Abstract

The invention provides a mooring cable, a mooring UAV (unmanned aerial vehicle) assembly and a mooring UAV system. The mooring cable comprises an outer sheath, a non-metal reinforcing core, a signal transmission line and a composite conductor insulating wire core, wherein the non-metal reinforcing core, the signal transmission line and the composite conductor insulating wire core are arranged in the outer sheath and extend in the length direction of the outer sheath. The signal transmission line and the composite conductor insulation wire core SZ are twisted to form a cable core, and the nonmetal reinforcing core is disposed between the inner wall of the outer sheath and the cable core. The composite conductor insulating wire core comprises an insulating layer and a composite conductor coaxially arranged inside the insulating layer, and the composite conductor is composed of a copper wire, a copper-clad aluminum wire and an aluminum alloy wire which are formed by twisting, and the copper wire and the copper-clad aluminum wire are respectively provided with a plating layer. The weight of the cable can be effectively reduced, the conductive capability of the cable can be effectivelyimproved, the service life of the cable can be effectively prolonged, and the application reliability of the mooring cable can be effectively improved.

Description

technical field [0001] The present application relates to the field of cable technology, in particular to a tethered cable, a tethered UAV component and a tethered UAV system. Background technique [0002] With the rapid development of multi-rotor drones and aerostats and other unmanned aerial vehicles, they have been widely used in transportation, transportation, entertainment, disaster relief, film and television shooting, scientific experiments and military fields. At the same time, in order to improve the endurance and application reliability of these UAV devices, tethered cables have also emerged as the times require. Connect the UAV equipment with the power supply equipment and data transceiver equipment of the ground station through the tethered cable, which can enable the UAV equipment to perform unlimited air flight and hovering operations. [0003] In the prior art, the material of the conductor in the tethered cable is generally made of aluminum alloy, which is p...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the material of the conductor in the tethered cable is generally made of aluminum alloy, which is prone to oxidation and needs to be kept at around 90°C during long-term operation, making this kind of tethered cable extremely easy to damage for high-voltage power transmission , the service life is short; and the conductor material in the tethered cable is composed of silver-plated copper wire. Due to the quality characteristics of copper, the weight of such a tethered cable is too heavy, which will cause the problem of increased load on the drone. It is not conducive to the flight of drones; in addition, the conductors in the existing tethered cables can also be made of high-conductivity material aluminum, and because the resistivity of aluminum is greater than that of copper, the conductivity of this tethered cable Poor, and because the heat resistance level of aluminum is lower than that of copper, it also limits the withstand voltage level of the conductor

That is to say, no matter what kind of tethered cable in the prior art, it is impossible to balance its cable weight, conductivity and service life, that is, there is a problem of poor application reliability.
