Embodiment Construction

[0016] Below in conjunction with accompanying drawing and specific embodiment this patent is described in detail:

[0017] as attached figure 1 As shown, an automatic video inspection device suitable for the anti-loosening structure of internal components of the present invention mainly includes: an omnidirectional mobile platform 1, an auxiliary camera 2, a chain-type flexible mechanical arm 3, a cable 4, a control system 5, and a refueling machine crane A hook 6, a long rod tool 7, a refueling machine 8, an underwater environment lighting lamp 9, an underwater environment camera 10, and a main video inspection camera 11 are formed.

[0018] In the present invention, the omnidirectional mobile platform 1 is located at the lowermost end of the whole set of tools, and is used to support the chain-type flexible mechanical arm 3 and move it to a suitable position. Under the control of the control system 5 , the omnidirectional mobile platform 1 can move, rotate and fine-tune in ...

Abstract

The invention belongs to the field of nuclear power maintenance, and relates to an automatic video inspection device suitable for a reactor internal anti-loosening structure. At present, a manual inspection mode is limited by field space more, the automation degree is low, and a camera cannot reach a detected area in an omnibearing mode, the tool stability is poor, and the angle of a camera is inconvenient to adjust. In the invention, a lifting hook of the nuclear island refueling machine is connected with a lifting ring at the upper end of a long-rod tool, the upper end of a chain type flexible mechanical arm is connected to the lower end of the long-rod tool, and the other end of the chain type flexible mechanical arm is fixedly connected to an omnidirectional moving platform; the lowerpart of the chain-type flexible mechanical arm extends out of the chain-type mechanical arm, and the foremost end of the chain-type mechanical arm is loaded with a main video inspection system; and anauxiliary system is arranged on the inner wall of the component pool. The automatic video inspection device is high in stability and high in automation degree, a to-be-inspected area can be comprehensively covered by video inspection, and the angle and focal length of the camera can be conveniently adjusted.

Description

technical field [0001] The invention belongs to the field of nuclear power maintenance, and relates to an automatic video inspection device suitable for anti-loosening structures of reactor internal components. Background technique [0002] The internal components of the reactor are an important part of the reactor body. They work in harsh environments for a long time. Affected by the three-dimensional flow field, the force of the secondary support components is relatively complicated. The structure is at risk of failure. The structure of the internal components of the reactor is relatively complicated. Since there is no special automatic video inspection tool, at present, the manual movement of the bridge (or the movement of the refueling trolley) is mainly used to move the long tool with the camera to the position to be inspected for inspection. This method is limited by the on-site space, the degree of automation is low, the camera cannot reach the inspected area in all ...
