    • Internal components of power generation machinery, including for example gas or steam industrial turbines as well as generators, are inspected a camera inspection system that is inserted and positioned within the machinery by an elongated cable carrier that has restricted cable flexure along a two-dimensional carrier cable flexure motion plane. A camera head that retains the camera is coupled to a distal end of the cable carrier. Embodiments also include a connector block coupled between the cable carrier distal end and the camera head. The connector block has a pivot axis coupled to the camera head for swinging the camera head along a camera head range of motion path that intersects the cable carrier flexure motion plane. Embodiments include a camera head swing motion drive system for selectively positioning the camera head along the camera head range of motion path.
    • 发电机械的内部组件,包括例如气体或蒸汽工业涡轮机以及发电机,对通过一个细长的电缆载体插入和定位在机械内的照相机检查系统进行了检查,该电缆承载器沿着二维载体 电缆弯曲运动平面。 保持相机的相机头连接到电缆托架的远端。 实施例还包括连接在电缆承载件远端和相机头之间的连接器块。 连接器块具有联接到照相机头的枢转轴线,用于沿着与电缆载体弯曲运动平面相交的运动路径的相机头部范围摆动照相机头部。 实施例包括用于沿着运动路径的照相机头部范围选择性地定位相机头的相机头旋转运动驱动系统。

    • Internal components of gas and steam turbines are inspected with an optical camera inspection system that is capable of automatically and/or manually positioning the camera field of view (FOV) to an area of interest within the turbine along a pre-designated navigation path and capturing images with or without human intervention. Camera positioning and image capture can be initiated automatically or after receipt of operator permission. The inspection system includes an articulated multi-axis inspection scope with an optical camera that is inserted through a combustor nozzle access port, combustor and transition, so that the camera FOV captures the leading edge of Row 1 rotating turbine blades while the rotor is spinning at up to 1000 RPM. An illumination system strobe light and the camera image capture are synchronized with the blade rotation speed so that images of multiple or all blades may be obtained from a single inspection scope insertion point.
    • 气体和蒸汽涡轮机的内部组件用光学相机检查系统进行检查,该系统能够沿着预先指定的导航路径自动和/或手动将照相机视场(FOV)定位到涡轮内的感兴趣区域并捕获 有或没有人为干预的图像。 相机定位和图像捕获可以自动启动或在收到操作者许可后启动。 检查系统包括铰接式多轴检查镜,其具有通过燃烧器喷嘴入口,燃烧器和过渡部插入的光学摄像机,使得摄像机FOV在转子旋转时捕获行1旋转涡轮叶片的前缘 高达1000 RPM。 照明系统闪光灯和相机图像捕获与刀片旋转速度同步,使得可以从单个检查范围插入点获得多个或所有刀片的图像。
