Definitions
- the invention is directed to a fire fighting method using an extinguishing agent thrower, in particular an extinguishing agent nozzle of a hand-held extinguisher, wherein an extinguishing agent jet when actuating an activation element is released, as well as on a device in particular to carry out the procedure.
- Extinguishing powder ejecting nozzles are often with a funnel widening outwards equipped to generate a powder cloud.
- the one using the hand-held extinguisher Carry out swiveling movements to increase the extinguishing effect or otherwise try the jet of extinguishing agent then atomize when using a wider area Extinguishing media should be painted over.
- DE-U-1 782 540 DE-A-1 948 510 or US-5 344 080 nozzles are known with which different Beam training can be made possible, in particular with regard to personal protection, e.g. in Art a "personal protection shower".
- the object of the invention is to provide a solution with which works in both procedural as well is improved in terms of device, with the particular an inexperienced person in fighting a fire is put into position by hand with small fire extinguishers, delete more effectively.
- this object is achieved in that the nozzle head of the extinguishing agent nozzle with at least two different ones Extinguishing agent jet generating nozzle mouths equipped is.
- the invention is the targeted combination of extinguishing agents possible with coordinated effect, i.e. it can be achieve multiple erasure effects at the same time, such as disconnection, Energy withdrawal, inhibition effects, mechanical effects and. Like., These effects are achieved without the user must take special measures.
- the extinguishing agent can be used as a liquid, Ejected foam, gas or powder; depending on the physical state of the extinguishing agent can be an extinguishing agent itself be outfitted in different ways.
- the extinguishing agent can be distributed asymmetrically be ejected from the extinguishing agent nozzle. It can be appropriate, if necessary, the extinguishing agent at least with one concentrated penetrating jet and a fanned flat jet eject.
- a special procedure is that as an extinguishing agent Inert gases, such as an extinguishing liquid Water, foams or powder for extinguishing agents, in particular for production an extinguishing agent penetration zone, a cooling zone and a separation zone at the source of the fire.
- Inert gases such as an extinguishing liquid Water, foams or powder for extinguishing agents, in particular for production an extinguishing agent penetration zone, a cooling zone and a separation zone at the source of the fire.
- Embodiments of the device according to the invention are thereby given that the nozzle head with a penetrating jet generating nozzle mouth and another nozzle mouth equipped is, the further nozzle mouth to produce a oscillating point beam, a flat beam or one Extinguishing agent mist can be designed according to the invention.
- the nozzle head with a penetrating jet generating nozzle mouth and another nozzle mouth equipped is, the further nozzle mouth to produce a oscillating point beam, a flat beam or one Extinguishing agent mist can be designed according to the invention.
- the alternative between two such, different Extinguishing agent jets are provided, but several, such as flat jet, spot beam and fog as an oscillating point beam or oscillating fog beam, to name just a few examples.
- the design can be made, for example, that the nozzle mouth for the penetrating jet and the nozzle mouth for the flat jet spatially separated or in each other are continuously formed on the nozzle head.
- the nozzle head with a Screw-in thread for screwing in different designs Nozzle mouth is provided, which may also be provided can that the nozzle head is designed as a retrofit part made of plastic is.
- the device generally designated 1, is shown in FIGS. 1 and 3 shown only symbolically, it essentially exists from an extinguishing agent nozzle 2 or 2a with a symbolically indicated actuator 3 or 3a, one Feed 4 or 4a for the extinguishing agent and one with 5 or 5a designated nozzle head.
- 5 to 9 are the top views of the nozzle heads 5 shown with different nozzle mouths 6 according to the invention up to 6d.
- nozzle mouth 6 for generation an intrusion jet
- nozzle mouth 6a to generate an oscillating point beam
- a large number of small-hole nozzle mouths 6b for producing a Extinguishing agent mist, e.g. is used for cooling.
- Fig. 6 the top view of the nozzle head is a penetrating jet nozzle mouth 6 to see the nozzle mouth 6b for generation of a mist and a nozzle mouth 6c for generating a Flat jet.
- FIG. 7 and 8 show modified embodiments, namely the physical connection between the penetrating jet nozzle mouth 6 with flat jet nozzle mouth 6c with and without mist nozzle head 6b.
- FIG. 9 and 10 is a design similar to that in Fig. 6, wherein in Fig. 10 a corresponding principle Cross-sectional drawing is reproduced, the removable is that from a source of extinguishing agent, not shown, in Fig. 10 hinted at 7, the subsidized extinguishing agents are distributed over two nozzle heads can, e.g. on the nozzle 6, which generates an penetrating jet, and the nozzle 6c, which generates a flat jet.
- FIG. 11 A a similar modified design is shown in FIG. 11.
- nozzle head 5 as Retrofit part that can be screwed into a screw thread 8 is, can be designed.
- FIG. 12 and 13 are in different display variants those in question, from a nozzle head shown extinguishing agent jets, wherein in Fig. 12 above a fog 10, in the middle a penetrating jet 11 and a flat jet 12 is indicated below.
- Fig. 13 it is indicated that e.g. from a nozzle head qualitatively different extinguishing agents can be ejected, about a mist 10a from an inert gas, a flat jet 12 and an oscillating beam 13 from another Extinguishing agent.
- 2 and 4 are different types of fire fighting 1 and 3, the respective, usually penetration zone created by the penetration jet with 14, the cooling zone with 15 and the separation zone with 16 which is recognizable depending on the nozzle shape adopt geometric configurations or concentrations can.
