Benefits of technology

The objective of this invention is to make it safer for operators to work in the hub region of a rotor. The focus is on providing a simpler and more effective way to ensure safety, with a higher standard of safety.

Problems solved by technology

In particular, the hub of the rotor, that is a rotatable centre piece on which the rotor blades are fastened (a hub with a pitch drive is furthermore also termed a “rotor head”, however in the following the term “hub” is used as the standard form), represents a region in which it is particularly difficult and risky for the service personnel to operate.
Such procedures are very risky and furthermore complicated since the service workers have to be secured in the optimum possible way at all times.

Embodiment Construction

[0046]FIG. 1 shows a section of a rotor 1 of a wind turbine with a hub 3 which is surrounded by a rotor housing 12. The rotor 1 is formed with three vanes, i.e. it has three rotor blades (not shown in FIG. 1) protruding radially from the hub 3. Inside the hub 3 there is a tunnel-shaped hollow chamber (not shown) which serves as access from a tower (not shown) or a nacelle (not shown) of a wind turbine to connecting flanges 7 of the rotor blades 5 on the hub 3. An exit 9 connects the tunnel to a dish-like maintenance chamber 21 between the hub 3 and the rotor housing 12. Three two-prong ladder sections 10 protrude from an edge of the exit 9. An operator 16, e.g. a maintenance technician, climbs over an upper ladder section 10 in the direction of a vertex face 4 of the hub 3. The vertex face 4 forms a region of the curved surface of the hub 3 which lies between the two circular connecting flanges 7 of the rotor blades 5 of the rotor 1. In the illustrated position of the hub it offers ...

Abstract

A safety device, for ensuring the safety of an operator, is arranged in a rotor, in particular of a wind turbine. The device has a platform with a number of standing surfaces, at least one of the standing surfaces being substantially horizontal when the safety device is used as intended, and also having a securing system for securing the platform to a hub of the rotor and / or to an inner face of a rotor housing of the rotor.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is the US National Stage of International Application No. PCT / EP2013 / 056683 filed Mar. 28, 2013, and claims the benefit thereof. The International application claims the benefit of European Application No. EP13150842 filed Jan. 10, 2013. All of the applications are incorporated by reference herein in their entirety.FIELD OF INVENTION[0002]The present invention relates to a safety device for ensuring the safety of an operator for an arrangement in a rotor, more particularly a wind turbine. It furthermore relates to a method for ensuring the safety of an operator for an arrangement in a rotor, more particularly a wind turbine.BACKGROUND OF INVENTION[0003]By “rotors” are meant for example the drive propellers of aircraft, hovercraft and ships as well as also the wind and water wheels serving for obtaining energy. Wind turbines, more particularly industrial scale wind turbines, have a nacelle which is mounted on a tower, as w...
