[0009] The guide block is a circular cylindrical structure, the guide block is fixedly connected to the inner side of the long plate, and a guide groove is also provided on the inner side of the long plate. The guide block is used to change the direction of the airflow.

[0015] Preferably, one end of the slide bar is fixedly connected to a stopper A, an outer wall of the stopper A is fixedly connected to an elastic rope B, and one end of the elastic rope B is fixedly connected to the outer wall of the slide block.

[0016] Preferably, the outer wall of the sliding block is fixedly connected with a telescopic plate, one end of the telescopic plate is fixedly connected with a stopper B, and the outer wall of the stopper B is fixedly connected to the bottom of the long board.

[0017] The present invention provides a photovoltaic power generation device on the roof of a passenger car, which has the following beneficial effects:

[0018] 1. The present invention provides a wind cleaning mechanism. Even if the vehicle speed decreases and the wind force decreases, the long board will not be pulled back by the elastic force of the elastic rope A. Only when the passenger car stops driving completely and there is no wind, the long board loses the resistance of the wind, so that the pulling force of the elastic rope A is greater than the magnetic attraction between the magnetic block A and the magnetic block B, thereby completing the automatic pulling and resetting of the long board, and cleaning the surface of the photovoltaic panel again through the bristles, maintaining the photovoltaic power generation stability of the photovoltaic panel under long-term working conditions, and will not be blocked by stains. In addition, through the magnetic attraction between the magnetic block A and the magnetic block B, it is also ensured that the long board will not swing back and forth under different vehicle speeds, and the stability of the passenger car during driving is maintained.

[0019] 2. The present invention sets a wind cleaning mechanism. After the long board is opened and closed, when the wind blows to the long board, it will circulate through the guide grooves provided on the inner wall of the long board, and enter the guide block, and change the ventilation direction through the inner wall of the guide block to complete the diversion and steering of the airflow direction, so that after the long board is opened and closed, the airflow will be changed in direction by the guide block after it is ejected through the guide block to the spraying direction toward the surface of the photovoltaic panel. Therefore, while the photovoltaic panel is blown by the air directly in front, it is also impacted by the airflow laterally through the guide blocks on both sides, so that the air on the surface of the photovoltaic panel generates turbulence, and then the dust adhered to the surface of the photovoltaic panel is better taken away through the irregular airflow fluctuations, so as to complete the more efficient cleaning of the surface of the photovoltaic panel.

[0020] 3. The present invention sets a wind cleaning mechanism, and the airflow through the guide groove and the surface of the long board continues to flow into the ventilation groove in the middle of the fixed block, so that the rear photovoltaic panel is quickly sprayed with concentrated high-pressure airflow through the ventilation groove, so that the surface of the photovoltaic panel located at the rear is also fully cleaned by the airflow, and the high-pressure airflow concentrated through the ventilation groove can remove stubbornly adhered stains, avoiding the problem of the rear photovoltaic panel being slightly blocked by the front.

[0021] 4. The present invention provides a self-cleaning mechanism. When the long board is opened, the sliding block at the bottom of the long board will collide with the edge of the inner wall of the fixed frame of the outer wall of the photovoltaic panel, and as the long board continues to open, it is pushed by the inner wall of the fixed frame, so that the sliding block will slide backward through the sliding bar at the bottom of the long board and pull the elastic rope B to deform it. When the sliding block slides, the brush hairs are continuously pushed by the pushing rod, and the brush hairs vibrate by their own elastic force, thereby completing the self-cleaning effect of the brush hairs, avoiding the problem of secondary pollution caused by residues attached to the surface of the brush hairs when cleaning the photovoltaic panel. At the same time, when the sliding block slides at the bottom of the long board, it will drive the telescopic board to freely expand and contract. Therefore, when the long board moves, the surface of the photovoltaic panel will be directly scraped by the telescopic board, and things that are attached to the surface of the photovoltaic panel and cannot be swept out will be scraped off, and as the sliding block slides, the telescopic board will not collide with the fixed frame of the outer wall of the photovoltaic panel.

[0022] 5. The present invention is not only applicable to various household passenger cars, but also to various commercial passenger cars. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] Embodiment 1:

[0036] See also Figure 1-4 The present invention provides a technical solution: a photovoltaic power generation device on the roof of a passenger car, comprising a passenger car 1, a connecting frame 2 is fixedly connected to the top of the passenger car 1, a fixing frame 5 is fixedly connected to the top of the connecting frame 2, a photovoltaic panel 6 is fixedly connected to the inner wall of the fixing frame 5, and a wind cleaning mechanism 3 is arranged on the top of the fixing frame 5;

[0037] The wind cleaning mechanism 3 comprises:

[0038] The fixing block 301 is a circular columnar structure. One end of the fixing block 301 is fixedly connected to the top of the fixing frame 5. The outer wall of the fixing block 301 is rotatably connected to one end of the long board 302. The other end of the long board 302 is fixedly connected to an elastic rope A303. The fixing block 301 is used to connect the long board 302 and the fixing frame 5.

[0039] The guide block 306 is a circular cylindrical structure. The guide block 306 is fixedly connected to the inner side of the long plate 302. The inner side of the long plate 302 is also provided with a guide groove 305. The guide block 306 is used to change the direction of the airflow.

[0040] When the passenger car 1 is driving, the connecting frame 2 and the fixed frame 5 are driven to drive synchronously, and the photovoltaic panel 6 inside the fixed frame 5 performs photovoltaic power generation with the sun. In addition, during driving, due to the shape of the outer wall of the passenger car 1, the air will be blown from the front of the passenger car 1 along the front cover to the front windshield, and finally pass through the top of the passenger car 1, thereby guiding the wind to the top of the passenger car 1. At this time, when a large amount of wind blows through the top of the passenger car 1, it will blow the long board 302. The long board 302 is pushed by the wind to slide and rotate on the outer wall of the fixed block 301, thereby opening and closing. After the long board 302 is opened and closed, the elastic rope A303 is pulled to deform, and the surface of the photovoltaic panel 6 below is wiped by the bristles 307;

[0041] Embodiment 2:

[0042] See also Figure 1-9 On the basis of the first embodiment, the present invention provides a technical solution: one end of the elastic rope A303 is fixedly connected to the connecting column 304, one end of the connecting column 304 is fixedly connected to the top of the fixed frame 5, and the inner side of the long board 302 is fixedly connected to the bristles 307.

[0043] A magnetic block A310 is fixedly connected to the outer side of the long board 302 , a limiting rod 312 is fixedly connected to the top of the fixed frame 5 , and a magnetic block B311 is fixedly connected to the outer wall of the limiting rod 312 .

[0044] The magnetic block B311 is magnetic, and the magnetic block A310 is magnetic. The magnetism of the magnetic block B311 and the magnetic block A310 on the opposite side is magnetism of opposite poles attracting each other.

[0045] The inner wall of the fixed block 301 is provided with a ventilation groove 309, the inner wall of the ventilation groove 309 is rectangular, the inner wall of the guide block 306 is provided with a circular through groove 308, and the long plate 302 is provided with a self-cleaning mechanism 4;

[0046] After the opening and closing rotation, the long board 302 is limited by the magnetic block A310 and the magnetic block B311, and is blocked by the magnetic block B311, thereby limiting the position of the long board 302, and the magnetic block A310 and the magnetic block B311 are attracted to each other by the magnetic attraction of opposite poles, thereby completing the stable adsorption of the long board 302. Even if the vehicle speed decreases and the wind force decreases, the long board 302 will not be pulled back by the elastic force of the elastic rope A303. Only when the passenger car 1 stops driving completely and there is no wind, the long board 302 loses the wind resistance, so the elastic rope A303 is used to pull the long board 302 back. The pulling force of rope A303 is greater than the magnetic attraction between magnetic block A310 and magnetic block B311, so that the long board 302 is automatically pulled back to its original position, and the surface of photovoltaic panel 6 is cleaned again by brush 307, so that the photovoltaic power generation stability of photovoltaic panel 6 is maintained under long-term working conditions and will not be blocked by stains. In addition, the magnetic attraction between magnetic block A310 and magnetic block B311 ensures that the long board 302 will not swing back and forth under different vehicle speeds, so that the stability of passenger car 1 during driving is not affected.

[0047] And after the long board 302 is opened and closed, when the wind blows to the long board 302, it will be concentrated and circulated through the guide groove 305 opened on the inner wall of the long board 302, and enter the guide block 306, and the ventilation direction will be changed through the inner wall of the guide block 306, so as to complete the diversion and redirection of the airflow direction, so that after the long board 302 is opened and closed, the airflow will be changed by the guide block 306 to spray the airflow to the surface of the photovoltaic panel 6 after passing through the guide block 306. So that when the photovoltaic panel 6 is blown by the air directly in front, the photovoltaic panel 6 is also impacted by the several guide blocks 306 on both sides, so that the air on the surface of the photovoltaic panel 6 is turbulent, and then the dust adhering to the surface of the photovoltaic panel 6 is better taken away through the irregular airflow fluctuations, so as to complete the more efficient cleaning of the surface of the photovoltaic panel 6.

[0048] At the same time, the airflow through the guide groove 305 and the surface of the long plate 302 continues to flow into the ventilation groove 309 in the middle of the fixed block 301, so that the rear photovoltaic panel 6 is quickly sprayed with concentrated high-pressure airflow through the ventilation groove 309, so that the surface of the photovoltaic panel 6 located at the rear is also fully cleaned by the airflow, and the high-pressure airflow concentrated through the ventilation groove 309 can remove stubbornly adhered stains, avoiding the problem that the rear photovoltaic panel 6 is slightly blocked by the front;

[0049] Embodiment three:

[0050] See also Figure 1-11On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: the self-cleaning mechanism 4 includes a slide bar 403, the inner side of the long plate 302 is fixedly connected with the slide bar 403, the outer wall of the slide bar 403 is slidably connected with a sliding block 401, and the outer wall of the sliding block 401 is fixedly connected with a toggle rod 402.

[0051] One end of the slide bar 403 is fixedly connected to a stopper A404 , an outer wall of the stopper A404 is fixedly connected to an elastic rope B405 , and one end of the elastic rope B405 is fixedly connected to the outer wall of the slide block 401 .

[0052] The outer wall of the sliding block 401 is fixedly connected with a telescopic plate 406, one end of the telescopic plate 406 is fixedly connected with a stopper B407, and the outer wall of the stopper B407 is fixedly connected with the bottom of the long plate 302;

[0053] At the same time, when the long board 302 is opened, the sliding block 401 at the bottom of the long board 302 will hit the edge of the inner wall of the fixed frame 5 of the outer wall of the photovoltaic panel 6, and as the long board 302 continues to open, it is pushed by the inner wall of the fixed frame 5, so that the sliding block 401 will slide backward through the sliding bar 403 at the bottom of the long board 302, and pull the elastic rope B405 to deform it. When the sliding block 401 slides, the brush bristles 307 are continuously pushed by the toggle rod 402, and the brush bristles 307 vibrate by their own elastic force, thereby completing the brushing. The self-cleaning effect of 307 avoids the problem of secondary pollution caused by residues adhering to the surface of the bristles 307 when cleaning the photovoltaic panel 6. At the same time, when the sliding block 401 slides at the bottom of the long plate 302, it will drive the telescopic plate 406 to freely extend and retract. Therefore, when the long plate 302 moves, the surface of the photovoltaic panel 6 will be directly scraped through the telescopic plate 406, and the things that adhere to the surface of the photovoltaic panel 6 and cannot be swept out will be scraped off. Moreover, as the sliding block 401 slides, the telescopic plate 406 will not collide with the fixed frame 5 on the outer wall of the photovoltaic panel 6.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
