Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 , the vacuum pipeline traffic vehicle running piston effect exhaust vacuum setting, including the pipeline 3 and the vehicle 5 arranged in the pipeline 3, the front end of the vehicle 5 is provided with a piston 2, the piston 2 is fixedly connected to the front end of the vehicle 5 through the connecting rod 4, the piston 2 The shape matches the inner contour of the pipeline 3. Openings are arranged at regular intervals on the wall of the pipeline 3 and a one-way valve 1 is added. The one-way valve 1 can only be opened to the outside of the pipeline 3. During normal operation, the gas can only flow out and cannot inflow.

[0023] The piston 2 and the pipeline 3 have two modes of tight fit and clearance. If the internal contour of the pipeline 3 is regular and t...

Abstract

The invention relates to a vehicle operation piston effect exhaust vacuum pumping arrangement for evacuated tube transportation. The vehicle operation piston effect exhaust vacuum pumping arrangement for the evacuated tube transportation comprises a pipeline and a vehicle which is arranged in the pipeline, wherein a piston is arranged at the front end of the vehicle; the piston is fixedly connected with the front end of the vehicle through a connecting rod; the shape of the piston is matched with the interior contour of the pipeline; openings are formed in the wall of the pipeline at intervals of a certain distance and one-way valves are additionally mounted in the openings; and the one-way valves can be only opened towards outside of the pipeline. As the front end of the vehicle is connected with the piston, gas is exhausted out of the pipeline so that the operation cost is effectively reduced and economic benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of vacuum pipeline transportation, and in particular relates to a piston-effect exhaust and vacuum setting for the operation of vacuum pipeline transportation vehicles. Background technique [0002] Vacuum tube transportation is a new type of transportation system that has not yet been implemented. It is composed of subsystems such as pipelines, magnetic levitation tracks, linear motor drive systems, stations, and vehicles. During operation, the gas in the pipeline is discharged to form a certain vacuum environment, and the magnetic levitation vehicle is driven by the linear motor. Due to the elimination of air resistance and mechanical friction resistance, vehicles can travel at super high speeds in it. [0003] The conventional exhaust and vacuum method is to use a vacuum pump to evacuate the cavity through external equipment such as pipelines and valves to form a vacuum. Accordingly, for vacuum pipeline...
