Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panels, and in particular to an anti-wind damping mechanism of a photovoltaic panel. Background Art

[0002] Photovoltaic panels, devices that directly convert solar energy into electricity, are widely used in the renewable energy sector, boasting the advantages of being clean, environmentally friendly, and sustainable. With the rapid development of photovoltaic power generation technology, PV panels are increasingly being used in building-integrated systems, ground-based power stations, and in complex terrain environments. As core components of photovoltaic power generation systems, their installation stability and operational safety have a decisive impact on the overall system's power generation efficiency and service life.

[0003] Especially in outdoor installations, where photovoltaic panels and their supporting structures are exposed to the elements for extended periods, particularly during strong winds, existing photovoltaic panel mounting structures are significantly deficient in wind resistance. As a key protection measure, the commonly used fixed brackets or simple buffer structures lack effective wind damping mechanisms when subjected to strong winds, resulting in violent shaking and resonance between the photovoltaic panel and bracket.

[0004] Specifically, the photovoltaic panels in the prior art lack effective wind damping effects when in use, so that the shaking of the photovoltaic panels and photovoltaic brackets in windy weather cannot be effectively suppressed. This vibration will not only cause uneven force on the edges of the photovoltaic panels, resulting in damage to the frame or glass, but may also cause the connectors to loosen or even fall off, seriously affecting the normal operation of the photovoltaic system. In addition, due to the lack of dynamic response capabilities, traditional structures are difficult to adapt to the changing working conditions under different wind speed levels, and cannot achieve automatic adjustment and energy dissipation. What is more serious is that these problems not only significantly increase maintenance costs and failure rates, but may also bring potential risks to the overall safety and power generation efficiency of the photovoltaic system, especially in coastal areas, plateaus and other areas with abundant wind resources but frequent wind disasters. This problem is particularly prominent. Therefore, in view of the many shortcomings in the existing technology, there is an urgent need for an innovative photovoltaic panel wind damping mechanism to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an anti-wind damping mechanism for a photovoltaic panel, which solves the problem that the photovoltaic panels in the prior art lack effective anti-wind damping effect when in use, so that the shaking of the photovoltaic panels and photovoltaic brackets in windy weather cannot be effectively suppressed. This vibration will not only cause uneven force on the edges of the photovoltaic panels, resulting in damage to the frame or glass, but may also cause the connectors to loosen or even fall off, seriously affecting the normal operation of the photovoltaic system.

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

[0007] The top of the frame is fixedly provided with a top plate, and both sides of the bottom of the top plate are slidably connected to the connecting plates, and the bottoms of the two connecting plates are fixedly connected to the top of the frame, the top of the top plate is fixedly connected to the photovoltaic panel, and the bottom of the top plate is fixedly connected to the fixing plate, and both sides of the fixing plate are fixedly connected to a group of support rods, wherein each group of support rods is provided with two, one end of the four support rods respectively passes through the two connecting plates, and one end of the support rod is elastically connected to one side of the connecting plate, the bottom of the fixing plate is rotatably connected to a swing block by a pin shaft, and both sides of the top plate are fixedly connected to a reinforcing plate, and one side of the two reinforcing plates is slidably connected to a support plate, wherein the bottoms of the two support plates are fixedly connected to side plates, the bottoms of the two side plates are slidably connected to the inner bottom of the frame, and one side of the two side plates is fixedly connected to a water tank, and a valve body is installed on the lower side of the water tank.

[0008] Preferably, a plurality of bottom rods are fixedly connected to the bottom of the two side panels, and all the bottom rods are slidably connected to the inner bottom of the frame through the bottom groove.

[0009] Preferably, the tops of the two connecting plates are fixedly connected with sliding blocks, and the two sliding blocks are slidably connected to the bottom of the top plate through sliding grooves.

[0010] Preferably, a plurality of ventilation holes are provided on both connecting plates, a plurality of ventilation slots are provided on both sides of the frame, and a top slot is provided on the top plate.

[0011] Preferably, the four support rods are each provided with an extrusion spring, and one end of the four support rods is elastically connected to one side of the connecting plate through the extrusion spring, and one side of the fixed plate is fixedly connected to one side of the two connecting plates through a damper.

[0012] Preferably, one side of each of the two support plates is fixedly connected with a slider, and both sliders are slidably connected to one side of the top plate through a sliding groove.

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

[0014] The elastic connection between the support rods and the connecting plate effectively alleviates the inability of traditional fixed supports to withstand sudden windstorms. This design provides initial cushioning protection for the photovoltaic panels during strong winds, preventing frame deformation or glass breakage caused by sudden impacts and improving the system's mechanical stability. Secondly, the swing block is connected to the fixed plate via a pin, allowing it to swing relative to the roof panel when it sways. This leverages its mass inertia to provide secondary dynamic damping, compensating for the lack of adaptive adjustment capabilities found in traditional structures and improving the system's responsiveness to variable wind conditions. Thirdly, the presence of water in the water tank provides additional inertial mass, generating a counterforce during wind vibration, further dampening the sway of the photovoltaic panels and roof panel, extending the equipment's service life and reducing maintenance frequency. This design demonstrates enhanced suitability in high-wind conditions, such as coastal areas and plateaus. Furthermore, the sliding connection between the support plate and reinforcement plate, as well as the sliding fit between the side panels and the frame, not only enhances the overall structural rigidity but also allows for a limited range of free deformation, avoiding stress concentrations caused by excessive rigidity constraints and reducing the risk of loosening or even detachment of the connectors.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to 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.

[0024] Example 1

[0025] Reference Figure 1-6 , including a frame 1, a top plate 5 is provided on the top of the frame 1, and both sides of the bottom of the top plate 5 are slidably connected to the connecting plates 2, and the bottoms of the two connecting plates 2 are fixedly connected to the top of the frame 1, the top of the top plate 5 is fixedly connected to the photovoltaic panel 13, and the bottom of the top plate 5 is fixedly connected to the fixing plate 21, and both sides of the fixing plate 21 are fixedly connected to a group of support rods 17, wherein each group of support rods 17 is provided with two, and one end of the four support rods 17 is respectively connected to the two connecting plates 2, and one end of the support rod 17 is fixed to the top of the top plate 5. It is elastically connected to one side of the connecting plate 2, and the bottom of the fixed plate 21 is rotatably connected to the swing block 20 through a pin shaft, and both sides of the top plate 5 are fixedly connected to the reinforcing plates 6, and one side of the two reinforcing plates 6 is slidably connected to the support plates 9, wherein the bottoms of the two support plates 9 are fixedly connected to the side plates 10, and the bottoms of the two side plates 10 are slidably connected to the inner bottom of the frame 1, and one side of the two side plates 10 is fixedly connected to the water tank 11, and a valve body 12 is installed on the lower side of the water tank 11.

[0026] First, the photovoltaic panel 13 is installed on the top of the top plate 5 and supported as a whole by the frame 1. During normal use, the photovoltaic panel 13 receives sunlight and completes the photoelectric conversion process, and the system is in a stable operating state. When encountering strong winds, the wind acts on the photovoltaic panel 13 and the surface of the top plate 5, causing them to shake or vibrate. At this time, the anti-wind damping mechanism begins to work: first, the shaking of the top plate 5 will cause the reinforcing plate 6 fixed to it to move, and at the same time, the connecting plates 2 on both sides of the bottom of the top plate 5 also move accordingly. Since the connecting plate 2 and the top plate 5 are connected in a sliding manner, and one end of the support rod 17 is connected to the connecting plate 2 by an elastic structure, the elastic connection between the support rod 17 and the connecting plate 2 can absorb part of the initial vibration energy, playing a preliminary buffering and shock-absorbing role. At the same time, the fixed plate 21 moves with the top plate 5, and the swing block 20 at its bottom, which is connected by a pin shaft, swings relative to each other under the action of inertia, further consuming vibration energy and achieving a dynamic damping effect. Furthermore, support plates 9 are slidably connected to one side of each of the two reinforcing plates 6. The bottom of the support plates 9 forms a sliding fit with the inner bottom of the frame 1 via the side plates 10, thereby enhancing the overall stability of the structure. A water tank 11 fixed to the side plates 10 contains a certain amount of water. During sloshing, the water generates a reverse force due to inertia, exerting additional inertial damping on the entire structure, further enhancing the system's wind resistance. A valve 12, located on one side of the lower portion of the water tank 11, can be used to adjust the water volume to accommodate usage requirements at different wind speed levels, enhancing the device's applicability and flexibility.

[0027] Example 2

[0028] Reference Figure 1-6 The bottoms of the two side panels 10 are fixedly connected with a plurality of bottom rods 22 , and all the bottom rods 22 are slidably connected to the inner bottom of the frame 1 through the bottom grooves 23 .

[0029] The arrangement of several bottom bars 22 fixedly connected to the bottom of the side panels 10 and the bottom grooves 23 formed in the inner bottom of the frame 1 allows the side panels 10 to slide more smoothly along the bottom grooves 23. This design enhances the horizontal mobility and stability of the entire structure, especially in strong winds. It can more effectively disperse stress and reduce the risk of damage caused by rigid constraints, thereby further improving the overall stability and durability of the device.

[0030] Example 3

[0031] Reference Figure 1-6 The tops of the two connecting plates 2 are fixedly connected with sliding blocks 15, and the two sliding blocks 15 are slidably connected to the bottom of the top plate 5 through the sliding grooves 16.

[0032] The sliding blocks 15 fixedly connected at the tops of the two connecting plates 2 and the sliding slots 16 provided at the bottom of the top plate 5 allow the connecting plates 2 to move smoothly along the bottom of the top plate 5. This sliding mechanism not only ensures the effective elastic connection between the support rods 17 and the connecting plates 2, but also provides additional adjustment space to accommodate varying degrees of vibration or displacement, increasing the system's adaptability to environmental changes and helping to extend the equipment's service life.

[0033] Example 4

[0034] Reference Figure 1-6 , a plurality of ventilation holes 3 are provided on the two connecting plates 2 , a plurality of ventilation slots 4 are provided on both sides of the frame 1 , and a top slot 14 is provided on the top plate 5 .

[0035] The ventilation holes 3 on the connecting plate 2, the ventilation slots 4 on both sides of the frame 1, and the top groove 14 on the top plate 5 form an effective air circulation path. This design helps to reduce the temperature below the photovoltaic panels 13, reducing efficiency losses caused by hot spots, and helps to alleviate the direct impact of strong winds on the device. By guiding airflow, it reduces resistance, thereby improving the system's power generation efficiency and wind resistance.

[0036] Example 5

[0037] Reference Figure 1-6 The four support rods 17 are each provided with an extrusion spring 18, and one end of the four support rods 17 is elastically connected to one side of the connecting plate 2 through the extrusion spring 18, and one side of the fixing plate 21 is fixedly connected to one side of the two connecting plates 2 through the damper 19.

[0038] By configuring the compression springs 18 mounted on the four support rods 17 and the damper 19 secured between one side of the fixing plate 21 and the connecting plate 2, when the photovoltaic panel 13 is impacted by external forces, the compression springs 18 effectively absorb and mitigate initial vibrations, while the damper 19 further dissipates any remaining energy, preventing excessive rebound or sustained vibration. This not only protects the photovoltaic panel 13 from mechanical damage but also ensures its long-term stable operation, reducing maintenance costs and improving reliability.

[0039] Example 6

[0040] Reference Figure 1-6 One side of the two support plates 9 is fixedly connected with a slider 7, and the two sliders 7 are slidably connected to one side of the top plate 5 through the slide groove 8.

[0041] The design of the sliders 7 fixedly connected to one side of the two support plates 9 and the chute 8 provided on the side of the top plate 5 allows the support plates 9 to slide smoothly within the chute 8. This not only strengthens the connection between the top plate 5 and the support plates 9, but also provides additional support points for the entire structure, enhancing its stability in the face of lateral forces. Furthermore, this design helps to distribute the pressure applied to various components, reducing the occurrence of localized stress concentration and improving the overall reliability and durability of the system.

[0042] In summary:

[0043] The overall structure includes a frame 1, a top plate 5 fixedly mounted on the top of the frame 1, and connecting plates 2 slidingly connected to the bottom of the frame 1 on both sides. The bottoms of the two connecting plates 2 are fixedly connected to the top of the frame 1, forming a stable support base. A photovoltaic panel 13 is fixedly installed on the top of the top plate 5 to perform photoelectric conversion under normal lighting conditions, and a fixed plate 21 is fixedly connected to the bottom of the top plate 5. A group of support rods 17 are fixedly connected to each side of the fixed plate 21. One end of the four support rods 17 passes through the two connecting plates 2 respectively and is elastically connected to one side of the connecting plate 2 through an extrusion spring 18, forming a primary buffer and shock absorption system. At the same time, the bottom of the fixed plate 21 is connected to the swing block 20 through a pin shaft. When the top plate 5 shakes, the swing block 20 is driven to swing inertially, realizing a dynamic damping function. The top plate 5 is fixedly connected to the two sides of the reinforcing plate 6. One side of the two reinforcing plates 6 is slidably connected to the support plate 9. The bottom of the support plate 9 slides with the bottom of the inner side of the frame 1 through the side plate 10, enhancing the lateral stability of the entire device. A water tank 11 is fixedly provided on the side panel 10, which contains a certain amount of water. Under the action of strong winds, a reverse force is generated due to inertia, providing additional inertial damping effect. A valve body 12 is provided on one side of the lower part of the water tank 11 to adjust the water volume to adapt to different wind speed conditions and improve environmental adaptability. Several bottom rods 22 are fixedly connected to the bottom of the side panel 10. All bottom rods 22 are slidably connected to the bottom of the inner side of the frame 1 through the bottom groove 23, so that the side panel 10 slides smoothly along the bottom groove 23, thereby enhancing the flexibility and stability of horizontal movement, reducing the stress concentration problem under the action of strong winds, and improving overall durability. A sliding block 15 is provided on the top of the connecting plate 2, which slides with the sliding groove 16 opened at the bottom of the top plate 5, so that the connecting plate 2 can slide flexibly under the top plate 5, which not only ensures the effectiveness of the elastic connection between the support rod 17 and the connecting plate 2, but also improves the adaptability to different vibration amplitudes and extends the service life. The connecting plate 2 is provided with ventilation holes 3, the frame 1 is provided with ventilation slots 4 on both sides, and the top plate 5 is provided with a top slot 14, forming a complete air circulation path, effectively reducing the temperature below the photovoltaic panel 13 and reducing the impact of the hot spot effect. At the same time, it guides the airflow to reduce the impact of wind pressure, thereby improving power generation efficiency and wind resistance. The support rod 17 is provided with an extrusion spring 18, which is elastically connected to the connecting plate 2. One side of the fixed plate 21 is fixedly connected to the connecting plate 2 through a damper 19. When subjected to external force impact, the extrusion spring 18 absorbs the initial vibration energy, and the damper 19 further consumes the remaining energy to prevent excessive rebound or continuous vibration, significantly improving the stability and reliability of the system and reducing maintenance frequency. A slider 7 is provided on one side of the support plate 9, which slides with the slide 8 provided on one side of the top plate 5, allowing the support plate 9 to slide smoothly in the slide 8. This not only enhances the support strength, but also provides additional support points, enhancing stability in the face of lateral wind force, while dispersing the force, avoiding local stress concentration, and improving overall durability and safety.The elastic buffer structure composed of the support rod 17 and the extrusion spring 18, the dynamic inertial damping of the swing block 20, the liquid center of gravity offset damping of the water tank 11 and the auxiliary stabilization mechanism of the sliding structure form a comprehensive wind-resistant system from static to dynamic, from mechanical to fluid. It can effectively alleviate the problems of traditional photovoltaic brackets that are prone to shaking, resonance, frame damage, loosening and falling off of connectors in windy weather, significantly improve the operating stability and safety of the photovoltaic system, extend the service life of the equipment, and meet the needs of efficient power generation in complex natural environments.
