Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic technology, and particularly to a flexible photovoltaic support and a photovoltaic system. Background Art

[0002] In recent years, the photovoltaic industry has rapidly emerged with the rapid development of the renewable energy field. Due to its ability to adapt to complex terrains, flexible photovoltaic supports have shown great advantages in the construction of photovoltaic power stations. A flexible photovoltaic support uses steel strands as the main load-bearing cables and is fixed by end supports composed of steel beams and side anchors. Since the load-bearing cables have a relatively long span (10m - 60m), it is necessary to build multiple support steel frame structures in the middle to form middle supports for supporting and fixing the load-bearing cables. The end supports also play a role in connecting the load-bearing cables and the stay cables, and the load-bearing cables are connected to the photovoltaic panels through connectors to form an integral whole.

[0003] In an existing flexible photovoltaic support, the top of the column of the end support fixes the column head by welding or bolt connection, and two vertical plates are fixed on the column head by welding. Round holes are opened in the upper part of the vertical plates and are connected with pin shafts. The middle part and the two end parts of the pin shaft are respectively connected to the main cable and the stay cable member. The processing technology of this flexible photovoltaic support involves steel plate cutting, bolt connection, steel plate welding and assembly, etc. Its manufacturing process is relatively complex, and the number of steel plate parts is large. In addition, the connection between the column head and the top of the column by welding or bolt connection also has problems such as difficult control of welding quality or cumbersome bolt connection procedures and many spare parts.

[0053] The core of the present invention lies in disclosing 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 above flexible photovoltaic bracket.

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0056] Combined with Figures 1 - 16 , the flexible photovoltaic support disclosed by the present invention includes a connection component and a plurality of photovoltaic support monomers arranged in parallel and at intervals. The connection component is connected between two adjacent photovoltaic support monomers, and each photovoltaic support monomer includes a cable component, a support component, and a wind resistance component 300. Among them, the cable component includes a main cable 100 and a stay member 110. The photovoltaic panel 400 is configured to be arranged on the main cable 100. The support component 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 of the main cable 100 is connected to each group of middle supports 210. The two ends of the main cable 100 are respectively connected to the two groups of end supports 200. The first end of the stay member 110 is connected to the end support 200, and the second end is connected to the ground. The stay 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 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 installation hole and a pin installation hole are formed through the end column 201 at an included angle. The axes of the main cable installation hole and the pin installation hole are generally perpendicular to each other and communicate with each other. A first connection hole is formed through the main cable anchor 206, and a second connection hole is formed through the side wall of the pin 202. The pin 202 is inserted into the pin installation hole. The end of the main cable 100 passes through the first connection hole and the second connection hole, and the main cable anchor 206 is fixedly connected to the main cable 100. The main cable anchor 206 abuts against the pin 202. The main cable anchor 206 can be limited at the main cable installation hole through the pin 202, thereby realizing the fixation of the main cable 100 and the end support 200.

[0058] Among them, the aperture of the pin installation hole is set with reference to the diameter of the pin 202, and it only needs to ensure that the pin 202 can pass through the pin installation hole and can rotate. The cross-section of the pin installation hole includes but is not limited to a circle. The main cable installation hole can be an oblong hole, a round hole, a rectangular hole, a square hole, etc. The main cable installation hole needs to meet the movement requirements of the main cable 100 and the main cable anchor 206 relative to the end column 201 by ±45°. The opening methods of the pin installation hole and the main cable installation hole include but are not limited to laser cutting, steel structure thermal cutting, flame cutting, cold cutting, water cutting, etc. It is preferably to use laser cutting to open the hole, with reliable quality control and high processing efficiency.

[0059] The wind resistance components 300 are multiple groups and are connected to the main cable 100, and each group of wind resistance components 300 is arranged at intervals between the two groups of end supports 200 to enhance the wind resistance performance of the flexible photovoltaic support.

[0060] Compared with the prior art, in the present invention, the main cable 100 is fixed by opening holes in the end column 201, and the acting force of the main cable 100 can directly act on the end column 201 through the pin shaft 202, ensuring the integrity of the structure at the head position of the end column 201. Furthermore, the reliability of the structure is greatly improved, the number of parts is reduced, the processing flow is simplified, the processing efficiency is increased, and the cost is reduced.

[0061] Among them, the types of the stay members 110 include, but are not limited to, stay cables, steel wire ropes, stay steel pipes, stay steel bars, etc., which can provide a certain pre-tension force. Considering the reduction of production costs, combined with Figure 1 , each cable assembly includes two main cables 100 and four stay members 110. Each photovoltaic panel 400 is tiled and fixed on the main cable 100 at intervals along the extension direction of the main cable 100. The number of the middle brackets 210 and the wind-resistant assemblies 300 can be set according to actual requirements and will not be listed one by one herein.

[0062] In a specific embodiment disclosed in the present invention, combined with Figure 1 , the wind-resistant assemblies 300 and the middle brackets 210 are arranged in sequence and alternately between the two groups of end brackets 200, strengthening the stability of the entire structure of the flexible photovoltaic support provided in this embodiment, enabling it to have a strong ability to resist strong wind and bad weather, reducing the risk of hidden cracks in the photovoltaic panels 400 installed on the flexible photovoltaic support, and ensuring the normal operation of the photovoltaic system.

[0063] Combined with 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 installation hole and the pin shaft installation hole are both arranged at the top of the end column 201. Since the end column 201 is usually a metal pipe such as a hollow round pipe or a square pipe, the structural strength at the head position of the top of the end column 201 will be reduced after opening the holes. Therefore, in order to reinforce the head of the end column 201, combined with Figure 3 , the end bracket 200 further includes a cover plate 204. The cover plate 204 is arranged at 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 at the 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 includes a top plate and two side plates. The two side plates are vertically arranged at both ends of the top plate, and an avoidance hole communicating with the pin installation hole is formed in the side plates. The side plates are welded to the end columns 201 and are in contact with the pin 202, which can effectively enhance the structural strength at the pin installation hole and prevent the steel plate at the pin installation hole from yielding and deforming when stressed. In addition, the arrangement of the top plate can effectively prevent excessive adhesion of external impurities to the position where the pin 202 is located. Specifically, the cover plate 204 can be prepared by bending a steel plate.

[0065] Those skilled in the art can understand that although the cover plate 204 is welded to the end column 201, since the main purpose of setting the cover plate 204 is to reinforce, and the welded part is not the main stress part of the end column 201, therefore, the quality requirement for the welding of the cover plate 204 is not high and will not cause a substantial increase in cost.

[0066] Further, since the pin 202 is cylindrical, in order to facilitate the abutting and fixing of the main cable anchor 206 to the circumferential side wall of the pin 202, in some embodiments, in combination with 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 support is assembled, the end face of the main cable anchor 206 facing the pin 202 abuts and fits against the positioning plane 2021. Specifically, the positioning plane 2021 can be formed by cutting or grinding, etc. And for the convenience of assembly, the positioning plane 2021 can be two and are symmetrically arranged at both ends of the second connection hole. The shape of the positioning plane 2021 is not limited to a rectangle and a circle, as long as it can allow the end face of the main cable anchor 206 facing the pin 202 to completely adhere. In some other embodiments, in combination with Figure 3 and Figure 6 , the end support 200 further includes a clamping seat 205. A third connection hole is formed through the clamping seat 205 and is arranged between the main cable anchor 206 and the pin 202. The main cable 100 passes through the third connection hole. One end of the clamping seat 205 facing the main cable anchor 206 has a first fitting surface that fits against the end face of the main cable anchor 206, and one end of the clamping seat 205 facing the pin 202 has a second fitting surface that fits against the circumferential side wall of the pin 202. Among them, the first fitting surface is a plane, and the second fitting surface is a curved surface. After the flexible photovoltaic support is assembled, the clamping seat 205 is pressed between the main cable anchor 206 and the pin 202, and the first fitting surface fits against the end face of the main cable anchor 206, and the second fitting surface fits against the circumferential side wall of the pin 202.

[0067] Those skilled in the art can understand that, compared with the solution of adding a card seat 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 be arranged inside the end bracket 200, which is the preferred solution.

[0068] The stay cable member 110 is hingedly connected to the end bracket 200 to facilitate fine adjustment of the angle. Figure 3 Combined with Figure 3 , the end of the stay cable member 110 is connected to the swivel bolt 111. A fourth connection hole is provided on the swivel bolt 111. The end of the pin shaft 202 passes through the fourth connection hole and is limited by a locking pin 203. The main cable 100 and the stay cable member 110 share the same pin shaft 202 for fixation, effectively reducing the production cost and being convenient for installation.

[0069] In a specific embodiment disclosed by 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. The end support beam 208 is connected between the two end columns 201. By providing the end support beam 208, the two end brackets 200 can be connected to form an integral body, thereby improving the overall structural strength of the end bracket 200.

[0070] In a further optimized 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 extending direction of the end column 201; hinge holes are provided at both ends of the end support beam 208, and a 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 a plurality of position adjustment holes facilitates adjustment of the connection position of the end support beam 208, thereby adapting to different installation scenarios. Alternatively, a waist-shaped hole is provided on the end column 201 along the extending direction of the end column 201, and the end support beam 208 is tightened by bolts at different positions of the waist-shaped hole to adjust the installation position.

[0071] In an embodiment, Figure 7 Combined with Figure 7 , mounting seats are respectively hinged at both ends of the end support beam 208, and the mounting seats are bolted to the position adjustment holes, which can also realize the adjustment of the installation position of the end support beam 208 and the end column 201.

[0072] Combined with Figure 7 and Figure 8, To improve the overall structural strength of the flexible photovoltaic support, the connection component includes an end connection beam 209. The two ends of the end connection beam 209 are respectively connected to the end columns 201 of two adjacent photovoltaic support monomers. By providing the end connection beam 209, the end columns 201 of adjacent photovoltaic support monomers can be connected to form a whole, thereby improving the overall structural strength of the flexible photovoltaic support. Among them, the end connection beam 209 can share the same set of position adjustment holes with the above-mentioned end support beam 208 for adjusting the installation position.

[0073] In a specific embodiment disclosed in the present invention, in combination with Figures 11 - 16 , the wind resistance component 300 includes a wind resistance support 310, a first ground pile 330, and at least two connection cables 320. The main cable 100 is connected to the wind resistance support 310. The first ground pile 330 is used to be fixed on the ground to ensure the stability of the wind resistance support 310. The two ends of the connection cable 320 are respectively hinged to the wind resistance support 310 and the first ground pile 330. Different connection cables 320 are connected to different positions of the wind resistance support 310, and different connection cables 320 have different lengths, so that an installation inclination angle adapted to the installation of the photovoltaic panel 400 can be formed on the wind resistance support 310. Exemplarily, Figure 11 , Figure 12 , Figure 14 and Figure 16 show a solution in which the number of connection cables 320 is two, and the two connection cables 320 are respectively connected to the two ends of the wind resistance support 310.

[0074] Among them, the wind resistance support 310 includes a first support 311, a second support 312, and a third support 313. The two ends of the first support 311 are connected to the connection cable 320. The two ends of the second support 312 are both connected to the first support 311, and the middle position is arranged parallel and spaced from the first support 311. The main cable 100 is arranged on the second support 312; the third support 313 is connected between the middle positions of the first support 311 and the second support 312 to support the first support 311 and the second support 312 and ensure the interval between the two. The first support 311, the second support 312, and the third support 313 can all be prepared from steel.

[0075] In one embodiment, in combination with Figures 11 - 13 , the third support 313 is arranged perpendicular to the first support 311, and the wind resistance support 310 is in an overall bow shape; in another embodiment, in combination with Figures 14 - 16 , the two ends of the third support 313 are both connected to the second support 312, and the middle position is connected to the first support 311. The wind resistance support 310 is in an overall butterfly shape. The latter has more triangular structures than the former and better stability. The former uses less materials and has lower costs.

[0076] For a further optimized solution, in combination withFigure 12 and Figure 15 The connecting component includes a wind-resistant frame connecting rod 340. Both ends of the wind-resistant frame connecting rod 340 are respectively connected to the wind-resistant brackets 310 of two adjacent single photovoltaic brackets.

[0077] To improve versatility, a plurality of 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. 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 realize the adjustment of the installation position.
