Abstract

Die mit den Wassermassen eines Flusses mitgeführten Feststoffe, Geschiebe (4) genannt, verursachen im Kraftwerkszulauf (1) von Wasserkraftwerken unerwünschte Materialansammlungen. Um ein rasches und wirkungsvolles Ausspülen des im Kraftwerkszulauf (1) abgelagerten Geschiebes (4) zu gewährleisten, wurden im Bereich der Sohle (13) des Kraftwerkszulaufes (1) Fluidkanäle (7) vorgesehen, welche quer zur Strömungsrichtung angeordnet sind und sich quer über den Kraftwerkszulauf (1) in Richtung zum Absperrschieber (6) erstrecken, wobei selbige Fluidkanäle (7) Austrittsöffnungen (8) aufweisen. Durch Aktivierung eines Kompressors (16) werden die Fluidkanäle (7) mit Druckluft beschickt, sodass das Geschiebe (7) dadurch von der Sohle (13) gelöst und über einen Spülwasserkanal (5) zurück ins Flussbett (17) abgeführt werden kann. Im Zuge des Spülvorganges wird ein zum Spülwasserkanal (5) führender Absperrschieber (6) nur über eine möglichst kurze Zeitspanne offengehalten und bleibt ansonsten geschlossen, sodass der Wasserbedarf zum Spülen von Geschiebe (4) möglichst gering gehalten und dem Triebwasserkanal (3) somit vergleichsweise wenig Wasser entzogen wird.

Figure imgaf001
The solids entrained with the water masses of a river, called bed load (4), cause unwanted accumulation of material in the power plant inlet (1) of hydroelectric plants. In order to ensure a rapid and effective rinsing of the sediment (4) deposited in the power plant inlet (1), fluid channels (7) were provided in the area of the sole (13) of the power plant inlet (1), which are arranged transversely to the flow direction and transversely across the Power plant inlet (1) in the direction of the gate valve (6), said selbige fluid channels (7) outlet openings (8). By activation of a compressor (16), the fluid channels (7) are charged with compressed air, so that the attachment (7) thereby released from the sole (13) and can be discharged via a flushing water channel (5) back into the riverbed (17). In the course of the flushing a to the flushing water channel (5) leading gate valve (6) is kept open only for a short period of time and remains otherwise closed, so that the water consumption for flushing of bed load (4) kept as low as possible and the drive water channel (3) thus comparatively little Water is withdrawn.
