<p>PURPOSE:To facilitate to reduce stability factors in the strength of the device by a method wherein a construction, in which a wind mill and a generator are enabled to move up-and-down freely along a supporting tower so as to be capable of ascending and descending them to any requested height. CONSTITUTION:The main body 3 of an aerogenerator, having wings 2 and a generator 8, is provided to be capable of ascending and descending along a supporting tower 10, and generates electricity by elevating it to the high sky to receive wind at normal times while it is descended to the ground or a safe height beforehand to avoid a strong wind in case there is fear to receive a damage on the device by the strong wind or the like. According to this method, a structural strength capable of withstanding against the abnormal strong wind, is made unnecessary. The maintenance, inspection, repairing and the like of the device may be effected at a position near the ground, therefore, these works may be facilitated.</p> |
