Description

Technical Field

[0002] In recent years, the photovoltaic industry has rapidly grown alongside the rapid development of renewable energy. Flexible photovoltaic mounting systems, with their ability to adapt to complex terrain, offer significant advantages in the construction of photovoltaic power plants. These systems utilize steel strands as the primary load-bearing cables, secured by end brackets composed of steel beams and side anchors. Due to the long spans of the load-bearing cables (10-60 meters), multiple supporting steel frames are required to form central brackets to support and secure the cables. The end brackets also connect the load-bearing cables to the stay cables, which are then connected to the photovoltaic panels via connectors, forming a single, integrated structure.

[0003] In one prior art flexible photovoltaic bracket, a column cap is secured to the top of the end bracket's column by welding or bolting. Two vertical plates are also welded to the column cap. The upper portion of the vertical plate has a circular hole connected to a pin, and the middle and ends of the pin are connected to the main cable and the diagonal member, respectively. The manufacturing process for this flexible photovoltaic bracket involves steel plate cutting, bolting, and steel plate welding and assembly. The production process is complex and involves a large number of steel plate parts. Furthermore, the welding or bolting of the column cap to the top of the column poses challenges in controlling welding quality, a cumbersome bolting process, and a large number of spare parts.

[0053] The core of the utility model is to disclose a flexible photovoltaic bracket to reduce production costs and improve quality.

[0054] Another object of the present invention is to disclose a photovoltaic system including the flexible photovoltaic bracket.

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0056] Combine Figures 1-16The flexible photovoltaic support disclosed in the present invention includes a plurality of photovoltaic support units arranged in parallel and at intervals. 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 diagonal member 110, and the photovoltaic panel 400 is used to be set on the main cable 100. The support assembly includes two groups of end supports 200 and multiple groups of middle supports 210. Each group of middle supports 210 is arranged at intervals between the two groups of end supports 200, and the middle part of the main cable 100 is connected to each group of middle supports 210, and the two ends are respectively connected to the two groups of end supports 200. The first end of the diagonal member 110 is connected to the end support 200, and the second end is connected to the ground. The diagonal member 110 and the main cable 100 are respectively arranged on both sides of the end support 200 to prevent the end support 200 from tilting due to uneven force.

[0057] The end bracket 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. The end column 201 is provided with a vertically arranged main cable mounting hole and a pin mounting hole, and the main cable mounting hole and the pin mounting hole are connected. The main cable anchor 206 is provided with a first connecting hole, and the side wall of the pin 202 is provided with a second connecting hole. The pin 202 is inserted into the pin mounting hole. The end of the main cable 100 passes through the first and second connecting holes, and the main cable anchor 206 is fixedly connected to the main cable 100. The main cable anchor 206 abuts the pin 202. The pin 202 can be used to limit the main cable anchor 206 to the main cable mounting hole, thereby achieving the fixation of the main cable 100 to the end bracket 200.

[0058] The diameter of the pin mounting hole is set with reference to the diameter of the pin 202, and it is only necessary to ensure that the pin 202 can pass through the pin mounting hole and can 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 circular hole, a rectangular hole, a square hole, etc. The main cable mounting hole needs to meet the requirements of the main cable 100 and the main cable anchor 206 for relative end columns 201±45°. The methods for opening 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 cutting, etc. Laser cutting is preferably used for opening the hole, which has reliable quality control and high processing efficiency.

[0059] There are multiple groups of wind-resistant components 300, which are connected to the main cable 100, and each group of wind-resistant components 300 is arranged at intervals between two groups of end brackets 200 to enhance the wind-resistant performance of the flexible photovoltaic bracket.

[0060] Compared with the prior art, the present invention fixes the main cable 100 by opening a hole on 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, thereby ensuring 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.

[0061] Among them, the types of inclined members 110 include but are not limited to inclined cables, steel wire ropes, inclined steel pipes, inclined steel bars and other components that can provide a certain pre-tension. Based on the consideration of reducing production costs, combined with Figure 1 Each cable assembly includes two main cables 100 and four diagonal members 110. Photovoltaic panels 400 are spaced and fixed to the main cables 100 along their extension direction. The number of central supports 210 and wind-resistant components 300 can be adjusted based on actual needs and will not be listed here.

[0062] In a specific embodiment disclosed in the present utility model, Figure 1 The wind-resistant components 300 and the middle brackets 210 are arranged in sequence and alternately between the two groups of end brackets 200, which enhances the stability of the entire structure of the flexible photovoltaic bracket provided in this embodiment, making it have a strong ability to resist strong winds and severe weather, reducing the risk of hidden cracks in the photovoltaic panels 400 installed on the flexible photovoltaic bracket, and ensuring the normal operation of the photovoltaic system.

[0063] Combine Figure 2 and Figure 7 The bottom of the end column 201 is fixed to the ground through 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 pipe, the structural strength of the column head position at the top of the end column 201 will be reduced after the hole is opened. Therefore, in order to strengthen the column head of the end column 201, the main cable 100 is connected to the top of the end column 201. Figure 3 The end bracket 200 also includes a cover plate 204, which is arranged on the top of the end column 201 and welded to the top of the end bracket 200, which can effectively enhance the structural strength of 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.

[0064] In one embodiment, the cover plate 204 comprises a top plate and two side plates, which are arranged perpendicularly at either end of the top plate. The side plates are provided with clearance holes that communicate with the pin mounting holes. The side plates are welded to the end columns 201. Their contact with the pins 202 effectively enhances the structural strength of the pin mounting holes, preventing the steel plate at these locations from yielding and deforming under stress. Furthermore, the top plate arrangement effectively prevents excessive adhesion of external impurities to the location of the pins 202. Specifically, the cover plate 204 can be manufactured by bending steel plates.

[0065] 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 welding position is not the main stress-bearing position 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.

[0066] Furthermore, since the pin shaft 202 is cylindrical, in order to facilitate the abutment and fixation of the main cable anchor 206 with the circumferential side wall of the pin shaft 202, in some embodiments, Figure 4 and Figure 5 A positioning plane 2021 is provided on the side wall of the pin 202, and the second connection hole is opened on the positioning plane 2021. After the flexible photovoltaic bracket is assembled, the end surface 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 the convenience of assembly, there can be two positioning planes 2021, which are symmetrically arranged at both ends of the second connection hole. The shape of the positioning plane 2021 is not limited to rectangular and circular, and it only needs to be able to allow the end surface of the main cable anchor 206 facing the pin 202 to be completely attached. In other embodiments, combined with Figure 3 and Figure 6 The end bracket 200 also includes a holder 205. A third connection hole is formed through the holder 205, and the holder 205 is arranged between the main cable anchor 206 and the pin 202. The main cable 100 passes through the third connection hole. The end of the holder 205 facing the main cable anchor 206 has a first surface that is in contact with the end face of the main cable anchor 206, and the end of the holder 205 facing the pin 202 has a second surface that is in contact with the circumferential side wall of the pin 202. The first surface is a flat surface, and the second surface is a curved surface. After the flexible photovoltaic bracket is assembled, the holder 205 is pressed between the main cable anchor 206 and the pin 202, and the first surface is in contact with the end face of the main cable anchor 206, and the second surface is in contact with the circumferential side wall of the pin 202.

[0067] It will be understood by those skilled in the art that, compared with the solution of adding a retaining seat 205, the solution of setting a positioning plane 2021 on the circumferential side wall of the pin shaft 202 occupies less space and has lower cost, and the main cable anchor 206 is easier to arrange inside the end bracket 200, which is the preferred solution.

[0068] The inclined member 110 is hingedly connected to the end bracket 200 to facilitate fine adjustment of the angle. Figure 3 The end of the inclined member 110 is connected to the movable bolt 111, and a fourth connecting hole is opened on the movable bolt 111. The end of the pin shaft 202 passes through the fourth connecting hole and is limited by the locking pin 203. The main cable 100 and the inclined member 110 share the same pin shaft 202 for fixation, which effectively reduces the production cost and facilitates installation.

[0069] In a specific embodiment disclosed in the present invention, the end bracket 200 includes two end columns 201 arranged in parallel and spaced apart from each other, and at least one end support beam 208, which is connected between the two end columns 201. The provision of 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.

[0070] To further optimize the solution, multiple position adjustment holes are provided on the end column 201, and the position adjustment holes are arranged at intervals along the extension direction of the end column 201; hinge holes are provided at both ends of the end support beam 208, and the hinge shaft passes through the hinge holes and the position adjustment holes to enable the end column 201 and the end support beam 208 to be hingedly connected. The provision of multiple position adjustment holes facilitates adjustment of the connection position of the end support beam 208, thereby adapting to different installation scenarios. Alternatively, waist-shaped holes are provided on the end column 201 along the extension direction of the end column 201, and the end support beam 208 is tightened at different positions of the waist-shaped holes by bolts, thereby adjusting the installation position.

[0071] In one embodiment, combining Figure 7 The two ends of the end support beam 208 are respectively hinged with a mounting seat, and the mounting seat is connected to the position adjustment hole bolt, which can also realize the adjustment of the installation position of the end support beam 208 and the end column 201.

[0072] Combine Figure 7 and Figure 8To enhance the overall structural strength of the flexible photovoltaic support, the flexible photovoltaic support further includes an end connecting beam 209. The ends of the end connecting beam 209 are connected to the end columns 201 of two adjacent photovoltaic support units. The provision of the end connecting beam 209 allows the end columns 201 of adjacent photovoltaic support units to be connected to form a single unit, thereby enhancing the overall structural strength of the flexible photovoltaic support. The end connecting beam 209 shares the same set of position adjustment holes as the aforementioned end support beam 208 for adjustment of the mounting position.

[0073] In a specific embodiment disclosed in the present utility model, Figures 11-16 The wind-resistant assembly 300 includes a wind-resistant bracket 310, a first ground pile 330, and at least two connecting cables 320. The main cable 100 is connected to the wind-resistant bracket 310. The first ground pile 330 is used to fix on the ground to ensure the stability of the wind-resistant bracket 310. The two ends of the connecting cable 320 are respectively hinged to the wind-resistant bracket 310 and the first ground pile 330. Different connecting cables 320 are connected to different positions of the wind-resistant bracket 310, and different connecting cables 320 have different lengths, so that the wind-resistant bracket 310 can form an installation inclination angle that is compatible with the installation of the photovoltaic panel 400. For example, Figure 11 、 Figure 12 、 Figure 14 and Figure 16 , a solution is shown in which there are two connecting cables 320 , and the two connecting cables 320 are respectively connected to the two ends of the wind-resistant bracket 310 .

[0074] The wind-resistant bracket 310 includes a first bracket 311, a second bracket 312, and a third bracket 313. Both ends of the first bracket 311 are connected to the connecting cable 320. Both ends of the second bracket 312 are connected to the first bracket 311. The middle position is parallel to the first bracket 311 and spaced apart. The main cable 100 is set on the second bracket 312. The third bracket 313 is connected between the first bracket 311 and the second bracket 312 to support the first bracket 311 and the second bracket 312 and ensure the spacing between them. The first bracket 311, the second bracket 312, and the third bracket 313 can all be made of steel.

[0075] In one embodiment, combining Figure 11-13 , the third bracket 313 is arranged perpendicular to the first bracket 311, and the wind-resistant bracket 310 is arched as a whole; in another embodiment, combined with Figure 14-16 Both ends of the third bracket 313 are connected to the second bracket 312, and the middle position is connected to the first bracket 311. The wind-resistant bracket 310 is butterfly-shaped as a whole. Compared with the former, the latter has more triangular structures and better stability. The former uses less materials and has lower costs.

[0076] Further optimize the solution, combined with Figure 12 and Figure 15 The wind-resistant component 300 also includes a wind-resistant frame connecting rod 340, and both ends of the wind-resistant frame connecting rod 340 are respectively connected to the wind-resistant supports 310 of two adjacent photovoltaic support units.

[0077] In order to improve versatility, a plurality of bracket adjustment holes are opened on the wind-resistant frame connecting rod 340, and the bracket adjustment holes are arranged at intervals along the extension direction of the wind-resistant frame connecting rod 340. According to 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.

[0078] In a specific embodiment disclosed herein, the central support 210 includes a central column 211 and a central crossbeam 212. The main cables 100 are 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 that is not 90°. The central column 211 is arranged vertically, and two main cables 100 are connected to the ends of the central crossbeam 212, respectively, thereby forming the required installation angle for the photovoltaic panel 400.
