Description

Technical Field

[0001] This utility model relates to the technical field of seismic protective sleeves for energy pipelines, and in particular to a high-strength seismic protective sleeve. Background Technology

[0002] Energy pipelines are widely used in the energy industry, including oil, natural gas, and heat transmission. High-strength seismic-resistant protective sleeves for energy pipelines are crucial facilities for ensuring the safety of energy transmission. Made of high-strength, high-toughness composite materials and featuring a special buffer and energy-absorbing structure design, they effectively disperse stress and absorb energy under severe vibrations such as earthquakes, reducing pipeline displacement and deformation caused by vibration. Simultaneously, they possess excellent corrosion resistance and weather resistance, extending pipeline service life and building a solid safety barrier for the stable transmission of energy sources such as oil and natural gas.

[0003] Traditional pipeline protection measures rely on a single seismic mechanism, often using rubber or springs, which is insufficient to cope with complex vibrations. They also suffer from poor structural stability and adaptability, are prone to loosening and displacement, cannot adapt to pipeline changes, have limited protective functions, and the outer layer materials are difficult to balance impact resistance and corrosion resistance, and lack heat dissipation design. Under strong vibrations, pipelines are prone to problems such as loose joints, pipeline deformation, and even rupture, which can lead to energy leaks and safety accidents. To address these issues, we propose a high-strength seismic protective sleeve. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength shock-resistant protective sleeve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength shock-resistant protective sleeve, comprising a protective mechanism and a support mechanism disposed on its outer side. The protective mechanism includes an inner buffer sleeve, on the inner wall of which a spiral protrusion is fixedly installed. Multiple sets of mounting kits are fixedly installed on the outer wall of the inner buffer sleeve. Each set of mounting kits is connected to a sliding member through a sliding groove. The sliding member is connected to a buffer spring through a flexible pressure-resistant member. Therefore, the inner buffer sleeve is connected to the outer protective sleeve through a sealing member.

[0006] As a preferred embodiment, the sliding groove is formed inside the mounting kit, and the sliding member is slidably connected inside the sliding groove.

[0007] As a preferred embodiment, the flexible anti-pressure component is fixedly installed on the upper end of the sliding component, one end of the buffer spring is fixedly installed on the inner side of the flexible anti-pressure component, and the other end of the buffer spring is fixedly installed inside the sliding groove.

[0008] As a preferred embodiment, the sealing element is fixedly installed at both ends of the outer protective sleeve, the inner end of the sealing element is fixedly installed at the outer end of the inner buffer sleeve, the outer protective sleeve is made of high-strength alloy steel, the surface of the outer protective sleeve is coated with an anti-corrosion coating, and the outer wall of the outer protective sleeve has heat dissipation holes.

[0009] As a preferred embodiment, the support mechanism includes a connecting frame that is snapped onto the outer wall of the outer protective sleeve.

[0010] As a preferred embodiment, a reinforcing rod is fixedly installed in the middle of the connecting frame, and mounting grooves are passed through the bottom of both ends of the connecting frame. A spring damper is fixedly installed inside the mounting groove, and a mounting base is fixedly installed at the bottom of the spring damper.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the designed protective mechanism, the inner buffer sleeve and the spiral protrusion can fit tightly against the pipe surface, which not only enhances the friction to prevent the protective sleeve from shifting, but also uses the flexible material to absorb the small vibrations generated by the pipe itself. When the pipe is subjected to vibration and impact, the sliding part slides in the sliding groove, the buffer spring is compressed to absorb energy, and the flexible anti-pressure part avoids the rigid collision of the spring, effectively attenuating vibrations of different frequencies and reducing the risk of pipe joints becoming loose or deformed due to vibration. The outer protective sleeve is made of high-strength alloy steel with an anti-corrosion coating, which has both high strength impact resistance and excellent corrosion resistance, and can resist external mechanical impact and harsh environmental corrosion.

[0013] 2. Through the set support mechanism, the connecting frame is firmly attached to the outer protective sleeve by snap-fit, the middle reinforcing rod effectively disperses the external pressure and improves the overall rigidity of the protective sleeve, and the spring dampers in the mounting slots at both ends form a secondary buffer structure with the mounting base. When the protective sleeve is subjected to ground vibration or external impact, the spring dampers are compressed and deformed synchronously to absorb and dissipate vibration energy. Compared with the protective sleeve without a support structure, this further ensures the stability of pipeline operation. Attached Figure Description

[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 the appendix Figure 1 - Appendix Figure 6 A high-strength shock-resistant protective sleeve includes a protective mechanism 1 and a support mechanism 2 disposed on its outer side. The protective mechanism 1 includes an inner buffer sleeve 101. A spiral protrusion 102 is fixedly installed on the inner wall of the inner buffer sleeve 101. Multiple sets of mounting kits 103 are fixedly installed on the outer wall of the inner buffer sleeve 101. Each set of mounting kits 103 is connected to a sliding member 106 through a sliding groove 104. The sliding member 106 is connected to a buffer spring 107 through a flexible pressure-resistant member 105. Therefore, the inner buffer sleeve 101 is connected to an outer protective sleeve 108 through a sealing member 110.

[0024] The sliding groove 104 is formed inside the mounting kit 103, and the slider 106 is slidably connected inside the sliding groove 104.

[0025] The flexible anti-compression component 105 is fixedly installed on the upper end of the sliding component 106, one end of the buffer spring 107 is fixedly installed on the inner side of the flexible anti-compression component 105, and the other end of the buffer spring 107 is fixedly installed inside the sliding groove 104.

[0026] The sliding connection design between the mounting kit 103 and the sliding member 106 allows the protective sleeve to automatically adjust the buffering force according to the vibration amplitude of the pipeline. When the vibration intensity changes, the sliding member 106 adaptively moves within the sliding groove 104, and in conjunction with the elastic deformation of the buffer spring 107, the buffering performance is adjusted in real time to adapt to the seismic resistance requirements of energy pipelines under different working conditions. Compared with a fixed structure protective sleeve, it can better cope with complex and variable vibration environments.

[0027] The sealing element 110 is fixedly installed at both ends of the outer protective sleeve 108. The inner end of the sealing element 110 is fixedly installed at the outer end of the inner buffer sleeve 101. The outer protective sleeve 108 is made of high-strength alloy steel. The surface of the outer protective sleeve 108 is coated with an anti-corrosion coating 111. The outer wall of the outer protective sleeve 108 has heat dissipation holes 109.

[0028] The design of the heat dissipation hole 109 allows the heat generated during pipeline operation to be dissipated in a timely manner, preventing heat accumulation from affecting the performance of the pipeline and protective sleeve. The seal 110 connects the inner buffer sleeve 101 and the outer protective sleeve 108, effectively preventing external moisture and dust from entering, providing three-dimensional protection against dust, water, and corrosion for the energy pipeline, and extending the service life of the pipeline. The tight fit of the spiral protrusion 102 with the pipeline, combined with the stable connection of the inner and outer layers by the seal 110, ensures the overall structural stability of the protective sleeve. The modular design of each component, such as the standard assembly structure of the sliding groove 104 and the sliding element 106, facilitates installation and disassembly. Damaged components can be quickly replaced during later maintenance, reducing maintenance costs and time costs, and improving maintenance efficiency.

[0029] Specifically, the inner buffer sleeve 101 and the spiral protrusion 102 fit tightly against the pipe surface, which not only enhances friction to prevent the protective sleeve from shifting, but also absorbs the small vibrations generated by the pipe's operation using the flexible material. The middle layer forms a dynamic buffer system consisting of a sliding groove 104, a sliding element 106, a flexible anti-pressure element 105, and a buffer spring 107. When the pipe is subjected to vibration impact, the sliding element 106 slides in the sliding groove 104, the buffer spring 107 is compressed to absorb energy, and the flexible anti-pressure element 105 avoids rigid collisions with the spring, effectively attenuating vibrations of different frequencies and reducing the risk of pipe joint loosening and deformation caused by vibration. The outer protective sleeve 108 is made of high-strength alloy steel and is equipped with an anti-corrosion coating 111, which has both high strength impact resistance and excellent corrosion resistance, and can resist external mechanical impacts and harsh environmental corrosion.

[0030] Please see the appendix Figure 1 and attached Figure 7 The support mechanism 2 includes a connecting frame 201, which is snapped onto the outer wall of the outer protective sleeve 108.

[0031] A reinforcing rod 202 is fixedly installed in the middle of the connecting frame 201. Mounting grooves 203 are passed through the bottom of both ends of the connecting frame 201. A spring damper 204 is fixedly installed inside the mounting groove 203. A mounting base 205 is fixedly installed at the bottom of the spring damper 204.

[0032] The spring damper 204 can be replaced with different damping coefficient models according to different installation environments such as ground flatness and vibration source intensity, so as to realize the parameterized adjustment of the support mechanism 2. The mounting base 205 supports multiple installation methods such as bolt fixing and magnetic fixing, and is suitable for diverse scenarios such as industrial pipe supports and ground foundations, significantly improving the applicability of the protective sleeve in complex working conditions.

[0033] Specifically, the connecting frame 201 is securely attached to the outer protective sleeve 108 by a snap-fit ​​method, the middle reinforcing rod 202 effectively disperses external pressure and improves the overall rigidity of the protective sleeve, and the spring dampers 204 in the mounting grooves 203 at both ends form a secondary buffer structure with the mounting base 205. When the protective sleeve is subjected to ground vibration or external impact, the spring dampers 204 are compressed and deformed synchronously to absorb and dissipate vibration energy. Compared with a protective sleeve without a support structure, this further ensures the stability of pipeline operation.

[0034] The working principle of this utility model is as follows: This utility model is a high-strength shock-resistant protective sleeve. First, align the spiral protrusion 102 on the inner wall of the inner buffer sleeve 101 with the energy pipeline, and rotate the inner buffer sleeve 101 to make it tightly fit the pipeline surface. Then, fix the outer protective sleeve 108 to the outer end of the inner buffer sleeve 101 through the sealing element 110, ensuring that the sealing element 110 completely covers the seam between the inner and outer layers to prevent moisture and dust from entering. Next, clamp the connecting bracket 201 to the outer wall of the outer protective sleeve 108, install the spring damper 204 in the mounting grooves 203 at both ends of the connecting bracket 201, and fix the mounting base 205 to the bottom of the spring damper 204. Depending on the installation environment, select bolt fixing or magnetic attraction method to firmly install the mounting base 205 on the ground, bracket, or other foundation. When the energy pipeline vibrates during operation, the spiral protrusions 102 on the inner wall of the inner buffer sleeve 101 are in close contact with the pipeline surface to absorb minor vibrations. If strong vibrations or impacts occur, the sliding member 106 slides in the sliding groove 104, causing the buffer spring 107 to compress and deform. The flexible anti-pressure member 105 prevents the spring from rigidly colliding, absorbing and dissipating vibration energy through deformation. When the protective sleeve is subjected to ground vibrations or external mechanical impacts, the spring damper 204 of the support mechanism 2 is compressed synchronously, converting the vibration energy into the elastic potential energy of the spring and the heat energy of the damper. The reinforcing rod 202 in the middle of the connecting frame 201 disperses external pressure, preventing the outer protective sleeve 108 from deforming due to uneven force, achieving secondary buffering and providing double protection for stable pipeline operation. The heat generated by the pipeline operation is dissipated to the outside through the heat dissipation holes 109 of the outer protective sleeve 108. The high-strength alloy steel outer protective sleeve 108, combined with the anti-corrosion coating 111, resists external impacts and environmental erosion, while the sealing member 110 isolates moisture and dust, maintaining a stable internal environment for the protective sleeve.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
