Wind energy converter with buoyancy elements on a closed Orbit

The most popular types of wind energy converters are in the work of Albert Betz in the "Introduction to the theory of fluid flow machines" as well as in the article "The windmills in the light of recent research" and described by Wilhelm von Heys in "Wind und Windkraftanlagen".

Most of the designs known up to now are propeller-like wind energy converters from the old slow runners to the new fast runners their common feature is that the buoyancy elements are in circular orbits and rotate around a horizontal or vertical axis. The latter on the E.g. Darrieus principle built, need a start-up aid and are only for wind speeds of more than 5 m / sec. suitable. The starting moment (from retirement) of the classic Fast runner is low and can only be achieved through complicated adjustment mechanisms Wings can be partially improved, because the faster the propeller is, the smaller the wing area can be used. It is also known that approx. 0.3 of the propeller diameter - on the axis - has almost no effect is.

It is the object of the present invention to remedy this deficiency.

According to the invention, it is achieved by the feature

times of claim 1.

It is intended for small outputs on the shaft and has the following advantages:

1. It can achieve significantly higher speeds at even medium speeds Achieve faster speed than with the classic high-speed runners .is possible.

2. More favorable starting torque even at lower wind speeds less than 5 m / sec.

3. You can use the same components - buoyancy elements ■ Wind energy converter: build for different capacities, since the number of buoyancy elements and their spacing can be selected »

4. It will be the good aerodynamic properties of the double wing (Double decker) exploited and so the diameter of the engine kept small.

The attached drawings show:

Fig. 3. - The floor plan

According to the invention are located on the carrier 1, which can be constructed vertically or horizontally (not shown) can have two bearing blocks 2, 3 with shafts 4, 5.

On each shaft there is a wheel 6, 7 “Am

The example shown are simple chain wheels that are connected by the chain 8. At certain regular intervals the wing carriers 9 are attached to the chain 8. At Each wing carrier 9 has two wings 10, 11 which together form a double wing. The wind speed

the rotational speed 13 and the resulting outflow speed 14 are indicated.

One of the shafts (in the example the shaft 4) is extended on the opposite wheel side of the bearing block 2 and is used for Decrease in generated power. From there are the not indicated generators, alternators, pumps, compressors etc. driven.

The adjustment of the motor in the required wind direction is done by the rotatable about its longitudinal axis Carrier 1 reaches and happens either through a wind vane, as with the older types of wind motors where the wind turbine is from the vertical axis of rotation - seen in the direction of the wind - or by the fact that the rotating surface of the blades, as in Fig. 2 is shown behind the carrier 1, as is common with modern high-speed runners.

Thin, curved plates are used as wings 10, 11, which are almost insensitive to the changing R number and are easy to manufacture.

If the wind blows against the shown wind motor in the wind direction shown in FIG. 2, the result is conditional through the angle of attack of the wings 10, 11 a lift and thereby a revolving movement of the chain 8, as shown in FIG Is indicated by arrows.
