Description

Light-duty ageing-resistant tensile optical electricity composite power transmission is tethered at cable

Technical field

The utility model is related to a kind of lighter-than-air flight device and ground installation transmission signal is tethered at cable, more particularly to a kind of The photoelectricity that communication service can be provided for dirigible or balloon etc. simultaneously and provide electric power compound is tethered at cable.

Background technology

China starts late in civilian unmanned plane market, but it is burning hot to undergo an unusual development, and is clapped at present in environmental protection, movie and television play Take the photograph, agricultural, electric inspection process, its many-sided visible figure such as express delivery industry.It is but domestic technically still to be deposited with external unmanned plane In certain gap, most obvious is exactly dynamical system and power system, the gap of whistle control system, is mainly reflected in and starts On machine and battery, signal control.In addition, in O-E Payload ability, the country also is difficult to reach external level.

By inquiry, it is contemplated that the five-year China is civilian will to be with the big field annual average compound growth rate of consumer level unmanned plane two It is maintained at more than 19%.The fields such as civilian unmanned plane future market focuses primarily upon agricultural plant protection, video display are taken photo by plane, electric inspection process, in advance The following civilian unmanned plane market scale in 10 years China of meter will be 30,000,000,000 yuan.It is expected that in addition to taking photo by plane with model plane, its future will have More application extensions, are such as combined with agricultural, and unmanned plane can monitor crop growth conditions, water requirement etc. by taking photo by plane.Therefore, The cable enterprise for the extraordinary signal transmission that the lighter-than-air flight device such as supporting unmanned plane uses brings opportunity, researches and develops a kind of novel light Ageing-resistant tensile optical electricity composite power transmission is tethered at the necessary task that cable is cable enterprise.

Utility model content

The utility model purpose is to be directed to problem above, there is provided a kind of ageing-resistant, tension, bending resistance bilge radius are small, anti-machine Tool external force is damaged, signal transmission performance power is strong, good insulation preformance light-duty ageing-resistant tensile optical electricity composite power transmission is tethered at electricity Cable.

The utility model is included by least one unit optical fiber, protection core, the cable that at least one power wire core group is formed Core；Synthetic fibers terylene lapping layer, light metal armor and environment-friendly novel TPU polymer are orderly arranged outside each in the cable core External sheath layer；In the cable core gap setting packed layer；Per share described unit optical fiber includes some fiber units respectively, if Do and the small sheath of polymer and braiding aramid layers are extruded outside described fiber unit；It is tin plating soft that the protection core includes some first Copper wire bundle strand conductor, fluoropolymer tape insulation layer is set on the outside of some the first described tin plating soft copper silk bundle strand conductors；It is per share Described power wire core includes some second tin plating soft copper silk bundle strand conductors respectively, in some the second described tin plating soft copper tow Twist parcel fluoroplastic polymer insulating barrier on the outside of conductor.

The utility model is rational in infrastructure simple, and it is easy to manufacture, conductor use by multiply soft copper silk conductor around parcel Fluoropolymer band, there is high-low temperature resistant, the function such as corrosion-resistant, wear-resisting and thickness of insulating layer is thin realizes light-duty loss of weight；It is environmentally friendly new Type TPU polymer external sheath layers, realize the performance such as ageing-resistant, weather-proof；Synthetic fibers terylene improve durable, tension, Good, the on-deformable function of elasticity, product are applied to the connection of aircraft and land equipment.
