Description

Technical Field

[0001] The embodiments of the present application relate to the field of photovoltaic technology, and in particular to a photovoltaic support assembly and a photovoltaic system. Background Art

[0002] With the steady advancement of the country's "dual carbon strategy", new energy power generation systems represented by photovoltaic systems have developed rapidly. As the main load-bearing components of photovoltaic modules, photovoltaic brackets play an important role in ensuring the safety and stability of photovoltaic systems. The flexible photovoltaic brackets used in existing photovoltaic systems often use columns to support two cables as the main load-bearing components. The ability of photovoltaic brackets to resist external forces such as horizontal wind is relatively weak. Utility Model Content

[0003] In view of this, the present application provides a photovoltaic support assembly to improve the wind resistance of the photovoltaic support assembly.

[0004] In the first aspect, the present application provides a photovoltaic support assembly, which includes a plurality of brackets, a plurality of first cables, a plurality of second cables, and auxiliary support members. The first cables extend along the first direction, and every two first cables are arranged in a group along the second direction, and are respectively distributed on the first layer and the second layer along the vertical direction, and every two first cables are erected between two brackets arranged along the first direction; every two auxiliary support members are arranged along the second direction; the second cables extend along the second direction, and every two second cables are erected between two auxiliary support members, and are respectively located on the first layer and the second layer along the vertical direction; each second cable located on the first layer intersects with the plurality of first cables and is fixedly connected at the intersection; each second cable located on the second layer intersects with the plurality of first cables and is fixedly connected at the intersection.

[0005] In the above photovoltaic support assembly, the middle part of the first cable between the brackets intersects with and is fixedly connected to the second cable, and can be supported by the second cable. The auxiliary support member tightens and fixes the second cable to improve the wind resistance of the middle part of the first cable.

[0006] In a possible implementation, the auxiliary support member includes two second frames arranged along the second direction, and the tops of the two second frames are connected and are respectively inclined relative to the vertical direction.

[0007] In the above embodiment, the second cable provides a supporting force for the first cable along the vertical direction, which can effectively resist wind suction and wind torsion. The second cable transmits the horizontal wind load force to the two second frames, which are respectively inclined relative to the vertical direction, so that the second frames provide the second cable with a supporting force perpendicular to the vertical direction or inclined relative to the vertical direction. The supporting force can balance part of the external force (such as horizontal wind force parallel to the second direction), thereby improving the performance of resisting horizontal wind force and improving the wind resistance of the photovoltaic support assembly.

[0008] In a possible implementation, the two second cables located at the first layer and the second layer are connected to a second frame located inside the photovoltaic support assembly in the auxiliary support member.

[0009] In the above embodiment, along the second direction, the distance between the two second frames located inside the photovoltaic support assembly is smaller than the distance between the two second frames located outside the photovoltaic support assembly. The second cable is connected to the two second frames with a smaller distance, which can save the material of the second cable and reduce the cost of the photovoltaic support assembly. In addition, when the second cable is installed on the second frame located inside the photovoltaic support assembly, it will not be blocked by the other second frame, which makes the installation of the second cable convenient.

[0010] In a possible embodiment, the photovoltaic support assembly also includes a first support member and a second support member; the first support member is fixed to the intersection of the first cable of the first layer and the second cable of the first layer; the second support member is fixed to the intersection of the first cable of the first layer and the second cable of the second layer.

[0011] In the above embodiment, the second cable is connected to the first cable at the intersection, and the second cable can tighten the first cable. The first support member and the second support member respectively support and fix the second cable to provide a supporting force for the first cable in the vertical direction, so as to improve the wind resistance performance of the photovoltaic support assembly, such as wind suction resistance and wind torsion resistance.

[0012] In a possible embodiment, the photovoltaic support assembly also includes a plurality of fixing rods, the fixing rods including a first end and a second end; the second cable located on the first layer is fixedly connected to the first end of the fixing rod at the intersection with the first cable; the second cable located on the second layer is fixedly connected to the second end of the fixing rod at the intersection with the first cable.

[0013] In the above embodiment, the fixing rod is a hard structure and is not easy to deform. The fixing rod is connected to the intersection of the first cable and the second cable of the first layer and between the first cable and the second cable of the second layer, thereby improving the position stability between the two intersections. On the basis of the auxiliary support member tightening and supporting the first cable for the second cable, the fixing rod further improves the tensioning effect between the second cable and the first cable, thereby reducing the risk of the flexible first cable and the second cable deforming and displacing when subjected to external forces such as wind, thereby causing the photovoltaic module to flip or twist.

[0014] In a possible embodiment, the bracket includes two first sub-brackets arranged at intervals along the second direction, and a first crossbeam connected between the two first sub-brackets; the first sub-bracket is in an eight-shaped shape, including two first frame bodies arranged along the first direction, the two first frame bodies are connected, and are respectively inclined relative to the vertical direction.

[0015] In the above embodiment, the two first frames of the first sub-bracket are respectively inclined relative to the vertical direction, so that the first frame provides a supporting force in a direction perpendicular to the vertical direction or inclined relative to the vertical direction, thereby being able to offset part of the external force in the horizontal direction. For example, when the bracket resists the wind force in the first direction, the first crossbeam is supported between the two first sub-brackets, and the four first frames and at least one first crossbeam in the bracket jointly resist the wind force, so that the bracket has a high performance in resisting wind force relative to a single column extending in the vertical direction, including improved performance in resisting horizontal wind force. When the bracket resists the wind force in the second direction, the inclination of the first frame can offset at least part of the horizontal wind force, thereby improving the performance of the bracket in resisting horizontal wind force, and the four first frames and at least one first crossbeam of the bracket resist the wind force at the same time, so that the bracket has a high performance in resisting wind force relative to a single column extending in the vertical direction.

[0016] In a possible implementation manner, the first crossbeam is connected to the tops of the two first sub-supports.

[0017] In the above embodiment, the two first frames are connected at the top, the first crossbeam is connected to the top of the two frames, the first cable is connected to the top of the first sub-bracket, and the assembly of the first sub-bracket is completed at the top of the two first frames. The connection between the first cable and the first sub-bracket is also located at the top of the first frame, which is conducive to improving the assembly efficiency of the photovoltaic support assembly.

[0018] In a second aspect, the present application provides a photovoltaic system, which includes a photovoltaic support assembly and a plurality of photovoltaic assemblies, wherein the photovoltaic support assembly includes a plurality of brackets, a plurality of first cables, a plurality of second cables, and an auxiliary support member. The first cable extends along a first direction, and each two first cables are arranged in a group along a second direction, and are respectively distributed on a first layer and a second layer along a vertical direction, and each two first cables are erected between two brackets arranged along the first direction; each two auxiliary support members are arranged along the second direction; the second cable extends along the second direction, and each two second cables are erected between two auxiliary support members, and are respectively located on a first layer and a second layer along a vertical direction; each second cable located on the first layer intersects with a plurality of first cables and is fixedly connected at the intersection; each second cable located on the second layer intersects with a plurality of first cables and is fixedly connected at the intersection. The photovoltaic assembly is connected to the two first cables located on the first layer and the second layer.

[0019] In the above photovoltaic system, the middle part of the first cable located between the brackets intersects with and is fixedly connected to the second cable, and can be supported by the second cable. The auxiliary support member tightens and fixes the second cable to improve the wind resistance of the middle part of the first cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] In order to further illustrate the technical means and effects adopted by the present application to achieve the intended application purpose, the following is combined with the drawings and implementation methods. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0061] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0062] Please also see Figure 1 and Figure 2 One embodiment of the present application provides a photovoltaic system 200 and a photovoltaic support assembly 100. The photovoltaic system 200 includes a photovoltaic support assembly 100 and a plurality of photovoltaic assemblies 201. The photovoltaic assemblies 201 are used to convert light energy into electrical energy. The photovoltaic support assembly 100 is used to support the photovoltaic assemblies 201 so that the photovoltaic assemblies 201 are set up on a platform (not shown), for example, on a mountain, farmland, pond, or sea.

[0063] The photovoltaic support assembly 100 includes a plurality of brackets 10, a plurality of first cables 20, a plurality of auxiliary support members 30, and a plurality of second cables 50. The plurality of brackets 10 support the plurality of first cables 20, so that each two adjacent first cables 20 are located on the first layer P1 and the second layer P2. The first layer P1 and the second layer P2 have different heights. The photovoltaic assembly 201 is installed on the two adjacent first cables 20 located on the first layer P1 and the second layer P2, so that the photovoltaic assembly 201 is tilted relative to the platform, so that the photovoltaic assembly 201 faces the direction of strong light or prolongs the light exposure time of the photovoltaic assembly 201, etc., so as to facilitate the light conversion efficiency.

[0064] The first cables 20 extend along the first direction Y. Every two brackets 10 form a group, which are arranged along the first direction Y and are used to support two adjacent first cables 20 located at the first layer P1 and the second layer P2.

[0065] The second cables 50 extend along the second direction X. Every two auxiliary support members 30 are arranged along the second direction X and are used to support two adjacent second cables 50 located at the first layer P1 and the second layer P2.

[0066] In one embodiment, the number of the brackets 10 is eight, and every four brackets 10 are arranged in a row at intervals along the second direction X. It can be understood that in other embodiments, the number of the brackets 10 may also be four, six, ten, twelve, fourteen, ... fifty, or other numbers.

[0067] In one embodiment, the second direction X is perpendicular to the first direction Y, the second direction X is the north-south direction, and the first direction Y is the east-west direction, but is not limited thereto. For example, in other embodiments, the second direction X and the first direction Y may also be two directions that intersect at an acute angle or an obtuse angle, the second direction X may be inclined at an angle relative to the north-south direction, and the first direction Y may be inclined at an angle relative to the east-west direction. The second direction X and the first direction Y may be set differently depending on the region where the platform is located and the orientation of the photovoltaic module 201.

[0068] The support 10 includes two first sub-supports 11 and a first crossbeam 13. The two first sub-supports 11 are arranged at intervals along the second direction X. The first sub-support 11 includes two first frames 111. The two first frames 111 are arranged along the second direction X and connected at the top. The two first frames 111 are respectively inclined relative to the vertical direction Z, so that the first sub-support 11 is roughly in an inverted V shape. The first crossbeam 13 is connected between the two first sub-supports 11. The auxiliary support member 30 is arranged between the two supports 10 along the first direction Y and supports each first cable 20.

[0069] It is understandable that in other embodiments, the bracket 10 may also be other structures such as a column.

[0070] In one embodiment, the two first frames 111 of the bracket 10 are connected to the platform, but the present invention is not limited thereto.

[0071] For example, in other embodiments, the bracket 10 and the platform may also be unconnected and relatively fixed by other means. For example, the bracket 10 is supported in a groove (not shown) on the platform, and the groove wall abuts against the peripheral side of the first frame 111 to reduce the risk of the first frame 111 tipping, thereby achieving the fixation of the first frame 111 relative to the platform.

[0072] The two first sub-supports 11 of the support 10 are respectively connected to the two first cables 20, and the two first frames 111 of the first sub-supports 11 are respectively inclined relative to the vertical direction Z, so that the first frames 111 are supported by the platform in a direction perpendicular to the vertical direction Z or inclined relative to the vertical direction Z, thereby being able to offset a part of the external force in the horizontal direction (for example, the horizontal wind force parallel to the first direction Y). For example, when the support 10 resists the wind force in the second direction X, the first crossbeam 13 is supported between the two first sub-supports 11, and the four first frames 111 in the support 10 1 and at least one first cross beam 13 jointly resist wind force, so that the support 10 has a higher performance of resisting wind force relative to a single column extending along the vertical direction Z, including improved performance of resisting horizontal wind force; when the support 10 resists wind force in the first direction Y, the first frame body 111 is tilted to offset at least part of the horizontal wind force, thereby improving the performance of the support 10 resisting horizontal wind force, and the four first frames 111 and at least one first cross beam 13 of the support 10 resist wind force at the same time, so that the support 10 has a higher performance of resisting wind force relative to a single column extending along the vertical direction Z.

[0073] In one embodiment, please continue to refer to Figure 3The two ends of the first crossbeam 13 are connected to the tops of the two first sub-supports 11, that is, connected to the tops of the two first frames 111 of each first sub-support 11. Two adjacent first cables 20 are connected to the tops of the two first sub-supports 11. The two first sub-supports 11 have different heights so as to support the two first cables 20 located on the first layer P1 and the second layer P2 respectively.

[0074] The first cross beam 13 is connected between the two first sub-supports 11 , which is beneficial to the stability of the support 10 .

[0075] The two first frames 111 are connected at the top, the first crossbeam 13 is connected to the top of the two frames, the first cable 20 is connected to the top of the first sub-bracket 11 or the first crossbeam 13, and the assembly operation of the first sub-bracket 11 is completed at the top of the two first frames 111; and the connection operation between the first cable 20 and the first sub-bracket 11 is also located at the top of the first frame 111, which is beneficial to improving the assembly efficiency of the photovoltaic support assembly 100.

[0076] It can be understood that the number of the first cross beam 13 is not limited to one. For example, in another embodiment, Figure 4 As shown, there are two first beams 13 in the bracket 10b, and the two first beams 13 are spaced and symmetrically connected between the two first sub-brackets 11 along the first direction Y, and the first beams 13 are connected to the side wall of the first frame 111. The two first beams 13 improve the overall strength of the bracket 10b, which is conducive to improving the wind resistance performance.

[0077] See also Figure 2 In one embodiment, each second cable 50 of the first layer P1 sequentially intersects with the plurality of first cables 20 of the first layer P1 along the second direction X, and are fixedly connected at the intersections, so that the second cables 50 of the first layer P1 tighten the plurality of first cables 20 of the first layer P1 arranged along the second direction X; each second cable 50 of the second layer P2 sequentially intersects with the plurality of first cables 20 of the second layer P2 along the second direction X, and are fixedly connected at the intersections, so that the second cables 50 of the second layer P2 tighten the plurality of first cables 20 of the second layer P2 arranged along the second direction X. The middle portion of the first cable 20 located between the brackets 10 is supported by the second cable 50 to improve the wind resistance of the middle portion of the first cable 20.

[0078] In one embodiment, the first cable 20 and the second cable 50 are connected via a connecting member 80 .

[0079] It can be understood that in other embodiments, the number of auxiliary support members 30 can also be two, four, eight, ten, twelve... twenty, thirty or other numbers.

[0080] The first cable 20 and the second cable 50 may be cable structures such as steel strands and steel wire ropes. In one embodiment, the strength of the first cable 20 is generally higher than that of the second cable 50. The first cable 20 is a steel strand and the second cable 50 is a steel wire rope, but the present invention is not limited thereto. The materials of the first cable 20 and the second cable 50 may be set according to the load-bearing requirements, environmental wind force, etc.

[0081] In one embodiment, the auxiliary support member 30 is substantially in an eight-shaped shape. The auxiliary support member 30 includes two second frames 311. The two second frames 311 are arranged along the second direction X and connected at the top. The two second frames 311 are inclined relative to the vertical direction Z respectively.

[0082] The second cable 50 provides a supporting force for the first cable 20 along the vertical direction Z, which can effectively resist wind suction and wind torsion. The second cable 50 transmits the horizontal wind load force to the auxiliary support member 30. The two second frames 311 of the auxiliary support member 30 are respectively inclined relative to the vertical direction Z, so that the second frame 311 provides the second cable 50 with a supporting force perpendicular to the vertical direction Z or inclined relative to the vertical direction Z. The supporting force can balance part of the external force (for example, the horizontal wind force parallel to the second direction X), thereby improving the performance of the auxiliary support member 30 in resisting horizontal wind force, and improving the overall performance of the photovoltaic support assembly 100 in resisting wind suction, wind torsion and horizontal wind load force.

[0083] The wind suction resistance performance refers to the ability of the photovoltaic support assembly 100 to resist the photovoltaic assembly 201 being overturned by wind, and the wind torsion resistance performance refers to the ability of the photovoltaic support assembly 100 to resist the deflection of the photovoltaic assembly 201 relative to the plurality of first cables 20 .

[0084] In one embodiment, the two second cables 50 located at the first layer P1 and the second layer P2 are connected to the second frame 311 located inside the photovoltaic support assembly 100 in the auxiliary support member 30. Along the second direction X, the spacing between the second frames 311 located inside the photovoltaic support assembly 100 in the two auxiliary support members 30 is smaller than the spacing between the second frames 311 located outside the photovoltaic support assembly 100 in the two auxiliary support members 30. The second cables 50 are connected to the two second frames 311 with a smaller spacing, which can save materials for the second cables 50 and reduce the cost of the photovoltaic support assembly 100. In addition, when the second cables 50 are installed in the second frame 311 located inside the photovoltaic support assembly 100, they will not be blocked by another second frame 311 in the auxiliary support member 30, thereby facilitating the installation of the second cables 50.

[0085] It is understandable that in other embodiments, the second cable 50 may also be connected to the second frame 311 in the auxiliary support member 30 located outside the photovoltaic support assembly 100 .

[0086] In another embodiment, if Figure 5 As shown, the photovoltaic support assembly 100b and Figure 2 The structures of the photovoltaic support assembly 100 shown are substantially the same, except that the photovoltaic support assembly 100b further includes a plurality of fixing rods 90. The fixing rods 90 include opposite first ends 91 and second ends 93. Each fixing rod 90 is connected between two first cables 20 for installing the same photovoltaic assembly 201. The intersection of the second cable 50 located at the first layer P1 and the first cable 20 is fixedly connected to the first end 91 of the fixing rod 90. The intersection of the second cable 50 located at the second layer P2 and the first cable 20 is fixedly connected to the second end 93 of the fixing rod 90.

[0087] The fixing rod 90 is a hard structure and is not easy to deform. The fixing rod 90 is connected to the intersection of the first cable 20 and the second cable 50 of the first layer P1, and between the first cable 20 and the second cable 50 of the second layer P2, thereby improving the position stability between the two intersections. On the basis of the auxiliary support member 30 tightening and supporting the first cable 20 for the second cable 50, the fixing rod 90 further improves the tensioning effect between the second cable 50 and the first cable 20, thereby reducing the risk of the flexible first cable 20 and the second cable 50 deforming and displacing when subjected to external forces such as wind, thereby causing the photovoltaic assembly 201 to flip or twist.

[0088] It can be understood that in other embodiments, the auxiliary support member 30 may adopt other structures. For example, the auxiliary support member 30 may also be A-shaped.

[0089] For example, in another embodiment, Figure 6 As shown, the photovoltaic support assembly 100a and Figure 2 The structures of the photovoltaic support assembly 100 shown are substantially the same, except that the auxiliary support member 30a of the photovoltaic support assembly 100a is a column structure, and two adjacent second cables 50 are connected to the auxiliary support member 30a at intervals along the vertical direction Z.

[0090] For example, Figure 7 As shown, in another embodiment, the photovoltaic support assembly 100c and Figure 2 The structure of the photovoltaic support assembly 100 shown in FIG. 1 is substantially the same, except that the auxiliary support member 30c in the photovoltaic support assembly 100c is Figure 2The structure of the auxiliary support member 30 of the photovoltaic support assembly 100c shown is different. The auxiliary support member 30c includes a third cable 33 and a fourth cable 34. Every two third cables 33 are arranged in a group along the second direction X, and respectively hold the two ends of the second cable 50 located in the first layer P1. Every two fourth cables 34 are arranged in a group along the second direction X, and respectively hold the two ends of the second cable 50 located in the second layer P2. Through the holding of the second cable 50 by the third cable 33 and the fourth cable 34, the second cable 50 applies a holding force to the first cable 20, thereby improving the wind resistance of the portion of the first cable 20 between the brackets 10, so that the wind resistance of the photovoltaic support assembly 100c is improved.

[0091] To further improve the wind resistance of the photovoltaic support assembly 100, for example, in another embodiment, Figure 8 As shown, the photovoltaic support assembly 100e and Figure 7 The structure of the photovoltaic support assembly 100c shown is substantially the same, except that the photovoltaic support assembly 100e further includes a plurality of first support members 60 and a plurality of second support members 70. Fig. 9 As shown, the photovoltaic support assembly 100f and Figure 2 The structures of the photovoltaic support assembly 100 shown are substantially the same, except that the photovoltaic support assembly 100f further includes a plurality of first support members 60 and a plurality of second support members 70 .

[0092] Figure 8 The photovoltaic support assembly 100e shown and Fig. 9 In the photovoltaic support assembly 100f shown, each first support member 60 is supported and fixed at the intersection of the second cable 50 of the first layer P1 and the first cable 20 of the first layer P1, and each second support member 70 is supported and fixed at the intersection of the second cable 50 of the second layer P2 and the first cable 20 of the second layer P2. The second cable 50 and the first cable 20 are connected at the intersection, and the second cable 50 can tighten the first cable 20; the first support member 60 and the second support member 70 respectively support and fix the second cable 50 to provide support force for the first cable 20 along the vertical direction Z, so as to improve the wind resistance performance such as wind suction resistance and wind torsion resistance of the photovoltaic support assembly 100e and the photovoltaic support assembly 100f.

[0093] See also Figure 2 In one embodiment, the photovoltaic support assembly 100 further includes a plurality of auxiliary brackets 40. The plurality of auxiliary brackets 40 are located between two rows of first cables 20. Each auxiliary bracket 40 is configured to support two adjacent first cables 20 and is located between two adjacent auxiliary support members 30. Each first cable 20 is supported by at least one auxiliary bracket 40.

[0094] In one embodiment, the number of the auxiliary brackets 40 is eight. Every four auxiliary brackets 40 are arranged in a row along the second direction X. The eight auxiliary brackets 40 form two rows. The two rows of auxiliary brackets 40 are arranged along the first direction Y. Each row of auxiliary brackets 40 is located between two adjacent auxiliary support members 30.

[0095] It can be understood that in other embodiments, the number of auxiliary brackets 40 can also be four, five, ten, twelve, fourteen, sixteen, eighteen or other numbers.

[0096] It can be understood that in other embodiments, two rows, three rows, four rows or other numbers of auxiliary brackets 40 may be arranged between two adjacent auxiliary support members 30 .

[0097] The auxiliary bracket 40 provides support force for the first cable 20 between two adjacent auxiliary support members 30, further improving the wind resistance of the photovoltaic support assembly 100 against wind suction and wind torsion.

[0098] It can be understood that in other embodiments, the auxiliary bracket 40 can be omitted.

[0099] In one embodiment, in the photovoltaic support assembly 100, the second sub-bracket 41 includes two third frames 411 arranged along the second direction X. The two third frames 411 are respectively connected to the second crossbeam 43. The two third frames 411 respectively support two adjacent first cables 20 in a one-to-one correspondence. The two third frames 411 enhance the overall strength of the second sub-bracket 41, so as to enhance the supporting stability of the auxiliary bracket 40 on the first cable 20, thereby further enhancing the wind resistance of the photovoltaic support assembly 100.

[0100] In another embodiment, if Fig.10 As shown, the auxiliary support 40g includes a second sub-support 41g and a second crossbeam 43. The second crossbeam 43 is connected to two adjacent first cables 20. The second sub-support 41g is configured to support the second crossbeam 43. The second sub-support 41g is a column structure. The second sub-support 41g is connected to the symmetric center of the second crossbeam 43, but is not limited thereto. The second crossbeam 43 tightens the two adjacent first cables 20, and the second sub-support 41g supports the second crossbeam 43 and the two adjacent first cables 20 to improve the wind resistance of the photovoltaic support assembly 100g.

[0101] It is understood that the second sub-bracket may also adopt a column structure or two third frames 411, which may be set according to the installation inclination angle of the photovoltaic module 201 and the regional wind force. For example, when the wind force is small or the installation inclination angle is small, the second sub-bracket adopts a single column structure; when the wind force is large or the installation inclination angle is large, the second sub-bracket adopts two third frames 411.

[0102] Understandably, Figure 5The fixing rod 90 shown can also be applied to Figures 6 to 10 In the illustrated embodiment, the intersection of the second cable 50 and the first cable 20 located at the first layer P1 is fixedly connected to the first end 91 of the fixing rod 90; and the intersection of the second cable 50 and the first cable 20 located at the second layer P2 is fixedly connected to the second end 93 of the fixing rod 90.

[0103] In the photovoltaic support assembly 100 and the photovoltaic system 200, the two first sub-supports 11 of the support 10 are respectively connected to the two first cables 20, and the two first frames 111 of the first sub-support 11 are respectively inclined relative to the vertical direction Z, so that the first frame 111 is supported by the platform in a direction perpendicular to the vertical direction Z or inclined relative to the vertical direction Z, thereby being able to offset part of the external force in the horizontal direction. For example, when the support 10 resists the wind force in the second direction X, the first crossbeam 13 is supported between the two first sub-supports 11, and the four first frames 111 in the support 10 are 1 and at least one first cross beam 13 jointly resist wind force, so that the support 10 has a higher performance of resisting wind force relative to a single column extending along the vertical direction Z, including improved performance of resisting horizontal wind force; when the support 10 resists wind force in the first direction Y, the first frame body 111 is tilted to offset at least part of the horizontal wind force, thereby improving the performance of the support 10 resisting horizontal wind force, and the four first frames 111 and at least one first cross beam 13 of the support 10 resist wind force at the same time, so that the support 10 has a higher performance of resisting wind force relative to a single column extending along the vertical direction Z.

[0104] The above-mentioned photovoltaic support assembly 100 can change and adjust the span of the photovoltaic support assembly 100 to adapt to different terrains by adjusting the spacing between two adjacent brackets 10 along the second direction X and along the first direction Y, the spacing between two adjacent auxiliary support members 30, the spacing between two adjacent first support members 60, the spacing between two adjacent second support members 70, the spacing between two adjacent third cables 33, the spacing between two adjacent fourth cables 34, the spacing between two adjacent auxiliary brackets 40, and the number of brackets 10, auxiliary support members 30, first support members 60, second support members 70 and auxiliary brackets 40; by changing the height difference between two adjacent first cables 20 along the vertical direction Z, the inclination angle of the photovoltaic assembly 201 can be adjusted.

[0105] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not intended to be limiting of the present application. As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
