Definitions
- the invention relates to a wind turbine with a tower with a gondola at the top of the tower and a rotor arranged on the gondola with a rotor hub and at least one rotor blade and with an intermediate piece between the rotor hub and the rotor blade, the intermediate piece having a first flange on the Rotor hub is attached and has a second flange for attaching a rotor blade thereon.
- Such a wind turbine is known from WO 01/42647 and - like the mass of the known wind turbines - is designed as a so-called windward rotor, i. that is, the rotor is located on the wind turbine side of the tower of the wind turbine.
- the impinging wind bends the rotor blades towards the tower and there is a risk of a rotor blade colliding with the tower, especially when there are strong gusts of wind. At least damage or even destruction of the rotor blade and / or the tower is possible.
- This object is achieved according to the invention in that the planes of the flanges of the intermediate piece enclose a predetermined acute angle, and the intermediate piece is attached to the rotor hub in such a way that the acute angle opens towards the tower.
- the invention is based on the finding that, due to the mechanical structure of a rotor blade, the area of the blade tip is particularly strongly deformable and is therefore at risk of collision.
- the rotor blade in the installed state runs from the rotor blade root with an increasing distance from the tower to the rotor blade tip.
- the intermediate piece has at least one through hole. This through hole allows, if it is designed as a manhole, access to the interior of the intermediate piece to z. B. To be able to carry out fastening work or maintenance work.
- Figure 1 shows a known intermediate piece
- Figure 2 shows an intermediate piece according to the invention
- Figure 3 is a simplified representation of a rotor hub
- Figure 4 shows a wind turbine according to the invention.
- the intermediate piece shown in FIG. 1 comprises a first flange 10, a second flange 12 and a cylindrical section 14 running therebetween. attached hub, the second flange 12 is available for attaching the rotor blade. Since the two flanges 10, 12 are formed in parallel, the rotor blade will run in the direction predetermined by the surface of the hub.
- Figure 2 shows an intermediate piece according to the invention. This also has a first flange 10, a second flange 12 and an intermediate cylindrical section 14. However, the flanges 10, 12 do not run parallel to each other, but at a predetermined acute angle a (a is approximately between 0.5 ° - 15 °). If this intermediate piece shown in FIG. 2 is fastened to the rotor hub with the first flange 10, the second flange 12 is deflected in accordance with the angle between these two flanges 10, 12.
- FIG. 3 This is shown in FIG. 3 in a simplified representation.
- the reference numeral 20 denotes a tower of a wind turbine
- the reference numeral 18 denotes a machine carrier, to which a rotor hub 16 is attached.
- Two intermediate pieces 10, 12, 14 according to the invention are attached to the rotor hub 16.
- Each of the intermediate pieces 10, 12, 14 is fastened to the rotor hub 16 with a flange 10.
- the intermediate pieces 10, 12, 14 are aligned in such a way that the angle a between the first flange 10 and the second flange 12 opens towards the tower of the wind turbine.
- the rotor blades 22 attached to the second flanges 12 are thus inclined away from the tower 20 of the wind energy installation by an angle ⁇ and with increasing distance from the rotor hub 16, the distance between the rotor blade 22 and the tower of the wind energy installation 20 increases.
- the reference numeral 20 in turn denotes the tower of a wind power installation
- the reference numeral 24 denotes a nacelle in which the generator, the drive train and the rotor hub (not shown in this figure) are accommodated.
- the rotor blades 22 attached to the rotor hub extend from the nacelle 24 with increasing distance from the tower 20 of the wind turbine.
- the angle ⁇ enclosed by the flanges (reference numerals 10, 12) in FIGS. 1-3 determines the measure (angle ⁇ ) of the increase in the distance of the rotor blades from the tower 20 of the system.
