[0052] Detailed usage and function of this embodiment:

[0053] When the motor 8 is started, the motor 8 drives the fixed column 9 to rotate. After the fixed column 9 rotates, the arc frame 10 connected to one side will flip left and right together. The arc frame 10 drives the column 11. After the column 11 rotates, the shaft 12 inserted on one side of the column 11 will flip left and right together. The shaft 12 drives the circular ring 13 to flip left and right.

[0054] When the motor 15 is started, it drives the gear 16 to rotate. The gear 16 drives the meshing gear 17 to rotate. After the gear 17 rotates, it drives the shaft 12 that is inserted in the middle, causing the shaft 12 to drive the circular ring 13 to flip back and forth.

[0055] When the second motor 19 is started, it drives the first gear 20 to rotate. The first gear 20 rolls on the tooth groove of the side gear 21. The first guide slider 26 and the second guide slider 28 slide in the corresponding arc-shaped guide rail 14. The first guide slider 26 and the second guide slider 28 drive the fixed block 22 and the disc 18 to slide along the periphery of the circular ring 13. The arc-shaped frame 25 drives the solar photovoltaic panel 7 to move.

[0056] The mounting bracket 6 presses down on the horizontal strip 32. Under the elastic action of the return spring 35, the limiting wheel 37 is always pressed against the inverted V groove of the two wing plates 39. Under the action of the gravity of the gravity blocks 45 on both sides, a downward gravity is generated, which reduces the amplitude of the angular rotation of the rotating arm 42 and improves the balance of the horizontal strip 32.

[0057] Through the specific embodiments described above, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
