Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic components, and in particular relates to a photovoltaic array pile foundation component. Background Art

[0002] Due to the wide layout of photovoltaic construction projects, the terrain encountered during the construction process is also quite diverse. The use of screw piles in pile foundation construction has a higher construction efficiency, but it needs to be used under good geological conditions. The use of cast-in-place piles has the advantage of a wide range of terrain adaptability and can be used under poor geological conditions, but the construction efficiency is lower than that of screw piles. Therefore, a set of pile foundation parts with cast-in-place piles and screw piles is required to adapt to pile foundation construction in different geological conditions.

[0003] The patent document with announcement number CN206090560U discloses a pre-drilled steel anchor pile for installing a photovoltaic module support, including a steel cage and a foundation pile embedded part. The steel cage is placed in the hole to be installed on the ground, one end of the foundation pile embedded part is connected to the steel cage by welding, and the other end is exposed to the ground for installing and fixing the support column. However, the top of the utility model does not have a structure for conveniently fixing the photovoltaic module. Utility Model Content
