The utility model refers to a wind power plant with a rotatable for adaptation to the wind direction substructure on which at least one coupled with an output wind rotor is arranged.

The utility model is the object of the invention to provide a wind power plant of this type, which has a fundamentally simple structure, at the same time allows for a particularly high degree of utilization of \\ _ Lndkraft at low and medium wind strength and a strong reduction of the load at greater wind strength.

This object is achieved according to the innovation that the wind rotor has a plurality of blade groups attached to a common shaft. and that wind deflecting surfaces are provided with a straight edge running in the vicinity of the impeller periphery axially parallel to the wind rotor, which catch the incoming wind, accelerate the wind flow and feed them to the impellers to be impinged on one side of the rotor shaft and those on the other side Shielding the rotor shaft located blades against the influx of wind. The provided at the border between the mentioned two sections straight edge may also be rounded. Each of the groups of blades fastened on a common shaft can, for example, be four at an angular distance of 90 °.

be present. In order to stiffen the individual blade groups or wheels in itself, it is recommended that

The blade ends of each blade group are braced against one another by connecting links in the form of rods or flexible strands arranged in the manner of the bowstrings of the blade wheel. The wind deflecting surfaces

Canvas windscreens may be reefable by being guided with rings between parallel support rods so that they can be pushed together to one side. As a result, a considerable relief in very strong wind can be achieved.

In the following the innovation with reference to the drawings, in which two embodiments are shown, explained in more detail. Show it

Fig. 1 shows schematically the structure of a preferred in.: Guidance of the wind rotor 1. On a common shaft 2 five blade groups or paddle wheels 3, 4, 5, 6, 7 are fixed in this case. Each blade blade comprises four blades 6 arranged at an angular distance of 90 °. Each two adjacent blade groups are on the shaft 2 by a half. Angular distance of the one blades 6 arranged offset from one another.

The two exemplary embodiments of the wind power plant according to the invention, which are shown schematically in FIGS. 2 to h and 5 and 6, each have a substructure 10 which is rotatable to adapt to the wind direction, consisting of a base plate 11 resting on the ground and an active part disposed above it the wind turbine supporting urehsockel 12, the like in on circular rails or the like. guided rollers, balls or other rolling elements 13 is mounted.

In the first embodiment illustrated in FIGS. 2, 3 and 4, the wind rotor 1 is arranged horizontally. In the interest of clarity of the drawing, only the blades 6 of the foremost blade group of the wind rotor are shown in FIG. The wind rotor is between wind deflecting surfaces 20, 21, 20 ', 21¹ arranged. By the wind deflecting surfaces 20, 20 ', the wind flowing in the direction of the arrow (FIG. 4) is collected, the wind flow is accelerated and fed to the blades 6 on the upper half of the wind rotor s 1. The blades located on the lower half of the rotor 1 are shielded against the influx of the wind by a ramp, which has a straight edge 23 running parallel to the axis of the wind rotor. The ramp 22 may be adjustable as indicated by the dashed line 22 'to suit the wind conditions. The wind rotor 1 is mounted on brackets 2k, 24 '. In Fig. 3, which shows a sectional view looking towards the sectional plane III-II1 of Fig. 2, the wind catcher surfaces 20, 20 'indicated by dash-dotted lines. The wind catcher or -lenkflächen are arranged substantially vertically standing on the rotary base 12. In Fig. 4 the rotary base is indicated as a broken section.

In the second embodiment according to FIGS. 5 and 6, two wind rotors 1, 1 'arranged side by side with a vertical axis are provided.

The Windötrömungsrichtung is indicated in Fig. 6 by arrows. On the upstream side of the wind rotors I₃ I¹ are at an angle symmetrical to the indicated by a dotted line 30 vertical center plane of the incoming wind substantially perpendicular to the base plate 12 wind catcher surfaces 31, 31 'arranged on each of a vertical edge 32, 32' in the vicinity of the circumference of each of the Wind rotors 1, 1 'in a curved, a part of the circumference of the two wind rotors at a small distance enclosing Schirmflächenabschnittt 33, 33' merge. Between the two wind catcher surfaces 31, 31 'are also at an angle symmetrical to the vertical center plane 30 additional V / indleitebene ~ $ k, 3 * J' arranged. Furthermore, on the outflow side of the two wind rotors symmetrically to the vertical center plane 30 in plan V-shaped Abwindlenkflächen 35, 35 'are provided.

For the sake of clarity, a wind rotor 1 'and the wind deflecting surfaces 31', 33 ', 3' are omitted in FIG. 5 and indicated only by their feet or foot lines.

However, the arrangement of the wind deflecting surfaces also makes it possible, especially in the case of training as canvas surfaces, to relieve the canvas by reefing at high wind strength, for example by pushing back the cloth held on horizontal bars rings. A wind turbine corresponding to the new mg is suitable not only for installation on solid ground but also for use on vehicles, for example on ships.

An important possibility for the further development of the innovation is that the blades are arranged at a distance from the wind rotor shaft carrying them and connected thereto by support rods.
