Problems solved by technology

[0003] The purpose of the present invention is to propose a movable protection mechanism for diagnostic devices in a tokamak vacuum chamber, which can protect the diagnostic devices within a large stroke range in an ultra-high vacuum and high temperature operating environment, and solve the problem of high temperature drying. The deformation of the components caused by baking may cause the technical problem of the mechanism being stuck

Abstract

The invention discloses a movable protection mechanism for a Tokamak vacuum indoor diagnosis device, which comprises a sliding baffle for protecting the diagnosis device, wherein, the movement of the sliding baffle is controlled by a first steel wire rope and a second steel wire ropes fixedly linked on the sliding baffle; under the leading of a fixed pulley, the first steel wire rope and the second steel wire rope respectively enwind on a first disk and a second disk on a transmission shaft and are respectively fixedly linked with the first disk and the second disk; and the rotation of the transmission shaft is realized by a vacuum mechanical rotating shaft through a coupler. The first steel wire rope and the second steel wire rope are drawn and released on the first disk and the second disk by rotating the vacuum mechanical rotating shaft, thereby realizing the forward and backward movement of the sliding baffle in a support track so as to protect the diagnosis device when being opened or closed. The movable protection mechanism avoids the phenomenon that high-temperature roasting probably leads to the fixed clamping of a long-stroke mechanism. The movable protection mechanism is successfully applied to protecting EAST superconducting Tokamak H(alpha) diagnosis devices (optical mirrors), and ensures that the reflecting mirrors are not damaged during the processing course of vacuum walls.

Description

technical field [0001] The invention belongs to a movable protection mechanism for devices in a tokamak vacuum chamber, in particular to a movable protection mechanism for diagnostic devices in a tokamak vacuum chamber. Background technique [0002] Controllable magnetic confinement thermonuclear fusion research is a research field of great significance in the current natural science research. The establishment of commercial fusion reactors will play an inestimable role in maintaining and developing human civilization. The Tokamak device is considered to be the most promising controllable magnetic confinement thermonuclear fusion research device. Its basic principle is to use a strong magnetic field to confine the plasma in a clean ultra-high vacuum chamber, and use peripheral heating equipment to confine the plasma It is heated to a high temperature of hundreds of millions of degrees to meet the conditions of fusion reaction, so as to carry out experimental research on toka...
