Description

Die vorliegende Erfindung betrifft eine Schneekanone gemäß den Merkmalen des Oberbegriffs des Anspruchs 1, eine Anordnung aus einer Schneekanone und einer Einbringungsvorrichtung, sowie ein Verfahren zur Schneeerzeugung.The present invention relates to a snow gun according to the features of the preamble of claim 1, an arrangement of a snow gun and a delivery device, and a method for snow production.

Vorrichtungen zur künstlichen Erzeugung von Schnee, gemeinhin bekannt als Schneekanonen, existieren in verschiedensten Ausführungsformen. Als gemeinsames Prinzip ist anzusehen, dass stets ein Luftstrom erzeugt wird, in welchen eine im Wesentlichen aus Wasser bestehende Flüssigkeit eingedüst wird. Bei genügend niedriger Temperatur des Luftstroms gefriert das Wasser im Luftstrom, sodass kleine Schnee- und Eispartikel im Luftstrom entstehen und dann beispielsweise auf einer Skipiste deponiert werden.Devices for artificial snow production, commonly known as snow cannons, exist in a variety of embodiments. As a common principle is to be considered that always an air flow is generated, in which a liquid consisting essentially of water is injected. At a sufficiently low temperature of the air flow, the water freezes in the air stream, so that small particles of snow and ice are created in the air stream and then deposited, for example, on a ski slope.

Zur Erzeugung des Luftstroms kann beispielsweise ein in einem Rohr angeordneter Propeller oder auch Druckluft dienen. Die Einbringung der Flüssigkeit geschieht meist über eine oder mehrere Düsen, welche dafür sorgen, dass die Flüssigkeit in Form von kleinen Tröpfchen in den Luftstrom eingebracht wird, wodurch ein schnelles Durchfrieren der Tröpfchen gefördert wird.For generating the air flow, for example, a propeller arranged in a pipe or also compressed air can be used. The introduction of the liquid is usually done via one or more nozzles, which ensure that the liquid is introduced in the form of small droplets in the air stream, whereby a rapid freezing of the droplets is promoted.

Im Stand der Technik ( EP 1 679 358 A1 , EP 0 585 938 A1 sowie CA 2370205 A1 ) sind verschiedenste Substanzen und Chemikalien bekannt, welche dem der Schneekanone zugeführten Wasser beigemengt werden. Dies soll einerseits Kondensationskeime für die Schneeerzeugung bereitstellen und andererseits die Außentemperatur, die notwendig ist, um mit der Kunstschneeherstellung zu beginnen, zu erhöhen.In the prior art ( EP 1 679 358 A1 . EP 0 585 938 A1 such as CA 2370205 A1 ) Various substances and chemicals are known, which are added to the snow cannon supplied water. This is intended on the one hand to provide condensation nuclei for the snow production and on the other hand to increase the outdoor temperature, which is necessary to start with the artificial snow production.

Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung und ein Verfahren bereit zu stellen, die es ermöglichen, Kunstschnee mit erhöhtem spezifischenn Volumen herzustellen als dies im Stand der Technik der Fall ist.The object of the present invention is to provide an apparatus and a method which make it possible to produce artificial snow with a higher specific volume than is the case in the prior art.

Hinsichtlich der Vorrichtung wird diese Aufgabe durch eine Schneekanone mit den Merkmalen des Anspruchs 1, sowie eine Anordnung aus einer Schneekanone und einer Einbringungsvorrichtung mit den Merkmalen des Anspruchs 2 gelöst. Hinsichtlich des Verfahrens wird diese Aufgabe durch die Merkmale des Anspruchs 10 gelöst.With regard to the device, this object is achieved by a snow gun with the features of claim 1, and an arrangement of a snow gun and a delivery device with the features of claim 2 solved. With regard to the method, this object is solved by the features of claim 10.

Weitere vorteilhafte Ausführungsformen der Erfindung ergeben sich aus den abhängigen Ansprüchen.Further advantageous embodiments of the invention will become apparent from the dependent claims.

Eine erfindungsgemäße Einbringungsvorrichtung kann an der Schneekanone selbst montiert sein, oder von der Schneekanone separat ausgeführt und im Luftansaugbereich der Schneekanone angeordnet sein.An insertion device according to the invention can be mounted on the snow gun itself, or be performed separately from the snow gun and arranged in the air intake of the snow gun.

Ein Kerngedanke der Erfindung ist es, nicht der Flüssigkeit, sondern dem Luftstrom einen Zusatz beizumischen. Dieser Zusatz stellt vorzugsweise Kondensationskeime bereit, welche dann schon im Luftstrom vorliegen, bevor die Flüssigkeit beigemischt wird. Denn tatsächlich ist eine Hydrathülle, so wie sie bei in der Flüssigkeit vorliegenden Kondensationskeimen besteht, hinderlich für das Wachstum von Schneekristallen. Wegen des schnellen Durchfrierens der Wassertröpfchen, in welchen die Kondensationskeime vorliegen, entstehen in diesem Fall bevorzugt Eiskristalle. Diesen fehlt die typische dendritische Ausbildung von Schneekristallen, welche dazu in der Lage sind, große Mengen von Luft einzuschließen. Dadurch entsteht der von Skipisten bekannte stumpfe Kunstschnee. Die Erfindung ermöglicht es also, einen Schnee mit geringerer Dichte bzw. erhöhtem spezifischen Volumen herzustellen, welcher dann vom Wintersportler als lockerer und weniger stumpf empfunden wird.A core idea of the invention is to add an additive not to the liquid but to the air stream. This additive preferably provides condensation nuclei which are then already present in the air stream before the liquid is added. In fact, a hydration shell, as it exists in condensation nuclei present in the liquid, hinders the growth of snow crystals. Because of the rapid freezing of the water droplets in which the condensation nuclei are present, in this case preferably ice crystals. These lack the typical dendritic formation of snow crystals that are capable of trapping large amounts of air. This creates the well-known of ski slopes blunt artificial snow. The invention thus makes it possible to produce a snow with lower density or increased specific volume, which is then perceived by the winter sportsman as looser and less dull.

Bevorzugte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen definiert.Preferred embodiments of the invention are defined in the dependent claims.

Um das dentritische Schneewachstum zu befördern, kann es vorgesehen sein, dass die Einbringungsvorrichtung zur Einbringung eines im Wesentlichen trockenen Zusatzes geeignet ist.In order to convey the dendritic snow growth, it can be provided that the introduction device is suitable for introducing a substantially dry additive.

Kondensationskeime können am einfachsten dadurch bereit gestellt werden, indem die Einbringungsvorrichtung zur Einbringung im Wesentlichen pulverförmigen Zusatzes geeignet ist. Anders ausgedrückt kann das Einbringen feinster scharfkantiger Nukleationskeime, vorzugsweise in Form eines Staubes in den Luftstrom für eine erhöhte Ausbeute an Schneemenge sorgen.Condensation nuclei can be most easily provided by the introduction device is suitable for introducing substantially powdery additive. In other words, the introduction of finest sharp nucleation nuclei, preferably in the form of a dust in the air stream for an increased yield of snowfall provide.

Besonders bevorzugt kann es vorgesehen sein, dass ein Gesteinsmehl als Zusatz in den Luftstrom eingebracht wird. Insbesondere Quarzmehl kann dabei besonders gut geeignet sein, da es auf kleinen Skalen sehr scharfkantig ist, was das Anfrieren von Wassermolekülen befördert.Particularly preferably, it can be provided that a rock flour is introduced as an additive in the air flow. In particular, quartz flour can be particularly well suited because it is very sharp on small scales, which promotes the freezing of water molecules.

Für eine feine Verteilung der Kondensationskeime im Luftstrom kann gesorgt werden, indem die Einbringungsvorrichtung einen Zerstäuber, insbesondere einen Druckluftzerstäuber oder einen Ultraschallzerstäuber, aufweist.For a fine distribution of condensation nuclei in the air flow can be ensured by the introduction device comprises a nebulizer, in particular a compressed air atomizer or an ultrasonic atomizer.

Es kann aber auch vorgesehen sein, dass die Einbringungsvorrichtung wenigstens ein in den Luftstrom und/oder in einen Teller mündendes Fallrohr aufweist. In einer solchen Ausführungsform wird der Zusatz durch den Luftstrom vom Fallrohr oder vom Teller mitgerissen, was ebenfalls eine gute Verteilung der Kondensationskeime im Luftstrom erzeugen kann.But it can also be provided that the introduction device has at least one opening into the air flow and / or in a plate drop tube. In such an embodiment, the additive is entrained by the air flow from the downpipe or from the plate, which can also produce a good distribution of the condensation nuclei in the air flow.

Bevorzugt kann vorgesehen sein, dass die Mischeinrichtung der Schneekanone so ausgeführt ist, dass mittels der Mischeinrichtung die Flüssigkeit vermengt mit Druckluft dem Luftstrom beimischbar ist.Preferably, it can be provided that the mixing device of the snow gun is designed so that by means of the mixing device, the liquid mixed with compressed air is admixed to the air stream.

Schutz wird ebenfalls für die Verwendung einer Einbringungsvorrichtung zur Einbringung eines Zusatzes in einen Ansaugbereich einer Schneekanone begehrt.Protection is also sought for the use of a delivery device for introducing an additive into a suction area of a snow gun.

Die in Figur 1a dargestellte Schneekanone 1 verfügt als Beschleunigungsvorrichtung 2 zur Erzeugung eines Luftstroms L über einen Propeller, welcher in einem Rohr angeordnet ist. An dem Ende, an welchem der Luftstrom L aus dem Rohr austritt, ist eine Vielzahl von Düsen als Mischeinrichtung 4 angeordnet. Diese wird über die Zuleitung 3 aus einem Wasserreservoir W beschickt.In the FIG. 1a illustrated snow gun 1 has as accelerator 2 for generating an air flow L via a propeller, which is arranged in a pipe. At the end at which the air flow L exits the tube, a plurality of nozzles is arranged as a mixing device 4. This is fed via the supply line 3 from a water reservoir W.

Die Einbringungsvorrichtung 5 ist in diesem Fall als Druckluftzerstäuber 7 ausgeführt. Dieser verfügt über einen Trichter 11, über welchen der Zusatz Z zugeführt wird. Mittels Druckluft aus der Druckluftleitung 9 wird der Zusatz Z zerstäubt und über Kanäle 6 (in diesem Fall Schläuche) dem Luftstrom beigemischt. Diese Beimischung erfolgt in dieser Ausführungsform in Richtung des Luftstroms L nach der Beschleunigungsvorrichtung 2. Zur Erzeugung des Drucks in der Druckluftleitung 9 dient ein Kompressor 8. Solche Kompressoren 8 sind häufig schon Teil einer Schneekanone 1.The introduction device 5 is designed in this case as Druckluftzerstäuber 7. This has a funnel 11, via which the additive Z is supplied. By means of compressed air from the compressed air line 9, the additive Z is atomized and mixed via channels 6 (in this case hoses) the air flow. This admixing takes place in this embodiment in the direction of the air flow L after the acceleration device 2. To generate the pressure in the compressed air line 9 is a compressor 8. Such compressors 8 are often already part of a snow gun 1.

Kompressoren 8 dienen bei Schneekanonen 1 ebenfalls dazu Druckluft zu erzeugen, welche mit Wasser vermengt wird. Beim Austritt aus den Düsen der Mischeinrichtung 4 tritt eine Expansion der Druckluft ein, welche das Energieniveau senkt und das Gefrieren des Wassers einleitet. Dies ist auch im Ausführungsbeispiel zu Fig. 1a realisiert, jedoch nur schematisch dargestellt.Compressors 8 are used in snow cannons 1 also to generate compressed air, which is mixed with water. Upon exiting the nozzles of the mixing device 4 occurs an expansion of the compressed air, which lowers the energy level and initiates the freezing of the water. This is also the case in the exemplary embodiment Fig. 1a realized, but only shown schematically.

Es ist nur einer der als Schläuche ausgeführten Kanäle 6 mit einem Bezugszeichen versehen, was der Übersichtlichkeit dienen soll (gilt auch für Figur 2). Die Kanäle 6 sind an ihren Enden mit Düsen 12 versehen, welche aus Sicht entlang des Luftstroms L sternförmig angeordnet sind (Figur 1 b).It is only one of the channels designed as hoses 6 provided with a reference numeral, which is to serve clarity (also applies to FIG. 2 ). The channels 6 are provided at their ends with nozzles 12 which are arranged star-shaped as viewed along the air flow L ( FIG. 1 b) ,

Eine ähnliche Ausführungsform ist in Figur 2 dargestellt. Die Einbringung des Zusatzes Z erfolgt in dieser Ausführungsform entlang des Luftstroms L vor der Beschleunigungsvorrichtung 2. Für den Grundgedanken der Erfindung ist es nicht wesentlich, ob die Beimischung vor oder nach der Beschleunigungsvorrichtung 2 geschieht. Wichtig ist lediglich, dass die Einbringung entlang des Luftstroms L vor der Beimischung der Flüssigkeit durch die Mischeinrichtung 4 geschieht. Die Anordnung der Düsen 12 an den Enden der Kanäle 6 ist ebenfalls wie in Figur 1b dargestellt.A similar embodiment is in FIG. 2 shown. The introduction of the additive Z takes place in this embodiment along the air flow L in front of the accelerator 2. For the basic idea of the invention, it is not essential whether the admixture occurs before or after the accelerator device 2. The only important thing is that the introduction along the air flow L before the Admixing of the liquid by the mixing device 4 happens. The arrangement of the nozzles 12 at the ends of the channels 6 is also as in FIG FIG. 1b shown.

Figur 3 zeigt, ebenfalls rein schematisch, eine erfindungsgemäße Anordnung aus einer Schneekanone 1 und einer Einbringungsvorrichtung 5, wobei die Schneekanone 1 in diesem Fall im Wesentlichen dem Stand der Technik entsprechend ausgeführt ist. FIG. 3 shows, also purely schematically, an inventive arrangement of a snow gun 1 and a delivery device 5, wherein the snow gun 1 is executed in this case substantially according to the prior art.

Die Einbringungsvorrichtung 5 weist in diesem Fall ein auf einen Teller 8 mündendes Fallrohr 9 auf, welches über einen Trichter 11 mit dem Zusatz Z beschickt wird.In this case, the introduction device 5 has a drop tube 9 opening onto a plate 8, which is charged with the additive Z via a funnel 11.

Der Sog, welcher hinter der Schneekanone 1 durch die Erzeugung des Luftstroms L entsteht, reißt den Zusatz Z vom Teller 8 mit, wodurch der Luftstrom L mit dem Zusatz Z beladen wird.The suction, which arises behind the snow gun 1 by the generation of the air flow L, tears the additive Z from the plate 8, whereby the air flow L is loaded with the additive Z.

Die in Figur 4 dargestellte Schneekanone 1 ist in Ihrer Ausführung ähnlich zu in Figur 3 dargestellten Anordnung. Der Unterschied besteht darin, dass die Einbringungsvorrichtung 5, wie in den Ausführungsformen aus Figur 1 und 2, an der Schneekanone befestigt ist. Natürlich ist es für den Grundgedanken der Erfindung nicht wesentlich, wo die Einbringungsvorrichtung 5 befestigt ist. Ausführungsformen gemäß den Figuren 3 und 4 haben den Vorteil der leichten Nachrüstbarkeit. Die Ausführungsformen der Figuren 1 und 2 können unter Umständen eine bessere Verteilung des Zusatzes Z im Luftstrom L erreichen.
Die vorliegende Erfindung ist nicht auf die hier dargestellten Ausführungsbeispiele beschränkt. Beispielsweise ist es ohne Weiteres möglich, den Luftstrom L mittels Druckluft zu erzeugen. Die Beschleunigungsvorrichtung 2 wäre in diesem Fall also durch eine Druckluftflasche, einen Kompressor oder dergleichen Mittel zur Erzeugung der Druckluft gebildet.In the FIG. 4 illustrated snow cannon 1 is similar in its execution to in FIG. 3 illustrated arrangement. The difference is that the introduction device 5, as in the embodiments of FIG. 1 and 2 , attached to the snow cannon. Of course, it is not essential to the basic idea of the invention where the delivery device 5 is attached. Embodiments according to the Figures 3 and 4 have the advantage of easy retrofitting. The embodiments of the FIGS. 1 and 2 may possibly achieve a better distribution of the additive Z in the air stream L.
The present invention is not limited to the embodiments shown here. For example, it is readily possible to generate the air flow L by means of compressed air. The acceleration device 2 would be formed in this case by a compressed air cylinder, a compressor or the like means for generating the compressed air.

Die in Figur 5 dargestellte Ausführungsform ist eine als Schneelanze (auch genannt Schneilanze) ausgeführte, erfindungsgemäße Schneekanone 1. Eine Schneelanze aus dem Stand der Technik ist beispielsweise aus der EP 2 071 258 A1 bekannt. Dabei kommt ebenfalls ein Druckluftzerstäuber 7 in Form einer Nukelatordüsezum Einsatz, der sowohl eine vergleichsweise kleine Menge an Wasser als auch der Zusatz Z zugeführt wird. Der entstehende mit dem Zusatz Z versehene Luftstrom L wird über eine Leitung 13 zur Nukleatordüse am Ende der Schneelanze geleitet und tritt dort aus. Die ebenfalls am Ende der Schneelanze angeordnete Mischeinrichtung 4 besteht in diesem Fall aus einer oder mehreren Düsen. Durch sie wird dem aus der Nukleatordüseausgetretenen Luftstrom L die Flüssigkeit - wieder im Wesentlichen Wasser aus einem Wasserreservoir W - beigemischt. Es ist zu bemerken, dass diese Mischung bei Schneilanzen außerhalb der Vorrichtung von Statten gehen kann.In the FIG. 5 illustrated embodiment is as a snow lance (also called snow lance) running, inventive snow gun 1. A Schneelanze from the prior art is for example from the EP 2 071 258 A1 known. In this case, a compressed air atomizer 7 in the form of a Nukelatordüsez also used, which is supplied to both a comparatively small amount of water and the additive Z. The resulting provided with the additive Z air flow L is passed via a line 13 to the nucleation nozzle at the end of the snow lance and exits there. The also arranged at the end of the snow lance mixing device 4 consists in this case of one or more nozzles. Through them, the liquid - again essentially water from a water reservoir W - is added to the air stream L that has leaked out of the nucleator nozzle. It should be noted that this mixture can take place at snow lances outside the device.
