[0031] The side wall of one of the first stands 9 is fixedly connected with a horizontal plate 24, and the upper surface of the horizontal plate 24 is fixedly connected with a wind speed sensor 25.

[0032] Specifically, the controller can be connected between the electric push rod 17 and the wind speed sensor 25. When the wind speed sensor 25 detects that the wind speed exceeds the set threshold, it transmits this information to the controller, and the controller controls the electric push rod 17 to start. The controller and its control principle are common existing technologies, and will not be repeated here.

[0037] When the wind speed is small, the photovoltaic panel 2 does not need to be in a horizontal state in order to improve the use efficiency of the photovoltaic panel 2. The wind blows the photovoltaic panel 2 and drives the bottom plate 18 to slide in the bottom box 1, and the second springs 21 are elastically deformed and buffer and absorb shocks.

[0038] Working principle: When the photovoltaic panel 2 is blown by the wind, the slide rod 4 slides downward in the cylinder 5, and when the slide rod 4 slides in the cylinder 5, the first springs 8 are compressed and buffer and absorb shocks for the first time, and at the same time, the slide rod 4 extrudes the silicon oil in the cylinder 5 into the liquid storage sleeve 6 through the round holes 7, and the liquid storage sleeve 6 expands and becomes larger to buffer and absorb shocks for the second time, so as to protect the photovoltaic panel 2 and the photovoltaic support from being damaged.

[0039] A controller can be arranged to be connected between the electric push rod 17 and the wind speed sensor 25, and when the wind speed sensor 25 detects that the wind speed exceeds a set threshold value, the information is transmitted to the controller, and the controller controls the electric push rod 17 to start. Specifically, when the wind speed sensor 25 detects that the wind speed exceeds a set threshold value, the information is transmitted to the controller, and the controller controls the electric push rod 17 to start, and the telescopic end of the electric push rod 17 is retracted, and then drives the support plate 3 to turn downward around the first rotating shaft 10 until the horizontal state, so as to avoid the influence of strong wind on the photovoltaic support and the photovoltaic panel 2.

[0040] When the wind speed is small, the photovoltaic panel 2 does not need to be in a horizontal state in order to improve the use efficiency of the photovoltaic panel 2. The wind blows the photovoltaic panel 2 and drives the bottom plate 18 to slide in the bottom box 1, and the second springs 21 are elastically deformed and buffer and absorb shocks.

[0041] When it is necessary to maintain and overhaul the photovoltaic support and the photovoltaic panel 2, the first magnetic blocks 22 and the second magnetic blocks 23 are started and the magnetic properties of the mutually close sides are made to be of the same kind, so as to fix the position of the bottom plate 18 and prevent the photovoltaic support and the photovoltaic panel 2 from shaking.
