Description
Technical field
The utility model relates to a kind of wire vibration abatement, particularly relates to a kind of wire vibration abatement be suspended on overhead transmission line.
Background technology
High voltage overhead lines line conductor often hangs a hand hammer, and this hand hammer is stockbridge damper, and stockbridge damper is established to reduce conductor vibration.Current stockbridge damper is made up of wire clamp clamping plate, steel strand wire and cast iron tup, is arranged on wire.When overhead transmission line produces vibration, stockbridge damper is up-down vibration thereupon, due to the inertia effect of tup, steel strand wire is constantly bent up and down, thus consumed energy, play shockproof effect.Existing stockbridge damper is of a great variety, and in order to increase the service life, those skilled in the art have carried out many improvement.But still it is not all roses.Because overhead transmission line is except aeolian vibration, under the bad weathers such as some rain, snow and strong wind, the External Force Acting suffered by the tup of stockbridge damper strengthens, and often occurs disengaging situation between tup and steel strand wire, the useful life of stockbridge damper is shortened, safeguards that changing operation increases.Simultaneously because tup is subject to External Force Acting, significantly waving of wire can be strengthened, reduce the useful life of wire.And existing stockbridge damper need further raising preventing the effect in aeolian vibration.
Summary of the invention
The utility model is exactly to solve the problems of the technologies described above, and provide a kind of wire vibration abatement, this further improves the effect preventing wire aeolian vibration, long service life, also there is the effect reducing wire and significantly wave simultaneously, effectively extend the useful life of transmission pressure, shockproof effect is remarkable.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
Wire vibration abatement, its structure is as follows: the wire clamp clamping plate of stockbridge damper are connected with power transmission clamping plate by weakening spring, wire clamp clamping plate and power transmission clamping plate are arranged on wire, stockbridge damper comprises wire clamp clamping plate, steel strand wire and tup, wherein one end of steel strand wire is arranged in tup, and the other end and the wire clamp clamping plate of steel strand wire are fastenedly connected, and the structure of tup is as follows: be positioned at the left wheel hub of both sides and right wheel hub, be provided with wheel shaft between left wheel hub and right wheel hub, wheel shaft is set with rotatable impeller.
The equidistant setting of blade on above-mentioned impeller, the outer rim of blade exceeds left wheel hub and right wheel hub outer rim 1.5-2 centimetre the best.
The structure of above-mentioned power transmission clamping plate is identical with the structure of wire clamp clamping plate.
Owing to adopting technique scheme, the utility model tool is had the following advantages and effect:
The utility model, being connected with power transmission clamping plate by weakening spring by the wire clamp clamping plate of stockbridge damper, can absorb the vibrational energy of a part of wire, plays the effect improving shockproof effect further.What the integral structure of tup was innovated by the utility model makes wheel hub, wheel shaft type structure into, and on wheel shaft sheathed impeller, like this under the prerequisite not changing tup overall weight, time on the External Force Acting to tup such as wind, rain, snow, hail of external force, impeller can lay down a part of external force, effectively reduces significantly waving of wire.Due to the setting of impeller and Compress Spring, the inertia action effect of tup is strengthened, further increase the effect that stockbridge damper entirety prevents from vibrating.The arranging of impeller can also lay down a part of external force to the downward Action of Gravity Field of tup, can extend the useful life of tup and wire.

In figure, 1, left wheel hub, 2, wheel shaft, 3, impeller, 4, blade, 5, right wheel hub, 6, wire, 7, wire clamp clamping plate, 8, steel strand wire, 9, tup, 10, weakening spring, 11, power transmission clamping plate, 12, stockbridge damper.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.Following examples are only specific embodiment of the utility model, but design concept of the present utility model is not limited thereto, and all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection range.
As shown in Figure 1, wire vibration abatement of the present utility model, its concrete structure is as follows: the wire clamp clamping plate 7 of stockbridge damper 12 are connected with power transmission clamping plate 11 by weakening spring 10, the structure of power transmission clamping plate 11 is identical with the structure of wire clamp clamping plate 7, wire clamp clamping plate 7 and power transmission clamping plate 11 are arranged on wire 6, stockbridge damper 12 comprises wire clamp clamping plate 7, steel strand wire 8 and tup 9, wherein one end of steel strand wire 8 is arranged in tup 9, the other end and the wire clamp clamping plate 7 of steel strand wire 8 are fastenedly connected, the structure of tup 9 is as follows: the left wheel hub 1 and the right wheel hub 5 that are positioned at both sides, wheel shaft 2 is provided with between left wheel hub 1 and right wheel hub 5, wheel shaft 2 is set with rotatable impeller 3, the equidistant setting of blade 4 on impeller 3.The outer rim of blade 4 exceeds left wheel hub 1 and right wheel hub 5 outer rim 1.5-2 centimetre of the best.
Operation principle of the present utility model is as follows:
The wire clamp clamping plate of stockbridge damper are connected with power transmission clamping plate by weakening spring by the utility model, can absorb the vibrational energy of a part of wire, play the effect improving shockproof effect further.That is innovated by the integral structure of tup makes wheel hub, wheel shaft type structure into, and on wheel shaft sheathed impeller, like this under the prerequisite not changing tup overall weight, time on the External Force Acting to tup such as wind, rain, snow, hail of external force, impeller can lay down a part of external force, effectively reduces significantly waving of wire.Due to the setting of impeller and Compress Spring, the inertia action effect of tup is strengthened, further increase the effect that stockbridge damper entirety prevents from vibrating.The arranging of impeller can also lay down a part of external force to the downward Action of Gravity Field of tup, can extend the useful life of tup and wire.
