AI Technical Summary

Problems solved by technology

Positioning of inspection devices is challenging due to the complex and often circuitous maneuvering paths between components in a gas turbine
The scope camera delivery system must be soft enough to pass through the narrowed channel, but not too soft or weak to prevent getting stuck in the channel

Embodiment Construction

[0030] Upon consideration of the following description, it will be apparent to those skilled in the art that the teachings of the present invention can be readily utilized in a camera mirror inspection system having a flexible cord mounted camera head capable of Manipulation in restricted internal lumens. Camera head position sensing systems determine the three-dimensional (3D) position of the camera head within the machine being inspected by extrapolation. The camera head position data is associated with the camera image data by the controller. In this way, the associated internal inspection image data and corresponding location data are available for future analysis and image tracking.

[0031] refer to Figure 1 to Figure 3 , embodiments of the present invention facilitate automated off-line remote visual inspection of gas turbine 30 internal components including compressor section 32, combustor section 34, first row and second row of stationary blades 42 of turbine secti...

Abstract

A camera scope inspection system with a flexible, tether mounted camera head that is maneuverable in confined internal cavities of power generation machinery. A camera head position sensing system inferentially determines the three dimension (3D) position of the camera head within the inspected machinery. Camera head position data are correlated with camera image data by a controller. In this manner correlated internal inspection image data and corresponding position data are available for future analysis and image tracking.
