Abstract
The utility model relates to an inside vibrating device of tunnel junction inspection pipeline liquid, including basement, metal electrode, two metal electrode seal inside the basement, and two metal electrode tops are relative, and the distance between the top is 0.01nm -100nm, and two metal electrode tail ends are equipped with outer guide line, and the basement is glued and is sticked on the inside pipe wall of pipeline. The utility model discloses a device is when having liquid flow management way, and liquid is inside must to have the existence of impact, vibration because of each cross -section velocity of flow differs, and these signals cause that the distance between the inside metal electrode of tunnel junction foil gage changes can pass to the tunnel junction foil gage through the pipeline on, and the tunnel current that produces so also changes thereupon, vibrates water impact through the collection tunnel current and expresses.
Description
Technical field
The utility model relates to a kind of tunnel junction inspection pipeline liquid internal vibrating device.
Background technology
The tunnel effect in quantum mechanics is utilized to develop first scanning tunnel microscope (STM) in the world from nineteen eighty-two International Business Machine Corporation (IBM) Zurich laboratory doctor GerdBinnig and doctor HeinricnRohrer, make the mankind first time can observe single atom in real time in the ordered state of material surface and the physicochemical property relevant with surface electronic behavior, the development not being only nanometer technology provides to be observed and experimental tool forcefully, and directly facilitating the fast development of nanosecond science and technology, its inventor was awarded Nobel Prize in physics in 1986.
The basic principle of work of STM is the tunnel effect in quantum theory, and carry out the distance between exploratory probe and sample by the tunnelling current between probe tip and sample surfaces, resolution reaches 0.01nm, can tell single atom.
Although the method resolution coming detecting distance or displacement with tunnelling current is very high, but, adopt instrument and equipment (comprising scanning tunnel microscope) complex structure in this way at present, special messenger is had to operate, to repeatedly calibrate during use, expensive, use occasion or application are very limited.
Utility model content
The purpose of this utility model is exactly for above-mentioned prior art Problems existing, provides a kind of tunnel junction to check pipeline liquid internal vibrating device.
Above-mentioned purpose is achieved through the following technical solutions: a kind of tunnel junction inspection pipeline liquid internal vibrating device, comprise substrate, metal electrode, two metal electrodes are sealed in base internal, two metal electrode tops are relative, distance between top is 0.01nm-100nm, two metal electrode tail ends are provided with outer guide line, and substrate is sticky on described pipe interior tube wall.
Described metal electrode top is needlepoint form.
The material of described metal electrode is platinum, tungsten, iridium or the alloy material for platinum, tungsten, iridium.
Described substrate a kind ofly produces corresponding vibrations when liquid flow and the organic material substrate of corresponding deformation occurs.
Described upper surface of substrate is smooth, and lower surface is concavo-convex is convenient to stick sticky with pipeline.
The utility model is rational in infrastructure simply, the manufacturing is easy, and result of use is good.Pass through the utility model, comprise a substrate, base internal encapsulates two metal electrodes, two metal electrode tops are needlepoint form, material is platinum, tungsten, iridium or its potpourri, two metal electrode tops are relative, distance is 0.01nm-100nm, and substrate and metal electrode form tunnel junction foil gauge jointly; One segment pipe above-mentioned tunnel junction foil gauge component is sticky on pipe interior tube wall.
The technical problems to be solved in the utility model is the condition building tunnel effect realization, by the surface of tunnel junction strain gauge adhesion in common pipe, when in pipeline during liquid flow, because the flow velocity in each cross section of current has difference a little, will inevitably exist along with vibration, this vibration can be gone down by pipeline rectilinear propagation, equally, vibration also can make pipeline produce small deformation, now, just the distance be pasted onto between tunnel junction foil gauge two metal electrode on duct wall can be caused to change, the tunnel current so produced also can change thereupon, by gather tunnel current change number just can go out the size of pipe interior liquid vibration by qualitative scalar.
When two just do not contact at point blank metal electrode, just have the generation of tunnel current between two electrodes, and tunnel current is adjusted the distance very responsive, carry out tracer liquid internal vibration situation by tunnel current.
The device of tunnel junction of the present utility model inspection pipeline liquid internal vibration just can be applied in some pipelines of constructing and regularly survey inspection, can change the size of liquid flow in time, the loss preventing from pipeline from bearing excessive flow velocity causing some unnecessary.
The basic principle of work of device of the inspection pipeline internal liquid vibration designed in the utility model is the tunnel effect in quantum theory, carrys out by the tunnelling current between two metal probe needle points the device that the size of liquid vibration is weighed in perception.Tunnelling current is adjusted the distance very responsive, and the change of distance can because the sound wave in the external world, vibrations be namely caused by impact, and the tunnel current that distance change 1 Ethylmercurichlorendimide brings is the variation relation of 10 times.In view of this, be necessary very much it is also practicable in the apparatus design that tunnel effect is incorporated into for tracer liquid internal vibration by we.
Whole world research and apply in nanosecond science and technology is worth inestimable, and the present invention realizes scale liquid internal vibration condition monitoring, will bring larger economic benefit and social benefit in research in nanotechnology.
Accompanying drawing explanation
Fig. 1 is the structure intention of a kind of tunnel junction inspection of the utility model pipeline liquid internal vibrating device.
In figure: 1 substrate, 2 metal electrodes, 3 pipelines.
Embodiment
Illustrate below in conjunction with accompanying drawing and accompanying drawing and the utility model is described in further detail.
Fig. 1 describes the apparatus structure of the present embodiment, comprise a substrate 1, at substrate 1 enclosed inside two metal electrodes 2, the material of metal electrode is platinum, tungsten, iridium or the alloy material for platinum, tungsten, iridium, two metal electrode tops are relative, distance is 0.01nm-100nm, and substrate 1 and metal electrode 2 form tunnel junction foil gauge jointly; Be sticky in by tunnel junction foil gauge in segment pipe 3 inner pipe wall, the structure of overall composition uses as tunnel junction inspection pipeline liquid internal vibrating device.
Device of the present utility model is when there being liquid passes through conduit 3, liquid internal must have the existence of shock and vibration because each cross sectional flow rate differs, these signals can pass on tunnel junction foil gauge by pipeline 3, the distance between tunnel junction foil gauge interior metal electrode 2 is caused to change, the tunnel current so produced also changes thereupon, represents water impact vibration by gathering tunnel current.
