Description

[0001] This application claims priority to Chinese patent application filed on April 11, 2025, with application number 202520679158.X and entitled "A Flexible Tracking Photovoltaic Bracket for Exhibitions". Technical Field

[0002] This application relates to the field of photovoltaic equipment technology, and in particular to a flexible tracking photovoltaic bracket for use in exhibitions. Background Technology

[0003] Flexible photovoltaic (PV) support structures serve as the load-bearing structures for PV panels. They enable the panels to rotate and adjust their angle according to the sun's movement, maximizing the surface area for sunlight exposure and improving power generation efficiency. However, current flexible PV support structures are complex and have large spans. Simply scaling down the actual product proportionally not only occupies a significant amount of space but also makes it difficult to effectively showcase the functional structures. Conversely, exhibiting only one span makes it difficult to fully demonstrate flexible tracking structures, cable-stayed structures, and other features. This results in an inability to effectively demonstrate the structural design of the PV support structure, negatively impacting product presentation and the purchasing intentions of target buyers.

[0004] Therefore, how to provide a flexible tracking photovoltaic bracket that meets the functional requirements is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0046] The core of this application lies in disclosing a flexible tracking photovoltaic bracket that meets functional requirements, which is a technical problem that urgently needs to be solved by those skilled in the art.

[0047] To enable those skilled in the art to better understand the present application, embodiments of the present application will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model described in the claims. Additionally, the complete content of the structures represented in the following embodiments is not limited to those necessary for the solution of the utility model described in the claims.

[0048] like Figure 1 and Figure 2 As shown, this disclosure provides a flexible tracking photovoltaic support for exhibitions, which mainly includes a base 10, a column assembly 20, a main cable 310, and a stay cable 320. The base 10 is constructed from multiple beams. This beam structure offers significant advantages. Firstly, the length and number of beams can be flexibly selected based on the specific dimensions and shape of the exhibition venue, allowing the base 10 to adapt to various site conditions. Whether in a large indoor exhibition hall or an irregular outdoor exhibition area, a stable foundation for the base 10 can be built by adjusting the beam splicing method. Secondly, the spliced ​​base 10 facilitates transportation and installation. During the exhibition preparation phase, the beams can be transported to the site separately and then quickly spliced, greatly saving transportation costs and on-site setup time, and improving the overall deployment efficiency of the photovoltaic bracket. Furthermore, during the exhibition, the base 10 can be moved to facilitate the movement of the entire flexible tracking photovoltaic bracket. For flexible tracking photovoltaic brackets that require relocation after assembly, multiple lockable casters can be installed on the ground-facing side of the base 10. When the flexible tracking photovoltaic bracket needs to be moved, the casters can be unlocked, and the base 10, as well as the entire flexible tracking photovoltaic bracket, can be moved by applying a pushing or pulling force.

[0049] Based on the stable and adjustable load-bearing structure provided by the base 10, such as Figure 1 and Figure 3 As shown, two sets of column assemblies 20 are spaced apart on the base 10. The column assemblies 20 support the main cable 310, thereby enabling the installation of the photovoltaic module 60. The spaced-apart column assemblies 20 provide reasonable and necessary space for the subsequent installation and tracking adjustment of the photovoltaic module 60. It should be noted that the distance between the two sets of column assemblies 20 can be selected according to the size of the photovoltaic module 60 and the expected tracking adjustment range. For exhibitions with large spans, other column assemblies 20 can be set between the two sets of column assemblies 20 to reduce the load between adjacent column assemblies 20 and better withstand the weight of the photovoltaic module 60 and the impact of external environmental factors such as wind and personnel activities at the exhibition site.

[0050] Specifically, in the flexible tracking photovoltaic support provided in this disclosure, the column assembly 20 includes a support column 210 and a rotating part 220. The bottom of the support column 210 is fixedly connected to the base 10, while the rotating part 220 is disposed on the support column 210. It should be noted that the rotating part 220 can be disposed at any position on the support column 210. In some embodiments of this disclosure, the rotating part 220 is disposed at the top of the support column 210 to maximize the utilization of the column size of the support column 210. The support column 210 is made of high-strength steel, which can ensure that it can withstand the weight of the photovoltaic module 60 while also resisting the effects of external forces such as strong winds that may occur at the exhibition site. At the same time, the cross-sectional shape of the support column 210 can be designed as rectangular, circular, or other suitable shapes to meet different structural strength and installation space requirements.

[0051] The rotating part 220 is a key component in the column assembly 20 that enables the photovoltaic module 60 to track. It is fixedly mounted on the support column 210, and at least a portion of it can rotate relative to the support column 210. In some embodiments of this disclosure, a portion of the rotating part 220 is fixed to maintain a stable connection with the support column 210, while another portion rotates relative to the fixed portion. This structure fulfills the rotation requirements of the rotating part 220. Through the rotation of the rotating part 220, the photovoltaic module 60 adjusts its angle according to the changing position of the sun, thus always facing the sun and improving the power generation efficiency of the photovoltaic module 60. It should be noted that the rotation range of the rotating part 220 can be optimized according to the specific time and location of the exhibition to ensure that the photovoltaic module 60 can rotate throughout the entire exhibition to achieve the best lighting angle for display.

[0052] Furthermore, the rotation adjustment of the photovoltaic module 60 by the rotating part 220 is achieved by adjusting the crossbeam 230. Specifically, the area on the rotating part 220 that can rotate based on the support column 210 is fixedly provided with the adjusting crossbeam 230 to drive the adjusting crossbeam 230 to rotate. The two ends of the main cable 310 are respectively fixed to the two adjusting crossbeams 230 on the two sets of column assemblies 20. It should be noted that the design of the adjusting crossbeam 230 takes into account the tension of the main cable 310 and the weight distribution of the photovoltaic module 60 to ensure that the main cable 310 can remain stable and will not loosen or deform when the photovoltaic module 60 is tracking and rotating. At the same time, the area of ​​the adjusting crossbeam 230 for fixing the main cable 310 can also be provided with a bolt adjustment mechanism to fine-tune the tension of the main cable 310, thereby further optimizing the installation and tracking effect of the photovoltaic module 60.

[0053] At least two main cables 310 are provided, and the two main cables 310 are arranged in parallel to facilitate the smooth installation and fixation of the photovoltaic module 60. In some embodiments of this disclosure, a fixing node 2320 is welded and fixed to the adjusting beam 230. It should be noted that in the embodiments of this disclosure, the fixing node 2320 is an integrated cable holder, which maintains a stable connection structure with the adjusting beam 230 and provides an installation structure for the main cables 310. A first reinforcing plate 2330 can be provided on the back of the fixing node 2320 to achieve a stable connection effect on the adjusting beam 230. The main cables 310 pass through the fixing node 2320 and are fixed using special anchors, cable clamps, or bolts to maintain the integrated structure of the adjusting beam 230 and improve the structural stability of the adjusting beam 230. Based on this, by adjusting the rotating part 220 to drive the adjusting beam 230 to rotate, the adjusting beam 230 can drive at least two main cables 310 to rotate, thereby realizing the rotation adjustment of the photovoltaic module 60, enabling the photovoltaic module 60 to track sunlight. The stay cable 320 is used to enhance the structural stability of the column assembly 20. Specifically, the first end of the stay cable 320 is fixed to the base 10, and the second end is fixed to the area of ​​the column assembly 20 near the rotating part 220, so as to effectively improve the resistance of the column assembly 20 to lateral forces and ensure the structural stability of the flexible tracking photovoltaic bracket at the exhibition site.

[0054] It should be noted that in some embodiments of this disclosure, the stay cables 320 and the main cables 310 are arranged in a one-to-one correspondence. That is, for a flexible tracking photovoltaic support with two main cables 310, two stay cables 320 are arranged simultaneously. On the basis of the two main cables 310 being symmetrically arranged about a set of column components 20, the two stay cables 320 are also symmetrically arranged about the same set of column components 20, so that the two sets of stay cables 320 can more evenly tighten the rotating part 220 where the main cables 310 are located, thereby improving the stability of the main cables 310 during the rotation adjustment process.

[0055] During the exhibition, the structural design of the main cable 310 and the stay cable 320 enabled the photovoltaic support to stably bear and support the photovoltaic module 60, while maintaining structural stability when the photovoltaic module 60 rotates in tracking mode. The main cable 310 is fixed and maintains tension connection through the adjustable crossbeam 230, ensuring the stability and safety of the photovoltaic module 60 during the load-bearing process. The stay cable 320, through the diagonal connection between the base 10 and the column assembly 20, enhances the lateral force resistance of the entire photovoltaic support and improves the reliability of the photovoltaic support under the complex environmental conditions of the exhibition site. At the same time, all the above structures are based on the easy-to-assemble and flexibly adjustable base 10, thus not only solving the load-bearing and stability problems of the photovoltaic module 60 in the exhibition scene, but also providing an efficient and reliable flexible tracking photovoltaic support solution for the exhibition site, demonstrating the innovative application and practical value of photovoltaic technology in the exhibition scene.

[0056] To further enhance the stability of the flexible tracking photovoltaic bracket provided in this disclosure, and to achieve a more comprehensive structural demonstration at exhibitions, in some embodiments of this disclosure, such as... Figure 1 and Figure 4 As shown, the flexible tracking photovoltaic support system used at the exhibition also includes a wind-resistant frame 40 to enhance the stability of the entire support structure in the complex environment of the exhibition site. Specifically, the wind-resistant frame 40 is located at the midpoint of two adjacent sets of column components 20 and is connected to the main cable 310. Since the main cable 310 bears the weight of the photovoltaic module 60 and is subjected to certain dynamic forces during tracking, setting the wind-resistant frame 40 at the midpoint of the column component 20 can effectively balance the forces on both sides of the main cable 310. It should also be noted that the structure of the wind-resistant frame 40 meets its stress characteristics under strong wind conditions. Typically, the wind-resistant frame 40 can adopt an inverted triangle or frame structure to have high rigidity and stability, effectively resisting the lateral thrust generated by the wind on the photovoltaic support system.

[0057] Furthermore, the wind-resistant frame 40 and the single main cable 310 provided in this disclosure have at least two connection points. For the two main cables 310, the connection of the wind-resistant frame 40 can reduce the risk of their radial rotation under the influence of wind. For the single main cable 310, the wind-resistant frame 40 and its at least two connection points can reduce the risk of the single main cable 310's axial expansion and contraction rotation, reduce the stress concentration phenomenon of the main cable 310 under strong wind conditions, and thus reduce the risk of deformation or damage to the main cable 310 due to excessive stress. In addition, through the connection between the single main cable 310 and the wind-resistant frame 40, and the cooperation between the adjacent main cables 310 and the wind-resistant frame 40, the main cable 310 achieves a stable support effect for the photovoltaic module 60, thus achieving a good effect demonstration.

[0058] Furthermore, based on the above embodiments, the flexible tracking photovoltaic support also includes at least two stabilizing cables 410. First, the two ends of the stabilizing cable 410 are fixed to two adjusting beams 230 respectively, so that the starting point and ending point of the stabilizing cable 410 are the same as the main cable 310, thereby optimizing the stability of the effective working area of ​​the main cable 310. Second, the stabilizing cable 410 is fixedly connected to the wind-resistant frame 40, so that the main cable 310 and the wind-resistant cable on one side can form a spindle structure with small cross-sections at both ends and large cross-sections in the middle, thus forming a support structure in the working area of ​​the main cable 310.

[0059] The stabilizing cable 410 is located at the bottom of the main cable 310. Its connection to the adjusting beam 230 can be the same as that of the main cable 310, i.e., a fixing node 2320 is also provided on the adjusting beam 230 to fix the stabilizing cable 410. The stabilizing cable 410 located at the bottom of the main cable 310 can prevent the stabilizing cable 410 from affecting the structure of the main cable 310's load-bearing area, thus maintaining the installation effect of the photovoltaic module 60. In some embodiments of this disclosure, for a single set of main cables 310 and stabilizing cables 410, i.e., a pair of main cables 310 and stabilizing cables 410 located on the same side of the flexible tracking photovoltaic support, the main cable 310 has two connection points with the wind-resistant frame 40 along its length, while the stabilizing cable 410 has one connection point with the wind-resistant frame 40 along its length. These three connection points form an isosceles triangle structure with the main cable 310 as its base. Furthermore, the wind-resistant frame 40 can also be equipped with profile structures on the two sides of this isosceles triangle structure to improve wind resistance.

[0060] It should be further explained that, in the embodiments provided in this disclosure, not only is the tracking display requirement of the flexible tracking photovoltaic bracket realized through the structural display of the column head node 240, but also the display of a complete span of the flexible tracking photovoltaic bracket is realized through the setting of two column components 20 and the cooperation structure of the stay cables 320, without the need to scale down the actual result proportionally or to purchase additional parts for display, thus reducing the display cost; and within the span of the displayed structure, wind-resistant structure, main cable structure and end stay structure are included, realizing the complete effect display of the flexible tracking photovoltaic bracket. At the same time, the displayed structure mostly adopts the structure of anchoring and bolt connection. Considering that the external environment of the exhibition is not as harsh as the actual operating environment, a wind-resistant frame is set between the spans of the flexible tracking photovoltaic bracket used for display, and there is no need to set vertical stay cables and anti-arch cables, thus improving the ease of assembly.

[0061] Furthermore, in the flexible tracking photovoltaic mounting system provided in this disclosure, such as Figure 1 and Figure 5As shown, in the column assembly 20, the top of the support column 210 is provided with a column head node 240, which serves as a connection structure connecting the support column 210 and the rotating part 220. The column head node 240 can be assembled separately with the support column 210, while the rotating part 220 is a reducer fixedly mounted on the column head node 240. Simultaneously, the adjusting beam 230 is fixedly mounted on the rotating area of ​​the reducer. The rotation of the reducer drives the adjusting beam 230 to rotate, thereby driving the main cable 310 and the photovoltaic module 60 to adjust their angles, thus achieving flexible tracking functionality. It should be noted that in some embodiments of this disclosure, the reducer is a horizontal reducer, and it is fixed by at least four bolts distributed at the four vertices of the rectangle through the adjusting beam 230 to ensure its integral structure with the adjusting beam 230, thereby maintaining its stability during the rotation drive process of the adjusting beam 230.

[0062] It needs to be further explained that, such as Figure 6 As shown, a third reinforcing plate 2440 is also provided between the reducer and the adjusting beam 230 to improve the connection effect between the reducer and the adjusting beam 230. The third reinforcing plate 2440 has two edges that respectively contact the reducer and the adjusting beam 230 so that it can be welded and fixed to the reducer and the adjusting beam 230 respectively. In this embodiment, multiple third reinforcing plates 2440 can be provided at intervals along the length of the adjusting beam 230. Similarly, the third reinforcing plates 2440 can also be provided on one or both sides of the upper and lower sides of the adjusting beam 230. Furthermore, for the assembly of the third reinforcing plate 2440, it can be pre-welded to the reducer, and the third reinforcing plate 2440 and the adjusting beam 230 can be welded together after the reducer and the adjusting beam 230 are connected. Similarly, the third reinforcing plate 2440 can also be pre-welded to the adjusting beam 230, and the third reinforcing plate 2440 and the reducer can be welded together after the adjusting beam 230 and the reducer are assembled. Alternatively, the third reinforcing plate 2440 can also be welded to the reducer and the adjusting beam 230 after the reducer and the adjusting beam 230 are assembled, according to the strength requirements.

[0063] In order to further optimize the above technical solutions, such as Figure 5 and Figure 6As shown, the column head node 240 specifically includes a connecting plate 2410 and two connecting lugs 2420. The connecting plate 2410 is fixed to the support column 210 by welding or bolting, thereby ensuring the integrity and stability between the column head node 240 and the support column 210. It should be noted that the support column 210 is mostly a concrete column, while the connecting plate 2410 can be fixed at the top of the support column 210 by pre-embedding or bolting. At the same time, it provides a stable mounting plane for other structures on the column head node 240, so that other structures on the column head node 240 can be fixed by convenient welding.

[0064] The connecting lug 2420 provides the necessary support and connection points for the installation of the stay cable 320. Specifically, the connecting lug 2420 is a one-piece bent plate, which allows the connecting lug 2420 to meet bending requirements while avoiding the impact of welds on its structural strength, thus giving the connecting lug 2420 high structural strength and stability. Simultaneously, to facilitate the fixing of the stay cable 320, the connecting lug 2420 has connecting holes 24210 in its bent area. The bent areas of the two connecting lugs 2420 are arranged to face outwards, meaning that after the two connecting lugs 2420 are fixed, their bent areas are oriented away from the center of the column head node 240. Correspondingly, as... Figure 7 and Figure 8 As shown, the second end of the stay cable 320 is provided with a stay cylinder 3210. The stay cylinder 3210 has an installation groove for the bending area of ​​the connecting ear plate 2420 to be embedded in. At the same time, the stay cylinder 3210 has a through hole and is fixed to the connecting hole 24210 of the connecting ear plate 2420 by a connecting pin 3220. The above connection structure not only ensures a firm connection between the stay cable 320 and the column head node 240, but also can directly transmit the tension force of the stay cable 320 to the column head node 240 through the connecting ear plate 2420, thereby achieving an auxiliary tensioning effect on the main cable 310.

[0065] Based on the above embodiments, the connecting ear plate 2420 is a bent plate with an integral structure and a bending angle designed to be 135°-170°. This ensures that the acute angle between the two areas of the connecting ear plate 2420 is maintained between 20°-90°, thus maintaining the stability of the bent structure of the connecting ear plate 2420 while ensuring that the tension transmission effect of the stay cable 320 meets the tensioning requirements. In a specific embodiment of this disclosure, the bending angle of the connecting ear plate 2420 is designed to be 165°. After the two connecting ear plates 2420 are fixed on the connecting plate 2410, they can form a 30° unfolding angle, thereby making the two stay cables 320 form a 30° angle to provide sufficient support and connection strength, while avoiding the tensioning performance of the stay cable 320 due to excessively large or small bending angles.

[0066] Furthermore, in some embodiments of this disclosure, such as Figure 6 As shown, the column head node 240 specifically includes a column head end plate 2430 for providing a bearing plane. The column head end plate 2430 is set perpendicular to the connecting plate 2410 and is embedded between two connecting lugs 2420, and is simultaneously welded and fixed to the two connecting lugs 2420, so that the column head end plate 2430 and the two connecting lugs 2420 form a stable I-shaped structure, improving the structural stability of the column head node 240. At the same time, the column head end plate 2430 also serves to provide a stable mounting platform for the reducer. The reducer is set on the column head end plate 2430, and through the bearing plane of the column head end plate 2430, the reducer can work stably for a long time during the exhibition.

[0067] Meanwhile, the setting of the column head end plate 2430 can also realize the effective transmission of the force of the stay cable 320. That is, the stay cable 320 can achieve stable tension of the reducer through the column head end plate 2430, thereby improving the running stability of the main cable 310 during the process of the reducer adjusting the rotation of the main cable 310.

[0068] In addition, it should be noted that, as Figure 6 As shown, the column head node 240 provided in this embodiment of the present disclosure also includes a combination plate 2450. The combination plate 2450 is arranged parallel to the connecting plate 2410, and the connecting ear plate 2420 and the column head end plate 2430 are both fixed on the combination plate 2450. The number of combination plates 2450 can be increased according to the strength requirements of the column head node 240. It should be noted that a combination plate 2450 is abutted against the side of the column head end plate 2430 facing the connecting plate 2410 and welded to the combination plate 2450, so that the rotational force of the reducer carried by the column head end plate 2430 can be directly transmitted to the combination plate 2450 through the column head end plate 2430, and then directly transmitted to the connecting ear plates 2420 on both sides through the combination plate 2450, and carried by the cable 320 to ensure the stability of the column head node 240 during rotation.

[0069] It should be noted that in some embodiments of this disclosure, such as Figure 7 and Figure 13As shown, in the connection structure of the column head node 240, the bottom of the connecting ear plate 2420 is fixedly connected to the connecting plate 2410. Based on the area of ​​the connecting plate 2410 extending outward for the fixed connection of the stay cable 320, it has an arc-shaped upward structure. This not only provides sufficient extension space for the fixation of the stay cable 320 to avoid interference between the stay cable 320 and the connecting plate 2410 and other structures, thus avoiding wear, but also the arc-shaped upward structure can reduce the risk of stress concentration on the connecting ear plate 2420 when the stay cable 320 generates a diagonal tension force. Meanwhile, for the mating area between the connecting lug plate 2420 and the column head end plate 2430, the column head end plate 2430 is provided with an avoidance notch 2460 to allow for a certain gap between the connecting lug plate 2420 and the column head end plate 2430 in the vertical mating area. This provides for a certain assembly tolerance and avoids the risk of weld joint failure and mutual extrusion forces that would result from close contact between the connecting lug plate 2420 and the column head end plate 2430. Furthermore, the two sharp corner areas where the column head end plate 2430 connects to the composite plate 2450 are chamfered to form two connection notches 2470. The connection notches 2470 can avoid the risk of stress concentration between the column head end plate 2430 and the composite plate 2450. At the same time, this is the intersection area of ​​three welds, and the notch setting can also provide sufficient space for the weld intersection area, thus avoiding welding failure caused by abnormal weld stacking.

[0070] Furthermore, in some embodiments of this disclosure, a plurality of column base plates 2110 are evenly arranged circumferentially at the bottom of the support column 210 to improve the connection effect between the bottom of the support column 210 and the base 10 and reduce the risk of swaying of the support column 210; while the column head end plate 2430 and the column base plates 2110 are both arranged perpendicular to the base 10, so that the support column 210 plays a vertical support role in the entire photovoltaic bracket, ensuring the structural stability of the entire bracket.

[0071] In addition, it should be noted that, as Figure 11As shown, the support column 210 provided in this embodiment can also adopt a split structure, that is, the support column 210 is a multi-section support part 2120, which is assembled on-site to reduce the storage and transportation costs of the support column 210. Specifically, a support plate 2130 is provided in the docking area of ​​adjacent support parts 2120. The outer diameter of the support plate 2130 is larger than that of the support part 2120, so that the two support plates 2130 have a larger docking area and improve the structural stability of the support column 210 after assembly. At the same time, the two support plates 2130 are assembled and locked together by multiple bolts evenly arranged in the circumferential direction. A second reinforcing plate 2140 is provided between each support part 2120 and the support plate 2130. The structure of the second reinforcing plate 2140 is similar to that of the column base plate 2110, both being triangular structures, to improve the connection effect between the support part 2120 and the support plate 2130, ensuring the structural stability of the assembled support column 210. This allows the photovoltaic bracket to demonstrate efficient, flexible and reliable performance characteristics in the exhibition scene.

[0072] It should be noted that in some embodiments of this disclosure, two adjacent support parts 2120 are fixed with six bolts of not less than M10×45; while the support column 210 is fixed to the base 10 with eight bolts of M16×60, and the bolts are fitted with two flat washers and one elastic washer on their outer periphery when they are fixed.

[0073] In the flexible tracking photovoltaic support provided in this disclosure, the base 10 is the load-bearing foundation and the basis for the flexible adjustment and display of the flexible tracking photovoltaic support. To ensure the reliability and flexibility of the base 10, in some embodiments of this disclosure, the base 10 is composed of at least two parallel load-bearing beams 110, and the distance between any two adjacent load-bearing beams 110 is equal. The load-bearing beams 110 are the main load-bearing structures of the base 10. The parallel arrangement of the load-bearing beams 110 allows the base 10 to evenly distribute the weight of the photovoltaic module 60 and the support itself, avoiding excessive local stress that could lead to structural deformation or damage. At least three parallel load-bearing beams 110 enable the column assembly 20 to be placed on the middle load-bearing beam 110 to improve its stability and provide sufficient space for the installation of the stay cables 320.

[0074] It should be noted that the number of load-bearing beams 110 can be adjusted according to the exhibition space and the display effect requirements of the flexible tracking photovoltaic bracket, so as to meet the needs of different exhibition scenarios while ensuring the scale and expected load-bearing capacity of the photovoltaic bracket.

[0075] To ensure the stability and integrity of the base 10, the supporting beams 110 are vertically connected by multiple connecting beams 120. Multiple sets of connecting beams 120 are spaced apart along the length of the supporting beams 110, which not only improves the torsional and lateral force resistance of the base 10 but also provides necessary connection points for the installation of the column assembly 20 and the stay cables 320. It should be noted that, considering the adjustment requirements of the base 10, the connecting beams 120 are typically fixed to the supporting beams 110 using high-strength bolts.

[0076] The aforementioned structure can be assembled on-site at the exhibition to meet the structural requirements of the base 10. Based on the base 10's structure with three or more load-bearing beams 110, the load-bearing beams 110 on both sides will form a T-shaped connection with the connecting beams 120 due to the vertical arrangement of the connecting beams 120. The load-bearing beams 110 in the middle area will form a cross-shaped intersection connection due to the connecting beams 120 on both sides. Furthermore, the bottom of the column assembly 20 is located at the cross-shaped intersection area formed by the load-bearing beams 110 and the connecting beams 120, allowing the column assembly 20 to directly utilize the structural strength of the load-bearing beams 110 and the connecting beams 120 of the base 10, thereby improving the stability of the column assembly 20. The cross-shaped intersection area is one of the strongest parts of the base 10 structure; placing the bottom of the column assembly 20 in this area ensures that the column assembly 20 remains stable when bearing the weight of the photovoltaic module 60 and external forces, reducing the possibility of swaying and deformation.

[0077] Meanwhile, such as Figure 7 and Figure 10 As shown, the intersection of the first end of the stay cable 320 and the base 10 is located in the cross-shaped intersection area or T-shaped intersection area of ​​the supporting beam 110 and the connecting beam 120. If the base 10 is provided with only three supporting beams 110, then only the supporting beam 110 in the middle area can form a cross-shaped intersection area with the surrounding connecting beams 120. At this time, the bottom of the column assembly 20 is located in the cross-shaped intersection area formed by the supporting beam 110 and the connecting beam 120, and the first end of the stay cable 320 can only be fixed to the base 10 at the two ends. The side support beam 110 is located at the T-shaped intersection area formed by the support beam 110 and the connecting beam 120. If the base 10 is provided with three or more support beams 110, then based on the bottom of the column assembly 20 located at the cross-shaped intersection area formed by the support beam 110 and the connecting beam 120, the intersection point of the first end of the stay cable 320 with the base 10 can be selectively located at the cross-shaped intersection area or the T-shaped intersection area of ​​the support beam 110 and the connecting beam 120, so that the stay cable 320 has a better connection effect.

[0078] It should be noted that, regarding the fixing of the first end of the stay cable 320 to the base 10, whether it is located at the cross-shaped intersection area of ​​the bearing beam 110 and the connecting beam 120 or the T-shaped intersection area, the external force that the stay cable 320 can receive can be effectively transferred to the bearing beam 110 and the connecting beam 120 of the base 10, thereby enhancing the wind resistance of the photovoltaic support and effectively resisting the lateral thrust generated by the external force on the photovoltaic support by dispersing the point of application of the external force, further optimizing the structural stability of the entire support.

[0079] Furthermore, to enhance the stability of the base 10 structure, in some embodiments of this disclosure, considering that the force exerted by the stay cable 320 on the base 10 is oblique, a counterweight 130 is also provided on the base 10 near the first end of the stay cable 320. The counterweight 130 is made of multiple hot-dip galvanized steel plates stacked together to directly counteract the overturning moment generated by the stay cable 320 under stress. The counterweight 130 is arranged parallel to the connecting beam 120 and is snapped between two adjacent load-bearing beams 110. The snap-fit ​​structure not only ensures the stable installation of the counterweight 130, but also allows the counterweight 130 to form an integral structure with the load-bearing beams 110 and connecting beams 120 of the base 10, further enhancing the overturning resistance and stability of the base 10. At the exhibition, this structural design of the counterweight 130 can significantly enhance the overturning resistance of the photovoltaic support, and it can also be adapted to the needs of the exhibition.

[0080] It should be noted that, in one embodiment of this disclosure, the single counterweight 130 is made of eight hot-dip galvanized steel plates, each 700mm long, 260mm wide, and 20mm thick, stacked together, and is provided at both ends of the bearing beam 110 along its length. Four sets of counterweights 130 are provided at each end of the bearing beam 110.

[0081] To further improve the ease of exhibiting flexible tracking photovoltaic brackets, such as Figure 1 and Figure 12As shown, in some embodiments of this disclosure, the load-bearing beam 110 is segmented and spliced ​​together. Specifically, a single load-bearing beam 110 is segmented, including two load-bearing parts 1110, and the two load-bearing parts 1110 are fixed by splicing nodes 1120. The segmented design allows the load-bearing beam 110 to be flexibly adjusted according to the specific dimensions and space conditions of the exhibition site, facilitating the rapid construction of the base 10 in different locations. At the same time, the segmented splicing method also facilitates transportation, especially when the exhibition site is relatively dispersed or space is limited. The load-bearing beam 110 can be transported to the site in segments and then quickly spliced, greatly improving installation efficiency. The splicing node 1120 includes at least three sets of connecting bolts to fix the two bearing parts 1110 from the upper surface, lower surface and middle wall of the bearing part 1110 after the plates are fastened. The multi-point connection method ensures the firmness and reliability of the splicing and can effectively transmit various forces subjected to the bearing beam 110 during use. The number of connecting bolts in each set is not less than 8, which further enhances the strength of the splicing node 1120 and ensures that the bearing beam 110 can withstand the weight of the photovoltaic module 60 and external forces during the exhibition.

[0082] In a specific embodiment of this disclosure, the load-bearing beam 110 is an I-beam structure with a cross-sectional height and width of 200mm. The thickness of the two side flanges is 12mm, and the thickness of the web between the two flanges is 8mm. The splicing node 1120, used to connect adjacent load-bearing parts 1110, is secured with 24 bolts of at least M16×60. Similarly, the connecting beam 120, with the same specifications as the load-bearing beam 110, also has a cross-sectional height and width of 200mm, a side flange thickness of 12mm, and a web thickness of 8mm. Each connecting beam 120 is perpendicular to the load-bearing beam 110, and both ends of each connecting beam 120 are secured with bolts of at least M16×60, with at least two bolts at each end. It should be noted that the bolts are fitted with two flat washers and one elastic washer on their outer circumference during fixing.

[0083] Furthermore, the connection structure of the stay cable 320 provided in this embodiment is an important component in ensuring the overall stability of the photovoltaic support, especially under complex environmental conditions that may occur at exhibition sites. Specifically, the first end of the stay cable 320 includes a connecting seat 3230 and a U-bolt 3240. The connecting seat 3230 is the component that connects the stay cable 320 to the base 10, and its main function is to effectively transfer the tension of the stay cable 320 to the base 10. The connecting seat 3230 can be fixed to the base 10 by welding or bolting to ensure its stability when bearing the tension of the stay cable 320. Bolting is preferred for easy assembly and disassembly. The end of the stay cable 320 is inserted into the connecting seat 3230 and fixed. This insertion connection method ensures a tight connection between the stay cable 320 and the connecting seat 3230, preventing loosening due to external forces. The U-bolt 3240 is used to fix the cable body of the stay cable 320 and the connecting seat 3230. Specifically, the U-bolt 3240 is tightened with a nut, and the tightening force of the bolt can be adjusted according to actual needs to ensure that the stay cable 320 maintains appropriate tension at all times during the exhibition. The bottom of the U-bolt 3240 is sleeved on the connecting seat 3230, and the other end of the U-bolt 3240 is fixed to the non-end area of ​​the cable body of the stay cable 320 by a locking block to ensure a firm connection between the stay cable 320 and the connecting seat 3230.

[0084] Furthermore, to achieve a comprehensive demonstration of the flexible tracking photovoltaic (PV) support system, in some embodiments of this disclosure, the flexible tracking PV support system also includes a maintenance support pole 50 for installing and supporting maintenance equipment. Specifically, the maintenance support pole 50 is fixedly mounted on the base 10, allowing the maintenance support pole 50 to utilize the structural strength of the base 10 to ensure its stability during the exhibition. Simultaneously, the height and position of the maintenance support pole 50 can be optimized according to the layout of the PV modules 60 and maintenance requirements, ensuring convenient installation and operation of the maintenance equipment. The bottom of the maintenance support pole 50 can be bolted to allow for adjustment of its installation position on the base 10 as needed. In addition, a support rod or support platform is fixedly mounted on the maintenance support pole 50 to provide a stable installation platform for the maintenance equipment. The relevant maintenance equipment may include monitoring cameras, sensors, controllers, etc., for real-time monitoring of the operating status and environmental parameters of the PV modules 60. This structure not only improves the operational stability of the PV system but also provides an efficient and reliable PV support system design solution for the exhibition site, achieving a more comprehensive demonstration of the flexible tracking PV support system provided in this disclosure.

[0085] Furthermore, such as Figure 1 and Figure 9As shown in the embodiments of this disclosure, the flexible tracking photovoltaic support also includes a tilt sensor 2310 disposed on the adjusting beam 230, so that the tilt sensor 2310 can directly monitor the angle change of the adjusting beam 230. It should be noted that the adjusting beam 230 is the foundation of the photovoltaic support for supporting the main cable 310 and other structures, and it is also the foundation for realizing the angle adjustment of the photovoltaic module 60. By installing the tilt sensor 2310 on the adjusting beam 230, the actual angle of the photovoltaic module 60 can be monitored in real time, and the data can be fed back to the control system. The control system can automatically adjust the rotation angle of the reducer based on the feedback data of the tilt sensor 2310, thereby realizing the flexible tracking function of the photovoltaic module 60, so that the photovoltaic support can always maintain the best operating state during the exhibition, and realize the full operation state display of the flexible tracking photovoltaic support at the exhibition.
