Description

Bei fast allen bisher in Gebrauch befindlichen Maschinen zur Ausnutzung der Windkraft handelt es sich um Flügelräder mit horizontaler Welle und schräg gestellten Flügeln. Der Nutzeffekt beruht auf der Zerlegung der Windkraft, weswegen nur ein Teil der Windkraft nutzbar gemacht wird.Almost all machines that have been in use so far the wind power is about impellers with a horizontal shaft and inclined Wings. The efficiency is based on the decomposition of the wind power, which is why only one Part of the wind power is harnessed.

Nur selten und ohne rechten Erfolg wurde versucht, Windturbinen mit vertikaler Welle zu verwenden. Die Wirkung dieser Turbinen beruht darauf, daß die Flügel schaufelförmig gebogen sind und der Winddruck auf die Konkavseite der Flügel voll wirkt, währender an der Konvexseite teilweise abgleitet. Der auf diese Weise erzielte Nutzeffekt genügte nicht, um solche Anlagen wirtschaftlich zu machen.Attempts to use wind turbines were seldom and with no real success vertical wave to use. The effect of these turbines is based on the fact that the Wings are curved in the shape of a scoop and the wind pressure on the concave side of the wings acts fully, while partially slipping on the convex side. That way The efficiency achieved was not sufficient to make such systems economical.

Bei nachstehend beschriebener und in schematischer Zeichnung dargestellter Neuerung soll der Nutzeffekt solcher Turbinen dadurch erhöht werden, daß die sich gegen den Wind drehenden Teile der Turbine durch einen Vorbau gegen den Wind völlig abgeschirmt werden, so daß der Winddruck nur die Teile trifft, die sich mit dem Winde drehen und demselben die Konkavseite ihrer Flügel zuwenden.When described below and shown in a schematic drawing The innovation is to increase the efficiency of such turbines in that the parts of the turbine rotating against the wind by a porch against the wind completely shielded so that the wind pressure only hits the parts that are in contact with the Turn the winch and turn the concave side of its wings towards it.

Die schematische Darstellung' zeigt die hauptsächlichen Teile einer derartigen Maschine. Es stehen zwei gleichartige Turbinen nebeneinander; ihre Flügel sind schaufelförmig gebogen; die Krümmung ist an der Spitze der Flügel am stärksten. Die beiden Turbinen a und a1 sind mit ihren Wellen oben und unten in einem kreisförmigen Rahmen b gelagert, und zwar mit- einem Abstand von 120°, gemessen an dem Rahmen. Durch die beiden Turbinenwellen wird also der Rahmen in ein kürzeres Stück von 12o° und ein längeres von 2q0° geteilt. In der Mitte des letzteren ist zwischen den beiden Rahmen und auf dieselben aufmontiert ein keilförmiger Windschirm c angebracht, dessen Breite gleich dem Abstand der beiden Turbinenwellen ist, also auch 12o° beträgt. Zwischen dem Windschirm und den Turbinenwellen bleibt somit beiderseits ein Abstand von 6o°; der Windschirm reicht also bis unmittelbar an die Turbinen heran. Die Spitze des Windschirms muß möglichst genau in den Wind gerichtet sein. Der untere Rahmen ist drehbar gelagert und das Drehen der Maschine nach dem Wind kann durch die Bedienung derselben oder durch eine .der bisher gebräuchlichen automatischen Vorrichtungen bewirkt werden.The schematic diagram shows the main parts of a such machine. There are two turbines of the same type next to each other; their wings are curved in the shape of a scoop; the curvature is greatest at the tip of the wings. The two turbines a and a1 are in a circular shape with their shafts above and below Frame b stored, namely at a distance of 120 °, measured on the frame. The two turbine shafts make the frame into a shorter piece of 12o ° and a longer one divided by 2q0 °. In the middle of the latter is between the two Frame and mounted on the same a wedge-shaped windshield c attached, its Width is the same as the distance between the two turbine shafts, i.e. also 12o °. There is thus a gap on both sides between the windshield and the turbine shafts of 6o °; the windshield therefore comes right up to the turbines. The summit the windshield must be directed as precisely as possible into the wind. The lower frame is rotatably mounted and the turning of the machine according to the wind can be done by the operator the same or by one of the previously used automatic devices be effected.

Der Wind wird durch den keilförmigen Windschirm gezwungen, nach beiden Seiten auszuweichen. Der Winddruck trifft nur die äußeren Hälften der Turbinen, deren Flügel so gestellt sind, daß der Wind auf die Konkavseite trifft. In der äußeren Hälfte der Turbinen werden die Flügel vom vollen Winddruck herumgedreht, während sie sich in der inneren Hälfte in bewegungsloser Luft zurückdrehen, ohne wesentlich gehemmt zu werden.The wind is forced through the wedge-shaped windshield, towards both Dodging sides. The wind pressure only hits the outer halves of the turbines, whose wings are placed so that the wind hits the concave side. In the outer Half of the turbines, the blades are turned around by full wind pressure while they turn back in the inner half in motionless air, without essential to be inhibited.

Das Ausweichen des Windes vor dem Schirm bewirkt ferner, daß sich Windgeschwindigkeit und Winddruck beiderseits des Schirms verstärken, der Druck auf die Turbinenflügel somit vergrößert wird. Endlich trifft, indem der Wind den Schirm umfließt, der Winddruck unter günstigerem Winkel auf die Turbinenflügel, als wenn der Schirm fehlen würde. Diese günstigen Nebenwirkungen des Windschirms sind in der Zeichnung durch die gestrichelten Pfeile in der rechten Hälfte, welche die Ablenkung des Windes andeuten, veranschaulicht.The evasion of the wind in front of the screen also causes itself Wind speed and wind pressure on both sides of the screen increase the pressure is thus enlarged on the turbine blades. Finally, as the wind hits the The screen flows around the wind pressure at a more favorable angle on the turbine blades, as if the screen were missing. These beneficial side effects of the windshield are in the drawing by the dashed arrows in the right half, which indicate the deflection of the wind, illustrated.

Die beiden Turbinen drehen sich entgegengesetzt; ihre Bewegung wird auf eine zentrisch liegende Welle d übertragen.The two turbines rotate in opposite directions; their movement will transferred to a centrally located shaft d.
