Abstract: A wind turbine with a nacelle with a nacelle floor is thus provided. The wind turbine further has an aerodynamic rotor with at least two rotor blades. The wind turbine further has a tower, on which the nacelle is arranged. At least one first and second opening are provided in the nacelle floor. The first opening is used to transport first components of the wind turbine, and has corresponding first dimensions. The second opening has second dimensions, and is used to transport a transformer into the nacelle. The transformer has a floor that closes the second opening when the transformer has been conveyed through the second opening into the nacelle and mounted in the nacelle.

Abstract: A coupling device for coupling tower segments, which are arranged on one another, of a tubular tower of a wind power installation, having a coupling plate for contact against a circumferential surface of the tower segments, which are arranged on one another, in an abutting region, comprising a fastening portion having a first contact surface for arranging on a circumferential surface of a first tower segment and a connecting portion having a second contact surface for arranging on a circumferential surface of a second tower segment, and at least one through-opening.

Abstract: A wind turbine comprising a tower, a pod, at least one smoke detector in the region of the tower and/or in the region of the pod, at least one fan arranged in the tower and/or in the pod, and a control unit which detects a fire situation or smoke development in the wind turbine by means of the smoke detectors and activates the fans disposed in the tower and/or in the pod in order to suck away the smoke produced.

Abstract: A flange connection for a wind turbine, in particular a blade flange connection, having—a first flange part, in particular a blade receptacle of a rotor blade hub, a second flange part, in particular a rotor blade flange, and multiple bolts which hold the second component against the first flange part in a connected state, wherein the bolts are each screwed to the first flange part. It is proposed that the at least two bolts are in each case connected to one another by a tension means, a sensor arrangement, which detects a change in a tensile force transmitted by the tension means, being actively connected to the tension means. A wind turbine and a method for monitoring the flange connection of the wind turbine are also proposed.
