Description

The present invention relates to the field of energy and, in particular, can be used in wind energy to produce electrical energy by converting the force of the air flow into electrical energy, as well as in river and brook power plants.

The known problem of damping the speed of rotation of the impeller of a wind generator when exposed to a wind stream on the impeller blades running onto the wind stream. This significantly reduces the efficiency of the wind generator.

Known wind generator containing radially placed in the vertical plane of the partition, forming channels in which the wind generators are made, made in the form of a tubular stand, supporting elements, with the possibility of axial rotation, and wind wheels rigidly fixed in the radial direction, each of which is made in the form of fixed with supporting elements of two frames and plates located with them in the same plane, having the possibility of one-way rotation in a vertical plane, and the plates are placed on one half of the wheel with the leeward, and on the other with the leeward side of the air flow, the frame of the wind wheels located on the periphery of the device, see RU 93014714, H02N 1/00 of 03/22/1993.

A wind generator wind turbine is known, containing a conical body with spiral blades twisted around the axis of rotation, see UA 102689 Onipko Rotor, F03D 1/06, F03B 3/12, B64C 11/00, B63H 1/14 from 15.11. 2010, selected as a prototype.

A disadvantage of the known wind generator is its low efficiency, due to the decrease in the speed of rotation of the wind wheel due to crushing and scattering of the wind flow and its loss on its horizontal mounting system, see the journal "Inventor and Rationalizer", 12, 2013, p. 12, and also possible accident rate due to the high probability of destruction of the blades at high speed rotation.

The aim of the creation of the present invention is to achieve a technical result to improve the efficiency of use of the wind flow and the elimination of a possible accident when the destruction of the wind wheel.

The specified technical result is achieved by the fact that in the known wind turbine of the wind generator, containing, for example, a clockwise-rotating impeller with blades mounted on a vertical axis of rotation, it is proposed to introduce a cylindrical body, the rear side of which is open and the front side facing the wind flow, the side is proposed to be divided into two equal parts, the part covering the blades of the wind wheel running towards the wind flow is made in the form of a triangular prism, the height of which it must be equal to the height of the casing, it is proposed to perform one side of the triangular prism combined with a part of the front side of the casing covering the blades running on the wind flow, the second side of the triangular prism is proposed to be made in the form of a flat plate adjacent to the surface of the cylindrical casing and directed towards the air vector flow, the third side of the prism is proposed to perform in the form of a flat or concave plate, one edge of which is connected to the protruding edge of the second side of the a coal prism, and the other edge of the plate to be adjacent to the nearest edge of the open part of the cylindrical body, it is proposed to install a weather vane on the upper base of the cylindrical body, to make the impeller from the triangular prisms forming the cylinder connected by the sides, and to establish plate blades between the adjacent sides of the composite triangular prisms.

The invention is illustrated in graphic materials. In FIG. 1 shows the general construction of a wind wheel; FIG. 2 shows a simplified design of an impeller assembled from composed triangular prisms with blades.

In FIG. 1 shows a wind wheel of a wind generator, on which are reflected:

1 - wind wheel housing;

2 - impeller;

3 - the back side of the housing;

4 - front side of the housing;

5 - wind flow;

6 - triangular prism;

7 - weather vane;

8 - impeller blades;

9 - composite triangular prisms;

10 - the second side of the triangular prism;

11 - the third side of the triangular prism.

The wind generator wind turbine contains an impeller 2 with blades, closed by a cylindrical housing 1. The rear side 3 of the housing 1 is open, its front side 4, facing the wind flow 5, is divided into two equal parts. The part of the front side 5 covering the impeller 2, the blades of which rotate towards the incoming wind stream 5, is made in the form of a triangular prism 6, the height of which is equal to the height of the housing 1. One side face of the triangular prism 6 is a common side of that part of the front side of the housing that covers the blades 8, running onto the wind stream 5, the second side 10 of the triangular prism 6 is made in the form of a flat plate tangentially adjacent to the surface of the cylindrical body 1 and directed towards the air flow vector 5 , the third side 11 of the triangular prism 6 is made in the form of a flat or concave plate, one edge of which is connected to the protruding edge of the second side 10 of the triangular prism 6, and its other edge is connected to the nearest edge of the open part of the housing 1. A weather vane is installed on the upper base of the cylindrical housing 1 7, while the impeller 2 is made of composite triangular prisms 9 connected by the sides and forming a cylinder; lamellar blades 6 are installed between their adjacent sides.

The wind wheel works as follows.

The air flow 5, running onto the wind turbine casing 1, orientes it by means of a weather vane 7 so that the casing 1 turns with its front part exactly in line with the wind flow 5. In this case, part of the wind flow 5 freely passes through the open part of the front side 4 of the wind turbine casing 1 and freely exits through the rear side 3 of the housing 1, causing the impeller 2 to rotate. Part of the wind flow 5 directed to the closed part of the front side of the housing 1, when in contact with the housing 1, abuts a third or a concave plate First side 11 of the triangular prism 6 and slides in the open part of the front side 4 of the housing 1, further increasing pressure on the impeller blade 2 and increasing the rotational speed of the propeller.

Depending on the wind rose in the area where the wind generator is used to eliminate the possibility of destruction of the wind wheel, the number of composite triangular prisms 9, and hence the number of blades 6 can be changed.

The present invention, in addition to the use in the conversion of wind energy into electricity, can be used as a mover in brook and river power plants.

The present invention is new and has never been used before, which indicates its compliance with the patentability criterion of novelty.

The claimed wind wheel can be made in any workshop from improvised materials using improvised means, which indicates its compliance with the patentability criterion of industrial applicability.
