Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic support system. Background Technology

[0002] Among related technologies, long-span photovoltaic (PV) support systems can save materials, reduce the number of supporting structures, lower costs and installation time, and have the advantages of high flexibility and adaptability to irregular terrain. However, long-span PV support systems have high requirements for the structural strength of the PV support, requiring the use of more robust materials or optimized designs. At the same time, wind and earthquake resistance designs are complex. The larger the span, the greater the risk of deformation under wind loads and earthquakes. Furthermore, in some existing technologies, the PV support system has a low clearance height. The special environment of tidal flats and sea areas forces the PV support system to withstand loads such as wind, snow, waves, and even sea ice, as well as corrosion damage from high humidity and high salt. In addition, the anchors at both ends of the stabilizing cables of the PV support system are located at the bottom of the column. Changes in seawater level have a strong corrosive effect on the stabilizing cables and anchors of long-span flexible supports. Therefore, the application scenarios of long-span PV support systems are limited. Utility Model Content

[0038] The following is for reference. Figures 1-5 A photovoltaic support system 1 according to an embodiment of the present utility model is described.

[0039] like Figures 1-5 As shown, the photovoltaic support system 1 according to this utility model includes: a first base 10, a first cable 30, a second base 20, a second cable 40, a third cable 50, and a support member 60. The first base 10 is configured as two spaced apart. The two ends of the first cable 30 are connected between the two first bases 10, and the first cable 30 is adapted to mount the photovoltaic module 2. The second base 20 is disposed between the two first bases 10. The two ends of the second cable 40 are adapted to connect to the two first bases 10 respectively or to connect the first base 10 and the second base 20 respectively. The two ends of the third cable 50 are adapted to connect to the two first bases 10 respectively or to connect the first base 10 and the second base 20 respectively. The support member 60 is connected to the first cable 30, the second cable 40, and the third cable 50 respectively, and the support member 60 tensions the second cable 40 and the third cable 50 in a direction away from each other.

[0040] Specifically, the first base 10 and the second base 20 constitute the base structure of the photovoltaic support system 1. The first cable 30, the second cable 40, and the third cable 50 can be installed on the base structure. The large-span photovoltaic support system 1 is prone to lateral displacement or torsion under wind loads or earthquakes. The cables can form a prestressed structure through tension, effectively resisting lateral forces, enhancing the stability, deformation resistance, and load-bearing capacity of the photovoltaic support system 1, and reducing the risk of swaying or overturning. Furthermore, the large-span photovoltaic support system 1 may sag and deform under its own weight or snow accumulation. The first cable 30, the second cable 40, and the third cable 50 distribute the load through upward or oblique tension, reducing the bending stress of the support member 60, avoiding excessive deformation. Moreover, the cables are connected to multiple support members 60, which can enhance the overall structural rigidity, prevent local instability, and absorb and disperse energy during wind vibration or equipment vibration, reducing structural fatigue damage and extending service life.

[0041] Here, the first cable 30 is connected to two first bases 10 respectively, the second cable 40 can be connected to either the first base 10 or the second base 20, and the third cable 50 can also be connected to either the first base 10 or the second base 20. The first cable 30 is used to mount the photovoltaic module 2. During installation, the levelness or tilt angle of the photovoltaic support system 1 can be corrected by adjusting the tension of the first cable 30 to ensure the installation accuracy of the photovoltaic module 2. The first cable 30, the second cable 40, and the third cable 50 are arranged along the span direction of the support, which can prevent the overall structure of the photovoltaic support system 1 from swinging along the span direction of the support, thereby improving the stability and load-bearing capacity of the overall structure of the photovoltaic support system 1. The support member 60 can be set between two second bases 20 or between adjacent first bases 10 and second bases 20. The support member 60 is connected to the first cable 30, the second cable 40 and the third cable 50 respectively, and the support member 60 can tension the second cable 40 and the third cable 50 respectively to increase the net height under the photovoltaic support system 1, making the photovoltaic support system 1 applicable to more scenarios.

[0042] The photovoltaic support system 1 of this utility model adopts a three-cable structure system of first cable 30, second cable 40 and third cable 50, which can improve the overall structural stability and load-bearing capacity of the photovoltaic support system 1, improve safety in use, support large span of the photovoltaic support system 1, and increase the net height of the photovoltaic support system 1, making the photovoltaic support system 1 applicable to more scenarios.

[0043] According to some embodiments of this utility model, such as Figure 3 As shown, the second cable 40 and the third cable 50 are tensioned away from each other in the height direction to increase the clearance height under the photovoltaic support system 1, making the photovoltaic support system 1 applicable to more scenarios.

[0044] According to some embodiments of this utility model, such as Figure 3 As shown, the highest point of the second cable 40 is not higher than the lowest point of the first cable 30, so as to avoid affecting the overall structural stability of the photovoltaic support system 1.

[0045] According to some embodiments of this utility model, such as Figure 3 As shown, the two ends of the second cable 40 are lower than the two ends of the third cable 50 in the height direction. In some embodiments, the second cable 40 is arched, with its highest point coinciding with or slightly lower than the lowest point of the first cable 30, and its two ends are fixed to the support member 60, with the height of the fixing point lower than the fixing points at both ends of the third cable 50, but not lower than the lowest point of the maximum displacement of the third cable 50.

[0046] According to some embodiments of this utility model, such as Figure 1 As shown, the first cable 30 is constructed as a plurality of spaced-apart cables. The plurality of first cables 30 are respectively connected to the support member 60 and are respectively adapted to be connected to the photovoltaic module 2. Two adjacent first cables 30 can be used to support one photovoltaic module 2, which can improve the support stability of the photovoltaic module 2.

[0047] In some embodiments, the support member 60 may be constructed in the shape of a triangle, quadrilateral, square pyramid, tetrahedron, etc.

[0048] According to some embodiments of the present invention, the support member 60 includes a first support portion 61, a second support portion 62, and a support rod 63. A plurality of first cables 30 are spaced apart on the first support portion 61. The second support portion 62 is spaced apart from the first support portion 61 in the height direction and is connected to a third cable 50. Both ends of the support rod 63 are respectively connected to the first support portion 61 and the second support portion 62 to maintain the distance between the first support portion 61 and the second support portion 62. At least one of the multiple support members 60 has its first support portion 61 connected to a second cable 40. Specifically, refer to... Figure 4 At the support member 60, the first cable 30, the second cable 40, and the third cable 50 can be arranged in layers along the height direction under the action of the first support part 61, the second support part 62, and the support rod 63. Among them, multiple first cables 30 are located at the top of the first support part 61, the third cables 50 are located at the bottom of the second support part 62, and the second cable 40 is located between the first support part 61 and the second support part 62. In some embodiments, the second cable 40 can be connected to the first support part 61 of at least one of the multiple support members 60. Since the first support part 61 is located at the top, the connection of the second cable 40 to one of the first support parts 61 can increase the clearance height below the photovoltaic support system 1.

[0049] In some embodiments, the support member 60 has multiple members. In the first support member, its overall height is relatively low, and the second cable 40 is fixed to the top of the second support portion 62 in the height direction. In the second support member, its overall height is relatively high compared to the first support member, and the second cable 40 is fixed to the middle portion of the second support portion 62 in the height direction. In the third support member, its overall height is relatively high compared to the second support member, and the second cable 40 is fixed to the top of the second support portion 62 in the height direction. In the fourth support member, its overall height is relatively high compared to the third support member, and the second cable 40 is fixed to the top of the second support portion 62 in the height direction.

[0050] According to some embodiments of the present invention, at least one of the plurality of support members 60 further includes a third support portion 64. The third support portion 64 is disposed between the first support portion 61 and the second support portion 62 and is connected to the plurality of support rods 63 respectively. The third support portion 64 is also connected to the second cable 40. Specifically, as shown... Figure 4 As shown, the third support 64 is connected to multiple support rods 63 to enhance the overall structural rigidity and improve the load-bearing capacity of the multiple support rods 63 in the width direction of the photovoltaic support system 1. In some embodiments, the second cable 40 is located between the first support 61 and the second support 62 and is disposed in the third support 64 of at least one of the multiple support members 60.

[0051] According to some embodiments of this utility model, such as Figure 1 As shown, the first base 10 and the second base 20 are configured as multiple sets spaced apart in the width direction. Each set of the first base 10 and the second base 20 is provided with a first cable 30, a second cable 40, and a third cable 50; the support members 60 between adjacent sets are connected to each other. Here, the two first bases 10, the two second bases 20, and the multiple cables together form a row of flexible photovoltaic supports in the span direction. The first bases 10 and the second base 20 are configured as multiple sets spaced apart in the width direction, so that the multiple rows of flexible photovoltaic supports are spaced apart in the width direction, and the support members 60 of adjacent flexible photovoltaic supports are connected to each other.

[0052] According to some embodiments of this utility model, such as Figure 4As shown, the photovoltaic support system 1 also includes a first connecting rod 71 and a second connecting rod 72. The first connecting rod 71 extends in the width direction and connects two adjacent sets of second support parts 62 to each other. One end of the second connecting rod 72 is connected to an adjacent set of second support parts 62, and the other end of the second connecting rod 72 is connected to an adjacent set of first support parts 61. Specifically, two adjacent sets of support members 60 in the width direction are connected by the first connecting rod 71 and the second connecting rod 72. The first connecting rod 71 connects two adjacent sets of second support parts 62 to each other, and the second connecting rod 72 connects an adjacent set of second support parts 62 to an adjacent set of first support parts 61, thereby forming a stable spatial system, enhancing the overall structural rigidity, and preventing local instability.

[0053] According to some embodiments of this utility model, such as Figure 4 As shown, the photovoltaic support system 1 also includes a third connecting rod 73. One end of the third connecting rod 73 is connected to the first support part 61 of the adjacent group, and the other end of the third connecting rod 73 is connected to the second connecting rod 72. The third connecting rod 73 is designed to connect the first support part 61 and the second connecting rod 72 of the adjacent group in order to further stabilize the overall structure of the photovoltaic support system 1 and enhance the overall structural rigidity.

[0054] According to some embodiments of this utility model, such as Figure 5 As shown, the second base 20 is constructed in two parts; the photovoltaic support system 1 also includes a wind-resistant base 80 and a wind-resistant cable 90. The wind-resistant base 80 is set on the ground and located between the two second bases 20; the wind-resistant cable 90 connects at least one support member 60 to the wind-resistant base 80. Here, the wind-resistant base 80 can be fixed to the ground, and the wind-resistant cable 90 can be set perpendicular to the span direction to resist lateral winds and prevent the photovoltaic support system 1 from tilting laterally. The wind-resistant cable 90 is connected to both the support member 60 and the wind-resistant base 80 to constrain the position of the support member 60 relative to the ground under wind load or seismic action, preventing the structure of the photovoltaic support system 1 from being damaged, improving the load-bearing capacity of the photovoltaic support system 1, and thus improving the structural stability of the photovoltaic support system 1.

[0055] The wind-resistant base 80 can be constructed as one. When the wind-resistant base 80 is one, the entire photovoltaic support system 1 uses a single wind-resistant cable 90, and the wind-resistant cable 90 is connected to different support members 60 that are spaced apart in the span direction.

[0056] The wind-resistant base 80 can also be constructed in multiple ways, according to some embodiments of this utility model, such as Figure 1As shown, the support member 60 is constructed as a plurality of spaced-apart members arranged on the first cable 30. There are multiple wind-resistant bases 80, each positioned between two adjacent support members 60. The wind-resistant base 80 is connected to the two adjacent support members 60 via a wind-resistant cable 90. In some embodiments, two second bases 20 are arranged between two first bases 10, and multiple wind-resistant bases 80 are arranged between the two second bases 20. One wind-resistant base 80 is positioned between two adjacent support members 60. In this case, one wind-resistant base 80 is connected to the corresponding two support members 60 via a wind-resistant cable 90, so that during wind loads or earthquakes, the two support members 60 are pulled together, further improving the load-bearing capacity of the photovoltaic support system 1.

[0057] In some embodiments, multiple wind-resistant bases 80 are distributed on both sides of the photovoltaic support system 1 in the span direction.

[0058] According to some embodiments of this utility model, such as Figure 5 As shown, the wind-resistant base 80 includes a base body 81, a first swing arm 82, and a second swing arm 83. A first hinge portion and a second hinge portion are formed on the base body 81. The first swing arm 82 and the second swing arm 83 are respectively hinged to the first hinge portion and the second hinge portion. The first swing arm 82 is provided with a first winding portion 85 suitable for the wind-resistant cable 90 to pass through, and the second swing arm 83 is provided with a second winding portion 86 suitable for the wind-resistant cable 90 to pass through. Specifically, the first swing arm 82 is adapted to be rotatably connected to the base body 81 via the first hinge portion, and the second swing arm 83 is adapted to be rotatably connected to the base body 81 via the second hinge portion. The wind-resistant cable 90 can pass through the first winding portion 85 of the first swing arm 82 and the second winding portion 86 of the second swing arm 83, respectively.

[0059] Here, after the wind-resistant cable 90 is assembled with the support member 60, the wind-resistant cable 90 is in a critically taut state, preventing any loosening. This not only improves aesthetics but also facilitates daily inspections, avoiding potential safety hazards. It ensures the required stroke of the wind-resistant cable 90 when the photovoltaic support system 1 is subjected to wind-driven forces, eliminating the need for further dimensional verification. Under normal circumstances, the wind-resistant cable 90 does not exert any restraining force. Only when the support member 60 is stressed and pulls the wind-resistant cable 90 beyond a preset limit will the wind-resistant cable 90 exert a restraining force, eliminating the need for additional reinforcement of the wind-resistant cable 90 structure. The connection method between the wind-resistant cable 90 and the wind-resistant base 80 proposed in this invention does not transfer the additional internal force generated by the displacement of the support member 60 to the wind-resistant base 80, which is beneficial to the overall structural and installation stability of the photovoltaic support system 1.

[0060] According to some embodiments of this utility model, such as Figure 5As shown, the wind-resistant base 80 also includes a limiting part 84. The limiting part 84 is disposed on the base body 81 and located between the first hinge part and the second hinge part, and is suitable for the wind-resistant cable 90 to pass through. The limiting part 84 can limit the position of the wind-resistant cable 90 relative to the base body 81, thereby limiting the position of the wind-resistant cable 90 relative to the bottom surface. The wind-resistant cable 90 passes through the first winding part 85, the limiting part 84 and the second winding part 86 in sequence. At this time, one wind-resistant base 80 and the corresponding two support members 60 are connected by the same wind-resistant cable 90. The first swing arm 82, the second swing arm 83 and the wind-resistant cable 90 form a "W" shaped arrangement structure, which can reduce the number of wind-resistant cable 90 foundations used.

[0061] In some embodiments, a limiting part 84 is provided on the base body 81 for fixing the wind-resistant cable 90. The first swing arm 82 and the second swing arm 83 are mounted on the base body 81 and can rotate around the hinge point of the base body 81. The limiting part 84 provided on the base body 81 can limit the downward rotation angle of the first swing arm 82 and the second swing arm 83. When assembling the wind-resistant cable 90 with the support member 60, it is not necessary to accurately measure the length of the wind-resistant cable 90. It is only necessary to ensure that the first swing arm 82 and the second swing arm 83 are in the lowest rotatable position. This design makes the assembly operation convenient and reduces the possibility of misassembly. Furthermore, when fixing the wind-resistant cable 90, the first swing arm 82 and the second swing arm 83 are in the lowest rotatable position. Straightening the wind-resistant cable 90 ensures the required stroke of the wind-resistant cable 90 when the photovoltaic support system 1 is subjected to wind-blown action.

[0062] Furthermore, when the diameter of the wind-resistant cable 90 is too large to be straightened by the weight of the first swing arm 82 and the second swing arm 83, the weight of the swing arm can be increased, or a heavy object can be suspended on the first swing arm 82 and the second swing arm 83, or a position can be set on the wind-resistant cable 90 and a heavy block can be suspended.
