Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As depicted in figs. 1 and 2, the embodiment of the present invention is to provide that one conducts electricity very well, easy for installation, the good electric power grounding device of theftproof performance, and the electric power grounding device of the embodiment of the present invention, comprising: ground connection guide pillar 1 and helical blade 2; Described ground connection guide pillar 1 is hollow circular-tube, and described helical blade 2 is wound around and is fixed on the lateral wall of described hollow circular-tube 1; Described helical blade 2 exterior contour is cylindrical, and the lateral surface of described helical blade 2 is positioned on described columniform side, and the axes coincide of the axis of described helical blade 2 and described ground connection guide pillar 1; As Fig. 2, the sidewall of described ground connection guide pillar 1 is provided with multiple suction hole 15.
Generally, the top of described ground connection guide pillar 1 is provided with top cover 10; In practical application, described top cover 10 is provided with multiple bolt, is bolted on described ground connection guide pillar 1 described in described top cover 10 passes through.
The embodiment of the present invention in use, need ground connection guide pillar to imbed or screw in soil, thus ground connection guide pillar and soil are combined closely, play the effect of conduction, the helical blade that it is wound around increases the contact area of earthing device and soil, improves conductive capability; Meanwhile, helical blade can be installed by the mode screwing in soil, and is difficult to directly be taken out by conventional means, substantially increases theftproof performance.
In addition, the multiple suction holes arranged, ensure that the soil environment of earth electrode inside in ground connection guide pillar is consistent with external environment condition, avoid the problem of the inner soil moisture of ground connection guide pillar and the excessive impedance instability caused of ambient humidity difference, so not only greatly improve the electric conductivity that ground connection guide pillar contacts with soil; Meanwhile, when suction hole makes ground connection guide pillar screw in soil, inside and outside ground pressure is more balanced, and in the process of screw-in, the soil of inside and outside can enter in ground connection guide pillar fully, to prevent in installation process remaining pressure-air in ground connection guide pillar to affect installation.Need to illustrate time, actual use, the top of ground connection guide pillar is provided with top cover, as do not arranged suction hole, is then easy to cause ground connection guide pillar inner air to compress, makes whole guide pillar be difficult to squeeze in soil, especially when guide pillar diameter is excessive.
Further, the distance between described helical blade 2 inner side edge to outer side edges is L, and the diameter of described ground connection guide pillar is D, then 1/2D≤L≤D.Under these circumstances, can make helical blade 2 fully and soil contact, not only can increase substantially the contact performance with soil, also substantially increase theftproof performance.
On the basis of above-described embodiment, as Fig. 3, in another embodiment of the present invention, can also comprise: ripping bar 2 and straight-bar 3; Described ripping bar 3 is V-arrangement bendable structure; The bottom of this V-arrangement is used for and the soil of ground connection guide pillar periphery contacts, using as fulcrum force; Generally, the bending part of described ripping bar 3 is provided with arc-shaped convex.Described top cover 10 is provided with traction column 11; One end of described ripping bar 3 and the top of described traction column 11 are hinged, and the other end of described ripping bar 3 is fixedly connected with described straight-bar 4.
One end of ripping bar 3 is plug 30, plug 30 for closely sheathed live one end of straight-bar 4.Straight-bar 4 for extending the length of ripping bar 3 side, thus plays the effect reducing moment, and handled easily personnel are laborsaving.
Because the contact area of the electric power grounding device of the embodiment of the present invention and soil is large, when removing, be difficult to extract.And when adopting ripping bar, traction column and the structure of straight-bar, only whole ground connection guide pillar upwards need be extracted the pitch of a helical blade, it is the effect due to helical blade, when being pulled out a pitch M, soil around helical blade will be taken out of, thus whole earthing device can be made to be removed easily.Doing so avoids the defect that earthing device is difficult to take out.
The embodiment of the present invention is when needs are removed, top cover 10 and traction column 11, ripping bar 2 and straight-bar 3 can be installed on top, so just can by pressing down the top of straight-bar 4, to move up a pitch M to make ground connection guide pillar 1 easily, manually whole earthing device can be taken out, greatly facilitate removing of earthing device.So the present invention is very applicable to building of temporary earthing device, installs and remove all very convenient, and there is excellent theftproof performance.
The electric power grounding device of the present embodiment can also comprise: for the backing plate 5 contacted with the bending part of described ripping bar; Described backing plate 5 is steel backing plate.Backing plate 5 greatly reduces ripping bar 3 bending part to the pressure of soil, can provide more firm on-deformable fulcrum environment for ripping bar.
On above-described embodiment basis, further, the bending angle of described ripping bar is a, 105 degree≤a≤135 degree; Be preferably 115 degree≤a≤118 degree.Under such angle, meet ergonomics most, easy to operate and laborsaving.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
