Abstract

The invention discloses a vacuumizing device used in a vacuum pipeline and a vacuumizing method of the vacuumizing device. The vacuumizing device comprises an external vacuumizing device arranged outside the vacuum pipeline and an internal vacuumizing device arranged inside the vacuum pipeline; the internal vacuumizing device comprises a wind shielding hood, a driving mechanism and a gas collection device, wherein the wind shielding hood is arranged at the head of a high speed train and is used for being matched with the inner wall of the vacuum pipeline at the periphery of the head of the high speed train after being unfolded, the driving mechanism is connected with the wind shielding hood and is used for driving the wind shielding hood to open and close, the gas collection device is arranged to be in cut-through with a wind collection channel of the wind shielding hood, and the gas collection device is fastened to the high speed train. Through the structural design, vacuumizing work inside the vacuumizing pipeline can be conveniently achieved through the foldable wind shielding hood, the vacuumizing efficiency is improved, balanced air pressure inside the vacuum pipeline can be flexibly maintained according to a preset air pressure value of the vacuum pipeline, and therefore the vacuumizing work is conveniently and efficiently conducted on the vacuum pipeline.

Description

technical field [0001] The invention relates to the technical field of high-speed trains, in particular to a vacuuming device and a vacuuming method for a vacuum pipeline. Background technique [0002] High-speed trains are the development direction of modern high-tech rail transportation. After the high-speed rail with wheel-rail technology reaches a speed of 400KM / h, there is no room for higher development due to the reduced friction between the wheels and rails. The way to achieve higher speed train running speed can also adopt the magnetic levitation system, which realizes the non-contact suspension and guidance between the train and the track through electromagnetic force, and then uses the electromagnetic force generated by the linear motor to pull the train to run. At present, the maglev train system can be divided into two directions, namely the constant conduction magnetic attraction (EMS) train adopted by Germany and the superconducting magnetic repulsion train (ED...
