Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to a roof photovoltaic bracket for color steel tile buildings. Background Art

[0002] With the global emphasis on renewable energy and policy promotion, solar photovoltaic, as a clean, renewable, and pollution-free energy form, has seen rapid development in its technology research and development and application. The photoelectric conversion efficiency of photovoltaic modules has been continuously improved, and the cost has been continuously reduced, making the application of solar photovoltaic power generation in the building field more and more extensive. Especially on the roofs of urban and rural buildings, installing a photovoltaic system using the idle roof space of color steel tile buildings can not only achieve energy self-sufficiency and reduce electricity costs but also meet the requirements of green buildings and energy conservation and emission reduction. Color steel tiles are widely used in the roofs of various buildings due to their light weight, weather resistance, convenient construction, and diverse shapes. However, its special corrugated structure and material properties pose certain challenges to the installation of photovoltaic brackets. First, the color steel tile roof requires the photovoltaic bracket to have good adaptability and a non-destructive installation method to protect the roof structure. Second, the load-bearing capacity of the color steel tile roof is limited, and the photovoltaic bracket system needs to be designed with light weight while ensuring the safety and stability of the overall structure.

[0003] The Chinese patent document in the prior art: 202310179272.1 discloses a photovoltaic panel bracket, which includes: a first bracket, a second bracket, an installation cable, and a support frame. The first bracket and the second bracket are spaced apart in the first horizontal direction; the installation cable is connected between the first bracket and the second bracket; the support frame includes a frame body and a support portion. The support portion is provided on the frame body and is connected to the installation cable. The frame body includes a first connection portion and a second connection portion that are opposite in the first horizontal direction. The first bracket includes a plurality of first installation portions, and the plurality of first installation portions are spaced apart in the up and down direction.
