Offshore wind power suction pile foundation

The utility model relates to the technical field of offshore wind power facility structures, in particular to an offshore wind power suction pile foundation. The suction pile comprises a fan tower, atower frame, a suction pile connecting section and a suction pile body. The force arm of resultant force of wave current load to the suction pile body is reduced through inward deviation of the lowerend of the connecting column; therefore, under the condition that the wave current load is not changed, the overturning moment of the wave current load on the suction pile body is reduced compared with the prior art; the problem that in the prior art, due to the fact that the wave current load in the horizontal direction is too large, soil around the suction pile body fails is solved, the weight of the tower can be properly reduced, the steel consumption of the tower is reduced, and the cost is reduced. 本实用新型涉及海上风电设施结构技术领域，特别涉及一种海上风电吸力桩基础；包括风机塔筒、塔架、吸力桩连接段和吸力桩本体；通过连接柱下端向内偏移而减小波流荷载对吸力桩本体的合力的力臂，从而在波流荷载大小不变的情况下相比现有技术降低了波流荷
