Abstract

The sprinkler installation proposed comprises at least one feed pipe (10) which is mounted on the parallel side walls of the riding hall so that it can travel with a reciprocating motion and which is fitted with a multiplicity of sprinkler heads (11). The supply end of the feed pipe is connected to a pump (12), the suction side of which is connected via a pipe (13) to an open channel (14) running parallel to the path of travel of the feed pipe and supplied with water, thus allowing water to flow from the channel to the pump. The sprinkler installation described gives wide-area coverage of the floor and absolutely uniform water distribution.

Description

Bewässerungsanlage für Irrigation system for

Hallenböden von Reithallen,Hall floors of riding arenas,

Treibhäusern u. dgl.Greenhouses and like.

Die vorliegende Erfindung betrifft eine Bewässerungsanlage für Hallenböden von Reithallen, Treibhäusern u. dgl.The present invention relates to an irrigation system for hall floors of riding halls, greenhouses and. like.

Bewässerungsanlagen der vorgenannten Art bestehen in der Re¬ gel aus einer Mehrzahl paralleler, im Dachbereich der be¬ treffenden Halle fest installierter Sprührohre.Irrigation systems of the aforementioned type generally consist of a plurality of parallel spray pipes permanently installed in the roof area of the hall in question.

Diese Anordnungen sind aber sehr unvollkommen und vermögen weder ausreichend noch schnell genug den Hallenboden zu be¬ wässern, da infolge begrenztem Wasserdruck nicht an allen Stellen der Rohre gleiche Waεsermengen austreten können. Dies führt zudem zu Sprühregen, welcher die Luftfeuchtigkeit unerwünscht ansteigen lässt.However, these arrangements are very imperfect and are unable to water the hall floor sufficiently or quickly enough, since, due to limited water pressure, the same amounts of water cannot escape at all points on the pipes. This also leads to drizzle, which affects the humidity increases undesirably.

Um dem zu begegnen, werden bei einer anderen Ausführungsform an parallelen Seitenwänden der Halle Pendelrohre angeordnet, die einen Wasserstrahl mit hohem Druck auswerfen, wobei sich die hinundher bewegten Wasserstrahlen schneiden.To counter this, in another embodiment, pendulum tubes are arranged on parallel side walls of the hall, which eject a water jet with high pressure, the water jets moving back and forth intersecting.

Solche Anordnungen führen zum bekannten Effekt der "Ueber- schwemmuπg" in der Mitte des Hallenbodens, wogegen randnahe Bereiche des Hallenbodens trocken bleiben.Such arrangements lead to the known effect of "flooding" in the middle of the hall floor, whereas areas of the hall floor near the edge remain dry.

Aufgabe der vorliegenden Erfindung ist nun die Schaffung ei¬ ner Bewässerungsanlage für Hallenböden von insbesondere Reithallen, aber auch Tennishallen, Treibhäuser u. dgl., welche bei geringstem Wasserverbrauch und minimalstem Zeit¬ aufwand eine optimale und an jeder Stelle absolut gleich intensive Bewässerung des Hallenbodens erlaubt.The object of the present invention is now to create an irrigation system for hall floors, in particular riding halls, but also tennis halls, greenhouses and the like. Like., Which allows an optimal and absolutely equally intensive irrigation of the hall floor with the lowest water consumption and the minimum time expenditure.

Dies wird erfindungsgemass erreicht durch wenigstens ein, an parallelen Seitenwänden der Halle hin- und herbewegbar ab¬ gestütztes, an einer Mehrzahl gegen den Hallenboden gerich¬ tete Douchedüsen (11) ausmündendes Düsenrohr (10), das an seiner offenen Seite an einer Pumpe (12) angeschlossen ist, die saugseitig über ein Saugrohr (13) mit einem offenen, sich parallel des Verschiebungsweges erstreckenden wasser- gespeisten Kanal (14) in Strömungsverbindung steht.According to the invention, this is achieved by at least one nozzle pipe (10) supported on a plurality of shower nozzles (11) which can be moved back and forth on parallel side walls of the hall and which opens on a pump (12 ) is connected, the suction side via a suction pipe (13) with an open, parallel to the displacement path extending water fed channel (14) is in flow connection.

Durch diese Massnah en gelingt nun eine flächendeckende und absolut gleichmässige Bewässerung des Hallenbodens, was noch unterstützt wird durch die gleichbleibende Länge der Druckleitung für das Wasser und den gleichbleibenden Strömungsdruck, indem das Wasser aus einem offenen wasser¬ gespeisten Kanal angesaugt und nicht direkt aus dem Wasser¬ versorgungsnetz eingespeist wird.Through these measures, a comprehensive and absolutely uniform irrigation of the hall floor is now possible, which is further supported by the constant length of the pressure line for the water and the constant flow pressure, in that the water is drawn in from an open water-fed channel and not directly from the water ¬ supply network is fed.

Weiter ist erfindungswesentlich, dass das Düsenrohr an ei¬ nem Spannseil aufgehängt ist, das sich von einer parallelen Seitenwand zur anderen erstreckt und an, in Schienenprofi¬ len geführten Laufkatzen abgespannt ist, womit das Düsenrohr bei seiner Verschiebung völlig entlastet ist.It is also essential to the invention that the nozzle tube is suspended from a tensioning rope which extends from one parallel side wall to the other and is tensioned on trolleys guided in rail profiles, so that the nozzle tube is completely relieved when it is moved.

Bei einer bevorzugten Ausführungsform können die beiden Laufkatzen für das Katzfahren je im Zug einer umlaufenden Antriebskette angeordnet sein und ferner, die beiden An¬ triebsketten über eine gemeinsame Kettenradwelle motorisch oder synchron je motorisch antreibbar sein.In a preferred embodiment, the two trolleys for trolley travel can each be arranged in the train of a rotating drive chain and, furthermore, the two drive chains can be driven in a motorized or synchronous manner via a common sprocket shaft.

Weiter ist es von Vorteil, wenn eine der Laufkatzen die Pumpe mit dem Saugrohr trägt. Ferner können bei einer weiteren bevorzugten Ausführungs¬ form dem, mit dem Saugrohr in StrömungsVerbindung stehen¬ den wassergespeisten Kanal ein, an eine Wasserversorgungs¬ leitung anschliessbarer Ueberströmbehälter zugeordnet sein, dessen Ueberlaufoffnung am wassergespeisten Kanal ausmündet, und ferner kann in der Wasserversorgungsleitung ein Schwim¬ merventil angeordnet sein, dessen Schwimmer im wasserge- speisten Kanal eintaucht.It is also advantageous if one of the trolleys carries the pump with the suction pipe. Furthermore, in a further preferred embodiment, the water-fed channel, which is in flow connection with the suction pipe, can be assigned an overflow tank which can be connected to a water supply line, the overflow opening of which opens at the water-fed channel, and a float valve can also be located in the water supply line be arranged, the float of which is immersed in the water-fed channel.

Eine beispielsweise Ausführungsform des Erfindungsgegen¬ standes ist nachfolgend anhand der Zeichnung, welche in schaubildartiger sche atischer Darstellung eine erfindungs- gemässe Bewässerungsanlage zeigt, näher erläutert.An example embodiment of the subject matter of the invention is explained in more detail below with reference to the drawing, which shows an irrigation system according to the invention in a diagrammatic representation.

Die dargestellte Bewässerungsanlage sei für den Hallenboden 1 einer Reithalle vorgesehen.The irrigation system shown is intended for hall floor 1 of a riding hall.

Hierfür ist ein, an parallelen Seitenwänden der nicht näher gezeigten Halle hin- und herbewegbar abgestütztes, an einer Mehrzahl gegen den Hallenboden 1 gerichtete Douchedüsen 11 ausmündendes Düsenrohr 10 vorgesehen, das an seiner offenen Seite an einer Pumpe 12 angeschlossen ist, die saugseitig über ein Saugrohr 13 mit einem offenen, sich parallel des Verschiebungsweges erstreckenden wassergespeisten Kanal 1 in Strömungsverbindung steht. Hierbei ist das Düsenrohr 10 an einem Spannseil 15 aufge¬ hängt, das sich von einer parallelen Seitenwand der Halle zur anderen erstreckt und an, in Schienenprofilen 16 geführ¬ ten Laufkatzen 20 und 21 abgespannt ist.For this purpose, a nozzle pipe 10 is provided, which is supported on the parallel side walls of the hall (not shown in more detail) and which opens out at a plurality of shower nozzles 11 directed towards the hall floor 1 and which is connected on its open side to a pump 12 which is on the suction side via a suction pipe 13 is in flow connection with an open water-fed channel 1 which extends parallel to the displacement path. Here, the nozzle tube 10 is suspended from a tensioning cable 15 which extends from one parallel side wall of the hall to the other and is tensioned on trolleys 20 and 21 guided in rail profiles 16.

Die Laufkatzen 20 und 21 können ein beliebiges bekanntes Laufwerk aufweisen, denen dann das Schienenprofil 16 anzu¬ passen ist. Dies bedarf keiner näheren Erläuterung, da nicht erfindungswesentlich.The trolleys 20 and 21 can have any known drive, to which the rail profile 16 is then to be adapted. This requires no further explanation, since it is not essential to the invention.

Für das Katzfahren sind beide Laufkatzen 20 und 21 in eben¬ falls bekannter Weise je im Zug einer umlaufenden, um Ket¬ tenräder 19 geführten Antriebskette 18 angeordnet. Hierbei sind die beiden Antriebsketten 18 über eine gemeinsame Ket¬ tenradwelle 22 motorisch, hier durch Katzmotor 17, oder synchron je motorisch antreibbar.For trolley travel, both trolleys 20 and 21 are each arranged in the train in a manner known per train of a rotating drive chain 18 guided around chain wheels 19. Here, the two drive chains 18 can be driven by a common sprocket shaft 22 by motor, here by trolley motor 17, or synchronously by motor.

Die eine Laufkatze 20 trägt die genannte Pumpe 12 mit dem Saugrohr 13, in das vorzugsweise ein Strömungsventil 29 ein¬ geschaltet ist.One trolley 20 carries the aforementioned pump 12 with the suction pipe 13, into which a flow valve 29 is preferably connected.

Dem, mit dem Saugrohr 13 in Strömungsverbindung stehenden wassergespeisten Kanal 14 ist nun vorzugsweise etwa mittig der Kanalerstreckung ein, an eine Wasserversorgungsleitung 26 anschliessbarer Ueberstrombehalter 24 zugeordnet. Dieser Ueberstrombehalter 24 weist eine Ueberlaufoffnung 25 auf, die am wassergespeisten Kanal 14 ausmündet.The water-fed channel 14, which is in flow connection with the suction pipe 13, is now preferably assigned an overcurrent holder 24 that can be connected to a water supply line 26, approximately in the middle of the channel extension. This Overflow holder 24 has an overflow opening 25 which opens out at the water-fed channel 14.

Auf diese Weise wird eine praktisch Strömungsdruckfreie, gleichmässige Nachfüllung des wassergespeisten Kanals 14 erreicht, so dass die Pumpe 12 an jeder Stelle des Kanals 14 über das Saugrohr 13 immer gleiche Wassermengen ansaugen und in das Düsenrohr 10 einspeisen kann. Ein Schwimmerven¬ til 27 in der Wasserversorgungsleitung 26 mit in den Kanal 14 eintauchendem Schwimmer 28 sorgt dabei für eine Niveau¬ regelung des Wassers im wassergespeisten Kanal 1 .In this way, a practically flow pressure-free, uniform refilling of the water-fed channel 14 is achieved, so that the pump 12 can always suck in the same amounts of water at every point of the channel 14 and feed it into the nozzle tube 10. A float valve 27 in the water supply line 26 with a float 28 immersed in the channel 14 ensures a level control of the water in the water-fed channel 1.

Den Weg der Laufkatzen 20 und 21 begrenzende Endschalter 2 sowie Katzmotor 17, Pumpe 12, Schwimmerventil 27 und Strö- mungsventil 29 sind mit einer gemeinsamen Steuerschaltung 3 verbunden, welche neben Ein-Aus-Schaltfunktionen die Wie¬ derholfrequenz der Hin- und Rückbewegung der Laufkatzen 20, 21 u. dgl. steuert. Die Stromversorgung sowie die Steuer¬ verbindungen können über Schleppleitungen oder Stromschie¬ nen erfolgen.Limit switches 2, as well as trolley motor 17, pump 12, float valve 27 and flow valve 29, which limit the path of the trolleys 20 and 21, are connected to a common control circuit 3 which, in addition to on-off switching functions, the repetition frequency of the back and forth movement of the trolleys 20, 21 u. Controls. The power supply and the control connections can take place via trailing lines or busbars.

Aus dem Vorbeschriebenen ergibt sich somit eine Bewässe¬ rungsanlage, die trotz einfachster Konzeption eine optima¬ le Bewässerung von Hallenböden in kürzester Zeit erlaubt, wobei sich die erfindungsgemässe Bewässerungsanlage insbe- sondere nach dem Baukastenprinzip erstellen lässt und somit für jede Hallengrösse geeignet ist. An irrigation system results from the above, which, despite the simplest conception, permits optimal irrigation of hall floors in the shortest possible time, the irrigation system according to the invention being particularly can be created according to the modular principle and is therefore suitable for any size of hall.
