Abstract
The utility model discloses a grounding rod of an overhead transmission line comprising a pincer like wire clamp, a connecting wire, a supporting rod, a wing-shaped screw, a multidirectional adapter, an operation handle, and a grounding wire nut. The pincer like wire clamp is convenient to open and close, and an arc-shaped design of an inner edge can be used to guarantee the full contact with the grounding wire, the multidirectional adapter can be used to connect the ground rod with circuits in any direction in a suspended manner conveniently. The grounding rod provided in the utility model can be used to solve the problem of the difficult suspension connection of the overhead transmission line grounding wire, especially the high voltage overhead transmission line grounding wire.
Description
Technical field
The utility model relates to a kind of earth rod of overhead transmission line, can conveniently carry out especially articulating of ultra-high-tension power transmission line earth connection of overhead transmission line.
Background technology
Overhead transmission line is due to its special mounting means, makes that to articulate earth connection more difficult, and operating personnel often need to take dangerous posture just can complete to articulate to connect, and operating efficiency is also very low.
Summary of the invention
The purpose of this utility model is to provide a kind of earth rod of overhead transmission line.
The technical scheme that realizes above-mentioned purpose is: a kind of earth rod of overhead transmission line, comprise pincerlike ply-yarn drill, connecting line, support bar, wing screw, multi-direction adapter, operating handle and earth connection nut, wherein, described pincerlike ply-yarn drill is located at the upper end of described support bar, described multi-direction adapter is located at the lower end of described support bar, described connecting line connects described operating handle and described pincerlike ply-yarn drill, described wing screw is fixed described operating handle, and described earth connection nut is arranged on described pincerlike ply-yarn drill.
The utility model can conveniently carry out especially articulating of ultra-high-tension power transmission line earth connection of overhead transmission line.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing to describing preferred embodiment of the present utility model.
Please refer to Fig. 1, provided a kind of earth rod better embodiment of overhead transmission line in figure, comprise pincerlike ply-yarn drill 1, connecting line 2, support bar 3, wing screw 4, multi-direction adapter 5, operating handle 6 and earth connection nut 7, wherein, pincerlike ply-yarn drill 1 is located at the upper end of support bar 3, and multi-direction adapter 5 is located at the lower end of support bar 3, connecting line 2 attended operation handles 6 and pincerlike ply-yarn drill 1, wing screw 4 fixing operation handles 6, earth connection nut 7 is arranged on pincerlike ply-yarn drill 1.
The utility model basic principle is: pincerlike ply-yarn drill 1 clamps earth connection, but arc inner edge enlarge active surface reduces contact resistance; The steel cable of connecting line 2 attended operation handles 6 and pincerlike ply-yarn drill 1 is opened pincerlike ply-yarn drill 1 when pinching operating handle 6; Support bar 3 is hollow round steel pipe, and effect is to support pincerlike ply-yarn drill 1; Wing screw 4 fixing operation handle 6 angles; Multi-direction adapter 5 connects support bar 3 and operating handle 6; Operating handle 6 can make pincerlike ply-yarn drill 1 open, and the angle when not being subjected to external force between operating handle 6 remains on fixed value; Earth connection nut 7 connects the earth connection that is embedded in the earth.
Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details in embodiment should not consist of restriction of the present utility model, and the scope that the utility model will define with appended claims is as protection range of the present utility model.
