Abstract
The invention discloses an annular multi-split vibration-damping galloping preventer which comprises a closed annular tube. The external surface of the annular tube is provided with a plurality of lead clamps. The annular tube is internally provided with a vibration damping system. Furthermore antifreezing and anti-corrosion liquid is filled in the annular tube. According to the annular multi-split vibration-damping galloping preventer, integrated design of a spacer rod a multi-split galloping preventer is realized. The vibration damping system which is arranged in the closed annular tube can restrain the vertical vibration amplitude of the lead to a certain extent by means of self weight for preventing an overlarge tension load of the lead because of excessive deformation of the lead on one hand; and on the other hand, the vibration damping system can generate resonance before a power transmission lead for consuming system energy, thereby reducing torsion and vibration degrees, and prolonging service life of a lead system. Through reducing torsion amplitude of the multi-split lead in galloping, the annular multi-split vibration-damping galloping preventer has functions of effectively restraining vibration amplitude, improving a lead operation environment, and prolonging service life of the lead.

Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is done with detailed description:
As shown in Figure 1, annular of the present invention divides vibration damping anti-dance device more, comprises airtight ring pipe 7, and ring pipe 7 outer surface is provided with multiple wire clamp 1, is provided with damping shock absorption system in ring pipe 7, and is filled with antifreeze corrosion liquid 6 in ring pipe 7.Ring pipe 7 for supporting fixing cord wire clamp 1, and provides installation space for damping shock absorption system.Ring pipe 7 can adopt metal ring pipe, to ensure that the present invention has enough intensity and hardness, and can long-term stable operation.Wire clamp 1, for fixing transmission pressure, can play the conductor spacer effect of separated wires simultaneously.In the present embodiment, annularly the circumferential uniform welding of pipe 7 is at ring pipe 7 outer surface for multiple wire clamp 1, and the quantity of wire clamp 1 can be four, six or eight.
Described damping shock absorption system comprises the multiple supporting clapboards 4 be arranged in ring pipe 7, multiple supporting clapboard 4 annularly the circumferential uniform welding of pipe 7 at ring pipe 7 inner surface.Be provided with between adjacent two supporting clapboards 4 between two groups of springs, 5, two groups of springs 5 and be provided with Metal Ball 2, the two ends of spring 5 are fixedly connected with supporting clapboard 4 with Metal Ball 2 respectively.Supporting clapboard 4 can provide fixing point for spring 5, effectively can ensure that ring pipe 7 is firm not yielding simultaneously.In order to strengthen the stability of damping shock absorption system further, the present invention is also coaxially arranged with annular steel ring 3 in ring pipe 7, and spring 5 and Metal Ball 2 are set on annular steel ring 3, and Metal Ball 2 and annular steel ring 3 are slidably connected, can annularly steel ring 3 hoop motion.The antifreeze corrosion liquid 6 of filling in ring pipe 7, can either prevent spring 5 and Metal Ball 2 surface from freezing and oxide etch under extreme operating environments, can also play the effect of damping fluid simultaneously.In order to the energy reversing and produce can be absorbed when conductor galloping better, to reduce wave torsion degree and reduce vibration amplitude, it is close or consistent that spring 5 and the damping shock absorption system frequency that Metal Ball 2 forms and wiring system wave frequency, in the present embodiment, the difference that the damping shock absorption system frequency that spring 5 and Metal Ball 2 form and wiring system wave frequency be no more than that wiring system waves frequency 5%.
In the present embodiment, in ring pipe 7, annularly pipe 7 circumference is evenly provided with 3 supporting clapboards 4, and ring pipe 7 inner chamber is divided into three regions.Be provided with in each region between two groups of springs, 5, two groups of springs 5 and be provided with Metal Ball 2.Metal Ball 2 in each region and the natural frequency of the damping shock absorption system that spring 5 forms all are adjusted to close or consistent with conductor galloping frequency.Can when Galloping of Overhead Transmission Line occur, the damping shock absorption internal system in each region first produces damping vibration, and then the energy that consumption transmission pressure absorbs, and reduces to reverse amplitude.
In the present invention, complete conductor spacer and the integrated design of dividing anti-dance device from structural design more, damping shock absorption Operation system setting is in the ring pipe 7 of sealing simultaneously, effectively can reduce the impact on damping shock absorption system environments, the antifreeze corrosion liquid 6 of filling in ring pipe 7 can effectively prevent spring 5 and Metal Ball 2 surface from freezing and oxide etch under extreme operating environments, ensures steady operation of the present invention.Ring pipe 7 and the spring 5, Metal Ball 2, supporting clapboard 4, annular steel ring 3 and the antifreeze corrosion liquid 6 that arrange therein, create enough quality for improving the kinetic stability of wiring system, suppress the vibration amplitude that transmission pressure is vertical, prevent transmission pressure from wrecking because excessive deformation causes tensile loads excessive.The Metal Ball 2 be set on annular steel ring 3 can be rolled in the ring pipe 7 being full of antifreeze corrosion liquid 6, produces the consumed energy that rubs when Metal Ball 2 is rolled and between antifreeze corrosion liquid 6; When Metal Ball 2 is rolled, spring 5 is compressed, and spring 5 is compressed rear energy by supporting clapboard 4 is passed to ring pipe 7, damping shock absorption system in the present invention can be made prior to transmission pressure generation covibration, consumption systems energy, thus reduce to reverse and extent of vibration, extension lead system useful life.
