Description
Technical field
This utility model relates to technical field power ground, especially relates to a kind of earthing pole.
Background technology
Earthing pole generally refers in the environment that all kinds of electric power facilities run; embedment the earth so that the earth connect conductor or the combination of multiple conductor; it is fully contacted with the earth; realize and the earth equipotential link; mostly the earthing pole used at present that shields power equipment and personal safety is a steel pole; earthing pole top is provided with binding post; the end area of this earthing pole is smaller; when prize earthing poles such as using electric hammer is driven underground; easily train off; not only be inconvenient to operate, also potential safety hazard.
Chinese patent CN 204614974 U discloses a kind of Novel connecting earth polar, include earthing pole body, earthing pole body is provided with binding post, a parallels is fixed in the upper end of earthing pole body, lateral frame is installed in parallels, fix respectively between two ends and the earthing pole body of lateral frame and on tilted supporter, and tilted supporter, be respectively equipped with lever.This utility model can be quickly carried out earth lead and install and dismounting, but when installing this earthing pole, it is necessary first to this earthing pole is driven underground by instrument, and additionally this earthing pole is little with the earth contact area, and earth resistance is bigger.
Utility model content
In view of this, the purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of earthing pole, this earthing pole simple in construction, easy for installation, earth resistance is little, low cost.
For reaching above-mentioned purpose, this utility model by the following technical solutions:
A kind of earthing pole, including earth rod, described earth rod bottom is fixing connects into the edge of a field, described earth rod top arranges binding post, described earth rod top arranges protective cover, on described protective cover, handle is set, described earth rod bottom arranges helical blade, described earth rod is hollow-core construction, multiple oblique sets of vias is set gradually from top to bottom on described earth rod inwall, described each oblique sets of vias includes multiple oblique through hole, described oblique through hole axial line is at an acute angle with described earth rod axial line angle, in described earth rod, rod iron is set, rod iron branch is set on described rod iron, described rod iron branch bottom is inserted in described oblique through hole.
Preferably, described oblique through hole axial line and described earth rod axial line angle are 30 °～50 °.
Preferably, described oblique through hole is uniformly distributed along the circumference of described earth rod inwall.
Preferably, described handle is hinged with described protective cover.
Preferably, described protective cover is arranged accommodate the containing cavity of described handle.
The beneficial effects of the utility model are:
1, earthing pole of the present utility model, earth rod bottom arranges helical blade, by rotating the handle on protective cover, earth rod can be screwed in below ground, thus play ground connection effect, simple in construction, it is not necessary to use the equipment such as electric hammer, low cost.
2, multiple oblique sets of vias is set gradually in the middle part of earth rod on inwall from top to bottom, each oblique sets of vias includes the equally distributed oblique through hole of multiple circumference along earth rod inwall, rod iron is set in earth rod, rod iron branch is set on rod iron, rod iron branch bottom is inserted in oblique through hole, when pressing down on rod iron, rod iron branch stretches out from oblique through hole.Oblique through hole is uniformly distributed along the circumference of earth rod inwall, is equivalent to the contact area adding earthing pole with ground, can effectively reduce earth resistance, and make simple, easily construct.The most oblique through hole axial line and earth rod axial line angle are set to 30 °～50 °, the aperture of oblique through hole is more than the diameter of rod iron branch, this design may insure that when rod iron is applied pressure, and rod iron branch can stretch out from oblique through hole smoothly, reduce the purpose of earth resistance.
3, handle is hinged with protective cover, protective cover arranges the containing cavity accommodating handle, after earth rod being screwed in underground by handle, can fold in containing cavity by handle, reduces subsequent construction resistance, and structure is attractive in appearance.

Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings.
Embodiment 1
Such as Fig. 1, shown in Fig. 2 and Fig. 3, a kind of earthing pole, including earth rod 1, earth rod 1 bottom is fixing connects into the edge of a field 2, earth rod 1 top arranges binding post 3, earth rod 1 top is threaded connection protective cover 4, fixing connection handle 5 on protective cover 4, earth rod 1 bottom arranges helical blade 6, earth rod 1 is hollow-core construction, inwall in the middle part of earth rod 1 sets gradually multiple oblique sets of vias from top to bottom, the most each oblique sets of vias includes multiple oblique through hole 7, oblique through hole 7 is uniformly distributed along the circumference of earth rod 1 inwall, in the present embodiment, oblique sets of vias is 2, each oblique sets of vias has 4 oblique through holes 7；Oblique through hole 7 axial line and earth rod 1 axial line angle are 30 °～50 °, and in the present embodiment, oblique through hole 7 axial line and earth rod 1 axial line angle are 45 °；Arranging rod iron 8 in earth rod 1, rod iron 8 arranges rod iron branch 9, rod iron branch 9 bottom is inserted in oblique through hole 7, and the aperture of oblique through hole 7 is more than the diameter of rod iron branch 9.
When using earthing pole of the present utility model, first pass through the handle 5 rotated on protective cover 4, earth rod 1 is screwed in below ground, then by unclamping the screw thread between protective cover 4 and earth rod 1, protective cover 4 is taken off, then rod iron 8 is applied downward pressure, make rod iron branch 9 stretch out from oblique through hole 7, the most again protective cover 4 is arranged on earth rod 1, as shown in Figure 4.
Embodiment 2
