LOW-POWER PADDLE-TYPE WIND-DRIVEN ELECTRIC PLANT Russian patent published in 2004 - IPC

FIELD: wind-power engineering.

SUBSTANCE: invention relates to paddle-type wind-driven motors designed for generating heat and electric energy to satisfy power demands of consumers at farms. Proposed wind-driven electric plant contains inlet contraction and windwheel, guide-vane assembly with smooth conical surface installed in contraction before windwheel and rigidly connected with wind motor shaft, device converting mechanical energy of shaft rotation into electric energy, device for orientating windwheel to wind, rotary head and mast. Plant is furnished additional with second coaxial windwheel of the same diameter nut with smaller number of blades, both windwheels are rigidly connected with wind motor shaft and are arranged in cylindrical turbine compartment to front end of which intake contraction is connected, and to rear end, rejector is attached. Windwheel with larger number of blades is located from side of intake contraction, and summary area of outlet holes of rejector exceeds area of hole of intake contraction. Spoilers can be installed before outlet holes of rejector to increase rarefaction in rejector.

EFFECT: accelerated oncoming air flow, increased efficiency of utilization of wind energy, simplified design, reduced overall dimensions and weight, increased service life-plant.
