Rotor hub for wind turbines

A wind turbine having a nacelle with a stationary region and a rotor, at least one blocking unit for blocking the rotor, and an access control system is provided. The access control system controls a locking of at least one access door to at least one closed-off region in the wind turbine depending on a blocking of the rotor by means of the least one blocking unit. The access control system has a key transfer system and a hydraulic control unit for controlling the blocking unit. The key transfer system has a hydraulic key unit for preventing an unintentional activation of the hydraulic unit and an access door key unit for locking or unlocking the access door. The key transfer system has at least one first and second key, the hydraulic control unit being locked or unlocked by means of the first key, and the access door key unit being locked or unlocked by means of the second key, and the key transfer system also having a fan key unit for activating or deactivating a fan, the first key of the hydraulic key unit being used to lock and unlock the fan key unit and a fan key being used as a second key for locking or unlocking the access door key unit.

Wind turbine and method for controlling an access point in a closed area of a wind turbine

The present invention concerns a module carrier for fixing electric modules provided for controlling one or more pitch drives of a wind power installation to a rotor hub of the wind power installation comprising a main body for carrying the electric modules, wherein the rotor hub is adapted to rotate about a substantially horizontal rotor axis, and the main body is adapted to be fixed in front of the rotor hub in the axial direction of the rotor axis.

Components of a wind power plant

The invention relates to a device for controlling the locking of the opening of a door preferably located between the stationary part and the rotary part of a wind power plant. According to the invention, means are provided for immobilizing or stopping the rotary part, and the door between the rotary part and the stationary part of the wind power plant comprises a lock that allows unlocking and then if required opening the door when the immobilizing or stopping means have immobilized or stopped the rotary part of the wind power plant.
