Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a windproof and earthquake-resistant photovoltaic support. Background Technology

[0002] In the process of global energy structure transformation towards cleaner and lower-carbon energy, photovoltaic power generation, as one of the core applications of renewable energy, has seen its installed capacity continue to grow rapidly.

[0003] However, photovoltaic power generation systems are exposed to complex outdoor environments for a long time and must withstand multiple external stresses such as wind loads, seismic action, temperature changes, and rain and snow impacts. Among these, wind loads and seismic action are the core risk factors that lead to the failure of photovoltaic support structures and damage to components, directly affecting the safety, stability and service life of photovoltaic panels. This has gradually driven the demand for the technical research and development and application of wind-resistant and earthquake-resistant photovoltaic supports.

[0004] For example, Chinese patent CN115864977B discloses a windproof adjustable fixing bracket for photovoltaic power generation. This bracket consists of a rod, a base, a receiving block, and an installation block. The rod is circularly positioned on the base, allowing it to be fixed at different locations, reducing damage to the bracket from wind. The support frame and installation block work together to install the photovoltaic panel, utilizing grooves to secure it and increase the contact surface of the panel, thus ensuring its stability. The adjustment frame rotates the mounting frame on the support column, further reducing the impact of wind on the bracket and extending its lifespan. This also reduces the difficulty of overall installation, ensures the mounting frame and support frame remain level, and prevents the bracket from wobbling after installation.

[0005] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: The purpose of setting up photovoltaic brackets is to protect photovoltaic panels, but when facing wind loads, since the photovoltaic panels are in a fixed tilted state, the wind loads put great pressure on the structural strength of the photovoltaic panels themselves, thereby reducing the service life of the photovoltaic panels. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the photovoltaic panel is in a fixed tilt state in the prior art, which causes the wind load to put great pressure on it. To this end, we propose a windproof and earthquake-resistant photovoltaic support.

[0007] To achieve the above objectives, this application adopts the following technical solution: a windproof and earthquake-resistant photovoltaic support, including a photovoltaic panel body, a support group arranged below the photovoltaic panel body, and a sleeve fixedly installed at the lower end of the photovoltaic panel body;

[0008] The support assembly includes a support bolted to the ground, a column at the upper end of the support, a bearing rod fixedly installed on the outer wall of the column, a threaded column fixedly installed at the upper end of the bearing rod, and an adjusting component on the outer side of the threaded column.

[0009] The adjusting component includes a connecting block that is threadedly connected to the threaded column, a connecting plate that is rotatably mounted on the upper end of the connecting block, a sleeve shaft that is fixedly mounted on the upper end of the connecting plate, and a sleeve that is movably sleeved on the outside of the sleeve shaft.

[0010] Preferably, sleeves are fixedly installed at the four lower corners of the photovoltaic panel body, and threaded posts are fixedly installed at the four upper corners of the support rod.

[0011] Preferably, each of the multiple sets of threaded columns has an adjusting element on its outer side, and the multiple sets of adjusting elements have the same structural composition.

[0012] Preferably, a tapered plate is fixedly installed on the outer wall of the bearing rod, and the tapered plate is horizontally positioned with respect to the bearing rod.

[0013] Preferably, the column is slidably inserted into the inner side of the support, a fixing plate is fixedly installed on the inner wall of the column, a spring is fixedly installed at the lower end of the fixing plate, and the lower end of the spring is fixedly connected to the support.

[0014] Preferably, a damper is provided on the inner side of the spring. The damper includes a cavity cylinder that is fixedly connected to the support. The inner wall of the cavity cylinder is filled with a medium. A support rod is slidably installed on the inner side of the cavity cylinder. The upper end of the support rod is fixedly connected to the fixed plate, and a through-hole plate is fixedly installed on the lower end of the support rod.

[0015] Technical effects of this utility model:

[0016] Rotating the connecting block will cause the connecting plate and the sleeve shaft to rise in a straight line. At the same time, the sleeve will rotate with the sleeve shaft, thereby lifting one side of the photovoltaic panel body and making it tilted as a whole.

[0017] When the photovoltaic panel body and support assembly are affected by wind, the connecting plate and sleeve shaft can be driven to descend in a straight line simply by rotating the connecting block in the opposite direction.

[0018] Advantages of this utility model:

[0019] By tilting the entire structure, some light is avoided from being reflected off the surface of the photovoltaic panel, allowing sunlight to strike the photovoltaic panel's light-receiving surface as perpendicularly as possible, thus significantly improving power generation efficiency.

[0020] This allows the photovoltaic panel to return to a horizontal position, effectively reducing the area affected by wind load and wind resistance, and reducing the impact of wind on the photovoltaic panel. This improves the stability of the support structure in strong wind environments, reduces the risk of structural damage to the photovoltaic panel caused by wind load, and extends the service life of the photovoltaic panel.

[0029] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0030] In existing technologies, because photovoltaic panels are in a fixed, tilted state, they are easily subjected to significant stress on their structural strength when facing wind loads, thereby reducing their service life. (Refer to...) Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a windproof and earthquake-resistant photovoltaic support, including a photovoltaic panel body 1, a support group 2 is arranged below the photovoltaic panel body 1, and a sleeve 11 is fixedly installed at the lower end of the photovoltaic panel body 1;

[0031] The support assembly 2 includes a support 21 that is bolted to the ground. A column 22 is provided at the upper end of the support 21. A bearing rod 24 is fixedly installed on the outer wall of the column 22. A threaded column 26 is fixedly installed at the upper end of the bearing rod 24. An adjusting component 27 is provided on the outer side of the threaded column 26.

[0032] The adjusting component 27 includes a connecting block 271 threadedly connected to the threaded post 26. A connecting plate 272 is rotatably mounted on the upper end of the connecting block 271, and a sleeve shaft 273 is fixedly mounted on the upper end of the connecting plate 272. A sleeve 11 is movably sleeved on the outside of the sleeve shaft 273. During daily use, because the connecting block 271 is threadedly connected to the threaded post 26, rotating the connecting block 271 will cause the connecting plate 272 and the sleeve shaft 273 to rise linearly. At the same time, the sleeve 11 will rotate with the sleeve shaft 273, thereby lifting one side of the photovoltaic panel body 1, making it tilted as a whole, avoiding... By preventing some light from being reflected by the surface of the photovoltaic panel, the sunlight can be incident on the photovoltaic panel surface as perpendicularly as possible, significantly improving power generation efficiency. When the photovoltaic panel body 1 and the support group 2 are affected by wind, the connecting plate 272 and the sleeve shaft 273 can be driven to descend in a straight line by simply rotating the connecting block 271 in the opposite direction, thereby causing the photovoltaic panel body 1 to return to a horizontal state. This effectively reduces the area affected by wind load and wind resistance, reduces the impact force of wind on the photovoltaic panel, thereby improving the stability of the support in strong wind environments, reducing the risk of structural damage to the photovoltaic panel caused by wind load, and extending the service life of the photovoltaic panel.

[0033] In order to further improve the stability of support assembly 2 during use, refer to Figure 1 - Figure 4 As shown in this embodiment: sleeves 11 are fixedly installed at the four lower corners of the photovoltaic panel body 1, and threaded posts 26 are fixedly installed at the four upper corners of the bearing rod 24. This can effectively avoid the problem of local stress concentration and ensure that the photovoltaic panel is in a balanced state of stress at each connection point during static support or dynamic adjustment, thereby reducing the risk of frame deformation and component cracking.

[0034] Reference Figure 1 - Figure 4 As shown in this embodiment, an adjusting component 27 is provided on the outer side of each of the multiple sets of threaded columns 26. The multiple sets of adjusting components 27 have the same structure, so that the photovoltaic panel can be adjusted on any side according to the usage requirements during actual use, thereby enhancing its practicality.

[0035] Reference Figure 3As shown in this embodiment: a conical plate 25 is fixedly installed on the outer wall of the support rod 24. The conical plate 25 is horizontally arranged with the support rod 24. The conical plate 25 can guide some of the lateral airflow to diffuse downward or to the side, which can effectively reduce the windward area of ​​the support rod 24, avoid the airflow from directly impacting the support, and further reduce the impact of wind load on the photovoltaic panel and the support.

[0036] Reference Figure 5 As shown in this embodiment: the column 22 is slidably inserted into the inner side of the support 21, and a fixing plate 23 is fixedly installed on the inner wall of the column 22. A spring 231 is fixedly installed at the lower end of the fixing plate 23. The lower end of the spring 231 is fixedly connected to the support 21. When the column 22 is subjected to longitudinal force, such as longitudinal impact of an earthquake or the self-weight of the photovoltaic panel, the spring 231 can undergo compression or stretching deformation as the column 22 slides, converting the rigid impact force into elastic potential energy, thereby playing a buffering role.

[0037] In actual use, the buffering effect of spring 231 is very prone to resonance with vibration. To avoid this situation, refer to... Figure 5 - Figure 6 As shown in this embodiment: a damper 233 is provided inside the spring 231. The damper 233 includes a cavity cylinder 2331 fixedly connected to the support 21. The inner wall of the cavity cylinder 2331 is filled with a medium. A support rod 2332 is slidably installed inside the cavity cylinder 2331. The upper end of the support rod 2332 is fixedly connected to the fixed plate 23. A through-hole plate 2333 is fixedly installed at the lower end of the support rod 2332, so that the through-hole plate 2333 and the support rod 2332 can move synchronously with the fixed plate 23, allowing the medium to pass through the through-hole plate 2333, thereby activating the damping effect and avoiding resonance. Liquid is recommended as the medium.

[0038] Working principle: During daily use, since the connecting block 271 is threadedly connected to the threaded post 26, rotating the connecting block 271 will cause the connecting plate 272 and the sleeve shaft 273 to rise linearly. At the same time, the sleeve 11 will rotate with the sleeve shaft 273, thereby lifting one side of the photovoltaic panel body 1 and making it tilted. This prevents some light from being reflected by the photovoltaic panel surface, allowing sunlight to enter the photovoltaic panel's light-receiving surface as perpendicularly as possible, significantly improving power generation efficiency. When the photovoltaic panel body 1 and the support assembly 2 are affected by wind, simply rotating the connecting block 271 in the opposite direction will cause the connecting plate 272 and the sleeve shaft 273 to fall linearly, thereby causing the photovoltaic panel body 1 to return to a horizontal state. This effectively reduces the area affected by wind load and wind resistance, reduces the impact of wind on the photovoltaic panel, thereby improving the stability of the support in strong wind environments, reducing the risk of structural damage to the photovoltaic panel caused by wind load, and extending the service life of the photovoltaic panel.

[0039] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
