Embodiment Construction
[0027] In order to make the purpose and technical solution of the present invention clearer, the present invention is further described in detail below in conjunction with the embodiments and accompanying drawings.
[0028] According to a carbon fiber vacuum pipeline implemented in the present invention, its structure is as follows Figure 1-8 As shown, the outer surface 1.1 of the carbon fiber vacuum pipeline is provided with a vacuum pipeline floor 1.2, the outer surface 1.1 is composed of a skin 10, the inside of the skin 10 is a pipeline skeleton, and the skin 10 and the pipeline skeleton are fixedly connected. Wherein, the skin 10 is made of carbon fiber composite material through winding, and the winding method adopts wet winding, which has low cost and less fiber damage during the manufacturing process, and is widely used in various fields. The use of carbon fiber composite materials to make the skin can not only significantly reduce the weight of the pipeline, but also...

The invention relates to a carbon fiber vacuum pipeline. The carbon fiber vacuum pipeline is characterized in that the carbon fiber vacuum pipeline comprises a pipeline skeleton and a pipeline skin covering the pipeline skeleton. The pipeline skin and the pipeline skeleton are fixedly connected. The pipeline skin is an auxiliary layer formed by winding a carbon fiber composite through a wet method. The pipeline skeleton is of a frame-type pipe structure made of a titanium alloy material. A pipeline floor supporting structure perpendicular to the cross section of the pipeline and extending in the axial direction of the pipeline is arranged in the position, close to the bottom of the circular section of the pipeline, in the pipeline. The upper surface of the pipeline floor supporting structure and the inner wall of the pipeline are both fixedly connected with the pipeline skin. The carbon fiver vacuum pipeline is light, efficient, good in bending-resistant performance, resistant to corrosion, good in airtightness and vibration reduction and noise reduction performance, and safer and more reliable in the service process.
Description
technical field [0001] The invention belongs to the field of vacuum pipeline transportation, in particular to a carbon fiber vacuum pipeline. Background technique [0002] With the formation and rapid development of economic globalization and world integration, people have higher and higher requirements for the convenience of travel and the efficiency of logistics distribution, and the existing transportation methods have been difficult to meet the needs of globalization. Therefore, in order to meet the needs of globalization, it is very necessary to explore a new mode of transportation. [0003] Vacuum pipeline transportation is a promising direction. It can not only improve the efficiency of logistics distribution, but also solve traffic-related problems such as traffic congestion, environmental pollution and safety, and effectively improve the convenience of people's travel. The basic concept of vacuum pipeline transportation is: place the maglev system in a closed vacuu...
