The purpose of this utility model be provide a kind of anti-rotation earth wire pile, solve earth lead install when easy rotation phenomenon, with gram
Take problem present in background technology.
To achieve these goals, the technical solution of the utility model is：
A kind of anti-rotation earth wire pile, including earth wire pile and ground wire, earth wire pile is provided with installing hole, and ground wire includes an installation
Bar, ground wire is connected to earth wire pile by the fit structure of mounting rod and installing hole；It is provided with a gear above the installing hole of earth wire pile
Hardened structure, baffle arrangement is provided with locating slot near the side of installing hole, and ground wire is provided with the raised knot matching with locating slot
Structure.
It is preferred that coordinating for screw thread between installing hole and mounting rod.
It is preferred that installing hole is provided with a copper nut.
It is preferred that mounting rod is threaded rod.
It is preferred that also including the wing nut for fastening mounting rod.
It is preferred that baffle arrangement is perpendicular to the pile of earth wire pile.
It is preferred that locating slot is square groove, bulge-structure is square bulge-structure.
It is preferred that locating slot is arranged at the center of baffle arrangement lower surface.
It is preferred that ground wire is provided with the plane matching with baffle arrangement, bulge-structure is arranged at the center of plane.
The beneficial effects of the utility model are：Provide a kind of anti-rotation earth wire pile, carry rotation preventing mechanism, can be by ground wire
Head is prevented from tightening ground wire during wing nut and rotates together together with being firmly installed in earth wire pile, reduces ground wire and ground wire
The abrasion of staking contacting surface, reduces the loose contact problem that surface leads to because of oxidation, substantially increases the reliability of ground connection
Property is transformer station, in power plant the safety operation of operator provide reliable guarantee it is ensured that setting in transformer station, power plant
Standby safe operation, this utility model earth wire pile has very high economic effect and social benefit in actual use.

Specific embodiment
With reference to the accompanying drawings and examples this utility model is described further.
A kind of anti-rotation earth wire pile 1, including earth wire pile 1 and ground wire 2, earth wire pile 1 is provided with installing hole 11, and ground wire 2 wraps
Include a mounting rod 23, ground wire 2 is connected to earth wire pile 1 by the fit structure of mounting rod 23 and installing hole 11；The peace of earth wire pile 1
Dress is provided with a baffle arrangement 12 above hole 11, and baffle arrangement 12 is provided with locating slot 13 near the side of installing hole 11, on ground wire 2
It is provided with the bulge-structure 22 matching with locating slot 13.
Baffle arrangement 12 is arranged at the center of baffle arrangement 12 lower surface perpendicular to the pile of earth wire pile 1, locating slot 13,
Locating slot 13 is square groove.
Ground wire 2 is provided with the plane 21 matching with baffle arrangement 12, and bulge-structure 22 is arranged at the center of plane 21,
Bulge-structure 22 is square bulge-structure 22.
Coordinate for screw thread between installing hole 11 and mounting rod 23, specifically：Installing hole 11 is provided with a copper nut 3, installs
