Description

Technical Field

[0001] This utility model relates to the field of municipal engineering, specifically to an integrated underground pipeline. Background Technology

[0002] Underground pipelines are pipes laid underground to transport liquids, gases, or loose solids. They are an important component of urban infrastructure, undertaking vital functions such as transporting various media, providing energy, and offering communication services. Depending on the media they transport, underground pipelines can be categorized into water supply pipelines, drainage pipelines (including rainwater and sewage pipelines), gas pipelines, heating pipelines, power pipelines, communication pipelines, and industrial pipelines, among others.

[0003] In daily life, underground pipelines are inevitably damaged due to construction projects, traffic accidents, natural disasters, human-caused damage, or design flaws. Since underground pipelines are buried underground, damage may not be detected in time, leading to a waste of public resources and even causing explosions.

[0004] To solve the above problems, it is often necessary to pre-bury sensors along the pipeline, which is not only cumbersome to operate, but also has limited monitoring effect. Summary of the Invention

[0005] In view of the shortcomings of existing technologies, the purpose of this utility model is to provide an integrated underground pipeline that can promptly detect the location of damage, reduce the waste of public resources, and lower the probability of danger.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a main pipe and an optical fiber duct. The optical fiber duct is composed of multiple pipe units connected end to end in a longitudinal direction. Multiple mounting seats are arranged on the upper part of the main pipe in a longitudinal direction. Each mounting seat is located at the connection point of an adjacent pipe unit and fixes and connects the adjacent pipe units. When the main pipe is damaged, the pipe unit is damaged along with the main pipe.

[0007] By adopting the above technical solution, compared with the traditional method of additional pre-embedded sensors, the fiber optic pipe for monitoring damage to the main pipe is integrated above the main pipe, forming an integrated underground pipe. The structure is more streamlined and the installation difficulty is reduced. When the main pipe is damaged, the fiber optic pipe will also be damaged, causing the fiber inside the fiber optic pipe to break. The circuit connected to the fiber will detect the corresponding fiber signal interruption, which can quickly determine the damage to the main pipe and accurately determine the location of the damage. This allows for rapid notification of maintenance personnel to go to the site for repair, thereby reducing the waste of public resources and lowering the probability of danger. Secondly, the fiber optic pipe, composed of multiple pipe units connected end to end, can be assembled with different numbers of pipe units according to different main pipe lengths, without the need for customized production based on prior knowledge of the specific dimensions, effectively improving production efficiency. At the same time, the standard unit size also greatly reduces transportation difficulty. Finally, the mounting base serves not only as a connecting structure for the pipe units but also as a point of force application for damage. After the main pipe is damaged, the misaligned mounting base will stably cause significant damage to the fiber optic pipe, ensuring normal operation.

[0008] The present invention is further configured such that: the mounting base includes a seat body and a pressure cap that are detachably and fixedly fitted together; the seat body is integrally disposed on the main body; the pressure cap is located above the seat body; the mounting base and the pressure cap are respectively provided with semi-circular mounting notches along the longitudinal direction; the mounting notches of the mounting base and the pressure cap are combined to form a mounting hole for inserting a pipe unit into the mounting base; the seat body and the pressure cap are respectively provided with semi-circular arc-shaped limiting recesses at the longitudinal center of the mounting hole; the limiting recesses of the mounting base and the pressure cap are combined to form a limiting groove; and each of the pipe units is respectively provided with a limiting ring located in the limiting groove on the outer periphery of its longitudinal end.

[0009] By adopting the above technical solution, the detachable and fixed mounting body and gland allow for quick disassembly or replacement of any pipe unit during maintenance, improving maintenance efficiency. At the same time, the mounting hole and limiting groove ensure the installation reliability of the pipe unit and prevent it from coming off the mounting base.

[0010] The present invention is further configured such that each of the aforementioned limiting recesses is provided with an arc-shaped sealing sheet along the circumferential direction, which seals and cooperates with the outer circumference of the limiting ring.

[0011] By adopting the above technical solution and adding an arc-shaped sealing sheet, on the one hand, impurities are prevented from entering the pipeline unit and affecting the normal operation of the optical fiber; on the other hand, the gap between the inner wall of the limiting recess and the outer circumference of the limiting ring is accurately filled, making the installation of the limiting ring more stable.

[0012] The present invention is further configured such that: the longitudinal ends of the limiting recess are respectively provided with arc-shaped guide grooves that are inserted into the ends of the arc-shaped sealing sheet, and the arc-shaped guide grooves extend circumferentially to the ends of the mounting base and the pressure cover to form an installation port for installing the arc-shaped sealing sheet.

[0013] By adopting the above technical solution, the arc-shaped guide groove not only makes the arc-shaped sealing sheet stably confined to the inner side wall of the limiting recess, but also makes the installation of the arc-shaped sealing sheet easier.

[0014] The present invention is further configured such that the longitudinal length of the limiting groove is greater than the sum of the widths of the two limiting rings.

[0015] By adopting the above technical solution, a margin is reserved in the limiting groove to accommodate the two limiting rings. On the one hand, this makes the installation of the pipeline unit simpler, and on the other hand, it reduces the impact on the pipeline unit when the main pipe undergoes thermal expansion and contraction.

[0016] The present invention is further configured such that: a fixing block is provided on each of the transverse sides of the base and the pressure cover; a screw rod passing through the fixing block of the pressure cover is fixedly provided above the fixing block of the base; a threaded nut is provided above the fixing block of the pressure cover on the screw rod; and a compression spring is sleeved on the screw rod and compressed between the nut and the fixing block.

[0017] By adopting the above technical solution, the nut and screw work together to form a fixed fit between two fixing blocks, which in turn forms a fixed fit between the seat and the cover. This makes it easier to assemble and disassemble the seat and the cover. At the same time, since there is frequent vibration on the road, the compression spring set between the nut and the fixing block can effectively reduce the impact of vibration on the nut and ensure the reliability of the fixation.

[0025] like Figure 1 — Figure 5 As shown, this utility model discloses an integrated underground pipeline, including a main pipe 1 and an optical fiber duct 2. The optical fiber duct 2 is composed of multiple pipe units 21 connected longitudinally end to end. Multiple mounting seats 11 are arranged longitudinally above the main pipe 1, each mounting seat 11 located at the connection point of adjacent pipe units 21 and fixing and connecting them. When the main pipe 1 is damaged, the pipe unit 21 is damaged along with the main pipe 1. Compared to traditional methods with additional pre-embedded sensors, integrating the optical fiber duct 2, which monitors damage to the main pipe 1, above the main pipe 1 forms an integrated underground pipeline. This results in a more streamlined structure and reduced installation difficulty. When the main pipe 1 is damaged, the optical fiber duct 2 will also be damaged, causing the optical fiber inside the optical fiber duct 2 to break. The circuit connecting the optical fiber will then detect... Upon detecting a corresponding fiber optic signal interruption, the damage to the main pipeline can be quickly identified and its location accurately determined. This allows for rapid notification of maintenance personnel to the site for repairs, reducing waste of public resources and lowering the probability of accidents. Secondly, the fiber optic pipeline 2, composed of multiple pipeline units 21 connected end-to-end, can be assembled with different numbers of pipeline units 21 depending on the length of the main pipeline. This eliminates the need for pre-determined dimensions and customized production, effectively improving production efficiency. Furthermore, the standardized unit size significantly reduces transportation difficulties. Finally, the mounting base 11 serves not only as a connecting structure for the pipeline units 21 but also as a point of force application for damage. After the main pipeline 1 is damaged, the misaligned mounting base 11 stably inflicts significant damage on the fiber optic pipeline 2, ensuring normal operation.

[0026] The mounting base 11 includes a base body 111 and a pressure cap 112 that are detachably and fixedly fitted together. The base body 111 is integrally formed on the main pipe body 1, and the pressure cap 112 is located above the base body 111. Semi-circular mounting notches 113 are respectively provided longitudinally above the mounting base 11 and below the pressure cap 112. The mounting notches 113 of the mounting base 11 and the pressure cap 112 combine to form a mounting hole for the pipe unit 21 to be inserted into the mounting base 11. The base body 111 and the pressure cap 112 are respectively provided at the longitudinal center of the mounting hole. The semi-circular limiting recess 114, the limiting recess 114 of the mounting base 11 and the pressure cap 112 are combined to form a limiting groove. Each pipe unit 21 is provided with a limiting ring 211 located in the limiting groove on the outer periphery of its longitudinal end. The detachable and fixedly fitted base 111 and pressure cap 112 can be quickly disassembled or replaced during maintenance, improving maintenance efficiency. At the same time, the mounting hole and the limiting groove ensure the installation reliability of the pipe unit 21 and prevent it from coming off the mounting base 11.

[0027] Each limiting recess 114 is provided with an arc-shaped sealing piece 115 along the circumferential direction to seal with the outer circumference of the limiting ring 211. The addition of the arc-shaped sealing piece 115 serves two purposes: firstly, it prevents impurities from entering the pipe unit 21 and affecting the normal operation of the optical fiber; secondly, it accurately fills the gap between the inner wall of the limiting recess 114 and the outer circumference of the limiting ring 211, making the installation of the limiting ring 211 more stable.

[0028] The longitudinal ends of the limiting recess 114 are respectively provided with arc-shaped guide grooves 116 that are inserted into the ends of the arc-shaped sealing piece 115. The arc-shaped guide grooves 116 extend circumferentially to the ends of the mounting base 11 and the pressure cap 112 and form an installation port 117 for installing the arc-shaped sealing piece 115. The arc-shaped guide grooves 116 not only make the arc-shaped sealing piece 115 stably limited in the inner wall of the limiting recess 114, but also make the installation of the arc-shaped sealing piece 115 easier.

[0029] The longitudinal length a of the limiting groove is greater than the sum of the width b of the two limiting rings 211. The limiting groove is reserved to accommodate the two limiting rings 211. On the one hand, this makes the installation of the pipe unit 21 simpler. On the other hand, it reduces the impact on the pipe unit 21 when the main pipe 1 undergoes thermal expansion and contraction.

[0030] Fixing blocks 118 are respectively provided on the lateral sides of the base 111 and the pressure cover 112. A screw 119 is fixedly installed above the fixing block 118 of the base 111, passing through the fixing block 118 of the pressure cover 112. A threaded nut 110 is provided above the fixing block 118 of the pressure cover 112 on the screw 119. A compression spring 1101 is sleeved on the screw 119 and compressed between the nut 110 and the fixing block 118. The nut 110 and the screw 119 cooperate to form a fixed fit between the two fixing blocks 118, which constitutes a fixed fit between the base 111 and the pressure cover 112, making it easier to assemble and disassemble the base 111 and the pressure cover 112. At the same time, since there is frequent vibration on the road, the compression spring 1101 between the nut 110 and the fixing block 118 can effectively reduce the impact of vibration on the nut 110 and ensure the reliability of the fixation.
