INVENTION
Russian Federation Patent RU2281410
CAROUSEL wind turbine Ishmuratova
Name of the inventor: Ishmuratov Bilal Hantimirovich (RU); Ishmuratov Marat Bilalovich
The name of the patentee: Ishmuratov Bilal Hantimirovich (RU); Ishmuratov Marat Bilalovich
Address for correspondence: 109383, Moscow, ul. Highway, 51, kv.49, BH Ishmuratov
Starting date of the patent: 2005.01.28
The invention relates to wind energy and wind turbines concerns with fixed vetropriemnikami. The technical result consists in simplifying the construction and improving reliability in operation, ensured by the fact that the carousel wind turbine comprising a vertical shaft and radial blades, according to the invention the radial blades are formed as V-shaped or rounded troughs reinforced stiffening ribs, and is rigidly attached on the horizontal frames, and rigidly fixed on a vertical shaft.
DESCRIPTION OF THE INVENTION
The invention relates to wind energy and wind turbines regard carousel with fixed vetropriemnikami.
Known wind turbine boring (see. SU 1537885, F 03 D 3/00, Bul. № 25, 1990), comprising a vertical shaft and radial cavities, each of which is formed as a frame attached to the shaft mounted therein and a pivoting of the vane operating position parallel plates having bent edge at an acute angle remote from the shaft.
The disadvantage is the design complexity and unreliability in operation.
Known wind turbine boring (see. SU 1787209A3, cl. F 03 D 3/00, 07.01.1993), the essential features taken as the nearest analogue of the invention (prototype) containing a vertical shaft and radial blades, each of which is attached a to the frame and shaft mounted therein rotatably parallel plates consisting of polymer composite material with oriented fibers and fixed in the upper side of the cell.
The disadvantage is the complexity of the design and, as a result, unreliable in operation under changing climatic conditions.
The technical result consists in simplifying the construction and improving reliability in operation, ensured by the fact that the carousel wind turbine comprising a vertical shaft and radial blades, according to the invention the radial blades are formed as V-shaped or rounded troughs reinforced stiffening ribs, and is rigidly attached on the horizontal frames, and rigidly fixed on a vertical shaft. Moreover, the number of V-shaped or rounded troughs on a level greater than or equal to two, and the number of levels is greater than themselves.
The drawing shows a carousel wind turbine, the general form (version with V-shaped grooves).
 |
The rotor wind turbine consists of a vertical shaft 1 with a rigidly attached thereto, at least two horizontal frames and 2 fixed rigidly to their V-shaped or rounded grooves 3, 4 reinforced webbing. Wind turbine powered by wind in any direction. The action of the dynamic pressure of the wind on the chute, which is currently oriented to the wind side, the opposite edge of the V-shaped grooves (drawing right), created the force is much greater than the pressure of the wind on the opposite chute, oriented at the same time streamline the ribbed side . This force causes the rotating shaft 1 (in this example counterclockwise). |
The number of frames with two V-shaped or rounded troughs 3 at the same level can be 2, 3, 4, etc., such as vertical can be multiple levels (in one and the same shaft), the presence of stiffeners on both the ends of the gutters required.
The originality of technical solutions is that the implementation of the working blades V-shaped or round-shaped and rigid mount them on frames and the shaft ensures high reliability under all the pressure of the wind and any climatic conditions.
CLAIM
1. Carousel wind turbine comprising a vertical shaft and radial blades characterized in that the radial blades are formed as V-shaped or rounded troughs reinforced stiffening ribs and is rigidly attached to the horizontal frames, and rigidly fixed on a vertical shaft.
2. Wind turbine according to claim 1, characterized in that the number of V-shaped or rounded troughs on a level greater than or equal to two, and the number of levels is greater than themselves.
