[0036] Refer to Figures 3-4 , which is the second embodiment of the present utility model. This embodiment further provides a stabilizing unit 200, which includes a wind-resistant stabilizing module 201 arranged between the load-bearing cables G.

[0042] Further, a plurality of uniformly arranged screw holes 201a-1 of the same size are provided on the surface of the connecting angle steel 201a that is in contact with the inner support angle steel 201d. In different photovoltaic brackets, the angle between the connecting angle steel 201a and the adjusting angle steel 201c is different. Providing a plurality of screw holes 201a-1 of the same size facilitates adjusting the connection position between the inner support angle steel 201d and the connecting angle steel 201a, adapting to different mountain terrain slopes and component installation inclinations, and improving the stability of the wind-resistant stability module 201.

[0043] Further, the inner support angle steel 201d is arranged on the surface where the connecting screw hole 201c-1 is located; the lateral support angle steel 201e is arranged on the other surface of the adjusting angle steel 201c.

[0044] During operation, the components of the wind-resistant stability module 201 are assembled into a whole in advance through connection, including one connecting angle steel 201a, one outer connecting angle steel 201b, two adjusting angle steels 201c, two inner support angle steels 201d, and two lateral support angle steels 201e; four points on the connecting angle steel 201a and the outer connecting angle steel 201b are connected to the load-bearing cable G through the small hoop X; the wind-resistant stability cable 101 with one end fixed is installed on the nearest wind-resistant stability module 201, and the wind-resistant stability cable 101 is connected to the adjusting angle steel 201c through a U-shaped buckle without fastening; the unfixed end of the wind-resistant stability cable 101 is connected to the adjacent wind-resistant stability module 201 without fastening; after the two ends of the wind-resistant stability cable 101 are respectively connected to the wind-resistant stability module 201, a little tension F (1-2 kN) is applied to the wind-resistant stability cable 101 to stretch the wind-resistant stability cable 101 to be approximately straight, and its other end is anchored to the U-shaped bolt at the top of the fixed anchor pile 102a; finally, the middle part of the wind-resistant stability cable 101 is sequentially connected to the corresponding rows of wind-resistant stability modules 201 to complete the installation of the wind-resistant system.

[0045] A stability unit 200 is arranged at the mid-span position of each row of flexible photovoltaic arrays, and each stability unit 200 is connected through a connecting unit 100 to connect the photovoltaic brackets into a whole. The wind load is transmitted to the ground through the fixed modules 102 at both ends of the wind-resistant stability cable 101, thereby improving the wind resistance stability of the mountain flexible photovoltaic bracket structure.

[0046] Embodiment 3

[0047] Referring to Figure 1 、 Figures 4-5 , this is the third embodiment of the present invention. Different from the previous embodiment, this embodiment further provides: when the photovoltaic array is arranged along the contour line (such as Figure 1 ) or perpendicular to the contour line (such as Figure 5) When the connecting unit 100 and the stabilizing unit 200 are always perpendicular to the installation direction of the load-bearing cable G, the inclination angles of the connecting angle steel 201a and the outer connecting angle steel 201b match the layout direction of the load-bearing cable G, which can improve the wind resistance stability of the photovoltaic support, reduce the influence of wind force, and reduce the damage to the photovoltaic array.

[0048] During operation, when the load-bearing cable G is arranged along the contour line direction, the inclination angles of the connecting angle steel 201a and the outer connecting angle steel 201b are the same as the inclination angle of the load-bearing cable G; when the load-bearing cable G is arranged perpendicular to the contour line, the connecting angle steel 201a and the outer connecting angle steel 201b generally remain horizontal. By adjusting the connection position between the inner support angle steel 201d and the connecting angle steel 201a, the inclination angle of the connecting angle steel 201a can be ensured to be the same as the inclination angle of the load-bearing cable G, and thus the inclination angle of the outer connecting angle steel 201b can also be determined, which is beneficial for the photovoltaic module to always maintain the optimal inclination angle and improve the utilization rate of light resources.

[0049] It should be understood that in the development process of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those ordinary technical personnel who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine work of design, manufacturing, and production.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
