[0003] Photovoltaic support system is a support used to support solar panels (also known as photovoltaic modules) in solar photovoltaic power generation systems. Traditional photovoltaic support systems are rigid supports, while flexible photovoltaic supports are cable structures that stretch cables between two fixed points and use a rigid foundation to provide reaction force at the two fixed points. Flexible photovoltaic supports have a simple structure and light weight, and can be installed over a large span, avoiding unfavorable geographical factors such as undulating mountains and high vegetation, thus broadening the installation range of solar photovoltaic power generation systems.

[0004] Existing flexible photovoltaic brackets mainly use prestressed first and second main cables as load-bearing components to directly support solar panels (also known as photovoltaic modules), and stabilizing cables provide auxiliary support. Flexible photovoltaic brackets have disadvantages such as poor structural stability and poor wind resistance, which makes photovoltaic modules prone to hidden cracks and flipping problems.

[0045] Please refer to Figures 1-8 。

[0046] The flexible photovoltaic support system includes at least two flexible photovoltaic supports arranged side by side. The flexible photovoltaic support includes end supports, middle supports and cable trusses. The cable truss includes a first main cable 2, a second main cable 3, a stabilizing cable 4 and a square pyramid support.

[0047] Among them, the number of end supports is two and they are arranged oppositely. The middle support is located between the two end supports. The number of middle supports is set according to actual needs. The number of the first main cable 2, the second main cable 3 and the stabilizing cable 4 is one each.

[0048] The end supports are fixed on the ground foundation. The ground foundation can adopt pipe piles or other forms of tensile foundation to ensure the stability of the flexible photovoltaic support during ground installation;

[0049] The middle support is also fixed on the ground foundation and is used to support the middle positions of the first main cable 2, the second main cable 3 and the stabilizing cable 4;

[0050] The first main cable 2, the second main cable 3 and the stabilizing cable 4 are located between the two end supports and the two ends of the first main cable 2, the second main cable 3 and the stabilizing cable 4 are respectively fixed on the two end supports. Specifically, the first end in the length direction of the first main cable 2 is connected to the first end in the width direction of one of the end supports, and the second end in the length direction of the first main cable 2 is connected to the first end in the width direction of the other end support. The first end in the length direction of the second main cable 3 is connected to the second end in the width direction of one of the end supports, and the second end in the length direction of the second main cable 3 is connected to the second end in the width direction of the other end support. The first ends in the width direction of the two end supports are on the same side in the length direction of the first main cable 2, and the second ends in the width direction of the two end supports are on the same side in the length direction of the first main cable 2. The first main cable 2 is parallel to the second main cable 3. The stabilizing cable 4 is located between the first main cable 2 and the second main cable 3. The first end in the length direction of the stabilizing cable 4 is connected to the middle part in the width direction of one of the end supports, and the second end in the length direction of the stabilizing cable 4 is connected to the middle part in the width direction of the other end support.

[0051] The first main cable 2 and the second main cable 3 are connected to the photovoltaic modules and act as load-bearing cables to support the weight of the photovoltaic modules and transfer the weight of the photovoltaic modules to the end supports.

[0052] The stabilizing cable 4 is set between the first main cable 2 and the second main cable 3 with the original sag, where the original sag is determined according to the force requirements. The stabilizing cable 4 cooperates with the first main cable 2 and the second main cable 3 to improve the stability of the flexible photovoltaic support and its ability to resist external forces.

[0053] The square pyramid support is used to fix the first main cable 2, the second main cable 3 and the stabilizing cable 4. The square pyramid support has a quadrilateral base and four triangular sides. As Figure 2 shown, the square pyramid support is set upside down, and the quadrilateral base is located above the triangular sides. The first side of the quadrilateral base parallel to the first main cable 2 is connected to the first main cable 2, the second side of the quadrilateral base parallel to the second main cable 3 is connected to the second main cable 3, and the third vertex of the square pyramid support opposite to the quadrilateral base is connected to the stabilizing cable 4. Preferably, the two first vertices of the first side are connected to the first main cable 2, and the two second vertices of the second side are connected to the second main cable 3.

[0054] At least one square pyramid support is arranged along the length direction of the first main cable 2. On the basis of satisfying the fixation of the first main cable 2 and the second main cable 3, the square pyramid support can also support the first main cable 2 and the second main cable 3, and the two sides of the square pyramid support perpendicular to the first main cable 2 support the first main cable 2 and the second main cable 3 at the same time, enhancing the stability and wind resistance of the flexible photovoltaic support along its own length direction, that is, the length direction of the first main cable 2.

[0055] The two sides of the square pyramid support perpendicular to the first main cable 2 and the second main cable 3 and located between the first main cable 2 and the second main cable 3 are triangles, and the two triangles are arranged oppositely. The sides at the upper ends of the triangles are respectively connected to the first main cable 2 and the second main cable 3. Preferably, the vertices at the upper ends of the triangles are respectively connected to the first main cable 2 and the second main cable 3, and the vertices at the lower ends of the triangles are connected to the stabilizing cable 4. The shape of the square pyramid support is determined by the positions of the first main cable 2, the second main cable 3 and the stabilizing cable 4.

[0056] The square pyramid support 1 has two connection positions with both the first main cable 2 and the second main cable 3, enhancing the stability of the first main cable 2 and the second main cable 3, and further enhancing the stability of the support of the first main cable 2 and the second main cable 3 for the photovoltaic modules.

[0057] The flexible photovoltaic support system disclosed in this application further includes a first wind-resistant cable 7. As Figure 2 shown, the first wind-resistant cable 7 spans multiple flexible photovoltaic supports, connecting the cable trusses of the entire flexible photovoltaic support system to form an integral cable truss system for the entire flexible photovoltaic support system, so as to enhance the stability and wind resistance of the entire flexible photovoltaic support system and ensure the stable operation of the photovoltaic array.

[0058] The first wind-resistant cable 7 spans across the flexible photovoltaic support system. Both ends of the first wind-resistant cable 7 are anchored to the ground foundation, and the middle part of the first wind-resistant cable 7 is connected to the third vertices of the four-pyramid supports 1 of multiple flexible photovoltaic supports. Along the length direction perpendicular to the stabilizing cable 4, the first wind-resistant cable 7 connects the four-pyramid supports 1 of multiple flexible photovoltaic supports in series. At the same time, the end of the first wind-resistant cable 7 can apply an anchoring force to enhance the stability and wind resistance of the flexible photovoltaic support system along the length direction perpendicular to the stabilizing cable 4.

[0059] For the flexible photovoltaic support system disclosed in this application, the stability and wind resistance of the flexible photovoltaic support along its own length direction are enhanced through the four-pyramid supports of the cable truss of the flexible photovoltaic support. At the same time, the first wind-resistant cable 7 makes the flexible photovoltaic support system form a whole in the length direction perpendicular to the flexible photovoltaic support, and applies an anchoring force to the entire flexible photovoltaic support system to enhance the wind resistance and stability of the flexible photovoltaic support system along the length direction perpendicular to the flexible photovoltaic support. In summary, the flexible photovoltaic support system disclosed in this application cooperates with the four-pyramid support and the first wind-resistant cable 7 to enhance the wind resistance and stability of the flexible photovoltaic support system in the length direction of the flexible photovoltaic support and the length direction perpendicular to the flexible photovoltaic support, effectively reducing the risk of hidden cracks and overturning of the photovoltaic modules.

[0060] The four-pyramid support 1 can be a structure with all four sides of the quadrilateral bottom surface closed as shown in Figure 4 , or a structure with the sides of the quadrilateral bottom surface that are not connected to the first main cable 2 and the second main cable 3 closed, and the other two sides not closed, and short support rods are arranged on the unclosed sides. Figure 5 The positions of the four-pyramid supports of multiple flexible photovoltaic supports of the flexible photovoltaic support system correspond one by one. As shown in

[0061] and Figure 1 and 6 , there are multiple rows of four-pyramid supports along the length direction of the flexible photovoltaic support. The first wind-resistant cable 7 can be connected to only one row of four-pyramid supports, or can be connected to two rows or even multiple rows of four-pyramid supports.

[0062] To further optimize the above technical solution, the flexible photovoltaic support system disclosed in this application further includes a V-shaped strut 5. The V-shaped strut 5 is located between adjacent two flexible photovoltaic supports and is used to connect the four-pyramid supports corresponding to the positions of adjacent two flexible photovoltaic supports, that is, the adjacent two four-pyramid supports in each row of four-pyramid supports are connected by a V-shaped strut.

[0063] The V-shaped strut 5 is used to connect the four-pyramid brackets corresponding to the positions of two adjacent flexible photovoltaic brackets, so that the flexible photovoltaic bracket system forms an integral cable truss system. The V-shaped strut 5 is used to rigidly support the flexible photovoltaic bracket in the direction perpendicular to the length of the flexible photovoltaic bracket, reducing the risk of the flexible photovoltaic bracket tipping over and shaking, and cooperating with the first anti-wind cable 7 providing flexible connection, further enhancing the stability and wind resistance of the entire flexible photovoltaic bracket system, and ensuring the stable operation of the photovoltaic array.

[0064] The plane where the V-shaped strut 5 is located can be perpendicular to the plane where the first main cable 2 and the second main cable 3 are located, or can be inclined relative to the plane where the first main cable 2 and the second main cable 3 are located.

[0065] Preferably, the plane where the V-shaped strut 5 is located is inclined relative to the plane where the first main cable 2 and the second main cable 3 are located. The V-shaped strut 5 has an open end and a closed end. The open end of the V-shaped strut 5 is closer to the quadrilateral bottom surface of the four-pyramid bracket than the closed end of the V-shaped strut 5, and the height of the open end of the V-shaped strut 5 is higher than the height of the closed end of the V-shaped strut 5.

[0066] The flexible photovoltaic bracket system disclosed in this application is applicable to scenarios such as fish ponds, flat lands or parking lots, and is also applicable to uneven scenarios such as mountain slopes.

[0067] The V-shaped strut 5 is arranged obliquely to provide a supporting force to the adjacent flexible photovoltaic brackets. This supporting force has horizontal and vertical components along the direction perpendicular to the length of the first main cable 2. It can not only provide a horizontal supporting force to the flexible photovoltaic brackets, but also provide a vertical supporting force to the flexible photovoltaic brackets, reducing the shaking of the photovoltaic modules in the horizontal and vertical directions, and reducing the risk of the photovoltaic modules cracking and tipping over.

[0068] The V-shaped strut 5 can be a first reinforcing rod 13 formed by integral bending, or can be made of two welded rods.

[0069] In some embodiments of the present application, the closed end of the V-shaped strut 5 is connected to the third vertex of the four-pyramid bracket of a flexible photovoltaic bracket, and the two free ends of the open end of the V-shaped strut 5 are connected to the first vertex or the second vertex of the four-pyramid bracket of the adjacent flexible photovoltaic bracket.

[0070] The orientations of the open ends of the V-shaped struts 5 located between two adjacent flexible photovoltaic brackets can be the same or different. In the embodiments where the orientations of the open ends of the V-shaped struts 5 located between two adjacent flexible photovoltaic brackets are the same, the orientations of the open ends of the V-shaped struts 5 located between different flexible photovoltaic brackets can be the same or different.

[0071] The V-shaped strut 5 and the four-pyramid bracket can be fixedly connected or detachably connected.

[0072] In an embodiment where the V-shaped strut 5 is fixedly connected to the square pyramid support, the V-shaped strut 5 and the square pyramid support may be connected by welding.

[0073] In an embodiment where the V-shaped strut 5 is detachably connected to the square pyramid support, the V-shaped strut 5 and the square pyramid support may be connected by bolts.

[0074] The flexible photovoltaic support system disclosed in this application further includes a second wind-resistant cable 6. The second wind-resistant cable 6 is located between two adjacent flexible photovoltaic supports, and there are various ways to arrange the second wind-resistant cable 6.

[0075] First, one end of the second wind-resistant cable 6 is connected to the end support of one of the flexible photovoltaic supports, and the other end of the second wind-resistant cable 6 is connected to the square pyramid support adjacent to the other flexible photovoltaic support and the end support;

[0076] Second, one end of the second wind-resistant cable 6 is connected to the middle support of one of the flexible photovoltaic supports, and the other end of the second wind-resistant cable 6 is connected to the square pyramid support adjacent to the other flexible photovoltaic support and the middle support;

[0077] Third, one end of the second wind-resistant cable 6 is connected to the end support of one of the flexible photovoltaic supports, and the other end of the second wind-resistant cable 6 is connected to the square pyramid support adjacent to the other flexible photovoltaic support and the end support. At the same time, one end of the second wind-resistant cable 6 is connected to the middle support of one of the flexible photovoltaic supports, and the other end of the second wind-resistant cable 6 is connected to the square pyramid support adjacent to the other flexible photovoltaic support and the middle support. Preferably, the second wind-resistant cables 6 connected to the end support and the middle support are located on the same side of the flexible photovoltaic support;

[0078] Fourth, both ends of the second wind-resistant cable 6 are respectively connected to the end support and the middle support of one of the flexible photovoltaic supports, and the middle of the second wind-resistant cable 6 is connected to the square pyramid support of the other flexible photovoltaic support located between the end support and the middle support.

[0079] The second wind-resistant cable 6 can provide forces along the length direction of the flexible photovoltaic support and perpendicular to the length direction of the flexible photovoltaic support to two adjacent flexible photovoltaic supports, further enhancing the integrity of the flexible photovoltaic support system. The force borne by the second wind-resistant cable 6 is finally transmitted to the ground foundation through the end support and / or the middle support; the second wind-resistant cable 6 cooperates with the first wind-resistant cable 7 and the V-shaped strut 5 to form an overall cable truss system for the entire flexible photovoltaic support system, so as to enhance the stability and wind resistance of the entire flexible photovoltaic support system and ensure the stable operation of the photovoltaic array.

[0080] The flexible photovoltaic supports at both ends of the flexible photovoltaic support system bear greater wind force. Therefore, it is necessary to increase the strength of the flexible photovoltaic supports on the outer side of the flexible photovoltaic support system. Therefore, in some embodiments of the present application, along the length direction perpendicular to the first main cable 2, the setting spacing of the square pyramid supports on the flexible photovoltaic supports in the middle of the flexible photovoltaic support system is greater than the setting spacing of the square pyramid supports on the flexible photovoltaic supports at both ends of the flexible photovoltaic support system.

[0081] In some embodiments of the present application, the setting spacing of the square pyramid supports of at least two flexible photovoltaic supports on the outer side of the flexible photovoltaic support system is different from the setting spacing of the square pyramid supports of the flexible photovoltaic supports in the middle of the flexible photovoltaic support system.

[0082] As Figure 6 shown, in the length direction perpendicular to the flexible photovoltaic support, the square pyramid supports of the flexible photovoltaic supports on the outer side of the flexible photovoltaic support system are symmetrically distributed on both sides of the square pyramid supports of the flexible photovoltaic supports in the middle of the flexible photovoltaic support system.

[0083] In the embodiments where the setting spacing of the square pyramid supports of the flexible photovoltaic supports on the outer side of the flexible photovoltaic support system is different from the setting spacing of the square pyramid supports of the flexible photovoltaic supports in the middle of the flexible photovoltaic support system, the end of the first anti-wind cable 7 forks. The end of the first anti-wind cable 7 is connected to the square pyramid supports of the flexible photovoltaic supports on the outer side of the flexible photovoltaic support system, and the middle of the first anti-wind cable 7 is connected to the square pyramid supports of the flexible photovoltaic supports in the middle of the flexible photovoltaic support system. The setting direction of the first anti-wind cable 7 is perpendicular to the length direction of the first main cable 2.

[0084] In this embodiment, the first anti-wind cable 7 has four cables. The four cables are branched at the end, and each branch has two cables. Each branch is respectively connected to the outer square pyramid support and then divided into two strands to be anchored to the ground foundation. The four cables are combined into one strand in the middle and connected to the square pyramid supports in the middle of the flexible photovoltaic support system.

[0085] In the embodiments where the square pyramid supports of multiple flexible photovoltaic supports in the flexible photovoltaic support system are equally spaced, the first anti-wind cable 7 is arranged along the length direction perpendicular to the flexible photovoltaic support, and the first anti-wind cable 7 is used to connect a row of square pyramid supports. In this embodiment, the first anti-wind cable 7 has two cables. The two cables are branched at the end, and the branched first anti-wind cable 7 is anchored to the ground foundation. The two cables are combined into one strand in the middle and connected to a row of square pyramid supports.

[0086] In some embodiments of the present application, strengthening bars can be arranged on the triangular sides and / or the quadrilateral bases of the square pyramid supports to enhance the strength of the square pyramid supports.

[0087] In order to reduce the difficulty of connecting the first main cable 2 and the second main cable 3 to the square pyramid support, in some embodiments of the present application, the length of the mounting rod of the square pyramid support for mounting the first main cable 2 and the second main cable 3 is designed to be relatively long, extending a certain distance from the quadrilateral bottom surface, and the extended part is used to connect to the first main cable 2 and the second main cable 3.

[0088] The square pyramid support can be an integral structure support that cannot be disassembled; it can also be an assembled support, which is convenient for maintenance or replacement as needed when some members need to be repaired or replaced.

[0089] Preferably, the square pyramid support is an aluminum alloy support, a stainless steel support or other metal supports.

[0090] In some embodiments of the present application, the square pyramid support is connected to the first main cable 2, the second main cable 3 and the stabilizing cable 4 through hoop fasteners.

[0091] A fixing ring is arranged at the position of the third vertex of the square pyramid support, and the first wind-resistant cable 7 is connected to the square pyramid support through the fixing ring.

[0092] The above description is only the preferred embodiments of the present application and an explanation of the applied technical principles, and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. The scope of the application involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above application concept.
