Abstract

A telescopic draught fan foundation is used for supporting a draught fan body and comprises a bearing platform structure, a telescopic base connected with the bearing platform structure and a plurality of mooring systems connected with the bearing platform structure. The telescopic base comprises at least three telescopic column assemblies, and each telescopic column assembly comprises an inner stand column and an outer stand column which are connected through a locking adjusting mechanism, wherein the inner stand column stretches out, draws back and is limited in the outer stand column through the locking adjusting mechanism. According to the telescopic draught fan foundation, by means of the telescopic function of the stand columns, switching of multiple working states can be achieved, the telescopic draught fan foundation can cope with large water depth change conditions near the coast in China, can adapt to different working states and can be matched with the different types of mooring systems, so that the engineering universality of the design is greatly improved.

Description

technical field [0001] The invention relates to a retractable fan foundation and a fan. Background technique [0002] In recent years, during the development and utilization of wind energy, a renewable energy source, wind turbines have gradually shifted from land to offshore, and then 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, European and American countries are in a leading position in the research and development capabilities and investment of floating wind turbine foundations. Among them, the most representative types of floating wind turbine foundations include: [0004] The Hywind (single column foundation) developed by Equinor consists of a lower floating bo...
