Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a flexible photovoltaic support. Background Technology

[0002] In the field of photovoltaic power generation, the photovoltaic panel bracket is a key component for supporting and fixing photovoltaic panels, and its performance directly affects many factors such as the stability of the photovoltaic system, ease of installation, and land use efficiency.

[0003] Traditional fixed supports typically use steel beams to hold photovoltaic panels. While providing stable support, these supports are excessively heavy, difficult to install and transport, and their rigid structure offers almost no room for adjustment. Some improved solutions utilize flexible supports, which are photovoltaic support systems that use flexible materials (such as steel cables, steel strands, and flexible modules) as the main load-bearing and support structure. Compared to traditional fixed supports, flexible supports have greater deformation capacity and stronger adaptability. Their large-span cable-stayed structures can adapt to various complex terrains such as hillsides, tidal flats, and water treatment plants.

[0004] However, existing flexible supports also have some shortcomings, such as high bearing capacity requirements for pile foundations and insufficient adaptability to terrain. Especially in space-constrained locations, horizontally fixed photovoltaic panels will occupy a lot of space, resulting in insufficient space utilization. Utility Model Content

[0005] To address the problem of low space utilization in existing photovoltaic brackets, this utility model proposes a flexible photovoltaic bracket.

[0006] The specific technical solution is as follows:

[0007] A flexible photovoltaic support structure includes:

[0008] At least two columns are arranged parallel to each other on the ground. Each column is equipped with at least two prestressed anchor cables, which include a fixed cable and a side cable. Two adjacent columns are connected by the fixed cable, which is used to vertically fix the photovoltaic panel.

[0009] At least two side anchors are symmetrically arranged on both sides of the column, including ground anchor foundations fixed to the ground. The ground anchor foundations are connected to the adjacent column via side cables. By arranging parallel columns at intervals and connecting adjacent columns with fixing cables to vertically fix the photovoltaic panels, this structure forms a stable support frame, providing reliable vertical support for the photovoltaic panels. This ensures the stability of the photovoltaic panels under various environmental conditions and reduces the impact of swaying or displacement on power generation efficiency. The symmetrical arrangement of the side anchors on both sides of the column and their connection to the column via side cables enhances the lateral stability of the entire flexible photovoltaic support system, effectively resisting the effects of lateral forces such as wind and earthquakes, preventing lateral tilting or collapse of the support system, and improving the safety and reliability of the support system in complex environments.

[0010] Furthermore, the prestressed anchor cable also includes a fixing plate, a sleeve, a first compression anchor, and a cable head. The fixing plate has a through hole, and one end of the fixed cable is disposed in the through hole and tensioned to the fixing plate through the sleeve and the first compression anchor. The arrangement of the fixing plate, sleeve, first compression anchor, and cable head enables the fixed cable to achieve a firm tensioned connection with the fixing plate. By precisely controlling the tension force, the prestress of the fixed cable can be adjusted to better adapt to different geological conditions and load requirements, improve the overall stability and load-bearing capacity of the support, and facilitate installation and commissioning.

[0011] Furthermore, the cable head is fixedly connected to one end of the side cable. This fixed connection ensures a reliable connection between the side cable and other components of the prestressed anchor cable, enabling the side cable to effectively transmit tension and tightly connect the column and the side anchor together. This further enhances the integrity and stability of the support structure and prevents the side cable from loosening or falling off during use.

[0012] Furthermore, the prestressed anchor cable also includes a limiting plate, a second compression anchor, and a swivel bolt. The other end of the side cable passes through the limiting plate and is fixedly connected to the limiting plate via the second compression anchor. The limiting plate is connected to the ground anchor foundation via the swivel bolt. This combination of the limiting plate, the second compression anchor, and the swivel bolt allows for precise fixing and limiting of the other end of the side cable. The second compression anchor ensures a secure connection between the side cable and the limiting plate, while the limiting plate is flexibly connected to the ground anchor foundation via the swivel bolt. This design ensures the transmission of tension in the side cable and facilitates adjustments to the length and tension of the side cable during installation and commissioning, improving construction efficiency and the adaptability of the support system.

[0013] Furthermore, the swivel bolt is fixedly connected to the ground anchor foundation via a pin. Using a pin to fix the swivel bolt to the ground anchor foundation offers advantages such as convenient installation and disassembly, while ensuring connection reliability. When adjustment or maintenance of the support is required, it can be quickly disassembled and reinstalled, reducing maintenance time and costs. Moreover, the pin connection can withstand a certain shear force, ensuring connection stability under various working conditions.

[0014] Furthermore, there are two swivel bolts, each located on one side of the side cable. Having two swivel bolts on one side of the side cable allows for a more even distribution of the tension transmitted by the side cable, enhancing the connection stability between the limiting plate and the ground anchor foundation. This design effectively prevents loosening or damage to the connection due to excessive stress at a single point, improving the load-bearing capacity and reliability of the entire side anchor system, and further ensuring the safe operation of the flexible photovoltaic support.

[0015] Furthermore, the fixed and side cables are made of steel cables or steel strands. Steel cables or steel strands are chosen as the materials for the fixed and side cables because they possess advantages such as high strength, good flexibility, and corrosion resistance. High strength ensures that the cables will not break under large tensile forces, ensuring the stability of the support structure; good flexibility allows the cables to adapt to certain deformations, better accommodating complex terrain and minor displacements of the support structure; corrosion resistance extends the service life of the cables, reduces maintenance and replacement costs, and improves the economy and reliability of the entire flexible photovoltaic support structure.

[0016] Furthermore, the fixing cable is equipped with multiple pressure blocks for securing the photovoltaic panel. These pressure blocks allow for convenient and secure fixing of the photovoltaic panel to the cable. The distribution of these pressure blocks can be adjusted according to the size and shape of the photovoltaic panel, ensuring a flat and stable installation, reducing stress concentration caused by panel movement or displacement, improving the lifespan and power generation efficiency of the photovoltaic panel, and facilitating installation, disassembly, and maintenance.

[0017] The above technical solution has the following advantages or technical effects:

[0018] 1. This utility model provides reliable vertical support for photovoltaic panels through spaced parallel columns and fixed cables connecting adjacent columns, ensuring their stability and preventing swaying. Simultaneously, symmetrically arranged side anchors on both sides of the columns, connected to the columns by side cables, enhance the lateral stability of the entire support structure, effectively resisting the impact of lateral forces such as wind and earthquakes, preventing lateral tilting or collapse, and ensuring the safe operation of the photovoltaic system even in complex environments.

[0019] 2. The synergistic effect of components such as the fixing plate, sleeve, and compression anchor in prestressed anchor cables enables precise tensioning connections between the fixed cables and side cables. By controlling the prestress, the cables can better adapt to different geological conditions and load requirements, optimize the stress distribution of the support, and further improve the overall structural stability and load-bearing capacity. The fixed connection between the cable head and the side cable, the connection between the limiting plate and the side cable through the compression anchor, and the pin connection between the live bolt and the ground anchor foundation all ensure the robustness of the connections between the components.

[0020] 3. The connection design of the slip-knot bolts with the limiting plate and ground anchor foundation allows for convenient adjustment of the length and tension of the side cables during installation and commissioning. This flexibility greatly improves construction efficiency and reduces installation time and labor costs. Simultaneously, in later maintenance, adjustments and repairs can be quickly made according to actual conditions, reducing maintenance difficulty and costs. The application of detachable connection methods such as pin connections allows for rapid disassembly and reinstallation of relevant components when replacement or large-scale repairs are needed. No complex tools or operating procedures are required, reducing maintenance time and impacting the normal operation of the photovoltaic system, thus improving system maintainability.

Detailed Implementation

[0026] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figure 1As shown, a flexible photovoltaic support includes: two columns 1, two side anchors 2, and four prestressed anchor cables 3. The two columns 1 are arranged parallel to each other on the ground at intervals, and two prestressed anchor cables 3 are installed on each column 1, located at the upper and lower parts of the column 1 respectively. The specific positions are determined by the width of the photovoltaic panel and the installation height.

[0029] like Figure 2 As shown, each prestressed anchor cable 3 includes a fixed cable 3.1 and an edge cable 3.2. The fixed cables 3.1 at corresponding positions on two adjacent columns 1 are connected to each other, that is, the upper fixed cables 3.1 are connected and the lower fixed cables 3.1 are connected to form an upper and lower fixed structure. Multiple pressure blocks 3.11 for fixing photovoltaic panels are evenly distributed on each layer of fixed cables 3.1. The photovoltaic panels can be stably fixed by the upper and lower layers of fixed cables 3.1 to ensure their stability in various environments. The number of photovoltaic panels that can be fixed by a set of fixed cables 3.1 is at least one and at most three.

[0030] Two side anchors 2 are symmetrically arranged on both sides of the column 1, and each side anchor 2 includes a ground anchor foundation 2.1 fixed to the ground. One end of the side cable 3.2 in the prestressed anchor cable 3 is fixedly connected via a cable head 3.6, and the other end passes through a limiting plate 3.7 and is fixedly connected to the limiting plate 3.7 via a second compression anchor 3.8, as shown. Figure 3 As shown, the limiting plate 3.7 is then connected to the ground anchor foundation 2.1 via two slip bolts 3.9, and the slip bolts 3.9 and the ground anchor foundation 2.1 are fixedly connected by pins 3.10. The unilateral tensioning structure is as follows... Figure 4 As shown.

[0031] This embodiment is suitable for sites with a small area and relatively flat terrain. The combination of two columns 1 and side anchors 2 provides basic structural stability, and the design of the upper and lower layers of fixing cables 3.1 can firmly fix the photovoltaic panels, meet the power generation needs of the photovoltaic panels under normal lighting conditions, and at the same time, the installation and maintenance costs are low, and it is easy to operate and manage.

[0032] Example 2

[0033] A flexible photovoltaic support includes: two columns 1, two side anchors 2, and six prestressed anchor cables 3. The two columns 1 are arranged parallel to each other on the ground, and three prestressed anchor cables 3 are arranged vertically at intervals on each column 1, evenly distributed at different positions at the top, middle, and bottom of the column 1.

[0034] Each prestressed anchor cable 3 also includes a fixed cable 3.1 and an edge cable 3.2. The fixed cables 3.1 at corresponding positions on adjacent columns 1 are interconnected to form a three-layer fixing structure. The upper and middle layers of fixed cables 3.1 can fix one set of photovoltaic panels, while the middle and lower layers can fix another set, thus stably fixing a total of two sets of photovoltaic panels and increasing the number of photovoltaic panels that can be installed within a limited space. Each layer of fixed cables 3.1 is equipped with multiple pressure blocks 3.11 for fixing the photovoltaic panels.

[0035] Two side anchors 2 are symmetrically distributed on both sides of the column 1. The ground anchor foundation 2.1 of the side anchor 2 is connected to the adjacent column 1 through the side cable 3.2. One end of the side cable 3.2 is fixed to the cable head 3.6, and the other end is connected to the ground anchor foundation 2.1 through the limiting plate 3.7, the second compression anchor 3.8, the slip bolt 3.9 and the pin 3.10 to ensure the firmness of the connection.

[0036] The three-layer fixing structure of this embodiment can increase the number of photovoltaic panels that can be installed in a relatively compact space, thereby improving land utilization and power generation efficiency. The three-layer fixing cables 3.1 can better distribute the weight of the photovoltaic panels and external loads, such as wind and snow loads, enhancing the overall stability of the support structure. This is especially suitable for sites with abundant sunshine, limited land resources, and a certain scale of power generation. At the same time, this structure also facilitates appropriate adjustments to the installation of photovoltaic panels according to different sunlight angles and seasonal changes.

[0037] To further improve the wind resistance of the support structure, a stay cable can be added between column 1 and side anchor 2 to form a triangular support structure, thereby enhancing the lateral stability of the support structure.

[0038] Since the column 1 is installed on the pile foundation and connected to the pre-embedded bolts, the column should not be too high. Therefore, in order to prevent lateral collapse, the number of photovoltaic panels fixed in the vertical direction of the column 1 should not exceed three. At the same time, in order to avoid excessive stress on the side anchors 2, the number of columns 1 between two side anchors 2 should not exceed three.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
