System for fire extinguishing

A fire extinguishing system, the fire extinguishing system comprising:

• an extinguish cylinder comprising a top port, a top section of the extinguish cylinder filled with a pressurized gas, a bottom section of the extinguish cylinder filled with pressurized water, the top port in fluid communication with the bottom section of the extinguish cylinder through a siphon tube;
• a plurality of mist nozzles, the plurality of mist nozzles connected to the top port of the extinguish cylinder through a first tube and, first ball valve, and a second ball valve, the first ball valve and the second ball valve configured to:
• prevent fluid communication between the bottom section of the extinguish cylinder and the plurality of mist nozzles responsive to the first ball valve and the second ball valve being closed;
• and
• provide fluid communication between the bottom section of the extinguish cylinder and the plurality of mist nozzles responsive to the first ball valve and the second ball valve being open:
• a plastic fire detection tube filled with a pressurization agent, the pressurization agent comprising nitrogen, the plastic fire detection tube configured to be ruptured responsive to the plastic fire detection tube being exposed to a fire, a hole being formed on the plastic fire detection tube responsive to the plastic fire detection tube being ruptured, the pressurization agent configured to jet out from the plastic fire detection tube and through the hole responsive to the plastic fire detection tube being ruptured;
• a first hydraulic tank, a top section of the first hydraulic tank in fluid communication with the plastic fire detection tube, the first hydraulic tank containing a first amount of a hydraulic oil at a bottom section of the first hydraulic tank;
• a hydraulic jack comprising a cylinder and a piston, the piston disposed slidably inside the cylinder and along a first axis, a bottom section of the cylinder in fluid communication with the bottom section of the first hydraulic tank, a first end of the piston connected to the first ball valve and the second ball valve, the piston configured to open the first ball valve and the second ball valve responsive to the piston moving along the first axis and in a first direction;
• a second hydraulic tank, the first hydraulic tank and the second hydraulic tank attached to each other through a plate, the plate placed between the first hydraulic tank and the second hydraulic tank, the plate comprising a small hole on the plate, the small hole configured to provide fluid communication between the first hydraulic tank and the second hydraulic tank with a low flow rate, the second hydraulic tank containing a second amount of the hydraulic oil at a bottom section of the second hydraulic tank, the bottom section of the second hydraulic tank in fluid communication with a top section of the cylinder;
• a first connecting rod, the first connecting rod interconnected between the first end of the piston and the first ball valve, responsive to movement of the piston along the first axis and in the first direction, the first connecting rod rotating in a first rotational direction, responsive to rotation of the first connecting rod in the first rotational direction, the first ball valve being opened, responsive to movement of the piston along the first axis and in a second direction, the first connecting rod rotating in a second rotational direction, responsive to rotation of the first connecting rod in the second rotational direction, the first ball valve being closed;
• a second connecting rod, the second connecting rod interconnected between the first end of the piston and the second ball valve, responsive to movement of the piston along the first axis and in the first direction, the second connecting rod rotating in the first rotational direction, responsive to rotation of the second connecting rod in the first rotational direction, the second ball valve being opened, responsive to movement of the piston along the first axis and in the second direction, the second connecting rod rotating in the second rotational direction, responsive to rotation of the second connecting rod in the second rotational direction, the second ball valve being closed;
• a third ball valve placed between the bottom section of the cylinder and the bottom section of the first hydraulic tank, responsive to the third ball valve being open, flow communication being provided between the bottom section of the cylinder and the bottom section of the first hydraulic tank, responsive to the third ball valve being closed, flow communication being prevented between the bottom section of the cylinder and the bottom section of the first hydraulic tank;
• a check valve placed between the bottom section of the cylinder and the bottom section of the first hydraulic tank and in parallel with the third ball valve;
• and
• a filter placed between the top port of the extinguish cylinder and the plurality of mist nozzles, the filter configured to prevent entering small particles to the plurality of mist nozzles;
• wherein responsive to the plastic fire detection tube being exposed to the fire:
• a pressure inside the first hydraulic tank becomes low due to the pressurization agent jetting out from the plastic fire detection tube and through the hole;
• the piston moves along the first axis and in the first direction due to a pressure difference between the first hydraulic tank and the second hydraulic tank;
• the first ball valve and the second ball valve are opened due to the piston moving along the first axis and in the first direction;
• the pressurized water flows from the bottom section of the extinguish cylinder toward the plurality of mist nozzles due to a pressure of the pressurized gas;
• and
• the pressurized water is jetted out from the plurality of mist nozzles toward the fire.
