In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0051] Referring to Figures 1 to 6 The present embodiment proposes a photovoltaic flexible support, which comprises two edge support members 1, at least two component fixing cables 2, a component bearing cable 3, at least two wind-resistant frames 4, and a ground anchor mechanism 5. The two edge support members 1 are arranged at intervals along a first direction. The at least two component fixing cables 2 are erected on the two edge support members 1 along the first direction, that is, the extension direction of the component fixing cables 2 is consistent with the first direction. All the component fixing cables 2 are arranged in parallel along a second direction perpendicular to the first direction and are respectively located at different height positions to form a bearing surface for bearing photovoltaic components and arranged in an inclined manner. The component bearing cable 3 is erected on the two edge support members 1 along the first direction, that is, the extension direction of the component bearing cable 3 is consistent with the first direction. The at least two wind-resistant frames 4 are uniformly distributed along the first direction. The top of any wind-resistant frame 4 is fixedly connected with all the component fixing cables 2, and the bottom of any wind-resistant frame 4 is fixedly connected with the component bearing cable 3. The ground anchor mechanism 5 is connected with the wind-resistant frame 4 and is used for anchoring the wind-resistant frame 4.

[0052] It can be understood that, under the action of the wind-resistant frame 4, the component fixing cable 2 and the component bearing cable 3 form a stable cable net structure. When wind load acts on the cable net structure, the force is transmitted to the wind-resistant frame 4 through the component fixing cable 2, and then the wind-resistant frame 4 distributes and transmits the force to the component bearing cable 3 and the ground anchor mechanism 5, thereby improving the wind resistance of the photovoltaic flexible support. Since the ground anchor mechanism 5 is connected with the wind-resistant frame 4, the wind load is effectively dispersed and directly introduced into the ground, further inhibiting the cable net structure from generating large amplitude flutter and torsional deformation under wind pressure, thereby improving the dynamic stability and fatigue resistance of the entire photovoltaic flexible support.

[0053] In the embodiment, the wind-resistant frame 4 comprises wind-resistant straight rods 41 and wind-resistant curved rods 42. The wind-resistant straight rods 41 are arranged obliquely along the bearing surface, and all the component fixing cables 2 are fixed to the wind-resistant straight rods 41. The two ends of the wind-resistant curved rods 42 are fixed to the wind-resistant straight rods 41, and the middle part of the wind-resistant curved rods 42 is fixedly connected with the component bearing cables 3. It can be understood that, under the action of the wind-resistant frame 4, the all component fixing cables 2 and the component bearing cables 3 can form a triangular support structure. Due to the triangular characteristic of the triangular support structure, the stability of the cable net structure can be further improved. The all component fixing cables 2 are fixed to the wind-resistant straight rods 41, which can make the all component fixing cables 2 form the bottom side of the triangular support structure, and the component bearing cables 3 form the apex of the triangular support structure. Compared with the triangular support structure formed between the component fixing cables 2 and the component bearing cables 3 by the cooperation of the cable clamp and the plurality of connecting rods, the use of the wind-resistant straight rods 41 and the wind-resistant curved rods 42 can not only save the number of parts and reduce the laying cost of the photovoltaic flexible support, but also facilitate the assembly of the staff.

[0054] The wind-resistant curved rod 42 comprises a first edge connecting rod body 421, a first curved body 422, a second edge connecting rod body 423, a second curved body 424 and a third edge connecting rod body 425 connected in sequence. The first edge connecting rod body 421 and the third edge connecting rod body 425 are attached to the wind-resistant straight rod 41 and are fixed to the wind-resistant straight rod 41 by U-shaped bolts. The second edge connecting rod body 423 is arranged below the wind-resistant straight rod 41 and is fixedly connected with the component bearing cable 3 by U-shaped bolts. It can be understood that the wind-resistant curved rod 42 is obtained by bending a rod body, so as to further reduce the number of parts and facilitate the assembly of the staff. In addition, the first curved body 422 and the second curved body 424 are connected components for connecting the first edge connecting rod body 421, the second edge connecting rod body 423 and the third edge connecting rod body 425. The bending angle thereof can be adjusted according to actual needs, which is not limited herein. The arrangement of the first edge connecting rod body 421 and the third edge connecting rod body 425 can increase the contact surface between them and the wind-resistant straight rod 41, which not only facilitates the installation, but also ensures the connection strength between the wind-resistant curved rod 42 and the wind-resistant straight rod 41. The arrangement of the second edge connecting rod body 423 can provide installation space for the U-shaped bolts, so as to fix the component bearing cable 3 and the third edge connecting rod body 425.

[0055] When the first side connecting rod body 421 is installed to the wind-resistant straight rod 41, first, the U-shaped bolt is passed through the wind-resistant straight rod 41, so that the wind-resistant straight rod 41 and the U-shaped bolt form a passing channel for passing the assembly fixing cable 2, then the U-shaped bolt is passed through the first side connecting rod body 421, and finally the nut matched with the U-shaped bolt is screwed to the U-shaped bolt, so as to realize the installation among the first side connecting rod body 421, the wind-resistant straight rod 41 and the assembly fixing cable 2. In this way, no additional fixing connection structure for fixing the assembly fixing cable 2 is needed, so as to further reduce the number of parts, and after the installation is completed, the U-shaped bolt is perpendicular to the extension direction of the assembly fixing cable 2, that is, perpendicular to the first direction, so as to avoid the loosening of the nut when the wind-resistant straight rod 41 is subjected to wind load.

[0056] It should be noted that the installation steps of the third side connecting rod body 425 are consistent with those of the first side connecting rod body 421, which will not be repeated here.

[0057] In the embodiment, the ground anchor mechanism 5 is provided in multiple numbers, and any ground anchor mechanism 5 is arranged between two adjacent wind-resistant frames 4. It can be understood that for a large-span photovoltaic flexible support, the multiple ground anchor mechanisms 5 are distributed along the first direction to further improve the wind resistance of the photovoltaic flexible support.

[0058] It should be noted that when the edge support 1 is arranged in multiple rows along the second direction, the assembly fixing cable 2 and the assembly load-bearing cable 3 at the periphery are more sensitive to wind load than those at the inside, so when the ground anchor mechanism 5 is arranged, the ground anchor mechanism 5 can be connected with the wind-resistant frame 4 at the periphery, that is, the wind-resistant frames 4 at the outermost two rows are connected. In this way, the laying cost of the photovoltaic flexible support can be reduced.

[0059] Any ground anchor mechanism 5 includes a ground anchor pile 51 and multiple ground anchor cables 52. The ground anchor pile 51 is anchored to a fixed reference, which can be the ground or some other fixed structure, and can be determined according to the actual working condition, which is not limited here. The ground anchor pile 51 is between two adjacent wind-resistant frames 4. One end of each of the multiple ground anchor cables 52 is fixedly connected with the ground anchor pile 51, and the other end is fixedly connected with the corresponding two wind-resistant frames 4. It can be understood that one ground anchor mechanism 5 can simultaneously anchor two wind-resistant frames 4, which not only reduces the laying cost of the photovoltaic flexible support, but also enables the multiple ground anchor cables 52 to form a three-dimensional anchoring structure, so that the wind load can be transmitted and shared between two adjacent wind-resistant frames 4, and then uniformly digested by the ground anchor pile 51, further ensuring the stability of the cable net structure.

[0060] Exemplarily, one ground anchor pile 51 is provided with four ground anchor cables 52, two of which are connected with the wind-resistant straight bars 41 of one of the wind-resistant frames 4, and the other two are connected with the wind-resistant straight bars 41 of another wind-resistant frame 4, so that the four ground anchor cables 52 form a pyramid structure with the ground anchor pile 51 as the top, thereby ensuring the stability of the cable net structure.

[0061] In the embodiment, the edge support 1 comprises an edge vertical bar 11 and an edge support beam 12, the edge vertical bar 11 is fixedly arranged in the vertical direction, the edge support beam 12 is fixed to the edge vertical bar 11, and the length direction of the edge support beam 12 is arranged in the second direction; both ends of the edge support beam 12 in the second direction are provided with a fixing plate 13 for connecting the component fixing cable 2, one of the fixing plates 13 is above the edge support beam 12, and the other fixing plate 13 is below the edge support beam 12. It can be understood that the two fixing plates 13 correspond to the component fixing cables 2 on both sides respectively, and the inclination angle of the bearing surface can be formed by the height difference between the two fixing plates 13, compared with fixing both fixing plates 13 above the support beam, the height of the fixing plate 13 can be reduced in this way, thereby saving the material used by the fixing plate 13. The component fixing cables 2 in the middle are sequentially arranged on the edge support beam 12 to ensure the continuity of the bearing surface.

[0062] For a large-span photovoltaic flexible support, the component fixing cable 2 and the component bearing cable 3 can sag under their own gravity, therefore, in the embodiment, the photovoltaic flexible support further comprises a middle support 6, the middle support 6 is arranged between the two edge supports 1, and the middle support 6 is used to support all the component fixing cables 2, so that any component fixing cable 2 remains horizontally arranged, which can avoid the component fixing cable 2 from sagging, thereby ensuring the stability of the photovoltaic module during installation, in addition, the middle support 6 is also used to support the component bearing cable 3, so that the connection positions between the component bearing cable 3 and the edge support 1 and the connection positions between the component bearing cable 3 and the middle support 6 are at the same horizontal height. Under the action of the wind-resistant frame 4, the middle part of the component bearing cable 3 can maintain a predetermined distance from the component fixing cable 2, thereby making the vertical plane of the cable net structure trapezoidal, to further improve the wind resistance of the cable net structure.

[0063] The middle support 6 comprises a middle vertical bar 61 and a middle support beam 62 fixed to the middle vertical bar 61, and the middle support beam 62 is arranged obliquely, and the inclination angle is consistent with the inclination angle of the bearing surface, so that all the component fixing cables 2 can be fixed parallel to the middle support beam 62.

[0064] The assembly load cable 3 and the assembly fixing cable 2 are arranged behind the two edge supports 1, and can apply a pulling force to any edge support 1 towards the other edge support 1. In order to ensure the stability of the edge support 1, the photovoltaic flexible support further comprises an edge anchoring mechanism 7 connected with the edge support 1 and used for anchoring the edge support 1. It can be understood that the edge anchoring mechanism 7 is located on the side away from the assembly load cable 3, and can apply an acting force opposite to the direction of the pulling force to the edge support 1, so as to ensure the balance of the force of the edge support 1.

[0065] Specifically, the edge anchoring mechanism 7 comprises an edge anchor pile 71 fixed to a fixed reference and an edge anchor cable 72, both ends of the edge anchor cable 72 are connected with the edge anchor pile 71 and the edge support 1 respectively, so as to complete the anchoring of the edge support 1.

[0066] Further, one edge anchor pile 71 and one anchor cable form a group of edge anchoring structures, and the edge anchoring mechanism 7 is provided with a plurality of groups of edge anchoring structures, which are respectively arranged corresponding to the assembly fixing cable 2 and the assembly load cable 3, so as to balance the pulling force applied by each assembly fixing cable 2 and assembly load cable 3 to the edge support 1 respectively, thereby further ensuring the stability of the edge support 1.

[0067] In the embodiment, the edge supports 1 are arranged in multiple rows along the second direction, and the adjacent two rows of edge supports 1 are connected through the edge connecting rod 8. It can be understood that the edge supports 1 in the same column can form a whole under the action of the edge connecting rod 8, thereby further improving the stability of the entire photovoltaic flexible support.

[0068] Among them, both ends of the edge connecting rod 8 are respectively hinged with the corresponding edge support 1. In this way, the edge connecting rod 8 can be adapted to edge supports 1 of different heights, meeting different installation requirements. In addition, there is often a certain assembly gap between the hinge shaft between the edge connecting rod 8 and the edge support 1 and the corresponding hinge hole, so as to further adapt to different installation environments.

[0069] In the embodiment, the photovoltaic flexible support further comprises a stabilizing link 9 and a stabilizing cable 10, the stabilizing link 9 is arranged between two adjacent rows of the wind-resistant frames 4, and the two ends of the stabilizing link 9 are respectively hinged to the corresponding wind-resistant frames 4; the stabilizing cable 10 is arranged along the second direction and below the stabilizing link 9, and the stabilizing cable 10 is used for connecting all the wind-resistant frames 4 in the same column. It can be understood that, under the action of the stabilizing link 9 and the stabilizing cable 10, the wind-resistant frames 4 in the same column can form a whole, so that the wind resistance of the cable net structure can be further improved. In addition, one stabilizing link 9, one wind-resistant straight rod 41 and the stabilizing cable 10 can form a stable triangular support structure again, so that the stability of the cable net structure can be further improved.

[0070] In addition, a plurality of connecting holes are uniformly distributed on the stabilizing link 9, so that appropriate installation positions can be selected according to different installation requirements, so as to further improve the applicability of the photovoltaic flexible support.

[0071] In the embodiment, the photovoltaic flexible support further comprises a plurality of middle connecting rods 110, the two ends of the middle connecting rod 110 are respectively hinged to two adjacent rows of the middle support members 6, so as to adapt to middle support members 6 of different heights and meet different installation requirements. Under the action of the middle connecting rod 110, the middle support members 6 in the same column can form a whole, so that the stability of the entire photovoltaic flexible support can be further improved.

[0072] In addition, the middle connecting rod 110 between the two adjacent rows of the middle support members 6 can be provided with one or more, wherein, since the wind load received by the middle support members 6 at the periphery is more sensitive than the middle support members 6 at the middle, the middle connecting rod 110 between the two middle support members 6 at the periphery can be provided with a plurality of, preferably two, and the plurality of middle support members 6 can be arranged between the two adjacent rows of the middle support members 6 in a cross arrangement, so as to further improve the stability of the photovoltaic flexible support. However, for the two adjacent middle support members 6 in the middle region, a single middle connecting rod 110 can be arranged, so as to reduce the laying cost of the photovoltaic flexible support.

[0073] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present application. It is unnecessary and impossible to enumerate all the implementation modes. Any modification, equivalent substitution and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
