Abstract

The invention is applicable to the technical field of detection and measurement equipment, and provides a video inspection and deformation measurement device for detection and measurement inside the pressure vessel of a nuclear power plant, including a base, a bracket, and a main rod body installed on the bracket and connected in sequence , the connecting rod body and the scanning component, the bracket drives the scanning component to slide on the base, the connecting rod body can be inclined relative to the main rod body, the scanning component can rotate around the axial direction of the connecting rod body, the scanning component includes a pan / tilt, a camera and a linear laser, and the camera together with The linear laser can be rotated on the pan-tilt. Through the sliding of the bracket, the inclination of the connecting rod body and the rotation of the scanning assembly, the present invention can extend the scanning assembly into the interior of the pressure vessel, and conduct all-round video detection and deformation measurement of the interior, reducing detection blind spots and avoiding the disassembly of the pressure vessel It can directly enter with the operator, which improves the detection efficiency, reduces the detection window period, and reduces the radiation dose of the operator.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant detection and measurement equipment, and in particular relates to a video inspection and deformation measurement device used for detection and measurement inside a pressure vessel of a nuclear power plant. Background technique [0002] Since the pressure vessels of nuclear power plants are responsible for important safety functions such as high-temperature and high-pressure radioactive medium storage and heat exchange, according to regulations and regulations, regular internal inspections of these vessels are required to ensure that nuclear power plants can continue to operate safely. [0003] According to the inspection hole set up in the nuclear island container of the nuclear power plant and the internal structure of the container, the current technical means have the following deficiencies: [0004] 1. Construction period and radiation exposure impact: At present, the internal insp...
