Fuel power individual drive large-scale plant protection unmanned aerial vehicle

Abstract

The invention relates to a fuel power individual drive large-scale plant protection unmanned aerial vehicle, which consists of an airframe, an undercarriage, avionic systems, power systems, a fuel system and towed bird systems. The airframe adopts a framework-type structure and comprises a girder, a center plate, arms, pull rods and a hood; the undercarriage is positioned at the abdomen of the airframe; each power system is fixed on an engine base at the tail end of each arm; the fuel system is arranged at the center position of the airframe; a fuel tank is inserted in the girder and is fixed on a lower center plate; a fuel pipe passes through the inside of each arm to supply fuel to a corresponding engine; each avionic system comprises a flight control board, a GPS (Global Positioning System), a laser sensor, a relay, a starting motor, a DC (Direct Current) brush electronic tuner, an electric spray nozzle and the like; each towed bird system consists of a medicine chest, a water pump, a water pipe and a shower nozzle. According to a fuel power individual drive unmanned aerial vehicle scheme provided by the invention, one electric fuel injection engine directly drives one propeller, and no any mechanical transmission mechanism exists between the electric fuel injection engine and the propeller, so that the bottlenecks of a load and endurance of an existing unmanned aerial vehicle are broken through, and an application range of the unmanned aerial vehicle is expanded.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, in particular to a large-scale plant protection unmanned aerial vehicle independently driven by fuel power. Background technique [0002] Unmanned aircraft, referred to as "UAV", is a pilotless aircraft that uses radio remote control equipment or its own program to control the control device. Drones not only liberate people from flying machines, but also unleash the potential of aircraft because they are no longer limited by human physiology. [0003] According to the different aerodynamic layout methods, UAVs can be divided into unmanned fixed-wing, unmanned helicopters, unmanned multi-rotors, unmanned airships, unmanned paragliders and unmanned orthopters, of which the first three are the most common. And the most widely used. Unmanned fixed-wing flight has the highest efficiency, long battery life, and high cruising speed, but it needs a runway, cannot hover at a fixed point...

Problems solved by technology

[0009] The technical solution adopted in the present invention is: a large-scale plant protection unmanned aerial vehicle independently driven by fuel power, which is characterized in that its composition includes: a body, a landing gear, an avionics system, a power system, a fuel system and a pod system; The body consists of main beam, center plate, machine arm, pull rod and hood. The body adopts a traditional horizontal frame layout, that is, a traditional plate-clamp structure. The main beam is located in the center of the body, and the center plate is connected to the seat through the center plate. Fixed on the main beam, the center plate is divided into an upper center plate and a lower center plate, and the machine arm is fixedly connected between the upper and lower center plates through the arm tube clamp. The tie rods include horizontal tie rods and diagonal tie rods, and the diagonal tie rods are connected by rod-beam joints The main beam and the horizontal tie rod are connected to the machine arm through the arm joint. The avionics system and fuel system are evenly arranged on the upper and lower center plates, the main beam and each machine arm, which avoids the inconvenience of disassembly and replacement caused by traditional welding and riveting. , It also solves the problems of insufficient design space caused by traditional welding and riveting, and the inability to install avionics, fuel and pod systems, etc., and achieves a simple and beautiful effect
