Fire extinguishing method and system capable of generating continuous vortex rings

Abstract

The invention discloses a fire extinguishing method and system capable of generating a continuous vortex ring, and the system comprises a cavity system which is internally provided with a cavity, the cavity is provided with a first opening and a second opening, and the second opening is a narrowed opening; the motion system is nested in the cavity system; the power system provides power for the motion system; and the control system provides control electric power for the power system. During working, the motion system periodically vibrates back and forth in the cavity system, and air in the cavity is pushed out of the second opening to form continuous and stable vortex ring pulses. Due to the fact that the diameter of the second opening is small, space dissipation of vibration kinetic energy of the movement system is reduced, the vibration kinetic energy of the movement system is used for generating the vortex ring in a more concentrated mode, the stability and the long-distance transmission capacity of the vortex ring are improved, and the stable and long-distance fire extinguishing effect is achieved. 本发明公开了一种产生连续涡环的灭火方法与系统，系统包括：腔体系统，其内形成腔体，腔体具有第一开口和第二开口，第二开口为收窄口；运动系统，嵌套于腔体系统中；动力系统，为运动系统提供动力；控制系统，为动力系统提供操控电力。工作时，运动系统在腔体系统内做前后周期振动，将腔体内的空气推出第二开口形成连续且稳定的涡环脉冲。由于第二开口的直径较小，减少了运动系统的振动动能的空间耗散，使运动系统的振动动能被更加集中的用于产生涡环，以此提升涡环的稳定性和远距传播能力，实现稳定远距离灭火的效果。
