INSPECTION DEVICE FOR STEAM GENERATOR

The invention relates to an inspection device for a steam generator, capable of inspecting whether foreign matters exist in gaps of a heat conduction tube bundle or not. In order to solve the above-described problem, an embodiment of the present invention provides an inspection device for a steam generator comprising: a flange attached to a hand hole of a steam generator; a frame attached to the flange; a pulley mounted on the frame; a guide rail mounted along the outer side of a heat conduction pipe bundle in the steam generator through the hand hole; a moving unit which is wound on the pulley and can move on the guide rail; a drive unit for driving the pulley; and a camera unit attached to the moving unit so as to be able to move forward and backward between the heat conduction pipe bundle. 本发明涉及一种能够对导热管束的缝隙中是否有异物存在等进行检查的蒸汽发生器检查装置。为了解决如上所述的课题，适用本发明的一实施例提供一种蒸汽发生器检查装置，包括：凸缘，安装在蒸汽发生器的手孔上；框架，安装在上述凸缘上；滑轮，安装在上述框架上；导向轨道，通过上述手孔沿着上述蒸汽发生器内部的导热管束的外侧进行安装；移动部，缠绕在上述滑轮上，可在上述导向轨道上进行移动；驱动部，用于对上述滑轮进行驱动；以及，摄像头部，以可在上述导热管束之间前进后
