Description
Peristaltischer WanderfeldantriebPeristaltic traveling field drive
Diese trfindug macht es sich zu Aufgabe,ein entsprechend geformtes Gebilde in einem fließ- oder gleitfähigen Milieu voranzutreiben.This trfindug makes it its task to create a suitably shaped To advance structures in a flowable or slippery environment.
Dieses voranzutreibende Gebilde ist von einer elastischen Membran,dem umhüllenden Mantel,umgeben'der durch ein verformbares Medium auf einer gewissen Distanz zur festen Oberfläche des Gebildes gehalten wird,den Spaltraum bildend Zur gewünschten Fortbewegung befinden sich orthogonal zur Bewegungsrichtung auf der gesam ten dafür geeigneten festen,also inneren'Oberfläche elektr. Feldinagnetring anordnungen'die auf magnetisierbare PartikeL in dem umhüllenden Mantel einzuwirken vermögen.This structure to be driven forward is of an elastic membrane, the enveloping jacket, surrounded by a deformable medium on a certain Distance to the solid surface of the structure is kept, forming the gap desired locomotion are orthogonal to the direction of movement on the entire solid, i.e. inner 'surface suitable for this purpose, electr. Field information ring arrangements'that act on magnetizable particles in the enveloping jacket capital.
Werden diese Magnete in einer sinnvollen zeitlichen Folge vom vorderen Ende zum rückwärtigen geschaltetwird das das Gebilde umgebende Medium so verdrängt,daß es eine Vortriebskraft erfährt.Will these magnets move from the front in a meaningful time sequence When switched from the end to the rear, the medium surrounding the structure is displaced in such a way that it experiences a propulsive force.
Der Mantel führt mit einer Serie von wechselnden Einschnürungen und Ausbuchtungen eine peristaltische Bewegung aus.The coat leads with a series of alternating constrictions and Bulges from a peristaltic movement.
Die Anwendung dieses Antriebes kann in Gebilden erheblicher Größenordnungsunterschiede praktiziert werden.The use of this drive can vary considerably in size be practiced.
Zwei wesentliche Wirkungsweisen seien an Beispielen erklärt, wobei Uberschneidungen zudem möglich sind.Two main modes of action are explained using examples, with Overlaps are also possible.
Statischer oder gasiestatischer Vortrieb Hierbei wirkt die Peristaltik auf mehr oder minder starre oder nachgiebige Innenwände schlauchiger Natur ein.Static or gas static propulsion This is where peristalsis works on more or less rigid or flexible inner walls of a tubular nature.
Ein bedeutender Anwendungsfall sind die langgestreckten Hohlorgane bei Mensch oder Tier. The elongated hollow organs are an important application in humans or animals.
In der Verwendung als Darmsonde z.B. erhält der Wanderfel&-antriebskopf Öffnungen für die Spülflüssigkeit,Absaugung, ggf. Endoskop und die elektrische Zuleitung mit den entsprechenden Verbindungsschläuchen.When used as an intestinal probe, for example, the Wanderfel & -antriebskopf Openings for the rinsing liquid, suction, possibly endoscope and the electrical supply line with the corresponding connection hoses.
In einer besonders interessanten Ausführungsform wird der Spaltraum wird der Spaltraum als Aktivpumpe zum Abtransport des Spülgut genutzt.Die Spülflüssigkeit entströmt druckgeregelt am vorderen Ende und tritt mit dem Spülgut befrachtet über geeignete Öffnugen in den Spaltraum ein,wird dort zum hinteren Ende gepumpt und gelangt in den Absaugschlauch.Das Mundstück ist lippenartig auszubilden,um dem Ergreifen und Zerkleiner verhärteter Boli Unterstützung zu gewahren.»ieser aktive Transport ist Methode der Wahl zu einer sicheren Entleerung mit einer geringen Belastung.In a particularly interesting embodiment, the gap is the gap is used as an active pump to remove the items to be washed flows out at the front end under pressure control and passes over with the items to be washed suitable openings in the gap, there is pumped to the rear end and The mouthpiece has to be designed like a lip so that it can be grasped and to provide assistance to crushers of hardened boluses. ”This active transport is the method of choice for safe and low-impact emptying.
Die Antriebseinheit kann selbst aus recht elstische Material bestehen und so lang sein,daß die Kräfte je Flächeneinheit zur Gewebeschonung außerordentlich klein gehalten werden können. The drive unit itself can consist of quite elastic material and be so long that the forces per unit area for tissue protection are extraordinary can be kept small.
Die Steuerung ist mitten einfacher mikroelektronischer Bauelemente mit geringem Volumen zu realisieren.und mit äußerst dünnen Anschlußleitungen nach außen zu verbinden, b) Dynamischer Vortrieb Hierbei erfolgt der Antrieb in fließfähigen Medien'deren Dichte zur Kräfteeinleitung ausreichend hoch sein,so daß im allgemeinen nur Flüssigkeite.,insbesondere Wasser in Frage koma8.The control is in the middle of simple microelectronic components to be realized with a small volume and with extremely thin connecting cables to connect outside, b) Dynamic propulsion This is where the Drive in flowable media whose density is sufficiently high for the introduction of forces so that in general only liquids, especially water, come into question.
Als wesentlicher Anwendungsfall ist der Antrieb Unterwasserfahrzeugen zu sehen,wie U-Boote,Torpedos u.ä.The main application is the propulsion of underwater vehicles to see how submarines, torpedoes, etc.
Der peristaltische Wancierfeldantrieb erweist sich für diesen Anwendungfall als geradezu ideal:Annähernd die gesamte eingetauchte Oberfläche ist den Vortriebszweck zuordenbar - während der Marschgeschwiadigkeit ist der Schlupf zwischen dem umströmenden Wasser und der peristaltischen Oberflächenbewegung sehr klein.The peristaltic Wancierfeld drive proves itself for this application as ideal: Almost the entire submerged surface is the purpose of the tunneling assignable - during the march speed is the slip between the flowing around Water and the peristaltic surface movement are very small.
Zur Beeinflußüng der Fahrtrichtung una der Lage im Raum ist die ringförmige Wicklungsanordnung in Ringsegmente aufzuteilen'die in ihrer Wirkung nach Größe und Richtung der Peristaltik separat zu schalten sind.To influence the direction of travel and the position in space, the ring-shaped one To divide the winding arrangement into ring segments in terms of size and effect The direction of the peristalsis must be switched separately.
Mit dem Fehlen von Schraubengeräuschen und minimierten Strömungs#eräuschen ist eine Passivortung unmöglich.Noise with the absence of screw noise and minimized flow # passive location is impossible.
Darüberhinaus ist durch die systembedingte weiche umhüllende Oberfläche mit den vielen Ein- und Ausbuchtungen eine aktive Ortung gleichermaßen nicht möglich.In addition, it is due to the soft, enveloping surface inherent in the system With the many indentations and bulges, active localization is equally not possible.
Zur Wirkungsgradanhebung des Antriebes ist die Außen- und Inneförderung des umhüllenden Mantels auszunutzen.To increase the efficiency of the drive, the external and internal conveyance to take advantage of the enveloping jacket.
In Fahrt richtung vorne befinden sich Einlaßöffnungen'die mit dem umgebenden Wasser kommunizieren,am hinteren Ende befindet sich eine entsprechende Auslaßdüse.Der Wanderfeldantrieb übt auf das in den Spaltraum eingeströmte Wasser eine Pumpwirkung in Rich-tung Auslaß aus,die zum Vortrieb beiträgt.In the direction of travel in front there are inlet openings with the communicate with the surrounding water; there is a corresponding one at the rear end The traveling field drive acts on the water that has flown into the gap a pumping action in the direction of the outlet, which contributes to the propulsion.
Als mögliches Ausführungsbeispiel ist eine Darmsonde Fig.1 dargestellt.An intestinal probe is shown in FIG. 1 as a possible embodiment.
Der die Feldmagnetwicklung tragende Grundkörper 1 ist ist für den Spülkanal hohlgebohrt,die Spülflüssigkeit tritt am Vorderende 3 aus und wird durch die lippenartige Vorwölbungen 3 des umhüllenden Mantels 2 in den Spaltraum 7 mit dem Spülgut beladen gefördert.The base body 1 carrying the field magnet winding is for the The flushing channel is hollow, the flushing liquid exits at the front end 3 and is passed through the lip-like protrusions 3 of the enveloping jacket 2 in the gap 7 with Loaded with the wash ware promoted.
Der Anchlußschlauch sorgt für die ZU- und Fortleitung 6 und 4 - Leerseite -The connection hose takes care of the inlet and outlet lines 6 and 4 - Blank page -
