Detailed description of the invention
It is further described the present invention is novel with specific embodiment below in conjunction with the accompanying drawings.
As it can be seen, a kind of tension type transmission line protection system, including catch net 1, carrying rope 2, wave wind rope 4, earth anchor 8
System, wherein catch net 1 is arranged between N the tower 15 and N+1 tower 16 of newly-built circuit, is crossed over pitching above power circuit；
Catch net 1 is carried arranged by carrying rope 2, wave wind rope 4, earth anchor 8 system, sets carrying rope 2 cross-arm hanging point positions by project situation
Put, carry rope 2 ground angles, wave wind rope 4 ground elevation, catch net 1 height, wire bearing down, then calculate in rope force system
The theoretical value of each rope, fixing-line device 1 that earth anchor 8 system includes being sequentially connected with, lever hoist 6, draw-bar donamometer 7, earth anchor 8.
Wherein catch net 1 material is φ 8 and above continuous synthetic fibre kernmantle, with several more than horizontal spacing 2.0m, and longitudinal two
The catch net 1 of rhizosphere rope composition, all longitudinal ends of catch net 1 or laterally end make rope nose-ring, nose-ring interior diameter 80mm, outward
Smearing epoxy resin, nose-ring can penetrate carrying rope 2 successively.
Carrying rope 2 is Di Nima sheath rope, and the raw material of its fiber is ultra high molecular polyethylene, through gel spinning process system
Become, select specification Φ 12 and more than, carrying rope 2 does strain insulator hanging wire at N+1 tower 16, at N tower 15 through hanging pulley 9, to ground
Anchor 8 system strain insulator.
Carrying rope 2 earth anchor 8 systems are set in N tower 15 side, balance bracing wire (or earth anchor 8 system) are set at N+1 tower 16,
Surrounding at catch net 1 coverage area arranges wave wind rope 4 earth anchor 8 system.Carrying rope 2 earth anchor 8 systems press the apolegamy of 30kN load, wave
Wind rope 4 earth anchor 8 system presses the apolegamy of 15kN load, and the apolegamy of 30kN load is pressed in balance bracing wire.
As a example by N tower 15, be provided with supporting device thereon, supporting device include draw ring fixture 10, hang pulley 9,
Double hook spoolers 11 and the fixing-line device 2 12 drawn for jury anchor, draw ring fixture 10 is installing link hardware fitting on the main material of cross-arm, uses
In hanging double hook spooler 11, hanging pulley 9 and fixing-line device 2 12；Hang pulley 9 to be fixed by described draw ring fixture 10, be used for holding
Carry rope 2 strong points；Double hook spoolers 11 are used for transmitting suspension pulley 9 downforce to cross-arm above；Fixing-line device 2 12 is for tower
Face anchor carrying rope 2, make carrying restrict 2 ends depart from earth anchor 8 systems.All gold utensil devices use GB/T 700 trade mark to be Q235A steel
Manufacture.
Its installation steps are as follows: first pulled out from draw drum by strop, through the suspension pulley being arranged on N steel tower
9, then strop is hung on the line hanging mechanism of multi-rotor aerocraft, after aircraft arrives N+1 steel tower, pass through radio
Controlling to guide becket bridle to depart from, then end is through suspension pulley 9 to the ground being arranged on N+1 steel tower, at N+1 steel tower
Place's strop is connected with carrying rope 2 or danish seine rope, and then at N tower 15, ground artificial returns traction conductor rope, carries rope 2, danish seine
Restrict and set up by root.Carrying rope 2 does strain insulator on N+1 steel tower and connects, and is connected to earth anchor 8 system through cross-arm pulley at N steel tower,
Danish seine rope does interim anchor with the ferrum of both sides.
Catch net 1 operates, and is lived by carrying rope 2 anchors with fixing-line device 2 12 on N tower 15, and carrying rope 2 is freed earth anchor 8 and is
System, returns back out the suspension pulley 9 on tower, and N tower 15 ground fallen by tail rope.The most successively catch net 1 nose-ring is penetrated carrying rope 2,
Then being threaded back through on tower hanging pulley 9 by carrying rope 2, ground artificial tightens up carrying rope 2, and catch net 1 promotes and is suspended on fixing-line device two
12 and pulley room, then carrying rope 2 connection earth anchor 8 systems, continue to tighten up spooler, after carrying rope 2 ground are painstaking, release on tower
Fixing-line device 2 12.
After catch net 1 hangs up carrying rope 2, then endless rope 3 tangles catch net 1 medial ends, follows at N+1 tower 16
Endless cable 3 take-up, catch net 1 is pulled to protection zone and moves, and at catch net 1 end continuous extension endless rope 3, refers to when catch net 1 arrives
Location is put, and then endless rope 3 rope about belt tension on the tower of both sides is fixed.
Wave wind rope 4 floor projection direction is vertical, for rectangle area coverage with carrying rope 2；Wave wind rope 4 floor projection direction with
By across line parallel, for parallelogram area coverage.Risen wave wind rope hook 13 on blanking bar by multi-rotor aerocraft and catch carrying
Rope 2, then wave wind rope 4 is connected with earth anchor 8 system, and after 4 unrestrained wind ropes 4 hang up properly, regulation spooler applies tension force, catch net 1
Open, make catch net about 1 and work as position, produce carrying rope 2 downforce simultaneously.
Catch net 1 sets up final step, regulation carrying rope 2, the spooler of wave wind rope 4 earth anchor 8 system, observes draw-bar donamometer 7
Reading, meets design setting, simultaneously check protection net 1 height be spanned power circuit spacing compliant requirement,
Special messenger guard specified by the most each earth anchor 8.
Above are only the specific embodiment that the present invention is novel, but the novel design concept of the present invention is not limited thereto, all
Utilize this to conceive the change that carry out unsubstantiality novel to the present invention, the row invading the novel protected scope of the present invention all should be belonged to
For.
