[0021] It should be noted that hydrogen, as a multifunctional chemical substance, has a wide range of applications in real life. During hydrogen transportation, hydrogen pipeline is usually used to transport hydrogen. In order to prevent the collision of hydrogen pipeline during hydrogen transportation and affect normal hydrogen transportation, the device can be used for anti-collision damping treatment. First, arc plate 1 is pushed backward, so that locking piece 5 contacts with hydrogen pipeline. With the backward pushing of arc plate 1, locking block on locking piece 5 will press guide rod. The inclined surface structure of locking block makes it more convenient for arc plate 1 to fit the hydrogen pipeline. At the same time, spring 6 is compressed under stress. Then, arc plate 1 is released. Under the action of spring 6, locking block will pop out backward, so as to lock the hydrogen pipeline.
[0022] When the hydrogen conveying pipeline is impacted by external force, the piston 42 is forced to extrude the cylinder 41 backward, so that the air in the cylinder 41 is discharged to the air valve 43 on both sides, the soft contact surface of the piston 42 can avoid hard friction between the piston 42 and other hydrogen conveying pipelines, thereby protecting the outer wall of the hydrogen conveying pipeline, when the elastic return element between the piston 42 and the air valve 43 is compressed to the limit position, the sliding seat 2 will slide backward, the damping element 7 is pushed backward, when the damping element 7 contacts and continuously rubs with the arc plate 1, at the same time, the L-shaped structure of the damping element 7 can enhance its elasticity, thereby further weakening the impact of external force, the piston 42 and the air valve 43 between the elastic return element makes the piston 42 quickly rebound;
[0023] In the process of conveying hydrogen through the pipeline, it is necessary to maintain the conveying pressure through the compression station, or when the hydrogen conveying pipeline passes through the high temperature area, it may cause the hydrogen or the hydrogen conveying pipeline to generate heat, the temperature in the pipeline rises, the high temperature of the pipeline will cause the hydrogen to expand and the pressure to be too large, which is not conducive to the transportation safety, the hydrogen conveying pipeline needs to be cooled, the heat conduction fin 81 contacts with the outer wall of the hydrogen conveying pipeline and conducts heat to the heat dissipation fin 82, thereby reducing the temperature of the outer wall of the hydrogen conveying pipeline, at the same time, the fan 92 performs air cooling treatment on the heat dissipation fin 82, thereby reducing the temperature of the heat dissipation fin 82, further enhancing the cooling effect.
[0024] The skilled in the art should understand that the above-mentioned embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
