Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic brackets, and in particular to a flexible photovoltaic bracket system. Background Art

[0002] With the continuous development of photovoltaic power station projects in the "fish-light complementary" model in coastal areas, the application of flexible photovoltaic brackets in "fish-light complementary" projects is also increasing. Faced with the environmental status of large wind loads in coastal areas, the problem that flexible photovoltaic brackets urgently need to solve is to improve the anti-torsion performance and wind suction resistance. The traditional three-cable flexible photovoltaic bracket has two horizontal cables above and one load-bearing cable below, presenting an inverted triangle shape and poor anti-torsion performance. And its deflection under wind pressure can be controlled by the load-bearing cable, but the deflection under wind suction is completely controlled by increasing the initial tension of the horizontal cable. Excessive initial tension also places higher requirements on the anchoring structure, which is not conducive to structural safety and cost-effectiveness.

[0003] Although the common wind-resistant cable forms and setting positions can solve the wind resistance problem of the three-cable flexible photovoltaic bracket, in the actual project implementation process, the setting of the wind-resistant cables often occupies the lower space of the flexible photovoltaic bracket, causing inconvenience to fishery production and violating the original intention of the application of the flexible photovoltaic bracket. Utility Model Content

[0004] The purpose of the present application is to provide a flexible photovoltaic support system to solve the problems of excessive vertical overall deformation, large shaking and poor structural stability of photovoltaic supports in strong wind environments in the prior art.

[0012] In a further solution, a transverse connecting structure is further connected between two adjacent brace structures, and the transverse connecting structure includes an upper oblique rod, a lower horizontal rod and a middle oblique rod;

[0013] The upper oblique rod connects the connection points of two adjacent strut structures and the corresponding horizontal cables; the lower horizontal rod connects the connection points of two adjacent strut structures and the corresponding load-bearing cables, and the middle oblique rod obliquely connects the two adjacent strut structures.

[0014] According to a further solution of the present application, the outermost pipe piles are provided with an anchoring structure, wherein the anchoring structure comprises an inclined cable and an anchor pile, wherein one end of the inclined cable is connected to the anchor pile, and the other end is connected to the horizontal cable.

[0020] In this application, considering the high wind pressure in coastal areas, anti-wind suction cables are added to effectively suppress the deformation of the bracket under the action of wind suction and ensure the safety of solar photovoltaic panels.

[0021] In this application, the lowest point of the wind-resistant suction cable installation is set above the lowest point of the load-bearing cable, which retains the clearance of the lower flexible bracket and the unobstructed north-south direction, which is of great significance for the implementation of photovoltaic power stations, especially photovoltaic power stations using flexible bracket structures, and fishery farming in fish-light projects.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Embodiment 1

[0030] like Figure 1 and Figure 2 As shown, this embodiment discloses a flexible photovoltaic support system, which includes: multiple groups of flexible photovoltaic support units arranged in parallel. In this embodiment, 5 groups of flexible photovoltaic support units are arranged. In other embodiments, their number can be increased or decreased according to the actual project construction requirements.

[0031] Each group of flexible photovoltaic support units includes multiple pipe piles 1, and the number of pipe piles 1 is determined by the span number of the entire flexible photovoltaic support unit. Normally, multiple pipe piles 1 are distributed at both ends and the middle of the flexible photovoltaic support unit; multiple groups of parallel flexible photovoltaic support units are interconnected by pile top crossbeams 6. Normally, the pile top crossbeams 6 are arranged at the top of the pipe piles 1, spanning multiple groups of flexible photovoltaic support units to connect them together; horizontal cables 2 are connected above the pipe piles 1 along the extension direction of the flexible photovoltaic support unit. Normally, each flexible photovoltaic support unit is provided with two groups of parallel horizontal cables 2, which are respectively connected to the pile top crossbeams 6 and are connected to each other through the support rod structure 4. Multiple solar photovoltaic panels 9 are also carried above the horizontal cables 2.

[0032] In the same flexible photovoltaic support unit, a load-bearing cable 3 is arranged under each horizontal cable 2; usually, the load-bearing cables 3 are parabolic in shape, connected to each other and to the horizontal cable 2 through a support rod structure 4; Figure 6 In this embodiment, the support rod structure 4 is square, and its four corners are connected to two horizontal cables 2 and two load-bearing cables 3; the support rod structure 4 here includes four first rods 41 and one second rod 42, and the four rods are connected at the ends to form a quadrilateral structure, which is almost square here. The second rod 42 is installed between two diagonal corners of the quadrilateral. Since the horizontal cable 2 is used to install the solar photovoltaic panel 9, in order to maximize the light reception, its installation has a certain tilt angle, resulting in a first rod 41 at the upper part having a certain tilt angle. This embodiment provides What is provided is a quadrilateral structure. In actual application, hexagons, octagons, etc. can be set. The number of sides of the structure can be reasonably designed according to the number of groups of horizontal cables 2 and load-bearing cables 3. Secondly, a lock of suitable size is installed on the first rod 41. Here is an example, the lock includes a U-shaped locking rod and a lock body, two through holes are provided on the lock body, and external threads are provided at both ends of the U-shaped locking rod. The lock body is welded and fixed to the connection point of the support structure 4, and the two ends of the U-shaped locking rod are inserted into the through holes on the lock body and locked by nuts. At this time, the horizontal cable 2 or the load-bearing cable 3 is firmly fixed by the U-shaped locking rod.

[0033] The support rod structure 4 of this embodiment can greatly enhance the stability of the cable system while transmitting internal forces, which is conducive to the realization of a larger structural span. The load-bearing cables 3 and the horizontal cables 2 jointly bear the dead weight of the solar photovoltaic panels and have the function of resisting snow loads and wind pressure loads.

[0034] Among them, continuing to observe the attached figure, the flexible photovoltaic bracket unit also includes a plurality of wind-resistant suction ropes 5, one end of the wind-resistant suction rope 5 is connected to the pipe pile 1, and ensures that the connection point is not lower than the lowest point of the load-bearing rope 3, and the middle part of the two horizontal ropes 2 of each group of flexible photovoltaic bracket units is connected with a connecting piece, and the other end of the wind-resistant suction rope 5 is fixedly connected to the connecting piece; two adjacent wind-resistant suction ropes 5 are arranged in an inverted "V" shape.

[0035] The wind-resistant suction cable 5 provided in this embodiment can effectively suppress the deflection of the flexible bracket under wind suction while ensuring the clearance of the lower flexible bracket and the smoothness in the north-south direction, thereby improving the safety of the solar photovoltaic panel. Embodiment 2

[0036] Reference Figure 4 and 5 In this embodiment, a cost-effective transverse connecting structure 7 is provided, which is made of less materials, has a simple design, and has a greater auxiliary capacity for the stability of the entire bracket. The connecting structure 7 is arranged between the strut structures 4 corresponding to two adjacent groups of flexible photovoltaic bracket units, and is used to connect the two groups of flexible photovoltaic bracket units; usually, the transverse connecting structure 7 includes an upper oblique rod 71, a lower horizontal rod 72 and a middle oblique rod 73, but is not limited to this. In other embodiments, the transverse connecting structure 7 can be increased or decreased according to actual needs; the upper oblique rod 71 is arranged at the connection node between the strut structure 4 and the horizontal cable 2 corresponding to two adjacent groups of flexible photovoltaic bracket units; the lower horizontal rod 72 is arranged at the connection node between the strut structure 4 and the load-bearing cable 3 corresponding to two adjacent groups of flexible photovoltaic bracket units; one end of the middle oblique rod 73 is connected to the connection node between the strut structure 4 and the horizontal cable 2 corresponding to one of the flexible photovoltaic bracket units, and the other end is connected to the connection node between the strut structure 4 and the load-bearing cable 3 corresponding to another adjacent flexible photovoltaic bracket unit; wherein, the middle oblique rod 73 has the function of reinforcing ribs to improve the stability of the structure. The transverse connection structure 7 provided in this embodiment can enhance the ability of the structure to resist torsional deformation and can effectively maintain the out-of-plane stability performance of the horizontal cable 2 .

[0037] In addition, the outermost pipe pile 1 of this embodiment is provided with an anchoring structure 8, which includes an inclined cable and an anchor pile. One end of the inclined cable is connected to the anchor pile, and the other end is connected to the horizontal cable 2; at this time, the inclined cable connects the connection point of the horizontal cable 2 and the pile top beam.

[0038] After the device is installed and used, when facing strong winds, the square brace structure 4 connects the load-bearing cable 3 and the horizontal cable 2 in each flexible photovoltaic bracket unit, so that the two form a relatively integrated structure with strong wind pressure resistance. Secondly, the two adjacent brace structures 4 are connected by the connecting structure 7, so that the entire bracket structure has a high degree of connection, further improving the wind resistance and stability of the bracket. When facing wind suction, the anti-wind suction cable 5 is used to limit the upward arching effect of the horizontal cable 2, ensuring that the deformation of the structure under wind suction meets safety requirements. On the other hand, the lowest point of the anti-wind suction cable is not lower than the lowest point of the load-bearing cable, which can ensure that there is enough space at the bottom of the photovoltaic bracket to ensure normal fishery production.
