Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel frame technology, and in particular to an anti-bending aluminum profile frame for solar photovoltaic panels. Background Technology

[0002] Most solar photovoltaic panels are installed outdoors, enduring long-term exposure to complex and changing environmental factors. Under wind, the panel frames must withstand significant wind pressure, making them prone to bending and deformation. In winter, heavy snowfall exerts immense pressure on the frames, which can also cause them to bend and break. Furthermore, the thermal expansion and contraction caused by diurnal temperature variations can gradually lead to fatigue and deformation of the frames over long-term use.

[0003] However, existing aluminum frame profiles for photovoltaic panels have significant deficiencies in terms of bending resistance. Some frames use a single material and a simple structural design, which cannot effectively disperse and buffer external forces. They are unable to withstand various external forces in complex environments, frequently experiencing bending deformation. This, in turn, affects the internal circuit connections of the photovoltaic panel, reduces power generation efficiency, and may even cause the photovoltaic panel to crack and be damaged. Utility Model Content

[0004] The purpose of this invention is to provide a bending-resistant aluminum profile frame for solar photovoltaic panels, which solves the problems of poor bending resistance, low structural strength, and inability to withstand long-term use of photovoltaic panel frames.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bending-resistant aluminum profile frame for solar photovoltaic panels includes a frame body, which comprises a protective layer, a buffer layer, and a reinforcing layer from the inside out. The inner and outer sides of the buffer layer are bonded to the protective layer and the reinforcing layer respectively by strong adhesive. The outer wall of the reinforcing layer is uniformly provided with long grooves along its length. The inner wall of the protective layer is provided with a boss for supporting the photovoltaic panel, and the surface of the boss is provided with corresponding bolt positioning holes.

[0007] Preferably, the protective layer is made of aluminum profile.

[0008] Preferably, the reinforcing layer is made of high-strength aluminum alloy.

[0009] Preferably, the inner wall of the reinforcing layer and the outer wall of the protective layer are uniformly provided with protrusions, and the inner wall and outer wall of the buffer layer are respectively provided with grooves; the shapes of the protrusions and the grooves are adapted to each other.

[0010] Preferably, the length direction of the long groove is consistent with the length direction of the frame body.

[0011] Preferably, the buffer layer is composed of a rubber-coated shape memory alloy mesh, and the alloy mesh has a hexagonal structure.

[0012] This utility model has at least the following beneficial effects:

[0013] The reinforcing layer is made of high-strength aluminum alloy and features long grooves, which effectively enhances stress distribution and improves the overall bending resistance of the frame. This allows it to better withstand external forces such as wind and snow pressure, ensuring the structural stability of the photovoltaic panel in complex environments.

[0014] The buffer layer is composed of a hexagonal shape memory alloy mesh wrapped in rubber. The combination of the elasticity of rubber and the properties of the shape memory alloy mesh enables the buffer layer to effectively absorb and buffer external impact forces, reduce the impact of external forces on the photovoltaic panel, protect the photovoltaic panel from damage, and effectively cope with the thermal expansion and contraction of the protective layer and the reinforcing layer.

[0015] The protective layer, buffer layer, and reinforcing layer are joined by protrusions and grooves, which increases the bonding area and improves the stability of the connection between the layers. At the same time, the design of the inner wall protrusions and bolt positioning holes of the protective layer ensures a firm connection between the photovoltaic panel and the frame, preventing loosening during long-term use.

[0024] Reference Figure 1-4 A bending-resistant aluminum profile frame for solar photovoltaic panels includes a frame body 1 comprising, from the inside out, a protective layer 11, a buffer layer 12, and a reinforcing layer 13. The inner and outer sides of the buffer layer 12 are bonded to the protective layer 11 and the reinforcing layer 13 respectively with strong adhesive. The outer wall of the reinforcing layer 13 is uniformly provided with long grooves 131 along its length. The inner wall of the protective layer 11 is provided with a boss 14 for supporting the photovoltaic panel. The surface of the boss 14 is provided with corresponding bolt positioning holes 141. The photovoltaic panel is placed on the surface of the boss 14 and then fixed to the surface with bolts.

[0025] Furthermore, the protective layer 11 is made of aluminum profile and is used to directly contact the photovoltaic panel to provide protection for the photovoltaic panel.

[0026] Furthermore, the reinforcing layer 13 is made of high-strength aluminum alloy to enhance the overall bending resistance of the frame.

[0027] Furthermore, the inner wall of the reinforcing layer 13 and the outer wall of the protective layer 11 are uniformly provided with protrusions 132, and the inner wall and outer wall of the buffer layer 12 are respectively provided with grooves; the protrusions 132 and the grooves are adapted to each other, and the cooperation between the protrusions 132 and the grooves increases the bonding area of ​​the protective layer 11, the buffer layer 12 and the reinforcing layer 13, thereby improving the stability of the frame body 1 structure.

[0028] Furthermore, the length direction of the long groove 131 is consistent with the length direction of the frame body 1. The long groove 131 is used to enhance the stress distribution of the reinforcing layer 13 and improve the bending resistance of the frame body 1.

[0029] Furthermore, the buffer layer 12 is composed of a shape memory alloy mesh 121 wrapped in a rubber sleeve 122. The shape memory alloy mesh 121 has a hexagonal structure. The rubber sleeve 122 has good elasticity and flexibility, which can effectively absorb and buffer external impact forces. When the photovoltaic panel is subjected to collision, compression, or vibration caused by environmental factors, the rubber sleeve 122 can act as a buffer pad, reducing the direct impact of external forces on the photovoltaic panel and protecting it from damage. The shape memory alloy mesh 121 has a hexagonal structure. Hexagons have unique geometric stability. When subjected to external compression or tensile deformation, the hexagonal structure can evenly distribute stress, avoiding stress concentration at a certain point that could lead to material damage. At the same time, the hexagonal structures are interconnected to form a mesh, providing a certain degree of support strength for the entire buffer layer 12. In addition, the shape memory alloy has a shape memory effect. When the external force disappears, the shape memory alloy mesh 121 can quickly return to its original shape, ensuring that the buffer layer 12 continues to have good buffering performance. This ensures that the photovoltaic panel aluminum profile frame maintains effective protection for the photovoltaic panel during long-term use, improving the service life and reliability of the photovoltaic panel.

[0030] In summary, the reinforcing layer 13 is made of high-strength aluminum alloy and has long grooves 131, which effectively enhances stress distribution, improves the overall bending resistance of the frame, and can better resist external forces such as wind and snow pressure, ensuring the structural stability of the photovoltaic panel in complex environments.

[0031] The buffer layer 12 is composed of a hexagonal shape memory alloy mesh 121 wrapped in rubber. The combination of the elasticity of the rubber and the properties of the shape memory alloy mesh 121 enables the buffer layer 12 to effectively absorb and buffer external impact forces, reduce the impact of external forces on the photovoltaic panel, protect the photovoltaic panel from damage, and effectively cope with the thermal expansion and contraction of the protective layer 11 and the reinforcing layer 13.

[0032] The protective layer 11, buffer layer 12 and reinforcing layer 13 are connected by the cooperation of the protrusions 132 and the grooves, which increases the bonding area and improves the stability of the connection between the layers. At the same time, the design of the inner wall protrusions 14 and bolt positioning holes 141 of the protective layer 11 ensures a firm connection between the photovoltaic panel and the frame and prevents loosening during long-term use.
