Description

(54) Wind turbine

one

The invention relates to the energy sector and can be used in the winds of the rotor engines.

A wind turbine is known, holding the body with a diffuser and mounted in the body of the wind wheel with blades ij.

In a well-known wind turbine, the diffuser does not provide an adequate pressure drop, on which the power and efficiency of the impeller depend.

The purpose of the invention is to increase efficiency by reducing hydraulic losses.

This goal is achieved by the fact that the wind turbine additionally contains two hollow skirts, symmetrically mounted with brackets on the body and having outer and inner walls with slotted holes, forming an annular cavity, and in the latter a cylindrical partition is installed, and in the diffuser - a shell forming there is an annular channel associated with the cavity and having an entrance slit located on the side of the wind wheel.

The drawing depicts the proposed

wind turbine, general view.

The wind turbine includes a housing 1 with a diffuser 2 and a wind wheel 3 with a blade B1 4 installed in (case 1). The wind turbine additionally contains two hollow fairings 5 and b, symmetrically fixed with lm jup brackets 7 on case 1 and having external and internal skgens 8 and 9 with slotted holes J.O., which enclose the annular cavity 11. and in the latter there is a cylindrical partition 12, and in the diffuser 2 there are both 13 and 13 arrays, which form an annular channel 14 connected to the cavity

15 11 and the inlet slot 15 located on the side of the wind wheel 3. In case 1 there is a turbine 16 with blades 17. On case 1 on the opposite side of the diffuser 2

The air flow, entry into the configuration 18, gets fixed vanes 19, which twist the air flow and provide a preload of the flow to the blades of the m 17 turbine 16. When the wind flow contacts the hollow fairings 5 and 6 on their outer

Claims (1)

Claim A wind turbine comprising a casing with a diffuser and a wind wheel with blades installed in the casing, characterized in that, in order to increase efficiency by reducing hydraulic losses, the wind turbine additionally contains two hollow cowls, ⁵ symmetrically mounted with brackets on the casing and having external and internal walls with slit holes forming an annular cavity, the latter having a cylindrical partition, and in the diffuser a shell forming an annular channel connected with the cavity and eyuschy entrance slit, positioned on the part of the propeller.
