A rotor of Savonius type, with vertical axis of rotation, in which:1) vertical surface of blade is formed by generatrix that is parallel to axis of rotor rotation and begins near axis of rotor rotation to which it can be tangent over its whole length, after that it is developed in such way that at projection to horizontal intersecting at right angle axis of rotor surface an involute is formed, with evolute for it being circle;2) number of working blades on the rotor shaft is two and more;3) the rotor shaft is mechanically connected to the shaft of electric generator;a) over rotor working zone of deflector is placed, its axis coincides with vertical axis of rotor rotation effect of which is based on use of wind velocity that in its turn forms rarefaction downstream of deflector that provides exchange of air and draught in rotor working zone;b) lower edge of rotor blade at rotation describes convex upwards conical surface axis of which coincides with rotor axis, the top of conical surface is placed on axis of rotor rotation, and base of conical surface is normal to axis of rotor rotation;c) conical surface directs falling working flow in vertical direction;d) generatrix of the cone intersects vertical axis at angle that provides self-discharge of dust deposits and atmospheric precipitations in winter. |
