Abstract (en)
[origin: WO2009012977A2] The present invention relates in an entirely general form to an installation (1) for production of energy from a fluid flow, preferably the production of so-called renewable energy from water power, and relates in particular to an incidence angle adjustment and holding apparatus for a blade (5, 5') of an installation (1) such as this, wherein a plurality of blades (5, 5') are arranged, in each case axially and radially at a distance from one another, along a driveshaft (6) of the installation (1), and wherein each blade (5, 5') is detachably attached to the driveshaft (6) at its end facing the driveshaft (6), by means of a holding device which produces an interlock in the axial direction of the blades (5, 5'), and each blade (5, 5') is designed such that it can be rotated and fixed by means of an adjusting device, in the installed state, on a plane at right angles to the axial direction A of the blades (5, 5') and relative to the driveshaft (6); furthermore, a blade (5, 5') according to the invention and a housing according to the invention comprising a multiplicity of tubular segments (2) for an installation (1) such as this, as well as a ball-bearing head (12) in order to support the driveshaft (6), are described and placed under protection.
