WIPO Patent Application WO2017010206
Kind Code:
A1
Abstract:
This maintenance method includes: a step (S32) for fixing a blade, of a rotor of a wind power generation facility, to be horizontalized; a step (S33) for changing the pitch angle θ, of the blade that is to be horizontal, from that in a wind receiving state; and a step (S22) for causing an unmanned flying machine to reach the horizontalized blade and perform a maintenance task for the blade. Preferably, the maintenance task includes a defect inspection of the blade. Thus, the present invention is capable of providing a maintenance method for a wind power generation facility which enables maintenance tasks for blades of a wind power generation facility while reducing burden on a worker and suppressing time and cost that are required for inspection.
