Die Erfindung bezieht sich auf eine Wasserkraftanlage zum Erzeugen elektrischer Energie durch Umwandlung von Strömungsenergie eines strömenden Gewässers, mit einer in einem Trog angeordneten Arbeitsschnecke, einem von dieser angetriebenen Generator und einer in gleicher Längsrichtung angeordneten gegenläufigen Fischaufstiegsschnecke. Um eine für die Fische möglichst schonende Aufstiegshilfe zwischen Unterwasser der Arbeitsschnecke und Oberwasser derselben zu erreichen ist die Eingangsöffnung 1 der neben der Arbeitsschnecke 5 liegenden Fischaufstiegsschnecke 2 mit einer Sohlanbindung 3 versehen, deren Oberfläche von deren ebenem Boden des Abströmkanals 4 der Arbeitsschnecke 5 in eine konische der Eingangsöffnung 1 der Fischaufstiegsschnecke 2 entsprechende Ebene übergeht.

It is described a rotor blade (100) for a horizontal axis wind turbine. The rotor blade (100) comprises a fixing section (107) for fixing the rotor blade (100) to a rotary shaft (105) of a rotor (110) of the horizontal axis wind turbine. Furthermore, the rotor blade (100) comprises a geometrically adjusted section (101) with a root end (108). The rotor blade (100) extends from the fixing section (107) to the root end (108). A section of the root end (108) of the geometrically adjusted section (101) and a section of a guide panel (102) of a stator (120) of the horizontal axis wind turbine closest to the root end (108) are substantially coplanar.

Wind-driven electric plant Concept of invention: a wind-driven electric plant comprises an inlet shell shaped as a circle and a circular outer shell. Inside the circular shell, provision is made of a coaxially arranged turbine. Kinematically coupled with the turbine is a mechanism for the conversion of mechanical energy. The outer shell is eccentrically mounted relative to the inlet shell. A value of eccentricity is not less than 0.01 and not more than 0.24 of the dia. of a circle defining the inside surface of the outer shell in its minimal cross section. 5 claims, dependent; 4 ill.
摘要:
An environmentally non-intrusive multiple turbine unit (210) for adjustable deployment in water. The turbines are captured in a shroud (260) having an integrally formed augmentor ring (266) and ballasting member (290) to improve efficiency. The multiple turbine arrangement effectively counteracts the rotational counter-torque of individual turbines, thereby enabling stable deployment of the unit without requiring rigid stabilizing structures.

The invention relates to a strake for a wind turbine tower. A strake 2 for a wind turbine tower 1 is disclosed, whereby the strake 2 is realized as a detachable strake to be mounted to a wind turbine tower 1 to reduce vortex induced vibrations. The strake 2 comprises an outer structure 7 and the outer structure defines three sides that are interconnected by three angles, so that the strake 2 comprises a mainly triangular shape in its cross-cut perpendicular to its longitudinal direction. The strake 2 comprises at least one element that comprises a contiguous cavity 8 that is filled with a fluid.
