Description

Technical Field

[0001] This invention belongs to the field of photovoltaic installation technology, and specifically relates to an installation method for a flexible photovoltaic bracket. Background Technology

[0002] The scale of photovoltaic (PV) construction is continuously expanding in mountainous areas. However, mountainous terrain is complex, with steep slopes, poor geological conditions, and dense vegetation. Traditional rigid PV support systems are difficult to install, have long installation cycles, are costly, cause severe damage to the terrain, and have low land utilization rates. Traditional support systems require the construction of construction platforms, involve a lot of high-altitude work, pose high safety risks, and cause significant ecological disturbance. Flexible PV support systems use high-strength cables tensioned and fixed to the support frame to form a large-span flexible support surface for installing PV modules. By adjusting the height of the support columns and the tension of the cables, they can easily overcome terrain obstacles, making them particularly suitable for uneven ground such as hills, mountains, slopes, and ponds, greatly reducing land leveling costs and environmental damage. However, flexible PV support systems are not strong enough to resist wind vibration. Under the influence of wind, the module array may experience significant flutter or swaying. Continuous and violent shaking can cause microcracks or even breakage of the PV cells, seriously affecting power generation efficiency and module lifespan.

[0003] Chinese patent application CN120768213A, entitled "Double-row Flexible Photovoltaic Support Device and Photovoltaic Array Installation Method," discloses a flexible photovoltaic support system comprising multiple main supports arranged sequentially. Each main support includes a pipe pile foundation, with support components and crossbeams fixedly connected to the foundation. Four main cable supports are located at the top of the crossbeams, through which four main cables pass sequentially. The tops of the crossbeams of the two main supports at the ends of the double-row flexible photovoltaic support system are equipped with main cable anchors corresponding to the main cable supports, used to tension and anchor the ends of the main cables. The two main supports at the ends are tensioned and secured to the ground by end anchors. At least some adjacent main supports are provided with wind-resistant supports, which are tensioned and secured to the ground by auxiliary anchors. The wind-resistant supports between adjacent main supports suppress wind-induced vibration, reduce the risk of module damage, and improve the safety, stability, and reliability of the photovoltaic array. The wind-resistant support in the aforementioned patent is a planar structure, and the connection point with the main cable is located on a straight line. It can only provide wind-resistant support in one direction. When the wind force is strong or the wind direction is changeable, the rigidity and stability of the photovoltaic support are not high enough. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an installation method for a flexible photovoltaic support, which, by installing a wind-resistant structure with a stable geometric framework, enables the flexible photovoltaic support to resist winds from different directions and has strong wind resistance and shock absorption performance, thereby improving the stability and reliability of the flexible photovoltaic support.

[0005] This invention discloses an installation method for a flexible photovoltaic support, comprising the following steps: S1. Construction preparation and foundation acceptance; S2, Mounting bracket structure; S3. Lay the pre-tensioned main cable group on the support structure, perform tension test on the main cable group, and install the anchor on the main cable group; S4. Install photovoltaic modules on the main cable assembly using photovoltaic module connectors; S5. Install a wind-resistant system on the main cable assembly; the wind-resistant system installation steps include connecting and installing the four-corner pyramid wind-resistant structure to the main cable assembly and connecting and installing the wind-resistant cable to the four-corner pyramid wind-resistant structure. S6. System overall acceptance and adjustment.

[0006] This installation method improves the wind resistance of flexible photovoltaic (PV) systems by installing a stable, geometrically-based pyramidal wind-resistant structure on the PV system. The pyramidal structure provides multiple load transfer and distribution paths, offering good stiffness and stability while forming spatial force transmission paths, thus exhibiting strong resistance to wind loads from different directions. Furthermore, the highly redundant pyramidal structure allows for force redistribution through other paths even in the event of failure of a few members, providing a high safety margin.

[0007] Furthermore, the installation of the support structure in S2 includes the following steps: S21. Install the end bracket structure and perform bolt torque testing; S22. The end support structure is installed with end stay cables and tensioned and tested. S23. Install the central support structure and roller nodes.

[0008] During construction, parameters such as tension force, bolt torque, and cable sag are strictly controlled to ensure structural safety and system stability.

[0009] Furthermore, the four-corner pyramid wind-resistant structure includes two four-corner pyramids and two support rods. The base of each four-corner pyramid has two base rods. The two four-corner pyramids are respectively set on adjacent main cable groups. The apex of each four-corner pyramid is located below the plane where the main cable group is located. The two parallel base rods on the base of each four-corner pyramid are respectively connected to the cables of the main cable group. The first end of each support rod is connected to the apex of one four-corner pyramid, and the second end of each support rod is respectively connected to the near ends of the two base rods of the other four-corner pyramid.

[0010] The four parallel base rods on the quadrilateral base of the four-corner pyramid frame structure intersect with two parallel cables to form four intersection points, integrating the two parallel cables in the main cable group into a whole. This effectively improves the overall stiffness and provides an intermediate support for the cables, which is equivalent to reducing the span of the cables. This reduces the deflection of the cables tensioned and fixed on the support frame, thus resisting the sagging caused by external wind loads. The struts are connected to the base rod of one four-corner pyramid frame and the cone top of another four-corner pyramid frame, providing mutual support and reducing the deflection of adjacent main cable groups. The resulting stable triangular structure helps the cables withstand greater wind loads. At the same time, integrating the two four-corner pyramid frames into a whole improves the overall wind resistance.

[0011] Furthermore, the wind-resistant structure of the quadrangular pyramid frame also includes a triangular connecting plate. S5 also includes the installation of the triangular connecting plate. One vertex of the triangular connecting plate is connected to the second end of the support rod, and the other vertex is connected to the near end of the bottom rod on the adjacent quadrangular pyramid frame.

[0012] The triangular connecting plate between the strut and the base allows the wind-resistant structure to deform and sway slightly to release and dissipate energy. At the same time, it also allows the strut to connect to the four-corner pyramid frame with a large elevation difference.

[0013] Furthermore, the support rod is a C-shaped support rod; the support rod is provided with through holes for bolt connection along its length.

[0014] The C-shaped cross-section of the strut provides high structural strength. A row of through holes along its length allows for multiple bolts to connect the C-shaped strut to other components, offering flexible and adjustable connection positions. Wind pressure loads are distributed through multiple bolts, avoiding stress concentration at single points. While rigid wind-resistant structures experience continuous small-amplitude vibrations under wind, the bolted connections, being flexible, possess a certain degree of deformation capacity, better absorbing and releasing vibration energy.

[0015] Furthermore, the wind-resistant cable includes a fixing cable and a ground anchor cable, with several fixing cables arranged at an angle; the installation of the wind-resistant cable includes tensioning and fixing the fixing cable and the ground anchor cable, specifically: one end of the fixing cable is connected to the top of the four-corner pyramid frame, and the other end is connected to the bottom of the support frame; one end of the ground anchor cable is connected to the top of the four-corner pyramid frame, and the other end is anchored to the ground.

[0016] Multiple connection points are provided by fixing cables and ground anchor cables. The cables are set at an angle to form a stable connection structure, which improves the stiffness and stability of the wind-resistant structure and enhances its wind resistance performance.

[0017] Furthermore, the ends of the main cable in the main cable assembly and the wind-resistant cable in the wind-resistant system are connected and fixed by compression anchors, wire rope clamps and swivel rings.

[0018] The system employs a plastic interlocking mechanism between steel strands and extruded anchors. By applying pressure to the anchors using hydraulic equipment, irreversible deformation occurs between the extruded anchors and the steel strands. This eliminates the risk of loosening caused by wind vibration and other factors associated with traditional bolts, resulting in stronger dynamic adaptability, allowing for displacement within a small range, and better wind and earthquake resistance.

[0019] Furthermore, the photovoltaic module installation steps are as follows: the photovoltaic module is connected to the main cable assembly through connectors, and is installed by sliding using its own weight or mechanical power based on the height difference.

[0020] The installation process is simplified by using the weight of the photovoltaic modules to slide along the cableway, avoiding the high-altitude work methods used in traditional photovoltaic module installation, reducing workers' exposure time at height, and lowering safety risks.

[0021] The present invention has the following beneficial effects: The flexible photovoltaic (PV) support installation method provided by this invention involves placing a stable, spatially structured, pyramidal wind-resistant structure between the flexible PV modules. This wind-resistant structure provides good rigidity and stability, forming a spatial force transmission path and exhibiting good resistance to wind loads from different directions. It also possesses high safety reserves and overall wind resistance strength. The possibility of damage to the flexible PV support under wind vibration is reduced, thus extending the lifespan of the PV modules. The flexible PV support constructed using the installation method provided by this invention is suitable for PV power plant construction in complex terrain conditions such as mountains and hills, offering significant economic and environmental benefits.

Detailed Implementation

[0024] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of the invention. It should be noted that the terms "set," "connect," and "install" should be interpreted broadly, for example, referring to direct connection, indirect connection, or integral connection. Those skilled in the art will understand the specific meaning of the above terms in the present invention according to the specific circumstances. The terms "vertical," "horizontal," "left," "right," and similar expressions are for illustrative purposes only and do not indicate the only embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0025] like Figure 1 As shown, the specific installation method of the flexible photovoltaic support is as follows: First, conduct construction preparation and foundation acceptance; Secondly, install the end bracket structure and perform bolt torque testing; such as Figure 8 As shown, the support frame 02 at the end of the flexible photovoltaic bracket is an end bracket structure. The end bracket structure includes a column, an end bracket steel beam 101, an end cross brace 102, an end steel column 103, an end main cable three-eyed column head 104, an anti-loosening anchor 105, a steel pipe 106, a compression anchor for fixing the main cable 107, an end stay cable U-bolt 108, a compression anchor for fixing the stay cable 109, and an end stay cable 110.

[0026] Then, after installing the end stay cable 110, tensioning and testing were carried out. The tension of the end stay cable 110 and the tension of the main cable met the design requirements. During the tensioning process, the load was applied in stages, with tension control as the main method and deflection control as the secondary method.

[0027] Next, install the central support structure and roller nodes, such as... Figure 5 As shown, the support frame 02 in the middle of the flexible photovoltaic support is the central support structure, as... Figure 9 and Figure 10 As shown, the central support structure includes a central support steel column 201, ear plate 202, liquid cylinder structure 203, drum side plate one 204, drum bottom plate 205, drum side plate two 206, main cable tensioning drum sleeve 207, and rope clamp 208; next, the main cable is laid, pre-tensioned, tensioned, and tested; and the main cable sheath, extrusion anchor, and anti-corrosion treatment are installed.

[0028] Then proceed with the assembly and initial connection of the windproof structure, such as... Figure 6 As shown, the windproof structure includes a four-corner pyramid frame 10, support rods 20, and a base rod 11. Support rods 20 are C-shaped steel support rods. The four-corner pyramid frame 10 is connected and fixed to the main cable assembly 01 via #15 steel wire rope clamps 304. Figure 5 As shown, one end of the fixing cable 03 is connected to the top of the four-corner pyramid frame 10, as... Figure 7 As shown, the other end of the fixing cable 03 is a 16# heart-shaped ring 307, which is connected and fixed to the support frame 02 via a 14# wire rope clamp 308; the ends of the main cable and the fixing cable 03 are fixed using compression anchors, wire rope clamps, and heart-shaped rings to ensure reliable connection; Figure 11 As shown, the photovoltaic module 00 is slidably installed and secured by installing and connecting aluminum alloy connector 401 and stainless steel clamp 402. The photovoltaic module 00 is connected to the main cable through the connector and is slidably installed by its own weight or mechanical power. During the installation process, the sliding speed needs to be controlled to avoid collisions.

[0029] Next, the wind-resistant system is installed, including the tensioning and fixing of the fixing cable 03, anti-lifting cable, connecting cable, and ground anchor cable 04.

[0030] Finally, conduct overall system acceptance and adjustments.

[0031] The overall installation flowchart is as follows: Figure 1 As shown in the diagram, the installation process after the foundation strength reaches 70% is as follows: Figure 2 As shown in the diagram, the installation process after the foundation strength reaches 90% is as follows: Figure 3 As shown, the installation flowchart of the windproof system is as follows: Figure 4 As shown.

[0032] The installation of flexible photovoltaic brackets should be carried out in windless or light wind weather. After installation, the tightness of the bolts and the tension of the wind-resistant system should be checked in a comprehensive manner, and secondary adjustments should be made if necessary.

[0033] like Figure 5 As shown, the flexible photovoltaic support provided by the present invention is configured as follows: the flexible photovoltaic support includes multiple groups of main cable assemblies 01 arranged in parallel and multiple support frames 02, with both ends of the multiple groups of main cable assemblies 01 correspondingly mounted on the multiple support frames 02; as shown... Figure 6 As shown, the two quadrangular pyramidal frames 10 in the wind-resistant structure are respectively set on adjacent main cable assemblies 01, with the pyramidal apexes of the quadrangular pyramidal frames 10 facing downwards and located below the plane where the main cable assembly 01 is located. Figure 5 and Figure 7 As shown, the flexible photovoltaic support also includes two fixing cables 03 arranged at an angle. One end of the fixing cable 03 is connected to the top of the four-corner pyramid frame 10, and the other end is connected to the bottom of the support frame 02 to further enhance the overall integrity of the photovoltaic support and improve its wind resistance. Figure 5 As shown, the flexible photovoltaic support also includes ground anchor cable 04. One end of the ground anchor cable 04 is connected to the top of the pyramidal frame 10, and the other end is grounded to increase the tensile strength of the photovoltaic support. After the wind-resistant structure of the flexible photovoltaic support is installed, the fixing cable 03 and the ground anchor cable 04 are installed.

[0034] like Figure 5 and Figure 6 As shown, this invention discloses the specific structure of a wind-resistant structure installed on a flexible photovoltaic support. The wind-resistant structure includes two quadrangular pyramidal frames 10 and two support rods 20. The two quadrangular pyramidal frames 10 are respectively arranged on adjacent main cable assemblies 01. The base of the quadrangular pyramidal frame 10 is provided with two parallel bottom rods 11, which are perpendicularly connected to the cables of the main cable assembly 01. The apex of the quadrangular pyramidal frame 10 faces downward and is located below the plane of the main cable assembly 01. The first end of the support rod 20 is connected to the apex of one quadrangular pyramidal frame 10, and the second end of the support rod 20 is respectively connected to the proximal ends of the two bottom rods 11 of the other quadrangular pyramidal frame 10. Figure 6As shown, based on the aforementioned wind-resistant structure, a triangular connecting plate 30 is also provided at the second end of the strut 20. The strut 20 is connected to two vertices of the triangular connecting plate 30, and the base rod 11 is connected to the third vertices of the triangular connecting plate 30. The triangular connecting plate 30 between the strut 20 and the base rod 11 allows the wind-resistant structure to undergo small-amplitude deformation and swaying to release and dissipate energy. Simultaneously, the height of the triangular connecting plate allows the strut 20 to connect two quadrangular pyramidal frames 10 with a height difference. As a further improvement to the aforementioned wind-resistant structure, the base of the quadrangular pyramidal frame 10 is provided with two intersecting base rods 11. The midpoints of the base rods 11 intersect and connect in an X-shape, and the four endpoints are connected to parallel cables, forming a stable connection structure on the bottom surface of the quadrangular pyramidal frame 10, increasing the stiffness and tensile strength of the wind-resistant structure.

[0035] The four-corner pyramid frame 10 in the wind-resistant structure has a stable geometric framework and load transfer and distribution paths in multiple directions, providing good stiffness and stability and forming spatial force transmission paths, thus exhibiting good resistance to wind loads from different directions. Simultaneously, the four-corner pyramid frame 10 is a highly redundant structure, allowing for force redistribution through other paths even if a few members fail, providing a high safety margin. The struts 20 are connected to the base member 11 of one four-corner pyramid frame 10 and the cone apex of another four-corner pyramid frame 20, providing mutual support and integrating the two four-corner pyramid frames 10 into a unified whole, improving the overall wind resistance. Several wind-resistant structures are installed on the flexible photovoltaic support. Two base rods 11, located on the quadrilateral pyramidal base of the quadrangular pyramidal frame 10, intersect with two parallel cables to form four intersection points. This integrates the two parallel cables in the main cable group 01 into a single unit, effectively improving overall stiffness and providing intermediate support for the cables. This is equivalent to reducing the cable span, thereby reducing the deflection of the cables tensioned and fixed to the support frame, resisting sagging caused by external wind loads. Support rods 20 are connected to the base rod of one quadrilateral pyramidal frame 20 and the apex of another quadrilateral pyramidal frame 20, providing mutual support and reducing the deflection of adjacent main cable groups. The resulting stable triangular structure helps the cables withstand greater wind loads. Due to the installation of the aforementioned wind-resistant structures with stable geometry and multiple load transfer and distribution paths, the wind resistance of the flexible photovoltaic support is improved.

[0036] Compared with traditional rigid photovoltaic supports, the flexible photovoltaic support provided by this invention has the following advantages: I. Lightweight Structure. Traditional rigid photovoltaic support systems rely on high-strength steel to construct multi-layered frame structures, requiring the configuration of more than ten types of standard components such as columns, beams, and diagonal braces. Each node requires precise assembly with bolts of different specifications and quantities, making the installation process cumbersome. Flexible support systems, such as… Figure 5As shown, a spatial tension structure is formed by using prestressed steel cables to construct the main cable group 01. The axial tensile properties of the high-strength cable structure are used to achieve structural self-balancing, reducing steel consumption by 60%, which is more conducive to transportation and storage and reduces construction costs.

[0037] II. Modular Installation Reduces Safety Risks. Traditional rigid supports require on-site assembly of multiple components, and the time spent adjusting the tilt angle and tightening at height is lengthy, posing a significant risk of falls. This structural system adopts modular prefabricated units. The tilt angle of the support frame 02 is prefabricated in the factory according to the optimal tilt angle of the photovoltaic array in the region. On-site, only the prefabricated support unit needs to be hoisted and tightened before cable net tensioning. The prestress of the cable body is then applied to the design value using winches and jacks. Finally, the nodes are locked using anchors. The installation of the components can be carried out by sliding along the cableway using the self-weight of the photovoltaic modules 00 due to the height difference, simplifying the installation process. This process shifts most of the high-altitude work to ground operations, reducing workers' exposure time at height and lowering safety risks.

[0038] Third, it exhibits strong adaptability to complex terrain and minimal ecological disturbance. Currently, mountain photovoltaic projects often face challenges such as fragmented terrain, steep slopes, and dense vegetation cover. Flexible supports, relying on a prestressed cable net system, can traverse gullies, steep slopes, and densely vegetated areas, achieving large-span spatial arrangements of 350-500 meters, with single spans reaching 35-50 meters, significantly improving terrain adaptability. The foundation construction of the flexible support frame (02) requires no large-scale excavation, reducing ecological disturbance, improving land utilization, and offering high environmental and water conservation benefits.

[0039] IV. Excellent seismic and wind resistance, strong dynamic adaptability, and structural stability. Compared to traditional rigid photovoltaic supports that rely on bolt friction for fastening, the flexible support structure adopts a plastic interlocking mechanism between steel strands and extrusion anchors. By applying pressure to the anchors through hydraulic equipment, irreversible deformation occurs between the extrusion anchors and the steel strands, eliminating the risk of loosening caused by wind vibration and other factors, resulting in stronger dynamic adaptability, allowing for displacement within a small range, and better wind and seismic resistance.

[0040] Fifth, the construction process is standardized, the procedures are clear, and quality control is convenient, making it suitable for large-scale mountain photovoltaic projects.

[0041] The lightweight, modular, and low-intervention cable-structure flexible photovoltaic support system provided by this invention offers advantages such as lightweight design, modularity, strong terrain adaptability, construction safety, and minimal ecological disturbance during installation. The system includes steps such as foundation acceptance, support installation, cable tensioning, component installation, and wind-resistant system installation. During construction, parameters such as tension force, bolt torque, and cable sag must be strictly controlled to ensure structural safety and system stability. All steel components should undergo anti-corrosion treatment, and on-site assembly requires careful handling to avoid damaging the galvanized layer. Component installation is best carried out in windless or lightly windy weather. After installation, a comprehensive inspection of bolt tightness and wind-resistant system tension is necessary, with secondary adjustments made if required.

[0042] The installation method of a flexible photovoltaic bracket provided by the present invention has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The descriptions of the embodiments above are only for the purpose of helping to understand the core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
