Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment, and in particular to a multi-scale adjustable photovoltaic bracket. Background Art

[0002] Photovoltaic brackets are metal structural brackets used to install, support and fix solar panels (photovoltaic modules) in solar power generation systems. The main function of photovoltaic brackets is to ensure that photovoltaic panels remain stable under various weather conditions, while adjusting the orientation and angle of photovoltaic panels to maximize the reception of solar radiation, thereby improving the absorption efficiency and conversion efficiency of solar energy. The design and selection of photovoltaic brackets are crucial to the overall performance and life of photovoltaic systems.

[0003] Photovoltaic brackets can be divided into fixed brackets and adjustable brackets according to different adjustment angles. Fixed brackets are suitable for scenarios with relatively stable solar energy resources and large-scale installations (the cost of brackets and the ease of installation need to be reduced), while adjustable brackets can be further divided into inclination-adjustable brackets and automatic tracking brackets. Although the latter can actively track the trajectory of the sun to further increase power generation, the need to be equipped with sensors and control processor equipment greatly increases the cost; therefore, inclination-adjustable photovoltaic brackets are more advantageous in small-scale application scenarios such as residential and commercial buildings.

[0004] The existing photovoltaic brackets with adjustable tilt angles on the market have poor adjustment range and accuracy during the adjustment process due to the limited flip angle of the supporting structure and the difficulty in fine-tuning the flip subdivision.
