Description

Technical Field

[0001] The utility model relates to the technical field of gas, in particular to a gas transportation pipeline with an anti-seismic structure. Background Art

[0002] With economic development and rising living standards, the demand for gas has increased significantly, leading to a widespread use of gas pipelines. However, during their use, especially during home renovations or when the surrounding environment is subject to frequent vibrations, the pipeline system is often subject to varying degrees of vibration. These vibrations originate not only from natural movements of the Earth's crust but also from human activities such as construction and traffic. Long-term exposure to vibration can cause serious problems such as fatigue damage, loose joints, and even ruptures in gas pipelines, posing a significant threat to the safe delivery of gas and the safety of people and property.

[0003] Specifically, existing gas pipelines have significant shortcomings in their seismic design. This is primarily due to the lack of a specific shock-absorbing structure in the mounting brackets used to install the pipelines. This results in friction between the mounting brackets and the pipelines when they vibrate, increasing fatigue damage and the risk of rupture, making it difficult to meet actual seismic requirements. This directly compromises the safety and reliability of gas pipelines in vibration environments, increasing maintenance costs and operational risks while also potentially severely impacting the stability and safety of the gas supply. Utility Model Content

[0004] The purpose of the utility model is to provide a gas transportation pipeline with an earthquake-resistant structure, which solves the obvious deficiencies in the earthquake-resistant design of existing gas transportation pipelines in the prior art, mainly reflected in the lack of targeted shock-absorbing structure in the fixing frame used for pipeline installation, which causes friction between the pipeline and the fixing frame when the pipeline as a whole vibrates, increases fatigue damage, and increases the risk of rupture, making it difficult to meet actual earthquake-resistant requirements.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A gas transportation pipeline with an earthquake-resistant structure, comprising a pipeline and an installation sleeve;

[0007] The mounting sleeve includes a semicircular arc sleeve one and a semicircular arc sleeve two. The inner wall of the semicircular arc sleeve one is connected to a plurality of buffer particles. The inner wall of the semicircular arc sleeve two is movably connected to a buffer contact structure. One side of the semicircular arc sleeve two is connected to a mounting plate through a horizontally lateral buffer structure.

[0008] Preferably, both sides of the semicircular arc sleeve 1 and the semicircular arc sleeve 2 are fixedly connected with side plates, and each two adjacent side plates are connected by a plurality of positioning screws.

[0009] Preferably, the buffer contact structure includes a contact strip, one side of the contact strip is connected to a round rod, and the contact strip is made of rubber material.

[0010] Preferably, the buffer particles include contact balls, which are made of rubber material, and one side of the contact balls is fixedly connected to the inner wall of the semicircular arc sleeve.

[0011] Preferably, a movable groove is opened on one side of the mounting plate, and the horizontal transverse buffer structure includes a movable plate slidably connected to the inside of the movable groove, and both sides of the movable plate are elastically connected to the inner wall of the movable groove through a plurality of buffer springs.

[0012] Preferably, the inner wall of the semicircular arc sleeve 2 is provided with two circular holes, the round rod is slidably connected to the inside of the circular hole, and one end of the round rod is elastically connected to the inner wall of the circular hole through a shock-absorbing spring, and the movable plate is connected to the side wall of the semicircular arc sleeve 2 through a connecting bracket.

[0013] The utility model has at least the following beneficial effects:

[0014] The utility model improves the seismic resistance and safety of the pipeline system. First, the buffer particles and buffer contact structure set in the semicircular arc sleeve effectively absorb and disperse the impact force of the pipeline during vibration, directly solving the safety problems of traditional pipelines such as breakage and leakage caused by vibration, and greatly enhancing the durability and reliability of the pipeline. Secondly, the introduction of the horizontal lateral displacement buffer structure gives the installation sleeve the ability to move in the horizontal direction, allowing the pipeline to respond flexibly when facing lateral vibrations, further reducing the risk of pipeline damage caused by rigid connections, thereby ensuring the continuity and stability of gas transportation and providing a solid guarantee for the safe transportation of gas.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Example 1

[0024] See also Figure 1-5 As shown, a gas transportation pipeline with an earthquake-resistant structure in this embodiment includes a pipeline 2 and a mounting sleeve 1;

[0025] Pipeline 2: As the primary carrier of gas transportation, Pipeline 2 is responsible for transporting gas from one location to another. In a seismic-resistant structure, Pipeline 2 is the protected object. The installation sleeve 1 and a series of seismic-resistant designs within it ensure that Pipeline 2 remains stable during vibrations, preventing damage or leakage.

[0026] Mounting sleeve 1 is the core of the seismic structure and consists of semicircular sleeve 101 and semicircular sleeve 2 102. Together, they form a complete annular structure that tightly encases pipe 2. Mounting sleeve 1 primarily provides all-around protection for pipe 2. Its internal buffer particles, contact structure, and horizontal shift buffer effectively absorb and disperse vibration energy, ensuring safe operation of pipe 2.

[0027] Semi-circular sleeve 101: As part of the mounting sleeve 1, the inner wall of semi-circular sleeve 101 is connected to a number of buffer particles. These buffer particles are made of highly elastic, wear-resistant material and provide initial cushioning when the pipe 2 is subjected to vibration, reducing direct collisions between the pipe 2 and the mounting sleeve 1, thereby protecting the pipe 2 from damage.

[0028] Semi-circular arc sleeve 2 102: Compared with semi-circular arc sleeve 1 101, the inner wall of semi-circular arc sleeve 2 102 is movably connected with a buffer contact structure. The buffer contact structure can fit tightly with the outer wall of the pipe 2, further enhancing the anti-seismic effect. When the pipe 2 is vibrated, the buffer contact structure can use its elastic deformation to absorb and disperse the vibration energy, ensuring the stable operation of the pipe 2. At the same time, one side of the semi-circular arc sleeve 2 102 is also connected to the mounting plate 3 through a horizontal transverse buffer structure. This design allows the mounting sleeve 1 to have a certain displacement capacity in the horizontal direction. When the pipe 2 is subjected to lateral vibration, the elastic deformation of the horizontal transverse buffer structure can further absorb and disperse the vibration energy, thereby avoiding damage to the pipe 2 due to the rigid connection.

[0029] Mounting plate 3: Serving as the supporting element of the seismic structure, mounting plate 3 is connected to semicircular sleeve 2 102 via a horizontally shifted buffer structure. Its primary function is to secure and support the entire seismic structure, ensuring its stable installation on pipeline 2 and its effective seismic performance. Mounting plate 3 can also be connected to other fixed structures (such as walls, brackets, etc.) to securely anchor the entire gas pipeline system, enhancing overall system stability and safety.

[0030] The mounting sleeve 1 includes a semicircular arc sleeve 101 and a semicircular arc sleeve 2 102. The inner wall of the semicircular arc sleeve 101 is connected to a plurality of buffer particles. The inner wall of the semicircular arc sleeve 2 102 is movably connected to a buffer contact structure. One side of the semicircular arc sleeve 2 102 is connected to the mounting plate 3 through a horizontally lateral buffer structure.

[0031] Example 2

[0032] See also Figure 1-5 As shown, in this embodiment of a gas transportation pipeline with an earthquake-resistant structure, side panels 6 are fixedly connected to both sides of the semi-circular arc sleeve 101 and the semi-circular arc sleeve 2 102, and each adjacent side panels 6 are connected by a plurality of positioning screws. Specifically, the side panels 6 are fixedly connected to both sides of the semi-circular arc sleeve 101 and the semi-circular arc sleeve 2 102, and each adjacent side panels 6 are connected by a plurality of positioning screws. During installation, the spacing between the semi-circular arc sleeve 101 and the semi-circular arc sleeve 2 102 can be adjusted by tightening or loosening the positioning screws, thereby adapting to pipes 2 of different diameters and ensuring that the installation sleeve 1 can be firmly wrapped around the pipe 2. This design enhances the versatility and stability of the installation sleeve 1, enables the earthquake-resistant structure to function more reliably, and achieves the effect of improving installation convenience and adaptability.

[0033] The buffer particles include contact balls 5, which are made of rubber and have one side fixedly connected to the inner wall of the semicircular sleeve 101. Specifically, by configuring the buffer particles to include contact balls 5, which are made of rubber and have one side fixedly connected to the inner wall of the semicircular sleeve 101, the contact balls 5 act as point contact elements, providing multi-point buffering when the pipeline 2 is subjected to vibrations through the elasticity of the rubber material and its spherical structure. This design makes the buffering effect more uniform and effective, avoids damage caused by localized stress concentration, and achieves the effect of improving the buffering effect and extending the service life.

[0034] Example 3

[0035] See also Figure 1-5 As shown, in this embodiment, a gas transportation pipeline with a seismic-resistant structure comprises a buffer contact structure comprising a contact strip 4, one side of which is connected to a round rod 11, and the contact strip 4 is made of rubber. Specifically, by virtue of the buffer contact structure comprising the contact strip 4, one side of which is connected to a round rod 11, and the contact strip 4 being made of rubber, when the pipeline 2 is subjected to vibration, the contact strip 4 can utilize its elasticity to closely adhere to the outer wall of the pipeline 2 and provide a buffer. At the same time, the round rod 11 can adjust the position of the contact strip 4 to a certain extent to accommodate slight displacements of the pipeline 2. This design further enhances the buffering effect of the seismic-resistant structure, reduces direct collisions between the pipeline 2 and the mounting sleeve 1, and thereby achieves the effect of improving seismic resistance and protecting the pipeline.

[0036] A movable groove 10 is provided on one side of the mounting plate 3, and a horizontal transverse buffer structure includes a movable plate 7 that is slidably connected to the interior of the movable groove 10. Both sides of the movable plate 7 are elastically connected to the inner wall of the movable groove 10 via a number of buffer springs 9. Specifically, a movable groove 10 is provided on one side of the mounting plate 3, and a horizontal transverse buffer structure includes a movable plate 7 that is slidably connected to the interior of the movable groove 10. Both sides of the movable plate 7 are elastically connected to the inner wall of the movable groove 10 via a number of buffer springs 9. When the pipeline 2 is subjected to lateral vibration, the movable plate 7 can slide within the movable groove 10 and absorb and disperse the vibration energy through the elastic deformation of the buffer springs 9. This design allows the mounting sleeve 1 to have a certain displacement capacity in the horizontal direction, avoiding pipeline damage caused by rigid connection, and achieving the effect of improving lateral seismic resistance and protecting the pipeline.

[0037] The inner wall of the second semi-circular sleeve 102 is provided with two circular holes 13, and the round rod 11 is slidably connected to the inside of the circular holes 13. One end of the round rod 11 is elastically connected to the inner wall of the circular hole 13 via a shock-absorbing spring 12. The movable plate 7 is connected to the side wall of the second semi-circular sleeve 102 via a connecting bracket 8. Specifically, the inner wall of the second semi-circular sleeve 102 is provided with two circular holes 13, and the round rod 11 is slidably connected to the inside of the circular holes 13. One end of the round rod 11 is elastically connected to the inner wall of the circular hole 13 via a shock-absorbing spring 12. The movable plate 7 is connected to the side wall of the second semi-circular sleeve 102 via a connecting bracket 8. The combination of the round rod 11 and the shock-absorbing spring 12 provides additional cushioning and support for the contact strip 4, allowing the contact strip 4 to better fit the outer wall of the pipe 2 and provide a stable cushioning effect. At the same time, the movable plate 7 is connected to the side wall of the second semi-circular sleeve 102 via the connecting bracket 8, ensuring a stable connection between the horizontal lateral movement buffer structure and the mounting sleeve 1. This design further enhances the overall stability and reliability of the earthquake-resistant structure, achieving the effect of improving earthquake resistance and ensuring structural safety.

[0038] This program has the following working process:

[0039] The pipeline system mainly includes a pipeline 2 and an installation sleeve 1. During installation, first adjust the distance between the semi-circular arc sleeve 1 101 and the semi-circular arc sleeve 2 102 by tightening or loosening the positioning screw according to the diameter of the pipeline 2, so that the two can be combined to form a complete circular ring structure and tightly wrap the pipeline 2. At this time, the contact ball 5 on the inner wall of the semi-circular arc sleeve 101 acts as a point contact element and makes initial contact with the outer wall of the pipeline 2, providing a basic buffering effect. At the same time, the contact strip 4 in the buffering contact structure on the inner wall of the semi-circular arc sleeve 2 102, using the elasticity of its rubber material, fits tightly with the outer wall of the pipeline 2 to form a further buffer layer. The sliding connection between the round rod 11 and the round hole 13, and the elastic support of the shock-absorbing spring 12, provide the contact strip 4 with additional buffering and adjustment capabilities, so that it can better adapt to the slight displacement and vibration of the pipeline 2.

[0040] When the pipe 2 is vibrated, the entire seismic structure begins to work together. First, the contact ball 5 uses the elasticity of its rubber material and spherical structure to provide buffering at multiple points, initially absorbing and dispersing the vibration energy. Subsequently, the contact strip 4, supported by the round rod 11 and the shock-absorbing spring 12, further absorbs and disperses the vibration energy while maintaining a close fit with the outer wall of the pipe 2 to avoid direct collision. In addition, when the pipe 2 is subjected to lateral vibration, the movable plate 7 slides in the movable groove 10 and absorbs and disperses the vibration energy through the elastic deformation of the buffer spring 9. This design allows the mounting sleeve 1 to have a certain displacement capacity in the horizontal direction, avoiding damage to the pipeline caused by rigid connection.

[0041] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention.
