Description

Technical Field

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

[0002] A photovoltaic system is a power generation system that uses the photovoltaic effect of solar energy to convert solar energy into electrical energy. By installing photovoltaic panels above fish ponds and continuing aquaculture in the water below, a three-dimensional and comprehensive utilization of land resources is achieved. Without increasing land occupation, the dual benefits of photovoltaic power generation and aquaculture are obtained at the same time, which greatly improves the economic value per unit area of ​​land.

[0003] In practical applications of solar-aquaculture hybrid projects, traditional flexible photovoltaic (PAC) support end anchoring structures are ill-suited to the stringent requirements of complex geological conditions and large spans. In some large-scale PAC projects, vast water areas necessitate the installation of extensive flexible PAC supports to achieve efficient power generation. However, due to poor geological conditions and limited resistance to horizontal loads, the ends of the PAC supports frequently experience displacement, tilting, or even collapse during severe weather conditions such as strong winds. This not only severely disrupts the normal operation of the PAC power station, significantly reducing power generation efficiency, but also risks equipment damage, resulting in high maintenance costs and economic losses. Therefore, a flexible PAC support end anchoring structure is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a flexible photovoltaic support end anchoring structure, which aims to improve the problem in the existing technology where, due to poor geological conditions, the pile body has limited ability to resist horizontal loads, and the photovoltaic support end frequently experiences displacement, tilting, or even collapse when encountering strong winds and other severe weather. This not only seriously interferes with the normal operation of the photovoltaic power station, causing a significant reduction in power generation efficiency, but may also cause equipment damage, resulting in high maintenance costs and economic losses.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Reference Figure 1 and Figure 2This utility model provides an embodiment of a flexible photovoltaic support end anchoring structure, comprising multiple first foundation columns 1, second foundation columns 11, and support columns 4. The first foundation columns 1, second foundation columns 11, and support columns 4 form the basic support structure for the entire anchoring structure, supporting the flexible photovoltaic support. A first connecting steel beam 3 is fixedly connected between the tops of the first foundation columns 1 and the support columns 4. The first connecting steel beam 3 effectively and securely connects the first foundation columns 1 and the support columns 4, providing basic lateral support for the entire anchoring structure. This makes the connection between the two more robust, ensuring that the structure will not shift or be damaged due to weak connections when subjected to external wind, gravity, or other loads. A third connecting steel beam 12 is fixedly connected between the tops of the second foundation columns 11 and the support columns 4. The third connecting steel beam 12 further... The stability of the supporting column 4 and the other foundation column, namely the second foundation column 11, is enhanced, thereby improving the lateral stability of the structure from another direction. This allows the entire support to maintain balance under complex stress conditions. A second reinforcing steel beam 13 is fixedly connected between the top of the first foundation column 1 and the second foundation column 11. The second reinforcing steel beam 13 directly connects the two foundation columns, forming one side of a stable triangular structure, which greatly improves the collaborative load-bearing capacity between the two foundation columns. The side of the second foundation column 11 away from the supporting column 4 is fixedly connected to the first supplementary column 2 through the second connecting steel beam 6. The first supplementary column 2 extends the coverage of the structure and provides an additional support point for the second foundation column 11 in the direction away from the supporting column 4, dispersing the stress acting on the second foundation column 11 and improving the load-bearing capacity of the entire structure in this area.A second auxiliary column 15 is fixedly connected to the side of the first foundation column 1 away from the supporting column 4 via a fourth connecting steel beam 14. The second auxiliary column 15 serves the same purpose as the first auxiliary column 2, providing additional support to the first foundation column 1 in the direction away from the supporting column 4, enhancing the stability of the structure on that side, and making the stress distribution of the entire anchoring structure more balanced in different directions. A second connecting cable base 9 is fixedly connected to the top of the second connecting steel beam 6 along its length. The function of the second connecting cable base 9 is to provide an installation foundation for the connecting cable. By connecting the cable to other parts, the tensile strength of the structure in this area can be further enhanced, preventing structural deformation or damage due to external tensile forces. The top of the fourth connecting steel beam 14 is fixedly connected to the first connecting cable base 8, which also provides a foundation for cable connection and enhances the tensile performance of the structure from another direction. Working in conjunction with the second connecting cable base 9, it improves the overall structure's ability to resist tensile forces in different directions. The top of the supporting column 4 is fixedly connected along its length to the supporting cable base 5, which provides an installation position for the supporting cables. Connected to other structural components via cables, it enhances the stability of the supporting column 4 in different directions, shares some of the load borne by the supporting column 4, and ensures that the supporting column 4 can still stably support the entire support structure under complex stress conditions. A first reinforcing steel beam 7 is fixedly connected between the first supplementary column 2 and the second supplementary column 15. The first reinforcing steel beam 7 connects the two supplementary columns, forming a relatively independent and stable structure, further enhancing the stability of the entire anchoring structure in the supplementary column area, improving the structure's ability to withstand external loads, and reducing the possibility of the supplementary column tilting or displacing due to individual stress.

[0027] Reference Figure 1 and Figure 2 The tops of the first connecting cable base 8, the second connecting cable base 9, and the supporting cable base 5 are all bolted with steel cables 10. The bolted connection ensures that the steel cables 10 and the base have sufficient connection strength, ensuring that the steel cables 10 will not easily fall off when subjected to tension, effectively playing their role in enhancing the tensile performance of the structure. Through the connection of the steel cables 10 with different bases, tension can be applied to the anchoring structure from multiple directions, balancing the external forces borne by the structure in different directions, and improving the stability of the entire flexible photovoltaic bracket end anchoring structure.

[0028] Reference Figure 1 and Figure 2The second connecting steel beam 6, the first reinforcing steel beam 7, the third connecting steel beam 12, and the fourth connecting steel beam 14 between the first foundation column 1, the first supplementary column 2, the second foundation column 11, and the second supplementary column 15 are arranged in a parallelogram shape. While the parallelogram structure possesses a degree of deformability, it effectively disperses and transmits forces when working in conjunction with other structural components. In this anchoring structure, when subjected to external loads, the force can be transmitted and dispersed among the four columns through the parallelogram-shaped steel beams, preventing any single column from being damaged by excessive concentrated force. Furthermore, the parallelogram distribution ensures relatively balanced stress distribution in different directions, enhancing the overall stability of the structure.

[0029] Reference Figure 1 and Figure 2 The first connecting steel beam 3, the third connecting steel beam 12, and the second reinforcing steel beam 13 between the first foundation column 1, the supporting column 4, and the second foundation column 11 are arranged in an oblique triangle. Triangles provide stability and are less prone to deformation. The oblique triangle formed by the first connecting steel beam 3, the third connecting steel beam 12, and the second reinforcing steel beam 13 tightly connects the three columns, greatly enhancing the overall stability of the structure. When the structure is subjected to various external forces, the oblique triangle structure can effectively decompose and transfer the external forces to each column, enabling the entire structure to better withstand pressure, tension, and shear forces.

[0030] Reference Figure 1 and Figure 2 The supporting cable base 5, the second connecting cable base 9, and the first connecting cable base 8 are arranged in a diagonal triangle. This diagonal triangular design ensures good stability of the cable structure formed by the connection of the steel cables 10. The diagonal triangular structure can apply tensile force to the anchoring structure from multiple directions, balancing the external forces borne by the structure. When the structure is subjected to external loads, the cables can transmit the force in different directions, avoiding force concentration.

[0031] Reference Figure 1 and Figure 2 The first connecting steel beam 3, the second connecting steel beam 6, the first reinforcing steel beam 7, the third connecting steel beam 12, the second reinforcing steel beam 13, and the fourth connecting steel beam 14 are all H-shaped. The flanges of the H-shaped steel beams can effectively resist bending stress, while the web mainly bears shear force. When the steel beam is subjected to external loads, the H-shaped structural design allows the steel beam to fully utilize its mechanical properties, distributing the force evenly across the entire steel beam cross-section and avoiding localized stress concentration.

[0032] Reference Figure 1 and Figure 2The first connecting steel beam 3, the second connecting steel beam 6, the first reinforcing steel beam 7, the third connecting steel beam 12, the fourth connecting steel beam 14, and the second reinforcing steel beam 13 are all fixed to the first foundation column 1, the first supplementary column 2, the supporting column 4, the second foundation column 11, and the second supplementary column 15 by welding. The welding forms a unified whole between the steel beams and columns, effectively transferring force. When subjected to external loads, the welded connections ensure smooth force transmission between the steel beams and columns, preventing structural deformation or damage caused by loose connections.

[0033] Working principle: First, the basic columns and supplementary columns are constructed to form the basic structure through corresponding connecting steel beams. The first basic column 1 and the supporting column 4 are connected by the first connecting steel beam 3, the second basic column 11 and the supporting column 4 are connected by the third connecting steel beam 12, and the first basic column 1 and the second basic column 11 are connected by the second reinforcing steel beam 13. This oblique triangular distribution of steel beams initially stabilizes the position of the three main columns and bears some vertical and horizontal forces from the structure itself and from the outside.

[0034] Next, the first supplementary column 2 is connected to the second foundation column 11 through the second connecting steel beam 6, and the second supplementary column 15 is connected to the first foundation column 1 through the fourth connecting steel beam 14. The first supplementary column 2 and the second supplementary column 15 are fixed together by the first reinforcing steel beam 7. This part of the parallelogram-shaped steel beam connection further expands the support range of the structure, disperses the force borne by the foundation column, and enhances the stability of the structure in all directions.

[0035] Then, the support cable base 5, the second connecting cable base 9, and the first connecting cable base 8 are fixed to the support column 4, the second connecting steel beam 6, and the fourth connecting steel beam 14, respectively, and steel cables 10 are installed on these bases by bolts. When the structure is subjected to external loads, such as wind force and gravity, the force will first act on the entire anchoring structure. The parallelogram-distributed steel beam structure will transfer and disperse the force between the first foundation column 1, the first supplementary column 2, the second foundation column 11, and the second supplementary column 15. The obliquely triangularly distributed steel beam structure will further decompose the force to the first foundation column 1, the support column 4, and the second foundation column 11. The obliquely triangularly distributed cable bases and the connected steel cables 10 will apply tension to the structure from multiple directions, balancing the external forces borne by the structure, resisting the displacement and deformation of the structure, transferring the force to different directions, reducing the pressure on the columns and steel beams, and ensuring that the entire flexible photovoltaic support end anchoring structure can operate stably and withstand various complex external loads.
