Background technology
Power system is national lifeline engineering important component part, is occupied in national economy life very importantly
Position.With people's being continuously increased for electrical energy demands, electric power system scale also constantly expands, if power system is once on ground
Earthquake centre is destroyed, and not only can bring huge economic losses to country, and for the development of rescue work after shake also brings pole
Big inconvenience.And research shows that power transmission and transformation electric equipment belongs to weak link in earthquake.
Traditional transmission pole does not arrange shock-absorbing protecting measure, and is often formed with geological process and resonate, and causes
The breaking-up of the transmission pole in earthquake, the especially cantilever of transmission pole, so can result in power system paralysis.
The content of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of transmission pole cantilever to protect
Protection unit, can change the own frequency of transmission pole, reduce its vibration under geological process.
In order to achieve the above object, the technical scheme that the utility model is taken is：
A kind of transmission pole cantilever protection device, including transmission pole 8, the one of the symmetrical connection in the upper end of transmission pole 8
To cantilever 3, drag-line 2, the middle part of drag-line 2 and the connection of the upper end of the second drive link 5, the second transmission are connected between a pair of tops of cantilever 3
The lower end of bar 5 and the gear shaft 11 of gear 6 connect, and gear shaft 11 is connected by the drive link 4 of connecting rod 9 and first, gear 6 and
The indentation engagement on the top of one drive link 4, the lower end of the first drive link 4 and the electrostrictive actuator 7 for being fixed on the upper end of transmission pole 8
Connection, the top of cantilever 3 is provided with vibrating sensor 1, the output end of vibrating sensor 1 and the input of vibration receiving and processing device 12
End connection, vibrates the output end of receiving and processing device 12 and the input connection at current control center 13, current control center 13
Output end be connected with the signal input part of electrostrictive actuator 7, vibration receiving and processing device 12 and current control center 13
It is connected on transmission pole 8.
Described drag-line 2 is steel wire cable.
The first described drive link 4 is provided with chute 10, and connecting rod 9 can slide in chute 10.
The beneficial effects of the utility model are：
1st, this device takes full advantage of the principle of Based Intelligent Control, vibration signal is passed to into vibration by vibrating sensor 1 and is received
Processing meanss 12 and current control center 13, with the elongation of current control electrostrictive actuator 7, band moving gear 6 will make cantilever 3
Two ends stress is different, changes its natural frequency of vibration, it is to avoid the phenomenon of resonance occurs damages transmission pole, power system paralysis.
2nd, while according to Vibration Condition, adjusting electrostrictive actuator 7 makes it produce the power contrary with vibration, such cantilever
3 when vibrating upwards, and drag-line 2 loosens, and when moving downward, drag-line 2 is tightened up.Vibration amplitude is as much as possible reduced, reduces vibration.
