Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic brackets, and in particular to a wind-resistant and shock-absorbing photovoltaic bracket. Background Technology
[0002] With the rapid development of solar photovoltaic (PV) power generation technology, PV mounting systems, as crucial components supporting solar PV panels, significantly impact the stability and reliability of PV power generation systems. In practical applications, PV mounting systems are frequently affected by severe weather conditions such as strong winds. Strong winds can easily cause significant swaying and vibration of the PV mounting systems, not only reducing the power generation efficiency of the PV panels but also potentially damaging the structure of the mounting systems and even causing safety accidents. Furthermore, in earthquake-prone areas, the vibrations from earthquakes can also adversely affect PV mounting systems. Currently, PV mounting systems on the market have certain shortcomings in wind resistance and vibration damping, making it difficult to meet the growing demands of use. Therefore, there is an urgent need to improve the structure of PV mounting systems to enhance their wind resistance and vibration damping performance. Utility Model Content
[0003] The present invention aims to provide a wind-resistant and shock-absorbing photovoltaic support, which solves the problem of poor wind resistance and shock absorption in the existing technology.
[0004] This solution provides a wind-resistant and vibration-damping photovoltaic support, including a base and a photovoltaic panel mounting frame. The base is equipped with a support column, and a first adjustment frame and a second adjustment frame are slidably and bolted to the support column. The first adjustment frame is bolted to a first adjustment rod, and a crossbeam is fixedly connected to the second adjustment frame. The end of the crossbeam is hinged to the second adjustment rod, and the other end of the second adjustment rod is hinged to the support column. An elastic element is provided between the crossbeam and the second adjustment rod. The bottom of the photovoltaic panel mounting frame is hinged to the support column, and the bottom of the photovoltaic panel mounting frame is bolted to the first adjustment rod.
[0005] The working principle and beneficial effects of this solution are as follows: First, determine the optimal tilt angle of the photovoltaic panel based on local sunlight conditions and seasonal changes. Loosen the bolts securing the first adjustment frame, slide the first adjustment frame up and down along the support column, moving the first adjustment rod. The first adjustment rod is hinged to the photovoltaic panel mounting frame. As the position of the first adjustment frame changes, the tilt angle of the first adjustment rod changes accordingly. Once the photovoltaic panel mounting frame reaches the preset tilt angle, tighten the bolts to fix the first adjustment frame to the support column, and simultaneously fix the connection end between the first adjustment rod and the first adjustment frame / photovoltaic panel mounting frame, completing the precise adjustment of the initial angle of the photovoltaic panel. Adjusting the tilt angle of the photovoltaic panel by using the first adjustment frame and the first adjustment rod changes the size of the photovoltaic panel's windward surface. Before strong winds arrive, adjusting the photovoltaic panel angle to be more parallel to the wind direction reduces the frontal windward area, lowers the direct thrust of the wind on the photovoltaic panel, and thus reduces the wind load borne by the overall support structure. For example, in coastal areas with strong winds, reducing the photovoltaic panel angle to make the panel surface nearly horizontal can significantly reduce wind resistance. During strong winds, the wind pushes the photovoltaic panel mounting frame, causing the supports and beams to sway. The second adjusting rod, hinged to the end of the beam, tends to rotate around the hinge point, changing the angle between it and the beam, compressing or stretching the elastic element between them. The elastic element absorbs the impact energy of the wind through deformation and uses its elastic restoring force to suppress the swaying of the supports and beams. If the wind force continues to change, the fixing bolts between the second adjusting frame and the support can be loosened, and the second adjusting frame can be slid to adjust the angle between the second adjusting rod and the beam. Through the buffering characteristics of the elastic element, the support structure can adapt to different wind forces, reducing structural vibration.
[0006] The sliding and bolted connections between the support column and the first adjusting frame and the first adjusting rod, combined with the hinged design of the photovoltaic panel mounting frame, allow for precise adjustment of the photovoltaic panel tilt angle, improving light energy reception efficiency. The second adjusting frame, the second adjusting rod, and the elastic element work together. In strong winds, the elastic element absorbs impact energy through deformation, suppressing the swaying of the support. The adjustable angle between the second adjusting rod and the crossbeam allows the support to adapt to different wind forces, enhancing wind resistance. The combination of sliding, hinged, and bolted connections between the components ensures both flexibility in the adjustment process and structural stability, reducing the risk of component loosening due to vibration, extending the service life of the photovoltaic support and photovoltaic panels, simplifying installation and maintenance processes, reducing overall costs, and demonstrating significant practical value and market competitiveness.
[0007] Furthermore, the elastic element includes a fixed block, with a limiting rod fixedly connected to the fixed block. A spring is sleeved on the limiting rod, and a limiting plate passes through the bottom of the limiting rod. The end of the fixed block is hinged to the second adjusting rod. A groove is provided on the crossbeam, and the limiting rod is slidably connected within the groove. The rigid connection between the fixed block and the limiting rod provides a stable base for the elastic element. The hinged connection of the fixed block to the second adjusting rod allows the fixed block to rotate synchronously when the second adjusting rod swings under wind force, ensuring smooth force transmission. The sliding fit between the limiting rod and the groove on the crossbeam allows the limiting rod to have displacement space when the spring undergoes elastic deformation, precisely constraining horizontal displacement and eliminating the risk of loose connection. Under strong winds, the controllable sliding of the limiting rod within the groove ensures that the elastic element fully deforms and dissipates energy, while also preventing structural misalignment and failure, significantly improving the reliability of the wind-resistant and vibration-damping system.
[0008] Furthermore, the bottom of the limiting plate is provided with a shock-absorbing rubber pad, and the limiting rod passes through the shock-absorbing rubber pad into the groove. When the wind-driven components move, the rubber pad effectively buffers the rigid collisions between metals, which not only significantly reduces component wear and noise, but also dissipates instantaneous impacts, avoids overload damage to elastic components, and extends the life of the core components of the photovoltaic bracket from the root.
[0009] Furthermore, there are two elastic elements, one near the included angle and the other near the opening. The two near-angle elastic elements quickly lock the angle during strong wind compression, preventing structural damage; the near-opening elastic element strongly pulls back during wind stretching, preventing components from loosening. The two elements work together to respond to changes in wind direction and force, allowing the support structure to maintain precise angle control even in extreme wind conditions, ensuring stable support for the continuous operation of the photovoltaic panels.

[0011] The reference numerals in the accompanying drawings include: base 1, support column 2, first adjustment frame 3, crossbeam 4, second adjustment rod 5, fixing block 6, spring 7, limiting plate 8, shock-absorbing rubber pad 9, second adjustment frame 10, first adjustment rod 11, photovoltaic panel mounting frame 12, and photovoltaic panel 13. Detailed Implementation
[0012] The following detailed explanation illustrates the specific implementation methods:
[0013] The basic implementation examples are as follows: Figure 1As shown: A wind-resistant and vibration-damping photovoltaic support includes a base 1 and a photovoltaic panel mounting frame 12. A support column 2 is bolted to the base 1. A first adjusting frame 3 and a second adjusting frame 10 are slidably bolted to the support column 2. A first adjusting rod 11 is bolted to the first adjusting frame 3. A crossbeam 4 is fixedly connected to the second adjusting frame 10. A second adjusting rod 5 is hinged to one end of the crossbeam 4. The other end of the second adjusting rod 5 is hinged to the support column 2. Two elastic elements are provided between the crossbeam 4 and the second adjusting rod 5. One elastic element is near the included angle, and the other elastic element is near the opening. The bottom of the photovoltaic panel mounting frame 12 is hinged to the support column 2, and the bottom of the photovoltaic panel mounting frame 12 is bolted to the first adjusting rod 11.
[0014] The elastic element includes a fixed block 6, which is fixedly connected to a limiting rod. A spring 7 is sleeved on the limiting rod, and a limiting piece 8 passes through the bottom of the limiting rod. The end of the fixed block 6 is hinged to the second adjusting rod 5. A groove is provided on the crossbeam 4, and the limiting rod is slidably connected in the groove. A shock-absorbing rubber pad 9 is provided at the bottom of the limiting piece 8, and the limiting rod passes through the shock-absorbing rubber pad 9 into the groove.
[0015] The photovoltaic panel 13 is installed on the photovoltaic panel mounting frame 12. Before use, the optimal tilt angle of the photovoltaic panel 13 is determined based on local sunlight conditions and seasonal changes. The bolts securing the first adjusting frame 3 are loosened, and the first adjusting frame 3 is slid up and down along the support column 2, causing the first adjusting rod 11 to move. The first adjusting rod 11 is hinged to the photovoltaic panel mounting frame 12. As the position of the first adjusting frame 3 changes, the tilt angle of the first adjusting rod 11 changes accordingly. When the photovoltaic panel mounting frame 12 reaches the preset tilt angle, the bolts are tightened to fix the first adjusting frame 3 to the support column 2, and the connection ends of the first adjusting rod 11 with the first adjusting frame 3 and the photovoltaic panel mounting frame 12 are simultaneously fixed, completing the precise adjustment of the initial angle of the photovoltaic panel 13. Adjusting the tilt angle of the photovoltaic panel 13 by using the first adjusting frame 3 and the first adjusting rod 11 changes the size of the windward surface of the photovoltaic panel 13. Before strong winds arrive, the angle of the photovoltaic panel 13 is adjusted to be more parallel to the wind direction, reducing the frontal windward area and decreasing the direct thrust of the wind on the photovoltaic panel 13, thereby reducing the wind load on the overall support structure. For example, in coastal areas with strong winds, adjusting the angle of the photovoltaic panel 13 to make the panel surface nearly horizontal can significantly reduce wind resistance. During strong winds, the wind pushes the photovoltaic panel mounting frame 12, causing the support column 2 and crossbeam 4 to sway. The second adjusting rod 5, hinged to the end of the crossbeam 4, tends to rotate around the hinge point, changing the angle between it and the crossbeam 4, compressing or stretching the elastic element between them. The elastic element absorbs the impact energy of the wind through deformation and uses its elastic restoring force to suppress the swaying of the support column 2 and crossbeam 4. If the wind force continues to change, the fixing bolts between the second adjusting frame 10 and the support column 2 can be loosened, and the second adjusting frame 10 can be slid to adjust the angle between the second adjusting rod 5 and the crossbeam 4. Through the buffering characteristics of the spring 7, the support structure can adapt to different wind forces, reducing structural vibration.
[0016] The angle between the second adjusting rod 5 and the crossbeam 4 directly affects the wind resistance of the support structure. Specifically: when the angle is reduced (e.g., from 60° to 30°), the initial preload of the elastic element increases, allowing for a faster response and energy absorption even in light winds, significantly suppressing minor swaying and making it suitable for areas with frequent moderate winds. When the angle is increased (e.g., from 30° to 60°), the elastic element has a larger deformation range, absorbing more energy from strong winds and preventing elastic failure due to excessive compression or stretching. This better addresses short-term strong winds or typhoons and improves the support structure's wind resistance stability in strong wind environments. This adjustable angle design allows the support structure to adapt flexibly to different wind levels, achieving dynamic optimization of wind resistance.
[0017] The sliding and bolted connections between the support column 2 and the first adjusting frame 3 and the first adjusting rod 11, combined with the hinged design of the photovoltaic panel mounting frame 12, allow for precise adjustment of the tilt angle of the photovoltaic panel 13, improving the efficiency of light energy reception. The second adjusting frame 10, the second adjusting rod 5, and the elastic element work together. In strong winds, the elastic element absorbs impact energy through deformation, suppressing the swaying of the support. The angle between the second adjusting rod 5 and the crossbeam 4 is adjustable, allowing the support to adapt to different wind forces and enhancing its wind resistance. The combination of sliding, hinged, and bolted connections between the components ensures both flexibility in the adjustment process and structural stability, reducing the risk of component loosening due to vibration, extending the service life of the photovoltaic support and photovoltaic panel 13, simplifying the installation and maintenance process, reducing overall costs, and possessing significant practical value and market competitiveness.
