The beneficial effect of the utility model: the utility model discloses characteristics such as the cable has light in weight, tensile strength is big, the external diameter is little, high voltage withstanding, resistant high low temperature, rounding, softness, convenient to use have greatly improved the ascending high of unmanned aerial vehicle, and it is wider to make unmanned aerial vehicle listen the scope.
Description
Technical field
The utility model is related to a kind of high-strength light unmanned plane can be tethered at height with cable, specifically one kind is tethered at
The unmanned plane of idle job simultaneously provides the high-strength light cable of power for it.
Background technology
With the demand continued to develop with each field of science and technology, the unmanned plane demand of different purposes is just growing day by day.It is tethered at
Multiaxis (rotor) unmanned plane, is a branch of current unmanned plane, is mainly used in long-time high-altitude and detects at a distance, aerial to stop
As long as time can reach some months.The type unmanned plane is using ground HVDC voltage-stabilizing system, by being tethered at cable to nobody
Machine conveys electric energy, and because the lift that this kind of unmanned plane rotor is provided is limited, when unmanned plane rises, the length of cable can constantly increase
Plus, deadweight is also constantly increasing, and causes the wicking height of unmanned plane to be restricted, unmanned plane system used in current industry
Testing cable is mostly, using FEP fluoroplastic insulations, the structural shape of polyurethane jacket, if can be improved by structure, to meet
Using the weight that cable is reduced on the basis of function, will can all have further to the lifting height of unmanned plane, detecting ability etc.
Lifting.
Utility model content
To overcome the defect of prior art, the purpose of this utility model is to provide a kind of high-strength light unmanned plane system
Testing cable, with lightweight, external diameter is small, stretching resistance, current-carrying capacity are big, high-low temperature resistant the features such as, the utility model is by as set about
Duan Shixian：
A kind of high-strength light unmanned plane is made up of with cable is tethered at cable core, tensile core, band and oversheath, institute
The cable core stated is constituted by two master cores and two packings are stranded, the outer wrapped one layer of band of cable core, outside band
Oversheath is extruded, described master core includes the extrusion insulating barrier outside conductor and conductor.
Further, described in two master core, the section center of circle of packing described in two are distributed in four of rhombus
On angle, and the symmetrical section circle center line connecting for being distributed in the master core described in two of packing described in two both sides；It is described
Tensile core be in flat, be symmetrically arranged at master core between packing.
Above-mentioned reasonable structural arrangement, can effectively reduce the diameter of cable, and improve pull resistance.
Further, described conductor by 19 ф 0.12mm silver-coated copper wires according to 1+6+12 structure in the same direction stranded structure
Into, and it is the stranded conductor of 0.56mm to use bunch mould to press into external diameter, reduces the outside diameter of cable so that integral material weight drops
It is low, and resistance is small, and current-carrying is big.
Further, described insulating barrier, packing and oversheath are with ethylene-tetrafluoroethylene copolymer as material, absolutely
Edge layer is wrapped on conductor by melting extrusion mode, and thickness is 0.16mm, and being tethered at FEP fluoroplastics used by cable with tradition makees exhausted
Edge layer is compared, and the thickness of insulating layer is smaller (FEP thickness of insulating layer be 0.25mm), weight it is lighter (density is 1.76g/mm3, and
FEP density is 2.2g/mm3), which decrease the weight of cable.
Further, described tensile core is that to use Du Pont's aramid fiber of 1680dtex be material, with light weight, is resisted
The characteristics of drawing property is good.
The beneficial effects of the utility model：The utility model cable has that lightweight, tensile strength is big, external diameter is small, resistance to height
Voltage (3000V), high-low temperature resistant (- 65 DEG C~200 DEG C), rounding, softness, it is easy to use the features such as, drastically increase nobody
The lifting height of machine, makes unmanned plane reconnaissance range wider.
Brief description of the drawings：
Fig. 1 is the utility model structural representation.
Specific embodiment：
In order that those skilled in the art more fully understands the technical solution of the utility model, with reference to embodiment pair
The utility model is described further：
As shown in figure 1, a kind of high-strength light unmanned plane is with being tethered at cable, by cable core, tensile core 1, band 2 and outer
Sheath 3 is constituted, and described cable core is constituted by two master cores and two packings 4 are stranded, and cable core is outer wrapped one layer
Band 2, extrudes oversheath 3 outside band 2, and described master core includes the extrusion insulating barrier 5 outside conductor 6 and conductor 6.
Further, described in two master core, the section center of circle of packing 4 described in two are distributed in four of rhombus
On angle, and the symmetrical section circle center line connecting for being distributed in the master core described in two of packing 4 described in two both sides；It is described
Tensile core 1 be in flat, be symmetrically arranged at master core between packing 4.
Used as the utility model preferred embodiment, described conductor 6 is according to 1+6 by 19 ф 0.12mm silver-coated copper wires
+ 12 structural arrangement, direction of lay is left-hand, and it is pressed using Ф 0.56mm bunch moulds, makes its conductor 6 stranded outer
Footpath is reduced to 0.56mm from 0.60mm, can so reduce Integral cable external diameter, reaches the purpose for reducing material weight, is with tradition
Tinned conductor used by testing cable is compared, and the external diameter of conductor 6 is smaller, D.C. resistance reduces (silver-colored resistivity is small), and current-carrying capacity increases.
Insulating barrier 5 uses ethylene-tetrafluoroethylene copolymer material, is wrapped on conductor by melting extrusion mode, insulate
5 thickness of layer are 0.16mm, compared with FEP fluoroplastics make insulating barrier used by tradition is tethered at cable, the smaller (FEP of the thickness of insulating barrier 5
Thickness of insulating layer is 0.25mm), weight is lighter (density is 1.76g/mm3, and FEP density is 2.2g/mm3), which decreases
The weight of cable.
