Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-5 A photovoltaic energy storage device resistant to wind and sand erosion includes a light pole 1 and a base 2 integrating a battery and circuit equipment. The base 2 is fixedly installed on the top of the light pole 1, and a flip-out shielding component is provided on the top of the base 2.

[0026] The flip-out shading assembly includes a mounting platform 3, with a drive frame 4 and a flip frame 5 on both sides of the mounting platform 3. A movable plate 6 is provided between the drive frame 4 and the flip frame 5, and a photovoltaic panel 7 is fixedly installed inside the movable plate 6.

[0027] Furthermore, multiple support rods 8 are fixedly connected between the base 2 and the mounting platform 3 to increase the structural strength of the base 2 and the mounting platform 3 and prevent the mounting platform 3 from being overturned by strong winds during sandstorms.

[0028] Furthermore, the center of the mounting platform 3 is provided with a heat dissipation hole 9 that matches the base 2. The heat dissipation hole 9 connects the mounting platform 3 and the base 2. A brush strip 10 for cleaning the photovoltaic panel 7 is fixedly connected to the surface of the edge of the mounting platform 3.

[0029] The further advantage of adopting the above is that during the shading action of the flip-to-shade component, the surface of the photovoltaic panel 7 can be cleaned by the brush strip 10, thereby removing the sand and dust that adheres to the photovoltaic panel 7 during the day. When the flip-to-shade component is in the shading state, the heat dissipation hole 9 is covered by the movable plate 6, preventing sand and dust carried by the sandstorm from entering the heat dissipation hole 9.

[0030] Furthermore, a lead screw 11 is rotatably connected inside the drive frame 4. The input end of the lead screw 11 passes through the drive frame 4 and is connected to a drive motor 12. The body of the lead screw 11 is threadedly connected to a drive slider 13. The upper and lower surfaces of the drive slider 13 are slidably connected to the inner wall of the drive frame 4. A flip slider 14 matching the drive slider 13 is slidably connected inside the flip frame 5. A flip motor 15 is fixedly installed on the side of the flip slider 14 away from the drive slider 13. One side of the movable plate 6 is rotatably connected to the drive slider 13. The other side of the movable plate 6 passes through the flip slider 14 and is connected to the flip motor 15. A rectangular protective pad 16 is fixedly connected to the surface of the movable plate 6. The movable plate 6 is electrically connected to the base 2.

[0031] A further advantage of the above is that the rotating motor 15 drives the movable plate 6 to rotate, so that the photovoltaic panel 7 faces the surface of the mounting platform 3. Then, the rotation of the lead screw 11 drives the drive slider 13 to slide, and the drive slider 13 drives the rotating slider 14 and the movable plate 6 to slide to... Figure 3 As shown, by sealing the edge of the photovoltaic panel 7 with the rectangular protective pad 16, the photovoltaic panel 7 is shielded and the heat dissipation holes 9 are sealed at night and in sandstorm environments, thus solving the protection problem of photovoltaic energy storage devices in sandstorm environments.

[0032] When this utility model is working during the daytime, the flip-out shielding component is... Figure 1 As shown, the angle of the photovoltaic panel 7 is maintained by the self-locking property of the flip motor 15;

[0033] When working at night or in sandstorm conditions, the movable plate 6 is first rotated by the flip motor 15. Figure 2 The photovoltaic panel 7 is positioned so that it faces the surface of the mounting platform 3. Then, the drive motor 12 drives the lead screw 11 to rotate. The rotation of the lead screw 11 causes the drive slider 13 to slide, which in turn causes the flip slider 14 and the movable plate 6 to slide to... Figure 3 The state shown is to complete the shading. During this process, the surface of the photovoltaic panel 7 is cleaned by the brush strip 10 to remove the sand and dust that adheres to the photovoltaic panel 7 during the day. After the shading is completed, the edge of the photovoltaic panel 7 is sealed by the rectangular pad 16. When the movable plate 6 is in the shading state, it can also cover the heat dissipation hole 9 to prevent the sand and dust carried by the sandstorm from entering the heat dissipation hole 9, thus achieving the function of shading the photovoltaic panel 7 at night and in the sandstorm environment.

[0034] When used in normal environments, the flip-to-shade component operates on a timed schedule according to the day and night length of the area, switching to a shading state at night. Before a sandstorm occurs, staff need to operate the terminal of the control center in advance according to the weather forecast so that the flip-to-shade component can complete the shading action before the sandstorm arrives. The movable plate 6 provides double protection, both shading the photovoltaic panel 7 and sealing the heat dissipation holes 9, thus solving the protection problem of photovoltaic energy storage devices in sandstorm environments.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
