[0002] Overhead transmission lines play a vital role in energy transmission and distribution. To meet the needs of high-voltage transmission, transmission lines are usually characterized by long spans, high erection heights, and wide cross-sections.

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figure 1-Figure 4 As shown, the friction-electromagnetic composite self-powered transmission line vibration detection device of an embodiment of the present invention includes: a shell component 1, a power generation component 2, an energy storage component (not shown in the figure) and a vibration detection component 3.

[0034] The housing assembly 1 is used to connect to the power transmission line. The housing assembly 1 has a cavity. The power generation assembly 2 is connected to the housing assembly 1 and is located in the cavity. The power generation assembly 2 includes a magnet portion 21 and a coil portion 22. The extension direction of the magnet portion 21 is parallel to the height direction of the housing assembly 1 (e.g., Figure 1 The coil portion 22 is aligned with the longitudinal direction of the housing assembly 1 (e.g. Figure 1The shell assembly 1 vibrates along the power transmission line, and one of the magnet portion 21 and the coil portion 22 is movable relative to the other of the magnet portion 21 and the coil portion 22 in the height direction of the shell assembly 1. The energy storage component is electrically connected to the power generation component 2, and the energy storage component is used to store the electric energy generated by the power generation component 2. The vibration detection component 3 includes a vibration detection part 31 and a host computer, the vibration detection part 31 is connected to at least one of the shell assembly 1 and the power generation component 2, the vibration detection part 31 is connected to the energy storage component, the vibration detection part 31 is electrically connected to the host computer, and the vibration detection part 31 is used to detect the vibration data of the power transmission line and transmit the vibration data to the host computer.

[0035] Specifically, if Figure 1-Figure 3 As shown, the upper end of the shell assembly 1 can be fixedly connected to the transmission line so that the shell assembly 1 can vibrate with the vibration of the transmission line. The extension direction of the magnetic part 21 is consistent with the up and down direction, so that the magnetic field generated by the magnetic part 21 itself extends roughly in the up and down direction. There are two coil parts 22, and the two coil parts 22 are symmetrically arranged relative to the magnetic part 21 in the left and right directions, so that when the shell assembly 1 vibrates with the transmission line, the coil part 22 and the magnetic part 21 move relative to each other to generate current. After the shell assembly 1 vibrates, the power generation component 2 can generate current and transmit it to the energy storage component, so that other electrical equipment of the detection device can use it, thereby realizing the self-powered function.

[0036] It is understood that because the vibration of the transmission line varies with the external environment, the energy storage assembly can store the electricity generated by the power generation assembly 2 even when the transmission line vibration is relatively low, thereby ensuring the normal operation of the vibration detection assembly 3. The vibration detection assembly 3 monitors the vibration of the transmission line in real time, promptly identifying potential safety hazards and improving the safety and reliability of the power grid.

[0037] It should be noted that the vibration detection unit 31 is responsible for collecting the vibration data of the power transmission line, and these data are transmitted to the host computer through electrical connection. The host computer is the center of data processing and user interaction, for receiving the vibration data transmitted by the vibration detection unit 31, processing, analyzing, and presenting the results to the user in the form of graphics, reports, etc. The host computer can also control the parameter settings of the vibration detection unit 31, and monitor the operating status of the entire system. Optionally, for the vibration detection of the power transmission line, the following equipment can be used: vibration sensor (such as accelerometer, velocity sensor, displacement sensor, etc.), optical fiber sensor, electromagnetic induction sensor, acoustic sensor, etc.

[0038] In other words, the friction-electromagnetic composite self-powered transmission line vibration detection device of the embodiment of the present invention can perform energy storage and vibration amplitude detection according to the difference in the amplitude of the transmission line. Among them, when the transmission line generates vibration, the magnet part 21 and the coil part 22 in the power generation component 2 move relative to each other, and the generated current is transmitted to the energy storage component for storage, so as to facilitate the provision of electric energy for other electrical equipment of the detection device. In addition, when the vibration amplitude of the transmission circuit exceeds a certain value, the vibration detection component 3 can use the vibration detection part 31 to detect and record the vibration amplitude data, and transmit the vibration amplitude data to the host computer for recording, so as to realize the self-power supply of the entire device and the vibration detection function of the transmission line. It is suitable for overhead transmission lines located in remote areas that cannot obtain external energy, and can be widely used in the field of vibration detection of overhead transmission lines.

[0039] Therefore, the friction-electromagnetic composite self-powered transmission line vibration detection device of the embodiment of the present invention does not require an external power supply, and can monitor the vibration of the transmission line in real time, promptly discover safety hazards, has strong environmental adaptability, and high overall stability.

[0040] In some embodiments, the shell assembly 1 includes a shell body 11 and a fixing frame 12, the fixing frame 12 is connected to the shell body 11 and is located in the cavity, the extension direction of the fixing frame 12 is consistent with the height direction of the shell body 11, one of the magnet portion 21 and the coil portion 22 is connected to the fixing frame 12 so as to move along the height direction of the shell body 11 on the fixing frame 12, and the other of the magnet portion 21 and the coil portion 22 is connected to the shell body 11. There are multiple fixing frames 12, and the multiple fixing parts are arranged at intervals along the circumference of the magnet portion 21.

[0041] Specifically, if Figure 1-Figure 3 As shown, the housing body 11 comprises an upper housing 111, a lower housing 112, and housing side panels, providing protection and installation space for the internal components. The upper and lower ends of the fixing frame 12 are fixedly connected to the upper housing 111 and the housing, respectively, to support and guide the movement of the magnet portion 21 or the coil portion 22. Preferably, multiple fixing members are evenly spaced around the circumference of the magnet portion 21 so that the center of gravity of the entire housing assembly 1 coincides with the center, ensuring the stability of the vibration effect of the housing assembly 1.

[0042] It is understood that the magnet portion 21 can be connected to the fixing bracket 12, while the coil portion 22 is fixedly connected to the housing body 11. Then, when the transmission line vibrates, the magnet portion 21 moves relative to the coil portion 22, thereby achieving power generation. Conversely, the coil portion 22 can be connected to the fixing bracket 12, while the magnet portion 21 is connected to the housing body 11. This also allows power generation when the transmission line vibrates.

[0043] like Figure 1-Figure 3As shown, the following embodiments all take the case where the coil portion 22 is fixedly connected to the housing body 11 as an example, and the magnet portion 21 is connected to the fixing frame 12 so as to be movable on the fixing frame 12 in the up and down directions.

[0044] In some embodiments, the housing assembly 1 further includes a movable frame 13 connected to the fixed frame 12 . The movable frame 13 is movable relative to the fixed frame 12 along the height direction of the housing body 11 . The magnet portion 21 is connected to the movable frame 13 .

[0045] It is understandable that if Figure 1-Figure 3 As shown, the movable frame 13 includes a movable rod 131, a movable top plate 132 and a movable bottom plate 133, wherein there are multiple movable rods 131, and the multiple movable rods 131 are connected in sequence to form a movable portion and are in a "well" shape. There are two movable portions and they are symmetrically arranged on the front and rear sides of the magnet portion 21 along the front and rear directions. The upper end of the movable rod 131 is connected to the movable top plate 132, and the lower end of the movable rod 131 is connected to the movable bottom plate 133. The left and right ends of the movable rod 131 are both matched with the fixed frame 12 through the shaft hole, so that the movable frame 13 as a whole can move up and down along the fixed frame 12.

[0046] It should be noted that the overall structure of the mobile frame 13 is symmetrically arranged, ensuring that the center of gravity of the entire detection device does not shift after the mobile frame 13 is connected to the fixed frame 12. Furthermore, the mobile frame 13 utilizes a rod structure, which not only ensures stable installation with the fixed frame 12 but also reduces the overall weight of the mobile frame 13, thereby improving the overall mechanical strength and reliability of the detection device and contributing to its long-term stable operation.

[0047] Optionally, there are multiple power generation components 2, and the multiple power generation components 2 are arranged in sequence along the width direction of the shell body 11. In the width direction of the shell body 11, the magnetic poles of two adjacent magnet parts 21 are opposite.

[0048] It is understandable that if Figure 1-Figure 3 As shown, there are multiple power generation components 2. The arrangement of multiple power generation components 2 enables the detection device to capture more vibration energy, that is, multiple power generation components 2 can work in parallel. Among them, multiple power generation components 2 can be connected in parallel or in series.

[0049] Connecting multiple power generation assemblies 2 in parallel can increase the total current and power generation. Specifically, the output voltage of all power generation assemblies 2 is the same, while the currents are added together to provide a higher total current output, suitable for loads requiring higher current or battery charging. This also improves system redundancy for the power generation assemblies 2. If one power generation assembly 2 fails, the other parallel assemblies can still operate normally, thus improving system reliability.

[0050] Connecting multiple power generation components 2 in series can reduce the impact of voltage changes in a single component on the overall system voltage, thereby improving voltage stability. Furthermore, since the current in each component is the same, the series connection can reduce losses caused by current flowing through the wires.

[0051] Thus, the design of multiple power generation components 2 increases the overall power generation capacity, enabling the device to generate more electricity to meet the energy consumption requirements of the vibration detection component 3. The staggered polarity layout enhances the magnetic field, improves electromagnetic conversion efficiency, and thus increases power generation efficiency. This layout also reduces interference between magnetic fields, allowing each power generation component 2 to operate independently and effectively.

[0052] In some embodiments, the housing assembly 1 further includes an elastic member 14 . The elastic member 14 is sleeved on the fixed frame 12 . In the height direction of the housing body 11 , the elastic member 14 is located between the housing body 11 and the movable frame 13 .

[0053] It is understandable that if Figure 1-Figure 3 As shown, two elastic members 14 can be arranged on one fixed frame 12, namely, one is located between the movable top plate 132 and the upper shell 111, and the other is located between the movable bottom plate 133 and the lower shell 112. In other words, when the movable frame 13 is moving, when the movable frame 13 moves toward the upper shell 111, the distance between the movable top plate 132 and the upper shell 111 becomes smaller and smaller, so that the elastic member 14 located above is compressed. Then, when the movable frame 13 moves toward the lower shell 112, the compressed elastic member 14 can release its elasticity, thereby facilitating the movement of the movable frame 13 toward the lower shell 112 and providing elastic force for the movement of the movable frame 13.

[0054] In some embodiments, the fixing frame 12 includes a fixing section 121 and a limiting section 122 . The limiting sections 122 are located at both ends of the limiting section 122 in the extension direction of the fixing frame 12 . The transverse area of the limiting section 122 is larger than the transverse area of the fixing section 121 .

[0055] It is understandable that if Figure 1-Figure 3 As shown, the limiting section 122 is located at the upper and lower ends of the fixed section 121. Since the cross-sectional area of the limiting section 122 is larger than the cross-sectional area of the fixed section 121, when the movable frame 13 moves toward the limiting section 122, there can be a certain distance between the movable frame 13 and the upper and lower shells 112, thereby avoiding collision between the movable frame 13 and the shell body 11 during vibration, and also avoiding the elastic member 14 from being compressed for a long time and resulting in a reduction in elasticity, thereby improving the service life of the detection device.

[0056] In some embodiments, in the height direction of the shell body 11, the vibration detection part 31 is located between the movable frame 13 and the shell body 11, and the vibration detection part 31 includes a first electrode member 311 and a second electrode member 312. The first electrode member 311 is connected to the movable frame 13, and the second electrode member 312 is connected to the shell body 11, and the sum of the thickness of the first electrode member 311 and the thickness of the second electrode member 312 is greater than the thickness of the limiting section 122.

[0057] Specifically, if Figure 1-Figure 3 As shown, the vibration detector 31 is located between the moving member and the housing 11. This detector is directly associated with the displacement generated by vibration and can monitor the displacement changes of the moving member in real time. The vibration detector 31 includes a first electrode 311 and a second electrode 312. The contact and separation between the first and second electrodes 311, 312 generates a current, which is used to reflect the vibration of the transmission line.

[0058] It is understood that the first electrode member 311 is fixed to the movable frame 13 and thus moves with the movement of the movable frame 13. The second electrode member 312 is fixed to the housing body 11 and remains relatively stationary. The sum of the thicknesses of the first and second electrode members 311, 312 is greater than the thickness of the limiting section 122, ensuring that the first and second electrode members 311, 312 can contact each other during movement.

[0059] Optionally, there are multiple vibration detection parts 31, and the multiple vibration detection parts 31 are symmetrically arranged in the length direction of the shell body 11. It can be understood that, if Figure 1-Figure 3 As shown, the first electrode pieces of the multiple vibration detection parts 31 are respectively arranged on the movable top plate 132 and the movable bottom plate 133, and the second electrode pieces are respectively arranged on the upper shell 111 and the lower shell 112, so that when the movable frame 13 moves up and down, when it moves to the highest point and the lowest point, the vibration detection part 31 can detect the change of current through the contact between the first electrode piece 311 and the second electrode piece 312, thereby reflecting the change of the vibration amplitude of the transmission line.

[0060] The following describes a friction-electromagnetic composite self-powered transmission line vibration detection method according to an embodiment of the present invention.

[0061] The friction-electromagnetic composite self-powered transmission line vibration detection method of the embodiment of the present invention is performed using the friction-electromagnetic composite self-powered transmission line vibration detection device of any one of the above claims, comprising the following steps:

[0062] The current output of the energy storage component is monitored in real time, and the vibration of the transmission line is preliminarily determined based on the current output changes. It is understood that the current output is monitored in real time by a current sensor installed on the energy storage component. The current sensor converts the current signal into a voltage signal, which is then fed into the data acquisition unit. By monitoring the current output changes, the vibration of the transmission line can be preliminarily determined, as vibration can cause the power generation component 2 to generate varying amounts of electrical energy, which in turn affects the current output of the energy storage component.

[0063] The power generation component 2 provides the vibration detection component 3 with the required electrical energy. When the vibration amplitude of the transmission line reaches a preset value, the vibration detection unit 31 can transmit the detected vibration data to the host computer. It is understood that the power generation component 2 generates electrical energy through electromagnetic induction or frictional generation and transmits the electrical energy to the energy storage component. The energy storage component stores the electrical energy and supplies power to the vibration detection component 3 when needed.

[0064] When the vibration amplitude of the transmission line reaches a preset value, the electrodes of the vibration detection unit 31 come into contact or displace, thereby generating an electrical signal. The data acquisition unit collects these signals and sends them to the host computer via wireless or wired communication.

[0065] The host computer is used to plot the vibration amplitude versus time relationship based on the vibration data. As can be understood, after receiving the vibration data, the host computer uses data processing software to analyze the data and plot the vibration amplitude versus time relationship. This graph helps engineers or maintenance personnel intuitively understand the vibration conditions of the transmission line. The graphical display of vibration data makes the vibration situation more intuitive and easy to understand, helping to quickly identify vibration patterns or abnormalities so that timely measures can be taken.

[0066] Thus, the friction-electromagnetic hybrid self-powered transmission line vibration detection method of the present invention utilizes a self-powered vibration detection device to achieve real-time monitoring and data analysis of transmission line vibration. This not only improves the safety and reliability of transmission lines, but also reduces maintenance costs and complexity. The graphical data display makes vibration conditions more intuitive and easy to understand, facilitating the rapid identification of vibration patterns or abnormalities.

[0067] In some embodiments, the friction-electromagnetic composite self-powered transmission line vibration detection method of the embodiment of the present invention further includes the following steps: calculating the average amplitude of the vibration amplitude per unit time to accurately determine the vibration condition of the transmission line.

[0068] It is understandable that if Figure 4As shown in the figure, according to the current output curve, the vibration frequency of the transmission line can be judged to be 15Hz by the number of cycles of the current output within 10s. Since the current output increases with the increase of the vibration amplitude, the vibration amplitude of the transmission line can be judged according to the average amplitude of the current output within 10s.

[0069] In other words, calculating the average vibration amplitude eliminates the influence of instantaneous vibration peaks on the judgment, providing a more stable vibration assessment. The average value reflects the overall vibration level of the transmission line per unit time, helping to more accurately judge the vibration condition of the transmission line and take timely measures to prevent potential safety hazards.
