Problems solved by technology
[0003] Existing high-speed trains and maglev trains are also equipped with equipment cabins. The equipment cabins are equipped with multiple curved surface hatches, and there are many equipment hatches. Since the vehicles operate in a normal pressure environment, some of the hatches do not need to be sealed. Although there are sealing tapes around some of the mouth covers, they can only play a role of dust prevention and cannot meet the sealing load requirements of a standard atmospheric pressure.
In addition, the sealing of the curved surface cover in a vacuum environment has great technical difficulties, and the cost of improving its vacuum adaptability is relatively high, and the development risk is high, and the economic and time costs are high.

The invention relates to the technical field of vacuum pipeline trains, and discloses a sealing equipment cabin for a vacuum pipeline train and the vacuum pipeline train. The sealing equipment cabin comprises a cover body, a cabin body, a sealing body and a fastening device, when the sealing equipment cabin is closed, the sealing body fills the part between the contact surfaces of the cover body and the cabin body, and the fastening device is used for connecting the cover body and the cabin body in a fastening mode and further pressing the sealing body to achieve sealing. Wherein the sealing body is of a soft hollow pipe structure and is filled with gas with preset pressure. A simple and reliable end face sealing mode is adopted, and the difficulty of large-curved-surface sealing and the complexity of multi-curved-surface sealing are avoided.
Description
technical field [0001] The invention relates to the technical field of vacuum pipeline trains, in particular to a sealed equipment cabin for vacuum pipeline trains and the vacuum pipeline train. Background technique [0002] The vacuum tube train has the characteristics of ultra-high speed, low energy consumption, low noise, and low pollution. It operates in a low-vacuum environment. Working conditions, the operating environment is harsher than the existing high-speed rail and maglev trains. In addition, vehicle operation requires a large number of supporting equipment to provide functions such as power supply in the vehicle, life environment protection in the vehicle, refrigeration, and water circulation. In order to effectively improve the passenger carrying capacity of the vehicle, it is necessary to centrally install the supporting equipment in the equipment compartment at the lower part of the vehicle body. [0003] Existing high-speed trains and maglev trains are als...
