[0024] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0025] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0026] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.

[0027] like Figure 1-3 As shown, an embodiment of the present application provides a photovoltaic support structure for coping with uneven foundation settlement, comprising a support frame 1, a settlement monitoring unit, and a hydraulic support unit 3. A photovoltaic module 2 is provided on top of the support frame 1; the settlement monitoring unit is capable of monitoring the settlement of the support frame 1 at various locations; and the hydraulic support unit 3 comprises a plurality of hydraulic rods 31 arranged at intervals. The telescopic ends of the hydraulic rods 31 are connected to the support frame 1 and are capable of driving the support frame 1 at a preset position to move in a first direction, which is the height direction of the support frame 1. The control ends of the hydraulic rods 31 are signal-connected to the settlement monitoring unit.

[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 subsequent operation and maintenance.

[0029] like Figure 1 As shown, in a specific embodiment, the support frame 1 includes a plurality of columns 11, a plurality of purlins 12 and a plurality of inclined beams 13. The plurality of columns 11 are arranged at intervals along the length and width directions of the support frame 1. The inclined beams 13 are located at the tops of the columns 11, and the inclined beams 13 connect two opposite columns 11. The purlins 12 are arranged on the inclined beams 13 at intervals along the length direction of the support frame 1, and the telescopic ends of the hydraulic rods 31 are directly or indirectly connected to the inclined beams 13 and / or the purlins 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 disposed on the top of the hydraulic rod 31 and 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 ensures safe and stable contact between the hydraulic rod 31 and the purlin 12 or the diagonal beam 13. While providing a more stable connection, it also ensures that the hydraulic rod 31 does not damage the purlin 12 or the diagonal beam 13 during height adjustment. The support base 33 increases the contact area with the ground, thereby preventing the hydraulic rod 31 from significantly sinking.

[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. Specifically, the specific monitoring scheme of the high-precision drone scanning device (such as monitoring frequency, flight altitude, hovering time, site range division, etc.) can be determined according to the actual needs of the engineering project, and this article does not make specific restrictions on this. 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.

[0032] like Figure 2-3 As shown, in a specific embodiment, the column 11 includes a first column 14 and a second column 15, the first column 14 is arranged in the second column 15, and the first column 14 can slide relative to the second column 15 along the length direction; the photovoltaic support structure also includes a column adjustment unit 4, the column adjustment unit 4 is used to adjust the length of the first column 14 relative to the second column 15 and fix it.

[0033] Specifically, the column adjustment unit 4 includes a plurality of first holes 41, a plurality of second holes 42, and at least two connecting members. The plurality of first holes 41 are spaced apart on the side walls of the first column 14 and the second column 15, and the plurality of second holes 42 are spaced apart on the side walls of the first column 14 and the second column 15. The second holes 42 and the first holes 41 are staggered and arranged on different sides of the first column 14 and the second column 15. The connecting members pass through the first holes 41 or the second holes 42 to fixedly connect the first column 14 and the second column 15. The spacing and size of the first holes 41 and the second holes 42 can be determined according to the actual situation of the project and are not specifically limited in this document. The first holes 41 and the second holes 42 are opened on different sides of the first column 14 and the second column 15. This ensures that the first column 14 and the second column 15 do not lose strength due to the continuous opening of the holes, thereby ensuring the overall strength of the column 11.

[0034] like Figure 3 As shown, in a specific embodiment, the connecting member includes a bolt 43, a nut 44, a first washer 45, and a second washer 46. The bolt 43 passes through the first hole 41 or the second hole 42. The first washer 45 and the second washer 46 are sleeved on the bolt 43 and fixed to the outer wall of the second column 15 via the nut 44. Generally speaking, the surface area of ​​the first washer 45 can be larger than the surface area of ​​the second washer 46. The method of connecting the first column 14 and the second column 15 through the connecting member can ensure the adjustability and stability of the column 11. The method of connecting by bolts 43 and nuts 44 eliminates the need for welding, thereby effectively avoiding the risk of fire caused by welding.

[0035] In one usage of the photovoltaic support structure, after the hydraulic support unit 3 is fixed and stabilized, the column adjustment unit 4 on the column 11 can be removed, and then the first column 14 can be vertically adjusted. After the purlins 12 of the support frame 1 are on the same horizontal line, the column adjustment unit 4 can be reinstalled. After the adjustment is completed, the hydraulic support unit 3 can be removed.

[0036] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
