Oil drive variable pitch quadrotor type multifunctional fire-fighting unmanned aerial vehicle

Abstract

The invention discloses an oil drive variable pitch quadrotor type multifunctional fire-fighting unmanned aerial vehicle, relating to the field of unmanned aerial vehicles. The invention mainly aims at solving the problems that a conventional fire fighting truck is large in fire fighting limitations and the like. The unmanned aerial vehicle comprises a cabin, an undercarriage and an airbag, wherein a fuel tank is arranged in a fuel storage bin; engine arms are arranged outside the cabin; the outer ends of the engine arms are connected with rotor mechanisms; the airbag is arranged at the bottom of an engine of the rotor mechanisms; radiators are arranged on the tops of the engine arms; an power output shaft of each engine is connected with a centrifugal clutch in a reduction box; a driven gear on a main shaft is meshed with a driving gear on the centrifugal clutch; a variable pitch disc is arranged on the main shaft in a sleeving manner; rotor heads are fixed on the main shaft and are connected with the rotors in a clamping mode; the rotors are connected with one another in the clamping mode; a rocker arm of a servo rudder is connected with a connecting rod; the connecting rod is connected with a variable pitch disc shifting fork; a fixing seat is connected with the variable pitch disc shifting fork by virtue of a swing connecting rod; the variable pitch disc shifting fork is connected to the variable pitch disc; a screw pitch is arranged at the horizontal axis of the variable pitch disc and the rear end of a rotor clamp pull rod in the sleeving manner; and the rotor clamp pull rod is fixed on a rotor clamp. The unmanned aerial vehicle has the advantage of being not subjected to space limitation.

Description

Technical field: [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a fire-fighting unmanned aerial vehicle. Background technique: [0002] At present, when a fire breaks out, fire trucks are dispatched to fight the fire, but the limitations of fire trucks are very large. For example, if a fire breaks out in a high-rise building, the height of the ladder and fire water cannon spraying water is limited, and there will be situations where it is impossible to rescue and cause major property damage. Loss and casualties, if the firefighters enter the building to rescue people or put out the fire, it will endanger the life safety of the firefighters, and the rescue speed is slow in addition. Another example is the old urban areas of some cities, where the lanes are narrow and the traffic is jammed. When a fire breaks out, fire trucks often cannot get in and cannot arrive at the fire scene in time. Invention content: [0003] The technical pr...
