[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention are described in detail.

[0019] The embodiment of the present invention provides a solar photovoltaic panel environment simulation system, such as Figure 1 and Figure 2As shown, it includes an environmental simulation module, an environmental control module and an electric control module.

The electric control module includes an electric control box 3, a refrigeration unit 31 and a humidity simulation unit 32 arranged in the electric control box 3, and a main control unit 33 arranged on the outer wall of the environmental simulation box 1. The humidity simulation unit 32 is connected to the natural wind simulation unit 21 through the air duct 24, the refrigeration unit 31 is connected to the natural wind simulation unit 21 through heat exchange, and the main control unit 33 is electrically connected to the natural wind simulation unit 21, the humidity simulation unit 32, the temperature simulation unit 22, the drying simulation unit 23 and the refrigeration unit 31. Among them, the environmental simulation box 1, the unit box 2 and the electric control box 3 are split, and the environmental simulation box 1 and the unit box 2, as well as the unit box 2 and the electric control box 3 are independently assembled.

[0020] By implementing the above-mentioned solar photovoltaic panel environmental simulation system embodiment, controlling the natural wind simulation unit 21, the temperature simulation unit 22, the drying simulation unit 23 and the refrigeration unit 31, a variety of complex environmental conditions can be simulated, including natural wind environment, high temperature environment, humidity environment and low temperature environment, so as to comprehensively evaluate the performance of photovoltaic panels in various practical application environments, and be able to quickly set and change environmental conditions, improve the efficiency of the test, and complete the test of photovoltaic panels under different environmental conditions in a shorter time, saving test time and resources. In order to accurately evaluate the power generation efficiency of photovoltaic panels under different temperature and humidity conditions, it is helpful to understand the performance change trend of photovoltaic panels and provide a basis for the maintenance and optimization of photovoltaic systems.

[0021] Furthermore, combined with Figure 3 As shown, the photovoltaic positioning unit 11 includes a bracket assembly and a positioning assembly arranged on the bracket assembly. The bracket assembly includes a vertical frame 111 and a plurality of beams 112 arranged vertically on the vertical frame 111. The positioning assembly includes a plurality of positioning members 113 arranged on the beam 112 along the length direction of the beam 112, and the positioning members 113 are provided with a slot corresponding to the thickness of the photovoltaic panel, and the sizes of the slots on the plurality of positioning members 113 are different.

[0022] Through the implementation of the above-mentioned solar photovoltaic panel environmental simulation system embodiment, the photovoltaic positioning unit 11 can adapt to photovoltaic panels of different thicknesses and sizes, that is, the different sizes of the slots on the multiple positioning members 113 are utilized to meet the installation requirements of different photovoltaic panels. By using the slots, the precise installation of the photovoltaic panels on the bracket assembly can be ensured, reducing the performance loss caused by inaccurate installation. At the same time, the slot design of the positioning member 113 allows the photovoltaic panels to be quickly installed or replaced, which is particularly useful for occasions where photovoltaic panels need to be replaced frequently, such as testing or maintenance. Since the positioning member 113 is arranged along the length direction of the beam 112, multiple photovoltaic panels can be placed side by side on the vertical frame 111 for simultaneous testing of photovoltaic panels of different sizes.

[0023] Furthermore, the support assembly further includes a horizontally arranged base plate 114. The vertical frame 111 is arranged on one side of the base plate 114, and connecting oblique rods 115 are arranged on the sides of both sides of the vertical frame 111. The end of the connecting oblique rod 115 away from the vertical frame 111 is connected to the side of the corresponding side of the base plate 114, so that a triangular frame is formed between the connecting oblique rod 115, the base plate 114 and the vertical frame 111.

[0024] By implementing the above-mentioned solar photovoltaic panel environmental simulation system embodiment, the triangular frame structure formed by connecting the inclined rods 115, the substrate 114 and the vertical frame 111 can be used to improve the stability of the connection between the entire substrate 114 and the vertical frame 111, so that multiple photovoltaic panels can be placed and supported on the vertical frame 111 at the same time.

[0025] Furthermore, a slide groove 1141 corresponding to the thickness of the photovoltaic panel is provided on the top surface of the substrate 114, so that the photovoltaic panel can slide along the slide groove 1141 and be positioned on the substrate 114. Both ends of the slide groove 1141 are open, a water receiving tray is provided at the bottom of the environmental simulation box 1, and a drainage port connected to the water receiving tray is provided at the bottom of the environmental simulation box 1.

[0026] Through the implementation of the above-mentioned solar photovoltaic panel environmental simulation system embodiment, the photovoltaic panel can be easily slid into and positioned on the substrate 114 by using the slide groove 1141 set on the top surface of the substrate 114, which simplifies the installation and adjustment process of the photovoltaic panel, and can adapt to photovoltaic panels of different thicknesses and sizes, thereby improving the versatility and flexibility of the system. At the same time, since the photovoltaic panel can slide along the slide groove 1141, the photovoltaic panel can be easily removed and replaced during maintenance, which is convenient for cleaning and maintenance. In addition, by using the setting of the water receiving tray, when simulating the humidity environment in the environmental simulation box 1, it can be ensured that the accumulated water in the environmental simulation box 1 can be discharged in time, thereby avoiding the damage of the accumulated water to the photovoltaic panel and the internal components of the system.

[0027] Furthermore, combined with Figure 2 and Figure 4 As shown, the natural wind simulation unit 21 includes a circulation motor 211 disposed on the top of the unit box 2, and a circulation wind drum 212 disposed on the top of the unit box 2. The driving end of the circulation motor 211 is connected to the driving input end of the circulation wind drum 212, and the air outlet of the circulation wind drum 212 is connected to the inside of the environmental simulation box 1.

[0028] By implementing the above-mentioned solar photovoltaic panel environment simulation system embodiment, the combination of the circulating motor 211 and the circulating wind drum 212 can ensure that the wind speed inside the environment simulation box 1 is evenly distributed. By adjusting the speed of the circulating motor 211, the simulated wind speed can be changed, so that tests under different wind speed conditions can be performed, which helps to evaluate the performance of the system under different wind speeds. At the same time, by simulating the natural wind environment, possible wind load problems of photovoltaic panels can be discovered and solved in advance, thereby extending the service life of photovoltaic panels.

[0029] Furthermore, a plurality of air outlet holes 116 are provided at the bottom of the box wall adjacent to the environment simulation box 1 and the unit box 2 . The air outlet holes 116 are connected to the inside of the unit box 2 , and the air outlet holes 116 are connected to the air inlet of the circulating air drum 212 through the air duct 24 .

[0030] By implementing the above-mentioned solar photovoltaic panel environmental simulation system embodiment, the air outlet 116 provided between the environmental simulation box 1 and the unit box 2 is used to allow air to flow from the environmental simulation box 1 to the unit box 2 and enter the air duct 24, and be sucked in by the circulating wind drum 212, so that the air forms a continuous cycle between the environmental simulation box 1 and the unit box 2 to simulate the required environmental conditions inside the environmental simulation box 1. By recycling the air, the consumption of external air is reduced, thereby saving energy, and providing controllable and repeatable natural wind simulation environmental conditions, which helps to improve the accuracy and reliability of the test.

[0031] Furthermore, combined with Figure 5 As shown, the humidity simulation unit 32 includes a humidifier 321 disposed in the electric control box 3 and a humidity sensor disposed in the environmental simulation box 1, and the humidifier 321 is connected to the air duct 24. The temperature simulation unit 22 includes a heater 221 disposed in the unit box 2 and a temperature sensor disposed in the environmental simulation box 1, and the heater 221 is disposed on the air duct 24. The drying simulation unit 23 includes an evaporator 231 disposed in the unit box 2 and a moisture sensor disposed in the environmental simulation box 1, and the evaporator 231 is connected to the air duct 24.

[0032] Through the implementation of the above-mentioned solar photovoltaic panel environmental simulation system embodiment, the humidity, temperature and dryness in the environmental simulation box 1 can be accurately controlled by using the humidifier 321, the heater 221 and the evaporator 231 to meet different test requirements. For example: the humidity simulation unit 32 provides a controllable humidity environment, which helps to evaluate the performance of photovoltaic panels under humid conditions and prevents the photovoltaic panels from corrosion or other damage due to humidity changes; the temperature simulation unit 22 allows the reaction and performance of photovoltaic panels at different temperatures to be tested to evaluate the thermal stability and mechanical properties of the material; the drying simulation unit 23 is used to simulate dry conditions and test the performance of photovoltaic panels in a dry environment to evaluate the durability and weather resistance of the product. Thus, by simulating various climatic conditions, including high temperature, high humidity, low temperature and dry conditions, accurate environmental simulation contributes to the reliability of test results, and can reduce the workload of testing and reduce long-term operating costs.

[0033] Furthermore, the interior of the electric control box 3 is divided into an independent refrigeration chamber and a compression chamber. The refrigeration unit 31 includes a condenser 311 and a heat exchanger 312 arranged in the refrigeration chamber, and a compressor 313 arranged in the compression chamber. The condenser 311 is connected to the heat exchanger 312 for cooling the heat exchange medium in the heat exchanger 312. The compressor 313 is provided with an air inlet and an air outlet, and the heat exchanger 312 is connected to the compressor 313 for cooling the compressed air in the compressor 313, and the air outlet of the compressor 313 is connected to the air duct 24. A thermal insulation cotton layer is provided on the inner wall of the refrigeration chamber, and a shock-absorbing spring pad is provided at the bottom of the compressor 313.

[0034] Through the implementation of the above-mentioned solar photovoltaic panel environmental simulation system embodiment, the refrigeration chamber and the compression chamber are separated and set so that each chamber can be controlled and optimized separately. By using the combination of the condenser 311 and the heat exchanger 312, the heat exchange medium in the heat exchanger 312 can be effectively cooled to improve the refrigeration efficiency. The compressor 313 and the heat exchanger 312 are used to exchange heat to cool the compressed air in the compressor 313, so that the compressor 313 blows the low-temperature air into the environmental simulation box 1 through the air duct 24 to simulate the low-temperature environment. In addition, by setting a thermal insulation cotton layer on the inner wall of the refrigeration chamber, the external heat can be effectively blocked from entering the refrigeration chamber, reducing heat conduction, thereby reducing the energy consumption of the refrigeration unit 31, and improving the refrigeration efficiency, reducing the workload of the compressor 313. At the same time, by setting a shock-absorbing spring pad at the bottom of the compressor 313, the vibration generated when the compressor 313 is running can be effectively absorbed, reducing the impact on the equipment itself and the surrounding environment.

[0035] Furthermore, combined with Figure 2 and Figure 6As shown, the environmental simulation module also includes a moisture-proof lighting unit 4 arranged above the environmental simulation box 1. The moisture-proof lighting unit 4 includes a position adjustment component and a moisture-proof lamp arranged on the position adjustment component. The position adjustment component includes a top main frame 41, a top traverse frame 42, a traverse drive push rod, a top lifting frame 43, a lift drive push rod 44 and a lampshade 45. The top traverse frame 42 is slidably arranged on the top main frame 41, the traverse drive push rod is arranged on one side of the top traverse frame 42, and the push end of the traverse drive push rod is connected to the top traverse frame 42. The top lifting frame 43 is laid flat on the top traverse frame 42, the lift drive push rod 44 is arranged on the top traverse frame 42, and the push rod end of the lift drive push rod 44 is connected to the top lifting frame 43. The lampshade 45 is arranged on the top lifting frame 43, and a plurality of lampshades 45 are distributed along the length direction of the top lifting frame 43, and a moisture-proof lamp is arranged in each lampshade 45. A guide through hole corresponding to the lampshade 45 is disposed on the top wall of the environmental simulation box 1 , and a receiving groove corresponding to the lampshade 45 is disposed on one side of the guide through hole on the top outer wall of the environmental simulation box 1 .

[0036] By implementing the above-mentioned solar photovoltaic panel environmental simulation system embodiment, the top lifting frame 43 is driven to lift by the lifting driving push rod 44, and the multiple lampshades 45 on the top lifting frame 43 can be driven to lift at the same time, so that the lampshades 45 are placed into or lifted out of the environmental simulation box 1 along the guide through hole. That is, when the environmental simulation box 1 is in a humid or high humidity environment, the lampshades 45 are controlled to be placed into the environmental simulation box 1 along the guide through hole, so that the moisture-proof lamp in the lampshades 45 provides sufficient lighting, ensuring that the operator can clearly observe the environment inside the environmental simulation box 1 under humid conditions.

[0037] On the contrary, when the environmental simulation is finished, the top lifting frame 43 is driven to rise by the lifting driving push rod 44, so that the lampshade 45 is lifted away from the environmental simulation box 1 along the guide through hole, until the lampshade 45 is completely lifted away from the guide through hole, and the top transverse frame 42 is driven to slide on the top main frame 41 by the transverse driving push rod, which can simultaneously drive the top lifting frame 43 to move transversely until the lampshade 45 is moved to the top of the receiving groove. Then, the top lifting frame 43 is driven to descend by the lifting driving push rod 44, so as to drive the multiple lampshades 45 on the top lifting frame 43 to be placed in the corresponding receiving grooves, so as to realize the accommodation of the moisture-proof lamp when the solar photovoltaic panel environmental simulation system is shut down and unloaded, so as to prevent the moisture-proof lamp from being continuously affected by the external environment, thereby extending the service life of the moisture-proof lamp.
