Fire fighting drone for forest grassland

Abstract

The invention discloses an unmanned aerial vehicle for fire fighting in forests and grasslands, and relates to the technical field of unmanned aerial vehicles. The invention includes a casing, a power box, a control box, a water storage tank and an intelligent control system. The internal movement of the connecting block is provided with two upper and lower parts. The arm, the power box is provided with a power component inside, the water storage tank is provided with a spray component, the power component includes a first motor, a first rotating shaft, a first bearing, a main gear, a screw rod and a secondary gear, and the spray component includes a nozzle , solenoid valve, rotating disc, fixing ring, pulley and connecting rod. The invention is a fire-fighting unmanned aerial vehicle for forest and grassland, and the power to be provided is adjusted to drive the unmanned aerial vehicle to fly normally, which can ensure that the unmanned aerial vehicle has enough power to support the load-bearing flight, facilitate the use of the unmanned aerial vehicle, and ensure the normal operation of forest fire fighting. It is carried out, so that the water flow is dispersed and sprayed out, the scope of the fire extinguishing agent is increased, and the coverage area is increased. According to the size of the forest fire, the size of the solenoid valve opening is intelligently controlled to achieve accurate fire extinguishing.

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 temperate deciduous broad-leaved forest and grassland, that is, the intercommunity intersection area (or ecological transition zone) between these two zones. It is not a relatively uniform vegetation type, but a large mosaic of deciduous forests and meadow grasslands. Forest grasslands are densely vegetated and prone to fire in hot and dry seasons. Once a forest grassland fire occurs, it has devastating effects and requires fire fighting. Personnel rushed to the fire scene to carry out fire fighting and rescue operations. However, the forest terrain was rugged and complex, and the forest fire was fierce. It was difficult for firefighters to enter some dangerous fire locations. Entering the forest and grassland to put o...

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
