Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a device for cleaning dust from photovoltaic panels. Background Technology

[0002] The widespread application of photovoltaic (PV) power generation technology has made surface dust on PV panels a significant factor affecting their power generation efficiency, especially in arid and dusty regions where dust accumulation severely impacts sunlight transmittance, thus reducing power generation. Therefore, cleaning PV panels is crucial. Traditional cleaning methods such as manual, mechanical, and water-based cleaning suffer from low efficiency, high costs, and water waste. In recent years, new technologies such as dry cleaning, automated robots, airflow cleaning, and ultrasonic cleaning have emerged, not only improving cleaning efficiency but also reducing water consumption, making them particularly suitable for resource-scarce or environmentally harsh areas. In the future, PV panel cleaning devices will develop towards intelligence, energy saving, and low cost. Leveraging artificial intelligence, machine learning, and high-efficiency materials technologies, these devices will possess greater adaptability and efficiency, thereby promoting the sustainable development of the PV industry.

[0003] However, in practical applications of existing solutions, the surface of photovoltaic panels is typically cleaned manually using handheld cleaning tools. This method is inefficient, especially in large-scale photovoltaic power plants, where manual cleaning often requires significant manpower and resources and is slow. Because photovoltaic panels are usually large, manual cleaning cannot be completed quickly, resulting in long cleaning cycles and impacting the power generation efficiency of the panels. Furthermore, improper use of handheld cleaning tools can scratch or damage the surface of the photovoltaic panels. The surface of photovoltaic panels typically has an anti-reflective coating; if the cleaning tools are too rough or used improperly, this coating may be damaged, affecting the performance and lifespan of the photovoltaic panels.

[0004] Therefore, this utility model provides a photovoltaic panel dust cleaning device. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] Reference Figure 1-9 A photovoltaic panel dust cleaning device includes a storage compartment 1. A power component is provided on one side of the storage compartment 1. A connecting plate 52 is provided at the power end of the power component. A photovoltaic panel flipping component is provided on the outside of the connecting plate 52. The power component and the photovoltaic panel flipping component are connected through the connecting plate 52. A solar panel 13 is provided on the photovoltaic panel flipping component. A cleaning box 3 is fixedly connected to the outside of the storage compartment 1. The cleaning box 3 is fixed through the storage compartment 1. A surface cleaning component is provided on the inside of the cleaning box 3. A cleaning rod 35 is provided at the cleaning end of the surface cleaning component. The cleaning rod 35 is slidably connected to the solar panel 13.

[0030] The power assembly includes a third motor 5, which is fixedly connected to the outer wall of the storage compartment 1. The storage compartment 1 controls the third motor 5. A pulley 51 is rotatably connected to the inner wall of the storage compartment 1. The storage compartment 1 simultaneously limits the drive pulley and driven pulley in the pulley 51, causing them to rotate inside the storage compartment 1, thereby driving the belt. The drive pulley in the pulley 51 is fixedly connected to the output end of the third motor 5. The third motor 5 drives the drive pulley in the pulley 51 to rotate, thereby driving the belt to rotate. The middle section of the pulley 51 is fixedly connected to the connecting plate 52, fixing the connecting plate 52 and simultaneously driving the connecting plate 52 to rotate synchronously.

[0031] The photovoltaic panel rotation module includes a support frame 22, which is fixedly connected to a connecting plate 52. The connecting plate 52 fixes the support frame 22, allowing the support frame 22 to move synchronously as the connecting plate 52 moves. A first motor 23 is fixedly connected to the inner side of the support frame 22, and the first motor 23 is fixedly connected to the support frame 22. A first transmission rod 24 is fixedly connected to the output end of the first motor 23, and the first transmission rod 24 is fixed to the first motor 23. Simultaneously, the first motor 23 drives the first transmission rod 24 to rotate. A second transmission rod 24 is rotatably connected to the outer side of the other end of the first transmission rod 24. The transmission rod 25 has a transmission frame 26 rotatably connected to its other end. The first transmission rod 24 and the transmission frame 26 are connected through the second transmission rod 25. A rotating frame 27 is fixedly connected to the outside of the transmission frame 26. The bottom of the outer end of the rotating frame 27 near the transmission frame 26 is rotatably connected to the support frame 22. The support frame 22 limits the outer end of the rotating frame 27. Thus, while the first motor 23 drives the first transmission rod 24 to rotate, the second transmission rod 25 and the transmission frame 26 drive the rotating frame 27 to rotate around the connection point between the support frame 22 and the rotating frame 27, thereby causing it to flip.

[0032] The bottom of the support frame 22 is fixedly connected to a uniformly distributed slider 21. The slider 21 is fixed by the support frame 22. The inner side of the slider 21 is slidably connected to a slide rail 2. The slide rail 2 is fixedly connected to the inner wall of the storage compartment 1. The slide rail 2 is fixed by the storage compartment 1. At the same time, the slide rail 2 limits the storage compartment 1, so that the slider 21 can only move at the top of the slide rail 2 and along the slide rail 2.

[0033] The surface cleaning assembly includes a cleaning box 3, which is fixedly connected to a storage compartment 1. The storage compartment 1 secures the cleaning box 3. Corresponding protective nets 31 are fixedly connected to both sides of the exterior of the cleaning box 3, securing the protective nets 31. Corresponding cylinders 32 are fixedly connected to both sides of the top wall of the cleaning box 3, supporting and securing the cylinders 32. A sealing cylinder 33 is fixedly connected to the lifting end of the cylinder 32, securing the sealing cylinder 33 and simultaneously driving the sealing cylinder 33 to rise and fall. A second motor 34 is fixedly connected to both ends, and the second motor 34 on both sides is simultaneously fixed by a sealing cylinder 33. A cleaning rod 35 is fixedly connected to the output end of the second motor 34, and the cleaning rod 35 is rotated by the second motor 34. An inner liner sleeve 36 is fixedly connected to the inside of the sealing cylinder 33, and the inner liner sleeve 36 is fixed by the sealing cylinder 33. The inner liner sleeve 36 has evenly distributed ventilation holes, so that the dust cleaned by the cleaning rod 35 can be sucked into the sealing cylinder 33. The inner liner sleeve 36 is rotatably connected to the cleaning rod 35, and the dust is drawn into the sealing cylinder 33 by the inner liner sleeve 36. The bushing 36 limits the cleaning rod 35, which is slidably connected to the solar panel 13 through a through hole in the bottom wall of the bushing 36. The bottom end of the bushing 36 has a through hole, allowing the cleaning rod 35 to contact the surface of the solar panel 13. The rotation of the cleaning rod 35 cleans the dust from the surface of the solar panel 13. Air inlets 37 are located on both sides of the bottom wall of the sealing cylinder 33, on either side of the cleaning rod 35. Exhaust boxes 4 are fixedly connected to both ends of the sealing cylinder 33, and evenly distributed exhaust fans 4 are fixedly connected to the inside of the exhaust boxes 4. 2. A filter screen 41 is detachably connected to the top wall of the exhaust box 4. The exhaust fan 42 inside the exhaust box 4 draws air from the inside of the sealing cylinder 33, while external air enters the sealing cylinder 33 through the air inlet 37 and the through hole at the bottom of the inner liner sleeve 36. The air carries dust into the sealing cylinder 33 and continues to move upward into the exhaust box 4. The dust is then filtered by the filter screen 41, and the air is discharged. The filter screen 41 is fixed inside the exhaust box 4 by bolts, so the filter screen 41 can be removed for cleaning by removing the bolts.

[0034] The inner wall of the storage compartment 1 has opposing grooves 11 on both sides. A limit rod 12 is slidably connected to the inner side of the groove 11. The limit rod 12 is rotatably connected to the solar panel 13. The limit rod 12 is connected to the solar panel 13, and the limit rod 12 is limited by the groove 11, so that the limit rod 12 can only slide within the groove 11, thereby limiting the movement distance of the solar panel 13.

[0035] Specifically, during operation, this photovoltaic panel dust cleaning device works as follows: After the end of each workday, the third motor 5 drives the pulley 51 to rotate. Simultaneously, the pulley 51, via the connecting plate 52, drives the support frame 22 to move inward towards the storage compartment 1. The support frame 22 also drives the top solar panel 13 to move synchronously. During this process, the first motor 23 drives the first transmission rod 24 to rotate, which in turn drives the rotating frame 27 to rotate via the second transmission rod 25 and the transmission frame 26. This rotating frame 27 then drives the solar panel 13 to rotate synchronously, thus leveling the solar panel 13. Afterward, the solar panel 13 moves inward towards the storage compartment 1, and then the cylinder 32 drives the bottom seal... The structure inside the cylinder 33 and the sealing cylinder 33 moves towards the top of the solar panel 13. Then, the second motor 34 drives the cleaning rod 35 to rotate. After the cleaning rod 35 comes into contact with the surface of the solar panel 13, the rotation of the cleaning rod 35 cleans and lifts the dust on the surface of the solar panel 13. At the same time, the exhaust fan 42 draws air from the inside of the sealing cylinder 33 and allows outside air to enter through the air inlet 37 and the through hole at the bottom of the inner sleeve 36, so that the air flows and carries the dust to the inside of the sealing cylinder 33. Then, the dust is drawn into the exhaust box 4 by the exhaust fan 42, and the dust in the air is filtered through the filter screen 41. The air is then discharged, completing the cleaning process.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
