Anti-movement shock absorbing device for transmission line

Abstract

The invention relates to the technical field of cable damping, and discloses an anti-movement damping device for transmission lines, which includes an outer shell and a ball core; a spherical cavity is arranged in the outer shell, and the ball core is sleeved in the center cavity; the spherical The right side of the cavity is provided with a notch, and the four corners of the spherical cavity are provided with ventilation holes, which communicate with the outside world; the ball core is provided with a wire channel, and the left side of the spherical cavity is provided with a wire through hole; the inner wall of the spherical cavity is provided with There is a first sliding groove, the outer surface of the ball core is provided with a second sliding groove; the inner wall of the spherical cavity is provided with a first guide rod, the outer surface of the ball core is provided with a second guide rod, the first guide rod and the second guide rod A first sphere and a second sphere are respectively provided; the first guide rod and the second guide rod are respectively connected with a first magnet and a second magnet with the same magnetism at opposite ends; The protective effect is not significant enough, it cannot play a protective role for a long time, and the shock absorber is easy to fail.

Description

technical field [0001] The invention relates to the technical field of cable damping, in particular to an anti-movement damping device for power transmission lines. Background technique [0002] The power transmission line is erected in the field, and it is often affected by the wind to cause shaking and vibration. In some cases, even if it is not a windy day, the vibration will become more and more intense due to resonance, and the amplitude will become larger and larger, eventually causing The transmission line is disconnected, the equipment is damaged, and the normal power transmission is affected. [0003] The invention whose publication number is CN110474275A in the prior art discloses a transmission line cable shock absorber and its installation method. The shock absorber includes a hollow sphere and a solid sphere inside the hollow sphere. A notch is arranged on the surface of the hollow sphere. The hollow sphere, A cable connection ring is arranged on the outer surf...
