[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] The present invention provides a self-cleaning lightning protection photovoltaic component, such as Figures 1 to 8As shown, it includes an outer frame 1, which is set to a salt-spray-resistant aluminum alloy frame, and a photovoltaic panel 2 placed on the top surface of the outer frame 1, and a UV-resistant POE film is adhered to the surface of the photovoltaic panel 2. The top surface of the outer frame 1 is provided with a cleaning structure for cleaning the photovoltaic panel 2, and the cleaning structure includes: an inner frame 3, a brush plate 4, a buffer part, a clamping component, a protruding rod 5, a movable frame 6 and a lifting component; the inner frame 3 is at the top of the photovoltaic panel 2, and the clamping component makes the brush plate 4 correspondingly inserted into the vertical groove 301 of the inner frame 3, and the buffer part makes the bottom end of the brush plate 4 fit with the top surface of the photovoltaic panel 2, and protruding rods 5 are fixed at both ends of the inner frame 3, and movable frames 6 are provided on both sides of the top of the outer frame 1, and the two protruding rods 5 correspond one-to-one to the two movable frames 6. The protruding rods 5 are inserted into the inner groove 601 of the movable frame 6, and the lifting component makes the protruding rods 5 move up and down inside the inner groove 601; a driving structure for driving the movable frame 6 to move back and forth is provided inside the outer frame 1. The bottom of the outer frame 1 is installed on the ground through a bracket. The elastic force of the buffer part makes the bristles on the bottom of the brush plate 4 correspond to the top surface of the outer frame 1 and the top surface of the photovoltaic panel 2. The driving structure makes the movable frame 6 move on the top surface of the outer frame 1. The moving movable frame 6 uses the protruding rod 5 to push the inner frame 3 to move synchronously. The inner frame 3 drives the bristles of the brush plate 4 to move on the top surface of the photovoltaic panel 2 through the clamping component. The reciprocating brush plate 4 cooperates to scrape the dust on the top surface of the photovoltaic panel 2.

[0020] Specifically, after the brush plate 4 is inserted into the vertical groove 301 of the inner frame 3, the clamping component cooperates with the buffer part to confine the brush plate 4 inside the vertical groove 301, and the inner frame 3 and the brush plate 4 are moved downward by the lifting component until the bristles on the bottom surface of the brush plate 4 contact the top surface of the photovoltaic panel 2. The inner frame 3 that continues to move downward uses the vertical groove 301 to move downward on the surface of the brush plate 4. The inner frame 3 that moves downward cooperates to pull the buffer part, and the elastic force of the buffer part makes the bristles of the brush plate 4 close to the top surface of the photovoltaic panel 2.

[0021] In this embodiment, the brush plate 4 is limited by the snap-fitting components. When the driving structure utilizes the movable frame 6 to enable the inner frame 3 to drive the brush plate 4 to move, the elastic force of the buffer portion causes the bristles of the brush plate 4 to adhere tightly to the top surface of the photovoltaic panel 2, so that the movable brush plate 4 uses the bristles to scrape the dust on the top surface of the photovoltaic panel 2, thereby ensuring the cleaning effect of the photovoltaic panel 2.

[0022] A lightning protection module 24 is fixed on the side of the outer frame 1. The lightning protection module 24 is composed of a gas discharge tube and a varistor, and the lightning protection module 24 is synchronously packaged by an RDS self-cleaning nano-coating to achieve coordinated anti-fouling and electrical protection of the entire photovoltaic component surface, thereby reducing the risk of lightning damage to the photovoltaic panel 2.

[0023] exist Figures 2 to 4In the embodiment, the clamping components include: a limiting rod 7, a first rotating sleeve 8, a protruding strip 9, a circular plate 10, a side strip 11 and a spring piece 12; the limiting rod 7 is fixed at the four corners of the top surface of the inner frame 3, the limiting rod 7 is arranged vertically, the first rotating sleeve 8 is rotatably sleeved on the surface of the limiting rod 7, the circumferential outer side surface of the first rotating sleeve 8 is fixed with a protruding strip 9, the top of the limiting rod 7 is fixed with a circular plate 10, and the circumferential outer side surface of the circular plate 10 is fixed with a side strip 11, the side surface of the side strip 11 is connected to the outer side surface of the protruding strip 9 by a spring piece 12, the elastic force of the spring piece 12 causes the first rotating sleeve 8 to rotate through the protruding strip 9, and the rotating protruding strip 9 is clamped inside the card slot 401 of the brush plate 4. The first rotating sleeve 8 is rotated, and the first rotating sleeve 8 rotates on the surface of the limiting rod 7, and the rotating first rotating sleeve 8 causes the protruding strip 9 to approach the side strip 11. The rotating protruding strip 9 cooperates with the side strip 11 to squeeze the spring piece 12, and the two opposing protruding strips 9 separate from each other. Insert the brush plate 4 into the vertical slot 301 of the inner frame 3, and move the brush plate 4 downward in the vertical slot 301 until the slot 401 of the brush plate 4 corresponds to the ridge 9. Release the torsional force applied to the first rotating sleeve 8, and the elastic force of the spring piece 12 causes the ridge 9 to rotate in the opposite direction. The rotating ridge 9 causes the first rotating sleeve 8 to rotate in the opposite direction on the surface of the limiting rod 7 until the inner end of the ridge 9 is engaged in the slot 401. The limitation of the brush plate 4 is completed through the limitation of multiple ridges 9.

[0024] Specifically, after the elastic force of the spring piece 12 causes the inner end of the protrusion 9 to be clamped in the slot 401, the cleaning structure uses the brush plate 4 to clean the photovoltaic panel 2 for a long time, and then rotates the first rotating sleeve 8. The rotating first rotating sleeve 8 uses the protrusion 9 to squeeze the spring piece 12, and the inner end of the rotating protrusion 9 is moved out from the slot 401. The brush plate 4 is pulled out from the top of the vertical groove 301, and the new brush plate 4 is vertically inserted into the vertical groove 301, and the new brush plate 4 is limited by the clamping component.

[0025] The buffer portion is configured as a spring 13, which is sleeved on the surface of the limiting rod 7. The bottom end of the spring 13 is connected to the top surface of the first rotating sleeve 8, and the top end of the spring 13 is in contact with the bottom surface of the circular plate 10. After the brush plate 4 is installed inside the vertical groove 301, the lifting component causes the inner frame 3 and the brush plate 4 to move downward until the bristles at the bottom end of the brush plate 4 are in contact with the top surface of the photovoltaic panel 2. The inner frame 3 continues to move downward. Since the photovoltaic panel 2 limits the brush plate 4, the inner frame 3 moves downward on the surface of the brush plate 4 using the vertical groove 301. The brush plate 4 uses the convex strip 9 to limit the first rotating sleeve 8. The downwardly moving inner frame 3 drives the limiting rod 7 downward. The downwardly moving limiting rod 7 uses the circular plate 10 to squeeze the spring 13 at the top of the first rotating sleeve 8. The elastic force of the spring 13 is applied to the brush plate 4 through the clamping component, thereby improving the close contact effect between the bristles and the top surface of the photovoltaic panel 2.

[0026] In this embodiment, the brush plates 4 of different heights can be conveniently replaced inside the vertical groove 301 through the snap-fitting components. Under the elastic force limitation of the buffer part, the adhesion effect between the bristles and the top surface of the photovoltaic panel 2 is improved. At this time, the moving brush plate 4 uses the bristles to quickly clean the top surface of the photovoltaic panel 2.

[0027] When the bristles of the horizontally moving brush plate 4 move to the top surface of the outer frame 1, the brush plate 4 is pulled upward, and the upwardly moving brush plate 4 uses the convex strip 9 to drive the first rotating sleeve 8 to move upward, and the upwardly moving first rotating sleeve 8 cooperates with the circular plate 10 to squeeze the spring 13 until the bristles of the brush plate 4 are away from the outer frame 1. The tension applied to the brush plate 4 is released, and the elastic force of the spring 13 causes the brush plate 4 to move downward quickly, and the brush plate 4 cooperates with the outer frame 1 to impact the bristles, and the dust inside the bristles is quickly removed by multiple impacts to avoid excessive accumulation of dust inside the bristles.

[0028] exist Figure 2 、 Figures 5 to 7 In the figure, the lifting component includes a rotating rod 14, a second rotating sleeve 15, and an arc-shaped bracket 16. The rotating rod 14 vertically passes through the center of the top surface of the moving frame 6. The second rotating sleeve 15 is fixed to the top of the rotating rod 14, and two opposing arc-shaped brackets 16 are fixed to the top surface of the moving frame 6. The second rotating sleeve 15 is rotatably sleeved on the outside of the two arc-shaped brackets 16. The bottom end of the rotating rod 14 extends into the interior of the moving frame 6 and spirally passes through the center of the protruding rod 5. The surface of the protruding rod 5 is provided with a screw hole 501. The bottom end of the rotating rod 14 is screwed into the screw hole 501. The rotating rotating rod 14 uses the screw hole 501 to move the protruding rod 5 up and down within the inner groove 601. After the brush plate 4 is limited by the clamping component, the second rotating sleeve 15 is rotated. Since the movable frame 6 uses two arc-shaped clamping frames 16 to limit the second rotating sleeve 15, the rotating second rotating sleeve 15 causes the rotating rod 14 to rotate inside the movable frame 6. Since the bottom end of the rotating rod 14 spirally penetrates the screw hole 501 of the protruding rod 5, the rotating rotating rod 14 and the screw hole 501 are spirally matched, thereby causing the protruding rod 5 to move up and down inside the inner groove 601 of the movable frame 6.

[0029] Specifically, when the rotating rod 14 causes the protruding rod 5 to move downward inside the inner groove 601, the downwardly moving protruding rod 5 drives the inner frame 3 to move downward synchronously. At this time, the inner frame 3 uses the clamping component to drive the brush plate 4 to move downward synchronously. Under the elastic force limitation of the buffer part, the bristles of the brush plate 4 are tightly attached to the top surface of the photovoltaic panel 2.

[0030] exist Figure 1 、 Figure 7 and Figure 8In the embodiment, the outer frame 1 is provided with side frames 17 fixed at the four corners, and the driving structure includes: side rods 18, gears 19, conveyor belts 20, and baffles 21. Side rods 18 are provided at both ends of the outer frame 1. Two gears 19 are fixed to the outer circumference of the side rods 18. The gears 19 are located inside the side frames 17. The two side rods 18 are arranged opposite each other. The conveyor belts 20 are rotatably connected to the outer sides of two adjacent gears 19. Baffles 21 are fixed at both ends of the side rods 18. The baffles 21 are located outside the side frames 17 and are connected to the output end of the stepper motor. The top surface of the outer frame 1 is provided with two parallel chutes 22. The two chutes 22 correspond to the two conveyor belts 20 one-to-one. The top surface of the conveyor belts 20 is connected to the bottom surface of the movable frame 6 by means of struts 23. The rotating conveyor belts 20 drive the movable frame 6 to move back and forth by means of struts 23, and the struts 23 move inside the chutes 22. Start the stepper motor, and the output end of the stepper motor causes the baffle 21 to rotate. The rotating baffle 21 uses the side rod 18 to rotate the gear 19. The rotating gear 19 uses the conveyor belt 20 to make the adjacent side rods 18 rotate synchronously. The rotating conveyor belt 20 uses the support bar 23 to drive the movable frame 6 to move. At this time, the support bar 23 moves inside the slide groove 22, and the bottom surface of the movable frame 6 is in contact with the top surface of the outer frame 1.

[0031] Specifically, when the side rod 18 rotates, the rotating side rod 18 causes the gear 19 to rotate inside the side frame 17. The rotating gear 19 uses the conveyor belt 20 to make the adjacent side rods 18 rotate synchronously. The conveyor belt 20 is used to ensure the synchronous rotation effect of the two side rods 18. At this time, the bidirectional rotation of the conveyor belt 20 can make the movable frame 6 move back and forth on the top surface of the outer frame 1. The reciprocating movable frame 6 uses the brush plate 4 to scrape the dust on the top surface of the photovoltaic panel 2 back and forth.

[0032] Working principle of the present invention: Reference Figures 1 to 8 As shown, the first rotating sleeve 8 is rotated, and the first rotating sleeve 8 rotates on the surface of the limiting rod 7. The rotating first rotating sleeve 8 causes the protrusion 9 to approach the side strip 11. The rotating protrusion 9 and the side strip 11 cooperate to squeeze the elastic piece 12, and the two opposing protrusions 9 separate from each other. The brush plate 4 is inserted into the vertical slot 301 of the inner frame 3. The brush plate 4 moves downward inside the vertical slot 301 until the groove 401 of the brush plate 4 corresponds to the protrusion 9. The torsional force applied to the first rotating sleeve 8 is released. The elastic force of the elastic piece 12 causes the protrusion 9 to rotate in the opposite direction. The rotating protrusion 9 causes the first rotating sleeve 8 to rotate in the opposite direction on the surface of the limiting rod 7 until the inner end of the protrusion 9 is engaged in the groove 401. Through the restriction of multiple protrusions 9, the restriction of the brush plate 4 is completed.

[0033] When the second rotating sleeve 15 is rotated, the moving frame 6 uses two arc-shaped brackets 16 to limit the second rotating sleeve 15. The rotating second rotating sleeve 15 causes the rotating rod 14 to rotate inside the moving frame 6. When the rotating rotating rod 14 causes the convex rod 5 to move down inside the inner groove 601, the downwardly moving convex rod 5 drives the inner frame 3 to move down synchronously. At this time, the inner frame 3 uses the clamping component to drive the brush plate 4 to move down synchronously until the bristles at the bottom of the brush plate 4 are in contact with the top surface of the photovoltaic panel 2. The inner frame 3 continues to move down. Since the photovoltaic panel 2 limits the brush plate 4, the inner frame 3 uses the vertical groove 301 to move down on the surface of the brush plate 4, and the brush plate 4 uses the convex strip 9 to limit the first rotating sleeve 8. The downwardly moving inner frame 3 drives the limiting rod 7 to move down. The downwardly moving limiting rod 7 uses the circular plate 10 to squeeze the spring 13 at the top of the first rotating sleeve 8. The elastic force of the spring 13 is applied to the brush plate 4 through the clamping component, thereby improving the close contact effect between the bristles and the top surface of the photovoltaic panel 2.

[0034] Start the stepper motor, and the output end of the stepper motor causes the baffle 21 to rotate. The rotating baffle 21 uses the side rod 18 to rotate the gear 19. The rotating gear 19 uses the conveyor belt 20 to make the adjacent side rods 18 rotate synchronously. The conveyor belt 20 is used to ensure the synchronous rotation effect of the two side rods 18. At this time, the bidirectional rotation of the conveyor belt 20 can make the movable frame 6 reciprocate on the top surface of the outer frame 1. The reciprocating movable frame 6 uses the brush plate 4 to reciprocate and scrape the dust on the top surface of the photovoltaic panel 2.

[0035] After the cleaning structure uses the brush plate 4 to clean the photovoltaic panel 2 for a long time, the first rotating sleeve 8 is rotated, and the rotating first rotating sleeve 8 uses the convex strip 9 to squeeze the spring piece 12. The inner end of the rotating convex strip 9 is moved out from the inside of the card slot 401, and the brush plate 4 is pulled out from the top of the vertical slot 301. The new brush plate 4 is vertically inserted into the vertical slot 301, and the new brush plate 4 is limited by the card connection component.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
