Embodiment Construction

[0019] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 with 2 As shown, the dual-channel power supply system for tethered UAV 10 of the present invention includes a ground power supply device 100 and a power module 200 carried by the tethered UAV 10, and the ground power supply device 100 and the power module 200 are electrically connected through a cable 20 together. The cable is retracted and unwrapped by the cable retractor 300 . Wherein, the ground power supply device 100 includes an alternating current generating device 101 , a main direct current path 102 and a secondary direct current path 103 .

[0021] The alternating current generating device 101 may be a generator for generating alternating current. The power of the generator can be 0-50KW, and the output AC voltage can be 200V-400V. In a specific embodiment, the generator has a power of 12KW and o...

Abstract

The invention relates to a dual-channel power supply system for tethered drones, which includes a ground power supply device and a power module mounted on the tethered drone. The ground power supply device and the power module are electrically connected together through cables, and the cables pass through The cable is retracted and placed, and the ground power supply device includes: an AC power generation device; a main DC path, which includes an AC-DC power conversion device, and the AC power generated by the AC power generation device is converted into a first current value with a first current value through the main DC path. a direct current; and a secondary direct current path connected in parallel with the main direct current path, comprising a charger and a storage battery pack, through which the alternating current generated by the alternating current generating device is converted into a second direct current having a second current value, para. Both a direct current and a second direct current are delivered to the power module via the cable. The invention effectively solves the problem of long-time power supply of the tethered drone, and greatly improves the flight or working time of the tethered drone.

Description

technical field [0001] The invention relates to the field of aircraft. More specifically, the present invention relates to a dual-path power supply system for tethered drones. Background technique [0002] Tethered UAV is a kind of UAV that is developing rapidly nowadays. Because the flight and control of tethered drones require high load voltage and high current, but most tethered drones are not equipped with power supply units themselves, or the power supply of their power supply units is very small, therefore, it cannot guarantee a long time. flight time. Contents of the invention [0003] In order to solve the power supply problem of the tethered drone, the present invention provides a dual-channel power supply system for the tethered drone, which includes a ground power supply device and a power module mounted on the tethered drone. The ground power supply device and the power supply module are connected together through a cable, and the cable is retracted and retr...
