Description

Technical Field

[0001] This invention belongs to the field of pipeline safety transportation technology, and specifically relates to a special energy transportation pipeline for high-altitude areas. Background Technology

[0002] With increasing global emphasis on environmental protection, efforts are being accelerated to reduce pollution from traditional energy sources, while also promoting the production and use of various clean energy sources, especially hydrogen energy. Traditional hydrogen production primarily relies on natural gas steam reforming, naphtha, oil refineries, petroleum reforming from other industrial waste gases, and partial oxidation of coal and other hydrocarbons. Small quantities can also be obtained through water electrolysis and other sources. However, these methods are not clean enough, and the hydrogen production process often generates pollution, hence the term "grey hydrogen." With technological advancements, solar thermal cracking for hydrogen production is now available. However, timely transportation and storage are crucial after hydrogen production. Because hydrogen is a small molecule, traditional pipelines are prone to "hydrogen embrittlement" during long-term transport. Therefore, many inventors have focused on developing pipelines specifically designed for this purpose. Currently, high-altitude regions, especially Xinjiang and Inner Mongolia, have longer and more efficient sunlight, requiring more stringent pipeline requirements than those in more arid environments. However, the specific performance requirements of thinner hydrogen transport pipelines used in harsh environments—high altitudes, intense ultraviolet radiation, windy sandstorms, and gravel—cannot be met simultaneously. The existing technology still has the following drawbacks in its use: For example, RSOC disc hydrogen production equipment in high-altitude areas requires water to be transported upwards to supply hydrogen production. After production, the prepared material needs to be transported to underground equipment. However, the environment in such areas is often accompanied by extreme climate conditions, stronger sunlight, high salinity and acidity in some areas, huge temperature differences, low pressure, and lack of oxygen, which are all extreme environmental challenges. These problems can lead to the breakage of the thin tubes that transport energy, a reduction in service life, or even safety accidents such as hydrogen leakage. 2. For example, RSOC disc hydrogen production equipment in high-altitude areas is quite tall and requires very long pipelines. Too many pipelines or pipelines that are too thick and heavy will cause great problems for actual implementation, construction and long-term use. In addition, a section of the installation needs to go deep into the underground equipment. Such a construction environment makes the construction technology, equipment and subsequent operation and maintenance methods more difficult.

[0003] Therefore, there is an urgent need for a dedicated energy transmission pipeline technology for high-altitude areas to address the shortcomings of existing technologies.

[0004] In view of this, we propose a special energy transmission pipeline device for high-altitude areas to solve the existing problems. Summary of the Invention

[0005] The purpose of this invention is to provide a dedicated energy transmission pipeline for high-altitude areas to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the first aspect of the present invention adopts the following technical solution: A special energy transmission pipeline for high-altitude areas includes a coaxial outer pipe, a middle pipe, an inner pipe, and two end connectors. A plurality of first elastic elements are fixedly disposed between the inner wall of the outer pipe and the outer wall of the middle pipe. These first elastic elements are evenly spaced and arranged in a circular array around the outer periphery of the middle pipe. A plurality of second elastic elements are fixedly disposed between the inner wall of the middle pipe and the outer wall of the inner pipe. These second elastic elements are evenly spaced and arranged in a circular array around the outer periphery of the inner pipe. One end of each end connector has the same outer diameter as the outer pipe, while the outer diameter of the other end is less than two-thirds of the outer diameter of the outer pipe. The two ends of the end connector are curved and constricted as a whole.

[0007] Preferably, the intermediate tube includes an outer fitting ring and an inner fitting ring. The inner circumferential surface of the outer fitting ring has a first fitting portion with alternating concave and convex shapes, and the outer circumferential surface of the inner fitting ring has a second fitting portion with alternating concave and convex shapes. The outer fitting ring is fitted and abutted to the second fitting portion of the inner fitting ring through the first fitting portion.

[0008] Preferably, steel wires are fixedly provided inside the protrusions of both the first fitting portion and the second fitting portion.

[0009] Preferably, the cross-section of the first elastic element is S-shaped and a sealing tube coaxial with the outer tube is fixed in the middle. The sealing tube, together with the first elastic elements and the outer fitting ring, forms a plurality of oxygen delivery channels. The sealing tube, together with the first elastic elements and the outer tube, forms a plurality of redundant channels.

[0010] Preferably, the cross-section of the second elastic element is S-shaped and the cross-sectional shape is opposite to that of the first elastic element. Several second elastic elements are arranged together with the inner ring and the inner tube to form several pure water delivery channels.

[0011] Preferably, one end of the end connector is fixedly connected to the outer tube, the intermediate tube, and the inner tube. The interior of the end connector has a first cylindrical flow channel communicating with the oxygen delivery channel and a second cylindrical flow channel communicating with the pure water delivery channel. Both the first and second cylindrical flow channels are tapered. The other end of the first cylindrical flow channel is shorter than the opening length of the second cylindrical flow channel and both are in a closed state. The exterior of the end connector has at least one oxygen delivery pipe interface communicating with the other end of the first cylindrical flow channel and at least one pure water delivery pipe interface communicating with the other end of the second cylindrical flow channel.

[0012] Preferably, both the outer and inner interlocking rings are fixedly connected to the middle of the end face of the end body connector.

[0013] Preferably, a plurality of nylon threads are fixedly arranged inside the outer tube along the axial direction, and the plurality of nylon threads are distributed in a circumferential array at equal intervals around the axis of the outer tube.

[0014] Preferably, an annular groove is provided at the port cross-section of the end connector.

[0015] Preferably, an ethylene-vinyl alcohol copolymer material pipe is fixedly sleeved inside the inner tube, and a high-purity montmorillonite material layer is filled between the outer surface of the ethylene-vinyl alcohol copolymer pipe and the inner surface of the inner tube.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The technical solution of this invention, through the interlocking of the outer and inner interlocking rings, and the combination of the outer pipe body, inner pipe body, first elastic element, and second elastic element, creates a three-layer structure for the pipeline, with an internal interlocking structure. This design ensures structural stability within the pipeline while allowing for minor deformation and misalignment of the interlocking gaps during high-intensity torsion and deformation. When the external force disappears, the deformed area returns to its original shape. This design increases torsional resistance, prevents internal pipeline damage, extends service life, and improves fatigue resistance. Furthermore, the first and second elastic elements are both designed in an S-shape, allowing the pipeline to form a partition and provide channel space. The S-shape also guides the pipe during torsion. Simultaneously, by setting opposite S-shaped trends, the internal force direction differs after torsional tension. The internal support is achieved through the support of the first and second elastic elements, resulting in opposite force directions acting on the outer and inner interlocking rings, causing overall deformation and thus ensuring the pipeline's stability. The structure will not twist, crack, or be damaged; several redundant channels can accommodate minor deformations of the outer pipe and sealing pipe, ensuring that the pipe will not be damaged after being subjected to stress caused by external mechanical forces, temperature differences, or air pressure changes; in addition, during use, the oxygen delivery channel and the first cylindrical flow channel are located in the outer part of the pipe, which is used to deliver oxygen downwards. Since oxygen and air are poor conductors of heat relative to the pipe body, the influence of external temperature on the pipe interior can be greatly reduced, forming the first line of safety protection for the pipe interior, while also achieving the effects of delivering hydrogen and resisting torsion and tension; by setting the other end of the first cylindrical flow channel to be shorter than the opening length of the second cylindrical flow channel, the interfaces of the oxygen delivery pipe and the pure water delivery pipe can be smoothly connected to the first and second cylindrical flow channels, and at least one interface of the oxygen delivery pipe and the pure water delivery pipe can be opened on the outer periphery of the end joint, thereby improving the connection interface and increasing the delivery efficiency; The technical solution of this invention, through a three-layer structural design, enables the pipeline to simultaneously deliver energy to both ends, reducing the number of pipelines and improving installation convenience. The composite design of a single pipeline provides multiple channels while enhancing wear resistance, flexural flexibility, and thermal insulation. Furthermore, the design of two identical end-body connectors at both ends allows for easy connection to either end during installation, further improving ease of use. The superior flexibility of the nylon thread, coupled with the greater torsion and tension on the outer periphery of the pipeline, provides protection from the tension of the nylon thread, resulting in improved pipeline toughness, reduced damage, longer service life, and reduced production costs. Finally, the interlaced steel wires at the protruding parts of the first and second fitting sections allow for varying distances from the axis, facilitating pipeline handling, installation, and maintenance. During installation, the pipe exhibits strong tensile strength during pulling or twisting, and also strong resistance to torsion during significant twisting. Especially after installation, when the pipe is in a tilted or even vertically suspended state for extended periods, the internal steel wire effectively and significantly prevents damage and tensile breakage due to prolonged suspension. In use, the pipe, with its ethylene-vinyl alcohol copolymer material as a barrier layer, significantly reduces hydrogen permeability, meeting the stringent requirements of harsh environments at high altitudes. During operation, the first layer of the ethylene-vinyl alcohol copolymer pipe provides a high degree of hydrogen barrier, and the layered "maze effect" of the high-purity montmorillonite material creates a tortuous "maze effect," greatly extending the diffusion path of hydrogen molecules and preventing hydrogen leakage and embrittlement. This allows it to adapt to the harsh requirements of high altitudes, demonstrating exceptional adaptability. Attached Figure Description

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0025] This embodiment provides a dedicated energy transmission pipeline for high-altitude areas proposed in this invention, such as... Figures 1 to 6 As shown, the pipe includes a coaxial outer tube 1, a middle tube 2, an inner tube 3, and two end connectors 4. In use, the three-layer structure design provides a passageway while improving wear resistance, flexural flexibility, and thermal insulation. The two identical end connectors 4 at both ends allow for easy connection to either end during installation, increasing ease of installation. Several first elastic elements 5 are fixedly arranged between the inner wall of the outer tube 1 and the outer wall of the middle tube 2. These first elastic elements 5 are evenly spaced and arranged in a circular array around the outer circumference of the middle tube 2. In use, the first elastic elements 5 are preferably made of elastic rubber. The evenly spaced, circumferentially spaced first elastic elements 5 provide stable support between the outer tube 1 and the outer fitting ring 201. The sealing tube 10 connects the several first elastic elements 5. The pipe is divided into two parts, forming two spaces. The inner space can transport energy materials, while the outer space can form redundant space after pipe deformation, increasing resistance to deformation. Several second elastic elements 6 are fixedly installed between the inner wall of the middle pipe 2 and the outer wall of the inner pipe 3. The second elastic elements 6 are evenly spaced and arranged in a circular array on the outer periphery of the inner pipe 3. In use, both the first elastic element 5 and the second elastic element 6 are made of elastic rubber material. In addition, the interior of the first elastic element 5 and the second elastic element 6 can be set with a built-in memory metal structure to increase their support and recovery effect. One end of the end connector 4 has the same outer diameter as the outer pipe 1, while the outer diameter of the other end is less than two-thirds of the outer diameter of the outer pipe 1. The two ends of the end connector 4 are curved and constricted. In use, by reducing the size of the ends, the pipe can be easily installed in various environments.

[0026] like Figures 3 to 6As shown, the intermediate pipe body 2 further includes an outer fitting ring 201 and an inner fitting ring 202. The inner circumferential surface of the outer fitting ring 201 has a first fitting part 7 with alternating concave and convex sections, and the outer circumferential surface of the inner fitting ring 202 has a second fitting part 8 with alternating concave and convex sections. The outer fitting ring 201 is fitted and abutted to the second fitting part 8 of the inner fitting ring 202 through the first fitting part 7. In use, the fitting arrangement of the outer fitting ring 201 and the inner fitting ring 202 enables the internal structure of the pipe to maintain stability while allowing for slight deformation and misalignment of the fitting gap during high torsion and deformation. When the external force disappears, the deformed part will return to its original state. This design increases the torsional resistance, prevents internal damage to the pipe, increases the service life, and improves fatigue resistance.

[0027] like Figures 4 to 5 As shown, furthermore, steel wires 9 are fixedly installed inside the protrusions of both the first fitting part 7 and the second fitting part 8. In use, by setting the interlaced steel wires 9 in the protruding parts of the first fitting part 7 and the second fitting part 8, the steel wires 9 can be distributed far from and close to the axis. When the pipeline is pulled or twisted during transportation, installation, or after installation, the interior of the pipeline can have a strong tensile effect. When there is a large-amplitude twisting, it can also have a strong anti-twisting effect. Especially when the pipeline is installed, it will be in an inclined or even vertically suspended state for a long time. The internal steel wires 9 can effectively and significantly prevent the pipeline from being damaged or broken by tensile stress due to long-term suspension.

[0028] like Figures 3 to 6 As shown, furthermore, the cross-section of the first elastic element 5 is generally S-shaped, and a sealing tube 10 coaxial with the outer tube 1 is fixed in the middle. In use, the S-shaped design allows the pipe to form a partition and have channel space, and the S-shape can guide the pipe when it twists. The sealing tube 10, together with several first elastic elements 5 and the outer fitting ring 201, forms several oxygen delivery channels 11. Several redundant channels 12 are formed between the sealing tube 10, several first elastic elements 5 and the outer tube 1. In use, the several redundant channels 12 It can accommodate the slight deformation of the outer pipe body 1 and the sealing pipe 10, ensuring that the pipe will not be damaged after being subjected to external mechanical force, temperature difference, air pressure change, etc. In addition, during use, the oxygen delivery channel 11 and the first cylindrical flow channel 14 are located in the outer part of the pipe. They are used to deliver oxygen downwards. Since oxygen and air are poor conductors of heat relative to the pipe body, they can greatly reduce the influence of the external temperature of the pipe on the inside of the pipe, forming the first safety protection for the inside of the pipe, while also achieving the effects of delivering hydrogen and resisting torsion and tension.

[0029] like Figures 4 to 5As shown, the cross-section of the second elastic element 6 is S-shaped and the cross-sectional shape is opposite to that of the first elastic element 5. In use, the S-shaped design allows the pipe to form a partition and have channel space, and the S-shape can guide the pipe when it is twisted. At the same time, by setting the opposite direction of the S-shaped trend, the internal force direction of the pipe is different after being subjected to torsional tension. The internal support will be supported by the first elastic element 5 and the second elastic element 6, so that the force direction is opposite. Then it acts on the outer fitting ring 201 and the inner fitting ring 202, causing the overall deformation, thereby ensuring that the pipe structure will not twist, crack or be damaged. Several second elastic elements 6, inner fitting ring 202 and inner pipe body 3 are arranged to form several pure water delivery channels 13. In use, the formation of pure water delivery channels 13 allows water resources to be delivered to the other end of the pipe to supply external equipment for hydrogen production.

[0030] like Figure 6 As shown, further, one end of the end connector 4 is fixedly connected to the outer pipe 1, the middle pipe 2, and the inner pipe 3. The end connector 4 has a first cylindrical flow channel 14 connected to the oxygen delivery channel 11 and a second cylindrical flow channel 15 connected to the pure water delivery channel 13. In use, the pure water delivery channel 13 and the second cylindrical flow channel 15 are used to deliver water upwards. Located in the inner structure of the pipeline, this design allows the water in the second cylindrical flow channel 15 to form an insulating layer, reducing the impact of the large temperature difference outside the pipeline at high altitudes on the temperature of the hydrogen in the innermost pipe 3, further reducing the risk caused by temperature. Both the first cylindrical flow channel 14 and the second cylindrical flow channel 15 are tapered, making the pipeline easier to install and more adaptable. The other end of the first cylindrical flow channel 14 is shorter than the opening of the second cylindrical flow channel 15. The lengths are all sealed. In use, by setting the other end of the first cylindrical flow channel 14 to be shorter than the opening length of the second cylindrical flow channel 15, the interfaces of the oxygen delivery pipe interface 16 and the pure water delivery pipe interface 17 can be smoothly connected to the first cylindrical flow channel 14 and the second cylindrical flow channel 15. At least one interface of the oxygen delivery pipe interface 16 and the pure water delivery pipe interface 17 is located on the outer periphery of the end body connector 4, thereby improving the connection interface and increasing the delivery efficiency. The exterior of the end body connector 4 has at least one oxygen delivery pipe interface 16 connected to the other end of the first cylindrical flow channel 14 and at least one pure water delivery pipe interface 17 connected to the other end of the second cylindrical flow channel 15. In use, by setting at least one oxygen delivery pipe interface 16 and a pure water delivery pipe interface 17, the delivery efficiency of the pipeline is significantly increased.

[0031] like Figure 6As shown, the outer fitting ring 201 and the inner fitting ring 202 are both fixedly connected to the middle of the end face of the end body connector 4. In use, the outer fitting ring 201 and the inner fitting ring 202 are connected to the end body connector 4 while there is a gap between them. This design can maintain the stability and tightness of the structure, and also make the mechanism have the effect of resisting torsion and tension. In addition, the space between the inner and outer pipe bodies 1 and the inner pipe body 3 is divided into two parts.

[0032] As shown in the figure Figures 4 to 5 As shown, further, a number of nylon threads 101 are fixedly arranged inside the outer tube 1 along the axial direction. The number of nylon threads 101 are distributed in a circumferential array with equal intervals around the axis of the outer tube 1. In use, the nylon threads 101 have better flexibility, and the degree of torsion and tension of the outer periphery of the pipe is greater. This makes the pipe protected by the tension of the nylon threads 101 around the periphery, thereby achieving better pipe toughness, making it less prone to damage, improving service life, and saving production costs for enterprises.

[0033] like Figure 6 As shown, further, an annular groove 18 is provided at the port section of the end connector 4; when in use, the annular groove 18 is provided so that when the pipe is connected to external equipment, a sealing element can be added, thereby enabling a tighter connection and achieving high standards and preventing leakage at the interface.

[0034] like Figure 4 As shown, the inner tube 3 is further fitted with an ethylene-vinyl alcohol copolymer pipe 19. When in use, by setting the pipe with ethylene-vinyl alcohol copolymer material as a barrier layer, the hydrogen permeability can be greatly reduced, meeting the strict requirements of the harsh environment in high-altitude areas.

[0035] like Figure 4 As shown, furthermore, a high-purity montmorillonite material layer 20 is filled between the outer surface of the ethylene-vinyl alcohol copolymer pipe 19 and the inner surface of the inner pipe body 3. In use, the high hydrogen barrier provided by the first layer of the ethylene-vinyl alcohol copolymer pipe 19, combined with the layered "layered" structure of the high-purity montmorillonite material layer 20, forms a tortuous "maze effect," which greatly extends the diffusion path of hydrogen molecules, thereby preventing hydrogen leakage and hydrogen embrittlement, and can meet the stringent requirements of high altitudes.

[0036] The working principle of the technical solution for a dedicated energy transmission pipeline in high-altitude areas, as described in the embodiment, is as follows: This invention, by designing two identical end connectors 4 at both ends, allows the pipeline to be connected to either end in any direction during installation and use, increasing installation convenience. After installation, water enters from the pure water delivery pipe interface 17 at the lower end of the pipeline, gradually flowing into the second cylindrical flow channel 15 and then into the pure water delivery channel 13. The water is then sent to the photothermal pyrolysis reactor of the disc-type hydrogen production equipment at the upper end of the pipeline. After the water is pyrolyzed by the photothermal pyrolysis reactor, the generated oxygen enters from the oxygen delivery pipe interface 16 of the pipeline into the end connector 4, then through the first cylindrical flow channel 14 into the oxygen delivery channel 11, and is transported to the lower end of the pipeline. The first cylindrical flow channel 14 enters the end connector 4, and then flows from the oxygen delivery pipe interface 16 at the lower end to the external equipment. At the same time, the hydrogen gas after photothermal decomposition flows from the ethylene-vinyl alcohol copolymer pipe 19 at the upper end of the pipe into the external equipment at the lower end of the pipe, thereby realizing the simultaneous delivery of water to the upper end of the pipe and oxygen and hydrogen to the lower end of the pipe. The technical solution of the present invention, through the interlocking arrangement of the outer interlocking ring 201 and the inner interlocking ring 202, and the combination of the outer pipe body 1, the inner pipe body 3, the first elastic element 5, and the second elastic element 6, makes the pipe as a whole a three-layer structure with an internal interlocking structure. Thus, the internal structure of the pipe can maintain the stability of the structure and achieve high torsion. During deformation, the interlocking seam undergoes slight deformation and misalignment. When the external force disappears, the deformed part returns to its original shape. This design increases torsional resistance, prevents internal pipe damage, increases service life, and improves fatigue resistance. Furthermore, both the first elastic element 5 and the second elastic element 6 are designed in an S-shape, allowing the pipe to form a partition and provide channel space. The S-shape also guides the pipe during torsion. Simultaneously, by setting opposite S-shaped trends, the internal force direction differs after the pipe is subjected to torsional tension. The internal support is achieved by the first elastic element 5 and the second elastic element 6, resulting in opposite force directions, which then act on the outer interlocking ring 201 and the inner interlocking ring 201. On 02, the overall deformation is caused, thereby ensuring that the pipeline structure will not twist, crack, or be damaged; several redundant channels 12 can accommodate the small deformation of the outer pipe body 1 and the sealing pipe 10, ensuring that the pipeline will not be damaged after being subjected to external mechanical force, temperature difference, air pressure change, etc.; in addition, when in use, the oxygen delivery channel 11 and the first cylindrical flow channel 14 are located in the outer part of the pipeline, which is used to deliver oxygen downward. Since oxygen and air are poor conductors of heat relative to the pipeline body, they can greatly reduce the influence of the external temperature of the pipeline on the inside of the pipeline, forming the first safety protection for the inside of the pipeline, while also achieving the effects of delivering hydrogen and resisting torsion and tension.

[0037] The above specific embodiments are merely several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
