Abstract
The utility model discloses the windproof dancing device of a kind of power transmission line, comprise two donut structures, described two donuts are fixedly connected with by linking arm, wherein inner ring is hinged with power transmission cable support arm, outer shroud is made up of the ring segment of two formed objects, described support arm passes between two ring segments of outer shroud, the both sides of described support arm are provided with arc damping fin, described damping fin is arranged on described outer shroud, and described annulus, described linking arm, described support arm and described damping fin are plastic part.Power transmission line, when swinging, acts on support arm by damping fin, carries out damping effectively and suppresses, prevent wind from waving to it.The utility model is easy, practical, cost is low.
Description
Technical field
The utility model relates to electric power transmission line anti-dance technical field, particularly relates to the windproof dancing device of a kind of power transmission line.
Background technology
Power transmission line wind dance is one of principal element threatening transmission line security of operation, and the lighter can cause line flashover, tripping operation, and gold utensil can occur severe one, insulator damages, lead () line breaks stock, broken string, steel tower bolt gets loose, and even tower, brings serious harm to the safe operation of electric power system.
The utility model patent that publication number is CN 202917920 U discloses and a kind ofly provides the damp type anti-dance device of high-efficiency vibration damping for overhead transmission line, it connects support arm on two frameworks of multiple fission conductor conductor spacer, is connected and fixed the metal cylinder of a built-in damping-article through support arm.It is mated with multiple fission conductor conductor spacer and uses.Because metal cylinder and damping-article are added together enough quality, the kinetic stability of wiring system can be improved, play the effect of two parallel wielded-proof device, simultaneously Metal Ball can in metal cylinder internal damping liquid Free-rolling, Metal Ball roll time and damping fluid produce the consumed energy that rubs, and Compress Spring, absorb energy after spring-compressed and can produce collision impact with the sealing baffle in metal cylinder or two ends spring and change wiring system frequency, reliably suppress waving of overhead transmission line conductor.Its weak point is: Metal Ball and damping fluid add the weight of anti-dance device significantly, larger burden is caused to transmission line and electric force pole tower, and it is not routine in repair and maintenance, there is the potential safety hazard that damping fluid leaks, after damping fluid leaks, easily cause gathering of dust, run into the generation that rainwater easily causes the situations such as phase fault.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides that a kind of structure is simple, quality is light, easy to maintenance, and effectively suppress the windproof dancing device of power transmission line of transmission line galloping situation.
The technical scheme adopted for realizing the purpose of this utility model is: the windproof dancing device of a kind of power transmission line, comprise two donut structures, described two donuts are fixedly connected with by linking arm, wherein inner ring is hinged with power transmission cable support arm, outer shroud is made up of the ring segment of two formed objects, described support arm passes between two ring segments of outer shroud, the both sides of described support arm are provided with arc damping fin, described damping fin is arranged on described outer shroud, and described annulus, described linking arm, described support arm and described damping fin are plastic part.
Described inner ring also two formed objects ring segment composition, described support arm is rotationally connected by two ring segments of rotating shaft and described inner ring.
Described damping fin is arranged on outer shroud by bearing pin.
The windproof dancing device of power transmission line of the application, by adopting two interconnective donut structures, inner ring is hinged with power transmission cable support arm, and support arm damping fin is set on outer shroud, thus have effectively achieved power transmission line when swinging, damping inhibitory action is effectively carried out to it, thus realize the windproof dance function of transmission line, simultaneously, donut, linking arm, support arm and damping fin all adopt plastic part, significantly reduce the weight of device, avoid causing overcharge to transmission line and electric force pole tower, minimizing binding post is the potential safety hazard such as off-line or fracture because circuit is overweight, there is employing damping fluid, existing damping fluid in the art can be effectively avoided to leak the phase fault caused, the security incident generation that suspension etc. are unnecessary.The utility model is easy, practical, cost is low, and should be widely promoted application.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side-looking structural representation of the donut of the utility model embodiment two.
Embodiment
Embodiment one
As shown in Figure 1: the windproof dancing device of a kind of power transmission line, comprise two donut structures, described two donuts are fixedly connected with by linking arm 8, wherein inner ring 1 is monolithic ring and is hinged with power transmission cable support arm 5, outer shroud 2 is made up of the ring segment of two formed objects, described support arm 5 one end is connected by rotating shaft 7 with described inner ring 1, the other end passes between two ring segments of outer shroud 2, and be provided with power transmission cable fixture 6, described fixture 6 is cable clamp, the both sides of described support arm 5 are provided with arc damping fin 4, described damping fin 4 is arranged on outer shroud 2 by bearing pin 3, described inner ring 1, outer shroud 2, described linking arm 8, described support arm 5 and described damping fin 4 are plastic part.
Embodiment two
As shown in Figure 2: the difference part of the present embodiment and embodiment one is: described inner ring 1 and outer shroud 2 form by the ring segment of two formed objects, and connect as one structure by adding cylinder 9 between two of described inner ring ring segments.
Windproof dance inhibiting mechanism of the present utility model is, when power transmission line swings, support arm 5 with the rotating shaft 7 in inner ring 1 for the center of circle rotates, meanwhile, damping fin 4 on outer shroud 2 is to absorption support arm 5 revolving force, thus make the pendulum of power transmission line a less degree of convergence, avoid that pendulum is excessive causes security threat to transmission line and shaft tower.
