[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to convert light energy into electrical energy. It is mainly composed of photovoltaic modules, controllers and inverters, and photovoltaic modules are its core units. In order to ensure stable power generation of photovoltaic systems, photovoltaic modules are usually placed outdoors, but the influence of the external environment will inevitably affect their performance and quality.

[0003] Photovoltaic module manufacturers will verify the quality of their products before they leave the factory. The usual practice is to use equipment such as UV aging chambers, salt spray chambers, or composite salt spray UV aging test chambers to simulate various outdoor environmental climate conditions.

[0004] However, the existing aging test chambers have some limitations, including that the direction of the sunlight simulation light source is usually vertically downward or sideways, and the irradiation surface is fixed and cannot be adjusted. In this case, it is impossible to meet the experimental requirements under various complex working conditions. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem in the prior art that the irradiation direction of the light source of the aging test box for photovoltaic components cannot be adjusted, resulting in the inability to meet the experimental requirements under various complex working conditions.

[0019] In one embodiment of the present invention, the first irradiation lamp and the second irradiation lamp are ultraviolet lamps.

[0020] The above technical solution of the utility model has the following advantages compared with the prior art:

[0021] The utility model discloses an angle-adjustable irradiation device for an aging test chamber, which can realize irradiation planes at different angles and keep the irradiation angle of the light source always perpendicular to the irradiation plane, thereby meeting the experimental requirements under various complex working conditions. The angle driving component can flexibly control the rotation directions of multiple irradiation lamps and ensure their synchronous control, thereby realizing fast and accurate adjustment of the angle of the irradiation lamp.

[0037] Reference Figure 1 , Figure 2 , Figure 3 As shown, the utility model is an angle-adjustable irradiation device for an aging test box, the aging test box includes a box body 1, including:

[0038] The first supporting surface 11 and the second supporting surface 12 are symmetrically arranged on the top of the box body 1;

[0039] The angle driving assembly 2 comprises a driving motor 21, a first driving shaft 22 connected to the output end of the driving motor 21, and a second driving shaft 23 which is drivingly connected to the first driving shaft 22 and has an opposite rotation direction;

[0040] A plurality of first irradiation lamps 3 are rotatably connected to the first supporting surface 11, and each of the first irradiation lamps 3 is connected to a first adjustment shaft 24 which is transmission-connected to the first driving shaft 22 and has the same rotation direction;

[0041] A plurality of second irradiation lamps 4 are rotatably connected to the second supporting surface 12 , and each of the second irradiation lamps 4 is connected to a second adjustment shaft 25 which is transmission-connected to the second driving shaft 23 and has the same rotation direction as the second driving shaft 23 .

[0042] In one embodiment, the first supporting surface 11 and the second supporting surface 12 are connected and extend in a downward direction inclined toward a horizontal plane along their connecting line.

[0043] In one embodiment, a first transmission gear 221 is installed on the first driving shaft 22 , and a second transmission gear 231 meshing with the first transmission gear 221 is installed on the second driving shaft 23 .

[0044] In order to achieve synchronous rotation of the irradiation lamps on the first supporting surface 11 and the second supporting surface 12 with the same rotation angle, the transmission ratio between the first transmission gear 221 and the second transmission gear 231 is 1.

[0045] In one embodiment, a coupling 211 is installed between the drive motor 21 and one end of the first drive shaft 22, and seat bearings 212 are installed between the other end of the first drive shaft 22 and the top of the housing 1, and between both ends of the second drive shaft 23 and the top of the housing 1.

[0046] In one embodiment, a plurality of first illumination lamps 3 are arranged in a rectangular array on the first supporting surface 11, a first adjustment shaft 24 is connected between two adjacent first illumination lamps 3 in the direction of the lamp rotation axis, a first synchronous belt mechanism 26 is arranged between two adjacent and parallel first adjustment shafts 24, a first synchronous belt mechanism 27 is arranged between the first adjustment shaft 24 close to the first driving shaft 22 and the first driving shaft 22; the transmission ratios of the first synchronous belt mechanism 26 and the first synchronous belt mechanism 27 are both 1.

Different component installation angles can be achieved by adjusting the installation angle of the support frame 5. An angle sensor (or angle limit switch) can also be set on the first drive shaft 22 and the second drive shaft 23 to feedback the rotation angle of the irradiation lamp.

[0051] The user sets the required irradiation angle through a control system (such as a PLC) according to experimental requirements or specific lighting needs; after the setting is completed, the control system sends corresponding instructions to the drive motor 21 in the angle drive component 2; the drive motor 21 drives the first drive shaft 22 to rotate clockwise and drives each first irradiation lamp 3 to rotate synchronously clockwise, and drives the second drive shaft 23 to rotate counterclockwise through the first drive shaft 22 and drives each first irradiation lamp 3 to rotate synchronously counterclockwise, so that the irradiation lamp reaches a preset irradiation angle.

The irradiation plane of the irradiation lamp can be automatically adjusted to realize automatic angle adjustment and adjustable irradiation surface angle under special experimental conditions, so as to meet different experimental needs. The device can also allow users to specify a specific irradiation angle to meet their specific lighting requirements.
