Superexpress train domestic demand maintains normal pressure, and there are air disclosure risk, security risk is high.
Summary of the invention
The purpose of this utility model is that in view of the deficiencies of the prior art, providing a kind of ultrahigh speed pipeline drag reduction method, solve
Certainly existing its transport pipeline of hypervelocity train is difficult to the problem of maintaining vacuum, reduces the operating cost of superexpress train.
The technical solution adopted in the utility model are as follows: a kind of twin flue superexpress train mainly includes Outer Tube, interior conduit
And car body, the Outer Tube and interior conduit are coaxially arranged；Length direction along interior conduit is equipped with rail, the car body and rail phase
Adaptation, and moved along the length direction of rail；Multiple inner tube pump drainage ports, inner tube pump drainage port and sky are offered on interior conduit
The entrance of gas exhaust apparatus is connected to, and the outlet of air exhaust apparatus is connected to airflow channel.The airflow channel is set to Outer Tube
It is arranged between interior conduit, and along the length direction of Outer Tube.
According to the above scheme, the airflow channel is connected to the interior conduit outside car body tail end, and air is sprayed from interior conduit
Direction is opposite with the traffic direction of car body.
According to the above scheme, multiple outer tube pump drainage ports being communicated with the atmosphere are offered on the Outer Tube, the air-flow is logical
Road is connected to outer tube pump drainage port.
According to the above scheme, said inner tube road is equipped with ventilating system.
According to the above scheme, said inner tube pump drainage port is respectively along the circumferential direction of interior conduit and axis direction uniform intervals cloth
It sets.
The utility model has the following beneficial effects:
1, the utility model uses twin flue, and interior conduit is the running track of superexpress train, and air is arranged in Outer Tube
The air of interior conduit can be evacuated to the external world or sent to the interior conduit of rear vehicle by exhaust apparatus；
2, the utility model internal channel within the train unacceptable time, can be kept normal without maintaining vacuum state always
Pressure condition；The more economical rationality compared with authentic vacant duct, it is easy to accomplish, the cost of superexpress train can be effectively reduced；
3, the utility model reduces train in car body by the air of the air especially car body front end of preceding pump drainage interior conduit
Running resistance；Meanwhile the air of pump drainage is sent to hull back, provides forward motive force for the operation of car body；When car body slows down,
Stop pump drainage or reduce the air of pump drainage car body front end, increases air drag, help to stop；
4, the utility model outer tube pump drainage port is communicated with the atmosphere, and can periodically realize the ventilation of interior conduit, in guarantee
The air quality of pipeline；
5, the structure design of the utility model is reasonable, operation and it is easy to maintain, reduce superexpress train construction cost and
The running cost for maintaining vacuum condition, reduces project cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of one specific embodiment of the utility model.
Fig. 2 is Fig. 1 section structure diagram.
Wherein: 1, car body；2, interior conduit；3, Outer Tube；4, inner tube pump drainage port；5, air exhaust apparatus；6, outer tube is taken out
Exhaust outlet；7, airflow channel；8, rail.
Specific embodiment
The utility model in order to better understand is in the following with reference to the drawings and specific embodiments made the utility model further
Ground description.
A kind of twin flue superexpress train as depicted in figs. 1 and 2, mainly include Outer Tube 3, interior conduit 2 and car body 1,
The Outer Tube 3 and interior conduit 2 are coaxially arranged；Length direction along interior conduit 2 is equipped with rail 8, the car body 1 and 8 phase of rail
Adaptation, and can be moved along the length direction of rail 8；Multiple inner tube pump drainage ports 4, inner tube exhaust are offered on interior conduit 2
Mouth 4 is connected to the entrance of air exhaust apparatus 5, and the outlet of air exhaust apparatus 5 is connected to airflow channel 7；The air pump drainage
Equipment 5 is set between Outer Tube 3 and interior conduit 2.Preferably, the airflow channel 7 is set between Outer Tube 3 and interior conduit 2, and
Length direction along Outer Tube 3 is arranged.
Preferably, the airflow channel 7 is connected to the interior conduit 2 outside 1 tail end of car body, and air is sprayed from interior conduit 2
Direction is opposite with the traffic direction of car body 1.
Preferably, multiple outer tube pump drainage ports 6 being communicated with the atmosphere, the airflow channel 5 are offered on the Outer Tube 3
It is connected to outer tube pump drainage port 6.
Preferably, said inner tube road 2 is equipped with ventilating system；Said inner tube pump drainage port 4 is respectively along the circumferential direction side of interior conduit 2
To and axis direction uniform intervals arrangement.
In the utility model, car body 1 should fill up interior conduit 2 as far as possible, and gap between the two is the smaller the better.For interior conduit
2 atmospheric density can be determined according to the speed requirement and 5 ability integration of air exhaust apparatus of car body 1；Speed is more than 1000km/
H reduces the atmospheric density of interior conduit 2, makes its interior atmospheric density close to vacuum.Due to the sliding of wheel track, rolling resistance and air
Resistance is compared, and is not the principal element for limiting superexpress train speed and improving, therefore can still use steel wheel, rail system, is used for
Carry the self weight of superexpress train.The utility model can be also directly set up on overhead, directly be changed using overhead position advantage
Air quality in kind interior conduit 2.
Finally it should be noted that the above is only the preferred embodiment of the utility model, it is not limited to practical
