Some embodiments of the application disclose a flexible photovoltaic bracket comprising two end bracket assemblies, a cable truss and a wind resistant truss 6.

The two end bracket assemblies are arranged opposite. The end support assembly is fixed on the ground foundation, the ground foundation can adopt a tubular pile or other forms of tensile foundations, and the stability of the flexible photovoltaic support in ground installation is guaranteed.

The number of the cable trusses is multiple, and the multiple cable trusses are arranged side by side along the length direction perpendicular to the upper cable 2. The cable truss is used for connecting the photovoltaic module and is used as a main stress system for supporting the photovoltaic module.

In some embodiments of the application, the cable truss includes an upper cable 2, a lower cable 3, a stabilizing cable 4, and a Y-shaped wind resistant bracket 5. The number of the upper rope 2, the lower rope 3 and the stabilizing rope 4 is one, and the number of the Y-shaped wind-resistant brackets 5 is at least one.

The two ends of the upper cable 2 are respectively connected with the two end bracket assemblies, the two ends of the lower cable 3 are respectively connected with the two end bracket assemblies, and the two ends of the stabilizing cable 4 are respectively connected with the two end bracket assemblies, or the upper cable 2, the lower cable 3 and the stabilizing cable 4 are positioned between the two end bracket assemblies and are all fixed on the two end bracket assemblies.

The upper cable 2 and the lower cable 3 are connected with the photovoltaic module, act as load-bearing cables, support the weight of the photovoltaic module and transmit the weight of the photovoltaic module to the end bracket module.

The stabilizing cable 4 is arranged between the upper cable 2 and the lower cable 3 with an original sag, wherein the original sag is determined according to the stress requirement. The stability of the flexible photovoltaic bracket is improved by matching the stabilizing rope 4 with the upper rope 2 and the lower rope 3, and the capability of the flexible photovoltaic bracket for resisting external force is improved.

Preferably, only one row of Y-shaped wind-resistant brackets 5 is arranged along the length direction of the upper cable 2, and the weight of the flexible photovoltaic bracket is reduced on the premise of ensuring the fixing of the upper cable 2, the lower cable 3 and the stabilizing cable 4.

Since the upper rope 2, the lower rope 3 and the stabilizer rope 4 are identical in length direction, the length direction will be described with reference to the upper rope 2.

In the embodiment in which the number of the Y-shaped wind-resistant brackets 5 is one, the plane of the Y-shaped wind-resistant brackets 5 is perpendicular to the length direction of the upper cable 2.

In the embodiment with a plurality of Y-shaped wind-resistant brackets 5, the plurality of Y-shaped wind-resistant brackets 5 are arranged along the length direction of the upper cable 2, and the plane of the Y-shaped wind-resistant brackets 5 is perpendicular to the length direction of the upper cable 2.

Specifically, the number of the Y-shaped wind-resistant brackets 5 is related to the span of the flexible photovoltaic brackets, the larger the span of the flexible photovoltaic brackets is, the more the number of the Y-shaped wind-resistant brackets 5 is, the smaller the span of the flexible photovoltaic brackets is, and the number of the Y-shaped wind-resistant brackets 5 is relatively smaller.

In the embodiment that the number of the Y-shaped wind-resistant brackets 5 is multiple, the Y-shaped wind-resistant brackets 5 are used for fixing the upper cable 2, the lower cable 3 and the stabilizing cable 4 in a segmented manner, and the more the number of the Y-shaped wind-resistant brackets 5 is included in each cable truss, the stronger the wind-resistant capability of the flexible photovoltaic bracket is, and the more stable the photovoltaic module is supported.

As shown in fig. 2, 5, 6, 7 and 8, the Y-shaped wind-resistant bracket 5 comprises a first inclined rod 51, a second inclined rod 52 and a vertical rod 53, wherein the first inclined rod 51 and the second inclined rod 52 are positioned above the vertical rod 53, the free end of the first inclined rod 51 is provided with an upper cable 2, the free end of the second inclined rod 52 is provided with a lower cable 3, and the free end of the vertical rod 53 is provided with a stabilizing cable 4.

The free end of the first diagonal rod 51 is the end of the first diagonal rod 51 which is not connected to the second diagonal rod 52, and the free end of the second diagonal rod 52 is the end of the second diagonal rod 52 which is not connected to the first diagonal rod 51.

Here, the connection position of the upper cable 2 and the first diagonal member 51 is not limited to the free end of the first diagonal member 51, and may be connected to another position of the first diagonal member 51, and similarly, the connection position of the lower cable 3 and the second diagonal member 52 is not limited to the free end of the second diagonal member 52, may be connected to another position of the second diagonal member 52, and similarly, the stabilizing cable 4 may be connected to any position of the vertical member 53.

The upper cable 2 and the lower cable 3 are fixed with the Y-shaped wind-resistant bracket 5, so that unsynchronized vibration generated by the upper cable 2 and the lower cable 3 in a strong wind environment can be avoided, the stability of connection between the cable truss and the photovoltaic module is ensured, the photovoltaic module is better protected, and the durability and the reliability of the photovoltaic module are improved. The Y-shaped wind-resistant support is connected with the upper cable, the lower cable and the stabilizing cable, so that the upper cable, the lower cable and the stabilizing cable form a whole, vertical load of the photovoltaic module is transmitted to the stabilizing cable through the Y-shaped wind-resistant support, the problems of overlarge plane disturbance degree and poor wind resistance of the flexible photovoltaic support are solved, and the risks of side turning of the cable truss and hidden cracking of the photovoltaic module are reduced.

The photovoltaic module needs to be arranged obliquely, so that a height difference exists between the upper cable 2 and the lower cable 3 connected with the photovoltaic module, specifically, the height of the upper cable 2 is higher than that of the lower cable 3, and the height difference between the upper cable 2 and the lower cable 3 is adjusted according to the inclination requirement of the photovoltaic module.

The distance between the free end of the first diagonal rod 51 and the free end of the second diagonal rod 52 is a preset distance, and the preset distance is the distance between two connecting positions on the photovoltaic module for connecting with the upper cable 2 and the lower cable 3; the inclination angles of the planes of the free ends of the first inclined rod 51 and the second inclined rod 52 are preset inclination angles, and the preset inclination angles are inclination angles of the photovoltaic modules. After the photovoltaic module is determined, the preset inclination angles of the planes of the free ends of the first inclined rod 51 and the second inclined rod 52 and the preset distance between the free ends of the first inclined rod 51 and the free ends of the second inclined rod 52 are determined, and the position of the vertical rod 53 is determined by combining the position of the stabilizing rope 4, namely, the positions of three points of the triangular structure at the upper end of the Y-shaped wind-resistant support 5 are determined, so that the angles among the first inclined rod 51, the second inclined rod 52 and the vertical rod 53 of the Y-shaped wind-resistant support 5 are obtained; according to the installation height of the photovoltaic module, determining the height of a structure of the Y-shaped wind-resistant bracket 5 above the wind-resistant truss 6; the height of the connection structure of the Y-shaped wind-resistant bracket 5 and the wind-resistant truss 6 is determined according to the sag of the stabilizing rope 4.

The height of the wind-resistant truss 6 is equal to the height of the connecting part structure of the Y-shaped wind-resistant bracket 5 and the wind-resistant truss 6.

According to the flexible photovoltaic support disclosed by the application, the supports for fixing the upper cable 2, the lower cable 3 and the stabilizing cable 4 are designed into the Y-shaped wind-resistant support 5, the angles among the first inclined rod 51, the second inclined rod 52 and the vertical rod 53 of the Y-shaped wind-resistant support 5 are determined by the photovoltaic assembly and the stabilizing cable 4 according to the structure of the photovoltaic assembly and the position of the stabilizing cable 4, the customization of the structure of the Y-shaped wind-resistant support 5 above the wind-resistant truss 6 is realized, and the design difficulty of the Y-shaped wind-resistant support 5 is reduced.

The heights of the photovoltaic modules positioned on the same flexible photovoltaic support are equal, and the height of the structure of the Y-shaped wind-resistant support 5 positioned above the wind-resistant truss 6 does not need to be adjusted; the height of the structure of the connection part of the Y-shaped wind-resistant bracket 5 and the wind-resistant truss 6 is adjusted according to the sag of the stabilizing rope 4, and the height of the wind-resistant truss 6 is adjusted along with the connection part. Along the length direction of the upper cable 2, the heights of the wind-resistant trusses 6 in each row are equal, and customization of the wind-resistant trusses 6 and part of the structures of the Y-shaped wind-resistant brackets 5 connected with the wind-resistant trusses 6 can be realized to a certain extent.

The length of the vertical bars is designed according to the wind resistance strength, the tension of the stabilizing rope 4, etc., and the length of the vertical bars 53 of each row is the same along the length direction perpendicular to the upper rope 2.

At least one row of wind-resistant trusses 6 is arranged between two adjacent cable trusses, and each row of wind-resistant trusses 6 is arranged along the length direction of the upper cable 2 and the number of the wind-resistant trusses is equal to that of the Y-shaped wind-resistant brackets 5 of the cable trusses.

The two ends of the wind-resistant truss 6 are respectively connected with the Y-shaped wind-resistant brackets 5 of the two adjacent cable trusses, and the wind-resistant truss 6 provides supporting force for the cable trusses along the length direction vertical to the upper cable 2. The continuous truss system formed by the cooperation of the wind-resistant truss 6 and the cable truss can reduce the shaking of the cable truss, improve the stability and wind resistance of the flexible photovoltaic bracket and reduce the hidden cracking risk of the photovoltaic module.

Preferably, the wind-resistant trusses 6 are in one-to-one correspondence with the Y-shaped wind-resistant supports of the cable trusses, so that the plurality of flexible photovoltaic supports are uniformly stressed cooperatively, the integrity and wind resistance of the flexible photovoltaic supports are improved, the pressure on the upper cable 2 and the lower cable 3 is also reduced to a certain extent, and the extrusion force on the mounting structure is reduced; meanwhile, the cable truss can be restrained, and the cable truss is prevented from being twisted.

The height of the wind resistant truss 6 is determined according to the height of the vertical bars. After the length of the vertical bars 53 is determined, the wind resistant truss corresponding to the position of the vertical bars 53 can be customized and mass-produced.

As shown in fig. 2, 4, 5 and 6, the height of the wind-resistant truss 6 is lower than the height of the free end of the second diagonal member 52, or the height of the wind-resistant truss 6 is lower than the height of the connection position of the second diagonal member 52 and the lower cable 3, and the design can prevent the collision between the photovoltaic module and the wind-resistant truss 6 and protect the photovoltaic module.

The disclosed flexible photovoltaic bracket also includes a middle support frame 9 disposed between the two end bracket assemblies. As shown in fig. 1 and 3, the plane of the middle support frame 9 is parallel to the plane of the Y-shaped wind-resistant support frame 5, and the width of the middle support frame 9 along the length direction perpendicular to the upper cable 2 is equal to the sum of the widths of at least two cable trusses along the length direction perpendicular to the upper cable 2, so that the upper cable 2, the lower cable 3 and the stabilizing cable 4 of a plurality of cable trusses can be supported at the same time.

The lower extreme of middle part support frame 9 is fixed subaerial, and the weight of a plurality of cable trusses that lie in between two tip support frame assemblies can be shared to middle part support frame 9, reduces the atress of tip support frame assembly, improves the stability of flexible photovoltaic support.

As shown in fig. 1 and 3, the cable truss and the wind-resistant truss are in a suspended state and shake along with wind force easily, and the middle support frame 9 fixes the position of the cable truss between the end support assemblies, so that shake of the photovoltaic assembly on the cable truss can be reduced, the risk of overturning the photovoltaic assembly on the cable truss is prevented, and the risk of hidden cracking of the photovoltaic assembly is reduced.

The number of the middle supporting frames 9 is one or more along the length direction of the upper cable 2.

In an embodiment in which the middle support frame 9 is one, the middle support frame 9 divides the space between the two end support frame assemblies into two parts, the Y-shaped wind-resistant supports 5 positioned at both sides of the middle support frame 9 are symmetrically distributed with respect to the middle support frame 9, and the length of the vertical rod positioned between the end support frame assemblies and the middle support frame 9 is changed from short to long to short.

In the embodiment where the number of middle support frames 9 is N (N is greater than or equal to 2), the distances between adjacent middle support frames 9 are equal to ensure that the stress on the cable truss is uniform.

The number of the middle supporting frames 9 can be one or a plurality along the length direction vertical to the upper cable 2.

In the embodiment in which the number of the middle support frames 9 is one along the length direction perpendicular to the upper rope 2, the width of the middle support frames 9 along the length direction perpendicular to the upper rope 2 is equal to the width of the end support frame assembly along the length direction perpendicular to the upper rope 2.

This embodiment can reduce the size of middle part support frame 9, reduces the installation and the transportation degree of difficulty of middle part support frame 9, and can increase and decrease middle part support frame 9 according to actual demand.

The end bracket is not limited to the above-described structure, but may be other structures, and is not particularly limited herein.

The Y-shaped wind-resistant support 5 and the wind-resistant truss 6 are connected in a plurality of ways.

In some embodiments of the application, the Y-shaped wind resistant brackets 5 are bolted to the wind resistant trusses 6. When the connection mode is adopted, the flexible photovoltaic bracket can be assembled on site, and transportation is convenient.

In other embodiments of the present application, the Y-shaped wind resistant brackets 5 are welded to the wind resistant truss 6. The welding can ensure the connection strength of the Y-shaped wind-resistant support 5 and the wind-resistant truss 6, and has simple operation and low cost.

In order to further enhance the strength of the Y-shaped wind-resistant support 5, so that the flexible photovoltaic support can better cope with weather such as wind, snow, rain and the like,

the first diagonal rod 51 and the second diagonal rod 52 of the Y-shaped wind-resistant bracket bear the force generated by the shaking of the upper cable 2 and the lower cable 3, so that the first diagonal rod 51 and the second diagonal rod 52 are easy to deform along with the shaking, and the connection strength of the first diagonal rod 51 and the upper cable 2 and the connection strength of the second diagonal rod 52 and the lower cable 3 are affected.
