Description

Selbstregelndes Klappenwehr. Die Erfindung bezieht sich auf ein um eine wagerechte Achse drehbares, durch Wasserdruck selbsttätig sich regelndes Klappenwehr. Der Drehpunkt befindet sich im Angriffpunkt des bei geschlossener Klappe und vollem Aufstau eintretenden Wasserdrucks (unterer Drittelpunkt).Self-regulating flap weir. The invention relates to a a horizontal axis rotatable flap weir that is automatically regulated by water pressure. The pivot point is at the point of attack of the closed and full flap Accumulation of incoming water pressure (lower third point).

Die Zeichnung stellt einen Querschnitt der Klappe dar, und zwar in Abb. i und 2 in geschlossener und geöffneter Lage der Klappe. Der Hohlraum a dient dazu, ein Gewicht (Beton oder Alteisen) aufzunehmen. Da die Klappe in sich blegungsfest ist, wird sie nur an den Seiten gelagert. Die Größe der Abflußöfüung zwischen Wehrschwelle und Klappe wird so geregelt, daß sich die Stauwand bei einer bestimmten Wasserführung umlegt.The drawing shows a cross section of the valve, namely in Fig. I and 2 in the closed and open position of the flap. The cavity a serves to pick up a weight (concrete or scrap iron). Because the flap is inherently resistant to deformation it is only stored on the sides. The size of the discharge opening between the weir threshold and flap is regulated so that the retaining wall is at a certain water flow kills.

Der Drehpunkt b ist nicht genau an den Angriffpunkt des Wasserdruckes gebunden sondern vom günstigsten Stand der statischen Momente abhängig; er ist in den Angriffpunkt b der Resultierenden des Wasserdrucks bei geschlossenem Wehr und vollem Auftau gelegt. Das Wehr ist also im Gleichgewicht, wenn der Wasserspiegel mit der Wehroberkante gleichsteht. Liegt der Wasserspiegel tiefer als die Oberkante des Wehres, so greift auch die Resultierende des Wasserdrucks unter dem Drehpunkt b an und preßt dadurch das Wehr gegen die untere Dichtung. Das Wehr bleibt dadurch geschlossen.The pivot point b is not exactly at the point of application of the water pressure bound but dependent on the most favorable state of the static moments; he is in the point of application b of the resultant of the water pressure when the weir is closed and fully thawed. So the weir is in equilibrium when the water level equals the upper edge of the weir. If the water level is lower than the upper edge of the weir, the resultant of the water pressure below the pivot point also takes effect b and thereby press the weir against the lower seal. The weir remains closed.

Unter den Drehpunkte ist die Stauwand zurückgesetzt, um einen Hohlraum a zur Aufnahmeeines Gewichts zu bilden, welches die Klappe aus der geneigten Lage wieder in die senkrechte Stellung zurückdrückt. Dieses Gewicht kann aus Beton, Alteisen oder auch nur aus Wasser gebildet werden, je nach dem Stand der statischen Momente.The retaining wall is set back under the pivot points around a cavity a to take up a weight, which the flap from the inclined position back into the vertical position. This weight can consist of concrete, scrap iron or just formed from water, depending on the state of the static moments.

Steigt nun der Wasserspiegel über die obere Kante des Wehres, so greift auch die Resultierende des Wasserdrucks über dem Drehpunkt an, und die Klappe neigt sich nach hinten über. Gleichzeitig damit rückt - die Stauwand von der unteren Dichtung ab und gibt dadurch einen Spalt frei, durch welchen das Wasser mit erhöhter Geschwindigkeit über die Wehrschwelle abfließt.If the water level rises above the upper edge of the weir, take action also shows the resultant of the water pressure above the pivot point, and the flap tilts over to the back. At the same time, the retaining wall moves away from the lower seal and thereby releases a gap through which the water can flow at increased speed flows over the weir threshold.

Fließt weniger Wasser zu, als durch den Spalt abfließt, so sinkt der Spiegel wieder unter die Oberkante des Wehres, und die Resultierende des Wasserdrucks in Verbindung mit dem Gewicht im Raum a stellen die Klappe wieder in die senkrechte Stellung (Abb. i).If less water flows in than flows out through the gap, it sinks Mirror again under the top of the weir, and the resultant of the water pressure in connection with the weight in space a, place the flap in the vertical position again Position (Fig. I).

Steigt der Wasserspiegel dauernd weiter und kann der Spalt an der unteren Wehrkante die gesamte Wassernvenge nicht mehr abführen, so legt sich die Klappe in eine wagerechte Stellung um (Abb. a). Das Wasser fließt nun über und unter der. Stauklappe ab. In dieser Stellung bleibt die Klappe, bis das Gewicht im Raum a die Wasserauflast auf der Klappe überwindet, d. h. bis der Weserspiegel auf eine bestimmte Höhe gefallen ist; dann stellt sich die Klappe wieder senkrecht.If the water level continues to rise and the gap in the lower weir edge no longer drain the entire water vein, so the Flip over to a horizontal position (Fig. A). The water now flows over and under the. Storage flap off. The flap remains in this position until the weight is in the room a overcomes the water load on the flap, d. H. until the Weserspiegel on one a certain height has fallen; then the flap turns upright again.
