Detachable track connecting mechanism applied to nuclear fusion device

Abstract

The invention discloses a detachable track connecting mechanism applied to a nuclear fusion device. In the technical field of nuclear fusion reactor engineering, the detachable track connecting mechanism is applied to an annular bearing track for remote operation and maintenance of a divertor component inside a nuclear fusion device; and with utilization of the detachable track mechanism, the divertor component is separated from a track disconnection portion for realizing transport to the outside of a vacuum chamber. The detachable track connecting mechanism mainly comprises annular fixed tracks, a main detachable track body, a track cover plate, a bearing plate, bolts, a rotating shaft, insertion hole pins, and push rods and the like. During the internal component maintenance process, track dismounting and mounting can be realized quickly by using a mechanical arm front-end executer; and the component at the internal track disconnection portion of the nuclear fusion device, together with the detachable track, can be moved out of or placed into the vacuum chamber. According to the invention, the structure is simple; and the mechanism can be dismounted or mounted conveniently and rapidly and can work reliably in a vacuum and radiation environment. The quick maintenance and replacement requirements of the internal component of the vacuum chamber of the nuclear fusion device can be met; and the equipment operation efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of nuclear fusion reactor engineering, in particular to a detachable rail connection mechanism for nuclear fusion devices. Background technique [0002] At present, the research on controlled magnetic confinement thermonuclear fusion is a major research field with broad application prospects. The fusion demonstration reactor (DEMO) is the direction of the next step in the development of fusion practice after the operation of ITER, and will play an important role in maintaining and developing human civilization. The effect of estimation. The tokamak device can greatly reduce the scale and cost of the next-generation magnetic confinement fusion experimental device and the future fusion demonstration reactor, and is considered to be the most promising controllable magnetic confinement thermonuclear fusion research device for fusion energy utilization. The divertor is located at the bottom of the vacuum chamber...
