Image collecting system of water chamber environment of steam generator

Abstract

The invention belongs to the technical field of non-destructive testing and maintenance of steam generator heat transfer tubes and similar heat exchange equipment, and particularly relates to an imagecollecting system of a water chamber environment of a steam generator. The system can collect an internal image of the steam generator during the inspection of a heat transfer tube, so that a maintenance device avoids collision with the steam generator during movement, and can also perform precision control through a video image, so that the movement accuracy of an inspection device is more accurate. The image collecting system is characterized by comprising an environment camera, a positioning camera, a switch and an industrial computer, wherein the camera transmits a video signal to an upper computer through a network switch, thereby realizing two functions of internal image collection of the water chamber of the steam generator and precision control of the video image.

Description

technical field [0001] The invention belongs to the technical field of non-destructive detection and maintenance of steam generator heat transfer tubes and similar heat exchange equipment, and in particular relates to a steam generator water chamber environment image acquisition system. Background technique [0002] In order to ensure the safe and reliable operation of the steam generator, the key equipment of nuclear power plant, its heat transfer tube must be checked and repaired regularly. The general practice is to use helium mass spectrometry leak detection, eddy current inspection and other means to regularly carry out in-service inspections of heat transfer tubes through inspection devices, and to decommission heat transfer tubes with excessive defects in a timely manner, such as plugging, so as to ensure that nuclear power plants safe operation. Nuclear power plants include nuclear power reactor types such as high-temperature gas-cooled reactors and pressurized wate...

AI Technical Summary

Problems solved by technology

Due to the unique structural limitations of the steam generator, the accuracy of the transmission mechanism of the inspection device, and the errors generated during the assembly and use of the inspection device cannot be completely eliminated, there will be certain positioning accuracy problems when implementing the inspection of the heat transfer tube.
