Embodiment

[0028] When the transport tool runs in the pipeline, the front end of the transport tool will bear a large air resistance. In the process of continuing to move forward, the air resistance is squeezed by the transport tool to both sides, so that the distance between the front end of the transport tool and the inner wall of the pipeline At the same time, the rear end of the transportation tool will form a low-pressure vacuum area, which will generate a counter-drag force against the forward direction of the transportation tool and form an internal suction force on the inner wall of the pipeline. The pipeline is prone to damage under the action of expansion and suction, which shortens the service life and slows down the running speed of the transportation tool.

[0029] In view of the above problems, this embodiment provides a pipeline air pressure regulating device, which can effectively reduce the negative impact on the transportation vehicle and pipeline caused by the huge air ...

Abstract

The invention relates to the technical field of transportation, in particular to a pipe air pressure regulating device. The pipe air pressure regulating device comprises a pipe and at least one air pressure regulating assembly arranged outside the pipe. The pipe is provided with an inner cavity used for transportation of means of transport. Each air pressure regulating assembly comprises a breather pipe, air inlets and air outlets of the breather pipes communicate with the inner cavity of the pipe, and the breather pipes are used for adjusting the air pressure difference between the front portion and rear portion of the means of transport. The pipe air pressure regulating device reduces the air pressure difference between the front portion and the back portion of the means of transport inthe process of driving in the pipe and reduces the travel resistance of the means of transport; and at the same time, the symmetrical stress caused by the pressure difference between the front portionand the back portion of the means of transport to the pipe wall is reduced, and the pipe is protected. The pipe air pressure regulating device can continuously squeeze the residual air in the pipe out of the pipe through the driving of the means of transport, so that the driving resistance of the means of transport is as low as possible.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a pipeline air pressure regulating device. Background technique [0002] China has launched a maglev train project. The target speed of the train is to surpass the existing jet civil aviation passenger aircraft, and may reach several times the speed of sound. [0003] The maglev train runs in a quasi-vacuum pipeline, and the vacuum degree of the pipeline may be the same as the altitude of 10,000 to 30,000 meters. According to the actual working conditions of the US SR-71 aircraft, it is expected that the train will still be subject to great air resistance. Correspondingly, the air resistance generated at the head of the train during the forward process of the train will also be transformed into a huge expansion reaction force against the pipe wall, which may even cause the pipe to burst; at the same time, the opposite situation will occur at the rear of the train. During ...
