Description

Technical Field

[0001] The invention belongs to the technical field of electric power construction, and in particular relates to an anti-falling broadband vibration-reducing and energy-consuming anti-vibration hammer. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Transmission lines erected at high altitudes are easily affected by air flow and produce mechanical vibration. The anti-vibration hammer is designed to reduce the vibration of the wire caused by wind. The pole position of the high-voltage overhead line is high and the span is large. When the wire is vibrated by wind, the working conditions at the wire hanging point are the most unfavorable. Due to multiple vibrations, the wire will suffer fatigue damage due to periodic bending. When the span of the overhead line is greater than 120 meters, an anti-vibration hammer is generally used for vibration prevention.

[0004] Traditional wire clamp-type vibration damping hammers are usually fastened with bolts to fix the entire vibration damping hammer on the cable. However, when the cable is clamped for a long time, it will become thinner, making it easy for the vibration damping hammer to slide on the cable. When the cable breaks due to the external environment, the vibration damping hammer will shake off the cable and be lost, causing losses to people. On the other hand, most of the existing devices are passive vibration damping devices, which have limited ability to restrain the vibration of the wire, cannot achieve automatic adjustment, and lack autonomy. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an anti-falling broadband vibration-reducing and energy-consuming anti-vibration hammer, which can avoid the breeze vibration phenomenon of the transmission line, solve the problem of the anti-vibration hammer sliding and falling on the transmission line, realize semi-autonomous control of the anti-vibration hammer, and ensure the safe operation of the transmission line under the action of long-term breeze.

For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be an internal connection between two elements, or an interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0039] As introduced in the background technology, there are currently few devices for simultaneously suppressing the breeze vibration of power transmission lines and reducing the noise caused by power transmission lines, and most of them are passive vibration reduction devices, which have limited ability to restrain the vibration of the wires, cannot achieve automatic adjustment, and lack autonomy. In order to solve the above technical problems, the present invention proposes an anti-drop broadband vibration reduction energy-consuming anti-vibration hammer.

[0040] The present invention provides a wide-band vibration-damping and energy-dissipating anti-vibration hammer, such as Figure 1 As shown, it includes a clamping device 1 and a vibration reduction and energy dissipation device, the clamping device 1 includes an outer box body 4, the outer box body 4 includes an upper box body and a lower box body, the two are detachably connected, a vertical drive device and a first clamping plate 6 are arranged on the upper box body, and a cavity 13, a second clamping plate 10, a preload spring 9, a light spring 31, a mass block 14, a rectifier 12, a displacement sensor 11, a piezoelectric inductor unit 32, a permanent magnet 7, an electromagnet 8, a first controller 37, etc. are arranged on the lower box body;

[0041] The first clamping plate 6 and the second clamping plate 10 are both arc-shaped and have the same size; a wire clamping hole 38 is formed between the first clamping plate 6 and the second clamping plate 10, and the wire can pass through the wire clamping hole 38 and connect with the clamping device 1 (according to Figure 2The wire is guided to pass horizontally through the wire clamping hole 38). A rubber layer is distributed in the area where the lower part of the first clamping plate 6 and the upper part of the second clamping plate 10 contact the wire to prevent damage to the wire during the clamping process.

[0042] The above-mentioned first clamping plate 6 can move up and down. The first clamping plate 6 is manually driven to move up and down by a vertical driving device. The vertical driving device includes two sets. Each set of sliding devices 2 includes a sliding rod 5 and a sliding sleeve 3. The sliding sleeve 3 is threadedly connected to the sliding rod 5. By rotating the sliding sleeve 3, the sliding rod 5 can be adjusted up and down, thereby adjusting the first clamping plate 6 to move up and down; the sliding sleeves of the two sets of vertical driving devices are installed on the top of the outer box body through the sliding device 2; the sliding rod 5 is fixed to the upper surface of the first clamping plate 6 and cannot move further.

[0043] The second clamping plate 10 can move up and down, which is automatically controlled by another set of devices. Specifically, an electromagnet 8 is provided on the second clamping plate 10, and a preload spring 9 is provided between the second clamping plate 10 and the cavity 13. When the magnetism of the electromagnet 8 on the second clamping plate 10 changes, the change in magnetic force causes the preload spring 9 to stretch and compress, driving the second clamping plate 10 to move up and down. In the initial state, the spring on the second clamping plate 10 is the preload spring 9, and negative stiffness is formed in the initial state.

[0044] At the same time, a cavity 13 is also provided in the lower box body, and a light spring 31 is provided in the cavity. The two ends of the light spring 31 are connected to the mass block 14, and a piezoelectric inductor unit 32 is provided on the side wall of the cavity 13. When the mass block 14 hits the piezoelectric inductor unit 32 under the action of external force, a current is generated, and the generated current is stored in the rectifier 12, so the piezoelectric inductor unit 32 is connected to the rectifier 12;

[0045] Further, the vibration reduction and energy dissipation device includes a first transmission shaft 40, a second rotating shaft 39, a vertical movable cylinder 29, a first horizontal movable cylinder 24, a second horizontal movable cylinder 43, a damping cylinder 30, a connecting spring 28, a connecting block 15, a connecting cylinder 41, a stopper 27 and a flying disc 26;

[0046] The top of the first transmission shaft 40 is vertically fixed to the bottom of the outer box body 4 through the connecting block 15. The first transmission shaft 40 passes through the connecting cylinder 41, the vertical movable cylinder 29 and is connected to the damping cylinder 30. The first transmission shaft 40 and the connecting cylinder 41 are fixed together, and the first transmission shaft 40 and the vertical movable cylinder 29 are slidably connected. The bottom of the first transmission shaft 40 is inserted into the damping cylinder 30 and is threadedly connected to the damping cylinder 30.

[0047] A threaded screw 25 is connected to one end of the connecting cylinder 41, and the other end is connected to the second rotating shaft 39; the threaded screw 25 cooperates with the first horizontal movable cylinder 24, and the second rotating shaft 39 cooperates with the second horizontal movable cylinder 43; and the first horizontal movable cylinder 24 is connected to one side of the vertical movable cylinder 29 through a spring 28, and the second horizontal movable cylinder 43 is connected to the other side of the vertical movable cylinder 29 through another spring;

[0048] In the initial state, the vertical movable cylinder 29, the first horizontal movable cylinder 24 and the second horizontal movable cylinder 43 remain stationary under the action of the spring; when the breeze vibrates, the vertical movable cylinder 29 moves up and down to squeeze and stretch the connecting spring 28, driving the first horizontal movable cylinder 24 and the second horizontal movable cylinder 43 to move left and right. The left and right movements of the first horizontal movable cylinder 24 and the second horizontal movable cylinder 43 in turn limit the vertical movable cylinder 29 from moving up and down through the connecting spring 28.

[0049] The vertical movable cylinder 29 can move up and down on the first transmission shaft 40 , the first horizontal movable cylinder 24 can move left and right on the threaded screw 25 , and the second horizontal movable cylinder 43 can move left and right on the second rotating shaft 39 .

[0050] Furthermore, limiters 27 are provided at both ends of the threaded sections of the first transmission shaft 40, the threaded screw 25, and the second rotating shaft 39 to limit further movement of the vertical movable cylinder 29, the first horizontal movable cylinder 24, and the second horizontal movable cylinder 43 to prevent damage to the threaded screw.

[0051] Furthermore, the vertical movable cylinder 29 has two inner cylinders 18, the inner cylinder 18 and the vertical movable cylinder 29 are connected by energy-absorbing springs 19 arranged up and down, the two inner cylinders 18 are connected by a first transmission shaft 40, the first transmission shaft 40 is sleeved on the first transmission shaft 40, and there are multiple mass balls 20 in the two inner cylinders 18. When the vertical movable cylinder 29 moves up and down, the inner cylinder 18 moves up and down under the action of the mass balls 20, compressing or stretching the energy-absorbing springs 19, and driving the multiple mass balls 20 in the inner cylinder 18 to collide with each other.

[0052] Furthermore, the damping cylinder 30 contains magnetorheological fluid, and the first transmission shaft 40 is inserted into the bottom of the damping cylinder 30; the first transmission shaft 40 is inserted into the magnetorheological fluid part and the energized coil 22 is wrapped around it, and is connected to a plurality of fan blades 23, on which there is a damping net. Since the first transmission shaft 40 and the damping cylinder are threadedly connected, when the first transmission shaft 40 makes a linear motion, the damping cylinder 30 can rotate, thereby achieving the effect of the damping net cutting the magnetorheological fluid to increase the energy consumption; there is a controller on the first damping cylinder 30 to control the current in the energized coil 22.

[0053] like Figure 4As shown, magnetic sheets with different magnetic properties are arranged at intervals inside the first horizontal movable cylinder 24 and the second horizontal movable cylinder 43, and a closed magnetic field is generated between the magnets with different magnetic properties. The strip conductor plate 17 is arranged in a ring inside the spiral area of ​​the threaded screw 25 and the second rotating shaft 39. When the threaded screw 25 and the second rotating shaft 39 rotate, the internal strip conductor plate 17 cuts the magnetic field.

[0054] like Figure 5 As shown, the flying disc 26 is provided with a fan-shaped chassis 44, an annular magnet 35, a small iron ball 36, a compression spring 33 and a buffer rubber 34, and the small iron ball 36 is inside the fan-shaped chassis 44. The inside of the flying disc 26 is divided into multiple areas, each of which is provided with a fan-shaped chassis 44, and a ring-shaped annular magnet 35 is provided at the center of the multiple fan-shaped chassis 44, and each fan-shaped chassis 44 is connected to the inner wall of the flying disc 26 through a compression spring 33, and the small iron ball 36 in each fan-shaped chassis 44 has different masses, which widens the frequency distribution range of vibration reduction; a buffer rubber 34 is provided on the outer ring of the compression spring 33; in the initial state, the fan-shaped chassis and the small iron ball 36 are distributed around the center of the annular magnet 35 and remain stationary under the action of magnetic force.

[0055] The fan-shaped chassis can move along the compression spring 33 inside the flying disc 26, and the small iron ball 36 can move inside the fan-shaped chassis. The movement of the fan-shaped chassis and the small iron ball 36 can achieve a significant change in the mass of the flying disc 26. The flying disc 26 is detachably connected to the corresponding threaded screw 25 and the second rotating shaft 39, which is convenient for updating at any time, or selecting a flying disc 26 with different mass distribution according to different breeze vibrations.

[0056] Furthermore, the annular magnet 35 is an electromagnet, and the third controller 42 can adjust the magnitude and direction of the current on the annular magnet.

[0057] The damping cylinder 30, the first horizontal movable cylinder 24 and the flying disc 26 are all provided with insulating layers to prevent mutual influence with the surrounding electric current and magnetic field.

[0058] like Figure 6 As shown, the rectifier 12, the first controller 37, the second controller 21, the third controller 42, the electromagnet 8, the energized coil 22 and the annular magnet 35 form a closed loop, the first controller 37 controls the magnitude and direction of the current in the electromagnet 8, the second controller 21 controls the magnitude of the current in the energized coil 22, and the third controller 42 controls the magnitude and direction of the current in the annular magnet 35.

[0059] The specific working process of the present invention is as follows:

[0060] First, when installing the anti-falling wide-band vibration-damping and energy-absorbing anti-vibration hammer, pass the transmission line through the wire clamping hole 38 so that the lower surface of the transmission line contacts the rubber layer on the upper surface of the second clamping plate 10 on the lower box body. Then install the upper box body, connect the upper box body and the lower box body, rotate the sliding sleeve 3, so that the first clamping plate 6 clamps the transmission line; until the rubber layer on the lower surface of the first clamping plate 6 is in close contact with the upper surface of the transmission line, clamping the sliding device.

[0061] When the transmission line swings in the breeze, the mass block 14 inside the cavity 13 moves along the direction of the light spring 31, collides with the piezoelectric inductor unit 32, and the generated current is stored in the rectifier 12. During long-term clamping, the transmission line shortens or shakes, and the distance between the first clamping plate 6 and the second clamping plate 10 changes. The displacement sensor 11 senses and transmits the signal to the first controller 37. The first controller 37 changes the magnitude and direction of the current in the electromagnet 8, changes the magnitude of the magnetic force, controls the second clamping plate 10 to move up and down, and prevents the clamping device 1 from falling off the transmission line.

[0062] When the vibration of the transmission line is transmitted downward, the first transmission shaft 40 is driven to move downward synchronously, and the vertical movable cylinder 29 moves relative to the first transmission shaft 40 under the action of inertia. The inner cylinder 18 of the vertical movable cylinder 29 moves up and down under the action of inertia to compress and stretch the energy-absorbing spring 19, thereby achieving the effect of energy dissipation. At the same time, the vibration of the inner cylinder 18 causes the mass balls 20 inside to collide with each other, further consuming energy.

[0063] Since the first transmission shaft 40 is inserted into the bottom of the damping cylinder 30, the damping cylinder 30 drives the surrounding damping net 23 to rotate and cut the magnetorheological fluid to consume energy during its rotation. The rectifier 12 provides current to the energized coil 22 around the first transmission shaft 40, and the first controller 37 controls the magnitude of the current in the energized coil 22 to change the magnetic field, thereby actively affecting the damping and viscosity of the magnetorheological fluid to achieve a better vibration reduction and energy consumption effect.

[0064] The connecting spring 28 is stretched and compressed during the vertical movement of the vertical movable cylinder 29, thereby driving the first horizontal movable cylinder 24 to move left and right along the second rotating shaft 39. Since the first horizontal movable cylinder 24 moves along the threaded screw 25, the second rotating shaft 39 is driven to rotate. Bar magnets 16 with different magnetic properties are arranged at intervals inside the first horizontal movable cylinder 24 to generate a closed magnetic field. When the second rotating shaft 39 rotates, the internal strip conductor plate 17 cuts the magnetic field, and eddy currents are formed inside the strip conductor plate 17, and the generated heat energy is dissipated from the air.

[0065] In the initial state, the fan-shaped chassis and the small iron ball 36 remain stationary around the annular magnet 35 under the action of magnetic force. When the second rotating shaft 39 rotates, it drives the flying disc 26 to rotate. When the rotating speed of the flying disc 26 is low, the centrifugal force received by the movable fan-shaped chassis is small, and the small iron ball 36 and the fan-shaped chassis are not far away from the annular magnet 35. When the rotating speed of the flying disc 26 increases, the centrifugal force received by the small iron ball 36 increases, and it begins to move away from the annular magnet 35 to move around and collide with each other to consume energy, and the fan-shaped chassis is still distributed around the annular magnet 35. When the speed of the flying disc 26 further increases, the small iron ball 36 is away from the center of the annular magnet 35, and the fan-shaped chassis moves along the compression spring 33 and the buffer rubber 34 to achieve the effect of vibration reduction and energy consumption. After the speed of the flying disc 26 is reduced, the fan-shaped chassis and the small iron ball 36 inside the flying disc 26 recover the initial distribution state. During the movement of the small iron ball 36 and the fan-shaped chassis, the magnetic force is controlled by the annular magnet 35 to change the mass distribution inside the flying disc 26, so that the anti-vibration hammer can adapt to vibration reduction in different frequency ranges.

[0066] The present invention has the dual functions of preventing falling off and reducing vibration, which can prevent the anti-vibration hammer from sliding off on the transmission line, and at the same time suppress the phenomenon of breeze vibration on the transmission line. A variety of energy dissipation methods are adopted, including spring energy dissipation, collision energy dissipation, magnetorheological fluid energy dissipation, electromagnetic induction energy dissipation and other methods, to achieve semi-autonomous control of the vibration reduction energy dissipation device, and by making the apparent mass of the flying disc variable, the range of vibration reduction frequency is widened. At the same time, the present invention has a simple structure, is easy to install and replace, and has good application prospects.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
