RU2571998C2 - Wind electric plant - Google Patents

Abstract

FIELD: power industry.

SUBSTANCE: invention relates to wind power engineering, namely to wind electric plants. A wind electric plant includes a base with two vertical rotors, which rotates in a horizontal plane, a fairing and a stabiliser. The rotary base is provided with a horizontally lying T-shaped post, the cross-beam of which is oriented to the flow, and three vertical guides are installed on the post itself. Two vertical guides are located between vertical rotors. The third vertical guide is located on the end face of the post. The first vertical guide is provided with a horizontal cross-beam that is parallel to the cross-beam of the T-shaped post. A fairing bed is stretched between the horizontal cross-beams. A stabiliser bed is stretched between the second and the third vertical guides.

EFFECT: invention is aimed at reduction of weight and dimensions of a wind electric plant.

Description

The invention relates to the field of wind energy, namely to wind power stations.

Known wind turbine [Pat. RF №2358147, publ. 06/10/2009, bull. No. 16, office 2007135964/06, 09/27/2007 / Litvinenko A.M. - Wind turbine], which contains a tower, a rotary device, a supporting structure, installed on it ducts, vertical shafts and rotating in different directions of the wind wheel with blades with a vertical axis of rotation.

The disadvantage of this wind turbine is the bulkiness of the design. This drawback is partially eliminated in the closest analogue.

Of all the known analogues, the closest to the claimed in terms of essential features is a wind power station [Pat. RF №2179261, publ. 06/10/1999, call 97114606/06, 08/13/1997 / Makarov Yu.S. - Wind power station], which contains a housing mounted with the possibility of rotation in the horizontal plane on a support under the pressure of the wind on a stabilizer mounted on the housing.

The disadvantage of this wind farm is its low manufacturability, due to the need to use separate dampers and stabilizers.

The invention is aimed at improving the manufacturability of the device.

This is achieved by the fact that at a wind power station containing a base rotatable in a horizontal plane with two vertical rotors, a radome and a stabilizer, according to the invention, the rotary base is equipped with a horizontally lying T-shaped stand, the crossbar of which is oriented to the flow, and three vertical guides are installed on the stand itself , two of which are located between the vertical rotors, and the third - at the end of the rack, and the first vertical guide, in turn, is provided with horizontal a horizontal bar parallel to the crossbar of the T-shaped strut, while the fairing web is stretched between the horizontal bars and the stabilizer web is stretched between the second and third vertical rails.

The invention is illustrated by drawings, in which Fig. 1 shows a horizontal T-shaped rack, a top view, Fig. 2 is a side view, Fig. 3 is a front view of a wind farm, Fig. 4 is a side view, .

The wind farm contains a horizontally lying T-shaped rack 1, the crossbar 2 of which is oriented to the flow. On the rack itself, there are installed: vertical rails 3 and 4 between the vertical rotors 5 and 6, as well as a rail 7 at the end of the rack, while the first vertical rail 3, in turn, is equipped with a horizontal crossbar 8 parallel to the crossbar 2 of the T-shaped rack, while between rungs 2 and 8 stretched the web 9 of the fairing, and between the second 4 and third 7 vertical guides stretched the web 10 of the stabilizer. The wind power station contains a tower 11 with a rotary base 12, on which a T-shaped rack 2 and generators with shafts 13 are installed, on which rotors 5 and 6 are also installed.

The operation of the device. When the wind flow is on, the rotors 5 and 6 come into rotation, while the orientation to the wind is determined by the rotation of the base 12, on which the rack 1 with stabilizer 10 is mounted. The middle part of the rotors is outside the zone of the wind flow due to the action of the fairing 9.

The technical and economic advantage is the high manufacturability of wind farms, due to the presence of simple elements and typical connections.

Claims (1)

A wind power station containing a horizontal rotary base with two vertical rotors, a fairing and a stabilizer, characterized in that the rotary base is equipped with a horizontally lying T-shaped rack, the crossbar of which is oriented to the flow, and three vertical guides are installed on the rack itself, two of which located between the vertical rotors, and the third - at the end of the rack, and the first vertical guide, in turn, is equipped with a horizontal bar parallel to erekladine T-shaped rack, wherein the horizontal beams spanned between blade shroud and between the second and third vertical guide web tightly stabilizer.
