AI Technical Summary
Conventional inspection methods for wind turbine blades in wind power generation facilities are costly and inefficient, often requiring an inspection opening in the main tower, which is impractical and costly to maintain.
An inspection device comprising a first rail on the outer surface of the main tower, an imaging device with a moving unit and imaging unit, and a control device, which allows for imaging and inspection of wind turbine blades without penetrating the main tower, using a rechargeable battery and charging device, and includes features like rotating parts and storage compartments for the imaging device.
The solution enables low-cost and accurate inspection of wind turbine blades by positioning them opposite the rail for close imaging, reducing maintenance costs and improving inspection accuracy through AI-based image recognition, and allowing day and night inspections.
