When the solar photovoltaic panels are placed horizontally, they can be slightly adsorbed to avoid the position of the solar photovoltaic panels shifting due to vibration generated when the test device starts. Before the support plate drives the solar photovoltaic panels to tilt, the adsorption force on the solar photovoltaic panels can be increased first. The integration of adsorption and adjustment enables the staff to complete the angle adjustment of the solar photovoltaic panels by simply driving the turntable, making the control of the tilt angle of the solar photovoltaic panels more accurate, making the irradiation angle of the simulated sunlight radiation more accurate, making the test data more referenceable. At the same time, as the tilt angle of the support plate increases, the adsorption force also gradually increases. Meanwhile, during the bidirectional switching of the tilt angle of the support plate, the solar photovoltaic panels can be prevented from being impacted by the gas backflow inside the folding suction cups, avoiding the position of the solar photovoltaic panels from shifting and ensuring the accuracy of the test data.

Detailed implementation manners

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the drawings in the specification.

[0028] Referring to Figures 1 to 8 , this technical solution provides a test mechanism, an adsorption mechanism, and an adjusting mechanism for a test device for simulating sunlight radiation, which can test a solar photovoltaic panel, integrally control the solar photovoltaic panel, and perform two-way adjustment of the inclination angle of the solar photovoltaic panel, and can adsorb the solar photovoltaic panel before adjusting its angle.

[0029] Furthermore, the test mechanism can irradiate the solar photovoltaic panel inside the box body 10 to test various data of the solar photovoltaic panel. It includes the box body 10, and an observation window is also provided on the box body 10. An absorbing plate is covered at the observation window, and the absorbing plate can prevent the light source of the irradiation lamp 11 from refracting. The irradiation lamp 11 is arranged on the top surface inside the box body 10. The irradiation lamp 11 is a light source of different brands and models (such as xenon lamp) for irradiating the surface of the solar photovoltaic panel for testing. The box body 10 is provided with an internal groove 12 and a slot 13, and the groove 12 and the slot 13 communicate with each other. The support part 14 is arranged inside the slot 13.

[0030] Further, the support part 14 includes a long rod 141 inside the slot 13. The long rod 141 can move horizontally inside the slot 13. One end of the long rod 141 extends to the outside of the box body 10. A U-shaped block 142 is arranged on the side wall of the long rod 141, and a support plate 143 is connected to the U-shaped block 142.

[0031] It should be noted that the number of U-shaped blocks 142 is four. The four U-shaped blocks 142 are evenly distributed at the bottom of the support plate 143, and the four U-shaped blocks 142 are respectively in contact with the inner wall of the groove 12. Through the arrangement of the long rod 141 and the U-shaped block 142, the position of the support plate 143 can be limited.

[0032] During use, after the position of the solar photovoltaic panel is fixed, the support plate 143 can be flipped around one of the long rods 141, so that the two U-shaped blocks 142 are separated from the long rod 141, so as to adjust the inclination angle of the solar photovoltaic panel located on the support plate 143.

[0033] Further, the adsorption mechanism can adsorb and fix the solar photovoltaic panel placed on the support plate 143 to prevent the solar photovoltaic panel from slipping when the support plate 143 is tilted. It includes a through hole 20 on the support part 14 and a driving part 21. The through hole 20 is arranged at the center position of the support plate 143. A fixing ring 22 is arranged inside the through hole 20. An adsorption part 23 is arranged on the fixing ring 22. An air extraction part 24 is arranged on the adsorption part 23. A buffer part 25 is arranged on the driving part 21.

[0034] Further, the driving part 21 includes a turntable 211 at one end of the long rod 141. A dial rod is arranged on the turntable 211. A clamping rod 212 is installed outside the box body 10. The clamping rod 212 is in a "T" shape. When the clamping rod 212 is clamped with the turntable 211, the staff can pull the protruding part of the clamping rod 212 to separate the turntable 211 from the clamping rod 212. An annular groove 213 is formed on the side wall of the long rod 141. A slider 214 is arranged inside the groove 12. The slider 214 is sleeved on the side wall of the long rod 141. A short block 215 is installed on the inner wall of the slider 214. The short block 215 is located inside the annular groove 213.

[0035] During use, when the long rod 141 moves horizontally inside the slot 13, the long rod 141 can drive the short block 215 located inside the annular groove 213 to move together. The short block 215 drives the slider 214 to move inside the groove 12. When the long rod 141 rotates, the short block 215 is not affected by the long rod 141.

[0036] Further, the adsorption part 23 includes a short tube 231 on the fixing ring 22. The short tube 231 is fixedly arranged on the inner wall of the fixing ring 22. A folding suction cup 232 is connected to the top of the short tube 231.

[0037] It should be noted that when there is no solar photovoltaic panel on the top of the support plate 143, the top of the folding suction cup 232 protrudes through the through hole 20. When the solar photovoltaic panel is placed on the support plate 143, the solar photovoltaic panel can squeeze the folding suction cup 232 to discharge part of the gas inside the folding suction cup 232, slightly adsorb the solar photovoltaic panel, which is convenient for the staff to take, and at the same time, it can prevent the position of the solar photovoltaic panel from shifting due to the slight vibration generated by the staff in the box body 10.

[0038] Furthermore, the air extraction part 24 includes a cross tube 241 on the side wall of the short tube 231. The number of the cross tubes 241 is two, and the two cross tubes 241 are respectively located on both sides of the short tube 231. A limiting ring 242 is fixedly connected to the inner wall of the cross tube 241, and the limiting ring 242 is located on the side adjacent to the short tube 231. A first piston 243 is arranged inside the cross tube 241. Both ends of the first piston 243 are respectively connected with a pull rope 244 and a first spring 245. The end of the pull rope 244 far away from the first piston 243 extends to the outside of the cross tube 241 and is connected with the slider 214.

[0039] Furthermore, both ends of the first spring 245 are respectively connected with the first piston 243, so that the side wall of the short tube 231 is in a sealed state.

[0040] During use, when one of the pull ropes 244 is pulled, the pull rope 244 can drive the first piston 243 to move inside the cross tube 241, so that the air inside the folding suction cup 232 and the short tube 231 moves into the cross tube 241, increasing the adsorption force on the solar photovoltaic panel and making the fixation of the solar photovoltaic panel more firm. At the same time, in order to prevent the air inside the other cross tube 241 from entering the short tube 231 and reducing the adsorption force on the solar photovoltaic panel, while the first piston 243 drives the first spring 245 to elongate, the first spring 245 can drive the other first piston 243 to tightly stick to the limiting ring 242.

[0041] Furthermore, the buffer part 25 includes a fixing plate 251 inside the groove 12. One side of the fixing plate 251 far away from the slider 214 is connected with a buffer tube 252. One side of the fixing plate 251 adjacent to the slider 214 is connected with a second spring 253, and the second spring 253 is connected with the slider 214. A tapered tube 254 is arranged on the side wall of the buffer tube 252, and the tapered tube 254 is located on the side adjacent to the fixing plate 251. The tapered opening of the tapered tube 254 faces the inside of the buffer tube 252. A push rod 255 is connected to the slider 214, and one end of the push rod 255 is connected with a second piston 256, and the second piston 256 is located inside the buffer tube 252.

[0042] During use, when the long rod 141 drives the slider 214 to move, the slider 214 drives the pulling rope 244, causing the pulling rope 244 to drive the first piston 243 to move inside the horizontal tube 241, completing the adsorption of the solar photovoltaic panel. At the same time, the slider 214 drives the push rod 255, and the push rod 255 drives the second piston 256 to move inside the buffer tube 252. During the movement of the second piston 256, external air can be inhaled into the buffer tube 252 through the tapered tube 254. When the slider 214 moves, it squeezes the second spring 253, causing the second spring 253 to contract. When the long rod 141 drives the turntable 211 to complete the engagement with the clamping rod 212, the relative positions of the slider 214 and the fixed plate 251 do not change.

[0043] Furthermore, the adjusting mechanism can adjust the inclination angle of the support plate 143 to make the test data of the solar photovoltaic panel more accurate, including the adjusting part 30 and the placement groove 31 on the support part 14. The placement groove 31 is located at the bottom of the support plate 143, and a follower part 32 is arranged inside the placement groove 31.

[0044] Even further, the adjusting part 30 includes a first thread 301 on the long rod 141. The first thread 301 is located between the U-shaped block 142 and the fixed plate 251. A push block 302 is arranged on the side wall of the long rod 141. The push block 302 can slide inside the groove 12. The top of the push block 302 is connected with a rotating column 303. The rotating column 303 can rotate on the top of the push block 302. The push block 302 is slidably connected with the bottom surface inside the groove 12.

[0045] During use, when the staff presses the turntable 211, the turntable 211 can drive the long rod 141 to move into the slot 13. When the turntable 211 engages with the clamping rod 212, the long rod 141 drives the first thread 301 to contact the push block 302. At this time, when the staff drives the turntable 211, the turntable 211 drives the long rod 141 to rotate, and the long rod 141 drives the push block 302 to move on the first thread 301.

[0046] Even further, the follower part 32 includes a sliding rod 321 inside the placement groove 31. A ring 322 is sleeved on the side wall of the sliding rod 321. The ring 322 is rotatably connected with the side wall of the sliding rod 321, enabling the ring 322 to rotate on the side wall of the sliding rod 321. A strip-shaped plate 323 is connected to the side wall of the ring 322 through a hinge. One end of the strip-shaped plate 323 away from the ring 322 is connected to the rotating column 303 through a hinge. The strip-shaped plate 323 is inclined.

[0047] In use, when the push block 302 moves on the side wall of the long rod 141 and approaches the fixed plate 251, the push block 302 can squeeze the strip plate 323, causing one end of the strip plate 323 to flip around the ring 322 and the other end of the strip plate 323 to flip around the rotating column 303. The strip plate 323 lifts the ring 322, the ring 322 drives the slide rod 321, the slide rod 321 drives the support plate 143 to rise, and the support plate 143 drives the U-shaped block 142 to flip around the long rod 141. When the support plate 143 rises, it will drive the slide rod 321 to approach the middle position of the box body 10. Therefore, the slide rod 321 can drive the ring 322, the ring 322 drives the strip plate 323, and the strip plate 323 drives the rotating column 303 to rotate, causing the strip plate 323 to flip and rotate at the same time, so that the support plate 143 can be tilted at a greater angle. When the support plate 143 flips, the inner wall of the placement groove 31 does not contact the strip plate 323.

[0048] Working principle: When it is necessary to test the newly produced solar photovoltaic panel, the staff places the solar photovoltaic panel inside the box body 10 of the testing equipment, so that the solar photovoltaic panel is located above the through hole 20. Due to the certain weight of the solar photovoltaic panel itself, the solar photovoltaic panel can squeeze the folding suction cup 232, causing some of the gas inside the folding suction cup 232 to be squeezed out, and the self-restoring force of the folding suction cup 232 gives the solar photovoltaic panel some suction force, avoiding the position of the solar photovoltaic panel from shifting due to the vibration of the testing equipment itself when it starts. Then, the irradiation lamp 11 is started to test the solar photovoltaic panel.

[0049] To ensure the accuracy of the test, it is necessary to test solar photovoltaic panels at different angles. A data acquisition and processing system is used to monitor and record various data during the test in real time, including radiation intensity, temperature, humidity, performance parameters of the sample, etc. At the same time, observe the appearance changes of the sample, such as color, gloss, cracks, etc., and record the relevant data. When testing, the staff only needs to press the turntable 211 outside the box body 10, so that the turntable 211 drives the long rod 141 to move into the slot 13, and can adsorb the solar photovoltaic panel on the support plate 143, avoiding the position deviation of the solar photovoltaic panel caused by the vibration generated during the operation of the test device or the sliding and deviation of the solar photovoltaic panel when the support plate 143 is tilted, which affects the accuracy of the test data. During this process, the long rod 141 drives the slider 214 to move inside the groove 12, and the long rod 141 drives the first thread 301 to approach the push block 302. When the slider 214 moves, it drives the push rod 255 and the pull rope 244, and the pull rope 244 drives the first piston 243 to separate from the limit ring 242, so as to increase the adsorption force on the solar photovoltaic panel. At the same time, when the first spring 245 elongates, it increases the pulling force on another first piston 243, preventing new gas from entering the inside of the short tube 231, ensuring the stability of adsorption, reducing the time used for adsorption at the same time, ensuring that the equipment quickly enters the test link, and improving work efficiency. The push rod 255 drives the second piston 256 to move inside the buffer tube 252, and fills the inside of the buffer tube 252 with gas. When the slider 214 moves, it squeezes the second spring 253. After the clamping rod 212 buckles the turntable 211, the first thread 301 contacts the push block 302. After the adsorption of the solar photovoltaic panel is completed, the angle adjustment link of the solar photovoltaic panel can be entered. The work process is smoothly connected, simplifying the work process, achieving immediate stop when turning to adjust the angle of the solar photovoltaic panel, making the adjustment of the angle of the solar photovoltaic panel more accurate. The staff drives the lever, the lever drives the turntable 211 to rotate, the turntable 211 drives the long rod 141 to rotate, so that the push block 302 moves on the first thread 301, so that the push block 302 can drive the rotating column 303 to move. By squeezing the strip plate 323 through the rotating column 303, the strip plate 323 lifts the ring 322, and the strip plate 323 can drive the rotating column 303 to rotate while lifting. Compared with the vertical flipping support method in the prior art, this method can lift the support plate 143 to a larger angle, facilitating the test device to collect more comprehensive data, making the judgment of the solar photovoltaic panel by the staff more accurate when analyzing the data. The ring 322 drives the slide bar 321, and the slide bar 321 drives the support plate 143 to flip, and the support plate 143 drives the solar photovoltaic panel to tilt. As the support plate 143 tilts, the horizontal tube 241 can further squeeze the pull rope 244, so that the pull rope 244 pulls the first piston 243, further enhancing the adsorption force. As the tilt angle of the support plate 143 increases, the supporting force of the support plate 143 itself on the solar photovoltaic panel will decrease.As the adsorption force increases, the possibility of the solar photovoltaic panel falling off the support plate 143 during the test of the test device is avoided, ensuring the stable progress of the test process.

[0050] When it is necessary to test the data when the other side of the solar photovoltaic is tilted, the staff reversely drives the lever, and the lever drives the turntable 211 to rotate reversely, so that the push block 302 disengages from the first thread 301, and the support plate 143 returns to the horizontal position, facilitating the support plate 143 to drive the solar photovoltaic panel to tilt to the other side to test and collect new data. The more data is collected, the more accurate the staff's judgment of the solar photovoltaic panel is. The staff presses the clamping rod 212 to disengage the clamping rod 212 from the turntable 211. At this time, under the restoration of the first spring 245 and the second spring 253, the second spring 253 drives the slider 214 to move, and the slider 214 drives the long rod 141 and the push rod 255 to move together. The push rod 255 drives the second piston 256 to squeeze the gas inside the buffer tube 252. Through the setting of the conical tube 254, the gas slowly discharges from the conical tube 254, slowing down the restoration speed of the second spring 253 and reducing the moving speed of the long rod 141, so that the speed of the slider 214 is also reduced, thereby reducing the flow rate of the gas inside the horizontal tube and avoiding the gas impact on the solar photovoltaic panel caused by the rapid restoration of the first spring 245 driving the first piston 243, which may cause the position of the solar photovoltaic panel to shift and affect the accuracy of the test data. When the second spring 253 and the first spring 245 return to the initial state, the staff drives another lever to turn up the support plate 143 from the other side, so that the support plate 143 is at multiple tilt angles, and the test device tests the solar photovoltaic panel on the support plate 143 to collect more test data for the staff to refer to. After the test, the sample is inspected in detail, and the changes in its appearance, color, performance, etc. are recorded and compared with the initial state to evaluate the performance change and aging degree of the sample under sunlight radiation. The data collected during the test is sorted and analyzed to evaluate the performance stability and durability of the sample under sunlight radiation. According to the test data and results, a detailed test report is compiled.
