摘　　要：针对我国风力灭火设备不能完全适应我国森林灭火条件的问题,设计了一台引流式森林风力灭火机器人。利用Solidworks对其进行三维建模,利用Fluent对引流风管进行流体仿真,分析其第三节灭火风筒的直径D_(3)、喷嘴位置S0和收敛室的收敛角θ1对灭火性能的影响;通过ANSYS和MATLAB软件进一步分析三者交互性对灭火性能的影响,并对试制样机与6MF-32便携式风力灭火机器人进行了性能比对试验。结果表明,风筒尺寸最优解为S0=-20 mm、D_(3)=110 mm和θ1=15̊,在最优结构参数下本设计比6MF-32的灭火效率高。A drainage type forest fire fighting robot was designed for the problem that fire extinguishing equipment cannot be fully adapted to the forest fire extinguishing conditions in China.It was modeled in three dimensions by Solidworks,and the fluid simulation of the diversion duct was carried out by Fluent to analyze the influence of the diameter D_(3) of its third fire extinguishing wind cylinder,the nozzle position S0 and the convergence angleθ1 of the convergence chamber on the fire extinguishing performance;the influence of the interaction of the three on the fire extinguishing performance was further analyzed by ANSYS and MATLAB software,and performance comparison test was conducted between the prototype and the 6MF-32 portable wind-operated fire fighting robot.The results show that the optimal solution of wind cylinder size is S0=-20 mm,D_(3)=110 mm andθ1=15°,and the fire extinguishing efficiency of this design is higher compared with 6MF-32 under the optimal structure parameters,which helps forest firefighting better.
