Abstract

PROBLEM TO BE SOLVED: To increase the speed of a traveling body, conduct stable traveling, improve economical, and relieve environmental problems by making a traveling body travel in a decomposed efficiency duct in order to decrease traveling resistance by atmosphere of the traveling body. SOLUTION: This traveling device is provided with a duct 1 to materialize decompressed environment at the time of traveling of a traveling body 4, an exhaust blower 3 for exhausting air from the duct 1 to maintain the decompressed environment, and an airtight door 2 to open and close, if necessary, for stable air pressure in a traveling section at the time of traveling of the traveling body 4 provided at the duct 1. The inside of the traveling body 4 is maintained at the atmospheric pressure, therefore, getting-on/off a platform 8 is made by an extendable type airtight getting-on/off device 7 such as telescopic to maintain the airtightness of the duct 1. As a result, traveling can be conducted with smaller air resistance than in the atmosphere, therefore, it is possible to decrease traveling consuming energy, conduct high-speed traveling, and improve an economic property. It is also possible to relieve environmental problems such as vibration and noise to the outside of the duct.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to increasing the speed of an on-orbit or trackless vehicle and reducing energy consumption in order to increase the efficiency of transportation and distribution of people.

[0002]

2. Description of the Related Art It is indispensable for economic development to enable a person or an object to be moved efficiently by a higher-speed traveling body. For this reason, conventional railways do not always arrive at destinations in a short period of time, and conventional railways have limited rail running resistance and driving force when traveling at high speeds. The resistance increases significantly. In addition, the conventional method has technical, economic, and environmental problems, such as the occurrence of environmental problems such as vibration and noise due to air pressure fluctuations during high-speed driving, and also being affected by strong winds, rain, and snow outside. was there.

[0003]

SUMMARY OF THE INVENTION The present invention makes it possible to increase the speed of a traveling body and to enable stable traveling by drastically reducing the air resistance during high-speed traveling of the traveling body. At the same time, it is to increase economic efficiency and alleviate environmental problems.

[0004]

In order to reduce the running resistance of the traveling body due to the atmosphere, the traveling system is arranged such that the traveling of the traveling body is in a reduced-pressure duct, and the duct and a decompression device for reducing the pressure in the duct. An air-tight door that opens and closes as necessary when the traveling body is traveling to maintain the reduced pressure in the duct, and a person or object getting on and off the traveling body while maintaining the reduced pressure in the duct. Or loading / unloading device for loading / unloading, traveling body position / speed and duct pressure /
A computer control device for detecting the open / closed state of the door and for safely traveling and operating is provided as means.

[0005]

According to the present invention, the traveling body can travel in the reduced-pressure duct with less air resistance, and at the same time, the fluctuation of the air pressure is reduced, so that the vibration and noise are reduced, and the traveling body is shielded by the duct so that the environment can be protected from the environment. Problems are less likely to occur. The traveling duct more reliably secures a stable air pressure state in the traveling section by the partition door, and maintains traveling safety by the control device. In addition,
Because it is protected by a duct, it is less susceptible to disturbances such as wind and rain.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described below in more detail.

As a basic configuration, a duct (1) for realizing a reduced pressure environment when the traveling body (4) travels is provided, and an exhaust blower (3) for discharging air from the duct to maintain the reduced pressure environment. In addition, an airtight door (2) that opens and closes as necessary to stabilize the air pressure in the traveling section when the traveling body provided in the duct travels is provided. The airtight door (2) is of a sliding type as shown in FIG.
It is opened and closed under the instruction of. The airtight door (2) may be of a destruction type in the event of a collision so that even if the traveling body collides, no serious damage is caused. The track (5) and the linear motor (6) are facilities for running the traveling body (4), and the traveling body may be a track contact type or a floating non-contact type. Since the inside of the traveling body (4) is maintained at the atmospheric pressure, getting on and off the platform (8) is performed by a telescopic airtight getting on / off device (7) such as telescopic, and the airtightness of the duct is maintained. The control device (9) detects the air pressure in the duct by the air pressure sensor (10) and issues an operation instruction to the exhaust blower (3) as required. On the other hand, the position sensor (11) transmits the position / speed information of the running body. Then, the airtight door in the traveling direction is opened, and at the same time, an instruction to close the door that has already passed is issued.

[0008]

According to the present invention, the running resistance of the running body is:
For example, in the case of the magnetic levitation type, the air resistance becomes all at constant speed running on a flat place and is expressed by R = CpV ² (where C is a constant, ρ is the air density, and V is the running speed). Decreases, and R decreases in proportion to this. Therefore, the vehicle can travel with less air resistance than in the atmosphere, and the energy consumed for traveling E = KpV ³ (where K
Is constant), the vehicle can run at a higher speed, and the economy is improved. In addition, since vibration and noise are also proportional to the air density, environmental problems such as vibration and noise are unlikely to occur outside the duct, making construction and operation easier. Comparative examples of the total energy consumption by each method are shown below. However, the track contact running type, the floating non-contact type, the trend curves example on the rate of energy consumption of the vacuum duct flies formula according to the invention, E _T is the total energy consumption,
E _F denotes a consumption energy traveling body floating like. Here, the total running energy consumption can be expressed as follows. _In, E _{T2 =} E F2 + in _{^{K 2 ρ 2 V 2 3,}} E T3 = E F3 + K 3 ρ 3 V 3 3 total traveling energy consumption _{E T2 = E T3, E F2} =
If _{E F3, K 2 ≒ K 3} , ρ 2 V 2 3 ≒ ρ 3 V 3
Assuming that the inside of the ^three ducts is maintained at 0.3 atm, ρ ₃ / ρ ₂
= 0.3, v ₃ / v ₂ ≒ (ρ ₂ / ρ ₃ ) ^1/3 = 1 / (0.3)
^1/3 = 1.49 Therefore, when the total traveling energy consumption is the same, a speed 1.49 times faster than that of the case is possible. That is, if 350 km / hour is assumed as in the example in the above figure, 350 × 1.49 ≒ 520 km / hour.
