Description

Strahlteiler zur Vermeidung von Wehrschwingungen an überströmten Wehrklappen Die Erfindung betrifft eine weitere Ausbildung der Strahlteiler mit einer Belüftungseinrichtung für Klappen nach Patent 693 01o. Die Strahlteiler nach dem Hauptpatent eignen sich jedoch nur für Wehrklappen mit stark gekrümmter Stauwand, deren Krümmung sich an die Oberwasserspiegelebene anschmiegt. Der Strahlteiler nach der Erfindung soll dagegen bei steil stehenden Klappen mit gerader oder nur wenig gekrümmter Stauwand in Anwendung kommen, deren Stauwandebene finit dem Wasserspiegel einen steilen Winkel bildet. Auch hier soll der Raum unterhalb der Klappe und des überfallenden Wasserstrahles unmittelbar an seinem Scheitel mit der Außenluft verbunden werden.Beam splitter to avoid weir vibrations at weir flaps overflowing with flow. The invention relates to a further embodiment of the beam splitter with a ventilation device for flaps according to patent 693 01o. However, the jet splitters according to the main patent are only suitable for weir flaps with a strongly curved retaining wall, the curvature of which clings to the upper water level. The jet splitter according to the invention, on the other hand, is intended to be used for steeply standing flaps with a straight or only slightly curved retaining wall, the retaining wall plane of which forms a steep angle finite with the water level. Here, too, the space below the flap and the incident water jet should be connected to the outside air directly at its apex.

In den Fig. z bis 5 der Zeichnung ist die Ausbildung eines derartigen Strahlteilers dargestellt.In Figs. Z to 5 of the drawing, the formation of such a Beam splitter shown.

Die dachförmig miteinander verbundenen Leitbleche b werden in einem Ausschnitt o der Stauwand q an dieser unmittelbar befestigt, und zwar so, daß die scharfe Kante nach der Oberwasserseite und der gespreizte untere Teil auf die Unterseite der Stauwand der Klappe zu liegen kommt. Die Leitbleche b ragen mit ihren Stirnseiten f so weit übereden oberen Rand der Stauwand q hinaus, daß die Auskragung e mindestens der Dicke .des überfallenden Wasserstrahles entspricht, die sich beim Umlegen der Klappe in der schwingungsgefährdeten Bewegungszone ergibt. Die Stirnkanten f der Leitbleche b werden so ausgeführt, daß diese parallel zu dem Überfallenden Wasserstrahl verlaufen. Dadurch wird verhindert, daß der überfallendeWasserstralil in die durch die erfindungsgemäße Maßnahme geschaffene Öffnung c eindringt. Die Belüftungsöffnung c verbindet nunmehr den Raum d unterhalb der Klappe und des überfallenden Wasserstrahles an seine:ii Scheitel unmittelbar mit der Außenluft.The roof-shaped interconnected baffles b are attached directly to a cutout o of the dam wall q, in such a way that the sharp edge on the upstream side and the spread lower part come to rest on the underside of the dam wall of the flap. The baffles b protrude with their end faces f so far beyond the upper edge of the retaining wall q that the projection e corresponds at least to the thickness of the falling water jet, which results when the flap is folded in the movement zone at risk of vibration. The front edges f of the baffles b are designed so that they run parallel to the overflowing water jet. This prevents the attacking water storm from penetrating into the opening c created by the measure according to the invention. The ventilation opening c now connects the space d below the flap and the falling water jet at its: ii vertex directly with the outside air.
