Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and in particular to a special mounting bolt for photovoltaic brackets. Background Art

[0002] Photovoltaic bracket is a structural frame used to install and support photovoltaic panels. It is usually made of metal materials (such as aluminum alloy, stainless steel, carbon steel, etc.) and has high strength and stability. The design and installation of photovoltaic brackets have an important impact on the performance and safety of photovoltaic power generation systems.

[0003] The main functions of photovoltaic brackets:

[0004] Supporting photovoltaic panels: Photovoltaic brackets provide stable support for photovoltaic panels, ensuring their safe operation in all weather conditions;

[0005] Adjust the installation angle: The photovoltaic bracket can adjust the installation angle of the photovoltaic panel to achieve the best sunlight absorption and improve power generation efficiency;

[0006] Protect photovoltaic panels: Photovoltaic brackets can protect photovoltaic panels from external environmental influences such as wind, rain, snow, etc., extending their service life;

[0007] Easy installation and maintenance: The photovoltaic bracket adopts a modular design, which is convenient for the installation and disassembly of photovoltaic panels and is conducive to the maintenance and upgrade of the system.

[0008] Types of photovoltaic brackets:

[0009] Fixed bracket: The fixed bracket installs the photovoltaic panel at a fixed angle and position, which is suitable for areas with sufficient sunlight and clear irradiation direction;

[0010] Adjustable bracket: The adjustable bracket can adjust the installation angle and direction of the photovoltaic panel to adapt to sunlight exposure in different seasons and weather conditions.

[0011] At present, since the conventional bolt lengths are all fixed sizes, when used for the installation of some photovoltaic brackets, due to the different hole depths of the brackets, bolts of different lengths need to be customized. During installation, if a bolt of a certain size is missing, it will directly lead to the inability to install the photovoltaic bracket or local instability after installation. Utility Model Content
