Problem Statement

  • The prior art fire fighting method involves the fire fighters to manually put out the fire from a certain distance.
  • Said prior art methods are ineffective in controlling the spreading of fire under such circumstances.
  • To extinguish the fire quick & effectively, there is a requirement for the tip of the conventional fire fighting hose to be in close proximity to the origin of fire to effectively dispense the extinguisher at the site of the fire.
  • Further said fire fighter robots lack the sense of discretion that human posses & remotely operated system have to carry a lot of system.
  • Hence there is a need to address the issues.

Technology

  • Present invention describes a firefighting system having a remotely steerable nozzle.
  • Said system comprising:
  • a reservoir having pressurized liquid to be dispensed therefrom;
  • a hose assembly configured to dispense the liquid from the reservoir to a remotely located fire site.
  • Further, the hose assembly comprises a hose, a connector, a hydraulic elevation line including two or more steering nozzle lines.
  • The hose is having a first & a second end, the first end attached to the reservoir & the second end attached to a hose tip having a nozzle.
  • a connector is configured to detachably connect the second end to the hose tip.
  • The hydraulic elevation line running through the interior of the hose & is connected to a conduit.
  • Further two or more steering nozzle lines are connected to one or more half-steering conduits.
  • The operation of claimed device is illustrated in the figure.

Key Features / Value Proposition

Technical Perspective:

Fire-Fighting Materials: 

  • The system has designed to operate using any material or fluid configured to put out a fire, examples of fluid could be water, or in some cases gas-generating substances such as sodium bicarbonate, dissolved carbon-di-oxide, etc.
  • Further firefighting material may be solid powder such as of monoammonium phosphate, sodium bicarbonate, potassium bicarbonate or other material.

Nozzle Performance:

  • The remote steerable hose is affixed with a thermal camera that provides signal to a control console located at the liquid reservoir.
  • The Hose tip has a flat or tapered nozzle wherein the nozzle is configured to splash water in all directions equally.
  • The Nozzle is configured to direct a jet of liquid at the vane, wherein the wheel assembly thereby turns or steers in the desired direction.

Industrial Perspective:

  • The device is portable, easy to handle, highly cost-effective & reliable.
  • Facilitates a unique system for the remotely steerable hose mechanism of the fire extinguishing system intended for use in buildings & even to climb staircases.
  • Provides mechanically robust & reliable system with very small number of electronic components facing hazardous environment as in proximity to a fire.
