Boarding and alighting system of low-vacuum pipeline, running vehicle and transportation system

Abstract

The invention relates to the field of rail transit, in particular to a boarding and alighting system of a low-vacuum pipeline, a running vehicle and a transportation system, the boarding and alightingsystem comprises a vehicle door, a platform door and a sealing device, and the platform door is connected with a low-vacuum pipeline in a sealed mode; the vehicle door is connected with the vehicle in a sealed mode, the vehicle door is arranged in the outer side of the sealing device, the sealing device is connected with the inner side of the vehicle through a sliding mechanism, when the vehicleis parked, the sealing device slides towards the platform door, and the sealing device, the low-vacuum pipeline in the inner side of the platform and the vehicle form a closed space, and the platformdoor and the vehicle door are opened to form a boarding and alighting channel. According to the embodiment of the invention, the sealing device in the vehicle is in sealed butt joint with the platform, the connection time is short, and the transportation efficiency is high; the sealing performance is high, each time of vacuumizing is not needed, and only one vacuum pipeline needs to be vacuumizedregularly; in addition, the sealing technology is mainly applied to vehicles, the technology is simple, and the later maintenance cost is low.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a low-vacuum pipeline ride-and-drop system, a running vehicle and a transportation system. Background technique [0002] In the prior art, any ground vehicle including automobiles, high-speed rail, maglev, etc. is limited by air resistance and aerodynamic noise, and its commercial operating speed should not exceed 400km / h. Speed, at present, it is better to put the vehicle in a vacuum or low vacuum pipeline. Among them, the low-vacuum pipeline transportation system refers to the vehicle system that operates in a sealed pipeline with low atmospheric pressure (10-20KPa) or high vacuum. The system is mainly composed of vehicles, pipelines, tracks, stations, switches, vacuum monitoring, escape systems, etc. . The low-vacuum pipeline transportation system is different from the high-speed rail. Passengers need to overcome the vacuum in the pipeline to enter the vehicle. Ensure the...

Problems solved by technology

[0004] 1. Every time a vehicle enters or leaves the station, it needs to pass through the buffer zone. The air in the buffer zone of the station will enter the vacuum pipeline, causing the air pressure to rise. The air pressure in the pipeline must be kept within the technical requirements through the work of the vacuum pump; while in the buffer zone It takes a long time to vacuumize or fill the area with air, which reduces the transportation efficiency; and consumes a lot of electricity, resulting in energy waste

[0005] 2. The sealing technology of vacuum-sealed doors on the track is complicated, the number of sealed doors is large, and the sealed doors are frequently opened and closed, and the later maintenance costs are high
