Abstract
Description
Technical Field
[0001] This utility model relates to the field of long-distance pipeline and optical fiber fixing technology, specifically a long-distance gas pipeline and optical fiber fixing structure. Background Technology
[0002] Current gas transportation methods mainly rely on pipelines. Gas pipelines generally have long transmission distances, and the environments along the pipelines vary. Pipelines are often damaged by external forces or natural erosion, increasing operational risks and maintenance costs. With technological advancements, many manufacturers use optical fibers laid around the pipelines to monitor their health. However, due to the long length of gas pipelines, a significant portion of them are located in areas with heavy rainfall or cross ditches and rivers. Rainwater and river water wash away sediment, and because gas pipelines are relatively lightweight, both the pipelines and optical fibers are prone to displacement, posing significant challenges to pipeline health monitoring.
[0003] In existing technologies, although it is possible to fix pipes and optical fibers, they are often welded to brackets. This not only increases construction costs and prolongs installation time, causing unnecessary waste, but also inevitably leads to problems such as increased construction costs, unreliable installation, potential operational hazards, and difficulties in later maintenance. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a long-distance gas pipeline and optical fiber fixing structure, which can effectively solve the problems in the prior art, which usually welds the fiber to the bracket, which not only increases the construction cost and prolongs the installation time, causing unnecessary waste, but also inevitably increases the construction cost, makes the installation unreliable, poses hidden dangers in operation, and makes later maintenance difficult.
[0005] The technical solution adopted by this utility model is: a long-distance gas pipeline, including a fixed seat, an extension seat and a pipeline body. A cavity is opened at the inner edge of the fixed seat. The cross-section of the fixed seat is a "triangular" structure. The fixed seat and the extension seat are an integral structure. Slots and positioning holes are opened at both ends of the extension seat away from the fixed seat. Ribs are inserted and installed at the inner edge of the slots. The pipeline body is placed in the cavity of the fixed seat.
[0006] Preferably, the fixing seat is a cement concrete structure with a thickness of 30mm to 60mm.
[0007] The above technical solution uses cement concrete to fix the pipe, and the thickness of 30mm to 60mm gives it both high strength and lightweight characteristics. The rigid structure of the concrete can resist soil lateral pressure and ground load, preventing the pipe body from shifting or deforming.
[0008] Preferably, the extension seat is made of cement concrete, the thickness of the extension seat is in the range of 40mm to 80mm, and the extension length of the extension seat is in the range of 200mm to 300mm.
[0009] Through the above technical solution, the 40mm-80mm thickness and 200mm-300mm extension length of the extension seat can increase the supporting base area of the fixed seat, reduce the soil pressure per unit area, and avoid the pipe body bending due to soil settlement.
[0010] Preferably, a reserved groove is provided at the inner edge of the fixing seat, and a protective plate is fixedly installed on the fixing seat through the reserved groove. The fixing seat is in contact with the outer wall of the pipe body through the protective plate.
[0011] The above technical solution uses a protective plate that fits against the outer wall of the pipe body through a pre-reserved groove. This buffers the vibration of the pipe during operation and prevents the concrete of the fixing seat from directly rubbing against the anti-corrosion layer of the pipe body. This ensures the fixing effect and prevents damage to the pipe body caused by rigid compression.
[0012] Preferably, both the slot and the rib have an "I" shaped cross-section, and the end of the rib away from the fixing seat is threaded with a positioning bolt and extends into the positioning hole.
[0013] Through the above technical solution, the slot and rib of the I-shaped cross section can withstand a large shear force. The positioning bolt passes through the positioning hole to lock the rib, realizing a rigid connection between adjacent fixed seats. When a section of the pipe is subjected to external force, the load can be transferred to the adjacent fixed seat through the rib, avoiding single-point force damage.
[0014] Preferably, the slots, positioning holes, ribs, and positioning bolts are provided in two identical sets, and each set has two identical slots, positioning holes, ribs, and positioning bolts, which are symmetrically distributed about the center line of the fixing seat.
[0015] Through the above technical solution, the two sets of symmetrically distributed ribs can balance the soil thrust on both sides of the pipeline and prevent the fixed seat from tilting due to eccentric load. In the pipeline bend section, the symmetrical structure can offset the lateral thrust and ensure that the pipeline axis deviation does not exceed the design value. It is especially suitable for the transition area between the straight section and the bend section of the high-pressure gas pipeline.
[0016] This utility model also provides an optical fiber fixing structure, wherein the fixing seat holds the optical fiber body through a cavity, and a through hole is opened at the end of the fixing seat away from the optical fiber body. The optical fiber body is fixed to the top of the cavity using a strip. The fixing seat and the extension seat are provided in multiple identical sets and are distributed at equal intervals.
[0017] The above technical solution involves fixing the optical fiber body to the top of the cavity via a strip, with through holes for threading the optical fiber, which facilitates monitoring the health of the pipeline.
[0018] Compared with the prior art, this utility model provides a long-distance gas pipeline and optical fiber fixing structure, which has the following beneficial effects:
[0019] 1. The long-distance gas pipeline and optical fiber fixing structure uses a triangular fixing device as the main body. The structure is simple and increases the overall stability. The cement concrete material is low cost and easy to install, making it suitable for the use of long-distance gas pipelines. The interval fixing of the long-distance gas pipeline and optical fiber fixing structure provides convenience for the later maintenance of pipelines and optical fibers.
[0020] 2. In the water-crossing section of the long-distance gas pipeline and the optical fiber fixing structure, the relative position of the pipeline and the optical fiber is not affected by the buoyancy of the water or the flow of silt. The optical fiber body is fixed to the top of the cavity by a strip, and the through hole is used for optical fiber threading, which facilitates the monitoring of the pipeline's health.

[0030] 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.
[0031] Example 1: As Figure 1-8 As shown, the present invention provides a long-distance gas pipeline, including a fixed seat 1, an extension seat 8 and a pipeline body 11. A cavity 2 is provided at the inner edge of the fixed seat 1. The fixed seat 1 has a triangular cross-section. The fixed seat 1 and the extension seat 8 are integral structures. Slots 6 and positioning holes 7 are provided at both ends of the extension seat 8 away from the fixed seat 1. Ribs 9 are inserted and installed at the inner edge of the slots 6. The pipeline body 11 is placed in the cavity 2 of the fixed seat 1.
[0032] Specifically, the fixing seat 1 is a cement concrete structure with a thickness of 30mm to 60mm. The advantage is that by using cement concrete to fix the seat 1, and with a thickness of 30mm to 60mm, it has both high strength and lightweight characteristics. The rigid structure of the concrete can resist soil lateral pressure and ground load, preventing the pipe body 11 from shifting or deforming.
[0033] Specifically, the extension seat 8 is made of cement concrete. The thickness of the extension seat 8 ranges from 40mm to 80mm, and the extension length of the extension seat 8 is from 200mm to 300mm. The advantage is that the thickness of the extension seat 8 (40mm to 80mm) and the extension length (200mm to 300mm) can increase the support base area of the fixed seat 1, reduce the soil pressure per unit area, and avoid the pipe body 11 bending due to soil settlement.
[0034] Specifically, a reserved groove 4 is provided at the inner edge of the fixing seat 1. The fixing seat 1 is fixedly installed with a protective plate 5 through the reserved groove 4. The fixing seat 1 is attached to the outer wall of the pipe body 11 through the protective plate 5. The advantage is that by attaching the protective plate 5 to the outer wall of the pipe body 11 through the reserved groove 4, the vibration of the pipe during operation can be buffered, and the concrete of the fixing seat 1 can be prevented from directly rubbing against the anti-corrosion layer of the pipe body 11. This ensures the fixing effect and prevents the pipe body 11 from being damaged by rigid compression.
[0035] Specifically, both the slot 6 and the rib 9 have an "I" shaped cross-section. The end of the rib 9 furthest from the fixed seat 1 is threaded with a positioning bolt 10 and extends into the positioning hole 7. The advantage is that the slot 6 and the rib 9 with the I-shaped cross-section can withstand a large shear force. The positioning bolt 10 passes through the positioning hole 7 to lock the rib 9, realizing a rigid connection between adjacent fixed seats 1. When a section of the pipe is subjected to external force, the load can be transferred to the adjacent fixed seat 1 through the rib 9, avoiding single-point force damage.
[0036] Specifically, slots 6, positioning holes 7, ribs 9, and positioning bolts 10 are all provided in two identical sets. Each set of slots 6, positioning holes 7, ribs 9, and positioning bolts 10 has two identical sets and is symmetrically distributed about the center line of the fixing seat 1. The advantage is that the two sets of symmetrically distributed ribs 9 can balance the soil thrust on both sides of the pipeline and prevent the fixing seat 1 from tilting due to eccentric load. In the pipeline bend section, the symmetrical structure can offset the lateral thrust and ensure that the pipeline axis deviation does not exceed the design value. It is especially suitable for the transition area between the straight section and the bend section of the high-pressure gas pipeline.
[0037] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.
[0038] This utility model also provides an optical fiber fixing structure. The fixing seat 1 holds the optical fiber body 12 through the cavity 2. The fixing seat 1 has a through hole 3 at the end away from the optical fiber body 12. The optical fiber body 12 is fixed to the top of the cavity 2 by a strip. The fixing seat 1 and the extension seat 8 are provided with multiple identical sets and are distributed at equal intervals.
[0039] The advantage is that the optical fiber body 12 is fixed to the top of the cavity 2 by the strip, and the through hole 3 is used for optical fiber threading, which facilitates the monitoring of the health of the pipeline.
[0040] Working Principle: During use, the fixing seat 1 is made of cement concrete with a thickness of 30mm to 60mm, giving it both high strength and lightweight characteristics. The rigid structure of the concrete can resist soil lateral pressure and ground load, preventing displacement or deformation of the pipe body 11. The extension seat 8, with a thickness of 40mm to 80mm and an extension length of 200mm to 300mm, can increase the support base area of the fixing seat 1, reduce the soil pressure per unit area, and prevent the pipe body 11 from bending due to soil settlement. The protective plate 5 fits against the outer wall of the pipe body 11 through the reserved groove 4, which can buffer the vibration of the pipe during operation and prevent the concrete of the fixing seat 1 from directly rubbing against the anti-corrosion layer of the pipe body 11. This ensures both the fixing effect and prevents rigid compression. Damage to the pipe body 11 is caused by the I-shaped slot 6 and the rib 9, which can withstand large shear forces. The positioning bolt 10 passes through the positioning hole 7 to lock the rib 9, realizing a rigid connection between adjacent fixed seats 1. When a section of the pipe is subjected to external force, the load can be transferred to the adjacent fixed seat 1 through the rib 9, avoiding single-point force damage. The two sets of symmetrically distributed ribs 9 can balance the soil thrust on both sides of the pipe and prevent the fixed seat 1 from tilting due to eccentric load. In the pipe bend section, the symmetrical structure can offset the lateral thrust and ensure that the pipe axis deviation does not exceed the design value. It is especially suitable for the transition area between the straight section and the bend section of the high-pressure gas pipeline. The optical fiber body 12 is fixed to the top of the cavity 2 by the strip. The through hole 3 is used for optical fiber threading, which can facilitate the monitoring of the health of the pipeline.
