Abstract
Provided is a grounding apparatus comprising a grounding body (1) connected with a lightning conductor through a wire (3). The grounding apparatus is characterized in that the grounding body (1) is a ground inserting rod by connecting a bottom segment (12) with a top segment (11), wherein the bottom segment (12) is a metallic rod with high chemical activity and the top segment (11) is a metallic rod with low chemical activity. The grounding apparatus has following advantages. Not only is a good current draining area formed, but also when large current impacts, the potential gradient of the grounding body can be effectively adjusted in order to reduce the probability of generation of reverse break of ground electric potential. The grounding body is the ground inserting rod by connecting the bottom segment with the top segment, wherein the bottom segment is a metallic rod with high chemical activity and the top segment is a metallic rod with low chemical activity. Therefore, using the characteristic of electrochemical corrosion, such structure achieves a fact that a primary battery is firstly formed by the ground inserting rod and the metallic rod with high chemical activity so that the metallic rod with high chemical activity is firstly to be corroded. Therefore, corrosion of the metallic rod with low chemical activity is effectively delayed and the service life of the grounding body is substantially prolonged. The grounding apparatus has practicality and is worth popularizing and applying.
Description
Technical field
The utility model relates to the technical field of lightning rod, specifically refers to a kind of lightning rod earthing device.
Background technology
Lightning rod has another name called lightning rod, is to protect building etc. to avoid the device that is struck by lightning.The lightning protection effect of lightning rod is that it can be guided lightning oneself into and leak into the earth by itself safely from protection thing top, and therefore, it draws the thunder performance and the earial drainage performance is vital.Ground connection is the most important link of lightening protection engineering, no matter be direct lightning strike protection or the guard technology of the electrostatic induction of thunder and lightning, electromagnetic induction and lightning surge intrusion, finally all is that lightning current is sent into the earth.The existing patent No. is that the Chinese utility model patent that the CN201220233033.7 name is called " composition metal earth electrode " has proposed a kind of structure, this utility model discloses a kind of composition metal earth electrode, earth electrode is solid earth electrode, earth electrode includes steel core and is coated on the copper layer of steel core periphery along the steel core length direction, also is coated with the zinc layer along the length direction of described copper layer; Steel core and copper layer fit tightly; Copper layer and zinc layer also fit tightly; The radial thickness of steel core is 2mm-90mm, and the radial thickness of copper layer is 0.1mm-5mm, and the radial thickness of zinc layer is 20 μ m-30mm.This utility model has been avoided the corrosion to steel, the grounding apparatus such as copper, has guaranteed the useful life of equipment.Middle copper layer has higher resistivity, and good conductance when having guaranteed grounding apparatus generation fault current, has good water conservancy diversion discharge capacity.But its shortcoming is that the copper steel adhesion is poor, can't satisfy the big-length requirement.Other is because existing the gap between two kinds of different metals, and in depth the lower galvanic effect that easily forms easily corrodes, and useful life is short, and the copper layer easily peels off.Therefore, need to do further improvement to the structure of this composition metal earth electrode.
Summary of the invention
Technical problem to be solved in the utility model be provide for above-mentioned prior art present situation a kind of have conduct electricity very well and can delay to corrode and the earthing device that increases the service life.
The utility model solves the problems of the technologies described above the technical scheme that adopts: earthing device of the present invention, include the earth electrode that is connected with lightning rod by wire, it is characterized in that: described earth electrode is to be that the low metal bar of hypomere and chemism is the grounding rod that epimere is formed by connecting by the high metal bar of chemism.
As improvement, described earth electrode is to be alloy bar or stainless steel by epimere, hypomere is the integrative-structure of zinc bar by being welded, and the resistance value of connecting portion is down to minimum, has improved the diffusing rate of electric current, guaranteed the safety of earth work, behind the heavy current impact, change in resistance is little, and acomia brittle failure is split phenomenon and occured, earthing effect is good, highly versatile.
Improve, described earth electrode is comprised of three sections metal bars, and arranges from low to high with chemism successively from top to bottom again, and by welding or being threaded togather, the metal active of gradient can effectively be alleviated the corrosion of low activity metal bar between two metal bars.
Improve, described earth electrode profile is cylinder, prism or flat cylinder again, optimizes under the different soil environments and selects.
Compared with prior art, the utility model has the advantage of: described lightning rod earthing device has good anticorrosive property and long-acting stability, since in several sections earth electrodes because of the Combination Design of the metal material of different chemical activity, particularly hypomere is set to zinc metal bar processed, epimere is the alloy bar of stainless steel or other stable materials, not only prodigiosin forms good earial drainage zone, and when heavy current impact, regulated ground bulk potential gradient effectively, reduce step voltage and touch voltage, reduce the probability of spot potential counterattack; And, this earth electrode is to be that the low metal bar of hypomere and chemism is the grounding rod that epimere is formed by connecting by the high metal bar of chemism, the design of this structure, utilize the characteristic of couple corrosion, make grounding rod at first consist of source battery to the high metal bar of chemism and corrode, effectively delayed the corrosion to the low metal bar of chemism, greatly prolonged the useful life of this earth electrode, so this earthing device is a kind of very practical device, is worthy of popularization.

Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figures 1 to 3, the lightning rod earthing device of the present embodiment, include the earth electrode 1 that is connected with lightning rod by wire 3, it is characterized in that: described earth electrode 1 is to be that the low metal bar of hypomere 12 and chemism is the grounding rod that epimere 11 is formed by connecting by the high metal bar of chemism.
Earth electrode 1 is to be alloy bar or stainless steel by epimere 11, hypomere 12 is the integrative-structure of zinc bar by being welded, perhaps formed by three sections metal bars, also can select four sections, five sections etc., and arrange from low to high with chemism successively from top to bottom, by welding or being threaded togather, specific design is inhaled the hydrogen-type corrosion degree on couple corrosion in the soil, oxygen uptake burn into and is decided between two metal bars.Several sections of earth electrode 1 by what be made of welded connection, should coat simultaneously pitch or corrosion resistant coating at the outer weldering lacquer of removing of welding, in case pole piece corrodes, is combined into by screw thread or other couplings, preferably coats anti-corrosion material.Earth electrode 1 profile is cylinder, prism or flat cylinder, the visual soil physical properties of concrete structure and becoming.During use, this earthing device is connected lightning rod by wire, and be embedded under the soil the suitable degree of depth and get final product.
