Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and in particular to a photovoltaic module surface cleaning device and a use method thereof. Background Art

[0002] In the application of solar energy, the power generation of photovoltaic modules depends on many factors. In addition to the influence of electrical components such as inverters and transformers, in snowy weather in winter, a large amount of snow will remain on the surface of photovoltaic modules, which will not only cause damage to the photovoltaic panels, but also block the surface of the solar photovoltaic panels, affecting the efficiency of solar power generation.

[0003] The existing snow removal method uses a snow shovel to directly shovel snow on the surface of the photovoltaic module. However, during the snow shoveling process, the snow shovel directly contacts the photovoltaic module, which can easily cause damage to it. At the same time, some snow accumulates on the surface of the photovoltaic module for a long time and is prone to ice. It is not suitable to clean the ice at this time. In addition, when shoveling snow, a small amount of snow is likely to remain on the surface, which can easily lead to incomplete cleaning. For this reason, we propose a photovoltaic module surface cleaning device and a method for use. Summary of the Invention

[0018] S4: After dealing with the accumulated snow, the fan drives the air flow to blow the surface of the surrounding photovoltaic module body to accelerate the cleaning efficiency of dust and snow water.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are as follows.

[0020] 1. The present invention provides a surface cleaning device and a using method for a photovoltaic module. It drives the sliding frame to slide through an electric slide rail, so that the first gear on the surface of the support rod contacts the first rack on the slide rail. At this time, the moving first gear drives the push rod on the surface to rotate through the support rod, and the push rod drives the rotating cylinder to rotate. At this time, the snow shovel at the bottom rotates. At the same time, the sliding frame drives the cleaning frame to move through the movement of the rotating cylinder, so that the snow shovel on the surface of the cleaning frame can rotate when moving. The snow shovel is inclined, which can improve the snow removal efficiency. At the same time, there is a certain distance between the snow shovel and the photovoltaic module, and the snow shovel does not directly contact the photovoltaic module body, which can reduce the extra burden caused by friction and resistance, make the snow shoveling process easier, thus improving the work efficiency, and can avoid damage to its surface when the snow shovel contacts the photovoltaic module.

[0021] 2. The present invention provides a surface cleaning device and a using method for a photovoltaic module. When cleaning, it starts the fan, which can suck the lifted accumulated snow into the inside of the rotating cylinder. At the same time, a convex lens is arranged on the surface of the rotating cylinder, which can concentrate the external light at this time, and can heat the heat conducting rod inside. The convex lens rotates with the rotating cylinder, which can absorb the surrounding light with higher efficiency and concentrate and irradiate it on the heat conducting rod to accelerate its heating speed. At this time, the accumulated snow can be heated and melted, and the melted snow water enters the connecting pipe and then enters the water collecting box. When rotating, the heated snow water is thrown out by centrifugal force and contacts the remaining light snow on the top of the photovoltaic module body, which can melt it, and can remove snow and dust from some dead corners that are not easy to clean by spraying water.

[0022] 3. The present invention provides a surface cleaning device and a usage method for a photovoltaic module. When it comes into contact with the first guide groove through the guide rod, when the fourth gear on the positioning post contacts the second one, the fourth gear drives the positioning post to rotate half a turn. The rotating frame drives the second gear to rotate half a turn. At the same time, the rotating frame drives the second gear to move upward and contact the second toothed ring. The second toothed ring can drive the connecting cylinder to rotate. The connecting cylinder drives the third gear on the surface of the cleaning frame to rotate half a turn through the first toothed ring, and drives the flexible plate on the surface of the cleaning frame to rotate half a turn. At this time, the flexible plate is perpendicular to the photovoltaic module and contacts the surface of the photovoltaic module. Cooperating with the snow water sprayed out from the water collecting box, it can clean the melted snow water and less accumulated snow on its surface, effectively improving the snow removal efficiency, and can timely clean the snow water on the surface to avoid the situation of snow water freezing after a long time, thus enhancing the working effect of the device.

[0023] 4. The present invention provides a surface cleaning device and a usage method for a photovoltaic module. When the flexible plate driven by the rotating cylinder cleans the snow water and dust on the surface of the photovoltaic module, the fan drives the air flow to enter the interior of the water collecting box through the connecting pipe, and through the heating of the heat conducting rod, the air inside the rotating cylinder can be heated. At this time, it can blow air on the surface of the surrounding photovoltaic module body, which can effectively accelerate the cleaning efficiency of the dust and snow water, and make the surface of the photovoltaic module body dry quickly.

When the rotating cylinder 8 is moving, the snow shovels 11 at the bottom can clean the snow on the top of the photovoltaic module.

[0039] Embodiment 2, as Figures 1-10As shown in the figure, a connecting cylinder 17 is rotatably connected to the surface of the cleaning rod 9 through a bearing. A first toothed ring 18 is fixedly connected to the lower surface of the connecting cylinder 17. A third gear 19 is fixedly connected to the outer surface of a plurality of cleaning frames 10. The first toothed ring 18 is meshed with the third gear 19. A second toothed ring 20 is fixedly connected to the upper surface of the connecting cylinder 17.

The clamping block 29 is clamped with one of the claw slots.

[0040] The overall effect achieved by the entire Embodiment 2 is that when the sliding frame 5 enters the top support frame 2, at this time, the guiding rod 27 comes into contact with the first guiding groove and moves upward along the first guiding groove. At this time, the positioning column 22 can be lifted upward, and at this time, the clamping block 29 disengages from one of the claw slots. When the fourth gear 28 at the top driven by the positioning column 22 comes into contact with the second one, at this time, the fourth gear 28 drives the positioning column 22 to rotate half a circle. The positioning column 22 drives the rotating frame 23 to rotate half a circle. The rotating frame 23 drives the second gear 24 to rotate half a circle. At the same time, the positioning column 22 drives the second gear 24 to move upward through the rotating frame 23 and comes into contact with the second toothed ring 20.

After the positioning column 22 rotates half a circle, the guiding rod 27 rotates into the second guiding groove and drops to its bottom along the second guiding groove. At this time, the clamping block 29 is clamped into the inside of another claw slot. At this time, the soft plate 21 comes into contact with the surface of the photovoltaic module, and the melted snow water and less accumulated snow on its surface can be cleaned.

[0041] Embodiment 3, as Figures 1-10As shown in the figure, a convex lens 30 and a fan 31 are fixedly installed on the outer surface of the rotating cylinder 8. A heat conduction rod 32 is fixedly connected to the inner surface of the rotating cylinder 8. A connecting pipe 33 is communicated with the lower surface of the rotating cylinder 8. The tail end of the connecting pipe 33 is communicated with a water collecting box 34. A plurality of water outlet holes are formed on the surface of the water collecting box 34. Ventilation holes are formed on the outer surface of the rotating cylinder 8. A plurality of sliding grooves are formed on the surface of the support frame 2.

[0042] The effect achieved by the entire Embodiment 3 is that when cleaning, the fan 31 installed on the surface of the rotating cylinder 8 can suck the lifted snow into the interior of the rotating cylinder 8. At the same time, a convex lens 30 is arranged on the surface of the rotating cylinder 8, and at this time, the external light can be concentrated, and the internal heat conduction rod 32 can be heated. At this time, the snow can be heated and melted. The melted snow water enters the connecting pipe 33 and then enters the water collecting box 34. When rotating, the heated snow water is thrown out and contacts the thin snow on the top of the photovoltaic module body 3, and it can be melted.

[0043] As Figures 1-10 shown, a method for cleaning the surface of a photovoltaic module includes the following steps:

[0044] S1: When dealing with snow, the electric slide rail 4 drives the sliding frame 5 to slide, and the push rod 16 drives the rotating cylinder 8 to rotate. At this time, the snow shovel 11 at the bottom of the rotating cylinder 8 rotates while moving, and at this time, the snow on the surface of the photovoltaic module body 3 is removed.

[0045] S2: When dealing with thin snow, the fan 31 is started, and the lifted snow can be sucked into the interior of the rotating cylinder 8. The convex lens 30 concentrates the external light, and the snow is heated and melted through the heat conduction rod 32. The melted snow water is thrown out by centrifugal force and contacts the remaining thin snow on the top of the photovoltaic module body 3, melting it.

[0046] S3: When dealing with thin snow, the flexible plate 21 is rotated so that the flexible plate 21 is perpendicular to the photovoltaic module body 3 and contacts the surface of the photovoltaic module. Cooperating with the snow water sprayed from the water collecting box 34, the melted snow water and less snow on the surface of the photovoltaic module body 3 are cleaned.

[0047] S4: After dealing with the snow, the fan 31 drives the air flow to blow the surface of the surrounding photovoltaic module body 3 to accelerate the cleaning efficiency of dust and snow water.

[0048] Working principle: When the sliding frame 5 is not in use, it is stored in the bottom support frame 2. When snow removal is carried out, the electric slide rail 4 is started. The electric slide rail 4 drives the sliding frame 5 to slide. The sliding frame 5 drives the mounting frame 6 at the top to move. The mounting frame 6 drives the rotating rod 7 to move. The rotating rod 7 drives the rotating cylinder 8 at the bottom to move. The rotating cylinder 8 drives the cleaning rod 9 to move. The cleaning rod 9 drives the cleaning frame 10 to move. The cleaning frame 10 drives the snow plow 11 on its surface to move. At the same time, the sliding frame 5 drives the fixing plate 13 at the bottom to move. The fixing plate 13 drives the support rod 14 to move. The support rod 14 drives the first gear 15 on its surface to move. The first gear 15 contacts the first rack 12 on the slide rail. When moving, the first gear 15 drives the support rod 14 to rotate. The support rod 14 drives the push rod 16 on its surface to rotate. The push rod 16 contacts the limiting groove on the surface of the rotating cylinder 8 and drives the rotating cylinder 8 to rotate. At this time, the cleaning rod 9 at the bottom can rotate. The cleaning rod 9 drives the snow plow 11 to rotate through the cleaning frame 10. At this time, there is a certain distance between the snow plow 11 and the photovoltaic module. When the rotating cylinder 8 is moving, the snow plow 11 at the bottom can clean the snow on the top of the photovoltaic module. When most of the snow on the surface has been cleaned, there is a small amount of snow remaining on the top of the photovoltaic module body 3 that the snow plow 11 cannot reach. When cleaning, the fan 31 installed on the surface of the rotating cylinder 8 can suck the lifted snow into the inside of the rotating cylinder 8. At the same time, a convex lens 30 is provided on the surface of the rotating cylinder 8. At this time, the external light can be concentrated, and the heat conducting rod 32 inside can be heated. At this time, the snow can be heated and melted. The melted snow water enters the connecting pipe 33 and enters the water collecting box 34. When rotating, the heated snow water is thrown out and contacts the thin snow on the top of the photovoltaic module body 3, which can melt it. At this time, the sliding frame 5 continues to rise. When it enters the inside of the top support frame 2, the guide rod 27 contacts the first guide groove and moves upward along the first guide groove. At this time, the positioning column 22 can be lifted upward. At this time, the clamping block 29 disengages from one of the card slots. When the positioning column 22 drives the fourth gear 28 at the top to contact the second one, the fourth gear 28 drives the positioning column 22 to rotate half a circle. The positioning column 22 drives the rotating frame 23 to rotate half a circle. The rotating frame 23 drives the second gear 24 to rotate half a circle. At the same time, the positioning column 22 drives the second gear 24 to move upward through the rotating frame 23 and contacts the second toothed ring 20. When the second gear 24 rotates, it can drive the second toothed ring 20 to rotate half a circle. The second toothed ring 20 drives the connecting cylinder 17 to rotate. The connecting cylinder 17 drives the first toothed ring 18 at the bottom to rotate. The first toothed ring 18 drives the third gear 19 on the surface of the cleaning frame 10 to rotate half a circle. The third gear 19 drives the cleaning frame 10 to rotate half a circle. The cleaning frame 10 drives the flexible plate 21 to rotate half a circle. At this time, the flexible plate 21 is perpendicular to the photovoltaic module. At this time, the sliding frame 5 is moved downward. After the positioning column 22 rotates half a circle, the guide rod 27 rotates into the second guide groove and drops to its bottom along the second guide groove.At this time, the clamping block 29 is clamped into the interior of another card slot. At this time, the flexible board 21 is in contact with the surface of the photovoltaic module, and can clean the melted snow water and less accumulated snow on its surface. At the same time, the fan 31 drives the air flow to enter the interior of the water collecting box 34 through the connecting pipe 33, and through the heating of the heat conducting rod 32, the air inside the rotating cylinder 8 can be heated. At this time, the air can be blown onto the surface of the surrounding photovoltaic module body 3, which can effectively improve the cleaning efficiency of dust and snow water, and enable the surface of the photovoltaic module body 3 to dry quickly. When the sliding frame 5 moves to the bottom guide frame 25, it can drive the positioning column 22 to rotate in the reverse direction, so that the flexible board 21 and the snow shovel 11 are flipped, and the next snow removal can be continued.,

Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
