Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically a test structure for photovoltaic power generation. Background Technology

[0002] Photovoltaic modules, also known as solar panels, are composed of solar cells or solar cells of different sizes cut by laser cutting machines or wire cutting machines. Since the current and voltage of a single solar cell are very small, they are first connected in series to obtain a high voltage, then connected in parallel to obtain a high current, which is then output through a diode. They are then encapsulated in a stainless steel, aluminum, or other non-metallic frame, fitted with a glass top and a backsheet, filled with nitrogen, and sealed. This entire assembly is called a module, or photovoltaic module, or solar cell module. Photovoltaic modules undergo power generation efficiency testing before leaving the factory.

[0003] A novel photovoltaic power generation testing device, disclosed in publication CN 221709809 U, includes a main housing and a moving component. The main housing has a storage slot on its inner bottom surface, within which a guide rod is installed. A clamping component is slidably connected to the guide rod. The clamping component comprises a support frame, a drive motor, a lead screw, a moving block, and a connecting block. The support frame is slidably connected to the guide rod. The drive motor is mounted on the support frame, and its output end extends into the support frame where a lead screw is installed. The lead screw is fitted with a moving block, and a connecting block is fixedly mounted on one side of the moving block. An upper clamping plate is mounted on the other end of the connecting block. This invention utilizes a protective component, employing Velcro-attached protective pads on the upper and lower clamping plates. This facilitates the replacement and disassembly of the protective pads, ensuring maintenance efficiency and preventing damage to the photovoltaic panels due to delayed replacement of worn protective pads.

[0004] However, the above-mentioned device still has some shortcomings in use. The position of the LED lighting is fixed, but in reality, the position of the sun is different at different times of the day, and the angle of illumination on the photovoltaic panel is also different. Therefore, it is impossible to simulate the illumination of the photovoltaic panel under different time periods and different sunlight angles, and the test is not accurate enough. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a test structure for photovoltaic power generation. It solves the problem that while the position of the LED lighting lamp remains fixed, the sun's position varies at different times of the day, resulting in different angles of illumination on the photovoltaic panel. Therefore, it is impossible to simulate the illumination of the photovoltaic panel under different time periods and angles of sunlight, leading to inaccurate testing.

[0006] This utility model provides the following technical solution: a photovoltaic power generation test structure, including a workbench, an arc-shaped bracket fixedly connected to the upper surface of the workbench, a connecting sleeve slidably installed on the arc-shaped bracket, a row of teeth fixedly connected to the upper surface of the arc-shaped bracket, a gear rotatably connected between the inner two side walls of the connecting sleeve, the gear meshing with the row of teeth, and an LED light board fixedly installed on the lower surface of the connecting sleeve.

[0007] The upper surface of the workbench has two grooves. A bidirectional screw is rotatably connected inside one of the grooves. Two threaded sleeves are threaded onto the surface of the bidirectional screw, and a clamp is fixedly connected to the top of each of the two threaded sleeves.

[0008] Preferred technical solution 1: A sliding rod is fixedly connected between the two inner side walls of the other groove, and two sliding sleeves are slidably sleeved on the surface of the sliding rod, and the two sliding sleeves are fixedly connected to the two clamping plates respectively.

[0009] Preferred technical solution 2: A first motor is fixedly connected to the side of the workbench, the output end of the first motor extends into the interior of one of the grooves and is fixedly connected to a first bevel gear, and a second bevel gear is fixedly sleeved on the surface of the bidirectional screw, and the first bevel gear and the second bevel gear mesh with each other.

[0010] Preferred technical solution three: A second motor is fixedly connected to the surface of the connecting sleeve, and the output end of the second motor passes through the connected connecting sleeve and is fixedly connected to the gear.

[0011] Preferred technical solution four: Both sides of the arc-shaped bracket are provided with sliding grooves, and sliders are slidably connected inside the two sliding grooves. Both sliders are fixedly connected to the connecting sleeve.

[0012] Preferred technical solution five: Protective pads are fixedly adhered to the surfaces of the two clamping plates and the upper surface of the workbench, and support columns are fixedly connected to the four corners of the lower surface of the workbench.

[0013] Compared with existing technologies, this utility model provides a photovoltaic power generation test structure with the following advantages: The method for testing the power generation efficiency of photovoltaic panels is already existing technology, so it will not be described in detail here. In use, the photovoltaic panel to be tested is placed on a workbench. Then, the rotation of the first motor drives the first bevel gear to rotate, which in turn drives the second bevel gear and the bidirectional screw to rotate. This causes the two screw sleeves and two clamping plates to clamp the photovoltaic panel. Simultaneously, the protective pads prevent excessive clamping force from damaging the photovoltaic panel. Once the photovoltaic panel is fixed, it can be illuminated by an LED light panel. During illumination, the rotation of the second motor drives the gears to rotate, causing the connecting sleeve and LED light panel to move along the arc-shaped support through the action of the teeth, thus simulating the solar radiation angle at different times to test the power generation efficiency of the photovoltaic panel. This test structure can clamp and fix different photovoltaic panels to maintain stability, and can simulate solar radiation conditions at different times to test the power generation efficiency of the photovoltaic panel.

Detailed Implementation

[0018] Please see Figure 1-3 ,

[0019] Example 1: A test structure for photovoltaic power generation includes a workbench 1, an arc-shaped support 2 fixedly connected to the upper surface of the workbench 1, a connecting sleeve 3 slidably installed on the arc-shaped support 2, a row of teeth 4 fixedly connected to the upper surface of the arc-shaped support 2, a gear 5 rotatably connected between the two inner side walls of the connecting sleeve 3, the gear 5 meshing with the row of teeth 4, and an LED light panel 6 fixedly installed on the lower surface of the connecting sleeve 3.

[0020] Two grooves 7 are formed on the upper surface of the workbench 1. A bidirectional screw 8 is rotatably connected inside one of the grooves 7. Two threaded sleeves 9 are threaded onto the surface of the bidirectional screw 8. A clamping plate 10 is fixedly connected to the top of each of the two threaded sleeves 9.

[0021] Example 2: The difference between this example and Example 1 is that a sliding rod 11 is fixedly connected between the two inner side walls of another groove 7. Two sliding sleeves 12 are slidably sleeved on the surface of the sliding rod 11. The two sliding sleeves 12 are fixedly connected to the two clamping plates 10 respectively. The movement of the clamping plates 10 is restricted by the sliding sleeves 12, which facilitates the clamping and fixing of the photovoltaic panel and keeps it stable.

[0022] Example 3: The difference between this example and Example 1 is that a first motor 13 is fixedly connected to the side of the workbench 1. The output end of the first motor 13 extends into the interior of one of the grooves 7 and is fixedly connected to a first bevel gear 19. A second bevel gear 20 is fixedly sleeved on the surface of the bidirectional screw 8. The first bevel gear 19 and the second bevel gear 20 mesh with each other. The rotation of the first motor 13 can automatically drive the two clamping plates 10 to clamp and fix the photovoltaic panel.

[0023] Example 4: The difference between this example and Example 1 is that a second motor 14 is fixedly connected to the surface of the connecting sleeve 3. The output end of the second motor 14 passes through the connected connecting sleeve 3 and is fixedly connected to the gear 5. The rotation of the second motor 14 can drive the gear 5 to rotate, thereby causing the connecting sleeve 3 and the LED light panel 6 to move along the arc-shaped bracket 2 to simulate sunlight at different times.

[0024] Example 5: The difference between this example and Example 1 is that the arc-shaped bracket 2 has grooves 15 on both sides, and sliders 16 are slidably connected inside the two grooves 15. The two sliders 16 are fixedly connected to the connecting sleeve 3, so that the movement of the connecting sleeve 3 is more stable and smooth.

[0025] Example 6: The difference between this example and Example 1 is that protective pads 17 are fixedly adhered to the surfaces of the two clamping plates 10 and the upper surface of the workbench 1, and support columns 18 are fixedly connected to the four corners of the lower surface of the workbench 1. The photovoltaic panels are protected by the protective pads 17 to prevent damage caused by excessive force.

[0026] In summary, the photovoltaic power generation test structure and the method for testing the power generation efficiency of photovoltaic panels are existing technologies, so they will not be described in detail here. During use, the photovoltaic panel to be tested is placed on the workbench 1. Then, the rotation of the first motor 13 drives the first bevel gear 19 to rotate, which in turn drives the second bevel gear 20 and the bidirectional screw 8 to rotate. This causes the two screw sleeves 9 and the two clamping plates 10 to clamp the photovoltaic panel. Simultaneously, the protective pad 17 prevents excessive clamping force from damaging the photovoltaic panel. Once the photovoltaic panel is fixed, it can be illuminated by the LED light panel 6. During illumination, the rotation of the second motor 14 drives the gear 5 to rotate, causing the connecting sleeve 3 and the LED light panel 6 to move along the arc-shaped support 2 through the action of the teeth 4, thus simulating the solar radiation angle at different times to test the power generation efficiency of the photovoltaic panel. This test structure can clamp and fix different photovoltaic panels to maintain stability, and can simulate solar radiation conditions at different times to test the power generation efficiency of the photovoltaic panel.
