Description

Technical Field

[0001] This invention relates to the field of vibration damping hammer technology, specifically to a vibration damping hammer with a liquid damping device. Background Technology

[0002] When power transmission lines are subjected to wind, they vibrate. Repeated vibrations can cause fatigue damage to the transmission lines. Therefore, it is necessary to install vibration dampers on the transmission lines to reduce vibrations caused by wind. Vibration dampers are located between two poles or towers. Under the action of wind, the transmission lines will sway relatively strongly. If they are not effectively restricted, the conductors will be prone to fatigue damage, conductor strand breakage, and affect the normal operation of the power line. When the swaying is severe, it may even damage the insulators and hardware connected at both ends of the conductor, resulting in losses.

[0003] When a conductor vibrates, the relative motion of the vibration dampers suspended on the conductor attracts the conductor's vibrational energy, thereby reducing and eliminating the vibration. However, due to limitations in the damper's installation location and mass distribution, vibration dampers can only eliminate vibrations of specific frequencies. Their vibration reduction capability is poor for other frequencies. Summary of the Invention

[0004] The purpose of this invention is to provide a vibration damping hammer with a liquid damping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A vibration damping hammer with a liquid damping device includes a clamp device installed on an optical cable and a damping mechanism fixed to the lower end of the clamp device. The clamp device includes an upper clamp connected to the optical cable and a lower clamp located below the upper clamp, and the upper and lower clamps are connected by a buffer mechanism. The damping mechanism includes a horizontal bar fixed to the lower clamp, with a large hammer installed at one end of the horizontal bar and a small hammer installed at the other end. A metal ball is suspended below both the large and small hammers. The metal ball is a hollow sphere with an open top, and a sealing mechanism is provided at the opening of the sphere. The sphere contains damping fluid. The sealing mechanism includes a sealing seat installed at the opening of the sphere and a sealing locking mechanism that rotates with the sealing seat to achieve a sealing function.

[0007] As a further improvement to the above technical solution:

[0008] The sealing seat is a cylindrical structure with an open top. The bottom of the sealing seat is provided with a slot. The sealing locking mechanism includes a sealing plug of a size adapted to the sealing seat, a locking block located on the lower side of the sealing seat, and a connecting piece for connecting the locking block and the sealing plug. The shape formed by the locking block and the connecting piece is adapted to the size of the slot. The sealing plug is provided with a horizontal movable groove. A locking piece for locking the sealing seat and the sealing locking mechanism is installed in the movable groove.

[0009] The locking component includes a locking spring horizontally disposed within the movable groove. A locking rod is fixed to each end of the locking spring. The other end of the locking rod extends through the movable groove to the outside of the sealing plug. The cylindrical structure of the sealing seat is provided with a positioning hole that mates with the locking rod. The locking rod is also provided with a push block that extends vertically upward along its side. The sealing plug is provided with a sliding groove that mates with the push block. Under the action of the locking spring, the locking rod slides left and right within the movable groove through the push block, thereby locking the sealing seat and the sealing locking mechanism.

[0010] The buffer mechanism includes an upper connecting block connected to the upper clamp and a lower connecting block connected to the lower clamp. The upper connecting block and the lower connecting block are connected by a rigid wall plate. Rubber columns are symmetrically arranged on both sides of the rigid wall plate. The two ends of the rubber columns are fixedly connected to the upper connecting block and the lower connecting block, respectively. A thrust spring is sleeved on the outside of the rubber column. A circular groove is vertically opened inside the rubber column. A buffer component is installed in the circular groove.

[0011] The buffer component includes a limiting rod installed in the circular groove. Each end of the limiting rod is provided with a buffer spring, and the limiting rod is positioned in the middle of the circular groove by the buffer springs at both ends.

[0012] The upper clamp is U-shaped, and a protective pad is provided on the inner side of the upper clamp that connects to the optical cable. The lower clamp is a horizontally set cylinder, and a mounting hole for installing the crossbar is opened on the cylindrical lower clamp.

[0013] As can be seen from the above technical solution, the anti-vibration hammer with liquid damping device of the present invention prevents the back spring from shaking back and forth by installing a buffer mechanism on the wire clamp device, so that the upper and lower wire clamps can quickly return to a stable state. By filling the metal ball with ethylene glycol antifreeze, when the anti-vibration hammer vibrates, the large and small hammers at both ends of the crossbar vibrate, which in turn drives the metal ball to vibrate. When the metal ball vibrates, the center of gravity changes, that is, the metal ball drives the ethylene glycol antifreeze to vibrate. The sloshing of the liquid generates a wave force, which can also dissipate energy from the vibration of the wire, thereby reducing the vibration. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1 , 2 As shown, the anti-vibration hammer with liquid damping device in this embodiment includes a clamp device 2 installed on the optical cable 1 and a damping mechanism 3 fixed at the lower end of the clamp device 2.

[0023] like Figure 3 , 4As shown, the clamp device 2 includes an upper clamp 21 connected to the optical cable 1 and a lower clamp 22 located below the upper clamp 21. The upper clamp 21 and the lower clamp 22 are connected by a buffer mechanism. The buffer mechanism can prevent the back spring 27 from bouncing back and forth.

[0024] The buffer mechanism includes an upper connecting block 23 connected to the upper clamp 21 and a lower connecting block 24 connected to the lower clamp 22. The upper connecting block 23 and the lower connecting block 24 are connected by a rigid wall plate 25. Rubber columns 26 are symmetrically arranged on both sides of the rigid wall plate 25. The two ends of the rubber columns 26 are fixedly connected to the upper connecting block 23 and the lower connecting block 24, respectively. A thrust spring 27 is sleeved on the outside of the rubber column 26. A circular groove 28 is vertically opened inside the rubber column 26, and a buffer element 29 is installed in the circular groove 28. In this embodiment, the thrust spring 27 meets certain elastic stiffness requirements. The thrust spring 27 can withstand the weight of the hammer 32, the hammer 33, and the metal ball 34, ensuring the normal use of the device.

[0025] The buffer component 29 includes a limiting rod 291 installed in the circular slide groove 28. A buffer spring 292 is provided at each end of the limiting rod 291. The limiting rod 291 is positioned in the middle of the circular slide groove 28 by the buffer springs 292 at both ends. When the push spring 27 is compressed, the upper wire clamp 21 and the lower wire clamp 22 simultaneously squeeze the rubber column 26 and the buffer spring 292 in the buffer mechanism. The rebound causes the limiting rod 291 to slide along the circular slide groove 28. At the same time, the rubber column 26 limits the movement distance of the limiting rod 291. The rubber column 26 cooperates with the limiting rod 291 to prevent the push spring 27 from shaking back and forth, so that the upper wire clamp 21 and the lower wire clamp 22 can quickly return to a stable state.

[0026] In this embodiment, the upper clamp 21 is U-shaped, and the inner side of the upper clamp 21 connected to the optical cable 1 is provided with a protective pad 4. The lower clamp 22 is a horizontally set cylinder, and the cylindrical lower clamp 22 has a horizontally opened mounting hole 221 for mounting the crossbar 31.

[0027] like Figure 2 , 5As shown in Figure 6, the damping mechanism 3 includes a horizontal bar 31 fixed to the lower clamp 22. A large hammer 32 is installed at one end of the horizontal bar 31, and a small hammer 33 is installed at the other end. A metal ball 34 is suspended below both the large hammer 32 and the small hammer 33. The metal ball 34 is a hollow sphere with an open top. The opening of the sphere is equipped with a sealing mechanism, and the inside of the sphere is filled with damping fluid. The sphere is connected to the large hammer 32 and the small hammer 33 by ropes. In this embodiment, the damping fluid is ethylene glycol-based antifreeze. When the damping hammer vibrates, the large hammer 32 and the small hammer 33 at both ends of the horizontal bar 31 vibrate, which in turn drives the metal ball 34 to vibrate. When the metal ball 34 vibrates, the center of gravity changes, that is, the metal ball 34 drives the ethylene glycol-based antifreeze to vibrate. The sloshing of the liquid generates a wave force, which can also dissipate energy from the vibration of the conductor, thereby reducing the vibration.

[0028] like Figure 5 , 6 As shown, the sealing mechanism includes a sealing seat 35 installed at the opening of the sphere and a sealing locking mechanism 36 that rotates with the sealing seat 35 to achieve the sealing function. The sealing seat 35 is a cylindrical structure with an open top. A groove 351 is provided at the bottom of the sealing seat 35. The sealing locking mechanism 36 includes a sealing plug 361 whose size is adapted to the sealing seat 35, a locking block 362 located on the lower side of the sealing seat 35, and a connecting member 363 for connecting the locking block 362 and the sealing plug 361. The shape formed by the locking block 362 and the connecting member 363 is adapted to the size of the groove 351. In this embodiment, the groove 351 adopts a butterfly shape, which is composed of a round hole in the middle and two elongated holes on both sides of the round hole. The two elongated holes communicate with the round hole. This shape facilitates the rotational engagement of the sealing seat 35 and the sealing locking mechanism 36. A movable groove 364 is horizontally provided in the sealing plug 361. A locking member for locking the sealing seat 35 and the sealing locking mechanism 36 is installed in the movable groove 364. A sealing ring is installed between the sealing seat 35 and the sealing plug 361, thereby sealing the sealing seat 35 and the metal ball 34.

[0029] The locking component includes a locking spring 365 horizontally disposed in the movable groove 364. A locking rod 366 is fixed to each end of the locking spring 365. The other end of the locking rod 366 extends through the movable groove 364 to the outside of the sealing plug 361. The cylindrical structure of the sealing seat 35 is provided with a positioning hole 352 that cooperates with the locking rod 366. The locking rod 366 is also provided with a push block 367 that extends vertically upward along its side. The sealing plug 361 is provided with a sliding groove 368 that cooperates with the push block 367. Under the action of the locking spring 365, the locking rod 366 slides left and right in the movable groove 364 through the push block 367, thereby locking the sealing seat 35 and the sealing locking mechanism 36.

[0030] Working principle: For different regions, based on local meteorological data, metal balls 34 of varying sizes can be selected to adjust the liquid volume inside the balls and achieve the best shock absorption effect. When it is necessary to change the liquid volume inside the metal ball 34, first push the two push blocks 367 at the upper end of the sealing seat 35 inwards, causing the locking rod 366 to move out of the movable groove 364. Then rotate the sealing seat 35 ninety degrees, causing the locking block 362 to rotate directly below the sliding groove 368. At this point, the sealing seat 35 can be removed from the upper end of the metal ball 34, thus allowing adjustment of the volume of the ethylene glycol-based antifreeze inside the metal ball 34. The volume is increased or decreased to meet the required requirements. After completion, the locking block 362 at the lower end of the sealing seat 35 is inserted downward along the slide groove 368, and the connecting piece 363 is inserted downward along the locking groove 351. At the same time, the push block 367 is pushed inward. When the sealing seat 35 is fully engaged with the upper end of the metal ball 34, the push block 367 is released, and the sealing seat 35 is rotated ninety degrees. Under the action of the locking spring 365, the locking rod 366 is engaged with the movable groove 364, and the locking block 362 is engaged with the metal ball 34, thereby sealing the connection between the sealing seat 35 and the metal ball 34.

[0031] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements to the technical solutions of the present invention made by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
