However, how to effectively utilize solar energy resources in a sandy environment and improve the power generation efficiency and stability of solar panels has always been a technical problem faced by the industry. The sandy activities in desert areas are frequent, posing a serious threat to the solar panels of traditional solar panel power generation devices. The long-term impact of sand and wind on the surface of solar panels will cause wear of the panel materials, which not only affects the appearance of solar panels, but may also reduce their service life and performance, affect their power generation efficiency, and shorten their service life. Therefore, developing a solar panel that can resist sand and wind erosion is of great significance for achieving stable power generation in harsh environments such as deserts. Content of the Utility Model

[0017] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] As Figures 1-6 shown. A solar panel power generation device including a wind shielding structure comprises a solar panel 5, the solar panel 5 is arranged on a base 1, a sand flux sensor 4 is fixed on one side of the top of the base 1, one end of the base 1 is provided with a wind shielding structure, the wind shielding structure includes a wind shield 15, the wind shield 15 is hinged to the base 1, and the wind shield 15 is connected with an angle adjusting mechanism capable of driving it to rotate.

[0019] During use, a support column 2 is arranged on the base 1, the solar panel 5 is fixed by the support column 2, the model of the sand flux sensor 4 is SandFlowSF4, and its working principle is to use a sensor that is sealed and has low power consumption and no other moving parts to determine the intensity and speed of the flying sand flow based on the internal sound pressure changes caused by the impact of the sand flow and the friction of the wind laminar flow. The sand flux sensor 4 is used to detect the intensity of the wind and sand. When the wind and sand intensity exceeds a preset value, the angle position of the wind shield 15 is adjusted by the angle adjusting mechanism to block the wind and sand from blowing onto the surface of the solar panel 5. When adjusting the angle position of the wind shield 15, an adaptive adjustment can be made according to the wind and sand intensity. On the premise that the wind shield 15 can ensure blocking the wind and sand, it is necessary to ensure that sunlight can shine on the solar panel as much as possible.

[0020] The angle adjusting mechanism includes a second motor 18, a worm 19 and a worm wheel 20. A concave block 13 is fixed on one side of the base 1, a rotating rod 16 is rotatably connected to the concave block 13, connecting blocks 17 are fixed on the top and bottom of one side of the concave block 13, a worm 19 is rotatably connected between the two connecting blocks 17, a second motor 18 is fixed on the top of one of the connecting blocks 17, the output end of the second motor 18 is fixed to the worm 19, a worm wheel 20 is fixed on the rotating rod 16, the worm wheel 20 is meshed with the worm 19, and the rotating rod 16 is fixedly connected to the wind shield 15 through a connecting rod 14. The angle of the wind shield 15 is adjusted by controlling the forward and reverse rotation of the second motor 18. When there is no wind and sand or the wind and sand intensity is lower than the preset value, the wind shield 15 is adjusted to rotate away from the solar panel 5 so that the solar panel 5 can receive sufficient sunlight.

[0021] A cleaning structure is provided at the top of the solar panel 5. The cleaning structure includes a first motor 7, a first screw rod 8, a second screw rod 10 and a cleaning brush 12. Mounting blocks 6 are fixed on both sides of the solar panel 5. A sliding rod 11 is fixed between the two mounting blocks 6. A first motor 7 is fixed on one side of the mounting block 6. The output end of the first motor 7 is fixed with a first screw rod 8. One end of the first screw rod 8 is fixed with a connecting rod 9. The end of the connecting rod 9 is fixed with a second screw rod 10. The thread rotation directions of the first screw rod 8 and the second screw rod 10 are opposite. Cleaning brushes 12 are threadedly connected to both the first screw rod 8 and the second screw rod 10. Both of the two cleaning brushes 12 are slidably connected to the sliding rod 11, and the cleaning brushes 12 are in contact with the solar panel 5. By driving the first screw rod 8 and the second screw rod 10 to rotate through the forward and reverse rotation of the first motor 7, the two cleaning brushes 12 can move away from or close to each other, so as to clean the sand on the surface of the solar panel. The cleaning brush is made of a soft material to avoid scratching the solar panel.

[0022] The sand flux sensor 4, the first motor 7 and the second motor 18 are all connected to the controller 3.

[0023] When the whole utility model works, the sand and dust flux sensor 4 can detect the intensity of sand and dust. After the sand and dust reaches a certain intensity, the sand and dust flux sensor 4 sends a signal to the controller 3, and the controller 3 sends a signal to the second motor 18. The output end of the second motor 18 drives the worm 19 to rotate. Since one side of the worm 19 is meshed and connected with the worm wheel 20, the rotation of the worm 19 drives the worm wheel 20 to rotate, and then drives the rotating rod 16 to rotate. The rotating rod 16 can drive the connecting rod 14 and the wind shield 15 to rotate accordingly, so that the wind shield 15 blocks the windward side of the solar panel, providing wind and sand protection for the solar panel 5, enabling the device to reduce the abrasion of the sand and dust on the surface of the solar panel 5, reducing the risk of surface wear and damage of the panel, and thus extending the service life of the solar panel 5. When dust accumulates on the surface of the solar panel 5, the controller 3 controls the first motor 7 to rotate electrically. The output end of the first motor 7 drives the first screw rod 8, the connecting rod 9 and the second screw rod 10 to rotate. Since the thread directions of the first screw rod 8 and the second screw rod 10 are opposite, and cleaning brushes 12 are threadedly connected to the outer sides of the first screw rod 8 and the second screw rod 10, the rotation of the first screw rod 8 and the second screw rod 10 drives the two cleaning brushes 12 to approach or move away from each other, so that the two cleaning brushes 12 can clean the surface of the solar panel 5, and thus reduce the accumulation of sand and dust on the surface of the solar panel 5. By cleaning the sand and dust on the surface of the solar panel 5 in time, the cleaning structure can significantly reduce the influence of sand and dust on the solar panel 5 receiving sunlight, improve the efficiency of converting light energy into electrical energy, and the clean solar panel 5 can absorb sunlight more fully, thereby increasing the power generation. In summary, the utility model can achieve the advantages of automatic cleaning, improving power generation efficiency, extending service life, reducing maintenance costs and enhancing system reliability, providing an effective solution for solar power generation in harsh sand and dust environments.

[0024] The above is only the preferred embodiment of the present utility model.
