MOBILE WIND POWER PLANT WITH A VERTICAL AXIS OF ROTATION Russian patent published in 2021 - IPC F03D3/00 F03D9/32 F03D13/20 

FIELD: power industry.

SUBSTANCE: mobile wind power plant with a vertical axis of rotation is designed to convert the kinetic energy of air flows at low speeds into electricity for supplying enterprises mainly of agriculture and small businesses located in hard-to-reach and remote areas. The installation contains a hexagonal wind wheel with blades connected to a pipe-mast passing into a closed volume, in which a gearbox is located, connected by couplings to a shaft and a generator connected to a network of electricity consumers. The wind wheel is formed by a hub, closed from above by a hood, with two flanges, to which six spokes of a frame structure made of pipes are rigidly attached, each of which is made of three identical sections. A rim of twelve pipes is rigidly attached to the edges of the spokes. In the extreme sections of the spokes towards the rim, six flat blades in the form of hollow half-cylinders are rigidly fixed. The hub is installed with the possibility of rotation and is connected motionlessly by its top to the shaft located inside the composite pipe-mast in height. In this case, the pipe-mast is installed resting on a U-shaped element with bevel gears, designed to transmit rotation through the first clutch to the gearbox, and through the second clutch to the generator, and is equipped with a flat hinge placed above the closed volume to ensure rotation and lifting of the assembled wind wheel to a vertical position. The installation is movable and equipped with a pipe for lifting a wind wheel with blades to a vertical position, and in the upper part of the pipe there is a rotatable block with a cable, one end connected to an eye attached to the pipe-mast, and the other end connected to a winch fixed in the ground. Below the eyelet of the pipe-mast, cable supports are fixed, connected to anchors fixed in the ground.

EFFECT: ensuring the movement of the installation for operation in the air flow with a reduced complexity of manufacturing.
