The invention relates to the technical field of offshore wind power foundations, in particular to a floating type offshore wind power foundation, and aims to solve the problem that the stability of an existing semi-submersible type offshore wind power foundation needs to be improved. In order to achieve the purpose, the floating type offshore wind power foundation comprises a middle column, three side columns, a heaving plate and a ballast tank, the upper end of the middle column is used for being connected with a tower column of an offshore wind turbine generator, a first cavity is formed in each side column, and the three side columns are evenly distributed around the middle column; the heaving plate comprises three first circular plates connected to the lower ends of the three side columns respectively, a second circular plate connected to the lower end of the middle column and three strip-shaped plates connected with the first circular plates and the second circular plate respectively, the diameters of the first circular plates and the second circular plate are the same, and the lower surfaces of the three first circular plates are connected to the ballast tank through rigid rod pieces respectively; the upper end side portions of the side columns are connected with the upper end side portions of the middle columns through connecting pieces, in the using state, the tops of the side columns are not smaller than 5 m higher than the sea surface, and the depth of the portion, below the sea surface, of the ballast tank is not smaller than 30 m.
本发明涉及海上风电基础技术领域,具体提供一种漂浮式海上风电基础,旨在解决解决现有半潜式海上风电基础的稳定性有待提高的问题。为此目的,本发明的漂浮式海上风电基础包括一中柱、三个侧柱、一垂荡板和一压载舱,中柱的上端用于连接海上风电机组的塔柱,侧柱内具有第一腔室,三个侧柱绕中柱均匀分布,垂荡板包括三个分别连接至三个侧柱下端的第一圆板、一连接至中柱下端的第二圆板以及三个分别连接第一圆板和第二圆板的条形板,第一圆板和第二圆板的直径相同,三个第一圆板的下表面分别通过刚性杆件连接至压载舱,侧柱的上端侧部与中柱的上端侧部通过连接件连接,在使用状态下侧柱的顶部高于海面不小于5m,压载舱位于海面下方的深度不小于30m。
