Description

Technical Field

[0001] This invention belongs to the technical field of water pipeline maintenance equipment, and specifically relates to an intelligent monitoring and control device for long-distance water pipelines. Background Technology

[0002] In recent years, with the rapid development of water conservancy, the construction of high-flow, high-lift cascade water transfer pumping stations has been increasing, which can meet the demand for inter-basin water supply and reduce water pressure in water-scarce areas. Long-distance water transmission pipelines are an indispensable and important component of inter-basin water transfer projects. With the increase in high-head, high-flow discharge structures in water conservancy and hydropower projects, and the trend towards larger-scale and more complex projects, pipelines are more susceptible to hydraulic vibration and external environmental interference during operation. These interferences can manifest as vibrations of varying degrees, making pipeline vibration caused by water flow a more prominent problem.

[0003] Pipeline vibration can cause damage and even lead to the complete failure of water conservancy projects, posing a serious threat to economic benefits and even personal safety. The hazards caused by water pipeline vibration seriously affect normal production and life, and may even lead to accidents; the long-term vibration of pipelines poses hidden dangers to their safe operation, and the pipeline structure gradually accumulates damage, its durability continuously decreases, and in turn, safety accidents can occur.

[0004] Traditional vibration reduction methods are relatively simple, mainly relying on increasing pipe supports or changing piping, but their vibration reduction effect is limited and it is difficult to achieve precise control of vibration conditions. Summary of the Invention

[0005] In response to the problems of relatively simple traditional monitoring methods for pipeline vibration and difficulty in real-time monitoring of pipeline vibration, this invention provides an intelligent monitoring and control device for long-distance water transmission pipelines that can monitor pipeline vibration in real time, implement graded vibration reduction according to the corresponding vibration intensity, and provide timely warnings for abnormal vibration.

[0006] The solution adopted by the present invention to solve its technical problem is: a smart monitoring and control device for long-distance water transmission pipelines, wherein a front vibration monitoring device, an active and passive graded vibration reduction device and a rear vibration monitoring and alarm device are sequentially installed on the pipeline. The front vibration monitoring device and the rear vibration monitoring and alarm device both include a ring-shaped shell, a pipe perforation is provided in the center of the ring-shaped shell, and an even number of vibration sensors are evenly arranged on the inner ring wall of the ring-shaped shell.

[0007] An alarm device is also fixed to the outer side of the annular shell of the rear vibration monitoring and alarm device. The alarm device has a built-in buzzer and GPS locator. The real-time information obtained by the front vibration monitoring device and the rear vibration monitoring and alarm device is uploaded to the cloud through the Internet of Things data transmission module.

[0008] The active and passive graded vibration reduction device includes an annular shell. From the inside out, the annular shell contains a prefabricated layer of wave-damping and energy-absorbing material, an arc-shaped electromagnetic damping conductor, an arc-shaped magnetic field generator, and a protective insulating inner ring. The arc-shaped magnetic field generator comprises multiple electromagnets carrying current in the same direction, arranged in a circular ring around the center of the annular shell. The arc-shaped electromagnetic damping conductor is composed of multiple arc-shaped electromagnetic damping conductor sheets, with heat-insulating buffer material filling the spaces between adjacent arc-shaped electromagnetic damping conductor sheets. An annular prefabricated layer of wave-damping and energy-absorbing material is installed along the radial direction of the annular shell, closely adhering to the inner wall of the hollow ring core. This prefabricated layer directly contacts the inner wall of the annular shell's ring core and the electromagnetic damping conductor sheets. The annular shell also has a reserved connection port for connecting external cables.

[0009] Furthermore, both the circular outer shell and the ring-shaped housing are composed of two semi-cylindrical, topless, insulating outer shells joined together. The semi-cylindrical, topless, insulating outer shells are fixed together by pins. The circular outer shell is equipped with a monitoring device top cover of the same size, and the ring-shaped housing is equipped with a vibration damping device top cover of the same size. The top cover is fixed to the circular outer shell or the ring-shaped housing by pins.

[0010] The outer wall of the semi-cylindrical, topless insulating shell is uniformly provided with longitudinal pin holes, and the top cover is provided with pin holes corresponding to the pin holes. Thus, the pins pass through the pin holes to fix the top cover to the semi-cylindrical, topless insulating shell. The semi-circular cross-section of the semi-cylindrical, topless insulating shell extends to both sides with ear plates, and the ear plates are provided with pin holes. When two semi-cylindrical, topless insulating shells are spliced ​​together, the ear plates fit together and the pin holes face each other. Pins are inserted into the corresponding pin holes to fix the two semi-cylindrical, topless insulating shells into a ring-shaped shell or ring-shaped housing.

[0011] Furthermore, the arc magnetic field generator consists of four arc electromagnets. The four arc electromagnets are powered by an external power source. The coils on the arc electromagnets are wound in the same direction. The gaps between the four arc electromagnets are completely filled with vibration damping material, and the arc electromagnets are insulated from each other.

[0012] Furthermore, the arc-shaped electromagnetic damping conductor is composed of four arc-shaped electromagnetic damping conductor sheets arranged in a ring, and the arc-shaped electromagnetic damping conductor sheets are composed of multiple fan-shaped metal thin sheet conductors stacked in a plate-like heat sink arrangement.

[0013] Furthermore, the annular outer shell of the front vibration monitoring device and the rear vibration monitoring and alarm device is a hollow cylinder. An even number of inductive vibration sensors are evenly arranged along the circumference on the inner wall of the outer side of the annular outer shell. Sensor holes are correspondingly opened on the inner side of the annular outer shell so that the vibration sensors can directly contact the pipeline for monitoring.

[0014] Specifically, both the front vibration monitoring device and the rear vibration monitoring and warning device are equipped with four inductive vibration sensors.

[0015] Furthermore, the front vibration monitoring device and the rear vibration monitoring and warning device are equipped with Internet of Things (IoT) hardware modules.

[0016] The beneficial effects of this invention are:

[0017] (1) The intelligent monitoring and control device for long-distance water transmission pipelines has an even number of vibration monitoring sensors evenly installed in its vibration monitoring device to ensure the reliability of data monitoring. At the same time, it transmits the monitored vibration data to the cloud in real time, which facilitates further processing of the vibration data through database technology.

[0018] (2) The intelligent monitoring and control device for long-distance water transmission pipelines includes multiple vibration reduction measures. Among them, the prefabricated layer of wave-absorbing and energy-absorbing vibration reduction material is used as part of the passive vibration reduction. It has a long service life, simple maintenance, low price, and is easy to mass-produce. It is effective in dealing with sudden turbulent vibration and small vibration. The new wave-absorbing and energy-absorbing vibration reduction material can be superimposed with the active vibration reduction device in the intelligent monitoring and control device for long-distance water transmission pipelines to improve the vibration reduction effect.

[0019] (3) The intelligent monitoring and control device for long-distance water transmission pipelines includes multiple vibration reduction measures. In the normal passive vibration reduction mode, the device supplies a weak current to the arc magnetic field generator. The electromagnetic damping under the weak current works in conjunction with the prefabricated layer of wave-absorbing and energy-absorbing material to reduce pipeline vibration. It is highly responsive, can handle a wide range of vibration frequencies, and has a strong suppressive effect on sudden vibrations and initial small vibrations.

[0020] (4) The intelligent monitoring and control device for long-distance water transmission pipelines includes multiple vibration reduction measures. The principle of the active vibration reduction device is that the damping magnitude of the arc-shaped electromagnetic damping conductor in the magnetic field generated by different strong and weak currents is controllable. Moreover, the electromagnetic damping has a good vibration reduction effect and has the advantages of fast vibration reduction response and precise control of damping magnitude.

[0021] (5) The intelligent monitoring and control device for long-distance water transmission pipelines includes multiple vibration reduction measures. It has two graded vibration reduction modes: active vibration reduction and passive vibration reduction. It can solve abnormal vibration to the greatest extent while saving energy and increasing efficiency for different vibration levels. In addition, for some parts with average vibration reduction effect, we will focus on and install multiple sets of vibration reduction devices to achieve targeted protection.

[0022] (6) Intelligent monitoring and control device for long-distance water transmission pipelines. Among them, the intelligent alarm device uploads the pipeline vibration data after vibration reduction work to the cloud, and compares the pipeline vibration data before and after vibration reduction through big data technology to accurately evaluate the vibration reduction effect. At the same time, it can monitor the vibration of the pipeline in a timely manner and analyze it through big data technology. If abnormal vibration occurs, the system can automatically issue an alarm and mark it with GPS to facilitate relevant personnel to carry out inspection and maintenance.

[0023] (7) Intelligent monitoring and control device for long-distance water transmission pipelines. Among them, the intelligent alarm device can remotely monitor and manage the real-time vibration status of the pipeline through cloud data upload. Relevant personnel can view the vibration data and operation status of the pipeline at any time, so as to make timely adjustments to vibration reduction measures and ensure the safe and stable operation of the pipeline.

[0024] (8) The intelligent monitoring and control device for long-distance water transmission pipelines adopts a detachable design, which makes it easier to disassemble, inspect, maintain and replace, and facilitates customization and adaptation to different needs, thereby improving the reliability and versatility of the device.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below.

[0033] Example 1: The present invention provides an intelligent monitoring and control device for a long-distance water transmission pipeline 1. By uniformly installing the intelligent monitoring and control device on the water transmission pipeline 1, comprehensive monitoring and alarm of the long-distance water transmission pipeline 1 can be realized. Based on the magnitude of the monitored vibration, the device provides passive or active vibration reduction schemes for the vibration generated by the pipeline 1 during the water transmission process, thereby reducing the vibration of the pipeline 1.

[0034] like Figure 1 and Figure 2 As shown, a front vibration monitoring device 4, an active and passive graded vibration reduction device 2, and a rear vibration monitoring and warning device 3 are sequentially installed on pipe 1.

[0035] like Figure 3 As shown, the active and passive graded vibration reduction device 2 includes an annular shell 22. From the inside out, the annular shell 22 contains a prefabricated layer of wave-damping and energy-absorbing material 26, an arc-shaped electromagnetic damping conductor 25, an arc-shaped magnetic field generator 24, and a protective insulating inner ring 23. The arc-shaped magnetic field generator 24 includes multiple electromagnets carrying current in the same direction, arranged in a circular ring around the center of the annular shell 22. The arc-shaped electromagnetic damping conductor 25 is composed of multiple arc-shaped electromagnetic damping conductor 25 pieces, with heat-insulating buffer material filling the spaces between adjacent arc-shaped electromagnetic damping conductor 25 pieces. Along the radial direction of the annular shell 22, the annular prefabricated layer of wave-damping and energy-absorbing material 26 is installed close to the inner wall of the hollow ring of the annular shell 22. The prefabricated layer of wave-damping and energy-absorbing material 26 directly contacts the inner wall of the annular shell 22 and the electromagnetic damping conductor pieces. The annular shell 22 also has a reserved power connection port 27 for connecting external cables.

[0036] Specifically, the active and passive graded vibration damping device 2 has a detachable enclosed annular shell with an overall cylindrical shape. It is composed of two semi-cylindrical, topless, insulating shells fixed together by pins. One side has a circular hole in the middle for connecting an external cable. The top cover is disc-shaped and is fixed together with the two semi-cylindrical shells by pins. Its advantages are that the pin fixing facilitates disassembly and maintenance, and the detachable design makes it easier to customize and adapt to different needs, improving the reliability of the device.

[0037] The active and passive graded vibration damping device 2 features an arc-shaped magnetic field generator 24 evenly distributed around its center. This generator consists of four electromagnets with coils wound in the same direction of current, all evenly distributed around the center of the device, separated by insulating material. Its advantage lies in that when a constant-voltage stable current in the same direction is applied, the four electromagnets simultaneously generate magnetic fields of equal strength, which are then superimposed internally. This allows for more precise control of the magnetic field strength, resulting in accurate vibration damping, energy saving, and environmental protection. In the event of severe vibration, the vibration damping effect can be controlled by adjusting the magnitude of the constant-voltage stable current applied in the same direction, achieving active vibration damping. The four-part separation design effectively reduces the thermal effect of the current, extending the device's service life.

[0038] The active and passive graded vibration reduction device 2 has an internal arc-shaped electromagnetic damping conductor 25 composed of dozens of fan-shaped metal sheets stacked in a heat sink-like arrangement, corresponding to the arc-shaped magnetic field generator 24 on the inner side. The spaces between the four damping conductors are filled with wave-damping and energy-absorbing material. Its advantage lies in that when the vibrating electromagnetic damping conductor sheets vibrate in the pipe 1, they will displace along with the pipe 1. At this time, the electromagnetic damping conductor cuts magnetic field lines in the magnetic field generated by the arc-shaped magnetic field generator 24, generating an induced current and causing the conductor to receive an Ampere force in the magnetic field that opposes the displacement. The damping magnitude can be adjusted by changing the current magnitude, thereby achieving precise control of the vibration reduction effect. The heat sink-like stacked arrangement can effectively reduce the eddy current effect and lower the risk of local temperature rise. Simultaneously, this design can effectively reduce the size and weight of the device and improve reliability.

[0039] Its internal annular wave-damping and energy-absorbing vibration damping ring has a circular appearance and is made by casting wave-damping and energy-absorbing material through an annular mold. It is nested in the innermost core of a detachable closed annular shell. Its advantage lies in absorbing and dispersing vibration and impact energy, achieving a passive vibration reduction effect. It has excellent durability and stability, and can continuously and effectively perform vibration reduction and energy absorption under various environmental conditions.

[0040] The active and passive graded vibration reduction device 2 is equipped with active and passive two-stage vibration reduction measures, and sets different hazard level ranges for different vibration levels. The system adopts different vibration reduction measures for different hazard level ranges. Its advantage lies in graded treatment, precise vibration reduction, energy saving and high efficiency.

[0041] like Figure 4 and Figure 5As shown, both the front vibration monitoring device 4 and the rear vibration monitoring and warning device 3 include an annular housing 32. A pipe 1 is perforated at the center of the annular housing 32. An even number of vibration sensors are evenly arranged on the inner wall of the annular housing 32. In this embodiment, the front vibration monitoring device 4 is located on one side of the active / passive graded vibration reduction device 2 along the extension direction of the pipe 1. Its appearance is annular, and it houses an even number of vibration sensors connected to the Internet of Things (IoT) for data uploading to the cloud for unified control. Its advantage lies in the fact that the evenly arranged four vibration sensors, after uploading data to the cloud via IoT technology, can further classify, store, identify, and process the vibration data to form a database. This avoids the impact of random errors from a single sensor on monitoring, ensuring the effectiveness and reliability of the vibration monitoring data.

[0042] An alarm device is also fixed to the outside of the annular outer shell 32 of the rear vibration monitoring alarm device 3. The alarm device has a built-in buzzer and a GPS locator.

[0043] The front vibration monitoring device 4 and the rear vibration monitoring and warning device 3 are equipped with IoT hardware modules, which upload the real-time information obtained by the front vibration monitoring device 4 and the rear vibration monitoring and warning device 3 to the cloud through the IoT data transmission module.

[0044] The post-vibration monitoring and alarm device 3 is installed on the other side of the active and passive graded vibration reduction device 2 along the extension direction of the pipeline 1. Its internal vibration monitoring sensors 33 are arranged in the same manner as the vibration monitoring device, and transmit data to a cloud database in real time for identification and comparison. Its advantage lies in that staff can visualize, accurately grasp, and promptly adjust the effects of graded vibration reduction through cloud data processing and analysis. Externally, it is equipped with a buzzer alarm and a GPS positioning system, uploading real-time information to the cloud via IoT technology. By setting comparison thresholds before and after vibration reduction in the cloud, the buzzer will sound an alarm when abnormal data is detected, and the GPS positioning system will also mark the location in real time in the cloud, facilitating timely detection and intervention by staff.

[0045] Referring to the accompanying drawings, the method of using this invention is as follows: The front vibration monitoring device 4 and the rear vibration monitoring and warning device 3 are respectively placed at the front and rear positions of the active and passive graded vibration reduction device 2 to implement all-weather vibration detection and feedback on the vibration state of the pipeline 1. The front vibration monitoring device 4 monitors the initial condition of the pipeline 1 daily and collects relevant data and uploads it to the cloud. The rear vibration monitoring and warning device 3 is responsible for monitoring and evaluating the effect of vibration reduction. When the vibration data after vibration reduction is still within the threshold, the active and passive graded vibration reduction device 2 is in passive vibration reduction mode, mainly by the synergistic action of the wave-absorbing and energy-absorbing material prefabricated layer 26 and the arc-shaped electromagnetic damping conductor 25 under weak current to complete the vibration reduction; when the rear vibration monitoring and warning device 3 monitors and evaluates that the vibration monitoring data of the pipeline 1 after vibration reduction is still not within the threshold range, it will send a warning to the cloud, and the vibration reduction mode of the pipeline 1 will be switched to active vibration reduction mode through the cloud. At this time, when the pipeline 1 vibrates... The vibration is transmitted to the arc-shaped electromagnetic damping conductor 25, causing it to displace. This displacement, combined with the magnetic field generated by the arc-shaped magnetic field generator 24, cuts magnetic field lines, generating an induced current that subjects the conductor to an Ampere force that impedes displacement. This, along with the prefabricated energy-absorbing material layer 26, achieves a dual vibration reduction effect. If the data from pipe 1 remains abnormal after a period of time, the buzzer and GPS positioning module will send an alarm to the cloud and transmit a real-time GPS positioning signal. The buzzer will also sound an alarm, facilitating quick location of the problem area and subsequent handling by staff. When the vibration data from the current vibration monitoring device 4 and the subsequent vibration monitoring and alarm device 3 returns to normal, the cloud sends a command to stop the active vibration reduction module, reverting to passive vibration reduction mode, thus completing the vibration reduction work.

[0046] Example 2: Based on Example 1, the intelligent monitoring and control device for the long-distance water pipeline 1 is composed of two semi-cylindrical, topless, insulated shells, both the annular outer shell 32 and the annular shell 22. The semi-cylindrical, topless, insulated shells are fixed together by pins. The annular outer shell 32 is provided with a monitoring device top cover 31 of the same size, and the annular shell 22 is provided with a vibration damping device top cover 21 of the same size. The top cover is fixed to the annular outer shell 32 or the annular shell 22 by pins.

[0047] The outer wall of the semi-cylindrical, topless insulating shell is uniformly provided with longitudinal pin holes 29. The top cover is provided with pin holes corresponding to the pin holes 29, so that the pin passes through the pin holes to fix the top cover to the semi-cylindrical, topless insulating shell. The semi-circular cross section of the semi-cylindrical, topless insulating shell extends to both sides with ear plates 28. The ear plates 28 are provided with pin holes 29. When two semi-cylindrical, topless insulating shells are spliced, the ear plates 28 fit together and the pin holes 29 are opposite each other. The pins are inserted into the opposite pin holes 29 to fix the two semi-cylindrical, topless insulating shells into a ring-shaped shell 32 or a ring-shaped housing 22.

[0048] The arc magnetic field generator 24 in the active and passive graded vibration reduction device 2 consists of four arc electromagnets. The four arc electromagnets are powered by an external power source. The coils on the arc electromagnets are wound in the same direction. The gaps between the four arc electromagnets are completely filled with vibration reduction material, and the arc electromagnets are insulated from each other.

[0049] The active and passive graded vibration damping device 2 is also provided with a triangular support 5 on its lower side, which supports the active and passive graded vibration damping device 2 and the pipe 1 passing through it.

All other implementations obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
