DETAILED DESCRIPTION

[0017] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0018] Example: See Figure 1-3 , the utility model provides a technical solution: an EL detection device for a photovoltaic power station. This solution takes into account that the traditional manual use of equipment for EL detection of photovoltaic power stations requires frequent climbing up and down, low detection efficiency and potential safety hazards, and low manual detection stability, resulting in poor EL imaging clarity, making it difficult to accurately present relatively minor defects on photovoltaic modules, affecting the detection effect. Based on the above content, this case sets the following technical means;

[0019] Specifically, the device at least includes a mobile base 1, a mounting frame 2, a fixing plate 3, a detection bracket 4, a mounting slot 5, a rotating bracket 6, a pair of mounting tables 7, a pair of gear reducers 8, a pair of driving motors 9, a telescopic bracket 10, a rotating pan-tilt table 11 and an EL tester 12;

[0020] The mobile base 1 supports and fixes the entire equipment. The driving motor 9 is started and rotated under the control of the controller. The driving motor 9 is decelerated through the internal gear transmission of the gear reducer 8 installed on the mounting platform 7 to drive the rotating bracket 6 to rotate on the detection bracket 4 to adjust the pitch angle. The reinforcing rod 14 installed on the fixed plate 3 and the detection bracket 4 by the fixing bolts 15 ensures the stability of the equipment. At the same time, the rotating pan-tilt head 11 drives the EL tester 12 to adjust the angle, so that the EL tester 12 can stably image and shoot the solar panels of the photovoltaic power station, clearly perform imaging detection, and ensure the detection effect.

[0021] Furthermore, a control device is installed on the device, and the control device is connected to the driving motor 9, the rotating pan / tilt 11 and the EL tester 12, and is driven and controlled by a control signal.

[0022] Furthermore, the detection principle of the EL tester 12 in this case is that during detection under dark light conditions, a forward bias is applied to the solar cell to simulate the equivalent DC current generated by sunlight shining on the battery component in actual use. The power supply injects a large number of unbalanced carriers into the solar cell, and the electroluminescence relies on the large number of unbalanced carriers injected from the diffusion area to continuously recombine and emit photons. These photons are then captured by a detection camera, and the light emitted by the solar cell is imaged using a near-infrared imaging system and sent to the computer software. After processing, the EL image of the solar cell is displayed on the screen, thereby explaining the inherent defects that cannot be recognized by the human eye.

[0023] Furthermore, the fixed end of the telescopic bracket 10 in the present technical solution is embedded in the rotating bracket 6, and the telescopic end of the telescopic bracket 10 is exposed outside.

[0024] In the specific implementation process, further, a plurality of moving wheels 13 are installed on the mobile base 1, and the moving wheels 13 facilitate the movement of the equipment, thereby increasing the portability of the detection equipment.

[0025] In the specific implementation process, further, a pair of reinforcing rods 14 are installed on the fixing plate 3 and the detection bracket 4 in cooperation with the fixing bolts 15, and the stability of the detection equipment is ensured by the triangular stable structure formed by them.

[0026] In the specific implementation process, further, a pair of mounting platforms 7 are installed with reinforcing ribs 16, and the installation support is performed through the reinforcing ribs 16.

[0027] In the specific implementation process, further, the rotating pan head 11 is installed on the telescopic bracket 10 through the fixing sleeve 17 .

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
