[0006] Beneficial effects: By using a ballast structure to fix some of the supporting components under ballast, the mutual force transmission between the ballast structure and the supporting components is ensured, which improves the load-bearing capacity and pull-out resistance of the double-slope photovoltaic support; by using supporting components, it is easy to assemble and disassemble the pressed components and supporting components, which simplifies the construction and installation process and improves installation efficiency compared with the combination of columns, fixing seats and clamps in related technologies; the supporting components are integrally molded, reducing construction errors.

[0007] In one optional embodiment, the first pressing assembly includes a base, a first pressing member, and a first fastener. The base is connected to the bottom beam, and the first fastener passes through the first pressing member and is fastened to the base. A first clamping groove is formed between the first pressing member and the base.

[0008] Beneficial effects: The first clamping part forms a first clamping groove between itself and the base. The first clamping groove can reliably clamp and fix the edge of the photovoltaic module, preventing the photovoltaic module from loosening or shifting under external forces such as wind load. At the same time, the through-type fastening structure design of the fastener not only ensures the firmness of the pressing and fixing, but also facilitates the disassembly and maintenance of the photovoltaic module in the later stage.

[0009] In one optional embodiment, the first pressing member includes a first pressing part, a second supporting part, and a third connecting part. The two ends of the third connecting part are respectively connected to the first pressing part and the second supporting part.

The first fastener passes through the third connecting part and is fastened to the base.

[0010] In one alternative embodiment, the base has an elongated groove, and the first fastener passes through the first pressing member and the elongated groove in sequence, and is fastened to the base.

[0011] Beneficial effects: By creating long grooves on the base, the adjustable range for installing photovoltaic modules is increased, avoiding the inability to install due to uneven ground, component manufacturing errors, or installation errors.

[0012] In one optional embodiment, the second pressing assembly includes a second pressing member and a second fastener, the second fastener passing through the second pressing member and fastened to the first connecting portion, and a second clamping groove forming between the second pressing member and the first connecting portion.

The second fastener passes through the fourth connecting part and is fastened to the first connecting part.

[0015] In one alternative embodiment, the ballast structure has an embedding groove, and the bottom beam and part of the second connecting portion are embedded in the embedding groove.

[0016] Beneficial effects: By creating an embedding groove in the ballast structure and embedding the bottom beam and part of the second connection into the embedding groove, the overall load-bearing capacity of the double-slope photovoltaic support is further improved.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0028] According to an embodiment of the present invention, in a first aspect, a dual-slope photovoltaic support structure is provided, comprising a base beam 10, a support member 20, a first pressing assembly 30, a second pressing assembly 40, and a ballast structure 50; the support member 20 has a symmetrical structure and includes a first connecting portion 21, a second connecting portion 22, and a first supporting portion 23. Two copies of each of the first connecting portions 21, second connecting portions 22, and first supporting portions 23 are provided. The ends of the two first connecting portions 21 that are close to each other are connected, and the ends of the two first connecting portions 21 that are far apart from each other are respectively connected to the two first supporting portions 23. The ends of the two first supporting portions 23 that are far apart from the first connecting portions 21 are respectively connected to the two second connecting portions 22. Both second connecting parts 22 are connected to the bottom beam 10. The first connecting part 21, the second connecting part 22 and the first support part 23 are integrally formed. There are two first pressing components 30, which are respectively located near the two ends of the bottom beam 10. There are two second pressing components 40, which are respectively connected to the two first connecting parts 21. The space between the first pressing components 30 and the second pressing components 40 is suitable for placing the photovoltaic module 70. There are two ballast structures 50, which are respectively located on both sides of the support 20. The ballast structures 50 press on the bottom beam 10 and press on part of the second connecting parts 22.

[0029] The dual-slope photovoltaic support system of this embodiment uses a ballast structure 50 to fix part of the support member 20 under ballast, ensuring the mutual force transmission between the ballast structure 50 and the support member 20, thereby improving the load-bearing capacity and pull-out resistance of the dual-slope photovoltaic support system. By using the support member 20, it is easy to assemble and disassemble the pressing component and the support member 20. Compared with the combination of column and fixing seat and clamp in related technologies, it simplifies the construction and installation process and improves the installation efficiency. The support member 20 is integrally formed, reducing construction errors.

[0030] It should be noted that in related technologies, when photovoltaic support columns are exposed to wind conditions, they are prone to shifting after being subjected to upward or horizontal forces. This weakens the overall load-bearing and pull-out resistance of the photovoltaic support, thus affecting its overall stability.

[0031] Therefore, in this embodiment, by setting up a ballast structure 50 and cooperating with the support member 20, when there is a vertical wind suction condition, the ballast structure 50 prevents the support member 20 from moving upward, thereby effectively providing pull-out resistance for the overall structure. When there is a horizontal wind load condition, it prevents the support member 20 from moving horizontally, thereby effectively providing pull-out resistance for the overall structure.

[0032] Specifically, such as Figure 4 As shown, the support member 20 has mounting holes to facilitate connection and installation with the first pressing assembly 30 and the bottom beam 10.

[0033] Specifically, such as Figure 4 As shown, a reinforcing beam is provided on the first support portion 23 of the support member 20 to improve the overall structural strength of the first support portion 23.

[0034] Specifically, in this embodiment, the ballast structure 50 is a concrete ballast.

[0035] Of course, in other alternative embodiments, the ballast structure 50 may also be made of other materials.

[0036] In one embodiment, such as Figure 2 As shown, the first pressing assembly 30 includes a base 31, a first pressing member 32 and a first fastener 33. The base 31 is connected to the bottom beam 10. The first fastener 33 passes through the first pressing member 32 and is fastened to the base 31. A first clamping groove is formed between the first pressing member 32 and the base 31.

[0037] Furthermore, such as Figure 2 As shown, the first pressing part 32 includes a first pressing part 321, a second supporting part 322 and a third connecting part 323. The two ends of the third connecting part 323 are respectively connected to the first pressing part 321 and the second supporting part 322. A first clamping groove is formed between the first pressing part 321 and the base 31. Part of the third connecting part 323 is adapted to abut against the photovoltaic module 70. The first fastener 33 passes through the third connecting part 323 and is fastened to the base 31.

[0038] It is worth noting that a first clamping groove is formed between the first pressing component 32 and the base 31. The first clamping groove can reliably clamp and fix the edge of the photovoltaic module 70, preventing the photovoltaic module 70 from loosening or shifting under external forces such as wind load. At the same time, the through-type fastening structure design of the fastener not only ensures the firmness of the pressing and fixing, but also facilitates the disassembly and maintenance of the photovoltaic module 70 in the later stage.

[0039] In one embodiment, such as Figure 2 As shown, a long groove 311 is provided on the base 31, and the first fastener 33 passes through the first pressing part 32 and the long groove 311 in sequence and is fastened to the base 31.

[0040] It is worth noting that by opening a long groove 311 on the base 31, the adjustable range of the photovoltaic module 70 is increased, avoiding the inability to install due to uneven ground, component production errors, or installation errors.

[0041] Furthermore, such as Figure 2 As shown, the base 31 and the bottom beam 10 are connected by double through bolts, which provides a better fixing effect than the plastic wing nuts commonly used in related technologies, and increases the reliability of the connection between the base 31 and the bottom beam 10.

[0042] In one embodiment, such as Figure 3 As shown, the second pressing assembly 40 includes a second pressing member 41 and a second fastener 42. The second fastener 42 passes through the second pressing member 41 and is fastened to the first connecting portion 21. A second clamping groove is formed between the second pressing member 41 and the first connecting portion 21.

[0043] Furthermore, such as Figure 3 As shown, the second pressing part 41 includes a second pressing part 411, a third supporting part 412 and a fourth connecting part 413. The two ends of the fourth connecting part 413 are respectively connected to the second pressing part 411 and the third supporting part 412. A second clamping groove is formed between the second pressing part 411 and the first connecting part 21. Part of the fourth connecting part 413 is adapted to abut against the photovoltaic module 70. The second fastener 42 passes through the fourth connecting part 413 and is fastened to the first connecting part 21.

[0044] It is worth noting that a second clamping groove is formed between the second pressing part 41 and the first connecting part 21. The second clamping groove can reliably clamp and fix the edge of the photovoltaic module 70, preventing the photovoltaic module 70 from loosening or shifting under external forces such as wind load. At the same time, the through-type fastening structure design of the fastener not only ensures the firmness of the pressing and fixing, but also facilitates the disassembly and maintenance of the photovoltaic module 70 in the later stage.

[0045] In one embodiment, such as Figure 5 As shown, the ballast structure 50 has an embedding groove 51, and the bottom beam 10 and part of the second connecting part 22 are embedded in the embedding groove 51.

[0046] It should be noted that if the ballast structure 50 directly ballasts the bottom beam 10 and the second connecting part 22, due to the small contact area, the ballast structure 50 is prone to relative displacement with the bottom beam 10 and the second connecting part 22 during vibration.

[0047] It is worth noting that by opening an embedding groove 51 on the ballast structure 50, the bottom beam 10 and part of the second connecting part 22 are embedded into the embedding groove 51, which increases the contact area between the ballast structure 50 and the bottom beam 10 and the second connecting part 22, and further improves the overall load-bearing capacity of the double-slope photovoltaic support.

[0048] In one embodiment, such as Figure 4 As shown, the second connecting part 22 includes a raised structure 221 and a fixed structure 222. The raised structure 221 is connected to the fixed structure 222, and the fixed structure 222 is connected to the first support part 23. The end of the raised structure 221 away from the fixed structure 222 is spaced apart from the bottom beam 10, and the end of the raised structure 221 away from the fixed structure 222 abuts against the ballast structure 50.

[0049] Specifically, in combination Figure 1 and Figure 4As shown, the fixed structure 222 abuts against the bottom beam 10 and is connected by bolts. The end of the raised structure 221 away from the fixed structure 222 is spaced apart from the bottom beam 10, that is, the raised structure 221 is raised in the direction away from the bottom beam 10.

[0050] It is worth noting that the end of the raised structure 221 away from the fixed structure 222 is raised away from the bottom beam 10 and abuts against the ballast structure 50, which can prevent relative displacement between the support member 20 and the ballast structure 50, thereby resisting the action of external wind load and improving the overall structural stability.

[0051] According to an embodiment of the present invention, in a second aspect, a photovoltaic system is also provided, including the above-mentioned double-slope photovoltaic support and photovoltaic modules 70. Two photovoltaic modules 70 are provided, and the two photovoltaic modules 70 are sandwiched between the first pressing component 30 and the second pressing component 40 to form a triangular structure.

[0052] The photovoltaic system implemented in this embodiment forms a symmetrical and stable triangular structure through the double-slope photovoltaic support and photovoltaic modules 70, thereby improving the overall stability of the photovoltaic system.

[0053] In one embodiment, such as Figure 6 As shown, the double-slope photovoltaic support system has at least two intervals.

[0054] Specifically, such as Figure 6 As shown in this embodiment, there are two photovoltaic support brackets spaced apart.

[0055] Of course, in other alternative implementations, the number of dual-slope photovoltaic supports can be adjusted according to actual needs.

[0056] It is worth noting that by setting up multiple double-slope photovoltaic supports, the overall structural stability of the photovoltaic system is further improved.

[0057] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended invention.
