Description

Technical Field

[0001] This invention relates to the field of pipeline leakage monitoring technology, and in particular to a pipeline leakage monitoring system using LoRa self-organizing network and power line carrier dual-mode transmission. Background Technology

[0002] During urban construction, in order to make the city more aesthetically pleasing, a large number of pipelines are installed underground. This makes it difficult to quickly detect pipeline leaks. Therefore, a pipeline leakage monitoring device is needed to monitor the pipeline network, so as to detect problems in the pipeline network in time and repair them quickly. Generally, pressure is detected to determine whether there is a pipeline leak.

[0003] Existing pipeline leakage monitoring systems typically rely on fans for direct cooling. However, since the devices are installed underground, soil and other contaminants can easily enter the system during cooling, affecting its operation. Furthermore, filters are insufficient to effectively protect against fine particles, hindering the system's functionality. Additionally, existing systems connect to pressure measurement points on the pipe section via a single thread, which is prone to loosening, leading to errors in pressure detection and further compromising the system's usability.

[0004] To address the aforementioned issues, we propose a pipeline leakage monitoring system based on dual-mode transmission of LoRa self-organizing network and power line carrier. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing a pipeline leakage monitoring system with LoRa self-organizing network and power line carrier dual-mode transmission.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pipeline leakage monitoring system based on LoRa self-organizing network and power line carrier dual-mode transmission, comprising: A fixed housing is provided, on which a wireless LoRa Mesh self-organizing network and a wired power line carrier communication module are fixedly installed. A sensing device is fixedly installed inside the fixed housing, and a connecting pipe is fixedly installed on the side wall of the fixed housing, and the connecting pipe is connected to the sensing device. The heat dissipation structure includes a heat dissipation cavity on a fixed outer shell. A heat-conducting plate corresponding to the sensing device is fixedly installed on the inner wall of the heat dissipation cavity. A mounting bracket is fixedly installed on the inner wall of the heat dissipation cavity. A motor is fixedly installed on the mounting bracket. A rotating rod is fixedly connected to the output end of the motor. A cooling fan is fixedly sleeved on the rotating rod. A mounting ring is slidably installed at the opening of the heat dissipation cavity. A filter screen is rotatably connected to the inner wall of the mounting ring. A vent hole penetrating the fixed outer shell is opened on the inner wall of the heat dissipation cavity. A cleaning structure is slidably installed on the rotating rod.

[0007] In the aforementioned pipeline leakage monitoring system using LoRa self-organizing network and power line carrier dual-mode transmission, the cleaning structure includes a fixed rod slidably sleeved on a rotating rod. The fixed rod passes through a filter screen and is rotatably connected to the filter screen. A cleaning plate is fixedly installed on the fixed rod, and the cleaning plate is in contact with the filter screen. An annular plate is fixedly connected to the filter screen. A fixing toothed ring is fixedly installed on the inner wall of the annular plate. A transmission structure is fixedly installed inside the heat dissipation cavity.

[0008] In the aforementioned pipeline leakage monitoring system using LoRa self-organizing network and power line carrier dual-mode transmission, the transmission structure includes a connecting plate fixedly connected to the inner wall of the heat dissipation cavity. A connecting sleeve is fixedly installed on the connecting plate. A lead screw and slider are fixedly connected to the inner wall of the connecting sleeve. A reciprocating lead screw is mechanically engaged with the lead screw and slider inside the connecting sleeve. The reciprocating lead screw passes through the connecting sleeve and is fixedly connected to a fixed gear. The fixed gear meshes with a fixed gear ring. The reciprocating lead screw and the fixed rod are connected by a synchronous belt transmission assembly. An adjusting plate is rotatably sleeved on the reciprocating lead screw, and the adjusting plate is slidably connected to the annular plate.

[0009] In the aforementioned pipeline leakage monitoring system using LoRa self-organizing network and power line carrier dual-mode transmission, an arc-shaped sliding block is fixedly installed on the adjustment plate, and an annular groove corresponding to the sliding block is opened on the annular plate.

[0010] In the aforementioned pipeline leakage monitoring system using LoRa self-organizing network and power line carrier dual-mode transmission, a heat-insulating protective shell is fixedly installed on the outside of the motor, and the heat-insulating protective shell is fixedly connected to the mounting bracket.

[0011] In the aforementioned pipeline leakage monitoring system using LoRa self-organizing network and power line carrier dual-mode transmission, the connecting pipe is fitted with an internally threaded pipe, and a sealing gasket is fixedly installed on the inner wall of the internally threaded pipe, with the direction of the internally threaded pipe thread being opposite to the direction of the connecting pipe thread.

[0012] In the aforementioned pipeline leakage monitoring system using LoRa self-organizing network and power line carrier dual-mode transmission, a display screen is fixedly installed on the fixed housing, and operation buttons are also fixedly installed on the fixed housing.

[0013] In the aforementioned pipeline leakage monitoring system using LoRa self-organizing network and power line carrier dual-mode transmission, an installation block is fixedly installed on the side wall of the fixed housing, and an alarm is fixedly installed on the fixed housing.

[0014] Compared with existing technologies, the advantages of this pipeline leakage monitoring system based on LoRa self-organizing network and power line carrier dual-mode transmission are as follows: 1. The heat of the device is guided to the heat dissipation cavity through the heat conduction plate, and the heat conduction plate in the heat dissipation cavity dissipates heat. Even if small soil particles enter the heat dissipation cavity, they will not affect the operation of the device and will help the device to operate normally. 2. An internally threaded tube is fitted onto the connecting pipe, and the thread direction of the internally threaded tube is opposite to that of the connecting pipe. The two layers of threads provide a better self-locking effect, which can effectively prevent the connection between the device and the pressure measuring point of the pipe section from becoming loose, and is beneficial for pressure detection. 3. The filter screen can be cleaned by rotating the cleaning plate, rotating the filter screen in the opposite direction, and moving the filter screen up and down, so as to prevent debris on the ground from clogging the filter screen and affecting the heat dissipation of the device.

[0017] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] Reference Figures 1-6 A pipeline leakage monitoring system with LoRa self-organizing network and power line carrier dual-mode transmission includes a fixed shell 1. The fixed shell 1 is fixedly installed with wireless LoRa Mesh self-organizing network and wired power line carrier communication modules, which can cover the entire scene in terms of communication. The main and backup modules have sufficient redundancy to avoid communication problems. Moreover, the construction requires no additional wiring and does not affect the normal operation of the facility. The fixed shell 1 is fixedly installed with sensing devices, which are mainly piezoelectric leakage noise sensors, high-precision pressure transmitters and ultrasonic flow sensors. These sensors can detect data such as temperature, pressure and leakage sound waves of liquid in the pipeline, thereby judging and locating pipeline leakage. The side wall of the fixed shell 1 is fixedly installed with a connecting pipe 24, which is connected to the sensing devices to facilitate sensing. The heat dissipation structure includes a heat dissipation cavity 4 opened on the fixed outer shell 1. A heat conduction plate 5 corresponding to the sensing device is fixedly installed on the inner wall of the heat dissipation cavity 4. A mounting bracket 6 is fixedly installed on the inner wall of the heat dissipation cavity 4. There is no connection between the heat conduction plate 5 and the mounting bracket 6. The two are separate. A motor 7 is fixedly installed on the mounting bracket 6. A rotating rod 8 is fixedly connected to the output end of the motor 7. A cooling fan 11 is fixedly sleeved on the rotating rod 8. A mounting ring is slidably installed at the opening of the heat dissipation cavity 4. A filter screen 10 is rotatably connected to the inner wall of the mounting ring. A vent hole is opened on the inner wall of the heat dissipation cavity 4 to penetrate the fixed outer shell 1. A cleaning structure is slidably installed on the rotating rod 8. The heat-conducting plate 5 transfers the heat generated during the operation of the device into the heat dissipation cavity. At the same time, the motor 7 is started. The output end of the motor 7 drives the rotating rod 8 to rotate, causing the cooling fan 11, which is fixedly sleeved on the rotating rod 8, to rotate, allowing air to circulate and dissipate heat. Meanwhile, the heat dissipation cavity is separated from the equipment inside the device. When the air circulates, no water droplets, dirt particles or other debris will enter the device and affect its operation. The cleaning structure includes a fixed rod 9 that is slidably sleeved on the rotating rod 8. The fixed rod 9 passes through the filter screen 10 and is rotatably connected to the filter screen 10. A cleaning plate 12 is fixedly installed on the fixed rod 9 and is in contact with the filter screen 10. An annular plate 13 is fixedly connected to the filter screen 10. A fixed toothed ring 14 is fixedly installed on the inner wall of the annular plate 13. A transmission structure is fixedly installed inside the heat dissipation cavity 4. The rotation of the rotating rod 8 will cause the fixed rod 9, which is fixedly installed on the rotating rod 8, to rotate, which will drive the cleaning plate 12 to rotate together. When the cleaning plate 12 rotates, it can clean the surface of the filter screen 10. The transmission structure includes a connecting plate 17 fixedly connected to the inner wall of the heat dissipation cavity 4. A connecting sleeve 18 is fixedly installed on the connecting plate 17. A lead screw slider 20 is fixedly connected to the inner wall of the connecting sleeve 18. A reciprocating lead screw 19 is mechanically engaged with the lead screw slider 20 inside the connecting sleeve 18. The reciprocating lead screw 19 passes through the connecting sleeve 18 and is fixedly connected to a fixed gear 15. The fixed gear 15 meshes with a fixed gear ring 14. The reciprocating lead screw 19 and the fixed rod 9 are connected by a synchronous belt transmission assembly 16. An adjusting plate 21 is rotatably sleeved on the reciprocating lead screw 19. The adjusting plate 21 is slidably connected to the annular plate 13. An arc-shaped sliding block 22 is fixedly installed on the adjusting plate 21. An annular groove 23 corresponding to the sliding block 22 is opened on the annular plate 13. While connecting the adjusting plate 21 and the annular plate 13 together in the vertical plane, the adjusting plate 21 and the annular plate 13 can also move in annularly. Under the action of the synchronous belt drive assembly 16, the reciprocating screw 19 rotates together with the fixed rod 9, which drives the fixed gear 15 fixedly installed on the reciprocating screw 19 to rotate, causing the fixed gear ring 14 meshing with the fixed gear 15 to also rotate, driving the annular plate 13 and the filter screen 10 to rotate. Moreover, since the screw slider 20 is fixed, the rotation of the reciprocating screw 19 will cause it to move up and down, driving the adjusting plate 21 and the sliding block 22 to move up and down together, causing the filter screen 10 to move up and down accordingly. The rotation and movement work together to shake off the debris on the filter screen 10, achieving a better cleaning effect. Furthermore, the up and down movement of the filter screen 10 will drive the fixed rod 9 to move up and down, keeping the fixed rod 9 and the reciprocating screw 19 moving synchronously and avoiding motion interference. A heat-insulating protective shell is fixedly installed on the outside of the motor 7, and the heat-insulating protective shell is fixedly connected to the mounting bracket 6 to protect the motor 7; an internally threaded tube 25 is fitted on the connecting pipe 24, and a sealing gasket is fixedly installed on the inner wall of the internally threaded tube 25, and the direction of the thread of the internally threaded tube 25 is opposite to the direction of the thread of the connecting pipe 24. After the connecting pipe 24 is threadedly connected to the pressure measuring point of the pipe section, the internally threaded tube 25 is moved so that the internally threaded tube 25 is threadedly connected to the pressure measuring point of the pipe section from the outside. The opposite thread can play a better self-locking role and prevent the connection between the connecting pipe 24 and the pressure measuring point of the pipe section from becoming loose, which would affect the pressure detection. A display screen is fixedly installed on the fixed housing 1, and an operation button is also fixedly installed on the fixed housing 1. The alarm value of the device can be set by the operation button, and the display screen shows the specific screen during the setting process. A mounting block 2 is fixedly installed on the side wall of the fixed housing 1. The fixed housing 1 can be fixed to the inner wall of the valve well or pump room well by fixing bolts through the mounting block 2. An alarm 3 is fixedly installed on the fixed housing 1, and the alarm 3 sends out information to trigger an alarm.

[0019] In this invention, when the device is in use, the connecting pipe 24 is first threadedly connected to the pressure measuring point of the pipe section. Then, the internally threaded pipe 25 is moved so that it is threadedly connected to the pressure measuring point of the pipe section from the outside. The opposite thread provides a better self-locking effect, preventing the connection between the connecting pipe 24 and the pressure measuring point of the pipe section from becoming loose, which would affect the pressure detection. The liquid in the sensing device's pipeline is detected in real time. During this process, the heat-conducting plate 5 pours the heat generated during the device's operation into the heat dissipation cavity. At the same time, the motor 7 is started, and the output end of the motor 7 drives the rotating rod 8 to rotate, causing the cooling fan 11, which is fixedly sleeved on the rotating rod 8, to rotate as well, allowing air circulation for heat dissipation. Meanwhile, the heat dissipation cavity is separated from the equipment inside the device, preventing water droplets, dirt particles, and other debris from entering the device and affecting its operation. The rotation of the rotating rod 8 causes the fixed rod 9, which is fixedly installed on the rotating rod 8, to rotate as well, causing the cleaning plate 12 to rotate. When in motion, the surface of the filter screen 10 can be cleaned. Under the action of the synchronous belt drive assembly 16, the reciprocating screw 19 rotates together with the fixed rod 9, driving the fixed gear 15 fixedly installed on the reciprocating screw 19 to rotate as well. This causes the fixed gear ring 14 meshing with the fixed gear 15 to rotate as well, driving the annular plate 13 and the filter screen 10 to rotate. Since the screw slider 20 is fixed, the rotation of the reciprocating screw 19 will cause it to move up and down, driving the adjusting plate 21 and the sliding block 22 to move up and down together, causing the filter screen 10 to move up and down accordingly. The rotation and movement work together to shake off the debris on the filter screen 10, achieving a better cleaning effect. Moreover, the up and down movement of the filter screen 10 will drive the fixed rod 9 to move up and down, keeping the fixed rod 9 and the reciprocating screw 19 moving synchronously and avoiding motion interference. Finally, when the sensing device detects an abnormality, it will issue an alarm through the LoRa self-organizing network and power line carrier, so that maintenance personnel can carry out maintenance in a timely manner.
