Abstract
The invention discloses an anti-corrosion and anti-theft grounding electrode. The anti-corrosion and anti-theft grounding electrode comprises a driving head, grounding rods and connecting rods respectively connected with the driving head and the grounding rods. External threads are arranged at one end of the driving head and the two ends of each grounding rod respectively, and internal threads are arranged at the two ends of each connecting rod. Each grounding rod is a steel core with the surface covered with a copper layer. The end of the lowermost grounding rod is connected with a drill bit. The ratio of the outer diameter of the large end of the drill bit to the outer diameter of each grounding rod is larger than 3, and the surface of the drill bit is spiral or in the shape of a parachute tower. The thickness of each copper layer ranges from 0.3 mm to 0.8 mm, the number of the grounding rods ranges from 1 to 4, and all the grounding rods are connected through the connecting rods. After the grounding electrode is driven into the ground, the gap between the grounding rod bodies and the peripheral soil wall is filled with powdery or mushy resistance reducing agents.

Technical field
The present invention relates to electric power grounding device technical field, relate in particular to a kind of anticorrosion anti-theft type earth electrode.
Background technology
Earth electrode typically refers in the running environment of all kinds of electric power facilities, imbeds the earth so that the combination of the conductor being connected with the earth or a plurality of conductors, and it fully contacts with the earth, realizes and being connected with the earth equipotential, and power equipment and personal safety are shielded.
The first-selected condition of development earth electrode is chemical corrosion resistance and life cycle management economy.Current both economical corrosion resistant earth electrode, the elected round steel copper coating technical grounding utmost point, the Chinese patent that for example application number is 201220665016. 0 provides a kind of copper covered steel earth electrode, comprise steel point, earth rod and steel cap, earth rod two ends are equipped with external screw thread, the link of steel point and steel cap is equipped with internal thread, earth rod one end is connected with steel point, the other end is connected with steel cap, earth rod comprises steel core and is wrapped in the copper layer in steel core outside, also comprise tube connector, tube connector two ends are equipped with internal thread, between earth rod and earth rod, by tube connector, be connected.It utilizes electric conductivity and the useful life that copper layer is good, and the cheap price of steel core, and both are organically combined, and saves project cost, increases the service life.
But, this scheme is Shortcomings part also, and its copper layer processing technology still has preferred leeway on the one hand, and on the other hand, the product of copper coating technique is more costly to people's impression, easily stolen, should consider antitheft when construction.
Summary of the invention
The object of this invention is to provide a kind of anticorrosion anti-theft type earth electrode, it adopts comparatively preferred copper covered steel process program, is aided with the theft-prevention structure of being convenient to installing/dismounting, can not only be anticorrosion antitheft, can also enhanced grounding transparent performance, realize long service life, advantage that cost performance is high.
For realizing the technical scheme that object of the present invention adopts, be: a kind of anticorrosion anti-theft type earth electrode, comprise driving head, earth rod and the pitman being connected with both respectively, one end of described driving head and the two ends of described earth rod all arrange external screw thread, described earth rod is the steel core of surface coverage copper layer, described earth rod rod end connects drill bit, the large end external diameter of described drill bit is greater than earth rod external diameter, and described bit face is spirality or umbrella turriform.
The two ends of described pitman all arrange internal thread.
The large end external diameter of described drill bit is greater than 3 with the ratio of earth rod external diameter.
Described drill bit is Fine Steel Casting iron product, and bit face covers anticorrosive nano electrically-conducting paint.
Described copper layer thickness is 0.3~0.8mm.
Described earth rod is 1~4, adopts pitman to connect between each earth rod.
Between described earth rod and described drill bit, adopt heat release welding.
Described earth electrode enters behind ground, and resistance reducing agent is filled in ground connection barred body and peripheral Tu Bi space.
Described resistance reducing agent is powdery or atherosclerotic.
Beneficial effect of the present invention is embodied in:
1, anti-theft effect is obvious.
The present invention has improved the top circular cone of traditional copper coated grounded pole, manufactures special end drill bit, and when can convenient being driven underground quickly, its surperficial special shape has also strengthened extracts difficulty, has certain anti-theft feature; Between earth rod and drill bit, adopt heat release welding, connect safe and reliable, joint firmly, good stability; Pitman connects many earth rods, improves the ground connection degree of depth, can reach undergroundly below 3 meters, has both met the low stopping requirement of special occasions, has also strengthened antitheft dynamics.
2, corrosion resistance is strong.
Copper covered steel earth rod of the present invention, have copper bed thickness, degree of adhesion good, the feature such as do not peel off.Its tensile strength is large, and corrosion resistance is strong, has constant low resistance and good plasticity, and the performance that existing and copper are equal to has again steel characteristics concurrently, the employing of electroplating technology, overcome the coated method adhesion of traditional sleeve poor, easily peel off, the defect such as copper layer is easily corroded.
Through test, show, the thickness of copper plate must not be less than 0.254mm, also unsuitable excessive, otherwise will increase technology difficulty, and causes cost to raise and the wasting of resources.The present invention is restricted to 0.3~0.8mm by copper layer thickness, can meet to the full extent the demand of technique and cost.Under this thickness, the combination of copper and steel is particularly tight; If in conjunction with not tight, just can produce galvanic effect in energising situation, can there is oxidation reaction and become iron ion loss in anode metal iron, accelerate steel core and lost.
3, conduction is strong, and ground connection permeability is good.
On the one hand, the kelvin effect of electric current, makes electro-coppering earth rod identical with same equal-specification red copper bar electric conductivity; On the other hand, earth electrode enters behind ground, in the space of peripheral Tu Bi and earth electrode barred body, fills a kind of powdery or atherosclerotic resistance reducing agent, and being used in conjunction with of copper covered steel earth rod and resistance reducing agent, can increase the ground connection permeability of earth electrode greatly.
4, cost is lower, quick and easy for installation.
The fine copper earth rod that contrast adopts in traditional sense, the mode of construction of earth strip, cost significantly declines, and meanwhile, accessory is complete, it is convenient to install, and can effectively improve efficiency of construction, should be widely promoted and use.
