Abstract
A robot serves for inspecting rotor blades of wind energy installations. A frame construction includes an inner opening surrounding a rotor blade during use and a plurality of propellers for a vertical flying movement of the robot. A rotor blade state detection system disposed at the frame construction detects the state of the rotor blades. Preferably a power and/or data cable is provided for connecting the robot during use to a control and evaluation station provided, for example, on the ground.
Claims11
A robot for inspecting rotor blades of wind energy installations, the robot comprising:
- a free-floating frame construction that is self-contained and independent of catenary suspensions, the frame construction including an inner opening which surrounds a rotor blade during use;
- a plurality of propellers arranged on the frame construction for a vertical flying movement of the robot, each of the propellers driven by a propeller motor;
- a rotor blade state detection system disposed on the frame construction for a contactless inspection of a rotor blade during use;
- a cable provided for connecting the robot to a station directly or indirectly located on the ground or on a vehicle;
- a docking and/or guiding system for docking and/or guiding the robot to/on a rotor blade, the docking and/or guiding system comprising a guide for moving the robot upwards and downwards along a rotor blade during use, the guide being driven by a guide motor;
- and
- a control device that jointly controls the propeller motors and the guide motor.
