Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural diagram of the present invention；
In figure: 1 steel anchor, 2 insulator chains, 3 spools, 4 drainage plates, wire clamp on 5,6 retaining rings, 7 connecting rods, 8 drop wire clips, on 9
Layer lug plate, 10 lower layer's lug plates, 11 connecting columns, 12 barber-pole stripes, 13 drainage wire casings, 14 wire casings, 15 bolts.
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Figure 1, a kind of copper-alloy stranded conductor is pressed from both sides with bracing cable, including steel anchor 1 and the insulator chain connecting with steel anchor 12, absolutely
Edge substring 2 has been connected through a screw thread connecting ring, and connecting ring is connect by cotton rope with spool 3, there is the recessed of fixed cotton rope outside spool 3
Slot, the lower section of connecting ring are vertically also connected with drainage plate 4 and parallel groove clamp, and drainage plate 4 is connected by retaining ring 6 and connecting ring
It connects, is connected between drainage plate 4 and parallel groove clamp by bolt nut.
Working principle: in use process, being fixedly connected by steel anchor 1 with electric pole, and connecting ring is connected by cotton rope and spool 3
It connects, spool is connect by cotton rope by the groove on spool 3 with connecting ring, on the one hand can stablize spool 3 fix in this way, another
Aspect not will increase the rugosity of spool 3, so as to avoid beam wind on influence caused by spool 3, improve safety in utilization, line
Then cable is guided by drainage plate 4 and parallel groove clamp to next link through wire-passing tube 3, to improve the convenience used.
Connecting ring in the present invention includes the connecting rod 7 being connected with insulator chain 2 and junction block, junction block and connecting rod 7
Between be bolted, junction block includes upper layer lug plate 9 and lower layer's lug plate 10, upper layer lug plate 9 and lower layer's lug plate
10 one end is integrally formed connection by connecting column 11, and connecting rod 7 is adopted between upper layer lug plate 9 and lower layer's lug plate 10
With this structure, cable can be stably fixed on junction block, it is ensured that in use process, wire clamp, which stablizes cable, to be fixed.
Have barber-pole stripes 12 outside spool 3 in the present invention, can make spool 3 along its length on wind-engaging cross section it is continuous
Variation；Strain clamp can also be made to be cladded with moon exterior feature irregular shape under clammy weather, change section along the hand of spiral,
So that aerodynamic effects caused by wind-force are interfered with each other and restricted, reduce its lift coefficient, lift coefficient curvilinear motion
It tends to be steady, the increase of resistance coefficient can make conducting wire consume more energy during the motion, advantageously reduce power transmission line
It waves probability and reduces transmission line galloping amplitude in road.
