Technical Field

[0001] This invention relates to the field of photovoltaic equipment technology, specifically to a photovoltaic support structure and its construction method. Background Technology

[0002] A photovoltaic (PV) system mainly consists of PV modules, support structures, cables, and control equipment. The support structure is a crucial component, used to support the PV modules to achieve the optimal angle of sunlight. Currently, fixed support structures are widely used, employing a beam-column frame system. These structures typically have small column spacing (less than 5 meters), and their installation presents challenges and a longer construction period in complex terrains such as mountains or hills. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects of difficult installation and long construction period of photovoltaic brackets in the prior art, thereby providing a photovoltaic bracket with simple structure and convenient installation and its construction method.

[0004] To address the aforementioned problems, the present invention provides a photovoltaic support structure, comprising: multiple columns arranged in a row; and cables connected to all of the columns, with both ends of the cables tensioned and anchored to a foundation, the cables being adapted to support and connect photovoltaic modules.

[0005] As a preferred technical solution of the photovoltaic bracket of the present invention, the bottom of the column is fixedly connected to the foundation, and the top of the column is hinged to the cable.

[0006] As a preferred technical solution of the photovoltaic bracket of the present invention, the bottom of the column is hinged to the base so that the column can swing along the tension direction of the cable, and the top of the column is hinged to the cable.

[0007] As a preferred technical solution of the photovoltaic support of the present invention, the column includes a first column and a second column. There are two first columns arranged opposite to each other. The bottom of the first column is fixedly connected to the foundation. The second column is located between the first columns. The bottom of the second column is hinged to the foundation so that the second column can swing along the tension direction of the cable. The top of the first column and the top of the second column are both hinged to the cable.

[0008] The present invention also provides a method for constructing a photovoltaic support structure, comprising the following steps:

[0009] Multiple columns are arranged in a row on the foundation;

[0010] Connect the cable to the top of the column;

[0011] Tension the cable;

[0012] The two ends of the cable are anchored to the foundation.

[0013] As a preferred technical solution of the construction method of the photovoltaic support of the present invention, the tensioning of the cable includes: performing a first tensioning on one or both ends of the cable, wherein the tension force of the first tensioning is less than a preset value; installing the photovoltaic module on the cable; and performing a second tensioning on one or both ends of the cable, wherein the tension force of the second tensioning reaches the preset value.

[0014] As a preferred technical solution for the construction method of the photovoltaic bracket of the present invention, the tension force of the first tensioning is 50% or 70% of the preset value.

[0015] As a preferred technical solution of the construction method of the photovoltaic support of the present invention, the method of arranging multiple columns in a row on the foundation includes: pouring the foundation; fixing or hinged the bottom of the columns to the foundation.

[0016] As a preferred technical solution of the construction method of the photovoltaic bracket of the present invention, the connection of the cable to the top of the column includes: when the bottom of the column is fixed to the foundation, the cable is hinged to the top of the plurality of columns so that the column is installed vertically; when the bottom of the column is hinged to the foundation, the top of the column is installed at an angle toward one end of the cable, and the cable is hinged to the top of the plurality of columns.

[0017] As a preferred technical solution of the construction method of the photovoltaic support of the present invention, the method of arranging multiple columns in a row on the foundation includes: pouring the foundation; fixing the bottom of the first column among the columns to the foundation, hinge the bottom of the second column among the columns to the foundation, and the second column is located between the first columns.

[0018] As a preferred technical solution of the construction method of the photovoltaic support of the present invention, the connection of the cable to the top of the column includes: when tensioning both ends of the cable, the second column located in the middle position is installed vertically, and the tops of the second columns on both sides are installed inclined towards the middle position. After tensioning both ends of the cable, the second columns on both sides located in the middle position swing to a vertical state following the deformation of the cable; when tensioning one end of the cable, the top of the second column is installed inclined away from the tensioning end of the cable. After tensioning one end of the cable, the second column swings to a vertical state following the deformation of the cable.

[0019] The present invention has the following advantages:

[0020] 1. The photovoltaic support structure of the present invention consists of columns and cables. Multiple columns are arranged in a row to form a support foundation. The cables are connected to multiple columns, and both ends of the cables are tensioned and anchored to the foundation. The cables are suitable for bearing and connecting photovoltaic modules, so that the entire photovoltaic support structure is tensioned, forming a flexible support structure with good structural stability and toughness. Therefore, the overall structure of the photovoltaic support structure in this embodiment is simple. During construction, only the columns and cables need to be combined, which simplifies the construction steps and shortens the construction time. Moreover, the column form construction is more flexible and can adapt to construction in various complex terrain scenarios (such as mountainous or hilly areas). The spacing of the columns can also be adjusted as needed, making it highly applicable.

[0021] 2. In the photovoltaic support system of this invention, the bottom of the column is fixedly connected to the foundation, and the top of the column is hinged to the cable. In this design, the bottom of the column is rigidly connected to the foundation, ensuring the connection strength between the column and the foundation. The column will not deform when the cable is tensioned, thus ensuring the rigidity and strength of the entire photovoltaic support system. This system is suitable for the construction of photovoltaic support systems with large spans.

[0022] 3. In the photovoltaic support system of this invention, the bottom of the column is hinged to the foundation, allowing the column to swing along the tension direction of the cable. The top of the column is also hinged to the cable. In this design, the hinged connection between the column and the foundation replaces the rigid connection, making construction simpler and more convenient. Furthermore, the tensioned and anchored cables at both ends to the foundation provide lateral stiffness, ensuring the structural strength of the photovoltaic support system. This system is suitable for the construction of photovoltaic support systems with smaller spans.

[0023] 4. The photovoltaic support structure of this invention includes a first column and a second column. Two first columns are provided and arranged opposite each other. The bottom of the first column is fixedly connected to the foundation. The second column is located between the first columns, and its bottom is hinged to the foundation so that it can swing along the tension direction of the cable. The tops of both the first and second columns are hinged to the cable. In this design, the rigid connection between the bottom of the first column and the foundation provides a fulcrum for the construction of the second column. The hinged connection between the bottom of the second column and the foundation instead of a rigid connection simplifies construction and saves cost and time. The ability of the second column to swing along the tension direction of the cable allows for position adjustment based on cable tension, improving construction accuracy. The cable tensioning process can be achieved by applying force through the first columns on both sides to tension and fix the second column. The entire structure is suitable for the construction of photovoltaic supports with general spans, balancing construction convenience and structural strength. Therefore, this invention provides a structure suitable for photovoltaic supports with different spans, allowing users to easily select the appropriate structure based on the span length.

[0024] 5. The construction method of the photovoltaic support system of the present invention includes the following steps: arranging multiple columns in a row on a foundation; connecting the cables to the top of the columns; tensioning the cables; and anchoring both ends of the cables to the foundation. This construction method only requires the combined construction of the columns and cables to complete the construction of the photovoltaic support system, simplifying the construction steps and shortening the construction time. Furthermore, the column configuration allows for more flexible construction and adaptability to various complex terrains (such as mountainous or hilly areas). The spacing between the columns can also be adjusted as needed, facilitating control of construction accuracy and demonstrating strong applicability.

[0025] 6. The construction method of the photovoltaic support system of the present invention includes tensioning the cables, comprising: performing a first tensioning on one or both ends of the cables, wherein the tension force of the first tensioning is less than a preset value; installing the photovoltaic modules onto the cables; and performing a second tensioning on one or both ends of the cables, wherein the tension force of the second tensioning reaches the preset value. In this scheme, the cables are tensioned in two stages. The first tensioning facilitates the initial formation of the photovoltaic support system structure. Then, the photovoltaic modules are installed onto the cables, and the cables are tensioned a second time to adjust the tension force to the preset value and the designed deformation state, thus completing the construction. Compared with single-stage tensioning, the two-stage tensioning of the cables in this embodiment facilitates the adjustment of structural offsets or deformations that occur during the later installation of photovoltaic modules, thereby improving the construction accuracy of the entire photovoltaic support system.

[0026] 7. In the construction method of the photovoltaic bracket of the present invention, the tension force of the first tensioning is 50% or 70% of the preset value. Specifically, when the bottom of all the columns is fixedly connected to the foundation or only the bottom of the second column is hinged to the foundation, the tension force of the first tensioning of the cable is 50% of the preset value, which can make the photovoltaic bracket stable in shape; when the bottom of all the columns is hinged to the foundation, that is, when all the columns are swing columns, the tension force of the first tensioning of the cable is 70% of the preset value, which makes it easier for the cable to provide sufficient tension force to make the photovoltaic bracket stable in shape.

[0027] 8. The construction method of the photovoltaic support system of the present invention involves arranging multiple columns in a row on a foundation, including the following steps: pouring the foundation, and fixing or hinged the bottom of the columns to the foundation. In this scheme, when the bottom of the column is fixed to the foundation, a rigid connection is achieved between the column and the foundation, which can ensure the connection rigidity and strength between the column and the foundation, thereby improving the structural strength of the entire photovoltaic support system and making it suitable for photovoltaic support systems with larger spans; when the bottom of the column is hinged to the foundation, the hinged connection replaces the rigid connection between the column and the foundation, which can simplify the construction steps and shorten the construction period and is suitable for photovoltaic support systems with smaller spans.

[0028] 9. The construction method of the photovoltaic support of the present invention involves arranging multiple columns in a row on a foundation, including the following steps: pouring the foundation, fixing the bottom of the first column to the foundation, hingedly connecting the bottom of the second column to the foundation, and positioning the second column between the first columns. In this scheme, the rigid connection between the bottom of the first column and the foundation provides a reference for the construction of the second column in the middle and a fulcrum for the tensioning of the cables. The hinged connection between the bottom of the second column and the foundation instead of a rigid connection simplifies construction, saves costs and time. The tensioning process of the cables can be achieved by providing force points through the first columns on both sides to tension and fix the second column. The entire structure is suitable for photovoltaic supports with medium to long spans, taking into account both construction convenience and structural strength.

[0029] 10. The construction method of the photovoltaic bracket of the present invention, which connects the cable to the top of the column, includes: when the bottom of the column is fixed to the foundation, the cable is hinged to the top of multiple columns to make the column vertically installed. At this time, after the bottom of the column is rigidly connected to the foundation, the column is vertically installed. After the cable is hinged to the top of the column, the column will not deform during the tensioning and deformation process of the cable, thereby ensuring the vertical installation accuracy of the entire column.

[0030] When the bottom of the column is hinged to the foundation, the top of the column is installed at an angle towards the end of the cable, and the cable is hinged to the tops of multiple columns. In this case, the bottom of the column is hinged to the foundation, meaning the column can swing with the cable during tensioning and deformation. Therefore, installing the top of the column at an angle towards the cable allows the column to swing to a vertical position when the cable is tensioned, thus improving the vertical installation accuracy of the column. Specifically, when the bottom of the column is hinged to the foundation, all columns are swing columns. The cable is tensioned at one end, and the top of the column is installed at an angle away from the tensioned end of the cable, allowing the column to swing to a vertical position when the cable is tensioned.

[0031] 11. The construction method of the photovoltaic support of the present invention connects the cable and the top of the column, including: when tensioning both ends of the cable, the second column located in the middle position is installed vertically, and the tops of the second columns on both sides are installed inclined towards the middle position. After tensioning both ends of the cable, the second columns on both sides located in the middle position swing to a vertical state following the deformation of the cable. In this scheme, because both ends of the cable are tensioned, the forces on both ends of the second column located in the middle position are balanced, thus maintaining a vertical installation state. The tops of the second columns on both sides are installed inclined towards the middle position. When tensioning both ends of the cable, the tension forces on the second columns on both sides are not equal. Therefore, the second columns on both sides located in the middle position will deform and swing to a vertical state following the end of the cable with a larger tension force. Thus, after the cable is tensioned, all the second columns are vertically installed, improving the installation accuracy.

[0032] When one end of the cable is tensioned, the top of the second column is installed at an angle away from the tensioning end of the cable. After tensioning one end of the cable is completed, the second column follows the deformation and swings to a vertical position. In this design, because one end of the cable is tensioned, the second column is subjected to tension at that end. The top of the second column is installed at an angle away from the tensioning end of the cable. When the tensioning end of the cable is tensioned, it causes the top of the second column to deform and swing towards the tensioning end of the cable, thereby causing the top of the second column to swing to a vertical position. After the cable tensioning is completed, all the second columns are installed vertically, ensuring installation accuracy. Attached Figure Description

[0051] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0053] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0054] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] like Figures 1 to 3 As shown, this embodiment discloses a photovoltaic support, including columns 1 and cables 2. Multiple columns 1 are provided and arranged in a row. Cables 2 are connected to multiple columns 1, and both ends of cables 2 are tensioned and anchored to the foundation 3. Cables 2 are suitable for supporting photovoltaic modules 10.

[0056] The photovoltaic support structure in this embodiment consists of columns 1 and cables 2. Multiple columns 1 are arranged in a row to form a support foundation 3. The cables 2 are connected to multiple columns 1, and both ends of the cables 2 are tensioned and anchored to the foundation 3. The cables 2 are suitable for supporting and connecting photovoltaic modules 10, so that the entire photovoltaic support structure is tensioned, forming a flexible support structure with good structural stability and toughness. Therefore, the overall structure of the photovoltaic support structure in this embodiment is simple. During construction, only the columns 1 and cables 2 need to be combined, which simplifies the construction steps, shortens the construction time, and reduces the project cost. In addition, the construction of the column 1 type is more flexible and can adapt to construction in various complex terrain scenarios (such as mountainous or hilly areas). The spacing of the columns 1 can also be adjusted as needed, making it highly applicable.

[0057] The photovoltaic bracket of this embodiment will be described in detail below with reference to the accompanying drawings.

[0058] In this embodiment, the support column 1 is a steel pipe or steel column, which has high structural strength and good reliability. In terms of arrangement, multiple support columns 1 can be arranged in rows to form a photovoltaic support of the required length. Furthermore, in order to improve the support stability of the photovoltaic module 10, at least two rows of support columns 1 are arranged, with at least two rows of support columns 1 arranged in parallel and spaced apart. The photovoltaic module 10 is supported by at least two rows of support columns 1 at the same time, resulting in higher stability and reliability.

[0059] In this embodiment, the cable 2 is hinged to the top of the multiple columns 1, allowing the cable 2 to rotate relative to the columns. Simultaneously, the cable 2 can also cause the columns 1 to move slightly during tensioning and deformation. Specifically, the cable 2 can be wound around the top of the columns 1, or the top of the columns 1 can have a hinge hole through which the cable 2 is wound and passes.

[0060] Optional, such as Figure 1 As shown, the bottom of column 1 can be fixedly connected to the foundation 3, and the top of column 1 is hinged to cable 2. In this scheme, the bottom of column 1 is rigidly connected to the foundation 3, ensuring the connection strength between column 1 and foundation 3. Column 1 will not deform when cable 2 is tensioned, thus ensuring the rigidity and strength of the entire photovoltaic support system. This system is suitable for photovoltaic support construction with a large span.

[0061] Optional, such as Figure 3 As shown, the bottom of column 1 can be hinged to foundation 3, allowing column 1 to swing along the tension direction of cable 2. The top of column 1 is hinged to cable 2. In this scheme, the hinged connection between column 1 and foundation 3 replaces the rigid connection, making construction simpler and more convenient. Furthermore, the tensioned anchorage of cable 2 at both ends to foundation 3 provides lateral stiffness, ensuring the structural strength of the photovoltaic support. This scheme is suitable for the construction of photovoltaic supports with smaller spans.

[0062] Optional, such as Figure 2 As shown, the column 1 includes a first column 11 and a second column 12. There are two first columns 11 arranged opposite each other. The bottom of the first column 11 is fixedly connected to the foundation 3. The second column 12 is located between the first columns 11. The bottom of the second column 12 is hinged to the foundation 3 so that the second column 12 can swing along the tension direction of the cable 2. The top of the first column 11 and the top of the second column 12 are both hinged to the cable 2. In this design, the bottom of the first column 11 is rigidly connected to the foundation 3, providing a fulcrum for the construction of the second column 12. The bottom of the second column 12 is hinged to the foundation 3 instead of rigidly connected, simplifying construction and saving costs and time. The second column 12 can swing along the tension direction of the cable 2, allowing it to adjust its position according to the tension of the cable 2, improving construction accuracy. The tensioning process of the cable 2 can be achieved by applying force through the first columns 11 on both sides to tension and fix the second column 12. The entire structure is suitable for the construction of photovoltaic supports with general spans, balancing construction convenience and structural strength. It can be understood that the span of this design falls between the spans of the first and second designs mentioned above.

[0063] Therefore, the above provides a structure for photovoltaic brackets suitable for different spans, which is very convenient for users to choose according to the span length.

[0064] It is understood that the above-mentioned fixed connection is that the bottom of column 1 / first column 11 extends into the foundation 3 and is welded and fixed, and the above-mentioned hinge connection is that the bottom of column 1 / second column 12 is hinged to the foundation 3 through a hinge seat.

[0065] This embodiment also discloses a construction method for a photovoltaic support system, including the following steps:

[0066] Multiple columns 1 are arranged in a row on the foundation 3;

[0067] Connect cable 2 to the top of column 1;

[0068] Tension cable 2;

[0069] Anchor both ends of cable 2 to foundation 3.

[0070] This construction method only requires the combined construction of column 1 and cable 2 to complete the construction of the photovoltaic support, which simplifies the construction steps and shortens the construction time. In addition, the construction of column 1 is more flexible and can adapt to construction in various complex terrain scenarios (such as mountainous or hilly areas). The spacing of column 1 can also be adjusted as needed, making it highly applicable.

[0071] like Figure 4 and Figure 13 As shown, optionally, multiple columns 1 are arranged in a row on the foundation 3, including the following steps: pouring the foundation 3; fixing or hinged the bottom of the column 1 to the foundation 3.

[0072] In this scheme, such as Figure 4 As shown, when the bottom of column 1 is fixed to foundation 3, a rigid connection is achieved between column 1 and foundation 3, ensuring the connection stiffness and strength between column 1 and foundation 3, thereby improving the structural strength of the entire photovoltaic support system and making it suitable for photovoltaic supports with larger spans; as Figure 13 As shown, when the bottom of column 1 is hinged to foundation 3, the hinged connection between column 1 and foundation 3 replaces the rigid connection, which simplifies the construction steps and shortens the construction cycle, and is suitable for photovoltaic brackets with smaller spans.

[0073] like Figures 7 to 9 As shown, in some embodiments, multiple columns 1 are arranged in a row on the foundation 3, including the following steps: pouring the foundation 3, fixing the bottom of the first column 11 in the column 1 to the foundation 3, hinge the bottom of the second column 12 in the column 1 to the foundation 3, and the second column 12 is located between the first columns 11.

[0074] In this scheme, the bottom of the first column 11 is rigidly connected to the foundation 3, which can provide a reference for the construction of the second column 12 in the middle and provide a fulcrum for the tensioning of the cable 2. The bottom of the second column 12 is hinged to the foundation 3 instead of rigidly connected, which can simplify construction and save costs and time. During the tensioning process of the cable 2, the first columns 11 on both sides can provide force points to tension and fix the second column 12. The whole structure is suitable for photovoltaic brackets with medium and long spans, taking into account both construction convenience and structural strength.

[0075] Specifically, such as Figure 5 As shown, connecting the cable 2 to the top of the column 1 includes: when the bottom of the column 1 is fixed to the foundation 3, hinge the cable 2 to the top of multiple columns 1, so that the column 1 is installed vertically. At this time, after the bottom of the column 1 is rigidly connected to the foundation 3, the column 1 is installed vertically. After the cable 2 is hinged to the top of the column 1, the column 1 will not deform during the tensioning and deformation process of the cable 2, thereby ensuring the vertical installation accuracy of the entire column 1.

[0076] like Figure 14 As shown, when the bottom of column 1 is hinged to foundation 3, the top of column 1 is installed at an angle towards the end of cable 2, and cable 2 is hinged to the tops of multiple columns 1. At this time, the bottom of column 1 is hinged to foundation 3, meaning that column 1 can swing with cable 2 during tensioning deformation. Therefore, installing the top of column 1 at an angle towards cable 2 allows cable 2 to swing column 1 to a vertical position when tensioned, thus improving the vertical installation accuracy of column 1. Specifically, when the bottom of column 1 is hinged to foundation 3, all columns 1 are swing columns. Cable 2 is tensioned at one end, and the top of column 1 is installed at an angle away from the tensioning end of cable 2, allowing cable 2 to swing column 1 to a vertical position when tensioned.

[0077] For example, the inclination of the top of column 1 is L1, L2, ... ...... Ln (where n is the number of columns 1), when one end of cable 2 is tensioned, the top of column 1 swings and displaces with cable 2 in the following order: -L1, -L2, ... ...... -Ln, thereby causing all columns 1 to swing to a vertical position, completing vertical construction with high precision.

[0078] In some embodiments, the cable 2 is connected to the top of the column 1, including: as follows Figure 9 and Figure 10As shown, when the two ends of the cable 2 are tensioned, the second column 12 located in the middle position is installed vertically, while the tops of the second columns 12 on both sides are installed at an angle towards the middle position. After the two ends of the cable 2 are tensioned, the second columns 12 on both sides in the middle position deform and swing to a vertical state along with the cable 2. In this scheme, since both ends of the cable 2 are tensioned, the second column 12 located in the middle position is balanced by forces at both ends and can maintain a vertical installation state. The tops of the second columns 12 on both sides are installed at an angle towards the middle position. When the two ends of the cable 2 are tensioned, the tension forces on the second columns 12 on both sides of the cable 2 are not equal. Therefore, the second columns 12 on both sides in the middle position will deform and swing to a vertical state along with the end of the cable 2 with a larger tension force. Thus, after the cable 2 is tensioned, all the second columns 12 are installed vertically, improving the installation accuracy.

[0079] For example, let the inclination of the tops of the second pillars 12 located on both sides of the middle position be X1, X2, ... ...... Xn (where n is the number of second columns 12 on both sides), when the two ends of the cable 2 are tensioned, the top of the second column 12 swings and displaces sequentially with the cable 2 as -X1, -X2, ... ...... -Xn, thereby swinging the second columns 12 on both sides to a vertical position, ensuring the vertical construction of the second columns 12 with high precision.

[0080] like Figure 9 and Figure 11 As shown, when one end of the cable 2 is tensioned, the top of the second column 12 is installed at an angle away from the tensioning end of the cable 2. After tensioning one end of the cable 2 is completed, the second column 12 follows the deformation and swing of the cable 2 to a vertical state. In this scheme, because one end of the cable 2 is tensioned, the second column 12 is subjected to tension force at one end. The top of the second column 12 is installed at an angle away from the tensioning end of the cable 2. When the tensioning end of the cable 2 is tensioned, it causes the top of the second column 12 to deform and swing towards the tensioning end of the cable 2, thereby causing the top of the second column 12 to swing to a vertical state. After the cable 2 is tensioned, all the second columns 12 are installed vertically, ensuring installation accuracy.

[0081] For example, let the inclination of the top of the second column 12 be Z1, Z2, ...... Zn (where n is the number of second columns 12), when one end of cable 2 is tensioned, the top of the second column 12 swings and displaces -Z1, -Z2, along with cable 2. ...... -Zn, thereby causing all the second columns 12 to swing to a vertical position, completing the vertical construction with high precision.

[0082] It should be noted that the tilt amounts Ln, Xn, and Zn in this embodiment are related to the length of the column 1, the diameter of the cable 2, etc. The elongation amounts Ln, Xn, and Zn can be calculated by variables or simulated in software. The specific calculation and simulation methods are well-known technologies in the field, and will not be described in detail in this embodiment.

[0083] like Figure 5 , Figure 6 , Figures 9 to 12 , Figure 14 , Figure 15 As shown, specifically, tensioning the cable 2 includes: performing a first tensioning on one or both ends of the cable 2, where the tension force of the first tensioning is less than a preset value; installing the photovoltaic module 10 on the cable 2; and performing a second tensioning on one or both ends of the cable 2, where the tension force of the second tensioning reaches the preset value.

[0084] In this scheme, the cable 2 is tensioned in two stages. The first tensioning facilitates the initial formation of the photovoltaic support structure. Then, the photovoltaic module 10 is installed on the cable 2. The cable 2 is then tensioned a second time to adjust the tension force to the preset value and the designed deformation state, thus completing the construction. Compared with single-stage tensioning, the two-stage tensioning of the cable 2 in this embodiment facilitates the adjustment of structural offsets or deformations that may occur during the later installation of the photovoltaic module 10, thereby improving the construction accuracy of the entire photovoltaic support.

[0085] Furthermore, the initial tension force is 50% or 70% of the preset value. Specifically, for example... Figure 5 , Figure 6 , Figures 9 to 12 As shown, when the bottom of all columns 1 are fixedly connected to the foundation 3, or only the bottom of the second column 12 is hinged to the foundation 3, the tension force of the first tensioning of the cable 2 is 50% of the preset value, which can stably shape the photovoltaic support; Figure 14 and Figure 15 As shown, when the bottom of each column 1 is hinged to the foundation 3, that is, each column 1 is a swing column, the tension force of the first tensioning of the cable 2 is 70% of the preset value, so that the cable 2 can provide sufficient tension force to make the photovoltaic bracket stable and formed.

[0086] Anchor both ends of cable 2 to foundation 3. Specifically, as follows: Figure 6 , Figure 12 and Figure 15 As shown, after the cable 2 is tensioned, both ends of the cable 2 are anchored to the foundation 3 to achieve fixation and ensure the structural stability of the entire photovoltaic support.

[0087] It should be noted that the foundation 3 in this embodiment can be the ground or a separately poured concrete layer.

[0088] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
