Description

Technical Field

[0001] This application relates to the field of solar power generation technology, specifically to a photovoltaic frame. Background Technology

[0002] In solar photovoltaic (PV) power generation systems, the PV frame, as a crucial component of PV modules, plays a vital role in supporting and protecting the PV panels and facilitating installation. With the rapid development of the PV industry, increasingly higher demands are being placed on the performance and production efficiency of PV frames.

[0003] Traditional photovoltaic (PV) frames are typically constructed using a single material. This structure makes the frames insufficiently strong when facing complex operating environments, such as strong winds and blizzards, leading to deformation and breakage, which in turn affects the overall stability and lifespan of the PV modules.

[0004] In the production of some frames using composite materials, different molding processes for each material are required. During pultrusion, the process needs to be interrupted multiple times to add material. This process can easily lead to loose bonding between materials, affecting the overall performance of the frame. Traditional processes struggle to achieve efficient and low-cost production while maintaining frame strength. Utility Model Content

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and feature vectors in the embodiments of this application can be arbitrarily combined with each other.

[0039] Traditional photovoltaic (PV) frames are typically constructed using a single material. This structure makes the frames insufficiently strong when facing complex operating environments, such as strong winds and blizzards, leading to deformation and breakage, which in turn affects the overall stability and lifespan of the PV modules.

[0040] In the production of some frames using composite materials, different molding processes for each material are required. During pultrusion, the process needs to be interrupted multiple times to add material. This process can easily lead to loose bonding between materials, affecting the overall performance of the frame. Traditional processes struggle to achieve efficient and low-cost production while maintaining frame strength.

[0041] To address the aforementioned problems, this application provides a photovoltaic frame, comprising a substrate and a webbing. The substrate includes a top plate, a mounting plate, a bottom plate, a first support plate, a second support plate, and a third support plate. The bottom plate, the first support plate, the mounting plate, and the second support plate are sequentially connected to form a corner bracket mounting portion. The top plate and the third support plate are connected to form a photovoltaic panel mounting portion. The second support plate and the third support plate are connected to connect the photovoltaic panel mounting portion and the corner bracket mounting portion. At least one webbing is disposed within the substrate. In this design, at least one webbing extends continuously along the top plate, the third support plate, the second support plate, the bottom plate, the first support plate, and the mounting plate in a cross section perpendicular to the length direction of the substrate; or at least one webbing extends continuously along the top plate, the third support plate, the mounting plate, the first support plate, the bottom plate, and the second support plate in a cross section perpendicular to the length direction of the substrate. This improves the structural strength of the photovoltaic frame in different directions, prevents the photovoltaic frame from deforming under stress, and avoids the problem of repeatedly interrupting the pultrusion process to add fabric. This allows the pultrusion process to be completed by adding webbing only once, reducing the production cost of the photovoltaic frame and improving production efficiency.

[0042] An exemplary embodiment of this application provides a photovoltaic frame, see [link]. Figures 1-2 as well as Figures 7-8 The photovoltaic frame includes a substrate 1 and at least one webbing.

[0043] The substrate 1 includes a top plate 11, a mounting plate 12, a bottom plate 13, a first support plate 14, a second support plate 15, and a third support plate 16. The bottom plate 13, the first support plate 14, the mounting plate 12, and the second support plate 15 are sequentially connected to form a corner bracket mounting part 18. The corner bracket mounting part 18 has a frame structure and is used to install corner brackets. For example, the photovoltaic frame can have four substrates 1 connected by corner brackets. The corner brackets are inserted into the corner bracket mounting parts 18 of the substrates 1 to connect adjacent substrates 1 in pairs to form an enclosing structure. The four substrates 1, through the cooperation of the corner bracket mounting parts 18 and the corner brackets, achieve a reliable connection between adjacent substrates 1, forming a stable enclosing structure, ensuring the accuracy and firmness of the photovoltaic frame splicing, and improving the overall stability of the photovoltaic module.

[0044] The top plate 11 and the third support plate 16 are connected to form a photovoltaic panel mounting part 17. The photovoltaic panel mounting part 17 is L-shaped, and the photovoltaic panel is installed in the photovoltaic panel mounting part 17. The second support plate 15 is disposed away from the bottom plate 13 relative to the third support plate 16, and the second support plate 15 is connected to the junction of the third support plate 16 and the mounting plate 12. In a cross-section perpendicular to the extension direction of the substrate 1, the second support plate 15 is connected to the third support plate 16, and the extension directions of the second support plate 15 and the third support plate 16 are the same. The second support plate 15 is connected to the third support plate 16 to connect the photovoltaic panel mounting part 17 and the corner bracket mounting part 18.

[0045] In some embodiments, see Figure 7 At least one webbing 2 is disposed within the base 1, wherein, on a cross section perpendicular to the length direction of the base 1, at least one webbing 2 extends sequentially along the top plate 11, the third support plate 16, the second support plate 15, the bottom plate 13, the first support plate 14 and the mounting plate 12.

[0046] In some embodiments, see Figure 8 On a cross section perpendicular to the length direction of the base 1, at least one webbing 2 extends sequentially along the top plate 11, the third support plate 16, the mounting plate 12, the first support plate 14, the bottom plate 13, and the second support plate 15.

[0047] In this application, at least one continuously extending webbing 2 is provided within the substrate 1, such that webbing 2 is correspondingly provided within any one of the following plates: top plate 11, mounting plate 12, bottom plate 13, first support plate 14, second support plate 15, and third support plate 16. This enhances the overall structural strength of the photovoltaic frame. When subjected to external forces, the webbing 2 can evenly distribute stress, effectively preventing deformation or damage caused by excessive local stress, allowing the photovoltaic frame to stably support the photovoltaic panel even in harsh environments. For example, in extreme weather conditions such as strong winds and blizzards, it can ensure the integrity of the photovoltaic module and reduce the risk of failure. In this embodiment, the webbing 2 extends continuously within multiple plates of the substrate 1. This design allows the entire photovoltaic frame to be embedded inside the substrate 1 and pultruded by adding webbing only once during the pulling process, significantly simplifying the processing technology, reducing production costs, and improving production efficiency.

[0048] An exemplary embodiment of this application provides a photovoltaic frame, referring to... Figures 1-6 The photovoltaic frame includes a substrate 1 and at least two webbing strips 2.

[0049] The substrate 1 includes a top plate 11, a mounting plate 12, a bottom plate 13, a first support plate 14, a second support plate 15, and a third support plate 16. The bottom plate 13, the first support plate 14, the mounting plate 12, and the second support plate 15 are sequentially connected to form a corner bracket mounting part 18. The corner bracket mounting part 18 has a frame structure and is used to install corner brackets. For example, the photovoltaic frame can have four substrates 1 connected by corner brackets. The corner brackets are inserted into the corner bracket mounting parts 18 of the substrates 1 to connect adjacent substrates 1 in pairs to form an enclosing structure. The four substrates 1, through the cooperation of the corner bracket mounting parts 18 and the corner brackets, achieve a reliable connection between adjacent substrates 1, forming a stable enclosing structure, ensuring the accuracy and firmness of the photovoltaic frame splicing, and improving the overall stability of the photovoltaic module.

[0050] The top plate 11 and the third support plate 16 are connected to form a photovoltaic panel mounting part 17. The photovoltaic panel mounting part 17 is L-shaped, and the photovoltaic panel is installed in the photovoltaic panel mounting part 17. The second support plate 15 is disposed away from the bottom plate 13 relative to the third support plate 16, and the second support plate 15 is connected to the junction of the third support plate 16 and the mounting plate 12. In a cross-section perpendicular to the extension direction of the substrate 1, the second support plate 15 is connected to the third support plate 16, and the extension directions of the second support plate 15 and the third support plate 16 are the same. The second support plate 15 is connected to the third support plate 16 to connect the photovoltaic panel mounting part 17 and the corner bracket mounting part 18.

[0051] In some embodiments, refer to Figure 3 At least two webbing strips 2 are disposed within the base 1, wherein, on a cross section perpendicular to the length direction of the base 1, at least one webbing strip 2 extends continuously along the top plate 11, the third support plate 16, the second support plate 15 and the bottom plate 13 in sequence, and at least another webbing strip 2 extends continuously along the mounting plate 12 and the first support plate 14 in sequence. Figure 1 The first direction is defined as the length direction of the base 1.

[0052] In some embodiments, refer to Figure 4 On a cross section perpendicular to the length direction of the base 1, at least one webbing 2 extends continuously along the top plate 11, the third support plate 16, the mounting plate 12 and the first support plate 14 in sequence, and at least another webbing 2 extends continuously along the second support plate 15 and the bottom plate 13 in sequence.

[0053] In this application, at least two continuously extending webbing strips 2 are provided within the substrate 1, such that webbing strips 2 are correspondingly provided within any one of the following plates: top plate 11, mounting plate 12, bottom plate 13, first support plate 14, second support plate 15, and third support plate 16. On the one hand, when the photovoltaic frame is subjected to external force, the multiple webbing strips 2 can disperse the stress from different directions, which not only avoids excessive local stress but also effectively suppresses the photovoltaic frame from twisting, bending, and other deformations under complex external forces, further improving the stability of the photovoltaic frame in supporting the photovoltaic panel under harsh environments and reducing the risk of photovoltaic system failure due to damage to the photovoltaic frame. On the other hand, the multiple continuously extending webbing strips 2 can also be embedded and formed in a single pultrusion process, eliminating the need for multiple additional pultrusion operations, simplifying the process, and improving the forming quality and production efficiency of the photovoltaic frame.

[0054] In some embodiments, see Figures 1-6 At least two webbing straps 2 are provided inside at least one of the first support plate 14, the mounting plate 12, and the second support plate 15. The photovoltaic panel is installed within the photovoltaic panel mounting section 17 and rests on the mounting plate 12. The photovoltaic panel is subjected to gravity, which exerts pressure on the mounting plate 12, the first support plate 14, and the second support plate 15. Therefore, the mounting plate 12, the first support plate 14, and the second support plate 15 need to provide more support for the photovoltaic panel. By providing at least two webbing straps 2 inside at least one of the first support plate 14, the mounting plate 12, and the second support plate 15, the load-bearing capacity of the first support plate 14, the mounting plate 12, and the second support plate 15 is enhanced. When the gravity of the photovoltaic panel acts on the mounting plate 12 and is then transferred to the first support plate 14 and the second support plate 15, the webbing straps, due to their high strength, can effectively distribute the pressure, dispersing the concentrated gravity across the entire substrate 1 structure. This improves the support strength of these three key components for the photovoltaic panel and prevents deformation and breakage due to long-term heavy pressure. Due to the reinforcing effect of the webbing, under the premise of meeting the same support requirements, the selection of the base material can be appropriately optimized or the amount of material used can be reduced, so as to effectively control the production cost while ensuring product quality.

[0055] In some embodiments, refer to Figure 1 The extension direction of the webbing 2 is consistent with the length direction of the substrate 1, which makes the laying of the webbing 2 inside the substrate 1 smoother and effectively improves production efficiency. When external force is applied to the photovoltaic frame, since the webbing 2 is consistent with the length direction of the substrate 1, it can more efficiently transfer and disperse stress in the length direction of the substrate 1, avoid local stress concentration, and enhance the support strength of the photovoltaic frame.

[0056] In some embodiments, refer to Figure 6The webbing 2 is woven from multiple threads to form a woven structure. When external force is applied to the photovoltaic frame, it can disperse stress in the extension direction of the multiple threads, thereby enhancing the structural strength and support strength of the photovoltaic frame.

[0057] In some embodiments, refer to Figure 6 The multiple weave lines include multiple first weave lines 21 and multiple second weave lines 22. The multiple first weave lines 21 are arranged side by side, and the extension direction of the multiple first weave lines 21 is consistent with the length direction of the substrate 1. The multiple second weave lines 22 are arranged side by side along the extension direction of the first weave lines 21, so that when an external force is applied to the photovoltaic frame, the external force is transmitted along the length direction of the substrate 1 through the first weave lines 21, and the external force is dispersed and transmitted along the extension direction of the multiple second weave lines 22, so that the stress is distributed throughout the photovoltaic frame and stress concentration is avoided.

[0058] In some embodiments, refer to Figure 6 Within the same webbing 2, multiple first webbing threads 21 are arranged side by side, and the multiple first webbing threads 21 include at least a first parallel webbing thread 211, a second parallel webbing thread 212 and a third parallel webbing thread 213 arranged in sequence adjacent to each other.

[0059] The second thread 22 passes from the upper side of the first parallel thread 211 to the lower side of the second parallel thread 212, and from the lower side of the second parallel thread 212 to the upper side of the third parallel thread 213. Multiple first threads 21 and multiple second threads 22 are woven together in this manner to form the webbing 2. The multiple first threads 21 and second threads 22 interweave to form a tight and stable mesh structure. The first parallel threads 211, second parallel threads 212, and third parallel threads 213 in the first thread 21 have enhanced synergy due to the interlacing connection of the second threads 22. When the webbing is subjected to external force, the force is evenly distributed to each first thread 21 through the second threads 22, preventing a single thread from breaking due to excessive tension. This results in higher overall tensile strength for the webbing, enabling it to better cope with the stresses experienced by the photovoltaic frame under various operating conditions.

[0060] In some embodiments, the plane containing the second thread 22 is perpendicular to the first thread 21, so that the first thread 21 and the second thread 22 can be woven together to form the webbing 2.

[0061] In some embodiments, a gap is provided between adjacent first threads 21, which helps to reduce the weight of the webbing while ensuring the structural strength of the webbing.

[0062] In some embodiments, a gap is provided between adjacent second webbing threads 22, which helps to reduce the weight of the webbing while ensuring the structural strength of the webbing.

[0063] The spacing between the webbing 2 and the substrate 1 allows the substrate 1 material to be better filled during processes such as pultrusion molding, which enhances the bonding force between the webbing 2 and the substrate 1. This makes the webbing 2 and the substrate 1 a more compact whole, working together to cope with complex external forces and further strengthening the structural stability of the photovoltaic frame.

[0064] In some embodiments, adjacent first threads 21 abut against each other, which can improve the overall rigidity of the webbing 2 and enhance the compressive strength of the photovoltaic frame.

[0065] In some embodiments, adjacent second threads 22 abut against each other, which can improve the overall rigidity of the webbing 2 and enhance the compressive strength of the photovoltaic frame.

[0066] The abutting of adjacent first threads 21 or adjacent second threads 22 makes the internal structure of the webbing 2 more compact, increasing the thread density per unit volume and effectively improving the overall rigidity of the webbing. When facing complex external forces on the photovoltaic frame, this compact structure can more efficiently cooperate in bearing the force, enhancing local pressure resistance. For example, when the photovoltaic panel exerts concentrated pressure on the frame due to snow accumulation, the abutting first threads 21 can quickly disperse the pressure throughout the webbing area due to their tightly arranged structure, preventing local areas from denting or breaking due to excessive pressure.

[0067] In some embodiments, refer to Figure 5 Two webbing strips 2 are disposed within the first support plate 14. A space is provided between the two webbing strips on a cross-section parallel to the base plate 13. This design allows the two webbing strips to provide support to the first support plate 14 from different positions when the photovoltaic frame is subjected to external forces from different directions, such as the horizontal thrust generated by strong winds. The space allows the two webbing strips 2 to independently and collaboratively cope with external forces, preventing excessive stress on one strip from affecting the overall support effect. During the pultrusion process, the matrix material 1 can fill the space between the two webbing strips, making the bond between the two webbing strips and the matrix material 1 tighter and strengthening the overall structural strength of the photovoltaic frame.

[0068] In some embodiments, refer to Figure 4 The photovoltaic frame also includes a protective layer 3, which covers the surface of the substrate 1 and can improve the corrosion resistance and weather resistance of the photovoltaic frame.

[0069] The protective layer 3 can be set as a paint layer or a nylon layer. The paint layer is made of paint, and the nylon layer is made of nylon. Paint and nylon have good waterproof, moisture-proof, UV-proof, and oxidation-proof properties, which can effectively protect the photovoltaic frame from external environmental erosion and extend its service life.
