Abstract

On a snow cannon having a fan tube (1), through which air flows and at the end of which nozzles (3) are disposed for introducing water and compressed air into the exiting spray jet, wherein valves (4) are connected upstream of the nozzles (3), the valves (4) are controlled with compressed air, for which purpose pilot control valves (7) are provided.

Description

Schneekanone mit einem Lüfterohr Snowblower with a fan-ear
Die Erfindung bezieht sich auf eine Schneekanone mit einem Lüfterrohr, das von Luft durchströmt wird und an dessen Ende Düsen zum Einbringen von Wasser und Druckluft in den austretenden Sprühstrahl angeordnet sind, wobei den Düsen Ventile vorgeschaltet sind.The invention relates to a snow gun with a fan tube, which is traversed by air and at the end of nozzles for introducing water and compressed air are arranged in the exiting spray, wherein the nozzle valves are connected upstream.
Zur Sicherung der Skisaison bzw. Befahrbarkeit von Abfahrtsstrecken oderTo secure the ski season or trafficability of downhill courses or
Pisten auch bei fehlendem bzw. nicht ausreichendem Schneefall werden heute in zunehmenden Maße Schneekanonen eingesetzt. Bei bekannten Schneekanonen werden die den Düsen vorgeschalteten Ventile elektrisch oder händisch betätigt. Elektrisch bzw. elektromagnetisch betätigte Ventile sind verhältnismäßig teuer und groß.Slopes even in the absence or insufficient snowfall are now increasingly used snow cannons. In known snow guns the valves upstream of the nozzles are operated electrically or manually. Electrically or electromagnetically actuated valves are relatively expensive and large.
Die Erfindung hat es sich zum Ziel gesetzt, eine Schneekanone zu schaffen, deren Ventile kleiner und billiger sind.The invention has set itself the goal of creating a snow gun, the valves are smaller and cheaper.
Erreicht wird dies dadurch, dass die Ventile mit Druckluft angesteuert werden, wozu Vorsteuerventile angeordnet sind.This is achieved by the fact that the valves are controlled by compressed air, to which pilot valves are arranged.
Der Vorteil der Erfindung liegt insbesondere darin, dass kleine Vorsteuerventile große Arbeitsventile steuern, wobei die Vorsteuerventile in einem beheizten Schrank angeordnet sein können.The advantage of the invention is in particular that small pilot valves control large working valves, wherein the pilot valves can be arranged in a heated cabinet.
Nachstehend ist die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben, ohne auf dieses Beispiel beschränkt zu sein. Dabei zeigt die einzige Figur schematisch eine erfindungsgemäße Schneekanone.The invention is described in more detail below with reference to an embodiment shown in the drawing, without being limited to this example. The single figure shows schematically a snow gun according to the invention.
Gemäß der Zeichnung wird das Lüfterrohr 1 einer Schneekanone in Richtung des Pfeiles 2 von Luft durchströmt. Diese Luft wird durch ein am anderen Ende des Lüfterrohres 1 angeordnetes Gebläse erzeugt. Am Ende des Lüfterrohres 1 sind Düsen 3 angeordnet, die Wasser und Druckluft in den austretenden Sprühstrahl einbringen.According to the drawing, the fan tube 1 of a snow gun in the direction of arrow 2 is traversed by air. This air is generated by a fan arranged at the other end of the fan tube 1. At the end of the fan tube 1 nozzles 3 are arranged to bring water and compressed air in the exiting spray.
Den Düsen 3 sind Ventile 4 vorgeschaltet. Diesen Ventilen 4 wird Wasser über die Leitung 5 und Druckluft über die Leitung 6 zugeführt.The nozzles 3 valves 4 are connected upstream. These valves 4 water is supplied via the line 5 and compressed air via line 6.
Gesteuert werden die Ventile 4 von Vorsteuerventilen 7. Diesen Vorsteuerventile 7 wird Druckluft über die Leitung 8 zugeführt.The valves 4 are controlled by pilot valves 7. These pilot valves 7 are supplied with compressed air via the line 8.
Die Ventile 4 werden über Druckluftleitungen 9 von den Vorsteuerventilen 7 angesteuert. Die Vorsteuerventile 7 können in einem beheizten Schrank angeordnet sein und sind weitaus kleiner als die Ventile 4.The valves 4 are controlled by the pilot valves 7 via compressed air lines 9. The pilot valves 7 may be arranged in a heated cabinet and are much smaller than the valves 4.
Im Rahmen der Erfindung sind zahlreiche Abänderungen möglich. In der Zeichnung sind die Vorsteuerventile 7 nahe den Ventilen 4 dargestellt, jedoch ist dies nur zur Veranschaulichung der Erfindung gewählt, tatsächlich werden die Vorsteuerventile 7 weiter von den Ventilen 4 entfernt sein. Numerous modifications are possible within the scope of the invention. In the drawing, the pilot valves 7 are shown near the valves 4, but this is only chosen to illustrate the invention, in fact, the pilot valves 7 will be further away from the valves 4.
