MOBILE ARCTIC WIND FARM Russian patent published in 2022 - IPC F03D3/06 F03D80/70 F03D9/30 

FIELD: wind energy.

SUBSTANCE: invention relates to the field of wind energy and is intended for use in the Arctic regions. The mobile arctic wind farm contains a vertical shaft of rotation, in which the working bodies are blades inserted into the slots of the blades with clamps. The vertical shaft has permanent magnet bearings at the ends. In the upper part, stretch marks are attached to the bearing housing to give stability to the wind farm. In the lower part, a shaft with a magnetic bearing is installed in the housing and a drive roller of a cylindrical friction gear is installed on it. The driven roller is fixed on the shaft of the electric generator, which is connected through a rectifier to the battery and the load. The slots for fastening the blades with locks are located along the entire shaft at different levels, guides of the blades are inserted into them, on which the soft material of the blade is wound, depending on the required length and distance between the mounting slots.

EFFECT: providing the ability to change the number of blades, their area and their location on a vertical shaft to improve the efficiency of wind energy conversion and reduce friction losses, avoiding the need for lubricants in low temperature conditions.
