Abstract

Die vorliegende Patentanmeldung betrifft eine Windkraftanlage mit vertikal angeordneter Achse, mit einem um die Achse drehbaren Rotor, der eine Anzahl von achsparallelen geraden oder leicht gebogenen Lamellen (4) aufweist, wobei wenigstens eine Lamelle auf der der Achse zugewandten Seite mit einer Leiste versehen ist, die ebenfalls achsparallel angeordnet ist und von der Oberfläche der wenigstens einen Lamelle absteht.The present patent application relates to a wind power plant with a vertically arranged axis, with a rotor which can be rotated about the axis and which has a number of axially parallel straight or slightly curved blades (4), at least one blade being provided with a strip on the side facing the axis, which is also arranged axially parallel and protrudes from the surface of the at least one lamella.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zur besseren Ausnutzung der Windenergie im Schwachwindbereich für alle Vertikalläufer (Windanlagen mit senkrechter Achse).The invention relates to a device for better utilization of the Wind energy in the low wind range for all vertical runners (wind turbines with vertical axis).

Ähnlich der Landeklappen (bei der Landung) im modernen Flugzeugbau ist auch die hier gezeigte Schwachwindleiste (2) in der Biegung winddurchlässig und sorgt für besonders hohe Auftriebskräfte bei niedriger Windgeschwindig­ keit.Similar to the flaps (when landing) in modern aircraft construction, the low wind bar ( 2 ) shown here is wind-permeable in the bend and ensures particularly high buoyancy forces at low wind speeds.

Fig. I Fig. I

Die Schwachwindleiste ist gekennzeichnet durch eine Leiste die in Längs­ richtung gerade oder leicht gebogen und im Profil abgewinkelt ist. In der Biegung des Profils befinden sich Luftschlitze (7), die dafür sorgen daß der Wind nicht gestaut sondern stark abgebremst, weiter durchströmen kann.The low wind bar is characterized by a bar that is straight or slightly curved in the longitudinal direction and angled in profile. In the bend of the profile there are air slots ( 7 ), which ensure that the wind can flow through, not jammed but strongly braked.

Z. B. erreicht diese Vorrichtung bei den bekannten Rotoren gemäß U.S. Patent 5,044,878 bzw. Euro-Patent 0,317,618 eine enorme Leistungssteigerung d. h. bessere Windenergieausnutzung.For example, in the known rotors according to U.S. Pat. patent 5,044,878 or Euro patent 0,317,618 an enormous increase in performance d. H. better use of wind energy.

Das winkelige Profil ist mit dem kurzen Schenkel am Rotorblatt (1) befestigt. Der lange Schenkel ist gerade oder gebogen angeordnet.The short profile is attached to the rotor blade ( 1 ) by the short leg. The long leg is straight or curved.

Die Form der Platten (3) ist vorzugsweise drei- oder viereckig angeordnet.The shape of the plates ( 3 ) is preferably triangular or quadrangular.

Fig. II Fig. II

Der Rotor, besonders für größere Anlagen, ist mit einem oder mehreren Lamellen (4), ähnlich der skizzierten Form, gerade oder leicht gebogen angeordnet. Die vorzugsweise äußere Lamelle (5) ist entgegen der Wind-, richtung in vorderen Teil winddurchlässig.The rotor, especially for larger systems, is arranged with one or more fins ( 4 ), similar to the sketched, straight or slightly curved. The preferably outer lamella ( 5 ) is wind-permeable against the wind direction in the front part.

Ähnlich der Skizze (Fig. II) befinden sich im vorderen Teil Luftschlitze (8) die eckig oder rund angeordnet sind.Similar to the sketch ( Fig. II) are in the front part louvers ( 8 ) which are arranged in a square or round.

Das Zentralrohr (9) ist rund oder eckig angeordnet.The central tube ( 9 ) is round or angular.
