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
Affiliated technical field
The present invention relates to vacuum pipe technology and maglev vehicle technical field, be specifically related to the vacuum pipe system of high-speed maglev train, especially the docking technique of getting on or off the bus fast of vacuum pipe magnetic-levitation train.
Background technology
Magnetic suspension train because of its safety, at a high speed, the characteristics of comfortable, low noise once extremely people attract attention.Magnetic suspension train is whole to be in suspended state with track, does not have mechanical friction, and the operation frictional resistance is very little, can reach very high speed.It is low that magnetically supported vehicle has an expenditure of energy, speed is fast as aircraft, the advantage of safety, energy-conservation environmental protection again, operation and the low advantage of maintenance cost, be that other rapid that comprises aircraft and High-speed Wheel train at present can't replace, especially have great realistic significance under the situation that the considerable energy saving of magnetically supported vehicle is seriously sounded the alarm to present oil resources.
The construction of the speed rail passenger and freight netting twine that domestic railway is continuous several ten thousand kilometers needs huge investment, expects the year two thousand twenty and reaches 4,000,000,000,000 investment.So huge investment, national government takes careful and careful attitude to make a strategic decision all the time, high speed railway construction is taked the High-speed Wheel technology or taked magnetic levitation technology, once gone through research and deliberation for a long time, even the public debate of heated dispute formula.The High-speed Wheel technology is used and is of long duration, and technology is ripe, and magnetic levitation technology is just to have risen, and application is also fewer in the world, drops into 31.5 kilometers the electromagnetic suspension passenger traffic multiple line that has only Chinese Shanghai of commercial operation.In the contrast of technical advance, the huge energy loss that the huge friction force of High-speed Wheel and track and mechanical wear produce, magnetic suspension train and track are unsettled to be floated, there is not friction force, waste of power between track and train is very little, so there is tangible technical advantage in magnetic levitation technology than High-speed Wheel.Because high speed train produces huge air resistance under steam, air resistance accounted for more than 90% when air resistance accounted for more than 80%, 500 kilometer in the time of 300 kilometers, so the technical advantage of magnetic levitation technology does not display.Owing to is the electromagnetic suspension of main flow and the track cost height of linear synchronous generator actuation techniques at present with the Germany technology, invest huge, with the competition of High-speed Wheel in be in a disadvantageous position.Make that this very promising new and high technology can not get promoting.Cost is lower, technology magnetic levitation technology appearance more cleverly so people have in expectation always.Continuous development along with technology, the vacuum pipe The Application of Technology is the obstacle that air resistance has been cleared away in maglev development, in one of percentage that is equivalent to the near-earth dense atmosphere or millesimal inferior vacuum environment, it is very small that air resistance becomes, and has only one of the percentage or the millesimal of near-earth dense atmosphere resistance.Because the air resistance in the vacuum pipe is very little, the wheel friction drag of High-speed Wheel train accounts for most proportions of whole resistances at this moment, the many and few of High-speed Wheel train and magnetic suspension train friction drag have displayed immediately, adopt the magnetic suspension train of vacuum pipe technology more energy-conservation more than 97% than the High-speed Wheel train that adopts the vacuum pipe technology, more energy-conservation 99% than aircraft, almost saved whole energy.Just make maglev low friction advantage seem especially obvious, adopt the magnetic suspension train of this vacuum pipe technology just really to reach the purpose of remarkable energy savings.
At 1850s, once the someone had proposed to set up the conception of underground vacuum line magnetic suspension train, even had taken up to implement, but underground holing, do vacuum pipe again, cost is surprisingly high, and has the potential underground potential safety hazard that breaks down and can't escape.
At present the mode of turnover train mainly adopt vacuum pipe in be provided with and isolate door and increase and decrease presses the mode in storehouse to pass in and out train, be after train arrives the destination bus stop, the long vacuum pipe at the isolation cabin goalkeeper train place of whole joint train rear and front end is airtight, long pipeline becomes the supercharging storehouse, in pipeline, feed atmosphere then, need time a few minutes when arriving standard atmosphere, open outer door and train door after supercharging storehouse and the ambient atmosphere balance again and begin passenger up and down, after the passenger enters the compartment, close the outer door of train door and pipeline, begin again the long pipeline at train place is vacuumized, long pipeline becomes the decompression storehouse, the vacuum state of being pumped into requirement needs the dozens of minutes time, open again the two ends isolation cabin behind the door train sail vacuum pipe into, this a series of actions needs the time of dozens of minutes, and is few with the aircraft takeoffs and landings time difference, and the quick advantage performance of maglev high speed is not come out.

5. running velocity height.The air resistance of train in the inferior vacuum environment of vacuum pipe have only the near-earth dense atmosphere 1% to millesimal, other resistance to motions also are reduced to very small, train just can be realized the high-speed cruising of train with energy seldom, adopt linear permanent magnet driver, equal length driving force ratio linear synchronous motor actuation techniques is more powerful, make permanent magnetic levitation train speed can reach hyprsonic, running velocity can reach 800 kilometers/hour usually, surpasses air speed.City and city even country and national distance can further further.
6. the line construction comprehensive cost is low.Do not need drive coil on the whole rail, do not need to build control branch power station on the way, do not need complicated control apparatus system yet, the construction of vacuum pipe makes no longer needs to build guard rail along the line, also can save the construction of electric pole along the line, railway construction cost along the line reduces, and personnel's maintenance cost reduces.Because the transmission magnetic gap is big, on the track working accuracy of helical stator core do not need very high, so manufacturing process is simple, low cost of manufacture.It is suitable with the High-speed Wheel construction cost that these make that the integrated cost of the magnetic suspended railway construction that linear permanent-magnet drives drops to, and this will promote popularizing and promoting of magnetic levitation technology greatly.The cost of building the vacuum pipe part has only 6,000,000 yuans/kilometer, but can save 90% air resistance energy consumption, and the expense of laying tracks of permanent magnetism but can be saved the wheel-rail train friction energy loss that accounts for 98% under the vacuum pipe technology also less than 8,000,000 yuans/kilometer.These two kinds of technology are used in combination more energy-conservation more than 97% than wheel-rail train, and are more energy-conservation 99% than aircraft, have huge economic and social value.
7. all-weather is travelled.There is the shielding of vacuum (-tight) housing the high-speed track outside, can prevent boisterous influence, makes railway no longer be subjected to the obstruct of blizzard, hail, ice rain, sandstorm weather.Can not resemble aircraft and run into thunderstorm weather and must ground, can not resemble steamer and run into wind and waves weather and must pull in to shore to suspend, can not resemble that automobile, passenger vehicle catch in a blizzard, typhoon, rain, foggy weather must underspeed and travel and will have a clear superiority in.Can accomplish that all-weather travels, stopped by neither wind or rain.
8. safe.There is the shielding of vacuum (-tight) housing the high-speed track outside, can prevent the collision of flying bird, prevent that the article (as nd-fe-b, controller etc.) of high value in the track from losing, can prevent and avoid the crowded injures and deaths phenomenon that falls in the track of personnel, vacuum (-tight) housing is equivalent to isolate railing, and is as safe as a house.High-speed Wheel train periphery also needs to build to enclose to block and guard rail, so construction cost does not have significant difference.
Not only cost is much lower than adopting subterranean tunnel formula vacuum (-tight) housing mode to adopt ground or overhead system vacuum (-tight) housing mode, and safer, take place if any abnormal condition, the overhead system vacuum (-tight) housing can be opened on the ground, communicate with atmosphere rapidly in the vacuum (-tight) housing, the passenger can deliver from godown safely.Than aircraft high-altitude in danger almost not having to survive wish safe hundred times.The floating train of permanent magnetism adopts circumferential type structure can not derail, can not overturn, than the High-speed Wheel train as small cushion block or jolt just may overturn much safe.
Vacuum pipe is very high to train and passenger safety protective action, and the destroyed gas leakage of technology pipeline can only increase gaseous tension in the pipeline, can not cause any harm to train, so it is higher to prevent to destroy and resist the safety of terrorist attacks.
9. noiselessness.There is the shielding of vacuum (-tight) housing the high-speed track outside, can intercept the unofficial biography of sound, even train passes through the city fast with speed per hour more than 800 kilometers, in needn't speed limit to 200 kilometer speed per hour, the train average speed per hour is affected, and also the phenomenon that can not cause noise to disturb residents is quiet.
10. electromagnetic-radiation-free.There is the shielding of vacuum (-tight) housing the high-speed track outside, can shield electromagnetic to external irradiation, also can be the magnetic field shielding of inner kicker magnet to identical with the earth magnetic field.Make surrounding resident not have the trouble and worry of electromagnetic interference, can be not therefore and the carrying out of the project of obstruction.
11. zero-emission.Electrification drives, and can not rely on oil and coal, does not have exhaust emission, no aerial contamination.Can build into environmentally friendly magnetic suspension traffic system, this causes harmful effect to preventing vehicle to the life of surrounding resident, promotes people's health and has very realistic meanings.
12. promote economic development.Low energy consumption is communications and transportation cheaply, brings the remarkable decline of costs of commodity circulation, drives the decline of price, to alleviating inflationary pressure, to promoting economic society sustained and coordinated development rapidly and healthily significant.
The raising of train speed has obviously been shortened between the city, interstate space-time distance.People's trip will be very convenient and swift, contacts between the each department will be frequent more quick, and substance circulating speed is obviously accelerated, and helps shortening the price gap of each department, reduce the gap of regional economy, have tangible impetus for quick raising whole nation expanding economy.
