Abstract

The water canvas has inflow square pipe made of aluminum, in which water nozzles or holes are attached on the lower surface. The water falls in a collecting tank from the lower surface. A water curtain consists of thousands drops, which are used particularly as water canvas for image projection. The aluminum profile e.g. pipe, is used for production of a water curtain or a water canvas, which consists of a wedge-shaped tapering which causes a better inflow of the ambient air at the water outlet of the nozzles. The wedge-shaped aluminum profiles have a rounded and flow optimized tapering.

Description

Es ist bekannt, das Wasserleinwände im herkömmlichen Sinne, aus einem vierkant Aluminiumrohr (oder anderem Materialen) besteht, auf der an der Unterseite Wasserdüsen oder Löcher angebracht sind, aus denen Wasser in ein Auffangbecken fällt. Dieser Wasservorhang besteht aus vielen tausend Tropfen, welche für Bildprojektionen verwendet wird.It is known, the water screens in the conventional Meaning, from a square aluminum tube (or other materials) exists, on which at the bottom water nozzles or holes are attached, from which Water falls into a catch basin. This Water curtain consists of many thousand drops, which are used for image projections is used.

Um eine möglichst gute Bildqualität zu erreichen, ist ein möglichst homogenes Fallen der Wassertropfen nötig.Around one possible good picture quality To achieve one is as possible homogeneous falling of the water drops necessary.

Dabei fällt jedoch auf, daß bei der Verwendung von herkömmlichen „Standard" vierkant Rohren sich eine nachteilige Aufweitung des Wasservorhangs ergibt.there falls, however on that at the use of conventional "standard" square tubes themselves an adverse expansion of the water curtain results.

Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, das durch diese nachteilige Aufweitung des Wasservorhangs die Wassertropfen einen sehr starken Luftsog beim Austritt aus den Wasserdüsen erzeugen und durch die „Standard" Profile das Anströmen der Luft nicht optimal gewährleistet ist und die Bildqualität darunter leidet.Of the The invention defined in claim 1 is based on the problem the water droplets due to this disadvantageous widening of the water curtain produce a very strong air suction when exiting the water nozzles and by the "standard" profiles the flow of the Air not optimally guaranteed is and the picture quality suffer from.

Dieses Problem wird durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.This Problem is solved by the features listed in claim 1 solved.

Die Verwendung eines keilförmig zulaufenden Profils, soll eine bessere Zuströmung der Umgebungsluft am Wasseraustritt der Düsen ermöglichen.The Use of a wedge-shaped tapered profile, a better inflow of ambient air at the water outlet the nozzles enable.

Dadurch werden die Wassertropfen und kleinste Spritzwassertropfen weniger abgelenkt und es ergibt sich eine verbesserte Falleigenschaft der Tropfen.Thereby the drops of water and the smallest splash drops are less deflected and there is an improved drop property of the drops.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass durch die „dünnere" Wasserleinwand eine schärfere und wesentlich verbesserte Bildqualität entsteht.The particular advantages of the invention are that through the "thinner" water screen a sharper and much improved picture quality is created.

Eine vorteilhafte Ausgestaltung der Erfindung ist im Patenanspruch 2 angegeben. Die Weiterbildung nach Patenanspruch 2 ermöglicht es, dass die Luft an gerundeten/strömungsoptimierteren Verjüngungen noch besser anströmen kann und dadurch die Bildqualität des Wasservorhangs bei Projektionen jeglicher Art erhöht wird.A advantageous embodiment of the invention is in claim 2 specified. The training according to claim 2 allows that the air on rounded / flow-optimized tapers flow even better can and thereby the picture quality the water curtain is increased in projections of any kind.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben.One embodiment The invention is illustrated in the drawing and will be described below described in more detail.

1. Stand der Technik: (Zeichnung 1) 1. Prior Art: (Drawing 1)

In einem vierkant Aluminiumrohren sind auf der Unterseite Wasserdüsen oder Löcher angebracht, aus denen Wasser in ein Auffangbecken fällt. Dieser Wasservorhang besteht aus vielen tausenden Tropfen, welche für Bildprojektionen als „Wasserleinwand" verwendet wird.In A square aluminum pipes are on the bottom water nozzles or holes attached, from which water falls into a catch basin. This Water curtain consists of many thousands of drops, which for image projections used as a "water screen".

Um eine möglichst gute Bildqualität zu erreichen, ist ein möglichst homogenes Fallen der Wassertropfen nötig. Durch die Verwendung von Standard vierkant Rohren ist eine nachteilige Aufweitung des Wasservorhangs gegeben. Die Wassertropfen erzeugen einen starken Luftsog beim Austritt aus den Wasserdüsen. Durch „Standard" Profile ist das Anströmen der Luft nicht optimal gewährleistet.Around one possible good picture quality To achieve one is as possible homogeneous falling of the water drops necessary. By the use of Standard square tubing is a detrimental widening of the water curtain given. The drops of water create a strong air suction on exit from the water nozzles. By "standard" profiles that is Provide flow the air is not optimally guaranteed.

2. Zu Zeichnung 2:2. To drawing 2:

Die Verwendung eines Keilförmig zulaufenden Profils ermöglicht eine bessere Zuströmung der Umgebungsluft am Wasseraustritt der Düsen. Dadurch werden die Wassertropfen und kleinste Spritzwassertropfen weniger abgelenkt und es ergibt sich eine verbesserte Falleigenschaft der Tropfen. Durch die "dünnere" Wasserleinwand ergibt sich eine schärfere Bildqualität.The Use of a wedge tapered profile allows a better inflow the ambient air at the water outlet of the nozzles. This will make the drops of water and smallest splash drops less distracted and it yields an improved drop characteristic of the drops. The "thinner" water screen results in a sharper image quality.

3. Zu Zeichnung 3:3. To drawing 3:

Die Luft kann an geraden (Patentanspruch 1) oder gerundeten/strömungsoptimierten (Patenanspruch 2) Verjüngungen verbessert anströmen.The Air can on straight (claim 1) or rounded / flow-optimized (Claim 2) Rejuvenations improves flow.
