Description
Technical field
The overhead wire that the utility model relates to a kind of marmem driving reverses deicer.
Background technology
China is subjected to macroclimate and mima type microrelief, microclimate condition effect, and the ice damage accident frequently takes place.Increase because of the sleet icing makes the loading of transmission line in many areas, cause broken string, accidents such as shaft tower, flashover, caused enormous economic loss.Equally, make somebody a mere figurehead connection and data wire and also may meet with same problem.
So far, also without any effective automation deicing system.In the prior art, the most frequently used method is: the power worker hands wooden stick, iron spanner or rubber bar and knocks icing electrical network, is electrical network " Reduction of Students' Study Load ".This method is the deicing most effectual way, carry out but must cut off the power supply, and progress slowly has danger.
Some trials have been made for addressing the above problem abroad.As: among the disclosed publication No.157997 of Norway, a kind of device that is used to remove the long-pending snow and ice on the power overhead network is disclosed, this device uses the arch unit that is suspended on the electric wire, along this arch unit of line tractive, removes the long-pending snow and ice on the line with rope thus.This also manually carries out, and this method and method difference with insulating bar collision power line above-mentioned are little, expend a large amount of manpowers.For another example: Swedish patent publication No.503724 discloses a kind of being used for by " deicer " of ice-covered power line, the solution that it proposed, also be based on along a kind of device of power line operation, this running gear has drum member, this cylinder makes power line crooked between cylinder, and the result makes ice coating broken and fall.Because this device must be along the power line tractive, so this method also is manual method, exists defective such as to take time and effort, efficient is low.U.S. Pat 6518497B1 discloses a kind of being used for by the method and apparatus of ice-covered power line, it proposes fixedly power line one end, the rotation power line other end is to the number of turns in the power line elastic range of appointment, discharge then, destroy the ice that is deposited on the power line to reach, require the end in the power line to rotate freely in this method, this has reduced the conduction reliability of overhead wire, and the fail safe of power line whole rotation also reduction electric armour clamp.
Summary of the invention
At above-mentioned prior art, the overhead wire that the utility model provides a kind of marmem to drive reverses deicer, and it utilizes the phase variable force bogie ceases to be busy of marmem to reverse, and relies on the torsional shear effect that the overhead wire icing is come off, automatically carry out, and the efficient height.
The utility model is achieved through the following technical solutions:
The overhead wire that a kind of marmem drives reverses deicer, comprise the lead fixed pipe, reverse the arm of force, driving spring, reverse connector, public connector and power-supply controller of electric, wherein, the lead fixed pipe is fixed on overhead wire mid portion (being non-end), reversing the arm of force fixedlys connected with the conduction stationary pipes, driving spring is by reversing connector and reversing the arm of force and fixedly connected, and corresponding driving spring connects by public connector on two overhead wires; Power-supply controller of electric is located on the overhead wire, and is connected with driving spring by power supply; Driving spring is that marmem is made.
The described arm of force that reverses is connected by reversing hold-down screw with reversing between the connector.
Be connected by public attachment screw between described driving spring and the public connector.
Described marmem can adopt that existing Cu system, NiTi are alloy etc. in the prior art, and the phase transition temperature scope of marmem is 60～100 ℃.
Workflow of the present utility model is as follows: when needs were removed icing on the overhead wire, power-supply controller of electric was started working, and power taking from the overhead wire is heated to driving spring through power line.Because driving spring is made by marmem, so be heated to phase transition temperature when above when marmem, undergo phase transition, driving spring twists.Driving spring reverses to drive and reverses the arm of force and the lead fixed pipe reverses around the axis of overhead wire, and overhead wire also reverses around axis together under the effect of reversing the arm of force.When being torqued into pre-set angle, at this moment overhead wire reverses in its elastic range, power-supply controller of electric stops power taking according to the windup-degree that detects and heats to driving spring, marmem is replied, the driving spring twisting resistance disappears, and driving spring, reverses the arm of force and the lead fixed pipe returns to original position under the effect of the elasticity of torsion restoring force of overhead wire.Can control power-supply controller of electric start and stop once more according to the removal situation of icing on the overhead wire, so circulation, overhead wire has just formed twist motion, thereby removes the icing on the overhead wire.
The utility model reverses (windup-degree is in the lead elastic range) fast by making middle certain part of overhead wire or certain several part, and then adjacent part is reversed in the other direction, make the icing on the overhead wire be subjected to shearing force to destroy, come off, to reach the purpose of deicing, after treating that twisting resistance disappears, overhead wire is returned to original state voluntarily under elastic reaction, further icing is sheared.Whole process need not manpower, and the automaticity height has simple in structure, easy to use, advantages such as efficient is high, long service life.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The overhead wire that a kind of marmem drives reverses deicer, comprise lead fixed pipe 4, reverse the arm of force 8, driving spring 4, reverse connector 2, public connector 6 and power-supply controller of electric 10, wherein, lead fixed pipe 4 is fixed on overhead wire 7 mid portions, reversing the arm of force 8 fixedlys connected with conduction stationary pipes 4, driving spring 1 is by reversing connector 2 and reversing the arm of force 8 and fixedly connected, and corresponding driving spring 1 connects by public connector 6 on two overhead wires 7; Power-supply controller of electric 10 is located on the overhead wire 7, and is connected with driving spring 1 by power line 9; Driving spring 1 is made for marmem, and the phase transition temperature scope is 60～100 ℃.
The described arm of force 8 that reverses is connected by reversing hold-down screw 3 with reversing between the connector 2.
Be connected by public attachment screw 5 between described driving spring 1 and the public connector 6.
Workflow is as follows: when needs were removed icing on the overhead wire 7, power-supply controller of electric 10 was started working, and power taking from the overhead wire 7 gives driving spring 1 heating through power line 9.Because driving spring 1 is made by marmem, so be heated to phase transition temperature when above when marmem, undergo phase transition, driving spring 1 twists.Driving spring 1 reverses to drive and reverses the arm of force 8 and lead fixed pipe 4 reverses around the axis of overhead wire 7, and overhead wire 7 also reverses around axis together under the effect of reversing the arm of force 8.When being torqued into pre-set angle, at this moment overhead wire 7 reverses in its elastic range, power-supply controller of electric 10 stops power taking and gives driving spring 1 heating, marmem is replied, and driving spring 1 twisting resistance disappears, and driving spring 1, reverses the arm of force 8 and lead fixed pipe 4 returns to original position under the effect of the elasticity of torsion restoring force of overhead wire 7, power-supply controller of electric 10 start and stop once more, so circulation, overhead wire 7 has just formed twist motion, thereby removes the icing on the overhead wire 7.
