Description

Technical Field

[0001] This invention relates to the field of photovoltaic technology, and more particularly to a dust removal device for photovoltaic panels and a dust removal method for photovoltaic panels. Background Technology

[0002] A photovoltaic (PV) panel is a device that directly converts solar energy into electrical energy. Its power generation efficiency is directly related to sunlight. However, PV panels can only receive sunlight when they are in an external environment. Being in an external environment will cause a lot of dust and debris to accumulate on the surface of the PV panel. If the dust and other debris on the surface of the PV panel are not cleaned in time, they will block the absorption of sunlight and significantly reduce the power generation efficiency of the PV panel. Therefore, cleaning PV panels has always been a problem that has hindered the development of PV panels.

[0003] Currently, the installation of photovoltaic (PV) panels is widespread in rural areas. However, during busy farming seasons, rural areas generate a lot of dust, especially on sandy or gravelly surfaces. This dust is easily blown by the wind, resulting in a significant dust accumulation on the PV panels. Furthermore, the widespread use of earthen stoves in rural areas produces fumes that also adhere to the PV panels. If this dust is not cleaned regularly, it will affect the PV panels' absorption of sunlight, severely impacting solar power generation. Current technologies for cleaning PV panels use a broad-area cleaning brush, which cannot perform targeted cleaning or effectively adjust the brush's position, thus reducing cleaning efficiency. Therefore, there is an urgent need for a dust removal device that allows for easy adjustment of the cleaning brush position while cleaning the PV panels. Summary of the Invention

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] Please refer to Figures 1-7 As shown, the present invention provides a photovoltaic panel dust removal device, including a photovoltaic panel 1 and a slide 2 arranged parallel to the photovoltaic panel 1, the slide 2 being located above the photovoltaic panel 1;

[0034] The slide 2 is fixedly connected to a first connecting plate 3 at one end and a second connecting plate 6 at the other end. A threaded rod 5 is rotatably provided between the second connecting plate 6 and the first connecting plate 3.

[0035] Both sides of the photovoltaic panel 1 are fixedly connected to slide rails 11;

[0036] The first connecting plate 3 and the second connecting plate 6 are respectively provided with a first power mechanism and a second power mechanism to drive the slide 2 to slide.

[0037] Both ends of the threaded rod 5 are equipped with adjustment mechanisms that allow the threaded rod 5 to be intermittently linked with the first power mechanism and the second power mechanism. The first power mechanism and the second power mechanism drive the threaded rod 5 to rotate forward and reverse, respectively.

[0038] The threaded rod 5 is externally threaded with a cleaning mechanism for cleaning the surface of the photovoltaic panel 1, and the cleaning mechanism is set in an oscillating manner.

[0039] In this embodiment, the photovoltaic panel 1 and the slide 2 are arranged in parallel. The photovoltaic panel 1 is relatively long and is driven by the first and second power mechanisms of this solution. This allows the cleaning mechanism to slide on the photovoltaic panel 1, thereby cleaning the dust on the photovoltaic panel 1. There is no need to use a push rod to push the cleaning mechanism to move, which improves the applicability. The cleaning mechanism is set in a swinging manner, which makes it easy for the cleaning mechanism to come into contact with the photovoltaic panel 1. During the movement of the cleaning mechanism, it can scrape off the adhesives adhering to the photovoltaic panel 1, effectively cleaning the dust on the photovoltaic panel 1 and scraping off the adhesives.

[0040] The first and second power mechanisms drive the threaded rod 5 to rotate forward and reverse, respectively. The adjusting mechanism can adjust the position of the threaded rod 5 so that it is intermittently linked with the first and second power mechanisms, thereby enabling the threaded rod 5 to rotate forward and reverse. The threaded rod 5 is threadedly connected to the cleaning mechanism, so the cleaning mechanism can slide along the threaded rod 5 through the forward and reverse rotation of the threaded rod 5, thereby enabling the cleaning mechanism to slide on the photovoltaic panel 1 and effectively clean the photovoltaic panel 1. The position of the cleaning mechanism can be adjusted in the forward direction, improving the cleaning efficiency of the photovoltaic panel 1.

[0041] By adjusting the mechanism, the slide 2 can rotate the threaded rod 5 in both directions during its forward movement, thereby effectively adjusting the position of the cleaning mechanism. This allows for directional cleaning of the photovoltaic panel 1, and the swinging motion of the cleaning mechanism helps to scrape off adhering substances during movement, effectively cleaning dust and adhering substances from the photovoltaic panel 1 and improving cleaning efficiency.

[0042] The first power mechanism includes a first rotary motor 32, a first rotating rod 33, a first roller 331, a second gear 34, a second roller 41, and a belt 411. The first rotary motor 32 is fixedly mounted on one side of the first connecting plate 3. The power output end of the first rotary motor 32 passes through the first connecting plate 3 and is fixedly connected to a connecting rod 4. The second gear 34 and the second roller 41 are both fixedly mounted around the connecting rod 4. The second roller 41 is mounted above the first roller 331. The belt 411 is sleeved around the first roller 331 and the second roller 41. The first roller 331 is fixedly mounted around the first rotating rod 33. The first rotating rod 33 is rotatably connected to the first connecting plate 3. One end of the first rotating rod 33 is fixedly connected to the second gear 34.

[0043] The second power mechanism includes a second rotary motor 61, a second rotating rod 611, a fourth gear 62, and a fifth gear 63. The second rotary motor 61 is fixedly mounted on one side of the second connecting plate 6. The power output end of the second rotary motor 61 passes through the second connecting plate 6 and is fixedly connected to the second rotating rod 611. The fourth gear 62 is fixedly mounted on the periphery of the second rotating rod 611. The fifth gear 63 is rotatably mounted on the second connecting plate 6 and meshes with the fourth gear 62. The first gear 332 is fixedly connected to one end of both the second rotating rod 611 and the first rotating rod 33. A rack 111 that meshes with the first gear 332 is fixedly mounted on the slide rail frame 11.

[0044] The starting of the first rotary motor 32 and the second rotary motor 61 drives the connecting rod 4 and the second rotating rod 611 to rotate. The connecting rod 4 drives the second gear 34 and the second roller 41 to rotate. The second roller 41 drives the belt 411 to rotate. The belt 411 drives the first roller 331 to rotate, so that the first roller 331 and the second roller 41 rotate in the same direction. The first roller 331 drives the first rotating rod 33 to rotate. During the rotation of the second rotating rod 611, it drives the fourth gear 62 to rotate. The fourth gear 62 drives the fifth gear 63 to rotate, so that the first rotating rod 33 and the second rotating rod 611 drive the first gear 332 to rotate. The first gear 332 meshes with the rack 111, so that the first gear 332 moves along the rack 111. As the first gear 332 moves, the first connecting plate 3 and the second connecting plate 6 move, thereby driving the slide 2 to move.

[0045] Among them, the first rotary motor 32 and the second rotary motor 61 are the same type of motor, which can be started and stopped at the same time during startup, so as to enable the slide 2 to move forward, so as to be suitable for the photovoltaic panel 1 with a longer assembly.

[0046] The adjustment mechanism includes a first electric telescopic rod 311, an adjustment rod 51, a third gear 52, and a sixth gear 9. The adjustment rod 51 is rotatably mounted at both ends of the threaded rod 5. The adjustment rod 51 has a square structure. The two adjustment rods 51 are slidably connected to the first connecting plate 3 and the second connecting plate 6, respectively. The adjustment rod 51 is fixedly connected to the first electric telescopic rod 311. A support frame 31 fixedly connected to the first electric telescopic rod 311 is fixedly connected to the first connecting plate 3. The third gear 52 and the sixth gear 9 are both fixedly connected to the periphery of the threaded rod 5, and the third gear 52 and the sixth gear 9 are respectively located on the periphery of both ends of the threaded rod 5.

[0047] The third gear 52 and the sixth gear 9 are respectively located on the outer periphery of both ends of the threaded rod 5. The activation of the first electric telescopic rod 311 drives the adjusting rod 51 to slide, which in turn moves the threaded rod 5. The threaded rod 5 then drives the third gear 52 and the sixth gear 9 to slide. The movement range of the third gear 52 and the sixth gear 9 is divided into three types:

[0048] The first method involves engaging the third gear 52 with the second gear 34, at which point the sixth gear 9 disengages from the fifth gear 63. The second gear 34 then drives the third gear 52 to rotate. This rotation causes the third gear 52 to rotate in the opposite direction to the second gear 34. Since the first roller 331 and the second roller 41 are driven to rotate via the belt 411, they rotate in the same direction. Therefore, the first gear 332 rotates in the opposite direction to the third gear 52. During forward movement, when the second gear 34 engages with the third gear 52, the threaded rod 5 rotates in one direction, ensuring the rotation of the threaded rod 5.

[0049] The second method involves engaging the sixth gear 9 with the fifth gear 63. At this time, the third gear 52 disengages from the second gear 34. The fifth gear 63 then drives the sixth gear 9 to rotate. This rotation causes the sixth gear 9 to rotate in the opposite direction to the fifth gear 63. Since the fifth gear 63 engages with the fourth gear 62, their rotation directions are also opposite. Therefore, the sixth gear 9 and the fourth gear 62 rotate in the same direction. During the forward movement, when the sixth gear 9 engages with the fifth gear 63, the threaded rod 5 rotates in the opposite direction, ensuring the rotation of the threaded rod 5. This method, along with the first method, ensures that the threaded rod 5 alternates between forward and reverse rotation during the forward movement, facilitating changes in the position of the cleaning mechanism and increasing the cleaning range.

[0050] The third method involves disengaging the sixth gear 9 from the fifth gear 63 and disengaging the third gear 52 from the second gear 34. At this time, the threaded rod 5 is stationary. As it moves forward, the cleaning mechanism moves in the direction of the slide 2, thus making a lateral movement.

[0051] The replacement of the above three states can effectively ensure the movement range of the cleaning mechanism, effectively adjust the position of the cleaning mechanism, and improve the cleaning range.

[0052] One approach is to fix a water tank at the top of the slide 2 and install a nozzle (not shown in the attached diagram) so that water is sprayed from the nozzle onto the top of the photovoltaic panel 1. Due to the tilt of the photovoltaic panel 1, the sprayed water can slide downwards along the tilt of the photovoltaic panel 1 to rinse and clean the photovoltaic panel 1. The cleaning effect can be improved by combining this with the cleaning mechanism.

[0053] The cleaning mechanism includes a slider 8, a support rod 81, a movable plate 7, and a cleaning brush 73. The bottom surface of the slide 2 is provided with a second limiting groove 21 for the slider 8 to slide. The slider 8 is threadedly connected to the threaded rod 5. The bottom end of the slider 8 is fixedly connected to the support rod 81. A ball bearing 74 is rotatably connected between the support rod 81 and the movable plate 7. The bottom surface of the movable plate 7 is provided with a slot 72 for the cleaning brush 73 to engage. The cleaning brush 73 has a ring-shaped structure.

[0054] A second electric telescopic rod 811 is provided between the support rod 81 and the movable plate 7. One end of the second electric telescopic rod 811 is set on the support rod 81, and the other end is rotatably connected to the movable plate 7 through a lifting lug.

[0055] Scrapers 71 are fixedly installed on both sides of the bottom surface of the movable plate 7.

[0056] By setting the slider 8, the slider 8 is threadedly connected to the threaded rod 5, so that the slider 8 can be driven to slide by the rotation of the threaded rod 5. The slider 8 drives the support rod 81 to move, the support rod 81 drives the ball 74 and the moving plate 7 to move, and the moving plate 7 drives the cleaning brush 73 to move, so that the cleaning brush 73 cleans the dust on the photovoltaic panel 1 during the movement.

[0057] The second electric telescopic rod 811 can drive the moving plate 7 to rotate around the ball 74, making the moving plate 7 tilted. At this time, the cleaning brush 73 can be pressed on the photovoltaic panel 1, and the scraper 71 can be in contact with the photovoltaic panel 1 to scrape off the adhesive on the photovoltaic panel 1 and clean the adhesive.

[0058] A support mechanism is provided between the slide 2 and the slide rail 11. The support mechanism includes a limiting rod 22, which has a U-shaped structure. The top end of the limiting rod 22 is fixedly connected to the bottom surface of the slide 2. A first limiting groove 112 is provided on the slide rail 11 for the bottom end of the limiting rod 22 to slide.

[0059] The setting of limit rod 22 increases the stability of carriage 2 and prevents derailment during forward movement.

[0060] The method for dust removal from photovoltaic panels includes the following steps:

[0061] S1: Walking: By starting the first rotary motor 32 and the second rotary motor 61, the first gear 332 and the fourth gear 62 can be rotated. Under the action of the rack 111, the first gear 332 and the fourth gear 62 drive the slide 2 to move above the photovoltaic panel 1 while rotating.

[0062] S2: Adjustment: By activating the first electric telescopic rod 311, three states of the threaded rod 5 can be achieved, including:

[0063] First type: The threaded rod 5 rotates in one direction;

[0064] The second method: the threaded rod 5 rotates in another direction;

[0065] The third option: the threaded rod 5 remains stationary;

[0066] The first and second types can arbitrarily change the position of the movable plate 7, while the third type can ensure the horizontal movement of the movable plate 7.

[0067] S3: Cleaning: As the moving plate 7 moves, the cleaning brush 73 can sweep the dust off the photovoltaic panel 1;

[0068] S4: Scraping: By activating the second electric telescopic rod 811, the moving plate 7 can be tilted, and one side of the cleaning brush 73 is pressed on the photovoltaic panel 1, so that the scraper 71 contacts the photovoltaic panel 1, making it easy to scrape off the adhesive and clean the dust and adhesive on the photovoltaic panel 1.

[0069] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
