For example, they can be fixed connections, detachable connections, or integral connections; they can be mechanical connections or electrical connections; they can be direct connections, indirect connections through an intermediate medium, or internal connections between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Reference Figure 1-4The utility model provides an embodiment of an impact-resistant pipeline for hydrogen transportation, comprising an upper fixed plate 1, the top of the upper fixed plate 1 is movably connected with a fixing nut 2, which is convenient for the subsequent installation and fixation of the upper fixed plate 1 and the lower fixed plate 3, the bottom of the upper fixed plate 1 is movably connected with the lower fixed plate 3, the top of the lower fixed plate 3 is provided with a placement cavity 4, for placing the delivery pipe 5, and the delivery pipe 5 is arranged inside the placement cavity 4, and the bottom of the lower fixed plate 3 is fixedly connected with a support seat 6 to keep the device as a whole stable with the ground, a fixing hole 7 is provided on the top of the support seat 6, a mounting hole 8 is provided on the top of the upper fixed plate 1, and a protective pad 9 is fixedly connected to the inner wall of the placement cavity 4 to reduce impact force and improve protection capability, an anti-static coating 10 is provided on the outer wall of the anti-static coating 10, an anti-freeze layer 11 is sleeved on the outer wall of the anti-freeze layer 11, a heat insulation layer 12 is sleeved on the outer wall of the heat insulation layer 12, and a corrosion-resistant layer 13 is sleeved on the outer wall of the upper fixed plate 1

[0028] Specifically, the antistatic coating 10 is composed of acrylic material, the antifreeze layer 11 is composed of natural rubber material, and the thermal insulation layer 12 is composed of extruded polystyrene board material, which reduces the impact of external high and low temperatures, static electricity, corrosion, etc. on the conveying pipe 5 and extends its service life.

[0029] Specifically, a placement cavity 4 is provided on one side of the upper fixing plate 1 and the lower fixing plate 3. The placement cavity 4 has a semicircular shape. There are five placement cavities 4 in each group to keep the delivery pipes 5 stably and neatly placed.

[0030] Specifically, a fixing hole 7 is provided on the top of the upper fixing plate 1 and the lower fixing plate 3. The inner diameter of the fixing hole 7 is slightly larger than the fixing nut 2. The fixing nut 2 cooperates with the nut to facilitate subsequent disassembly, maintenance or installation by the user.

[0031] Specifically, the protective pad 9 is made of a buffer rubber material and is fixed to the placement cavity 4 through a fixing nut 2 to reduce the influence of external impact energy on the delivery pipe 5 .

[0032] Specifically, the waterproof coating 14 is composed of polyurethane waterproof material. The waterproof coating 14 is only located on the outer walls of the upper fixing plate 1 and the lower fixing plate 3 to reduce the corrosion of the upper fixing plate 1 and the lower fixing plate 3 by rainwater.

[0033] Working principle: When in use, place the support base 6 on the ground, and then insert the expansion screw into the fixing hole 7 to keep the lower fixed plate 3 fixed to the ground position to avoid subsequent displacement of the delivery pipe 5 and cause breakage, and then place the delivery pipe 5 in the top placement cavity 4 of the lower fixed plate 3, and then dock the upper fixed plate 1 with the lower fixed plate 3 and use the fixing nut 2 to insert into the mounting hole 8 to fix it. When it rains outside, the waterproof coating 14 on the outer wall of the upper fixed plate 1 and the lower fixed plate 3 effectively reduces the corrosion of rainwater. When impacted by the outside world, the upper fixed plate 1 and the lower fixed plate 3 effectively block the impact object to prevent it from directly colliding with the delivery pipe 5 and causing the delivery pipe 5 to break. At the same time, the protective pad 9 absorbs and disperses the impact force to reduce the impact on the delivery pipe 5. At the same time, the antifreeze layer 11 and the thermal insulation layer 12 effectively reduce the impact of high and low temperatures on hydrogen transportation, so that the hydrogen temperature remains stable at all times to avoid expansion and explosion.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
