Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a purlin-free roof photovoltaic support system. Background Technology

[0002] In recent years, with the increasing awareness of environmental protection and the intensification of the energy crisis, more and more companies have begun to install photovoltaic modules on the roofs of their factories to achieve green power generation.

[0003] However, when installing photovoltaic modules on the roof of a traditional portal frame structure corrugated steel roof factory building, the original purlins often need to be fully reinforced due to load transfer issues. However, the reinforcement process may affect production and cause unnecessary damage to the original building, which not only increases the difficulty of construction but also significantly increases the project cost. Utility Model Content

[0004] This application provides a purlin-free roof photovoltaic bracket to solve the problem that current purlin-free roof photovoltaic brackets require reinforcement of the original purlins, which affects production and increases costs and construction difficulty.

[0005] A purlin-free roof photovoltaic support system includes:

[0006] Inclined beam;

[0007] The first purlin is provided at the upper end of the inclined beam;

[0008] The roof panel is located at the upper end of the first purlin;

[0009] A support assembly is disposed at the upper end of the roof panel, and the support assembly is correspondingly connected to the inclined beam;

[0010] A photovoltaic module is disposed at the upper end of the support assembly.

[0011] By adopting the above technical solution, the load generated by the photovoltaic module is directly transmitted to the inclined beam through the support structure, thus eliminating the need to reinforce all the purlins, not affecting production and significantly saving costs; at the same time, directly transmitting the load to the inclined beam makes the stress path of the structure clearer and simpler, enhancing the overall structural stability.

[0012] In one embodiment, the support assembly includes a support member and a second purlin, the support member being disposed at the upper end of the roof panel and correspondingly connected to a diagonal beam, and the second purlin being disposed at the upper end of the support member.

[0013] By adopting the above technical solution, the load generated by the photovoltaic modules is first transferred to the support members via the second purlin, and then from the support members to the inclined beams. This layered transfer method makes the load distribution more reasonable, better disperses and bears the load generated by the photovoltaic modules, and ensures the reliability of the structure.

[0014] In one embodiment, the support member is perpendicular to the roof panel, the support member is made of high-strength steel structural material, and the surface of the support member is coated with an anti-corrosion coating.

[0015] By adopting the above technical solution, the support components are perpendicular to the roof panel and made of high-strength steel structural materials, ensuring that the support components can withstand large loads. At the same time, the surface is coated with an anti-corrosion coating, which effectively prevents the support components from losing strength due to rust, thereby ensuring the durability and safety of the entire purlin-free roof photovoltaic support system.

[0016] In one embodiment, the second purlin is made of lightweight, high-strength aluminum alloy, carbon steel, or stainless steel.

[0017] By adopting the above-mentioned technical solutions, these materials possess excellent corrosion resistance, enabling them to be used for extended periods in outdoor environments without easily corroding. Simultaneously, their lightweight and high-strength characteristics allow the second purlin to reduce the overall weight of the support structure while maintaining load-bearing capacity, facilitating installation and transportation, and extending its service life. Furthermore, the fact that the second purlin is made of metal allows it to effectively absorb heat generated by the photovoltaic modules and dissipate heat through the gap between the second purlin and the roof panel.

[0018] In one embodiment, the purlin-free roof photovoltaic support also includes a buffer member located at the lower end of the support member.

[0019] By adopting the above technical solutions, the buffer components can absorb the vibration energy generated during the operation of photovoltaic modules due to factors such as wind and temperature changes, reducing the vibration amplitude and thus minimizing structural fatigue and damage caused by vibration. Simultaneously, reducing noise also helps improve the surrounding environment and extends the service life of the entire purlin-free roof photovoltaic support system.

[0020] In one embodiment, the buffer is a rubber pad or a spring.

[0021] By adopting the above technical solutions, the rubber gasket has a certain degree of flexibility and wear resistance, and can effectively absorb vibration energy; the spring can adjust the elastic coefficient as needed to provide a more precise buffering effect, and the spring can be placed between the support and the inclined beam without affecting the load transmission.

[0022] In one embodiment, multiple first purlins are arranged in a row, and both the inclined beam and the support member are fixed to the end of the first purlins.

[0023] By adopting the above technical solution, this design effectively secures the first purlin, preventing it from loosening. The first purlin plays a supporting and connecting role in the entire structure. Securely fixing the first purlin enhances the overall integrity and stability of the structure, ensuring that the entire purlin-free roof photovoltaic support system can maintain stable operation under various working conditions.

[0024] In one embodiment, the purlin-free roof photovoltaic support also includes a protective element that covers the photovoltaic module.

[0025] By adopting the above technical solutions, in outdoor environments, foreign objects such as leaves, birds, and dust may come into contact with photovoltaic modules. These foreign objects may scratch the surface of the photovoltaic modules, affecting their power generation efficiency or even causing damage. The protective components can effectively prevent this from happening, ensuring the normal operation of the photovoltaic modules and thus ensuring the stable power generation of the entire photovoltaic system.

[0026] In one embodiment, the support member includes an extension that abuts against the surface of the roof panel, and fasteners pass through the extension, the roof panel, and the first purlin to secure the support member.

[0027] By adopting the above technical solution, this connection method allows the load to be transferred not only directly to the inclined beam through the support members, but also partially through the fasteners via the first purlin. This results in a more rational distribution of the load, preventing excessive local loads from damaging the structure and thus protecting it. Simultaneously, the fastener fixation enhances the connection strength between the support members and other components, improving the overall stability of the purlin-free roof photovoltaic support system.

[0028] In one embodiment, the support assembly further includes an adjusting member disposed at the upper end of the support member and hinged to the support member, and the second purlin is disposed at the upper end of the adjusting member.

[0029] By adopting the above technical solution, the adjustment component can adjust the angle between the second purlin and the roof panel, which facilitates better operation of the photovoltaic modules and improves power generation efficiency.

[0030] In summary, this application includes at least one beneficial effect:

[0031] 1. The load generated by the photovoltaic modules is directly transferred to the inclined beams through the support structure, thus eliminating the need to reinforce all the purlins, which does not affect production and significantly saves costs. At the same time, directly transferring the load to the inclined beams makes the stress path of the structure clearer and simpler, enhancing the overall stability of the structure.

[0032] 2. The support components are perpendicular to the roof panel and are constructed from high-strength steel, ensuring they can withstand significant loads. Furthermore, a protective coating or electroplated protective film is applied to the surface, effectively preventing rust. In outdoor environments, rust prevention is crucial for extending the service life of the support components, preventing them from losing strength due to rust, and thus ensuring the durability and safety of the entire purlin-free photovoltaic roof support system.

[0033] 3. This design effectively secures the first purlin, preventing it from loosening. The first purlin plays a supporting and connecting role in the entire structure. Securely fixing the first purlin enhances the overall integrity and stability of the structure, ensuring that the entire purlin-free roof photovoltaic support system can maintain stable operation under various working conditions.

[0038] The following is in conjunction with the appendix Figure 1-3 This application provides a further detailed description of the purlin-free roof photovoltaic support system.

[0039] Example 1

[0040] Please see Figure 1-3 This application provides a purlin-free roof photovoltaic support 1, which includes a diagonal beam 11, a first purlin 12, a roof panel 13, a support assembly 14, and a photovoltaic module 15.

[0041] like Figures 1 to 2As shown, a diagonal beam 11 is installed on the roof, a first purlin 12 is installed at the upper end of the diagonal beam 11, and a roof panel 13 is installed at the upper end of the first purlin 12. Specifically, the first purlin 12 is hollow inside, and multiple purlins can be arranged in an arrangement, with the ends of adjacent first purlins 12 abutting against each other. Similarly, multiple diagonal beams 11 are provided, located at the ends of the first purlins 12 and fixed to two adjacent first purlins 12. The purpose of this design is to better secure the first purlins 12, preventing them from loosening under wind force, thereby ensuring the stability of the entire support structure.

[0042] The support assembly 14 is located at the upper end of the roof panel 13 and corresponds to and connects with the inclined beams 11. The photovoltaic module 15 is located at the upper end of the support assembly 14. Specifically, the support assembly 14 includes a support member 141 and a second purlin 142. The support member 141 is located at the upper end of the roof panel 13 and passes through the roof panel 13 and the first purlin 12, correspondingly connecting with the inclined beams 11. Therefore, the support member 141 is located at the upper end of the end of the first purlin 12. The support member 141 can be made of high-strength steel structural material and coated with an anti-corrosion coating. This not only effectively prevents the support member 141 from rusting due to long-term exposure to the outdoor environment, but also ensures its durability and safety. The support member 141 can be made of common high-strength steel such as Q235B steel plate or Q345C steel plate, or other materials with good anti-corrosion properties, such as stainless steel or galvanized steel. The height of the support member 141 can be adjusted according to the actual situation, and its shape can be "π" shaped or other shapes.

[0043] The purlin-free roof photovoltaic support 1 also includes fasteners 16. Fasteners 16 can pass through the support member 141, the roof panel 13, and be fixed to the inclined beam 11; fasteners 16 can also pass through the support member 141, the roof panel 13, and the first purlin 12 and be fixed to the inclined beam 11. In this embodiment, the support member 141 is π-shaped and includes an extension portion that abuts against the surface of the roof panel 13. Fasteners 16 can pass through the extension portion, the roof panel 13, and the first purlin 12 to fix the support member 141, and also fix the ends of two adjacent first purlins 12, making the overall structure more robust and reliable, preventing loosening. Furthermore, fasteners 16 can transfer part of the load to the inclined beam 11 through the first purlins 12, reducing the load borne by the support member 141 and preventing damage to the support member 141 due to excessive load.

[0044] The second purlin 142 is located at the upper end of the support member 141. Multiple second purlins 142 are provided, and they are arranged parallel to each other and spaced apart. This facilitates the mounting of the photovoltaic module 15 on the second purlins 142. The load generated by the photovoltaic module 15 can be transferred through the second purlins 142 to the support member 141, and then from the support member 141 to the inclined beam 11. The second purlin 142 can be made of lightweight high-strength aluminum alloy, carbon steel, or stainless steel. These materials have good corrosion resistance and a long service life, and can adapt to various harsh environmental conditions. For example, lightweight high-strength aluminum alloy can not only reduce the overall weight but also improve seismic performance; while stainless steel has excellent weather resistance and corrosion resistance, making it suitable for use in coastal areas. Furthermore, the second purlin 142 has a gap between it and the roof panel 13, allowing it to absorb heat generated by the photovoltaic module 15 and dissipate it through this gap.

[0045] The purlin-free photovoltaic roof support 1 also includes a buffer component, which is located at the lower end of the support component 141. Specifically, the buffer component can be a rubber pad or a spring. The rubber pad has good shock absorption effect, effectively absorbing external impacts and vibrations, and also has good sound insulation effect; one end of the spring can be connected to the support component 141, and the other end can be connected to the inclined beam 11. This not only allows it to quickly return to its original shape and maintain the stability of the structure when subjected to a large impact, but also, since the spring is made of metal, the load generated by the photovoltaic module 15 can be easily transferred to the inclined beam 11 through the support component 141.

[0046] like Figure 3 As shown, to prevent damage to the photovoltaic module 15 from foreign objects, the purlin-free roof photovoltaic support 1 also includes a protective element 17, which covers the photovoltaic module 15. The protective element 17 can be made of light-transmitting materials such as transparent polycarbonate sheet or glass fiber reinforced plastic (FRP), which can protect the photovoltaic module 15 from the influence of the external environment without affecting the sunlight, thereby ensuring the normal operation of the photovoltaic module 15.

[0047] The support assembly may also include an adjusting member 143, which is located at the upper end of the support member 141 and hinged to it. A second purlin 142 is located at the upper end of the adjusting member 143. Specifically, the adjusting member 143 can rotate around the upper end of the support member 141, thereby driving the second purlin 142 to adjust its angle. This allows the photovoltaic module 15 to better receive sunlight, thus maintaining a better working condition and improving the efficiency of photovoltaic power generation.

[0048] The implementation principle of this embodiment is as follows: through reasonable design, the load generated by the photovoltaic module 15 is directly transferred to the inclined beam 11, avoiding excessive load on the first purlin 12, thereby greatly reducing the requirements for the first purlin 12 and saving material costs. Simultaneously, through the selection and optimization of the support member 141 and the second purlin 142, the stability and reliability of the entire support structure are improved, and its service life is extended. Furthermore, the addition of buffer and protective components 17 further enhances the safety and durability of the system, making it more suitable for various complex environmental conditions.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
