[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figures 1-4 As shown, it includes a fixed base plate 1, a support frame 5 mounted on the fixed base plate 1 via a bearing 2, a limiting structure on the inner side of the bearing 2, a rotating structure below the support frame 5, an mounting frame 10 rotatably mounted on the support frame 5, a photovoltaic panel 11 mounted on the mounting frame 10, angle adjustment structures on both sides of the bottom of the mounting frame 10, a controller 14 inside the mounting frame 10, and anemometers 13 on both sides of the support frame 5.

[0023] See Figures 1-3 As shown, the angle adjustment structure includes a sliding groove 16 set on the support frame 5. A slider 19 is slidably installed in the sliding groove 16. A threaded rod 18 is rotatably installed in the sliding groove 16. A threaded groove is opened in the slider 19. The slider 19 is threadedly connected to the threaded rod 18. An adjustment motor 17 is provided at one end of the sliding groove 16. The rotating shaft of the adjustment motor 17 is connected to the threaded rod 18. An adjustment support rod 15 is connected to the upper end of the slider 19. The top end of the adjustment support rod 15 is connected to the mounting frame 10, and both the upper and lower ends of the adjustment support rod 15 are rotatably connected.

[0024] As an optimized solution of this utility model, by adjusting the motor 17 to drive the threaded rod 18 to rotate, the slider 19 can be moved through the thread, thereby moving the bottom end of the adjusting support rod 15, causing the mounting bracket 10 to rotate along the bottom rotating shaft, and adjusting the elevation angle of the photovoltaic panel 11.

[0025] See Figures 1-5 As shown, detection plates 12 are connected to both sides of the mounting bracket 10. Photoresistors are provided on the detection plates 12. The photoresistors and the anemometer 13 are both connected to the controller 14. The controller 14 is electrically connected to the rotary motor 8 and the regulating motor 17.

[0026] The rotating structure includes an annular connecting toothed ring 6 connected to the support frame 5 below. The connecting toothed ring 6 is an external toothed ring. The bottom side of the connecting toothed ring 6 is connected to the bearing 2. A rotary motor 8 is installed on the fixed base plate 1. The rotating shaft of the rotary motor 8 is connected to a drive gear 9. The drive gear 9 meshes with the connecting toothed ring 6.

[0027] The limiting structure includes a connecting ring 3 installed on the fixed base plate 1. The connecting ring 3 is located inside the bearing 2. A retaining ring 4 is installed above the connecting ring 3. The outer end of the retaining ring 4 is located on the bearing 2. Several sliding wheels 7 are provided along the edge of the bottom outer end of the retaining ring 4. The sliding wheels 7 are slidably positioned above the bearing 2.

[0028] As an optimized solution of this utility model, the controller 14 obtains the light intensity received by both sides of the photovoltaic panel 11 through the photoresistors in the two detection plates 12. When the resistance values ​​on both sides are different, it indicates that the photovoltaic panel 11 is not facing the sun. For example, if the resistance value of the left photoresistor is small and the resistance value of the right photoresistor is large, it indicates that the sunlight intensity on the left is high and the sun is located to the left of the position where the photovoltaic panel 11 is facing. At this time, the rotary motor 8 is started, and the drive gear 9 is connected to the gear ring 6 to drive the drive support frame 5, the mounting frame 10, and the photovoltaic panel 11 to rotate to the left until the resistance difference between the two photoresistors reaches within the threshold, which indicates that the photovoltaic panel 11 is facing the sun and realizes automatic rotation.

[0029] The controller 14 can obtain real-time wind speed information from both sides through the anemometer 13. When the wind speed is found to be too high, the controller can control the regulating motor 17 to lower the photovoltaic panel 11 to a near-flat position, thereby reducing the impact of wind on the photovoltaic panel 11 and preventing damage caused by excessive wind.

[0030] By setting a limiting structure, the connecting ring 3 and the retaining ring 4 can be used to lock the bearing 2 above the bearing 2, thereby limiting and protecting the bearing 2. This reduces the pulling force generated by the wind on the photovoltaic panel 11 and the bearing 2. The sliding wheel 7 can rotate to prevent friction between the retaining ring 4 and the bearing 2.

[0031] The usage process of this utility model:

[0032] First, install the fixed base plate 1, then install the retaining ring 4 onto the connecting ring 3, and then connect the connecting toothed ring 6 to the bearing 2. Next, install the photovoltaic panel 11 onto the mounting frame 10, and then install and wire the remaining structure to complete the installation.

[0033] During use, the photoresistor in the detection board 12 tracks the position of the sun and automatically drives the photovoltaic panel 11 to rotate, keeping the photovoltaic panel 11 facing the sun and ensuring power generation efficiency. At the same time, the angle adjustment structure can adjust the vertical angle of the photovoltaic panel 11, and then adjust the elevation angle of the photovoltaic panel 11 according to the seasonal solar altitude angle to further ensure power generation efficiency. Meanwhile, the anemometer 13 monitors the wind force, and if necessary, lowers the photovoltaic panel 11 to reduce the impact of wind on the photovoltaic panel 11.

[0034] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
