Description
Schornsteinaufsatz Die Erfindung betrifft einen Schornsteinaufsatz, bei dem ein Windmotor zum Absaugen der Luft aus Schornsteinen nutzbar gemacht wird. In bekannter Weise trägt der Aufsatz eine drehbare Haube, die sich in die Windrichtung einstellt. Erfindungsgemäß soll nun aber dafür gesorgt werden, daß die wirksame freie Öffnung an der Lufteintrittsstelle je nach der Windstärke verschieden groß wird, um dadurch zu erreichen, daß sich die Welle des Windmotors und des mit ihr verbundenen Saugers bei jeder Windstärke annähernd gleich schnell dreht. Für diesen Zweck sind an der Eintrittsöffnung für den Wind, die exzentrisch zur Drehachse liegt, zwei schräge Leitflächen angebracht, die verschieden schräg gestellt und verschieden lang sind. Der Wind drückt auf die größere Fläche naturgemäß mit stärkerer Kraft und bemüht sich deswegen, die Haube nach einer Seite herumzudrehen. Dem wirkt in gewissen Grenzen der Winddruck auf die andere Schrägfläche entgegen, und in gleichem Sinne macht sich der auf den Auslaufstutzen drükkende Wind bemerkbar. Bei geringer Windstärke ist der Einlaßstutzen dem Wind voll zugekehrt; bei orkanartigem Wind bietet sich letzterem jedoch nur ein ganz schmaler Eintrittsspalt.Chimney attachment The invention relates to a chimney attachment, in which a wind motor can be used to extract air from chimneys. In a known way, the attachment carries a rotatable hood, which extends in the direction of the wind adjusts. According to the invention, however, it should now be ensured that the effective Free opening at the air inlet point of different sizes depending on the wind strength in order to achieve that the shaft of the wind engine and that with it connected suction device turns at almost the same speed at any wind strength. For this The purpose is at the inlet opening for the wind, which is eccentric to the axis of rotation, two inclined guide surfaces attached, the different inclined and different are long. The wind naturally pushes the larger area with greater force and therefore tries to turn the hood over to one side. That works in against certain limits the wind pressure on the other sloping surface, and in the same way The wind pressing on the outlet nozzle makes itself felt. At lower When the wind is strong, the inlet port is fully turned towards the wind; in a hurricane wind However, the latter only has a very narrow entrance slit.
In der Zeichnung ist der Schornsteinaufsatz in einem Ausführungsbeispiel dargestellt. Die Abb. i und 2 sind Draufsichten bei verschiedenen Stellungen der Schornsteinhaube, und Abb. 3 ist ein Längsschnitt durch den Schornsteinaufsatz nach der Linie 3-3 der Abb. 2.In the drawing, the chimney attachment is in one embodiment shown. Figs. I and 2 are top views at different positions of the Chimney hood, and Fig. 3 is a longitudinal section through the chimney top the line 3-3 of Fig. 2.
Das Antriebsrad 2 einer Windturbine bekannter Bauart sitzt auf der senkrechten Achse 4, auf deren unterem Ende Saugschaufeln für die -aus dem Schornstein kommenden Abgase angebracht sind. Das Rad 2 ist von einem Gehäuse 6 umschlossen, welches sich frei um die Achse 4 drehen kann und welches an der Einlaßseite für die Luft erfindungsgemäß zwei Schrägflächen 8 und 16 trägt. Die in .die Haube eintretende Luft kann bekanntermaßen teilweise durch Öffnungen 14 in einen Kanal i o gelangen, der in den Luftauslaßstutzen 12 mündet.The drive wheel 2 of a known type of wind turbine sits on the vertical axis 4, on the lower end of which suction blades for the -from the chimney coming exhaust gases are attached. The wheel 2 is enclosed by a housing 6, which can rotate freely around the axis 4 and which on the inlet side for the air carries two inclined surfaces 8 and 16 according to the invention. The one entering the hood As is known, air can partially pass through openings 14 into a channel i o, which opens into the air outlet nozzle 12.
Wird nun ein derartiger Schornsteinaufsatz der Wirkung des Windes ausgesetzt, so stellt sich die Haube 6 bei schwachem Winddruck so ein, wie es die Abb. i und 2 erkennen lassen. Der Wind kann also die volle Fläche der Schaufeln des Antriebsrades 2 treffen. Überschreitet jedoch die Windgeschwindigkeit und damit der Winddruck ein gewisses Maß, so wird die Haube 6 im Uhrzeigersinne aus ihrer gezeichneten Stellung abgelenkt, die wirksame Eintrittsöffnung für den Wind wird kleiner, und infolgedessen bleibt die Umfangsgeschwindigkeit des Rades 2 trotz der erhöhten Windgeschwindigkeit dieselbe, weil nur eine kleinere Luftmenge in das Gehäuse einzutreten vermag. Hat die Haube 6 eine gewisse Schrägstellung erreicht, so übt der auf den Auslaßstutzen i2 treffende Winddruck ein Drehmoment im entgegengesetzten Sinne aus, und es wird dadurch verhütet, daß sich die ganze Haube vollständig im Uhrzeigersinne herumdrehen kann.Now such a chimney top is affected by the action of the wind exposed, the hood 6 adjusts itself in the case of weak wind pressure as it does Fig. I and 2 can be seen. The wind can therefore cover the full area of the blades of the drive wheel 2 meet. However, exceeds the wind speed and thus the wind pressure a certain amount, the hood 6 is clockwise from their drawn position deflected, the effective entry opening for the wind is smaller, and as a result, the peripheral speed of the wheel 2 remains despite the increased wind speed the same because only a smaller amount of air enters the housing able to enter. If the hood 6 has reached a certain inclination, then practice the wind pressure hitting the outlet port i2 generates a torque in the opposite direction Senses, and it is prevented that the whole hood is completely in the Can turn clockwise.
