Vacuum pipeline docking technology and high-speed permanent maglev train system

Abstract

The invention provides a vacuum pipeline docking technology and a high-speed permanent maglev train system. With the station-training docking technology, the door closing time of the maglev train inside the vacuum pipeline can be shortened for scores of seconds, so the rapid on-off can be realized. When a telescopic door and a separation cabin door are withdrawn to be close to the wall of the vacuum pipeline, the high-speed pass of the tray is free from being influenced. The telescopic door is locked by a permanent magnet suction disc, and the locking force is free from being controlled by the electric power, so the gas leakage and pressure relief caused by the invalid locking for sudden power down can be prevented. The energy can be remarkably saved, the energy can be saved by more than 97 percent compared with that of high-speed track train, and the energy can be saved by more than 99 percent compared with that of the airplane.

Description

Technical field [0001] The invention relates to the technical field of vacuum pipeline technology and maglev vehicle, in particular to a vacuum pipeline system of a high-speed maglev train, in particular to a docking technology for fast getting on and off of a vacuum pipeline maglev train. Background technique [0002] Maglev trains have attracted much attention because of their safety, high speed, comfort and low noise. The maglev train is in a suspended state with the track as a whole, there is no mechanical friction, and the running friction resistance is very small, and it can reach a high speed. The maglev vehicle has the advantages of low energy consumption, fast speed like an airplane, safety, energy saving and environmental protection, and low operation and maintenance costs. The remarkable energy-saving performance of maglev vehicles has far-reaching practical significance in the situation that the oil resources are seriously sounding the alarm bell. [0003] The ...

Problems solved by technology

[0004] In the 1850s, someone once proposed the idea of ​​building an underground vacuum pipeline maglev train, and even started to implement it. However, digging underground tunnels and making vacuum pipelines is surprisingly expensive, and there are potential underground failures that cannot be achieved. escape safety hazard

[0005] At present, the way of getting in and out of the train mainly adopts the way of setting the isolation compartment door and the increase and decrease compartment in the vacuum pipeline to enter and exit the train, that is, after the train arrives at the destination stop, the isolation compartment doors at the front and rear ends of the whole train will seal the long vacuum pipeline where the train is located. , the long pipeline becomes a pressurized cabin, and then the atmosphere is introduced into the pipeline. It takes a few minutes to reach the standard atmospheric pressure. After the pressurized cabin is balanced with the outside atmosphere, the outer door and the train door are opened to start getting on and off the passengers. After the passengers enter the compartment , close the train door and the outer door of the pipeline, and then start to vacuumize the long pipeline where the train is located. The long pipeline becomes a decompression chamber. It takes tens of minutes to pump to the required vacuum state, and then open the isolation doors at both ends and the train Driving into the vacuum pipeline, this series of actions takes tens of minutes, which is about the same as the take-off and landing time of an airplane, so that the high-speed and fast advantages of maglev cannot be brought into play.
