Problems solved by technology

[0002] At present, the load and running time of multi-rotor aircraft are often limited by power supply systems such as batteries, and cannot carry operating equipment for a long time
At the same time, due to the limited energy density and heavy weight of the battery, it takes up most of the lift of the aircraft and reduces the maneuverability
[0003] Chinese patent CN201520446148 proposes a multi-rotor unmanned aerial vehicle wired power supply system, through the ground long-distance power supply (oil). The pay-out distance is greatly increased, which limits the flight range of the drone

Embodiment Construction

[0014] like figure 1 As shown, a suspension operation system based on high-voltage offline power supply includes a carrier device 1 and a drone 3. The carrier device 1 is provided with a power generation device 11 and a booster device 12. The power generation device 11 is used to provide alternating current. The boosting device 12 is used to boost the AC power and transform it into a high-voltage direct current, and the high-voltage direct current is transmitted to the UAV 3 through the transmission cable 2 . The power generating equipment 11 is connected with a boosting equipment 12, and the boosting equipment 12 transmits electric energy to the UAV through a self-shrinking reel 13 and a transmission cable 2.

[0015] In some embodiments, the carrying device 1 may be a heavy vehicle, a ship, or a large transport aircraft, a passenger plane, or a fixed building, or even a military heavy carrying device.

[0016] In some embodiments, the power generation equipment 11 provided ...

Abstract

The invention provides a suspension work system based on high-voltage offline power supply. The system comprises a carrying device and an unmanned aerial vehicle. The carrying device is provided witha power generation device and a boosting device. The power generation device is used for providing alternating current, the boosting device is used for boosting alternating current, then, the boostedalternating current is converted into high-voltage direct current, and the high-voltage direct current is transmitted to the unmanned aerial vehicle through a transmission cable. The problem that in asmall system, a long-distance transmission line limits the flying range of the unmanned aerial vehicle is solved, and the flying radius of the unmanned aerial vehicle is widened greatly.

Description

technical field [0001] The invention belongs to the high-voltage high-speed electric drive system technology, in particular to a suspension operation system based on high-voltage off-line power supply. Background technique [0002] At present, the load and running time of multi-rotor aircraft are often limited by power supply systems such as batteries, and cannot carry operating equipment for a long time. At the same time, due to the limited energy density and heavy weight of the battery, most of the lift of the aircraft is occupied, which reduces the maneuverability. [0003] Chinese patent CN201520446148 proposes a multi-rotor unmanned aerial vehicle wired power supply system, through the ground long-distance power supply (oil). The pay-out distance increases greatly, thereby limiting the flight range of the UAV. Contents of the invention [0004] The object of the present invention is to propose a suspension operation system based on high-voltage off-line power supply...
