Description

Technical Field

[0001] This invention relates to the field of photovoltaic testing technology, specifically to a device for detecting defects in photovoltaic panels. Background Technology

[0002] Photovoltaic panels are a crucial component of photovoltaic (PV) power generation systems. Made of semiconductors, they convert light energy into electrical energy. With the trend towards new energy sources, PV power generation systems are becoming increasingly widespread. However, when PV panels are installed outdoors for power generation, numerous uncertainties can damage them. Therefore, to maintain their optimal working condition, regular inspections are necessary to check for defects such as microcracks. Defect detection of PV panels typically utilizes the principle of electroluminescence. During inspection, a forward current equal to or slightly higher than the short-circuit current is applied to the PV panel. This current excites electrons within the panel to transition to higher energy levels, causing them to emit light. A high-sensitivity camera then captures the infrared light emitted by the PV panel, and the resulting image is analyzed to determine if defects such as microcracks have appeared.

[0003] Chinese patent CN221328927U discloses a photovoltaic panel fault detection device, including a device base with casters at the lower end, a telescopic support frame and a translation frame at the upper end of the base, a translation motor on one side of the translation frame with a translation screw at the front end of the motor, a translation slide rod inside the translation frame, a detection device bracket outside the translation screw, an angle adjustment structure at the lower end of the detection device bracket, an infrared camera at the lower end of the angle adjustment structure, a cleaning bracket at the upper end of the device base, a cleaning frame at the upper end of the cleaning bracket, a moving motor at the upper end of the cleaning frame with a moving screw at the front end of the moving motor, a detachable cleaning structure outside the moving screw, a support plate on one side of the translation frame, a display screen at the upper end of the support plate, and a control panel at the upper end of the support plate. This utility model can not only adjust the detection angle but also clean the photovoltaic panel under test.

[0004] While the aforementioned existing technology can adjust the detection angle and clean the photovoltaic panel, it can only detect photovoltaic panels with relatively small areas. Even if the device has a telescopic mechanism to adjust the position of the infrared camera, when detecting larger photovoltaic panels, excessive extension of the telescopic mechanism can cause instability, leading to tipping over and damage to the photovoltaic panel. Furthermore, excessive extension of the telescopic mechanism causes significant shaking of the infrared camera when the device moves, hindering the capture of infrared light and resulting in poor data accuracy. In addition, when the telescopic mechanism can extend a long distance, its size becomes large, making it inconvenient to carry and transport.

[0005] To address the above issues, a device for detecting defects in photovoltaic panels is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a device for detecting defects in photovoltaic panels. By using this device, the problems mentioned in the background are solved: when inspecting large photovoltaic panels, the telescopic mechanism extends too far, causing instability in the center of gravity; and the infrared camera shakes significantly during movement, making it difficult to capture infrared light.

[0040] 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.

[0041] To address the technical issue of instability caused by excessive extension of the telescopic mechanism when inspecting large photovoltaic panels 23, such as... Figure 1 - Figure 11 As shown, the following preferred technical solutions are provided:

[0042] A device for detecting defects in photovoltaic panels includes a support device 1 and a photovoltaic module 2 mounted on the support device 1. The support device 1 supports and positions the photovoltaic module 2, which converts light energy into electrical energy. A pair of mounting boxes 3 are provided at the edge of the photovoltaic module 2, which support and fix numerous components. A steering component 4 is rotatably mounted inside the mounting box 3 to enable the steering function of the entire device. An adsorption component 9 is fixedly mounted on the outer wall of the steering component 4. The adsorption component 9 can generate negative pressure to adsorb the detection device onto the side wall of the photovoltaic module 2, so that the detection device will not fall off the photovoltaic module 2 during the detection process. A first moving component 6 and a second moving component 8 are rotatably mounted at both ends of the steering component 4, respectively. A first power component 5 and a second power component 7 are fixedly mounted on the side walls of both ends of the steering component 4, respectively. The first power component 5 and the first moving component 6 are meshed together, and the second power component 7 and the second moving component 8 are meshed together.

[0043] When installing the testing device, the first moving component 6 and the second moving component 8 are secured at the edge of the photovoltaic module 2. Then, the first power component 5 drives the first moving component 6 to rotate, and the second power component 7 drives the second moving component 8 to rotate, thereby enabling the testing device to move on the photovoltaic module 2 and perform full-area testing on the photovoltaic module 2. Several traction components 70 are also fixedly installed inside the mounting box 3. The far end of the traction component 70 is connected to the side wall of the steering component 4. When the testing device moves to the corner of the photovoltaic module 2 and needs to turn, the steering component 4 can be used to turn the testing device. After the turning is completed, the steering component 4 is restored to its original state by the traction component 70, so as not to affect the subsequent movement on the photovoltaic module 2.

[0044] The mounting box 3 has a first winding assembly 10 and a second winding assembly 20 respectively installed on its side wall. Cables 30 are wound around the first winding assembly 10 and the second winding assembly 20 respectively. A cleaning assembly 50 is movably installed on the cable 30. A detection assembly 60 is fixedly installed on the side wall of the cleaning assembly 50. A stabilizing assembly 40 is also fixedly installed on the side wall of the mounting box 3. The two first winding assemblies 10 and the two second winding assemblies 20 jointly wind up a cable 30. When the photovoltaic module 2 is inspected, the two first winding assemblies 10 rotate in opposite directions, and the two second winding assemblies 20 rotate in opposite directions, tautening the two cables 30. When the two cables 30 are taut, the cleaning assembly 50 can move stably on the two cables 30, thus stably cleaning the dirt on the surface of the photovoltaic module 2. After cleaning an area, the detection assembly 60 is controlled to inspect the photovoltaic module 2.

[0045] After testing one area of ​​photovoltaic module 2, when it needs to be moved to another area for testing, the cleaning component 50 is fixed by the stabilizing component 40 to reduce the shaking of the cleaning component 50 during the movement, thereby reducing the shaking of the testing component 60 during the movement. When the area to be tested is reached, the cleaning component 50 and the testing component 60 can quickly return to a stable state for testing. Compared with testing in an unstable state, this testing method has relatively high accuracy and the data is of reference value.

[0046] The photovoltaic module 2 includes a pair of vertical frames 21, which are fixedly connected by two horizontal frames 22. A photovoltaic panel 23 is embedded and fixedly installed on the inner sidewalls of the vertical frames 21 and the horizontal frames 22. The vertical frames 21 and the horizontal frames 22 not only support and fix the photovoltaic panel 23, but also protect the edges of the photovoltaic panel 23 from damage.

[0047] The support device 1 includes a mounting frame 11 fixedly installed on the back of the photovoltaic panel 23. A connector 12 is snapped onto the mounting frame 11. A support column 13 is rotatably installed on the connector 12. The bottom of the support column 13 is threaded to the ground. Since the connector 12 and the support column 13 are rotatably connected, it is used to adjust the tilt angle of the photovoltaic panel 23.

[0048] The mounting box 3 includes a box body 31, on which a mounting groove 32 is provided. By providing the mounting groove 32, some components can be installed in a concealed manner, which not only saves space but also protects the components inside the mounting groove 32 and extends the service life of the equipment.

[0049] The steering assembly 4 includes a first flip plate 41 and a second flip plate 42, which are respectively embedded and rotatably installed inside the mounting groove 32. The first flip plate 41 and the second flip plate 42 are elastically connected by a torsion spring 43. When the detection device moves to the corner of the vertical frame 21 and the horizontal frame 22, the flipping action of the first flip plate 41 and the second flip plate 42, in conjunction with the first power assembly 5, the second power assembly 7, the first moving assembly 6 and the second moving assembly 8, can achieve the steering effect of the detection device.

[0050] The first power assembly 5 includes a first motor 51 fixedly installed on the side wall of the first flip plate 41, and a first drive gear 52 is fixedly connected to the output end of the first motor 51.

[0051] The second power assembly 7 includes a second motor 71 fixedly installed on the side wall of the second flip plate 42, and a second drive gear 72 is fixedly connected to the output end of the second motor 71.

[0052] The first moving component 6 includes a first drive shaft 62 that is rotatably mounted through the first flip plate 41 at the end away from the second flip plate 42. A first driven gear 53 is fixedly sleeved on the outer wall of the first drive shaft 62. The first driving gear 52 and the first driven gear 53 are meshed together. First moving wheels 61 are fixedly mounted at both ends of the first drive shaft 62. The first motor 51 can drive the first moving wheels 61 to rotate through the first driving gear 52, the first driven gear 53 and the first drive shaft 62.

[0053] The second moving component 8 includes a second drive shaft 82 that is rotatably mounted through the second flip plate 42 at the end away from the first flip plate 41. A second driven gear 73 is fixedly sleeved on the outer wall of the second drive shaft 82. The second drive gear 72 and the second driven gear 73 are meshed together. Second moving wheels 81 are fixedly mounted at both ends of the second drive shaft 82. The second motor 71 can drive the second moving wheels 81 to rotate through the second drive gear 72, the second driven gear 73 and the second drive shaft 82. The rotation of the first moving wheel 61 and the second moving wheel 81 can drive the detection device to move on the vertical frame 21 or the horizontal frame 22.

[0054] The second movable wheel 81 includes a wheel body 811 fixedly installed at both ends of the second drive shaft 82. Several electric telescopic columns 812 are fixedly installed on the side wall of the inner cavity of the wheel body 811. The output ends of the several electric telescopic columns 812 are fixedly connected to a pressure plate 813. The pressure plate 813 is slidably disposed in the inner cavity of the wheel body 811. The outer wall of the wheel body 811 is tightly fitted with the side walls of the vertical frame 21 and the horizontal frame 22. The composition and connection method of the first movable wheel 61 and the second movable wheel 81 are the same.

[0055] The first drive shaft 62 and the second moving wheel 81 are placed at the edge of the vertical frame 21 or the horizontal frame 22. Then, the electric telescopic column 812 is activated, causing the pressure plate 813 to extend outward toward the wheel body 811. When the pressure plates 813 on both sides extend synchronously, they apply pressure to the outer walls of both sides of the vertical frame 21 or the horizontal frame 22, achieving a clamping effect on the vertical frame 21 or the horizontal frame 22. Under the action of the friction between the pressure plate 813 and the side walls of the vertical frame 21 or the horizontal frame 22, the detection device can be fixed at the edge of the vertical frame 21 or the horizontal frame 22, without... The device can be dropped to facilitate subsequent movement and testing of the photovoltaic panel 23. When the testing device needs to be removed, simply activate the electric telescopic column 812 to drive the pressure plate 813 to retract into the wheel body 811. At this time, the pressure applied by the pressure plate 813 to the outer walls on both sides of the vertical frame 21 or horizontal frame 22 is removed, and the testing device can slide off the edge of the vertical frame 21 or horizontal frame 22. With the above configuration, it is possible to clamp vertical frames 21 or horizontal frames 22 of different thicknesses, and then move on vertical frames 21 or horizontal frames 22 of different thicknesses, which has strong applicability.

[0056] The traction assembly 70 includes a pair of bases 701 fixedly installed on the inner wall of the mounting groove 32. A third motor 702 is fixedly installed on each of the two bases 701. The two third motors 702 are connected to the first flip plate 41 and the second flip plate 42 respectively by traction ropes 703.

[0057] The first winding assembly 10 includes a first winding motor 101 embedded and fixedly installed on the side wall of the housing 31. The output end of the first winding motor 101 is fixedly connected to a first winding drum 102, and a cable 30 is wound on the first winding drum 102.

[0058] The second winding assembly 20 includes a second winding motor 201 embedded and fixedly installed on the side wall of the housing 31. The output end of the second winding motor 201 is fixedly connected to a second winding drum 202, and a cable 30 is wound on the second winding drum 202.

[0059] Specifically, when testing the photovoltaic panel 23, one of the mounting boxes 3 is first attached to the edge of the horizontal frame 22. At this time, the electric telescopic column 812 is activated to drive the pressure plate 813 to extend outward toward the wheel body 811. When the pressure plates 813 on both sides extend synchronously, they will apply pressure to the outer walls on both sides of the horizontal frame 22, thereby achieving a clamping effect on the horizontal frame 22. Since the composition structure and connection method of the first moving wheel 61 and the second moving wheel 81 are the same, it means that the first moving wheel 61 will also apply pressure to the outer walls on both sides of the horizontal frame 22, and will also achieve a clamping effect on the horizontal frame 22. Under the action of the friction between the pressure plate 813 and the side wall of the horizontal frame 22, one of the mounting boxes 3 can be fixed at the edge of the horizontal frame 22, and the adsorption component 9 is activated to generate negative pressure, firmly adsorbing the mounting box 3 onto the outer wall of the horizontal frame 22.

[0060] Then, another mounting box 3 is attached to the edge of the vertical frame 21. Similarly, the pneumatically activated electric telescopic column 812 drives the pressure plate 813 to extend outward toward the wheel body 811. When the pressure plates 813 on both sides extend synchronously, they will apply pressure to the outer walls on both sides of the vertical frame 21. Under the action of the friction between the pressure plate 813 and the side wall of the vertical frame 21, the other mounting box 3 is fixed to the lower end of the vertical frame 21. Similarly, the adsorption component 9 is activated to generate negative pressure, firmly adsorbing the mounting box 3 onto the outer wall of the vertical frame 21. Then, the first motor 51 and the second motor 71 are activated respectively to drive the first moving wheel 61 and the second moving wheel 81 to rotate on the vertical frame 21, thereby moving the mounting box 3 from the lower end of the vertical frame 21 to the upper end of the vertical frame 21.

[0061] When the device moves to the corner between the horizontal frame 22 and the vertical frame 21, the first motor 51 and the second motor 71 stop operating. At this time, the first moving wheel 61 releases the pressure applied to the outer walls on both sides of the vertical frame 21, thus losing its clamping effect on the vertical frame 21. Then, the third motor 702, which is connected to the first flipping plate 41 via the traction rope 703, starts operating, releasing the traction rope 703. At this time, under the elastic force of the torsion spring 43, the first flipping plate 41 will carry the first moving assembly 6 towards the top horizontal frame 22. The first rotating plate 41 is flipped in the direction of rotation until it adheres to the top wall of the vertical frame 21. This causes the first moving wheel 61 to resume applying pressure to the outer walls of both sides of the vertical frame 21 and to clamp the side wall of the top horizontal frame 22 again. Due to the negative pressure generated by the adsorption component 9 on the outer wall of the first rotating plate 41, the first rotating plate 41 is firmly adhered to the top wall of the vertical frame 21. Then, after closing the adsorption component 9 on the outer wall of the second rotating plate 42, the electric telescopic column 812 is activated, driving the pressure plate 813 towards the wheel. When 811 retracts internally, the pressure exerted by the pressure plate 813 on the outer walls of both sides of the vertical frame 21 is removed, losing its clamping effect. Then, the third motor 702, connected to the first flipping plate 41 via the traction rope 703, begins to tighten the traction rope 703, causing the mounting box 3 to flip towards the direction closer to the top horizontal frame 22. After tightening to the correct position, the mounting box 3 completes its directional change. At this point, the first motor 51 and the second motor 71 are started to operate, causing the mounting box 3 to move on the top horizontal frame 22. When the second moving wheel 81 moves to the edge of the side wall of the top horizontal frame 22, the electric telescopic column 812 is activated to drive the pressure plate 813 to extend outward from the wheel body 811. When the pressure plates 813 on both sides extend synchronously, they apply pressure to the outer walls of both sides of the top horizontal frame 22, thereby achieving a clamping effect on the top horizontal frame 22. After the adsorption component 9 on the outer wall of the second flipping plate 42 is opened, the mounting box 3 can be firmly adsorbed, allowing the mounting box 3 to move smoothly on the top horizontal frame 22.

[0062] When the two mounting boxes 3 are moved to the stacked position, the two first winding motors 101 rotate in opposite directions, driving the first winding drum 102 to rotate in opposite directions to tighten the cable 30. Then, the two second winding motors 201 rotate in the same opposite direction, driving the second winding drum 202 to tighten the cable 30. When the two cables 30 are fully tightened, a tension will be generated between the two mounting boxes 3, which will enable the two mounting boxes 3 to move stably on the vertical frame 21 or the horizontal frame 22, which will help improve the stability of the detection device when it moves. After the two cables 30 are fully tightened, the cleaning component 50 can drive the detection component 60 to move on the cable 30, thereby performing full-area detection on the photovoltaic panel 23. After the detection is completed, the above steps can be reversed to recycle the device.

[0063] With the above setup, when inspecting large-area photovoltaic panels 23, no personnel are required to move the inspection device. Moreover, when the photovoltaic panels 23 are too high for personnel to touch or for the inspection device to be installed, this setup allows the device to be moved from the bottom to the top of the photovoltaic panel 23 before inspection. This setup not only saves manpower but is also suitable for inspecting photovoltaic panels 23 with various installation heights and installation methods, demonstrating good applicability and flexibility. After use, the device can be rolled up to reduce its size, making it easy to carry and transport.

[0064] To address the technical problem of significant shaking of the infrared camera 606 during the movement of the detection device, which hinders the capture of infrared light, such as... Figure 1 - Figure 2 , Figure 4 - Figure 5 and Figure 12 - Figure 14 As shown, the following preferred technical solutions are provided:

[0065] The stabilizing component 40 includes a mounting plate 401 fixedly installed on the outer side wall of the housing 31. A telescopic rod 402 is fixedly installed on the side wall of the mounting plate 401 facing the cleaning component 50. An electromagnet 403 is fixedly installed at the output end of the telescopic rod 402.

[0066] The cleaning assembly 50 includes a collection box 501, on which a pair of through slots 502 are provided. Several pairs of drive wheels 503 are rotatably installed in the inner cavity of the through slots 502. A cable 30 passes through the gap between the two drive wheels 503. A permanent magnet 504 is fixedly installed on the side wall of the collection box 501 facing the electromagnet 403. The permanent magnet 504 is aligned with the electromagnet 403. Several vacuum cleaners 505 are connected to the side wall of the collection box 501 facing the photovoltaic panel 23.

[0067] The detection component 60 includes a pair of electric push rods 601 fixedly installed on the outer wall of the collection box 501. The output ends of the two electric push rods 601 are jointly fixedly installed on a support plate 602. A stabilization cloud platform 603 is fixedly installed on the outer wall of the support plate 602. The stabilization cloud platform 603 has a stabilization function, which is beneficial to improving the accuracy of shooting. The stabilization principle of the stabilization cloud platform 603 is existing technology and will not be explained in detail here. A mounting bracket 604 is rotatably installed on the upper end of the stabilization cloud platform 603. A clamping frame 605 is rotatably installed inside the mounting bracket 604. An infrared camera 606 is clamped inside the clamping frame 605. A servo motor 607 is fixedly installed on the side wall of the mounting bracket 604. The output end of the servo motor 607 passes through the side wall of the mounting bracket 604 and is fixedly connected to the clamping frame 605.

[0068] Specifically, before inspecting the photovoltaic panel 23, the drive wheel 503 drives the collection box 501 to move along the two cables 30. During the movement, the vacuum cleaner 505 sucks the dust and impurities on the surface of the photovoltaic panel 23 into the collection box 501 for collection. After cleaning one area, the electric top rod 601 is activated to adjust the anti-shake cloud platform 603 and the infrared camera 606 to a suitable height. Then, the servo motor 607 drives the clamping frame 605 and the infrared camera 606 to rotate inside the mounting bracket 604, adjusting the infrared camera 606 to a suitable shooting angle for shooting. After inspecting one area of ​​the photovoltaic panel 23, when it is necessary to move to another area for inspection, the telescopic rod 402 near the collection box 501... The telescopic rod 402 extends until it contacts the permanent magnet 504. Then, it is energized, creating an attraction between the electromagnet 403 and the permanent magnet 504, thus fixing the cleaning assembly 50 as a whole and reducing the shaking of the cleaning assembly 50 and the detection assembly 60 during movement. When it reaches the area to be detected, the cleaning assembly 50 and the detection assembly 60 quickly return to a stable state, allowing the infrared camera 606 to quickly return to a stable state to detect the photovoltaic panel 23. Compared to detection in an unstable state, this detection method has relatively higher accuracy and the data is more meaningful. After reaching the detection position, the permanent magnet 504 is de-energized, and the telescopic rod 402 retracts to its original position to prevent affecting the normal operation of the cleaning assembly 50.
