Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and more specifically, to a flexible photovoltaic support. Background Technology

[0002] The flexible photovoltaic support structure system is a spatial structure system composed of prestressed load-bearing cables and their supporting components. It has a simple structure, light weight, and can achieve large-span installation, avoiding unfavorable geographical factors such as undulating mountains and high vegetation.

[0003] The transverse structure flexible photovoltaic support is a type of flexible photovoltaic support that achieves large-span coverage through a horizontal tensioning system. The main load is borne by the transverse (horizontal) prestressed cable net. At the same time, in order to improve the stability of the photovoltaic support, it is usually fixed to the side columns by inclined cables at both ends of the transverse connection system. However, since the side columns do not directly participate in the photovoltaic array, the effective photovoltaic area is reduced, which leads to the power generation efficiency of the flexible photovoltaic system not meeting the maximum demand.

Detailed Implementation

[0055] The core of this application is to provide a flexible photovoltaic support structure that improves the stability and wind resistance of the flexible photovoltaic support structure while increasing the effective photovoltaic area, thereby maximizing the power generation efficiency of the flexible photovoltaic system.

[0056] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0057] The transverse structure flexible photovoltaic support is a type of flexible photovoltaic support that achieves large-span coverage through a horizontal tensioning system. The main load is borne by the transverse (horizontal) prestressed cable net. At the same time, in order to improve the stability of the photovoltaic support, it is usually fixed to the side columns by inclined cables at both ends of the transverse connection system. However, since the side columns do not directly participate in the photovoltaic array, the effective photovoltaic area is reduced, which leads to the power generation efficiency of the flexible photovoltaic system not meeting the maximum demand.

[0058] Therefore, such as Figure 1As shown in the figure, this application discloses a flexible photovoltaic support 100, including a first cable truss assembly 10, a second cable truss assembly 20, and a connecting assembly 30. The wind-resistant frame 131 is connected to a stabilizing cable 132 and a first main cable assembly 11 on both sides, forming a single unit with the stabilizing cable 132. This allows the vertical load of the photovoltaic module to be transferred to the stabilizing cable 132 via the wind-resistant frame 131, addressing the issues of excessive planar deflection and poor wind resistance in the flexible photovoltaic support 100. Simultaneously, the transverse tension cable 31 of the connecting assembly 30 forms a continuous transverse connection system with the first cable truss assembly 10, reducing the swaying of the first cable truss assembly 10. Furthermore, the transverse tension cable 31 can be fixed to the second support assembly 22 of the second cable truss assembly 20, and the second main cable assembly 21, anchored to the second support assembly 22, can hold the photovoltaic module. This improves the stability and wind resistance of the flexible photovoltaic support 100 while increasing the effective photovoltaic area, maximizing the power generation efficiency of the flexible photovoltaic system.

[0059] The following will combine Figures 1 to 7 The flexible photovoltaic support 100 disclosed in the embodiments of this application will be explained and described in detail.

[0060] like Figure 1As shown, the first cable truss assembly 10 can be arranged in multiple rows along a first direction, that is, the first cable truss assembly 10 can have two, three, four or more rows, and each first cable truss assembly 10 is distributed along the first direction. The first cable truss assembly 10 may include a first main cable assembly 11, a first support assembly 12, and a wind-resistant assembly 13. The first main cable assembly 11 may include two parallel first main cables 111, on which photovoltaic modules can be placed. The first support assembly 12 may include at least two, and the two ends of the first main cable assembly 11 can be anchored to the first support assembly 12 respectively to bear the tension from the first main cable assembly 11 and transmit it to the ground foundation. Meanwhile, the wind-resistant assembly 13 may include a wind-resistant frame 131 and a stabilizing cable 132, with the wind-resistant frame 131 located between two adjacent first support assemblies 12. The wind-resistant frame 131 has two opposite sides; for ease of understanding, the two sides of the wind-resistant frame 131 are defined as the first side and the second side, respectively. The first main cable assembly 11 can be connected to the first side of the wind-resistant frame 131. One stabilizing cable 132 can be used, with both ends of the stabilizing cable 132 connected to the first support assembly 12. Simultaneously, the stabilizing cable 132 is connected to the second side of the wind-resistant frame 131, thus forming a three-cable spatial structure system between the first main cable assembly 11 and the stabilizing cable 132. This transfers the vertical load of the photovoltaic module to the stabilizing cable 132 through the wind-resistant frame 131, improving the wind resistance of the flexible photovoltaic support 100. Alternatively, two or more stabilizing cables 132 can be used, forming a four-cable spatial structure system with the first main cable assembly 11, thereby improving the overall stability and wind resistance of the first cable truss assembly 10. It should be noted that the first direction is the extension direction perpendicular to the first main cable assembly 11.

[0061] like Figure 1 As shown, the second cable truss assembly 20 may be adjacent to the outermost first cable truss assembly 10 along the first direction, and the second cable truss assembly 20 may include a second main cable assembly 21 and a second support assembly 22. The second main cable assembly 21 may include two parallel second main cables 211, and photovoltaic modules may be placed on the two second main cables 211 of the second main cable assembly 21. Multiple second support assemblies 22 may be used, i.e., two, three, four, or more second support assemblies 22 may be used. The distance between two adjacent second support assemblies 22 is less than the distance between two adjacent first support assemblies 12, thereby improving the wind resistance of the second cable truss assembly 20 by reducing the distance of each span. The two ends of the second main cable assembly 21 may be anchored to the second support assembly 22 respectively to bear the tension from the second main cable assembly 21 and transmit it to the ground foundation.

[0062] like Figure 1As shown, at least one connecting component 30 is provided along the second direction of the first cable truss assembly 10, meaning that there can be one, two, three, or more connecting components 30. Each connecting component 30 may include at least two transverse cables 31, meaning that there can be two, three, or more transverse cables 31 spaced apart. Each transverse cable 31 can pass through the wind-resistant frame 131 of each row of the first cable truss assembly 10 and be connected to the second support component 22 via a transverse fixing component 40. This allows the transverse cables 31 of the connecting component 30 and the first cable truss assembly 10 to form a continuous transverse connection system, creating a flexible photovoltaic support 100 structure that reduces the swaying of the first cable truss assembly 10. Furthermore, the transverse cables 31 can be fixed to the second support component 22 of the second cable truss assembly 20, and the second main cable component 21 anchored to the second support component 22 can hold photovoltaic modules. This improves the stability and wind resistance of the flexible photovoltaic support 100 while increasing the effective photovoltaic area, thereby maximizing the power generation efficiency of the flexible photovoltaic system. It should be noted that the second direction is perpendicular to the first direction, that is, the second direction is the extension direction parallel to the first main cable assembly 11.

[0063] In some embodiments, the transverse cable 31 can be made of flexible cable such as steel strand, which has high strength and good flexibility. This allows the transverse cable 31 to absorb dynamic energy through elastic deformation when the photovoltaic support is subjected to alternating loads such as wind vibration and snow load, thereby reducing the peak stress of the structure and ensuring the stability of the flexible photovoltaic support 100.

[0064] The flexible photovoltaic support 100 disclosed in this application embodiment is anchored to two first support components 12 via a first main cable assembly 11 to transfer the tension from the first main cable assembly 11 to the ground foundation. Simultaneously, a wind-resistant frame 131 is located between two adjacent first support components 12, and both sides of the wind-resistant frame 131 are connected to the first main cable assembly 11 and a stabilizing cable 132, respectively. Furthermore, at least two transverse tension cables 31 of the connecting component 30 pass through the wind-resistant frame 131 of each row of first cable truss assemblies 10 and are connected to second support components 22 via transverse fixing components 40. Photovoltaic modules can be placed on the second main cable assembly 21, which is anchored to two second support components 22 to transfer the tension from the second main cable assembly 21 to the ground foundation.

[0065] The flexible photovoltaic support 100 disclosed in this application is connected to the stabilizing cable 132 and the first main cable assembly 11 on both sides of the wind-resistant frame 131, so that the first main cable assembly 11 and the stabilizing cable 132 form a whole. This allows the vertical load of the photovoltaic module to be transferred to the stabilizing cable 132 through the wind-resistant frame 131, thereby solving the problems of excessive planar deflection and poor wind resistance of the flexible photovoltaic support 100. At the same time, the flexible photovoltaic support 100 structure, which is connected to the first cable truss assembly 10 by the transverse cable 31 of the connecting assembly 30, forms a continuous transverse connection system, which can reduce the swaying of the first cable truss assembly 10. In addition, the transverse cable 31 can be fixed to the second support assembly 22 of the second cable truss assembly 20, and the second main cable assembly 21, which is anchored to the second support assembly 22, can place the photovoltaic module. This improves the stability and wind resistance of the flexible photovoltaic support 100, while increasing the effective photovoltaic area, thereby maximizing the power generation efficiency of the flexible photovoltaic system.

[0066] In some embodiments, such as Figures 1 to 3 As shown, to ensure that the photovoltaic modules have a large light-receiving area, the vertical height of one of the two first main cables 111 can be greater than the vertical height of the other. This allows the photovoltaic modules mounted on the two first main cables 111 to be arranged at an angle, ensuring that the photovoltaic modules have a larger area to receive sunlight, thereby improving the power generation efficiency of the photovoltaic modules. Similarly, the vertical height of one of the two second main cables 211 can also be greater than the vertical height of the other, allowing the photovoltaic modules mounted on the two second main cables 211 to be arranged at an angle, thereby ensuring that the photovoltaic modules have a larger area to receive sunlight, thereby improving the power generation efficiency of the photovoltaic modules.

[0067] In some embodiments, the wind-resistant component 13 may further include one or more wind-resistant cables. The two ends of the wind-resistant cable may be connected to the first support component 12, and the wind-resistant cable is also connected to the second side of the wind-resistant frame 131. This allows the wind-resistant cable to apply a downward pulling force to the wind-resistant frame 131, thereby limiting the vertical displacement of the wind-resistant frame 131 when subjected to wind suction and lifting. This improves the wind resistance and stability of the flexible photovoltaic support 100 and reduces the risk of microcracks in the photovoltaic modules.

[0068] In some embodiments, such as Figure 1As shown, multiple wind-resistant frames 131 located between the two first support components 12 can be arranged along the second direction, that is, there can be two, three or more wind-resistant frames 131. At the same time, wind-resistant cables are connected to each wind-resistant frame 131 respectively, and the middle part of the wind-resistant cable is arched upward, that is, the vertical height of the middle part of the wind-resistant cable is greater than the vertical height of other parts of the wind-resistant cable. In this way, while limiting the vertical displacement of the wind-resistant frame 131 caused by wind suction and wind lifting, the space utilization rate under the photovoltaic module of the flexible photovoltaic support can be improved, and the span of the flexible photovoltaic support can be increased, thereby realizing the advantages of large span and large headroom of the flexible photovoltaic support.

[0069] In some embodiments, such as Figure 2 and Figure 3 As shown, the wind-resistant frame 131 may include a first diagonal brace 1311, a second diagonal brace 1312, and a vertical rod 1313. The first diagonal brace 1311 and the second diagonal brace 1312 intersect at one end of the vertical rod 1313 at a predetermined angle, meaning both the first diagonal brace 1311 and the second diagonal brace 1312 are connected to one end of the vertical rod 1313. The predetermined angle between the first diagonal brace 1311 and the second diagonal brace 1312 gives the wind-resistant frame 131 a "Y"-shaped structure. The predetermined angle can be 30°, 45°, 60°, 90°, etc. Meanwhile, a base plate 1317 can be provided at the bottom of the vertical rod 1313, and a first connecting hole is provided on the base plate 1317 so that the stabilizing cable 132 and the wind-resistant cable can be connected to the base plate 1317 of the vertical rod 1313 through U-shaped fasteners, or directly pass through the through hole of the vertical rod 1313 and be locked and fixed by anchors. The free ends of the first diagonal rod 1311 and the second diagonal rod 1312 can be provided with connecting seats, and the connecting seats can be provided with second connecting holes for fixing U-shaped fasteners, so that the two first main cables 111 can be fixed to the connecting seats of the free ends of the first diagonal rod 1311 and the second diagonal rod 1312 through U-shaped fasteners, so as to realize the connection and fixation between the two first main cables 111 and the free ends of the first diagonal rod 1311 and the second diagonal rod 1312 respectively. The transverse cables 31 can be passed through both ends of the vertical rod 1313 and connected and fixed to the second support assembly 22 through the transverse fixing assembly 40.

[0070] In some embodiments, such as Figure 2 and Figure 3 As shown, to improve the stability and strength of the wind-resistant frame 131, a first wind-resistant reinforcing rod 1314 can be provided between the first diagonal rod 1311 and the second diagonal rod 1312. One or more first wind-resistant reinforcing rods 1314 can be used, and the first wind-resistant reinforcing rod 1314 can be welded between the first diagonal rod 1311 and the second diagonal rod 1312. Of course, as... Figure 6 and Figure 7As shown, the first wind-resistant reinforcing rod 1314 may also have bent portions at both ends that are parallel to the first inclined rod 1311 and the second inclined rod 1312, so that the bent portions at both ends of the first wind-resistant reinforcing rod 1314 can be welded to the first inclined rod 1311 and the second inclined rod 1312 respectively, thereby increasing the connection area and ensuring the connection strength. Alternatively, the bent portions at both ends of the first wind-resistant reinforcing rod 1314 can be connected to the first inclined rod 1311 and the second inclined rod 1312 respectively by bolts or other fasteners.

[0071] In some embodiments, such as Figure 2 and Figure 3 As shown, the vertical height of the free end of the first inclined rod 1311 can be greater than the vertical height of the free end of the second inclined rod 1312, that is, the length of the first inclined rod 1311 is greater than the length of the second inclined rod 1312, so that the vertical height of the first main cable 111 connected to the free end of the first inclined rod 1311 is greater than the vertical height of the first main cable 111 connected to the free end of the second inclined rod 1312. This allows the photovoltaic modules installed on the two first main cables 111 to be arranged at an angle, so as to ensure that the photovoltaic modules have a larger area to receive sunlight, thereby improving the power generation efficiency of the photovoltaic modules. Of course, the vertical height of the free end of the first inclined rod 1311 can also be made equal to the vertical height of the free end of the second inclined rod 1312, that is, the free ends of the first inclined rod 1311 and the free ends of the second inclined rod 1312 are on the same plane. At the same time, the height of the connecting seat of the free end of the first inclined rod 1311 is greater than the height of the connecting seat of the free end of the second inclined rod 1312, so that the vertical height of the first main cable 111 connected to the free end of the first inclined rod 1311 is greater than the vertical height of the first main cable 111 connected to the free end of the second inclined rod 1312, so as to ensure a larger light-receiving area of ​​the photovoltaic module.

[0072] In some embodiments, such as Figure 2 and Figure 3 As shown, the wind-resistant frame 131 can adopt an integral structure, that is, the first diagonal bar 1311, the second diagonal bar 1312, and the vertical bar 1313 can be integrally die-cast to form the wind-resistant frame 131. Of course, the wind-resistant frame 131 can also adopt a split structure, that is, the first diagonal bar 1311, the second diagonal bar 1312, and the vertical bar 1313 can be connected by welding or bolting to form the wind-resistant frame 131.

[0073] In some embodiments, such as Figure 6 and Figure 7As shown, the wind-resistant frame 131 can be formed by splicing a first sub-frame and a second sub-frame. The first sub-frame can consist of a first diagonal brace 1311 and a first vertical brace, and the first vertical brace and the first diagonal brace 1311 can be integrally formed. The second sub-frame can consist of a second diagonal brace 1312 and a second vertical brace, and the second vertical brace and the second diagonal brace 1312 can be integrally formed. The first and second vertical braces together form a vertical rod 1313. The first and second sub-frames can be connected by welding or fasteners such as bolts through an intermediate splicing plate 1315 and a bottom splicing plate 1316.

[0074] In some embodiments, such as Figure 7 As shown, one intermediate splicing plate 1315 and one bottom splicing plate 1316 can each be used. The intermediate splicing plate 1315 can be connected to the middle position of the first sub-frame and the second sub-frame simultaneously by bolts or other fasteners, and is located on one side of the first sub-frame and the second sub-frame. The bottom splicing plate 1316 can be connected to the bottom position of the first sub-frame and the second sub-frame simultaneously by bolts or other fasteners, and is located on one side of the first sub-frame and the second sub-frame.

[0075] In some embodiments, two intermediate splicing plates 1315 and two bottom splicing plates 1316 may each be used, and the two intermediate splicing plates 1315 may be located on one side of the middle position of the first sub-frame and the second sub-frame, respectively, so that the connection and fixation between the intermediate splicing plates 1315, the first sub-frame and the second sub-frame can be achieved by fasteners such as bolts passing through the two intermediate splicing plates 1315, the first sub-frame and the second sub-frame. Similarly, as Figure 6 As shown, the bottom splicing plate 1316 can be located on one side of the bottom position of the first sub-frame and the second sub-frame respectively, so that the connection and fixation between the bottom splicing plate 1316, the first sub-frame and the second sub-frame can be achieved by fasteners such as bolts passing through the two bottom splicing plates 1316, the first sub-frame and the second sub-frame.

[0076] It should be noted that, as Figure 6 As shown, the first and second sub-frames can also be connected by a middle splicing plate 1315 and two bottom splicing plates 1316, or the first and second sub-frames can also be connected by two middle splicing plates 1315 and one bottom splicing plate 1316. For specific implementation methods, please refer to the above embodiments, which will not be repeated here.

[0077] In some embodiments, such as Figure 2 As shown, the first support assembly 12 may include a first end bracket 121. The first end bracket 121 may include at least one first end post 1211 and a first end crossbeam 1212 disposed on the first end post 1211, i.e., as shown... Figure 2As shown, one first end post 1211 can be used, and the first end beam 1212 can be located on top of the first end post 1211. Of course, two first end posts 1211 can also be used, and the two ends of the first end beam 1212 can be located on top of the two first end posts 1211 respectively, so that the first main cable assembly 11 and the stabilizing cable 132 can be connected to the first end beam 1212 respectively through anchors. At the same time, the wind-resistant cable can be connected to the first end post 1211 through clamps.

[0078] In some embodiments, in order to achieve a height difference between the two first main cables 111, such as Figure 2 As shown, the first end beam 1212 can be inclinedly set on top of the first end column 1211, that is, the vertical height of one end of the first end beam 1212 is greater than the vertical height of the other end of the first end beam 1212, thereby creating a height difference between the two first main cables 111 connected to both ends of the first end beam 1212, ensuring that the photovoltaic module has a large light-receiving surface. Of course, the first end beam 1212 can also be set horizontally, and at least one first bracket can be set on the first end beam 1212. Specifically, one first bracket can be set on the first end beam 1212, and one of the two first main cables 111 is connected to the first bracket, while the other is directly connected to the first end beam 1212, creating a height difference between the two first main cables 111. Alternatively, two first brackets can be set on the first end beam 1212, with the height of one first bracket greater than the height of the other, thereby creating a height difference between the first main cables 111 connected to the two first brackets respectively, ensuring that the photovoltaic module has a large light-receiving surface. It should be noted that, as Figure 1 and Figure 2 As shown, in the first direction of the first cable truss assembly 10, the first end crossbeams 1212 of each first cable truss assembly 10 can be set independently. Of course, in the first direction of the first cable truss assembly 10, the first end crossbeams 1212 of each first cable truss assembly 10 can also be continuously distributed to improve the overall stability of the first end support 121 of the flexible photovoltaic support 100.

[0079] In some embodiments, when the span of the flexible photovoltaic support 100 is large, such as Figure 1 and Figure 3 As shown, the first support assembly 12 may further include a first central bracket 122. Wherein, as... Figure 3As shown, the first central support 122 may include at least one first central column 1221 and a first central beam 1222 disposed on the first central column 1221. That is, one first central column 1221 may be used, and the first central beam 1222 may be located at the top of the first central column 1221. Of course, two first central columns 1221 may also be used, and the two ends of the first central beam 1222 may be located at the top of the two first central columns 1221 respectively, so that the first main cable assembly 11 and the stabilizing cable 132 can be connected to the first central beam 1222 respectively through anchors. At the same time, the wind-resistant cable can be connected to the first central column 1221 through clamps.

[0080] In some embodiments, such as Figure 3 As shown, in order to achieve a height difference between the two first main cables 111, the first middle crossbeam 1222 can be inclinedly set on the top of the first middle column 1221, that is, the vertical height of one end of the first middle crossbeam 1222 is greater than the vertical height of the other end of the first middle crossbeam 1222, thereby achieving a height difference between the two first main cables 111 connected to the two ends of the first middle crossbeam 1222, ensuring that the photovoltaic module has a large light-receiving surface. Of course, the first central crossbeam 1222 can also be horizontally arranged, and at least one second support can be provided on the first central crossbeam 1222. Specifically, one second support can be provided on the first central crossbeam 1222, with one of the two first main cables 111 connected to the second support and the other directly connected to the first central crossbeam 1222, creating a height difference between the two first main cables 111. Alternatively, two second supports can be spaced apart on the first central crossbeam 1222, with one second support having a greater height than the other, thus creating a height difference between the first main cables 111 connected to the two second supports respectively, ensuring that the photovoltaic module has a large light-receiving surface. It should be noted that in the first direction of the first cable truss assembly 10, such as... Figure 1 and Figure 3 As shown, the first central crossbeam 1222 of each first cable truss assembly 10 can be set independently. Of course, in the first direction of the first cable truss assembly 10, the first central crossbeam 1222 of each first cable truss assembly 10 can also be continuously distributed to improve the overall stability of the first central support 122 of the flexible photovoltaic support 100.

[0081] In some embodiments, such as Figure 1As shown, the second cable truss assembly 20 can be arranged in at least two rows along the first direction, that is, the second cable truss assembly 20 can have two, three or more rows, and each row of the second cable truss assembly 20 is distributed side by side along the first direction. Meanwhile, the second support assembly 22 can include two second end supports 221 and multiple second middle supports 222 located between two adjacent second end supports 221. The transverse cable 31 can be connected to the second middle supports 222 adjacent to the first cable truss assembly 10 via a transverse fixing assembly 40. The transverse fixing assembly 40 can be connected to the second middle supports 222 of the adjacent row of second cable truss assemblies 20 via diagonal tie members 223, so that the transverse fixing assembly 40 is under tension on both sides, improving the stability of the transverse fixing assembly 40, and thus ensuring the overall stability of the flexible photovoltaic support 100. It should be noted that the diagonal tie member 223 can be a flexible tension member such as steel strand or steel wire rope.

[0082] In some embodiments, such as Figure 2 As shown, the second end support 221 may include at least one second end column 2211 and a second end beam 2212 disposed on the second end column 2211. That is, one second end column 2211 may be used, and the second end beam 2212 may be located on the top of the second end column 2211. Of course, two second end columns 2211 may also be used, and the two ends of the second end beam 2212 may be located on the top of the two second end columns 2211 respectively, so that the second main cable assembly 21 can be connected to the second end beam 2212 by anchors.

[0083] In some embodiments, such as Figure 2 As shown, in order to achieve a height difference between the two second main cables 211, the second end beam 2212 can be inclinedly set on the top of the second end column 2211. That is, the vertical height of one end of the second end beam 2212 can be greater than the vertical height of the other end of the second end beam 2212, thereby achieving a height difference between the two second main cables 211 connected to the two ends of the second end beam 2212, ensuring that the photovoltaic module has a large light-receiving surface. Of course, the second end crossbeam 2212 can also be horizontally arranged, and at least one third support can be provided on the second end crossbeam 2212. Specifically, one second support can be provided on the second end crossbeam 2212, and one of the two second main cables 211 is connected to the third support, while the other is directly connected to the second end crossbeam 2212, creating a height difference between the two second main cables 211. Alternatively, two third supports can be spaced apart on the second end crossbeam 2212, with one third support having a greater height than the other, thus creating a height difference between the second main cables 211 connected to the two third supports respectively, ensuring that the photovoltaic module has a large light-receiving surface. It should be noted that in the first direction of the second cable truss assembly 20, such as... Figure 1 and Figure 2 As shown, the second end crossbeams 2212 of each second cable truss assembly 20 can be set independently. Of course, in the first direction of the second cable truss assembly 20, the second end crossbeams 2212 of each second cable truss assembly 20 can also be continuously distributed to improve the overall stability of the second end support 221 of the flexible photovoltaic support 100.

[0084] In some embodiments, such as Figure 3 As shown, the second central support 222 may include at least one second central column 2221 and a second central crossbeam 2222 disposed on the second central column 2221. That is, one second central column 2221 may be used, and the second central crossbeam 2222 may be located at the top of the second central column 2221. Of course, two second central columns 2221 may also be used, and the two ends of the second central crossbeam 2222 may be located at the top of the two second central columns 2221 respectively, so that the second main cable assembly 21 can be connected to the second central crossbeam 2222 through anchorage, and the diagonal tie 223 can be connected to the second central column 2221 through clamp.

[0085] In some embodiments, such as Figure 3 As shown, in order to achieve a height difference between the two second main cables 211, the second middle crossbeam 2222 can be inclinedly set on the second middle column 2221. That is, the vertical height of one end of the second middle crossbeam 2222 can be greater than the vertical height of the other end of the second middle crossbeam 2222, thereby achieving a height difference between the two second main cables 211 connected to the two ends of the second middle crossbeam 2222, ensuring that the photovoltaic module has a large light-receiving surface. Of course, the second central crossbeam 2222 can also be horizontally arranged, and at least one fourth support can be provided on the second central crossbeam 2222. Specifically, one fourth support can be provided on the second central crossbeam 2222, with one of the two second main cables 211 connected to the fourth support and the other directly connected to the second central crossbeam 2222, creating a height difference between the two second main cables 211. Alternatively, two fourth supports can be spaced apart on the second central crossbeam 2222, with one fourth support having a greater height than the other, thus creating a height difference between the second main cables 211 connected to the two fourth supports respectively, ensuring that the photovoltaic module has a larger light-receiving surface. It should be noted that in the first direction of the second cable truss assembly 20, such as... Figure 1 and Figure 3 As shown, the second central crossbeam 2222 of each second cable truss assembly 20 can be set independently. Of course, in the first direction of the second cable truss assembly 20, the second central crossbeam 2222 of each second cable truss assembly 20 can also be continuously distributed to improve the overall stability of the second central support 222 of the flexible photovoltaic support 100.

[0086] In the above embodiments, both the first end support 121 and the second end support 221 can be connected and fixed to the pile foundation using multiple stay cables. That is, both the first end support 121 and the second end support 221 can be connected and fixed to the pile foundation using two, three, four or more stay cables respectively, to adapt to scenarios with large inclined tension, such as mountainous areas. When two or more stay cables are used, each stay cable can be symmetrically distributed on both sides of the first end beam 1212 or the second end beam 2212, and one end of each stay cable can be connected to the first end beam 1212 or the second end beam 2212, while the other end of each stay cable can be connected to the pile foundation respectively, thereby improving the stability of the first end support 121 and the second end support 221.

[0087] In some embodiments, such as Figure 4 As shown, the lateral fixing assembly 40 may include a first fixing frame 41 and a first traction member 42. The first fixing frame 41 can be fixed to the second central column 2221 of the second support assembly 22, and the second central crossbeam 2222 can be fixed to the first fixing frame 41. Both ends of the first traction member 42 can be connected to two lateral cables 31 respectively, and the first traction member 42 can also be connected to the first fixing frame 41, so that the two lateral cables 31 are fixed through the lateral fixing assembly 40 to the second support assembly 22. It should be noted that the first traction member 42 can be a flexible component such as a steel wire rope.

[0088] In some embodiments, such as Figure 4 As shown, the first fixing frame 41 may include a first support column and a first connecting frame connected to one side of the first support column. The first support column may be fixed to a second central column 2221, and a second central crossbeam 2222 may be fixed to the first support column. A first traction member 42 may be connected to the first connecting frame. The first connecting frame may adopt a trapezoidal frame structure, with its bottom edge connected to one side of the first support column. The first connecting frame may also be equipped with a first reinforcing member, which may be one or more and connected to the inner side of the first connecting frame, thereby improving the overall strength and stability of the first fixing frame 41.

[0089] In some embodiments, such as Figure 4As shown, the transverse fixing assembly 40 may further include a pulley block 43 and a loading member 44. The pulley block 43 may include at least two fixed pulleys 431, i.e., two, three, or more fixed pulleys 431 may be used, and each fixed pulley 431 may be mounted on the first connecting frame of the first fixing frame 41. Simultaneously, the first traction member 42 may be wound around each fixed pulley 431, and the loading member 44 is directly or indirectly connected to the first traction member 42, so that the loading member 44 can apply a preset tension force to the transverse cable 31 through the first traction member 42, ensuring the wind resistance and stability of the flexible photovoltaic support 100. It should be noted that the loading member 44 may be a concrete block or similar material with a certain weight.

[0090] In some embodiments, such as Figure 4 As shown, two fixed pulleys 431 can be used. For ease of understanding, the two fixed pulleys 431 are defined as the first fixed pulley and the second fixed pulley, respectively. The first fixed pulley can be located on the side of the first connecting frame closer to the wind-resistant frame 131, and the second fixed pulley can be located on the side of the first connecting frame away from the wind-resistant frame 131 and arranged vertically at intervals from the first fixed pulley, so that the first traction member 42 wrapped around the two fixed pulleys 431 is on the same axis as the two transverse cables 31, thereby ensuring the stability of the preset tension force transmission.

[0091] In some embodiments, such as Figure 4 As shown, the pulley block 43 may also include a movable pulley 432, and the first traction member 42 may be placed around the movable pulley 432. At the same time, the loading member 44 may be connected to the movable pulley 432 to realize the dynamic adjustment of the position of the loading member 44.

[0092] In some embodiments, such as Figure 4 As shown, the lateral fixing assembly 40 may further include anti-derailment cables 45, and two anti-derailment cables 45 may be used to connect to two lateral tension cables 31 respectively, thereby preventing the risk of the lateral tension cables 31 falling off due to the breakage of the first traction member 42. For ease of understanding, the two anti-derailment cables 45 are defined as the first anti-derailment cable and the second anti-derailment cable, respectively. One end of the first anti-derailment cable can be connected to the upper lateral tension cable 31 through an anchor, and one end of the first traction member 42 is connected to the anchor, so that the upper lateral tension cable 31 can be connected to both the first traction member 42 and the first anti-derailment cable simultaneously. The other end of the first anti-derailment cable can be connected to the first support column. One end of the second anti-derailment cable can be connected to the lower lateral tension cable 31 through an anchor, and the other end of the first traction member 42 is connected to the anchor, so that the lower lateral tension cable 31 can be connected to both the first traction member 42 and the first anti-derailment cable simultaneously. The other end of the second anti-derailment cable can be connected to the first connecting frame. Meanwhile, in order to prevent the loading member 44 from falling off, one end of the loading member 44 can be connected to the movable pulley 432, and the other end of the loading member 44 can be connected to the second central column 2221 through a flexible cable.

[0093] In some embodiments, such as Figure 5 As shown, the lateral fixing assembly 40 may include a second fixing frame 46, a rotating member 47, and a traction assembly 48. The second fixing frame 46 can be fixed to the second central column 2221 of the second support assembly 22, and the second central crossbeam 2222 can be fixed to the second fixing frame 46. Meanwhile, the rotating member 47 is rotatably mounted on the second fixing frame 46, and both lateral cables 31 can be connected to the rotating member 47. The rotating member 47 can be connected to the second fixing frame 46 via the traction assembly 48, so that when the rotating member 47 rotates, the traction assembly 48 can absorb the energy of the rotating member 47, thereby suppressing the impact of the lateral cables 31 on the rotating member 47.

[0094] In some embodiments, such as Figure 5 As shown, the second fixing frame 46 may include a second support column and two second connecting frames connected to one side of the second support column. The second support column can be fixed to the second central column 2221, and the second central crossbeam 2222 can be fixed to the second support column. The second connecting frames may adopt a triangular structure, and the rotating member 47 can be connected between the two second connecting frames via a pin to achieve a rotatable connection between the rotating member 47 and the second connecting frames. The rotating member 47 can be connected to the second support column via a traction assembly 48 to absorb the energy of the rotating member 47, thereby suppressing the impact of the transverse cable 31 on the rotating member 47. Of course, the second connecting frame may be provided with a second reinforcing member, and one or more second reinforcing members may be used and connected to the inner side of the second connecting frame, thereby improving the overall strength and stability of the second fixing frame 46.

[0095] In some embodiments, such as Figure 5 As shown, the traction assembly 48 may include a second traction member 481 and a damper 482. Two second traction members 481 may be used, and the two second traction members 481 may be connected to the two ends of the rotating member 47 respectively. At the same time, the two ends of each second traction member 481 may be connected to the rotating member 47 and the second fixed frame 46 respectively. The damper 482 may be disposed on the second traction member 481 to absorb the energy of the rotating member 47 through the damper 482, thereby suppressing the impact of the transverse cable 31 on the rotating member 47.

[0096] In some embodiments, such as Figure 5As shown, the rotating component 47 may include a rotating rod 471 and a reinforcing frame 472 connected to the rotating rod 471. The rotating rod 471 is connected to one end of the two second connecting frames and close to the wind-resistant frame 131 by a pin, so that the rotating rod 471 can drive the reinforcing frame 472 to rotate synchronously. At the same time, both ends of the rotating rod 471 are connected to traction components 48 and transverse cables 31, that is, the two transverse cables 31 are respectively connected to the two ends of the rotating rod 471, and the two traction components 48 are respectively connected to the two ends of the rotating rod 471, so that the energy of the rotating component 47 is absorbed by the damper 482, thereby suppressing the impact of the transverse cables 31 on the rotating component 47.

[0097] In the above embodiments, the damper 482 can be a hydraulic damper, a viscous damper, an electromagnetic damper, etc., to absorb the energy of the rotating component 47, thereby suppressing the impact of the transverse cable 31 on the rotating component 47.
