Problems solved by technology

From the above information, it can be seen that the operation of the existing train operation system is greatly affected by the air. In order to overcome the resistance of the air, a large amount of energy consumption is required. Air resistance is the main obstacle to improving the speed of the train.
In addition, since the train runs in an open natural space, the noise during the train operation also has a great impact on the life and normal rest of the residents along the railway.
The exhaust gas generated during the operation of the train is also very polluting to the environment. Due to the current open operation mode, the railway line is generally dirty. The sundries discarded by passengers and the waste water discharged by the train directly affect the surrounding environment, and it is also prone to train pollution. Accidents with pedestrians or other vehicles

Embodiment Construction

[0012] Example. As shown in Figure 1, a sub-vacuum high-speed train operating system, the system is to set up a closed tunnel on the running path between the station and the station, and maintain a sub-vacuum state below 10Kpa in the closed tunnel to reduce the stress in the train operation. Air resistance, reducing the power required for the train to overcome air resistance, and the impact of noise during train operation on the outside world. There are car covers at both ends of the closed tunnel. When the train leaves the station, first open the pressure-holding door between the station and the car cover. The train enters the car cover from the station, then closes the pressure-preserving door between the station and the car cover, and then opens The pressure-holding door between the car cover and the closed tunnel, the train enters the closed tunnel; when the train enters the station, it is contrary to the above process, and its purpose is to prevent the vacuum degree in th...

Abstract

The subvacuum high speed train system has sealed tunnels set between stations and maintained in subvacuum state below 50 KPa to reduce resistance to the train and noise. The system includes closed tunnels, intermittently set vacuum pumps, train jackets on ends of tunnels, pressure maintaining doors, and tracks. The present invention has greatly reduced power consumption for pulling train, raised train speed, reduced noise, reduced environment friendly and reduced railway accidents. The present invention is suitable for electric locomotive system and magnetic suspension train system.

Description

technical field [0001] The invention relates to a train running system, in particular to a sub-vacuum high-speed train running system. Background technique [0002] At present, there are mainly two types of operating systems for high-speed trains: one is the wheel-rail type, and the other is the magnetic levitation type. These two kinds of train running systems operate in an open natural space. During the running process, the power of the train is mainly used to overcome the air resistance of the train at high speed, and the power required to overcome the frictional resistance of the train itself But very few. According to data, when the train speed is 360 km / h, 95% of the output power of the wheel-rail train is used to overcome air resistance, and only another 5 / % is used to overcome the system friction resistance of the train itself. The output power of the maglev train is almost all used to overcome air resistance. As can be seen from the above data, the existing train...
