Abstract

A semi-submersible floating wind power generator includes a wind power generator set, a post device, a load carrying device and a mooring device. The wind power generator set is disposed at a first end of the post device. The load carrying device is disposed at a second end of the post device. The mooring device is disposed at the second end of the post device. The post device includes a main post and multiple auxiliary posts. The main post is disposed in parallel with the multiple auxiliary posts, and second ends of the multiple auxiliary posts are aligned such that the second ends of the multiple auxiliary posts form a first plane, and the second end of the main post is disposed at a position closer to the first end of the main post than the first plane.
