摘要： 风力灭火机作为扑灭森林火灾的常用消防设备，由于采用离心风机，存在出口风速小、射流距离短等问题，轴流风机可以在一定程度上克服离心风机带来的难题。本文采用轴流风机研究发现，叶根安装角和角度差的适当增大有助于提高风机的出口风速和射流距离。通过优化所得叶根安装角为38.94°，叶顶安装角为35.7°时，轴流风机的气动性能最佳，出口风速和射流距离分别提升4.65%和15.6%，为轴流式风力灭火机的研发使用提供依据。

Abstract: Abstract: As common by used fire-fighting equipment for forest fire fighting, wind-driven fire extinguisher often has some problems, such as low outlet wind speed, short jet distance and so on, due to the use of the centrifugal fan. The axial-flow fan can overcome the difficulties of centrifugal fan to a certain extent. In this paper, the axial flow fan is used. It is found that the appropriate change of blade root angle and blade top angle is helpful to improve the outlet wind speed and jet distance of the fan. After the fan is optimized by deep learning, when the blade root angle is 38.9° and the blade top angle is 35.7°, the outlet wind speed and jet distance are increased by 4.65% and 15.6%, respectively. It can improve the basis for the research and development of axial-flow wind fire extinguisher.
