Description

Technical Field

[0001] This invention relates to vibration control, and more particularly to a self-powered vibration control and monitoring device using a surrounding steel rope. Background Technology

[0002] Hydraulic pipelines are a crucial component of hydraulic transmission systems, widely used in aerospace, oil transportation, and nuclear reactor components. However, hydraulic systems are susceptible to vibration due to internal fluid-structure interaction and external environmental factors, leading to problems such as damage and leakage. To extend the service life of hydraulic pipelines, conserve manpower and resources, reduce vibration amplitude, and implement real-time vibration monitoring, it is essential. Real-time monitoring allows for the timely detection of pipeline faults and leaks, preventing accidents. Traditional sensors are primarily powered by cables and batteries, but the harsh working environment of hydraulic pipelines makes cable laying inconvenient, and batteries have limited, unsustainable power and pollute the environment.

[0003] A search revealed that application publication number CN114659739A discloses a self-powered structure based on magnetic force and triboelectric effect, specifically comprising an outer unit, an upper unit, and a lower unit. The outer unit includes an upper magnetic plate and an annular protective shell. The upper unit includes a large-diameter hollow cylinder, a small-diameter hollow cylinder, and a movable magnetic column, all coated with a triboelectric material layer A. The lower unit includes an annular plate unit and a base unit. The annular plate unit includes a small-diameter annular plate, a medium-diameter annular plate, and a large-diameter annular plate, all coated with a triboelectric material layer B. The upper and lower units are interlocked through independent gaps. When the upper unit is subjected to axial vibration, it maintains a long-term, regular up-and-down sliding motion under the repulsive action of magnets with the same polarity, causing the triboelectric material layers A and B to rub against each other, thereby generating charge and voltage signals, achieving the purpose of generating electrical energy and vibration sensing.

[0004] However, this device is suitable for environmental monitoring in remote and complex environments, such as bridges, dams, offshore wind turbines, and the ocean. It is not applicable to hydraulic pipelines, and the device only has a monitoring function and cannot control the vibration of the pipeline. Therefore, how to simultaneously control the vibration of hydraulic pipelines and monitor their operating status in real time is of great significance for practical engineering. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art and provide a self-powered vibration control and monitoring device with a surrounding steel rope.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] According to one aspect of the present invention, a self-powered vibration control and monitoring device with a surrounding steel rope is provided for a hydraulic pipeline. The device includes a steel rope, a pulley bearing, a steel rope fixing and adjusting device, a mounting frame, an oscillator, a coil, a magnet, an energy management and controller, and a vibration sensor. The steel rope passes around the pulley bearing and is wound around the mounting frame through the steel rope fixing and adjusting device. The oscillator is constrained within the mounting frame by the steel rope passing through it. The coil is wound around the oscillator. The magnet is nested at both ends of the mounting frame. When the energy management and controller is installed on the hydraulic pipeline, it stores electrical energy and supplies it to the vibration sensor connected to it. The data collected by the vibration sensor is processed by the energy management and controller and then transmitted to a processing terminal for analysis.

[0008] As a preferred technical solution, the device is installed on at least one hydraulic pipeline.

[0009] As a preferred technical solution, the mounting frame includes an upper mounting frame and a lower mounting frame. The upper mounting frame is provided with a quick-installation slot, and the lower mounting frame is provided with a quick-installation hook. The quick-installation slot and the quick-installation hook are interlocked to fix the mounting frame to the hydraulic pipeline.

[0010] As a preferred technical solution, the pulley bearing is located at both ends of the mounting frame, and the mounting frame has protrusions on both sides. The protrusions are located inside the pulley bearing and have steel rope through holes evenly distributed on them.

[0011] As a preferred technical solution, there are at least four pulley bearings. The steel rope passes through the steel rope through hole and around the pulley bearing, and is divided into several segments of equal length by the pulley bearing, with each segment having the same tension.

[0012] As a preferred technical solution, the steel rope fixing and adjustment device includes a steel rope fixing plate, a steel rope fixing support, a steel rope fixing bolt, and a steel rope adjusting bolt. The steel rope fixing plate and the steel rope fixing support clamp the two ends of the steel rope together by the steel rope fixing bolt. By rotating the steel rope adjusting bolt, the tension of each section of the steel rope is controlled to be the same to adapt to different vibration frequencies of the hydraulic pipeline.

[0013] As a preferred technical solution, the steel rope restricts the axial movement of the vibrator along the hydraulic pipeline.

[0014] As a preferred technical solution, the oscillator and coil move along the y and z directions under the restoring force of the steel rope, and cut magnetic field lines in the magnetic field generated by the magnet, so that current is generated in the closed circuit. At the same time, when the coil moves in the magnetic field, the induced current will cause the conductor to be subjected to Ampere force and hinder the movement of the coil, i.e., electromagnetic damping. In this way, the vibration threshold of the hydraulic pipeline in the y and z directions under different excitation frequencies is reduced.

[0015] As a preferred technical solution, the energy management and controller converts the bidirectional irregular alternating current generated by the coil into unidirectional pulsating direct current and stores it in the battery.

[0016] As a preferred technical solution, the energy management and controller stores and processes the data collected by the vibration sensor and transmits it to the processing end. By analyzing and processing the data, it identifies the type and location of pipeline faults, thereby realizing the diagnosis and prediction of pipeline operating status.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1) This invention is a dual-purpose device that can both reduce the vibration of hydraulic pipelines and monitor the vibration of hydraulic pipelines in real time.

[0019] 2) This invention is both a vibration absorption unit and a power generation unit. By driving the oscillator to reciprocate between magnets through a steel rope, it not only reduces the radial vibration amplitude of the hydraulic pipeline and achieves wide-frequency vibration reduction, but also converts the harmful vibration energy of the hydraulic pipeline into electrical energy to power the sensor, collect the vibration energy and status information of the hydraulic pipeline, and improves the flexibility of power use and the performance of the device.

[0020] 3) The present invention has a simple and ingenious structure that is independent of the hydraulic pipeline; it has a high degree of integration and the device can perform energy processing, vibration monitoring and wireless transmission, realizing real-time monitoring of the vibration status of the hydraulic pipeline through self-powered power supply.

[0021] 4) This invention uses an electromagnetic induction generator mechanism, which improves energy harvesting efficiency. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0034] This invention provides a self-powered vibration control and monitoring device using a surrounding steel rope, which can reduce the vibration threshold of hydraulic pipelines under complex excitations. It converts the energy generated during hydraulic pipeline vibration into electrical energy to drive sensors, enabling real-time monitoring of the pipeline and improving its safety and reliability in harsh environments. The invention will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 1 As shown, the present invention is mainly used on hydraulic pipeline 1, including steel rope 2, pulley bearing 3, steel rope fixing and adjustment device 4, mounting frame 5, vibrator 6, coil 7, magnet 8, energy management and controller 9 and vibration sensor 10.

[0036] like Figure 2 and Figure 3As shown, the mounting frame 5 includes an upper mounting frame 50 and a lower mounting frame 51. At least four pulley bearings 3 are installed at both ends of the mounting frame 50 and the lower mounting frame 51, respectively. The mounting frame 5 inside the pulley bearings 3 has protrusions with steel rope through holes 52 evenly distributed around its circumference. The upper mounting frame 50 has a quick-installation slot 500, and the lower mounting frame 51 has a quick-installation hook 510. The quick-installation slot 500 and the quick-installation hook 510 interlock to fix the mounting frame 5. On the hydraulic pipeline 1, the steel rope 2 passes through the steel rope through hole 52 and wraps around the pulley bearing 3. It is tightened and fixed between the upper mounting frame 50 and the lower mounting frame 51 by the steel rope fixing and adjusting device 4. The steel rope 2 is divided into several segments of equal length by the pulley bearing 3, and the tension of each segment is the same. The vibrator 6 also has steel rope through holes 52 evenly distributed around its circumference. The steel rope 2 passes through the steel rope through holes 52 evenly distributed around the circumference of the vibrator 6 and fixes the vibrator 6 between the upper mounting frame 50 and the lower mounting frame 51. The coil 7 is wound on the vibrator 6. There are two magnets 8, which are nested at both ends of the mounting frame 5 respectively, and the opposite magnetic poles are installed opposite each other.

[0037] like Figure 4 As shown, the steel rope fixing and adjusting device 4 includes a steel rope fixing plate 40, a steel rope fixing support 41, a steel rope fixing bolt 42, and a steel rope adjusting bolt 43. The two ends of the steel rope 2 are clamped by the steel rope fixing plate 40 and the steel rope fixing support 41. The steel rope fixing bolt 42 fixes the steel rope 2. The steel rope 2 is evenly arranged along the circumference of the upper mounting frame 50 and the lower mounting frame 51. By turning the steel rope adjusting bolt 43, the tension of each section can be made the same to adapt to the different vibration frequencies of the hydraulic pipeline 1.

[0038] like Figure 5 As shown, the self-powered vibration control and monitoring device of the surrounding steel rope type provided by the present invention is installed on the hydraulic pipeline 1 at least once, and three are installed in the figure; during installation, multiple devices are arranged in an array along the axial direction of the hydraulic pipeline 1.

[0039] When a self-powered vibration control and monitoring device with a surrounding steel rope is in operation, if the hydraulic pipeline 1 vibrates under external excitation, the oscillator 6 and coil 7 move along the y and z directions under the restoring force of the steel rope 2. The oscillator 6 jumps back and forth between the magnets 8, cutting magnetic field lines within the magnetic field generated by the magnets 8, causing a change in the magnetic flux of the coil 7. The coil 7 generates electricity due to electromagnetic induction, producing current in the closed circuit. The bidirectional irregular alternating current generated by the coil 7 is converted into unidirectional pulsating direct current by the energy management and controller 9 and stored in the battery. The stored electricity is transmitted to the vibration sensor 10 for its use. At the same time, when the coil 7 moves in the magnetic field, the induced current causes the conductor to experience an Ampere force and hinders the movement of the coil 7, i.e., electromagnetic damping. In this way, the vibration threshold of the hydraulic pipeline 1 in the y and z directions under different excitation frequencies is reduced, achieving the effect of vibration reduction. When the hydraulic pipeline 1 vibrates, the vibrator 6 moves in the y and z directions. The vibration sensor 10 transmits the vibration data to the energy management and controller 9. The energy management and controller 9 stores and processes the data and transmits it to the processing end, such as a computer. By analyzing and processing the data, the type and location of pipeline faults are identified, thereby realizing the diagnosis and prediction of the pipeline's operating status, thus completing the self-powered real-time vibration monitoring.

[0040] This invention can utilize the energy generated by the vibration of the hydraulic pipeline 1 within a 360° radius in the yOz plane, responding to different excitation frequencies and thus improving energy harvesting efficiency. Furthermore, this invention uses a steel rope 2 to drive the oscillator 6 to reciprocate between magnets 8, causing the coil 7 to generate electricity through electromagnetic induction. This electricity is then continuously supplied to the vibration sensor 10 via the energy management and controller 9, facilitating rapid processing of the acquired signals and enabling self-powered vibration monitoring. In addition, this invention reduces the lateral vibration amplitude of the hydraulic pipeline 1 by moving the oscillator 6 within the yOz plane, achieving wideband vibration absorption at different excitation frequencies.

[0041] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
