Description

Technical Field

[0001] This utility model relates to the field of photovoltaic system operation and maintenance technology, specifically a testing device for system operation and maintenance. Background Technology

[0002] A photovoltaic (PV) power station is a power generation system that utilizes solar energy, employs special materials such as crystalline silicon panels, inverters, and other electronic components, and is connected to the power grid to transmit electricity to it. After the PV panels in a PV power station are installed or have been in use for a period of time, an EL (Elastic Optical Array) detector is needed to inspect the PV panels for internal defects, microcracks, fragments, poor soldering, broken grids, and abnormal phenomena in individual cells with different conversion efficiencies.

[0003] A search revealed that patent CN222255915U discloses a portable EL detector. By adjusting the length of the telescopic rod, the mounting base can be rotated in the vertical direction. The mounting base drives the infrared camera to rotate, thereby adjusting the tilt angle of the infrared camera and effectively improving the convenience for inspectors to adjust the tilt angle of the infrared camera.

[0004] By rotating the lifting rod, the lifting rod can be moved away from or towards the support sleeve. The lifting rod can then drive the mounting base to rise or fall, thereby adjusting the height of the infrared camera and effectively improving the convenience for inspection personnel to adjust the height of the infrared camera.

[0005] By rotating the turntable, the infrared camera can be rotated horizontally. Then, the turntable is positioned on the lifting rod by the positioning component, which allows for convenient and quick adjustment of the infrared camera's horizontal angle.

[0006] While the above solution can adjust the height and lens angle of the infrared camera, its structure is too complex. Furthermore, since the height adjustment is achieved through the threaded connection between the lifting rod and the support sleeve, the lifting rod needs to be rotated on the support sleeve. However, the lifting rod is fixed to the turntable, so rotating it on the support sleeve causes the infrared camera to rotate as well, resulting in a change in the camera's lens orientation. Therefore, after adjusting the infrared camera's height, the entire frame needs to be rearranged to re-align the camera's lens with the target direction, making it inconvenient to use and requiring improvement.

[0012] As a further embodiment of this utility model: the connecting seat has an annular groove on its outer wall inside the sleeve, and the width of the annular groove is adapted to the outer diameter of the first screw.

[0013] As a further improvement of this utility model: a third hand-tightening bolt is movably installed at the bottom of the slider, and a threaded hole adapted to the third hand-tightening bolt is provided at the bottom of the infrared machine.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When deploying the infrared camera, this invention first adjusts the three telescopic legs to the required length and angle, then supports the base in the desired position. Next, the infrared camera is mounted on the slider, which is then mounted on the sliding sleeve. Rotating the screw relative to the internal threaded tube adjusts the height of the infrared camera. Then, rotating the sleeve on the connecting seat allows the camera's lens to face the desired direction. Finally, rotating the collar on the rotating shaft adjusts the camera's tilt, ensuring the camera is aligned with the target. The operation is simple and convenient, requiring no repositioning of the entire device, and the results are excellent. Attached Figure Description
