Problems solved by technology

[0005] The following defects exist in the above-mentioned debugging process: it is difficult to determine that the plane of the concentrator is perpendicular to the optical axis when placing the concentrator; The manual operation and the existence of visual errors will lead to an increase in the error of measurement and calibration, making it impossible to meet the accuracy requirements, thus requiring repeated operation and positioning. Therefore, the operation process is complicated and cumbersome, and it requires the cooperation of multiple people to complete, which is time-consuming and laborious.
This requires transferring the spatial distance of each plane to the debugging platform for measurement, and there are operational errors in the process of target transfer and distance measurement

Embodiment 1

[0041] like Figure 1-8 Shown is a multifunctional laser device for concentrating photovoltaic testing of the present invention, including a cross-shaped support, a first laser emitting device 4 and a second laser emitting device 5, and the support is mainly composed of a vertical rod 2 and a sliding installation on the vertical The crossbar 3 on the pole 2 is composed of a crossbar 3 that can move up and down along the vertical pole 2 and can rotate around the vertical pole 2. There are two first laser emitting devices 4 that are slidably installed on the crossbar 3 and can move along the crossbar 3 , the second laser emitting device 5 is two and is slidably mounted on the vertical bar 2 and can move along the vertical bar 2. The first laser emitting device 4 and the second laser emitting device 5 have a rotatable part, and the first and second laser emitting devices The rotatable part of the device is provided with a laser emitting head 6, the horizontal bar 3 and the vertic...

Embodiment 2

[0056] like Figure 12 As shown, the difference between this embodiment and Embodiment 1 is that: no second laser emitting device is installed on the vertical bar 2 , and four first laser emitting devices 4 are installed on the horizontal bar 3 . The number of first laser emitting devices arranged on the crossbar should be the same as the number of required measuring devices.

[0057] Application: Continuing from Example 1, after the multiplier is adjusted, the distance between the light source outlet and the plane of each device (concentrator and battery) needs to be known, so that the multiplier adjustment can be repeated in subsequent tests.

[0058] In this embodiment, each device is a concentrator 002, 003, a battery 004, and an optical axis indicating laser element 01. The starting angle of the first laser emitting device is 0°, the scales of the horizontal bar and the vertical bar are facing the operation surface, and at this time, the horizontal bar is located on the ...
