Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic power plant operation and maintenance equipment technology, specifically a photovoltaic support damage image acquisition device using a track-based method. Background Technology
[0002] With the large-scale development of photovoltaic power plants, the integrity of photovoltaic support structures, as the core structure supporting photovoltaic panels, directly affects the operational safety and power generation efficiency of the power plant. Traditional photovoltaic support damage detection relies on manual inspection, which suffers from low detection efficiency, high labor intensity, and high risks associated with working at heights, and is difficult to adapt to the operation and maintenance needs of large-scale photovoltaic power plants.
[0003] While existing track-based data acquisition devices can achieve automated inspection, they still have many drawbacks: Traditional manual inspections are inefficient and risky, making them unsuitable for large-scale sites. Existing track-mounted data acquisition devices suffer from poor installation adaptability, unstable operation, and unclear target positioning, making it impossible to accurately identify components such as columns, purlins, and braces. Furthermore, the images lack location annotations, making subsequent damage tracing difficult.
[0004] Therefore, it is necessary to improve the photovoltaic support damage image acquisition device using a track-based method to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic support damage image acquisition device using a track system, comprising a track body and an acquisition trolley. The track body is detachably connected to the main beam of the photovoltaic support, and the acquisition trolley is rotatably connected to the track body. A detection component is fixedly connected to the acquisition trolley, a positioning component is provided on the track body, and a position sensor is provided on the acquisition trolley corresponding to the positioning component. The detection component is signal-connected to the position sensor.
[0007] The track body is a hollow rectangular cavity structure with a long opening on the top surface and symmetrical sliding guide rails on the inner sidewalls. Fixing holes are arrayed on the left, right, and bottom sidewalls of the track body, allowing for side, top, or inverted installation via bolts. Splicing bosses are provided at both ends of the track body, and adjacent track bodies are fixed by snapping together through the splicing bosses to ensure the alignment of the guide rails. The positioning element is a permanent magnet marker block embedded in the inner sidewall of the track body at 1m intervals.
[0008] The data acquisition trolley includes a frame and rolling wheels. The rolling wheels are symmetrically connected to both sides of the frame and roll in cooperation with the sliding guide rail. A drive motor is fixedly connected inside the frame, and the output shaft of the drive motor is connected to the rolling wheels for transmission, realizing self-driven operation. The position sensor is a Hall sensor, which is fixed on the outer wall of the frame and corresponds to the position of the permanent magnet marker block. It is used for positioning and calibration of the data acquisition trolley.
[0009] The detection assembly includes a rotating base, a high-definition camera, and a laser rangefinder. The rotating base is fixed to the top of the vehicle frame and can rotate 360° horizontally and ±30° vertically. The high-definition camera and the laser rangefinder are fixed side by side to the top of the rotating base, with the laser rangefinder emitting in the same direction as the camera. An angle sensor is fixed on the rotating base to collect shooting angle data. A control module is fixed on the vehicle frame, and the control module is connected to the drive motor, position sensor, rotating base, high-definition camera, laser rangefinder, and angle sensor. It can store and label track numbers, collection positions, angles, and distance information.
[0010] Compared with the prior art, this utility model provides a photovoltaic support damage image acquisition device using a track-based method, which has the following beneficial effects: 1. Simplified structure: The track body is quickly assembled through splicing bosses, and the data acquisition trolley integrates drive and detection functions, reducing redundant parts and lowering the difficulty of installation and maintenance; the multi-directional fixing hole design adapts to different photovoltaic brackets, solving the problem of poor adaptability of traditional tracks.
[0011] 2. The permanent magnet marker block, in conjunction with the Hall sensor and data from the angle sensor and laser rangefinder, can accurately locate the acquisition position and the target to be photographed, and automatically identify components such as columns and purlins, solving the problem of ambiguous positioning and facilitating damage tracing.
[0012] 3. The automated operation design eliminates the need for manual intervention, improving inspection efficiency and avoiding the risks of working at heights; it also associates and labels the location, angle, and distance information of collected images, reducing the difficulty of subsequent damage identification and adapting to the operation and maintenance needs of large photovoltaic power plants.

[0017] Example: Please see Figure 1-4 This utility model provides a technical solution: a photovoltaic bracket damage image acquisition device using a track method, including a track body 1 and an acquisition trolley 2. The track body 1 is detachably connected to the main beam of the photovoltaic bracket, and the acquisition trolley 2 is rotatably connected to the track body 1. A detection component 3 is fixedly connected to the acquisition trolley 2. A positioning component 16 is provided on the track body 1, and a position sensor 23 is provided on the acquisition trolley 2 corresponding to the positioning component 16. The detection component 3 is signal-connected to the position sensor 23.
[0018] The track body 1 is a hollow rectangular cavity 11 with an elongated opening 12 on the top surface for the detection component 3 to extend out. The inner sidewalls are symmetrically provided with sliding guide rails 13 to reduce rolling resistance. The left and right sidewalls and bottom wall of the track body 1 are all provided with arrayed fixing holes 14 to flexibly adapt to different installation scenarios. There are splicing bosses 15 at both ends, and adjacent track bodies 1 are fixed by splicing bosses 15 to ensure that the sliding guide rails 13 are aligned. The positioning component 16 is a permanent magnet marker block embedded at 1m intervals for position calibration.
[0019] The data acquisition trolley 2 includes a frame 21 and rolling wheels 22. The rolling wheels 22 are symmetrically connected to both sides of the frame 21 and roll in cooperation with the sliding guide rail 13. A drive motor is fixed inside the frame 21 and is connected to the rolling wheels 22 for transmission to achieve self-drive. The position sensor 23 is a Hall sensor, which is fixed on the outer wall of the frame 21 and corresponds to the permanent magnet marker block to provide real-time feedback of position signals.
[0020] The detection component 3 includes a rotating base 31, a high-definition camera 32, and a laser rangefinder 33.

[0021] Working principle: In use, the track body 1 is installed on the main beam of the photovoltaic support through the fixing holes 14, and multiple track sections are spliced and fixed by the splicing bosses 15. Pre-set shooting angle parameters for different components, the control module 4 starts the drive motor, driving the acquisition trolley 2 to run along the sliding guide rail 13.

Engineers can quickly identify damaged components and their locations using the labeled images to complete maintenance and inspection.
