BeschreibungDescription

Die Erfindung bezieht sich auf eine Windkraftanlage mit vertikaler Achse, dadurch gekennzeichnet, daß sich auf dem Turm (2) um die Achse (3) nach außen hin, Rotorschaufeln befinden (FIG.1).The invention relates to a wind turbine with a vertical axis, characterized in that rotor blades are located on the tower (2) around the axis (3) towards the outside (FIG.1).

Die Rotorschaufeln sind so angeordnet, daß sie winddurchlässig sind (FIG.2).The rotor blades are arranged so that they are permeable to wind (FIG.2).

Die trichterformähnliche Schaufel ist so angeordnet, daß die hintere öffnung (B) in Windrichtung, ca. 1/3. bis 1/2 der vorderen öffnung (A) betragt ( Stellung FIG.1 Pos. I ).The funnel-shaped blade is arranged so that the rear opening (B) in the wind direction is approximately 1/3 to 1/2 of the front opening (A) (position FIG.1 Pos. I).

Es wird die erfrgiereiche Luftströmung stark abgebremst, jedoch der Luftstau vermieden. Dieser Wind-Bremseffekt bedeutet hier ein hohes Drehmoment. Es wird noch verstärkt durch die an der Innenseite der Schaufel befindlichen unbeweglichen Bremsblätter ( FIG.2, Pos. 1.2 ). Auch hier beträgt der Abstand C : D - ca. 3 : 1 bis 2:1.The fertile air flow is slowed down considerably, but air congestion is avoided. This wind braking effect means a high torque. It is further increased by the immobile brake blades on the inside of the blade ( FIG.2, item 1.2 ). Here too, the distance C:D is approximately 3:1 to 2:1.

Die so erreichte starke Ausnutzung von strömender Windenergie erbringt das hohe Drehmoment d.h. hohe Leistung..The strong utilization of flowing wind energy achieved in this way produces high torque, i.e. high power.

Vergleichsweise arbeitet der bekannte Savonius-Rotor in gleicher Stellung, lediglich mit einem kurzen Luftstau.In comparison, the well-known Savonius rotor works in the same position, only with a short air jam .

In Stellung gegen den Wind ( FIG1 PosIII ) wird die Windanlage relativ wenig abgebremst, da durch die jetzt vordere Öffnung (B) im Schaufelinnern, ein Vacuum nahezu vermieden wird.In the position against the wind ( FIG1 PosIII ) the wind turbine is braked relatively little, since a vacuum is almost avoided due to the now front opening (B) in the interior of the blade.

Die aerodynamisch günstige Stellung und Form der Seitenwände (1.1) sorgen für ein leichtes Vorbeigleiten des Windes.The aerodynamically favourable position and shape of the side walls (1.1) ensure that the wind glides past easily.

Die trichterformähnliche Schaufel ist in etwa 90° (flCf) zum RadiusThe funnel-shaped blade is approximately 90° (flCf) to the radius

angeordnet. Die Seitenwand (1.1) ist auf etwa 50° zum Radius abgewinkelt^^/. Ab Punkt Y ist die Seitenwand um etwa 20° nach innen abgeknickt oder abgebogen Ctx).The side wall (1.1) is angled at about 50° to the radius^^/. From point Y the side wall is bent or curved inwards by about 20° Ct x ).

Innerhalb der Schaufel befinden sich ein oder mehrere Bremsblätter (1.2), die gegenüber der Lage der Seitenwand um etwa 90°abgewinkeit sindC<kz). Diese Bremsblätter sind zu der größeren Öffnung (A) hin, leicht abgebogen oder abgeknickt.Inside the blade there are one or more brake blades (1.2) which are angled by about 90° relative to the position of the side wall (C<kz). These brake blades are slightly bent or kinked towards the larger opening (A).

Außer der Rotorachse (3) und der Elektrostation (4) oder evtl. einer mechanischen Pumoe o.Ä. befinden sich keine beweglichen Teile an der Windkraftanlage.Apart from the rotor axis (3) and the electrical station (4) or possibly a mechanical pump or similar, there are no moving parts on the wind turbine.

Das bedeutet, daß die WKA nahezu wartungsfrei arbeitet und in extrem kalten und warmen Gegenden eingesetzt werden kann.This means that the wind turbine is almost maintenance-free and can be used in extremely cold and warm areas.

Etwa bei Punkt Z (FIG2) liegt die Umfangsgeschwindigkeit des Rotors. Diese Umfangsgeschwindigkeit ist wegen vorhandener Energieverluste immer niedriger als die Windgeschwindigkeit; daher kann diese als "Langsamläufer" zu bezeichnende Windanlage nicht überdrehen. Eine automatische Abbremsvorrichtung, für Sturmstärken, ist daher nicht erforderlich. Ein Nachdrehen in den Wind ist nicht erforderlich, da diese Vertikalanlage, wie bekannt, windrichtungsunabhängig ist.The peripheral speed of the rotor is approximately at point Z (FIG2). This peripheral speed is always lower than the wind speed due to existing energy losses; therefore this wind turbine, which can be described as a "slow-running" turbine, cannot over-rotate. An automatic braking device for storms is therefore not required. Re-rotation into the wind is not necessary because this vertical turbine, as is well known, is independent of the wind direction.

Jede Rotorschaufel ( I-1V ) besteht aus ein oder mehreren Einzelschaufeln ( 1 a - 1d ) die miteinander verbunden sind. Je nach den durchschnittlichen Windverhältnissen am Aufstellungsort ( Starkwind- bis Schwachwindgegenden ) kann die Anzahl der Einzelschaufeln reduziert oder erhöht werden um eine optimale Abstimmung mit dem Generator oder der Pumpe zu ermöglichen.Each rotor blade (I-1V) consists of one or more individual blades (1a - 1d) that are connected to one another. Depending on the average wind conditions at the installation site (strong wind to light wind areas), the number of individual blades can be reduced or increased to enable optimal coordination with the generator or pump.

Aufgrund der einfachen Bauart ist der erfindungsgemäße Rotor mit geringem Aufwand und damit kostengünstig herstellbar.Due to its simple design, the rotor according to the invention can be manufactured with little effort and thus cost-effectively.
