[0034] The detection mechanism includes a lifting assembly, a sliding assembly, and a rotating assembly. The rotating assembly includes a motor 15, which drives the rotating assembly. The motor 15 is installed inside the control box 6, which protects the motor 15 from external wind and sand. A gear 2 17 is fixedly connected to the output end of the motor 15, which is driven by the motor 15. A gear 16 is fixedly connected to the lower part of the rotating table 4, which drives the rotating table 4 to rotate. The gear 16 meshes with the gear 2 17, and the motor can be driven by the meshing of the gear 16 and the gear 2 17. The rotating table 4 is rotated back and forth by the motor 15, which can adjust the upper detector 5, change the direction of the detector 5, increase the detection range, and avoid blind spots that would prevent timely detection of damage to the power generation device.

[0035] Figure 2 and Figure 4 The lifting assembly includes a fixed cover 21, which is fixedly connected to the top of the rotary table 4. A second motor 20 is mounted on the fixed cover 21, and the second motor 20 is installed inside the fixed cover 21. The second motor 20 drives the lifting assembly. A threaded rod 18 is fixedly connected to the output end of the second motor 20. The threaded rod 18 rotates with the second motor 20. A threaded sleeve 14 is threadedly connected to the outside of the threaded rod 18. The threaded sleeve 14 moves outside the threaded rod 18. A movable plate 8 is fixedly connected to the top of the threaded sleeve 14. The movable plate 8 moves through the threaded sleeve 14. A lifting groove 19 is opened inside the movable plate 8, which provides space for the movement of the threaded rod 18. The threaded rod 18 is located inside the lifting groove 19. The second motor 20 drives the threaded rod 18 to rotate and adjust the movable plate 8, allowing the movable plate 8 to move up and down, thereby moving the detection device.

[0036] Figure 1 , Figure 2 and Figure 5The sliding assembly includes a support rod 12, one end of which is rotatably connected to the top of the rotary table 4 and used to connect to the mounting plate 11. The other end of the support rod 12 is rotatably connected to the slider 23, which moves the slider 23. A support rod 13 is rotatably connected to one side of the support rod 12.

A fixing block 24 is rotatably connected to one side of the support rod 13, and the mounting plate 11 is fixedly connected to one side of the fixing block 24. The mounting plate 11 is fixed by the support rod 13 and the fixing block 24. The fixing block 24 allows the support rod 13 to rotate on one side of the mounting plate 11. A groove 22 is provided on the inner side to provide moving space for the slider 23. The slider 23 is slidably connected inside the groove 22. The groove 22 can limit the range of movement of the slider 23. One end of the support rod 13 is rotatably connected to one side of the threaded sleeve 14. The threaded sleeve 14 drives the support rod 13 to rotate. The detector 5 is installed on the outside of the mounting plate 11. When the mounting plate 11 moves, the detector 5 can move. The detection mechanism is installed on the top of the rotary table 4 using a sliding assembly. When the two support rods rotate, the mounting plate 11 on one side can move, driving the detector 5 to move and place the detector 5 under the moving plate 8. The moving plate 8 protects the detector 5 and prevents damage.

[0037] Figure 1 The support column 1 is fixedly connected to a base 2 at its bottom. The support column 1 is installed on the base 2. The base 2 has multiple fixing holes 3 inside, which fix the base 2. The control box 6 has multiple connection ports 7 at its bottom, which are connected to the combiner box. The control box 6 can detect the photovoltaic module signal and detect its damage in time. The wind detector 10 is installed on the top of the moving plate 8. The wind detector 10 can detect the wind direction and wind force. The signal antenna 9 is fixedly connected to the top of the moving plate 8 to enhance the signal transmission of the monitoring device.

[0038] Working principle: First, drive motor 15 rotates, which drives gear 17 fixed at the output end to rotate. Gear 17 rotates, which drives gear 16 meshing with it to rotate. Gear 16 allows the rotating platform 4 at the top of the support column 1 to rotate. The rotation of the rotating platform 4 changes the direction of the detector 5 installed on the upper part, making the detection range more comprehensive and enabling timely detection of problems. Then, start motor 20, which drives the threaded rod 18 at the output end to rotate. The rotation of the threaded rod 18 drives the outer threaded sleeve 14 to rotate. The threaded sleeve 14 is fixed at the bottom of the moving plate 8. Therefore, the moving plate 8 can be moved up and down by the threaded rod 18 through the threaded sleeve 14. The lifting groove 19 inside the moving plate 8 provides space for the threaded rod 18.

[0039] Secondly, when the threaded sleeve 14 moves with the moving plate 8, it drives the outer support rod 13 to rotate on it. The support rod 12 and the support rod 13 rotate relative to each other, changing the distance between their ends. This allows the support rod 12 to drive the slider 23 to slide inside the slide groove 22, changing the position of the mounting plate 11. This allows the detector 5 to move towards the center, moving the detector 5 below the moving plate 8 to protect it, extend its service life, and better detect the status of the power generation device. A control box 6 is installed on the outside of the support column 1 to connect the photovoltaic module signal to the connection port 7, enabling timely detection of the status of the power generation device.

[0040] The detectors are used to detect abnormal conditions such as equipment vibration and falling components. One detector is installed at the center of the main beam of each photovoltaic support unit, forming a grid-like monitoring network from "subarray level" to "support level." The detectors capture the vibration amplitude, frequency characteristics, and impact energy of the photovoltaic panel supports in real time, distinguishing between three types of abnormalities: normal wind vibration, loose bolts, and component detachment. Then, using the information measured by the detectors, the specific location and extent of damage to the photovoltaic modules in the photovoltaic power station can be quickly pinpointed. Maintenance personnel can quickly assess the damage to the modules and replace them promptly, reducing the time spent on manual inspection and improving work efficiency.

[0041] Detector warning threshold setting: Dynamic threshold setting is based on historical data to establish a benchmark vibration model, for example: (1) Normal wind vibration: RMS (Root Mean Square) acceleration <0.5g, duration <30s; (2) Loosening warning: RMS >1.2g for 5 consecutive sampling points and a 15Hz peak appears in the spectrum; (3) Fall risk: Single impact acceleration >8g and accompanied by high-frequency decay vibration.

[0042] Tiered warning: (1) Level 1 warning: push loose alarm information through the monitoring backend; (2) Level 2 warning: push loose risk alarm information through the monitoring backend; (3) Level 3 warning: push component drop alarm information through the monitoring backend when the component is detected to have fallen.

[0043] Alarm signal acquisition in the monitoring background: (1) Transmit the signal in the control box to the signal collector; (2) Install the signal collector in the combiner box in a centralized manner, transfer the collected signal to the sub-array communication management unit through 485 communication, and the sub-array communication management unit sends the information to the station control layer switch, and the background directly calls; (3) If it is a string inverter, a signal collector needs to be installed on the low voltage side of the transformer box, and after collecting the information, send the information to the station control layer switch using a dedicated optical fiber or the remote signaling interface of the transformer box measurement and control device, and the background directly calls.

[0044] When selecting detectors, in high-altitude new energy photovoltaic plants, the detectors must meet the requirements of high reliability, high precision, anti-interference and long life under extreme environments.

[0045] (1) Wide temperature range adaptability: High-altitude areas have large diurnal temperature differences, and the detector needs to operate stably in extreme temperatures ranging from -40℃ to +85℃. Low-temperature resistant materials and low-temperature compensation circuits are required to ensure that the signal is not distorted in low-temperature environments;

[0046] (2) High protection level: protected against sand, rain, snow and salt spray corrosion. The detector housing should be made of stainless steel or engineering plastic and equipped with sealing rings and a moisture-proof breather valve;

[0047] (3) Electromagnetic interference resistance: Thunderstorms are frequent in high-altitude areas, so the detector must be able to resist lightning surges and use shielded twisted pair or optical fiber to transmit signals.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
