Abstract: The invention relates to a grinding tool for grinding a leading edge of a wind turbine blade. It comprises two parallel shafts of which at least one is rotationally driven and a frame for holding the two shafts in a fixed mutual relationship. An annular abrasive belt is arranged around a tension device mounted to the frame and guides of which there is one on each of the two shafts. The abrasive belt runs in a plane perpendicular to the shafts and has a longer length than an imaginary curve formed by outer surfaces of the tension device and of the guides. The grinding tool further comprises two abrasive belt retainers movably mounted to the frame. They are shaped and arranged to move between a retaining position in which they retain the abrasive belt along at least parts of the abrasive belt which is in contact with the guides, and a release position in which they are out of contact with the abrasive belt.

Abstract: A wind turbine (1) comprising a tower (2), a nacelle (3) and a hub (7) is disclosed. The hub (7) comprises a blade canying structure (4) with one or more wind turbine blades (5) connected thereto. Each of the wind turbine blades (5) is connected to the blade canying structure (4) via a hinge (6) at a hinge position of the wind turbine blade (5), each wind turbine blade (5) thereby being arranged to perform pivot movements relative to the blade carrying structure (4) between a minimum pivot angle and a maximum pivot angle. The wind turbine (1) further comprises a stop mechanism arranged to move the wind turbine blades (5) to a safe pivot angle in the case of an emergency, the stop mechanism comprising a release mechanism (8, 12, 14) and at least one wire (9, 10) interconnecting the release mechanism (8, 12, 14) and each of the wind turbine blades (5). Activation of the release mechanism (8, 12, 14) causes an abrupt change in a pulling force applied to the wind turbine blades (5) by the wire(s) (9, 10), the change in pulling force causes the wind turbine blades (5) to move immediately to the safe pivot angle.

Abstract: A coating applicator tool head configured for use with a robotic maintenance device includes a tool head body with a frame, a supply container, a drive for actuating delivery of flow of coating from the supply container, a feed tube, a nozzle receiving flow from the feed tube, and a spreading tool such as a roller brush or a spatula receiving flow from the nozzle. The coating applicator tool head is moved by an articulated arm of the maintenance device over surface of a wind turbine blade containing damage such that the roller brush or spatula can apply layers of the coating to cover and fill in the damage. The nozzle directly supplies coating continuously onto the roller brush or the spatula, and the drive can be configured to independently adjust supply of two or more different components in the supply container that may be mixed to form the coating.

Abstract: A payload coupler with a position control device for controlling a position of the payload coupler when suspended from a lower end of a line for attachment at an upper end thereof to a lifting device. The payload coupler includes a payload attachment means and at least two propulsors. The payload attachment means couples to and/or decouples from a payload and is arranged to directly couple the payload coupler to a payload. The propulsors are configured to generate resultant propulsion forces which are non-parallel and having at least a component perpendicular to the axis of the line when the line is hanging taut under gravity.

Abstract: In a first example there is provided a method of servicing a wind turbine rotor blade. The blade comprises an outer shell defining an interior cavity, and the rotor blade is part of a rotor connected to a wind turbine. The method comprises arranging the rotor such that the 5 blade is in a first orientation, installing a work platform in the interior cavity of the blade when the blade is in the first orientation, and subsequently arranging the blade in a second orientation. The method further comprises using the work platform, when the blade is in the second orientation, to support a technician performing a service operation on the blade.

Abstract: An applicator tool (42) is provided for use with a robotic maintenance device (40) for 5 repairing damage (26) around a leading edge (22) of a wind turbine blade (20) on a wind turbine (10). The applicator tool (42) includes a tool frame (70) and a spatula (76) defining a flexible extrusion plate (78) that is configured to be engaged with an exterior surface (34) of the wind turbine blade (20), and a nozzle (84) that delivers a coating material (30) into a gap (112) between the extrusion plate (78) and the blade 0 (20). At least two nozzles (84) and corresponding fluid supplies may be provided to extend a working capacity of the applicator tool (42). The applicator tool (42) also includes a first chamfer arm (80) and a second chamfer arm (82) each configured to engage an outer surface (100) of the extrusion plate (78) adjacent a front edge (94) thereof to press the extrusion plate (78) against the exterior surface (34) of the blade 5 (20) at two specific engagement locations. The spatula (76) is configured to shape the coating material (30) into a shaped coating as the coating material (30) spreads in the gap (112) to thereby fill in and cover the damage (26) on the wind turbine blade (20), and the first and second chamfer arms (80, 82) are configured to limit spread of the coating material (30) beyond the two specific engagement locations 0 such that the shaped coating applied to the wind turbine blade (20) extends only between a first chamfer line (36) and a second chamfer line (38) on opposite sides of the leading edge (22). The applicator tool (42) also includes a vision system (160) configured to image the blade (20) to detect whether the first and second chamfer lines (36, 38) are located at expected positions to determine if any overfill or underfill 5 condition needs corrected. as well as a repair verification scanner (180) that detects a coating layer thickness of the shaped coating to further confirm whether a repair is performed as expected.
