A floating fan foundation and fan

Abstract

The invention discloses a floating fan foundation, comprising: a support structure, which is located at the center of the floating fan foundation, and is connected with the main body of the fan for supporting the main body of the fan; a floating structure, which is located around the support structure, and is connected with the support Structural connection, used to provide buoyancy for the foundation of the wind turbine; mooring system, connected to the floating structure, used to position the foundation of the floating wind turbine; the floating structure includes at least three floating body structures and at least three connecting structures, and the The connecting structures are respectively fixedly connected to two adjacent floating body structures. The floating structure of the present invention adopts the form of double-layer outer plates. In addition to increasing the strength of the outer plates, the thickness of the outer plates is reduced, and the amount of steel used is saved. The floating structure is connected to the middle cylinder through a connecting bridge, which is convenient for staff to operate and maintain. The foundation of the floating wind turbine uses less steel and has high safety, and is suitable for transitional deep water areas.

Description

technical field [0001] The invention relates to the technical field of offshore wind power foundations, in particular to a floating fan foundation and a fan. Background technique [0002] With the deepening of human understanding of offshore wind resources and the advancement of wind energy development technology, the development of wind resources has developed from near and shallow seas to deep and distant seas. Floating wind turbine foundation is one of the key equipment for deep sea wind energy development. On the basis of oil and gas development technology, various forms of floating foundations have appeared in recent years, among which semi-submersible floating foundations can be installed and debugged on the shore, and then towed to the installation area, which has high flexibility and wide application range , Low installation cost and other advantages, so it has developed rapidly. [0003] Many international companies and research institutions have proposed the conc...

AI Technical Summary

Problems solved by technology

Existing semi-submersible floating fan foundations often use large-diameter, large-wall-thick cylinder structures to provide buoyancy, which increases the construction technical threshold and the amount of steel used, and increases production costs. Moreover, small-diameter buoys are used between large-diameter The cross brace structure connection is prone to fatigue damage, and the safety is difficult to guarantee

In addition, the existing floating foundation basically adopts a catenary mooring system with a catenary full anchor chain, which is expensive and not suitable for transitional water depth areas.
