Abstract

A mobile snow generator for winter sports has a chassis with an ice block holder resting on a lift/lower floor. The floor holds an ice block (i) that is exposed to a traversing rotary cutter and air blower. The cutter blade generates fine powder snow.

Description

Die Erfindung betrifft eine fahrbare Schneeerzeugungsmaschine zur Gewinnung von Schnee aus Eisblöcken zur Beschneiung von Skipisten, wobei die Eisblöcke zerkleinert werden.The The invention relates to a mobile snow-making machine for extraction of snow from blocks of ice for snowmaking of ski slopes, whereby the ice blocks are crushed.

Die Durchschnittstemperaturen auf der Erde sind in den vergangenen Jahren kontinuierlich angestiegen. Durch diese Tatsache Werden die Winter milder. Der Schneefall setzt meist später und auch in geringerem Umfang ein. Die Schneesicherheit der Skipisten hat sich somit erheblich verschlechtert. Insbesondere im Mittelgebirgsraum und in den tieferen Lagen der Alpenregionen ist die Schneesicherheit zum Teil nur unter Einsatz von künstlicher Beschneiung gewährleistet.The Average temperatures on Earth have been in recent years continuously increased. This fact makes the winter milder. The snowfall usually sets later and also to a lesser extent. The snow safety of the ski slopes has thus deteriorated considerably. Especially in the low mountain area and in the lower elevations of the Alpine regions, snow is guaranteed Part only using artificial Snowmaking guaranteed.

Zur künstlichen Beschneiung werden in den letzten Jahren mehr und mehr so genannte Schneekanonen eingesetzt. Dieser Einsatz erfordert einen sehr hohen Wasser- und Stromverbrauch, die durch kostspielige Anlagen sichergestellt werden müssen. Außerdem können Schneekanonen nur bei Minusgraden eingesetzt werden.to artificial Snowmaking is becoming more and more so called in recent years Used snow cannons. This use requires a very high Water and electricity consumption ensured by costly equipment Need to become. In addition, snow cannons only be used at temperatures below freezing.

Die EP 0 399 946 A1 zeigt als Alternative eine fahrbare Schneeerzeugungsmaschine. Dort werden Eisblöcke durch Messerwellen zerkratzt, wodurch aber sehr kleine Eispartikel entstehen.The EP 0 399 946 A1 shows as an alternative a mobile snow-making machine. There, ice blocks are scratched by knife shafts, which causes very small ice particles.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Schneeerzeugungsmaschine anzugeben, die einen niedrigen Wasser- und Stromverbrauch aufweist, bei Temperaturen über Null Grad arbeiten kann und qualitativ hochwertigen Schnee liefert, der dem Naturschnee sehr ähnlich ist.Of the The invention is therefore based on the object, a snow-making machine which has a low water and electricity consumption, at temperatures above Can work zero degrees and delivers high quality snow, very similar to natural snow is.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Hauptanspruchs gelöst.These The object is achieved by the Features of the main claim solved.

Für die benötigten Eisblöcke in einer Größe von z.B. 2,00 × 3,00 m und einer Stärke von 1,00 m kann das benötigte Wasser in Hochlagen des Gebirges im Sommer oder Herbst aufgefangen und in vorbereitete Formen oder flache Teiche geleitet werden. Bei einsetzendem Frost gefriert das Wasser auf natürlichem – oder auch auf künstlichem – Wege zu festen Eisblöcken, die so transportiert und bearbeitet werden können.For the required ice blocks in one Size of e.g. 2.00 × 3.00 m and a strength from 1.00 m can the needed Water collected in high altitudes of the mountains in summer or autumn and be directed into prepared shapes or shallow ponds. at the frost freezes the water in natural - or artificial - ways to solid ice blocks, which can be transported and processed.

Wenn man Eis dünnschichtig abhobelt oder abfräst, entsteht aus den abgetrennten Eispartikeln Pulverschnee. Diese Eisblöcke werden daher durch die fahrbare Schneeerzeugungsmaschine ähnlich einem Dicken-Hobel durch hochtourige Messerwellen abgehobelt bzw. abgefräst.If you ice thinly plane or milled off, arises from the separated ice particles powder snow. These ice blocks will be therefore by the mobile snow-making machine similar to one Thick plane planed by high-speed knife shafts or milled off.

Die Anlage kann elektronisch so gesteuert werden, dass die Messerwelle Eisspäne in einer Stärke von ca 1/10 mm abhobelt. Der gewonnene Pulverschnee wird dann durch eine Gebläseeinrichtung auf die Piste geblasen.The Plant can be electronically controlled so that the knife shaft ice chips in a strength planed off from about 1/10 mm. The recovered powder snow is then through a blower device blown on the slopes.

Die erfindungsgemäße fahrbare Schneeerzeugungsmaschine kann als selbsttätige, mit Verbrennungsmotoren angetriebene Maschine oder als Hänger an Pistenwalzen eingesetzt werden. Besondere Wasser- und Stromanschlüsse sind nicht erforderlich.The movable according to the invention Snow making machine can be used as an automatic, with internal combustion engines powered machine or as a trailer be used on piste rollers. Special water and electricity connections are not mandatory.

Weitere Vorteile der vorliegenden Erfindung ergeben sich aus der folgenden Beschreibung mehrerer Ausführungsbeispiele sowie aus den Zeichnungen auf die nun Bezug genommen wird.Further Advantages of the present invention will become apparent from the following Description of several embodiments and from the drawings to which reference is now made.

In den A und B ist das System einer fahrbaren Schneeerzeugungsmaschine zur Gewinnung von Schnee aus Eisblöcken dargestellt. Es besteht aus dem Fahrgestell a mit Rädern b, hinteren Luftschlitzen c, der horizontal beweglichen Messerwelle d, Messerblättern e, dem Antriebsmotor f, dem Hubboden g, dem Gebläse h und dem Eisblock i.In the A and B the system of a mobile snow-making machine for obtaining snow from ice blocks is shown. It consists of the chassis a with wheels b, rear louvers c, the horizontal movable blade shaft d, knife blades e, the drive motor f, the lifting base g, the blower h and the ice block i.

In der C ist eine Alternative zu Schälmessern dargestellt. Die Messerwelle hat eine größere Länge als die Breite der Eisblöcke und ist mit gezähnten Messerblättern ausgestattet. Bei diesen Messerblättern sind jeweils zwei so aufeinander abgestimmt, dass sich die Schnittflächen geringfügig überlappen.In the C is an alternative to peeling knives shown. The knife shaft has a greater length than the width of the ice blocks and is equipped with toothed knife blades. Two of these blades are matched so that the cut surfaces overlap slightly.
