Description
The application is entitled：The anti-bird from building nest mechanism of electric wire based on small angle rotation structure, the applying date be：2016 8
Month 20 days, Application No.：201610690907.4 patent of invention divisional application.
Technical field
The invention belongs to high-voltage safety technical field, more particularly to a kind of anti-bird of electric wire based on small angle rotation structure
Nest mechanism.
Background technology
The electric wire being currently installed in high-tension electricity transmission tower cannot typically be rotated, and electric wire is fixed on electric wire tower, on the one hand
Nearby easily there are Bird's Nest or other foreign matters in electric wire tower, and cleaning is difficult；And if cleared up not in time, then by detonator circuit
Failure causes to have a power failure；On the other hand, if wind speed is very big, electric wire is blown, because electric wire is fixedly mounted on electric wire tower, wind-force mistake
The big electric wire that easily occurs fractures.
The present invention designs a kind of anti-bird from building nest mechanism of electric wire based on small angle rotation structure and solves as above problem.
The content of the invention
To solve drawbacks described above of the prior art, the present invention discloses a kind of anti-bird of the electric wire based on small angle rotation structure
Nested mechanism, and it is realized using following technical scheme.
A kind of anti-bird from building nest mechanism of electric wire based on small angle rotation structure, it is characterised in that：It include electric wire, driving lever,
Universal joint, rotating disk, cord, crossbeam, the first guide rod plectane, external thread rod, ring, scroll spring, change, pillar, second
Guide rod plectane, change fixture block, threaded rod fixture block, guide rod, lead ring hole, internal thread hole, the top of its B-C post are provided with crossbeam, horizontal
The self structure at beam both ends and the structure installed are identical, and for the structure of either end, external thread rod one end is arranged on
Crossbeam one end, the first guide rod plectane, rotating disk, the second guide rod plectane are sequentially installed with external thread rod；At the center of rotating disk
Internal thread hole is provided with, the external screw thread of external thread rod and the internal thread of internal thread hole are coordinated by screw thread；Guide rod is led installed in first
Between bar plectane and the second guide rod plectane and guide rod axis and external thread rod diameter parallel, lead ring hole, guide rod are provided with rotating disk
Passed through from lead ring hole；Change is arranged on the outer edge surface of the second guide rod plectane, and change fixture block, external thread rod are provided with change
One end threaded rod fixture block is installed；One end of scroll spring is fixed on threaded rod fixture block, and the other end is fixed on change fixture block
Upper and scroll spring side contacts with the plate face of the second guide rod plectane side；Be installed with driving lever in rotating disk, change it is outer
Ring is installed, driving lever passes from ring on edge face；Circular hole is provided with rotating disk, one end of electric wire is arranged on by universal joint
In circular hole；Between two rotating disks, the electric wire of crossbeam both sides is connected cord by cord.
Above-mentioned universal joint includes first rotating shaft, annulus, electric wire set, the second rotating shaft, and wherein annulus is symmetrical by two

When only moving, scroll spring pulls change return, drives driving lever to make rotating disk return by the ring in change.
As the further improvement of this technology, three, four electric wires can be installed in above-mentioned rotating disk, can be according to specific electricity
Line condition of construction determines.
It is opposite as the further improvement of this technology, the hand of spiral of above-mentioned two external thread rod.So that electric wire drives
When rotating disk rotates, the rotating disk of crossbeam both sides all moves to middle direction.A tensioning function is played to electric wire, prevents electric wire
Between because reverse occur short circuit.
As the further improvement of this technology, it to rotate disk axis is the center of circle into one section of circular arc that above-mentioned lead ring hole, which is,
Hole.Lead ring hole only has a bit of, can limit rotating disk with small angle rotation.
As the further improvement of this technology, the electric wire of above-mentioned crossbeam both sides is connected by connector with cord.Even
Electric wire can be connected by fitting with cord.Connector connected mode between traditional electric wire, it can ensure that electric wire connects
The resistance of the resistance approximation electric wire at place in itself.
Relative to traditional high-voltage safety technology, the electric wire of middle cross beam both sides of the present invention passes through connector and cord phase
Connection；Internal thread hole is provided with the center of rotating disk, the external screw thread of external thread rod and the internal thread of internal thread hole are matched somebody with somebody by screw thread
Close；When wind blows electric wire, electric wire drives rotating disk to be rotated around external thread rod, and the rotating disk of crossbeam both sides is drawn close to centre, from
And by electric wire straightening, avoid touching in electric wire rotation process；It when becalming only, can return rotating disk by scroll spring
Position.The present invention is simple in construction, by rotating disk Small-angle Rotation with the wind, can avoid electric wire tower nearby due to Bird's Nest or other different
Fault caused by thing；With stronger practical function.
