[0049] Since the solar photovoltaic panel bracket is exposed to the outdoor environment for a long time, it is greatly affected by the natural environment, especially the wind. The wind-affected surface is mainly concentrated on the solar photovoltaic panel. When the photovoltaic panel is at different working conditions, the wind-receiving area of ​​the photovoltaic panel is different, and the flow rate around the photovoltaic panel is also different, so that the photovoltaic panel bears different wind loads; as the main windward surface, the solar photovoltaic panel mainly bears the wind load, and then transmits the load component to the main beam and column through the purlin under the photovoltaic panel; there are two forms of displacement of the photovoltaic bracket under the wind load. One is that the wind load causes the column to bend and deform, resulting in the traction displacement of the main oblique beam connected to the column, and the other is the local displacement deformation of the photovoltaic bracket components. When the wind load is loaded on the solar photovoltaic panel at different operating angles, the downward force on the purlin will make the rotation trend around the main beam axis similar. Under the influence of wind load, the photovoltaic bracket will have a torsion tendency and displacement in the YZ plane. When the control angle increases, the panel load area increases, and the tendency of torsion tendency and displacement also increases at the same time. Therefore, during the actual construction process, the main beam of the photovoltaic bracket should be reinforced against torsion along the windward side, and the connection between the photovoltaic panel and the main inclined beam and purlin should be reinforced for the second time to reduce the displacement and deformation of the photovoltaic bracket and increase the anti-overturning stability.

[0050] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
