Abstract
The disclosure relates to the methods and devices for wind turbine blade mechanical de-icing. The proposed method for de-icing of a wind turbine blade, includes the steps of positioning a wind turbine blade in a substantially horizontal position; pulling a line one over the wind turbine blade; and pulling both ends of the line one sideways parallel to the wind turbine blade. The line one can be provided with a line two attached to it and the method may further include the step of pulling up a joint connecting the lines one and two to the leading edge and using the line one to slide the joint position over the leading edge of the blade. According to an embodiment an elastic sliding plate configured to prevent line entanglement may be attached at the line one and two joint position.
Claims8
A method for de-icing of a wind turbine blade, comprising:
- (i) positioning the wind turbine blade in a horizontal position;
- (ii) positioning a pitch of the wind turbine blade with a leading edge of the wind turbine blade pointing upwards;
- (iii) pulling a line one over the wind turbine blade, wherein a line two is connected to the line one at a joint position by a joint;
- (iii′) pulling up the joint to the leading edge of the wind turbine blade and using the line one to slide the joint position over the leading edge of the wind turbine blade;
- and
- (iv) pulling both ends of the line one sideways parallel to the wind turbine blade.
