[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0019] Embodiment: refer to Figures 1-4 The mining ventilation pipeline with the supporting structure comprises a plurality of skeletons 1 arranged at equal intervals, plastic canvases 2 connected between the skeletons 1, and a pipe body of the ventilation pipeline composed of the skeletons 1 and the plastic canvases 2. One end of the ventilation pipeline is provided with a first interface 3, and the other end of the ventilation pipeline is provided with a second interface 4. The plurality of skeletons 1 arranged at equal intervals provide a supporting frame for the ventilation pipeline, thereby enhancing the structural strength of the pipeline and enabling the pipeline to withstand certain external force without being easily deformed or damaged. The plastic canvases 2 are connected between the skeletons 1 to form a ventilation passage and have a certain flexibility, thereby adapting to the complex terrain of the mining environment. The first interface 3 and the second interface 4 facilitate the connection of the ventilation pipeline with other ventilation equipment or pipelines to construct a complete ventilation system. The first interface 3 is in the shape of a wide-mouthed horn, and metal buckles are arranged at equal intervals at the outer wall interface of the first interface 3. The clamping seats 5 and the clamping blocks 6 of the metal buckles are arranged at equal intervals and alternately distributed. The wide-mouthed horn-shaped first interface 3 is conducive to guiding the smooth entry of airflow into the ventilation pipeline and reducing airflow resistance. The metal buckles of the outer wall are alternately distributed with the clamping seats 5 and the clamping blocks 6. The edge positions corresponding to the circular outlet are folded, so that the clamping seats 5 and the clamping blocks 6 are buckled with each other. With the increase in the number of buckles, the circular outlet gradually shrinks to realize the closing. The advantage of this structure is that the closing is relatively firm and can maintain a fixed closing state. The connecting disc 7 is fixedly connected at the interface of the second interface 4. A plurality of connecting holes are arranged at equal intervals on the connecting disc 7 along the shaft side. The pipe body of the ventilation pipeline is symmetrically provided with the fixing discs 8 at both ends. The connecting disc 7 and the connecting holes thereon provide multiple choices for the connection of the second interface 4 with other equipment or pipelines, thereby enhancing the flexibility and reliability of the connection. The fixing discs 8 symmetrically arranged at both ends of the pipe body provide stable fixing points for the subsequent installation of the supporting structure, which plays an important role in improving the overall stability of the ventilation pipeline.

[0021] Working principle: when the utility model is used, before the ventilation pipeline is installed, first, the metal buckle of the first interface 3 is used to tightly buckle the clamping seat 5 and the buckle protruding block 6 on the corresponding interface of other ventilation equipment or pipeline, when the ventilation system starts, the external air enters the ventilation pipeline from the first interface 3 under the action of the fan, since the first interface 3 is in the shape of a wide-mouthed horn, the airflow can be smoothly guided to enter, the airflow resistance is reduced, the air entering the pipeline flows along the pipe body composed of a plurality of frameworks 1 and plastic canvas 2, the framework 1 provides a stable support structure for the ventilation pipeline, and ensures that the pipe body will not deform or be damaged due to airflow impact or external pressure; the plastic canvas 2 forms a ventilation passage, and the flexibility thereof can adapt to the complex terrain in the mining environment, in the ventilation process, the equidistantly arranged support screw 12 between the fixed disc 8 cooperates with the fixed nut 10 and the anti-skid gasket 11 to further enhance the overall structural strength of the ventilation pipeline, the fixed nut 10 is screwed on the support screw 12 and abuts against the outer wall of the fixed disc 8, the anti-skid gasket 11 increases the friction between the two, prevents the loosening of the support screw 12, and ensures the stable operation of the ventilation pipeline, when the ventilation pipeline needs to be stored, the pipe body is first stored, at this time, the two protection sleeves 9 can be tightly inserted with each other through the inserting grooves thereon, ingeniously utilize the space, greatly reduce the space occupation during storage, and facilitate the transportation and storage of the ventilation pipeline.
