[0027] The cleaning brush 17 can be a soft brush made of high-quality fiber and wool. The soft brush with high-quality fiber and wool not only provides a soft touch, but also is not easy to damage the surface of objects. It can effectively remove dust and dirt on the surface of the photovoltaic panel 1 while avoiding scratching the surface of the photovoltaic panel 1.

[0028] A splicing block 12 is fixedly provided on the end face of one end of the cleaning strip 6, and a first splicing hole 11 matching the splicing block 12 is opened on the end face of the cleaning strip 6 away from the splicing block 12. The transmission assembly includes a plurality of linkage gears 21 rotatably arranged on the bottom wall of the cleaning groove 13 and meshing with each other, and a transmission gear 22 penetrating the splicing block 12 and meshing with one of the linkage gears 21. The plurality of linkage gears 21 are respectively connected to a plurality of cleaning brushes 17 in a one-to-one correspondence through a buffer assembly.

[0029] The buffer assembly includes a mounting bar 14 which is arranged on a plurality of linkage gears 21 and whose sides are fixedly connected to the groove wall of the cleaning groove 13, a plurality of buffer telescopic rods 15 which are arranged one by one between adjacent linkage gears 21 and cleaning brushes 17 and whose one end movably passes through the mounting bar 14 and is connected to the end surface of the linkage gear 21 and whose other end is connected to the cleaning brush 17, and a buffer spring 16 which is movably sleeved on the body of the buffer telescopic rod 15 and whose two ends are respectively connected to the mounting bar 14 and the cleaning brush 17 through a rotating ring.

[0030] like Figure 1-4As shown, when it is necessary to clean the surface of the photovoltaic panel 1, the driving assembly drives the transmission gear 22 to rotate, that is, drives a plurality of mutually meshing linkage gears 21 to rotate, and the plurality of linkage gears 21 are respectively rotated through the buffer telescopic rod 15 and the plurality of cleaning brushes 17, and the rotating cleaning brush 17 cleans the dust on the surface of the photovoltaic panel 1, thereby improving the cleaning efficiency and cleaning effect of the surface of the photovoltaic panel 1, and the buffer telescopic rod 15 can only be telescoped in the length direction, so that when the linkage gear 21 rotates, it drives the plurality of cleaning brushes 17 to clean the dust on the surface of the photovoltaic panel 1, and a buffer spring 16 in a compressed state is sleeved on the rod body of the buffer telescopic rod 15, and when the cleaning strip 6 is set on the surface of the photovoltaic panel 1, the cleaning brush 17 fits with the surface of the photovoltaic panel 1, and under the action of the buffer spring 16, it is easy to ensure that the cleaning brush 17 fits closely with the photovoltaic panel 1, and under the action of the rotating cleaning brush 17, the dust on the surface of the photovoltaic panel 1 is fully cleaned, thereby improving the dust cleaning effect on the surface of the photovoltaic panel 1.

[0032] like Figure 1-4 As shown, in the process of installing the cleaning strip 6 on the surface of the photovoltaic panel 1, the splicing block 12 set at the end of the cleaning strip 6 is inserted into the second splicing hole opened on the side of the control block 5, and the driving gear located in the second splicing hole is meshed with the transmission gear 22 set in the splicing block. The driving motor on the control block 5 drives the driving gear to rotate, and the transmission gear can drive multiple mutually meshing linkage gears 21 to rotate, so that the multiple cleaning brushes 17 can be controlled to rotate, so as to fully clean the surface of the photovoltaic panel 1.

[0033] When the length of the photovoltaic panel 1 is too long, the two cleaning strips 6 can be connected end to end, and the splicing block 12 set at one end of one of the cleaning strips 6 can be inserted into the first splicing hole 11 opened at the end of the other cleaning strip 6. At this time, the transmission gear 22 inserted in the splicing block 12 is engaged with one of the multiple linkage gears 21 in the other cleaning strip 6, so that the multiple cleaning brushes 17 on two or more cleaning strips 6 can rotate synchronously, which is convenient for cleaning dust on the surface of a larger area of ​​the photovoltaic panel 1, thereby improving the cleaning efficiency and effect of the cleaning strip 6 on the surface of the photovoltaic panel 1.

[0034] The cleaning mechanism also includes a fixing component for fixing the position between the two cleaning strips 6, the fixing component including two clamping blocks 19 movably inserted into the sliding grooves provided in the symmetrical hole walls of the first splicing hole 11, a positioning member for setting the clamping block 19 on the bottom wall of the sliding groove, two control rods 27 arranged in the vertical direction and fixed at the bottom end on the top end surface of the clamping block 19, a pressing block 20 arranged on the side of the cleaning strip 6 away from the photovoltaic panel 1, a connecting rod 25 fixedly arranged on the bottom end surface of the pressing block 20 and movably inserted into the cleaning strip 6 at the bottom, and two linkage rods 26 whose top ends are rotatably connected to the bottom ends of the connecting rods 25 and whose bottom ends are rotatably connected to the top ends of different control rods 27, and clamping grooves 18 matching the clamping blocks 19 are provided on the symmetrical sides of the splicing block 12.

[0035] like Figure 1-5 As shown, when two or more cleaning strips 6 are connected end to end, the splicing block 12 set at the end of one cleaning strip 6 is inserted into the first splicing hole 11 opened at the end of the other cleaning strip 6. At this time, the transmission gear 22 set in the splicing block 12 is meshed with the linkage gear 21 inserted into the first splicing hole 11, so as to ensure that the multiple linkage gears 21 in the two or more cleaning strips 6 rotate synchronously, so as to make the multiple cleaning brushes 17 set in the cleaning groove 13 rotate, thereby improving the cleaning effect of the dust on the surface of the photovoltaic panel 1, and when the splicing block 12 is inserted into the first splicing hole 11, the clamping block 19 movably inserted into the sliding groove will be inserted into the clamping groove 18, so as to facilitate the installation and fixation between the two or more cleaning strips 6, and to facilitate the cleaning of the dust on the surface of photovoltaic panels 1 of different sizes.

[0036] The positioning member includes a positioning telescopic rod 23 which is inserted into the sliding groove and has two ends respectively connected to the bottom wall of the sliding groove and the clamping block 19 , and a positioning spring 24 which is movably inserted into the body of the positioning telescopic rod 23 .

[0037] like Figure 5 As shown, the positioning spring 24 is in a compressed state. When it is necessary to disassemble two or more cleaning strips 6 installed together, the pressing block 20 is controlled to move in the direction of the cleaning strip 6. At this time, the two control rods 27 are driven away from each other by the two linkage rods 26, so as to drive the two clamping blocks 19 passing through the sliding groove to move into the sliding groove, thereby facilitating the disassembly of the two cleaning strips 6 installed together.

[0038] The bottom end of the connecting rod 25 is arranged in the cleaning bar 6 through a resetting telescopic rod 28 , and a resetting spring 29 is movably sleeved on the rod body of the resetting telescopic rod 28 .

[0039] Two connecting grooves 7 are provided at the top and bottom end faces of the photovoltaic panel 1 near the higher side, and mounting grooves 8 are provided at the end faces of the photovoltaic panel 1 on both sides of the two connecting grooves 7. The mounting mechanism includes a mounting bar 3 arranged on the side of the photovoltaic panel 1 on the higher side where the photovoltaic panel 1 is inclined, a moving component arranged on the mounting bar 3 and capable of controlling the control block 5 to move along the length direction of the mounting bar 3, a connecting block 10 arranged on the side of the mounting bar 3 and movably inserted into the connecting groove 7, and a fixing component for fixing the position between the mounting bar 3 and the photovoltaic panel 1.

[0040] A clamping hole 9 is provided on the bottom wall of the mounting groove 8, and the fixing assembly includes a mounting block movably inserted into the mounting groove 8, a clamping block 35 fixedly provided on the end surface of the mounting block and movably inserted into the clamping hole 9, a limiting strip 34 fixedly provided on the mounting block and capable of being attached to the mounting strip 3, and a fixing bolt movably passing through one end of the limiting strip 34.

[0041] The moving assembly includes a moving block 32 fixedly arranged on the bottom end surface of the control block 5 and movably arranged in a moving groove 4 opened along the length direction on the top side of the mounting strip 3, a fixed rack 31 fixedly arranged on the bottom wall of the moving groove 4, a control gear driven by a motor and meshing with the fixed rack 31 and a limit block fixedly arranged on the side of the moving block 32 and movably arranged in a limit groove 30 opened in the groove wall of the moving groove 4.

[0042] One end of the mounting bar 3 is fixedly mounted on a fixing block, and a fixing hole 33 matching the fixing block is formed on the fixing block and on one end of the mounting bar 3 away from the fixing block.

[0043] When installing the mounting strip 3 on the higher side of the photovoltaic panel 1, first control the connecting block 10 arranged on the side of the mounting strip 3 to penetrate into the connecting groove 7 opened in the photovoltaic panel 1, so that the position between the mounting strip 3 and the photovoltaic panel 1 can be relatively fixed, and then control the mounting block to be installed in the mounting groove 8, and at this time, the clamping block 35 arranged on the end face of the mounting block is penetrated in the clamping hole 9, and the position of the two limiting strips 34 can be fixed by passing the bolts through one end of the two limiting strips 34, so that the mounting strip 3 can be stably installed and fixed on the higher side position of the photovoltaic panel 1, and the moving block 32 arranged on the bottom end face of the control block 5 is controlled to penetrate into the moving groove 4, and at this time, the control gear penetrated on the moving block 32 is meshed, and the control gear Driven by a motor, it is convenient to adjust the control block 5 to move on the mounting strip 3, that is, to drive the cleaning strip 6 to move on the surface of the photovoltaic panel 1, and cooperate with the rotation of multiple cleaning brushes 17 arranged in the cleaning groove 13 to clean the surface of the photovoltaic panel 1. When cleaning multiple adjacent photovoltaic panels 1, it is only necessary to control the multiple mounting strips 3 to be installed and fixed on the top side surfaces of the multiple photovoltaic panels 1 and control the fixing blocks arranged at one end of each of the adjacent mounting strips 3 to pass through the opened fixing holes 33, so as to fix the positions between the multiple mounting strips 3 and ensure that the control block 5 moves on the multiple mounting strips 3, driving the cleaning strip 6 to clean the dust on the surfaces of the multiple photovoltaic panels 1, thereby improving the cleaning efficiency and effect of the photovoltaic panels 1.

[0044] In the prior art, when manually removing dust from the surfaces of a large number of photovoltaic panels 1, water is sprayed on the surfaces of the photovoltaic panels 1 to clean the dust on the surfaces of the photovoltaic panels 1. On the one hand, a large amount of water resources need to be wasted. On the other hand, manually cleaning the dust on the surfaces of the photovoltaic panels 1 requires a large amount of manpower and consumes a lot of time to clean the dust on the surfaces of the photovoltaic panels 1. The efficiency of cleaning the dust on the surfaces of the photovoltaic panels 1 is low. In the present application, mounting strips 3 are installed on the higher side surfaces of a plurality of parallel photovoltaic panels 1. The mounting strips 3 are provided with connecting grooves 7 that can be clamped in the surfaces of the photovoltaic panels 1. The positions between the mounting strips 3 and the photovoltaic panels 1 can be quickly pre-fixed. Before fixing the mounting strips 3 on the plurality of photovoltaic panels 1, the ends of two adjacent mounting strips 3 can be plugged together and fixed. The plurality of mounting strips 3 can be quickly and stably installed and fixed on the higher side surfaces of the photovoltaic panels 1, and then one end of one or more cleaning strips 6 can be fixed to the position between the control block 5.

[0045] The motor arranged on the control block 5 drives the control gear arranged in the moving block 32 to rotate, thereby driving the moving block 32 to move in the moving groove 4, that is, driving the cleaning strip 6 to move on the surfaces of multiple photovoltaic panels 1, thereby completing dust removal on the surfaces of multiple photovoltaic panels 1.

[0046] After long-term use, the cleaning brush 17 set on the cleaning strip 6 will be contaminated with dust, which reduces the subsequent cleaning effect of the dust on the surface of the photovoltaic panel 1. The cleaning strip 6 can be removed from the control block 5, and then the splicing block 12 set on the new cleaning strip 6 can be installed on the control block 5. The cleaning strip 6 can be replaced, ensuring the subsequent cleaning effect of the dust on the surface of the photovoltaic panel 1.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
