Description
Technical field
The present invention relates to steel tower protective device technical field, more particularly to a kind of windproof vibration absorber of iron tower of power transmission line.
Background technology
Supporting point of the steel tower as transmission line of electricity, plays highly important effect in power construction.But electric power pylon
Can be in adverse weather condition（High wind, anxious rain, severe snow, earthquake etc.）Lower generation acutely vibration, even results in steel tower deformation or fracture.
In coastal area, it is contemplated that the more frequent and higher wind intensity factor of typhoon, when high wind is to attack, steel tower is likely in wind
Collapse under power effect, once tower occurs, large-area power-cuts will be caused, and fault correction time is grown, and is not only produced direct
Economic loss, can also serious threat power grid safe and stable operation.
Traditional draught exclusion device is mainly resisted by way of reinforcing steel tower column foot or increase shaft tower size to improve steel tower
Wind performance, but the engineering cost of costliness will be caused.
The content of the invention
The deficiency for more than, the present invention provide a kind of windproof vibration absorber of iron tower of power transmission line, are acted on realizing in high wind
Under protection to steel tower, reduce the Oscillation Amplitude of steel tower, avoid the occurrence of down the serious electric power accident such as tower and occur.
To reach above-mentioned purpose, the present invention adopts the following technical scheme that：
A kind of windproof vibration absorber of iron tower of power transmission line, including mass block, suspension wire, hydraulic damper, air velocity transducer
And control computer；The mass block is suspended on steel tower by the suspension wire, hydraulic damper two difference
It is connected with the mass block and tower body, the air velocity transducer is installed on steel tower, hydraulic damper and the wind speed sensing
Device is connected with the control computer.
Further, the mass block is steel ball.
Further, the suspension wire is more, and the more suspension wires are uniformly connected to the mass block
Surrounding.
Further, the hydraulic damper is four groups, is connected to the top, bottom and correspondence of the mass block
Both sides.
Further, the mass block hangs in steel tower more than 2/3 and highly locates.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention provides a kind of windproof vibration damping of iron tower of power transmission line
Device, the energy of part wind is offset using mass block and hydraulic damper, and reduce steel tower waves degree, improves the steady of steel tower
It is qualitative, occur so as to avoid the occurrence of down the serious electric power accident such as tower.
Brief description of the drawings

Fig. 3 is the schematic diagram that the preferred embodiment of the invention is installed on steel tower, and wherein control computer is not drawn into.
Wherein, it is labeled as shown in figure：1- mass blocks, 2- suspension wires, 3- hydraulic dampers, 4- air velocity transducers,
5- control computers, 6- steel towers.
Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes.Obviously, described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment, belongs to the scope of protection of the invention.
Fig. 1, Fig. 2 and Fig. 3 are refer to, the preferred embodiment of the invention provides a kind of iron tower of power transmission line windproof vibration damping dress
Put, including mass block 1, suspension wire 2, hydraulic damper 3, air velocity transducer 4 and control computer 5；Mass block 1 passes through outstanding
Hang hawser 2 to be suspended on steel tower 6,3 two of hydraulic damper is connected with mass block 1 and tower body 6 respectively, air velocity transducer 4
On steel tower 6, hydraulic damper 3 and air velocity transducer 4 are connected with control computer 5.Wherein, as preferable reality
Example is applied, mass block 1 is steel ball, and steel ball density is high, and quality is big, and the mass block 1 of spherical class is particularly suitable for pair of other connected components
Claim, be uniformly arranged；Suspension wire 2 is 2, and 2 suspension wires 2 uniformly, are symmetrically connected to the surrounding of mass block 1；Hydraulic pressure
Damper 3 is four groups, is connected to the top, bottom and corresponding both sides of mass block 1, and this set causes four groups of hydraulic pressure
Damper 3 is uniformly distributed in mass block 1 up and down, and hydraulic damper 3 can either be realized to the comprehensive equal of mass block 1
Even effect；Mass block 1 hangs in steel tower more than 2/3 and highly locates；Control computer 5 may be mounted on steel tower 6, can also pacify
Dress on the ground, in this preferred embodiment, install on the ground by control computer 5.
During implementation, cause steel tower run-off the straight, shake when the air velocity transducer 4 on steel tower 6 monitors that wind regime has
When the trend of action, control computer 5 drive hydraulic damper 3 come regulate and control mass block 1 along wind opposite direction tilt or
Rock, so that the swaying direction of mass block 1 and steel tower 6 are on the contrary, have the function that reduction or elimination steel tower 6 are tilted or vibrated；
When air velocity transducer 4 monitors that wind regime is good, steel tower 6 will not run-off the straight or shake, 5 locking hydraulic pressure of control computer at this time
Damper 3, mass block 1 will not be swung.By this set, the protection to steel tower 6, drop under high wind effect can be realized
The Oscillation Amplitude of low steel tower 6, avoids the occurrence of down the serious electric power accident such as tower and occurs.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, any
