Embodiment Construction

[0048] FIG. 1 shows a detail of a rotor 1 of a wind turbine with a hub 3 which is surrounded by a rotor housing 12 . The rotor 1 is designed as a three-bladed structure, ie it has three rotor blades (not shown in FIG. 1 ) protruding radially from the hub 3 . There is a tunnel-like cavity (not shown) inside the hub 3, which serves as a channel from the wind turbine tower (not shown) or nacelle (not shown) to the rotor blade 5, the channel of the connecting flange 7 on the hub 3. The tunnel connects the outlet 9 to a shell-shaped service room 21 between the hub 3 and the rotor housing 12 . Three correspondingly double-runned ladder sections 10 protrude radially from the edge of the outlet opening 9 . An operator 16 , for example a service technician, climbs onto the upper ladder section 10 in the direction of the top side 4 of the hub 3 . The top surface 4 forms a region of the curved surface of the hub 3 which is located between two circular connecting flanges 7 of the rotor...

Abstract

The invention relates to a safety device (19) for ensuring the safety of an operator (16), said device being arranged in a rotor (1), in particular of a wind turbine. The device comprises a platform (20) with a number of standing surfaces (32), at least one of said standing surfaces (32) being substantially horizontal when the safety device (19) is used as intended, and also comprising a securing system (18, 28) for securing the platform (20) to a hub (3) of the rotor (1) and / or to an inner face (14) of a rotor housing (12) of the rotor (1).

Description

technical field [0001] The invention relates to a safety device for protecting an operator for an arrangement, in particular in a rotor of a wind turbine. Furthermore, the invention relates to a method for protecting an operator in the case of an arrangement, in particular in a rotor of a wind turbine. Background technique [0002] "Rotors" are, for example, the driving propellers of aircraft, helicopters and ships, as well as the wind and water wheels used to generate energy. A wind turbine, in particular a large-scale wind turbine, has a nacelle arranged on a tower and a rotor supported on the nacelle. The rotor represents the moving part of the wind turbine. It is connected to the interior of the nacelle, where the generator and other electrical and electronic components are typically located, by means of a rod on the drive train. Within the scope of the present invention, a “rotor” is understood to mean the totality of a hub, rotor blades fastened to the hub, and a ro...
