INVENTION
Russian Federation Patent RU2293211
ROTOR wind turbine
Name of the inventor: Dyadchenko Nikolai
The name of the patentee: Nikolai Dyadchenko
Address for correspondence: 600000, Vladimir, ul. Podbelskogo, 2, Post Office, NP Dyadchenko (demand)
Starting date of the patent: 2005.06.23
The invention relates to the field of wind energy. The technical result consists in increasing the use efficiency of the wind flow in the rotors oriented vertically at moderate wind speeds, is achieved by the fact that in the rotor of a wind turbine comprising a vertical shaft with blades on its outer surface, wherein the blades are made with an increasing radial dimension in height rotor blades of the rotor according to the invention installed in spirals so that the end of each subsequent blade in an upper layer overlaps the beginning of the preceding rotor blade of the rotor on the lower level.
DESCRIPTION OF THE INVENTION
The invention relates to wind energy and can be used for the stable operation of wind turbines at moderate wind speeds.
Known rotor of wind turbine comprising a vertical shaft with blades on its outer surface, wherein the blades are made with increasing size of the radial height of the rotor (see. JP, 10274148 A, cl. F 03 D 3/06, 13.10.1998, 6). , the essential features adopted for the closest analogue of the invention (prototype).
rotor disadvantages are its low efficiency at moderate wind speeds and low efficiency (efficiency).
The technical result consists in increasing the use efficiency of the wind flow in the rotors oriented vertically at moderate wind speeds, is achieved by the fact that in the rotor of a wind turbine comprising a vertical shaft with blades on its outer surface, wherein the blades are made with an increasing radial dimension in height rotor blades of the rotor according to the invention installed in spirals so that the end of each subsequent blade in an upper layer overlaps the beginning of the preceding rotor blade of the rotor on the lower level. The outer surface of the rotor shaft has a cylindrical or conical shape with the apex of the cone located on the lower level of the rotor.

1 shows a wind turbine rotor, general view; Figure 2 - a rotor of a wind turbine, view from above. A wind turbine rotor comprises a vertical shaft (e.g., execution of triple tube) with the blades on the outer surface of the shaft. Blades (which may be composite) are adapted for increasing the radial size of the rotor height in spirals so that the end of each subsequent blade in an upper layer overlaps the beginning of the preceding rotor blade of the rotor on the lower level. The outer surface of the rotor shaft has a cylindrical or conical shape with the apex of the cone located on the lower level of the rotor. |
ROTOR wind turbine works as follows
wind stream hitting the blade in the rotor, appropriately oriented to the incident flow, transmits its kinetic energy to the blades, thereby causing the turbine to rotate the rotor and shaft (or shafts) to which (or whom) the blades are attached. In addition, inside the rotor cone formed swirling flow of the wind, which according to the law of continuity of flow increases the total kinetic energy, but also the power and efficiency of the rotor. The rotation of the rotor shaft of a wind turbine contributes to the generator shaft rotation (not shown), and generates the final result of the electric energy is transmitted to consumers.
CLAIM
1. The wind turbine rotor comprising a vertical shaft with blades on its outer surface, wherein the blades are made with increasing size of the radial height of the rotor, wherein the rotor blades are mounted in spirals so that the end of each subsequent blade in an upper layer overlaps the beginning of the previous rotor blade at the lower level of the rotor.
2. Rotor according to claim 1, characterized in that the outer surface of the rotor shaft has a cylindrical or conical shape with the apex of the cone located on the lower level of the rotor.
