Description
Technical field
The utility model relates to the gentle breeze vibrationproof field of transmission line, particularly, relates to a kind of strong stockbridge damper that consumes energy.
Background technology
The aerial conducting wire that set up on highland is because the impact of aerial air-flow easily causes mechanical oscillation phenomenon, and mechanical oscillation cause that with gentle breeze the oscillation phenomenon of generation is the most frequent, this vibration usually causes short strand of the fatigue of wire, and then has influence on safe operation and the Financial cost of whole transmission line.
The actual wind speed that causes conductor vibration is also little, but it is longer to vibrate the lasting time, is generally a few hours, sometimes can reach a couple of days, thereby prevent from or reduce this vibration seeming particularly important for actual transmission of electricity demand.Prevent or reduce this vibration, just need to first understand and cause the needed characteristic of this vibration.General wind speed is steady, and wind direction is perpendicular to overhead transmission line, and aeolian vibration just more easily occurs, and landform open area also easily produces aeolian vibration in addition.For reducing the aeolian vibration phenomenon of wire, stockbridge damper is often installed on wire.
Although existing stockbridge damper is simple, vibration-isolating effect is not good, is in particular in, the hammer body of stockbridge damper swings up and down wire that the energy consumption bringing causes that wind brings, and to swing energy loss little, the mechanical oscillation that can not effectively disperse wire.For this problem, the utility model has been designed the stockbridge damper of the energy of the strong consumption aeolian vibration of a kind of energy.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of strong stockbridge damper that consumes energy, the hammer body of the strong stockbridge damper setting of this power consumption has multiple hammer bodies, this hammer body can be in aeolian vibration, the vibration of multiple different frequencies is provided, thereby the energy that the more aeolian vibration that can dissipate brings, the existence of multiple hammer bodies can expand frequency response width, thereby can consume the different frequency energy of aeolian vibration, reaches the object of vibrationproof.
The technical scheme in the invention for solving the above technical problem is:
A kind of strong stockbridge damper that consumes energy, comprise wire clamp, steel strand wire, hammer body, wire clamp comprises wire clip body, wire clamp cover plate, wire clamp lower end, and wire clamp spiral shell bullet pad, the inner face of wire clip body upper end is arc, the inner face of wire clamp cover plate upper end is arc groove, the upper end interlock of the upper end of wire clip body and wire clamp cover plate forms perforation under an annular and passes for cable, wire clamp spiral shell bullet pad through wire clip body lower end and wire clamp cover plate lower end to adjust the degree of engagement of wire clip body and the wire clamp cover plate cable that is locked, wire clamp lower end is connected with wire clamp cover plate, wire clamp lower end is provided with the lower perforation of passing for steel strand wire,
Steel strand wire are positioned at the below of wire clamp and are fixedly connected with wire clamp through lower perforation, hammer body is identical 2 two ends that are separately positioned on steel strand wire, the steel strand wire passage that described hammer body comprises tup, is connected to the hammer body on tup and passes for steel strand wire, hammer is as the slice with circular arc termination, hammer body is at least 4 and be symmetrically distributed on tup, and is at least between the described hammer body of 4 different in size.
It is in order to consume the vibrational energy on aerial cable that stockbridge damper is arranged on cable, makes cable can reach energy balance under very little amplitude, thereby reduces the vibration of cable.Traditional stockbridge damper only has 2 resonance frequencys to consume the energy of aeolian vibration, and this consumed energy is too small and weak, does not reach desirable effect.The utility model arrange at least with 4 hammer bodies hammer body, and hammer body is different in size, such design can make stockbridge damper in vibration processes, have multiple resonance frequencys, can meet the demand of the aeolian vibration energy dissipation of different resonance frequencys, thereby dissipation energy is strong.
The end of steel strand wire is spiral-shaped.
Steel strand wire passage in the tup of hammer body comprises the straight line portion that the end of mushroom cavity is connected with end, and the inwall of the straight line portion of steel strand wire passage is also for spiral-shaped and terminations steel strand wire match.The spiral-shaped coupling of steel strand wire and hammer body can be strengthened the firm connection causing because of phase mutual friction between steel strand wire and hammer body on the one hand, the energy that also has on the other hand friction can loss aeolian vibration to pass in vibration because between steel strand wire and hammer body, thereby can more play the effect of vibrationproof.
In the termination of the mushroom cavity of steel strand wire passage, also having built cement is fixed on steel strand wire in hammer body.In the mushroom head of the mushroom cavity of the steel strand wire passage in hammer body, having certain cavity gap can be cast in cement wherein, strengthens the connection between steel strand wire and hammer body, prevents that hammer body from coming off from steel strand wire.
Hammer body bottom is also provided with osculum.Can prevent hammer body corrosion thereby the osculum that hammer body bottom arranges can exclude the water entering in hammer body in time, ensure that the resonance frequency of hammer body can not changed easily.
To sum up, the beneficial effects of the utility model are:
1, the utility model arrange at least with 4 hammer bodies hammer body, and hammer body is different in size, such design can make stockbridge damper in vibration processes, have multiple resonance frequencys, can meet the demand of the aeolian vibration energy dissipation of different resonance frequencys, thereby dissipation energy is strong.
2, the utility model is simple in structure, cheap, can be used in large-scale production and application.
