There is SWCN composite anti-wear coating 2, the top of aluminium alloy support bar 1 is provided with the needle point 3 stacked by CNT,
The bottom of needle point 3 is merged at the top of aluminium alloy support bar 1 by negative pressure casting infiltration, and the top of needle point 3 is provided with many carbon nanometers
The point 4 that pipe is made.
Of the invention to connect sudden strain of a muscle bar, the top cross section of the aluminium alloy support bar 1 is circle, the top of aluminium alloy support bar 1
End face diameter is not less than 2mm.
Of the invention to connect sudden strain of a muscle bar, the cross section of the needle point 3 is circle.
Of the invention to connect sudden strain of a muscle bar, the point 4 is formed by 3-10 roots CNT stacking, the top seal of point 4
A diameter of 6-60nm, the top of point 4 forms pentagonal CNT sealing.
Of the invention to connect sudden strain of a muscle bar, the distance between the top of the point 4 and the bottom face of needle point 3 are 3-5mm.
Of the invention to connect sudden strain of a muscle bar, the diameter of the CNT is 2-6nm.
The sudden strain of a muscle bar that connects of the invention only elaborates to support bar, needle point and its connection, base, earthing or grounding means and support bar
Between connection, fixed form connect that sudden strain of a muscle bar is similar with common, i.e. earthing or grounding means and support bar is bolted to connection in base
On.Merged at the top of support bar using negative pressure casting infiltration the bottom of the needle point, it is ensured that the section of needle point bottom and support bar
The section at top is accurate, closely form an entirety.The tip point material for connecing sudden strain of a muscle bar is metal carbon nanotube.Needle point entirety
（Including point）3-5mm is stacked to highly by the CNT of One-dimensional Quantum material, the top of needle point is provided with many carbon nanometers
The point that pipe is made, makes pentagon appear precisely at the top of point, that is, form the sealing of CNT.The five-membered ring is sealed
Mouthful can intensified response activity, in the presence of high temperature or other materials, end is unfolded into caliber, easily infiltrates shape by metal
Into metal-base composites, can high temperature resistant, resistance thermal denaturation can be strong, make CNT and metal material perfect adaptation.It is described to connect
The support bar outer wall and connecting portion for dodging bar scribble SWCN composite anti-wear coating.Further ensure to connect and dodge bar
Durability degree and requirement for anticorrosion.The caliber scope that described CNT is selected is 2-6nm：When caliber is less than 6nm, CNT
The good One-dimensional Quantum wire of electric conductivity can be regarded as, when caliber is more than 6nm, electric conductivity rapid drawdown.Supporting bar top section
A diameter of 2-3mm at place, the support bar near apart from needle point is smaller than the support bar section remote apart from needle point.
Nanoscale needle point tip of the present invention processing technology possesses operability, and CNT is to study so far
It was found that made sharpness highest material, its sophisticated sharpness is higher, is more conducive to gathering for electric charge, guiding electric discharge energy
Power is stronger.Meanwhile, the structure of CNT is identical with the lamellar structure of graphite, and with good electric property, electrical conductivity is usual
Up to 10,000 times of copper, can be released to lightning current in counterpoises rapidly by this superconductivity.
Carbon atom takes SP2 hydridization in CNT of the present invention, makes it have high-modulus and high intensity, mechanical property
Can be good.Wherein, tensile strength is 100 times of steel, and density but only has the 1/6 of steel, and its elastic modelling quantity is suitable with diamond, about
It is 5 times of steel.The hardness of CNT is suitable with diamond, but possesses good pliability, stretches not easy to break.
Additionally, CNT has good heat transfer property, heat exchange performance alongst is very high, there is higher
Thermal conductivity, fusing point is highest in known materials.The exactly quick heat radiating capability of CNT, resulting single wall carbon is received
Mitron composite anti-wear coating realizes bigger burning resistance compared with conventional brominated flame retardant, and flammability can reduce by 35%.
The coating under equal conditions also has relatively low dry friction coefficient, and abrasion resistance properties are better than the compound painting of nickel cobalt under equal conditions
Layer, its self-lubricating patience and corrosion resistance further ensure the durability degree and requirement for anticorrosion for connecing and dodging bar.
It is of the invention connect sudden strain of a muscle bar construct when, all metal part surfaces must brushing SWCN complex abrasion-proof apply
Layer, notes the protection of coating so that support bar surface has the self-lubricating property of graphite during operation, further ensure and connect sudden strain of a muscle bar
Durability degree and requirement for anticorrosion, connect the installation of dodging lower end and be fixedly connected need to be using conventional bolt, chuck nut, fixture pressing plate
With the instrument such as spring washer, job site should ensure that the lower end of support bar and follow-up support bar be reliably connected, electric insertion.Support bar should
Firmly, perpendicularity tolerance is 3/1000 to right angle setting, and support bar is made up of conductor material, can use aluminum alloy materials, phase
It is lighter for iron and steel quality, further facilitate transport and assembled.Component of the present invention is simple, in-site installation convenient, without increasing
Plus other devices, drawing thunder performance and earial drainage aspect of performance is had outstanding performance, be conducive to strengthening lightning protection effect.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of the technology of the present invention principle is not departed from, some improvement and modification can also be made, these are improved and modification
Also should be regarded as protection scope of the present invention.
