Power transmission line anti-play damping device

Abstract

The invention relates to the technical field of cable damping, and discloses a power transmission line anti-play damping device which comprises an outer shell and a ball core. A spherical cavity is formed in the outer shell, and the spherical core is sleeved with the spherical cavity. A notch is formed in the right side of the spherical cavity, and vent holes are formed in the four corners of thespherical cavity in a penetrating mode and communicated with the outside. An electric wire channel is formed in the ball core; an electric wire through hole is formed in the left side of the sphericalcavity; a first sliding groove is formed in the inner wall of the spherical cavity, and a second sliding groove is formed in the outer surface of the spherical core; a first guide rod is arranged onthe inner wall of the spherical cavity, a second guide rod is arranged on the outer surface of the spherical core, and a first sphere and a second sphere are arranged on the first guide rod and the second guide rod respectively; and 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 problemsthat in the prior art, the protection effect of a shock absorber for a cable is not obvious enough, the protection effect cannot be achieved for a long time, and the shock absorber is prone to losingefficacy are solved.

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...

AI Technical Summary

Problems solved by technology

[0004] The invention provides an anti-movement damping device for transmission lines, which has the advantages of good performance, simple structure, stability and reliability, and is not easy to fail, and solves the problem that the shock absorbers used for cables in the prior art have insufficient protection Obviously, it cannot protect for a long time, and the shock absorber is easy to fail
