DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0025] The galloping and aeolian vibration of power transmission lines not only threatens the safety of power grid, but also contains considerable mechanical energy. This provides a new way to solve the energy supply problem of monitoring system: through innovative electromechanical coupling design, the harmful mechanical energy widely existing and long ignored can be efficiently converted into electrical energy. This technical path aims to achieve the integration of vibration suppression and power generation, and the energy extraction process actively suppresses the conductor vibration, forming a virtuous cycle; at the same time, the generated electrical energy can power the front-end monitoring unit, thereby bridging the energy supply gap and fundamentally improving the autonomy and reliability of the system.

[0026] However, existing vibration suppression devices (such as damping hammers) only dissipate vibration energy as heat and do not utilize it; and traditional energy harvester structures often do not deeply integrate with vibration suppression needs, with single function and limited energy extraction efficiency. There is currently a lack of electromechanical coupling structures that can simultaneously achieve efficient energy recovery and effective vibration suppression in the context of power transmission line vibration, especially in the coordinated regulation and utilization of vibration energy flow.

[0027] To solve the above technical problems, the present application provides a kind of vibration energy extraction and vibration reduction of power transmission line collaborative implementation intelligent fittings, as shown in Figure 1 And Figure 2 As shown, it includes a device body 1 for installation on a power transmission line, the device body 1 includes: A housing 11; At least one electromagnetic vibration suppression and energy harvesting module 12 installed in the housing 11, the electromagnetic vibration suppression and energy harvesting module 12 includes a permanent magnet and a coil, the coil is sleeved outside the permanent magnet, the coil does not contact the permanent magnet, the permanent magnet can reciprocate relative to the coil along a first direction when the power transmission line vibrates, so that the coil induces current and generates electromagnetic damping force, the first direction is the extension direction of the center line of the coil; At least one triboelectric vibration suppression and energy harvesting module 13 installed in the housing 11, the triboelectric vibration suppression and energy harvesting module 13 includes a power generation unit, the power generation unit includes a first triboelectric power generation unit and a second triboelectric power generation unit arranged along a first direction, the first triboelectric power generation unit and the second triboelectric power generation unit can undergo periodic contact and separation motion when the power transmission line vibrates to realize triboelectric nanogenerator.

[0028] The power transmission line vibration energy extraction and vibration reduction synergistically realizes the intelligent fitting, comprising a device body 1 for being installed on the power transmission line, the device body 1 comprising a shell 11 and at least one electromagnetic vibration suppression and energy trapping module 12 and at least one triboelectric vibration suppression and energy trapping module 13 installed in the shell 11; when the power transmission line vibrates, the permanent magnet in the electromagnetic vibration suppression and energy trapping module 12 can reciprocate relative to the coil, thereby causing the change of the magnetic flux inside the coil, inducing the current in the coil, and generating the electromagnetic damping force, which can suppress the vibration of the power transmission line and convert the mechanical vibration of the power transmission line into the electric energy, thereby realizing the energy recovery and vibration suppression, and the first triboelectric power generation unit and the second triboelectric power generation unit in the triboelectric vibration suppression and energy trapping module 13 can realize the periodic contact and separation movement, realize the friction nanometer power generation, and generate the electrostatic force, which can suppress the vibration of the power transmission line and convert the mechanical vibration of the power transmission line into the electric energy, thereby realizing the energy recovery and vibration suppression. In the above intelligent fitting, the electromagnetic vibration suppression and energy trapping module 12 and the triboelectric vibration suppression and energy trapping module 13 can realize the friction-electromagnetic composite generator structure design, based on which, facing the power transmission line vibration scene, the integration of vibration suppression and energy capture can be realized, the problems that the existing vibration suppression devices (such as the anti-vibration hammer) can only dissipate the vibration energy in the form of heat energy and cannot be utilized, and the traditional energy trapping device has the single function, is not deeply integrated with the vibration suppression demand, and has the limited energy extraction efficiency can be overcome, the vibration suppression-energy trapping synergistic device can be realized, the vibration suppression can be realized through the single device, and the recovered energy can be supplied to the sensor network, and the two difficult problems of the power transmission line vibration control and the continuous power supply of the sensor network are solved.

[0029] In actual field complex environment, the micro wind vibration and the dance are two main vibration forms of the conductor of the power transmission line. Among them, the micro wind vibration has the characteristics of "wide frequency and small amplitude", and the dance shows "low frequency and large amplitude". Further analysis shows that the core feature of the micro wind vibration is "small amplitude", and its frequency distribution range is wide, so it can be divided into "low frequency and small amplitude" and "high frequency and small amplitude"; the core feature of the dance is "low frequency", and its amplitude change range is large, so it can be further divided into "low frequency and low amplitude" and "low frequency and high amplitude". The classification method takes the motion energy density as the core basis, and divides the vibration into low energy density and high energy density. The vibration energy harvesting and vibration reduction of the power transmission line provided by the application realizes the intelligent fitting of the vibration suppression and energy trapping mechanism which is more suitable for different vibration conditions. For low energy density vibration (such as "low frequency and small amplitude" of micro wind vibration and "low frequency and low amplitude" of dance), the friction electricity vibration suppression and energy trapping module 13 is more suitable for weak motion response because it is based on the working principle of the friction nanometer generator, and can realize effective energy trapping of weak environmental excitation; and for high energy density vibration (such as "high frequency and small amplitude" of micro wind vibration and "low frequency and high amplitude" of dance), the electromagnetic vibration suppression and energy trapping module 12 has better energy conversion efficiency because it is based on the working principle of the electromagnetic generator, and can realize cooperative vibration suppression based on the dissipation mechanism in the energy conversion process.

[0030] Based on this, the vibration energy harvesting and vibration reduction of the power transmission line provided by the embodiment of the application realizes the cooperative effect of wideband vibration energy collection and vibration suppression, integrates the electromagnetic vibration suppression and energy trapping module 12 and the friction electricity vibration suppression and energy trapping module 13, and synchronously realizes effective suppression of conductor vibration and high-efficiency capture of vibration energy through a single structure, thereby providing an integrated solution for vibration control and all-weather high-entropy energy collection of intelligent power transmission lines, having significant integrated advantages and functional synergy; in addition, based on the friction-electromagnetic composite generator mechanism, the friction electricity vibration suppression and energy trapping module 13 can fully exert the high response characteristic to low frequency and small amplitude vibration, and the electromagnetic vibration suppression and energy trapping module 12 can fully exert the high-efficiency conversion ability to high frequency vibration energy, thereby having wideband conductor vibration energy collection ability, so as to significantly widen the vibration energy capture band of the device and improve the adaptability and energy output stability of the device in a complex line vibration environment.

[0031] Specifically, as shown in Figure 3 The specific working process of the vibration energy harvesting and vibration reduction of the power transmission line provided by the embodiment of the application can be: When the power transmission line vibrates, in the low-frequency micro-amplitude vibration stage, the friction electricity vibration suppression and energy harvesting module 13 mainly dominates the energy conversion and vibration suppression, the first friction power generation unit and the second friction power generation unit periodically contact-separation mechanism generates high-voltage output and forms electrostatic force action, and the electromagnetic vibration suppression and energy harvesting module 12 only produces a weak response, so as to realize the coupling control of efficient collection of weak vibration energy and vibration suppression; and in the high-frequency or large-amplitude vibration stage, the electromagnetic unit and the friction electricity unit work cooperatively, wherein the electromagnetic unit plays a leading role, and the vibration suppression and energy harvesting module 12 based on the relative movement between the permanent magnet and the coil generates induced electric energy by cutting the magnetic induction lines, and at the same time generates electromagnetic damping force, thereby effectively suppressing the vibration of the power transmission line. The vibration energy harvesting and vibration reduction of the power transmission line are realized by the vibration suppression-energy harvesting integrated cooperative control mechanism of the intelligent fitting, which can realize adaptive response under different vibration modes, overcome the problems of energy unavailability of the traditional anti-vibration hammer, narrow frequency band of the traditional energy harvester and low energy collection efficiency, and realize comprehensive utilization and effective suppression of vibration energy under wide-frequency vibration conditions, so as to provide a stable and reliable self-power supply source for the power transmission line state monitoring equipment.
