Abstract

The invention discloses a semi-submersible floated draught fan foundation adopting a rotor mooring system and a draught fan. The semi-submersible floated draught fan foundation comprises a semi-submersible floating platform and the rotor mooring system, wherein the semi-submersible floating platform is fixedly connected with a draught fan main body and used for floating the draught fan on the sealevel; and the rotor mooring system comprises a rotor part and a stator part which can rotate relative to each other, the rotor part is fixedly connected with the semi-submersible floating platform, the stator part is moored to the seafloor through anchor chains, and the rotor part drives the semi-submersible floating platform to rotate freely around the central axis of the rotor mooring system together. The semi-submersible floated draught fan foundation is suitable for the conventional water depth range of about 50 m in China, and has the wind vane effect that can adjust a foundation azimuthangle according to the environmental load of the draught fan foundation, and thus the actual demand of the current domestic offshore wind farm development is met.

Description

technical field [0001] The invention relates to a floating fan foundation, in particular to a semi-submerged floating fan foundation and a fan. Background technique [0002] In recent years, in the process of human development and utilization of wind energy in renewable energy, wind turbines have gradually shifted from land to offshore, and gradually from offshore to deep sea. During this process, a variety of forms of offshore floating wind turbine foundations have emerged. Among them, there are four types: single column type (SPAR), semi-submersible (Semi-Submersible), tension leg type (TLP) and ship type (Barge). Types of floating fan foundations are the most common. [0003] At present, western countries, especially European countries, are far ahead of my country in terms of research and development capabilities and investment in the foundation of floating wind turbines. Among them, the most representative types of floating fan foundations, such as the Hywind (single c...
