Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panels, specifically a pressure-resistant aluminum alloy frame structure. Background Technology

[0002] The aluminum alloy frame of a photovoltaic panel is an important supporting structure for solar modules. It is made of high-strength aluminum alloy profiles and features lightweight, corrosion resistance, and wind pressure resistance. The frame is assembled through four-corner splicing or integral molding processes, and the surface is treated with anodizing or powder coating to enhance weather resistance and UV resistance. Its design typically includes water channels, mounting slots, and grounding connection points to facilitate module installation and system integration. The aluminum alloy frame not only protects the solar cells and glass layers but also improves the mechanical strength of the module, ensuring its long-term stable operation outdoors. To ensure optimal light exposure, existing aluminum alloy frames for photovoltaic panels are typically installed at an angle, which exposes their backs directly to airflow, creating a large windward surface. In strong winds, this generates vortices and negative pressure on the back of the frame, increasing the overall wind load. Since aluminum alloy frames are designed for lightweight applications, their structural strength and bending resistance are relatively limited in strong winds, especially with large-sized modules. The frame's support may be insufficient, leading to deformation or loosening of connections, thus affecting the stability and safety of the photovoltaic system.

[0003] In summary, to improve the overall wind resistance of tilted photovoltaic panels, it is necessary to address the issue of aluminum alloy frames being susceptible to structural deformation due to wind pressure under strong wind conditions. This would allow the frames to effectively resist wind load impacts while maintaining their lightweight advantage, thereby ensuring the long-term stable operation of the photovoltaic system under severe weather conditions.

By adding a flow-guiding structure to the back of the photovoltaic frame, the wind resistance of the aluminum alloy frame can be effectively improved, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure-resistant aluminum alloy frame structure, comprising a frame body, two hinge seats installed at the bottom of the frame body, a rotating rod rotatably connected between the two hinge seats, a connecting shell fixed to the outside of the rotating rod, a baffle provided inside the connecting shell, a slider fixed to the outside of the baffle, the baffle slidingly connected to the connecting shell through the slider, two connecting pieces fixed to the end of the baffle, two hooks fixed to the bottom of the frame body, the connecting pieces connected to the hooks through steel wire ropes, a positioning mechanism for positioning photovoltaic panels provided on the frame body, an anti-vibration mechanism for supporting photovoltaic panels provided inside the frame body, and fixing components provided at the four corners of the frame body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention effectively improves the wind resistance of aluminum alloy frames by adding a flow-guiding structure to the back of the photovoltaic frame. This design optimizes airflow direction, reduces back eddies and negative pressure effects, thereby significantly reducing the impact of wind loads on the frame. The flow-guiding structure disperses wind force, avoids local stress concentration, and enhances overall stability without significantly increasing the frame weight or affecting installation convenience. In addition, this design also improves the frame's dynamic wind vibration resistance, reduces the risk of long-term wind-induced fatigue, and extends the service life of photovoltaic modules. In strong wind environments, the flow-guiding structure can maintain the structural integrity of the modules, ensure power generation efficiency, reduce maintenance costs, and provide a guarantee for the reliable operation of photovoltaic systems under complex climatic conditions.

[0016] The present invention will be further described below with reference to specific embodiments.

[0017] Refer to the instruction manual appendix Figures 1 to 5 A pressure-resistant aluminum alloy frame structure includes a frame body 1. Two hinge seats 2 are installed at the bottom of the frame body 1. A rotating rod 3 is rotatably connected between the two hinge seats 2. A connecting shell 4 is fixed to the outside of the rotating rod 3. A baffle 5 is provided inside the connecting shell 4. A slider 6 is fixed to the outside of the baffle 5. The baffle 5 is slidably connected to the connecting shell 4 through the slider 6. Two connecting pieces 7 are fixed to the end of the baffle 5. Two hooks 8 are fixed to the bottom of the frame body 1. The connecting pieces 7 are connected to the hooks 8 through steel wire ropes. A positioning mechanism for positioning photovoltaic panels is provided on the frame body 1. An anti-vibration mechanism for supporting photovoltaic panels is provided inside the frame body 1. Fixing components are provided at the four corners of the frame body 1.

[0018] It should be noted that when installing the frame body 1, the steel wire rope connecting the connecting piece 7 and the hook 8 can be untied, and then the connecting shell 4 can be rotated so that the connecting shell 4 and the frame body 1 form an obtuse angle. The baffle 5 can be pulled out from the inside of the connecting shell 4 so that the connecting piece 7 contacts the ground. Then the connecting piece 7 can be bent to fit against the ground and fixed with bolts, thereby forming a flow guiding structure on the back of the frame body 1, reducing wind resistance and improving the overall wind resistance performance.

[0019] Refer to the instruction manual appendix Figure 1 , Figure 2 and Figure 4 The positioning mechanism includes a pressing component disposed on the frame body 1 and a locking component disposed on the pressing component. The pressing component is used to position the photovoltaic panel, and the locking component is used to lock the pressing component.

[0020] It should be noted that the pressing component is responsible for pressing and initially positioning the edge of the photovoltaic panel from above, while the locking component is used to fix the position of the pressing component and ensure the stability of the photovoltaic panel in the pressing state.

[0021] Refer to the instruction manual appendix Figure 1 , Figure 2 and Figure 4 The pressing assembly includes a rotating shaft 92 rotatably connected to the frame body 1, a positioning piece 91 fixed to the bottom of the rotating shaft 92, a connecting rod 93 fixed to the outside of the rotating shaft 92, and a rubber block 94 fixed to the connecting rod 93. The positioning piece 91 is in contact with the frame body 1.

[0022] It should be noted that the rotation of the pivot 92 drives the positioning plate 91, the connecting rod 93, and the rubber block 94 to work together to achieve elastic pressing and position limitation of the photovoltaic panel edge.

[0023] Refer to the instruction manual appendix Figure 1 , Figure 2 and Figure 4 The locking assembly includes a washer 95 sleeved on the outside of the rotating shaft 92 and a locking nut 96 disposed on the outside of the rotating shaft 92. The locking nut 96 is threadedly connected to the rotating shaft 92, and the washer 95 is fitted to the frame body 1.

[0024] It should be noted that the locking nut 96 is screwed onto the rotating shaft 92 by the thread, and the friction generated between the washer 95 and the frame body 1 positions the rotating shaft 92 to prevent it from loosening and springing back during use, thus ensuring the positioning is durable and reliable.

[0025] Refer to the instruction manual appendix Figure 1 and Figure 5 The seismic resistance mechanism includes an installation component installed inside the frame body 1 and a support component installed on the installation component. The installation component is used to fix the support component, and the support component is used to support the photovoltaic panel.

[0026] It should be noted that the installation components are responsible for securely connecting the entire seismic-resistant mechanism to the interior of the frame body 1, while the support components directly support the photovoltaic panels and provide necessary buffering and vibration reduction functions.

[0027] Refer to the instruction manual appendix Figure 1 and Figure 5 The installation components include a rubber frame 101 disposed inside the frame body 1, fixing screws 102 connected to the rubber frame 101, and a support plate 103 fixed inside the rubber frame 101. The rubber frame 101 is fixedly connected to the frame body 1 by the fixing screws 102.

[0028] It should be noted that the rubber frame 101 and the internal support plate 103 are firmly installed inside the frame body 1 by fixing screws 102, providing a foundation and fixing point for the support components.

[0029] Refer to the instruction manual appendix Figure 1 and Figure 5 The support assembly includes two mounting plates 104 fixed on the support plate 103, a vibration isolation plate 105 disposed on the mounting plate 104, and a rubber pad 106 connected to the vibration isolation plate 105. The rubber pad 106 is attached to the photovoltaic panel, and the vibration isolation plate 105 is wavy.

[0030] It should be noted that by utilizing the special shape (wavy) of the vibration isolation plate 105 and the elasticity of the rubber pad 106 on it, the vibration and impact transmitted from the outside to the photovoltaic panel are absorbed and attenuated, reducing stress concentration and protecting the safety of the photovoltaic panel.

[0031] Refer to the instruction manual appendix Figure 1 The fixing components include corner protectors 111 located at the four corners of the frame body 1 and positioning bolts 112 connected to the corner protectors 111. The corner protectors 111 are fixedly connected to the frame body 1 through the positioning bolts 112.

[0032] It should be noted that by using corner protectors 111 and positioning bolts 112 to reinforce and fix the four corners of the frame body 1, the connection strength and torsional resistance of the overall frame structure are significantly improved, preventing the corners from cracking or deforming under stress.

[0033] Working principle: During installation, first untie the steel wire rope between the connecting piece 7 and the hook 8, rotate the connecting shell 4 so that it forms an obtuse angle with the frame body 1, pull out the baffle 5 from the connecting shell 4 (the slider 6 slides along the connecting shell 4 as a guide), so that the connecting piece 7 contacts the ground and is bent and fixed to form a guide surface to reduce wind resistance. After the photovoltaic panel is placed, rotate the shaft 92 to drive the positioning piece 91 and the connecting rod 93 to press down, so that the rubber block 94 elastically presses the edge of the plate, and then tighten the locking nut 96 (with the washer 95) to fix the shaft 92. The rubber frame 101 inside the frame body 1 is installed by fixing screws 102. The wave-shaped vibration isolation plate 105 on its support plate 103 supports the bottom surface of the photovoltaic panel through the rubber pad 106 to absorb vibration impact. Finally, wrap the four corners of the frame with the corner protectors 111 and lock them with the positioning bolts 112 to enhance the overall torsional resistance and achieve comprehensive protection against wind and earthquake.
