technical field

The utility model relates to the field of transportation, in particular to a vacuum pipeline transportation system.

Background technique

Evacuated Tube Transportation is a form of transportation without air resistance and friction. Its basic idea is to place the magnetic levitation system in a closed pipeline that is evacuated to a certain degree of vacuum. Since there is no restriction of mechanical resistance and air resistance, It is also not affected by weather conditions, and the maglev train can run at a speed several times that of an airplane in the pipeline. This idea was first proposed in 1904. U.S. Patent US 5950543 first disclosed a specific technical solution of the vacuum pipeline transportation system, including: two vacuumed pipelines along the line direction, car body, vacuum equipment, suspension components, Acceleration device, brake system capable of recovering energy, vibration damping device, pipe locator, frog system, automatic control, detection and maintenance device, construction method, safety system, etc.

Vacuum pipeline transportation is ultra-high speed, low energy consumption, low noise, and low pollution. It is considered to be a new generation of transportation in the future, but it has not yet entered the stage of commercial operation. A company in the United States plans to commercialize the vacuum pipeline transportation system. It is considering placing an aluminum manned cabin in a steel pipeline, launching it through a launcher, and propelling it forward in a state of magnetic levitation. However, this kind of pipeline is heavy, which is not conducive to building on elevated roads, and requires high foundation support, resulting in increased costs; in addition, the manufacturing process of steel and aluminum will cause environmental pollution, is not environmentally friendly, and will consume limited mineral resources.
