Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic detection, and in particular to a device for detecting defects of photovoltaic panels. Background Art

[0002] Photovoltaic panels are important components of photovoltaic power generation systems. They are components made of semiconductors and are used to convert light energy into electrical energy. Under the trend of new energy, photovoltaic power generation systems are becoming more and more widely used. When photovoltaic panels are installed outdoors to generate electricity, there will be many uncertain factors that may cause damage to the photovoltaic panels. Therefore, in order to maintain the photovoltaic panels in good working condition, staff are required to regularly inspect the photovoltaic panels to check whether there are any hidden cracks or other damage to the photovoltaic panels. When defect detection is performed on photovoltaic panels, the principle of electroluminescence is usually used for detection. In the process of detecting photovoltaic panels, a forward current equal to or slightly higher than its short-circuit current is first applied to the photovoltaic panel. The current will excite the electrons inside the photovoltaic panel to transition to a high-energy state, causing these electrons to begin to emit light. Then, a high-sensitivity camera is used to capture the infrared light emitted by the photovoltaic panel, and the formed image is analyzed to determine whether there are any hidden cracks or other defects in the photovoltaic panel.

The utility model can not only adjust the detection angle, but also clean the photovoltaic panel to be tested.

[0004] Although the above-mentioned prior art can adjust the detection angle and clean the photovoltaic panel, the device 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 photovoltaic panels with larger areas, the telescopic mechanism will be extended too long, which will cause unstable center of gravity and easy rollover, and will also cause damage to the photovoltaic panel; and if the telescopic mechanism is extended too long, when the device moves, the infrared camera will shake more violently, which is not conducive to capturing infrared light and has poor data accuracy; in addition, when the telescopic mechanism can be extended for a long distance, the telescopic mechanism will be large in size and inconvenient to carry and transport.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In order to solve the technical problem that when testing a photovoltaic panel 23 with a large area, the telescopic mechanism may be extended too long, which may cause an unstable center of gravity. Figure 1- Fig.11 As shown, the following preferred technical solutions are provided: A device for detecting defects in photovoltaic panels comprises a supporting device 1 and a photovoltaic assembly 2 arranged on the supporting device 1, wherein the supporting device 1 supports and positions the photovoltaic assembly 2, and the photovoltaic assembly 2 is used to convert light energy into electrical energy. A pair of mounting boxes 3 are arranged at the edge of the photovoltaic assembly 2, and the mounting boxes 3 are used to support and fix a plurality of components. A steering assembly 4 is rotatably arranged inside the mounting box 3, and the steering assembly 4 is used to realize the steering function of the entire device. An adsorption assembly 9 is fixedly arranged on the outer side wall of the steering assembly 4, and the adsorption assembly 9 can generate negative pressure to adsorb the detection device on the side wall of the photovoltaic assembly 2, so that the detection device will not fall off the photovoltaic assembly 2 during the detection process. A first moving assembly 6 and a second moving assembly 8 are rotatably arranged at both ends of the steering assembly 4, and a first power assembly 5 and a second power assembly 7 are fixedly arranged on the side walls of both ends of the steering assembly 4, respectively. The first power assembly 5 and the first moving assembly 6 are meshedly connected, and the second power assembly 7 and the second moving assembly 8 are meshedly connected.

[0022] When installing the detection device, the first movable component 6 and the second movable component 8 are clamped at the edge of the photovoltaic component 2, and then the first power component 5 can drive the first movable component 6 to rotate, and the second power component 7 can drive the second movable component 8 to rotate, so that the detection device can move on the photovoltaic component 2 to perform full-area detection on the photovoltaic component 2. A plurality of traction components 70 are also fixedly arranged inside the installation box 3. The far end of the traction component 70 is connected to the side wall of the steering component 4. When the detection device moves to the turning point of the photovoltaic component 2 and needs to turn, the steering of the detection device can be achieved through the operation of the steering component 4. After the steering is completed, the steering component 4 is restored to its original state through the traction component 70, which will not affect the subsequent movement on the photovoltaic component 2.

[0023] A first winding assembly 10 and a second winding assembly 20 are respectively arranged on the side walls of the installation box 3, and cables 30 are respectively wound on the first winding assembly 10 and the second winding assembly 20, and a cleaning assembly 50 is movably arranged on the cable 30. A detection assembly 60 is fixedly arranged on the side wall of the cleaning assembly 50, and a stabilizing assembly 40 is also fixedly arranged on the side wall of the installation box 3. The above-mentioned two first winding assemblies 10 jointly wind up a cable 30, and similarly, the above-mentioned two second winding assemblies 20 also jointly wind up a cable 30. When the photovoltaic component 2 is inspected, the two first winding assemblies 10 rotate in two opposite directions respectively, and similarly, the two second winding assemblies 20 rotate in two opposite directions respectively, so that the two cables 30 are tightened. When the two cables 30 are tightened, the cleaning assembly 50 can move stably on the two cables 30, thereby stably cleaning the dirt on the surface of the photovoltaic component 2. After cleaning an area, the detection assembly 60 is controlled to inspect the photovoltaic component 2.

[0024] After completing the inspection of an area of ​​the photovoltaic component 2, when it is necessary to move to another area for inspection, 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 degree of the detection component 60 during the movement. When moving to the area that needs to be inspected, the cleaning component 50 and the detection component 60 can quickly restore to a stable state for inspection. Compared with inspection in an unstable state, this detection method has relatively high accuracy and the data is of reference significance.

[0025] The photovoltaic module 2 includes a pair of vertical frames 21, and the two vertical frames 21 are fixedly connected by two horizontal frames 22. Photovoltaic panels 23 are embedded and fixedly installed on the inner walls of the vertical frames 21 and the horizontal frames 22. The vertical frames 21 and the horizontal frames 22 can not only support and fix the photovoltaic panels 23, but also protect the edges of the photovoltaic panels 23 from damage.

[0026] The supporting device 1 includes an installation frame 11 fixedly installed on the back of the photovoltaic panel 23, a connecting piece 12 is clamped on the installation frame 11, a supporting column 13 is rotatably installed on the connecting piece 12, and the bottom of the supporting column 13 is threadedly connected to the ground. Since the connecting piece 12 and the supporting column 13 are rotatably connected, they are used to adjust the inclination angle of the photovoltaic panel 23.

[0027] The installation box 3 includes a box body 31, and a mounting groove 32 is provided on the box body 31. By providing the mounting groove 32, some parts can be installed in a hidden manner, which not only saves space but also protects the parts inside the mounting groove 32 and prolongs the service life of the equipment.

[0028] 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 turning point of the vertical frame 21 and the horizontal frame 22, the steering effect of the detection device can be achieved through the flipping action of the first flip plate 41 and the second flip plate 42 and the coordinated setting of the first power assembly 5, the second power assembly 7, the first moving assembly 6 and the second moving assembly 8.

[0029] The first power assembly 5 includes a first motor 51 fixedly mounted on the side wall of the first flip plate 41 , and an output end of the first motor 51 is fixedly connected to a first driving gear 52 .

[0030] The second power assembly 7 includes a second motor 71 fixedly mounted on the side wall of the second flip plate 42 , and an output end of the second motor 71 is fixedly connected to a second driving gear 72 .

[0031] The first moving assembly 6 includes a first transmission shaft 62 that passes through and is rotatably installed at one end of the first flip plate 41 away from the second flip plate 42. A first driven gear 53 is fixedly sleeved on the outer peripheral wall of the first transmission shaft 62. The first driving gear 52 and the first driven gear 53 are meshedly connected. First moving wheels 61 are fixedly installed at both ends of the first transmission shaft 62. The first motor 51 can drive the first moving wheel 61 to rotate through the first driving gear 52, the first driven gear 53 and the first transmission shaft 62.

[0032] The second moving assembly 8 includes a second transmission shaft 82 that is rotatably installed on the end of the second flip plate 42 away from the first flip plate 41. A second driven gear 73 is fixedly sleeved on the outer peripheral wall of the second transmission shaft 82. The second driving gear 72 is meshingly connected with the second driven gear 73. Second moving wheels 81 are fixedly installed at both ends of the second transmission shaft 82. The second motor 71 can drive the second moving wheel 81 to rotate through the second driving gear 72, the second driven gear 73 and the second transmission 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.

[0033] The second movable wheel 81 includes a wheel body 811 fixedly installed at both ends of the second transmission shaft 82, and a plurality of 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 plurality of electric telescopic columns 812 are commonly fixedly connected with a pressure plate 813, and the pressure plate 813 is slidably set 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 structure and connection method of the first movable wheel 61 and the second movable wheel 81 are consistent.

[0034] The first transmission shaft 62 and the second moving wheel 81 are placed at the edge of the vertical frame 21 or the horizontal frame 22, and then the electric telescopic column 812 is started to drive the pressure plate 813 to extend toward the outside of the wheel body 811. When the pressure plates 813 on both sides are extended synchronously, pressure is applied to the outer walls on both sides of the vertical frame 21 or the horizontal frame 22, so as to achieve a clamping effect on the vertical frame 21 or the horizontal frame 22. Under the action of the friction force between the pressure plate 813 and the side wall 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, and will not When the detection device needs to be removed, it is only necessary to start the electric telescopic column 812 to drive the pressure plate 813 to retract toward the inside of 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 the horizontal frame 22 is cancelled, and the detection device can slide down from the edge of the vertical frame 21 or the horizontal frame 22. The above-mentioned setting can 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, and has strong applicability.

[0035] The traction assembly 70 includes a pair of bases 701 fixedly mounted on the inner wall of the inner cavity of the mounting groove 32, and third motors 702 are fixedly mounted on the two bases 701 respectively. The two third motors 702 are connected to the first flip plate 41 and the second flip plate 42 respectively through traction ropes 703.

[0036] The first winding assembly 10 includes a first winding motor 101 embedded and fixedly installed on the side wall of the box body 31 . The output end of the first winding motor 101 is fixedly connected to a first winding drum 102 , and the first winding drum 102 is wound with a cable 30 .

[0037] The second winding assembly 20 includes a second winding motor 201 embedded and fixedly installed on the side wall of the box body 31 , and an output end of the second winding motor 201 is fixedly connected to a second winding drum 202 , on which a cable 30 is wound.

[0038] Specifically, when the photovoltaic panel 23 is inspected, one of the installation boxes 3 is first attached to the edge of the horizontal frame 22. At this time, the electric telescopic column 812 is started to drive the pressure plate 813 to extend toward the outside of the wheel body 811. When the pressure plates 813 on both sides are extended synchronously, pressure is applied 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 consistent, 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 force between the pressure plate 813 and the side wall of the horizontal frame 22, one of the installation boxes 3 can be fixed at the edge of the horizontal frame 22, and the adsorption component 9 is started to generate negative pressure, so that the installation box 3 is firmly adsorbed on the outer wall of the horizontal frame 22.

[0039] Then, another installation box 3 is placed on the edge of the vertical frame 21. The same air-started electric telescopic column 812 drives the pressure plate 813 to extend toward the outside of the wheel body 811. When the pressure plates 813 on both sides are extended synchronously, pressure is applied 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 walls of the vertical frame 21, the other installation box 3 is fixed to the lower end of the vertical frame 21. The adsorption component 9 is also started to generate negative pressure, so that the installation box 3 is firmly adsorbed on the outer wall of the vertical frame 21; then the first motor 51 and the second motor 71 are started respectively to drive the first moving wheel 61 and the second moving wheel 81 to rotate on the vertical frame 21, so that the installation box 3 moves from the lower end of the vertical frame 21 to the upper end of the vertical frame 21.

[0040] When it moves to the turning point of the horizontal frame 22 and the vertical frame 21, the first motor 51 and the second motor 71 stop running. At this time, the first moving wheel 61 cancels the pressure applied to the outer walls of the two sides of the vertical frame 21, thereby losing the clamping effect on the vertical frame 21. Then, the third motor 702 connected to the first flip plate 41 through the traction rope 703 starts to run, and the traction rope 703 is relaxed. At this time, under the elastic force of the torsion spring 43, the first flip plate 41 will bring the first moving component 6 toward the top horizontal frame 2 2, until the first flip plate 41 is attached to the top wall of the vertical frame 21, so that the first moving wheel 61 resumes the pressure applied to the outer walls of both sides of the vertical frame 21, and clamps the side walls of the top horizontal frame 22 again. The suction component 9 on the outer wall of the first flip plate 41 generates negative pressure, so that the first flip plate 41 is firmly attached to the top wall of the vertical frame 21. Then, after closing the suction component 9 on the outer wall of the second flip plate 42, the electric telescopic column 812 is started to drive the pressure plate 813 toward the wheel body. 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 started to drive the pressure plate 813 to extend toward the outside of the wheel body 811. When the pressure plates 813 on both sides extend synchronously, pressure is applied to the outer walls on both sides of the top horizontal frame 21, thereby achieving a clamping effect on the top horizontal frame 22. After the adsorption component 9 on the outer wall of the second flip plate 42 is opened, the installation box 3 can be firmly adsorbed, thereby enabling the installation box 3 to move smoothly on the top horizontal frame 22.

[0041] When the two installation boxes 3 move to the stacking position, the two first winding motors 101 rotate in the opposite direction, driving the first winding drum 102 to rotate in the opposite direction to tighten the cable 30, and 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, tension will be generated between the two installation boxes 3, so that the two installation boxes 3 can move stably on the vertical frame 21 or the horizontal frame 22, which is beneficial to improve the stability of the detection device when moving. After the two cables 30 are fully tightened, the cleaning component 50 can drive the detection component 60 to move on the cable 30, and then perform a full-area detection of the photovoltaic panel 23. After the detection is completed, the device can be recovered by simply reversing the above steps.

[0042] Through the above-mentioned arrangement, when inspecting a large area of ​​photovoltaic panels 23, there is no need for personnel to move the device for inspection, and when the height of the photovoltaic panel 23 is high and personnel cannot touch it or it is inconvenient to install the inspection device, through this arrangement, it is possible to move from the bottom of the photovoltaic panel 23 to the top of the photovoltaic panel 23, and then perform mobile inspection. Such a arrangement not only saves manpower, but is also suitable for inspecting photovoltaic panels 23 of various installation heights and various installation forms, and has good applicability and flexibility. After use, the device can also be rolled up to reduce the size of the device for easy carrying and transportation.

[0043] In order to solve the technical problem that the infrared camera 606 shakes violently during the movement of the detection device, which is not conducive to capturing infrared light, such as Figure 1 - Figure 2 , Figure 4 - Figure 5 and Fig.12 - Fig.14 As shown, the following preferred technical solutions are provided: The stabilizing component 40 includes a mounting plate 401 fixedly mounted on the outer wall of the box body 31 , a telescopic rod 402 is fixedly mounted on the side wall of the mounting plate 401 facing the cleaning component 50 , and an electromagnet 403 is fixedly mounted on the output end of the telescopic rod 402 .

[0044] The cleaning assembly 50 includes a collecting box 501, which is provided with a pair of through slots 502. A plurality of pairs of driving wheels 503 are rotatably installed in the inner cavity of the through slots 502. The cable 30 passes through the gap between the two driving wheels 503. A permanent magnet 504 is fixedly installed on the side wall of the collecting box 501 facing the electromagnet 403. The permanent magnet 504 is aligned with the electromagnet 403. A plurality of vacuum cleaners 505 are connected and arranged on the side wall of the collecting box 501 facing the photovoltaic panel 23.

[0045] The detection component 60 includes a pair of electric push rods 601 fixedly installed on the outer wall of the collection box 501, and the output ends of the two electric push rods 601 are jointly fixedly installed with a support plate 602, and an anti-shake cloud platform 603 is fixedly installed on the outer wall of the support plate 602. The anti-shake cloud platform 603 has an anti-shake function, which is beneficial to improving the accuracy of shooting. The anti-shake principle of the anti-shake cloud platform 603 belongs to the prior art and will not be explained in detail here. A mounting frame 604 is rotatably installed on the upper end of the anti-shake cloud platform 603, and a clamping frame 605 is rotatably installed inside the mounting frame 604. An infrared camera 606 is clamped inside the clamping frame 605, and a servo motor 607 is fixedly installed on the side wall of the mounting frame 604. The output end of the servo motor 607 passes through the side wall of the mounting frame 604 and is fixedly connected to the clamping frame 605.

[0046] Specifically, before inspecting the photovoltaic panel 23, the driving wheel 503 drives the collection box 501 to move on the two cables 30. During the movement, the dust and impurities on the surface of the photovoltaic panel 23 are sucked into the interior of the collection box 501 by the vacuum cleaner 505 for collection. After cleaning an area, the electric push rod 601 is started to adjust the anti-shake cloud platform 603 and the infrared camera 606 to a suitable height, and then the servo motor 607 drives the clamping frame 605 and the infrared camera 606 to rotate inside the mounting frame 604, and the infrared camera 606 is adjusted to a suitable shooting angle for shooting. After the inspection of an area of ​​the photovoltaic panel 23 is completed, when it is necessary to move to another area for inspection, at this time, the telescopic rod 402 close to the collection box 501 is It starts to extend until the electromagnet 403 contacts the permanent magnet 504, then energizes the electromagnet 403 to generate attraction between the electromagnet 403 and the permanent magnet 504, fixes the cleaning component 50 as a whole, and reduces the shaking of the cleaning component 50 and the detection component 60 during movement. When moving to the area that needs to be detected, the cleaning component 50 and the detection component 60 can quickly restore to a stable state, thereby allowing the infrared camera 606 to quickly restore to a stable state to detect the photovoltaic panel 23. Compared with detection in an unstable state, this detection method has relatively high accuracy, and the data is of reference significance. After reaching the detection position, the permanent magnet 504 is powered off, and the telescopic rod 402 retracts to its original position to prevent affecting the normal operation of the cleaning component 50.
