The invention discloses floating fan equipment for a medium-depth
water area. The floating fan equipment comprises a wind
turbine generator, a fan
tower, a floating foundation and a
mooring device from top to bottom. The wind
turbine generator is mounted at the upper end of the fan
tower; the lower end of the fan
tower is fixed on the floating foundation; and the
mooring device is connected to thefloating foundation and is used for
mooring equipment on a
seabed. The floating foundation comprises a main stand column, four auxiliary stand columns and a cross-shaped
buoy. The four auxiliary stand columns and the cross-shaped
buoy are symmetrically distributed relative to the main stand column in space, the four auxiliary stand columns are connected to the four ends of the cross-shaped
buoy respectively, the top faces of the four auxiliary stand columns are distributed at the four corners of the square
projection plane, the cross-shaped buoy intersects on the central axis of the floatingfoundation, and the main stand column stands over the intersection of the cross-shaped buoy. An
effective solution is provided for development of the floating
wind power technology in the medium-water-depth sea area within 30-100 m; the structure is simple and stable, the foundation construction difficulty and manufacturing cost are not high, draught is deep, and the
wave resistance is good; and the requirement for development of
wind power generation in the
coastal sea area is quite met.
