WIND TURBINE

Abstract

The utility model relates to alternative energy. The present wind turbine includes a symmetrical housing, which tapers from a lower part to an upper part and has a hemispherical fairing mounted thereabove, and lateral ribs which are vertically fastened on the housing and on which is fastened an annular fairing with a convex outer surface, a multi-bladed wind impeller being rigidly fastened inside of said annular fairing on a vertical electric generator shaft, wherein the hemispherical fairing has an aerodynamic annular baffle fastened in the lower part thereof, and the hemispherical fairing is configured to have a diameter greater than the diameter of the annular fairing with a convex outer surface. The utility model is aimed at increasing the speed of an air stream passing through the plane of rotation of a wind impeller while simultaneously preventing meteorological precipitation and foreign objects from entering the plane of rotation of the wind impeller.

Description

[0007] The utility model is described in more detail by example and is accompanied by corresponding drawings, in which:

[0008] FIG. 1 is a general side view of a wind turbine;

[0009] FIG. 2 is a cross-sectional side view of a wind turbine and the basic design of an annular aerodynamic baffle;

[0010] FIG. 3 is a schematic diagram of the movement of air masses relative to a working wind turbine;

[0011] FIG. 4 is a schematic diagram of the operation of a wind turbine under adverse weather conditions.

[0012] The wind turbine (FIG. 1) consists of a body 1, tapering from the lower part to the upper part, installed on a shock-absorbing base 2. On the body 1 are vertically fastened lateral surface ribs 3, which together with the tapering body 1 act as an open flow passage for the oncoming air flow. The lateral ribs 3 in the upper part of the body 1 abut an annular fairing 4 with a convex outer surface, on the struts 5 of which a hemispherical fairing 6 is fastened, in the upper convex part of which a vacuum is created when exposed to the wind and which has an aerodynamic annular baffle 7 in its lower part. The diameter of the hemispherical fairing 6 with the aerodynamic baffle 7 exceeds the diameter of the annular fairing 4 with a convex outer surface. On the inner side of the annular fairing 4 with a convex outer surface, on the base 1 is rigidly fastened a stationary guide device 8, above which a multi-blade wind impeller 9 is fastened in the immediate vicinity, rigidly installed on the vertical shaft of the electric generator 10, which is electrically connected to the storage battery 11. On the wind impeller 9 is fastened a spherical fairing 12 that rotates together with the wind impeller 9.

[0013] The wind turbine works as follows. In the presence of wind, regardless of its direction, air masses having excess pressure from the kinetic energy of the wind move to the region of reduced pressure on the hemispherical fairing 6 and on the annular aerodynamic baffle 7 along the tapering symmetrical body 1 down the vertical ribs 3 to the fixed blades 8 of the guide device. In the guide blades 8 the air flow is deflected at an optimal angle, which is in the range from 15° to 20°, and at this angle it passes through the blades of the multi-blade wind impeller 9, creating aerodynamic forces directed toward the rotation of the wind impeller 9.

[0014] The wind impeller 9 is rigidly fastened to the shaft of the electric generator 10, which as it rotates generates electricity, accumulating it in the storage battery 11 for further transmission to consumers. Having passed through the plane of rotation of the wind impeller 9, the air masses continue to move into the area of reduced pressure formed from the wind on the upper part of the hemispherical fairing 6 and on the outer side surface of the annular aerodynamic baffle 7 (FIG. 3).

[0015] The outer surfaces of the hemispherical fairing 6, the annular fairing 4 with a convex outer surface, and the body 1 are covered with sun-absorbing elements that make it possible to generate electricity from solar radiation regardless of the wind speed or in its absence.

[0016] The hemispherical fairing 6 with an aerodynamic baffle 7, an annular fairing 4 with a convex outer surface, lateral ribs, and a tapering body assure an increase in the speed of the air flow passing through the plane of the wind impeller of a wind turbine even in emergency situations: in the event of a hurricane, storm winds, i.e. when the wind speed exceeds 30 m/s, and given the presence of foreign objects in the air (FIG. 4).
