[0019] Please refer to Figures 1-4. This utility model provides a technical solution: Embodiment

[0020] Regarding the aforementioned problems, existing gantry-type cleaning equipment suffers from complex structure, inflexible movement, and difficulty in adapting to photovoltaic panels of different specifications.

[0021] The solution is as follows: A photovoltaic cleaning robot based on a gantry structure includes a device body 1. The device body 1 includes a movable seat device 2, a support frame device 3, a connecting crossbeam 4, a lifting structure 5, and a cleaning device 6. Each movable seat device 2 and support frame device 3 is provided in a set, with the set of movable seat devices 2 distributed laterally at equal intervals. A set of support frame devices 3 is installed on top of the movable seat devices 2. The connecting crossbeam 4 is installed between the sets of support frame devices 3. A set of lifting structures 5 is provided, with each set of lifting structures 5 installed inside the set of support frame devices 3. The cleaning device 6 is installed between the sets of lifting structures 5. The lifting structure 5 includes a follower slide rail 7 and a synchronous belt device 8, with the synchronous belt device 8 installed on the follower slide rail 7. The cleaning device 6 includes sliding wheels 9, a roller brush cover 10, a cleaning motor transmission assembly 11, and a rotating shaft mounting block 12. A set of sliding wheels 9 is provided, and both ends of the roller brush cover 10 are connected to a set of sliding wheels 9 via the rotating shaft mounting block 12. The cleaning motor transmission assembly... Component 11 is installed on the right end of the roller brush cover 10. The roller brush cover 10 is equipped with a drive rod 13. The drive end of the cleaning motor transmission assembly 11 is connected to one end of the drive rod 13. The surface of the drive rod 13 is provided with several sets of cleaning brushes 14 distributed in a horizontally equidistant manner. When adjusting the angle of the cleaning device 6, the operator starts the synchronous belt device 8 in the follower slide rail 7. The synchronous belt device 8 drives the sliding wheel 9 to move up or down in the follower slide rail 7. The sliding wheel 9 is installed with the roller brush cover 10 through the rotating shaft mounting block 12, so that one end of the sliding wheel 9 moves upward, and the sliding wheel 9 can rotate with the roller brush cover 10 (similar to the principle of a hinge). After adjusting the position of a set of sliding wheels 9, the cleaning device 6 can be tilted to fit against the photovoltaic panel. When cleaning the photovoltaic panel, the operator starts the cleaning motor transmission assembly 11. The drive end of the cleaning motor transmission assembly 11 drives the drive rod 13 to rotate, and then the cleaning brushes 14 on the drive rod 13 can clean the dust on the photovoltaic panel by rotating.

[0022] The support frame device 3 includes a bottom frame 15 and a support frame 16. The support frame 16 and the bottom frame 15 are smoothly transitioned and integrally processed. Both the bottom frame 15 and the support frame 16 are trapezoidal structures. The support frame 16 has several sets of fixed columns 17 arranged in a row at equal intervals. The bottom frame 15 has an installation box 18 installed inside. The support frame device 3 composed of the bottom frame 15 and the support frame 16 has high stability and can effectively improve the overall structural strength and stability. In addition, the space inside the bottom frame 15 can facilitate the installation and storage of the installation box 18.

[0023] The movable seat device 2 includes a base beam 19, an adjusting wheel device 20, and shock-absorbing springs 21. The base beam 19 has a T-shaped structure. There is one set of adjusting wheel devices 20, which are symmetrically installed at the bottom of the base beam 19. There are two sets of shock-absorbing springs 21, which are installed at an angle between the base beam 19 and the bottom frame 15. The top of the base beam 19 is provided with a shock-absorbing movable block 22. During shock absorption, the bottom frame 15 can tilt forward slightly through the shock-absorbing movable block 22, thereby pressing down on the two sets of shock-absorbing springs 21 at the bottom, thus reducing vibration through the shock-absorbing springs 21.

[0024] The adjusting wheel device 20 includes a moving frame 23, anti-slip wheels 24, a steering motor 25, and a drive motor 26. The moving frame 23 has an L-shaped structure. A rotating gear 27 is mounted on the top of the moving frame 23 via a rotating shaft. The steering motor 25 is mounted on the top right side of the moving frame 23. A small gear 28 is provided at the top drive end of the steering motor 25, and the small gear 28 is connected to the rotating gear 27. The anti-slip wheels 24 are mounted inside the moving frame 23, and the drive motor 26 is mounted on the outside of the moving frame 23. The drive end of the drive motor 26 is connected to the drive end of the anti-slip wheels 24. When adjusting the direction of the entire device body 1, the steering motor 25 can be used. The steering motor 25 drives the small gear 28 to rotate, which in turn drives the rotating gear 27 to rotate. The rotating gear 27 can then drive the entire moving frame 23 at the bottom to rotate via a bearing, thereby adjusting the anti-slip wheels 24 inside the moving frame 23. During driving, the drive motor 26 drives the anti-slip wheels 24 to rotate via a drive shaft, thereby achieving the purpose of displacement.

[0025] Working principle: During operation, when adjusting the angle of the cleaning device 6, the operator activates the synchronous belt device 8 inside the follower slide rail 7. The synchronous belt device 8 drives the sliding wheel 9 to move up or down within the follower slide rail 7. The sliding wheel 9 is installed with the roller brush cover 10 through the rotating shaft mounting block 12, so that one end of the sliding wheel 9 moves upward, and the sliding wheel 9 and the roller brush cover 10 can rotate (similar to the principle of a hinge). After adjusting the position of a set of sliding wheels 9, the cleaning device 6 can be tilted to fit against the photovoltaic panel. When cleaning the photovoltaic panel, the operator activates the cleaning motor transmission assembly 11. The driving end of the cleaning motor transmission assembly 11 drives the drive rod 13 to rotate, and then the cleaning brush 14 on the drive rod 13 can clean the dust on the photovoltaic panel by rotating.
