Abstract

The invention makes it possible to increase the utilization of wind energy. Paddle wheels (LC) and guide vanes coaxial to it are placed on the vertical shaft. The NAs are arranged in the order of successive alternation with the LC, their blades have arcuate cross sections that are symmetrical with respect to the LC planes. Each HA is made in the form of a hollow coca 6 with outer 7 guides and 8 inner blades fixed on its surface. The blades have areas adjacent to the LC and bent inward arcs of the cross sections of the blades. The inner vanes 8 are located at the base 10 of the coca 6, the outer vanes 7 are located at its top 11, and the latter are oriented in one direction for all the cocks. Passing the blades of the LC on the windward side, the air flow enters coca 6, where it smoothly turns and falls on the blades from the leeward side. Thus, the air flow is triggered twice on each of the LC, and the wind turbine perceives the wind in any direction. 4 il.

The invention relates to wind power and relates to multi-colored wind turbines with guide vanes.

The purpose of the invention is to increase the utilization of wind energy.

Figure 1 presents a lot of Russian wind turbine, a general view; Fig. 2 shows a paddle wheel; Fig. 3 shows a guide vehicle; Fig. 4 shows the elements of the flow section of a wind turbine.

A multi-colored wind turbine contains impellers 2 fixed on a vertical shaft and guide vanes 3 placed along shaft 1 coaxial to it. The guide vanes 3 are arranged in D order of sequential alternation with the paddle wheels 2, their blades 4 have arcuate cross sections 5, symmetrical with respect to the planes of the wheels 2. Each apparatus 3 is made in the form of a hollow coca 6 with outer guides 7 and internal 8 blades with sections 9, adjacent to the wheels 2 and bent inside arcs of cross-sections 5 blades 4. The internal blades 8 are located at the base 10 of the coca 6, the external blades 7 - at its top 11, and the last x 6 spinners are oriented in one direction. A shaft 13 is connected to shaft 1 by means of a gearbox 12.

In operation, a wind turbine perceives wind in any direction. The air flow, attracted to the wind turbine, is deflected by the blades 7 and their sections 9 directed at the angle of attack "C on the blades of 4 wheels

2. Pass the blades 4 of the wheels 2 on the windward side of the wind turbine, the air flow enters the interior of the cocks 6, where it is smoothly turned and guided by the blades 8 with their sections 9 on the blades 4 of the wheels 2 on the leeward side of the wind turbine. Double acting on each of the impellers 2, the air flow comes from the leeward side of the wind turbine through the diffuser channels formed by the blades 7 and the surfaces of the cocks 6. The rotation of the wheels 2, caused by the interaction of the flow with the blades 4, is transmitted through the shaft 1 and the gearbox 12 to the electric generator 13 .
