[0022] Example

[0023] The problem to be solved is that the existing gantry cleaning robots for photovoltaic cleaning cannot move on photovoltaic panels at different tilt angles, thus making it impossible to clean photovoltaic panels at different tilt angles and affecting the cleaning of photovoltaic panels by workers.

[0024] The solution is as follows: A pulley device for a gantry photovoltaic cleaning robot includes a device body 1. The device body 1 includes a gantry 2, a movable slide rail 3, a pulley device 4, and a photovoltaic cleaning robot 5. The movable slide rail 3 is installed inside the gantry 2, and the pulley device 4 is installed inside the movable slide rail 3. The photovoltaic cleaning robot 5 is installed on the inner mounting end of the pulley device 4 via a rotating shaft. The pulley device 4 includes a robot mounting arm 6, a first sliding device 7, and a second sliding device 8. A set of first sliding devices 7 is provided, and the set of first sliding devices 7 is symmetrically connected by bolts. Installed on the right end of the robot mounting arm 6, a set of second sliding devices 8 is provided, and a set of second sliding devices 8 are symmetrically installed on the right end of the first sliding device 7 by bolts; the first sliding device 7 includes a main sliding frame 9 and a first moving wheel 10. The main sliding frame 9 has an L-shaped structure, and a set of first moving wheels 10 is provided, and a set of first moving wheels 10 are installed on the inner side of the main sliding frame 9 in a transversely equidistant manner. The main sliding frame 9 includes a mounting plate 11 and a fixing plate 12. The mounting plate 11 and the fixing plate 12 are smoothly transitioned and integrally formed. The fixing plate 12... Located at the left end of the mounting plate 11, both the mounting plate 11 and the fixing plate 12 are rectangular in shape, and both the mounting plate 11 and the fixing plate 12 have several sets of mounting holes 13 on their surfaces. The second sliding device 8 includes an auxiliary sliding frame 14 and second moving wheels 15. The auxiliary sliding frame 14 is L-shaped, and there are three second moving wheels 15. The three second moving wheels 15 are installed in a row at equal intervals at the right end of the auxiliary sliding frame 14. In use, the three sets of second moving wheels 15 can respectively fit against the left and right sides of the moving track 3, while the first moving wheel 10 can fit against the inner side of the moving track 3. In this way, the pulley device 4 can slide up and down within the sliding track 3. When driving the pulley device 4, it is only necessary to assemble a drive device on the moving track 3 to drive it. The drive device can be equipped with a synchronous belt drive. When cleaning photovoltaic panels with different tilt angles, the staff can adjust the height of a set of pulley devices 4, such as the left pulley device 4 being higher and the right pulley device 4 being slightly lower. Thus, the two ends of the photovoltaic cleaning robot 5 can be adjusted by rotating the shaft to tilt the photovoltaic cleaning robot 5 so that it can fit onto the tilted photovoltaic panel.

[0025] The auxiliary sliding frame 14 includes a reinforcing plate 16 and an assembly plate 17. The reinforcing plate 16 and the assembly plate 17 are smoothly transitioned and integrally formed. The reinforcing plate 16 is located at the right end of the assembly plate 17. The reinforcing plate 16 has a trapezoidal shape, and the assembly plate 17 has a rectangular shape. Both the reinforcing plate 16 and the assembly plate 17 have several sets of mounting holes 13. The auxiliary sliding frame 14 is for mounting the second moving wheel 15. The smooth transition and integral forming of the reinforcing plate 16 and the assembly plate 17 improve the overall strength and stability of the structure.

[0026] The robot mounting arm 6 includes a mounting beam 18 and rotating mounting blocks 19. A set of rotating mounting blocks 19 are provided, and the set of rotating mounting blocks 19 and the mounting beam 18 are smoothly transitioned and integrally formed. The mounting beam 18 has a rectangular structure, and the rotating mounting blocks 19 have an n-shaped structure. A pivot mounting hole 20 is provided on the surface of the rotating mounting block 19, and several sets of mounting holes 13 are provided on the surface of the mounting beam 18. When installing the photovoltaic cleaning robot 5, the outer end of the photovoltaic cleaning robot 5 is inserted between a set of rotating mounting blocks 19. The operator inserts a pivot into the pivot mounting hole 20 of the rotating mounting block 19, and then inserts the pivot into the fixed end of the photovoltaic cleaning robot 5 for connection. A set of first sliding devices 7 and second sliding devices 8 can be adjusted to accommodate different moving slide rails 3.

[0027] Working principle: During operation, the three sets of second moving wheels 15 can respectively attach to the left and right sides of the moving track 3, while the first moving wheel 10 can attach to the inner side of the moving slide rail 3. In this way, the pulley device 4 can easily slide up and down within the sliding track 3. To drive the pulley device 4, simply assemble a drive device on the moving track 3. The drive device can be equipped with a synchronous belt drive. When cleaning photovoltaic panels with different tilt angles, the operator can adjust the height of one set of pulley devices 4. For example, the left pulley device 4 is higher and the right pulley device 4 is slightly lower. Thus, the two ends of the photovoltaic cleaning robot 5 can be adjusted by rotating the shaft to tilt the photovoltaic cleaning robot 5, so that it can attach to the tilted photovoltaic panel.

All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this invention is that the gantry cleaning robot in existing photovoltaic cleaning robots cannot walk on photovoltaic panels at different tilt angles, thus preventing the cleaning of photovoltaic panels at different tilt angles and affecting the cleaning work of workers. This invention, through the combination of the above components, enables the gantry cleaning robot to walk smoothly on photovoltaic panels at different tilt angles, while ensuring that the cleaning device is in close contact with the panel surface.
