Patent number: 9046078Abstract: The invention relates to a rotor blade for a wind power plant comprising a rotor blade body, wherein the rotor blade body encloses a hollow space, wherein the rotor blade body comprises a penetration for draining the hollow space, and a functional element, wherein the functional element is displaceably connected to the rotor blade body and is disposed at the penetration. According to the invention, the functional element can be transferred from a closed position into an open position, wherein the functional element can be displaced purely by translation. Improved drainage is thereby achieved and clogging of the drain is prevented, with reduced noise production.Type: GrantFiled: March 11, 2011Date of Patent: June 2, 2015Assignee: Kenersys GMBHInventor: Alexander Miller

Patent number: 8757973Abstract: An adjusting device for adjusting the rotation angle position of the rotor of a wind energy system should be improved by the invention, whereby a complicated processing of the brake disc previously used for engagement of the drive is no longer necessary, and whereby said brake disc can be flexibly arranged in an area with sufficient construction space. For this purpose, the adjusting device has at least one force transducer wheel and/or a force transducing disc which is mounted or can be mounted on a shaft (1) of the drive train which is switched downstream from the rotor, which is structured for engagement of a force transmitting means, and is designed as an independent component. The device also has a drive means for producing a drive force, and at least one force transmission means for transmitting the drive force to the force transducer wheel and/or the force transducing disc.Type: GrantFiled: August 11, 2009Date of Patent: June 24, 2014Assignee: Kenersys GmbHInventors: Michael Hüsken, Ulf Nosthoff, Ulrich Uphues, Markus Becker

Patent number: 8482149Abstract: What is disclosed is a wind turbine comprising a tower with a closable climbing opening and electrical components disposed inside the tower. In order to provide said wind turbine with the ability to provide a cooling system for cooling the electrical components, in particular the electrical components disposed in the area near the base of the tower, said cooling system able to be cost-effectively installed, it is proposed that the door opening of the wind turbine be located in a continuous tower port which is larger than the door opening, with air intake and exhaust openings passing through said tower port for passage of cooling air.Type: GrantFiled: April 14, 2009Date of Patent: July 9, 2013Assignee: Kenersys GmbHInventors: Ulrich Uphues, Markus Becker
