Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.Hereinafter implement
Example is used for illustrating the present invention, but is not limited to the scope of the present invention.
As it is shown in figure 1, one connects sudden strain of a muscle bar, including aluminium alloy support bar 1, the outer wall of described aluminium alloy support bar 1 is brushed
SWCN composite anti-wear coating 2, the top of aluminium alloy support bar 1 is had to be provided with by the needle point 3 of CNT stacking,
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.
The present invention connects sudden strain of a muscle bar, and the top cross section of described aluminium alloy support bar 1 is circular, the top of aluminium alloy support bar 1
End face diameter is not less than 2mm.
The present invention connects sudden strain of a muscle bar, and the cross section of described needle point 3 is circular.
The present invention connects sudden strain of a muscle bar, and described point 4 is formed by 3-10 root CNT stacking, the top seal of point 4
A diameter of 6-60nm, point 4 top forms the sealing of pentagonal CNT.
The present invention connects sudden strain of a muscle bar, and the distance between top and the bottom face of needle point 3 of described point 4 is 3-5mm.
The present invention connects sudden strain of a muscle bar, and the diameter of described CNT is 2-6nm.
Support bar, needle point and connection thereof are only elaborated by the sudden strain of a muscle bar that connects of the present invention, base, grounding device and support bar
Between connection, fixed form with common to connect sudden strain of a muscle bar similar, i.e. grounding device and support bar is bolted to connection in base
On.The bottom of described needle point utilizes negative pressure casting infiltration to merge at the top of support bar, it is ensured that the cross section bottom needle point and support bar
The cross section at top forms an entirety precisely, closely.The described tip point material connecing sudden strain of a muscle bar is metal carbon nanotube.Needle point is overall
(including point) is stacked to 3-5mm height by the CNT of One-dimensional Quantum material, and 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, i.e. forms the sealing of CNT.This five-membered ring seals
Mouthful can intensified response activity, under the effect of high temperature or other materials, end is unfolded into caliber, is easily infiltrated shape by metal
Become metal-base composites, can high temperature resistant, opposing thermal denaturation can be strong, make CNT and metal material perfect adaptation.Described connect
The support bar outer wall and the connecting portion that dodge bar all 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 One-dimensional Quantum wire that electric conductivity is good can be regarded as, when caliber is more than 6nm, electric conductivity rapid drawdown.Supporting bar top cross section
A diameter of 2-3mm at place, the support bar cross section more remote than distance needle point apart from the support bar that needle point is near is little.
Nanoscale needle point tip of the present invention processing technique possesses operability, and CNT is to study up to now
The highest material of made sharpness found, the sharpness at its tip is the highest, is more conducive to gathering of electric charge, guides electric discharge energy
Power is the strongest.Meanwhile, the structure of CNT is identical with the lamellar structure of graphite, has good electric property, and electrical conductivity is usual
Up to 10,000 times of copper, lightning current can be released in counterpoises rapidly by this superconductivity.
In CNT of the present invention, SP2 hydridization taked by carbon atom so that it is has 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
For steel 5 times.The hardness of CNT is suitable with diamond, but has good pliability, stretches not easy fracture.
Additionally, CNT has good heat transfer property, heat exchange performance alongst is the highest, has higher
Thermal conductivity, fusing point is the highest in known materials.The quick heat radiating capability of CNT just, consequent single wall carbon is received
Mitron composite anti-wear coating is compared with conventional brominated flame retardant, it is achieved that bigger burning resistance, and flammability can reduce by 35%.
This coating the most also has relatively low dry friction coefficient, and abrasion resistance properties is better than the compound painting of the nickel cobalt under equal conditions
Layer, its self-lubricating patience and corrosion resistance further ensure and connect durability degree and the requirement for anticorrosion dodging bar.
When connecing sudden strain of a muscle bar construction of the present invention, all metal part surfaces must be coated with by brushing SWCN complex abrasion-proof
Layer, notes the protection of coating so that support bar surface has the self-lubricating property of graphite, further ensures and connect sudden strain of a muscle bar during operation
Durability degree and requirement for anticorrosion, connect and dodge the installation of lower end and fixing connection need to use the bolt of routine, chuck nut, fixture pressing plate
With the instruments such as spring washer, job site should ensure that the lower end of support bar and follow-up support bar be reliably connected, the most through.Support bar should
Right angle setting is firm, and perpendicularity tolerance is 3/1000, and support bar is that conductor material is made, and can use aluminum alloy materials, phase
Lighter for ferrum and steel quality, further facilitate transport and assembled.Component of the present invention is simple, in-site installation convenient, it is not necessary to increase
Add other device, 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 Yuan, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and modification, these improve and modification
Also should be regarded as protection scope of the present invention.
