Cable winding and unwinding device of mooring unmanned aerial vehicle and control system

Abstract

The invention provides a cable winding and unwinding device of a mooring unmanned aerial vehicle and a control system. A driving unit comprises a torque motor and a synchronous belt; a cable arrangement device consists of a two-way lead screw, a spiral pair and a guide rail; the torque motor directly drives a cable storage cylinder to wind cables, and drives a reciprocating lead screw to rotate by a synchronous belt transmission mechanism to realize reciprocating wire arrangement actions of the spiral pair; and optical cables penetrate through three sets of fixed free wheels and force sensors in sequence by a wire arrangement device, and are finally connected to the unmanned aerial vehicle through a guide mechanism. The torque motor directly drives the cable storage cylinder, so that the power consumption caused by such factors as mechanical friction in the transmission process is reduced; compared with single guide wheel in a traditional cable winding and unwinding device on the aspect of guiding and fixing the optical cables, three sets of free wheels are adopted; two sets of free wheels are mounted on the spiral pair to horizontally move along with rotation of the lead screw in an axis perpendicular manner; and the other set of free wheels are mounted on the bracket to guarantee invariable direction of feeding the optical cables into the force sensor so as to guarantee the measurement accuracy.

Description

technical field [0001] The invention relates to a cable retracting system, in particular to a cable retracting device and a control system for a tethered drone. Background technique [0002] With the development and promotion of UAV technology, the problem of its battery life has become more and more prominent. In order to solve this problem, people choose to combine traditional UAV technology with tethered platform technology to form a tethered UAV. The retractable cable device is the core of the tethered UAV technology, and the retractable effect of the cable connected to the UAV will directly affect the performance of the tethered UAV. [0003] Traditional retractable cable devices are mostly used for underwater robots, search and rescue robots, etc. Compared with tethered UAV retractable cable devices, these special retractable devices have a large retractable cable force and large structural size, and the design of the guide mechanism cannot meet the needs of unmanned ...
