Problems solved by technology

[0002] In order to achieve safe, environmentally friendly, convenient and fast transportation, scientists and technicians from all over the world have been exploring the way of vacuum pipeline transportation to achieve ultra-high-speed transportation. In 1934, German engineer Kemper obtained the world's first patent for maglev trains and proposed to Maglev trains run in vacuum tunnels with a speed of 1800km / h. So far, this technology has not been applied because it is technically difficult and expensive to achieve a high vacuum in the pipeline, and it is not safe. Therefore, Chinese scientific researchers Shen Zhiyun, Zhang Yaoping, Yu Xiaodong and others proposed that in the initial stage, the train can run at a speed of 600-1000km / h in a low-pressure pipeline with a pressure of 10-20kPa, but the existing technical research is only to establish In an environment with air as the medium under different pressure conditions, regardless of the pressure in the pipeline, the influence of air resistance on the ultra-high-speed transport vehicles in the pipeline cannot be ruled out

Embodiment 1

[0010] Embodiment 1: adopt figure 2 The pipeline structure shown is composed of a pipeline (101) and a hydrogen medium (105) at normal pressure. There are wheel-rail vehicles (103), wheel tracks (104), etc. in the pipeline (101), and the pipeline (101) is a sealed structure , to ensure that the outside air cannot enter the inside, the pipeline material can be leak-proof cement or steel plate, engineering plastics, etc., the ratio of the hydrogen medium (105) to the space volume in the pipeline is 80-100%, and the wheel-rail vehicles in the pipeline (101) (103) Operate under the environment of hydrogen medium (105), because the airflow resistance of hydrogen medium (105) to wheel-rail vehicle (103) is about 1 / 14 of the air resistance of the same pressure, so under the same pressure, the light gas pipeline The transportation speed in (101) can be increased, so as to obtain an economical running speed exceeding 1000km / h.

[0011] The characteristic of this scheme is that atmosp...

Embodiment 2

[0012] Embodiment 2: adopt image 3 The pipeline (101) structure shown is composed of pipeline (101) and helium gas (108) at normal pressure. There are magnetic levitation vehicles (106), guide rails (107), etc. in the pipeline (101), and the pipeline (101) is a sealed structure , to ensure that the outside air cannot enter the inside, the pipeline (101) can be made of leak-proof cement, or steel plate, engineering plastics, etc., and the magnetic levitation car body in the pipeline (101) runs under the helium environment, because the helium (108) The airflow resistance of the magnetic levitation vehicle (106) is about 1 / 7 of the air resistance at the same pressure, so under the same pressure, the transportation speed in the light gas pipeline (101) can be significantly increased, thereby obtaining an economical operating speed exceeding 600km / h.

[0013] The characteristic of this scheme is that normal-pressure helium is used as the intermediate medium, and the airflow resist...

Embodiment 3

[0014] Embodiment 3: adopt Figure 4 The pipeline (101) structure shown is composed of pipeline (101), maglev vehicle (106), guide rail (107) and hydrogen medium (105) with a pressure of 10-20kPa. The pipeline (101) is a sealed structure to ensure External air cannot enter the interior, and the material of the pipe (101) can be leak-proof cement, or steel plate, engineering plastic, etc., and the ratio of the hydrogen medium (105) to the space volume in the pipe (101) is 80-100%, and the pipe (101) The maglev car body inside operates under the environment of low hydrogen gas medium (105), because the airflow resistance of the hydrogen gas medium (105) with a pressure of 10-20kPa to the transport vehicle is about 1 / 100 of the air resistance of an atmospheric pressure, so under the same pressure , the transportation speed in the light gas pipeline (101) can be greatly improved, thereby forming an ultra-high operating speed.

[0015] The characteristic of this scheme is that low...

Abstract

The invention provides a light gas pipeline engineering structure, which can implement pipeline superspeed transportation under normal pressure state, and also can implement higher speed transportation under low vacuum or super low vacuum. The technology not only can remarkably reduce the gas-flow resistance of transporting vehicles in the pipeline so as to improve the running speed, but also can save energy consumption under the same technical condition, reduce project construction and operation management cost, and is easy for constructing because the materials of light gas have rich resources.
