Jet fire extinguishing unmanned aerial vehicle system for super high-rise building

Abstract

The invention provides a jet fire extinguishing unmanned aerial vehicle system for a super high-rise building. An engine of a ground vehicle is connected with a vehicle-mounted generator through a power takeoff to generate power, and the vehicle-mounted generator is connected with a rectifier and outputs high-voltage direct currents after being rectified by the rectifier. The ground vehicle is further provided with a standby high-voltage battery pack. The high-voltage direct-current voltage of the standby high-voltage battery pack is lower than the high-voltage direct-current voltage output after the vehicle-mounted generator is rectified. The cable output ends of the vehicle-mounted generator and the standby high-voltage battery pack are connected with a high-voltage driving motor of an unmanned aerial vehicle in parallel to supply power. An output cable of the vehicle-mounted generator and the standby high-voltage battery pack is a water and electricity composite cable. A high-pressure water pipe is arranged in the center of the water and electricity composite cable, and an electric conduction cable is arranged around the water and electricity composite cable. The water and electricity composite cable is used for continuously supplying water and power to the unmanned aerial vehicle. The jet fire extinguishing unmanned aerial vehicle system has the high-rise continuous fire extinguishing and power and water supply functions, the effective load of the unmanned aerial vehicle is greatly increased, and safer and more reliable continuous power supply can be achieved; and the problems of continuous power and water supply and reliable fire extinguishing of the super high-rise building are solved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a jet fire-extinguishing unmanned aerial vehicle system for super high-rise buildings. Background technique [0002] At present, the super-high-rise fire-fighting and mooring UAV that can realize continuous water supply and power supply is taken as an example of the UAV disclosed in the publication number CN110525656A. The announcement number CN209865100U that can realize the synchronous retraction of the water supply and power supply lines of the UAV is that the UAV has a generator power supply. Once the generator fails, the UAV power supply cannot continue, resulting in a dangerous problem of crashing. Not only that, but under the existing technology, the UAV motors in the aforementioned reference documents are usually low-voltage motors, and the UAV needs a load step-down module to realize continuous power supply to the UAV motor. The step-down mod...

Problems solved by technology

[0003] The technical problem solved by the present invention is to provide a jet fire extinguishing unmanned aerial vehicle system for super high-rise buildings. The unmanned aerial vehicle is used to remove the step-down module, and the parallel high-voltage direct current is directly used to supply power to the high-voltage drive motor 8 of the unmanned aerial vehicle. The engine load is heavy and the payload is limited; the on-board generator is used to take power from the car engine to generate power, and the high-voltage DC voltage after rectification by the generator is higher than the voltage of the high-voltage backup battery pack, so that a pressure difference is formed between the two: when the generator is running normally When the drone is powered on, the high-voltage direct current of the generator supplies power to the UAV; when the engine fuel is exhausted and the generator cannot generate power, the high-voltage backup battery pack realizes seamless switching and uninterrupted power supply instantaneously; solves the problem of continuous Safer and more secure high-voltage continuous power supply, water supply and fire extinguishing
