Abstract

A floating body type wind power generation device is provided with: a floating body floating on the water surface; and a windmill installed on the floating body and configured so that at least part of it can be submerged. The floating body type wind power generation device is characterized in that the windmill includes at least one blade. ; The hub, on which the blades are installed; the tower, which is erected on the floating body; the nacelle, which is disposed on the tower; the first electrical equipment, which is provided on the hub or the nacelle; and the second electrical equipment, The second electrical device is connected to the first electrical device via a cable, and the second electrical device is configured to be relatively movable in the vertical direction relative to the tower so as not to be submerged in water when the windmill dives.

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 and a windmill installed on the floating body, and a component transportation method of the device. Background technology [0002] In recent years, from the viewpoint of protecting the global environment, wind power generation devices have become increasingly popular. In particular, plans to install large-scale wind power generation devices, which are advantageous for improving power generation efficiency, on water such as the sea or lakes are progressing in various places. [0003] As a wind power generation device installed on the water, a floating body type wind power generation device in which a windmill is installed on a floating body floating on the water surface is known. Floating wind power generation devices include large-scale devices with tower heights ranging from tens of meters to more than 100 meters...
