The invention belongs to the technical field of nuclear power station lossless inspection equipment application and relates to a heat transfer pipe seal weld remote-control automatic penetration detection device. The detection device comprises a penetration inspection module, a mechanical transport and positioning device, a control sub-system and a storage and measurement sub-system. The penetration inspection module is installed on the mechanical transport and positioning device. The control sub-system positions and controls the mechanical transport and positioning device. The mechanical transport and positioning device transports the penetration inspection module to a designated position close to seal weld to be subjected to penetration inspection. The control sub-system controls the penetration inspection module so that a corresponding automatic penetration inspection process is finished under control. The storage and measurement sub-system displays and stores inspection images obtained by the penetration inspection module, carries out image analysis and display two dimensional size measurement and builds an inspection result database. The detection device can reduce high radiation-caused damage to the human body and improve inspection result effectiveness and accuracy.
Description
technical field [0001] The invention belongs to the technical field of application of nondestructive inspection equipment in nuclear power plants, and in particular relates to a remote control automatic penetration inspection device for heat transfer tube sealing welding. Background technique [0002] At present, in the penetration inspection of heat transfer tube sealing welding or plugging welding in the field of nuclear industry, artificial coloring method is often used for inspection. Because this part belongs to the main part of the primary circuit, the environmental radiation is very high, which is harmful to the human body; at the same time, the harsh working environment may lead to insufficient rigor of inspection implementation and unobjective accuracy of inspection results. For this reason, it is necessary to design a remote automatic penetration inspection device for heat transfer tube sealing welding. Contents of the invention [0003] The object of the presen...
