Fire extinguishing unmanned aerial vehicle for forests and grasslands

Abstract

The invention discloses a fire extinguishing unmanned aerial vehicle for forests and grasslands, and relates to the technical field of unmanned aerial vehicles. The fire extinguishing unmanned aerial vehicle comprises a shell, a power box, a control box, a water storage tank and an intelligent control system, an upper vehicle arm and a lower vehicle arm are movably arranged in a connecting block, a power assembly is arranged in the power box, a spraying assembly is arranged in the water storage tank, the power assembly comprises a first motor, a first rotating shaft, a first bearing, a main gear, a lead screw and an auxiliary gear, and the spraying assembly comprises a spraying pipe, an electromagnetic valve, a rotating disc, a fixing ring, a pulley and a connecting rod. According to the fire extinguishing unmanned aerial vehicle for forests and grasslands, provided power is adjusted to drive the unmanned aerial vehicle to fly normally, it can be guaranteed that the unmanned aerial vehicle has enough power to support load-carrying flight, use of the unmanned aerial vehicle is facilitated, normal forest fire extinguishing is guaranteed, water flow is scattered and sprayed out, the spraying range of a fire extinguishing agent is widened, the coverage area is increased, according to the size of forest fire, the opening size of the electromagnetic valve is intelligently controlled, and accurate fire extinguishing is achieved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a fire-fighting unmanned aerial vehicle used in forests and grasslands. Background technique [0002] Forest steppe is the transition zone between deciduous broad-leaved forest and grassland in the temperate zone, that is, the ecotone zone (or ecological transition zone) between these two zones. It is not a more uniform type of vegetation, but a large mosaic of deciduous forest and meadow steppe. Forest steppe vegetation is dense and prone to fire during hot and dry seasons. Once a forest steppe fire occurs, it has devastating effects and requires firefighting. People rushed to the fire scene to carry out fire fighting and rescue operations. However, the terrain of the forest is rugged and complex, and the forest fires are fierce. It is difficult for firefighters to enter some dangerous fire places. Progress and development, UAV, as a powerful supplement to the ...

AI Technical Summary

Problems solved by technology

[0003] At present, the number of rotors of most drones on the market is too large, and the wind generated by too many rotors is relatively large. When spraying dry powder or fire extinguishing agent, it is easy to make it deviate, affecting the normal discharge of dry powder or fire extinguishing agent. The spraying of the fire extinguishing agent is carried out in a straight-down manner. There is a problem that the sprayed dry powder or the fire extinguishing agent is concentrated, making the coverage area relatively small, resulting in an unsatisfactory fire extinguishing effect, and most drones use a single rotor to provide the power of the drone. , in the case of carrying a heavy fire extinguishing agent, it cannot provide enough power

[0004] The stock of fire extinguishing agent carried by the existing UAV needs to be guaranteed. When the stock is relatively large, it cannot be guaranteed that the UAV can have enough power to drive the UAV to fly normally. When the UAV is used to extinguish small flames , environmental factors need to be considered, there is a problem that the coverage of the fire extinguishing agent sprayed by the UAV is relatively low, and the sprayed fire extinguishing agent is relatively concentrated. For this reason, we propose a fire extinguishing UAV for forest grassland
