TECHNICAL FIELD

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

[0031] Please see Figures 1 to 7 This invention provides a technical solution:

[0032] A fault inspection device for photovoltaic panels in a solar photovoltaic power station includes a frame 11 and an infrared scanner 30. A toothed plate 29 for supporting the infrared scanner 30 is provided on the upper side of the frame 11. A drive assembly is provided on the lower side of the frame 11 to drive the frame 11 to move linearly along the surface of the photovoltaic panel. An adjustment assembly is provided between the toothed plate 29 and the frame 11. The adjustment assembly includes ear plates 14 fixedly connected to the outer surface of the upper end of the frame 11. A passive shaft 21 is rotatably connected between two sets of ear plates 14. A magnetic ring 35 is fixedly connected to the outer surface of the passive shaft 21. A gear 32 is magnetically connected to the outer surface of the magnetic ring 35. The gear 32 meshes with the toothed plate 29 for transmission. A support tube 28 is fixedly connected to the outer surface of the passive shaft 21. The toothed plate 29 is located inside the support tube 28 and slidably connected to the support tube 28.

[0033] A motor 27 is fixedly connected to the outer surface of the left end of the ear plate 14. A drive shaft 31 is fixedly connected to the rear end of the output shaft of the motor 27. The drive shaft 31 passes through the two sets of ear plates 14 and is rotatably connected to the ear plates 14. A gear 2 34 is fixedly connected to the outer surface of the drive shaft 31. The gear 2 34 meshes with the gear 1 32 for transmission. A support plate 46 is fixedly connected to the outer surface of the upper end of the gear plate 29. The outer surface of the right end of the support plate 46 is fixedly connected to the infrared scanner 30.

[0034] By adopting the above technical solution, when the photovoltaic panel fault inspection device is working, it is first placed on the upper side of the photovoltaic panel. The frame 11 is rotated and supported by the passive shaft 21 through the ear plate 14, and the passive shaft 21 supports the support tube 28. The toothed plate 29 is located inside the support tube 28 and can slide linearly. The upper end of the toothed plate 29 is supported by the support plate 46. During the movement of the frame 11 on the upper side of the photovoltaic panel, the infrared scanner 30 scans the photovoltaic panel below it. The infrared scanner 30 identifies faults by capturing the temperature distribution differences on the surface of the photovoltaic panel. In order to obtain better light intensity for the photovoltaic panel, some photovoltaic panels will maintain a certain tilt angle during installation. In order to keep the angle and distance between the infrared scanner 30 and the photovoltaic panel within an appropriate range, an adjustment component is set. When adjusting the angle of the infrared scanner 30, the operator starts... The motor 27 drives the drive shaft 31 and gear 32 to rotate synchronously, while simultaneously conducting electricity through the magnetic ring 35. Gear 34 is attracted to the surface of the magnetic ring 35 under the magnetic force. Gear 32 and gear 34 mesh and are connected. During rotation, gear 32 drives gear 34 to rotate synchronously. Gear 34 drives the passive shaft 21 to rotate synchronously through the magnetic ring 35. The support tube 28 is fixedly connected to the passive shaft 21 and rotates synchronously with the passive shaft 21 at a certain angle. The support tube 28 drives the toothed plate 29 and infrared scanner 30 to rotate around the passive shaft 21, thereby adjusting the scanning angle of the infrared scanner 30. This helps to maintain the angle between the infrared scanner 30 and the photovoltaic panel within an appropriate range, thus effectively improving the detection accuracy of the photovoltaic panel and increasing the application range of the inspection device.

[0035] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, a telescopic assembly is provided on the outside of the support tube 28. The telescopic assembly includes a magnetic sleeve 33 that is fixedly connected to the inner surface of the ear plate 14. The magnetic sleeve 33 is sleeved on the outside of the passive shaft 21. The end of the magnetic sleeve 33 away from the ear plate 14 is in contact with the outer surface of the support tube 28. Both the upper and lower ends of the support tube 28 are open. The support tube 28 is made of a hollow rectangular tube.

[0036] By adopting the above technical solution, a telescopic component is set up to flexibly adjust the height of the infrared scanner 30. During operation, the magnetic sleeve 33 is electrically conductive, and the support tube 28 remains relatively stationary with the ear plate 14 under the magnetic attraction of the magnetic sleeve 33. Then, the magnetic ring 35 is de-energized. At this time, as the gear 1 32 drives the gear 2 34 to rotate, the toothed plate 29 meshes and is connected to the gear 2 34. As the gear 2 34 rotates, it drives the toothed plate 29 to slide linearly inside the support tube 28. During the movement, the toothed plate 29 drives the infrared scanner 30 to move synchronously through the support plate 46. By adjusting the height of the infrared scanner 30, the distance between the infrared scanner 30 and the photovoltaic panel can be maintained within an appropriate range, thereby effectively providing the movement stability and practicality of the fault inspection device.

[0037] Specifically, such as Figure 3 As shown, the drive assembly includes a mounting plate 16 fixedly connected to the outer surface of the lower end of the frame 11. The outer surface of the mounting plate 16 is rotatably connected to a drive rod 15 via a bearing. There are two sets of drive rods 15, which are distributed in parallel. Both ends of the drive rod 15 are fixedly connected to drive wheels 17. The outer surface of the drive wheels 17 is meshed with a track 18.

[0038] A fixing plate 12 is fixedly connected to the outer surface of the right end of the frame 11. A motor 19 is fixedly connected to the outer surface of the fixing plate 12. The output shaft of the motor 19 is fixedly connected to the right drive rod 15. The motor 19 is a dual-axis motor. The track 18 is made of elastic rubber material.

[0039] By adopting the above technical solution, a drive assembly is set up to enable the inspection device to move linearly on the surface of the photovoltaic panel. During operation, the motor 19 is started and the output shaft of the motor 19 drives the right drive rod 15 to rotate synchronously. The drive rod 15 drives the drive wheel 17 to rotate synchronously. The track 18 is connected to the drive wheel 17 through meshing transmission. As the drive wheel 17 rotates, it drives the track 18 to rotate. The lower surface of the track 18 contacts the upper surface of the photovoltaic panel, which can drive the inspection device to move linearly along the upper surface of the photovoltaic panel. The track 18 can effectively increase the contact area with the surface of the photovoltaic panel, thereby reducing the risk of excessive pressure on the surface of the photovoltaic panel. The elastic rubber material not only increases the friction with the surface of the photovoltaic panel, but also reduces the wear of the track 18 on the photovoltaic panel, thereby improving the safety and stability of the inspection device during movement.

[0040] Specifically, such as Figure 4 and Figure 7As shown, a cleaning component is provided on the left side of the fixing plate 12. The cleaning component includes a protective cover 13 fixedly connected to the outer surface of the left end of the fixing plate 12. A guide groove 26 is provided through the outer surface of the protective cover 13. A support rod 42 is slidably connected to the inner side of the guide groove 26. A brush roller 23 is fixedly connected to the outer surface of the support rod 42. The lower side of the outer surface of the brush roller 23 is in rotatable contact with the upper outer surface of the photovoltaic plate.

[0041] The drive rod 15 on the right side is symmetrically fixedly connected to two ends of a movable rod 20. The movable rod 20 and the front end of the support rod 42 are both fixedly connected to a synchronous wheel 25. The outer surface of the synchronous wheel 25 is meshed with a synchronous belt 24. The brush roller 23 is made of soft brush. The guide groove 26 is arc-shaped, and the center of the guide groove 26 coincides with the axis of the movable rod 20.

[0042] By adopting the above technical solution, in order to improve the functionality and working efficiency of the photovoltaic panel inspection device, a cleaning component is set up. During the rotation of the drive rod 15, the movable rod 20 will rotate synchronously. The movable rod 20 will drive the synchronous wheel 25 to rotate synchronously. The fixed plate 12 is fixedly installed on the protective cover 13. The guide groove 26 on the surface of the protective cover 13 is used to slide support the support rod 42. The support rod 42 will fix and support the brush roller 23. The synchronous belt 24 is meshed and connected to the two sets of synchronous wheels 25, which will drive the two sets of synchronous wheels 25 to rotate at the same linear speed. The synchronous wheel 25 on the front side of the support rod 42 will drive the brush roller 23 to rotate synchronously through the support rod 42. During the rotation, the brush roller 23 will rotate and contact the upper surface of the photovoltaic panel. The soft brush roller 23 can rotate and clean the dust on the surface of the photovoltaic panel, thereby effectively reducing the impact of dust on the photovoltaic panel surface on the light reception efficiency, and thus ensuring the power generation efficiency of the photovoltaic module to a certain extent. By cleaning the surface of the photovoltaic panel simultaneously during the inspection, not only can the inspection and cleaning efficiency of the photovoltaic panel be effectively improved, but the functionality of the inspection device can also be effectively improved.

[0043] Specifically, such as Figure 4 and Figure 6 As shown, a marking assembly is provided on the inner side of the protective cover 13. The marking assembly includes a movable sleeve 43 fixedly connected to the outer surface of the movable rod 20. A swing rod 22 is rotatably connected to the outer surface of the movable sleeve 43. The swing rod 22 passes through the interior of the protective cover 13 and is rotatably connected to the support rod 42. A limiting groove 44 is provided through the outer surface of the fixed plate 12. An electric push rod 45 is fixedly connected to the lower side of the inner surface of the limiting groove 44. The output end of the electric push rod 45 slides in contact with the lower outer surface of the swing rod 22.

[0044] A compression sleeve 39 is fixedly connected to the inner surface of the guide groove 26. A liquid storage cavity 38 is embedded in the inner side of the protective cover 13. The inside of the compression sleeve 39 is connected to the liquid storage cavity 38. The compression sleeve 39 is made of elastic wear-resistant material. A liquid inlet groove 36 is opened through the outer surface of the upper end of the protective cover 13. The lower end of the liquid inlet groove 36 is connected to the inside of the liquid storage cavity 38.

[0045] A one-way valve 37 is fixedly connected to the inner side of the liquid inlet 36. A liquid outlet 40 is opened through the outer surface of the lower end of the protective cover 13. A pressure nozzle 41 is fixedly connected to the inner side of the liquid outlet 40. The liquid storage chamber 38 is filled with water-soluble pigment. The support rod 42 slides in contact with the outer surface of the extrusion sleeve 39. The swing rod 22 slides in contact with the inner surface of the limiting groove 44.

[0046] By adopting the above technical solution, a marking component is set up to facilitate the marking and replacement of faulty photovoltaic panels. During operation, the movable rod 20 supports the swing rod 22 through the movable sleeve 43. The swing rod 22 extends into the protective cover 13 through the limiting groove 44 and is rotatably connected to the support rod 42. When the infrared scanner 30 detects a fault in the photovoltaic panel, the inspection device control system controls the electric push rod 45 to start running. The limiting groove 44 is used to fix the electric push rod 45. The upper end of the electric push rod 45 slides in contact with the lower surface of the swing rod 22. As the upper end of the electric push rod 45 gradually extends, the electric push rod 45 pushes the swing rod 22. At this time, the swing rod 22 will rotate around the movable rod 20. When the fulcrum rotates, the swing rod 22 will drive the support rod 42 to slide upward along the inside of the guide groove 26. During the movement of the support rod 42, the brush roller 23 will move upward synchronously. At this time, the brush roller 23 will disengage from the upper surface of the photovoltaic panel, thereby stopping the brush roller 23 from cleaning the photovoltaic panel. This not only improves the cleaning accuracy of the inspection device, but also reduces the extra wear of the brush roller 23 to a certain extent. The center of the arc of the guide groove 26 coincides with the axis of the movable rod 20, so that when the support rod 42 slides inside the guide groove 26, the tension between the synchronous belt 24 and the synchronous pulley 25 is maintained within an appropriate range, thereby reducing the risk of the synchronous belt 24 slipping or breaking.

[0047] Before the inspection device operates, an appropriate amount of water-soluble pigment is injected into the storage chamber 38 through the inlet tank 36. When the support rod 42 moves inside the guide groove 26, the one-way valve 37 inside the inlet tank 36 can achieve one-way sealing to prevent the pigment from flowing back upward. When the support rod 42 moves upward inside the guide groove 26, the support rod 42 will slide into contact with the outer surface of the extrusion sleeve 39, and the extrusion sleeve 39 will be extruded by the support rod 42. At this time, the extrusion sleeve 39 will undergo elastic deformation and indent. During the deformation process, the extrusion sleeve 39 will extrude the pigment inside the storage chamber 38. At this time, the pigment inside the outlet tank 40 is sprayed downward through the pressure nozzle 41 under pressure. The sprayed pigment can mark the faulty photovoltaic panel, which makes it easier for maintenance personnel to accurately repair and replace the faulty photovoltaic panel. The pigment is made of water-soluble material and can be quickly cleaned with water, which can effectively reduce the impact of pigment on the photosensitive accuracy of the photovoltaic panel.

[0048] Working Principle: When the photovoltaic panel inspection device is working, it is first placed on the upper surface of the photovoltaic panel. The output shaft of motor 19 drives the right drive rod 15 to rotate synchronously. The drive rod 15 drives the drive wheel 17 to rotate synchronously. As the drive wheel 17 rotates, it drives the track 18 to rotate, thereby driving the inspection device to move linearly along the upper surface of the photovoltaic panel. When adjusting the height and angle of the infrared scanner 30, gear 2 34 is attracted to the surface of magnetic ring 35 under the magnetic force of magnetic ring 35. Gear 2 34 drives the passive shaft 21 to rotate synchronously through magnetic ring 35. The support tube 28 is fixedly connected to the passive shaft 21 and will rotate synchronously with the passive shaft 21 at a certain angle. The toothed plate 29 is meshed with gear 2 34 for transmission. As gear 2 34 rotates, it drives the toothed plate 29 to rotate synchronously with the support tube 28. The internal linear sliding mechanism allows the toothed plate 29 to move synchronously with the infrared scanner 30 via the support plate 46. By adjusting the height of the infrared scanner 30, the synchronous wheel 25 on the front side of the support rod 42 drives the brush roller 23 to rotate synchronously via the support rod 42. During rotation, the brush roller 23 rotates and contacts the upper surface of the photovoltaic panel. The soft brush roller 23 can clean the dust on the surface of the photovoltaic panel. When the support rod 42 moves upward inside the guide groove 26, it slides and contacts the outer surface of the extrusion sleeve 39. During the deformation of the extrusion sleeve 39, it extrudes the pigment inside the liquid storage chamber 38. At this time, the pigment is sprayed downward through the pressure nozzle 41 under pressure to mark the faulty photovoltaic panel, which makes it easier for maintenance personnel to accurately repair and replace the faulty photovoltaic panel.
