Pipeline transportation can not only transport energy gases such as natural gas over long distances and in large volumes, but also transport various materials within the station. Now, various types of pressurized gas pipelines of various pressure levels are very common in the industrial system. During the operation of pressurized gas pipelines, when there are certain differences in the physical parameters, physicochemical properties, operating conditions, and operating environment of the transport medium, there are certain differences in the leakage diffusion rate of the pressurized pipeline medium, the consequences of leakage accidents, and the scope of impact. Related studies have explored its changing laws through various means such as calculation and simulation, but experimental simulation and testing are the most intuitive and reliable research methods, which help to overcome the limitations of the model itself and obtain more real and accurate data.

Figures 9 and 10As shown, the processing mechanism 3 includes a track block 31, the outer side of the track block 31 is slidably connected to a processing frame 32, the inner side of the processing frame 32 is rotatably connected to a connecting shaft 33, the outer side of the connecting shaft 33 is fixedly connected to a friction column 34, the outer side of the friction column 34 is provided with a square groove 35, the outer side of the processing frame 32 is fixedly connected to a second motor 36 on one side close to the connecting shaft 33, the outer side of the connecting shaft 33 is fixedly connected to the output end of the second motor 36, and the outer side of the processing frame 32 is fixedly connected to a cleaning mechanism 37 on one side. The processing frame 32 slides on the track block 31 close to the pipeline, and the second motor 36 drives the friction column 34 to rotate, so as to rub the outside of the pipeline, so as to detect the hardness of the outside of the pipeline, so as to facilitate observation of whether the pipeline is leaking. By providing a square groove 35, the contact area is increased by providing a groove, the friction performance is improved, and the friction grinding effect is further improved, so that it is convenient to check the pipeline surface. When grinding, there may be impurities on the pipeline surface. The impurities on the surface are cleaned to avoid affecting the observation effect. The cleaning mechanism 37 rubs with the outside of the friction column 34 to clean the impurities on the outside of the friction column 34, reduce the adsorption of impurities on the surface of the component, and avoid affecting the subsequent friction effect.

[0032] The cleaning mechanism 37 includes a cleaning frame 371, a third electric push rod 372 is fixedly connected to the side of the cleaning frame 371 close to the friction column 34, and a rotating column 373 is rotatably connected to the side of the third electric push rod 372 away from the cleaning frame 371. An annular groove 374 is provided on the outer side of the rotating column 373. The rotating column 373 is controlled by the third electric push rod 372 to fit the outer side of the friction column 34. When the friction column 34 rotates, it is frictionally adapted with the rotating column 373. The friction column 34 is rubbed by the rotating column 373, thereby achieving the effect of cleaning impurities of the components, reducing the adsorption of impurities on the surface of the components, and preventing the friction effect from being affected. Secondly, by providing the annular groove 374, the friction area is increased by providing the groove, and the cleaning effect is improved. At the same time, the rotating column 373 can be controlled by the third electric push rod 372 to be away from the friction column 34, thereby reducing excessive friction between components and reducing the surface wear of the components, thereby extending the service life of the components.

[0033] When in use, the staff places the pipeline inside the fixing mechanism 19, and clamps and fixes the pipeline by the fixing mechanism 19, so as to improve the stability of the pipeline and avoid shaking during subsequent operations, thereby affecting the subsequent operation efficiency. After the pipeline is fixed by the fixing mechanism 19, one side of the pipeline rod 15 is connected to the water pipe, and then the first electric push rod 13 controls the pipeline rod 15 to move inside the pipeline, and sprays from the outside of the spraying mechanism 17 by the water pressure, so as to spray the inner wall of the pipeline, so as to facilitate the detection of whether the pipeline is leaking. The spraying mechanism 17 is impacted by the water pressure and rotates on the outside of the connecting block 14, so as to increase the water spraying area and the fineness of the water spraying, and improve the penetration effect of the water flow, so as to facilitate more intuitive detection of the pipeline. A rotating mechanism 177 is arranged inside the spraying mechanism 17, and the rotating mechanism 177 is driven to rotate by the first motor 178 to achieve cleaning. The impurities on the inner wall of the spraying mechanism 17 are prevented from settling, thereby affecting the water flow effect and preventing blockage. When the fixing mechanism 19 clamps the pipeline, the fixing mechanism 19 slides on the bar slide rail 18 according to the length of the pipeline, so as to adjust the clamping distance, thereby facilitating the improvement of the clamping force. When the fixing mechanism 19 slides on the bar slide rail 18, in order to avoid the derailment of the fixing mechanism 19, the fixing mechanism 19 is restricted from excessive sliding by the limiting mechanism 2, thereby achieving the sliding effect of the braking component. A processing mechanism 3 is provided on the top of the composite base 11, and the processing mechanism 3 is used to grind and rub the pipeline surface to detect the hardness and toughness of the pipeline surface, so as to detect whether the pipeline is leaking. When the processing mechanism 3 rubs the pipeline, there may be certain impurities on the pipeline surface, thereby hindering the observation of the pipeline surface condition. When the processing mechanism 3 is polished, the impurities are cleaned to avoid affecting the observation effect.
