Description

Technical Field

[0001] The present invention relates to photovoltaic cell cleaning, in particular to a photovoltaic cell cleaning device which changes the position of a spray head through a sliding mechanism. Background Art

[0002] Photovoltaic cells are devices that directly convert light energy into electrical energy through the photoelectric effect or photochemical effect. Thin-film solar cells that work with the photoelectric effect are the mainstream, while solar cells that work with the principle of photochemical effect are still in their infancy. When sunlight shines on the semiconductor pn junction, new hole-electron pairs are formed. Under the action of the pn junction electric field, holes flow from the n region to the p region, and electrons flow from the p region to the n region. When the circuit is connected, current is formed.

[0003] In order to ensure the maximum absorption of light energy, the existing photovoltaic cells are generally set to form an inclined surface at a certain angle with the ground. Since the photovoltaic cells need to be installed outdoors, they will be in contact with the outside air. Over a long period of time, dust in the outside air is easy to adhere to its surface, resulting in the surface of the photovoltaic cells being covered and the efficiency of absorbing light energy being greatly reduced. At this time, it is necessary to regularly clean the surface of the photovoltaic cells. The existing cleaning methods are generally divided into manual cleaning and machine cleaning. Manual cleaning uses a brush head support rod to scrape and wash the surface of the photovoltaic cell through manual control. This cleaning method has a low cleaning effect, and during the cleaning process, the brush head cannot remain parallel to the surface of the photovoltaic cell. During the cleaning process, the gravity generated by the entire brush head and the thrust applied by humans are jointly applied to the surface of the photovoltaic cell, which can easily scratch the surface of the photovoltaic cell. When the machine is cleaning, the brush is driven by a mobile trolley to scrape and wash along the surface of the photovoltaic cell. This cleaning method can only be adapted to large photovoltaic cell sites with large gaps between photovoltaic cells. For some small photovoltaic cell sites with dense density, it is difficult for the mobile trolley to reach into the interior of the photovoltaic cell site to clean photovoltaic cells in different areas, which has high limitations. Therefore, there is an urgent need for a photovoltaic cell cleaning device that changes the position of the spray head through a sliding mechanism. Summary of the invention

[0006] As a further improvement of the technical solution, bottom grooves are provided on both sides of the top of the bottom plate, and sliders are provided at the bottom ends of the adjustment component and the drive component, and the sliders are slidably connected to the bottom grooves.

[0007] As a further improvement of the technical solution, a limit plate is provided at the inner end position of the slide groove, and the cross-sectional dimension of the limit plate is consistent with the cross-sectional dimension of the inner side of the slide groove.

[0008] As a further improvement of the technical solution, a limiting block is slidably connected to the inner side of the slide groove near the end position, and a buffer spring is connected between the limiting block and the limiting plate.

[0009] As a further improvement of the technical solution, a plurality of scale grooves are provided on one side of the connecting rod close to the connecting plate, and the scale grooves are equidistantly distributed on the side of the connecting rod.

[0010] As a further improvement of the technical solution, balls are provided on both sides of the sliding head, and the balls are in rolling connection with the inner end of the limiting groove.

[0011] As a further improvement of the technical solution, a positioning assembly is connected between the bottom ends of the two inclined rods, and the positioning assembly includes a plate, a plurality of arc grooves are opened on the top of the plate, the plate is kept parallel to the inclined rod, and pillars are arranged at both ends of the top of the plate, and a connecting head is connected to the top of the pillar, and the connecting head is arranged at the bottom end of the inclined rod.

[0012] As a further improvement of the technical solution, the edges of the boards are provided with guard bars, and the guard bars protrude from the top of the boards.

[0013] As a further improvement of the technical solution, a plurality of buffer columns are arranged at the top end of the enclosure rod, each of the buffer columns is plugged into and fitted with the top end of the enclosure rod, and a return spring is arranged at the bottom end of the buffer column.

[0014] As a further improvement of the technical solution, an insertion rod is provided at the top of the pillar, and the insertion rod is plugged into and matched with the bottom end of the connecting head. A limiting spring is provided on the inner side of the bottom end of the connecting head, and the bottom end of the limiting spring is connected to the top of the insertion rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the photovoltaic cell cleaning device that changes the position of the spray head by a sliding mechanism, the angles of the two inclined rods are adjusted by a set driving component to adapt to the cleaning of photovoltaic cells with different offset angles, thereby improving the flexibility of the entire device. The driving component pushes the two inclined rods to perform circular motion with the top of the support rod as the axis until the bottom surface of the inclined rod is parallel to the surface of the photovoltaic cell. At this time, the height of each nozzle is consistent with the surface of the photovoltaic cell, so that the cleaning liquid sprayed from the inner end of the nozzle can be evenly sprayed on the surface of the photovoltaic cell, thereby improving the cleaning effect of the surface of the photovoltaic cell.

[0017] 2. In the photovoltaic cell cleaning device that changes the position of the spray head by a sliding mechanism, the inner end of the slide groove is sealed by a limit plate. When the side block is about to slide out of the end of the slide groove, the end of the side block is blocked by the limit plate and cannot move further, thereby preventing the side block from detaching from the inner end of the slide groove.

[0018] 3. In the photovoltaic cell cleaning device that changes the position of the injection head by a sliding mechanism, the position of the side block is limited by a limit block. When the side block slides to the end of the slide groove, the side surface of the side block will come into contact with the side surface of the limit block in advance, pushing the limit block to slide along the inner end of the slide groove. The limit block drives the buffer spring to contract, and the reverse force generated by the contraction of the buffer spring offsets the pressure generated during the sliding process of the side block, thereby playing a certain buffering role on the side block, further reducing the damage to the side block during the sliding process, and increasing the service life of the side block.

[0019] 4. In the photovoltaic cell cleaning device that changes the position of the spray head by a sliding mechanism, the position of the inclined rod is automatically corrected by the provided surrounding rod. When the inclined rod makes a circular motion along the top of the support rod, it drives the sticking plate to move along the photovoltaic cell. When the top of the sticking plate fits with the bottom surface of the photovoltaic cell, the movement of the inclined rod is stopped, and the sticking plate and the inclined rod remain parallel. The sticking plate fits with the bottom surface of the photovoltaic cell, which means that the inclined rod and the photovoltaic cell remain parallel at this time, helping the cleaning personnel to correct the position of the inclined rod more accurately.

[0037] See also Figure 1-Figure 11 As shown, a photovoltaic cell cleaning device for changing the position of a spray head by a sliding mechanism is provided, including a support frame 10, the support frame 10 includes a bottom plate 110, a plurality of rollers 111 are arranged at the bottom end of the bottom plate 110, a pair of adjustment components 120 are arranged on one side of the top end of the bottom plate 110, the adjustment component 120 includes a support rod 121, an inclined rod 122 is hinged at the top end of the support rod 121, a limiting groove 1221 is arranged at the bottom end of the inclined rod 122, a sliding groove 1222 is arranged on the side of the inclined rod 122, and a driving component 130 is arranged on the other side of the top end of the bottom plate 110, and the driving component 130 includes a pair of connecting rods 131, and the connecting rods An inner plate 132 is slidably connected to the inner side of 131, a connecting plate 133 is connected between the bottom ends of the two inner plates 132, a hydraulic rod 134 is provided at the bottom end of the connecting plate 133, a sliding head 135 is rotatably connected to the top end of the inner plate 132, the sliding head 135 is slidably connected to the limiting groove 1221, a cleaning assembly 20 is provided between the two inclined rods 122, the cleaning assembly 20 includes a water tank 210, side blocks 211 are provided on both sides of the water tank 210, the side blocks 211 are slidably connected to the slide groove 1222, a pair of telescopic rods 220 are provided at the end of the water tank 210, and a plurality of nozzles 212 are provided at the bottom of the water tank 210.

[0038] During specific use, the calibration process is: first, move the entire device to the bottom end of the photovoltaic cell that needs to be cleaned, and the hydraulic rod 134 drives the connecting plate 133 to move up and down in the vertical direction. The connecting plate 133 drives the two inner plates 132 to move up and down along the inner end of the connecting rod 131, and the inner plate 132 drives the sliding head 135 to move up and down. During the up and down movement of the sliding head 135, it keeps rotating with the top of the inner plate 132. At the same time, the sliding head 135 slides along the inner end of the limiting groove 1221, and the two sliding heads 135 push the two inclined rods 122 to make circular motion with the top of the support rod 121 as the axis. At this time, observe the position of the inclined rod 122 and the photovoltaic cell. When the bottom surface of the inclined rod 122 remains parallel to the surface of the photovoltaic cell, close the hydraulic rod 134, and the calibration work is completed.

[0039] Cleaning process: After the calibration work is completed, the bottom surface of the inclined rod 122 remains parallel to the surface of the photovoltaic cell. At this time, the bottom end of the water tank 210 remains parallel to the surface of the photovoltaic cell. The cleaning liquid contained in the inner end of the water tank 210 is sprayed along the side blocks 211 to the surface of the photovoltaic cell to clean the dust adhering to the surface of the photovoltaic cell. At the same time, the two telescopic rods 220 drive the water tank 210 to slide parallel to the surface of the photovoltaic cell, so that the cleaning liquid sprayed by the side blocks 211 can cover the surface of the photovoltaic cell, and different positions on the surface of the photovoltaic cell are fully cleaned.

[0040] The present invention adjusts the angles of the two inclined rods 122 by setting a driving component 130 to adapt to the cleaning of photovoltaic cells with different offset angles, thereby improving the flexibility of the entire device. The driving component 130 pushes the two inclined rods 122 to perform circular motion with the top of the support rod 121 as the axis until the bottom surface of the inclined rod 122 is parallel to the surface of the photovoltaic cell. At this time, the height of each nozzle 212 is consistent with the surface of the photovoltaic cell, so that the cleaning liquid sprayed from the inner end of the nozzle 212 can be evenly sprayed on the surface of the photovoltaic cell, thereby improving the cleaning effect of the surface of the photovoltaic cell.

[0041] In addition, bottom grooves 112 are provided on both sides of the top of the bottom plate 110, and sliders are provided at the bottom ends of the adjustment assembly 120 and the driving assembly 130, and the sliders are slidably connected to the bottom grooves 112. In specific use, since photovoltaic cells are generally arranged in a row, and the angles formed by the photovoltaic cells in the same row and the ground are consistent, after the correction work of the entire device is completed, it is only necessary to slide the support rod 121 and the driving assembly 130 horizontally along the bottom groove 112 to drive the water tank 210 to slide horizontally to clean each photovoltaic cell in the same row, without re-adjusting the angle of the entire device, thereby improving the cleaning efficiency of the entire device.

[0042] Since the ends of the slide slots 1222 are in an exposed state, the two side blocks 211 respectively keep sliding with the inner ends of the two slide slots 1222 during the movement of the water tank 210 along the two inclined rods 122. When the side blocks 211 slide out of the ends of the slide slots 1222, the water tank 210 loses the limitation of the side blocks 211, and the entire water tank 210 is supported only by the two telescopic rods 220. The pressure on the telescopic rods 220 is too great, and it is easy to be over-stressed and deflected, resulting in the water tank 210 being unable to reset. Furthermore, a limit plate 123 is provided at the inner end of the slide slot 1222, and the cross-sectional size of the limit plate 123 is kept consistent with the inner cross-sectional size of the slide slot 1222. The inner end of the slide slot 1222 is sealed by the set limit plate 123, and when the side block 211 is about to slide out of the end of the slide slot 1222, the end of the side block 211 is blocked by the limit plate 123 and cannot continue to move, thereby preventing the side block 211 from detaching from the inner end of the slide slot 1222.

[0043] Furthermore, the inner side of the slide groove 1222 is slidably connected to the limit block 124 near the end position, and a buffer spring 125 is connected between the limit block 124 and the limit plate 123. In specific use, during the contact process between the side block 211 and the limit plate 123, a collision will occur between the two, and the pressure generated can easily cause wear to the end of the side block 211, affecting the service life of the side block 211. At this time, the position of the side block 211 is limited by the set limit block 124. When the side block 211 slides to the end of the slide groove 1222, the side of the side block 211 will contact the side of the limit block 124 in advance, pushing the limit block 124 to slide along the inner end of the slide groove 1222, and the limit block 124 drives the buffer spring 125 to contract. The reverse force generated by the contraction of the buffer spring 125 offsets the pressure generated during the sliding process of the side block 211, thereby playing a certain buffering role on the side block 211, further reducing the damage to the side block 211 during the sliding process, and improving the service life of the side block 211.

[0044] Specifically, a plurality of scale grooves 1311 are provided on one side of the connecting rod 131 close to the connecting plate 133, and each scale groove 1311 is equidistantly distributed on the side of the connecting rod 131. When in use, the angle adjustment of the water tank 210 is proportional to the sliding height of the connecting plate 133. Different heights of the connecting plate 133 correspond to different angles of the water tank 210. Since photovoltaic cells in different areas are affected by different light intensities, the angles formed between the photovoltaic cells and the ground are also different. When cleaning the photovoltaic cells in these different areas, the operator needs to make multiple angle adjustments. When cleaning the photovoltaic cells in the same area again, since the previous angle is difficult to measure, a secondary position correction is required, which greatly reduces the cleaning efficiency. At this time, the scale grooves 1311 are provided to provide a reference point for the cleaning personnel. When cleaning the photovoltaic cells in the same area, the displacement height of the connecting plate 133 is recorded. During the secondary cleaning, the connecting plate 133 is directly moved to the recorded height without re-position correction, thereby improving the cleaning efficiency.

[0045] As the sliding head 135 slides along the inner end of the limiting groove 1221, friction resistance will be generated at the contact position between the two, and the direction of this friction resistance is opposite to the sliding direction of the sliding head 135, which hinders the normal sliding of the sliding head 135. In addition, balls 1351 are provided on both sides of the sliding head 135, and the balls 1351 maintain a rolling connection with the inner end of the limiting groove 1221. The contact area between the sliding head 135 and the limiting groove 1221 is reduced by the provided balls 1351, and the contact area is proportional to the friction resistance. Reducing the contact area between the sliding head 135 and the limiting groove 1221 means reducing the friction resistance, thereby improving the sliding efficiency of the sliding head 135.

[0046] Furthermore, a positioning assembly 30 is connected between the bottom ends of the two inclined rods 122. The positioning assembly 30 includes a plate 310. A plurality of arc grooves 311 are provided at the top of the plate 310. The plate 310 remains parallel to the inclined rod 122. Support pillars 320 are provided at both ends of the top of the plate 310. A connecting head 330 is connected to the top of the supporting head 320. The connecting head 330 is provided at the bottom end of the inclined rod 122. During specific use, in the process of adjusting the water tank 210 to be parallel to the surface of the photovoltaic cell, it is necessary for the cleaning personnel to observe in time with the naked eye, and due to the influence of light, the naked eye cannot observe accurately. At this time, the position of the inclined rod 122 is automatically corrected by the set fence 340. When the inclined rod 122 makes a circular motion along the top of the support rod 121, it drives the plate 310 to move along the photovoltaic cell. When the top of the plate 310 is in contact with the bottom surface of the photovoltaic cell, the movement of the inclined rod 122 is stopped, and the plate 310 is kept parallel to the inclined rod 122. The plate 310 is in contact with the bottom surface of the photovoltaic cell, which indicates that the inclined rod 122 is parallel to the photovoltaic cell at this time, which helps the cleaning personnel to correct the position of the inclined rod 122 more accurately.

[0047] When the cleaning liquid flows along the surface of the photovoltaic cell, due to the influence of gravity, the cleaning liquid will flow downward along the surface of the photovoltaic cell. Furthermore, a fence 340 is provided at the edge of the plate 310, and the fence 340 protrudes from the top of the plate 310. The fence 340 is provided to form a ring-shaped fence on the top of the plate 310, so that the cleaning liquid flowing downward along the surface of the photovoltaic cell is collected and prevented from flowing downward and splashing onto the surface of the support frame 10. Over time, the cleaning liquid with dust will adhere to various positions of the support frame 10, requiring cleaning personnel to perform secondary cleaning, increasing the workload of cleaning personnel.

[0048] In addition, a plurality of buffer columns 341 are disposed at the top of the surrounding rod 340 , and each buffer column 341 is plugged into and matched with the top of the surrounding rod 340 , and a return spring is disposed at the bottom of the buffer column 341 . When the top of the fence 340 contacts the bottom of the photovoltaic cell, the top of the fence 340 will collide with the bottom of the photovoltaic cell. The thrust generated by the collision can easily cause the photovoltaic cell to move, resulting in the need to perform a secondary correction on the corrected water tank 210, affecting normal cleaning work. At the same time, the long-term collision of the plate 310 with the bottom of the photovoltaic cell can easily cause damage to the photovoltaic cell, affecting the service life of the photovoltaic cell. At this time, the photovoltaic cell is protected by the provided buffer column 341. When the top of the fence 340 is about to contact the bottom of the photovoltaic cell, the top of each buffer column 341 contacts the bottom of the photovoltaic cell in advance. The pressure generated during the movement of the fence 340 will act on the top of each buffer column 341, causing each buffer column 341 to extend into the inner end of the fence 340 and squeeze each reset spring. The reverse force generated by the contraction of the reset spring offsets the pressure generated during the movement of the fence 340, thereby playing a certain buffering role on the bottom of the photovoltaic cell, avoiding excessive pressure generated during the movement of the fence 340, thereby reducing the possibility of displacement of the photovoltaic cell.

[0049] In addition, a plug rod 321 is provided at the top of the pillar 320, and the plug rod 321 is plugged with the bottom end of the connector 330. A limit spring 331 is provided inside the bottom end of the connector 330, and the bottom end of the limit spring 331 is connected to the top end of the plug rod 321. When in use, the limit spring 331 is in a balanced state when the surrounding rod 340 is not interfered by external forces. When the cleaning personnel pull the plate 310 to move to the bottom end of the photovoltaic cell, the two limit springs 331 are in a stretched state. When the plate 310 is parallel to the bottom end of the photovoltaic cell, the plate 310 is released, and the two limit springs 331 return to their original state, driving the plate 310 to fit to the bottom end of the photovoltaic cell, further improving the position correction efficiency of the plate 310.
