Description

Technical Field

[0001] This utility model belongs to the field of hydrogen transmission pipe technology, specifically relating to a hydrogen transmission pipe structure for storing and releasing hydrogen. Background Technology

[0002] Hydrogen storage involves transporting hydrogen from tank trucks to hydrogen storage tanks at hydrogen storage stations. This transport requires the use of hydrogen pipelines, and the existing hydrogen pipelines are used to transport hydrogen from tank trucks to hydrogen storage tanks at hydrogen storage stations.

[0003] Existing hydrogen transport pipes are prone to generating high internal pressure during hydrogen storage and release. Furthermore, the exposed outer surface of these pipes makes wear protection difficult. Sometimes, the exposed outer surface comes into contact with the ground, causing friction damage during pulling. Prolonged use and severe wear, coupled with internal pressure, can lead to safety hazards and compromise the ease of wear protection for the outer surface of the hydrogen transport pipe during storage and release. Therefore, this invention proposes a new structure for hydrogen transport pipes used for hydrogen storage and release. Utility Model Content

[0004] The purpose of this utility model is to provide a hydrogen transport pipe structure for storing and releasing hydrogen, so as to solve the problems mentioned in the background art. When existing hydrogen transport pipes are used for storing and releasing hydrogen, the internal pressure of the hydrogen transport pipe is prone to be large. At the same time, the outer surface of the hydrogen transport pipe is directly exposed to the outside world, which is not conducive to wear-resistant protection. Sometimes, the outer surface of the hydrogen transport pipe is exposed to the outside world and comes into contact with the ground, which causes friction damage when pulled. After long-term use, severe friction damage and internal pressure can cause danger in use and reduce safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydrogen transport pipe structure for storing hydrogen, comprising a hydrogen transport pipe, both ends of which are provided with mounting heads, the ends of which are fitted with sealing gaskets, the outer surface of the hydrogen transport pipe being provided with a wear-resistant protection mechanism, the wear-resistant protection mechanism including a wear-resistant protection component disposed on the outer surface of the hydrogen transport pipe, the wear-resistant protection component having a deformation buffer component disposed inside, and the inner surface of the hydrogen transport pipe being coated with a graphene coating.

[0006] The outer surface of the mounting head is provided with a reinforcing mounting mechanism, which includes a fixing component disposed at the edge of the mounting head, a locking component disposed at the end of the fixing component, and a rotational reinforcing component disposed on the outer surface of the fixing component.

[0007] Preferably, the wear-resistant protection component includes an outer wear-resistant protective sleeve integrally formed on the outer surface of the hydrogen transport pipeline, and wear-resistant protrusions are equidistantly arranged on the outer surface of the outer wear-resistant protective sleeve.

[0008] Preferably, the surface of the wear-resistant raised strip is arc-shaped, and the wear-resistant raised strip and the outer wear-resistant protective sleeve are an integral structure.

[0009] Preferably, the deformation buffer assembly includes a deformation cavity formed inside the wear-resistant protrusion, the cross-section of which is semi-circular.

[0010] Preferably, the fixing component includes a fixing block integrally disposed on the outer surface of the mounting head, and the end of the fixing block is formed with a groove.

[0011] Preferably, the engaging assembly includes a locking rod mounted in the end groove of the fixing block via a pin, and the top end of the locking rod is provided with an anti-slip hook.

[0012] Preferably, the rotational reinforcement assembly includes an external thread structure formed on the surface of the fixing block, and an internal thread cover is rotatably mounted on the outer surface of the fixing block through the external thread structure. The surface of the internal thread cover is provided with an engagement groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By designing a wear-resistant protection mechanism, when the outer surface of the hydrogen pipeline is in use and in contact with the ground, the wear-resistant protrusions and the outer wear-resistant protective sleeve provide wear protection. This mechanism also facilitates tensile protection under tension. When the outer surface of the hydrogen pipeline is under pressure, the deformation cavity inside the wear-resistant protrusions causes deformation, buffering the outer surface and making it less prone to damage under pressure. This enhances safety and improves the convenience and safety of wear protection for the outer surface of the hydrogen pipeline during storage, installation, and transportation.

[0015] By designing a graphene coating, when hydrogen is transported inside the hydrogen pipeline, the hydrogen comes into contact with the graphene coating on the inner surface. The graphene coating effectively prevents hydrogen from entering the interior of the hydrogen pipeline and causing damage, thus extending the service life of the hydrogen pipeline.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a hydrogen transport pipe structure for storing hydrogen, including a hydrogen transport pipe 101, with mounting heads 102 at both ends of the hydrogen transport pipe 101, and sealing gaskets 103 engaged at the ends of the mounting heads 102. The inner surface of the hydrogen transport pipe 101 is coated with a graphene coating surface 1014. When hydrogen is transported inside the hydrogen transport pipe 101, the hydrogen comes into contact with the graphene coating surface 1014 on the inner surface. The graphene coating surface 1014 effectively prevents hydrogen from entering the interior of the hydrogen transport pipe 101 and causing damage, thereby extending the service life of the hydrogen transport pipe 101.

[0024] The outer surface of the hydrogen pipeline 101 is provided with a wear-resistant protection mechanism. The wear-resistant protection mechanism includes a wear-resistant protection component installed on the outer surface of the hydrogen pipeline 101. The wear-resistant protection component has a deformation buffer component installed inside. When the hydrogen pipeline 101 is transporting hydrogen, the wear-resistant protection mechanism can effectively protect the outer surface of the hydrogen pipeline 101 from wear, making it less prone to damage and ensuring safe transportation.

[0025] To facilitate wear protection of the outer surface of the hydrogen pipeline 101 using a wear-resistant protection component, in this embodiment, preferably, the wear-resistant protection component includes an outer wear-resistant protective sleeve 1012 integrally formed on the outer surface of the hydrogen pipeline 101. The outer surface of the outer wear-resistant protective sleeve 1012 is integrally provided with wear-resistant protrusions 1011 at equal intervals. The surface of the wear-resistant protrusions 1011 is arc-shaped. When the hydrogen pipeline 101 is in use, the wear-resistant protrusions 1011 and the outer wear-resistant protective sleeve 1012 can provide wear protection for the outer surface of the hydrogen pipeline 101 and effectively provide tensile protection.

[0026] In order to facilitate both wear-resistant protection and buffering protection of the wear-resistant protrusion 1011 through the deformation buffer assembly, in this embodiment, preferably, the deformation buffer assembly includes a deformation cavity 1013 formed inside the wear-resistant protrusion 1011. The cross-section of the deformation cavity 1013 is semi-circular, which can provide wear-resistant protection for the outer surface of the wear-resistant protrusion 1011, and when the outer surface is under pressure, the deformation cavity 1013 deforms to buffer and protect the wear-resistant protrusion 1011, thus facilitating buffering protection.

[0027] The outer surface of the mounting head 102 is provided with a reinforcing mounting mechanism. The reinforcing mounting mechanism includes a fixing component located at the edge of the mounting head 102, a locking component at the end of the fixing component, and a rotating reinforcing component on the outer surface of the fixing component. After the mounting head 102 is installed with the hydrogen storage tank and the tank truck structure, the reinforcing mounting mechanism can strengthen and fix the mounting head 102, making it less likely to loosen under stress.

[0028] To facilitate installation using a fixing component, in this embodiment, preferably, the fixing component includes a fixing block 1021 integrally disposed on the outer surface of the mounting head 102. The end of the fixing block 1021 has a groove, which allows the locking rod 1022 to be adjusted within the groove at the end of the fixing block 1021, facilitating adjustment and locking installation.

[0029] In order to facilitate the secure engagement of the mounting head 102 with the interface surface by means of the engagement assembly, in this embodiment, preferably, the engagement assembly includes a locking rod 1022 installed in the end groove of the fixing block 1021 by means of a pin. The top end of the locking rod 1022 is provided with an anti-slip hook, which can move and adjust the locking rod 1022 to engage the end hook with the surface of the external interface, thus facilitating the engagement and installation.

[0030] To facilitate the reinforcement and engagement of the locking rod 1022 via the rotational reinforcement assembly, in this embodiment, preferably, the rotational reinforcement assembly includes an external thread structure 1025 formed on the surface of the fixing block 1021. An internal thread cover 1023 is rotatably mounted on the outer surface of the fixing block 1021 via the external thread structure 1025. The surface of the internal thread cover 1023 has a meshing groove 1024, which can be engaged with the hook at the end of the locking rod 1022 on the surface of the external interface. A wrench engages inside the meshing groove 1024, causing the internal thread cover 1023 to rotate on the outer surface of the fixing block 1021 until the internal thread cover 1023 is pressed tightly onto the outer surface of the fixing block 1021 for reinforcement and engagement.

[0031] The working principle and usage process of this utility model: When using this hydrogen storage and transportation pipe structure, the first step is to install it. One end of the hydrogen transportation pipe 101, the installation head 102, can be connected to the interface of the hydrogen storage tank on the tanker truck, and the other end of the hydrogen transportation pipe 101, the installation head 102, can be connected to the interface of the hydrogen storage tank in the hydrogen storage station, so as to facilitate the transportation of hydrogen from the tanker truck to the hydrogen storage tank in the hydrogen storage station.

[0032] Then, when the mounting head 102 is installed, and the mounting head 102 is sealed inside the interface between the tank truck and the hydrogen storage tank by the sealing gasket 103, the clamping rod 1022 is moved to engage the hook at the end of the clamping rod 1022 on the outer surface of the interface. Then, the inner thread cover 1023 is rotated on the outer surface of the fixing block 1021 through the external thread structure 1025 until the inner surface of the inner thread cover 1023 is pressed against the surface of the clamping rod 1022, which facilitates the engagement and reinforcement after installation. This strengthens the installation of the mounting head 102 during installation, making it less prone to loosening and instability when the mounting head 102 is subjected to pressure during hydrogen storage and release, and improving the reinforcement and fixation of the mounting head 102 during hydrogen storage and release.

[0033] Finally, when the hydrogen pipeline is in use, and the outer surface of the hydrogen pipeline 101 is exposed to the outside and in contact with the ground, the wear-resistant protrusions 1011 and the outer wear-resistant protective sleeve 1012 provide wear protection to the ground and facilitate tensile protection when subjected to tension. When the outer surface of the hydrogen pipeline 101 is under pressure, the deformation cavity 1013 inside the wear-resistant protrusions 1011 causes deformation to buffer and protect the outer surface, making it less prone to damage under pressure and safer to use. This improves the convenience and safety of wear protection for the outer surface of the hydrogen pipeline 101 during hydrogen storage, installation, transportation, and use.

[0034] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
