[0003] A Chinese patent with the publication number CN113992130A discloses an outdoor photovoltaic module based on sunlight reflection that can improve the light energy absorption effect, including a base. A group of evenly arranged round holes are provided on the base. The characteristics are that: on the upper side of the base, motors are fixedly connected through symmetric L-shaped brackets. The motors are fixedly connected to the middle of one side of a support rod through a cross bar. Both ends of the support rod are respectively fixedly connected to ball grooves, and each ball groove is respectively matched with a spherical ball.

[0004] In the prior art, after a photovoltaic panel working outdoors has worked for a long time, due to the increase in air pollution and the number of dust in the air, there will be dust impurities on the surface of the photovoltaic panel. Currently, the cleaning of the surface of the photovoltaic panel often relies on the inclination angle during the installation of the photovoltaic panel itself. And some of the impurities falling on the surface of the photovoltaic panel contain moisture, which will adhere to the surface of the photovoltaic panel, resulting in affecting the contact area between the photovoltaic panel and sunlight, reducing the light energy absorption effect, and affecting the conversion efficiency.

Detailed Embodiments

[0030] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0031] Embodiment 1

[0032] As Figures 1 to 2As shown in the figure, an outdoor photovoltaic module capable of improving the light energy absorption effect according to an embodiment of the present invention includes a photovoltaic panel 1; a fixed outer shell 11 is fixedly connected to the outside of the photovoltaic panel 1; a water leakage hole 12 is provided on one side wall of the fixed outer shell 11; first chutes 13 are provided on the corresponding side walls of the fixed outer shell 11 on both sides of the water leakage hole 12; a storage barrel 14 is fixedly connected to the side wall of the photovoltaic panel 1 away from the water leakage hole 12; a film 15 is wound inside the storage barrel 14 through a torsion spring; the film 15 slides inside the first chutes 13; a second rotating shaft 18 is hinged above the water leakage hole 12 inside the side wall of the photovoltaic panel 1; the second rotating shaft 18 is rotated by a motor; the other end of the film 15 contacts the second rotating shaft 18 through a connecting rope; a first rotating shaft 16 is rotatably connected to the side wall of the film 15; a plurality of cleaning plates 17 are fixedly connected to the side wall of the first rotating shaft 16; during operation, after the staff completes the installation of the photovoltaic panel 1, after long-term use, there are often dust and impurities on the photovoltaic panel 1, which will affect the light energy absorption effect. At this time, in the face of rainy weather, after the photovoltaic panel 1 is washed by rain, the rainwater will carry away some dust and discharge it through the water leakage hole 12. At this time, some of the dust adhered to the photovoltaic panel 1 is not easy to be washed away. At this time, the central processor controls the second rotating shaft 18 in an area to rotate, driving the film 15 to move inside the first chutes 13. Under the action of the rain impact, the first rotating shaft 16 will rotate, so that the cleaning plates 17 clean the impurities adhered above the photovoltaic panel 1. Under the continuous forward and reverse rotation of the second rotating shaft 18, a plurality of first rotating shafts 16 are driven to move back and forth above the photovoltaic panel 1. By using the rotation of the first rotating shaft 16, the central processor can clean the photovoltaic panels 1 in an area at the same time. Because there are a lot of dust and impurities on the surface of the photovoltaic panel 1, it will affect the direct contact area of the sunlight on the surface of the photovoltaic panel 1, resulting in the influence of the light energy absorption effect. By using the rotation of the first rotating shaft 16 to drive the cleaning plates 17, the adhered impurities that cannot be removed by rain washing on the surface of the photovoltaic panel 1 are reduced, and the photoelectric conversion efficiency of the photovoltaic panel with impurities is reduced compared with that of the clean photovoltaic panel due to the presence of impurities.

[0033] As Figures 2 to 4As shown, multiple groups of water diversion grooves 2 are provided on the side wall of the film covering 15; a second sliding groove 21 is provided at the bottom end of the cleaning plate 17; a scraping plate 22 is slidably connected inside the second sliding groove 21; a water passing hole 23 is provided on the side wall of the cleaning plate 17; the water passing hole 23 communicates with the second sliding groove 21; a water leakage groove 24 is provided at the top end of the scraping plate 22; during operation, when water flows through the film covering 15, part of the water flows into the water passing hole 23 and the surface of the photovoltaic panel 1 through the water diversion groove 2. After the water enters the water passing hole 23, it will impact the scraping plate 22 and drive the scraping plate 22 to move. At this time, the rotation of the first rotating shaft 16 drives the scraping plate 22 that moves out of the second sliding groove 21 to contact the surface of the photovoltaic panel 1. By providing the water passing hole 23, water can enter to push the scraping plate 22, driving the scraping plate 22 to contact the photovoltaic panel 1 according to the depth of the photovoltaic panel 1. While increasing the adaptability of the device, it can scrape off the dust existing on the photovoltaic panel 1, and cooperate with the impact of water flow to reduce the residue of dust and reduce the influence of dust on the light energy absorption effect.

[0034] As Figures 4 to 5 shown, a limiting block 3 is fixedly connected to the inner side wall of the second sliding groove 21 near the water passing hole 23; a third rotating shaft 31 is rotatably connected to the side wall of the second sliding groove 21 corresponding to the side wall of the limiting block 3; a sealing plate 32 is fixedly connected to the side wall of the third rotating shaft 31; a sealing groove 33 is provided at the corresponding position of the limiting block 3 and the sealing plate 32; during operation, after the water enters the second sliding groove 21 through the water passing hole 23 and the scraping plate 22 moves downward under the impact of water flow and contacts the top end of the photovoltaic panel 1, the scraping plate 22 will receive an upward reaction force, driving the water to move upward. At this time, the water drives the sealing plate 32 to move so that it fits on the sealing groove 33, preventing the water from passing through and slowing down the movement of the scraping plate 22. By using the contact between the sealing plate 32 and the sealing groove 33, the passage of water can be reduced, the friction force between the scraping plate 22 and the surface of the photovoltaic panel 1 can be increased, and the dust adhering to the top surface of the photovoltaic panel 1 can be scraped off, reducing the reduction of the light energy absorption effect of the photovoltaic panel 1 due to dust adhesion and affecting the power generation efficiency.

[0035] As Figure 5As shown, a support plate 4 is fixedly connected to the side wall of the second chute 21 away from the limit block 3; the side wall of the sealing plate 32 is in contact with the top surface of the support plate 4; a connecting plate 41 is fixedly connected to the side wall of the second chute 21 above the sealing plate 32; the connecting plate 41 is elastic; a limit ball 42 is fixedly connected to the bottom end of the connecting plate 41; a plurality of limit grooves 43 are formed in the side wall of the sealing plate 32 away from the support plate 4; during operation, when the water flow presses the sealing plate 32, the sealing plate 32 will move above the support plate 4, and the position of the sealing plate 32 itself is maintained by the support of the support plate 4. When the scraper 22 contacts the surface of the photovoltaic panel 1, the impact force generated causes the sealing plate 32 to move upward, driving the contact between the limit groove 43 formed in the side wall of the sealing plate 32 and the limit ball 42, and temporarily sealing the third rotating shaft 31. By using the contact between the limit ball 42 and the limit groove 43, the position where the third rotating shaft 31 is located can be sealed for a short time, reducing the water flow passing through the rotation gap of the third rotating shaft 31, resulting in insufficient pressure on the scraper 22 and reducing the cleaning effect of the scraper 22 on the surface of the photovoltaic panel 1.

[0036] As Figure 6 shown, a pair of first magnets 5 are fixedly connected to the side wall of the second chute 21 near the bottom end; a fourth rotating shaft 51 is rotatably connected to the corresponding side walls of the scraper 22; the fourth rotating shaft 51 and the scraper 22 are connected by a torsion spring; a second magnet 52 is fixedly connected to the side wall of the fourth rotating shaft 51; the fourth rotating shaft 51 and the second magnet 52 repel each other magnetically; during operation, during the movement of the scraper 22, after the second magnet 52 exits the range of the second chute 21, the second magnet 52 unfolds outward under the action of the torsion spring of the fourth rotating shaft 51, and cooperates with the scraper 22 to scrape the surface of the photovoltaic panel 1. When the film 15 is recycled later, the scraper 22 completely enters the second chute 21 under the external pressure. Under the repulsive magnetic force between the first magnet 5 and the second magnet 52, the second magnet 52 is pressed against the side wall of the scraper 22. By using the torsion spring of the fourth rotating shaft 51 to drive the second magnet 52 to unfold outward, the contact area between the scraper 22 and the surface of the photovoltaic panel 1 can be further increased, improving the cleaning effect. At the same time, the repulsive magnetic force between the first magnet 5 and the second magnet 52 can reduce the contact between the second magnet 52 and the side wall of the second chute 21, preventing jamming during the movement.

[0037] As Figure 6As shown in the figure, a pair of first elastic ropes 6 are fixedly connected to the corresponding side walls of the pair of first magnets 5; the other ends of the pair of first elastic ropes 6 are respectively fixedly connected to the side walls of a pair of second magnets 52; a plurality of groups of first impact balls 61 are arranged on the surface of the first elastic rope 6 close to the bottom end of the second sliding groove 21; the first impact balls 61 and the first elastic rope 6 are connected by connecting ropes; during operation, when the scraping plate 22 moves under the push of water, the first elastic rope 6 will be pulled, driving the second magnet 52 to expand outwards, increasing the contact area with the top surface of the photovoltaic panel 1. At the same time, under the elastic action of the first elastic rope 6, the scraping plate 22 can be driven to recover and reset, driving the first impact balls 61 existing on the first elastic rope 6 to collide with each other. The elasticity of the first elastic rope 6 itself can assist the second magnet 52 to expand outwards, increasing the contact area with the surface of the photovoltaic panel 1, removing the dust existing on the photovoltaic panel 1. At the same time, the mutual collision between the plurality of groups of first impact balls 61 can use the vibration effect to reduce the adhesion of the dust scraped off by the second magnet 52.

[0038] As Figures 3 to 7 shown, a plurality of groups of buffer plates 7 are arranged at the top end of the film covering 15; the plurality of groups of buffer plates 7 are connected by a fifth rotating shaft 71; a plurality of groups of rubber balls 72 arranged in a staggered manner are fixedly connected to the top end of the film covering 15 and the bottom end of the buffer plate 7; during operation, the buffer plate 7 installed at the top end of the film covering 15 and the rotatability of the fifth rotating shaft 71 can buffer the external impact. At the same time, the staggered arrangement of the plurality of groups of rubber balls 72 makes contact with each other during the rotation of the buffer plate 7. The buffer plate 7 installed at the top end of the film covering 15 can block the sundries in the wind in heavy rain and strong wind weather, reducing the direct impact of the sundries on the photovoltaic panel 1, causing damage to the photovoltaic panel 1 and affecting the power generation efficiency. At the same time, the contact between the rubber balls 72 can buffer the impact, further reducing the influence of the impact force.

[0039] As Figure 7 shown, a third sliding groove 8 is opened inside each group of buffer plates 7; a second elastic rope 81 is arranged inside the third sliding groove 8; both ends of the second elastic rope 81 are attached to the side walls of a pair of fifth rotating shafts 71; a second impact ball 82 is fixedly connected to the middle of the second elastic rope 81; a plurality of groups of blocking balls 83 arranged in a staggered manner are fixedly connected to the inner side wall of the third sliding groove 8; during operation, when the buffer plate 7 is impacted by an external object, the fifth rotating shaft 71 is used for rotation to buffer. At this time, when the second elastic rope 81 is pulled, the second impact ball 82 is driven to move between the blocking balls 83, generating continuous impacts. Subsequently, the second elastic rope 81 uses its own elasticity to assist the buffer plate 7 to reset. The movement of the second elastic rope 81 driving the second impact ball 82 can make the second impact ball 82 contact and collide with the blocking balls 83, generating a vibration effect, loosening and cleaning the dust wetted by water on the top end of the film covering 15, and reducing the residue of the dust.

[0040] As Figure 7 shown, rubber plates 9 are fixedly connected to the side walls of multiple groups of the rubber balls 72; there are multiple groups of the rubber plates 9, and the rubber plates 9 corresponding to the side walls of the rubber balls 72 are arranged in an interleaved manner; during operation, when the buffer plate 7 moves under an external impact, the distances between multiple groups of the rubber balls 72 approach. At this time, multiple groups of the rubber plates 9 come into contact and squeeze each other, generating a buffering effect. By using the interleaved arrangement of multiple groups of the rubber plates 9 and cooperating with the rubber balls 72, the impact force received by the buffer plate 7 is further buffered, reducing the damage to the buffer plate 7 caused by external objects and improving the service life of the equipment.

[0041] Embodiment 2

[0042] As Figure 8 shown, compared with Embodiment 1, another implementation manner of the present invention is that water diversion plates 101 are fixedly connected to the side walls of multiple groups of the film coatings 15; the water diversion plates 101 and the side walls of the film coatings 15 are connected by springs; during operation, when water flows through the film coatings 15, the curvature of the water diversion plates 101 will give the water an upward guidance, driving the water to flow to a farther position. By using the change in the water landing position caused by the curvature of the water diversion plates 101, the water can fall more precisely into the second sliding groove 21, improving the stability during the operation of the equipment.

[0043] During operation, after the staff completes the installation of the photovoltaic panel 1, after long-term use, there are often dust and impurities on the photovoltaic panel 1, which will affect the light energy absorption effect. At this time, in the face of rainy weather, after the photovoltaic panel 1 is washed by rainwater, the rainwater will carry away some dust and discharge it through the water leakage holes 12. At this time, some of the dust adhered to the photovoltaic panel 1 is not easy to be washed away. At this time, the central processor controls the rotation of the second rotating shaft 18 in an area, driving the film covering 15 to move inside the first sliding groove 13. Under the action of the rainwater impact, the first rotating shaft 16 will rotate, so that the cleaning plate 17 sweeps the impurities adhered above the photovoltaic panel 1. Under the continuous forward and reverse rotation of the second rotating shaft 18, multiple groups of first rotating shafts 16 are driven to move back and forth above the photovoltaic panel 1. When the water flows through the film covering 15, part of the water flows into the water passing holes 23 inside and the surface of the photovoltaic panel 1 through the water guiding grooves 2. After the water flows into the water passing holes 23 inside, it will impact the scraping plate 22, driving the scraping plate 22 to move. At this time, the rotation of the first rotating shaft 16 drives the scraping plate 22 moving out of the second sliding groove 21 to contact the surface of the photovoltaic panel 1. After the water flows through the water passing holes 23 into the second sliding groove 21, the scraping plate 22 moves downward under the impact of the water flow. When it contacts the top of the photovoltaic panel 1, the scraping plate 22 will receive an upward reaction force, driving the water flow to move upward. At this time, the water flow drives the sealing plate 32 to move so that it fits on the sealing groove 33, preventing the water flow from passing through and slowing down the movement of the scraping plate 22. When the water flow squeezes the sealing plate 32, the sealing plate 32 will move above the support plate 4 and maintain its own position through the support of the support plate 4. When the scraping plate 22 contacts the surface of the photovoltaic panel 1, the impact force generated is used to move the sealing plate 32 upward, driving the contact between the limiting groove 43 opened on the side wall of the sealing plate 32 and the limiting ball 42, and briefly sealing the third rotating shaft 31. During the movement of the scraping plate 22, after the second magnet 52 breaks away from the range of the second sliding groove 21, the second magnet 52 unfolds outward under the action of the torsion spring of the fourth rotating shaft 51, cooperating with the scraping plate 22 to scrape the surface of the photovoltaic panel 1. When recycling the film covering 15 later, the scraping plate 22 completely enters the second sliding groove 21 under the external pressure. Under the repulsive force of the magnetic force between the first magnet 5 and the second magnet 52, the second magnet 52 is pressed to fit on the side wall of the scraping plate 22. During the movement of the scraping plate 22 pushed by the water, the first elastic rope 6 will be pulled, driving the second magnet 52 to unfold outward, increasing the contact area with the top surface of the photovoltaic panel 1. At the same time, under the elastic action of the first elastic rope 6, the scraping plate 22 can be driven to recover and reset, driving the first impact balls 61 existing on the first elastic rope 6 to collide with each other. The buffer plate 7 installed on the top of the film covering 15 and the rotatability of the fifth rotating shaft 71 can buffer the external impact. At the same time, the staggered arrangement of multiple groups of rubber balls 72 makes contact with each other during the rotation of the buffer plate 7. When the buffer plate 7 is impacted by an external object, the fifth rotating shaft 71 is used for rotation to buffer,At this time, when the second elastic rope 81 is pulled, it drives the second impact ball 82 to move between the blocking balls 83, generating continuous impacts. Subsequently, the second elastic rope 81 uses its own elasticity to assist the buffer plate 7 in resetting. During the process of the buffer plate 7 moving under external impact, the distances between multiple rubber balls 72 approach. At this time, multiple rubber plates 9 come into contact and squeeze each other, generating a buffering effect.
