[0036] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0037] The following is for reference. Figure 1 and Figure 3 The photovoltaic support device 100 according to this application is used for fixed installation on a foundation. The photovoltaic support device 100 includes: a concrete base 10, at least a portion of which is adapted to be buried in the foundation, and the concrete base 10 is used to install the structure to be installed; and a fixing pile 20, which is located on one side of the concrete base 10 and extends along the arrangement direction of the concrete base 10 and the fixing pile 20. The height of the end face of the fixing pile 20 facing the concrete base 10 is lower than the height of the end face of the concrete base 10 facing the fixing pile 20. The fixing pile 20 abuts against the concrete base 10 and is fixed to the concrete base 10. The fixing pile 20 is adapted to be buried in the foundation.

[0038] The photovoltaic support device 100 is used for fixed installation on the foundation, which can significantly improve the structural stability of the entire photovoltaic system. It can be noted that the foundation can be the ground (desert, grassland, tidal flat), roof (residential, commercial roof), building facade (photovoltaic curtain wall), etc.

[0039] like Figure 1 As shown, the photovoltaic support device 100 includes a concrete base 10, at least a portion of which is adapted to be embedded in the foundation. In some embodiments of this application, one-half, one-third, or equal proportions of the concrete base 10 are adapted to be embedded in the foundation, or the entire concrete base 10 may be embedded in the foundation, as long as at least a portion of the concrete base 10 is adapted to be embedded in the foundation. The concrete base 10 is used to install the structure to be installed, which may be the column base plate or the base plate of the inclined tie member of the photovoltaic support. As the main load-bearing part of the photovoltaic support, the embedding of the concrete base 10 in the foundation can significantly increase the contact area between the photovoltaic support and the foundation, thereby significantly improving the overall stability of the photovoltaic support. The concrete base 10 has high strength and durability, and can resist various corrosive factors in the natural environment, such as rainwater erosion and weathering, extending the service life of the photovoltaic support.

[0040] The fixing pile 20 is located on one side of the concrete base 10 and extends along the arrangement direction of the concrete base 10 and the fixing pile 20. The fixing pile 20 being located on one side of the concrete base 10 means that the fixing pile 20 is located on the side of the concrete base 10 away from the structure to be installed. The height of the end face of the fixing pile 20 facing the concrete base 10 is lower than the height of the end face of the concrete base 10 facing the fixing pile 20. The fixing pile 20 and the concrete base 10 abut against each other and the fixing pile 20 is fixed to the concrete base 10. This allows the fixing pile 20 to extend obliquely or vertically along the arrangement direction of the concrete base 10 and the fixing pile 20 (the vertical direction based on the ground). This layout can significantly enhance the overall structural stability of the photovoltaic support device 100 and eliminate the need for the fixing pile 20 to extend into the concrete base 10, reducing the length of the fixing pile 20, saving manufacturing costs for the fixing pile 20 and the concrete base 10, and also reducing transportation difficulties.

[0041] The fixing pile 20 abuts against the concrete base 10, and the fixing pile 20 is fixed to the concrete base 10. In some embodiments of this application, the fixing pile 20 and the concrete base 10 can be fixedly connected by bolts, or the fixing pile 20 and the concrete base 10 can be fixedly connected by concrete pouring. However, this utility model is not limited to these; as long as the fixing pile 20 is fixed to the concrete base 10, it is acceptable. The fixing pile 20 abuts against and is fixed to the concrete base 10, forming a reliable support structure, improving the horizontal resistance of the fixing pile 20, and further enhancing the overturning resistance of the photovoltaic support. The fixing pile 20 is buried in the foundation, which can penetrate deep into the soil layer and use the bearing capacity of the soil layer to stabilize the photovoltaic support device 100, ensuring that the photovoltaic support device 100 can maintain a stable operating state under various climatic conditions, thereby improving the stability and durability of the photovoltaic support device 100.

[0042] The design of the concrete base 10 and the fixing piles 20 can adapt to various foundation conditions, such as flat land, mountains, and water bodies, demonstrating strong environmental adaptability. By adjusting parameters such as the size, shape, and burial depth of the concrete base 10 and the fixing piles 20, installation requirements under different terrain and climatic conditions can be met. The photovoltaic support device 100 can be customized according to the specific project requirements, such as adjusting the height, angle, and layout of the photovoltaic support device 100 to adapt to different application scenarios and power generation needs, thereby improving the geological applicability of the photovoltaic support device 100.

[0043] Furthermore, the concrete base 10 and fixing piles 20 have relatively simple structures. Both the concrete base 10 and fixing piles 20 can be fully or partially prefabricated in the factory, avoiding or reducing on-site concrete pouring. They can be directly assembled and used on-site, making the construction process easier to control and reducing the construction difficulty and time cost of the photovoltaic support device 100. Specifically, standardized concrete bases 10 and fixing piles 20 can be used to achieve rapid installation and dismantling, improving construction efficiency. The material cost of the concrete base 10 and fixing piles 20 is relatively low and readily available, reducing the overall cost of the photovoltaic support device 100. Due to its stable structure and high durability, the cost of later maintenance and replacement is reduced, improving the economic efficiency of the photovoltaic support device 100.

[0044] According to the photovoltaic support device 100 of this application, at least a portion of the concrete base is buried in the foundation. The concrete base 10 is used to install the structure to be installed. The fixing pile 20 is located on one side of the concrete base 10 and extends along the arrangement direction of the concrete base 10 and the fixing pile 20. The height of the end face of the fixing pile 20 facing the concrete base 10 is lower than the height of the end face of the concrete base 10 facing the fixing pile 20. The fixing pile 20 and the concrete base 10 abut against each other and the fixing pile 20 is fixed to the concrete base 10. The fixing pile 20 is suitable for being buried in the foundation, eliminating the need for on-site concrete pouring, reducing the curing time of the concrete, and improving the horizontal resistance of the fixing pile 20. This can improve the stability and durability of the photovoltaic support device 100, thereby improving the geological applicability of the photovoltaic support device 100. Furthermore, the structure of the concrete base 10 and the fixing pile 20 is simple, the manufacturing cost is low, the construction process is easy to control, and the construction difficulty and time cost are reduced.

[0045] According to one embodiment of this application, such as Figure 5 As shown, the photovoltaic support device 100 also includes a connecting mechanism 30, which is used to connect the concrete base 10 and the fixing pile 20 so that the fixing pile 20 is detachably fixed to the concrete base 10.

[0046] The connecting mechanism 30 may include nuts, screws, clips, slots, pins, etc., as long as it can connect the concrete base 10 and the fixing piles 20. The connecting mechanism 30 connects the concrete base 10 and the fixing piles 20, allowing the fixing piles 20 to be detachably fixed to the concrete base 10, thus improving the installation flexibility of the photovoltaic support device 100. In practical applications, the position and number of fixing piles 20 can be flexibly adjusted according to the specific site conditions and the layout requirements of the photovoltaic support. Furthermore, when it is necessary to move or reinstall the photovoltaic support, the concrete base 10 and the fixing piles 20 can be easily disassembled and reassembled, reducing the difficulty and cost of installation and disassembly.

[0047] Furthermore, it facilitates the maintenance and replacement of the photovoltaic support device 100, which not only extends the service life of the photovoltaic support device 100, but also ensures that it always maintains a good working condition, thereby improving the overall efficiency of the photovoltaic power generation system.

[0048] According to one embodiment of this application, such as Figure 5 As shown, the connecting mechanism 30 may include a connecting rod 31 and a first limiting part 32. The end of the fixed pile 20 facing the concrete base 10 has a mounting plate 21, the mounting plate 21 abuts against the concrete base 10, the connecting rod 31 passes through the concrete base 10 and the mounting plate 21 along the arrangement direction of the concrete base 10 and the fixed pile 20, and the first limiting part 32 is located on the side of the mounting plate 21 away from the concrete base 10. The first limiting part 32 is detachably connected to the connecting rod 31 and is adapted to abut against the mounting plate 21.

[0049] The fixed pile 20 has a mounting plate 21 at the end facing the concrete base 10. In some embodiments of this application, the fixed pile 20 and the mounting plate 21 can be fixedly connected by welding or by bolts. However, this utility model is not limited to this. The fixed pile 20 and the mounting plate 21 can also be fixedly connected by other means, as long as the end of the fixed pile 20 facing the concrete base 10 has a mounting plate 21.

[0050] The mounting plate 21 abuts against the concrete base 10, and the connecting rod 31 passes between the concrete base 10 and the fixed pile 20 along the arrangement direction of the two, making the connection between the fixed pile 20 and the concrete base 10 tighter and stronger, which helps to resist external loads and deformation. The first limiting part 32 is located on the side of the mounting plate 21 away from the concrete base 10. The first limiting part 32 is detachably connected to the connecting rod 31 and is suitable for abutting against the mounting plate 21, which plays a limiting role and to a certain extent prevents the fixed pile 20 from shifting or tilting after installation, thereby ensuring the stability of the entire structure. Through the cooperation of the connecting rod 31 and the first limiting part 32, the fixed pile 20 can be installed quickly. During the installation process, it is only necessary to pass the connecting rod 31 between the concrete base 10 and the mounting plate 21 and connect the first limiting part 32 to the connecting rod 31, which simplifies the installation steps and improves the installation efficiency. When it is necessary to disassemble the fixed pile 20, it is only necessary to remove the connection between the first limiting part 32 and the connecting rod 31, which makes the disassembly process simpler and faster, and reduces disassembly time and cost.

[0051] Furthermore, since the first limiting part 32 is detachable, it can be adjusted and corrected according to the actual situation during installation, improving the flexibility and accuracy of installation and helping to ensure the correct installation position of the fixing pile 20. The design of the connecting mechanism 30 simplifies the installation and disassembly process, reducing labor and material costs. At the same time, since the connecting rod 31 and the first limiting part 32 are reusable, material costs are also reduced.

[0052] It can be explained that the connecting rod 31 can be constructed as a screw, and the first limiting part 32 can be constructed as a nut. The screw, as a fastener with external threads, cooperates with the nut, which has internal threads, to achieve a tight connection and fixation. In the photovoltaic support device 100, the screw, as the connecting rod 31, passes through the concrete base 10 and the mounting plate 21 of the fixed pile 20, while the nut, as the first limiting part 32, is tightened onto the screw and abuts against the mounting plate 21, thereby achieving a stable connection between the concrete base 10 and the fixed pile 20. Since screws and nuts are common fasteners, their procurement or processing costs are relatively low. At the same time, because the installation and disassembly process is simple and quick, it also reduces labor and material costs.

[0053] According to one embodiment of this application, such as Figure 5 As shown, the mounting plate 21 may have mounting holes 22, and the connecting rod 31 passes through the mounting holes 22.

[0054] The shape and size of the mounting hole 22 can match the shape and size of the connecting rod 31, allowing the connecting rod 31 to pass smoothly through the mounting hole 22. This enables a stable connection between the concrete base 10 and the fixed pile 20 without the need for additional force or tools, thus simplifying the installation process. Furthermore, pre-processing the mounting hole 22 on the mounting plate 21 avoids the need for drilling during installation, reducing the risk of drilling errors, protecting the structural integrity of the mounting plate 21, and improving installation efficiency and quality.

[0055] According to one embodiment of this application, such as Figure 4 and Figure 5 As shown, the connecting mechanism 30 may further include: a fixing plate 33, which is located on the side of the concrete base 10 away from the fixing pile 20 and abuts against the concrete base 10; a connecting rod 31 is also inserted through the fixing plate 33; one end of the connecting rod 31 has a second limiting part 34, which is located on the side of the fixing plate 33 away from the concrete base 10 and abuts against the fixing plate 33.

[0056] The connection between the fixing plate 33 and the concrete base 10, the connecting rod 31 passing through the fixing plate 33, and the second limiting part 34 abutting against the fixing plate 33 form a double-fixed structure, which greatly enhances the stability of the connecting mechanism 30. Due to the presence of the fixing plate 33 and the second limiting part 34, the connecting rod 31 is not easy to loosen or shift when subjected to force, thereby reducing the safety hazards caused by loosening. This makes the connection between the fixed pile 20 and the concrete base 10 more solid. In addition, the fixing plate 33 can also distribute the load borne by the connecting rod 31 to a larger area, thereby reducing the stress concentration per unit area and improving the load-bearing capacity of the entire connecting mechanism 30.

[0057] The tight connection between the fixing plate 33 and the concrete base 10 further enhances the overall structural strength, making the photovoltaic support device 100 more stable and reliable when bearing external loads. Furthermore, the installation steps of the connecting mechanism 30 remain relatively simple; the connecting rod 31 is simply passed sequentially through the mounting plate 21, the concrete base 10, and the fixing plate 33, and then the first limiting part 32 and the second limiting part 34 are fixed. This improves installation efficiency and reduces installation costs.

[0058] According to one embodiment of this application, the fixing plate 33 is fixed to the concrete base 10. In some embodiments of this application, the fixing plate 33 can be pre-embedded in the concrete base 10, or it can be fixed to the concrete base 10 and the fixing plate 33 by means of a connecting rod 31 extending along the extension direction of the concrete base 10 and the fixing plate 33, and then the fixing plate 33 is fixed to the concrete base 10 by the second limiting part 34. However, this utility model is not limited to this. The fixing plate 33 and the concrete base 10 can also be fixedly connected by other means, as long as the fixing plate 33 is fixed to the concrete base 10. Pre-embedding the fixing plate 33 or fixing it on site by means of connecting rod 31 can simplify the construction steps to a certain extent. Pre-embedding can reduce the complexity of on-site construction, while means of connecting rod 31 facilitates quick installation and adjustment. The fixing plate 33 is fixed to the concrete base 10, making the photovoltaic support device 100 more stable when subjected to external forces, reducing safety hazards caused by structural instability.

[0059] According to one embodiment of this application, such as Figure 6 , Figure 7 , Figure 8As shown, the fixing plate 33 has at least one through hole 35. In some embodiments of this application, the fixing plate 33 may have one, two, three, or other numbers of through holes 35, but this utility model is not limited to this. The fixing plate 33 may also have other numbers of through holes 35, as long as the fixing plate 33 has at least one through hole 35. Furthermore, the number of through holes 35 in the fixing plate 33 may be greater than or equal to the number of connecting rods 31. Some of the through holes 35 may be used to install the connecting rods 31, and some of the through holes 35 may be used to pour concrete, further strengthening the connection between the fixing plate 33 and the concrete base 10. This can further enhance the strength of the overall structure, making the photovoltaic support device 100 more stable and reliable when bearing external loads.

[0060] Furthermore, the number of through holes 35 in the fixing plate 33 can be reasonably set according to actual conditions. In the first embodiment of the fixing plate 33 of this application, for example... Figure 6 As shown, the fixing plate 33 can be constructed as a circle, and the fixing plate 33 can form thirteen through holes 35. A circular central through hole 351 is formed at the center of the fixing plate 33. Four rows of through holes 35 are evenly arranged along the circumference of the central through hole 351. Each row has three through holes 35, and each row of through holes 35 is arranged along the diameter of the fixing plate 33. Each row of three through holes 35 has two strip through holes 352 and one circular through hole 353. The circular through hole 353 is arranged between the two strip through holes 352.

[0061] Alternatively, in the second embodiment of the fixing plate 33 of this application, such as Figure 7 As shown, the fixing plate 33 can be constructed as a circle, and the fixing plate 33 can form nine through holes 35. A circular central through hole 351 is formed at the center of the fixing plate 33. Eight through holes 35 are evenly arranged along the circumference of the central through hole 351. Among the eight through holes 35, there are two circular first through holes 354, four circular second through holes 355, and two strip through holes 352. The two first through holes 354 and the two strip through holes 352 are symmetrically arranged on both sides of the central through hole 351 along the diameter extension direction of the central through hole 351, and a second through hole 355 is arranged between each adjacent first through hole 354 and strip through hole 352.

[0062] Alternatively, in the third embodiment of the fixing plate 33 of this application, such as Figure 8 As shown, the fixing plate 33 can be constructed as a circle, and the fixing plate 33 can form four through holes 35 of the same shape and size. The four through holes 35 are evenly arranged on the fixing plate 33, the center point of each through hole 35 is equidistant from the center point of the fixing plate 33, and the center point of each through hole 35 is equidistant from the edge of the fixing plate 33.

[0063] According to one embodiment of this application, such as Figure 1 and Figure 3 As shown, along the arrangement direction of the concrete base 10 and the fixing piles 20, the surface of the fixing plate 33 facing away from the fixing piles 20 and the surface of the concrete base 10 facing away from the fixing piles 20 are coplanar. This makes the entire structure more uniformly stressed, which helps to enhance the overall stability of the structure and reduces the risk of structural deformation or damage caused by uneven stress. Furthermore, the coplanar design makes the connection between the fixing plate 33 and the concrete base 10 tighter, reducing adjustment work during construction. In a limited space, the coplanar design maximizes the use of space and reduces unnecessary waste.

[0064] Furthermore, when processing the photovoltaic support device 100, the connecting rod 31 can be directly embedded into the concrete base 10 for integral casting. The integral casting method can form a tight bond between the connecting rod 31 and the concrete base 10, improving the stability and load-bearing capacity of the entire structure. At this time, the fixing plate 33 and the second limiting part 34 can be eliminated, and the connecting rod 31 can be directly inserted into the mounting plate 21 and the mounting plate 21 and the concrete base 10 can be fixedly connected through the first limiting part 32. This simplifies the entire installation process, improves construction efficiency, and reduces costs.

[0065] Alternatively, corresponding through holes 35 can be formed in both the concrete base 10 and the fixing plate 33, and the connecting rod 31 can be sequentially inserted into the mounting plate 21, the concrete base 10, and the fixing plate 33. Then, the fixing plate 33, the concrete base 10, and the fixing pile 20 can be fixedly connected through the first limiting part 32 and the second limiting part 34, which provides greater flexibility, can be adjusted according to actual needs, and is also convenient for maintenance.

[0066] When the concrete base 10 has reserved through holes 35, the number of through holes 35 can be the same as the number of connecting rods 31, and each through hole 35 corresponds one-to-one with each connecting rod 31. Alternatively, the number of through holes 35 can be less than the number of connecting rods 31, with some through holes 35 used to accommodate multiple connecting rods 31. Or, the concrete base 10 can reserve only one through hole 35 to accommodate all connecting rods 31. After the connecting rods 31 are installed, the through holes 35 are filled with concrete or cement mortar to make the connecting rods 31 more firmly fixed to the concrete base 10, thereby improving the stability and reliability of the entire photovoltaic support device 100.

[0067] According to one embodiment of this application, such as Figure 5 As shown, there can be multiple connecting rods 31 and multiple first limiting parts 32, with each connecting rod 31 corresponding to a different first limiting part 32.

[0068] There can be multiple connecting rods 31 and first limiting parts 32. In some embodiments of this application, there can be two, three, four or other numbers of connecting rods 31 and first limiting parts 32. However, this utility model is not limited to this. There can also be other numbers of connecting rods 31 and first limiting parts 32, as long as there are multiple connecting rods 31 and first limiting parts 32.

[0069] By using multiple connecting rods 31 and first limiting parts 32, the connection strength between the fixed pile 20 and the concrete base 10 can be enhanced, improving the overall structural stability. The multiple connecting rods 31 and first limiting parts 32 can also accommodate fixed piles 20 and concrete bases 10 of different sizes, increasing design flexibility and versatility. The one-to-one correspondence between multiple connecting rods 31 and multiple first limiting parts 32 provides more positioning points, facilitating more accurate positioning during installation and ensuring installation precision. It also provides additional safety redundancy; even if a limiting point malfunctions, it will not seriously affect the entire structure, effectively reducing safety hazards caused by loosening or detachment of the photovoltaic support device 100 during long-term use. This significantly improves the structural stability, installation accuracy, adaptability, and safety of the photovoltaic support device 100.

[0070] According to one embodiment of this application, such as Figure 1 As shown, there can be multiple fixed piles 20 and multiple connecting mechanisms 30, with each fixed pile 20 and connecting mechanism 30 corresponding to the other.

[0071] In this application, there can be multiple fixed piles 20 and connecting mechanisms 30. In some embodiments, there can be two, three, four, or other numbers of fixed piles 20 and connecting mechanisms 30. However, this invention is not limited to this and other numbers of fixed piles 20 and connecting mechanisms 30 are also possible, as long as there are multiple fixed piles 20 and connecting mechanisms 30. The arrangement of multiple fixed piles 20 and connecting mechanisms 30 can more effectively distribute the load borne by the photovoltaic support device 100, avoid structural damage or deformation caused by excessive force at a single point, significantly improve the overturning resistance of the photovoltaic support device 100, and to a certain extent avoid structural overturning or collapse caused by external forces, thereby improving the stability and safety of the photovoltaic support device 100.

[0072] Multiple fixed piles 20 and multiple connecting mechanisms 30 are set one-to-one, so that each fixed pile 20 is connected to the concrete base 10 through an independent connecting mechanism 30. The multi-point connection method greatly enhances the strength and reliability of the connection. Even if a problem occurs at one connection point, the other connection points can still maintain the stability of the structure.

[0073] According to one embodiment of this application, such as Figure 1 and Figure 3As shown, the concrete base 10 may have a pre-embedded connector 40, which is used to install the structure to be installed.

[0074] The concrete base 10 may contain embedded connectors 40. These connectors 40 are integrated with the concrete structure through concrete pouring, reducing maintenance workload caused by loosening, detachment, or damage to the connectors. This also simplifies subsequent installation. The embedded connectors 40 are used to install the structure to be installed; simply fix the structure using the embedded connectors 40, eliminating the need for complex drilling or jacking on-site. It can be noted that the structure to be installed can be the base plate of a photovoltaic support column or the base plate of a tie rod.

[0075] The position and dimensions of the embedded connector 40 are determined before concrete pouring and are precisely measured and positioned. Therefore, using the embedded connector 40 for installation ensures the positional and dimensional accuracy of the structure to be installed, meeting design requirements. The embedded connector 40 can also distribute the load borne by the structure to be installed into the concrete base 10, thereby reducing the risk of single-point stress, helping to disperse and balance stress in the structure, and reducing the risk of structural failure due to excessive load.

[0076] Furthermore, the shape of the pre-embedded connector 40 can be reasonably set according to the actual situation, as shown in some embodiments of this application.

[0077] As a first embodiment of the pre-embedded connector 40 provided in this application, the pre-embedded connector 40 can be... Figure 9Specifically, the pre-embedded connector 40 may include a first plate 41, a second plate 42, a third plate 43, and a fourth plate 44. The third plate 43 and the fourth plate 44 are both located on the same side of the first plate 41, and the third plate 43 and the fourth plate 44 are both fixedly connected to the first plate 41. The third plate 43 and the fourth plate 44 can be constructed with the same structure. The third plate 43 and the fourth plate 44 are arranged opposite to each other and spaced apart. Each of the third plate 43 and the fourth plate 44 can include a first connecting plate 1 and a second connecting plate 2. The corresponding first connecting plate 1 and the corresponding second connecting plate 2 are perpendicularly connected and connected by an arc-shaped connecting part. The first connecting plate 1 of the third plate 43 and the first connecting plate 1 of the fourth plate 44 are parallel and spaced apart. The second connecting plate 2 of the third plate 43 and the second connecting plate 2 of the fourth plate 44 are coplanar. The second plate 42 is connected between the first connecting plate 1 of the third plate 43 and the first connecting plate 1 of the fourth plate 44. The second plate 42 is parallel to the first plate 41 and spaced apart. Through the combination of the first plate 41, the second plate 42, the third plate 43 and the fourth plate 44, a multi-connection structure is formed, which enables the embedded connector 40 to enhance the stability and strength of the overall structure. Meanwhile, the arc-shaped connection can increase the flexibility of the embedded connector 40 and improve its seismic performance. Furthermore, the embedded connector 40 has a simple structure, is easy to install and maintain, and thus reduces construction costs and time. In addition, when the embedded connector 40 is embedded into the concrete base 10 in this embodiment, it increases the foundation area between the embedded connector 40 and the concrete base 10, thereby improving the connection strength between the embedded connector 40 and the concrete base 10. Moreover, the gaps between the first plate 41 and the second plate 42, and between the two first connecting plates 1, can be filled with concrete, further enhancing the stability of the embedded connector 40 within the concrete base 10.

[0078] As a second embodiment of the pre-embedded connector 40 provided in this application, the pre-embedded connector 40 can also be... Figure 10 Specifically, the embedded connector 40, as shown in the diagram, may include a fifth plate 45, a sixth plate 46, and a column 47. The fifth plate 45 and the sixth plate 46 are arranged parallel and spaced apart. The column 47 connects the fifth plate 45 and the sixth plate 46. The column 47 can be constructed as a solid or hollow structure depending on the actual situation. The parallel and spaced arrangement of the fifth plate 45 and the sixth plate 46 provides a stable supporting foundation for the embedded connector 40. The column 47, connecting the fifth plate 45 and the sixth plate 46, plays a role in strengthening and supporting, effectively improving the load-bearing capacity of the embedded connector 40. Furthermore, the simple structure facilitates installation and maintenance, thereby reducing construction costs and time.

[0079] Furthermore, in some embodiments of this application, as a first embodiment of the photovoltaic support device 100 provided in the embodiments of this application, such as... Figure 1 and Figure 2 As shown, the concrete base 10 can be constructed as a quadrangular prism structure, the end face of the pre-embedded connector 40 away from the fixed pile 20 can be constructed as a rectangle, the pre-embedded connector 40 can be located at the center of the concrete base 10, the fixing plate 33 and the mounting plate 21 can both be constructed as circles, the concrete base 10 can be provided with two fixing plates 33, the two fixing plates 33 are symmetrically arranged along the pre-embedded connector 40, and two mounting plates 21 are correspondingly arranged and connected to the two fixing plates 33 one by one. The concrete base 10 and the fixed pile 20 are connected by the connecting rod 31. The end of the fixed pile 20 away from the concrete base 10 is constructed as a cone, and the outer surface of the fixed pile 20 can be formed with spiral blades to facilitate the embedding of the fixed pile 20 into the foundation.

[0080] As a second embodiment of the photovoltaic support device 100 provided in this application, such as Figure 3 and Figure 4 As shown, the concrete base 10 can be constructed as a triangular prism (a triangular prism with three corners removed). The end face of the embedded connector 40 away from the fixed pile 20 can be circular. The embedded connector 40 can be located at the center of the concrete base 10. Three fixing plates 33 can be provided on the concrete base 10. Both the fixing plates 33 and the mounting plates 21 can be circular. The three fixing plates 33 are evenly distributed along the circumference of the embedded connector 40, and the three mounting plates 21 are arranged one-to-one with the three fixing plates 33. The concrete base 10 and the fixed pile 20 are connected by a connecting rod 31. The end of the fixed pile 20 away from the concrete base 10 is constructed as a cone, and the outer surface of the fixed pile 20 can be formed with spiral blades to facilitate the embedding of the fixed pile 20 into the foundation. Thus, on-site concrete pouring can be avoided or reduced, and the concrete base 10 and the fixed pile 20 can be directly assembled and used on-site. The construction process is easy to control, reducing the construction difficulty and time cost of the photovoltaic support device 100.
