Generally, the terms "comprise" and "include" only indicate the inclusion of the steps and elements explicitly identified, and these steps and elements do not constitute an exclusive list, and the method or device can also include other steps or elements. The element defined by the phrase "comprising a" does not exclude the presence of additional identical elements in the process, method, product or device comprising the element.

In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.
[0036] As shown in Figure 1 The post 03 includes a post plate 031, an ear plate 032 and a pin shaft 2033, and the post plate 031 and the ear plate 032 are independent parts relative to the column 5. In the prior art, additional parts are added to the column 5 to realize the connection of the main cable 104 and the cable-stayed assembly 902 with the column 5 through the pin shaft 2033.
[0037] Referring to Figures 2-5 Some embodiments of the present application disclose a post 10, which has the functions of connecting the column 5, the main cable 1 and the cable-stayed assembly 9, and adjusting the main cable 1 and the cable-stayed assembly 9 within a certain angle range.
[0038] The post 10 includes a pin shaft 2, a pin hole 3 and a main cable adjusting hole 4, the pin shaft 2 and the main cable adjusting hole 4 are arranged on the column 5, the pin hole 3 is used for installing the pin shaft 2, the pin hole 3 is arranged through the column 5, and the pin shaft 2 is arranged in the pin hole 3 to realize the installation of the pin shaft 2 on the post 10.
[0039] The pin shaft 2 is exposed to the pin hole 3 at both ends to form an extension section 21, as Figure 3As shown, both ends of the pin 2 protrude from the head 10. The part of the pin 2 that protrudes from the head 10 is the extension section 21 of the pin 2 outside the head 10. The extension section 21 has a locking structure 6. The locking structure 6 is used to limit the pin 2 along its own axis direction to prevent the pin 2 from coming out of the pin hole 3, so as to form a pin node that integrates the pin 2 and the head 10.
[0040] The main cable adjustment hole 4 is set through the column head 10. The pin 2 has a recess 22. A main cable fixing hole 23 adapted to the main cable 1 is opened at the center of the platform of the recess 22. The main cable fixing hole 23 corresponds to and is connected to the main cable adjustment hole 4. After the pin 2 is installed in the pin hole 3, the main cable fixing hole 23 is connected to the main cable adjustment hole 4. After the main cable 1 passes through the main cable adjustment hole 4 and the main cable fixing hole 23, it is fixed by the anchoring structure 7. The anchoring structure 7 abuts against the recess 22. The pitch angle of the main cable 1 can be adjusted in the main cable adjustment hole 4.
[0041] This solution forms a column head 10 on the column 5 by opening a pin hole 3 and a main cable adjustment hole 4 on the column 5, and inserting the pin 2 into the pin hole 3. This eliminates the need to add parts to the column 5 to form a structure for installing the pin 2 and the main cable 1. On the one hand, it reduces the number of parts and lowers the cost of the column head 10. On the other hand, it eliminates the process of assembling the column head 10 and the process of assembling the column head 10 on the column 5, simplifying the assembly process of the end bracket 11 with the column head 10 and improving the assembly efficiency of the end bracket 11.
[0042] The column head 10 is preferably located at the end of the column 5 that is not connected to the ground foundation. Alternatively, the column head 10 may not be located at the end of the column 5 that is not connected to the ground foundation, but rather at a distance from the end, which improves the flexibility of the column head 10 in the column 5.
[0043] This solution creates a column head 10 on the column 5 by opening pin holes 3 and main cable adjustment holes 4 on the column 5. This eliminates the need for connecting the column 5 and the column head 10, ensuring the connection strength between the column 5 and the column head 10 and avoiding the impact of unstable connection structure on the connection strength between the column 5 and the column head 10.
[0044] The column head 10 disclosed in this solution, after having pin holes 3 and main cable adjustment holes 4 in the column 5, has its structure outside the pin holes 3 and main cable adjustment holes 4 serving as the structure of the column head 10. Compared with the prior art, this eliminates components such as the column head plate and ear plate, representing a material-reducing design, which is the opposite of the additive design approach for the column head 10 in related technologies. Although this solution achieves the setting of the column head 10 through a material-reducing design, it does not affect the connection strength between the column head 10 and the column 5, nor is the connection strength between the column head 10 and the column 5 affected by the welding quality; in fact, it improves the connection strength between the column head 10 and the column 5 to a certain extent.
[0045] In some embodiments, the locking structure 6 includes a pin 61 and a socket 62, the socket 62 being formed on the pin 2. By engaging the pin 61 and the socket 62, when the pin 2 is subjected to a force along its own axis, the pin 61 can limit the movement of the pin 2, preventing the pin 2 from sliding out of the pin hole 3.
[0046] Pins 61 and holes 62 are provided at both ends of the pin 2 along its own axis to effectively limit the pin 2 along its own axis.
[0047] The angle between the axis of the socket 62 and the axis of the pin 2 is 80°-95°.
[0048] This solution also discloses another embodiment of the locking structure 6, which includes a retaining ring and an annular groove. The annular groove is formed on the pin 2, and the shape of the annular groove is adapted to the retaining ring. The retaining ring is embedded in the annular groove, and the outer wall of the retaining ring protrudes from the outer wall of the pin 2 to form an annular limiting protrusion on the outer wall of the pin 2. This allows the retaining ring to limit the movement of the pin 2 when the pin 2 is subjected to a force along its own axis, preventing the pin 2 from sliding out of the pin hole 3.
[0049] The preferred connection method between the locking structure 6 and the pin 2 is a detachable connection method to facilitate the installation and removal of the pin 2.
[0050] The anchoring structure 7 includes a wedge anchor 71 and a compression anchor 72. The wedge anchor 71 abuts against the platform of the recess 22, and the contact surface of the wedge anchor 71 is located inside the recess 22 to increase the contact area between the wedge anchor 71 and the platform of the recess, reduce the relative wobble between the wedge anchor 71 and the pin 2, and improve the stability of the fit between the wedge anchor 71 and the pin 2.
[0051] like Figure 4 and Figure 5 As shown, the recessed platform 22 is a groove-shaped structure formed by cutting the outer wall of the pin 2. The platform surface of the recessed platform 22 is the bottom of the groove-shaped structure, and the bottom of the groove is a plane. Optionally, the groove wall of the groove-shaped structure can fit with the side wall of the clamping anchor 71 to increase the contact area between the clamping anchor 71 and the recessed platform 22, thereby limiting the clamping anchor 71 and further improving the stability of the fit between the clamping anchor 71 and the pin 2.
[0052] The compression anchor 72 is located at the end of the main cable 1.
[0053] The main cable adjustment hole 4 is opened through the column head 10, and the main cable adjustment hole 4 has space for adjusting the pitch angle of the main cable 1 along the length direction of the column 5.
[0054] The main cable adjustment hole 4 can be elongated in cross-section along the length of the column 5. The length of the elongated hole is parallel to the length of the column 5 so that the main cable 1 can move along the opening direction to achieve pitch angle adjustment.
[0055] In an embodiment where the cross-section of the main cable adjustment hole 4 along the length of the column 5 is elongated, the cross-section of the main cable adjustment hole 4 can be oblong, rectangular, or other shapes.
[0056] The cross-section of the main cable adjustment hole 4 along the length of the column 5 is not limited to a long strip hole; it can also be circular, polygonal, or irregular in shape.
[0057] In some embodiments, the pin hole 3 and the main cable adjustment hole 4 are cut by at least one of laser cutting, thermal cutting, flame cutting, cold cutting and water cutting. The specific cutting method is selected by those skilled in the art according to actual needs, and no specific limitation is made here.
[0058] By using a cutting process, the pin hole 3 and the main cable adjustment hole 4 can be manufactured, which can improve quality control and production efficiency.
[0059] Because this solution involves creating pin holes 3 and main cable adjustment holes 4 on the column 5 to form a column head 10, the creation of pin holes 3 and main cable adjustment holes 4 will reduce the strength of the column 5 to some extent. During operation, the position where the pin hole 3 of the column 5 mates with the pin shaft 2 bears a relatively large force. The forces of the inclined cable assembly 9 and the main cable 1 are applied to the position where the pin hole 3 is created on the column 5 through the pin shaft 2. To ensure the strength of the position where the pin hole 3 is created on the column head 10, the column head 10 disclosed in this solution also includes a reinforcing plate 8. The reinforcing plate 8 has plate holes 81 corresponding to the position of the pin hole 3. The pin shaft 2 passes through the pin hole 3 and plate holes 81 and is fixed by the locking structure 6.
[0060] Specifically, the reinforcing plate 8 is welded to the column 5 with the pin hole 3 on at least one side to reinforce the column 5 after the hole is opened, and to prevent the column 5 from yielding and deforming due to stress caused by the hole.
[0061] The pin hole 3 is provided through the column 5. Preferably, there are at least two reinforcing plates 8, with reinforcing plates 8 provided on both sides of the column 5. The reinforcing plates 8 can be a single-layer plate structure or a multi-layer plate structure. The number and structure of the reinforcing plates 8 located at both ends of the pin hole 3 can be the same or different.
[0062] In some embodiments, the reinforcing plate 8 is a U-shaped cover plate, and the side plate edges of the U-shaped cover plate are welded to the column 5. The U-shaped cover plate has a bottom plate and two side plates, which are located at both ends of the pin hole 3 along the axial direction. The side plates have plate holes 81, and the bottom plate abuts against the end face of the column 5.
[0063] The reinforcing plate 8 adopts a U-shaped cover plate structure. After the U-shaped cover plate is matched with the column 5, it can simultaneously reinforce both sides of the column 5. Compared with the embodiment where the reinforcing plate 8 is a sheet structure, it can further simplify the assembly process of the end bracket 11 with column head 10 and improve the processing efficiency of the end bracket 11.
[0064] In some embodiments, the reinforcing plate 8 is a shell structure adapted to the shape of the column 5. One end of the shell structure is an open end, and the other end opposite the open end is a closed end. The closed end abuts against the end face of the column 5, and the shell structure covers the column 5 through the open end. In this embodiment, the shell structure not only has a plate hole 81 communicating with the pin hole 3, but also a through hole communicating with the main cable adjustment hole 4. In this embodiment, the shell structure can enhance the strength of the outer periphery of the column 5, further reducing the impact of the opening on the strength of the column 5.
[0065] The first end of the column head 10 of the column 5 has a rectangular cross-section perpendicular to the length of the column 5. The end of the column head 10 of the column 5 has four sides, two of which are arranged opposite each other for the pin holes 3, and the other two oppositely arranged sides are used for the main cable adjustment holes 4. The end of the column head 10 of the column 5 is generally cubic in shape, which reduces the difficulty of creating the pin holes 3 and the main cable adjustment holes 4.
[0066] The cross-section of the first end of the column 5 with the column head 10 along the length direction perpendicular to the column 5 can be the same as or different from the cross-section of the second end of the column 5 without the column head 10 along the length direction perpendicular to the column 5. Specifically, the cross-section of the second end of the column 5 along the length direction perpendicular to the column 5 can be rectangular, circular, or other polygonal.
[0067] Optionally, the area of the cross-section of the first end of the column 5 with the column head 10 along the length direction perpendicular to the column 5 is greater than the area of the cross-section of the second end of the column 5 without the column head 10 along the length direction perpendicular to the column 5. This makes the circumferential dimension of the first end of the column 5 greater than the circumferential dimension of the second end of the column 5, thereby making the strength of the first end of the column 5 greater than the strength of the second end of the column 5 and reducing the impact of the opening on the strength of the first end of the column 5.
[0068] Preferably, the dimensions of the first end of the column 5 gradually decrease from the second end of the column 5, or the first end of the column 5 makes a smooth transition to the second end of the column 5, so as to reduce stress concentration.
[0069] In some embodiments, a stepped surface may also be formed between the first end of the column 5 and the middle part of the column 5.
[0070] Although welding is unavoidable in this design, the welding is not applied at the connection point between the column head 10 and the column 5, i.e., it is not the main stress-bearing point of the column head 10. Therefore, the requirements for welding quality are not high, and the welding quality will not significantly affect the connection strength between the column head 10 and the column 5, thus achieving a balance between manufacturing and performance.
[0071] This solution also discloses an end bracket 11, which includes the column head 10 and the inclined tie assembly 9 described in any of the above solutions. One end of the inclined tie assembly 9 is connected to the extension section 21 of the pin 2 of the column head 10, and the other end of the inclined tie assembly 9 is fixed to the ground foundation.
[0072] Since the column head 10 has the above-mentioned technical effects, the end bracket 11 with the column head 10 also has the same technical effects, which will not be described in detail here.
[0073] like Figure 3 As shown, the connection position of the inclined tie assembly 9 and the extension section 21 of the pin 2 is located between the locking assembly and the reinforcing plate 8. The locking assembly can limit both the inclined tie assembly 9 and the pin 2 at the same time. It can limit the pin 2 not only along its own axis but also limit the inclined tie assembly 9 along the axis of the pin 2, preventing the inclined tie assembly 9 from shaking during operation and affecting its performance.
[0074] like Figure 2 As shown, in this scheme, the column 5 with column head 10 is anchored to the ground foundation through column tension pile 13, and the inclined cable assembly 9 is anchored to the ground foundation through inclined cable assembly tension pile 14, ensuring a stable connection between the column 5 and the inclined cable assembly 9 and the ground foundation. The column 5, the inclined cable assembly 9, the column tension pile 13 and the inclined cable assembly tension pile 14 form a triangular structure to provide a stable tension force to the main cable 1.
[0075] In some embodiments, the column tension pile 13 and the inclined tension component tension pile 14 have a connecting structure in between to improve the integrity and stability of the end support 11.
[0076] like Figure 2 As shown, a connecting plate is provided below the column 5. The connecting plate is fastened to the column tensile pile 13 by bolts. A fixing plate is provided on the side of the connecting plate facing the column 5. The shape of the fixing plate is adapted to the outer circumference of the column 5. The fixing plate is fastened to the outer circumference of the column 5 by bolts.
[0077] In some embodiments, the extension 21 of the pin 2 is connected to the tie rod 9 via a hinge bolt 12. Specifically, there are two hinge bolts 12, located at both ends of the extension 21 of the pin 2. One end of the hinge bolt 12 is rotatably connected to the pin 2, and the other end of the two hinge bolts is connected to a plate-shaped connector. The plate-shaped connector connects the two hinge bolts 12 together, and the portion of the plate-shaped connector between the two hinge bolts 12 is connected to the tie rod 9. This ensures that the tie rod 9 applies a uniform tension to both ends of the pin 2 through the plate-shaped connector and the hinge bolts 12, thus ensuring that the column 5 is subjected to uniform force at both ends along the axial direction of the pin 2. The hinge bolt 12 is located between the locking structure 6 and the reinforcing plate 8, and the locking structure 6 simultaneously limits the movement of the hinge bolt 12.
[0078] The cable tie assembly 9 is connected to the pin 2 via the hinge bolt 12, which allows for adjustment of the distance between the cable tie assembly 9 and the pin 2. The force exerted by the cable tie assembly 9 on the main cable 1 via the pin 2 can be flexibly adjusted according to actual needs.
[0079] The hinge bolt 12 can rotate relative to the pin 2, meaning that the angle adjustment of the cable tie assembly 9 and the main cable 1 can be adjusted independently, so that the force between the cable tie assembly 9 and the pin 2 is not affected when the angle of the main cable 1 is adjusted.
[0080] The cable-stayed component 9 is at least one of the following: cable-stayed cable, wire rope, cable-stayed steel pipe, and cable-stayed steel bar.
[0081] This solution also discloses a photovoltaic support system, including the end support 11 and the middle support described in any of the above solutions.
