Description

Technical Field

[0001] The invention relates to the field of photovoltaic technology, and in particular to a strong wind resistant photovoltaic bracket that can be used in a large photovoltaic power station. Background Art

[0002] Large-scale photovoltaic power stations usually refer to power generation systems with installed capacity ranging from tens of megawatts to hundreds of megawatts. Their construction must strictly follow multi-dimensional standards such as environmental assessment, land use, and design to ensure that both environmental protection and performance meet the standards. This type of power station covers a large area, has a large investment scale, has a significant scale effect, can reduce the cost of unit electricity, and is usually connected to a high-voltage power grid for power transmission. Large-scale photovoltaic power stations use solar energy, a renewable energy source, which is environmentally friendly, low-cost, highly stable, and highly flexible. In the operation stage, large-scale photovoltaic power stations focus on cost control, efficiency improvement, and safety assurance, and achieve long-term stable operation by optimizing technology and maintenance strategies. At the same time, they also benefit from the support of national policies and regulations, especially in terms of safety, environmental protection, and electricity safety, and need to be subject to regular reviews to ensure compliance operations. In the future, with the advancement of technology and the reduction of costs, large-scale photovoltaic power stations will occupy a more important position in the energy structure and make important contributions to the development of global renewable energy.

[0003] The wind-resistant photovoltaic bracket used in large photovoltaic power stations is a special structure designed to improve the stability and safety of photovoltaic systems under severe wind conditions. This type of bracket is usually made of high-strength, corrosion-resistant materials, such as high-quality steel or aluminum alloy, to ensure that the structural integrity can be maintained under extreme wind pressure and dynamic loads. In terms of design, the wind-resistant bracket will adopt a more stable geometric configuration, such as adding beams, diagonal braces or a streamlined design with less wind resistance, to effectively disperse and resist wind force and reduce wind vibration effects. In addition, the foundation of the bracket will also be specially reinforced, by deep burial, expanding the foundation area or using special anchoring technology to ensure that the bracket is firmly fixed to the ground and can remain stable even in strong winds. The application of this bracket not only improves the wind resistance of photovoltaic power stations, reduces the risk of equipment damage caused by wind disasters, but also extends the service life of photovoltaic systems, providing a strong guarantee for the long-term stable operation of large photovoltaic power stations.

[0004] When using a photovoltaic bracket, it is necessary to ensure the effectiveness of the use of the photovoltaic bracket and improve the stability of the photovoltaic bracket. However, we take into account that the traditional photovoltaic bracket has a single functionality and cannot be adjusted according to the wind direction, which causes the photovoltaic panel to be subject to large wind resistance, thereby affecting the overall stability of the photovoltaic bracket, which is extremely inconvenient. Therefore, there is an urgent need for a strong wind-resistant photovoltaic bracket that can be used in large photovoltaic power stations to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a strong-wind-resistant photovoltaic bracket that can be used in large photovoltaic power stations, which solves the problem that the photovoltaic brackets in the prior art have a single functionality and cannot be adjusted according to wind direction, thereby causing large wind resistance on the photovoltaic panels, which in turn affects the overall stability of the photovoltaic bracket.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A strong wind resistant photovoltaic bracket that can be used in large photovoltaic power stations comprises a base, a bearing plate is provided on the top of the base, and a photovoltaic panel is fixedly connected to the top of the bearing plate, an annular plate is fixedly connected to the top of the base, and the side wall of the bearing plate is slidably connected to the annular plate, the bearing plate is located on the inner side of the annular plate, one side of the bottom of the base is fixedly connected to a driving motor by bolts, a rotating rod is fixedly connected to the bottom of the bearing plate, and the bottom end of the rotating rod passes through the bearing plate and is drivingly connected to the output shaft of the driving motor, plug plates are fixedly connected to both sides of the bottom of the base, and the tops of the two plug plates are fixedly connected by a connecting plate, hydraulic cylinders are fixedly connected to both sides of the top of the base by bolts, and the output shafts of the two hydraulic cylinders pass through the base, and the output shafts of the two hydraulic cylinders are fixedly connected to the top of the connecting plate.

[0008] Preferably, a plurality of sliders are fixedly connected to the side wall of the bearing plate around one circumference, and all the sliders are slidably connected to the annular plate via the annular groove.

[0009] Preferably, the two plug plates are symmetrically distributed along the center of the base, and the connections between the output shafts of the two hydraulic cylinders and the base are all sliding connections.

[0010] Preferably, the photovoltaic panels are distributed in an inclined manner, and the bottom ends of the photovoltaic panels are located on the inner side of the annular plate.

[0011] Preferably, all the sliding blocks are clearance-fitted with the annular grooves.

[0012] Preferably, threaded rods are provided at the top of the annular plate near all the sliders, and threaded grooves matching the threaded rods are provided at the top of the annular plate and the tops of all the sliders, and there are several threaded grooves at the top of the annular plate.

[0013] The present invention has the following beneficial effects:

[0014] The present invention proposes a practical solution to the problem that traditional photovoltaic brackets have single functionality and cannot be adjusted according to wind direction. By using a driving motor in conjunction with a rotating rod, the direction of the photovoltaic panel can be flexibly adjusted. This function significantly reduces the wind resistance of the photovoltaic panel under severe wind conditions, thereby improving the overall stability of the photovoltaic bracket. This not only effectively avoids the risk of equipment damage caused by excessive wind resistance, but also greatly extends the service life of the photovoltaic system. In addition, the introduction of the hydraulic cylinder provides additional stability support for the bracket. Under extreme wind conditions, the hydraulic cylinder can respond quickly, and by adjusting the extension length of its output shaft, the base part of the bracket is further reinforced to ensure that the bracket is firmly fixed in strong wind weather. The design of this dual stability mechanism not only improves the wind resistance of the photovoltaic power station, but also provides a strong guarantee for the long-term stable operation of large photovoltaic power stations. In summary, the anti-strong wind photovoltaic bracket effectively solves the problem of insufficient stability of traditional photovoltaic brackets under severe wind conditions through its unique design and work process, improves the safety and reliability of the photovoltaic system, and makes important contributions to the environmental protection, high efficiency and stable operation of large photovoltaic power stations.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Reference Figure 1-5 , a wind-resistant photovoltaic bracket that can be used in a large photovoltaic power station, includes a base 1, a bearing plate 8 is provided on the top of the base 1, and the top of the bearing plate 8 is tightly fixedly connected to the photovoltaic panel 7, which is a key component for direct support and angle adjustment of the photovoltaic panel 7. The sliding connection design between the bearing plate 8 and the annular plate 9 enables the bearing plate 8 to flexibly rotate inside the annular plate 9, thereby adjusting the orientation of the photovoltaic panel 7 according to the wind direction, reducing wind resistance, and improving power generation efficiency. The top of the bearing plate 8 is fixedly connected with the photovoltaic panel 7. As a core component of photoelectric conversion, its inclined distribution is not only conducive to receiving more sunlight and improving power generation efficiency, but also can reduce the direct impact of wind on the photovoltaic panel 7 by adjusting the orientation when the wind conditions change, and further protect the photovoltaic panel 7 from damage. The top of the base 1 is fixedly connected with the annular plate 9, which is slidably connected to the bearing plate 8, providing guidance and support for the rotation of the bearing plate 8. The design of the annular plate 9 not only enhances the overall structural strength of the bracket, but also through the annular groove 11 on its inner side and the slider 10 on the bearing plate 8 The cooperation realizes the smooth and low-friction rotation of the bearing plate 8, and the side wall of the bearing plate 8 is slidingly connected to the annular plate 9. The bearing plate 8 is located on the inner side of the annular plate 9. One side of the bottom of the base 1 is fixedly connected to the driving motor 4 by bolts. The bottom of the bearing plate 8 is fixedly connected to the rotating rod 5, and the bottom end of the rotating rod 5 passes through the bearing plate 8 and is transmission-connected to the output shaft of the driving motor 4. Both sides of the bottom of the base 1 are fixedly connected with the plug plates 2. The plug plates 2 are symmetrically distributed along both sides of the bottom of the base 1, and together with the connecting plate 3 constitute a stable supporting structure of the bracket. The design of the plug plates 2 not only enhances the wind resistance of the bracket, but also forms a stable triangular supporting structure through its fixed connection with the connecting plate 3, further improving the overall stability of the bracket. The tops of the two plug plates 2 are fixedly connected by the connecting plate 3, and both sides of the top of the base 1 are fixedly connected with the hydraulic cylinders 6 by bolts, and the output shafts of the two hydraulic cylinders 6 pass through the base 1, and the output shafts of the two hydraulic cylinders 6 are fixedly connected to the top of the connecting plate 3.

[0024] In large photovoltaic power stations, the anti-strong wind photovoltaic bracket adopted achieves efficient and stable operation through a series of exquisite designs. Specifically, when it is necessary to adjust the orientation of the photovoltaic panel 7 to cope with different wind directions, the drive motor 4 fixedly connected to one side of the bottom of the base 1 is first started. The operation of the drive motor 4 drives the rotating rod 5 connected to it to start rotating. Since the top of the rotating rod 5 is fixedly connected to the bottom of the bearing plate 8, the bearing plate 8 will slide and rotate on the inner side of the annular plate 9, thereby adjusting the orientation of the photovoltaic panel 7 fixedly connected to the top of the bearing plate 8. This process realizes the flexible adjustment of the photovoltaic panel 7 according to the wind direction and effectively reduces the wind resistance. At the same time, in order to further enhance the stability of the photovoltaic bracket, plug plates 2 are provided on both sides of the bottom of the base 1, and fixed connection is achieved through the connecting plate 3 to form a stable support structure. When facing extreme wind conditions, the hydraulic cylinder 6 fixedly connected to the bolts on both sides of the bottom of the base 1 can be controlled to extend its output shaft upward, further shortening the distance between the connecting plate 3 and the base 1, thereby enhancing the wind pressure resistance of the entire bracket through the synergistic effect of the plug plate 2 and the connecting plate 3, and ensuring the stability of the photovoltaic panel 7 and the bracket structure.

[0025] Furthermore, a plurality of sliders 10 are fixedly connected to the side wall of the supporting plate 8, and all the sliders 10 are slidably connected to the annular plate 9 via the annular groove 11. By means of the plurality of sliders 10 fixedly connected to the side wall of the supporting plate 8 and the annular groove 11 opened on the annular plate 9, the sliders 10 are slidably connected to the annular groove 11. When the supporting plate 8 slides and rotates inside the annular plate 9, the sliders 10 slide along the annular groove 11, thereby playing a guiding and supporting role, thereby achieving the effect of making the rotation of the supporting plate 8 more stable and reducing friction loss.

[0026] Furthermore, the two plug plates 2 are symmetrically distributed along the center of the base 1, and the connections between the output shafts of the two hydraulic cylinders 6 and the base 1 are all sliding connections. The two plug plates 2 are symmetrically distributed along the center of the base 1. This symmetrical distribution design enables the bracket to disperse the pressure more evenly when subjected to force, thereby achieving the effect of enhancing the overall structural stability of the bracket and improving the wind resistance. The output shafts of the two hydraulic cylinders 6 are all slidingly connected to the base 1. When the output shafts of the hydraulic cylinders 6 are extended or retracted, the distance between them and the connecting plate 3 can be more flexibly adjusted, thereby achieving the effect of enabling the bracket to respond quickly and enhance stability when dealing with different wind conditions.

[0027] Furthermore, the photovoltaic panel 7 is distributed in an inclined manner, and the bottom end of the photovoltaic panel 7 is located on the inner side of the annular plate 9. The photovoltaic panel 7 is distributed in an inclined manner, and the bottom end of the photovoltaic panel 7 is located on the inner side of the annular plate 9. This inclined distribution is not only beneficial for the photovoltaic panel 7 to better receive sunlight, but also can reduce the direct impact of wind on the photovoltaic panel 7 when the wind conditions change, thereby achieving the effect of improving the power generation efficiency of the photovoltaic panel 7 and reducing wind resistance.

[0028] Furthermore, all the sliders 10 and the annular grooves 11 are clearance-fitted.

[0029] Furthermore, threaded rods 12 are provided at the top of the annular plate 9 near all the sliders 10, and threaded grooves 13 matching the threaded rods 12 are provided at the top of the annular plate 9 and the tops of all the sliders 10. There are several threaded grooves 13 at the top of the annular plate 9, and all the sliders 10 and the annular grooves 11 are clearance-fitted, and threaded rods 12 are provided at the top of the annular plate 9 near all the sliders 10, and threaded grooves 13 matching the threaded rods 12 are provided at the top of the annular plate 9 and the tops of all the sliders 10. In the working process, the clearance fit ensures the flexible sliding of the slider 10 in the annular groove 11, and the fit between the threaded rod 12 and the threaded groove 13 can lock the slider 10 when needed to fix the position of the carrier plate 8, thereby achieving the effect of both ensuring the flexibility of the rotation of the carrier plate 8 and fixing its position when necessary, thereby further enhancing the stability and reliability of the bracket.

[0030] In summary:

[0031] First, when the orientation of the photovoltaic panel 7 needs to be adjusted according to the wind direction, the drive motor 4 fixedly connected to one side of the bottom of the base 1 by bolts is started. After the drive motor 4 is running, its output shaft drives the rotating rod 5 connected to it to rotate. The top of the rotating rod 5 is fixedly connected to the bottom of the bearing plate 8, so as the rotating rod 5 rotates, the bearing plate 8 will slide and rotate on the inner side of the annular plate 9. In this process, a number of sliders 10 fixedly connected to the side wall of the bearing plate 8 slide along the annular groove 11 opened on the annular plate 9, which plays a guiding and supporting role, ensuring the stability of the rotation of the bearing plate 8 and reducing friction loss. As the bearing plate 8 rotates, the orientation of the photovoltaic panel 7 fixedly connected to its top is also adjusted accordingly, realizing the flexible adjustment of the photovoltaic panel 7 according to the wind direction, effectively reducing wind resistance. At the same time, in order to enhance the stability of the photovoltaic bracket, plug plates 2 are provided on both sides of the bottom of the base 1, and fixed connection is achieved through the connecting plate 3 to form a stable support structure. When facing extreme wind conditions, the hydraulic cylinder 6 fixedly connected to the two sides of the bottom of the base 1 by bolts is controlled to extend its output shaft upward, further shortening the distance between the connecting plate 3 and the base 1. Since the connection between the output shafts of the two hydraulic cylinders 6 and the base 1 is a sliding connection, the distance between the connecting plate 3 can be adjusted more flexibly, which enhances the wind pressure resistance of the bracket and ensures the stability of the photovoltaic panel 7 and the bracket structure. The two plug plates 2 are symmetrically distributed along the center of the base 1. This symmetrical distribution design enables the bracket to disperse the pressure more evenly when subjected to force, further improving the overall structural stability and wind resistance of the bracket. In addition, the photovoltaic panel 7 is inclined, and its bottom end is located on the inner side of the annular plate 9. This inclined distribution is not only conducive to the photovoltaic panel 7 to better receive sunlight and improve the power generation efficiency, but also can reduce the direct impact of wind on the photovoltaic panel 7 when the wind conditions change, further reducing the wind resistance. In terms of detailed design, all the sliders 10 and the annular groove 11 are clearance-matched, ensuring the flexible sliding of the slider 10 in the annular groove 11. A threaded rod 12 is provided at the top of the annular plate 9 near all the sliders 10, and a threaded groove 13 matching the threaded rod 12 is provided at the top of the annular plate 9 and the top of all the sliders 10. When necessary, the slider 10 can be tightly fitted with the annular groove 11 by tightening the threaded rod 12, thereby locking the slider 10 and fixing the position of the carrier plate 8. This design not only ensures the flexibility of the rotation of the carrier plate 8, but also can fix its position when necessary, further enhancing the stability and reliability of the bracket. Through the cooperation of the drive motor 4, the rotating rod 5, the carrier plate 8, the slider 10 and the annular groove 11, the photovoltaic panel 7 can be flexibly adjusted according to the wind direction, effectively reducing the wind resistance and improving the power generation efficiency of the photovoltaic panel 7. At the same time, the wind resistance and overall structural stability of the bracket are enhanced by the design of the plug plate 2, the connecting plate 3, the hydraulic cylinder 6 and the symmetrical distribution. The inclined distribution of the photovoltaic panel 7 further improves the power generation efficiency and reduces the wind resistance.The clearance fit between the slider 10 and the annular groove 11 and the design of the threaded rod 12 and the threaded groove 13 ensure the flexibility of the rotation of the bearing plate 8 and can fix its position when necessary, further enhancing the stability and reliability of the bracket. In summary, the wind-resistant photovoltaic bracket has significant technical advantages and practical application value.
