Description

A flexible photovoltaic bracket and photovoltaic system

[0001] This application claims priority to Chinese Patent Application No. 2024114564291, filed on October 18, 2024, entitled "A Flexible Photovoltaic Support and Photovoltaic System", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of photovoltaic technology, and in particular to a flexible photovoltaic bracket and a photovoltaic system. Background Technology

[0003] In recent years, the photovoltaic industry has rapidly emerged alongside the rapid development of the renewable energy sector. Flexible photovoltaic (PV) supports, due to their ability to adapt to complex terrain, have demonstrated significant advantages in PV power plant construction. Flexible PV supports utilize steel strands as the main load-bearing cables, which are fixed by end supports composed of steel beams and side anchors. Because the load-bearing cables have a relatively long span (10m-60m), multiple supporting steel frame structures are required in the middle to form a central support system for supporting and fixing the load-bearing cables. The end supports also connect the load-bearing cables and stay cables, and the load-bearing cables are connected to the photovoltaic panels via connectors to form a unified whole.

[0004] In one type of flexible photovoltaic support system, the top of the column of the end support is fixed to the column head by welding or bolting. Two upright plates are then fixed to the column head by welding. The upper part of each upright plate has a circular hole connected to a pin. The middle and both ends of the pin are connected to the main cable and the diagonal tension member, respectively. The manufacturing process of this flexible photovoltaic support system involves steel plate cutting, bolting, and steel plate welding assembly, making it relatively complex and involving a large number of steel plate parts. Furthermore, the connection between the column head and the top of the column by welding or bolting presents challenges in controlling welding quality and incurring problems due to the cumbersome bolting process and numerous spare parts.

[0005] Therefore, how to reduce the production cost of flexible photovoltaic brackets and improve their quality is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0056] The core of this application is to disclose a flexible photovoltaic bracket to reduce production costs and improve quality.

[0057] Another objective of this application is to disclose a photovoltaic system including the aforementioned flexible photovoltaic bracket.

[0058] 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.

[0059] Referring to Figures 1-16, the flexible photovoltaic support disclosed in this application includes a connecting assembly and multiple photovoltaic support units arranged in parallel and at intervals. The connecting assembly connects two adjacent photovoltaic support units, and each photovoltaic support unit includes a cable assembly, a support assembly, and a wind-resistant assembly 300. The cable assembly includes a main cable 100 and a tie rod 110, and the photovoltaic panel 400 is mounted on the main cable 100. The support assembly includes two sets of end supports 200 and multiple sets of middle supports 210. Each set of middle supports 210 is spaced between two sets of end supports 200, and the middle part of the main cable 100 is connected to each set of middle supports 210. The two ends of the main cable 100 are respectively connected to the two sets of end supports 200. The first end of the tie rod 110 is connected to the end support 200, and the second end is connected to the ground. The tie rod 110 and the main cable 100 are respectively arranged on both sides of the end support 200 to avoid uneven stress and tilting of the end support 200.

[0060] The end support 200 includes an end column 201, a main cable anchor 206, and a pin 202. The end column 201 is used to support the main cable 100 and keep the main cable 100 at a certain height from the ground to meet the installation requirements of the photovoltaic panel 400. A main cable mounting hole and a pin mounting hole are provided through the end column 201 at an angle. The axes of the main cable mounting hole and the pin mounting hole are usually arranged perpendicularly and are connected. A first connecting hole is provided through the main cable anchor 206, and a second connecting hole is provided through the side wall of the pin 202. The pin 202 passes through the pin mounting hole. The end of the main cable 100 passes through the first connecting hole and the second connecting hole. The main cable anchor 206 is fixedly connected to the main cable 100. The main cable anchor 206 abuts against the pin 202. The pin 202 can limit the main cable anchor 206 to the main cable mounting hole, thereby fixing the main cable 100 to the end bracket 200.

[0061] The diameter of the pin mounting hole is set with reference to the diameter of pin 202, ensuring that pin 202 can pass through the mounting hole and rotate. The cross-section of the pin mounting hole includes, but is not limited to, a circle. The main cable mounting hole can be an oblong hole, a round hole, a rectangular hole, a square hole, etc., and must meet the ±45° movement requirements of the main cable 100 and the main cable anchor 206 relative to the end column 201. The opening methods for the pin mounting hole and the main cable mounting hole include, but are not limited to, laser cutting, steel structure thermal cutting, flame cutting, cold cutting, water jet cutting, etc. Laser cutting is preferred because it ensures reliable quality control and high processing efficiency.

[0062] The wind-resistant components 300 are in multiple groups and are connected to the main cable 100. Each group of wind-resistant components 300 is arranged at intervals between the two end supports 200 to enhance the wind resistance performance of the flexible photovoltaic support.

[0063] Compared with related technologies, this application fixes the main cable 100 by opening holes in the end column 201, and the force of the main cable 100 can be directly applied to the end column 201 through the pin 202, which ensures the integrity of the structure at the column head position of the end column 201, thereby greatly improving the reliability of the structure, reducing the number of parts, simplifying the processing process, improving processing efficiency, and reducing costs.

[0064] The types of cable-stayed components 110 include, but are not limited to, stay cables, wire ropes, stay steel pipes, and stay steel bars, which can provide a certain preload. To reduce production costs, as shown in Figure 1, each cable assembly includes two main cables 100 and four cable-stayed components 110. Each photovoltaic panel 400 is laid out at intervals along the extension direction of the main cables 100 and fixed to them. The number of central support brackets 210 and wind-resistant components 300 can be set according to actual needs, and will not be listed individually here.

[0065] In a specific embodiment disclosed in this application, referring to Figure 1, the wind-resistant component 300 and the middle support 210 are arranged sequentially and alternately between the two sets of end supports 200, which enhances the stability of the entire structure of the flexible photovoltaic support provided in this embodiment, giving it a strong ability to resist strong winds and severe weather, reducing the risk of microcracks in the photovoltaic panels 400 installed on the flexible photovoltaic support, and ensuring the normal operation of the photovoltaic system.

[0066] Referring to Figures 2 and 7, the bottom of the end column 201 is fixed to the ground by the second ground pile 207, and the main cable 100 is connected to the top of the end column 201. Correspondingly, the main cable mounting hole and the pin mounting hole are both set at the top of the end column 201. Since the end column 201 is usually a hollow round tube, square tube or other metal tube, opening the hole will reduce the structural strength of the column head at the top of the end column 201. Therefore, in order to reinforce the column head of the end column 201, referring to Figure 3, the end support 200 also includes a cover plate 204. The cover plate 204 is set at the top of the end column 201 and welded to the top of the end support 200, which can effectively enhance the structural strength at the column head of the end column 201 and avoid deformation. Specifically, the shape of the cover plate 204 can match the cross-sectional shape of the end column 201.

[0067] In one embodiment, the cover plate 204 includes a top plate and two side plates, which are vertically disposed at both ends of the top plate. The side plates have clearance holes communicating with the pin mounting holes. The side plates are welded to the end posts 201 and contact the pins 202, effectively enhancing the structural strength at the pin mounting holes and preventing yielding deformation of the steel plate at the pin mounting holes under stress. Furthermore, the arrangement of the top plate effectively prevents excessive adhesion of external impurities to the location of the pins 202. Specifically, the cover plate 204 can be prepared by bending a steel plate.

[0068] Those skilled in the art will understand that although the cover plate 204 is welded to the end column 201, since the main purpose of the cover plate 204 is reinforcement and its welded part is not the main stress-bearing part of the end column 201, the quality requirements for the welding of the cover plate 204 are not high, and it will not lead to a significant increase in cost.

[0069] In some embodiments, since the pin 202 is cylindrical, to facilitate the abutment and fixation of the main cable anchor 206 to the circumferential sidewall of the pin 202, in some embodiments, referring to Figures 4 and 5, a positioning plane 2021 is provided on the sidewall of the pin 202. The second connecting hole is opened on the positioning plane 2021. After the flexible photovoltaic support is assembled, the end face of the main cable anchor 206 facing the pin 202 is attached to and abuts against the positioning plane 2021. Specifically, the positioning plane 2021 can be formed by cutting or grinding, and for ease of assembly, there can be two positioning planes 2021, symmetrically arranged at both ends of the second connecting hole. The shape of the positioning plane 2021 is not limited to rectangle and circle, as long as it can completely attach to the end face of the main cable anchor 206 facing the pin 202. In other embodiments, referring to Figures 3 and 6, the end bracket 200 further includes a retainer 205. The retainer 205 has a third connecting hole and is positioned between the main cable anchor 206 and the pin 202. The main cable 100 passes through the third connecting hole. The end of the retainer 205 facing the main cable anchor 206 has a first contact surface that fits against the end face of the main cable anchor 206, and the end of the retainer 205 facing the pin 202 has a second contact surface that fits against the circumferential sidewall of the pin 202. The first contact surface is planar, and the second contact surface is curved. After the flexible photovoltaic bracket is assembled, the retainer 205 is pressed between the main cable anchor 206 and the pin 202, with the first contact surface fitting against the end face of the main cable anchor 206 and the second contact surface fitting against the circumferential sidewall of the pin 202.

[0070] Those skilled in the art will understand that, compared to the solution of adding a card holder 205, the solution of setting a positioning plane 2021 on the circumferential sidewall of the pin 202 occupies less space, has lower cost, and the main cable anchor 206 is easier to arrange inside the end bracket 200, making it the preferred solution.

[0071] The cable tie member 110 is hinged to the end bracket 200 to facilitate fine-tuning of the angle. Referring to Figure 3, the end of the cable tie member 110 is connected to the hinge bolt 111. A fourth connecting hole is provided on the hinge bolt 111. The end of the pin 202 passes through the fourth connecting hole and is limited by the locking pin 203. The main cable 100 and the cable tie member 110 share the same pin 202 for fixation, which effectively reduces production costs and facilitates installation.

[0072] In a specific embodiment disclosed in this application, the end bracket 200 includes two parallel and spaced-apart end columns 201 and at least one end support beam 208, with the end support beam 208 connecting the two end columns 201. The end support beam 208 allows the two end brackets 200 to be connected to form a whole, thereby improving the overall structural strength of the end bracket 200.

[0073] To further optimize the design, multiple position adjustment holes are provided on the end column 201, spaced apart along the extension direction of the end column 201. Hinge holes are provided at both ends of the end support beam 208, with hinge shafts passing through the hinge holes and position adjustment holes to allow for a hinged connection between the end column 201 and the end support beam 208. The multiple position adjustment holes facilitate adjustment of the connection position of the end support beam 208, thus adapting to different installation scenarios. Alternatively, slotted holes are provided on the end column 201, arranged along its extension direction. The end support beam 208 is bolted to different positions within these slotted holes, allowing for adjustment of the installation position.

[0074] In one embodiment, referring to Figure 7, a mounting base is hinged to each end of the end support beam 208, and the mounting base is bolted to the position adjustment hole, which can also realize the adjustment of the installation position of the end support beam 208 and the end column 201.

[0075] Referring to Figures 7 and 8, to improve the overall structural strength of the flexible photovoltaic support system, the connecting assembly includes an end connecting beam 209. Both ends of the end connecting beam 209 are connected to the end columns 201 of two adjacent photovoltaic support units, respectively. The end connecting beam 209 allows the end columns 201 of adjacent photovoltaic support units to be connected to form a whole, thereby improving the overall structural strength of the flexible photovoltaic support system. The end connecting beam 209 can share the same set of position adjustment holes with the aforementioned end support beam 208 for adjusting its installation position.

[0076] In a specific embodiment disclosed in this application, referring to Figures 11-16, the wind-resistant component 300 includes a wind-resistant support 310, a first ground stake 330, and at least two connecting cables 320. The main cable 100 is connected to the wind-resistant support 310, and the first ground stake 330 is used to fix it to the ground to ensure the stability of the wind-resistant support 310. The two ends of the connecting cables 320 are respectively hinged to the wind-resistant support 310 and the first ground stake 330. Different connecting cables 320 are connected to different positions on the wind-resistant support 310, and the different connecting cables 320 have different lengths, so that the wind-resistant support 310 can form an installation tilt angle adapted to the installation of the photovoltaic panel 400. For example, Figures 11, 12, 14, and 16 show a scheme in which the number of connecting cables 320 is two, and the two connecting cables 320 are respectively connected to the two ends of the wind-resistant support 310.

[0077] The wind-resistant support 310 includes a first support 311, a second support 312, and a third support 313. The first support 311 is connected to connecting cables 320 at both ends. The second support 312 is connected to the first support 311 at both ends, with its middle section parallel to and spaced apart from the first support 311. The main cable 100 is mounted on the second support 312. The third support 313 is positioned between the middle sections of the first support 311 and the second support 312 to support them and maintain their spacing. All three supports—first support 311, second support 312, and third support 313—can be made of steel.

[0078] In one embodiment, referring to Figures 11-13, the third support 313 is arranged perpendicularly to the first support 311, and the wind-resistant support 310 is generally arc-shaped; in another embodiment, referring to Figures 14-16, both ends of the third support 313 are connected to the second support 312, and the middle position is connected to the first support 311, and the wind-resistant support 310 is generally butterfly-shaped. The latter has more triangular structures than the former, resulting in better stability, while the former uses less material and has a lower cost.

[0079] Further optimization of the scheme, in conjunction with Figures 12 and 15, the connecting component includes a wind-resistant frame connecting rod 340, and the two ends of the wind-resistant frame connecting rod 340 are respectively connected to the wind-resistant supports 310 of two adjacent photovoltaic support units.

[0080] To improve versatility, multiple bracket adjustment holes are provided on the wind-resistant frame connecting rod 340. The bracket adjustment holes are arranged at intervals along the extension direction of the wind-resistant frame connecting rod 340. Depending on the actual installation scenario, the wind-resistant bracket 310 is connected to different bracket adjustment holes on the wind-resistant frame connecting rod 340 to adjust the installation position.

[0081] In a specific embodiment disclosed in this application, the central support 210 includes a central column 211 and a central crossbeam 212. The main cable 100 is connected to the central crossbeam 212. The bottom end of the central column 211 is fixed to the ground via a third ground stake 214, and the top end is connected to the central crossbeam 212. The central column 211 and the central crossbeam 212 are arranged at an angle, but the angle is not 90°. The central column 211 is vertically arranged, and the two main cables 100 are respectively connected to both ends of the central crossbeam 212, thereby forming the required installation tilt angle for the photovoltaic panel 400.

[0082] Referring to Figures 9 and 10, the middle section of the central column 211 and the central beam 212 are hinged to facilitate angle adjustment. The central support 210 also includes a support rod 213, with both ends of the support rod 213 connected to the central column 211 and the central beam 212, respectively. The central beam 212, the central column 211, and the two support rods 213 form a triangular structure, resulting in stronger structural stability.
