Fan foundation structure

The utility model discloses a fan foundation structure in the technical field of fan foundation structures, which comprises a fan support component, and a wind power generation component is mounted at the top of the fan support component. The supporting base can limit and support a wind power generation assembly mounted at the top of the bottom surface bearing mechanism, the supporting base can perform disassembly and assembly connection and maintenance and replacement operation on the pre-embedded base according to the use condition in cooperation with a connecting screw groove and a connecting screw head structure, meanwhile, the stability of connection between the pre-embedded base and the supporting base can be effectively improved, and the service life of the pre-embedded base is prolonged. When the pre-embedded seat is pre-embedded, the pre-embedded seat can go deep into soil through the soil piercing cone structure, and the pre-embedded groove structure is matched, so that the supporting gravity center
