Specific embodiment
To make the structure feature to the utility model and the effect of being reached has a better understanding and awareness, to compared with
Good examples and drawings cooperate detailed description, are described as follows:
As shown in Figure 1 and Figure 2, a kind of insulated type drainage thread for the weather-proof angle steel tower of transmission line of electricity of the utility model is fixed
Fitting, the fixed fitting of drainage thread includes screw rod 1 and the nut 4 with the cooperation of screw rod 1, including is arranged on screw rod 1 for fixing
The fixture 5 of insulation tube 6, the fixed fitting of drainage thread are movably arranged on tower body tabula by screw rod 1 and 4 mating reaction of nut
On frame.
Insulation tube 5 has for the through-hole 10 by drainage thread, and drainage thread is passed through from through-hole 10；Drainage thread fixes fitting
It further include the gasket 2 matched with screw rod 1, nut 4, spring pad 3.
The fixed fitting of the drainage thread can be fine by the collective effect of the components such as screw rod 1, nut 4, fixture 5, insulation tube 6
Fixation drainage thread, under high wind weather long-play, the fixed fitting of drainage thread is not susceptible to swing that (drainage thread swing can make
Drainage thread causes to corrode close to weathering steel), lightning protection effect is improved, is conducive to protect transmission line of electricity and electrical equipment, fixture 5, absolutely
The design of edge pipe 6 avoids generation primary battery anti-so that drainage thread and weather-proof steel material angle steel tower form insulating materials physical isolation
It should cause to corrode；
Traditional wire clamp is after fixed drainage thread, and from tower top to tower bottom, the distance of drainage thread and tower body is just fixed.According to
Lightning current transmission skin effect, drainage thread arrangement closer to outside, lightning current protection effect is better.Therefore, if drainage thread
Spacing between tower body is excessively close, and drainage effect decline is unfavorable for lightning protection；If the spacing between drainage thread and tower body is too far,
Especially tower body bottom, distance of the drainage thread on the outside of tower body increase, and will result directly in the increase of ground perimeter security distance.
Simultaneously as the complexity of transmission line tower structure, if the fixed fitting of drainage thread freely can be installed or be adjusted,
The time of construction and installation will be effectively reduced, the disassembly and debugging of device of being more convenient for.The fixed fitting of this practical drainage thread passes through screw rod
It is movably arranged on nut mating reaction on the frame of tower body tabula, by adjusting screw rod 1, nut 4, can freely adjust
Distance of the drainage thread apart from tower body adjusts the distance that drainage thread is suitable for apart from tower body in the middle part of tower body eminence and tower body, and enhancing is drawn
Effect is flowed, lightning protection effect is improved；In tower body bottom, the distance that drainage thread is suitable for apart from tower body is adjusted, reduces ground perimeter security
Distance reduces lightning-arrest cost.
Fixture 5 is capable of fixing at least one drainage thread, as shown in figure 4, feelings when fixture 5 is capable of fixing a drainage thread
Shape.
The fixed fitting of drainage thread further includes movable plate, and the fixed fitting of drainage thread directly connect with frame or pass through movable plate
It is connect with frame.
As shown in Figures 2 and 3, movable plate is L-type movable plate 7 or H type movable plate 71；One end of H type movable plate 71 and spiral shell
Bar 1 connects, and the other end is connect by adjusting bolt I 8 with frame；One end of L-type movable plate 7 is connect with screw rod 1, and the other end passes through
Adjust bolt II 9, nut 4 is connect with frame.
When installing drainage thread: drainage thread fixes installation when on the frame of tower body tabula by drainage thread, if do not had
There is movable plate, need to punch on frame, the design of H type movable plate 7, L-type movable plate 71 can save the behaviour punched on frame
Make, it is convenient and practical.
