Among them, a photovoltaic module 2 is arranged on the top of the support frame 1; the settlement monitoring unit can monitor the settlement of the support frame 1 at various positions; the hydraulic support unit 3 includes a plurality of hydraulic rods 31, and the plurality of hydraulic rods 31 are arranged at intervals, and the telescopic ends of the hydraulic rods 31 are connected to the support frame 1, and the hydraulic rods 31 can drive the support frame 1 at a preset position to move along a first direction, and the first direction is the height direction of the support frame 1, and the control end of the hydraulic rod 31 is connected to the settlement monitoring unit signal.

[0028] After the photovoltaic support structure in this embodiment monitors the settlement position of the support frame 1 through the settlement monitoring unit, the settlement position of the support frame 1 can be lifted by the hydraulic rod 31 in the hydraulic support unit 3, thereby realizing safe adjustment of the photovoltaic support; its overall structure is simple, which can ensure that the photovoltaic power generation system can cope with the uneven settlement of the mining subsidence area, realize the safe and stable operation of the photovoltaic power generation system, and facilitate on-site construction and later operation and maintenance.

The purlins 12 are arranged on the inclined beams 13 at intervals along the length direction of the support frame 1, and the telescopic end of the hydraulic rod 31 is directly or indirectly connected to the inclined beam 13 and / or the purlin 12.

[0030] like Figure 1-2As shown, in a specific embodiment, the hydraulic support unit 3 further includes a top support 32 and a support base 33. The top support 32 is arranged at the top of the hydraulic rod 31, and the top support 32 connects the hydraulic rod 31 and the purlin 12. The support base 33 is located at the bottom of the hydraulic rod 31, and the surface area of ​​the support base 33 is larger than the surface area of ​​the bottom of the hydraulic rod 31. The top support 32 can ensure that the hydraulic rod 31 is in safe and stable contact with the purlin 12 or the inclined beam 13, and the connection is more stable while ensuring that the hydraulic rod 31 will not damage the purlin 12 or the inclined beam 13 when the height is adjusted, and the support base 33 can increase the contact area with the ground, thereby preventing the hydraulic rod 31 from sinking significantly.

[0031] In a specific embodiment, the settlement monitoring unit includes a high-precision drone scanning device and an elevation data processing module. The high-precision drone scanning device can scan the support frame 1 at multiple positions, and the elevation data processing module is used to analyze and process the scanned data.

In addition, the elevation data processing module can compare and analyze the scanning data of the high-precision drone scanning device to determine whether the adjustment critical value of the photovoltaic bracket is reached. If the critical value is reached, a data instruction is issued to adjust the height of the support frame 1 at the settlement position, thereby ensuring the safe and stable operation of the photovoltaic power generation system.
