Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic frames, and in particular relates to a wind-resistant solar photovoltaic frame. Background Art

[0002] Existing photovoltaic frames are assembled from an integrally formed frame, which requires an angle code mounting cavity and a base plate for fixing the bracket. In view of the influence of wind, most of them are divided into two types, which directly transmit wind power to the top or bottom surface of the photovoltaic module.

[0003] For wind forces from top to bottom, the wind resistance of the photovoltaic frame can be improved by simply increasing the strength of the photovoltaic bracket or lowering the height of the photovoltaic bracket.

[0004] However, if the wind blows from bottom to top, the photovoltaic modules will be lifted up by the wind, and the existing connection between the photovoltaic frame and the bracket is mainly made by bolts, which need to be used to resist the wind force, and the wind at the bottom of the photovoltaic module cannot be effectively guided out. Therefore, the wind resistance is insufficient, which will cause the photovoltaic modules and photovoltaic frames to be lifted up and detached from the bracket. In severe cases, the bracket may also be blown away or scattered, resulting in insufficient safety and service life. Summary of the invention

[0005] The purpose of the present invention is to provide a wind-resistant solar photovoltaic frame. By designing a separate component mounting shell and a lower frame, a connector with upper and lower buffering functions and no space occupation is used for connecting and fixing the component mounting shell and the lower frame. When the wind blows from the bottom of the photovoltaic frame, it can have a certain buffering capacity and can increase the space between the component mounting shell and the lower frame, which is beneficial to the discharge of wind force and reduces the problem of photovoltaic components being lifted up by wind force.
