Floating-body type wind power generating device

Abstract

A purpose of the present invention is to provide a floating-body type wind power generating device equipped with a mooring device capable of securely mooring a floating body against drift force and turning moment. Provided is a floating-body type wind power generating device (1) equipped with a floating body (20) which floats on a water surface, a wind power generator (10) provided to the floating body, and a mooring device (36) for mooring the floating body. In a planar view, the floating body (20) forms a virtual triangle shape having three vertices. The mooring device (36) includes: a first mooring cable (34b) which is connected to, from among the three vertices of the virtual triangle shape, one of the two vertices excluding the vertex having the largest internal angle, or in cases when there are two or more vertices having the largest internal angle, one of the two vertices excluding an arbitrary vertex from among the two vertices which have the largest internal angle; and a second mooring cable (34c) which is connected to the other of the two vertices. In a planar view, the first mooring cable and the second mooring cable are separated from the floating body (20), each extending in a direction which intersects the other.

Description

technical field [0001] The present invention relates to a floating body type wind power generator including a floating body floating on the water surface, a wind power generator installed on the floating body, and a mooring device for retaining the floating body. Background technique [0002] When a wind power generator is installed on the sea or the like, a bottom-mounted wind power generator in which a foundation is placed on the bottom of the water and a wind turbine is installed thereon is generally used in an area where the water depth is relatively shallow. However, in a region where the water depth is relatively deep, the above-mentioned bottom-mounted wind power generation device is uneconomical, so studies have been made to adopt a floating body type wind power generation device. [0003] As a conventional floating body type wind power generator, a wind power generator in which a wind power generator is installed on a floating body floating on the water surface is k...
