AI summary

A fire extinguishing system that includes an extinguishing cylinder, a plurality of mist nozzles, a plastic fire detection tube, a first hydraulic tank, a hydraulic jack, and a second hydraulic tank. When the plastic fire detection tube is exposed to fire, the system actuates the extinguishing mechanism and pressurized water is jetted out toward the fire and therefore the fire is put out.
