Description

Technical Field

[0001] The present invention belongs to the technical field of disaster prevention and control equipment for power transmission lines, specifically the technical field of anti-vibration hammers, and in particular relates to a broadband intelligent anti-vibration hammer for power transmission lines and an optimization design method thereof. Background Art

[0002] Transmission lines are a core component of modern power systems, with large spans and highly flexible structures. This design allows transmission lines to span long distances, but also makes them vulnerable to external environmental influences. For example, when wind loads continuously act on the conductors, the conductors will produce high-frequency vibrations, which cause slight bending and deformation at the hanging point of the conductors. This repeated bending and deformation will cause fatigue damage to the conductors over time, gradually weakening the structural integrity and load-bearing capacity of the conductors, thereby shortening their service life.

[0003] According to the causes and forms of conductor vibration, conductor vibration can be divided into breeze vibration, sub-span vibration, dancing, ice shedding jump, transverse magnetic shock corona dancing, short circuit vibration, turbulent vibration, etc. Among these types of vibration, breeze vibration and dancing have a particularly prominent impact on equipment safety. Breeze vibration is a phenomenon in which resonance occurs due to the impact frequency of aerodynamic force being equal to a natural frequency of the tensioned conductor in the span. The necessary conditions for vibration are the uniformity of airflow and the constancy of its direction. When the energy given by the wind to the conductor is large enough, the vibration of the conductor can be maintained. This minimum wind speed value is called the lower limit value, which is generally 0.5m / s. The maximum wind speed that can still cause conductor vibration when the wind speed increases is called the upper limit value. Generally, the upper limit value of wind speed is 4-7m / s. When the upper limit value is exceeded, the conductor cannot vibrate.

[0004] For high-voltage lines, the installation height is higher. At this time, the airflow on the plane of the ground wire is less affected by the ground wire on the ground, and breeze vibration is more likely to occur; the greater the installation tension, the more serious the damage to the ground wire caused by the vibration.

[0005] In order to deal with this problem, anti-vibration hammers are widely used in conductor systems as a key auxiliary device. By absorbing the vibration energy of the conductor, the anti-vibration hammer can effectively reduce the amplitude of the conductor vibration, thereby significantly extending the service life of the conductor. The structure of the anti-vibration hammer usually includes a heavy hammer with a certain mass, a steel wire with high elasticity and high strength, and a wire clamp. The anti-vibration hammer is usually suspended on the conductor on both sides of the overhead line near the insulator and fixed to the conductor by a wire clamp. After the anti-vibration hammer is installed, it can produce a movement in the opposite phase to the conductor vibration, thereby eliminating or weakening the conductor vibration.

[0006] The specific working principle of the anti-vibration hammer is as follows: when the overhead line vibrates due to factors such as wind, the anti-vibration hammer moves up and down, and uses the inertia of the heavy hammer to generate internal friction in the steel strands to consume most of the vibration energy of the overhead line. The damping of the heavy hammer by the air consumes part of the energy, and the anti-vibration hammer wire clamp consumes and reflects part of the energy. According to the principle of energy balance, the energy consumption of the anti-vibration hammer reduces the intensity of wind vibration.

[0007] Different wire specifications and spacing will cause different vibration frequencies, and these frequency changes will affect the effect of the anti-vibration hammer. Due to different structures, weights, and sizes, various anti-vibration hammers have certain natural frequencies, and the natural frequencies are different. For example, the following: The Stoke type vibration damper has a cylindrical weight made of cast iron fixed at both ends of a high-strength steel strand. A pair of clamps are riveted in the middle of the steel strand to install the vibration damper on the conductor. According to the structural size of the weight, it has two natural frequencies.

[0008] The multi-frequency anti-vibration hammer uses hammers of different masses at both ends of the steel strand, and the suspension points are not of equal length from the two ends of the steel strand. Using this structure, four natural frequencies can be obtained, and the adaptable frequency is relatively wide. The heavy hammer is a U-shaped structure cast from cast iron to prevent the hammer from rubbing against the steel strand during high-frequency vibration.

[0009] Although the above anti-vibration hammers have multiple natural frequencies, the vibration characteristics are constantly changing during use, so the anti-vibration effect of the anti-vibration hammer is sometimes strong and sometimes weak, and the best anti-vibration effect cannot be achieved.

[0010] In the prior art, in order to increase the vibration-proof effect of the vibration-proof hammer, people have made improvements from multiple angles. For example, the prior art CN105337235B discloses an electromagnetic shock-proof electromagnetic shock-proof intelligent shock-proof hammer, which includes a vibration detection head installed at the front of the power cable and an intelligent shock-proof head installed at the rear of the power cable; the vibration detection head includes a clamp and at least two acceleration sensors installed in the clamp; the intelligent shock-proof head includes a clamp base and an annular vibration assembly installed around the front of the clamp base; the outer layer of the annular vibration assembly is an annular packaging shell, and the number of electromagnetic vibrators that is the same as the number of acceleration sensor groups is evenly installed in the annular packaging shell in the circumferential direction; the outer end of each electromagnetic vibrator is installed with an electromagnetic coil, and the inner end is installed on a magnetic ring; a guide tube is installed between the magnetic ring and the electromagnetic coil; a cylindrical magnet mover that is adsorbed and matched with the magnetic ring is slidably connected in the guide tube. The acceleration sensor of the shock-proof hammer has the characteristics of small size and light weight, can measure spatial acceleration, and multiple groups are used together to reflect the motion properties of the power cable, that is, the vibration of the power cable as comprehensively as possible, thereby providing real-time data for the processor. When the acceleration sensor measures the initial acceleration direction of the electric cable vibration, the signal is transmitted to the processor for processing, thereby controlling the on and off of the electromagnetic coil of the electromagnetic vibrator, so that the magnetic force generated by the electromagnetic coil is greater than the adsorption force of the magnetic ring, thereby adsorbing the cylindrical magnet mover; the movement of the cylindrical magnet mover causes the electromagnetic coil to be subjected to an instantaneous reaction force, and the reaction force causes the annular vibration component to produce a movement opposite to the vibration direction; the annular vibration component and the electric cable have opposite vibration phases and cancel each other out, thereby achieving the purpose of reducing vibration.

[0011] However, the above-mentioned shock-absorbing hammer needs to use electric energy, and it uses solar panels for power supply, which has the risk of power failure in rainy weather, at night, etc., and the solar panels also need to be maintained, which increases the difficulty of maintenance for overhead lines.

[0012] In addition, the prior art CN112952710A discloses an intelligent wire shockproof hammer, including a main control unit that detects the vibration frequency and amplitude of the wire and outputs a signal, and a mechanical vibration tuning unit that is electrically connected to the main control unit and is controlled by the output signal of the main control unit to reduce the vibration amplitude of the wire. The mechanical vibration tuning unit includes a shell connected to the wire, and damping elastic rods are provided on the opposite sides of the shell. The two damping elastic rods are parallel, and the damping elastic rods have good elasticity. A hammer body is provided at one end of the damping elastic rod away from the shell, and the resonant frequency adjustment nut moves along the length direction of the damping elastic rod, thereby changing the clamp between the hammer body and the frequency adjustment block, so that the length of the part of the damping elastic rod that can vibrate together with the wire changes, so that the vibration of the hammer body can better adapt to different vibration frequencies of the wire within a certain range, thereby better achieving the effect of wire shockproof.

[0013] Similarly, the shock-proof hammer is also powered by a solar power supply device, which has the risk of power failure in rainy weather, at night, etc., as well as the problem of difficulty in maintenance.

[0014] In addition, the prior art CN216290112U discloses an adjustable shockproof hammer for a high-voltage transmission line, comprising: a central fixing seat, a vertical screw rod is vertically arranged inside the central fixing seat, and vertical guide rods are symmetrically arranged in parallel on the left and right sides of the vertical screw rod; a fixed hook is arranged above the central fixing seat, and a fixed pressure buckle is arranged in the middle of the fixed hook. The shockproof hammer can be fixed on the required transmission line through the fixed hook on the central fixing seat, and the left and right sides of the central fixing seat are symmetrically arranged with rigid extension rods, and a counterweight hammer body is separately nested on the rigid extension rod on each side. When the transmission line vibrates, the counterweight hammer body and the rigid extension rod are driven to vibrate synchronously, and the inner end of the rigid extension rod is connected to the central adjustment frame through a telescopic sleeve to drive it to move up and down, so as to absorb the vibration energy through the buffer springs symmetrically arranged on the upper and lower sides of the central adjustment frame, so as to reduce the vibration of the transmission line and achieve the effect of anti-vibration. The compression adjustment frame arranged on the outside of the buffer spring can be moved to adjust the spacing to adjust the compression and elastic force of the buffer spring, and then adjust its overall buffer vibration amplitude and strength, so as to facilitate adjustment according to different transmission line requirements, which is more flexible and convenient to use.

[0015] However, the above-mentioned anti-vibration hammer uses a guide rod to limit the movement of the hammer head to only up and down movement. If the swing direction of the hammer head is slightly tilted, it may cause its movement to be unsmooth, thereby weakening its anti-vibration effect.

[0016] Furthermore, the current selection and installation of anti-vibration hammers mainly rely on the experience of engineers and lack systematic theoretical support. When choosing the installation position, counterweight and energy consumption frequency of the anti-vibration hammer, there is usually no clear calculation basis, which also makes it difficult for traditional design solutions to achieve the best anti-vibration effect. Summary of the invention

[0017] The technical problem solved by the present invention is that the anti-vibration hammer in the prior art cannot adapt to different vibration frequencies and different environmental conditions.

[0018] In order to solve the above technical problems, the present invention provides a broadband intelligent anti-vibration hammer for power transmission lines and an optimization design method thereof, which can maximize the energy absorption and vibration reduction effect of the anti-vibration hammer, fully extend the service life of the conductor, and provide a reference for the design and installation of anti-vibration hammers for power transmission lines.

[0060] Compared with the prior art, the anti-vibration hammer provided by the present invention has the following beneficial effects: 1. The wide-band intelligent vibration-damping hammer provided by the present invention is constructed by arranging a bending energy absorber inside the hammer head, one end of the bending energy absorber is connected to the steel strand, and the other end is connected to the hammer head through an adjusting device. The bending energy absorber is continuously compressed and stretched during the swinging process of the hammer head, so as to achieve the purpose of absorbing vibration and consuming energy.

The acceleration sensor can monitor the vibration of the hammer head and can indirectly monitor the load-bearing state of the wire.

[0061] 2. The broadband intelligent anti-vibration hammer provided by the present invention has an internal bending energy absorber designed as an outer spring steel plate and an inner spring steel plate. When the outer spring steel plate is continuously bent, the inner spring steel plate is driven to continuously shift to achieve friction energy consumption.

[0062] 3. The broadband intelligent anti-vibration hammer provided by the present invention has a friction layer between the outer spring steel plate and the inner spring steel plate to increase the friction area; in addition, the surface of the friction layer is a rough surface to further increase the friction force and improve the friction energy consumption efficiency.

[0063] 4. The wide-band intelligent anti-vibration hammer provided by the present invention has an adjusting spring arranged between the adjusting nut and the inner wall of the groove. The adjusting nut is squeezed by the rebound force of the adjusting spring to prevent the adjusting nut from loosening, thereby preventing the frequency of the vibration-absorbing hammer head from changing during use, thereby effectively ensuring that the anti-vibration effect is continuous and stable.

[0064] 5. The broadband intelligent anti-vibration hammer provided by the present invention has a counterweight groove arranged on the outer wall of the hammer head, and the counterweight can be added as needed, providing more options for frequency adjustment.

[0065] 6. The wide-band intelligent anti-vibration hammer provided by the present invention utilizes a wire clamp to clamp the wire, and then the anti-vibration hammer is installed on the wire. A steel strand cluster is connected below the wire clamp, and vibration-absorbing hammer heads provided by the present invention are arranged on both sides of the steel strand cluster. By utilizing the characteristic of the vibration-absorbing hammer head that can freely adjust the frequency, the anti-vibration hammer provided by the present invention can be suitable for wires with different vibration frequencies and different environmental conditions.

[0066] 7. The wide-band intelligent anti-vibration hammer provided by the present invention utilizes a steel strand cluster to connect the wire clamp and the vibration absorbing hammer head. The steel strand cluster includes two upper steel strands and one lower steel strand. During the vibration of the conductor, the steel strands rub against each other, and the friction energy dissipation principle is utilized to further enhance the vibration reduction and anti-vibration effect of the anti-vibration hammer. In addition, the steel strand cluster in the present invention increases the friction area and adjustability between the steel strands. The increase in friction area provides a stronger energy dissipation capacity. At the same time, the two ends of the lower steel strand are free ends. Without disassembling the hammer head, it is easy to replace the lower steel strand, thereby providing greater convenience and greater operability for the frequency adjustment of the anti-vibration hammer; it is also conducive to the maintenance of the anti-vibration hammer.

[0067] 8. The broadband intelligent anti-vibration hammer provided by the present invention has a wire clamp comprising an annular tentacle and an independent tentacle, and a lever block is arranged between the annular tentacle and the independent tentacle. The lever block is used to create a certain gap between the annular tentacle and the independent tentacle, and the annular tentacle and the independent tentacle are fastened with a fastening bolt, so that the annular tentacle can grasp the wire clamp and generate a pre-tightening force to effectively transmit vibration energy, and can still hold the wire tightly when the diameter of the wire is weakened.

[0068] In a second aspect, the present invention further provides a method for optimizing the design of a broadband intelligent anti-vibration hammer, which optimizes the design of the broadband intelligent anti-vibration hammer, comprising: S1. Measure the vibration angle of the transmission line hanging wire and maximum vibration frequency ; S2, setting the frequency of one of the vibration absorbing hammer heads to a first set value, setting the frequency of the other vibration absorbing hammer head to a second set value, and setting the overall frequency of the anti-vibration hammer when the vibration of the vibration absorbing hammer head is not considered to be a third set value; S3. After installing the anti-vibration hammer, measure the vibration angle at the hanging line again. When the re-measured vibration angle is less than the allowable vibration angle, the installation is completed. When the maximum vibration angle exceeds the allowable vibration angle, it should be measured again after adding a counterweight and keeping the anti-vibration hammer frequency unchanged, until the maximum vibration angle is less than the allowable vibration angle, the installation is completed.

[0069] In some embodiments, the vibration angle for: ; In the above formula, is the wavelength of the vibration wave, is the amplitude of the vibration wave at the measuring point, is the distance between the measuring point and the clamp entrance.

[0070] In some embodiments, the maximum vibration frequency for: ; In the formula, is the stiffness of the conductor system, The quality of the wire.

[0071] In some embodiments, the first setting value is 0.1 .

[0072] In some embodiments, the second setting value is 0.5 .

[0073] In some embodiments, the third setting value is 0.8 .

[0074] In some embodiments, re-measuring the vibration angle at the hanging line specifically includes: after installing the anti-vibration hammer, measuring the vibration angle at least once, and taking the maximum value as the re-measured vibration angle.

[0075] In some embodiments, a vibration angle of 10' is allowed.

[0076] In some embodiments, in step S3, a counterweight is added and the frequency of the anti-vibration hammer is kept unchanged. The specific method is: the mass of each counterweight block is 50g, and one counterweight block is added at a time. After adding the counterweight, the position of the adjusting nut is adjusted to ensure that the frequency of the anti-vibration hammer remains unchanged.

[0077] Compared with the prior art, the anti-vibration hammer optimization design method provided by the present invention has the following beneficial effects: The broadband intelligent anti-vibration hammer optimization design method provided by the present invention first measures the maximum vibration frequency and vibration angle of the wire near the hanging line, and adjusts the natural vibration frequency of the two vibration-absorbing hammer heads and the anti-vibration hammer as a whole to , and ; Then, the vibration angle is measured again after the frequency of the anti-vibration hammer is kept unchanged according to the counterweight to ensure that the maximum vibration angle is less than the allowable vibration angle, thereby maximizing the vibration reduction and energy absorption effect.

[0091] Broadband Intelligent Vibration-proof Hammer Embodiment 1 This embodiment provides a broadband intelligent anti-vibration hammer for power transmission lines, such as Figure 3 and Figure 4 As shown, it includes a wire clamp 1, a steel strand cluster 2 and a vibration absorbing hammer 3. The wire clamp 1 is connected to the middle of the steel strand cluster 2. A vibration absorbing hammer 3 is respectively arranged at both ends of the steel strand cluster 2. The structure of the vibration absorbing hammer 3 is as shown in FIG. Figure 1As shown, it includes a hammer head 3-1, a groove is arranged at one end of the hammer head 3-1, the inner bottom wall of the groove is connected to the steel strand cluster 2, and a bending energy absorber is arranged between the steel strand cluster 2 and the inner wall of the groove; one end of the bending energy absorber is connected to the steel strand cluster 2 through a fixing device 3-4, and the other end of the bending energy absorber is connected to the inner wall of the groove of the hammer head 3-1 through an adjusting device; the bending degree of the bending energy absorber can be adjusted by the adjusting device.

[0092] A bending energy absorber is arranged inside the hammer head 3-1. The bending energy absorber is in a curved shape. During the swinging process of the hammer head 3-1, the bending energy absorber bends inwards and stretches outwards, thereby absorbing the vibration energy of the conductor transmitted from the steel strand, thereby achieving an anti-vibration effect.

[0093] The bending degree of the bending energy absorber is adjusted through the adjusting device, and then the vibration frequency of the bending energy absorber is adjusted, so that the vibration absorbing hammer head has more resonance frequencies and a wider vibration reduction frequency band, and has better vibration absorption and vibration suppression effects.

[0094] The groove refers to a groove sunken on one end of the hammer head 3-1, and the shape of the groove can be square, circular, polygonal or other shapes. Therefore, the groove has multiple wall surfaces, the inner bottom wall of the groove refers to the wall surface that is not connected to the surface of the hammer head 3-1, and the inner side wall of the groove refers to the wall surface that is connected to the surface of the hammer head 3-1.

[0095] In addition, it can be understood that the steel strand cluster 2 can also be replaced by steel strands or other connecting components for connecting wire clamps and vibration-absorbing hammers, such as steel wire ropes, etc., and the equivalent replacement of the steel strand cluster 2 still falls within the protection scope of this embodiment.

[0096] The conductor is clamped by the wire clamp 1, and then the anti-vibration hammer is installed on the conductor. When the conductor vibrates in a breeze, the wire clamp 1 can transfer the vibration energy to the steel strand cluster 2 and the vibration absorbing hammer head 3. Energy consumption and vibration reduction are achieved through the friction, bending of the steel strand cluster 2 and the swinging, bending, friction of the vibration absorbing hammer head 3.

[0097] Embodiment 2 This embodiment provides a broadband intelligent anti-vibration hammer for power transmission lines, such as Figure 3 and Figure 4 As shown, it includes a wire clamp 1, a steel strand cluster 2 and a vibration absorbing hammer 3. The wire clamp 1 is connected to the middle of the steel strand cluster 2. A vibration absorbing hammer 3 is respectively arranged at both ends of the steel strand cluster 2. The structure of the vibration absorbing hammer 3 is as shown in FIG. Figure 1As shown, it includes a hammer head 3-1, a groove is arranged at one end of the hammer head 3-1, the inner bottom wall of the groove is connected to the steel strand cluster 2, and a bending energy absorber is arranged between the steel strand cluster 2 and the inner wall of the groove; one end of the bending energy absorber is connected to the steel strand cluster 2 through a fixing device 3-4, and the other end of the bending energy absorber is connected to the inner wall of the groove of the hammer head 3-1 through an adjusting device; the bending degree of the bending energy absorber can be adjusted by the adjusting device.

[0098] A bending energy absorber is arranged inside the hammer head 3-1. The bending energy absorber is in a curved shape. During the swinging process of the hammer head 3-1, the bending energy absorber bends inwards and stretches outwards, thereby absorbing the vibration energy of the conductor transmitted from the steel strand, thereby achieving an anti-vibration effect.

[0099] The bending degree of the bending energy absorber is adjusted through the adjusting device, and then the vibration frequency of the bending energy absorber is adjusted, so that the vibration absorbing hammer head has more resonance frequencies and a wider vibration reduction frequency band, and has better vibration absorption and vibration suppression effects.

[0100] The groove refers to a groove sunken on one end of the hammer head 3-1, and the shape of the groove can be square, circular, polygonal or other shapes. Therefore, the groove has multiple wall surfaces, the inner bottom wall of the groove refers to the wall surface that is not connected to the surface of the hammer head 3-1, and the inner side wall of the groove refers to the wall surface that is connected to the surface of the hammer head 3-1.

[0101] In addition, it can be understood that the steel strand cluster 2 can also be replaced by steel strands or other connecting components for connecting wire clamps and vibration-absorbing hammers, such as steel wire ropes, etc., and the equivalent replacement of the steel strand cluster 2 still falls within the protection scope of this embodiment.

[0102] The conductor is clamped by the wire clamp 1, and then the anti-vibration hammer is installed on the conductor. When the conductor vibrates in a breeze, the wire clamp 1 can transfer the vibration energy to the steel strand cluster 2 and the vibration absorbing hammer head 3. Energy consumption and vibration reduction are achieved through the friction, bending of the steel strand cluster 2 and the swinging, bending, friction of the vibration absorbing hammer head 3.

[0103] Based on the above technical solution, Figure 2 As shown, the bending energy absorber includes an outer spring steel plate 3-6, one end of which is connected to the steel strand through a fixing device 3-4, and the other end of which is connected to the inner wall of the groove of the hammer head 3-1 through an adjusting device. The outer spring steel plate 3-6 is curved.

[0104] The outer spring steel plate 3-6 itself is a plate-like member, which is bent into a curved shape by using the fixing device 3-4 and the adjusting device, and then installed between the steel strand and the inner wall of the groove of the hammer head 3-1. The outer spring steel plate 3-6 has a stretching tendency and also has a certain compression space. During the swinging process of the hammer head 3-1, the outer spring steel plate 3-6 bends inward and stretches outward, thereby absorbing the vibration energy of the conductor transmitted from the steel strand, thereby achieving an anti-vibration effect.

[0105] In addition, a micro acceleration sensor is set at the top of the spherical arc surface at one end of the hammer head 3-1, and the vibration characteristics of the hammer head 3-1 are affected by the vibration characteristics of the wire. The acceleration sensor uses MEMS (micro-electromechanical system) technology for self-powering and does not require an external power supply. And the acceleration sensor signal can be transmitted through a wireless communication module installed on the transmission tower, and the wireless transmission module is powered by a solar panel. Therefore, the performance status of the wire can be monitored by monitoring the acceleration of the hammer head, and the fatigue broken wire can be quickly identified.

[0106] Embodiment 3 This embodiment provides a broadband intelligent anti-vibration hammer for power transmission lines, such as Figure 3 and Figure 4 As shown, it includes a wire clamp 1, a steel strand cluster 2 and a vibration absorbing hammer 3. The wire clamp 1 is connected to the middle of the steel strand cluster 2. A vibration absorbing hammer 3 is respectively arranged at both ends of the steel strand cluster 2. The structure of the vibration absorbing hammer 3 is as shown in FIG. Figure 1 As shown, it includes a hammer head 3-1, a groove is arranged at one end of the hammer head 3-1, the inner bottom wall of the groove is connected to the steel strand cluster 2, and a bending energy absorber is arranged between the steel strand cluster 2 and the inner wall of the groove; one end of the bending energy absorber is connected to the steel strand cluster 2 through a fixing device 3-4, and the other end of the bending energy absorber is connected to the inner wall of the groove of the hammer head 3-1 through an adjusting device; the bending degree of the bending energy absorber can be adjusted by the adjusting device.

[0107] like Figure 2 As shown, the bending energy absorber includes an outer spring steel plate 3-6, one end of which is connected to the steel strand through a fixing device 3-4, and the other end of which is connected to the inner wall of the groove of the hammer head 3-1 through an adjusting device. The outer spring steel plate 3-6 is curved.

[0108] The outer spring steel plate 3-6 itself is a plate-like member, which is bent into a curved shape by using the fixing device 3-4 and the adjusting device, and then installed between the steel strand and the inner wall of the groove of the hammer head 3-1. The outer spring steel plate 3-6 has a stretching tendency and also has a certain compression space. During the swinging process of the hammer head 3-1, the outer spring steel plate 3-6 bends inward and stretches outward, thereby absorbing the vibration energy of the conductor transmitted from the steel strand, thereby achieving an anti-vibration effect.

[0109] The bending degree of the bending energy absorber is adjusted through the adjusting device, and then the vibration frequency of the bending energy absorber is adjusted, so that the vibration absorbing hammer head has more resonance frequencies and a wider vibration reduction frequency band, and has better vibration absorption and vibration suppression effects.

[0110] The groove refers to a groove sunken on one end of the hammer head 3-1, and the shape of the groove can be square, circular, polygonal or other shapes. Therefore, the groove has multiple wall surfaces, the inner bottom wall of the groove refers to the wall surface that is not connected to the surface of the hammer head 3-1, and the inner side wall of the groove refers to the wall surface that is connected to the surface of the hammer head 3-1.

[0111] In addition, it can be understood that the steel strand cluster 2 can also be replaced by steel strands or other connecting components for connecting wire clamps and vibration-absorbing hammers, such as steel wire ropes, etc., and the equivalent replacement of the steel strand cluster 2 still falls within the protection scope of this embodiment.

[0112] The conductor is clamped by the wire clamp 1, and then the anti-vibration hammer is installed on the conductor. When the conductor vibrates in a breeze, the wire clamp 1 can transfer the vibration energy to the steel strand cluster 2 and the vibration absorbing hammer head 3. Energy consumption and vibration reduction are achieved through the friction, bending of the steel strand cluster 2 and the swinging, bending, friction of the vibration absorbing hammer head 3.

[0113] Based on the above technical solution, Figure 2 As shown, the bending energy absorber also includes an inner spring steel plate 3-11, and the inner spring steel plate 3-11 is arranged on the inner side of the outer spring steel plate 3-6.

[0114] A friction layer 3-10 is provided between the outer spring steel plate 3-6 and the inner spring steel plate 3-11. The friction layer 3-10 is a steel sheet. The inner surface of the friction layer 3-10 is a rough surface, and / or the outer surface of the friction layer 3-10 is a rough surface. In this embodiment, both the inner surface and the outer surface of the friction layer 3-10 are rough surfaces.

[0115] The friction coefficient of the inner surface of the friction layer 3-10 is 0.35, and the friction coefficient of the outer surface of the friction layer 3-10 is 0.4.

[0116] The inner spring steel plate 3-11 and the friction layer 3-10 are not fixedly connected to the outer spring steel plate 3-6, but the inner spring steel plate 3-11 and the friction layer 3-10 are only placed inside the outer spring steel plate 3-6. In addition, the inner spring steel plate 3-11 and the friction layer 3-10 are not fixedly connected to other components. Therefore, the friction layer 3-10 and the outer spring steel plate 3-6 can slide with each other, and the inner spring steel plate 3-11 and the friction layer 3-10 can slide with each other. The inner spring steel plate 3-11 and the friction layer 3-10 are both plate-shaped parts. After placing the two in the bending space of the outer spring steel plate 3-6, the inner spring steel plate 3-11 and the friction layer 3-10 are bent. Therefore, the inner spring steel plate 3-11 and the friction layer 3-10 have a tendency to stretch outward, so the friction layer 3-10 can be close to the outer spring steel plate 3-6, and the inner spring steel plate 3-11 is close to the friction layer 3-10.

[0117] During the swinging process of the hammer head 3-1, the outer spring steel plate 3-6 is continuously compressed and stretched, driving the friction layer 3-10 and the inner spring steel plate 3-11 to be continuously compressed and stretched, and then the friction layer 3-10 and the outer spring steel plate 3-6, the friction layer 3-10 and the inner spring steel plate 3-11 are continuously displaced to realize friction energy consumption.

[0118] The friction layer 3-10 can increase the friction area, and the surface of the friction layer 3-10 is a rough surface, which further increases the friction force and improves the friction energy consumption efficiency.

[0119] Embodiment 4 This embodiment provides a broadband intelligent anti-vibration hammer for power transmission lines, such as Figure 3 and Figure 4 As shown, it includes a wire clamp 1, a steel strand cluster 2 and a vibration absorbing hammer 3. The wire clamp 1 is connected to the middle of the steel strand cluster 2. A vibration absorbing hammer 3 is respectively arranged at both ends of the steel strand cluster 2. The structure of the vibration absorbing hammer 3 is as shown in FIG. Figure 1 As shown, it includes a hammer head 3-1, a groove is arranged at one end of the hammer head 3-1, the inner bottom wall of the groove is connected to the steel strand cluster 2, and a bending energy absorber is arranged between the steel strand cluster 2 and the inner wall of the groove; one end of the bending energy absorber is connected to the steel strand cluster 2 through a fixing device 3-4, and the other end of the bending energy absorber is connected to the inner wall of the groove of the hammer head 3-1 through an adjusting device; the bending degree of the bending energy absorber can be adjusted by the adjusting device.

[0120] The conductor is clamped by the wire clamp 1, and then the anti-vibration hammer is installed on the conductor. When the conductor vibrates in a breeze, the wire clamp 1 can transfer the vibration energy to the steel strand cluster 2 and the vibration absorbing hammer head 3. Energy consumption and vibration reduction are achieved through the friction, bending of the steel strand cluster 2 and the swinging, bending, friction of the vibration absorbing hammer head 3.

[0121] like Figure 2As shown, the bending energy absorber includes an outer spring steel plate 3-6, one end of which is connected to the steel strand through a fixing device 3-4, and the other end of which is connected to the inner wall of the groove of the hammer head 3-1 through an adjusting device. The outer spring steel plate 3-6 is curved.

[0122] The outer spring steel plate 3-6 itself is a plate-like member, which is bent into a curved shape by using the fixing device 3-4 and the adjusting device, and then installed between the steel strand and the inner wall of the groove of the hammer head 3-1. The outer spring steel plate 3-6 has a stretching tendency and also has a certain compression space. During the swinging process of the hammer head 3-1, the outer spring steel plate 3-6 bends inward and stretches outward, thereby absorbing the vibration energy of the conductor transmitted from the steel strand, thereby achieving an anti-vibration effect.

[0123] The bending degree of the outer spring steel plate 3-6 is adjusted by the adjusting device, and then the vibration frequency of the bending energy absorber is adjusted, so that the vibration absorbing hammer head has more resonance frequencies and a wider vibration reduction frequency band, and has a better vibration absorption and vibration suppression effect.

[0124] The groove refers to a groove sunken on one end of the hammer head 3-1, and the shape of the groove can be square, circular, polygonal or other shapes. Therefore, the groove has multiple wall surfaces, the inner bottom wall of the groove refers to the wall surface that is not connected to the surface of the hammer head 3-1, and the inner side wall of the groove refers to the wall surface that is connected to the surface of the hammer head 3-1.

[0125] In addition, it can be understood that the steel strand cluster 2 can also be replaced by steel strands or other connecting components for connecting wire clamps and vibration-absorbing hammers, such as steel wire ropes, etc., and the equivalent replacement of the steel strand cluster 2 still falls within the protection scope of this embodiment.

[0126] like Figure 2 As shown, the bending energy absorber also includes an inner spring steel plate 3-11, and the inner spring steel plate 3-11 is arranged on the inner side of the outer spring steel plate 3-6.

[0127] A friction layer 3-10 is provided between the outer spring steel plate 3-6 and the inner spring steel plate 3-11. The friction layer 3-10 is a steel sheet. The inner surface of the friction layer 3-10 is a rough surface, and / or the outer surface of the friction layer 3-10 is a rough surface. In this embodiment, both the inner surface and the outer surface of the friction layer 3-10 are rough surfaces.

[0128] The friction coefficient of the inner surface of the friction layer 3-10 is 0.45, and the friction coefficient of the outer surface of the friction layer 3-10 is 0.5.

[0129] The inner spring steel plate 3-11 and the friction layer 3-10 are not fixedly connected to the outer spring steel plate 3-6, but the inner spring steel plate 3-11 and the friction layer 3-10 are only placed inside the outer spring steel plate 3-6. In addition, the inner spring steel plate 3-11 and the friction layer 3-10 are not fixedly connected to other components. Therefore, the friction layer 3-10 and the outer spring steel plate 3-6 can slide with each other, and the inner spring steel plate 3-11 and the friction layer 3-10 can slide with each other. The inner spring steel plate 3-11 and the friction layer 3-10 are both plate-shaped parts. After placing the two in the bending space of the outer spring steel plate 3-6, the inner spring steel plate 3-11 and the friction layer 3-10 are bent. Therefore, the inner spring steel plate 3-11 and the friction layer 3-10 have a tendency to stretch outward, so the friction layer 3-10 can be close to the outer spring steel plate 3-6, and the inner spring steel plate 3-11 is close to the friction layer 3-10.

[0130] During the swinging process of the hammer head 3-1, the outer spring steel plate 3-6 is continuously compressed and stretched, driving the friction layer 3-10 and the inner spring steel plate 3-11 to be continuously compressed and stretched, and then the friction layer 3-10 and the outer spring steel plate 3-6, the friction layer 3-10 and the inner spring steel plate 3-11 are continuously displaced to realize friction energy consumption.

[0131] The friction layer 3-10 can increase the friction area, and the surface of the friction layer 3-10 is a rough surface, which further increases the friction force and improves the friction energy consumption efficiency.

[0132] Embodiment 5 This embodiment provides a broadband intelligent anti-vibration hammer for power transmission lines, such as Figure 3 and Figure 4 As shown, it includes a wire clamp 1, a steel strand cluster 2 and a vibration absorbing hammer 3. The wire clamp 1 is connected to the middle of the steel strand cluster 2. A vibration absorbing hammer 3 is respectively arranged at both ends of the steel strand cluster 2. The structure of the vibration absorbing hammer 3 is as shown in FIG. Figure 1 As shown, it includes a hammer head 3-1, a groove is arranged at one end of the hammer head 3-1, the inner bottom wall of the groove is connected to the steel strand cluster 2, and a bending energy absorber is arranged between the steel strand cluster 2 and the inner wall of the groove; one end of the bending energy absorber is connected to the steel strand cluster 2 through a fixing device 3-4, and the other end of the bending energy absorber is connected to the inner wall of the groove of the hammer head 3-1 through an adjusting device; the bending degree of the bending energy absorber can be adjusted by the adjusting device.

[0133] The groove refers to a groove sunken on one end of the hammer head 3-1, and the shape of the groove can be square, circular, polygonal or other shapes. Therefore, the groove has multiple wall surfaces, the inner bottom wall of the groove refers to the wall surface that is not connected to the surface of the hammer head 3-1, and the inner side wall of the groove refers to the wall surface that is connected to the surface of the hammer head 3-1.

[0134] In addition, it can be understood that the steel strand cluster 2 can also be replaced by steel strands or other connecting components for connecting wire clamps and vibration-absorbing hammers, such as steel wire ropes, etc., and the equivalent replacement of the steel strand cluster 2 still falls within the protection scope of this embodiment.

[0135] like Figure 2 As shown, the bending energy absorber includes an outer spring steel plate 3-6, one end of which is connected to the steel strand through a fixing device 3-4, and the other end of which is connected to the inner wall of the groove of the hammer head 3-1 through an adjusting device. The outer spring steel plate 3-6 is curved.

[0136] like Figure 2 As shown, the bending energy absorber also includes an inner spring steel plate 3-11, and the inner spring steel plate 3-11 is arranged on the inner side of the outer spring steel plate 3-6.

[0137] A friction layer 3-10 is provided between the outer spring steel plate 3-6 and the inner spring steel plate 3-11. The friction layer 3-10 is a steel sheet. The inner surface of the friction layer 3-10 is a rough surface, and / or the outer surface of the friction layer 3-10 is a rough surface. In this embodiment, both the inner surface and the outer surface of the friction layer 3-10 are rough surfaces.

[0138] The friction coefficient of the inner surface of the friction layer 3-10 is 0.4, and the friction coefficient of the outer surface of the friction layer 3-10 is 0.45.

[0139] The inner spring steel plate 3-11 and the friction layer 3-10 are not fixedly connected to the outer spring steel plate 3-6, but the inner spring steel plate 3-11 and the friction layer 3-10 are only placed inside the outer spring steel plate 3-6. In addition, the inner spring steel plate 3-11 and the friction layer 3-10 are not fixedly connected to other components. Therefore, the friction layer 3-10 and the outer spring steel plate 3-6 can slide with each other, and the inner spring steel plate 3-11 and the friction layer 3-10 can slide with each other. The inner spring steel plate 3-11 and the friction layer 3-10 are both plate-shaped parts. After placing the two in the bending space of the outer spring steel plate 3-6, the inner spring steel plate 3-11 and the friction layer 3-10 are bent. Therefore, the inner spring steel plate 3-11 and the friction layer 3-10 have a tendency to stretch outward, so the friction layer 3-10 can be close to the outer spring steel plate 3-6, and the inner spring steel plate 3-11 is close to the friction layer 3-10.

[0140] The outer spring steel plate 3-6 itself is a plate-like member, which is bent into a curved shape by using the fixing device 3-4 and the adjusting device, and then installed between the steel strand and the inner wall of the groove of the hammer head 3-1. The outer spring steel plate 3-6 has a stretching tendency and also has a certain compression space. During the swinging process of the hammer head 3-1, the outer spring steel plate 3-6 bends inward and stretches outward, thereby absorbing the vibration energy of the conductor transmitted from the steel strand, thereby achieving an anti-vibration effect.

[0141] The bending degree of the outer spring steel plate 3-6 is adjusted by the adjusting device, and then the vibration frequency of the bending energy absorber is adjusted, so that the vibration absorbing hammer head has more resonance frequencies and a wider vibration reduction frequency band, and has a better vibration absorption and vibration suppression effect.

[0142] During the swinging process of the hammer head 3-1, the outer spring steel plate 3-6 is continuously compressed and stretched, driving the friction layer 3-10 and the inner spring steel plate 3-11 to be continuously compressed and stretched, and then the friction layer 3-10 and the outer spring steel plate 3-6, the friction layer 3-10 and the inner spring steel plate 3-11 are continuously displaced to realize friction energy consumption.

[0143] The friction layer 3-10 can increase the friction area, and the surface of the friction layer 3-10 is a rough surface, which further increases the friction force and improves the friction energy consumption efficiency.

[0144] Based on the above technical solutions, Figure 2 As shown, the bending energy dissipator also includes a first stopper, which is arranged on the inner side of the end of the outer spring steel plate 3-6 connected to the adjusting device. The bending energy dissipator also includes a second stopper 3-9, which is arranged on the inner side of the connection between the outer spring steel plate 3-6 and the fixing device 3-4.

[0145] The first stopper and the second stopper 3-9 may have the same structure or different structures. In this embodiment, the first stopper and the second stopper 3-9 have the same structure, and are both vertically arranged plates, and reinforcing ribs are arranged on the rear side of the plates. The first stopper and the second stopper 3-9 are used to restrict the inner spring steel plate 3-11 and the friction layer 3-10 from coming out of the outer spring steel plate 3-6. This design belongs to a defense mechanism. Under normal circumstances, the inner spring steel plate 3-11 and the friction layer 3-10 will not come out of the outer spring steel plate 3-6.

[0146] In addition, since the outer spring steel plate 3-6 has a certain length, and during the use of the vibration-absorbing hammer head, the friction layer 3-10 and the inner spring steel plate 3-11 are both curved, the friction force between the friction layer 3-10 and the outer spring steel plate 3-6 can prevent the friction layer 3-10 from falling off from the side of the outer spring steel plate 3-6, and the friction force between the inner spring steel plate 3-11 and the friction layer 3-10 can prevent the inner spring steel plate 3-11 from falling off from the side of the friction layer 3-10. Therefore, there is no need to set a limiting structure on the sides of the friction layer 3-10 and the inner spring steel plate 3-11.

[0147] Embodiment 6 This embodiment provides a broadband intelligent anti-vibration hammer for power transmission lines, such as Figure 3 and Figure 4 As shown, it includes a wire clamp 1, a steel strand cluster 2 and a vibration absorbing hammer 3. The wire clamp 1 is connected to the middle of the steel strand cluster 2. A vibration absorbing hammer 3 is respectively arranged at both ends of the steel strand cluster 2. The structure of the vibration absorbing hammer 3 is as shown in FIG. Figure 1 As shown, it includes a hammer head 3-1, a groove is arranged at one end of the hammer head 3-1, the inner bottom wall of the groove is connected to the steel strand cluster 2, and a bending energy absorber is arranged between the steel strand cluster 2 and the inner wall of the groove; one end of the bending energy absorber is connected to the steel strand cluster 2 through a fixing device 3-4, and the other end of the bending energy absorber is connected to the inner wall of the groove of the hammer head 3-1 through an adjusting device; the bending degree of the bending energy absorber can be adjusted by the adjusting device.

[0148] The groove refers to a groove sunken on one end of the hammer head 3-1, and the shape of the groove can be square, circular, polygonal or other shapes. Therefore, the groove has multiple wall surfaces, the inner bottom wall of the groove refers to the wall surface that is not connected to the surface of the hammer head 3-1, and the inner side wall of the groove refers to the wall surface that is connected to the surface of the hammer head 3-1.

[0149] In addition, it can be understood that the steel strand cluster 2 can also be replaced by steel strands or other connecting components for connecting wire clamps and vibration-absorbing hammers, such as steel wire ropes, etc., and the equivalent replacement of the steel strand cluster 2 still falls within the protection scope of this embodiment.

[0150] like Figure 2 As shown, the bending energy absorber includes an outer spring steel plate 3-6, one end of which is connected to the steel strand through a fixing device 3-4, and the other end of which is connected to the inner wall of the groove of the hammer head 3-1 through an adjusting device. The outer spring steel plate 3-6 is curved.

[0151] The bending energy absorber also includes an inner spring steel plate 3-11, and the inner spring steel plate 3-11 is arranged on the inner side of the outer spring steel plate 3-6.

[0152] A friction layer 3-10 is provided between the outer spring steel plate 3-6 and the inner spring steel plate 3-11. The friction layer 3-10 is a steel sheet. The inner surface of the friction layer 3-10 is a rough surface, and / or the outer surface of the friction layer 3-10 is a rough surface. In this embodiment, both the inner surface and the outer surface of the friction layer 3-10 are rough surfaces.

[0153] The friction coefficient of the inner surface of the friction layer 3-10 is 0.45, and the friction coefficient of the outer surface of the friction layer 3-10 is 0.4.

[0154] The inner spring steel plate 3-11 and the friction layer 3-10 are not fixedly connected to the outer spring steel plate 3-6, but the inner spring steel plate 3-11 and the friction layer 3-10 are only placed inside the outer spring steel plate 3-6. In addition, the inner spring steel plate 3-11 and the friction layer 3-10 are not fixedly connected to other components. Therefore, the friction layer 3-10 and the outer spring steel plate 3-6 can slide with each other, and the inner spring steel plate 3-11 and the friction layer 3-10 can slide with each other. The inner spring steel plate 3-11 and the friction layer 3-10 are both plate-shaped parts. After placing the two in the bending space of the outer spring steel plate 3-6, the inner spring steel plate 3-11 and the friction layer 3-10 are bent. Therefore, the inner spring steel plate 3-11 and the friction layer 3-10 have a tendency to stretch outward, so the friction layer 3-10 can be close to the outer spring steel plate 3-6, and the inner spring steel plate 3-11 is close to the friction layer 3-10.

[0155] The outer spring steel plate 3-6 itself is a plate-like member, which is bent into a curved shape by using the fixing device 3-4 and the adjusting device, and then installed between the steel strand and the inner wall of the groove of the hammer head 3-1. The outer spring steel plate 3-6 has a stretching tendency and also has a certain compression space. During the swinging process of the hammer head 3-1, the outer spring steel plate 3-6 bends inward and stretches outward, thereby absorbing the vibration energy of the conductor transmitted from the steel strand, thereby achieving an anti-vibration effect.

[0156] The bending degree of the outer spring steel plate 3-6 is adjusted by the adjusting device, and then the vibration frequency of the bending energy absorber is adjusted, so that the vibration absorbing hammer head has more resonance frequencies and a wider vibration reduction frequency band, and has a better vibration absorption and vibration suppression effect.

[0157] During the swinging process of the hammer head 3-1, the outer spring steel plate 3-6 is continuously compressed and stretched, driving the friction layer 3-10 and the inner spring steel plate 3-11 to be continuously compressed and stretched, and then the friction layer 3-10 and the outer spring steel plate 3-6, the friction layer 3-10 and the inner spring steel plate 3-11 are continuously displaced to realize friction energy consumption.

[0158] The friction layer 3-10 can increase the friction area, and the surface of the friction layer 3-10 is a rough surface, which further increases the friction force and improves the friction energy consumption efficiency.

[0159] like Figure 2 As shown, the bending energy dissipator also includes a first stopper, which is arranged on the inner side of the end of the outer spring steel plate 3-6 connected to the adjusting device. The bending energy dissipator also includes a second stopper 3-9, which is arranged on the inner side of the connection between the outer spring steel plate 3-6 and the fixing device 3-4.

[0160] The first stopper and the second stopper 3-9 may have the same structure or different structures. In this embodiment, the first stopper and the second stopper 3-9 have the same structure, and are both vertically arranged plates, and reinforcing ribs are arranged on the rear side of the plates. The first stopper and the second stopper 3-9 are used to restrict the inner spring steel plate 3-11 and the friction layer 3-10 from coming out of the outer spring steel plate 3-6. This design belongs to a defense mechanism. Under normal circumstances, the inner spring steel plate 3-11 and the friction layer 3-10 will not come out of the outer spring steel plate 3-6.

[0161] In addition, since the outer spring steel plate 3-6 has a certain length, and during the use of the vibration-absorbing hammer head, the friction layer 3-10 and the inner spring steel plate 3-11 are both curved, the friction force between the friction layer 3-10 and the outer spring steel plate 3-6 can prevent the friction layer 3-10 from falling off from the side of the outer spring steel plate 3-6, and the friction force between the inner spring steel plate 3-11 and the friction layer 3-10 can prevent the inner spring steel plate 3-11 from falling off from the side of the friction layer 3-10. Therefore, there is no need to set a limiting structure on the sides of the friction layer 3-10 and the inner spring steel plate 3-11.

[0162] Based on the above technical solutions, Figure 2 As shown, the specific structure of the fixing device 3-4 is a connecting block. The outer spring steel plate 3-6 is rigidly connected to the fixing device 3-4. The rigid connection can be welding, riveting, crimping and other connection methods. In this embodiment, welding is preferred. Among them, the connecting block is almost perpendicular to the steel strand. It can be understood that the connecting block can also be connected to the steel strand at other inclination angles without affecting the energy dissipation function of the bending energy absorber.

[0163] The adjusting device includes an adjusting bolt 3-5 and an adjusting nut 3-7. The adjusting bolt 3-5 is arranged on the inner wall of the groove of the hammer head 3-1, and one end of the outer spring steel plate 3-6 is passed through the adjusting bolt 3-5; the adjusting nut 3-7 is arranged on the adjusting bolt 3-5, and the adjusting nut 3-7 is located between the end of the bending energy absorber and the inner wall of the groove.

[0164] The outer spring steel plate 3-6 has a certain thickness. In order to facilitate the connection of the outer spring steel plate 3-6, one end of the outer spring steel plate 3-6 is thinned, and a hole is punched at the thinned end to realize the connection between the outer spring steel plate 3-6 and the adjusting bolt 3-5. In other embodiments, the adjusting bolt 3-5 can be equivalently replaced by a shaft with an external thread, and a step, a partially smooth surface, etc. can also be set on the shaft.

[0165] Since the outer spring steel plate 3-6 has a tendency to stretch outward, the upper end of the outer spring steel plate 3-6 has a tendency to move upward. An adjusting nut 3-7 is provided on the adjusting bolt 3-5 between the upper end of the outer spring steel plate 3-6 and the upper inner wall of the groove. The pre-tightening force of the adjusting nut 3-7 and the adjusting bolt 3-5 is utilized to limit the upper end of the outer spring steel plate 3-6 from moving upward, thereby changing its bending degree.

[0166] Among them, in other embodiments, the adjusting nut 3-7 can also be replaced by a flat plate-like structure or a non-flat plate-like structure with an internal threaded hole.

[0167] Furthermore, the adjusting bolt 3 - 5 and the upper inner wall of the groove may be arranged to be perpendicular or non-perpendicular.

[0168] In addition, the adjustment device also includes an adjustment spring 3-12, which is passed through the adjustment bolt 3-5, and one end of the adjustment spring 3-12 abuts against the inner wall of the groove, and the other end of the adjustment spring 3-12 abuts against the adjustment nut 3-7.

[0169] The adjusting spring 3-12 can be used to lock the adjusting nut 3-7 and the adjusting bolt 3-5, thereby preventing the adjusting nut 3-7 from loosening, thereby preventing the vibration-absorbing hammer head from changing in frequency during use, and effectively ensuring that the vibration-proof effect is continuous and stable.

[0170] The adjustment device also includes a protective nut 3-8, which is arranged on the adjustment bolt 3-5 outside the end of the bending energy absorber. The setting of the protective nut 3-8 is a defense mechanism to prevent the outer spring steel plate 3-6 from being disengaged from the lower end of the adjustment bolt 3-5 due to external factors. It can be understood that the protective nut 3-8 can be a nut or a processed part with an internal threaded hole.

[0171] like Figure 1 As shown, the outer wall of the hammer head 3-1 is provided with a counterweight groove 3-2. Counterweights can be added through the counterweight groove 3-2 to adjust the weight of the hammer head 3-1. Counterweights can be added as needed to provide more options for frequency adjustment.

[0172] The vibration absorbing hammer head also includes a ball joint 3-3, which is arranged on the bottom wall of the groove and is used to connect with the steel strand cluster 2. The number of the bending energy absorbers is 2, and the two bending energy absorbers are symmetrically arranged on both sides of the steel strand. The ball joint 3-3 is arranged at the center of the bottom wall of the groove.

[0173] The hammer head 3-1 is cylindrical, the groove is arranged along the axis of the hammer head 3-1, and the front and rear sides of the groove are open. The end of the hammer head 3-1 away from the groove is a spherical arc surface. In other embodiments, the hammer head 3-1 can also be a non-spherical arc surface, or a cylindrical end with a circular chamfer.

[0174] The anti-vibration hammer provided in this embodiment can adjust the bending degree of the outer spring steel plate 3-6 by adjusting the position of the adjusting nut 3-7, thereby realizing free adjustment of the frequency of the bending energy absorber, so that the anti-vibration hammer can adapt to different vibration frequencies and different environmental conditions. In addition, even if the swing direction of the hammer head 3-1 is tilted, it does not affect the bending and extension of the bending energy absorber, that is, it does not affect its anti-vibration effect.

[0175] Embodiment 7 This embodiment provides a broadband intelligent anti-vibration hammer for power transmission lines, such as Figure 3 and Figure 4 As shown, it includes a wire clamp 1, a steel strand cluster 2 and a vibration absorbing hammer 3.

Figure 1 As shown, it includes a hammer head 3-1, a groove is arranged at one end of the hammer head 3-1, the inner bottom wall of the groove is connected to the steel strand cluster 2, and a bending energy absorber is arranged between the steel strand cluster 2 and the inner wall of the groove; one end of the bending energy absorber is connected to the steel strand cluster 2 through a fixing device 3-4, and the other end of the bending energy absorber is connected to the inner wall of the groove of the hammer head 3-1 through an adjusting device; the bending degree of the bending energy absorber can be adjusted by the adjusting device.

[0176] The conductor is clamped by the wire clamp 1, and then the anti-vibration hammer is installed on the conductor. When the conductor vibrates in a breeze, the wire clamp 1 can transfer the vibration energy to the steel strand cluster 2 and the vibration absorbing hammer head 3. Energy consumption and vibration reduction are achieved through the friction, bending of the steel strand cluster 2 and the swinging, bending, friction of the vibration absorbing hammer head 3.

[0177] On the basis of the above technical solution, the steel strand cluster 2 includes an upper steel strand 2-1, and the upper steel strand 2-1 is connected to the vibration absorbing hammer 3. Specifically, the upper steel strand 2-1 is connected to the ball joint 3-3 of the vibration absorbing hammer 3, so that the vibration absorbing hammer 3 can swing around the ball joint 3-3.

[0178] In some embodiments, the number of the upper steel strands 2 - 1 is 2, and two of the upper steel strands 2 - 1 are arranged horizontally in parallel.

[0179] In addition, the steel strand cluster 2 also includes a lower layer of steel strands 2-2 and steel wires 2-3.

[0180] The lower layer of steel strands 2-2 and the two upper layer of steel strands 2-1 form an inverted triangle structure; the cross-sectional view of the steel strand cluster 2 is as follows Figure 5 shown.

[0181] The length of the lower layer steel strand 2-2 is less than the length of the upper layer steel strand 2-1. At the same time, the upper layer steel strand 2-1 and the lower layer steel strand 2-2 can be steel strands of uniform specifications, or of different specifications.

[0184] The anti-vibration hammer provided in this embodiment uses a steel strand cluster 2 to connect the wire clamp 1 and the vibration absorbing hammer head 3. The steel strand cluster 2 includes two upper steel strands 2-1 and one lower steel strand 2-2. During the vibration of the conductor, the steel strands rub against each other, and the friction energy dissipation principle is used to further enhance the vibration reduction and vibration-proof effect of the anti-vibration hammer. In addition, the steel strand cluster 2 in this embodiment increases the friction area and adjustability between the steel strands. The increase in friction area provides a stronger energy dissipation capacity. At the same time, the two ends of the lower steel strand 2-2 are free ends. Without disassembling the hammer head 3-1, it is easy to replace the lower steel strand 2-2, thereby providing greater convenience and greater operability for the frequency adjustment of the anti-vibration hammer; it is also conducive to the maintenance of the anti-vibration hammer.

After installing the anti-vibration hammer, measure the vibration angle at the hanging line again. When the re-measured vibration angle is less than the allowable vibration angle, the installation is completed. When the maximum vibration angle exceeds the allowable vibration angle, it should be measured again after adding a counterweight and keeping the anti-vibration hammer frequency unchanged, until the maximum vibration angle is less than the allowable vibration angle, the installation is completed.

[0206] In some embodiments, the vibration angle for: ; In the above formula, is the wavelength of the vibration wave, is the amplitude of the vibration wave at the measuring point, is the distance between the measuring point and the clamp entrance.

After multiple measurements, the maximum vibration angle is taken to ensure that the maximum vibration angle is less than the allowable vibration angle, thereby maximizing the vibration reduction and energy absorption effect.
