Description

Technical Field

[0001] This utility model relates to a novel flexible photovoltaic support, belonging to the field of photovoltaic support technology. Background Technology

[0002] With the growth of global energy demand and the increasing emphasis on renewable energy, photovoltaic (PV) power generation, as a green, clean, and sustainable form of energy utilization, has been widely adopted. As a key component of PV power plants, the performance of PV support structures directly affects the operational stability and power generation efficiency of the PV system. Traditional PV support structures typically employ rigid structures, which, while providing sufficient support rigidity and stability, exhibit poor adaptability and flexibility when facing complex terrain or extreme weather conditions. Furthermore, they require a high degree of ground flatness, resulting in high construction costs.

[0003] With technological advancements, flexible photovoltaic (PV) mounting systems have gradually become a highly regarded alternative. Due to their lightweight, adaptability, and ease of installation, flexible mounting systems have demonstrated significant potential, particularly in complex terrains and areas with high wind loads.

[0004] However, most flexible photovoltaic (PV) mounting systems on the market still suffer from the following problems: 1. Insufficient stability: Under the influence of external environmental forces such as strong winds, flexible mounting systems are prone to significant vibrations, leading to uneven stress and torsional deformation, which in turn causes the system to become unstable; 2. Low component safety: Frequent vibrations and deformations may cause PV modules to flip or fall off, posing safety hazards and increasing maintenance and repair costs; 3. Decreased economic benefits: The high maintenance frequency of flexible mounting systems not only increases operation and maintenance costs but also affects the investment returns of PV power plants. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the prior art by providing a novel flexible photovoltaic support system. This flexible photovoltaic support system can operate stably under various environmental conditions, while reducing the complexity and cost of construction and maintenance. This support system is particularly suitable for large-scale photovoltaic power plants in complex terrain and high wind load areas, and has high economic efficiency and long-term reliability.

[0006] The technical solution provided by this utility model to solve the above-mentioned technical problems is: a novel flexible photovoltaic support, comprising:

[0007] The supporting structure includes a left longitudinal column, a right longitudinal column, an upper transverse column, and a lower transverse column, and steel beams are provided on both the left longitudinal column and the right longitudinal column;

[0008] The cable structure includes an upper load-bearing cable, a middle stabilizing cable, a lower wind-resistant cable, and transverse connecting cables. The upper load-bearing cable is connected at both ends to two steel crossbeams. The middle stabilizing cable is connected at both ends to two steel crossbeams and is located below the upper load-bearing cable. The lower wind-resistant cable is connected at both ends to a left longitudinal column and a right longitudinal column and is located below the middle stabilizing cable. The transverse connecting cables are connected at both ends to an upper transverse column and a lower transverse column and are located below the lower wind-resistant cable.

[0009] The Y-shaped connector is connected to the upper load-bearing cable, the middle stabilizing cable, the lower wind-resistant cable, and the lateral connecting cable, respectively.

[0010] A further technical solution is that the Y-shaped connector includes two connectors I, one connector II, one connector III, two upper connecting rods, and one lower connecting rod. Connector II is connected to the two upper connecting rods and the lower connecting rod respectively. The upper connecting rod is connected to the upper load-bearing cable through connector I. The lower connecting rod is connected to the lower wind-resistant cable and the transverse connecting cable through connector III. Connector II is connected to the middle stabilizing cable.

[0011] A further technical solution is that connector I is threaded to the upper end of the upper connecting rod, connector III is threaded to the lower end of the lower connecting rod, and connector II is connected to the two upper connecting rods and the lower connecting rod respectively by cable clamps and bolts.

[0012] A further technical solution is that the left longitudinal column and the steel crossbeam are connected by a channel plate.

[0013] A further technical solution is that the ends of the upper load-bearing cable, the middle stabilizing cable, the lower wind-resistant cable, and the transverse connecting cable are all provided with cable heads.

[0014] A further technical solution is that the steel crossbeam is provided with several cable end plates, and the upper load-bearing cable and the middle stabilizing cable are both connected to the cable end plates on the steel crossbeam through cable heads.

[0015] A further technical solution is that both the left and right longitudinal columns are equipped with clamps, and the left and right ends of the lower wind-resistant cable are connected to the clamps on the left and right longitudinal columns respectively through cable heads.

[0016] A further technical solution is that the top of both the upper and lower transverse columns is provided with a longitudinal cable end plate, and the two ends of the transverse connecting cable are respectively connected to the longitudinal cable end plates on the top of the upper and lower transverse columns through the cable head.

[0017] The core principle of this invention lies in the Y-shaped connector that links five cables into a whole. Through the rational distribution and coordinated operation of the upper load-bearing cable, the middle stabilizing cable, and the lower wind-resistant cable, the overall stress on the support structure is more evenly distributed, significantly improving its overall stability and wind resistance. It is highly adaptable and particularly suitable for use in areas with high wind loads. Simultaneously, the transverse connecting cables connect multiple photovoltaic modules into a photovoltaic array, forming a stable cable net structure, further enhancing the support structure's wind resistance and torsional deformation resistance, improving its overall stability, and ensuring coordinated deformation of the multiple photovoltaic modules.

[0018] The present invention has the following beneficial effects: The present invention effectively solves the problems of poor stability, insufficient wind resistance and low component safety of existing flexible photovoltaic brackets, and significantly improves the applicability, reliability and economy of photovoltaic brackets. It is particularly suitable for large-scale photovoltaic power generation systems in complex terrain and high wind load areas. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0038] like Figures 1-14 As shown, the present invention provides a novel flexible photovoltaic support structure, including a support structure, a cable structure, and a Y-shaped connector 8.

[0039] The support structure includes several longitudinally arranged left longitudinal columns 201, several longitudinally arranged right longitudinal columns 202, several transversely arranged upper transverse columns 401, and several transversely arranged lower transverse columns 402. The left longitudinal columns 201 and the right longitudinal columns 202 are each provided with steel beams 3, and the two steel beams 3 are arranged in parallel to each other.

[0040] The left longitudinal column 201 and the right longitudinal column 202 are symmetrically distributed in the left and right longitudinal directions, and the upper transverse column 401 and the lower transverse column 402 are symmetrically distributed in the upper and lower transverse directions.

[0041] The cable structure includes an upper load-bearing cable 5, a middle stabilizing cable 6, a lower wind-resistant cable 7, and a transverse connecting cable 9;

[0042] The upper load-bearing cable 5 is connected to two steel crossbeams 3 at both ends, and the photovoltaic panel is set on the upper load-bearing cable 5 to support and fix the photovoltaic panel 1.

[0043] The two ends of the central stabilizing cable 6 are connected to the two steel crossbeams 3 respectively and are located below the upper load-bearing cable 5. It is used to balance the force on the support and reduce structural deformation and vibration.

[0044] The lower wind-resistant cable 7 is connected at both ends to the left longitudinal column 201 and the right longitudinal column 202 respectively and is located below the middle stabilizing cable 6. It is used to enhance the wind resistance of the support and effectively reduce the impact of wind on the support.

[0045] The two ends of the transverse connecting cable 9 are connected to the upper transverse column 401 and the lower transverse column 402 respectively and are located below the lower wind-resistant cable 7 to form a cable net structure, which further enhances the wind resistance and torsional deformation resistance of the support, improves the overall stability of the support, and ensures the coordinated deformation of multiple photovoltaic modules.

[0046] The Y-shaped connector 8 is connected to the upper load-bearing cable 5, the middle stabilizing cable 6, the lower wind-resistant cable 7, and the transverse connecting cable 9 respectively, so as to connect the above five cable structures into a whole; the Y-shaped connector 8 is geometrically optimized and can provide multi-point support, enhancing the wind resistance stability and torsional deformation resistance of the support.

[0047] In this invention, the Y-shaped connector 8 connects five cables into a whole. Through the rational distribution and coordinated operation of the upper load-bearing cable 5, the middle stabilizing cable 6, and the lower wind-resistant cable 7, the overall stress on the support structure is more even, significantly improving its overall stability and wind resistance. This makes it highly adaptable, especially suitable for use in areas with high wind loads. Simultaneously, the transverse connecting cables 9 connect multiple photovoltaic panel modules into a photovoltaic array, forming a stable cable net structure. This further enhances the wind resistance and torsional deformation resistance of the support structure, improving its overall stability and ensuring coordinated deformation of the multiple photovoltaic modules.

[0048] Under wind pressure conditions, the load-bearing cable carries the load and drives the stabilizing cable and the lateral connecting cable to work together through the Y-shaped connector 8; under wind suction conditions, the load-bearing cable carries the load and drives the wind-resistant cable and the lateral connecting cable to work together through the Y-shaped connector 8.

[0049] Therefore, this novel flexible photovoltaic support system is suitable for areas with high wind loads, especially in high wind speed environments. It can effectively reduce the torsional deformation of the flexible photovoltaic support structure caused by wind, enhancing the safety and stability of the system. Whether in complex terrain or extreme weather conditions, this support system can provide durable and reliable support for photovoltaic arrays, making it suitable for the construction of large-scale photovoltaic power generation systems.

[0050] like Figure 5 As shown, in this embodiment, the Y-shaped connector 8 includes two connectors I 14, one connector II 15, one connector III 16, two upper connecting rods, and one lower connecting rod. Connector II 15 is connected to the two upper connecting rods and the lower connecting rod respectively. The upper connecting rod is connected to the upper load-bearing cable 5 through connector I 14, providing stable support for the photovoltaic panel 1 and ensuring the stability of the photovoltaic panel under wind force and its own weight. The lower connecting rod is connected to the lower wind-resistant cable 7 and the transverse connecting cable 9 through connector III 16, further enhancing the structure's wind resistance and torsional resistance, and improving overall stability. Connector II 15 is connected to the middle stabilizing cable 6, ensuring that the support maintains geometric stability under stress and reducing structural deformation and vibration.

[0051] The structures of connector I14, connector II15, and connector III16 are as follows: Figures 8-10 As shown.

[0052] In this embodiment, for ease of connection, the ends of the two upper connecting rods and the lower connecting rod are provided with external threads, and the connecting parts I 14 and III 16 are provided with internal threads and connected to the connecting rods through the threads; the connecting part II 15 is connected to the connecting rods through bolts and cable clamps.

[0053] like Figure 6 As shown, in this embodiment, the left longitudinal column 2 and the steel beam 3 are connected by a channel plate 13.

[0054] In this embodiment, the connection between the cable structure and the support structure is as follows: the ends of the upper load-bearing cable 5, the middle stabilizing cable 6, the lower wind-resistant cable 7, and the transverse connecting cable 9 are all equipped with cable heads 11. The steel crossbeam 3 is provided with several cable end plates 12, and the upper load-bearing cable 5 and the middle stabilizing cable 6 are connected to the cable end plates 12 on the steel crossbeam 3 via cable heads 11. The left longitudinal column 201 and the right longitudinal column 202 are both equipped with clamps 10, and the left and right ends of the lower wind-resistant cable 7 are respectively connected to the clamps 10 on the left longitudinal column 201 and the right longitudinal column 202 via cable heads 11. The tops of the upper transverse column 401 and the lower transverse column 402 are both equipped with longitudinal cable end plates 12, and the two ends of the transverse connecting cable 9 are respectively connected to the longitudinal cable end plates 12 on the tops of the upper transverse column 401 and the lower transverse column 402 via cable heads 11.
