FOLDABLE WIND-DRIVEN POWER PLANT Russian patent published in 2024 - IPC F03D13/20 

FIELD: wind power engineering.

SUBSTANCE: invention relates to wind power engineering, namely to foldable wind-driven power plants. Foldable wind-driven power plant comprises a stand with a wind generator equipped with a mechanism for its rotation relative to the vertical axis of the stand in the direction of wind according to readings of an anemometer. On the base of the post there is a lug connected by a horizontal axis with a bracket fixed on the main plate of the foundation, and made with possibility of inclination of the post relative to the horizontal axis to the support surface and lifting to a vertical position by means of a winch. On both sides of the post there are two additional supports designed to take up wind loads acting on the wind generator and combined in the upper part by a holder made in the form of a catcher for gripping and fixing the post in a vertical position by means of two electromagnetic stoppers installed on the holder. Each support is made in the form of two trusses located at an angle to each other and to the foundation, combined by a common vertical rod, fixed in the upper part together with the inclined rods of the trusses on the holder, and in the lower part together with the trusses rods on the bracket equipped with a screw jack, which plate is fixed on the main foundation plate. Each truss is equipped with an additional screw jack, the plate of which is fixed on the additional foundation plate. Winch is installed on the main foundation plate, and its cable passes through the unit installed on the holder and is fixed on the clevis installed on the post in its middle part.

EFFECT: reduction of labour intensity, simplification of operation and reduction of costs when lifting and lowering the rack during installation and carrying out maintenance without the use of high-capacity cranes, reduced requirements for preparation of the site for installation of the plant due to availability of screw jacks, increased reliability of gripping and holding the post due to the catcher and stoppers.
