Description

Technical Field

[0001] This utility model discloses a steel strand anchoring device for a mountain cable structure photovoltaic bracket, belonging to the field of photovoltaic bracket technology. Background Technology

[0002] Traditional mountain cable-stayed photovoltaic (PV) support structures largely draw on the construction methods of terrestrial cable-stayed PV structures. The central column is typically positioned perpendicular to the slope to ensure balanced tension on both sides of the steel strands. However, this design faces significant challenges in complex and varied mountain environments. Due to the irregularity of the slope, maintaining a perpendicular central column not only increases construction difficulty but also complicates precision. Existing construction equipment is stable in vertical operations, but errors increase significantly when working on inclined surfaces, making precise control of the tilt angle particularly difficult. This directly leads to inconsistent tension on the steel strands on both sides of the central column, causing the column to tilt and ultimately jeopardizing the stability and safety of the entire cable-stayed PV support structure. Summary of the Invention

[0003] This utility model overcomes the shortcomings of the prior art and proposes a steel strand anchoring device for a mountain cable structure photovoltaic support, characterized in that it includes: a central column, a U-bolt, an anchor head, and steel strands;

[0004] The central column is vertically set on the mountain slope and parallel to the normal direction of the horizontal plane;

[0005] The U-bolts are fixedly installed on the top of the central column;

[0006] The anchor head is located on one side of the U-bolt;

[0007] The steel strand passes through the U-bolt and the anchor head in sequence, and the anchor head is used to adjust the tension of the steel strand.

[0008] Preferably, steel pipes are also included;

[0009] The steel pipe is positioned between the anchor head and the U-bolt, and the steel strand passes through the steel pipe and is secured by the anchor head.

[0010] Preferably, the anchor head is located on the side of the U-bolt facing the slope.

[0011] Preferably, the anchor head further includes an anchor head clamp;

[0012] The anchor head clip is located on the side of the anchor head away from the U-bolt.

[0013] Preferably, the U-bolt is connected to the central column by bolting or welding.

[0014] Preferably, the steel pipe is parallel to the slope surface where the central column is located.

[0015] Preferably, pile foundations are also included;

[0016] The pile foundation is set on the mountain slope, and the central column is set on the pile foundation.

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: The mountain cable-stayed photovoltaic support structure of this utility model, by vertically arranging the central column instead of perpendicular to the mountain slope, greatly improves the construction accuracy and efficiency of the central column, reduces the construction difficulty caused by complex terrain, and ensures the stability of the support structure. Secondly, after passing through the central column, the steel strands are precisely anchored by anchor heads. Even if there are differences in the force on the steel strands on both sides of the column, their resultant force can still be vertically downward along the direction of the central column. This design effectively ensures the overall stability and safety of the photovoltaic support structure and avoids structural risks caused by uneven force distribution. Finally, the central column shares some of the vertical force originally borne by the end columns, making the force distribution of the entire photovoltaic structure more balanced and reasonable, significantly reducing the amount of structural engineering required for the end columns, saving material costs, and improving the economy and sustainability of the overall structure.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 2-3As shown, the mountain cable-stayed photovoltaic support system consists of a central column 1, two side columns 7, and steel strands 5 running through the hillside 8. The side columns 7 are located at the upstream and downstream positions of the hillside 8, respectively, while the central column 1 is situated between them, firmly rooted in the hillside 8. The two ends of the steel strands 5 are securely anchored to the two side columns 7, and their path passes through the top of the central column 1, forming a stable support network. The foundation of this system is supported by pile foundations 6.

[0024] In traditional design, ideally, the central column 1 should be strictly perpendicular to the slope 8. In this case, the tensions F1 and F2 borne by the steel strands 5 on both sides are equal in magnitude and symmetrical in direction, and their resultant force Fz will act directly along the axis of the central column 1, ensuring structural stability. However, in actual mountain project construction, due to complex terrain and high construction difficulty, it is often difficult to precisely control the angle α between the central column 1 and the slope, leading to deviations in the magnitudes of the tensions F1 and F2.

[0025] This deviation directly causes the direction of the actual resultant force Fz' to deviate from the original design direction of Fz in the central column 1, which in turn causes the entire steel strand 5 system to shift in the direction of Fz'. This shift not only disrupts the original mechanical balance but also greatly reduces the overall stability of the photovoltaic support structure, increases the risk of structural collapse, and poses a serious threat to the safe operation of the photovoltaic power station.

[0026] To address the problems existing in the prior art, this utility model proposes a new technical solution. The details are as follows:

[0027] Please see Figure 1 As shown, the purpose of this embodiment is to provide an anchoring device for the steel strand 5 of a mountain cable structure photovoltaic bracket. The device comprises: a central column 1, a U-bolt 2, an anchor head 3, and the steel strand 5. The central column 1 is vertically positioned on the mountain slope, parallel to the normal direction of the horizontal plane. The U-bolt 2 is fixedly positioned at the top of the central column 1. The anchor head 3 is positioned on one side of the U-bolt 2, and the steel strand 5 passes through the U-bolt 2 and the anchor head 3 in sequence. The anchor head 3 is used to adjust the tension of the steel strand 5.

[0028] Specifically, the mountain cable-stayed photovoltaic support structure of this invention significantly improves the construction accuracy and efficiency of the central column 1 by arranging it vertically rather than perpendicular to the mountain slope, reducing the construction difficulty caused by complex terrain and ensuring the stability of the support structure. Secondly, after passing through the central column 1, the steel strands 5 are precisely anchored by the anchor head 3. Even if there are differences in the force on the steel strands 5 on both sides of the column, their resultant force can still be vertically downward along the direction of the central column. This design effectively ensures the overall stability and safety of the photovoltaic support structure, avoiding structural risks caused by uneven force distribution. Finally, the central column 1 shares some of the vertical force originally borne by the end columns, making the force distribution of the entire photovoltaic structure more balanced and reasonable, significantly reducing the amount of structural engineering required for the end columns, saving material costs, and improving the overall economic efficiency and sustainability of the structure.

[0029] Furthermore, it also includes a steel pipe 4; the steel pipe 4 is set between the anchor head 3 and the U-bolt 2, and the steel strand 5 passes through the steel pipe 4 and is fastened by the anchor head 3.

[0030] This embodiment also includes a steel pipe 4, which is sleeved on the steel strand 5 between the anchor head 3 and the U-bolt 2.

[0031] Furthermore, steel pipe 4 is parallel to the slope surface where the central column 1 is located.

[0032] In this embodiment, the steel pipe 4 is parallel to the slope where the central column 1 is located.

[0033] Furthermore, the anchor head 3 is positioned on the side of the U-bolt 2 facing the slope.

[0034] Furthermore, the anchor head 3 also includes an anchor head clamp; the anchor head clamp is located on the side of the anchor head 3 away from the U-bolt 2.

[0035] Specifically, in this embodiment, an anchor head clamp is installed on the side of the anchor head 3 away from the U-bolt 2. The anchor head clamp is made of high-strength alloy steel, which has good wear resistance and fatigue resistance. During installation, the steel strand 5 is passed through the anchor head 3 and placed inside the anchor head clamp. A special tool is used to tighten the clamp to ensure that the steel strand 5 is firmly held. The application of the anchor head clamp can effectively improve the tension and stability of the steel strand 5.

[0036] Furthermore, the U-bolt 2 is connected to the central column 1 by bolts or welding.

[0037] Furthermore, it also includes pile foundation 6; pile foundation 6 is set on the mountain slope, and central column 1 is set on pile foundation 6.

[0038] like Figure 3As shown, the solid line represents the installation diagram of column 1 in the traditional mountain cable structure photovoltaic bracket, and the dashed line represents the installation diagram of column 1 in the mountain cable structure photovoltaic bracket of this utility model.

[0039] The installation method of the anchoring device for the steel strand 5 of the photovoltaic support structure in the mountain cable structure in this embodiment includes:

[0040] Step 1: Install the central column 1 vertically at the preset position on the slope;

[0041] Step 2: Fix U-bolts 2 at the top of the central column 1;

[0042] Step 3: Pass the steel strand 5 through the U-bolt 2 for initial fixation, and guide the steel strand 5 through the steel pipe 4 and anchor head 3. Secure the steel strand 5 through the clamping structure of the anchor head 3, and initially tension the steel strand 5.

[0043] Step 4: After the entire mountain cable structure photovoltaic support is installed, the details of the steel strands 5 are tensioned and adjusted by adjusting the tightness of the anchor head 3, so that the resultant tension force of the steel strands 5 on both sides of the central column 1 is vertically downward.
