Abstract
The invention discloses a low-air-pressure pipeline for a maglev vehicle system to go through. The low-air-pressure pipeline is composed of a vacuum pipeline (1) and a bottom support (2). The vacuum pipeline (1) is composed of an internal support (1.1) and organic glass (1.2) arranged on the internal support (1.1). The bottom support (2) is composed of a base plate (2.1) and a base (2.2) arranged on the base plate (2.1) and used for supporting the vacuum pipeline (1). The vacuum pipeline (1) and the bottom support (2) are connected into a whole to form an airtight negative-pressure pipe environment. A multi-fulcrum beam-like structure is adopted in the base, the height can be adjusted according to the terrain, and therefore the engineering problem caused by uneven grounds can be effectively solved. Through the pipe wall of the organic glass, the running condition of a maglev vehicle in the pipeline can be well presented and conveniently detected by the exterior. In addition, passengers can have good view in the maglev vehicle and better experience of the maglev vehicle. According to the invention, a low-air-pressure pipeline environment close to the vacuum can be achieved in the pipeline, and the maglev vehicle system can efficiently run in a low-damping and low-energy-consumption environment.
Description
Technical field:
The present invention relates to vehicular transport circuit and environment, especially current magnetic floats the infrabar pipeline of truck system.
Background technology:
The mankind never stopped the technology pursue to express traffic.At present, the record of ground rail vehicle highest running speed is 603km/h.Dense atmosphere is the basic factor that restriction track vehicle improves speed further.Such as, under air environment, the normal ground rail vehicle speed run is more than 500km/h, and its air resistance accounts for more than 92% of overall resistance, already beyond can the scope of economical operation, no matter and count roughly the noise pollution of 100dB.If wish to break through track vehicle velocity limit further, create the high-speed carriering tool of a new generation, then need to consider fundamentally to reduce or eliminate air resistance.Therefore an actv. technical thought is exactly, and builds and is applicable to vehicle borne infrabar plumbing system, allow vehicle run in rarefied air environment, reach or exceed the running velocity (about 1000km/h) of aircraft.Once had theoretical computation chart bright, and the atmospheric gas pressure of running space was pumped into 1 ‰ atmospheric vacuum, if magnetic is floated truck system be installed on this, average velociity is expected to reach 6750km/h, considerably beyond the running velocity of aircraft.And this for vehicle borne infrabar pipeline same together with orbit along track laying, meet the basic characteristics of ground track vehicle, combine with technique is high, and development prospect is wide.
This infrabar pipeline, and even vacuum pipe, in conjunction with different application occasion, from concept design to theory calculate, obtain some more convictive notional results.Ripe in conjunction with technological direction such as modern material technique, computing machines, automatically control, high speed railway, high temperature superconductor magnetic levitation vehicle, building up one becomes a kind of possibility for vehicle borne infrabar pipeline.On the other hand, along with society is to environmental protection, the energy, sight, recreational, interactive, and the technical requirements such as strength of material under vacuum environment, a kind of intensity of implementation success is reliable, leak tightness is high, cost is low, environmental protection become this technical field problem in the urgent need to address for vehicle borne infrabar pipeline.
Summary of the invention:
In view of the above deficiency of prior art, the object of this invention is to provide a kind of vehicular transport of low-drag and the road environment of operation; Its technical scheme is as follows:
Current magnetic floats the infrabar pipeline of truck system, is made up of vacuum pipe 1, underframe support 2, and vacuum pipe 1 is made up of inner support 1.1 and organism glass 1.2 placed on it; Underframe support 2 is by substrate 2.1 and placed on it forming for the base 2.2 supporting vacuum pipe 1; It is an entirety that vacuum pipe 1 and underframe support 2 connect, and forms the pipeline environment of an air-tightness negative pressure.
As preferably, the inner support 1.1 of vacuum pipe 1 is that steel structure frame supports, and organism glass 1.2 is high strength, lightweight, high molecular polymerization material, and is transparent material.
In the specific implementation, also need to do corresponding consideration to the details implemented:
Curved or the linear of whole infrabar pipeline is arranged.
Consider the change of physical features, make the adjustment on height for reply physical features, base 2.2 adopts branched some beam type structure.
To expand with heat and contract with cold the sealing demand caused for adapting to pipeline because of external temperature, at vacuum pipe connection segment place, pipeline adopts the mode of adhesion, and the material of filling has certain retractility.
Adopt structure of the present invention, reduce or eliminate air resistance, break through track vehicle velocity limit further, for the high-speed carriering tool creating a new generation provides experiment porch.At infrabar plumbing system, vehicle is allowed to run in rarefied air environment, reach or exceed the running velocity (about 1000km/h) of aircraft, and this same as with common locomotive orbit track laying for vehicle borne infrabar pipeline, meet the basic characteristics of ground track vehicle.
Vacuum pipe is made up of inner support and organism glass placed on it; The support of vacuum pipe inside adopts steel structure frame supporting way.The utilization of its steel structure, strengthens the intensity of pipeline, prevents the pipe collapse because negative pressure causes.Organism glass has good light transmission features due to it, can represent maglev vehicle running condition in the duct well, is convenient to the running condition of magnetically supported vehicle in extraneous testing pipes on the one hand; Make passenger can have the good visual field in riding process on the other hand, make its ride experience more comfortable.In addition, the high strength of organism glass, is enough to resist the pressure that in pipeline, negative pressure is brought, ensure that the reliability service of maglev vehicle reliable and securely.At connection segment place, pipeline adopts the mode of adhesion, and the material of filling has certain retractility, and pipeline can be avoided to expand with heat and contract with cold the sealing problem caused because of external temperature.Base, for supporting vacuum pipe, adopts branched some beam type structure, can make the adjustment on height, effectively overcome the engineering problem because ground unfairness causes, be conducive to construction and the enforcement of infrabar vacuum pipe according to physical features.
