. The two L-shaped slides 28 move upward inside the L-shaped slide rail 25, and the two L-shaped slides 28 move upward to drive the L-shaped slide 28 to move upward. The two sliding frames 3 move upward, and the two sliding frames 3 move upward to drive the cleaning roller 32 to move upward through the rotating frame 33. The cleaning roller 32 moves upward and contacts the lens of the monitoring component 22. When the L-shaped slide 28 moves upward to the top of the L-shaped slide rail 25, it moves down again. The sliding frames 3 are rotatably installed on the left and right ends of the rotating frame 33. The side walls of the two sliding frames 3 are fixedly installed with supporting slides 31. Each supporting slide 31 is slidably inserted into the L-shaped slide 28, and a spring 29 is fixedly installed between the end of each supporting slide 31 and the inner wall of the L-shaped slide 28.

[0022] Working principle: The first step is to put the pipeline maintenance robot 1 into the pipeline. The three driving wheel groups 11 on the outer ring of the pipeline maintenance robot 1 can drive the pipeline maintenance robot 1 to move in the pipeline. When the pipeline maintenance robot 1 moves in the pipeline, the monitoring component 22 can perform real-time video monitoring of the inside of the pipeline. At the same time, the LED light groups 23 on the upper and lower sides of the monitoring component 22 can provide lighting, so that external users can see the inside of the pipeline clearly. When the surface of the monitoring component 22 is contaminated by foreign matter in the pipeline, the two motors 27 are started. The two motors 27 drive the threaded screws 26 to rotate. The two threaded screws 26 drive the two sliding frames 3 to move upward through the two L-shaped slides 28. The two sliding frames 3 drive the cleaning rollers 32 to move upward. The cleaning rollers 32 move upward to wipe the dirt on the surface of the monitoring component 22. By arranging the cleaning rollers 32 on the front side of the monitoring component 22, the monitoring component 22 can be cleaned at any time, effectively preventing the monitoring component 22 from being unable to continue shooting due to dirt in the pipeline, and at the same time improving the shooting clarity of the monitoring component 22.

[0023] In the second step, when installing the fixing plate 18, first rotate the screw sleeve 17 away from the threaded rod 16, then insert the threaded rod 16 into the expansion slot 14, clamp the threaded rod 16 with the fixing bolt 15, and then rotate the screw sleeve 17 to clamp it again, using double fixation to improve the stability of the monitoring component 22 and the clarity of the shooting image when the pipeline maintenance robot 1 moves, and reduce the shaking caused by unstable structural connection.

[0024] In the third step, when the lens of the monitoring component 22 is dirty, the two motors 27 are started. The two motors 27 drive the two threaded screws 26 to rotate through the output shafts. The two threaded screws 26 drive the L-shaped slide 28 to move upward through the threads. The two L-shaped slides 28 both move upward inside the L-shaped slide rail 25. The two L-shaped slides 28 move upward and drive the two sliding frames 3 to move upward. The two sliding frames 3 move upward and drive the cleaning roller 32 to move upward through the rotating frame 33. The cleaning roller 32 moves upward and contacts the lens of the monitoring component 22. When the L-shaped slide 28 moves upward to the top of the L-shaped slide rail 25, it moves down again. In this reciprocating manner, the cleaning roller 32 can move up and down to clean the lens of the monitoring component 22. The cleaning range is wide, the blind spots of cleaning are reduced, and the clarity of the photos taken by the monitoring component 22 is improved. Since the lens housing of the monitoring component 22 is mostly spherical, the cleaning roller 32 will change its front and rear position according to the lens housing of the monitoring component 22 when it moves. When the cleaning roller 32 moves from the lowest point of the lens of the monitoring component 22 to the most convex point, the cleaning roller 32 will drive the sliding frames 3 on both sides to move outward. The outward movement of the two sliding frames 3 drives the supporting slides 31 to slide outward, and the two supporting slides 31 slide inside the two L-shaped slides 28. When the cleaning roller 32 moves from the most convex point of the monitoring component 22 to the lowest point, the two springs 29 will drive the cleaning roller 32 to slide inward through elastic force, so that the cleaning roller 32 can completely fit the lens of the monitoring component 22, and can more completely clean the lens of the monitoring component 22, further improving the cleaning ability of the lens.
