Abstract
The utility model discloses a lightning-proof grounding body which relates to the technical field of lightning protection. The lightning-proof grounding body comprises a non-metal grounding body and a metal electrode core which is arranged in the center of the non-metal grounding body; and the outer surface of the non-metal grounding body is provided with a groove. The lightning-proof grounding body has the beneficial effects of having lower cost than a metal grounding body under the premise of keeping enough conductive grounding performance, having larger grounding area, and ensuring good grounding effect. The utility model also utilizes gangue which serves as industrial waste, thus the environment protection requirements can be met.
Description
Technical field
The utility model relates to shocking preventing technology.
Background technology
The effect of ground connection mainly be prevent that the person from getting shocked, equipment and circuit suffers damage, fire preventing and prevent thunderbolt, prevent static damage and ensure that electric equipment normally moves.Along with the develop rapidly of electronic technology, electronic computer steps into all trades and professions of human society already.Almost be provided with different microelectronic device of complexity and computer system in the building invariably, civil buildings are no exception.As long as building is arranged, has the place of equipment all to want ground connection.Ground connection can be described as ubiquitous, so being in great demand of earth electrode.Earth resistance is the important indicator of electrical system earthing device, and this value is the smaller the better.Particularly accurate electronic instrument requires earth resistance very low (0.1 ohm～0.25 ohm), and equipment could operate as normal.
Existing lightning protection body is all cylindric.Under the constant prerequisite of area, the shape of girth minimum is circular, as columniform earth electrode, also is under the prerequisite of same volume, the shape of contact area minimum, and contact area is relevant with the lightning protection effect.Contact area is big more, and the ground connection effect is good more.
In addition, earth electrode of the prior art mostly is metal material greatly, and cost is very high.Gangue is the solid waste that discharges in coal mining process and the coal washing process.China has accumulated the about 1000Mt of gangue over the years, and still continues to discharge about 100Mt every year, not only pile up to take up an area of, and can also the spontaneous combustion contaminated air or cause fire, influence ecological environment.
The utility model content
Technical problem to be solved in the utility model is, a kind of lightning protection body that cheaply, has the good earth effect is provided.
The technical scheme that the utility model solve the technical problem employing is, the lightning protection body is characterized in that, comprises nonmetal earth electrode and is arranged on the metal pole piece of nonmetal earth electrode center, and the outer surface of described nonmetal earth electrode is provided with groove.
Described nonmetal earth electrode is that gangue particulate and graphite particulate are formed by cementitious, calculates graphite 45%-60%, cement 20%-35%, gangue 10%-20% by weight percentage.
The cross section of described nonmetal earth electrode is a cross.
Perhaps, described nonmetal earth electrode is cylindrical, and the groove of outer surface is the circular setting perpendicular to the metal pole piece.
The beneficial effects of the utility model are, under the prerequisite that keeps abundant conductive earthing performance, have than metal earth electrode advantage more cheaply, and have bigger contact area, guarantee good ground connection effect.The utility model has also utilized the gangue as trade waste, meets environmental protection requirement more.
Below in conjunction with the drawings and specific embodiments the utility model is further described.

Embodiment
Embodiment 1: referring to Fig. 1,2.
Present embodiment comprises nonmetal earth electrode 1 and is arranged on the metal pole piece 2 of nonmetal earth electrode center that the outer surface of described nonmetal earth electrode is provided with groove.
Described nonmetal earth electrode is that gangue particulate and graphite particulate are formed by cementitious, calculates graphite 45%-60%, cement 20%-35%, gangue 10%-20% by weight percentage.
Embodiment 2: referring to Fig. 3.
The cross section of present embodiment is a cross, and metal pole piece 1 is arranged on the center of nonmetal earth electrode 2.With respect to cylindrical, present embodiment has bigger contact area.
Embodiment 3: referring to Fig. 4.
The groove of present embodiment is the circular outer surface that is arranged on nonmetal earth electrode.Present embodiment has not only kept the ground connection effect, also has good stable, and when being subjected to applied external force, the cylinder that circular groove is more smooth provides bigger resistance, is difficult for breaking away from the earth because of applied external force.
