[0028] The following is a combination of specific implementation cases and attached Figure 1-5 The present invention is further described below, but the present invention is not limited to these embodiments.

[0029] Example 1

[0030] A cleaning machine for continuously cleaning photovoltaic panels comprises a frame 1, the inner wall of the frame 1 is rotatably provided with a first movable shaft 2, the outer part of the first movable shaft 2 is sleeved with a cleaning roller 3, and the outer wall of the cleaning roller 3 is spirally provided with bristles 10. Bearings are symmetrically embedded and installed on the inner walls on both sides of the frame 1, and the two ends of the first movable shaft 2 are respectively embedded and installed inside the two bearings. The cleaning roller 3 is fixedly sleeved on the outside of the first movable shaft 2 through a mounting hole opened in the center, so that the cleaning roller 3 rotates with the first movable shaft 2. Bristles 10 are spirally installed on the outer wall of the cleaning roller 3 from one end to the other end in a circle. When the bristles 10 rotate with the cleaning roller 3, the entire surface of the photovoltaic panel can be cleaned, so that the bristles 10 are fully in contact with every position on the surface of the photovoltaic panel.

[0031] The outside of the frame 1 is symmetrically sleeved with positioning frames 15, and the outer wall of the frame 1 is provided with an adjustment mechanism for adjusting the two positioning frames 15. The adjustment mechanism allows the two positioning frames 15 to slide relative to or back to back on the outer surface of the frame 1. According to the size of the entire surface area of ​​multiple photovoltaic panels, the positions of the two positioning frames 15 are adjusted so that the positioning frames 15 are attached to both sides of the photovoltaic panels, so that the frame 1 is attached to the surface of the photovoltaic panels.

[0032] With the above structure, when cleaning the photovoltaic panels spliced ​​in a large area, the frame 1 is placed on the surface of the photovoltaic panel in a close fit, and the bristles 10 on the outer wall of the cleaning roller 3 are in close fit with the surface of the photovoltaic panel 1. Then the two positioning frames 15 are adjusted by the adjustment mechanism to move relatively to the positions where the two sides of the photovoltaic panel fit. Then the frame 1 is moved, and the first movable shaft 2 is rotated at the same time, so that the first movable shaft 2 drives the circumferential bristles 10 to rotate continuously in a circumferential direction through the cleaning roller 3. As the frame 1 moves, the photovoltaic panel 1 is cleaned by the spirally arranged bristles 10, so that multiple spliced ​​photovoltaic panels can be cleaned successively and continuously. By moving one side of a large-area photovoltaic panel to the other side for cleaning, the efficiency of cleaning the photovoltaic panel is improved, and the distance between the two positioning frames 15 is adjusted according to the area and shape of the photovoltaic panel, so that photovoltaic panels of different areas can be used for cleaning, thereby bringing convenience to the operation process of relevant personnel.

[0033] The adjusting mechanism includes a lead screw 4, and the two ends of the lead screw 4 are symmetrically connected to the first mounting plates 5 for rotation, and the two first mounting plates 5 are fixedly mounted on the outer wall of the frame 1 respectively. The two first mounting plates 5 are vertically fixed to the surface of the frame 1 in parallel with each other, and the bearings are symmetrically embedded and installed on the opposite surfaces of the two first mounting plates 5, and the two ends of the lead screw 4 are embedded and installed inside the two bearings respectively. The motor is fixed on the surface of the control box 12 through the outer shell. The output shaft of the motor passes through the side wall of the outer shell and the inner cavity corresponding to a first mounting plate 5 and is fixedly connected to one end of the lead screw 4, and the motor is electrically connected to the external power supply through a wire.

[0034] The two positioning frames 15 are symmetrically threadedly connected to the outside of the lead screw 4, and two threaded through holes are symmetrically opened in the inner cavity of the two positioning frames 15. Two parts of external threads with opposite threads and the same pitch are symmetrically opened from the center position to both sides on the outer surface of the lead screw 4, so that when the lead screw 4 rotates, the two positioning frames 15 move relative to or back to back. The outer wall of the positioning frame 15 is provided with a limiting member for clamping the photovoltaic panel.

[0035] With the above structure, when adjusting the positions of the two positioning frames 15 according to the area of ​​the photovoltaic panel, the corresponding motor is connected to the power supply so that the output shaft of the motor drives one end of the corresponding lead screw 4 to rotate, so that the two positioning frames 15 connected by the external thread of the lead screw 4 move relatively. The two positioning frames 15 are respectively attached to the two sides of the photovoltaic panel to be cleaned. Then the frame 1 is moved, and the photovoltaic panel is cleaned successively by the rotating cleaning roller 3, and the positions of the two positioning frames 15 are adjusted according to the area of ​​the photovoltaic panel, thereby bringing convenience to the operation process of the relevant personnel.

[0036] It is worth noting that the limiting member includes a fixed frame 18, which is fixedly mounted on the side wall of the positioning frame 15 near the bottom, and the inner wall of the fixed frame 18 is rotatably provided with a first pulley 1. At both ends of the vertical fixed mounting shaft body on both sides of the inner wall of the fixed frame 18, the first pulley 19 is movably sleeved on the outside of the shaft body through the mounting hole opened in the center, and the first pulley 19 protrudes out of the fixed frame 18. The fixed frame 18 is vertically fixed to the surface of the positioning frame 15 near the bottom, and when the first pulley 19 on the inner wall of the fixed frame 18 is attached to the upper surface of the photovoltaic panel 1, the bristles 10 on the surface of the cleaning roller 3 are attached to the surface of the photovoltaic panel 1.

[0037] The bottom of the fixed frame 18 is provided with a movable frame 11, the inner wall of the movable frame 11 is rotatably provided with a second pulley 17, and the side wall of the positioning frame 15 is provided with an adjustment component for adjusting the position of the movable frame 11. The movable frame 11 is arranged opposite to the fixed frame 18, and the two ends of the fixed shaft body are respectively perpendicular to both sides of the inner wall of the movable frame 11, and the second pulley 17 is movably sleeved on the outside of the shaft body through the mounting hole opened in the center, and the second pulley 17 protrudes out of the movable frame 11.

[0038] With the above structure, when the first pulley 19 of the fixed frame 18 is moved to the upper surface of the photovoltaic panel, the movable frame 11 drives the second pulley 17 to move to a position where it fits the lower surface of the photovoltaic panel and is locked by adjusting the components. The fixed frame 18 and the movable frame 11 on both sides make the first pulley 19 and the second pulley 17 fit the upper and lower surfaces of the photovoltaic panel respectively, ensuring the stability of the cleaning roller 3 in the process of cleaning the photovoltaic panel surface, avoiding position deviation, and thus ensuring the cleaning effect of the photovoltaic panel.

[0039] In addition, the adjustment component includes a sleeve 14, and a sliding rod 16 is embedded in the inner cavity of the sleeve 14. One end of the sliding rod 16 placed outside the sleeve 14 is connected to the movable frame 11, and a bolt for positioning the sliding rod 16 is provided on the side wall of the sleeve 14. The sleeve 14 is movably sleeved on the outside of the sliding rod 16 through the movable cavity opened on the surface, so that the sleeve 14 fits on the outside of the sliding rod 16 and slides. A threaded hole connected to the movable cavity of the sliding rod 16 is opened on the surface of the sleeve 14, so that the bolt passes through the threaded hole and is clamped on the surface of the sliding rod 16, thereby locking the position of the sliding rod 16. One end of the sliding rod 16 outside the sleeve 14 is fixedly connected to the movable frame 11 through a connecting rod and a connecting member.

[0040] With the above structure, when adjusting the position of the second pulley 17, the slide bar 16 is slid inside the sleeve 14, so that the slide bar 16 drives the movable frame 11 to move. When the second pulley 17 is moved to fit the lower surface of the photovoltaic panel, the bolt is screwed to lock the position of the second pulley 17. The position of the second pulley 17 is adjusted according to the thickness of the photovoltaic panel, so that it can be applied to photovoltaic panels of different thicknesses.

[0041] In addition, the outer wall of the frame 1 is symmetrically fixed with second mounting plates 9, a guide rod 8 is fixedly mounted between the two second mounting plates 9, and two positioning frames 15 are symmetrically slidably connected to the outside of the guide rod 8. The two second mounting plates 9 are vertically fixed to the outer wall of the frame 1 in parallel with each other, and the positions of the second mounting plates 9 correspond to the first mounting plates 5. The two ends of the guide rod 8 are respectively vertically fixed to the opposite surfaces of the two second mounting plates 9, and the two positioning frames 15 are movably sleeved on the outside of the guide rod 8 through the mounting holes opened on the surface.

[0042] By adopting the above structure, in the process of rotating the screw 4 to adjust the positions of the two positioning frames 15, the positioning frames 15 are simultaneously slid on the outside of the guide rod 8. The stability of the moving direction of the positioning frames 15 is ensured by the guide rod 8 parallel to the screw 4, thereby ensuring the stability of the moving direction of the frame 1 on the surface of the photovoltaic panel.

[0043] Furthermore, the inner wall of the frame 1 is rotatably provided with a second movable shaft 6, and the outer part of the second movable shaft 6 is evenly sleeved with moving wheels 7. Bearings are symmetrically embedded and installed on the inner walls of both sides of the frame 1, and the two ends of the second movable shaft 6 are respectively embedded and installed inside the two bearings, and a plurality of moving wheels 7 are sequentially fixedly sleeved on the outer part of the second movable shaft 6 through the mounting holes opened in the center, so that the moving wheels 7 rotate with the second movable shaft 6.

[0044] When the frame 1 is placed on the photovoltaic panel for cleaning, the second movable shaft 6 drives the moving wheel 7 to rotate, so that the moving wheel 7 between the two positioning frames 15 fits on the photovoltaic panel and rotates. Thus, the frame 1 drives the cleaning roller 3 to rotate on the photovoltaic panel, and the surface of the photovoltaic panel is continuously cleaned by the continuously moving cleaning roller 3, making the operation of the photovoltaic panel cleaning process more convenient.

[0045] A control box 12 is fixedly mounted on the side wall of the frame 1, and a linkage mechanism for simultaneously driving the first movable shaft 2 and the second movable shaft 6 is provided in the inner cavity of the control box 12. The control box 12 is fixedly fixed on the surface of the frame 1, and the linkage mechanism inside the control box 12 makes the first movable shaft 2 and the second movable shaft 6 rotate synchronously, so that the moving wheel 7 and the cleaning roller 3 rotate simultaneously, thereby making the process of cleaning the photovoltaic panel more convenient.

[0046] The linkage mechanism includes a first rotating shaft 20 and a second rotating shaft 22 which are rotatably arranged on the inner wall of the control box 12. The first rotating shaft 20 is sleeved with a first gear 23 on the outside, and the second rotating shaft 22 is sleeved with a second gear 21 on the outside, and the second gear 21 meshes with the first gear 23. Bearings are respectively embedded and installed on the inner walls on both sides of the control box 12, and the two ends of the first rotating shaft 20 and the second rotating shaft 22 are respectively embedded in the bearings installed on the corresponding inner walls on both sides, so that the first rotating shaft 20 and the second rotating shaft 22 rotate parallel to each other inside the control box 12. The first gear 23 is fixedly sleeved on the outside of the first rotating shaft 20 through a mounting hole opened in the center, and the second gear 21 is fixedly sleeved on the outside of the second rotating shaft 22 through a mounting hole opened in the center. The positions of the first rotating shaft 20 and the second rotating shaft 22 correspond to each other, so that the teeth of the first gear 23 and the second gear 21 mesh.

[0047] When the two groups of cleaning rollers 3 are driven to rotate by the two first rotating shafts 20, the two first rotating shafts 20 are distributed on both sides of the second rotating shaft 22, so that the second gear 21 located in the middle is meshed with the first gears 23 on both sides at the same time. The motor is fixedly installed through the shell on the outer surface of the control box 12 and at a position corresponding to the second rotating shaft 22. The output shaft of the motor is fixedly connected to one end of the second rotating shaft 22, and the motor is electrically connected to the external power supply through a wire. When cleaning the surface of the photovoltaic panel, the motor is connected to the power supply so that the output shaft of the motor drives the second rotating shaft 22 to rotate, and the second rotating shaft 22 drives the second gear 21 to rotate. The first gear 23 meshing with the second gear 21 drives the first rotating shaft 20 to rotate, so that the second rotating shaft 22 drives the moving wheel 7 to rotate, and at the same time, the first rotating shaft 20 drives the cleaning roller 3 to rotate, so that the operation of the photovoltaic panel cleaning process is more convenient.

[0048] A guide wheel is provided between the frame 1 and the positioning frame 15. Figure 5 As shown, guide wheels are installed on the inner wall of the positioning frame 15 and at a position opposite to the outer wall of the frame 1. The guide wheels ensure the fit between the positioning frame 15 and the outer wall of the frame 1 and can also reduce the friction of the contact surface, thereby ensuring the stability of the frame 1 on the photovoltaic panel.

[0049] The present embodiment is a cleaning machine for continuously cleaning photovoltaic panels, and the working principle is as follows: when the photovoltaic panels are continuously cleaned, the frame 1 is placed on the surface of the photovoltaic panels, and the bristles 10 on the outer wall of the cleaning roller 3 are in contact with the surface of the photovoltaic panels 1, and then the output shaft of the motor drives one end of the corresponding lead screw 4 to rotate. The two positioning frames 15 connected by the external thread of the lead screw 4 move relative to each other, so that the two positioning frames 15 are respectively in contact with the two sides of the photovoltaic panel to be cleaned, and the first pulley 19 on the inner wall of the fixed frame 18 is in contact with the upper surface of the photovoltaic panel 1, and the slide bar 16 is slid inside the sleeve 14, so that the slide bar 16 drives the movable frame 11 to move. When the second pulley 17 is moved to be in contact with the lower surface of the photovoltaic panel, the bolt is tightened to lock the position of the second pulley 17. Then the motor installed on the surface of the control box 12 is connected to the power supply, so that the output shaft of the motor drives the second rotating shaft 22 to rotate, so that the second rotating shaft 22 drives the second gear 21 to rotate, and the first gear 23 meshing with the second gear 21 drives the first rotating shaft 20 to rotate. The second rotating shaft 22 drives the moving wheel 7 to rotate, and the first rotating shaft 20 drives the cleaning roller 3 to rotate. As the frame 1 moves on the photovoltaic panel, the cleaning roller 3 on the frame 1 continuously cleans the surface of the photovoltaic panel.
