Abstract

Usage: the invention relates to plants for generating energy using a wind flow. SUBSTANCE: installation includes a vertical tower mounted on a base, inside of which there is a vertical shaft with a gear wheel and a hub with radial traverses mounted on it. In the holes of the traverse, trunnion pins with sprockets are mounted. The shaft is concentrically enclosed by a tubular coupling with a block of sprockets and gears. Each of the sprocket blades and sprockets of the block is pairwise covered by endless chains. The gear alignment device rotates the tubular sleeve with a sprocket block, thereby changing the orientation of the movement of the blades relative to the direction of the wind flow. The wind flow rotates the blades and the shaft, the torque from which through the gears, the gearbox is transmitted to the electric generator. 2 ill.

Description

The invention relates to wind energy and is intended for use in power generation devices using wind flow.,

The purpose of the invention is to simplify the design and increase reliability.

Figure 1 shows the construction of a wind power installation: Figure 2 shows a section along AA.

The wind power installation contains a wind wheel with rotary blades 1 mounted on the ends of the traverse 2 connected to a vertical shaft 3 kinematically connected to the generator 4, the device 5 for the orientation of the blades 1 with the gear 7 fixed to its shaft 6, the Orientation device 5 is equipped with an installed concentrator vertically to the vertical shaft 3 with a tubular coupling 8 with a block of 9 sprockets and gear 10 located respectively in its upper and lower parts, blades 1 with 11 sprockets 12 mounted on their pins, the number of teeth of each cat ryh twice the number of teeth of each of the sprockets 9, clutch unit 8, the latter by means of an endless chain 13 coupled with the respective sprockets 12 of the blades 1: 10 and the gear clutch 8 engages with a pinion shaft 7 6 5 device orientation. In addition to this, oh, the shaft 3 is equipped with a gear wheel 14, and the generator 4 with a gearbox 15.

Installation works as follows.

Orientation device 5 rotates the tubular sleeve 8 with a block 9. of sprockets, which, using chains 13, rotate the blades 1 to their narrow position, in which the movement against the wind flow is performed in the parallel position of the planes of the directed wind flow

ka - with minimal aerodynamic drag. The movement of the blades 1 behind the wind flow is carried out in the perpendicular position of their planes in the direction of the wind flow. Moreover, each of the blades 1, making a complete revolution around its own axis, making a rotation through 180 °, is in each of its positions with a positive angle of attack relative to the direction of the wind and its movement. The pressure of the wind flow on the blades 1 creates a torque of the wind wheel, which is transmitted through the shaft 3, the gear 14 and the gear 15 to the generator 4.
