Abstract: A wind-driven electric plant includes a mast with a windwheel and a generator in a nacelle and a shielding chamber with a base, walls, and a cover. The mast is coupled to the nacelle and mounted in the shielding chamber. The mast may comprise a set of sections pivotally connected to each other such that the mast has the capability of folding and spreading, or the mast may comprise a set of telescoping or folding and spreading sections. A mast transfer mechanism is configured to move the mast between an operating position with the windwheel outside the chamber and a stored position with the windwheel inside the chamber.

Abstract: A wind-driven electric plant includes a mast with a windwheel and a generator, a shielding chamber with a base, walls and a cover. According to one embodiment, said mast is attached to the shielding chamber base by a fastening-lifting device attached to a mast transfer mechanism for stowing the mast into the chamber or placing the mast into operating position. The mast comprises a set of pivotally connected sections, with the ability to fold and spread, preferably under the control of an automatic control device. In a second embodiment, the mast comprises a set of telescoping sections attached to a post, rigidly fastened to the base of the chamber, with the ability of the mast vertical movement therein. Both embodiments preferably comprise both manual control and automatic remote control. Also, both embodiments preferably comprise a mechanism for opening and closing the shielding chamber cover connected to an automatic control device.
