N2 - Aiming at the occasions with limited water sources such as automatic inspection type fire extinguishing robots and unmanned aerial vehicles, the precise control of firefighting jets is studied, and the computational fluid dynamics (CFD) method is used to carry out the jet flow field during firefighting water cannons. Numerical simulation research to study the influence of different exit speeds and pitch angles on the fire extinguishing effect. The simulation results show that with the increase of the jet speed of the fire extinguisher robot, the pressure shape of the jet impacting the ground will not change, the effective pressure area will increase with the increase of speed, and the central area of the pressure will also slightly increase. The effective fire extinguishing area is increased and the fire extinguishing can be realized more quickly. The increase in the spray speed of the fire extinguishing robot will also make the water mist ripples sputtered by the jet denser, and the diameter of the sputtered droplets will also be reduced, and the evaporation and heat absorption effect will be better. As the pitch angle of the fire extinguishing robot increases, the shape of the impact pressure area is getting closer and closer to a circle, and the maximum pressure value is getting larger.
