Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel support technology, specifically a wind-pressure resistant photovoltaic panel support. Background Technology

[0002] With the global energy crisis and environmental pollution becoming increasingly serious, solar energy, as a clean and renewable energy source, has received widespread attention. Among them, photovoltaic panels, as one of the key components of solar power generation, have been widely used in various occasions. However, photovoltaic panels often face the impact of severe weather conditions in actual use, especially damage caused by strong winds. This not only affects the normal operation of photovoltaic systems but may also cause serious economic losses. Therefore, how to design a photovoltaic panel support that can effectively resist wind pressure has become the focus of current research.

[0003] Currently, fixed supports improve rigidity and stability by increasing their height and thickness, thereby enhancing wind resistance. Their advantages include simple structure and low cost. However, they are prone to resonance under extreme wind speeds, leading to deformation or even breakage. Adjustable supports allow photovoltaic panels to adjust their angle with the wind direction, reducing the windward area. Their advantages include dynamic adaptation to different wind conditions and reduced wind load. However, they increase system complexity and maintenance costs. Damper-mounted solutions involve installing dampers on the supports to absorb some vibration energy and reduce wind-induced impact. Their advantages include good suppression of wind vibrations of different frequencies. However, their disadvantages include higher initial investment and the need for regular inspection and replacement of damping components.

[0004] Although the above-mentioned solutions have improved the wind resistance of photovoltaic panel supports to some extent, they still have some common problems. First, although the fixed support has a simple structure, it is difficult to maintain stability under extreme wind speed conditions and is prone to damage. Although the adjustable support can dynamically adjust the angle, the complex mechanism makes the maintenance cost increase significantly. In addition, although the damper installation solution can effectively absorb vibration energy, the high cost limits its application scope. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wind-pressure resistant photovoltaic panel support that achieves efficient wind pressure resistance while ensuring the structural strength of the photovoltaic panel support, extending its service life, reducing costs, and simplifying the maintenance process. It solves the problems of fixed supports, which, although simple in structure, are difficult to maintain stability under extreme wind speed conditions and are prone to damage; adjustable supports, although capable of dynamically adjusting the angle, have complex mechanisms that significantly increase maintenance costs; and damper installation schemes, while effectively absorbing vibration energy, have high costs that limit their widespread application.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wind-resistant photovoltaic panel support, comprising a ground, a photovoltaic panel body, and a main frame, characterized in that: the inner peripheral wall of the main frame is provided with a wind-resistant mechanism, the lower surface of the main frame is provided with a buffer block, and the lower surface of the buffer block is provided with a fixing plate;

[0007] The wind-resistant mechanism includes at least two connecting rods, a sub-frame, four windbreaks, four reinforcing bars, and a windbreak frame.

The four windbreaks are all installed and fixed around the main frame. The four reinforcing bars are all installed at the four corners of the lower surface of the main frame. The windbreak frame is installed on the upper surface of the main frame. The photovoltaic panel body is installed on the bottom wall of the inner cavity of the windbreak frame.

[0012] By adopting this technical solution, the structural strength of the sub-frame can be improved by setting no fewer than two reinforcing plates inside the sub-frame.

[0013] Furthermore, the buffer block is a rubber block.

[0014] By adopting this technical solution, the buffer block can be compressed to absorb energy, while also having anti-corrosion properties, thus improving the seismic performance of the support.

[0015] Furthermore, the buffer block is located on the longitudinal central axis of the main frame.

[0016] By adopting this technical solution, the stability of the buffer block fixed to the lower surface of the main frame is improved. The buffer block can absorb the energy generated by earthquakes or other unexpected impacts, thereby improving the seismic performance of the support.

[0017] Furthermore, both the main frame and the sub-frame are made of high-strength aluminum alloy and have a rectangular structure.

[0018] By adopting this technical solution, the main frame and the sub-frame can distribute and bear most of the wind load, preventing excessive local stress from causing the support to deform or break.

[0019] Furthermore, the fixing plate is a high-strength aluminum alloy plate.

[0020] By adopting this technical solution, the bracket can be supported by a fixing plate. The fixing plate is made of high-strength aluminum alloy, which can improve the stability and strength of the structure.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The inner peripheral wall of the main frame 3 is provided with a wind-resistant mechanism 4. The wind-resistant mechanism 4 ensures the structural strength of the photovoltaic panel support while achieving efficient wind pressure resistance, extending service life, reducing costs, and simplifying the maintenance process. A buffer block 5 is provided on the lower surface of the main frame 3, and a fixing plate 6 is provided on the lower surface of the buffer block 5.

[0031] In this embodiment, the frame is provided with no fewer than two reinforcing plates inside, and the buffer block 5 is a rubber block located on the longitudinal central axis of the main frame 3.

[0032] It should be noted that buffer block 5 can absorb the energy generated by earthquakes or other unexpected impacts, thereby improving the seismic performance of the support structure.

[0033] Please see Figures 2 to 3 In order to ensure the structural strength of the photovoltaic panel support while achieving efficient wind pressure resistance, extending service life, reducing costs, and simplifying maintenance, the wind-resistant mechanism 4 in this embodiment includes at least two connecting rods 41, a sub-frame 42, four windproof baffles 43, four reinforcing steel bars 44, and a windbreak frame 45. The at least two connecting rods 41 are all set on the inner peripheral wall of the main frame 3.

[0034] In this embodiment, the sub-frame 42 is set on one side opposite to at least two connecting rods 41, four windproof baffles 43 are installed and fixed around the main frame 3, four reinforcing steel bars 44 are set at the four corners of the lower surface of the main frame 3, the windproof frame 45 is set on the upper surface of the main frame 3, the photovoltaic panel body 2 is set on the bottom wall of the inner cavity of the windproof frame 45, the bottom ends of the four reinforcing steel bars 44 are fixed to the inside of the upper surface of the ground 1 by concrete pouring, the lower surface of the fixing plate 6 is in contact with the upper surface of the ground 1, and the fixing plate 6 can support the main frame 3 and improve the stability of the bracket.

[0035] In this embodiment, under strong wind conditions, the wind will exert significant pressure on the photovoltaic panel body 2. At this time, the multi-layer structure of the main frame 3 and the sub-frame 42 can disperse and bear most of the wind load, preventing excessive local stress from causing deformation or breakage of the support. The design of at least two connecting rods 41 ensures the stability of the connection between the main frame 3 and the sub-frame 42, preventing loosening due to vibration. The four reinforcing steel bars 44 provide additional support, making the support more robust. The sub-frame 42 is installed sequentially inside the main frame 3, ensuring that all components are tightly attached and neatly arranged. The four reinforcing steel bars 44 provide additional support for the support, making it more robust, sturdy, durable, and wind-resistant.

[0036] In this embodiment, the four windproof baffles 43 are all polycarbonate composite material plates, the sub-frame 42 includes a frame body, the main frame 3 and the sub-frame 42 are both made of high-strength aluminum alloy and have a rectangular structure, the fixing plate 6 is a high-strength aluminum alloy plate, and the connecting rods 41, which number no less than two, are all stainless steel rods. The outer side of the four windproof baffles 43 is coated with a layer of nano self-cleaning coating, which enables the four windproof baffles 43 to have waterproof and dustproof functions, reduce the number of daily maintenance, and extend the service life. The photovoltaic panel body 2 is set on the bottom wall of the inner cavity of the windproof frame 45, and the windproof frame 45 can block the wind for the photovoltaic panel body 2, thereby improving the stability of the photovoltaic panel body 2 under high wind conditions.

[0037] In this embodiment, the main frame 3 and sub-frame 42 can be selected with different materials and thicknesses according to the climate characteristics of different regions and customer needs. For example, in coastal areas, stainless steel with strong corrosion resistance can be selected. For low wind speed environments, thinner reinforcing ribs or fewer wind deflectors 43 can be selected to reduce costs. The four wind deflectors 43 can be made of polycarbonate composite material with a thickness of about 3mm and the width is determined according to the size of the main frame 3. The four reinforcing steel bars 44 are made of Q235 carbon steel with a diameter of not less than 20mm and a height of not less than 1.5m. The connecting rods 41, which are not less than two in number, can be made of 304 stainless steel with M12 bolts and matching nuts, and there are not less than four of them. The main frame 3 is made of 6061-T6 aluminum alloy with a wall thickness of not less than 5mm and the length is customized according to actual needs.

[0038] In this embodiment, the wind pressure resistance of the photovoltaic panel support is improved, and it can remain stable even under extreme wind speed conditions, reducing the failure rate and maintenance costs. By optimizing the structural design and material selection, the overall rigidity and durability of the support are enhanced, the service life is extended, the installation and maintenance process is simplified, the manual burden is reduced, and the work efficiency is improved.

[0039] It should be noted that the windbreak 43, made of a material with good aerodynamic properties, can effectively guide airflow around the photovoltaic panel, reducing the wind pressure acting directly on it, thereby protecting the photovoltaic panel body 2 from damage. When selecting a suitable installation location for the installation bracket, ensure that the ground 1 is flat and firm, avoiding soft soil or areas prone to water accumulation. Four reinforcing steel bars 44 can be inserted into the holes on the surface of the ground 1 and fixed with concrete. The windbreak 43, which is fixed around the main frame 3, has a smooth and seamless surface and good edge sealing, reducing the impact of wind pressure on the photovoltaic panel.

[0040] The working principle of the above embodiments is as follows:

[0041] In strong winds, the wind exerts significant pressure on the photovoltaic panel body 2. The multi-layered structure of the main frame 3 and sub-frame 42 disperses and bears most of the wind load, preventing excessive local stress that could lead to deformation or breakage of the support structure. The design of at least two connecting rods 41 ensures the stability of the connection between the main frame 3 and sub-frame 42, preventing loosening due to vibration. Four reinforcing steel bars 44 provide additional support, making the support structure more robust. The windbreak 43, made of a material with excellent aerodynamic properties, effectively guides airflow around the photovoltaic panel, reducing the direct wind pressure and protecting the photovoltaic panel body 2 from damage. A suitable installation location is chosen, ensuring the ground 1 is flat and firm, avoiding soft soil or areas prone to water accumulation. The four reinforcing steel bars 44 can be inserted into holes on the surface of the ground 1 and fixed with concrete. The windbreak 43, with its smooth, seamless surface and well-sealed edges, is installed around the main frame 3.
