An unmanned aerial vehicle with a self-powered function

Abstract

The invention provides an unmanned aerial vehicle with a self-powered function. The unmanned aerial vehicle comprises a lithium battery, a thermoelectric conversion device, a rotor wing motor, an amplifier circuit, a voltage stabilizing circuit and a large battery capacitor. The thermoelectric conversion device comprises a seebeck voltage output anode and a seebeck voltage output cathode, the anode is fixed on the surface of the lithium battery, and the cathode is connected with a shell; the amplifier circuit, the voltage stabilizing circuit and the large battery capacitor are connected in series between the anode and the cathode of the thermoelectric conversion device; the lithium battery is connected with a rotor motor and supplies electric energy to the rotor motor. The thermoelectric conversion device comprises a plurality of thermocouples composed of thermocouple metal arms and thermocouple gallium arsenide arms, the thermocouples are connected in series through metal, and two thermocouple electrodes are reserved to serve as the positive electrode and the negative electrode of seebeck voltage. Metal is aluminum or gold. Other devices needing power supply and carried on the unmanned aerial vehicle are connected between the positive electrode and the negative electrode of the thermoelectric conversion device in series. Heat energy generated by the lithium battery is converted into electric energy, equipment does not need to be added, and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with a self-powered function. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and self-contained program control device. From a technical point of view, it can be divided into: unmanned helicopter, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airship, unmanned parawing aircraft, etc. UAVs can be divided into military and civilian uses according to their application fields. At present, their applications in aerial photography, agricultural plant protection, surveying and mapping have greatly expanded the use of UAVs themselves. Unmanned helicopters are generally driven by batteries, and the battery loss of electric helicopters is very severe, resulting in short working hours of unmanned helicopters, and a large amount of heat energy is often generated during t...
