| 1. | The wind power plant equipped with a turbine wheel swivelmounted on the mast, distinguished by turbine wheel (1) having two concentric rings: outer ring (2) and inner ring (3), with profiled drive wings (4) being spanned between them. |
| 2. | The wind power plant according to Provision 1 above, distinguished by drive wings (4) filling 3/5 of the space contained between outer ring (2) and inner ring (3). |
| 3. | The wind power plant according to Provision 1 above, distinguished by drive wings (4) having an arc profile and a trapezoid shape with the width being greater on the side of outer ring (2) and smaller on the side of inner ring (3). |
| 4. | The wind power plant according to Provision 1 above, distinguished by the diameter of inner ring (3) being 2/5 of the diameter of outer ring (2). |
| 5. | The wind power plant according to Provision 1 above, distinguished by the arithmetic mean of the width dimension of each drive wing (4) being from 20 mm to 100 mm. |
Known from Polish Patent Specification No. 176172, the wind power plant is composed of a mast-mounted horizontal-axle rotor equipped with radially-mounted wings, whose shaft is connected via a mechanical transmission with a mast- mounted vertical shaft, with which a current generator is mechanically coupled.
Radially arranged rotor wings are positioned between two ring sets, of which the aerial set fixed permanently to the rotor shaft is composed of at least two permanently fixed concentric ring connectors, to which wings are swivel-mounted by the edges of attack.
The purpose of the invention is to develop such a power plant design, which will enable the most effective use of wind power.
According to this invention, the turbine wheel has two cylindrical rings: an outer ring and an inner ring, between which profiled drive wings are spanned. The drive wings occupy 3/5 of the space contained between the outer ring and the inner ring.
The drive wheels have an arc profile and a trapezoid shape with the width being greater on the outer ring side and smaller on the inner ring side.
The diameter of the inner ring preferably constitutes 2/5 of the outer ring diameter, and the arithmetic mean of the width dimension of each drive wing is preferably from 20 mm to 100 mm.
The design of the wind power plant according to this invention enables the most effective use of the power of wind, especially of a velocity of 2 m/s and above.
The subject of this invention is illustrated in the example of execution on the drawing, where Fig. 1 shows the wind power plant as seen from the wind blow side, while Fig. 2 shows the cross-section of a drive wing.
Turbine wheel (1) has two concentric rings: outer ring (2) and inner ring (3), between which profiled drive wings (4) are spanned. Drive wings (4) occupy 3/5 of the space contained between outer ring (2) and inner ring (3). Drive wings have an arc profile and a trapezoid shape with the width being greater on the side of outer ring (2) and smaller on the side of inner ring (3). The diameter of inner ring (3) makes up 2/5 of the diameter of outer ring (2). The arithmetic mean of the width dimension of each drive wing (4) is from 20 mm to 100 mm.
