Description

Technical Field

[0002] Solar photovoltaic (PV) power generation is one of the fastest-growing and most promising renewable energy industries. In recent years, with the increasing demand for PV power generation and the growing need for clean energy, the application of PV power generation systems has become increasingly widespread. However, solar cell modules are susceptible to environmental factors during long-term use, leading to problems such as internal defects, microcracks, fragmentation, and poor soldering. These defects reduce the conversion efficiency of solar cell modules, affect their power generation performance, and may even cause safety hazards, thus shortening their lifespan. Therefore, regular inspection of solar cell modules is crucial.

[0003] Traditional electroluminescence detection methods mostly involve manual handheld imaging or imaging with equipment mounted on a fixed tripod. Photovoltaic modules are installed at high heights, making electroluminescence detection inconvenient. Manually capturing images of photovoltaic modules is labor-intensive, inefficient, and lacks stability, leading to inaccurate results. Using equipment mounted on a fixed tripod also presents challenges due to the inability to adjust the shooting position and angle, further reducing detection efficiency. With the increasing scale of photovoltaic power plants and the growing number of solar cell modules, traditional electroluminescence detection methods are struggling to meet the demands.

[0029] Example 1

[0030] like Figures 1-4As shown, this embodiment provides a support device 100, including a support frame 1, a moving device 2, and a rotating platform 3. The moving device 2 is connected to the support frame 1, and the rotating platform 3 is connected to the moving device 2. The moving device 2 can drive the rotating platform 3 to reciprocate along a first direction and can maintain the rotating platform 3 at a set position. The angle between the first direction and the horizontal plane is an acute angle. The rotating platform 3 is used to mount a shooting device 4, and the rotating platform 3 can at least drive the shooting device 4 to rotate along an axis perpendicular to the first direction. The support frame 1 is placed opposite the object to be photographed, and the end of the moving device 2 away from the support frame 1 extends towards the object to be photographed. Since the moving device 2 is inclined relative to the horizontal plane, when the moving device 2 drives the rotating platform 3 to reciprocate along the first direction, it can simultaneously adjust the height of the rotating platform 3 and the distance between the rotating platform 3 and the object to be photographed, thereby adjusting the height of the shooting device 4 and the distance between the shooting device 4 and the object to be photographed. The position adjustment in two directions is achieved with a relatively simple structure. The rotating platform 3 can drive the shooting device 4 to rotate along an axis perpendicular to the first direction, which can make the shooting device 4 swing left and right, changing the shooting angle of the shooting device 4. The support frame 1 is used to support the imaging device 4, providing greater stability during imaging compared to manual shooting. This embodiment features a simple structure, ensuring imaging stability and allowing for various adjustments to the imaging device 4. This reduces errors and limitations associated with manual operation, ensuring accurate detection results and improving detection efficiency.

[0031] In some specific embodiments, the moving device 2 includes a lead screw 201, a slider, a guide rail, and a drive device 202. Both the lead screw 201 and the guide rail are connected to the support frame 1. The drive device 202 is connected to the lead screw 201 and can drive the lead screw 201 to rotate around its axis. The slider is threadedly connected to the lead screw 201 and slidably connected to the guide rail. The slider is also connected to the rotary table 3. The axial direction of the lead screw 201 is a first direction, and the length direction of the guide rail is parallel to the first direction. When the drive device 202 rotates, it causes the lead screw 201 to rotate. Guided by the guide rail, the slider moves along the lead screw 201, thereby moving the rotary table 3 along the first direction. When the set position is reached, the drive device 202 stops driving, and the slider can maintain its position at the corresponding position on the lead screw 201.

[0032] In some specific embodiments, the mobile device 2 further includes a drive board, which is signal-connected to the drive device 202. The assembly method of the mobile device 2 is as follows: First, the drive board is fixed on the acrylic plate and then assembled on the drive device 202. Then, the mounting bracket of the drive device 202 is fixed to one end of the rotating shaft of the drive device 202. A rigid coupling is used as a connector between the drive device 202 and the lead screw 201 to connect the two. The slider is then assembled onto the lead screw 201. Finally, the optical shaft of 2040V steel is used as a guide rail. The guide rail passes through the slider, and the guide rail and the lead screw 201 are mounted on the acrylic plate through bearings. Finally, the assembled servo gimbal is assembled onto the mobile device 2.

[0033] In some specific embodiments, the rotating platform 3 is a gimbal, and the rotating platform 3 is fixedly connected to the moving device 2.

The controller can control the start and stop of the moving device 2 so that the shooting device 4 moves along the first direction. The controller can control the start and stop of the rotating platform 3 so as to adjust the shooting angle of the shooting device 4.

[0035] In some specific embodiments, a remote control device is also included, which is communicatively connected to the controller. The remote control device can input control commands related to movement in the first direction and rotation of the turntable 3 to the controller. The controller can then control the movement of the moving device 2 and the turntable 3 according to the remote control commands, and stop the movement after the shooting device 4 reaches the set position. The remote control device is preferably an infrared remote controller.

[0036] In some specific embodiments, the controller can communicate with the shooting device 4 and can also wirelessly communicate with a smartphone, preferably via a Bluetooth module. Data captured by the shooting device 4 can be transmitted to the controller, which can then transmit the captured data to the smartphone, allowing the smartphone to view the footage captured by the shooting device 4. Based on the screen displayed on the smartphone, the controller can be given control commands related to movement in the first direction and rotation of the turntable 3, thereby adjusting the position and angle of the shooting device 4.

[0037] Specifically, a DX-BT18 Bluetooth module can be added to the servo gimbal controlled by an STM32F103 (powered by a lithium battery) to enable remote control of the servo gimbal.

For the lead screw guide module (moving device 2) controlled by a DRV8825, an infrared receiver is integrated on the driver board (powered by a lithium battery). The infrared receiver is driven by a remote control infrared signal, causing the driver device 202 to rotate forward and backward, thereby moving the shooting device 4.

[0038] In some specific embodiments, the support frame 1 can adjust the height of the shooting device 4 by telescopic adjustment to increase the shooting range.
