Description

[0002] In recent years, with the rapid development of photovoltaic power generation technology, the stability and adjustability of photovoltaic support systems have become key factors in improving power generation efficiency. However, the following technical bottlenecks still exist in existing technologies: Insufficient stability of the connection between the ground pile and the column pile: Traditional photovoltaic (PV) mounting systems typically use welding or flange connections to fix ground piles and columns. These rigid connections are prone to shifting in soft soil or strong winds and lack adjustability. Furthermore, it is difficult to fine-tune the height of the ground piles after installation to adapt to the terrain, thus limiting the overall height of the mounting system and affecting land utilization.

[0003] Angle adjustment function missing: Multi-angle adjustment mechanisms are insufficient to meet the needs of complex terrain: existing column connectors mostly adopt a fixed tilt angle design, which cannot be adjusted. When encountering irregular terrain such as slopes and hills, the photovoltaic panel array is difficult to form an effective plane, resulting in a deviation of more than ±5° in the light-receiving angle of the photovoltaic modules, which significantly reduces the power generation efficiency per unit area.

[0004] Low installation efficiency and standardization: Therefore, those skilled in the art urgently need to provide a multi-angle adjustable and stable connector for photovoltaic system columns that facilitates height and angle adjustment. Utility Model Content
