AI Technical Summary

Technical Problem

In the existing technology, the process of removing the turbulence-causing elements from wind turbine blades is time-consuming and labor-intensive, lacking a reliable and efficient method, which increases the workload of wind turbine blade installation.

Method used

A fusible detachment device for a wind turbine blade spoiler element is designed. By using the cooperation of a ratchet disc and a pawl disc, the positioning rope is burned off through a heating circuit, so that the spoiler element can be reliably and efficiently detached from the wind turbine blade. The device includes a sleeve, an end cap, a ratchet disc, a pawl disc, and a power supply device.

Benefits of technology

This achieves reliable and efficient detachment of the turbulence-causing element, reducing the workload of wind turbine blade installation and improving installation efficiency.

Abstract

A fusing type disengaging device of a wind power blade turbulent flow element is characterized in that a half rope ring, close to one side of a hub, of a rope is arranged in a rope winding ring groove in the outer wall of an end cover of a sleeve in a sleeving mode, a fusing assembly in the end cover is provided with a power supply device and a plurality of conducting strips, and conduction can be avoided through the elastic force of a torsional spring in a locking state; the pawl disc can rotate relative to the ratchet wheel disc to the separation position where the pawl and the ratchet are mutually blocked, at the moment, due to the fact that the conducting strips stay to the mutual contact position after rotating, the conducting parts at the two ends of the power supply device can be mutually conducted to form a heating loop, and heat of the heating loop can be transmitted to the rope winding ring groove to burn out the positioning rope. Therefore, the positioning rope can be separated from the end cover, the turbulent flow element can be reliably and efficiently separated from the wind power blade, an operator only needs to pull the traction rope at will, and the workload in the wind power blade installation process is greatly reduced.
