[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 on all support components.

[0071] The core of this application is to provide a double-row flexible tracking photovoltaic bracket, which improves the tracking effect of the flexible tracking photovoltaic bracket while reducing the application of drive components.

[0072] 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.

[0073] See Figures 1 to 3A double-row flexible tracking photovoltaic support 100 includes two rows of flexible tracking photovoltaic supports 100 and a transmission mechanism 200. The two rows of flexible tracking photovoltaic supports 100 extend along a first direction and are arranged side-by-side in a second direction, which is perpendicular to the first direction. Each row of flexible tracking photovoltaic supports 100 includes a support component 1 and a crossbeam component 2, with the crossbeam component 2 rotatably mounted on the support component 1. In two adjacent support components 1 in the second direction, one of the support components 1 is provided with a driving component 3 to drive the corresponding crossbeam component 2 to rotate. The corresponding crossbeam components 2 on the two support components 1 are connected by the transmission mechanism 200 to achieve synchronized rotation of the corresponding crossbeam components 2 on the two adjacent support components 1.

[0074] In the double-row flexible tracking photovoltaic bracket 100 of this application, in each pair of adjacent support components 1 of the two rows of flexible tracking photovoltaic brackets 100, one of the two support components 1 is provided with a drive component 3 to drive the corresponding crossbeam component 2 to rotate; the corresponding crossbeam components 2 on the two support components 1 are connected by a transmission mechanism 200 to realize the linkage rotation of the corresponding crossbeam components 2 on the two adjacent support components 1. It can be seen that by using the double-row flexible tracking photovoltaic bracket 100 of this application, the linkage rotation of two adjacent crossbeam components 2 can be realized by a single drive component 3. Therefore, the tracking effect of the flexible tracking photovoltaic bracket 100 can be improved while reducing the application of drive components 3.

[0075] 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.

[0076] Two adjacent support components 1 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 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 two rows of flexible tracking photovoltaic brackets 100; two adjacent crossbeam components 2 in the second direction can be understood as two adjacent support components 1 in two rows of flexible tracking photovoltaic brackets 100.

[0077] The reduction of the drive component 3 in this application exists between adjacent support components 1 in the second direction. For example, if one support component 1 is provided with the drive component 3, the other support component 1 is not provided with the drive component 3, and the two support components 1 achieve linkage rotation through the transmission mechanism 200.

[0078] Furthermore, each row of flexible tracking photovoltaic brackets 100 in the double-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.

[0079] In a double-row flexible tracking photovoltaic (PV) system, the spans of the two rows of flexible tracking PV brackets 100 can be identical or inconsistent. When the spans are identical, the support components 1 in one row of flexible tracking PV brackets 100 are aligned one-to-one with the support components 1 in the other row of flexible tracking PV brackets 100 in the second direction; or, at least some of the support components 1 located in the middle of one row of flexible tracking PV brackets 100 are aligned one-to-one with the support components 1 located in the middle of the other row of flexible tracking PV brackets 100 in the second direction. When the spans are inconsistent, at least some of the support components 1 located in the middle of one row of flexible tracking PV brackets 100 are aligned one-to-one with the support components 1 located in the middle of the other row of flexible tracking PV brackets 100 in the second direction. In both cases, any support components 1 that are aligned one-to-one can be considered as two adjacent support components 1 in the second direction.

[0080] Overall, the support components 1 at the ends of the two rows of flexible tracking photovoltaic brackets 100 are equipped with drive components 3, and the support components 1 in the middle can be equipped with drive components 3 as needed, and the determination method can be determined according to the above situation.

[0081] The transmission mechanism 200 may include a first transmission rod 210, a second transmission rod 220 and a third transmission rod 230. The first end of the first transmission rod 210 is used to connect with the corresponding crossbeam assembly 2. The first end of the second transmission rod 220 is used to connect with the corresponding crossbeam assembly 2. The first end of the third transmission rod 230 is rotatably connected to the second end of the first transmission rod 210 and the second end of the third transmission rod 230 is rotatably connected to the second end of the second transmission rod 220.

[0082] Taking a crossbeam assembly 2 equipped with a drive component 3 and equipped with a first transmission rod 210, and another crossbeam assembly 2 equipped with a second transmission rod 220 as an example, when the drive component 3 drives the corresponding crossbeam assembly 2 to rotate, the first transmission rod 210 follows the rotation of the crossbeam assembly 2, and the third transmission rod 230 drives the second transmission rod 220 to rotate with the first transmission rod 210, thereby driving the crossbeam assembly 2 corresponding to the second transmission rod 220 to rotate in linkage.

[0083] Taking a crossbeam assembly 2 equipped with a drive component 3 and equipped with a second transmission rod 220, and another crossbeam assembly 2 equipped with a first transmission rod 210 as an example, when the drive component 3 drives the corresponding crossbeam assembly 2 to rotate, the second transmission rod 220 follows the rotation of the crossbeam assembly 2, and the third transmission rod 230 drives the first transmission rod 210 to rotate following the second transmission rod 220, thereby driving the crossbeam assembly 2 corresponding to the first transmission rod 210 to rotate in linkage.

[0084] 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 can be directly or indirectly connected.

[0085] 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 transmission mechanism 200 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.

[0086] Similarly, the second transmission rod 220 is detachably connected to the corresponding crossbeam assembly 2, for example, by fasteners; or the second transmission rod 220 is non-detachably connected to the corresponding crossbeam assembly 2, for example, by welding. The second transmission rod 220 and the corresponding crossbeam assembly 2 are directly or indirectly connected. Specifically, the transmission mechanism 200 also includes a second transmission connector 260, through which the first end of the second transmission rod 220 is connected to the corresponding crossbeam assembly 2.

[0087] The above describes the connection relationship between the first transmission rod 210 and the second transmission rod 220 and the corresponding crossbeam assembly 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, to compensate for this offset, the following definition is made for ease of understanding: 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.

[0088] 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 assembly 1 is greater than the diameter of the support assembly 1. This description is based on the example of a beam assembly 2 corresponding to the first transmission rod 210 being equipped with a drive assembly 3 (the first transmission rod 210 is located at the active end, and the second transmission rod 220 is located at the driven end). Of course, in other examples of this application, the beam assembly 2 corresponding to the second transmission rod 220 may also be equipped with a drive assembly 3 (the second transmission rod 220 is located at the active end, and the first transmission rod 210 is located at the driven end), in which case L1 and L2 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 assembly 1 is less than the diameter of the support assembly 1.

[0089] The aforementioned drive assembly 3 may include a motor and a reducer, wherein the motor is driven by the reducer, and the reducer is driven by the corresponding crossbeam assembly 2 to drive the crossbeam assembly 2 to rotate relative to the support assembly 1. In the above connection method of the embodiments of this application, adjacent crossbeam assemblies 2 achieve coupled transmission, which not only reduces the use of motors but also reduces the application of reducers.

[0090] To clearly understand the above technical solution, the following explanation will take the first transmission rod 210 located at the active end as an example.

[0091] See Figure 4 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.

[0092] See Figure 5The 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.

[0093] 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.

[0094] The third transmission rod 230 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.

[0095] To improve the efficiency of the first transmission rod 210, the second transmission rod 220, and the third transmission rod 230, these three rods are non-detachable but rotatable connections. To improve transportation efficiency and the versatility of components, the first transmission rod 210, the second transmission rod 220, and the third transmission rod 230 are detachable but rotatable connections.

[0096] Specifically, the transmission mechanism 200 also includes a first rotating member (not shown), the first end of the first transmission rod 210 being connected to the corresponding crossbeam assembly 2 via the first rotating member; the transmission mechanism 200 also includes a second rotating member (not shown), the first end of the second transmission rod 220 being connected to the corresponding crossbeam assembly 2 via the second rotating member.

[0097] 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 third transmission rod 230. 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 third transmission rod 230 can be achieved by means of the first pin 213.

[0098] 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 third transmission rod 230. When assembly is required, the second rotating plate 221 can be installed on the second end of the second transmission rod 220 by means of a sixth fastener 222, and then rotatable connection with the third transmission rod 230 can be achieved by means of the second pin 223.

[0099] To further enhance the torque resistance of the beam assembly 2 at the driven end, the transmission mechanism 200 also includes a damping element 270. One end of the damping element 270 is rotatably mounted on the beam assembly 2, and the other end is rotatably mounted on the support assembly 1, providing buffering force during the rotation of the beam assembly 2 and reducing vibration. The damping element 270 can directly "support" most or even all of the weight of the beam assembly 2 at the driven end, reducing the instantaneous load on the second transmission rod 220. Furthermore, the damping element 270 has a pressure loss protection function. For example, if 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," firmly supporting the beam assembly 2 at the driven end and preventing it from rapidly deflecting due to its own weight. This ensures that the double-row flexible tracking photovoltaic bracket 100 can still operate partially or fully normally even in the event of transmission failure.

[0100] One end of the aforementioned 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 first clamp 272. The first clamp 272 is provided with a connecting hole 271, through which it is rotatably connected to the damping element 270.

[0101] The structure described above describes the linkage between two 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, two 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 the two 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 selected to be equipped with a drive assembly 3, and the other is selected not to be equipped with a drive assembly 3.

[0102] 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.

[0103] See Figure 6 and Figure 7 To improve the wind resistance of the double-row flexible tracking photovoltaic support 100, the double-row flexible tracking photovoltaic support 100 also includes a wind-resistant component 5. The wind-resistant component 5 is disposed on the main cable assembly 4 of the flexible tracking photovoltaic support 100. The main cable assembly 4 includes two parallel main cables 41, which are used to install the photovoltaic modules. The double-row flexible tracking photovoltaic support 100 may include at least one span, and each span may be provided with at least one wind-resistant component 5. Taking the example of providing one wind-resistant component 5 per span:

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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 7 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.

[0109] 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.

[0110] 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.

[0111] 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 bracing cables 53 themselves and their connection points provide additional damping, helping to dissipate vibrational energy and causing the vibration to decay more quickly.

[0112] 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.

[0113] 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 through ear plates or second clamps 12.

[0114] 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.

[0115] See Figure 8 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 a first locking member 515 for locking the main cable 41, the stabilizing cable 52, or the wind-resistant cable 53.

[0116] The two ends of the main cable 41 are connected to the crossbeam assembly 2, and the middle part is connected to the first 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 first 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 first 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.

[0117] 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 additional torque from being generated due to 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.

[0118] 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.

[0119] 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 6 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.

[0120] 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.

[0121] 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.

[0122] For details, see Figure 9 and Figure 10 The 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.

[0123] 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.

[0124] 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 51712 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.

[0125] To further improve the adaptability of the aforementioned U-shaped clip 5171 and reduce the number of second locking elements 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 element 5174 for locking the main cable 41, stabilizing cable 52, or wind-resistant cable 53. Specifically, each of the two connecting side ears 5172 is provided with a third mounting hole 51722 for installing the second locking element 5174; the other of the two connecting side ears 5172 is provided with a clearance notch 51723 to avoid the second locking element 5174.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] See Figure 11 and Figure 12 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, which is provided with 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; the crossbeam 21 is mounted on the support assembly 1 via a support 11.

[0130] In addition, the beam assembly 2 also includes a reinforcing member 28, which can improve the torsional resistance of the beam assembly 2.

[0131] 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.

[0132] 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.

[0133] 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 located at the end of the 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 cable lug 13 of the support assembly 1, and the other end of which is connected to the fixed base 65.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. 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.
