Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic brackets, and in particular relates to a roof photovoltaic bracket that is wind-resistant and easy to install. Background Art

[0002] For rooftop photovoltaic systems, due to the high height of the roof itself, it is greatly affected by wind, so there will be problems with insufficient stability, especially for the installation angle requirements of the photovoltaic system, that is, the existence of an angle can greatly increase the light-receiving area and efficiency.

[0003] However, due to the installation angle, one side of the photovoltaic system is in a lower state, the other side is in a higher state, and the other two sides are in a triangular state. Therefore, only the low side has wind protection ability, and the other three sides are at risk of wind penetration, resulting in poor wind resistance.

[0004] If a photovoltaic system is designed with a central height that decreases on all four sides, the wind resistance and stability of the photovoltaic system can be greatly improved. However, the structure will be complex and difficult to install. Similarly, due to the different heights at various positions, the lengths of the beams that make up the photovoltaic bracket will be different, thus affecting production costs and assembly efficiency.

[0005] Therefore, designing a photovoltaic bracket that is easy to install and has strong wind resistance is a problem that needs to be solved by workers in this field. Summary of the invention

[0006] The purpose of the present invention is to provide a roof photovoltaic bracket that is wind-resistant and easy to install. By designing a new type of support frame to form component brackets, the height of the cross beams on the support frame is gradually reduced and the cross beams themselves have an inclination, thereby forming a sub-frame body with a high corner and another low corner. Four sub-frame bodies form a bracket system with a high center and four sides that gradually decrease, so that the highest height of the four sides of the photovoltaic system is also relatively low, which is conducive to the arrangement of wire troughs on the outside. Not only can the wires be concentrated, but the sides of the photovoltaic system can also be sealed, thereby greatly improving the wind resistance of the photovoltaic system.

[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
