Abstract
(DE)
Die vorliegende Erfindung betrifft eine Anlage mit einer Turbinenanordnung zur Umwandlung von mechanischer Energie oder kinetischer Energie aus Wasserkraft in elektrische Energie, umfassend mindestens ein um seine Mittelachse rotierend antreibbares Turbinenrad (3), dessen Schaufeln von einem strömenden Fluid, insbesondere Wasser beaufschlagt werden, wobei das Turbinenrad (3) als Hohlrad ausgebildet ist und Schaufeln des Turbinenrads (3) von radial innenseitig her von mindestens einem Wasserstrom beaufschlagt werden und wobei das Turbinenrad (3) in einem Behälter (51) rotierend angeordnet ist, welcher ein Wasservolumen aufnimmt, wobei der Behälter einen oberseitigen Zulauf (14) für einlaufendes Wasser aufweist, wobei erfindungsgemäß im zulaufseitigen Bereich des Behälters eine motorisch angetriebene Pumpvorrichtung (11) angeordnet ist, die das einlaufende Wasser einer konzentrisch innerhalb des Turbinenrads (3) angeordneten Hohlkammer (2) zuführt. Die Erfindung stellt eine Anlage mit einer Turbinenanordnung zur Verfügung, welche im Hinblick auf ihren Wirkungsgrad verbessert wurde sowie einen technisch zuverlässigen Dauerbetrieb bei möglichst geringem Wartungsaufwand ermöglicht.
(EN)
The invention relates to a system having a turbine assembly for converting mechanical energy or kinetic energy from hydropower into electrical energy, comprising at least one turbine wheel (3) which can be driven rotationally about its central axis, and the blades of which are impinged by a flowing fluid, in particular water, wherein the turbine wheel (3) is designed as a ring gear and blades of the turbine wheel (3) are impinged by at least one water flow from a radially inner side, and wherein the turbine wheel (3) is arranged rotationally in a container (51), which accommodates a water volume, wherein the container has an upper-side supply (14) for in-flowing water, wherein, according to the invention, a motor-driven pump device (11) is arranged in the supply-side region of the container, and supplies the in-flowing water to a hollow chamber (2) arranged concentrically within the turbine wheel (3). The invention provides a system with a turbine assembly, which is improved in terms of its efficiency and permits a technically reliable continuous operation with the lowest possible maintenance costs.
(FR)
La présente invention concerne une installation comprenant un agencement de turbine pour la conversion d'énergie mécanique ou d'énergie cinétique provenant d'énergie hydraulique en énergie électrique, comprenant au moins une roue de turbine (3) pouvant être entraînée en rotation autour de son axe central, les aubes de laquelle sont sollicitées par un fluide en écoulement, en particulier de l’eau, la roue de turbine (3) étant réalisée sous forme de couronne et les aubes de la roue de turbine (3) étant sollicitées à partir du côté radialement intérieur par au moins un courant d’eau, et la roue de turbine (3) étant disposée en rotation dans un conteneur (51), lequel un reçoit un volume d’eau, le conteneur comprenant une conduite d’amenée (14) sur le côté supérieur pour l’eau entrante, un dispositif de pompage (11) entraîné par moteur étant disposé selon l'invention dans la zone d‘entrée du conteneur, lequel introduit l’eau entrante dans une chambre creuse (2) disposée de manière concentrique à l'intérieur de la roue de turbine (3). L’invention concerne une installation comprenant un agencement de turbine, qui a été amélioré au regard de son rendement et qui permet un fonctionnement continu techniquement fiable pour une maintenance aussi réduite que possible.
