Description

Technical Field

[0001] This invention relates to the field of tunnel light cleaning technology, specifically a modular tunnel light non-marking cleaning device. Background Technology

[0002] Tunnel lighting systems operate under harsh conditions of high dust and high humidity for extended periods. Dust, oil, and condensation easily accumulate on the surfaces of the lamps, leading to a significant decrease in light transmittance and lighting efficiency, and potentially causing safety hazards. Traditional manual cleaning methods suffer from low efficiency, high maintenance costs, and high risks associated with working at heights, making them unsuitable for the needs of modern tunnel operation and maintenance. In recent years, automatic cleaning technology has become a key focus of industry research and development.

[0003] Existing street light cleaning devices typically use track-mounted robotic arms or integrated cleaning trolleys to clean the lights. However, these devices lack adaptability to different tunnel structures and light types, and have limited versatility. Therefore, it is necessary to develop a cleaning device that can improve cleaning efficiency while effectively protecting against splashes and adapting to multiple scenarios.

[0004] The inventors of this application discovered in their research that the core defect of the aforementioned prior art is that water droplets splash during the cleaning process, which can easily affect traffic and tunnel walls. Summary of the Invention

[0022] Please see the appendix Figure 1 -Appendix Figure 7 This invention provides a modular tunnel light traceless cleaning device, including a track 1. The track 1 is fixedly connected to a traveling vehicle body 2 via a load-bearing wheel 21 and a first connecting member 23. The top of the first connecting member 23 is rotatably connected to the load-bearing wheel 21 and the guide wheel 22.

The output end of the rotating motor 53 is fixedly connected to a third connector 51, which is externally fixedly connected to a windproof cover 64.

[0025] Specifically, the three-degree-of-freedom adjustment mechanism uses a lead screw lifting arm 4 to adjust the vertical movement of the Z-axis. The lead screw lifting arm 4 is fixed below the front and rear adjusting lead screw module 3 via a fixed base 41. The fixed base 41 connects the servo motor 42 of the lead screw lifting arm 4 to the first arm 44. Both the servo motor 42 and the first arm 44 are vertically downward. A third support base 43 is installed on the first arm 44, and a first modified lead screw 45 is installed on the third support base 43. The surface of the first modified lead screw 45 has a second groove 451. The second modified lead screw 48 is hollow and has a keyway 481 inside. The keyway 481 and the second groove 451 cooperate to allow both lead screws to rotate simultaneously. The first arm 44 has a first groove 441, and the second arm 47 also has a third groove 471. The protrusion on the back of the first groove 441 cooperates with the third groove 471 to install the first arm 44 and the second arm 47.

The fourth groove 491 is installed in conjunction with the protrusion on the back of the third groove 471. This design allows the first modified screw 45 to rotate, thereby driving the second nut seat 46 to move and the second modified screw 48 to rotate. The second nut seat 46 drives the second arm 47 and the second modified screw 48 to move. The rotation of the second modified screw 48 drives the third nut seat 461 to move, thereby driving the third arm 49 to move. That is, when the motor rotates, the second arm 47 and the third arm 49 move downward or upward at the same time. The end rotation angle component 5 is installed below the third arm 49 to complete the adjustment of the degree of freedom of movement in the Z-axis direction. The three-degree-of-freedom adjustment mechanism adjusts the rotational degree of freedom of the X-axis through the end rotation angle component 5. The third arm 49 is fixedly installed with the fixed housing 52. The fixed housing 52 is equipped with a rotary motor 53. The rotary motor 53 is fixedly installed with the third connecting piece 51. The third connecting piece 51 is fixedly connected with the windproof cover 64. The end cleaning module 6 is fixed on the third connecting piece 51. The rotation of the rotary motor 53 drives the third connecting piece 51 to rotate, thereby driving the end cleaning module 6 to rotate, thus completing the adjustment of the rotational degree of freedom in the X-axis direction. By adjusting these three degrees of freedom, the device can be better adapted to different lamps and their installation locations.
