Description

Technical Field

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

[0002] Flexible tracking photovoltaic (PV) brackets are widely used in large flat areas, gentle slopes, and sandy wastelands. They not only demonstrate the cost advantages of tracking brackets but also do not compromise the original advantages of cable-stayed PV structures, such as high clearance and large spans. However, to improve the tracking performance of flexible tracking PV brackets, drive components need to be installed at both ends of each span.

[0003] Therefore, how to design a multi-row flexible tracking photovoltaic system that can reduce costs while maintaining the tracking performance of flexible tracking photovoltaic systems has become a technical problem that urgently needs to be solved by those skilled in the art.

[0029] In some embodiments, the wind-resistant assembly further includes two wind-resistant cables, the two ends of which are respectively connected to the crossbeam assembly, and the two wind-resistant cables are arranged crosswise and connected to the second side of the wind-resistant frame.

[0030] In some embodiments, the wind-resistant component further includes an anti-arch cable and a vertical cable, with both ends of the anti-arch cable connected to the support component, one end of the vertical cable connected to the first side of the wind-resistant frame, and the other end of the vertical cable connected to the anti-arch cable, so that the middle of the anti-arch cable arches upward.

[0031] In some embodiments, the wind-resistant frame includes an upper chord, a lower chord, and a connecting chord. The upper and lower chords are arranged in parallel, and the two ends of the connecting chord are respectively connected to one end of the upper chord and one end of the lower chord. The upper chord, lower chord, and connecting chord form at least one planar wind-resistant structure.

[0032] The upper chord and / or lower chord are equipped with locking devices at both ends for locking the main cable, stabilizing cable or wind-resistant cable.

[0035] In some embodiments, the U-shaped clip is detachably or non-detachably connected to the upper or lower chord.

[0036] And / or, the locking position and connecting chord may be detachably or non-detachably connected.

[0037] In some embodiments, the U-shaped clip and the two connecting lugs are provided with mounting holes for fasteners.

[0038] In some embodiments, one of the two connecting lugs is provided with a locking element for locking the main cable, stabilizing cable, or wind-resistant cable; the other of the two connecting lugs is provided with a clearance notch to avoid the locking element.

[0045] As can be seen from the above examples, in the multi-row flexible tracking photovoltaic support of this application, the crossbeam assembly at the active end can drive all the crossbeam assemblies at the first driven end to rotate in linkage through the first transmission beam and the second transmission beam, respectively, and all the crossbeam assemblies at the second driven end to rotate in linkage. That is, at least three adjacent support assemblies in the second direction can be driven by a driving assembly to achieve linkage rotation. Therefore, while improving the tracking effect of the flexible tracking photovoltaic support, the application of driving assemblies can be reduced, and the cost can also be reduced.

[0046] Furthermore, at the first driven end, from the m-th stage first driven end to the 1st stage first driven end, the cross-sectional area of ​​the first transmission sub-beam gradually increases, offsetting the torque accumulation from the m-th stage first driven end to the 1st stage first driven end, thereby improving the transmission stability of the first transmission beam. Similarly, at the second driven end, from the n-th stage second driven end to the 1st stage second driven end, the cross-sectional area of ​​the second transmission sub-beam gradually increases, offsetting the torque accumulation from the n-th stage second driven end to the 1st stage second driven end, thereby improving the transmission stability of the second transmission beam.

[0080] The core of this application is to provide a multi-row flexible tracking photovoltaic bracket, which improves the tracking effect of the flexible tracking photovoltaic bracket while reducing the application of drive components.

[0081] 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.

[0082] See Figures 1 to 2 The multi-row flexible tracking photovoltaic bracket includes at least three rows of flexible tracking photovoltaic brackets 100, which extend along a first direction and are arranged side by side in a second direction, which is perpendicular to the first direction; each of the at least three rows of flexible tracking photovoltaic brackets 100 includes a support component 1 and a crossbeam component 2, which is rotatably mounted on the support component 1.

[0083] In at least three adjacent support components 1 in the second direction: one support component 1 located in the middle is located at the active end, and the support component 1 is provided with a drive component 3 to drive the corresponding crossbeam component 2 to rotate; all crossbeam components 2 located on the first side of the active end are located at the first driven end, and the crossbeam components 2 located at the first driven end are connected to the crossbeam components 2 located at the active end via a first transmission beam 241; wherein, the first transmission beam 241 includes m segments of first transmission sub-beams, and the cross-sectional area of ​​the first transmission sub-beams gradually increases from the m-th level first driven end to the 1st level first driven end; all crossbeam components 2 located on the second side of the active end are located at the second driven end, and the crossbeam components 2 located at the second driven end are connected to the crossbeam components 2 located at the active end via a second transmission beam 242; the second transmission beam 242 includes n segments of second transmission sub-beams, and the cross-sectional area of ​​the second transmission sub-beams gradually increases from the n-th level second driven end to the 1st level second driven end.

[0084] In the multi-row flexible tracking photovoltaic bracket of this application, the crossbeam assembly 2 located at the active end can drive all the crossbeam assemblies 2 located at the first driven end to rotate in linkage through the first transmission beam 241 and the second transmission beam 242 respectively, and all the crossbeam assemblies 2 located at the second driven end to rotate in linkage. That is, at least three adjacent support assemblies 1 in the second direction can be driven by a drive assembly 3 to achieve linkage rotation. Therefore, the tracking effect of the flexible tracking photovoltaic bracket 100 can be improved while reducing the application of drive assembly 3.

[0085] Furthermore, at the first driven end, from the m-th stage first driven end to the 1-th stage first driven end, the cross-sectional area of ​​the first transmission sub-beam gradually increases, offsetting the torque accumulation from the m-th stage first driven end to the 1-th stage first driven end, thereby improving the transmission stability of the first transmission beam 241, such as... Figure 3 As shown. Similarly, at the second driven end, from the nth stage second driven end to the 1st stage second driven end, the cross-sectional area of ​​the second transmission beam gradually increases, offsetting the torque accumulation from the nth stage second driven end to the 1st stage second driven end, thereby improving the transmission stability of the second transmission beam 242, as shown. Figure 3 As shown.

[0086] Specifically, in some embodiments, from the m-th level first driven end to the 1st level first driven end, the width of the first transmission sub-beam 241 remains constant, while its height gradually increases; all the crossbeam assemblies 2 located on the second side of the driving end are located at the second driven end, and from the n-th level second driven end to the 1st level second driven end, the width of the second transmission sub-beam 242 remains constant, while its height gradually increases. In some embodiments, from the m-th level first driven end to the 1st level first driven end, the width of the first transmission sub-beam 241 increases, while its height remains constant; all the crossbeam assemblies 2 located on the second side of the driving end are located at the second driven end, and from the n-th level second driven end to the 1st level second driven end, the width of the second transmission sub-beam 242 increases, while its height gradually remains constant.

[0087] Furthermore, from the first driven end of the first stage to the first driven end of the m-th stage, the cross-sectional area of ​​the first transmission sub-beam 241 gradually decreases; similarly, from the second driven end of the first stage to the second driven end of the n-th stage, the cross-sectional area of ​​the second transmission sub-beam 242 gradually decreases. Further, the cross-sectional area of ​​the first transmission sub-beam 241 corresponding to the first driven end of the m-th stage is the same as the cross-sectional area of ​​the second transmission sub-beam 242 corresponding to the second driven end of the n-th stage.

[0088] It should be explained that the first direction is the extension direction of the flexible tracking photovoltaic bracket 100, the second direction is the arrangement direction of the flexible tracking photovoltaic bracket 100, and the third direction is the height direction of the flexible tracking photovoltaic bracket 100. Among them, the first direction, the second direction, and the third direction are perpendicular to each other.

[0089] At least three adjacent support components 1 in the first direction can be understood as at least three adjacent support components 1 in the same row of flexible tracking photovoltaic brackets 100; at least three adjacent crossbeam components 2 in the first direction can be understood as two adjacent support components 1 in the same row of flexible tracking photovoltaic brackets 100; two adjacent support components 1 in the second direction can be understood as two adjacent support components 1 in at least three rows of flexible tracking photovoltaic brackets 100; at least three adjacent crossbeam components 2 in the second direction can be understood as two adjacent support components 1 in at least three rows of flexible tracking photovoltaic brackets 100.

[0090] The reduction of the drive assembly 3 in this application exists between at least three adjacent support assemblies 1 in the second direction, for example, three, four, five, six, etc.; taking three as an example, one support assembly 1 (crossbeam assembly 2) located in the middle is located at the power end, one support assembly 1 (crossbeam assembly 2) located on the first side is located at the first power end, and one support assembly 1 (crossbeam assembly 2) located on the second side is located at the second power end. Taking four as an example, one support assembly 1 (crossbeam assembly 2) located in the middle is located at the power end, two support assemblies 1 (crossbeam assembly 2) located on the first side are located at the first power end, and one support assembly 1 (crossbeam assembly 2) located on the second side is located at the second power end; or one support assembly 1 (crossbeam assembly 2) located on the first side is located at the first power end, and two support assemblies 1 (crossbeam assembly 2) located on the second side are located at the second power end. Taking five as an example, one support assembly 1 (crossbeam assembly 2) located in the middle is located at the power end, two support assemblies 1 (crossbeam assembly 2) located on the first side are located at the first power end, and two support assemblies 1 (crossbeam assembly 2) located on the second side are located at the second power end. Taking four as an example, one support component 1 (crossbeam component 2) located in the middle is located at the power end, three support components 1 (crossbeam components 2) located on the first side are located at the first power end, and two support components 1 (crossbeam components 2) located on the second side are located at the second power end; or two support components 1 (crossbeam components 2) located on the first side are located at the first power end, and three support components 1 (crossbeam components 2) located on the second side are located at the second power end.

[0091] Furthermore, each row of flexible tracking photovoltaic brackets 100 in the multi-row flexible tracking photovoltaic bracket may include at least two spans, each span corresponding to two support components 1; for a row of flexible tracking photovoltaic brackets 100, there are at least three support components 1, with two support components 1 located at the ends and at least one support component 1 located in the middle.

[0092] In a multi-row flexible tracking photovoltaic (PV) bracket system, the spans of the multiple rows of flexible tracking PV brackets 100 can be consistent or inconsistent. When the spans are consistent, the support components 1 in the multiple rows of flexible tracking PV brackets 100 are all aligned one-to-one in the second direction; or at least some of the support components 1 located in the middle of the multiple rows of flexible tracking PV brackets 100 are aligned one-to-one in the second direction. When the spans are inconsistent, at least some of the support components 1 located in the middle of the multiple rows of flexible tracking PV brackets 100 are aligned one-to-one in the second direction. In both cases, any one-to-one aligned support components 1 can be considered as multiple adjacent support components 1 in the second direction.

[0093] Overall, the support components 1 at the ends of the multi-row flexible tracking photovoltaic bracket 100 are all equipped with drive components 3. The support components 1 in the middle can be equipped with drive components 3 as needed, and the determination method can be based on the above situation.

[0094] Furthermore, the aforementioned first transmission beam 241 and second transmission beam 242 can be directly or indirectly connected to the corresponding crossbeam assembly 2. Taking indirect connection as an example, both the first transmission beam 241 and the second transmission beam 242 are connected to the crossbeam assembly 2 located at the active end through the first transmission rod 210; the first transmission sub-beam is connected to the corresponding crossbeam assembly 2 through the second transmission rod 220; and the second transmission sub-beam is connected to the corresponding crossbeam assembly 2 through the third transmission rod (not shown).

[0095] See Figures 4 to 6 The first transmission rod 210 is detachably connected to the corresponding crossbeam assembly 2, for example, by fasteners; or the first transmission rod 210 is non-detachably connected to the corresponding crossbeam assembly 2, for example, by welding. The first transmission rod 210 and the corresponding crossbeam assembly 2 are directly or indirectly connected.

[0096] To improve the versatility of the various components in this application, the first transmission rod 210 is detachably connected to the corresponding crossbeam assembly 2 via other components. Specifically, the multi-row flexible tracking photovoltaic bracket also includes a first transmission connector 250, and the first end of the first transmission rod 210 is connected to the corresponding crossbeam assembly 2 via the first transmission connector 250.

[0097] Similarly, the second transmission rod 220 and the third transmission rod are detachably connected to the corresponding crossbeam assembly 2, for example, by fasteners; or the second transmission rod 220 and the third transmission rod are non-detachably connected to the corresponding crossbeam assembly 2, for example, by welding. The second transmission rod 220 and the third transmission rod are directly or indirectly connected to the corresponding crossbeam assembly 2. Specifically, the first end of the second transmission rod 220 and the first end of the third transmission rod are connected to the corresponding crossbeam assembly 2 through the second transmission connector 260.

[0098] The above describes the connection relationships between the first transmission rod 210, the second transmission rod 220, and the third transmission rod and their corresponding crossbeam assemblies 2. Furthermore, considering that the position of the crossbeam assembly 2 is offset relative to the axis of the support assembly 1 after the drive assembly 3 is installed on the support assembly 1, the following definition is made to compensate for this offset. For ease of understanding, this application defines the following: Along the first direction, the first transmission connector 250 has a first connection surface connected to the corresponding crossbeam assembly 2, and the first transmission connector 250 has a second connection surface connected to the first transmission rod 210; the second transmission connector 260 has a first connection surface connected to the corresponding crossbeam assembly 2, and the second transmission connector 260 has a second connection surface connected to the second transmission rod 220 or the third transmission rod.

[0099] The distance L1 between the first connecting surface and the second connecting surface of the first transmission connector 250 and the distance L2 between the first connecting surface and the second connecting surface of the second transmission connector 260 satisfy L1 < L2; and the distance between the first transmission rod 210 and the second transmission rod 220 and the axis of the corresponding support component 1 is greater than the diameter of the support component 1.

[0100] See Figure 7 The first transmission connector 250 includes a transmission connecting plate 251, a first connecting support plate 252, and a second connecting support plate 253. The first connecting support plate 252 and the second connecting support plate 253 extend from both ends of the transmission connecting plate 251 toward the crossbeam assembly 2. The transmission connecting plate 251 is connected to the first transmission rod 210 via a first fastener 254, and the first connecting support plate 252 and the second connecting support plate 253 are connected to the crossbeam assembly 2 via the first fastener 254. It can be seen that the first transmission connector 250 of the above structure forms a trapezoidal groove structure. On the one hand, it enables the connection between the first transmission rod 210 and the crossbeam assembly 2. On the other hand, the trapezoidal groove structure, due to its groove structure, gives the first transmission connector 250 rotational elasticity, thereby improving the rebound capability of the connection between the first transmission connector 250 and the first transmission rod 210, and extending the fault tolerance during linkage rotation.

[0101] See Figure 8 The second transmission connector 260 includes a transmission connector 261, a first connecting branch 262, and a second connecting branch 263. One end of the first connecting branch 262 and the second connecting branch 263 is connected to the crossbeam assembly 2 via a second fastener 264. The other end of the first connecting branch 262 and the second connecting branch 263 is connected to the transmission connector 261, forming a space between them to accommodate the second transmission rod 220. The transmission connector 261 is connected to the sixth mounting hole 225 on the second transmission rod 220 via the second fastener 264.

[0102] It should be noted that any of the aforementioned transmission connecting plate 251, first connecting support plate 252, second connecting support plate 253, transmission connecting part 261, first connecting support 262, and second connecting support 263 is a plate-like structure, a U-shaped structure formed by folding, or an I-shaped structure. In a preferred arrangement, the transmission connecting plate 251, first connecting support plate 252, and second connecting support plate 253 are plate-like structures, while the transmission connecting part 261, first connecting support 262, and second connecting support 263 are U-shaped or I-shaped structures formed by folding. This arrangement ensures that the rigidity of the first transmission connecting member 250 connected to the first transmission rod 210 is less than the rigidity of the second transmission connecting member 260 connected to the second transmission rod 220, thereby reasonably coordinating the corresponding rigidity for different stress conditions.

[0103] The third transmission rod is rotatably connected to the second end of the first transmission rod 210 and the second end of the second transmission rod 220. Any structure that can achieve the above connection method is within the protection scope of this application.

[0104] To improve the assembly efficiency of the first transmission rod 210, second transmission rod 220, third transmission rod, first transmission beam, and second transmission beam, these components are non-detachable but rotatable connections. To improve transportation efficiency and the versatility of components, the first transmission rod 210, second transmission rod 220, third transmission rod, first transmission beam, and second transmission beam are detachable but rotatable connections.

[0105] Specifically, the second end of the first transmission rod 210 is provided with a first rotating member (not shown), and the first transmission rod 210 is rotatably connected to the first transmission beam and the second transmission beam through the first rotating member; the second transmission rod and the third transmission rod also include a second rotating member (not shown), and the second transmission rod 220 and the third transmission rod 230 are rotatably connected to the corresponding first transmission sub-beam and the second transmission sub-beam through the second rotating member.

[0106] The first rotating component may include two first rotating plates 211 and a first pin 213. The two first rotating plates 211 are arranged opposite to each other, with one end fixed to the second end of the first transmission rod 210 through a fourth mounting hole 214. The first pin 213 is disposed at the other end of the first rotating plate 211 for rotatable connection with the first transmission beam and the second transmission beam. When assembly is required, the first rotating plate 211 can be installed on the second end of the first transmission rod 210 by means of a fifth fastener 212, and then rotatable connection with the first transmission beam and the second transmission beam can be achieved by means of the first pin 213.

[0107] The second rotating component may include two second rotating plates 221 and a second pin 223. The two second rotating plates 221 are arranged opposite to each other, with one end fixed to the second end of the second transmission rod 220 through a fifth mounting hole 224. The second pin 223 is disposed at the other end of the second rotating plate 221 for rotatable connection with the corresponding first and second transmission sub-beams. When assembly is required, the second rotating plate 221 can be installed on the second end of the second transmission rod 220 using a sixth fastener 222, and then rotatable connection with the corresponding first and second transmission sub-beams can be achieved using the second pin 223.

[0108] To further enhance the torque resistance of the crossbeam assembly 2 located at the first driven end and / or the second driven end, the multi-row flexible tracking photovoltaic support also includes a damping element 270. One end of the damping element 270 is rotatably mounted on the crossbeam assembly 2, and the other end is rotatably mounted on the support assembly 1, providing buffering force during the rotation of the crossbeam assembly 2 and reducing vibration. The damping element 270 can directly "support" most or even all of the weight of the crossbeam assembly 2 located at the driven end, reducing the instantaneous load on the second transmission rod 220. Furthermore, by providing a pressure loss protection function, for example, when the transmission between the first transmission rod 210 and the second transmission rod 220 at the active end breaks, the damping element 270 can act like a "safety rope" to firmly support the crossbeam assembly 2 located at the driven end, preventing it from rapidly deflecting due to its own weight. This ensures that the multi-row flexible tracking photovoltaic support can still operate partially or fully normally even in the event of transmission failure.

[0109] One end of the damping element 270 is mounted on the crossbeam assembly 2 via a connecting support 273, and the other end of the damping element 270 is mounted on the support assembly 1 via a clamp 272. The clamp 272 is provided with a connecting hole 271, through which it is rotatably connected to the damping element 270.

[0110] The structure described above describes the linkage of at least three adjacent crossbeam assemblies 2 in the second direction. Since a row of flexible tracking photovoltaic brackets 100 may include multiple crossbeam assemblies 2, when there are more than three crossbeam assemblies 2, at least three crossbeam assemblies 2 are located at the ends, and at least one crossbeam assembly 2 is located in the middle; similarly, two support assemblies 1 are located at the ends, and at least one support assembly 1 is located in the middle. In order to improve the tracking capability of at least three rows of flexible tracking photovoltaic brackets 100, the support assemblies 1 located at the ends are all provided with drive assemblies 3; while in the support assemblies 1 located in the middle, among the two support assemblies 1 adjacent in the second direction, one is provided with a drive assembly 3, and the other is not provided with a drive assembly 3.

[0111] Alternatively, one row of flexible tracking photovoltaic brackets 100 may have drive components 3 arranged in the middle of the support components 1, while the other row of flexible tracking photovoltaic brackets 100 may have no drive components 3 arranged in the middle of the support components 1.

[0112] See Figure 9 and Figure 10 To improve the wind resistance of this multi-row flexible tracking photovoltaic (PV) support system, a wind-resistant component 5 is also included. The wind-resistant component 5 is mounted on the main cable assembly 4 of the flexible tracking PV support system 100. The main cable assembly 4 includes two parallel main cables 41 used for mounting the PV modules. This multi-row flexible tracking PV support system may include at least one span, and each span may be equipped with at least one wind-resistant component 5. For example, if one wind-resistant component 5 is installed per span:

[0113] The wind-resistant component 5 includes two stabilizing cables 52 and a wind-resistant frame 51. The two stabilizing cables 52 are located below the main cables 41, and their two ends are fixed to the crossbeam assembly 2. The wind-resistant frame 51 has a first side and a second side arranged opposite to each other. The first side of the wind-resistant frame 51 is connected to each of the main cables 41, and the second side of the wind-resistant frame 51 is connected to the stabilizing cables 52. This forms an integrated spatial structure, improving the overall stability of the flexible photovoltaic tracking bracket. It can effectively resist the torsion and collision of photovoltaic modules by wind loads, snow loads, and gravity loads, reducing the risk of damage to photovoltaic modules due to wind force, and also reducing the risk of photovoltaic modules developing hidden cracks and overturning.

[0114] The stabilizing cables 52 can be of two types, or one, three, four, or more, to improve the overall stability of the flexible photovoltaic tracking bracket. Preferably, two stabilizing cables 52 are used, and the two stabilizing cables 52 are respectively located below the two main cables 41, so that the first side of the wind-resistant frame 51 can be rigidly connected to the two main cables 41, and the second side of the wind-resistant frame 51 can be rigidly connected to the two stabilizing cables 52, thereby forming a spatial cage structure, which can improve the overall stability of the flexible photovoltaic tracking bracket.

[0115] To prevent the wind-resistant frame 51 from undergoing vertical displacement due to wind suction and wind lifting, the wind-resistant component 5 also includes two wind-resistant cables 53. The two ends of the two wind-resistant cables 53 are respectively connected to the crossbeam component 2, and the two wind-resistant cables 53 are arranged crosswise and connected to the second side of the wind-resistant frame 51. In the figure, the wind-resistant cables 53 located between the wind-resistant frame 51 and one crossbeam component 2 are arranged crosswise, and the wind-resistant cables 53 located between the wind-resistant frame 51 and another crossbeam component 2 are arranged crosswise.

[0116] The crisscrossing wind-resistant cables 53 provide strong resistance to lateral forces: when wind blows from one side, it attempts to push the crossbeam assembly to one side (causing lateral displacement). The crisscrossing wind-resistant cables 53 react immediately: the cable 53 on the leeward side is tightened, bearing a huge tensile force, acting like a diagonal brace to prevent the crossbeam assembly 2 and the wind-resistant frame 51 from moving further; while the cable 53 on the windward side is relaxed. This "tightening and relaxing" mechanism effectively converts horizontal wind force into axial tension within the wind-resistant cables 53, and transmits the force to the foundation of the entire structure through anchor points. This is far more efficient than relying solely on the bending stiffness of the crossbeam assembly 2 and the wind-resistant frame 51 to resist wind forces.

[0117] Compared to parallel arrangement, using a cross-arrangement of wind-resistant cables 53 increases the sag-to-span ratio of the wind-resistant cables 53, thereby improving the torsional resistance of the double-row flexible tracking photovoltaic support 100. For example... Figure 8 As shown in the diagram, in the plane containing the first and third directions, the rise-to-span ratio is m2 / m1, where m2 is the height of the wind-resistant frame 51 in the first direction and m1 is the span in the first direction. In the plane containing the first and second directions, the rise-to-span ratio is m3 / m1, where m3 is the distance between the two connection points of the cross-arranged wind-resistant cables 53 on the wind-resistant frame 51 and m1 is the span in the first direction. In the parallel arrangement of the wind-resistant cables 53, the rise-to-span ratio is m2 / m1 in the plane containing the first and third directions. Therefore, compared with the parallel arrangement, the cross-arrangement of the wind-resistant cables 53 increases the rise-to-span ratio of the wind-resistant cables 53, thereby improving the torsional resistance of the double-row flexible tracking photovoltaic support 100.

[0118] Furthermore, when the wind-resistant cables 53 are arranged in a crisscross pattern, the greater the distance between the two connection points of the crisscrossed wind-resistant cables 53 on the wind-resistant frame 51, the greater their sag-to-span ratio. As described above, the height of the wind-resistant frame 51 in the first direction is relatively fixed. The factor affecting the sag-to-span ratio of the double-row flexible tracking photovoltaic support 100 is the distance between the two connection points of the crisscrossed wind-resistant cables 53 on the wind-resistant frame 51. The larger this distance m3, the greater the sag-to-span ratio, resulting in greater rigidity and stability of the double-row flexible tracking photovoltaic support 100, and thus stronger torsional resistance of the wind-resistant cables 53. Therefore, when the two connection points of the crisscrossed wind-resistant cables 53 on the wind-resistant frame 51 are located on the outermost side of the wind-resistant frame 51 in the second direction, the stiffness of the wind-resistant cables 53 is maximized.

[0119] A geometrically invariant system is formed, reducing deformation: the intersecting wind-resistant cables 53, together with the crossbeam assembly 2 and the wind-resistant frame 51, form a stable triangular structure (because a triangle is a stable geometric shape). This system greatly reduces the horizontal displacement (lateral movement) and vertical vibration (swaying) of the crossbeam assembly 2 and the wind-resistant frame 51 under wind loads, as well as overturning / torsion, making the entire structure more stable. For structures requiring high precision or high safety, such as bridges, crane booms, and radio towers, controlling deformation is crucial.

[0120] Mitigating Wind-Induced Vibration (Vortex-Induced Vibration): When wind passes around a bluff body (a blunt body, such as beam assembly 2 and wind-resistant frame 51), it generates alternating vortices, causing vibrations perpendicular to the wind direction, known as vortex-induced vibration. The cross-bracing cables 53 mitigate this vibration in two ways: Changing the structural frequency: This increases the overall stiffness of the system, thereby raising its natural frequency and making it more difficult for the wind to induce vibrations. Increasing damping: The wind-resistant cables 53 themselves and their connection points provide external damping, helping to dissipate vibrational energy and causing the vibration to decay more quickly.

[0121] To prevent the wind-resistant frame 51 from vertically displacing due to wind suction and uplift, the wind-resistant component 5 may also include an anti-arch cable 54 and a vertical tension cable 516. Both ends of the anti-arch cable 54 are connected to the support component 1, and one end of the vertical tension cable 516 is connected to the first side of the wind-resistant frame 51. The other end of the vertical tension cable 516 is connected to the anti-arch cable 54, causing the middle of the anti-arch cable 54 to arch upwards. This restricts the vertical displacement of the wind-resistant frame 51 caused by wind suction and uplift, while freeing up space below the photovoltaic modules of the flexible photovoltaic tracking bracket, improving the space utilization rate under the photovoltaic modules, and increasing the span of the flexible photovoltaic tracking bracket. Furthermore, under downward loads such as gravity loads, snow loads, and wind pressure, the vertical tension cable 516 and the anti-arch cable 54 exhibit a compression tendency, preventing the generation of internal forces in the photovoltaic system and not affecting the rotation of the wind-resistant frame 51.

[0122] It should be noted that the two ends of the anti-arch cable 54 can be connected to the ground or to the support components 1 at both ends of the main cable assembly 4. Preferably, the two ends of the anti-arch cable 54 are connected to the support components 1 to improve the convenience of construction. The anti-arch cable 54 can be connected to the support components 1 in the form of ear plates or clamps 12.

[0123] As can be seen from the above embodiments, the rotation of the crossbeam assembly 2 drives the photovoltaic modules on the main cable 41 to rotate, thereby adjusting the angle of the photovoltaic modules to ensure a larger effective light-receiving area. In addition, the spatial cage structure improves the overall stability of the flexible photovoltaic tracking bracket. At the same time, the wind-resistant frame 51 is connected to the anti-arch cable 54 through the vertical cable 516, so that the middle part of the anti-arch cable 54 arches upward. While limiting the vertical displacement of the wind-resistant frame 51 caused by wind suction and wind lifting, it can improve the space utilization rate under the photovoltaic modules of the flexible photovoltaic tracking bracket and increase the span of the flexible photovoltaic tracking bracket.

[0124] The wind-resistant frame 51 described above in this application serves to connect the main cable 41, stabilizing cable 52, wind-resistant cable 53, anti-arch cable 54, etc. In some examples, the wind-resistant frame 51 includes an upper chord 511, a lower chord 512, and a connecting chord 513. The upper chord 511 and the lower chord 512 are arranged in parallel, and the two ends of the connecting chord 513 are respectively connected to one end of the upper chord 511 and one end of the lower chord 512. The upper chord 511, the lower chord 512, and the connecting chord 513 form at least one planar wind-resistant structure. The two ends of the upper chord 511 and / or the lower chord 512 are provided with first locking members 515 for locking the main cable 41, the stabilizing cable 52, or the wind-resistant cable 53.

[0125] The two ends of the main cable 41 are connected to the crossbeam assembly 2, and the middle part is connected to the locking member 515 of the upper chord 511; the two ends of the stabilizing cable 52 are connected to the crossbeam assembly 2, and the middle part is connected to the locking member 515 of the lower chord 512; the two ends of the wind-resistant cable 53 are connected to the crossbeam assembly 2, and after crossing, they are connected to the locking member 515 of the lower chord 512 to avoid the space occupied by the photovoltaic module during rotation; the two ends of the anti-arch cable 54 are connected to the crossbeam assembly 2 or the support assembly 1, and the middle part is connected to the upper chord 511 through the vertical cable 516.

[0126] The vertical cable 516 can be connected to the rotation center of the wind-resistant frame 51. When upward loads such as wind suction or wind lifting are applied, the upper node of the vertical cable 516 will not shift when the wind-resistant frame 51 rotates with the main cable 41. This allows the vertical cable 516 to only provide vertical restraint to the wind-resistant frame 51 and prevents external torque caused by the rotation of the wind-resistant frame 51. Specifically, the vertical cable 516 can be connected to the rotation center at the midpoint of the upper chord 511. One end of the vertical cable 516 can be connected to the rotation center of the upper chord 511 via a U-shaped shackle, while the other end of the vertical cable 516 can be connected to the wind-resistant cable via a connector.

[0127] The above describes the connection relationship between the wind-resistant frame 51 and each cable. Furthermore, the upper chord 511 and the connecting chord 513, and / or the lower chord 512 and the connecting chord 513, are connected by wind-resistant connectors 517. The wind-resistant connectors 517 used to connect the upper chord 511 and the connecting chord 513, and the wind-resistant connectors 517 used to connect the lower chord 512 and the connecting chord 513, can be components of different or the same structure. Using components of the same structure improves the adaptability of the parts and reduces mold costs.

[0128] A connection point may be formed during the connection process between the upper chord 511 and the connecting chord 513, and / or between the lower chord 512 and the connecting chord 513. Figure 8 The structure includes two upper chords 511 and one lower chord 512. The wind-resistant frame 51 has eight connection points, and each connection point can be equipped with a wind-resistant connector 517. The connection between the two corresponding chords is achieved through the wind-resistant connector 517.

[0129] Since the lower chord 512 needs to be connected to four connecting chords 513, this application can also integrate the connection points for connecting the lower chord 512 to the two connecting chords 513. That is, the wind-resistant connector 517 arranged on the lower chord 512 can include two connection positions, one for connecting one connecting chord 513 and the other for connecting another connecting chord 513. This reduces the number of wind-resistant connectors 517 used.

[0130] Furthermore, the wind-resistant connector 517 used to connect the upper chord 511 and the connecting chord 513 may also include two connection positions. Therefore, the wind-resistant connector 517 of this application can be a universal component. When the wind-resistant connector 517 is arranged on the upper chord 511, the operator can select one connection position to connect with the corresponding connecting chord 513. When the wind-resistant connector 517 is arranged on the lower chord 512, the operator can select one connection position to connect with one corresponding connecting chord 513, and the other connection position to connect with the other corresponding connecting chord 513. In other words, the aforementioned wind-resistant connector 517 of this application is a standard component. On the one hand, this reduces the time wasted due to marking installation positions during the assembly of the wind-resistant frame 51, improving the assembly efficiency of the wind-resistant frame 51; on the other hand, since multiple wind-resistant connectors 517 are required during the assembly of the wind-resistant frame 51, designing them as standard components reduces mold opening costs.

[0131] For details, see Figures 11 to 13The wind-resistant connector 517 includes a U-shaped clip 5171 and two connecting lugs 5172. The two connecting lugs 5172 are arranged opposite to each other on the U-shaped clip 5171, and a locking position 5173 for accommodating the connecting chord 513 is formed between the two connecting lugs 5172. The locking position 5173 includes two connecting positions. The U-shaped clip 5171 is detachably or non-detachably connected to the upper chord 511 or the lower chord 512; and / or, the locking position 5173 is detachably or non-detachably connected to the connecting chord 513.

[0132] Taking the detachable type as an example, both the U-shaped clip 5171 and the two connecting lugs 5172 are provided with two sets of second mounting holes 51721 for mounting the fourth fastener 51724. One set of second mounting holes corresponds to one connection position, and the other set of second mounting holes corresponds to another connection position. When it is necessary to assemble the upper chord 511 and the connecting chord 513, the position to be installed on the upper chord 511 is clipped into the U-shaped groove 51711 of the U-shaped clip 5171, and the fourth fastener 51724 passes through the second mounting hole 51721 to achieve the initial connection between the U-shaped clip 5171 and the upper chord 511. One end of the connecting chord 513 is placed in the clip 5173. After adjusting the angle, the fourth fastener 51724 passes through the second mounting hole 51721 to achieve the initial connection between the U-shaped clip 5171 and the connecting chord 513, thereby realizing the assembly of the upper chord 511 and the connecting chord 513.

[0133] When it is necessary to assemble the lower chord 512 and the connecting chord 513, the position to be installed of the lower chord 512 is locked in the U-shaped groove 51711 of the U-shaped clip 5171, and the third fastener 51713 passes through the first mounting hole 51712 to achieve the initial connection between the U-shaped clip 5171 and the lower chord 512. One end of the connecting chord 513 is placed in the locking position 5173, and after adjusting the angle, the third fastener 51713 passes through the first mounting hole 51721 to achieve the initial connection between the U-shaped clip 5171 and the connecting chord 513, thereby realizing the assembly of the lower chord 512 and the connecting chord 513.

[0134] To further improve the adaptability of the aforementioned U-shaped clip 5171 and reduce the number of second locking members 5174 arranged on the upper chord 511 or lower chord 512, one of the two connecting side ears 5172 is provided with a second locking member 5174 for locking the main cable 41, the stabilizing cable 52, or the wind-resistant cable. Specifically, the two connecting side ears 5172 are provided with a third mounting hole 51722 for installing the second locking member 5174; the other of the two connecting side ears 5172 is provided with a clearance notch 51723 to avoid the second locking member 5174.

[0135] It should be noted that the number of upper chord members 511 is one, the number of lower chord members 512 is one, and the number of connecting chord members 513 is two. This configuration forms a planar wind-resistant structure. Alternatively, in some embodiments, there are two upper chord members 511 arranged in parallel; one lower chord member 512; and four connecting chord members 513. The two upper chord members 511, one lower chord member 512, and four connecting chord members 513 respectively form two planar wind-resistant structures, arranged in a V-shape. Or, in some embodiments, there is one upper chord member 511; two lower chord members 512; and four connecting chord members 513. The one upper chord member 511, two lower chord members 512, and four connecting chord members 513 respectively form two planar wind-resistant structures, arranged in an inverted V-shape.

[0136] When the wind-resistant frame 51 includes at least four connecting chords 513, adjacent connecting chords 513 are connected by reinforcing chords 514 to form a stable triangular structure, thereby improving the wind resistance of the wind-resistant frame 51.

[0137] It should be noted that the first fastener 254, the second fastener 264, the third fastener 51713, the fourth fastener 51724, the fifth fastener 212, and the sixth fastener 222 mentioned above can be understood as fasteners such as bolts and screws. The first locking member 515 and the second locking member 5174 can both be understood as structures used to fasten various ropes. They have an overall U-shaped structure, with the two locking arms of the locking member passing through corresponding mounting holes and being installed on the structural component to be installed via nuts, thus achieving the locking of the corresponding rope. The two are interchangeable.

[0138] See Figure 14 and Figure 15 In a row of flexible tracking photovoltaic brackets 100, the crossbeam assembly 2 on the support assembly 1 at the end includes a crossbeam 21, on which a first locking member 22 for installing the main cable, a second locking member 23 for installing the stabilizing cable, and a third locking member 24 for installing the wind-resistant cable are provided.

[0139] In addition, the beam assembly 2 also includes a reinforcing member 28, which can improve the torsional resistance of the beam assembly 2.

[0140] In the diagram, the reinforcing member includes a first reinforcing arm 281 and a second reinforcing arm 282. One end of the first reinforcing arm 281 is connected to one end of the second reinforcing arm 282, and the other ends of the first reinforcing arm 281 and the second reinforcing arm 282 are respectively connected to the crossbeam assembly 2; and / or, the reinforcing member includes a first reinforcing arm 281, a second reinforcing arm 282 and a third reinforcing arm 283. One end of the first reinforcing arm 281 is connected to one end of the second reinforcing arm 282, and the other ends of the first reinforcing arm 281 and the second reinforcing arm 282 are respectively connected to the crossbeam assembly 2; the third reinforcing arm 283 is located within the space enclosed by the first reinforcing arm 281 and the second reinforcing arm 282, one end of the third reinforcing arm 283 is connected to the crossbeam assembly 2, and the other end of the third reinforcing arm 283 is connected to one end of the first reinforcing arm 281 and the second reinforcing arm 282.

[0141] The first reinforcing arm 281, the second reinforcing arm 282 and / or the third reinforcing arm 283 are plate-shaped structures, folded reinforcing structures (U-shaped or I-shaped), and rectangular tube structures.

[0142] To further improve the wind resistance of the flexible tracking photovoltaic bracket 100, in a row of flexible tracking photovoltaic brackets 100, the crossbeam assembly 2 on the end support assembly 1 also includes a cable tie 6. The cable tie 6 includes a cable tie 61, one end of which is connected to the support assembly 1, and the other end of which is connected to the fixed base 65.

[0143] The support assembly 1 includes a column and a support 11. The column is used to be embedded in the road surface or connected to precast piles on the road surface. The support 11 is located on top of the column for mounting the crossbeam assembly 2 and / or drive assembly 3. When the column is at its end, the support 11 is also provided with an outwardly extending cable lug 13 for mounting the stay cable 61. The first connecting end 62 of the stay cable 61 is detachably arranged in the cable lug 13, and the second connecting end 63 of the stay cable 61 is detachably arranged on a rotating seat 64, which can be fixed to a fixed base 65.

[0144] Furthermore, the rotating seat 64 is rotatably mounted on the fixed base 65 to balance the tension of the stay cable 61 and reduce the time required for angle adjustment.

[0145] The terms "first" and "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
