Abstract

The invention belongs to television automatic checking for the inner surfaces of a penetrating piece of a top cover of a pressure container of a nuclear power station reactor and other pipe fittings and particularly relates to a television checking camera combination structure for the inside of the pipe fitting. The television checking camera combination structure for the inside of the pipe fitting comprises a cylinder cover. A top cover board is arranged at the top of the cylinder cover; a combination structure body is arranged in the cylinder cover; the bottom of the combination structure body is fixedly connected with a positioning plate; four cavities are formed on the combination structure body; a bracket is arranged in the cavity at the top of the combination structure body; a camera is arranged on the bracket; the cavity at the middle upper part of the combination structure body is provided with a reflector; a camera is arranged at the lower part of the reflector; a supporting rod is arranged at the middle lower part of the combination structure body; the middle position of the supporting rod is connected with a scraper frame; and the scraper frame is connected with a nylon scraper. The television checking camera combination structure for the inside of the pipe fitting has the advantage of implementing functions of excellent illumination, clear imaging, camera waterproofness and the like by steering the light, regulating the brightness and setting a suitable optical path.

Description

technical field [0001] The invention belongs to a nuclear power plant reactor pressure vessel top cover penetrating piece and other pipe fitting inner surface automatic inspection by television, in particular to a combination structure of a television inspection camera inside the pipe fitting. Background technique [0002] The top cover of the reactor pressure vessel is a hemisphere with an inner diameter of SR890mm and a wall thickness of 157mm, with the top facing upwards, like a pot with its mouth facing downwards. Many penetrations are installed on the top cover. The inner diameter of the penetrations is Ф70mm and the wall thickness is 17.5mm. The lower part of the penetrations is welded to the inner wall of the top cover through a J-shaped weld to form the pressure boundary of the main system of the primary circuit of the nuclear island. The interior of the top cover penetration accommodates the control rods that control the operation of the reactor, and is also the cha...
