Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a high-strength photovoltaic support suitable for atmospheric corrosion environments of C4 and above. Background Technology

[0002] As a crucial component of photovoltaic (PV) power generation systems, the stability and durability of PV modules directly impact their operational performance and power generation efficiency. Currently, most PV support systems utilize steel as their primary material. While steel possesses good strength and toughness, its corrosion resistance is poor. The conventional solution is to hot-dip galvanize or zinc-aluminum-magnesium plating on the steel surface to achieve corrosion resistance. However, in C4 and higher atmospheric corrosive environments, such as coastal areas or near chemical plants, this approach often fails to meet corrosion resistance requirements, making a 25-year lifespan impossible. Furthermore, existing technologies require coatings of a certain thickness, which can easily lead to material deformation and alterations in mechanical properties.

[0003] In addition, existing photovoltaic support systems often have relatively fixed structures and can only be used with photovoltaic panels of specific sizes. They do not have the function of adjusting themselves to adapt to photovoltaic panels of different sizes, thus limiting the scope of application of photovoltaic support systems. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a high-strength photovoltaic support suitable for atmospheric corrosion environments of C4 and above. The photovoltaic support is made entirely of weathering steel and includes columns, main beams and several secondary beam components.

[0005] The main beam is rotatably mounted on the top of the column;

[0006] Each secondary beam assembly includes a secondary beam, a connecting piece, and two diagonal braces, with the upper part of the secondary beam used to directly support the photovoltaic panel;

[0007] For any given secondary beam assembly, the secondary beam, the two diagonal braces, and the connecting piece together form a trapezoidal structure.

[0008] The connecting piece and the secondary beam serve as the upper and lower bases of the trapezoidal structure, respectively, and the two diagonal braces serve as the two waists of the trapezoidal structure. The beginning and end of the trapezoidal structure are fixedly connected by bolts.

[0009] In some embodiments, for any secondary beam assembly, there are also two double-ended studs, each stud being configured with two nuts;

[0010] The main beam has a rectangular cross-section, and two double-ended stud fasteners are located on the left and right sides of the main beam, respectively.

[0011] The connecting piece includes a first plane and a second plane that are perpendicular to each other, making its cross-section L-shaped;

[0012] The two ends of the first plane of the connecting piece are respectively fixedly connected to two diagonal braces;

[0013] The second plane of the connecting piece contacts the lower surface of the main beam;

[0014] The secondary beam has an I-shaped cross-section, and its lower surface is in contact with the upper surface of the main beam.

[0015] For any double-ended stud, its two ends pass through the pre-set through holes on the first plane of the connecting piece and the lower surface of the secondary beam, respectively, and the size of the through holes prevents the nuts from passing through. The two ends of the double-ended stud are threadedly connected to two nuts respectively.

[0016] In some embodiments, each stud is further provided with two washers that mate with the nut.

[0017] In some embodiments, the weathering steel material is high weathering steel or weldable weathering steel.

[0019] This utility model provides a high-strength photovoltaic (PV) support system suitable for C4 and above atmospheric corrosion environments. The entire system is made of weather-resistant steel, which exhibits strong corrosion resistance and can operate stably for extended periods in harsh environments, extending service life and improving the reliability of the PV support system. Furthermore, a special structure allows for detachable and fixed connections between the secondary beam components and the main beam, making installation and disassembly convenient and simple. While ensuring structural stability, the position of the secondary beam components can be easily adjusted to accommodate PV modules of different sizes, greatly improving the applicability of the PV support system. In addition, the rotatable main beam allows for adjustment of the overall angle of the PV modules, which, together with the secondary beams and diagonal braces, helps improve the wind resistance performance of the PV support system.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with the accompanying drawings and specific embodiments, further explains how this utility model is implemented.

[0024] Reference Figure 1 and Figure 2 As shown, this utility model provides a high-strength photovoltaic support suitable for atmospheric corrosion environments of C4 and above. The photovoltaic support is made of weathering steel and includes a column 40, a main beam 10, and several secondary beam assemblies. The main beam 10 is rotatably mounted on the top of the column 40. Each secondary beam assembly includes a secondary beam 20, a connecting piece 1, and two diagonal braces 30. The upper part of the secondary beam 20 is used to directly support the photovoltaic panel. For any secondary beam assembly, the secondary beam 20, the two diagonal braces 30, and the connecting piece 1 form a trapezoidal structure. The connecting piece 1 and the secondary beam 20 serve as the upper and lower bases of the trapezoidal structure, respectively, and the two diagonal braces 30 serve as the two waists of the trapezoidal structure. The beginning and end of the trapezoidal structure are fixedly connected by bolts.

[0025] Preferably, for any secondary beam assembly, there are two double-ended studs 2, each double-ended stud 2 being equipped with two nuts 3; the main beam 10 has a rectangular cross-section, and the two double-ended studs 2 fasteners are located on the left and right sides of the main beam 10 respectively; the connecting piece 1 includes a first plane and a second plane that are perpendicular to each other, making its cross-section L-shaped; the two ends of the first plane of the connecting piece 1 are fixedly connected to two diagonal braces 30 respectively; the second plane of the connecting piece 1 is in contact with the lower surface of the main beam 10; the secondary beam 20 has an I-shaped cross-section, and the lower surface of the secondary beam 20 is in contact with the upper surface of the main beam 10; for any double-ended stud 2, its two ends pass through the pre-set through holes on the first plane of the connecting piece 1 and the lower surface of the secondary beam 20 respectively, and the size of the through holes prevents the nuts 3 from passing through, and the two ends of the double-ended stud 2 are threadedly connected to the two nuts 3 respectively.

[0026] Preferably, each double-ended stud 2 is also provided with two washers 4 that mate with the nut 3.

[0027] In addition, the weathering steel materials used are high weathering steel or weldable weathering steel. Specifically, the grades of high weathering steel can be Q295GNH, Q355GNH, Q265GNH or Q310GNH, etc.; the grades of weldable weathering steel can be Q235NH, Q295NH, Q355NH, Q415NH, Q460NH, Q500NH or Q550NH, etc.

[0028] Compared to bolt structures made of traditional hot-dip galvanized materials, bolt structures made of weathering steel do not require a pre-existing gap between the bolt threads for the coating, and the nuts and bolts have a tighter fit, resulting in superior bolt strength and anti-loosening performance.

[0029] In summary, the high-strength photovoltaic support structure provided by this utility model, suitable for atmospheric corrosion environments of C4 and above, is made entirely of weather-resistant steel, which has strong corrosion resistance and can work stably for a long time in harsh environments, extending its service life and improving the reliability of the photovoltaic support system. Furthermore, a special structure allows for detachable fixed connection between the secondary beam components and the main beam, making installation and disassembly convenient and simple. While ensuring structural stability, the position of the secondary beam components can be easily adjusted to accommodate photovoltaic modules of different sizes, greatly improving the applicability of the photovoltaic support system. In addition, the rotatable main beam allows for adjustment of the overall angle of the photovoltaic modules, which, together with the secondary beams and diagonal braces, helps improve the wind resistance performance of the photovoltaic support structure.
