A support mechanism is arranged on one side of the triangular brace 2, and a connecting mechanism is arranged on one side of the main cable 1;

[0028] The support mechanism includes the second main connecting plate 201, the middle steel column 202, the first U-shaped section strut 203, the secondary connecting plate 204, the end steel column 205 and the second U-shaped section strut 206. The second main connecting plate 201 is arranged at the bottom of the triangular brace 2. The first U-shaped section strut 203 is fixedly connected to the bottom of the second main connecting plate 201. The right side of the second main connecting plate 201 is connected to the stabilizing cable 101, and they are bolted between the second main connecting plate 201 and the stabilizing cable 101. The middle steel column 202 is arranged between the second main connecting plate 201 and the first U-shaped section strut 203. The secondary connecting plate 204 is arranged on one side of the top of the triangular brace 2. The bottom of the secondary connecting plate 204 is connected to the stay cable 102, and they are bolted between the secondary connecting plate 204 and the stay cable 102. The second U-shaped section strut 206 is fixedly connected to the top of the triangular brace 2. The end steel column 205 is arranged between the triangular brace 2 and the second U-shaped section strut 206. The first U-shaped section strut 203 and the middle steel column 202 connect the triangular brace 2 together by bolts and wire rope clips, and then the top of the right side of the triangular brace 2 is connected to the photovoltaic module 3 by the second U-shaped section strut 206 and the end steel column 205 by bolts and wire rope clips to provide preliminary support for the whole. The orientation of the main cable 1 and the stabilizing cable 101 is fully utilized to form a triangle. According to the stability characteristics of the triangle, connecting plates are added at the vertices of the triangle and connected to the main cable 1 and the stabilizing cable 101 through U-shaped clamps, greatly strengthening the synergy between the main cable 1 and the stabilizing cable 101.

[0029] The triangular brace 2 is located at one-third of the span of the main cable 1. Two triangular braces 2 are arranged between each span of the main cables. The corresponding triangular braces 2 form a triangular rigid connection system through U-shaped section struts with certain stiffness, greatly reducing the out-of-plane instability phenomenon caused by too large a span between the flexibles and ensuring that the distance between the photovoltaic modules 3 in adjacent two spans remains unchanged under the action of wind load.

[0030] Embodiment 2:

[0031] On the basis of Embodiment 1, the connecting mechanism includes the stabilizing cable 101, the stay cable 102, the first main connecting plate 103, the first bolt 104 and the second bolt 105. The first main connecting plate 103 is arranged on the left side of the main cable 1. The stay cable 102 and the first main connecting plate 103 are fixedly connected to the left side of the first main connecting plate 103. The first bolt 104 and the second bolt 105 are respectively arranged on the left and right sides of the first main connecting plate 103. The first bolt 104 penetrates through the stabilizing cable 101, the stay cable 102 and the first main connecting plate 103 to connect the three of them. The second bolt 105 penetrates through the first main connecting plate 103 and the main cable 1, and they are connected by the second bolt 105. The first main connecting plate 103 is used to connect the main cable 1, the stabilizing cable 101 and the stay cable 102 in sequence through the first bolt 104 and the second bolt 105, and the whole initially reaches a balanced state.

[0032] A photovoltaic module 3 is provided at the top of the triangular brace 2. The triangular braces 2 around the photovoltaic array are connected to the ground anchors through wind-resistant cables, making the entire system not easily deformed.

[0033] Working principle:

[0034] First, through the provided connecting mechanism, the main cable 1, the stabilizing cable 101, and the stay cable 102 are sequentially connected by the main connecting plate one 103 through bolts one 104 and bolts two 105, and the whole initially reaches a balanced state.

[0035] Furthermore, through the provided supporting mechanism, the U-shaped cross-section strut one 203 and the middle steel column 202 connect the triangular brace 2 together through bolts and wire rope clips, and then connect the photovoltaic module 3 to the top on the right side of the triangular brace 2 through the U-shaped cross-section strut two 206 and the end steel column 205 through bolts and wire rope clips for initial support of the whole.

[0036] Furthermore, the main connecting plate two 201 is fixed to the stabilizing cable 101 using bolts, and the secondary connecting plate 204 and the stay cable 102 are fixed using bolts.

[0037] Furthermore, the triangular braces 2 around the photovoltaic array are connected to the ground anchors through wind-resistant cables, making the entire system not easily deformed.

[0038] Furthermore, the system makes full use of the orientations of the main cable 1 and the stabilizing cable 101 to form a triangle. According to the stable characteristics of the triangle, connecting plates are added at the vertices of the triangle and connected to the main cable 1 and the stabilizing cable 101 through U-shaped clips, greatly strengthening the synergistic effect between the main cable 1 and the stabilizing cable 101.

[0039] Even further, the triangular brace 2 is located at one-third of the span of the main cable 1. Two triangular braces 2 are provided between each span of the main cables. The corresponding triangular braces 2 form a triangular rigid connection system through U-shaped cross-section struts with a certain stiffness, greatly reducing the out-of-plane instability phenomenon caused by too large a span between the flexibilities and ensuring that the spacing between the photovoltaic modules 3 in adjacent two spans remains unchanged under the action of wind loads.
