Claim 0:
1. A wind generator of variable size and power, comprising:
a vertical mast (35) rigidly stabilized on a ground, to a top (36) of which is mounted a rotation element (37), with a frame (2) mounted on the rotation element (37) with a frame (2) lower part (38), such that the rotational element (37) provides axial rotation of the frame (2) in a range from 0° to 360°, wherein,
the frame (2) comprises a three-dimensional truss frame construction (5) with traverses (6), to which at least one rigid closed elliptical base (1) is attached, the at least one elliptical base (1) carrying a guide rail (3) with grooves (4), the guide rail (3) having at least one pair of rollers (9), (10), (11), and (12) installed in the grooves (4), which allows rollers rotation and rolling in the grooves (4) along an entire closed circuit of the elliptical base (1), wherein,
along an entire contour of the elliptical base (1) the blades (16) are radially fixed and arranged in one plane using carriages (7), and each of the blades (16) is made in a shape of an elongated plate having an aerodynamic asymmetrical profile, wherein,
each of the carriages (7) is made of a bracket (39), which is connected to a mounting plate (8) on which installed the at least one pair of rollers (9), (10), (11), and (12), and each of the installed rollers (9), (10), (11), and (12) is capable to rotate around own axis, wherein,
holders (17) of the blades (16) are attached to the brackets (39) of the carriages (7), with the blades (16) attached in turn to the holders (17) by hinge connections (18), which allow changing an angle of inclination of the blades (16) with respect to a plane of the elliptical base (1), wherein,
each of the carriages (7) is connected to neighboring carriages (7) by connecting rails (13) and rods (14), such that all the carriages (7) connected to each other in series, form a chain carriage of the carriages (7) and the connecting rails (13) as a closed circuit (15), wherein,
all the carriages (7) with the attached blades (16) as a part of the closed circuit (15), are installed with their own rollers (9), (10), (11), and (12) in the grooves (4) of the guide (3) elliptical base (1) which allows rotation of the closed circuit (15) with the blades (16) along the closed contour of the elliptical base (1);
a generator block (19), comprising a generator (20) on a shaft (21) of which a main pulley (22) is placed, a tension pulley (23), pressure rollers (24), (25), and a belt (26), wherein,
the generator block (19) is installed on its own mounting rail (27), which is mounted on the elliptical base (1) such that the belt (26) alternately contacts the moving connecting rails (13) of the closed circuit (15) using the pressure rollers (24, 25) during operation of the wind generator, thus allowing to receive/transmit mechanical energy, wherein,
the generator (20) has a connection via a generator controller (41) to a power unit electronics (28), which comprises at least a power converter (29) of the controller generator (41) and ballast resistance (30);
a control electronics unit (31) based on a rotary controller (32), and a wind speed sensor (33) and a wind direction sensor (34) for data transmission to the control electronics unit (31), which is configured to transmit control signals to the rotation element (37) to ensure a necessary location of the frame (2) of the wind generator in relation to a wind direction based on obtained data, and for providing a halt of the wind generator when a wind speed exceeds 18 m/s.
