[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Figure 1-7 As shown, this utility model provides a cleaning device for photovoltaic panels, including two base plates 1, with a frame plate 2 detachably installed between the two base plates 1. Two fixing bolts 11 are threadedly rotatably installed at one end of each of the two base plates 1. One end of the fixing bolts 11 is threadedly rotatably connected to one end of the frame plate 2. By setting the fixing bolts 11, it is easy for operators to fix the frame plate 2 between the two base plates 1. The bottom ends of the two base plates 1 are fixed to the ground by expansion screws. The frame plate 2 is located above the photovoltaic panel. A cleaning mechanism 3 is provided on the frame plate 2. The cleaning mechanism 3 is provided with a disassembly and assembly component 5. By setting the cleaning mechanism 3 and the disassembly and assembly component 5, the cleaning mechanism 3 can automatically clean the dust and impurities on the photovoltaic panel, avoiding the accumulation of dust and impurities on the photovoltaic panel and affecting the power generation efficiency. At the same time, it reduces the maintenance work intensity of the photovoltaic panel maintenance personnel. The disassembly and assembly component 5 can facilitate the disassembly and assembly of the consumable parts on the cleaning mechanism 3, thereby facilitating the replacement of consumable parts by maintenance personnel.

[0030] The cleaning mechanism 3 includes an L-shaped frame 31, with a rotating shaft 32 rotatably mounted on one end of the L-shaped frame 31. A rotating roller 33 is provided on one end of the rotating shaft 32, and a cleaning sponge sleeve 331 is fitted onto the rotating roller 33. A movable frame 34 is slidably mounted on the upper surface of the frame plate 2. A slide groove 35 is provided on the frame plate 2, and a slider 36 is slidably mounted on one end of the slide groove 35. One end of the movable frame 34 is fixedly connected to the upper surface of the slider 36. By setting the slider 36, the slider 36 can slide horizontally along the inner wall of the slide groove 35. The lower surface of the slider 36 is fixed. A connecting plate 37 is installed, with one end of the connecting plate 37 fixedly connected to the other end of the L-shaped frame 31. When the slider 36 can slide horizontally along the inner wall of the slide groove 35, the slider 36 can cause the L-shaped frame 31 and the rotating shaft 32 to move the rotating roller 33 and the cleaning sponge sleeve 331 horizontally through the connecting plate 37. When the cleaning sponge sleeve 331 contacts the upper surface of the photovoltaic panel, the cleaning sponge sleeve 331 can wipe away the dust and impurities on the upper surface of the photovoltaic panel, thereby realizing the automatic cleaning of dust and impurities on the upper surface of the photovoltaic panel.

[0031] A motor 38 is fixedly mounted on the other end of the movable frame 34. A U-shaped fixed frame 39 is fixedly mounted on the fixed end of the motor 38. One end of the U-shaped fixed frame 39 is fixedly connected to the other end of the movable frame 34. A rotating rod 4 is fixedly mounted on the drive output end of the motor 38. The rotating rod 4 is rotatably connected to the movable frame 34. A drive gear 41 is fixedly mounted on one end of the rotating rod 4. A toothed plate 42 is fixedly mounted on the upper surface of the frame plate 2. The drive gear 41 and the toothed plate 42 are meshed together. When the motor 38 is turned on, the drive shaft of the motor 38 can rotate the drive gear 41 through the rotating rod 4. Under the action of the toothed plate 42, the drive gear 41 moves horizontally during rotation, thereby causing the movable frame 34 to move horizontally synchronously. The movable frame 34 causes the slider 36 to slide horizontally within the slide groove 35.

[0032] A first transmission rod 43 is rotatably mounted on the movable frame 34. A bevel gear 44 is fixedly mounted on the middle part of the rotating rod 4 and one end of the first transmission rod 43. The two bevel gears 44 are meshed and connected.

[0033] A second transmission rod 45 is rotatably mounted on one end of the connecting plate 37. A first synchronous pulley 46 is fixedly mounted on the other end of the first transmission rod 43 and one end of the second transmission rod 45. A first synchronous belt 47 is driven between the two first synchronous pulleys 46. A second synchronous pulley 48 is fixedly mounted on the other end of the second transmission rod 45 and the other end of the rotating shaft 32. A second synchronous belt 49 is driven between the two second synchronous pulleys 48. When the rotating rod 4 rotates, the rotating rod 4 can cause the first transmission rod 43 to rotate through the bevel gear 44. The first transmission rod 43 can cause the second transmission rod 45 to rotate through the first synchronous pulley 46 and the first synchronous belt 47. The second transmission rod 45 can cause the rotating shaft 32 to rotate through the second synchronous pulley 48 and the second synchronous belt 49. The rotating shaft 32 can cause the rotating roller 33 to rotate the cleaning sponge sleeve 331.

[0034] The assembly / disassembly component 5 includes a threaded rod 51, one end of which is fixedly connected to one end of a rotating shaft 32. The threaded rod 51 passes through a rotating roller 33. A fixed plate 52 is fixedly installed at one end of the threaded rod 51, and a pressure plate 53 is rotatably installed at the other end of the threaded rod 51. The rotating roller 33 is located between the fixed plate 52 and the pressure plate 53. Rubber pads 54 are fixedly installed on opposite sides of the fixed plate 52 and the pressure plate 53. One side of the rubber pad 54 is in movable contact with one end of the rotating roller 33. The assembly / disassembly component 5 consists of the threaded rod 51, the fixed plate 52, the pressure plate 53, and the pressure plate 53. When the rotating shaft 32 rotates, the rotating shaft 32 can cause the rotating roller 33 and the cleaning sponge sleeve 331 to rotate through the threaded rod 51, the fixed plate 52, the pressing plate 53 and the rubber pad 54. When the rotating roller 33 is sleeved outside the threaded rod 51, one end of the rotating roller 33 abuts against one side of the fixed plate 52. When the pressing plate 53 rotates on the threaded rod 51, it can press the rotating roller 33, thereby fixing the rotating roller 33 and the cleaning sponge sleeve 331. The rotating roller 33 and the cleaning sponge sleeve 331 can be disassembled by reversing the operation.

[0035] Working principle: When it is necessary to clean the dust and impurities on the surface of the photovoltaic panel, the operator first fixes the two base plates 1 on both sides of the photovoltaic panel, and then fixes the frame plate 2 between the two base plates 1 with fixing bolts 11. At this time, the frame plate 2 is located above the photovoltaic panel.

[0036] Subsequently, the operator starts the motor 38. The drive shaft of the motor 38 rotates the drive gear 41 via the rotating rod 4. Under the action of the gear plate 42, the drive gear 41 moves horizontally during rotation. At this time, the moving frame 34 moves horizontally synchronously, causing the slider 36 to slide horizontally within the slide groove 35. The slider 36, through the connecting plate 37, causes the L-shaped frame 31, the rotating shaft 32, and the threaded rod 51 to move the rotating roller 33 and the cleaning sponge sleeve 331 horizontally. Simultaneously, the rotating rod 4 rotates the first transmission rod 43 via two bevel gears 44. The first transmission rod 43 rotates the second transmission rod 45 via two first synchronous pulleys 46 and a first synchronous belt 47. The second transmission rod 45 causes the rotating shaft 32 to rotate via two second synchronous pulleys 48 and a second synchronous belt 49. The rotating shaft 32 causes the rotating roller 33 to rotate via the threaded rod 51. When the cleaning sponge sleeve 331 contacts the upper surface of the photovoltaic panel, the cleaning sponge sleeve 331 wipes away the dust and impurities on the upper surface of the photovoltaic panel while moving horizontally and rotating on its own axis. This facilitates the automatic cleaning of dust and impurities on the upper surface of the photovoltaic panel, thereby effectively improving the convenience of cleaning the photovoltaic panel, preventing dust and impurities from accumulating on the photovoltaic panel and affecting the power generation efficiency, and reducing the maintenance workload of photovoltaic panel maintenance personnel.

[0037] When it is necessary to replace the rotating roller 33 and the cleaning sponge sleeve 331, the operator manually rotates the clamping plate 53 counterclockwise, so that the clamping plate 53 rotates on the threaded rod 51 until the clamping plate 53 disengages from the threaded rod 51. Then, the rotating roller 33 and the cleaning sponge sleeve 331 (the base material of the cleaning sponge sleeve 331 is an elastic material, which is placed on the rotating roller 33) are removed from the threaded rod 51. The operation is reversed to fix the replaced rotating roller 33 and the cleaning sponge sleeve 331 on the threaded rod 51, thus facilitating the replacement of the rotating roller 33 and the cleaning sponge sleeve 331.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
