Description
Technical Field
[0001] This utility model relates to the field of oil transportation, and more specifically, to a pipeline protection device. Background Technology
[0002] Oil transportation often uses pipelines, making effective protection of pipelines in critical and vulnerable areas crucial. Traditionally, this involves adding high-strength materials and flexible buffer structures to these areas to enhance the overall protection of the pipeline.
[0003] This protective measure can effectively mitigate the mechanical stress caused by external impacts, geological deformation, or accidental collisions, preventing pipeline rupture or severe deformation, thereby ensuring the safe operation and long-term use of pipelines in complex environments and improving the stability and reliability of the oil transportation system.
[0004] However, existing pipeline protection devices still have the following problems:
[0005] (1) Traditional pipeline anti-collision structures or simple elastic gaskets, such a single energy absorption method leads to insufficient impact absorption capacity; (2) The protection device needs to be replaced as a whole after partial damage, which is inconvenient to maintain and not conducive to regular inspection. At the same time, it is difficult to adapt to different length ranges and needs.
[0006] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0007] In view of the problems in the related technologies, this utility model proposes a pipeline protection device to overcome the above-mentioned technical problems existing in the existing related technologies.
[0008] Therefore, the specific technical solution adopted by this utility model is as follows:
[0009] A pipeline protection device includes: symmetrically arranged semi-circular outer shells, with an outer protective component disposed inside the semi-circular outer shells for providing an outer impact-resistant buffering effect; an inner protective component located inside the semi-circular outer shells and inside the outer protective component for providing an inner impact-resistant buffering effect; connecting parts located on both sides of the semi-circular outer shells for connecting two adjacent semi-circular outer shells; an auxiliary support mechanism located at the bottom of the semi-circular outer shells for improving the stability of the semi-circular outer shells; and positioning holes and positioning pins located at both ends of the semi-circular outer shells for positioning and connecting two semi-circular outer shells arranged along the axis of the oil transport pipeline.
[0010] Furthermore, to enhance the impact buffering capacity of the entire device, the outer protective component includes a first arc-shaped groove disposed within a semi-circular outer shell, with several mounting brackets inside the first arc-shaped groove, each mounting bracket housing a buffer body; the inner protective component includes a second arc-shaped groove disposed within the semi-circular outer shell and located inside the outer protective component, with a corrugated elastic plate disposed within the second arc-shaped groove; limit grooves are provided at both ends of the second arc-shaped groove, and limit blocks are provided at both ends of the corrugated elastic plate within the limit grooves.
[0011] Furthermore, in order to achieve a high-strength, detachable connection between adjacent semi-circular shells, the connecting part includes connecting plates disposed on both sides of the semi-circular shells, and two adjacent connecting plates are connected by fasteners.
[0012] Furthermore, to enhance the stability and anti-overturning capability of the semi-circular shell when encasing the oil transport pipeline, the auxiliary support mechanism includes a U-shaped connecting block located at the bottom of the semi-circular shell, with a connecting plate situated inside the U-shaped connecting block. A fixing block is located at the bottom of the U-shaped connecting block, and a ground-pile type support column is installed inside the fixing block. Bolts are screwed into the side wall of the U-shaped connecting block, with the ends of the bolts abutting against the side wall of the connecting plate inside the U-shaped connecting block.
[0013] The beneficial effects of this utility model are as follows:

[0026] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0027] According to an embodiment of the present invention, a protective device for pipelines is provided.
[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, the pipeline protection device according to an embodiment of the present invention includes: symmetrically arranged semi-circular outer shells 1, with an outer protective component 2 disposed inside the semi-circular outer shells 1 for providing an outer anti-collision buffer effect; an inner protective component 3 located inside the semi-circular outer shells 1 and inside the outer protective component 2 for providing an inner anti-collision buffer effect; a connecting part 4 located on both sides of the semi-circular outer shells 1 for connecting two adjacent semi-circular outer shells 1 so that the two semi-circular outer shells 1 can surround the outside of the pipeline; an auxiliary support mechanism 5 located at the bottom of the semi-circular outer shells 1 for improving the stability of the semi-circular outer shells 1; and positioning holes 6 and positioning pins 7 located at both ends of the semi-circular outer shells 1 for positioning and connecting the two semi-circular outer shells 1 arranged along the axis of the oil transport pipeline.
[0029] By means of the above solution, this utility model, through the coordinated configuration of the outer protective component 2 and the inner protective component 3, and the combination of the modular connection part 4 and the stable auxiliary support mechanism 5, not only achieves efficient buffering and anti-collision protection for oil transportation pipelines, but also has the flexibility of modular replacement, convenient installation and maintenance, and adaptability to different lengths and application requirements, thereby effectively improving the overall safety and reliability of oil pipelines in complex environments.
[0030] In one embodiment, the outer protective component 2 includes a first arc-shaped groove 201 disposed within the semi-circular outer shell 1, with a plurality of mounting brackets 202 disposed inside the first arc-shaped groove 201, and buffer bodies 203 disposed within the mounting brackets 202. The inner protective component 3 includes a second arc-shaped groove 301 disposed within the semi-circular outer shell 1 and located inside the outer protective component 2, with a corrugated elastic plate 302 disposed within the second arc-shaped groove 301. Limiting grooves 303 are provided at both ends of the second arc-shaped groove 301, and limiting blocks 304 are provided at both ends of the corrugated elastic plate 302 within the limiting grooves 303. Thus, the outer layer uses buffer bodies 203 to absorb the initial impact, and the inner layer is configured with corrugated elastic plates 302 to further dissipate residual energy. This multi-layered and gradient anti-collision energy absorption design effectively improves the impact buffering capacity of the entire device, and can better disperse and release stress caused by external impacts, preventing pipeline rupture or damage.
[0031] The outer protective component 2 mainly consists of a buffer body 203, which uses highly elastic or energy-absorbing materials to absorb and disperse the initial forces applied to the pipeline by external impacts and sudden shocks, thus playing a preliminary buffering and shock-absorbing role. The inner protective component 3 mainly consists of a corrugated elastic plate 302. The corrugated elastic plate 302 has good deformation capacity and energy dissipation characteristics. After the outer buffer, it further dissipates the residual impact energy and prevents the transmission of minor or continuous stress to the pipeline body.
[0032] The corrugated elastic plate 302 utilizes the flexible deformation characteristics of its corrugated structure to absorb and dissipate a large amount of mechanical energy through its own bending, compression and rebound when subjected to external impact, thereby effectively reducing the direct effect of stress concentration on the pipeline.
[0033] In one embodiment, the connecting part 4 includes connecting plates 401 disposed on both sides of the semi-circular outer shell 1. Two adjacent connecting plates 401 are connected by fasteners 402, thereby achieving a high-strength, detachable connection between adjacent semi-circular outer shells 1.
[0034] Fastener 402 uses a combination of screws and nuts, which securely connects the two connecting plates 401, thereby creating a high-strength connection between the two semi-circular outer shells 1, which then surround and enclose the pipe. Furthermore, the two ends of the semi-circular outer shells 1 of this invention utilize positioning holes 6 and positioning pins 7 to further enhance the positioning accuracy during assembly, ensuring a tight axial alignment of all components. The positioning pins include both circular and diamond-shaped types.
[0035] In one embodiment, the auxiliary support mechanism 5 includes a U-shaped connecting block 501 disposed at the bottom of the semi-circular outer shell 1, and a connecting plate 401 located inside the U-shaped connecting block 501. A fixing block 502 is disposed at the bottom of the U-shaped connecting block 501, and a ground nail-type support column 503 (i.e., its bottom is a ground nail-shaped structure) is disposed inside the fixing block 502. Bolts 504 are screwed into the side wall of the U-shaped connecting block 501, and the ends of the bolts 504 abut against the side wall of the connecting plate 401 inside the U-shaped connecting block 501, thereby giving the semi-circular outer shell 1 better stability and anti-overturning ability when covering the oil transportation pipeline.
[0036] A U-shaped connecting block 501 is installed at the bottom of the semi-circular outer shell 1. A connecting plate 401 is located within the U-shaped connecting block 501, ensuring a secure connection between the U-shaped connecting block 501 and the semi-circular outer shell 1. A fixing block 502 is provided at the bottom of the U-shaped connecting block 501, containing a ground-pile type support column 503, which firmly anchors the device to the ground (or foundation structure), greatly improving the overall structure's resistance to overturning and displacement. The end of the bolt 504 directly acts on the side wall of the connecting plate 401, effectively preventing component displacement or loosening, ensuring structural stability and safety in actual use. Simultaneously, the bolt 504 can be directly threaded onto the connecting plate 401 according to actual scenarios and requirements, further improving the stability of the connection.
[0037] The 503 ground-mounted support post enhances the stability, overturning resistance, and ease of installation of pipeline protection devices. However, due to ground material, on-site construction conditions, or other special requirements, expansion bolts, chemical anchors, and other support methods can be used as alternatives.
[0038] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0039] First, identify the pipe section requiring protection and clean the surrounding area. Measure and plan the length, quantity, and installation location of the protective devices. Arrange semi-circular shells 1, each with outer and inner buffer layers, symmetrically on both sides of the pipe. Connect two semi-circular shells 1 using the connecting part 4. Several sets of semi-circular shells 1 can be precisely installed on the outside of the pipe using positioning holes 6 and positioning pins 7. Assemble the modules sequentially according to the required length, gradually completing the positioning and connection.
[0040] Install auxiliary support mechanism 5, embed U-shaped connecting block 501, fixing block 502 and ground nail support column 503 into the ground or foundation as needed, and adjust bolt 504 to ensure stability and no loosening.
[0041] When an external impact occurs (such as falling objects, vehicle collisions, geological deformation, etc.), the semi-circular outer shell initially absorbs the force, and the outer protective component 2 (buffer 203) absorbs the main primary impact energy. Subsequently, the residual impact energy is transferred to the inner protective component 3, where the corrugated elastic plate 302 further disperses and dissipates the energy, maximizing the relief of stress on the pipeline body. Upon detection of localized damage, the damaged module can be partially disassembled, repaired, or replaced without the need for complete removal or replacement of the entire device, thus improving maintenance efficiency and reducing costs.
[0042] In summary, this utility model, through the coordinated configuration of the outer protective component 2 and the inner protective component 3, and the combination of the modular connecting part 4 and the stable auxiliary support mechanism 5, not only achieves efficient buffering and collision protection for oil transportation pipelines, but also possesses the flexibility of modular replacement, convenient installation and maintenance, and adaptation to different lengths and application requirements, thereby effectively improving the overall safety and reliability of oil pipelines in complex environments. By using the outer protective component 2 and the inner protective component 3 in conjunction, a multi-layered, gradient collision-absorbing design is achieved, effectively improving the impact buffering capacity of the entire device, better dispersing and releasing stress caused by external impacts, and preventing pipeline rupture or damage. The connecting part 4 enables a high-strength, detachable connection between adjacent semi-circular outer shells 1, and the positioning holes 6 and positioning pins 7 further enhance the positioning accuracy during assembly, ensuring tight axial alignment of all components. The auxiliary support mechanism 5 provides the semi-circular outer shell 1 with better stability and anti-overturning capability when encasing the oil transportation pipeline.
