Abstract
The utility model discloses a kind of improve down conductor, including round bar and contiguous block, described round bar one end is fixedly connected with described contiguous block, and described round bar is followed successively by circular steel, circle copper coating and circle from inside to outside and covers tin layers；Metal fixed cover is welded with described contiguous block, one end grafting of described round bar is fixed in described metal fixed cover；It is provided with connecting hole, described connecting hole is fixedly connected with breaking of contact on described contiguous block.This improvement down conductor solves the problems, such as that existing copper covers steel ground lead and is easily stolen.
Description
Technical field
This utility model is related to grounding-for-lightning device technical field and in particular to a kind of improve down conductor.
Background technology
Lightning protection generally comprise consisting of part：(1) lightning receptor device：Directly or indirectly accept the gold of thunder and lightning
Belong to bar (arrester), such as discharging rod, lighting proof strip (net), aerial earth wire and spark gap etc.；(2) earth lead (downlead)：Thunder and lightning connects
The metallic conductor that receiving apparatus are connected with grounding device；Its effect is that the lightning current on lightning receptor device is delivered to ground connection
On device, earth lead typically adopts round steel or band steel composition.(3) grounding body：Including the soil around grounding device and device or
Concrete, effect is that thunder-strike current is leaked into the earth effectively, and existing frequently-used grounding device has horizontal grounding pole, vertical ground connection
Pole, prolongation earthing pole and foundation grounding pole.
Wherein, earth lead can be divided into lightning protection downlead and down conductor, and lightning protection downlead refers to anti-positioned at eminence
Thunder connects the connecting line between lightning-proof grounding body for other metal objects dodging on device or building；The distance between with grounding body
Relatively long.Down conductor refers to one section of very short part welding out on grounding body, for lightning protection downlead phase
One section connecting.Generally it is understood that：Part more than breaking of contact is called lightning protection downlead, the part below breaking of contact
Do down conductor.
Copper covers steel ground structure due to having excellent electric conductivity and decay resistance, and generally its sectional area is only steel
Less than the 1/2 of ground connection material structure, service life is 3-6 times of steel ground structure, is the main of replacement steel ground structure
A kind of new structure.But copper covers steel ground structure outward appearance as copper it is easy to be erroneously interpreted as copper material.Particularly grounding lead
Offline, as the grounded part of exposed earth's surface, often stolen by artificial destruction.
Utility model content
The purpose of this utility model is to provide a kind of improvement down conductor, covers steel ground lead in order to solve existing copper
The problem being easily stolen.
For achieving the above object, the utility model discloses following technical scheme：
A kind of improvement down conductor, including round bar and contiguous block, described round bar one end and described contiguous block are fixed
Connect, described round bar is followed successively by circular steel, circle copper coating and circle from inside to outside and covers tin layers.
Further, described contiguous block is welded with metal fixed cover, one end grafting of described round bar is fixed on described
In metal fixed cover.
Further, described contiguous block is provided with connecting hole, described connecting hole is fixedly connected with breaking of contact.
Further, described round bar is replaced with flat steel bar, and described flat steel bar is fixedly connected with described contiguous block, described flat
Steel bar is followed successively by square bar, square copper coating and side from inside to outside and covers tin layers.
Further, it is provided with fixing hole between described flat steel bar and described contiguous block, by bolt or rivet interlacement.
Further, it is provided with weld layer between described flat steel bar and described contiguous block.
This utility model has the advantage that：
Copper covers steel outer layer and plates last layer and the close stannum of steel color, solves down conductor well as open ground
The grounded part of table, the problem often stolen by artificial destruction.

Wherein, 10, round bar, 20, flat steel bar, 2, contiguous block, 3, metal fixed cover, 4, connecting hole, 5, fixing hole, 6, weldering
Connect layer, 11, circular steel, 12, circle copper coating, 13, circle cover tin layers.21st, square bar, 22, square copper coating, 23, side cover tin layers.
Specific embodiment
Following examples are used for this utility model is described, but are not limited to scope of the present utility model.
Embodiment 1
As shown in Figure 1,3, a kind of improvement down conductor, including round bar 10 and contiguous block 2, described round bar 10 1
End is fixedly connected with described contiguous block 2, and described round bar 10 is followed successively by circular steel 11, circle copper coating 12 and circle from inside to outside and covers stannum
Layer 13.Copper covers steel outer layer and plates last layer and the close stannum of steel color, solves down conductor well as exposed earth's surface
Grounded part, the problem often stolen by artificial destruction.
Wherein, described contiguous block 2 is welded with metal fixed cover 3, one end grafting of described round bar 10 is fixed on described
In metal fixed cover 3.
Wherein, described contiguous block 2 is provided with connecting hole 4, described connecting hole 4 is fixedly connected with breaking of contact.Embodiment 2
On the basis of embodiment 1, as shown in Figure 2,4, described round bar 10 is replaced with flat steel bar 20, described flat steel bar 20
It is fixedly connected with described contiguous block 2, described flat steel bar 20 is followed successively by square bar 21, square copper coating 22 and side from inside to outside and covers tin layers
23.Copper covers steel outer layer and plates last layer and the close stannum of steel color, solves down conductor well as exposed earth's surface
Grounded part, the problem often stolen by artificial destruction.
Wherein, it is provided with fixing hole 5 between described flat steel bar 20 and described contiguous block 2, by bolt or rivet interlacement.
Wherein, it is provided with weld layer 6 between described flat steel bar 20 and described contiguous block 2.
Although, above with general explanation and specific embodiment, detailed description is made to this utility model,
On the basis of this utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
