In addition, in order to ensure the light receiving effect of the photovoltaic panel, most of the existing photovoltaic brackets are triangular frame structures. When subjected to strong winds, due to the large area of ​​the installed photovoltaic panels, the resistance is relatively large, causing the photovoltaic bracket to fall over and be damaged easily.

[0012] The push block is an isosceles trapezoidal structure, and the two oblique sides of the isosceles trapezoid face the vertical plate of the limiting block and are slidably matched with the inclined surfaces on the vertical plate.

[0013] The inclined beam is also connected to multiple supporting beams, and photovoltaic panels are laid on the supporting beams; the rotating motor and electromagnetic brake of the rotator and the propulsion motor of the limit device are all electrically connected to the controller, and the controller is also electrically connected to the solar automatic tracking sensor; the controller controls and adjusts the angle of the photovoltaic panel to make it perpendicular to the sunlight according to the signal sensed by the solar automatic tracking sensor.
