Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046]It should be noted that when a component is referred to as being “fixed on” or “disposed on” another component, it may be directly or indirectly on the other component. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element. The orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are for convenience of description only, rather than indicating or implying the referred device Or elem...

Abstract

The invention is applicable to the technical field of detection and measuring equipment, and provides a video inspection and deformation measuring device used for detecting and measuring inside a pressure vessel of a nuclear power plant. The device comprises a base, a bracket, a main rod body, a connecting rod body and a scanning component, wherein the main rod body, the connecting rod body and the scanning component are arranged on the bracket and are connected in sequence. The bracket drives the scanning component and the like to slide on the base. The connecting rod body can be inclined relative to the main rod body. The scanning component can rotate about the axial direction of the connecting rod body. The scanning component comprises a holder, a camera and a linear laser. The camera and the linear laser can rotate on the holder. According to the invention, through the sliding of the bracket, the tilting of the connecting rod body and the rotation of the scanning component, the scanning assembly can stretch into the pressure vessel to perform all-round video detection and deformation measurement on the inside; the detection dead zone is reduced; disintegration of the pressure vessel is avoided, and an operator is prevented from directly entering the pressure vessel; the detection efficiency is improved; the detection window period is reduced; and the radiation dose of the operator is reduced.

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...
