Description
The present invention relates to a fire extinguishing gun for extinguishing a fire of a fire object, wherein the fire extinguishing gun comprises: a grip section having a handle member for an operator; a fire extinguishing agent supply having a coupling device for connecting a pressure hose for the liquid fire extinguishing agent; and a tubular extinguishing section which is connected to the gripping section and, if appropriate, to the coupling device, from the free end of which an extinguishing agent can be applied under pressure into an object on fire, wherein the handle part of the gripping section is also electrically insulated for a voltage U of 100V or more, the tubular extinguishing section is geometrically tapered on its free end, and the tubular extinguishing section has a narrowed clear flow cross section at its free end for the extinguishing agent which is guided through under pressure.
Such a fire extinguishing gun is known from US 2002/019307 a 1.
Similar fire guns are also described in the company catalog of Murer fire protection, llc, 2016, 05 months, particularly the "spray fire suppression system NLS" indicated therein.
Background
There is currently a strong international desire to replace fossil fuels with an intensified use of electrical energy, especially for environmental and climate protection and durability reasons. Therefore, photovoltaic systems have been increasingly built over the last years, for example on the roof of buildings. Furthermore, in the future, the individual's locomotion trip should be intensively realized by an electric drive system, for example by an electric vehicle.
However, to date, only a few concerns have been addressed, and there are also significant potential hazards associated with such enhanced utilization of electrical energy.
These potential hazards have emerged to an increasing extent in view of the large number of worldwide occurring fire events caused by malfunctioning or only poorly functioning storage batteries, for example in smartphones or notebooks.
A particularly high risk is seen when a fire breaks out in the environment of an electric vehicle, for example in the case of a hybrid or fully electrically operated vehicle (see "electric car fire in the united states"; https:// www.welt.de/motor/news/angel 120704501/E-mobile-Brand-in-den-usa. html (review data on 09 months 11/2016)).
Particularly problematic in the event of a fire in such an electric vehicle is: not only are significant hazards arising from the fire and fire itself and, for example, possible self-igniting components, such as lithium ion batteries, when fighting fires, but additionally the hazards arising from high voltages or high currents propagating due to high-power electrical devices or high-power batteries installed in the vehicle must also be controlled. It is therefore desirable to effectively prevent such hazards.
A fire extinguishing gun is described in US-a 4,802,535, in which a hardened steel tube is proposed as the material for the tubular extinguishing section. However, there is no electrical insulation (of whatever type) provided for the known fire extinguishing guns.
US 2003/0159837 a1 shows a "multipurpose water hammer" having a gradually tapering nozzle which, in use, should penetrate into the object to be extinguished. Where the extinguishing head is mounted onto the tubular extinguishing section at an angle of 90 deg.. In order to use such a device in hammer form in an electric vehicle, it must already be operated very close to the battery to be extinguished in the event of a drive into the vehicle housing, in order to achieve a fully effective result. In addition, the electrical insulation of the extinguishing gun is not provided or indicated here. Vehicles with electric drives have probably not been conceived (as today) in 2002 and 2003.
In the initially cited US 2002/019307 a1, although an insulation is shown which is resistant to voltage when in contact with wires in the building wall, no insulation is shown which is resistant to high voltages, as is present, for example, in batteries for electric vehicles. Furthermore, the extinguishing agent is fed in via the end of the known extinguishing gun, so that it is therefore also possible and impossible to achieve driving of the gun into the vehicle casing by means of a driving tool.
Other disadvantages of the prior art
Until now, firefighters have only conditionally prepared for this source of harm. In the above-mentioned article, it is reported, for example, that firefighters fighting fires with electric vehicles must reserve or maintain a significant spatial separation from the electric vehicle, which of course very significantly limits the effectiveness of fire protection or makes fire fighting measures (known per se) somewhat, if not completely impossible, in their positive effect.
In order to counteract this extended hazard, a fire-extinguishing gun is therefore required, which is not only designed for the actual fire extinguishing itself, but also is able to withstand both thermal and mechanical and, in particular, also electrical hazards.
However, until now, fire guns of the type defined at the outset have not been successfully equipped with a thermal and/or mechanical protection and additionally with a further function which also ensures compliance with (relatively stringent) regulatory standards for electrical tools. Namely, the following risks always exist at present: when extinguishing electrical objects under voltage (in particular in the wet state of fire-extinguishing guns, which is entirely typical for the use case), the voltage or current reaches the operator to an impermissibly high degree, which can therefore be significantly injured in fire-fighting use.
Object of the invention
In contrast, the object of the present invention is to provide a fire extinguishing gun which is inexpensive and cost-effective by means of technical means which are as simple as possible, and by means of which the minimum requirements for protection against both thermal and mechanical overload and electrical damage are reliably met.
Short description of the invention
According to the invention, this task, which in practice is not entirely uncomplicated, is solved in an equally surprisingly simple and extremely effective manner by a fire gun of the type defined at the outset, which is also suitable for operation in the presence of an electrical voltage,
in that the grip part of the gripping section is also electrically insulated for a voltage U of 500V or more;
in that the tubular extinguishing section is made of a material having such a high tensile strength RmHaving such a composition that the material withstands 500N/mm or more2And the material has a melting temperature t of 650 ℃ or moreS；
And in that the gripping section has, at the operator-side end, a large-area impact plate in extension with respect to the tubular extinguishing section.
The invention provides an E-lance which fully solves the above-stated object of the invention. In particular, the fire extinguishing gun according to the present invention is of a first type thereof, which is specifically adapted for extinguishing a lithium ion battery installed in an electric vehicle. Thus, fire fighting units are now provided with a first effective fire extinguishing device worldwide for this application as well.
The large-area striking plate on the operator-side end of the gripping section serves to establish a planar body contact with the operator. The impact plate, which is mounted centrally, ensures in particular that the gun is driven as straight as possible, in order to prevent the gun from bending. In addition, a spacer section can also be provided in connection with the impact plate, which spacer section is opposite the tubular extinguishing section.
In use, the gun may be introduced into the battery of a fired electric vehicle, for example. Due to the tip in the foremost region, material in the path, for example the cell wall, can easily be penetrated. Wear is avoided or at least minimized by such a high-strength, but sharp nozzle, wherein penetration into the surface of the object to be extinguished is facilitated.
The flow-narrowing nozzle at the tip of the lance additionally takes care of: a sufficiently successful fire extinction can be achieved quickly and efficiently and in particular with relatively little use of extinguishing water.
There is currently no alternative viable solution for directly and reliably extinguishing an electric vehicle battery. The factory fire brigades of well-known automobile manufacturers, in numerous tests, have almost completely failed to control fires in electric vehicles without the E-guns (electric fire guns) according to the invention and only with the use of an extremely large amount of water and foam, but nevertheless have no effective security against voltage for the active fire fighters.
Furthermore, the behavior is also completely similar when extinguishing a fire in a transformer or generator that is trapped in a fire, for example in the case of photovoltaic installations.
Preferred embodiments of the invention
A particularly advantageous first embodiment of the E-lance according to the invention is characterized in that the grip part of the grip section has a voltage-insulating coating. The grip part itself can thus already ensure that the operator is adequately protected against voltage. Particularly preferred is a further development of this embodiment, which is characterized in that the voltage-insulating coating of the grip part is also designed for voltages U of 1000V or more.
In this connection, it is advantageous if the voltage-insulating coating of the handle part itself already meets at least the minimum requirements, namely european standard 60903 and/or 659 for insulating protective gloves for operation in the presence of a voltage. Furthermore, it is advantageous if the voltage-insulating coating of the handle part is made of a thermally insulating, fire-resistant material (for example, if aramid and/or para-aramid are used) and also meets the minimum requirements of european standard 407 for protective gloves against thermal risks.
It is particularly advantageous if the voltage-insulating coating of the grip part has a layer thickness d of 2mm or more, which technically enables the use of up to 1000V and even above.
In a further development of the primary embodiment described above, the voltage-insulating coating of the grip part is preferably made of polyvinyl chloride. Thereby, a longer service life of the coating is ensured. The aging phenomenon is minimized.
A particular advantage is achieved in a further development in which the grip section is formed from a metal, preferably VA steel, in particular austenitic, acid-resistant 18/10Cr — Ni steel, under the voltage-insulating coating of the grip part. This material is resistant and particularly resistant to battery acids.
In a further advantageous embodiment of the E-fire gun according to the invention, the grip part of the gripping section has at least one arcuate grip with a hand guard. This enables reliable operability and good positioning of the battery. In addition, the arcuate shaped handle serves as a protective structure to prevent undesired deformation of the gun when driven into a fire extinguishing object.
This embodiment of the stage can be further improved by a further development in which the handle part of the grip section has two arcuate handles for two-handed operation of the E-fire gun. Thereby, a reliable operability and positioning in the fire extinguishing object that should be penetrated is ensured.
A further advantageous embodiment is characterized in that an actuating valve for admitting the flow of extinguishing agent into the tubular extinguishing section or for stopping the flow of extinguishing agent into the tubular extinguishing section is provided on the extinguishing agent supply, and in that a triggering device for manual actuation of the actuating valve is provided on the gripping section, preferably on the handle part.
In a further preferred embodiment of the invention, the tubular extinguishing section is made of metal, preferably stainless steel, in particular austenitic, acid-resistant 18/10Cr — Ni steel. This contributes to an increased mechanical and chemical resistance and thus to a longer durability of the tip.
Preferably, the E-lance according to the invention is also embodied in such a way that the free end of the tubular extinguishing section is of a tapered design. This makes it possible to drive the workpiece in a particularly straight line and easily.
The tapering free end of the tubular extinguishing section can in a further embodiment of the invention be made of an austenitic, acid-resistant, preferably hardened 18/10Cr — Ni steel. This material selection and processing variant in turn ensures high resistance and resistance.
Particularly preferred is a first-order embodiment in which the tapering free end of the tubular extinguishing section is configured to be replaceable. Thus, the gun can also be used for other fire suppressant variants. Furthermore, in the event of wear, the tip can therefore be replaced quickly and simply by another tip.
An advantageous further development of this primary embodiment is characterized in that different exchangeable tips, preferably with different geometries, diameters and in particular different materials, can be provided and can be held in stock for the most different purposes of use. As a result, the E-lance according to the invention is quickly made available again in the event of wear. The tip can also be replaced in situ, directly in the case of use, likewise quickly.
Preferably, a further development is provided in which the exchangeable tip is provided with a screw thread or, for example, also with a bayonet lock, wherein preferably two holding points for a wrench are present for easy removal. This makes the gun quickly available again in the event of wear and, in the event of use, the tip can likewise be quickly replaced.
In a further particularly advantageous embodiment of the E-lance according to the invention, at least one nozzle for discharging the liquid extinguishing agent under pressure is integrated into the tapering free end of the tubular extinguishing section, wherein the nozzle is preferably shaped such that it optimally sprays the extinguishing agent into the burning object and/or distributes it onto the surface of the burning object. In this way only a relatively small amount of extinguishing agent is required.
In practice, it has been tested that this stage of embodiment is a further development in which the nozzle has a net diameter of between 30mm and 40mm, preferably about 33.7mm, a length of between 25mm and 50mm, preferably about 30mm, and a width of between 15mm and 25mm, preferably 21.3 mm. These special dimensions also have advantages in particular with regard to manufacturing technology.
Finally, a further advantageous further development of this stage of embodiment is characterized in that three nozzles are provided which are arranged uniformly distributed around the longitudinal axis of the tubular extinguishing section. In this way, a targeted and uniform penetration of the extinguishing agent into the extinguishing object can be ensured in the case of use.
In practice, the embodiment of the fire extinguishing gun according to the invention in which the large-area impact plate is made of solid material and is preferably designed to be replaceable has proved to be problematic.
Likewise, an embodiment is advantageous which is characterized in that the extinguishing gun, in particular the striking plate, is constructed to be detachable. The fire extinguishing gun according to the invention can therefore be used particularly flexibly, for example in the event of a fire in a garage of its own or in a parking lot. In this connection, for example, lithium ion batteries are subject to spontaneous combustion as a result of compression, which leads to fires and serious damage in buildings.
Particularly advantageous is an embodiment of the invention in which the extinguishing gun is configured to be extendable with respect to its longitudinal axis, wherein in particular the striking plate on the operator-side end of the gripping section is arranged at a variable distance from the tubular extinguishing section, said distance preferably being configured to be extendable. Thus, a higher flexibility in terms of application is also achieved. By this design, the fire suppression gun is particularly suitable for use in trucks and other large vehicles.
