Abstract
The utility model discloses a grounding leading-out device, which belongs to the technical field of grounding equipment. The present grounding leading-out device has the defects that the metal at the lead-out section is rapid to be corroded, water cannot be prevented from flowing on the ground surface along the gap, and the capacity for controlling the stray current cannot be realized, and the like. The grounding leading out device comprises a copper bar inner core and a zinc-cladding steel pipe which is used as an external bushing, wherein the copper bar inner core is installed inside the zinc-cladding steel pipe to form a clearance fit, the copper inner core is fixedly connected with the zinc-cladding steel pipe through a fixed ring, composite resin is filled in a gap between the zinc-cladding steel pipe and the copper bar inner core, and a water stop ring is sleeved on the zinc-cladding steel pipe. Due to adoption of the grounding leading-out device, the anti-corrosion performance of the grounding leading-out section is improved, the underground water can be effectively prevented from overflowing along the wall of the grounding device, the stray current can be effectively prevented, and the mechanical property, water resistance and heat resistance of the grounding device are improved.
Description
Technical field
The utility model belongs to ground connection equipment technology field, and is especially relevant with a kind of ground connection ejector.
Background technology
At present, general grounding system is drawn earth connection or is utilized anti-corrosion pipeline to draw earth connection etc. from shallow surface soil, structure base plate usually, above-mentioned ground connection is drawn in the measure, at first, because the section of drawing water conservancy diversion metal medium directly contacts with surrounding soil or water environment, cause the corrosion of metals of the ground connection section of drawing very fast, can not reach long-term safety effective grounding purpose.Secondly, ground outlet is subjected to extraneous elemental pulling (wind-force, surface soil vibrations etc.) or people and animals destroy, and causes existing between ground connection section of drawing and surrounding soil the gap, and then underground water can flow in the face of land along this gap, influences ground surface environment.Once more, lead-out wire directly contacts with ground surface environment, does not possess the ability of control stray electrical current.
The utility model content
The utility model is very fast at the section of the drawing corrosion of metals that above-mentioned prior art exists, can not block water flow in the face of land along the gap, do not possess the deficiency such as ability of control stray electrical current yet and provide a kind of and efficiently block water, anticorrosion, also can prevent the ground connection ejector of stray electrical current.For this reason, the utility model is by the following technical solutions:
A kind of ground connection ejector, comprise the copper bar inner core, it is characterized in that: described ground connection ejector comprises that also the zinc as external sleeve pipe covers steel pipe, described copper bar inner core is threaded onto zinc and covers formation matched in clearance in the steel pipe, copper bar inner core and zinc cover between the steel pipe and are connected and fixed by retainer ring, compound resin is filled in the gap that zinc covers between steel pipe and the copper bar inner core, and zinc covers suit seal ring on the steel pipe.
As to technique scheme further replenish and perfect, the utility model also comprises following supplementary technology scheme:
Described seal ring edge projection straight up.
Described seal ring can be set at 2, is set with the trisection point place of covering the steel pipe body in zinc.
Described seal ring also can be set at 1, is set in the midpoint that zinc covers the steel pipe body.
It is 15～20cm that described zinc covers outer diameter of steel pipes, and length is 150～200cm.
Described copper bar inner core can replace with the copper covered steel inner core.
Use the utility model can reach following beneficial effect:
1, adopts the inner core permeable medium of copper bar (copper covered steel), improved the antiseptic property of ground connection ejector as earthing device.
2, adopt the zinc anode aseptic technic; inner core is placed in zinc to be covered in the steel pipe; and fill insulated composite resin in the gap that inner core and zinc cover between the steel pipe; irony matrix equipment in the face of land and the thin solum has been played protective effect; for the inner core permeable medium provides the effect of secondary anti-corrosion protection, and can effectively prevent stray electrical current.
3, seal ring edge projection is designed to straight up, can effectively stop underground water along earthing device wall overflow, has also improved the mechanical property of earthing device.
