[0026] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present utility model. However, those skilled in the art should clearly understand that the present utility model can also be implemented in other embodiments without these specific details. In other cases, the detailed descriptions of well-known systems and devices are omitted to avoid unnecessary details from interfering with the description of the present utility model.

[0027] The following further describes the preferred technical solutions of the present utility model in conjunction with the accompanying drawings and embodiments.

[0028] As Figure 1 shown, in the mountain cable structure photovoltaic support, the steel strand 3 is generally arranged parallel to the slope surface 2. The steel strand 3 located on the mountainside is supported by a number of middle columns 1. The head and tail ends of the steel strand 3 are respectively passed through the end columns 4 located at the mountaintop and the mountain bottom and are tensioned and fixed by the anchor 31. To ensure the stability of the entire photovoltaic support, a cable anchor 5 is also provided on the other side of the end column 4 to provide tension. The tension of the cable anchor 5 is balanced with the tension of the steel strand 3 to ensure the structural stability of the entire cable structure photovoltaic support. In mountain projects, due to the diverse terrains and varying landforms, the steel strand 3 has an elevation angle or a depression angle B as Figure 3 shown, and is not perpendicular to the upright end column 4. Different elevation angles or depression angles of the steel strand 3 require different lengths and angles of the cable anchor 5, resulting in various forms of the cable anchor 5 components, difficulty in standardization, and an increase in on-site construction workload.

[0029] Based on this, the present utility model provides a cable anchor 5 adjusting device for a mountain cable structure photovoltaic support, including an end anchor 6, an end column 4, a cable anchor 5, and a tensioning assembly;

[0030] The end anchor 6 is buried in the foundation on the side of the end column 4 away from the cable structure;

[0031] One end of the cable anchor 5 is fixed to the top of the end column 4, and the other end is fixed to the end anchor 6;

[0032] One end of the tensioning assembly is connected between the two ends of the cable anchor 5, and the other end is fixed at a preset position for applying a downward tension to the cable anchor 5.

[0033] Specifically, in this embodiment, the end column 4 is vertically arranged in the foundation through a pile foundation 41. The end anchor 6 is buried in the foundation on the side of the end column 4 away from the cable structure and is located in the foundation at a preset distance from the end column 4, where the preset distance is adjusted according to the actual project.

[0034] Furthermore, as Figure 2 shown, this device further includes an end plate 7; the end plate 7 is arranged at the top of the end column 4; through holes are provided on the end plate 7, and one end of the cable anchor 5 passes through the through holes and is fixed on the end plate 7.

[0035] Specifically, the end plate 7 is located at the upper end of the end column 4, and its specific position can be adjusted by those skilled in the art according to the actual project. In this embodiment, the end plate 7 is located at the top of the end column 4.

[0036] In practical applications, the end plate 7 is welded to the end column 4.

[0037] Both ends of the cable anchor 5 are respectively fixed to the end plate 7 and the end anchor 6. Specifically, through holes are provided on the end plate 7, and one end of the cable anchor 5 passes through the through holes and is fixed to the end plate 7. The other end of the cable anchor 5 is fixed to the end anchor 6 through a specific connection method.

[0038] One end of the tensioning assembly is connected between the two ends of the cable anchor 5, and the other end is fixed at a preset position for applying a downward pulling force to the cable anchor 5.

[0039] In the present utility model, the cable anchor 5 is tightened by the tensioning assembly, causing it to bend downward, and then a downward pulling force is provided to the cable anchor 5 to counteract the uplift force on the end column 4. Based on this, the other end of the tensioning assembly can be fixed in the foundation between the end anchor 6 and the end column 4, or can be fixed at the lower end of the end column 4. The present utility model does not limit the specific position of the lower end, and those skilled in the art can determine its specific position according to the actual project. In this embodiment, the specific position of the lower end is the bottom end of the end column 4.

[0040] Specifically, the tensioning assembly includes a steel wire rope 8 and a fixing member; one end of the steel wire rope 8 is wound around a predetermined position of the cable anchor 5 and fixed through the fixing member; the other end of the steel wire rope 8 is fixed to the bottom end of the end column 4. In this embodiment, the predetermined position is specifically the middle position of the length of the cable anchor 5.

[0041] Specifically, to ensure the stable connection of the steel wire rope 8, the tensioning assembly further includes a support; the support is arranged at the bottom end of the end column 4; the other end of the steel wire rope 8 is fixed to the support.

[0042] In this embodiment, a support hole is provided on the support, and the steel wire rope 8 passes through the support hole and is fixed through the fixing member.

[0043] In this embodiment, the fixing member is specifically selected as a clamp 9.

[0044] As Figure 3 shown, in conventional projects, the steel strand 3 in the cable structure is fixed to the top end of the end column 4 through the anchor 31. In mountainous areas, due to the change of the hillside terrain, the included angle between the steel strand 3 and the end column 4 changes with the hillside terrain. Therefore, as Figure 2As shown by the dashed line, the angle between the conventional cable anchor 5 and the end column 4 remains unchanged, and thus it cannot well adapt to the mountain cable structure photovoltaic support with variable terrain. For the cable anchor 5 adjusting device of the present utility model, the cable anchor 5 is tensioned and fixed by the steel wire rope 8, so that the included angle C between the cable anchor 5 and the end column 4 can well adapt to the change of the included angle A between the steel strand 3 and the end column 4. At the same time, the steel wire rope 8 tensions the cable anchor 5 and bends it towards the side close to the end column 4, so that the vertically downward tension received by the cable anchor 5 increases, and then part of the uplift force received by the end column 4 is offset, so that the required uplift bearing capacity of the end column 4 is reduced, and the length and size cross-section of the end column 4 are reduced.

[0045] Therefore, compared with the traditional form of the cable anchor 5, the cable anchor 5 adjusting device in the present utility model significantly improves the standardization level of the installation process. This device can flexibly adapt to the steel strands 3 with different pitch angles and achieve precise adjustment of the length and angle of the cable anchor 5. This feature makes the present utility model have a wider applicability in complex and changeable mountain projects, greatly improving the construction convenience and efficiency.

[0046] By adopting the cable anchor 5 adjusting device of the present utility model, the steel wire rope 8 will bend the cable anchor 5 towards the side close to the end column 4 during the process of tensioning the cable anchor 5. This design effectively increases the vertical tension of the cable anchor 5, thereby reducing the uplift bearing capacity that the end column 4 needs to bear. Therefore, the length and size cross-section of the end column 4 can be correspondingly reduced, thereby reducing the engineering quantity in the mountain photovoltaic project and lowering the cost. At the same time, this design also helps to improve the stability and safety of the whole structure.

[0047] The above are only several embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model is disclosed as above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art, without departing from the scope of the technical solution of the present utility model, making some changes or modifications using the disclosed technical content is equivalent to equivalent implementation cases and all belong to the scope of the technical solution.
