[0031] A brush body 33 for cleaning the cleaning roller 24 is arranged in the box body 31; a through hole 311 is arranged on the side wall of the box body 31; the ventilation mechanism 4 includes a rotating frame 42 rotating in the box body 31, and a plurality of blades 43 rotatably mounted on the rotating frame 42; the rotating axis of the blade 43 is perpendicular to the rotating axis of the rotating frame 42; the rotating axis of the rotating frame 42 is perpendicular to the side wall of the box body 31; when the blade 43 is in the first position, each blade 43 abuts against the side wall of the box body 31 and closes the through hole 311; when the blade 43 is in the second position, each blade 43 has an angle with the box body 31, at this time, the rotating frame 42 rotates, and the blade 43 will generate airflow.

[0032] The blades 43 in the two ventilation mechanisms 4 rotate in opposite directions, and when the rotating frame 42 rotates, one ventilation mechanism 4 draws the outside air into the box body 31, and the other ventilation mechanism 4 discharges the air in the box body 31 to the outside.

[0033] The ventilation mechanism 4 also includes a driving seat 44 that is coaxially arranged with the rotating frame 42 and rotates on the side wall of the box body 31; the rotating frame 42 slides axially in the driving seat 44; the blade 43 is coaxially provided with a blade gear 431; and a rack 442 that meshes with the blade gear 431 is provided on the driving seat 44.

[0034] The driving seat 44 is provided with a plurality of limit frames 441; the rotating frame 42 slides axially with the limit frames 441; a rotating socket 422 with a non-circular cross section is provided in the rotating frame 42; the driving seat 44 is provided with a plug connected with the rotating socket 422, so that the driving seat 44 and the rotating frame 42 rotate synchronously in the circumferential direction and slide relative to each other in the axial direction.

[0035] The ventilation mechanism 4 also includes a positioning ring 41 fixed to the side wall of the box body 31; the inner wall of the positioning ring 41 is provided with a circular slide groove 411 coaxially arranged with the driving seat 44; the inner wall of the positioning ring 41 is provided with a spirally distributed inclined groove 412; one end of the inclined groove 412 is connected to the slide groove 411; the outer wall of the rotating frame 42 is provided with a sliding column 421 sliding with the slide groove 411 and the inclined groove 412.

[0036] When the slide post 421 is located in the inclined slot 412 at one end away from the slide slot 411 , the vane is located in the first position; when the slide post 421 is located in the slide slot 411 , the vane is located in the second position.

[0037] A tension spring 45 is provided between the rotating frame 42 and the box body 31 to drive the rotating frame 42 to move toward the inclined slot 412 .

[0038] The rotating shaft of the driving seat 44 is parallel to the rotating shaft of the cleaning roller 24; a synchronization slot 443 is provided at one end of the driving seat 44 close to the center of the box body 31; synchronization blocks 241 are respectively provided at both ends of the cleaning roller 24; when the housing 21 moves until the cleaning roller 24 and the driving seat 44 are coaxial, the synchronization block 241 is plugged into the synchronization slot 443, and the cleaning roller 24 and the driving seat 44 rotate synchronously.

[0039] The two ends of the synchronization slot 443 are connected to the side wall of the driving seat 44. When the blade outer 3 is in the first position, the synchronization slot 443 is in a horizontal position, and the two ends of the synchronization slot 443 are located in the same horizontal plane. At this time, the synchronization plug 241 can pass through the two ends of the synchronization slot 443 and enter the synchronization slot 443 until the cleaning roller 24 is coaxial with the driving seat 44.

[0040] The end of the box body 31 close to the photovoltaic panel 1 is rotatably connected with a cover plate 32 .

[0041] Two parallel transmission columns 51 are rotatably connected in the box body 31 ; when the cleaning machine 2 is located in the windproof box 3 , a roller 22 abuts against the transmission column 51 ; the transmission column 51 is in transmission connection with the cover plate 32 .

[0042] The roller 22 is located at the upper ends of the two transmission columns 51 and is tangent to the transmission columns 51 , so that the roller 22 and the transmission columns 51 are transmitted, and at this time, when the roller 22 rotates, the housing 21 does not move.

[0043] The cover plate 32 is coaxially provided with a cover plate gear 321 ; a driving gear 54 meshing with the cover plate gear 321 is rotatably connected in the box body 31 ; a transmission column 51 is coaxially provided with an end gear 511 ; the end gear 511 is transmission-connected to the driving gear 54 .

[0044] A transmission gear 52 meshing with the end gear 511 is rotatably connected inside the box body 31; a connecting gear 53 meshing with the transmission gear 52 is rotatably connected inside the box body 31; the connecting gear 53 and the driving gear 54 are connected through a synchronous belt 55, and when the transmission column 51 rotates, the transmission column 51 drives the cover plate 32 to rotate synchronously.

[0045] Four feeding assemblies are arranged in the housing 21; the feeding assembly includes two rollers 22 and a roller motor 23 driving the rollers 22 to rotate; the two rollers 22 are connected by a roller driving belt transmission; the two rollers 22 in the feeding assembly are respectively located at the upper and lower ends of the photovoltaic panel.

[0046] A cleaning roller motor for driving the cleaning roller 24 to rotate is fixedly connected inside the housing 21 .

[0047] When working, each roller motor 23 drives the roller 22 to rotate, driving the housing 21 to move on the photovoltaic panel 1, and at the same time, the cleaning roller 24 rotates to clean the surface of the photovoltaic panel 1, and removes the dust, weeds and other debris on the photovoltaic panel 1. During this process, the cover 32 is opened, waiting for the cleaning machine 2 to enter the box 31.

[0048] After the work is completed, the roller 22 rotates, driving the housing 21 to move into the box body 31 until the cleaning roller 24 is coaxial with the driving seat 44, and the synchronous plug block 241 is plugged into the synchronous slot 443. At the same time, one roller 22 moves to abut against the transmission column 51, and the cleaning roller 24 contacts the brush body 33.

[0049] Then the roller 22 rotates, driving the transmission column 51 to rotate synchronously, and then the cover plate 32 rotates through the end gear 511, the transmission gear 52, the connecting gear 53, the synchronous belt 55, the driving gear 54, and the cover plate gear 321 in sequence, until the cover plate 32 closes the box body 31.

[0050] After the cover 32 closes the box body 31, wind and sand from the outside cannot enter the box body 31, thereby avoiding damage to the cleaning machine 2. The cleaning machine 2 is also protected from sunlight, thereby extending its service life.

[0051] As the use time of the cleaning roller 24 increases, debris will be attached to the surface of the cleaning roller 24, affecting the cleaning efficiency. At this time, the cleaning roller 24 rotates forward, and friction is generated between the cleaning roller 24 and the brush body 33, cleaning the debris on the surface of the cleaning roller 24. At the same time, the cleaning roller 24 drives the drive seat 44 to rotate forward synchronously through the synchronous plug block 241, and the rotating frame 42 rotates forward synchronously. At the beginning, the slide column 421 on the rotating frame 42 moves along the inclined groove 412 toward the slide groove 411, and then the rotating frame 42 slides axially, so that the blade gear 431 engages with the rack 422, forcing the blade 43 to rotate, and then the blade 43 and the side wall of the box body 31 form an angle, and the blade 43 moves to the second position. Finally, the slide column 421 moves into the slide groove 411, and then the drive seat 44 continues to rotate, and the slide column 421 will continue to rotate synchronously in the slide groove 411, and the blade 43 remains in the second position.

[0052] As the drive seat 44 rotates, the blades 43 generate axial airflow. The blades 43 in one ventilation mechanism 4 discharge the air in the box body 31 to the outside, and at the same time, the dust, weeds and other debris cleaned by the friction between the cleaning roller 24 and the brush body 33 will be discharged to the outside along with the airflow. The other ventilation mechanism 4 draws the outside air into the box body 31 for replenishment.

[0053] After a certain period of time, the cleaning roller 24 is cleaned. The cleaning roller 24 rotates in the opposite direction, and then the drive seat 44 and the rotating frame 42 rotate in the opposite direction synchronously. When the rotating frame 42 moves to the intersection of the slide post 421 at the slide groove 4111 and the inclined groove 412, the tension of the tension spring 45 will pull the rotating frame 42, so that the slide post 421 moves into the inclined groove 412. As the cleaning roller 24 continues to rotate in the opposite direction, the slide post 421 eventually moves to the extreme position away from the slide groove 411 in the inclined groove 412, and the blade 43 moves to the first position, and the blade 43 closes the passage 311. After that, the slide post 421 cannot continue to move in the opposite direction, which causes the cleaning roller 24 to continue to rotate in the opposite direction, and the torque of the cleaning roller motor increases sharply instantly. Therefore, when the torque of the cleaning roller motor is detected to increase, the cleaning roller motor is controlled to stop working to ensure that each component will not be damaged. At the same time, because the blade 43 closes the passage 311, the box body 31 is completely isolated from the outside world at this time. At this time, the synchronization slot 443 is located in a horizontal position, which is convenient for the movement of the housing 21.

[0054] When working next time, the roller 22 drives the transmission column 51 to rotate, so that the cover 32 is opened. Then the remaining rollers 22 rotate, driving the housing 21 to move to the outside of the box body 31, and the rollers 22 are separated from the transmission column 51.
