Floating fan equipment for medium-depth water area

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of offshore wind power generation, in particular to floating wind turbine equipment for medium-depth waters. Background technique [0002] Fossil resources such as oil and natural gas are facing the challenge of clean energy such as wind energy and solar energy. It is imperative to develop new sustainable energy. As a clean renewable energy, wind energy has huge reserves and has attracted attention from all over the world. Gradually become an important source of electricity. [0003] At present, onshore wind power generation technology is very mature, and the development of offshore wind energy is becoming the main development direction of wind energy. Since 2000, the newly installed capacity of offshore wind power in the world has continued to increase. As of 2019, the cumulative installed capacity of global offshore wind power reached 27.2GW. The construction of offshore wind farms draws lessons from th...

AI Technical Summary

Problems solved by technology

At present, the working water depth of offshore floating wind turbines put into use in foreign countries is about 100m. For shallow waters with a water depth of 30-100m, although there are related floating wind turbine concepts, there are few engineering demonstrations, and there is no large-scale commercial power generation operation.
