Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, specifically an automatic cleaning machine for photovoltaic panels. Background Technology

[0002] Photovoltaic panels are installed outdoors, and the surface of the photovoltaic panels is affected by the environment, resulting in the accumulation of dust, powder, fallen leaves, bird droppings, and frost and snow caused by low ambient temperature. This reduces the utilization rate of photovoltaic power generation and causes some energy loss. Therefore, in order to improve the photoelectric conversion effect of photovoltaic panels, corresponding cleaning machines are usually used to clean the surface of photovoltaic panels.

[0003] For example, a photovoltaic panel cleaning device with announcement number CN219204450U includes installation mechanisms movably installed at both ends of a photovoltaic panel. The installation mechanisms are provided in two sets, with a spray assembly, a cleaning assembly, and a wiping assembly slidably arranged between the two sets of installation mechanisms. Each installation mechanism includes a mounting frame and a clamping frame, with the clamping frame slidably disposed within the mounting frame. A return spring abuts against the mounting frame and the clamping frame. The above-mentioned prior art has the following technical problems:

[0004] Existing cleaning equipment uses brush rollers and spray components to remove impurities from the surface of photovoltaic panels. However, the spray nozzles have a fixed spray range during the water cleaning process, which means that water can only be sprayed onto a fixed area, thus reducing the cleaning effect on the photovoltaic panels.

[0005] Therefore, we propose an automatic cleaning machine for photovoltaic panels to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an automatic cleaning machine for photovoltaic panels, in order to solve the problem mentioned in the background art that existing cleaning equipment on the market uses brush rollers and spray components to remove impurities from the surface of photovoltaic panels. However, during the water spraying process, the spraying range of the spray head is fixed, and water can only be sprayed towards a fixed area, which reduces the cleaning effect on photovoltaic panels in actual cleaning.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic cleaning machine for photovoltaic panels, comprising two positioning frames, each with a support block installed on its inner side, and a transmission screw installed through the middle of one of the support blocks. The end of the transmission screw is fixed to the output end of a servo motor. A mounting plate is fixed between the two support blocks, and a cleaning roller is installed in the middle of the mounting plate. A connecting gear is fixed on the central shaft of the cleaning roller, and a linkage rack fixed on the positioning frame is provided below the connecting gear. A diverter plate is fixed at the upper end of the mounting plate and is connected to an external water supply device. A nozzle is connected to the lower end of the diverter plate via a hose and is fixed to a horizontal plate. The rod at the end of the horizontal plate is connected to the mounting plate via an auxiliary spring, and a power module is provided at the end of the horizontal plate away from the auxiliary spring. The power module is used to control the reciprocating movement of the horizontal plate.

[0008] Preferably, the transmission screw and the support block are threadedly connected, and the outer wall of the support block and the inner wall of the positioning frame are in contact with each other, allowing the support block to slide inside the positioning frame.

[0009] By adopting the above technical solution, the rotation of the transmission screw enables the threaded support block to move inside the positioning frame.

[0010] Preferably, the central shaft of the cleaning roller passes through one of the support blocks, and the connecting gear on the cleaning roller shaft is meshed with the linkage rack, and the cleaning roller can rotate on the support block.

[0011] By adopting the above technical solution, when the mounting plate moves and drives the cleaning roller to move synchronously, the movement of the cleaning roller enables the connecting gear and the linkage rack to mesh and transmit power.

[0012] Preferably, multiple nozzles are evenly distributed at the lower end of the flow divider plate, and each nozzle is connected to the flow divider plate via a hose, and the horizontal plate fixed on the nozzle can slide on the mounting plate.

[0013] By adopting the above technical solution, the movement of the horizontal plate on the mounting plate can drive the nozzle to move synchronously, thereby increasing the spraying range of the water source.

[0014] Preferably, the power module includes a movable wheel, which is fixed on the central rotating shaft of the cleaning roller. A first magnetic block is fixed to the end of the blade in the circumferential direction of the movable wheel, and a second magnetic block is provided on the side of the first magnetic block. The second magnetic block is fixed on a limiting rod, and the limiting rod is fixed on a horizontal plate.

[0015] By adopting the above technical solution, the rotation of the cleaning roller can drive the movable wheel to rotate synchronously, and the rotation of the movable wheel can change the distance between the first magnetic block and the second magnetic block at the end of the limiting rod.

[0016] Preferably, multiple first magnetic blocks are evenly distributed around the circumference of the movable wheel, and the magnetic properties of the first magnetic blocks and the second magnetic blocks are the same.

[0017] By adopting the above technical solution, when the first magnetic block and the second magnetic block approach each other, the limiting rod can be moved by using repulsive magnetic force.

[0018] Preferably, the power module consists of a pressure block and a pressure receiving frame, with the pressure block fixed inside the positioning frame, and the pressure receiving frame provided on the side of the pressure block, and the pressure receiving frame fixed at the end of the horizontal plate. The end of the pressure receiving frame near the pressure block and the pressure block are both set as arc-shaped structures.

[0019] By adopting the above technical solution, when the pressure frame moves with the mounting plate, the pressure frame and the cross plate can move by contacting and separating from the pressure block.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the automatic cleaning machine for photovoltaic panels, through the setting of brush plates and nozzles, sprays water to clean the photovoltaic panels, and at the same time, through the movement of the nozzles during the cleaning process, the spray range of the water source is increased, preventing areas from being missed by the spray.

[0021] 1. Equipped with a mounting plate, the rotation of the transmission screw enables the threaded support block to drive the cleaning roller to move synchronously. The movement of the cleaning roller can clean the surface of the photovoltaic panel. At the same time, the diverter plate and nozzles can spray water outwards to rinse the photovoltaic panel.

[0022] 2. Equipped with movable wheels, the cleaning roller moves along with a connecting gear and a linkage rack, causing the cleaning roller to drive the movable wheels to rotate. The rotation of the movable wheels changes the distance between the first and second magnetic blocks, which in turn causes the limit rod to move the horizontal plate back and forth. This back and forth movement of the horizontal plate, in turn, drives the nozzle to move synchronously, thereby increasing the overall spraying range of the water source and improving the rinsing effect.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] Please see Figures 1-6Existing cleaning equipment uses brush rollers and spray components to remove impurities from the surface of photovoltaic panels. However, the spray nozzles have a fixed spray range during the water cleaning process, meaning they can only spray water onto a fixed area. This reduces the cleaning effect on the photovoltaic panels. To address this problem, this embodiment discloses the following technical details: the end of the transmission screw 3 is fixed to the output end of the servo motor 4; a mounting plate 5 is fixed between the two support blocks 2; a cleaning roller 6 is mounted in the middle of the mounting plate 5; a connecting gear 7 is fixed on the central shaft of the cleaning roller 6; a linkage rack 8 is fixed to the positioning frame 1 below the connecting gear 7; and a diverter plate 9 is fixed to the upper end of the mounting plate 5. Furthermore, the diversion plate 9 is connected to the external water supply equipment. The lower end of the diversion plate 9 is connected to the nozzle 10 via a hose, and the nozzle 10 is fixed on the horizontal plate 11. The rod at the end of the horizontal plate 11 is connected to the mounting plate 5 via an auxiliary spring 12. The transmission screw 3 and the support block 2 are threadedly connected, and the outer wall of the support block 2 and the inner wall of the positioning frame 1 are in contact with each other. The support block 2 can slide inside the positioning frame 1. The central shaft of the cleaning roller 6 passes through one of the support blocks 2, and the connecting gear 7 on the shaft of the cleaning roller 6 is meshed with the linkage rack 8. The cleaning roller 6 can rotate on the support block 2. Multiple nozzles 10 are evenly distributed at the lower end of the diversion plate 9, and each nozzle 10 is connected to the diversion plate 9 via a hose. The horizontal plate 11 fixed on the nozzle 10 can slide on the mounting plate 5.

[0033] When cleaning the photovoltaic panels is required, the support block 2 can be installed on the robotic arm or directly on the photovoltaic frame. After installation, the support block 2 ensures that the cleaning roller 6 contacts the surface of the photovoltaic panel, and the diversion plate 9 is connected to the external water supply equipment. At this time, the servo motor 4 is turned on to rotate the transmission screw 3. The rotation of the transmission screw 3 causes the threaded support block 2 to move. The movement of the support block 2 causes the mounting plate 5 to move synchronously. After the mounting plate 5 moves, the cleaning roller 6 moves. During the movement of the cleaning roller 6, the meshing action between the connecting gear 7 and the linkage rack 8 causes the cleaning roller 6 to rotate on the mounting plate 5. The rotation of the cleaning roller 6 can clean the surface of the photovoltaic panel. At the same time, water can be delivered to the inside of the diversion plate 9 using the external water supply equipment. After the water enters the inside of the diversion plate 9, the water is sprayed outwards onto the surface of the photovoltaic panel through the hose and the nozzle 10. The water sprayed outwards by the nozzle 10 can rinse the surface of the photovoltaic panel, improving the cleaning effect of the photovoltaic panel.

[0034] A power module 13 is provided at the end of the horizontal plate 11 away from the auxiliary spring 12. The power module 13 is used to control the reciprocating movement of the horizontal plate 11. The power module 13 includes a movable wheel 131, which is fixed on the central rotating shaft of the cleaning roller 6. A first magnetic block 132 is fixed at the end of the blade in the circumferential direction of the movable wheel 131, and a second magnetic block 133 is provided on the side of the first magnetic block 132. The second magnetic block 133 is fixed on the limiting rod 134, and the limiting rod 134 is fixed on the horizontal plate 11. Multiple first magnetic blocks 132 are evenly distributed in the circumference of the movable wheel 131, and the magnetism of the first magnetic block 132 and the magnetism of the second magnetic block 133 are the same.

[0035] In this example, when the power module 13 realizes the swing of the nozzle 10, it drives the movable wheel 131 to rotate synchronously by the rotation of the cleaning roller 6. After the movable wheel 131 rotates, the distance between the first magnetic block 132 at its end and the second magnetic block 133 at the end of the limiting rod 134 changes. When the first magnetic block 132 and the second magnetic block 133 approach each other, the repulsive magnetic force between them allows the limiting rod 134 and the horizontal plate 11 to move below the mounting plate 5. When the movable wheel 131 rotates, the first magnetic block 132 and the second magnetic block 133 at its end move away from each other, and the limiting rod 134 and the horizontal plate 11 return to their original position under the action of the auxiliary spring 12. The reciprocating movement of the horizontal plate 11 can drive the nozzle 10 to swing.

[0036] Example 2:

[0037] The technical content disclosed in this embodiment differs from that in Embodiment 1 above in that: the power module 13 is composed of a pressure block 1301 and a pressure receiving frame 1302, and the pressure block 1301 is fixed on the inner side of the positioning frame 1. The pressure receiving frame 1302 is provided on the side of the pressure block 1301, and the pressure receiving frame 1302 is fixed on the end of the horizontal plate 11. The end of the pressure receiving frame 1302 near the pressure block 1301 and the pressure block 1301 are both set as arc-shaped structures.

[0038] In this embodiment, when the horizontal plate 11 is moved, the support block 2 moves the mounting plate 5 synchronously. After the mounting plate 5 moves, the horizontal plate 11 can move synchronously. When the horizontal plate 11 moves, the pressure frame 1302 on its side contacts and squeezes the pressure block 1301. By utilizing the action between the arc surfaces, the pressure frame 1302 and the horizontal plate 11 can move on the mounting plate 5. When the horizontal plate 11 and the mounting plate 5 move synchronously, and the pressure frame 1302 at the end of the horizontal plate 11 moves away from the pressure block 1301, the pressure frame 1302 and the horizontal plate 11 are reset under the action of the auxiliary spring 12. Thus, the reciprocating movement of the pressure frame 1302 and the horizontal plate 11 can be realized. The reciprocating movement of the horizontal plate 11 drives the nozzle 10 to move synchronously, thereby increasing the spraying range of the nozzle 10 on the water source.

[0039] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
