Definitions

  • the invention relates to a device for quality control of rotor blades of wind power plants used to generate electricity and a method for carrying out this quality control.
  • the quality of rotor blades for wind turbines for electricity generation is determined by factors such as profile accuracy, surface quality, wall thickness, elasticity, moisture absorption and so on.
  • the rotor blades are subject to different weather and load influences, which can lead to damage to the surface such as delamination or hairline cracking even in the material depth.
  • wear and tear in particular is recognized and assessed by trained personnel by tapping the rotor blade with a hammer and evaluating the sound of the knocking noise.
  • the technical problem on which the invention is based consists in specifying a device with which a quality control of rotor blades of wind power plants serving to generate electricity is possible, and a method for carrying out this quality control.
  • the invention eliminates the disadvantages mentioned above by a largely automated and objective measurement method.
  • the invention includes the following method steps and devices:
  • a carriage called "Carrier” is placed on a vertical or horizontal rotor blade of a wind turbine and then drives the profile of the rotor blade independently or remotely, whereby various properties and possible defects of the rotor blade are recognized and measured by means of built-in sensors With a helicopter or from below, for example from a truck or ship, the rotor blade can be arranged.
  • the rotor blade can also have a position other than a vertical or horizontal position during the setting down of the carrier and the like Take test, - after the measurement is finished, the carrier is picked up again and brought to its "parking lot"; this recording is again possible, for example, with a helicopter or from a truck or ship.
