Abstract

A floating-body type wind power generation device equipped with a floating body, which floats on the surface of water, and a windmill, which is installed on the floating body and at least a portion of which is submersible, said floating-body type wind power generation device being characterized in that the windmill includes at least one blade, a hub attached to the blade, a tower erected on the floating body, a nacelle provide on the tower, a first electrical device provided in the hub or the nacelle, and a second electrical device connected to the first electrical device via a cable, and in that the second electrical device is constructed so as to be capable of relative movement in a direction perpendicular to the tower when the windmill is submerged, so that the second electrical device is not submerged.

Description

technical field [0001] The present disclosure relates to a floating body type wind power generation device including a floating body floating on the water surface, a wind turbine installed on the floating body, and a component conveyance method of the device. Background technique [0002] In recent years, from the viewpoint of protection of the global environment, wind power generators have become popular. In particular, plans to install large-scale wind power generators that contribute to the improvement of power generation efficiency on water such as seas and lakes are progressing in various places. [0003] As a wind power generator installed on water, a floating body type wind power generator in which a windmill is installed on a floating body floating on the water surface is known. Floating body wind power generation devices include large-scale devices whose tower heights range from several tens of meters to more than one hundred meters. In such a floating wind power ...
