Single point mooring type deep sea floating type draught fan

The invention relates to a single point mooring type deep sea floating type draught fan. The single point mooring type deep sea floating type draught fan comprises a semi-submersible floating type foundation (1), mooring cables (2), tower columns (3), a power generation cabin (4) and a wind wheel (5). The single point mooring type deep sea floating type draught fan is characterized in that the floating type foundation comprises three stand column type cylindrical structures (11) which are arranged in a triangular shape; each stand column type cylindrical structure (11) is provided with a pressurized-water plate (12); the stand column type cylindrical structures (11) are connected through trusses (13); one of the three stand column type cylindrical structures (11) is a main stand column, the tower columns (3) are fixed to the main stand column, and the lower end of the main stand column is provided with a single point device (14); and the multiple mooring cables are arranged, one ends of the mooring cables are moored at different positions of a seabed, and the other ends of the mooring cables are fixed to the single point device (14). The single point mooring type deep sea floating type draught fan has the automatic yaw control capability, and the power generation efficiency of the floating type draught fan can be improved.
