A foldable wind-driven power plant comprises a stand, having a wind generator
installed in its upper part, mounted on a main support and configured to tilt
into a
horizontal position and lift into a vertical position, and a main winch, where
the
plant is equipped with an auxiliary winch mounted on an additional support
provided with a seat and installed on a separate foundation. The main support
consists of a fixed base and a rotary part installed thereon with the
possibility to
turn in the horizontal plane around a vertical axis. The base enables the
downwind
rotation of the stand mounted on the rotary part and embodied in the form of a
vertical wing realized on the basis of a spatial frame, the elements of which
are
only subjected to compression or tension, and are covered with a shell. The
cross-
section of the wing has a symmetrical aerodynamic profile, while the vertical
axis
of rotation of the stand is located in front of the aerodynamic focus of the
wing,
thus, enabling the stand to feather downwind. Furthermore, the lower part of
the
stand contains a hinge, which enables the rotation of the stand around the
horizontal axis and divides the stand post into a non-tilting beam containing
rope
transfer blocks of the main winch mounted on the fixed base, which are distant
from the axis of rotation, and a tilting-lifting part containing in its
section the blocks
for securing such ropes, which are distant from the hinge. Furthermore, the
upper
part of the stand contains the point of attachment of the auxiliary winch
rope.
