GUIDE WIRE TENSION LOSS SENSOR

摘要

Systems and devices are described for measuring tension in a guide wire in a tower service lift for ascending and descending wind turbine generator towers. The present disclosure also describes methods for measuring the tension in the guide wire as well as installing a device for measuring the tension in the guide wire.

主权项

1. A system comprising:
a wind turbine generator tower; a rigging mounted to an interior portion of the wind turbine generator tower, wherein the rigging is configured to be movable in a substantially vertical direction along the interior portion of the wind turbine generator tower; a drive mechanism mechanically connected to the rigging and mounted to an upper portion of the wind turbine generator tower, wherein the drive mechanism is operable to move the rigging in a substantially vertical direction; a lift mechanically connected to the rigging, wherein the movement of the drive mechanism is operable to actuate the lift to be raised or lowered in a substantially vertical direction along the interior portion of the wind turbine generator tower; a guide wire mounted to a lower portion of the wind turbine generator tower and mechanically connected to the lift; a tension system spring mechanically connected to the guide wire and mounted to the lower portion of the wind turbine generator tower, wherein the tension system spring is configured to maintain tension during movement of the lift or movement of the wind turbine generator tower; and a tension loss sensor connected to the guide wire, wherein the tension loss sensor is configured to detect movement of the tension system spring.
