A recently filed patent (Publication Number: US20230193878A1) describes a segment for a Scruton helix, a type of structure used in wind turbines. The segment includes a segment body, a coupling device for connecting it to another segment, and a push-on device for attaching it to a rope. The push-on device has a projecting region that hooks behind the rope, and the segment body defines a rope channel that partially surrounds the rope. This allows the segment to be shifted along the rope.

The push-on device also has an access region that allows the segment to be easily applied to and removed from the rope. The rope channel and the access region define an angle of greater than 0°, providing flexibility in the positioning of the segment. The segment body has a support surface for stability on a base, and the push-on device has a recessed region that forms both the rope channel and the access region.

The patent also describes a system for a Scruton helix, which includes multiple segments connected to each other and to a rope. The segments are designed to be easily coupled to the rope and to each other. The patent further describes a Scruton helix tower for a wind turbine, where the helix is arranged in a spiral around the tower.

Additionally, the patent outlines a method for mounting a Scruton helix. The method involves fitting a segment onto a rope by rotating it relative to the rope, and then coupling the segment to the rope. Multiple segments can be fitted onto the rope and coupled to each other by shifting them along the rope.

Overall, this patent introduces a new segment design for a Scruton helix, along with a system and method for mounting the helix. These innovations aim to improve the efficiency and ease of installation of Scruton helix structures in wind turbines.
