Embodiment Construction

[0028] The specific implementation manner of the present invention will be described in detail below with reference to the drawings and embodiments.

[0029] The UAV constant tension power supply system of the present invention connects the small UAV 38 through the light power supply cable 16, and provides direct power supply or charging service for the small UAV 38. In order to realize the constant tension power supply function of the small UAV 38 during flight, the system needs to realize the automatic unwinding of the power supply cable 16 when the flying height of the small UAV 38 is raised or when it is far away from the system, and the small UAV 38 lands. Or realize the automatic winding of the power supply cable 16 when flying close to the system, and at the same time ensure that the tension on the power supply cable 16 is appropriate, and ensure that the power supply cable 16 is tensioned while not affecting the flight of the small UAV 38. A specific implementation sch...

Abstract

The invention discloses a small constant-tension power supply system for an unmanned aerial vehicle. The system includes a power supply subsystem, a reel and release subsystem, a detection subsystem and a drive subsystem. The power supply subsystem includes a sliding ring and a power supply cable, one end of the power supply cable is connected with a ground power station through the sliding ring,and the other end of the system winds an outer roller and is connected with the unmanned aerial vehicle for supply power to the unmanned aerial vehicle after lead-out; the reel and release subsystem includes an inner roller, the outer roller and a torsion spring installed between the inner roller and the outer roller, cable reel and release can be achieved through rotation of the outer roller, thetorsion spring generates torque acting on the outer roller, and it is ensured that a power supply cable still keeps tension; the detection subsystem detects the angle difference between the inner roller and the outer roller, and a control signal is generated to drive a stepper motor to move. The system provides power for the unmanned aerial vehicle through a light power supply cable, and the functions of automatic reeling and releasing can be achieved according to the flying height and distance of the unmanned aerial vehicle, and the unmanned aerial vehicle can fly in air for a long time.

Description

technical field [0001] The invention relates to the field of robots and automation, in particular to a constant tension power supply system for a small unmanned aerial vehicle. Background technique [0002] Small unmanned aerial vehicles, typically represented by multi-rotor aircraft, are small in size, light in weight, easy to carry, less restricted by the site for takeoff and landing, flexible in operation, hoverable, and low in price, and can easily enter various harsh environments that are difficult for people to enter Environmental and other advantages, it has been widely used in many fields such as aerial photography, film and television shooting, regional monitoring, power inspection, environmental protection monitoring, agriculture, forestry and plant protection, aerial base stations, disaster rescue, surveying, mapping and exploration. With the development of the smart electronics industry, the application scenarios of small UAVs are becoming more and more extensive...
