Description

Technical Field

[0001] This utility model relates to the field of solar panel technology, specifically to a solar photovoltaic panel with a windproof fixing device. Background Technology

[0002] Solar photovoltaic (PV) panels are devices that convert solar energy into electrical energy. As a clean energy source, solar energy does not harm the environment or surrounding people, so its development has received strong government support in recent years. To improve the power generation efficiency of solar panels, they are generally installed at an angle to allow them to receive more sunlight. However, common solar PV panels are usually fixed structures that are difficult to adjust after installation. In strong winds, when tilted PV panels are blown by the wind, their larger windward area results in greater stress, making them more susceptible to damage or loosening of the mounting brackets. In some cases, the panels may even be blown off, posing a safety hazard. Utility Model Content

[0017] Reference Figures 1 to 4 As shown, this utility model provides a solar photovoltaic panel with a windproof fixing device, including: a fixing frame 1, an mounting plate 10 movably connected to the upper surface of the fixing frame 1 via bearings, a photovoltaic panel component 11 fixedly connected to the upper surface of the mounting plate 10, and an upper movable plate 14 movably connected to the middle of the lower surface of the mounting plate 10 via bearings. Wind speed sensors 8 are fixedly connected to both sides of the fixing frame 1 via extension plates 7. A guide rod 2 and a servo cylinder 9 are fixedly connected to the inner cavity of the fixing frame 1, and the telescopic rod of the servo cylinder 9 is fixedly connected to a moving plate 5. A guide hole is opened on the surface of the moving plate 5 relative to the position of the guide rod 2. A lower movable plate 6 is movably connected to the upper surface of the moving plate 5 via bearings, and an elastic element 12 and a damper 13 are fixedly connected between the lower movable plate 6 and the upper movable plate 14, respectively.

[0018] In this embodiment, after the solar photovoltaic panel is moved to a suitable position, ground nails or fixing bolts are sequentially embedded in the through holes opened on the surfaces of the fixed frame 1 and the extension plate 7, thereby completing the installation of the solar photovoltaic panel. When strong winds occur, the wind will cause the wind speed sensor 8 to rotate, and the wind speed sensor 8 will transmit the corresponding data to the electrically connected PLC component. When the wind speed data exceeds the preset upper limit of the PLC component, the PLC component will activate the electrically connected servo cylinder 9. The extension rod of the servo cylinder 9 will drive the moving plate 5 to move. The movement of the moving plate 5 will act on the mounting plate 10 through the lower movable plate 6, the elastic element 12 and the upper movable plate 14, so that the tilt angle of the mounting plate 10 and the photovoltaic panel 11 gradually decreases until it is easy to be horizontal, thereby effectively reducing the tilt angle of the photovoltaic panel 11. In strong winds, the impact of strong winds on the photovoltaic panel 11 is reduced, decreasing the likelihood of damage or falling off the photovoltaic panel 11 due to strong winds. It also helps reduce the overall wind-exposed area of ​​the solar photovoltaic panel, reducing the likelihood of loosening or falling off the fixing structure such as the fixing frame 1, ensuring the safety of the solar photovoltaic panel after installation. During the storage of the mounting plate 10 and the photovoltaic panel, if the force of the strong wind on the surface of the photovoltaic panel 11 is too great, the mounting plate 10 will squeeze the elastic element 12 through the upper movable plate 14, reducing the tilt angle of the mounting plate 10 and the photovoltaic panel 11 in advance, thereby helping to reduce the blowing effect of the strong wind and ensuring that the mounting plate 10 and the photovoltaic panel 11 can be stored smoothly. The setting of the counterweight plate 3 can further enhance the windproof and fixing effect of the device.

[0019] As a preferred embodiment, the fixing frame 1 has a U-shaped structure, and four sets of through holes are symmetrically opened at the four corners of the upper surface of the fixing frame 1. The two sets of extension plates 7 fixedly connected to the outer side of the fixing frame 1 are both square structures, and wiring grooves are opened inside the extension plates 7.

[0020] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The through holes allow the fixing frame 1 to be fixedly connected at designated locations using ground nails or fixing bolts, while the extension plate 7 helps to enhance the fixing effect.

[0021] In a preferred embodiment, the two sets of guide rods 2 fixedly connected to the inner cavity of the fixed frame 1 are both cylindrical in shape, and the two sets of guide rods 2 are symmetrically distributed on both sides of the servo electric cylinder 9. At the same time, the fixed frame 1 and the guide rods 2 are combined together to form a U-shaped structure.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The guide rod 2 helps to enhance the stability of the moving plate 5 during movement, ensuring that the moving plate 5 can move along a specific path inside the fixed frame 1.

[0023] In a preferred embodiment, the movable plate 5 has a rectangular structure, the guide holes at both ends of the movable plate 5 are adapted to the size of the corresponding guide rod 2, and the lower movable plate 6 connected to the upper surface of the movable plate 5 has a rectangular structure. At the same time, the guide rod 2 is fixedly connected to the end face of the counterweight plate 3 with a limiting ring 4 having a circular structure.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The guide hole and guide rod 2 are matched in size, which helps to enhance the stability of the moving plate 5 when it moves. The setting of the limiting ring 4 can limit the movement range of the counterweight plate 3 and the moving plate 5 respectively, ensuring that the mounting plate 10 can be unfolded and stored smoothly.

[0025] As a preferred embodiment, the counterweight plate 3 has a square structure, the size of the counterweight plate 3 and the inner cavity of the fixing frame 1 are adapted to each other, and the lower surface of the counterweight plate 3 is provided with a fitting groove corresponding to the position of the guide rod 2.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The addition of counterweight plate 3 effectively increases the overall weight of the bottom of the solar photovoltaic panel, thereby reducing the chance of the solar photovoltaic panel being blown away by strong winds and enhancing the windproof and fixing effect.

[0027] In a preferred embodiment, the upper movable plate 14 has a rectangular structure, and four sets of elastic elements 12 are symmetrically connected between the upper movable plate 14 and the lower movable plate 6, and the four sets of elastic elements 12 are symmetrically distributed on both sides of the damper 13.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The stiffness coefficient of the elastic element 12 can be selected according to actual needs, so that the total weight of the mounting plate 10 and the photovoltaic panel 11 can prevent the elastic element 12 from being compressed, ensuring that the solar photovoltaic panel can be smoothly unfolded and stored, and helping to enhance the windproof effect. At the same time, both ends of the damper 13 are movably connected to the upper movable plate 14 and the lower movable plate 6 respectively through bearings.

[0029] In a preferred embodiment, the mounting plate 10 has a rectangular structure, the size of the mounting plate 10 is larger than the size of the inner cavity opening of the fixing frame 1, and the mounting plate 10 forms a V-shaped structure with the fixing frame 1 after being unfolded. At the same time, a through hole is opened on the side of the extension plate 7 away from the fixing frame 1.

[0030] In this embodiment, as Figure 1 and Figure 2 The mounting plate 10 allows the photovoltaic panel 11 to be easily installed, removed, and its tilt angle adjusted, thereby enhancing the windproof and fixing effect of the solar photovoltaic panel.
