Abstract

The invention provides an TV automatic checkout equipment for the water chamber inner surface of a nuclear steam generator, comprising a guide rail, a support platform, a large arm, a telescopic boom, a forearm, a rotating arm, a yawing arm, a ribbed slab, a support and a steel plate; two ends of the support are supported on the surface of the guide rail and the inner surface of a manhole respectively; the guide rail is connected with a flange; one end of the guide rail is arranged on the ribbed slab; a monaural on the side wall of the other end of the guide rail is connected with one end of the steel plate; the other end of the steel plate is connected with a monaural on the other location of the corresponding side of the support platform; the other side of the support platform is connected with one end of the large arm, the other end of the large arm is connected with the telescopic boom, the forearm, the rotating arm and the yawing arm in sequence. The device of the invention can have an overall inspection on the stainless overlaying layer of the water chamber surface of the steam generator so as to find if crackles, collision tracks, scratches, corrosive defects, abnormal indication or foreign objects exist.

Description

technical field [0001] The invention relates to an automatic inspection device, in particular to a television automatic inspection device for the water chamber surface of a nuclear steam generator. Background technique [0002] The nuclear steam generator is the key equipment in the nuclear power plant circuit system, and it plays a very important role in the safe, reliable and economical operation of the nuclear power plant. Due to its very harsh working conditions and long-term work under high temperature, high pressure, and high radiation conditions, opening defects such as cracks and corrosion are extremely prone to occur. In order to ensure the safety of nuclear power plants, according to the relevant regulations on pre-service and in-service inspections of nuclear power plants, a corresponding inspection system must be used to regularly conduct a comprehensive inspection of the stainless steel surfacing layer on the surface of the steam generator water chamber to find ...
