Technical Field
[0001] The utility model belongs to the technical field of photovoltaic supports and relates to a flexible support end column which is adaptable to terrain. Background Art
[0002] As global energy issues become increasingly serious, solar energy, as a renewable green energy source, is gaining increasing attention in my country, leading to the rapid construction of photovoltaic power stations. Because the fixed supports used in traditional ground-based power stations are subject to numerous site conditions, flexible photovoltaic supports with large spans have become more widely used in recent years.
[0003] Flexible photovoltaic supports are characterized by their adaptability to complex terrain, strong site adaptability, and a small footprint. They primarily rely on steel strands to support photovoltaic modules, so the safety and stability of the strands during use are crucial.
[0004] Currently, due to the undulating terrain of mountain photovoltaic projects, the steel strands are prone to excessive bending when anchored at the ends of the end columns. At this time, under the action of wind loads, the steel strands are more likely to be damaged or broken, posing a huge safety hazard to the entire flexible photovoltaic system. Summary of the Invention

[0009] Furthermore, the fixing device includes two support frames arranged at an interval, a channel is formed between the two support frames, and each support frame is provided with a mounting hole for mounting a rotation pin.
[0010] Furthermore, the support frame includes an end anchor plate and two limit members connected to each other, and the end anchor plate and the limit members are both provided with a semicircular arc groove for combining to form a mounting hole.
[0011] Furthermore, the limiting member includes a limiting portion and a fixing portion connected to each other;
[0012] The limiting portion is located outside the channel to limit the swing of the portion of the steel strand located outside the channel;
[0013] The fixing portion is detachably connected to the end anchor plate.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments. Instead, it should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. After reading the contents of the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.
[0025] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings.
[0026] The embodiment of the present invention provides a flexible support end column that adapts to the terrain, such as Figure 1 and Figure 2 As shown, the pin 8 and a fixture 14 are fixed to the end of the end column. The fixture 14 has a channel 11 formed therein for the passage of the steel strand at the end of the end column. The fixture 14 is also provided with a mounting hole 12, which allows the pin 8 to be rotatably mounted on the fixture 14. The pin 8 also includes a middle section positioned within the channel 11, which has a through hole for the steel strand to pass through.
[0027] The steel strand passes through the channel 11 formed by the fixing device 14 and the through hole of the pin 8 and then rotates freely at the end of the end column, thereby avoiding excessive bending of the steel strand when anchored at the end of the end column.
[0028] Specifically, such as Figure 3 As shown, the fixing device 14 includes two support brackets 15 spaced apart at the ends of the end column, forming a channel 11 between the two support brackets 15, and each support bracket 15 is provided with a mounting hole 12 for the rotation of the pin 8. Through the mounting hole 12, the pin 8 can rotate freely on the support bracket 15.
[0029] Furthermore, Figure 1 As shown, support frame 14 includes connected end anchor plates 9 and two stoppers 7. Semicircular slots are formed in the end anchor plates 9 and opposite the stoppers 7. The combination of the two forms a mounting hole 12 for the pin 8 to pass through. The stoppers 7 and end anchor plates 9 secure the pin 8 within the mounting hole 12, ensuring that the pin 8 remains stable and prevents it from deviating from the slot even in complex terrain or extreme wind conditions.
[0030] like Figure 4As shown, the limiting member 7 includes a limiting portion 72 and a fixing portion 71 that are connected to each other. The limiting portion 72 is located outside the channel 11 for the steel strand to pass through. The end of the limiting portion 72 away from the channel 11 has a certain extension along the direction of the steel strand. The limiting portion 72 can effectively limit the swing amplitude of part of the steel strand outside the channel 11.
[0031] The fixing portion 71 is detachably connected to the end anchor plate 9, as shown in FIG. Figure 5 As shown, each end anchor plate 9 further includes a fixing portion 91 located outside the channel 11. Fixing holes 13 for bolt connection are correspondingly formed in the fixing portion 71 of the stopper 7 and the fixing portion 91 of the end anchor plate 9. Bolts passing through the fixing holes 13 effectively secure the stopper 7 to the end anchor plate 9, preventing the pin 8 from disengaging from the mounting hole 12. The bolted connection further simplifies assembly and disassembly of the stopper 7 and the end anchor plate 9.
[0032] The pin 8 includes a middle section located in the channel 11 and other sections outside the channel 11. The middle section of the pin includes at least one plane, which is used to be in close contact with the steel strand anchor. Specifically, the other sections outside the channel 11 are cylinders, and the middle section in the channel 11 is a rectangular parallelepiped. The middle section of the pin 8 is provided with a through hole for the steel strand to pass through. One of the planes of the middle section rectangular parallelepiped is used to be in close contact with the steel strand anchor. The special structure of the pin 8 in this embodiment ensures that the steel strand can rotate freely in the arc groove formed between the limit member 7 and the end anchor plate 9, and realizes that the flexible bracket steel strand can adapt to the terrain when anchored at the end, and is anchored straight without bending.
[0033] In order to ensure that the end anchor plate 8 can be firmly positioned above the end of the end column and not easily tilted, the end column anchor plate 9 of this embodiment is fixed on the end column top plate 10.
[0034] In addition, the lower end structure of the end column top plate 10 in this embodiment is as follows: Figure 1 As shown, it also includes an end column base plate 1, an end column square steel tube 3, an end column stiffening rib 2, a first end column ear plate 4, a second end column ear plate 5, and a third end column ear plate 6. The end column square steel tube 3 is fixed directly above the end column base plate 1, and the end column stiffening ribs 2 are fixed to the four sides of the end column square steel tube 3, with the bottom abutting against the end column base plate 1. The end column stiffening ribs 2 enhance the bending strength of the end column, making the flexible bracket more reliably anchored at the end. The first end column ear plate 4, the second end column ear plate 5, and the third end column ear plate 6 are each provided with openings for connecting other flexible bracket end columns, other flexible bracket windproof cables, and other flexible bracket end pull rods.
[0035] The installation method of this embodiment is as follows: First, the flexible support end column is connected in sequence by connecting the end column base plate 1, end column square steel tube 3, end column top plate 10, and end anchor plate 9. The first end column ear plate 4, second end column ear plate 5, and third end column ear plate 6 are connected to the other end components of the flexible support. After all parts are firmly connected, the pin 8 is installed between the limiter 7 and the end anchor plate 9. The fixing portion 71 of the limiter 7 is fixed to the fixing portion 91 of the end anchor plate 9 with bolts. Finally, the flexible support steel strand is tensioned and anchored, and the direction of the steel strand is adjusted.
