Patent owner's name: Bishal Khantimirovich Ishmuratov (RU); Ishmuratov Marat Bilalovich
Address for correspondence: 109383, Moscow, st. Shosseynaya, 51, ap. 49, B.Kh. Ishmuratov
Starting date of the patent: 2005.01.28

The invention relates to wind energy and relates to wind turbines with rigidly fixed wind receivers. The technical result is to simplify the design and increase reliability during operation, due to the fact that in the rotary wind turbine containing a vertical shaft and radial blades, according to the invention, the radial blades are made in the form of V-shaped or rounded grooves, reinforced ribs and rigidly fixed on horizontal frames, and rigidly mounted on a vertical shaft.

DESCRIPTION OF THE INVENTION

The invention relates to wind energy and relates to carousel wind turbines of the type with rigidly fixed wind receivers.

A carousel wind turbine is known (see SU 1537885, F 03 D 3/00, Bull. No. 25, 1990), which contains a vertical shaft and radial cavities, each of which is made in the form of frames attached to the shaft and installed in it and turning from a wind vane working position parallel plates having a bent sharp angle on the edge remote from the shaft.

The disadvantage is the complexity of the design and unreliability in operation.

Known carousel wind turbine (see SU 1787209A3, CL F 03 D 3/00, 07.01.1993), for the combination of essential features adopted for the closest analogue of the invention (prototype) containing a vertical shaft and radial blades, each of which is made in the form of attached to the shaft of the frame and installed in it with the possibility of rotation of parallel plates consisting of a polymer-composite material with oriented fibers and fixed upper side in the cell.

The disadvantage is the complexity of the design and, as a result, unreliability in operation in changing climatic conditions.

The technical result is to simplify the design and increase reliability during operation, due to the fact that in the rotary wind turbine containing a vertical shaft and radial blades, according to the invention, the radial blades are made in the form of V-shaped or rounded grooves, reinforced ribs and rigidly fixed on horizontal frames, and rigidly mounted on a vertical shaft. Moreover, the number of V-shaped or rounded gutters at one level is greater than or equal to two, and the number of levels themselves is greater than one.

The drawing shows a carousel wind turbine, a general view (option with V-shaped grooves).

Carousel windmill ishmuratovyh

A carousel wind turbine consists of a vertical shaft 1 with at least two horizontal frames 2 rigidly attached to it and 2 V-shaped or rounded grooves 3 fixed to them rigidly and reinforced with stiffening ribs 4.

Wind turbine works from wind of any direction. Under the action of the velocity head of the wind on the chute, which is currently oriented to the wind with the side opposite to the edge of the V-shaped chute (in the drawing is the right part), a force is created that far exceeds the wind pressure on the opposite chute, oriented at the same time by the streamlined ribbed side . This force causes shaft 1 to rotate (in this example, counterclockwise).

The number of frames 2 with V-shaped or rounded grooves 3 at the same level can be 2, 3, 4, etc., and vertically there can be several such levels (on the same shaft), and the presence of stiffeners on both The ends of the gutters are required.

The originality of the technical solution lies in the fact that the implementation of the working blades of V-shaped or rounded shape and their rigid mounting on the frames and on the shaft ensures high reliability at any wind pressure and any climatic conditions.

CLAIM

1. Rotary wind turbine containing a vertical shaft and radial blades, characterized in that the radial blades are made in the form of V-shaped or rounded grooves, reinforced ribs and rigidly mounted on horizontal frames, and rigidly mounted on a vertical shaft.

2. Wind turbine according to claim 1, characterized in that the number of V-shaped or rounded chutes at one level is greater than or equal to two, and the number of levels themselves is greater than one.
