Description

A pipeline with built-in leak detection and alarm function Technical Field

[0001] This invention belongs to the field of pressure pipeline leak detection and alarm technology, specifically a pipeline with built-in leak detection and alarm function. Background Technology

[0002] In municipal construction and industrial production, pressure pipelines (such as PE gas pipes and PE water supply pipes) are critical infrastructure for fluid transportation, and their safe and stable operation is directly related to residents' lives, industrial production, and public safety. However, these pressure pipelines are prone to bursting or leakage during long-term use due to various factors. Specifically, pipelines may be damaged by external factors such as construction damage or third-party sabotage; or their strength may decrease due to media corrosion or aging, resulting in leakage.

[0003] Pipeline bursts or leaks often go undetected. This not only leads to leaks of gases and other media, wasting resources, but can also cause serious safety accidents, posing a significant threat to the surrounding environment and the safety of people and property. Moreover, locating the underground leak becomes a major challenge once the problem occurs. Currently, investigations rely heavily on manpower and resources. Workers need to traverse the pipeline route step by step, using simple tools and experience to determine the leak's location. This process is time-consuming and labor-intensive, often requiring a significant investment of time to pinpoint the exact location of the leak. Summary of the Invention

[0004] This invention overcomes the shortcomings of existing technologies and proposes a pipeline with built-in leak detection and alarm functions; this invention is achieved through the following technical solution:

[0005] A pipeline with built-in leak detection and alarm function includes a pipeline body, a composite strip, arc-shaped clamps, a reinforcement component, and a controller. The pipeline body is segmented, with an installation plate along its length on one side. A composite strip is wrapped around the outer wall of the pipeline body to detect stress changes on the outer wall. Multiple sets of arc-shaped clamps are equidistantly arranged on the outer wall of the pipeline body. Each set includes two arc-shaped clamps symmetrically arranged on both sides of the pipeline body. A reinforcement component is installed between the installation plate and the arc-shaped clamps.

The outer wall of the bidirectional screw is symmetrically threaded with threaded blocks. The side wall of the threaded block is fixedly connected to the corresponding arc-shaped clamping plate. The side wall of the slide A is symmetrically fixedly connected to the guide rod. The arc-shaped clamping plate has symmetrically opened limit holes at the end near the threaded block. The guide rod is placed inside the corresponding limit hole and is slidably connected to the inner wall of the limit hole.

[0009] Furthermore, a rack A is fixedly connected to the side wall of the mounting plate near the top, and a motor AA is fixedly connected to the top of each slide A. A gear A is fixedly connected to the output end of each motor AA, and the gears A mesh with the rack A.

[0010] Furthermore, each slide A is fixedly connected to a warning light. When the composite belt detects abnormal stress in the pipe body, the controller activates the reinforcement components, and the warning light illuminates simultaneously.

[0015] The beneficial effects of this invention compared to the prior art are as follows:

[0016] 1. This invention utilizes a superconducting optical fiber embedded in a composite strip to achieve real-time monitoring of stress changes. It can trigger a reinforcement mechanism when minor damage occurs in the pipeline, using an arc-shaped clamp to protect against further leakage. Furthermore, it can immediately initiate flow diversion and interception in the event of a pipe burst, preventing large-scale media leakage. This reduces the probability of secondary disasters and provides dual protection for personnel, property, and the surrounding environment.

[0017] 2. When the stress change detected by the composite belt reaches the preset threshold range, the arc-shaped clamps are controlled to move closer to each other, so that the rubber pads on their inner walls completely adhere to the protective layer on the outer wall of the pipeline body. The rubber pads cover the stress abnormal area through elastic deformation, forming physical reinforcement, which effectively prevents the expansion of minor leaks, avoids more serious problems caused by leaks, and ensures the normal operation of the pipeline.

[0018] 3. While the curved clamp is being physically reinforced, the warning light at the bottom of slide A illuminates, issuing a localized anomaly warning signal. This signal allows ground inspection personnel to quickly locate areas with minor hazards and take timely further inspection and handling measures, improving the efficiency of hazard identification and resolution.

[0019] 4. When the stress change detected by the composite belt exceeds the preset threshold, valve body one at both ends of the burst pipe section is activated to cut off the input medium and block the output. Simultaneously, the internal channel of valve body one is switched to connect with valve body two, preparing for medium diversion. This rapid sealing mechanism effectively prevents large-scale medium leakage, reducing resource waste and environmental damage.

[0020] 5. Simultaneously with the emergency diversion of the burst pipe, the marking component activates, and a fluorescent pen leaves a bar mark on the marking board corresponding to the burst pipe location, visualizing the leak's location. This visual marking method allows maintenance personnel to quickly and accurately locate the leak, eliminating the need for lengthy investigations and significantly improving maintenance efficiency. At the same time, the alarm light in the center of the mounting bracket illuminates, emitting a strong visual alarm. This alarm signal, in conjunction with the visual markings on the marking board, provides maintenance personnel with multi-dimensional guidance, enabling them to quickly locate potential hazard areas in complex field environments, further shortening maintenance time.

The technical solutions of this invention are described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

The pipeline with built-in leak detection and alarm function includes: pipeline body 1, composite belt 3, arc-shaped clamp 4, reinforcement component, marking plate 5 and marking component. The pipeline body 1 is a segmented design, and an installation plate 2 is provided on one side of the pipeline body 1 along the length direction. The composite belt 3 is wrapped around the outer wall of the pipeline body 1. The composite belt 3 is used to detect stress changes on the outer wall of the pipeline body 1, and a protective layer 301 is provided on the outer wall of the composite belt 3. Multiple sets of arc-shaped clamps 4 are equidistantly arranged on the outer wall of the pipe body 1. Each set includes two arc-shaped clamps 4 symmetrically arranged on both sides of the pipe body 1. Rubber pads 401 are installed on the inner side walls of the arc-shaped clamps 4. A reinforcement component is installed between the mounting plate 2 and the arc-shaped clamps 4. The reinforcement component drives the two arc-shaped clamps 4 in each set to move relative to each other, which is used to clamp and reinforce the area on the outer wall of the pipe body 1 where stress changes occur. A marking plate 5 is provided on the upper part of the pipe body 1 along the length direction. A marking component is installed between the mounting plate 2 and the marking plate 5. The marking component is used to mark the leaking area of ​​the pipe body 1 at the position corresponding to the marking plate 5.

[0035] The specific technology of the composite strip 3 is as follows: the superconducting optical fiber is pre-coated to form a flexible composite strip 3, and then this composite strip 3 is spirally wound around the outside of the pipe body 1, and then combined together by co-extrusion technology. Finally, a protective layer 301 is covered on the outside to form an integral shape.

[0036] Each pair of adjacent pipe bodies 1 are connected at their closest ends by a valve body 6. A ball valve 7 is rotatably connected inside each valve body 6. Multiple mounting seats 8 are fixedly connected to the side wall of the mounting plate 2, and the mounting seats 8 are located at the connection point of two adjacent pipe bodies 1. A motor 9 is fixedly connected inside each mounting seat 8. The output end of the motor 9 passes through the inner wall of the corresponding valve body 6 and is fixedly connected to the corresponding ball valve 7. The ball valve 7 is a three-way ball valve, and a sealing element is installed inside each valve body 6.

[0037] Please refer to Figures 2 to 8, 10, and 11. Each valve body 6 has a valve body 20 installed at its bottom. Each valve body 20 has a ball valve 21 rotatably connected inside. Each mounting base 8 has a motor 2101 fixedly connected to its inner wall. The output end of each motor 2101 passes through the inner wall of the corresponding valve body 20 and is fixedly connected to the corresponding ball valve 21. The ball valve 21 is a three-way ball valve, and each valve body 20 has a sealing element installed inside.

[0038] A support frame 22 is fixedly connected to the inner wall of the valve body 20 near its input end. A flow sensor 2301 is fixedly installed on one side of the support frame 22, and an arc plate 23 is symmetrically rotatably connected to the other side. A tension spring 24 is symmetrically fixedly connected to the side of the support frame 22 near the flow sensor 2301. The other end of the tension spring 24 is fixedly connected to the corresponding arc plate 23. A sealing gasket 25 is installed on the side of the support frame 22 near the arc plate 23. The arc plate 23 contacts the corresponding sealing gasket 25. An alarm light 26 is fixedly connected to the middle of the mounting base 8.

[0039] Each mounting base 8 has a controller installed inside; the controller is used to control the activation of ball valve 7 and ball valve 21, as well as the activation of the reinforcement and marking components.

[0040] A spare pipe 35 is installed between each of the two adjacent valve bodies 20, and both ends of the spare pipe 35 are connected to the corresponding valve body 20.

[0041] When adjacent pipe sections 1 experience consecutive bursts, motor 9 on the side of valve body 6 at the input end of the newly burst pipe section 1 starts, causing ball valve 7 to rotate 90 degrees counterclockwise, changing its shape from "L" to "X". Simultaneously, motor 2101 on the side of valve body 20 at the output end of the newly burst pipe section 1 starts, causing ball valve 21 to rotate 90 degrees counterclockwise, changing its shape from "L" to "X". Then, the medium flows from the pipe section where the new burst pipe section is located... The medium flows downward through the valve body 6 installed at the input end of the main body 1, and flows into the backup pipe body 35 through the ball valve 21 at the bottom. After the medium enters the backup pipe body 35, it continues to flow. When it comes into contact with the flow sensor 2301 inside the valve body 20 at the bottom of the newly burst pipe section, the corresponding controller controls the motor 2101 on one side of the valve body 20 to start again, and drives the ball valve 21 to rotate 90 degrees counterclockwise again, changing from a "┥" shape to a "T" shape. The channel of the backup pipe body 35 switches to the horizontal connection state and continues to flow.

[0042] The reinforcement components include: a motor A10, a bidirectional screw 11, a threaded block 12, and a guide rod 13. A slide rail 14 is fixedly connected to the side wall of the mounting plate 2. A slide block A15 corresponding to the arc-shaped clamping plate 4 is slidably connected to the outer wall of the slide rail 14. A motor A10 is fixedly connected to the bottom of each slide block A15. A bidirectional screw 11 is fixedly connected to the output end of each motor A10. Threaded blocks 12 are symmetrically threaded to the outer wall of each bidirectional screw 11. The side wall of the threaded block 12 is fixedly connected to the corresponding arc-shaped clamping plate 4. Guide rods 13 are symmetrically fixedly connected to the side wall of each slide block A15. Limiting holes are symmetrically opened inside the arc-shaped clamping plate 4 near the threaded block 12. Guide rods 13 are placed inside the corresponding limiting holes and are slidably connected to the inner wall of the limiting holes.

[0043] A rack A16 is fixedly connected to the side wall of the mounting plate 2 near the top. A motor AA17 is fixedly connected to the top of the slide A15. A gear A18 is fixedly connected to the output end of the motor AA17. The gears A18 mesh with the rack A16.

[0044] Warning lights 19 are fixedly connected to the bottom of each slide A15. When the composite belt 3 detects abnormal stress in the pipe body 1, the controller controls the reinforcement components to start, and the warning lights 19 light up simultaneously.

[0045] The marking assembly includes a slide block B27, an electric push rod 28, and a highlighter 29. A groove 30 is provided on the side of the mounting plate 2 away from the pipe body 1. The slide block B27 is equidistantly slidably connected inside the groove 30. A connecting rod 31 is fixedly connected to the top of the slide block B27. An electric push rod 28 parallel to the marking plate 5 is fixedly connected to the other end of the connecting rod 31. A highlighter 29 perpendicular to the marking plate 5 is fixedly connected to the output end of the electric push rod 28.

[0046] Motors B32 are fixedly connected inside the slide block B27, and gears B33 are fixedly connected to the output end of each motor B32. A rack B34 is fixedly connected to the top of the mounting plate 2, and several of the gears B33 mesh with the rack B34.

[0047] The working principle of the pipeline with built-in leak detection and alarm function provided by this invention is as follows:

[0048] In the initial state of normal pipeline operation, all components are in preset standby positions to ensure stable medium delivery and real-time monitoring capabilities. The reinforcement and marking components are both in standby mode, the arc-shaped clamp 4 is in an open state away from the pipeline body 1, and the fluorescent pen 29 remains separate from the marking plate 5. The composite strip 3 wrapped around the outer wall of the pipeline body 1 is continuously in operation, monitoring stress changes on the outer wall of the pipeline body 1 in real time and synchronously transmitting the data to the controller and ground workstation. The protective layer 301 on the outer wall of the composite strip 3 also serves as corrosion protection. It provides protection against corrosion and mechanical damage; all ball valves 7 inside valve body 6 are in an "L"-shaped open state, fully connecting the two adjacent sections of pipeline body 1, ensuring the smooth flow of the main medium transport channel; all ball valves 21 inside valve body 20 are also in an "L"-shaped open state, connecting the adjacent spare pipe body 35, which is in a standby state; under the tension of the tension spring 24, the arc plate 23 inside valve body 20 tightly fits the sealing gasket 25 on one side of the support frame 22, achieving the initial sealing of the input end of valve body 20.

[0049] When the pipe body 1 experiences minor damage or abnormal stress, but does not reach the burst threshold, the superconducting optical fiber embedded in the composite belt 3 detects the stress change on the outer wall of the pipe body 1. When the value reaches the preset threshold range, it immediately sends a trigger signal to the controller and simultaneously uploads the specific location and value of the stress change to the ground workstation, recording the monitoring data synchronously. At the same time, the controller starts the motor AA17 at the top of the slide A15, and the output of the motor AA17 drives the gear A18 to rotate. Since the gear A18 meshes with the rack A16 fixed to the side wall of the mounting plate 2, the slide A15 moves precisely along the slide rail 14 towards the stress change point. During the movement of the slide A15, the controller dynamically calibrates the position through the real-time stress signal fed back by the composite belt 3. When it reaches the position corresponding to the target area, the motor AA17 stops running, and the slide A15 stops at that position.

[0050] The motor A10, fixed at the bottom of the slide A15, starts, and its output drives the bidirectional screw 11 to rotate. The threaded blocks 12, which are symmetrically threaded on the outer wall of the bidirectional screw 11, move closer to each other under the driving force of the threads. The threaded blocks 12 drive the arc-shaped clamp 4, which is fixedly connected to its side wall, to move axially along the guide rod 13. The guide rod 13 passes through the limiting hole of the arc-shaped clamp 4 to ensure a smooth movement trajectory, so that the arc-shaped clamp 4 gradually moves closer to the pipe body 1. Driven by the motor A10, the threaded blocks 12 continue to move until the rubber pad 401 on the inner side wall of the arc-shaped clamp 4 completely fits the protective layer 301 on the outer wall of the pipe body 1. The rubber pad 401 covers the stress abnormal area through elastic deformation, forming physical reinforcement and preventing the expansion of minor leaks. At the same time, the warning light 19 at the bottom of the slide A15 lights up, emitting a local abnormality warning signal, which makes it easy for ground inspection personnel to quickly locate the minor hidden danger area.

[0051] When a pipe bursts in pipeline body 1, and the stress change detected by composite belt 3 exceeds a preset threshold, the system initiates a sealing and marking operation. Specifically: Valve body 6, installed at the input end of pipeline body 1 where the burst pipe section is located, activates motor 9 on one side, causing its output end to rotate ball valve 7 counterclockwise by 90°, changing ball valve 7 from a "T" shape to a "┥" shape. At this time, the medium at the input end is cut off, and the internal channel of valve body 6 switches to the bottom, allowing the medium to flow through the bottom of valve body 6 to valve body 20 below. Simultaneously, motor 9 on one side of valve body 6 at the output end of pipeline body 1 where the burst pipe section is located is activated, causing its output end to rotate ball valve 7 clockwise by 90°, changing ball valve 7 from a "T" shape to a "┝" shape. This action seals the output end of the burst pipe section and connects valve body 20 at the bottom of valve body 6 to the downstream normal pipeline body 1.

[0052] Since the ball valve two 21 inside the valve body two 20 is initially in the "丄" shaped open state, the medium flowing in from the valve body one 6 at the input end of the pipeline body 1 where the pipe burst section is located passes through the internal channel of the valve body two 20 and flows towards the spare pipe body 35 connected to the bottom of the valve body two 20. During this process, since an arc-shaped plate 23 is symmetrically and rotationally connected to the inside of the bottom input end of the valve body two 20, and the arc-shaped plate 23 is in contact with the gasket 25 on one side of the support frame 22, the medium can only flow into the inside of the spare pipe body 35 installed at the bottom output end of the valve body two 20. When the medium flows in the spare pipe body 35 to the valve body two 20 corresponding to the output end of the pipe burst section, it contacts the flow sensor 2301 on the support frame 22 inside the valve body two 20. After the flow sensor 2301 detects the medium flow signal, it sends an instruction to the controller to start the motor two 2101 corresponding to the valve body two 20. The output end of the motor two 2101 drives the corresponding ball valve two 21 to rotate counterclockwise by 90°, so that the ball valve two 21 changes from the "丄" shape to the "┥" shape, and the internal channel of the valve body two 20 switches to the upward connection state. The medium continues to flow, pushes the arc-shaped plate 23 symmetrically and rotationally connected to one side of the support frame 22 to rotate through its pressure, and at the same time the tension spring 24 is stretched. The medium flows upward through this channel and passes through the ball valve two 21 and enters the valve body one 6 installed at the output end of the pipe burst section. At this time, the ball valve one 7 inside the valve body one 6 is in the "┝" shape, and finally flows into the downstream normal pipeline body 1 to ensure the continuity of the medium transportation.

[0053] If the pipeline body 1 adjacent to the output end of the pipe burst section also bursts, the system starts secondary diversion. Specifically, the motor one 9 on one side of the valve body one 6 at the output end of the newly added pipe burst section is started, which drives the ball valve one 7 inside the valve body one 6 to rotate clockwise by 90° to be in the "┝" shape for blocking. At the same time, the motor two 2101 of the valve body two 20 corresponding to the input end of the newly added pipe burst section is started again, which drives the ball valve two 21 to rotate counterclockwise by 90° again, changing from the "┥" shape to the "丅" shape, and the channel of the spare pipe body 35 switches to the horizontal connection state. The medium flows into the adjacent spare pipe body 35 through the horizontal channel, and repeats the process of "flow sensor 2301 triggering - ball valve two 21 switching - medium flowing back to the pipeline body 1" to achieve continuous diversion for multiple pipe bursts.

[0054] Simultaneously, during the emergency diversion of the burst pipe, the marking component is activated to help maintenance personnel pinpoint the leak location. Specifically, the controller activates the motor B32 inside the slide B27, and the output of motor B32 drives gear B33 to rotate. Since gear B33 meshes with rack B34 on the top of mounting plate 2, slide B27 moves along slide groove 30 towards the burst pipe location, achieving precise positioning through coordinate signals fed back by composite belt 3. When slide B27 moves to the target position, motor B32 stops running. The electric push rod 28 at the end of the connecting rod 31 at the top of slide B27 is activated, and its output pushes fluorescent pen 29 towards marking plate 5. Fluorescent pen 29 leaves a bar mark on the marking plate 5 at the corresponding burst pipe location, making the leak location visible. At the same time, the alarm light 26 in the middle of mounting base 8 lights up, emitting a strong light alarm.

[0055] After receiving stress change signals, location information and alarm prompts from the system, the ground workstation arranges maintenance personnel to go to the site with tools. With the visual markings on the marker board 5 and the guidance of warning lights 19 and 26, the potential hazard area is quickly located. After the maintenance personnel complete the pipeline repair, they send a reset command through the controller. After all components are reset, the composite belt 3 resumes real-time monitoring, and the system returns to the initial standby mode, waiting for the next response command.
