Cable winding device for mooring unmanned aerial vehicle

Abstract

The invention discloses a cable winding device for a mooring unmanned aerial vehicle. The cable winding device comprises a driving mechanism, a cable winding mechanism, a reciprocating connecting rod,a sliding block and a cable winding frame; the driving mechanism is used for driving and controlling rotation of a cable winding disc; the cable winding mechanism is used for winding a cable on a wire spool located on the cable winding mechanism, the cable winding disc and the driving mechanism are coaxially arranged, and the cable winding disc is connected to the output end of the driving mechanism; the reciprocating connecting rod is connected to the cable winding disc in parallel and is connected to the output end of the driving mechanism, and a threaded groove is formed in the reciprocating connecting rod; the sliding block is arranged in the threaded groove of the reciprocating connecting rod and can move along the threaded groove; and the wire arranging frame is arranged on the reciprocating connecting rod and can do reciprocating motion along the reciprocating connecting rod under the action of the sliding block; the cable penetrates through the cable winding frame to be connected to a mooring unmanned aerial vehicle body; and the driving mechanism and the cable winding mechanism are arranged on a base together.

Description

technical field [0001] The invention belongs to the technical field of tethered unmanned aerial vehicles. In particular, the present invention relates to a cable arranging device for mooring an unmanned aerial vehicle, and particularly relates to a device for regularly winding cables by using the cooperation of a reciprocating screw rod and a slider. Background technique [0002] Tethered drones are mainly used for long-term uninterrupted aerial surveillance and emergency communications. As the carrier of optical fiber signal transmission and current conduction, the cable cannot bear large pulling force and torque. The existing cable retracting device has a simple structure, which often leads to messy winding of the cable during the cable retracting process. For example, during the rotation of the winding reel, the shape of the single layer of the cable winding is irregular, and the cross-sectional diameter is too large or too small. Such irregularly wound cables can ea...

AI Technical Summary

Problems solved by technology

Such irregularly wound cables can easily generate uncontrollable (for example, large or small) tension and / or torque, affecting the flight effect of tethered drones

In particular, when the tension or torque generated by the cable is too large, it may damage or even break the optical fiber or electrical conductor inside the cable, and there is a danger of explosion

Or, when the tension or torque generated by the cable is small, it is impossible to accurately monitor and navigate the flight of the tethered drone. It may happen that the tethered drone has landed and the cable continues to coil, which may also damage or even Pull off the optical fiber or electrical conductor inside the cable, burying the danger of bombing
