Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support construction technology, specifically to a photovoltaic support foundation. Background Technology

[0002] Photovoltaic support structures are crucial for installing photovoltaic panels. The foundation beneath these support structures includes micro-hole cast-in-place pile foundations, PHC pipe piles, and spiral steel pipe pile foundations. Micro-hole cast-in-place piles are widely used in mountain photovoltaic projects. During construction, holes are pre-drilled underground, a reinforcing cage is placed, concrete is poured and vibrated, and the lower column is connected to the pile foundation before the concrete pile foundation initially sets. Then, concrete is poured on the ground to form a stable support. The position of the reinforcing cage and the connection position of the embedded parts with the lower column after the concrete foundation is poured directly affect the verticality and alignment of the lower column after construction, thus affecting the installation quality of the subsequent photovoltaic support structures and photovoltaic panels. In conventional photovoltaic support pile foundation construction, when placing the reinforcing cage, pouring concrete, and vibrating, it is difficult to fix the position of the reinforcing cage concentric with the pile hole, causing the pile foundation to shift. The position of the embedded parts on the pile foundation is fixed, and it is difficult to adjust them to ensure that the lower column meets the design requirements when connecting them.

[0003] Utility model patent CN221167897U discloses a photovoltaic support foundation, including a cup-shaped foundation, a column, and several cable assemblies. The cup-shaped foundation is fixedly set on the ground, and the bottom end of the column is inserted into the cup-shaped opening of the cup-shaped foundation. Fine aggregate concrete is filled between the bottom end of the column and the cup-shaped opening of the cup-shaped foundation. Several cable assemblies are spaced apart around the circumference of the column. Each cable assembly includes a first steel cable, a tensioning device, and a second steel cable. One end of the first steel cable is set on the outer wall of the column, and the other end is connected to the second steel cable through the tensioning device. The end of the second steel cable away from the tensioning device is connected to a ground nail for fixing in the ground. The column is fixed to the cup-shaped foundation with fine aggregate concrete. The column is fixed by a first steel cable, a tensioning device, a second steel cable, and ground nails, thus ensuring reliable installation of the column on the cup-shaped foundation. This method offers fast on-site construction, short cycle time, high construction quality, structural safety and reliability, and time savings. Furthermore, the foundation can be factory-produced and installed on-site, resulting in low cost and economy. However, in this patent, the position of the cup-shaped foundation is fixed by several cables, thereby fixing the photovoltaic bracket and photovoltaic panel. In actual use, photovoltaic brackets and photovoltaic panels are usually built in mountainous or other outdoor areas with strong winds and sandstorms. During use, the ground nails inserted into the ground can easily shift, causing the cables to loosen, leading to displacement and damage to the photovoltaic bracket and photovoltaic panel, thus affecting the normal operation of the entire photovoltaic system.
