The flexible photovoltaic support structure system in the existing photovoltaic array generally adopts double-cable support (without additional cables and space trusses) and triple-cable support, and the self weight of the structure and the acting force under the wind and snow working condition are resisted by applying prestress on the double cables directly contacted with the photovoltaic module. Because the flexible cable structure is adopted for supporting, the problems of small structural rigidity, large mid-span deflection, weak wind resistance and great possibility of generating large-amplitude vibration appear. In order to solve the above technical problems, in the prior art, a stabilizing cable is often used to connect the cable truss mechanisms in the flexible photovoltaic support into a whole so as to limit the relative displacement and torsion of the cable truss mechanisms. However, the above prior art requires tensioning of the stabilizing cable and the provision of a side anchor mechanism, thereby increasing the production cost. Meanwhile, the arrangement of the stabilizing cable requires that each cable truss mechanism is approximately in a plane, and the middle part of the cable truss mechanism cannot be fluctuated, so that the application scene is limited.
The embodiment of the application provides a photovoltaic array, which is essentially a photoelectric conversion device, and can be installed in various open-place environments such as companies, schools, factories or the field, so that solar energy is converted into electric energy, and the application of renewable energy of people is improved.

The trusses 114 are spaced apart in a first direction. The high-level cable 111, the low-level cable 112 and the additional cable 113 all extend in a first direction and are connected to the support assembly. As shown in fig. 3, the truss 114 includes a first frame body 1141, a second frame body 1142, and a mounting frame 1143. Photovoltaic module locates mounting bracket 1143. One end of the first housing 1141 and one end of the second housing 1142 are connected to the mounting bracket 1143, respectively. The high-position cable 111 and the low-position cable 112 are mounted on the mounting bracket 1143. The number of the first link frames 20 is plural. Each first connecting frame 20 extends in the second direction and connects at least two of the cable trusses 11 together. The number of the second link frames 30 is plural. Each second connecting frame 30 extends in the second direction and connects at least two of the cable trusses 11 together. The second connecting frames 30 are correspondingly positioned under the first connecting frames 20 to form a planar supporting structure. In this embodiment, the high-position rope 111, the low-position rope 112, and the additional rope 113 are all steel strands. The additional rope 113 is provided to the second link frame 30.

In summary, the embodiment of the utility model has the following beneficial effects: the flexible photovoltaic support is applied to a photovoltaic array, so that the photovoltaic array has excellent photoelectric conversion efficiency, and the flexible photovoltaic support has the effects of low cost and capability of adapting to more application scenes. Specifically, the flexible photovoltaic support comprises a plurality of cable truss mechanisms 11 extending along a first direction and sequentially arranged on each supporting assembly, and a plurality of first connecting frames 20 and second connecting frames 30 extending along a second direction, wherein each first connecting frame 20 at least connects two cable truss mechanisms 11 into a whole, and each second connecting frame 30 at least connects two cable truss mechanisms 11 into a whole. Thus, the cable truss mechanism 11 can be supported by the first connecting frame 20 and the second connecting frame 30 in a direction perpendicular to the extending direction of the cable truss mechanism, and meanwhile, the first connecting frame 20 and the second connecting frame 30 do not need to be tensioned and are provided with side anchor mechanisms, so that the production cost is greatly saved. Further, the lengths of the first connecting frame 20 and the second connecting frame 30 can be designed according to the topographic requirements of the application scene, that is, the lengths of the first connecting frame 20 and the second connecting frame 30 are designed along the second direction to adapt to the fluctuation of the terrain, so that the application scene of the photovoltaic array is expanded.
Each first connecting frame 20 connects at least two cable truss mechanisms 11 into a whole, and each second connecting frame 30 connects at least two cable truss mechanisms 11 into a whole, specifically, when the terrain is flat, the first connecting frame 20 and the second connecting frame 30 can be a section. When the terrain is fluctuated, the first connecting frame 20 and the second connecting frame 30 can be used for adapting to the fluctuation of the terrain.
Further, the first connecting frame 20 can provide support for one of the high-position cable 111, the low-position cable 112 and the truss 114, thereby realizing integral support for the cable truss mechanism 11. In this embodiment, please refer to fig. 3, the first connecting frame 20 is connected to the first frame 1141 and the second frame 1142 respectively. The connection point of the first coupling bracket 20 and the first bracket body 1141 is located between the high-level cable 111 and the additional cable 113. The connection point of the first coupling bracket 20 and the second bracket body 1142 is located between the lower cable 112 and the additional cable 113. This ensures the connection stability of the first connecting frame 20 and the cable truss structure 11.
In one embodiment, with continued reference to fig. 3, an end of the first housing 1141 and an end of the second housing 1142 are hinged to the mounting bracket 1143, respectively. The first connecting bracket 20 is hinged to the first bracket body 1141 and the second bracket body 1142, respectively. The other end of the first frame body 1141 and the other end of the second frame body 1142 are spaced apart and hinged to the second connection frame 30, respectively. So make first support body 1141, second support body 1142, mounting bracket 1143, first link 20 and second link 30 constitute two parallelograms, make things convenient for high-order cable 111 and low-order cable 112 to adjust the inclination of mounting bracket 1143 to the angle of convenient adjustment photovoltaic module, with the sun that can be better faces.

Therefore, the high-position cable 111 and the low-position cable 112 are located at the relatively far ends of the mounting frame 1143, so that the driving force of the high-position cable 111 and the low-position cable 112 can be better transmitted to the mounting frame 1143, and the angle of the high-position cable and the angle of the low-position cable can be conveniently adjusted.
In one embodiment, referring to fig. 4-6, the highcable 111 is mounted to the mounting bracket 1143 via the first U-shaped member 115. The lower cable 112 is attached to the mounting bracket 1143 via the second U-shaped member 116. The additional cable 113 is provided to the second link frame 30 through a third U-shaped member 117. The first U-shaped element 115, the second U-shaped element 116 and the third U-shaped element 117 are arranged to connect the high-level cable 111, the low-level cable 112 and the additional cable 113 to the mounting bracket 1143 and the second connecting bracket 30 while maintaining the same extending direction.
