Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module stability detection. Specifically, it relates to a high-stability test system and method for photovoltaic modules. Background Art

[0002] Photovoltaic equipment is a new energy device that converts solar energy into electrical energy. Through light irradiation, a solar panel is used for photovoltaic conversion. When detecting the current and voltage of a photovoltaic module through a current-voltage detector, its actual power generation capacity can be evaluated, or its temperature characteristics can be tested to understand the performance of the photovoltaic module at different temperatures and evaluate the adaptability of the photovoltaic module under different environmental conditions. By simulating the actual use conditions in different environments, the durability and reliability of the photovoltaic module can be evaluated. During the use of a photovoltaic panel, due to different lighting conditions, the surface of the solar panel is heated and changed, resulting in a change in the conversion efficiency of solar energy. Therefore, it is necessary to test its heat resistance.

[0003] After retrieval, the existing patent (Publication No.: CN116505877B) discloses a heat resistance test assembly for a photovoltaic module, which includes a support assembly, a monitoring assembly, a fixing assembly, a lighting assembly, an electric control assembly, and a control assembly; the support assembly includes multiple groups of first support columns, and an air storage bellows is arranged on the outer surface of the first support column, and a connecting hose is communicated with the bottom of the air storage bellows; this device has good adaptability. It can not only accurately position the solar panel to improve the uniformity and thoroughness of the power generation and heat generation of the solar panel, but also can adaptively adjust the position of the solar panel when a certain lamp head is damaged, improving the stability and accuracy of the photovoltaic power generation of the solar panel.

[0004] However, there are still certain deficiencies in the above solution. It can only perform detection work on a single photovoltaic panel each time. And after the photovoltaic panel is subjected to high-temperature detection, due to the high temperatures of the photovoltaic panel and the components of the installation plate, it is not convenient for the staff to disassemble and replace the photovoltaic panel to be tested, resulting in low safety and practicability. At the same time, since it can only perform detection work on the photovoltaic panel in a high-temperature state, it is not conducive to replacing the photovoltaic panel to be tested, and also reduces the applicability of the device and cannot perform performance detection on the photovoltaic panel in a low-temperature state at the same time.

[0005] In view of this, the present invention proposes a high-stability test system and method for photovoltaic modules. Summary of the Invention

[0012] Preferably, the partition plate is in a T shape. Two through grooves are symmetrically opened on the partition plate. The two link rods are respectively hinged inside the two through grooves.

[0013] Preferably, the second detection platform includes a second detection table. Columns are fixedly connected to the bottoms of the four corners of the second detection table. A translation frame is arranged below the second detection table. Sleeves are fixedly penetrated and arranged inside the four corners of the translation frame. The columns slide through the inside of the sleeves. The four columns are divided into two groups in pairs. A bottom plate is jointly fixedly connected to the bottom ends of each group of columns. A connecting shaft is fixedly connected to the outer wall of the bottom plate. A roller is rotatably connected to the end of the connecting shaft away from the bottom plate. The roller is slidably sleeved inside the guiding groove.

[0014] Preferably, the driving components on the driving mechanism include two sprockets and a chain meshing between the two sprockets. The sprockets are rotatably connected to the side plates. The driving motor is fixedly installed on the outer wall of the outer box. The output shaft on the driving motor rotatably penetrates through the outer wall of the outer box and is fixedly connected to one of the sprockets;

[0015] The driving mechanism further includes four connecting pieces. One end of each connecting piece is fixedly connected with a connecting rod. The four connecting pieces are divided into two groups, which are respectively located on the upper and lower sides of the chain. The connecting rods located on the upper and lower sides are fixedly connected to the fixed strip and the translation frame respectively.

[0016] Preferably, the first guiding mechanism includes two T-shaped supporting rods fixedly connected to the bottom of the outer box. Two T-shaped frames are fixedly connected between the two T-shaped supporting rods. The T-shaped frames extend into the translation frame and are slidably connected thereto.

[0017] Preferably, the air-cooling assembly includes an air duct fixedly penetrating through the top of the outer box. The bottom end of the air duct is fixedly communicated with a hollow frame.

[0018] Preferably, the temperature-raising assembly includes a mounting plate. An electric heating rod is installed at the bottom of the mounting plate. The top end of the mounting plate is rotatably connected with a lead screw. The lead screw threadedly penetrates through the top of the outer box. The top end of the lead screw is fixedly connected with a turntable. A vertical shaft is fixedly connected to the top end of the mounting plate. The vertical shaft slidably penetrates through the top of the outer box.

[0019] A high-stability test method for a photovoltaic module, using the high-stability test system for the photovoltaic module as described above, includes the following steps:

[0020] S1. Initially, the second detection platform is located near the box door side, the temperature-raising assembly is located above the first detection platform, and the air-cooling assembly is located above the second detection platform. During operation, the photovoltaic module to be detected is placed on the second detection platform. Then, the driving motor is started. The driving motor drives the sprocket to rotate clockwise through its output shaft, so that the chain drives clockwise. During the clockwise transmission of the chain, the two connecting pieces located on the lower side drive the bottom plate to move leftward. On the contrary, the two connecting pieces located on the upper side drive the first detection platform to move rightward through the fixed strip, that is, the first detection platform and the second detection platform can move in opposite directions;

[0021] S2. During the process of the bottom plate moving to the left, the bottom plate drives the roller to slide on the inner side of the guide groove through the connecting shaft, so that the bottom plate moves in the process of translation, downward movement, translation, upward movement, and translation. During this process, the bottom plate can drive the second detection platform to move up and down through the column, and the first detection platform is always in a state of equal height translation under the guide limit of the slide seat and the guide rod. This makes it possible for the second detection platform to pass from the lower side of the first detection platform when the second detection platform moves in the opposite direction to the first detection platform, so that the second detection platform and the first detection platform slide staggered and the second detection platform and the first detection platform are interchanged.

[0022] S3. Then, the power is turned on and the electric heating rod is turned on. The electric heating rod heats the photovoltaic module on the second test platform below it, so that the temperature of the photovoltaic module gradually increases, thereby testing the heat resistance performance of the photovoltaic module under high temperature. At this time, the first test platform is located below the air-cooled component. At this time, the second photovoltaic module to be tested can be installed on the first test platform and wait for the next high temperature resistance test.

[0023] S4. After the high-temperature resistance test of the first photovoltaic component is completed, the driving motor drives the sprocket to reverse through its output shaft, causing the chain to rotate counterclockwise, so that the second test platform and the first test platform are swapped again and return to the initial position. At this time, the second photovoltaic component to be tested on the first test platform is located under the heating component and is heated to a high temperature by the heating component, while the first photovoltaic component returns to the bottom of the air-cooling component with the second test platform. At this time, the first photovoltaic component in a high-temperature state is not convenient to disassemble, and the setting of the air-cooling component can connect the air duct with the external air conditioner, and inject cold air into the inside of the hollow frame through the air conditioner and the air duct. The cold air inside the hollow frame is discharged through the blower pipe to cool down the first photovoltaic component on the second test platform. At this time, the cooled first photovoltaic component can be disassembled and the third photovoltaic component to be tested can be installed on the second test platform, or the first photovoltaic component can be continuously cooled to test the performance of the photovoltaic component in a low-temperature state;

[0024] S5. The setting of the partition can block the space corresponding to the cooling and heating inside the outer box to a certain extent, and in the process of movement of the first detection platform, the partition can be pushed and pulled by the connecting rod. In the process of the first detection platform and the second detection platform approaching each other, the connecting rod pushes up the partition, so that the partition does not block the translation of the first detection platform. In the process of the first detection platform and the second detection platform moving away from each other after crossing, the partition gradually moves down to block the space corresponding to the cooling and heating inside the outer box again.

[0025] The working principle and beneficial effects of the present invention are:

[0026] 1. In the present invention, two second guide mechanisms are symmetrically arranged inside the outer box, and a first inspection platform and a second inspection platform for placing the photovoltaic components to be tested are arranged between the two second guide mechanisms. A first guide mechanism is arranged between the two second guide mechanisms to support the second inspection platform in and out. A driving mechanism is arranged inside the outer box, and the driving mechanism includes a driving motor and two driving components. The two driving components are respectively located on one side of the second guide mechanism. While the driving motor drives the driving components, the driving components can be used to stagger the first inspection platform and the second inspection platform so that the first inspection platform and the second inspection platform can be interchanged. While a photovoltaic component is undergoing high-temperature testing, the next photovoltaic component can be pre-installed, thereby avoiding the time spent on disassembling photovoltaic panels under high temperature, significantly improving work efficiency, and improving safety performance.

[0027] 2. In the present invention, a partition is provided on the sliding sleeve at the top of the outer box. The partition can block the space corresponding to the cooling and heating inside the outer box to a certain extent, and the partition can be pushed and pulled by the connecting rod during the movement of the first detection platform. During the movement of the first detection platform and the second detection platform approaching each other, the connecting rod pushes up the partition so that the partition does not block the translation of the first detection platform. During the process of the first detection platform and the second detection platform moving away from each other after crossing, the partition gradually moves down to block the space corresponding to the cooling and heating inside the outer box again, thereby improving the stability of the detection environment.

[0028] 3. In the present invention, a heating component for heating the photovoltaic component to be tested and an air-cooling component for cooling the photovoltaic component to be tested are respectively provided in the spaces corresponding to the cooling and heating. The heating component and the air-cooling component correspond to the first detection platform and the second detection platform respectively. A photovoltaic component is heated at a high temperature by the heating component, and after the heating detection, the photovoltaic component is moved under the air-cooling component. At this time, the photovoltaic component in a high-temperature state is not convenient to be disassembled. The setting of the air-cooling component can connect the air duct with the external air conditioner, and inject cold air into the inside of the hollow frame through the air conditioner and the air duct. The cold air inside the hollow frame is discharged through the blower pipe to cool down the photovoltaic components on the second detection platform. At this time, the cooled photovoltaic components can be disassembled and other photovoltaic components to be tested can be installed on the detection platform. Alternatively, the photovoltaic components can be continuously cooled to detect the performance of the photovoltaic components in a low-temperature state, which has good applicability.

On the contrary, the two connecting members 24 located on the upper side drive the first detection platform 83 to move right through the fixing bar 81, that is, the first detection platform 83 and the second detection platform 91 can move in opposite directions.

[0057] Example 3

[0058] See also Figures 1-6, a high-stability test system and method for a photovoltaic module, including all the content of Embodiment 2. In addition, a partition plate 3 is slidably sleeved on the top of the outer box 1. The inner part of the outer box 1 is divided into two spaces by the partition plate 3. In the two spaces, a heating component 4 for heating the photovoltaic module to be tested and an air-cooling component 5 for cooling the photovoltaic module to be tested are respectively arranged.

[0059] Further, the partition plate 3 is in a T shape, and two through slots 31 are symmetrically formed on the partition plate 3. Two connecting rods 84 are respectively hinged to the inner sides of the two through slots 31.

[0060] Further, the air-cooling component 5 includes an air cylinder 51 fixedly penetrating through the top of the outer box 1. The bottom end of the air cylinder 51 is fixedly communicated with a hollow frame 52. The bottom of the hollow frame 52 is evenly distributed with air blowing pipes 53 communicated with the inside of the hollow frame 52.

[0061] Furthermore, the heating component 4 includes a mounting plate 45. An electric heating rod 44 is installed at the bottom of the mounting plate 45. The top end of the mounting plate 45 is rotatably connected to a lead screw 43. The lead screw 43 threadedly penetrates through the top of the outer box 1. The top end of the lead screw 43 is fixedly connected to a turntable 42. The top end of the mounting plate 45 is fixedly connected to a vertical shaft 41. The vertical shaft 41 slidably penetrates through the top of the outer box 1.

[0062] In this embodiment, by rotating the lead screw 43 through the turntable 42, the lead screw 43 can move up and down on the top of the outer box 1, thereby driving the mounting plate 45 to move up and down, so that the distance between the electric heating rod 44 arranged at the bottom of the mounting plate 45 and the photovoltaic module to be detected can be adjusted, and the temperature of the photovoltaic module is increased through the electric heating rod 44. The setting of the air-cooling component 5 can connect the air cylinder 51 with an external air conditioner, inject cold air into the inner side of the hollow frame 52 through the air conditioner and the air cylinder 51, and the cold air inside the hollow frame 52 is discharged through the air blowing pipes 53 to cool the first photovoltaic module on the second detection table 91.

[0063] Working principle and usage process: Initially, the second detection platform 9 is located close to the side of the box door 12. The heating component 4 is located above the first detection platform 8, and the air-cooling component 5 is located above the second detection platform 9. During operation, the photovoltaic module to be detected is placed on the second detection table 91. Then, the driving motor 21 is started. The driving motor 21 drives the sprocket 22 to rotate clockwise through its output shaft, so that the chain 23 is driven to rotate clockwise. During the clockwise rotation of the chain 23, the two connecting pieces 24 located on the lower side drive the bottom plate 95 to move leftward. On the contrary, the two connecting pieces 24 located on the upper side drive the first detection table 83 to move rightward through the fixing strip 81, that is, the first detection table 83 and the second detection table 91 can move in opposite directions.

[0064] During the process of the bottom plate 95 moving to the left, the bottom plate 95 drives the roller 97 to slide on the inner side of the guide groove 74 through the connecting shaft 96, so that the bottom plate 95 moves in a sequence of translation, downward movement, translation, upward movement, and translation. During this process, the bottom plate 95 can drive the second detection platform 91 to move up and down through the column 92, and the first detection platform 83 is always in a state of equal height translation under the guide limit of the slide 72 and the guide rod 73. This makes the second detection platform 91 pass from the lower side of the first detection platform 83 when the second detection platform 91 moves in the opposite direction to the first detection platform 83, so that the second detection platform 91 and the first detection platform 83 slide staggered and the second detection platform 91 and the first detection platform 83 are interchanged. Afterwards, when conducting a temperature characteristic test to understand the performance of the photovoltaic module at different temperatures, after placing the photovoltaic module on the test bench, electrically connect the data line on the current and voltage tester or other suitable testing equipment to the photovoltaic module to be tested, turn on the power, turn on the electric heating rod 44, and heat the photovoltaic module on the second test bench 91 located below it through the electric heating rod 44, so that the temperature of the photovoltaic module gradually increases, so as to detect the heat resistance of the photovoltaic module at high temperature. At this time, the first test bench 83 is located below the air-cooled component 5. At this time, the second photovoltaic module to be tested can be installed on the first test bench 83 and wait for the next high temperature resistance test.

[0065] After the high temperature resistance test of the first photovoltaic component is completed, the driving motor 21 drives the sprocket 22 to reverse through its output shaft, causing the chain 23 to rotate counterclockwise, so that the second test platform 91 and the first test platform 83 are swapped again and return to the initial position. At this time, the second photovoltaic component to be tested on the first test platform 83 is located below the heating component 4, and is heated to a high temperature by the heating component 4, while the first photovoltaic component returns to the bottom of the air cooling component 5 along with the second test platform 91. At this time, the first photovoltaic component in a high temperature state is not convenient to disassemble, and the setting of the air cooling component 5 can connect the air duct 51 to the external air conditioner, and inject cold air into the inside of the hollow frame 52 through the air conditioner and the air duct 51. The cold air inside the hollow frame 52 is discharged through the blower pipe 53 to cool down the first photovoltaic component on the second test platform 91. At this time, the cooled first photovoltaic component can be disassembled and the third photovoltaic component to be tested can be installed on the second test platform 91, or the first photovoltaic component can be continuously cooled to test the performance of the photovoltaic component in a low temperature state.

[0066] The arrangement of the partition plate 3 can block the spaces corresponding to the temperature reduction and increase inside the outer box 1 to a certain extent. During the movement of the first detection platform 83, the partition plate 3 can be pushed and pulled by the connecting rod 84. During the movement of the first detection platform 8 and the second detection platform 9 approaching each other, the connecting rod 84 pushes up the partition plate 3 so that the partition plate 3 does not block the translation of the first detection platform 83. During the process of the first detection platform 8 and the second detection platform 9 moving away from each other after staggering, the partition plate 3 gradually moves down to block the spaces corresponding to the temperature reduction and increase inside the outer box 1 again.

[0067] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.

10. A high resistance stability test method for a photovoltaic module, using the high resistance stability test system for a photovoltaic module according to any one of claims 1-9, characterized in that, Comprising the following steps: S1. Initially, the second inspection platform (9) is located on the side close to the box door (12), the heating component (4) is located above the first inspection platform (8), and the air cooling component (5) is located above the second inspection platform (9). During operation, the photovoltaic component to be inspected is placed on the second inspection platform (91). Then, the driving motor (21) is started. The driving motor (21) drives the sprocket (22) to rotate clockwise through its output shaft, so that the chain (23) is driven clockwise. During the clockwise transmission of the chain (23), the two connecting members (24) on the lower side drive the bottom plate (95) to move left. On the contrary, the two connecting members (24) on the upper side drive the first inspection platform (83) to move right through the fixing bar (81), that is, the first inspection platform (83) and the second inspection platform (91) can move in opposite directions. S2. During the process of the bottom plate (95) moving to the left, the bottom plate (95) drives the roller (97) to slide inside the guide groove (74) through the connecting shaft (96), so that the bottom plate (95) moves in the process of translation, downward movement, translation, upward movement, and translation. During this process, the bottom plate (95) can drive the second detection platform (91) to move up and down through the column (92), and the first detection platform (83) is always in the iso-high translation state under the guide limit of the slide (72) and the guide rod (73). This makes the second detection platform (91) pass through the lower side of the first detection platform (83) when it moves in the opposite direction to the first detection platform (83), so that the second detection platform (91) and the first detection platform (83) slide staggered and the second detection platform (91) and the first detection platform (83) are interchanged. S3. After that, the power is turned on and the electric heating rod (44) is turned on. The photovoltaic module on the second testing platform (91) located below the electric heating rod (44) is heated to gradually increase the temperature of the photovoltaic module, thereby testing the heat resistance of the photovoltaic module under high temperature. At this time, the first testing platform (83) is located below the air cooling component (5). At this time, the second photovoltaic module to be tested can be installed on the first testing platform (83) and wait for the next high temperature resistance test. S4. After the high-temperature resistance test of the first photovoltaic module is completed, the driving motor (21) drives the sprocket (22) to reverse through its output shaft, causing the chain (23) to rotate counterclockwise, so that the positions of the second detection table (91) and the first detection table (83) are swapped again and return to the initial position. At this time, the second photovoltaic module to be detected on the first detection table (83) is located below the heating component (4), and the heating component (4) is used to heat it at high temperature. The first photovoltaic module returns below the air-cooling component (5) with the second detection table (91). At this time, the first photovoltaic module in a high-temperature state is not easy to disassemble. The air-cooling component (5) is arranged such that the air duct (51) can be connected to an external air conditioner, and cold air is injected into the inside of the hollow frame (52) through the air conditioner and the air duct (51). The cold air inside the hollow frame (52) is discharged through the air blowing pipe (53) to cool the first photovoltaic module on the second detection table (91). At this time, the first photovoltaic module after cooling can be disassembled, and the third photovoltaic module to be detected can be installed on the second detection table (91), or the first photovoltaic module can be continuously cooled to detect the performance of the photovoltaic module in a low-temperature state. S5. The partition (3) is provided to block the spaces corresponding to cooling and heating inside the outer box (1) to a certain extent. During the movement of the first detection table (83), the partition (3) can be pushed and pulled through the connecting rod (84). During the movement of the first detection platform (8) and the second detection platform (9) approaching each other, the connecting rod (84) pushes up the partition (3) so that the partition (3) does not block the translation of the first detection table (83). During the process of the first detection platform (8) and the second detection platform (9) moving away from each other after staggering, the partition (3) gradually moves down to block the spaces corresponding to cooling and heating inside the outer box (1) again.
