[0038] The offshore photovoltaic large-span truss cable bridge comprises a plurality of foundation piles 1, support frames 2, and protective frames 3, the plurality of foundation piles 1 are fixed on the sea surface; the support frames 2 are fixed on the foundation piles 1; the protective frames 3 are connected to one side of the support frames 2 away from the foundation piles 1, and the protective frames 3 and the support frames 2 form a protective space; wherein the support frames 2 comprise a plurality of support main bars 21 and a plurality of support auxiliary bars 22, the plurality of support main bars 21 extend along a first direction X and are spaced apart along a second direction Y, the first direction X and the second direction Y intersect, for example, the first direction X and the second direction Y can be perpendicular; the support auxiliary bars 22 are fixed between adjacent two support main bars 21, and the plurality of support auxiliary bars 22 are distributed along the extension direction of the support main bars 21; wherein the cross-sectional area of the support main bars 21 is greater than the cross-sectional area of the support auxiliary bars 22.

[0039] In the offshore photovoltaic large-span truss cable bridge provided by the example embodiment, the protective space formed by the cable bridge can be used to support the cable, and at the same time, the staff can walk in the protective space to install and maintain the cable. In addition, the support frame 2 is composed of a plurality of support main bars 21 and a plurality of support auxiliary bars 22, the plurality of support main bars 21 and the plurality of support auxiliary bars 22 can form a grid structure to support the cable and for the staff to walk, in addition, the support main bars 21 with larger cross-sectional area can improve the overall strength of the cable bridge, and the support auxiliary bars 22 with smaller cross-sectional area can reduce the load of the support frame 2 on the foundation pile 1.

[0040] It should be noted that the cross-sectional area of structure A is the cross-sectional area perpendicular to the extension direction of structure A.

[0041] In the example embodiment, as shown inFigures 1-2 As shown in the figure, the support main bars 21 are fixed on the foundation piles 1, and the protective frame 3 is fixed on the support main bars 21. The support main bars 21 have high strength. In the example, the support main bars 21 are fixed on the foundation piles 1, and the protective frame 3 is fixed on the support main bars 21, so that the overall strength of the cable bridge can be improved.

[0042] In the example, as shown in the figure, Figures 1-2 As shown in the figure, the support frame 2 further comprises a plurality of reinforcing members 23, which are connected between two adjacent support main bars 21, and the reinforcing members 23 and the two adjacent support main bars 21 form a plurality of triangular structures. The triangular structures formed by the reinforcing members 23 and the two adjacent support main bars 21 can improve the structural stability of the support frame 2.

[0043] In the example, as shown in the figure, Figures 1-2 As shown in the figure, the support main bars 21 are in the form of channel steel, and the support auxiliary bars 22 are in the form of tubes. The channel steel has high strength, and the tube has a smooth surface, so that the risk of scratching the cable can be reduced.

[0044] In the example, as shown in the figure, Figures 1-2 As shown in the figure, the foundation piles 1 are supported at both ends of the support frame 2 in the extension direction thereof. This arrangement can provide stable support for the support frame 2 with fewer foundation piles 1, wherein two foundation piles 1 can be arranged at the two ends of the support frame 2, respectively.

[0045] In the example, as shown in the figure, Figures 1-2 As shown in the figure, the foundation piles 1 are supported at both ends of each support main bar 21. For example, in the example, the support frame 2 comprises two support main bars 21, and the foundation piles 1 are supported at both ends of each support main bar 21.

[0046] In the example, as shown in the figure, Figures 1-2 As shown in the figure, the protective frame 3 comprises two protective fences 31 and a protective top 32.

The protective top 32 is fixed on the two protective fences 31, and the protective top 32 and the support frame 2 are arranged opposite and spaced apart. The protective space is formed between the protective top 32, the two protective fences 31, and the support frame 2. The two protective fences 31 and the protective top 32 can provide all-round protection for the cables and the workers in the protective space.

The guard main rib 311 with a larger cross-sectional area plays a main supporting role, and the guard auxiliary rib 312 and the guard main rib 311 form a grid structure to further protect the cables and the workers. Similarly, the plurality of guard top ribs 321 and the guard main rib 311 can also form a grid structure.

[0048] In the example embodiment, as shown in the drawings, the guard main rib 311 and the guard auxiliary rib 312 form a triangular structure. The triangular structure is more stable, thereby improving the overall strength of the cable bridge. Figures 1-2 In the example embodiment, as shown in the drawings, the guard main rib 311 and the guard auxiliary rib 312 form a triangular structure. The triangular structure is more stable, thereby improving the overall strength of the cable bridge.
