[0025] Example 1

[0026] As Figures 1 to 6 shown, the dust removal device for photovoltaic modules in this embodiment includes a dust removal guide rail 1, which is composed of several sections assembled together. The adjacent two sections of the dust removal guide rail 1 are assembled and connected through an assembling mechanism 4. A moving pedestal 2 is arranged on the dust removal guide rail 1 through a moving mechanism. The dust removal guide rail 1 is arranged in a U-shaped groove structure. Fixing holes 7 are provided at the bottom of the dust removal guide rail 1. The dust removal guide rail 1 is fixedly installed on the installation platforms on the opposite sides of the photovoltaic panel 5 through bolts in the fixing holes 7. There are two dust removal guide rails 1. Dust removal plates 3 are arranged on the sides of the moving pedestals 2 on the two dust removal guide rails 1 that are close to each other. Dust removal brushes 31 are provided at the bottom of the dust removal plates 3. Support mechanisms are arranged at the opposite ends of the dust removal guide rail 1 to realize large-area integrated dust removal operation of the photovoltaic panel 5 in the area between the two dust removal guide rails 1. The dust removal is convenient and safe. Moreover, the dust removal guide rail 1 is composed of several sections through the assembling mechanism 4, so that the length of the dust removal guide rail 1 is adapted to the photovoltaic panel 5, and the assembled dust removal guide rail 1 can continuously remove dust, and the assembly is convenient.

[0027] Specifically, the dust removal guide rail 1 includes a first guide rail 11, a second guide rail 12, and a third guide rail 13. One ends of the first guide rail 11 and the second guide rail 12 that are close to each other form the dust removal guide rail 1 through the assembling mechanism 4. The first guide rail 11 and the second guide rail 12 are spliced with the third guide rail 13 through the assembling mechanism 4 to form the dust removal guide rail 1. According to the size of the installation of the photovoltaic panel 5, a dust removal guide rail 1 with a suitable length is selected, and the assembled dust removal guide rail 1 can continuously remove dust.

[0028] Furthermore, the assembling mechanism 4 includes a positioning block 41, a positioning groove 42, and a fixing bolt 43. Positioning blocks 41 are provided at one ends of the second guide rail 12 and the third guide rail 13. Positioning grooves 42 are provided at one ends of the first guide rail 11 and the third guide rail 13. Screw holes are provided on the first guide rail 11 and the third guide rail 13 on the opposite sides of the positioning groove 42 and on the positioning block 41. The positioning block 41 is fixed to the positioning groove 42 through the fixing bolt 43 in the screw hole. During assembly, the positioning block 41 is inserted into the positioning groove 42, and the fixing bolt 43 is installed in the screw hole to fix the positioning block 41 and the positioning groove 42, and the toothed plates 24 on the guide rail at the assembly place are butted seamlessly.

[0029] Further, the moving mechanism includes a moving frame 21, a servo motor 22, a gear 23 and a toothed plate 24. The bottom of the moving pedestal 2 is provided with the moving frame 21, the top of the moving frame 21 is provided with the servo motor 22, the output end of the servo motor 22 is connected to the gear 23 through a coupling. The upper end of one side of the dust removal guide rail 1 is provided with the toothed plate 24, and the gear 23 is meshed with the toothed plate 24. The servo motor 22 on the moving frame 21 drives the gear 23 to rotate. Since the gear 23 is meshed with the toothed plate 24 on the dust removal guide rail 1, the moving frame 21 is driven to continuously move inside the dust removal guide rail 1, and the moving pedestal 2 is limited to slide on the dust removal guide rail 1.

[0030] Further, the height of the bottom of the moving frame 21 is higher than the bolts in the fixing holes 7 in the dust removal guide rail 1, that is, the bolts for installation in the dust removal guide rail 1 do not affect the reciprocating movement of the moving frame 21. Limiting seats are provided on both opposite sides of the top of the dust removal guide rail 1, and sliding blocks are provided on both opposite sides of the bottom of the moving frame 21. The sliding blocks are slidably arranged on the limiting seats, and the moving frame 21 is limited and guided to slide, with better stability.

[0031] Furthermore, the dust removal brush 31 is made of a soft brush, and the bottom of the dust removal brush 31 is in contact with the surface of the photovoltaic panel 5. During the process of the dust removal brush 31 moving with the dust removal plate 3, the dust on the surface of the photovoltaic panel 5 is swept away, and the surface of the photovoltaic panel 5 is prevented from being worn by the dust removal brush 31.

[0032] The usage method of this embodiment is as follows: First, select a dust removal guide rail 1 and a dust removal plate 3 with a length adapted to the size of the installation of the photovoltaic panel 5. The dust removal guide rail 1 is provided in several sections, that is, the dust removal guide rail 1 can be an integral section, or can be composed of multiple sections such as a first guide rail 11, a second guide rail 12, and a third guide rail 13 spliced by a splicing mechanism 4. When splicing the dust removal guide rail 1, when the length of the dust removal guide rail 1 formed by splicing the first guide rail 11 and the second guide rail 12 can meet the dust removal stroke length of the photovoltaic panel 5, splice the first guide rail 11 and the second guide rail 12. When the dust removal stroke length of the photovoltaic panel 5 is greater than the length of the dust removal guide rail 1 formed by splicing the first guide rail 11 and the second guide rail 12, splice an appropriate number of third guide rails 13 between the first guide rail 11 and the second guide rail 12. When splicing, the positioning block 41 is inserted into the positioning groove 42, and the fixing bolt 43 is installed in the screw hole to fix the positioning block 41 and the positioning groove 42. The toothed plates 24 on the spliced guide rails are butt-jointed without gaps, that is, the toothed plates 24 on the dust removal guide rail 1 composed of several sections can be continuous. The dust removal guide rail 1 is fixedly installed on the installation platforms on the opposite sides of the photovoltaic panel 5 through bolts in the fixing holes 7, such as on the roof surface. The servo motor 22 on the moving frame 21 drives the gear 23 to rotate. Since the gear 23 is meshed with the toothed plate 24 on the dust removal guide rail 1, the moving frame 21 is driven to continuously move inside the dust removal guide rail 1. The moving pedestal 2 is limited and slides on the dust removal guide rail 1, driving the dust removal plate 3 to move above the photovoltaic panel 5, and using the dust removal brush 31 at the bottom of the dust removal plate 3 to clean and remove the dust on the surface of the photovoltaic panel 5, scraping the dust on the surface of the photovoltaic panel 5 away, realizing the large-area integrated dust removal operation of the photovoltaic panel 5 in the area between the two dust removal guide rails 1. The dust removal is convenient and safe, and the dust removal guide rail 1 is composed of several sections through the splicing mechanism 4, making the length of the dust removal guide rail 1 adapted to the photovoltaic panel 5, and the assembled dust removal guide rail 1 can continuously remove dust, and the assembly is convenient.

[0034] The structure of the dust removal device for the photovoltaic module in this embodiment is basically the same as that of the dust removal device for the photovoltaic module in Embodiment 1, and the difference lies in that: the support mechanism includes a fixing member 6 and a bolt (see Figure 1 and Figure 2 ). The fixing member 6 is arranged in an L-shaped structure. One side of the fixing member 6 is fixedly installed with the dust removal guide rail 1 through a bolt, and the other side of the fixing member 6 is fixedly installed with the photovoltaic panel 5 through a bolt. The photovoltaic panel 5 is inclined and installed on the roof surface, and the dust removal guide rail 1 is installed on the roof surfaces on the opposite sides of the photovoltaic panel 5. The fixing member 6 is fixed to the end plates of the dust removal guide rail 1 and the photovoltaic panel 5 through bolts, playing a role of bearing and supporting the inclined photovoltaic panel 5 by the dust removal guide rail 1, that is, the dust removal guide rail 1 and the L-shaped fixing member 6 clamp and support the inclined photovoltaic panel 5, enabling the dust removal device to increase the installation stability of the photovoltaic panel 5.
