[0002] In municipal construction and industrial production, pressure pipelines (such as PE gas pipelines and PE water supply pipelines) are key infrastructures for fluid transportation, and their safe and stable operation is directly related to the life of residents, industrial production and public safety. However, such pressure pipelines are prone to pipe explosion or leakage in the long-term use process due to the influence of various factors; specifically, the pipeline may be damaged due to external factors such as construction damage and third-party damage; or the pipeline strength may be reduced due to medium corrosion and aging, resulting in leakage.

[0003] Once the pipeline explodes or leaks, it is often not detected in time.

Moreover, when the problem occurs, it is difficult to find the underground leak point. At present, a large amount of manpower and material resources are mainly relied on for investigation, and the workers need to detect along the pipeline line step by step, and use various simple tools and experience to judge the leak point position.

[0015] 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.

[0017] 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.

[0018] 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.

[0031] The side wall of the mounting plate 2 is fixedly connected with a rack A16 near the top end, the top end of the sliding seat A15 is fixedly connected with a motor AA17, the output end of the motor AA17 is fixedly connected with a gear A18, and the gear A18 is engaged with the rack A16.

[0032] The bottom end of the sliding seat A15 is fixedly connected with a warning light 19, and when the composite belt 3 detects that the pipeline body 1 is abnormal, the controller controls the reinforcement assembly to start at the same time, and the warning light 19 is turned on synchronously.

[0033] The marking assembly comprises a sliding seat B27, an electric push rod 28 and a fluorescent pen 29, the side, away from the pipeline body 1, of the mounting plate 2 is provided with a sliding groove 30, the inside of the sliding groove 30 is slidably connected with the sliding seat B27 at equal intervals, the top end of the sliding seat B27 is fixedly connected with a connecting rod 31, the other end of the connecting rod 31 is fixedly connected with the electric push rod 28 parallel to the marking plate 5, and the output end of the electric push rod 28 is fixedly connected with the fluorescent pen 29 perpendicular to the marking plate 5.

[0034] The inside of the sliding seat B27 is fixedly connected with a motor B32, the output end of the motor B32 is fixedly connected with a gear B33, the top of the mounting plate 2 is fixedly connected with a rack B34, and the plurality of gears B33 are engaged with the rack B34.

[0035] The working principle of the pipeline with the leak monitoring and alarming function provided by the application is as follows: In the initial state of normal pipeline operation, all components are in the preset standby position, ensuring stable medium conveying and real-time monitoring capability, the reinforcement assembly and the marking assembly are in the standby state, the arc-shaped clamping plate 4 is in the open state away from the pipeline body 1, and the fluorescent pen 29 and the marking plate 5 are kept separated; the composite belt 3 wound on the outer wall of the pipeline body 1 continuously works in a state, real-time monitoring the stress change of the outer wall of the pipeline body 1 and synchronously transmitting data to the controller and the ground workstation; the protective layer 301 on the outer wall of the composite belt 3 simultaneously plays a protective role of anti-corrosion and anti-mechanical damage; the ball valve one 7 in all valve bodies one 6 is in a “ ” shape open state, completely connecting the adjacent two pipeline bodies one 1, and guaranteeing the smoothness of the main medium conveying channel; the ball valve two 21 in all valve bodies two 20 is also in a “ ” shape open state, connecting the adjacent standby pipe bodies 35, and the standby pipe bodies 35 are in a standby state; the arc-shaped plate 23 in the valve body two 20 is tightly attached to the sealing gasket 25 on one side of the support frame 22 under the action of the tension of the tension spring 24, so as to realize the initial sealing of the input end of the valve body two 20.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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 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 rotatably connected to the inside of the bottom input end of the valve body two 20, and the arc - shaped plate 23 fits 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 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°, making the ball valve two 21 change from the "丄" - shape to the "┥" - shape, and the internal channel of the valve body two 20 switches to the upward - connected state. The medium continues to flow, pushing the arc - shaped plate 23 symmetrically and rotatably connected to one side of the support frame 22 to rotate. At the same time, the tension spring 24 is stretched, and the medium flows upward through the ball valve two 21 after passing through this channel and enters the valve body one 6 installed at the output end of the 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.

[0040] If the pipeline body 1 adjacent to the output end of the 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 burst section is started, driving 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 burst section is started again, driving 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 horizontally - connected state. The medium flows into the adjacent spare pipe body 35 through the horizontal channel, repeating 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 bursts.

[0041] At the same time, in the emergency diversion of the burst pipe, the marking assembly is started to lock the leakage position for the maintenance personnel, specifically, the controller starts the motor B32 in the slide B27, and the motor B32 drives the gear B33 to rotate; since the gear B33 is engaged with the rack B34 on the top of the mounting plate 2, the slide B27 moves along the sliding groove 30 to the burst pipe position, and the accurate positioning is realized through the coordinate signal feedback of the composite tape 3; when the slide B27 moves to the target position, the motor B32 stops running; the electric push rod 28 at the end of the connecting rod 31 at the top of the slide B27 is started, and the output end pushes the fluorescent pen 29 to move to the direction of the marking plate 5, and the fluorescent pen 29 leaves a strip-shaped mark at the corresponding burst pipe position of the marking plate 5, realizing the visualization of the leakage position; at the same time, the alarm lamp 26 in the middle of the mounting seat 8 is lit, and a strong light alarm is issued.

[0042] After the ground station receives the stress change signal, position information and alarm prompt sent by the system, the maintenance personnel carries tools to the scene, and through the visual mark of the marking plate 5 and the guidance of the warning light 19 and the alarm lamp 26, the hidden danger area is quickly positioned; after the maintenance personnel completes the pipeline repair, the reset instruction is sent through the controller, all components are reset, the composite tape 3 returns to the real-time monitoring state, and the system returns to the initial standby mode, waiting for the next response instruction.
