[0002] The roof photovoltaic power generation assembly is generally installed on the roof through a bracket. In different seasons and under different weather conditions, the wind direction at the roof is different. In order to receive more sunlight, the area of each photovoltaic panel is large and is arranged towards the sunlight. When strong wind blows at the roof, if the wind direction is at a large angle with the back of the photovoltaic panel, a large pulling force will be generated between the photovoltaic panel and the fixed frame, which will pull the photovoltaic panel from the bracket or pull the entire frame together with the photovoltaic assembly from the roof, damaging the photovoltaic assembly or the structure of the roof. How to make the roof photovoltaic panel mounting bracket have the functions of wind guiding and wind following and maximize the wind resistance function has become a problem to be solved in the installation of the roof photovoltaic bracket.

The top end of the upper end buffer spring is connected to the upper end of the X-shaped frame. The top end of the lower end buffer spring is connected to the lower end of the X-shaped frame. The four corners of the photovoltaic panel are flexibly connected to the buffer springs.

If the strong wind enters the right-angled triangular three-dimensional frame from the lower side of the left of the right-angled triangular three-dimensional frame and blows vertically on the lower bottom surface of the photovoltaic panel, the entire photovoltaic panel rotates and swings around the rotatable sphere, the left end of the photovoltaic panel is lifted upward, the upper end buffer spring on the left and the lower end buffer spring on the left are simultaneously elongated, the right end of the photovoltaic panel is pressed downward, and the upper end buffer spring on the right and the lower end buffer spring on the right are simultaneously compressed; thereby the blowing direction of the strong wind is changed with the angle of the lower bottom surface of the photovoltaic panel, the strong wind is changed in direction and guided out to the outside of the photovoltaic panel, and the wind force of the strong wind pulling up the photovoltaic panel is reduced.
