Abstract
Description
Technical Field
[0001] This invention relates to the field of municipal engineering, and in particular to a device for monitoring and handling leaks in municipal pipeline networks. Background Technology
[0002] Municipal pipeline networks (such as water and gas supply networks) are the "lifeline" of a city. Over long-term use, these pipelines can leak due to aging, corrosion, and external damage, especially at the junctions of two pipe sections. Whether it's water or gas, a leak will lead to…
[0003] Resource waste and energy loss can lead to serious consequences such as road collapses and secondary disasters.
[0004] During the construction of existing municipal pipeline networks, pipe connections are typically located inside manholes, usually using simple welding or flange connections. This makes leaks at these joints highly susceptible to occur during use. Generally, alarms are installed to monitor for leaks at these joints and alert staff when a leak is detected. However, because the pipelines are buried underground, even after an alarm is triggered, it takes time for workers to discover and repair the leak. If the leak is large or the subsequent handling is delayed, it can still lead to energy losses or other consequences. Furthermore, relying solely on alarms and waiting for manual repairs without timely intervention is inefficient and fails to quickly locate the leak point. Summary of the Invention
[0005] In view of this, the present invention provides a municipal pipeline network leakage monitoring and handling device. The device is installed at the pipeline connection point and can monitor, alarm, and quickly handle leakage at the pipeline connection point, thereby reducing the risk of pipeline leakage.
[0006] To achieve the above objectives, the present invention provides a municipal pipeline network leakage monitoring and handling device, comprising two sets of connecting pipes, one end of which is joined together. The municipal pipeline network leakage monitoring and handling device includes a detection mechanism and an adjustment mechanism disposed at the joint of the two sets of connecting pipes. The detection mechanism includes a detection sleeve, a detection airbag, and a detection component mounted on the detection sleeve. The detection airbag is fixed to the inner wall of the detection sleeve. The two sets of connecting pipes are symmetrically inserted into the detection sleeve, and the detection airbag is fitted over the joint of the two sets of connecting pipes, sealing the joint. The detection component includes a controller and a pressure detection tube. The controller is fixed to the detection sleeve, and one end of the pressure detection tube is fixedly connected to the top of the detection airbag, and the other end is connected to a barometer in the controller, used to measure the gas pressure inside the detection airbag, thereby determining whether a leak has occurred.
[0007] The adjustment mechanism consists of two sets, symmetrically fixed on both sides of the detection sleeve. Each set includes a guide cylinder and a drive mechanism installed inside the guide cylinder, with the guide cylinder vertically mounted on the detection sleeve. Each set of adjustment mechanisms is equipped with a corresponding movable mechanism, which includes an annular support fitted on the detection sleeve, a guide support installed inside the guide cylinder, and two sets of connecting rods symmetrically arranged on the annular support. Guide grooves are symmetrically opened on both sides of the detection sleeve. The guide support is installed at the output end of the drive mechanism, with both ends extending out of the guide groove and connected to the annular support. One end of each connecting rod is hinged to the annular support, and the other end is hinged to the pipe wall of the corresponding side connecting pipe. In the event of a pipe leak, the drive mechanism controls the guide support to move along the guide groove in a direction away from the detection sleeve, and during the movement, the connecting rods pull the two sets of connecting pipes towards each other and tighten them.
[0008] A further technical solution of the present invention: The controller is equipped with an alarm, and the controller is connected to the control terminal of the drive mechanism of the two sets of adjustment mechanisms. The controller continuously reads and detects the pressure data inside the airbag. When the pressure value inside the airbag deviates from the preset stable range for a certain period of time, the alarm is triggered to sound an alarm. At the same time, the controller controls the drive mechanism of the two sets of adjustment mechanisms to work, and controls the movable mechanism to pull the two sets of connecting tubes to tighten each other.
[0009] A preferred technical solution of the present invention is as follows: the free end of each set of connecting pipes is provided with a docking mechanism for connecting to an external pipeline; the docking mechanism includes a docking base, a docking insert on one side of the docking base, and a docking flange on the other side of the docking base. The docking base is an annular base, and multiple docking rods are provided on the side of the docking base where the docking insert is provided. The multiple docking rods are distributed in an annular and equidistant manner along the periphery of the docking insert; multiple positioning holes are correspondingly opened on the end face of each set of connecting pipes and the docking structure. The number and position of the positioning holes match the docking rods and are distributed in an annular array. The outer diameter of the docking insert matches the inner diameter of the connecting pipe. The docking insert is fixedly inserted into the connecting pipe, and the multiple docking rods are inserted into the corresponding positioning holes.
[0010] A preferred technical solution of the present invention: The detection component further includes a positioning module, an air supply pump, and an air supply pipe. A connecting bracket is fixedly installed at the top of the outer side of the detection sleeve. A controller is fixedly installed at the top of the connecting bracket. The positioning module is fixedly installed at the top of the controller. The positioning module is used to locate the pipeline network position. The air supply pump is fixedly installed at the rear side of the controller. The output end of the air supply pump is connected to the detection airbag through the air supply pipe. The air supply pump inflates the detection airbag through the air supply pipe and provides a stable air pressure. The controller is signal-connected to the positioning module and the air supply pump.
[0011] The preferred technical solution of the present invention is as follows: the detection airbag is installed in the middle of the detection sleeve, and an annular support pad is provided on the inner wall of the detection sleeve at the position corresponding to the detection airbag. The support pad is fixedly set on the inner wall of the detection sleeve, and the detection airbag has an annular structure and is fixedly set on the inner wall of the support pad.
[0012] A preferred technical solution of the present invention is as follows: the driving mechanism includes a servo motor and a transmission screw. A connecting seat is fixedly provided on the detection sleeve. The servo motor is fixed on the connecting seat. The guide cylinder is sleeved outside the servo motor and fixedly connected to the connecting seat. The transmission screw is connected to the output end of the servo motor. Two sets of guide grooves are arranged along the length direction of the guide cylinder and are parallel to the transmission screw. The guide support is threaded outside the transmission screw. The servo motor controls the rotation of the transmission screw, thereby driving the guide support to move along the transmission screw.
[0013] The preferred technical solution of the present invention is as follows: the two sets of connecting pipes are respectively provided with shrinkage interfaces at their docking ends. The diameter of the shrinkage interface is smaller than the diameter of the support pad. After the two sets of connecting pipes are docked, the outer side of the shrinkage interface at the docking point of the airbag is detected, and the docking gap between the two sets of connecting pipes is completely sealed.
[0014] The preferred technical solution of the present invention is as follows: two sets of connecting shafts are symmetrically arranged on both sides of the annular support, and the two sets of connecting supports are rotatably connected to the two sets of connecting shafts respectively. The other end of each set of connecting rods extends to the end of the corresponding side connecting pipe near the docking mechanism and is hinged to the outer wall of the connecting pipe. Connecting wing plates are provided at the hinge connection points between the two sets of connecting pipes and the connecting rods respectively, and the connecting rods are rotatably connected to the corresponding connecting wing plates.
[0015] The preferred technical solution of the present invention is as follows: multiple docking positioning holes are equally spaced on the surface of the docking flange, and the docking flange is used to connect with other pipelines in the pipeline network.
[0016] By employing the above technical solution, the present invention has the following beneficial effects:
[0017] (1) The present invention is equipped with a detection mechanism and an adjustment mechanism. Through the cooperation between the detection airbag, the air pressure detection tube and the controller, the controller can quickly identify and locate the leak at the pipeline connection through real-time air pressure monitoring. At the same time, through the cooperation between the servo motor, the transmission screw and the moving mechanism, the adjustment mechanism can immediately drive the moving mechanism to make linear movement after detecting the leak, so that the two pipeline sections can be directly tightened at the connection interface under the drive. The device can realize automatic detection, accurate location and preliminary emergency intervention of the leak point through the linkage response of detection and adjustment, which effectively solves the technical problems of low efficiency and difficulty in location caused by the reliance on manual investigation in the traditional method.
[0018] (2) The present invention is equipped with a movable mechanism and a pipeline mechanism. Through the rotational connection between the connecting support rod and the connecting wing plate, the linear motion of the movable mechanism can be effectively converted into a pushing and pulling action on the pipeline mechanism. Through the opposite movement design of the pipe shrinking interface at the end of the pipeline mechanism, the two pipe sections can be directly tightened under the drive. The device can actively tighten the leak point through the mechanical transmission structure, and implement preliminary sealing at the same time as the alarm, which limits the further expansion of the leak, buys time for subsequent maintenance, and solves the technical problem of simply alarming but not being able to control the leak on-site in real time.
[0019] (3) The present invention is equipped with components such as docking mechanism and pipeline network mechanism. Through the plug-in relationship between docking rod and positioning hole, the docking mechanism can maintain stable connection when the pipeline network mechanism is adjusted and moved. Through the design of docking flange, the convenience and sealing of the connection between the device and the external pipeline network system are ensured. The device can realize independent monitoring and adjustment of the connection of specific pipe sections without affecting the overall connection stability and sealing of the pipeline. It improves the modularity and reliability of the leakage early warning and treatment system and solves the technical problem of rapid, accurate and non-interfering emergency treatment of interface leakage in complex pipeline network.

The detection airbag 107 fits precisely outside the joint of the two sets of connecting pipes 4, sealing the joint. Figure 8 As shown, the detection assembly includes a controller 103, a positioning module 104, an air pump 105, an air supply pipe 106, and a pressure detection pipe 108. A connecting bracket 102 is fixedly installed at the top of the outer side of the detection sleeve 100.

The air supply pipe 106 is connected to the detection airbag 107, and air is supplied to the detection airbag 107 through the air pump 105 and the air supply pipe 106. One end of the pressure detection pipe 108 is fixedly connected to the top of the detection airbag 107, and the other end of the pressure detection pipe 108 is connected to the barometer in the controller 103 and is used to measure the gas pressure inside the detection airbag 107.
[0034] In the embodiments, such as Figure 1 , Figure 3 and Figure 7As shown, the adjustment mechanism 2 includes a connecting seat 200, a guide cylinder 201, a servo motor 203, and a transmission screw 204. The connecting seat 200 is fixed on the detection sleeve 100, the servo motor 203 is fixed on the connecting seat 200, the guide cylinder 201 is sleeved on the servo motor 203 and fixedly connected to the connecting seat 200, one end of the transmission screw 204 is connected to the output end of the servo motor 203, and the other end is rotatably connected to the inner wall of the guide cylinder 201; guide grooves 202 are symmetrically provided on both sides of the guide cylinder 201, the two sets of guide grooves 202 are arranged along the length direction of the guide cylinder 201 and are parallel to the transmission screw 204; the movable mechanism 3 includes an annular support 300, a guide support 301, and symmetrically arranged on both sides of the annular support 300. Two sets of connecting rods 304 are provided. The guide support 301 has a threaded hole inside that matches the transmission screw 204. The guide support 301 is threaded onto the transmission screw 204, and both ends extend from the two sets of guide grooves 202 and are integrated with the annular support 300. Two sets of connecting shafts 303 are symmetrically provided on both sides of the annular support 300. The two sets of connecting supports 302 are rotatably connected to the two sets of connecting shafts 303 respectively. The other end of each set of connecting rods 304 extends to the end of the corresponding side connecting pipe 4 near the docking mechanism 5 and is hinged to the outer wall of the connecting pipe 4. Connecting wing plates 403 are provided at the hinge connection points between the two sets of connecting pipes 4 and the connecting rods 304 respectively. The connecting rods 304 are rotatably connected to the corresponding connecting wing plates 403.
[0035] In implementation, such as 1 and Figure 5 As shown, the docking mechanism 5 includes a docking base 500, a docking tube 502 disposed on one side of the docking base 500, and a docking flange 503 disposed on the other side of the docking base 500. The docking base 500 is an annular base. On the side of the docking base 500 where the docking tube 502 is disposed, multiple docking rods 501 are provided. The multiple docking rods 501 are distributed in an annular pattern at equal intervals along the periphery of the docking tube 502. The docking flange 503 is fixedly disposed on the outside of the docking base 500. Multiple docking positioning holes 504 are equally spaced on the disc surface of the docking flange 503. The docking flange 503 is used to connect with other pipelines in the pipeline network. Multiple positioning holes 402 are provided at the connection end of each set of connecting pipes 4 and docking structure 5. The number and position of the positioning holes 402 match the docking rods 501 and are arranged in a ring array. The outer diameter of the docking tube 502 matches the inner diameter of the connecting pipe 4. The docking tube 502 is fixedly inserted into the connecting pipe 4, and multiple docking rods 501 are inserted into the corresponding positioning holes 402. The docking ends of the two sets of connecting pipes 4 are respectively provided with shrinkage interfaces 401. The diameter of the shrinkage interface 401 is smaller than the diameter of the support pad 101. After the two sets of connecting pipes 4 are docked, the detection airbag 107 is sleeved on the outside of the shrinkage interface 401 at the docking point, and completely seals the docking gap of the two sets of connecting pipes 4.
[0036] The working process of the present invention: The detection mechanism 1 in the present invention serves as the sensing and central unit of the entire system. The detection airbag 107 is arranged in a ring inside. In the initial state, it is filled by the air supply pump 105 through the air supply pipe 106 and maintained at a stable reference pressure value. The airbag tightly wraps the inner side of the support pad 101, and the support pad 101 is firmly fixed to the tubular inner wall of the detection mechanism 1 body. The two connecting pipes 4 to be monitored are inserted into the detection mechanism 1 symmetrically from the left and right sides through the specially designed shrinking interface 401 at their end diameters, so that part of their pipe sections just pass through the space enclosed by the ring detection airbag 107. Therefore, the inner ring surface of the detection airbag 107 and the outer wall of the two connecting pipes 4 form a dynamic sealed contact interface. As the brain of the entire system, the controller 103 integrates a barometer that is connected to the inner cavity of the detection airbag 107 via a dedicated barometer tube 108. This allows it to continuously read the pressure data inside the airbag at a very high frequency and with high sensitivity. Any fluctuation in pressure value that deviates from the preset stable range will be recorded and analyzed by the controller 103 in real time. At the same time, the positioning module 104 installed at the top of the controller 103 works continuously to provide a precise spatial label for the absolute geographical coordinates of the device or its relative position relative to the digital model of the pipeline network. This location information and pressure data are bound and stored within the controller 103.
[0037] When the two monitored connecting pipes 4 leak media at their joint due to sealing aging, external damage, or other reasons, whether it is water, gas, or other fluid, the leaked material will generate a small but detectable impact force or pressure disturbance at the moment of ejection or seepage. Because the annular structure of the detection airbag 107 essentially seals the annular gap between it and the outer wall of the connecting pipe 4, the energy of the leaking medium after overflowing from the pipe interface will directly act on the wall surface of the detection airbag 107 surrounding that area. This action leads to a key change: the pressure balance inside the detection airbag 107, which was originally in a closed and stable pressure state, is broken. If the leaking medium is liquid or pressurized gas, its influx into the narrow space between the airbag and the pipe wall will generate a positive pressure impact. A shock causes the pressure inside the airbag to rise. If a leak causes the pressure in the associated system to drop, a negative pressure suction effect may also occur at the interface, leading to a decrease in the pressure inside the airbag. Regardless of whether the pressure fluctuation is positive or negative, its physical signal will be transmitted through the gas-filled medium inside the airbag to the barometer sensor of the controller 103 without attenuation and extremely quickly along the pressure detection tube 108. The intelligent algorithm preset in the controller 103 will analyze the received pressure signal in real time, filter out environmental noise interference, and accurately determine whether the current pressure fluctuation originates from a real pipeline interface leak event through threshold comparison or pressure change rate analysis. Once a valid leak is determined, the controller 103 immediately enters the early warning and response process.
[0038] In this invention, the response of controller 103 is a multi-threaded synchronous triggering process. The first thread is information recording and remote alarm. Controller 103 immediately packages the current timestamp, the precise geographical location information provided by the positioning module 104, and the level of the leakage event, and sends it to the remote monitoring center or the smart terminal of relevant management personnel through its integrated wireless communication module. This achieves second-level reporting of leakage events and precise spatial mapping, completely solving the core pain points of difficult and inefficient manual inspection and positioning. Almost simultaneously, the second thread of controller 103 is activated, namely, the local physical intervention mechanism is initiated. Controller 103 sends synchronous drive commands to the two sets of adjustment mechanisms 2 symmetrically installed on the front and rear sides of the detection mechanism 1.
[0039] The core power source of each adjustment mechanism 2 is the built-in servo motor 203. After receiving the start signal from the controller 103, the motor immediately starts to rotate in the preset direction and speed. The output shaft of the servo motor 203 is fixedly connected to a precision-machined transmission screw 204. Therefore, the rotational motion of the motor is directly converted into the rotational motion of the transmission screw 204 around its own axis. This transmission screw 204 passes through the guide cylinder 201 inside the adjustment mechanism 2. Its threaded section forms a precise threaded fit with the threaded hole on the guide support 301 inside a key component—the movable mechanism 3. The guide support 301 is firmly fixed to the inner wall of the movable mechanism 3. The movable mechanism 3 includes an annular support 300 fitted outside the guide cylinder 201. To ensure the accuracy and stability of the motion trajectory, two axially extending guide grooves 202 are symmetrically machined on the cylinder wall of the guide cylinder 201. The annular support 300 is equipped with a guide key or slider structure that cooperates with it, so that the annular support 300 can only slide linearly along the axial direction of the guide cylinder 201 and cannot rotate. Therefore, when the servo motor 203 drives the transmission screw 204 to rotate, since the movable mechanism 3 is restricted from rotating by the guide grooves 202, according to the principle of screw transmission, the guide support 301 meshing with the screw will drive the entire movable mechanism 3 to produce a precise linear displacement along the axial direction of the guide cylinder 201. The direction of this displacement is determined by the rotation direction of the servo motor 203. In the leakage response mode, the control... The controller 103 commands the servo motors 203 on both sides to rotate in a specific direction, thereby driving the movable mechanisms 3 on both sides to move in a certain direction simultaneously. The linear movement of the movable mechanism 3 is the key step in transmitting power to the connecting pipe 4. On the left and right sides of the outer wall of the movable mechanism 3, there are symmetrically fixed connecting supports 302. Each connecting support 302 is equipped with a freely rotatable connecting shaft 303 through a bearing. At the outer end of the connecting shaft 303, a sturdy connecting rod 304 is radially fixed. The other end of these connecting rods 304 is not rigidly fixed, but is connected to the connecting wing plates 403 symmetrically arranged on the outer wall of the connecting pipe 4 through a hinge or bearing connection to form a rotational connection. This design constitutes a set of efficient linear motion and rotation to linear motion conversion mechanism. When the moving mechanism 3 moves axially linearly under the drive of the servo motor 203, it drives the connecting support 302 on it to move together. The movement of the connecting support 302 forces the connecting wing plate 403, which is connected to it through the connecting shaft 303 and the connecting rod 304, to change position. Since the connecting rod 304 and the connecting wing plate 403 are rotatably connected, and the connecting wing plate 403 is fixed on the connecting pipe 4, the force exerted by the connecting rod 304 on the connecting wing plate 403 can be decomposed into axial and radial components. Under the ingenious geometric design, the swing of the connecting rod 304 is mainly converted into a strong axial tensile or thrust force on the connecting wing plate 403.
[0040] Taking the need to tighten the interface during leakage as an example, the controller 103 drives the movable mechanism 3 to move in a specific direction. Through the transmission of the connecting support rod 304, the resultant force acting on the connecting wing plate 403 of the connecting pipe 4 will push the two connecting pipes 4 to make precise opposite linear movements along the internal axis of the detection mechanism 1. When the connecting pipe 4 moves, the shrinkage interface 401 at its end slides in the annular space of the support pad 101. Due to the matching design of the inner diameter of the support pad 101 and the outer diameter of the shrinkage interface 401, the movement process is smooth and the guidance is precise. The opposite movement of the two connecting pipes 4 directly causes their original docking to be... The mechanical axial tightening reduces the gap at the end face or generates greater compression on the sealing element sandwiched between the end faces. This mechanical tightening can immediately and effectively physically squeeze the leak gap, significantly increasing the flow resistance of the leak path. In ideal conditions, it can even temporarily seal minor leaks. This process is fully automated. From the moment the pressure sensor captures the leak signal to the moment the connecting pipe 4 completes the tightening action, the time is extremely short. It realizes closed-loop automatic control from "sensing" to "execution", and implements crucial preliminary intervention before human intervention arrives at the scene, greatly suppressing the expansion of the leak and the occurrence of secondary disasters.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
