Specific embodiment

For technology contents, structure feature, realization principle and the objects and the effects that the utility model is described in detail, with Lower combination embodiment simultaneously cooperates attached drawing to be explained in detail.

As shown in Figures 1 to 4, the utility model discloses a kind of attachment device of ground wire for fixing in power transmission line, Including a pair of conductive intermediate plate 10 and the connecting line 2 being electrically connected at least one of a pair of of intermediate plate 10, the i.e. company One end of wiring 2 can be connect with one in a pair of of intermediate plate 10, can also simultaneously be connect with two intermediate plates 10, connecting line 2 it is another End is electrically connected with power transmission line pylon (not shown), and the effect of connecting line 2 is that the lightning current on ground wire 3 is transmitted on pylon, Big ground is transmitted to via pylon again.A holding tank 11 is relatively set on a pair of of intermediate plate 10 respectively, holding tank 11 is along ground wire 3 Arranged direction extends, and after a pair of of intermediate plate 10 is docking together, ground wire 3 is held in a pair of of holding tank 11.

The attachment device for the ground wire that the utility model is used to fix in power transmission line will be transmitted electricity using a pair of opposite intermediate plate 10 The clamping of ground wire 3 in line wherein, when installation, as long as two intermediate plates 10 are fixed on after two intermediate plates 10 are docked on ground wire 3 Together, since intermediate plate 10 is conductive, lightning current can be transmitted on the connecting line 2 being electrically connected with intermediate plate 10 by intermediate plate 10, Then it is transmitted in the earth via connecting line 2.It follows that the fixture 1 with above structure not only facilitates installation, and due to Ground wire 3 is held in the holding tank 11 of a pair of of intermediate plate 10, and in installation and use process, intermediate plate 10 will not cause ground wire 3 Damage.In addition, comparing traditional preformed armor rods, intermediate plate 10 and the contact area of ground wire 3 are bigger, when the electric current warp for having thunder and lightning to generate When crossing intermediate plate 10, electric shock intensity suffered by unit area is smaller on intermediate plate 10, it is not easy to be blown, prolong the service life.By In the cross section of ground wire 3 to be round, in order to enable intermediate plate 10 better adapts to ground wire 3, preferably, the cross section of holding tank 11 Semicircular in shape.

As shown in figure 4, in order to which preferably a pair of of intermediate plate 10 is fixed together, to clamp ground wire 3, in the present embodiment, often The fixinig plate 12 vertical with the extending direction of intermediate plate 10, the upper and lower ends difference of fixinig plate 12 are provided on the outer wall of one intermediate plate 10 It is provided with an interconnecting piece 120, is provided with first through hole 121 on interconnecting piece 120, is consolidated a pair of of intermediate plate 10 by first through hole 121 It is scheduled on together, one end of connecting line 2 is connect with interconnecting piece 120.When two intermediate plates 10 are docking together, two intermediate plates 10 On the axis of first through hole 121 be located along the same line, be through in the first through hole 121 on two intermediate plates 10 using fixing piece It can be fixed.Preferably, the both ends of connecting line 2 are respectively arranged with a connection terminal 20, is provided on connection terminal 20 Two through-holes 200, when connecting line 2 is connect with interconnecting piece 120, the second through-hole 200 is opposite with first through hole 121, using bolt part 4 are threaded through in the second through-hole 200 of first through hole 121 and connecting pin on two fixinig plates 12, by a pair of of intermediate plate 10 and connection One end of line 2 is fixed together.

As shown in Figures 3 to 5, since the pylon of power transmission line is generally relatively high, wind-force suffered by power transmission line is bigger, therefore The fixture 1 being clipped on ground wire 3 is easy to happen vibration, and the bolt part 4 on intermediate plate 10 is easy to rotate to loosening direction in vibration, So that fixture 1 fluffs, even disengaging ground wire 3 is additionally provided on interconnecting piece 120 for preventing in order to avoid the generation of this phenomenon The anti-looseness mechanism that bolt part 4 rotates.Preferably, anti-looseness mechanism is included in 121 array cloth of ring first through hole on interconnecting piece 120 Several grooves 50 set and the gasket 52 being set between bolt part 4 and interconnecting piece 120 are provided on gasket 52 several to connection The protrusion 51 that portion 120 is stretched out, protrusion 51 to corresponding, are mutually clamped by raised 51 with groove 50, limitation gasket with groove 50 52 rotation, is provided with the third through-hole 53 passed through for bolt part 4 on gasket 52, the edge setting of third through-hole 53 it is several to Upper raised 51 elastic piece 54, elastic piece 54 are used to fix bolt and gasket 52 together.After bolt part 4 is fastened, bolt Gasket 52 and interconnecting piece 120 are crimped together by part 4, since the head of bolt part 4 is fixed by elastic component, bolt part 4 It cannot rotate with respect to gasket 52, while gasket 52 can not opposing connections under the interaction of protrusion 51 and groove 50 120 rotate, to achieve the purpose that limit pitch of bolts rotation.

Above disclosed is only the preferred embodiments of the utility model, cannot limit the utility model certainly with this Interest field, therefore equivalent variations made according to the patent scope of the utility model still falls within the utility model and covered Range.
