[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] A photovoltaic device aging test equipment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a fixed structure is installed inside the housing 1. Inside the housing 1, there is a photovoltaic backsheet placement plate 17. Above the placement plate 17, there is a clamping rod 21 for holding the photovoltaic backsheet. One side of the clamping rod 21 and the top surface of the placement plate 17 have slots 18 for engaging the photovoltaic backsheet. Below the ultraviolet lamp 5, there is a circular box 13 that drives all the photovoltaic backsheets to rotate. The fixed structure also includes a moving groove 20, clamping rod 21, rack 22 and second gear 23. One side of the side box 19 is fixedly connected to one side of the placement plate 17, and the other side of the side box 19 is fixedly connected to the wall of the circular box 13. Next, two movable slots 20 are opened on one side of the side box 19. There are two movable slots 20. One end of each of the two clamping rods 21 is slidably connected to one movable slot 20. One end of each of the two clamping rods 21 is fixedly connected to one rack 22. The two racks 22 are fixedly connected to the same second gear 23. The second gear 23 is rotatably connected to one side of the cavity of the side box 19. There are several sets of fixed structures. Several bevel gears 15 are set inside the round box 13. Each bevel gear 15 is rotatably connected to the round box 13. The end of each bevel gear 15 extends into the side box 19 and is fixedly connected to one side of a second gear 23.

[0027] A uniformly sized photovoltaic backsheet is inserted into the slot 18 of the placement plate 17. The rotation of the bevel gear 15 drives the rotation of the second gear 23, which in turn drives the two racks 22 to move in an alternating manner. The two clamping rods 21 move closer to the center of the placement plate 17, clamping the photovoltaic backsheet on both sides. The photovoltaic backsheet is restricted to the ground and both sides in the slot 18. The two clamping rods 21 hold the photovoltaic backsheet in place, making it less likely for the photovoltaic backsheet to shake during rotation. This simulates natural conditions more closely and measures aging more accurately. The distance between the two clamping rods 21 can be adjusted, making it suitable for photovoltaic backsheets of different widths and thus more widely applicable.

[0028] A photovoltaic device aging test equipment, such as Figure 1 , Figure 2 and Figure 3As shown, a rotating circle 14 is provided in the middle of the bevel gear 16. The rotating circle 14 is rotatably connected to the bottom surface of the circular box 13. Several bevel gears 16 are fixedly provided on the top edge of the rotating circle 14.

The protective box 7 is fixedly provided on the inner bottom surface of the box body 1. The first gear 8 meshes with the third gear 24. The top surface of the first gear 8 is rotatably connected to the inner top surface of the protective box 7. The bottom end of the first gear 8 is rotatably connected to the bottom surface of the box body 1. The top surface of the third gear 24 is fixedly connected to one end of the outer cylinder 11. The other end of the outer cylinder 11 extends outward. The protective box 7 is fixedly connected to the bottom surface of the round box 13. One end of the sleeve rod 10 passes through the outer cylinder 11 and the third gear 24 and is rotatably connected to the outer cylinder 11 and the third gear 24. The other end of the sleeve rod 10 passes through the protective box 7 and the round box 13 and is finally fixedly connected to the bottom surface of the rotating round box 14. The sleeve rod 10 is rotatably connected to both the round box 13 and the protective box 7. A connecting rod 9 is provided below the third gear 24. The other end of the sleeve rod 10 extends into the cavity of the connecting rod 9 and is rotatably connected to the connecting rod 9. A pin is provided on the wall of the connecting rod 9. Several insertion holes are opened on the wall of the connecting rod 9 and the wall of the sleeve rod 10. The pin is inserted into the insertion holes. The other end of the connecting rod 9 is rotatably connected to the bottom surface of the box 1.

[0029] The connecting rod 9 rotates, causing the sleeve rod 10 to rotate inside the outer cylinder 11. The rotating circle 14 rotates accordingly, as does the bevel gear 16. All the bevel gears 15 rotate, clamping the photovoltaic backsheet. The protective box 7 has a door on one side. Opening the door and removing the pin separates the connecting rod 9 from the sleeve rod 10. The first gear 8 rotates, causing the third gear 24 to rotate. The outer cylinder 11 rotates accordingly, causing the round box 13, bevel gears 15, bevel gears 16, and side box 19 to rotate. The clamped photovoltaic backsheet rotates around the ultraviolet lamp 5.

[0030] A photovoltaic device aging test equipment, such as Figure 1 , Figure 2 and Figure 3 As shown, the housing 1 is positioned above the ground. Inside the housing 1 are an ultraviolet lamp 5 and a heating wire 6. A first servo motor 3 and a second servo motor 4 are fixedly mounted on the bottom surface of the housing 1 via a bracket. The rotating shaft of the first servo motor 3 is fixedly connected to the bottom end of the first gear 8, and the rotating shaft of the second servo motor 4 is fixedly connected to one end of a connecting rod 9.

[0031] Turn on the power to the second servo motor 4. The second servo motor 4 is a forward and reverse servo motor. The rotating shaft of the second servo motor 4 drives the connecting rod 9 to rotate. Turn on the power to the first servo motor 3. The rotating shaft of the first servo motor 3 drives the first gear 8 to rotate. The chamber 1 is also equipped with a temperature sensor, a humidity sensor, and an atomizing nozzle. The chamber is equipped with a PLC controller. It is worth noting that the PLC controller, temperature sensor, humidity sensor, atomizing nozzle, ultraviolet lamp 5, and heating wire 6 are all existing technologies and have been disclosed in CN202320451384.3, a test device for the anti-aging ability of photovoltaic backsheets. The specific implementation method will not be described in detail here. The humidity sensor detects the air humidity inside the chamber. If the humidity is low, the PLC controller controls the atomizing nozzle to turn on and inject water vapor into the chamber to make the humidity reach the test requirements. The ultraviolet lamp is turned on. At the same time, the temperature sensor detects the temperature inside the chamber. If the temperature is too low, the PLC controller controls the heating wire to turn on the power to heat the air inside the chamber, thereby controlling the temperature inside the chamber within the test requirements.

[0032] The working principle of this utility model is as follows: A photovoltaic backsheet of uniform size is inserted into the slot 18 of the placement plate 17. The power of the second servo motor 4 is turned on. The second servo motor 4 is a forward and reverse servo motor. The rotating shaft of the second servo motor 4 drives the connecting rod 9 to rotate. The power of the first servo motor 3 is turned on. The rotating shaft of the first servo motor 3 drives the first gear 8 to rotate. The rotation of the connecting rod 9 drives the sleeve rod 10 to rotate inside the outer cylinder 11. The rotating circle 14 rotates accordingly. The bevel gear 16 rotates accordingly. All bevel gears 15 rotate. The rotation of the bevel gears 15 drives the second gear 23 to rotate. The second gear 23 drives the two racks 22 to move alternately. The two clamping rods 21 move closer to the center of the placement plate 17, thus directing the light... The photovoltaic back panel is clamped on both sides, and the ground and both sides of the photovoltaic back panel are restricted in the slot 18. Two clamping rods 21 hold the photovoltaic back panel in place, so the photovoltaic back panel is not easy to shake when rotating. The simulated natural conditions are closer, and the measurement of aging is more accurate. The size of the two clamping rods 21 can be adjusted to suit photovoltaic back panels of different widths, making it more versatile. The photovoltaic back panel is clamped, and a door is provided on one side of the protective box 7. Open the door, pull out the pin, and the connecting rod 9 separates from the sleeve rod 10. The first gear 8 rotates, driving the third gear 24 to rotate. The outer cylinder 11 rotates accordingly, driving the round box 13, bevel gear 15, bevel tooth 16 and side box 19 to rotate. The clamped photovoltaic back panel rotates around the ultraviolet lamp 5.
