Description
Technical field
The present invention relates to a kind of stockbridge damper of overhead transmission line, and in particular to a kind of quake protection of adjustable resonant frequency
Hammer.
Background technology
The aeolian vibration of power transmission line and the wind shake of power transmission tower can often cause the stranded broken string of power transmission line, shaft tower node continuous damage
Etc. the great failure of harmfulness, serious large area blackout is repeatedly impacted.Charming appearance and behaviour overhead transmission line conductor vibrates
There are three kinds of forms:Aeolian vibration, subspan oscillation and wave, the aeolian vibration of wherein wire occurs the most frequent, influence
It is maximum.The aeolian vibration of wire is because when wind vertically blows over wire, the periodicity " toll bar vortex " produced behind in wire swashs
The effect of encouraging, produces the active force of vertical wires and wind direction on wire so that wire produces aeolian vibration.If circuit gentle breeze shakes
Dynamic control is improper, will make transmission line of electricity that the failures such as stranded wire fatigue, gold utensil abrasion, shaft tower component damage easily occur,
Larger harm is brought to line security.Domestic and foreign experience shows that overhead transmission line is in the landform bar such as coastal, desert, cross a river, over strait
Serious aeolian vibration is susceptible under part, the interior fatigue that this may result in was stranded at two weeks for the wire without vibrationproof safeguard measure,
Not only increase the power attenuation of transmission line of electricity, cause power wastage, or even cause wire fracture and cause the loss of power accident, serious prestige
Coerce trolley line service life, or even transmission line of electricity safety.
The antivibrator of wire is used as one of main tool for preventing conductor vibration, self-resonant frequency and transmission of electricity when antivibrator
When the vibration frequency of circuit matches, the resonant frequency of overhead transmission line can be well reduced.But current antivibrator is only capable of
Several resonant frequencies are matched, resonance vibration damping cannot be played a part of for other most frequencies.
The content of the invention
Antivibrator the invention aims to solve current is only capable of matching several resonant frequencies, for other most frequencies
Rate cannot play a part of the problem of resonance vibration damping.And then a kind of quake protection hammer of adjustable resonant frequency is provided.
The technical scheme is that：A kind of quake protection hammer of adjustable resonant frequency includes wire clamp component and shield line
Set, wire bushing is sleeved on wire, and wire clamp component is arranged on wire bushing, and the quake protection hammer also includes middle supporting plate, two
Individual resonance device, first connecting rod, bottom plate, the first tumbler, screw rod, the second tumbler, pressing plate, stepper motor, worm gear, second
Connecting rod and swingle, middle supporting plate are connected by screw with the lower end of wire clamp component, and bottom plate is arranged on the lower end of middle supporting plate,
Stepper motor is arranged on bottom plate by pressing plate, and the output end of stepper motor is connected with screw rod, and the two ends of screw rod pass through respectively
First tumbler and the second tumbler are supported and are rotatably connected, and worm gear is arranged on the bottom plate above screw rod and is nibbled with screw rod
Close, be may be rotatably mounted in the middle part of swingle on middle supporting plate, the two ends of swingle respectively with one end of first connecting rod and second
One end of connecting rod is rotatably connected, and the other end of first connecting rod and the other end of second connecting rod can turn with a resonance device respectively
Dynamic connection.
The present invention has the following effects that compared with prior art：
1. screw rod of the invention, swingle, first connecting rod, second connecting rod, gland and steel strand wires constitute a machinery
Transmission mechanism.By the stretching motion for being changed into steel strand wires of stepper motor.Adjusted by controlling the rotation of stepper motor
Save the extension elongation of steel strand wires.The resonant frequency of the elastic vibration constituted due to weight and steel strand wires stretches out outermost with steel strand wires
The top concave wheel group on side and the distance dependent of bottom concave wheel group, therefore can just control the antivibrator by controlling stepper motor
Resonant frequency.Simultaneously because the self-locking effect of worm-and-wheel gear, the worm-and-wheel gear being made up of swingle and swingle
It is capable of the extended length of auto lock steel strand wires.Without being further added by retaining mechanism, the installation weight of saving.The device by weight and
The resonance mechanism that steel strand wires are constituted.By the way that second connecting rod and first connecting rod to be connected respectively to the two ends of swingle, when control is revolved
Bull stick can simultaneously control two resonant frequencies of weight when rotating, and the continuously adjustabe of antivibrator resonant frequency be realized, with suitable
Answer the change of line vibration frequency.
2. the present invention can easily continuously adjust the resonant frequency of antivibrator, reach the matched well with line vibration.
Changing traditional antivibrator can only realize the limited shortcoming of resonant frequency, by continuously adjustabe regulation vibrator resonance frequently
Rate, is easy to be realized by automatic control device the function of antivibrator self adaptation vibrationproof.
3. the present invention uses worm gear screw-rod structure, while transmission is reached can also automatic blocking keeping what is regulated
Resonant frequency is constant.
4. simple structure of the present invention, it is easy to accomplish, it is with low cost.
