Description
Technical field
This utility model relates to power equipment grounding technology field, particularly relates to one pole power ground.
Background technology
In power wiring systems, the ground connection performance quality of lightning protection electrode and reliability, direct shadow
Ringing electrical equipment, the normal of line facility effectively runs.At present, existing grounding body mostly is common circle
Steel or angle steel, or have selection screw-thread steel or Surface Machining to become screw-shaped, but the earthed surface of grounding body amasss
The least, affect impedance ground and effect.
Utility model content
This utility model is for above-mentioned the deficiencies in the prior art, it is provided that one pole power ground.
The technical scheme that this utility model solves above-mentioned technical problem is as follows: one pole power ground, including
Upper tube head, straight length and the conical head being connected as a single entity successively, it is characterised in that described straight length is provided with
Helical fin, described helical fin is welded by steel band helically coiling on the outer wall of described straight length,
It is additionally provided with concavo-convex gauffer on described helical fin, described straight length is welded with ground lead.
The beneficial effects of the utility model are: owing to being provided with helical fin on straight length, described spiral wing
Concavo-convex gauffer it is additionally provided with on sheet, under straight length equal length, same inner diameter premise, its contact surface area
Several times for common seamless steel pipe.Substantially increase earthing effect.Conical head is then conducive to directly squeezing into ground
In soil.
On the basis of technique scheme, this utility model can also do following improvement.
Further, described straight length is seamless steel pipe, a diameter of 38～60 millimeters of described seamless steel pipe,

Detailed description of the invention
Being described principle of the present utility model and feature below in conjunction with accompanying drawing, example is served only for solving
Release this utility model, be not intended to limit scope of the present utility model.
As shown in Fig. 1～2, one pole power ground, including the upper tube head 1 being connected as a single entity successively, straight tube
Section 2 and conical head 4, described straight length 2 is provided with helical fin 3, and described helical fin 3 is by steel band
On the outer wall of described straight length 2, helically coiling is welded, and described helical fin 3 is additionally provided with concavo-convex
Gauffer 5, described straight length 2 is welded with ground lead 6.
Described straight length 2 is seamless steel pipe, a diameter of 38～60 millimeters of described seamless steel pipe, described
The width of steel band is 20～50 millimeters.Described straight length 2 can also be copper tube.
The thickness of steel band is 0.2～1 millimeter.
Described seamless steel pipe and helical fin all have zinc coat.
This utility model making step is as follows: as a example by above-mentioned preferred material, uses diameter 38mm not
Zinc-plated seamless steel pipe；Select thick 0.2mm, the steel band of wide 30mm, and formation after suppressing by mold
Gauffer steel band；Gauffer steel band after compacting around the home and is welded in outside seamless steel pipe with spacing 40mm spiral
Surface, and ground lead is set, tube head and conical head in welding.Take again overall outer surface pickling,
The mode of galvanizing, defines a complete zinc coat at fin outer surface and outer surface of steel tube.
Body power ground of the present utility model is relatively more suitable for when construction disposably burying underground, and ensures periphery
Soil or bentonitic abundant compacting.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all
Within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
