[0003] In recent years, the photovoltaic industry has risen rapidly with the rapid development of the renewable energy field. Flexible photovoltaic brackets have shown great advantages in the construction of photovoltaic power stations due to their ability to adapt to complex terrain. Flexible photovoltaic brackets use steel strands as the main load-bearing cables and are fixed by end brackets consisting of steel beams and side anchors. Since the span of the load-bearing cables is long (10m-60m), it is necessary to build multiple supporting steel frame structures in the middle to form a middle bracket to support and fix the load-bearing cables. The end brackets also play the role of connecting the load-bearing cables and the inclined cables. The load-bearing cables are connected to the photovoltaic panels through connectors to form a whole.

[0004] In a flexible photovoltaic bracket in the prior art, the top of the column of the end bracket is fixed with a column cap by welding or bolting, and two vertical plates are fixed on the column cap by welding. A circular hole is opened on the upper part of the vertical plate and connected to a pin shaft. The middle part and both ends of the pin shaft are respectively connected to the main cable and the diagonal member. The processing technology of this flexible photovoltaic bracket involves steel plate cutting, bolt connection, steel plate welding assembly, etc. Its production process is relatively complicated, and the number of steel plate parts is relatively large. In addition, the column cap is connected to the top of the column by welding or bolting, and there are still problems such as difficult to control welding quality or cumbersome bolt connection process and many spare parts.

[0054] The core of the present invention is to disclose a flexible photovoltaic bracket to reduce production costs and improve quality.

[0055] Another object of the present invention is to disclose a photovoltaic system including the above-mentioned flexible photovoltaic support.

[0056] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0057] Combination Figure 1-Figure 16 The flexible photovoltaic support disclosed in the present invention includes a connection assembly and a plurality of photovoltaic support monomers arranged in parallel and at intervals. The connection assembly is connected between two adjacent photovoltaic support monomers, and each photovoltaic support monomer includes a cable assembly, a support assembly and a wind-resistant assembly 300, wherein the cable assembly includes a main cable 100 and a diagonal member 110, and the photovoltaic panel 400 is used to be arranged 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 between the two groups of end supports 200, and the middle of the main cable 100 is connected to each group of middle supports 210, and the two ends of the main cable 100 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 being tilted due to uneven force.

[0058] 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 . A main cable mounting hole and a pin mounting hole arranged at an angle are provided on the end column 201, and the axes of the main cable mounting hole and the pin mounting hole are usually arranged vertically, and the main cable mounting hole and the pin mounting hole are connected, a first connecting hole is provided on the main cable anchor 206, and a second connecting hole is provided on the side wall of the pin 202, the pin 202 is penetrated into the pin mounting hole, the end of the main cable 100 passes through the first connecting hole and the second connecting hole, and the main cable anchor 206 is fixedly connected to the main cable 100, and the main cable anchor 206 abuts against the pin 202, and the main cable anchor 206 can be limited at the main cable mounting hole by the pin 202, thereby realizing the fixation of the main cable 100 and the end bracket 200.

[0059] 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 activity requirements of the main cable 100 and the main cable anchor 206 relative to the end column 201±45°. The opening methods of 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. It is preferred to use laser cutting to open the hole, which has reliable quality control and high processing efficiency.

[0060] 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 between two groups of end brackets 200 at intervals to enhance the wind-resistant performance of the flexible photovoltaic bracket.

[0061] 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 flow, improving the processing efficiency, and reducing the cost.

[0062] The types of the inclined-stayed components 110 include but are not limited to inclined cables, steel wire ropes, inclined-stayed steel pipes, inclined-stayed steel bars, and other components that can provide a certain pre-tension. Figure 1 Each cable assembly includes two main cables 100 and four diagonal members 110. Each photovoltaic panel 400 is laid flat along the extension direction of the main cable 100 and fixed on the main cable 100. The number of the middle bracket 210 and the wind-resistant assembly 300 can be set according to actual needs, and will not be listed one by one in this article.

[0063] In a specific embodiment disclosed in the present invention, Figure 1 The wind-resistant components 300 and the middle brackets 210 are arranged sequentially 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.

[0064] Combination Figure 2 and Figure 7The 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 shaft 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 reinforce the column head of the end column 201, a combination of Figure 3 The end bracket 200 also includes a cover plate 204, which is arranged on the top of the end column 201 and is 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.

[0065] In one embodiment, the cover plate 204 includes a top plate and two side plates, the two side plates are vertically arranged at both ends of the top plate, and a avoidance hole connected to the pin shaft mounting hole is opened on the side plate, and the side plate is welded to the end column 201, which is in contact with the pin shaft 202, which can effectively enhance the structural strength at the pin shaft mounting hole and prevent the steel plate at the pin shaft mounting hole from yielding and deforming when subjected to force. In addition, the arrangement of the top plate can effectively prevent excessive adhesion of external impurities to the position where the pin shaft 202 is located. Specifically, the cover plate 204 can be prepared by bending a steel plate.

[0066] Those skilled in the art will appreciate that, although the cover plate 204 is connected to the end column 201 by welding, 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 will not lead to a significant increase in costs.

[0067] 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 shaft 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 shaft 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 a rectangle or a circle, and it only needs to be able to allow the end surface of the main cable anchor 206 facing the pin shaft 202 to be completely attached. In other embodiments, combined with Figure 3 and Figure 6The end bracket 200 also includes a holder 205, which is provided with a third connection hole and 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 fits with the end surface of the main cable anchor 206, and the end of the holder 205 facing the pin 202 has a second surface that fits with the circumferential side wall of the pin 202. The first surface is a plane, 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 fits with the end surface of the main cable anchor 206, and the second surface fits with the circumferential side wall of the pin 202.

[0068] It can be understood by those skilled in the art that, compared with the solution of adding a socket 205, the solution of setting a positioning plane 2021 on the circumferential side wall of the pin shaft 202 occupies less space, has lower cost, and the main cable anchor 206 is easier to arrange inside the end bracket 200, which is the preferred solution.

[0069] 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 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 202 for fixation, which effectively reduces the production cost and is easy to install.

[0070] In a specific embodiment disclosed in the present invention, the end bracket 200 includes two end columns 201 arranged in parallel and at intervals and at least one end support beam 208, and the end support beam 208 is connected between the two end columns 201. The end support beam 208 can be provided to connect the two end brackets 200 to form a whole, thereby improving the overall structural strength of the end bracket 200.

[0071] To further optimize the solution, a plurality of 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 hole and the position adjustment hole, so that the end column 201 and the end support beam 208 are hingedly connected. The provision of a plurality of position adjustment holes facilitates the adjustment of the connection position of the end support beam 208, thereby adapting to different installation scenarios. Alternatively, waist-shaped holes arranged along the extension direction of the end column 201 are provided on 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.

[0072] In one embodiment, in combination Figure 7The two ends of the end support beam 208 are respectively hinged with a mounting seat, and the mounting seat is connected with 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.

[0073] Combination Figure 7 and Figure 8 In order to improve the overall structural strength of the flexible photovoltaic support, the connection assembly includes an end connection beam 209, and the two ends of the end connection beam 209 are respectively connected to the end columns 201 of two adjacent photovoltaic support monomers. The end connection beam 209 can be arranged to connect the end columns 201 of adjacent photovoltaic support monomers to form a whole, thereby improving the overall structural strength of the flexible photovoltaic support. The end connection beam 209 can share the same set of position adjustment holes with the above-mentioned end support beam 208 to adjust the installation position.

[0074] In a specific embodiment disclosed in the present invention, Figure 11-Figure 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 be fixed 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. Exemplary, Fig.11 , Fig.12 , Fig.14 and Fig.16 A solution is shown 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 bracket 310.

[0075] 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 arranged at intervals. The main cable 100 is set on the second bracket 312. The third bracket 313 is connected between the middle positions of the first bracket 311 and the second bracket 312 to support the first bracket 311 and the second bracket 312 to ensure the interval between the two. The first bracket 311, the second bracket 312 and the third bracket 313 can all be made of steel.

[0076] In one embodiment, in combination Figure 11-13 , the third bracket 313 is arranged vertically with the first bracket 311, and the wind-resistant bracket 310 is arched as a whole; in another embodiment, combined with Figure 14-16Both 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, while the former uses less materials and has lower costs.

[0077] Further optimize the solution, combined with Fig.12 and Fig.15 The connection assembly 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 frames 310 of two adjacent photovoltaic frame monomers.
