Description

Die Erfindung betrifft eine Vorrichtung zur Außenreinigung von Schiffsrümpfen mit mindestens einer rotierend antreibbaren, in einem Rahmengestell drehbar gelagerten Reinigungswalze, die sich zumindest teilweise unter der Wasseroberfläche eines Gewässers befindet.The invention relates to a device for the exterior cleaning of ship hulls with at least one rotating drivable, rotatably mounted in a frame cleaning roller, which is at least partially below the water surface of a body of water.

Die Rümpfe von Schiffen und Jachten werden unterhalb oder im Bereich der Wasserlinie je nach Art des Gewässers im Laufe der Zeit von einer Vielzahl von Lebewesen wie Algen, Muscheln, Korallen und dergleichen besiedelt. Dadurch kann u. U. das Rumpfmaterial in Mitleidenschaft gezogen werden, in jedem Falle wird jedoch der hydrodynamische Widerstand des Schiffsrumpfes verschlechtert, so daß die Fahreigenschaften des Schiffes beeinträchtigt werden bzw. bei motorgetriebenen Schiffen ein erhöhter Kraftstoffverbrauch die Folge ist.The hulls of ships and yachts are populated below or near the waterline depending on the nature of the water over time by a variety of organisms such as algae, shells, corals and the like. This can u. However, in any case, the hydrodynamic resistance of the hull is deteriorated so that the driving characteristics of the vessel are affected or in motorized vessels increased fuel consumption is the result.

Aus diesem Grunde wurden die Schiffe bisher etwa einmal jährlich mittels eines Hebezeuges aus dem Wasser gehoben und die angewachsenen Beläge manuell entfernt.For this reason, the ships have been lifted about once a year by means of a hoist out of the water and removed the grown coverings manually.

Um die Besiedelung des Schiffsrumpfes mit lebenden Organismen, einzuschränken bzw. zu verhindern, werden die Schiffsrümpfe nach dem Stand der Technik auch regelmäßig mit einer aus stark toxischen Substanzen bestehenden sogenannten "Antifoul"-Beschichtung versehen, deren inhibierende Wirkung jedoch verhältnismäßig rasch nachläßt, da die verwendeten Substanzen, um auf die Organismen toxisch wirken zu können, immer auch zumindest geringfügig wasserlöslich sein müssen. Die Verwendung derartiger toxischer Substanzen ist aus Umweltschutzgründen problematisch.In order to limit or prevent the colonization of the hull with living organisms, the hulls according to the prior art are also regularly provided with a so-called "antifouling" coating consisting of highly toxic substances, but their inhibiting effect diminishes relatively rapidly, since the used substances in order to be toxic to the organisms, must always be at least slightly soluble in water. The use of such toxic substances is problematic for environmental reasons.

Die notwendige manuelle Reinigung der Schiffsrümpfe ist rela tiv zeitaufwendig und verursacht erhebliche Kosten. Auch kann sie in der Regel nur an teuren Liegeplätzen ausgeführt werden, wo entsprechende Hebekräne zur Verfügung stehen.The necessary manual cleaning of the hulls is rela tively time-consuming and causes considerable costs. Also, it can usually only be performed on expensive moorings where appropriate lifting cranes are available.

Derartige Vorrichtungen sind beispielsweise aus der DE 296 07 426 und der US 4,236,477 bekannt. Sämtliche dieser aus dem Stand der Technik bekannten Vorrichtungen weisen jeweils starre walzenachsen auf, die drehbar angetrieben werden. Ein Schiffsrumpf ist bekanntermaßen gekrümmt ausgebildet, so dass jede Walzenachse nur in einem bestimmten Linearbereich vollflächig anliegt, nicht aber entlang ihrer gesamten Walzenachsen. Demzufolge wird der optimale Anpress- und Reinigungsdruck nur in einem bestimmten Walzenabschnitt bewirkt.Such devices are known for example from DE 296 07 426 and US 4,236,477. All of these known from the prior art devices each have rigid roller axes, which are rotatably driven. A ship's hull is known to be curved, so that each roll axis is fully applied only in a certain linear range, but not along their entire roll axes. Consequently, the optimum pressure and cleaning pressure is effected only in a specific roller section.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Reinigungsvorrichtung derart weiterzuentwickeln, dass die Reinigung besser durchführbar ist.The invention has for its object to further develop a generic cleaning device such that the cleaning is easier to carry out.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Reinigungswalze einen elastisch deformierbaren und an die Form des Schiffsrumpfes anpassbaren Kern aufweist, an dem einzelne Bürstenelemente drehfest angeordnet sind, die auf ihrer Umfangsfläche bürstenförmige, sich in radialer Richtung erstrekkende Reinigungskörper aufweisen.This object is achieved in that the cleaning roller has an elastically deformable and adaptable to the shape of the hull core, are rotatably disposed on the individual brush elements having on its peripheral surface brush-shaped, in the radial direction erstrekkende cleaning body.

Um auf alle Bereiche des Schiffsrumpfes einen gleichmäßigen Druck ausüben zu können, aber auch um unterschiedliche Schiffsrümpfe mit derselben Vorrichtung reinigen zu können, sind die Walzenachsen der Reinigungswalzen flexibel an die Rumpfform anpassbar ausgebildet. Dazu können die Achsen beispielsweise segmentweise aufgebaut sein, wobei die Segmente zum Beispiel über Federelemente miteinander verbunden sind. Auch Achsenkörper aus elastischem Kunststoff- oder Gummimaterialien sind hierzu geeignet.In order to be able to exert uniform pressure on all areas of the hull, but also to be able to clean different hulls with the same device, the roller axes of the cleaning rollers are flexibly adapted to the hull shape. For this purpose, the axes may for example be constructed in segments, the segments are connected to each other, for example via spring elements. Also axle body made of elastic plastic or rubber materials are suitable for this purpose.

Die Oberfläche der Reinigungswalze ist vorzugsweise so ausgebildet, dass sie in rotierendem Zustand zwar aggressiv auf die aufwachsenden Schichten aus lebenden Organismen einwirkt, jedoch keine Gefahr einer Beschädigung der üblicherweise aus Glasfaser-verstärktem Kunststoff GFK hergestellten Rümpfe besteht. In Frage kommen insbesondere Bürstenwalzen, Schlaufenwalzen, Walzen mit aufgerauhten Oberflächen oder mit schleifenden oder schmirgelnden Substanzen belegte Walzen. Zwar ist im Prinzip die Reinigung eines gesamten Schiffsrumpfes mit einer Reinigungswalze möglich, vorzugsweise sind jedoch ein oder mehrere Walzenpaare vorgesehen, deren Einzelwalzen jeweils auf der Steuerbord- bzw. Backbordseite angeordnet sind. Dadurch kann die erforderliche Reinigungszeit drastisch gesenkt werden.The surface of the cleaning roller is preferably designed so that it acts aggressively on the growing layers of living organisms in the rotating state, but there is no risk of damage to the hulls usually made of glass fiber reinforced plastic GRP. In particular, brush rolls, loop rolls, rolls with roughened surfaces or rolls coated with abrasive substances may be considered. Although in principle the cleaning of an entire hull with a cleaning roller is possible, but preferably one or more pairs of rollers are provided, the individual rollers are arranged in each case on the starboard side or port side. As a result, the required cleaning time can be drastically reduced.

Das Gestell zum Tragen bzw. zur Aufnahme der Reinigungswalzen kann von Schwimmkörpern getragen werden, ist jedoch vorzugsweise ortsfest im Wasser beispielsweise mit Hilfe von Bodenankern positioniert. Das Schiff wird dann z. B. mit Hilfe einer Ankerwinde oder dergleichen durch die Reinigungsanlage gezogen, wobei die Vorschubgeschwindigkeit auf die Dicke bzw. Art und Weise der Verschmutzungen und Bewüchse angepaßt werden kann.The frame for carrying or for receiving the cleaning rollers can be carried by floats, but is preferably stationary in the water, for example, with the help of ground anchors positioned. The ship is then z. B. by means of an anchor winch or the like pulled by the cleaning system, the feed rate can be adapted to the thickness or manner of contamination and Bewüchse.

Andererseits ist es auch möglich, das Schiff ortsfest zu verankern und die Reinigungswalzen im Gestell in Längsrichtung des Schiffes verfahrbar anzuordnen.On the other hand, it is also possible to anchor the ship stationary and to arrange the cleaning rollers in the frame in the longitudinal direction of the vessel movable.

Zur Anpassung an unterschiedliche Schiffsrümpfe ist es weiterhin vorteilhaft, die Reinigungswalzen im Gestell in Richtung zum Schiffsrumpf verfahren zu können. Aus dem gleichen Grunde sollte der Neigungswinkel der Walzenkörper bzw. Walzenachsen zur Senkrechten einstellbar sein.To adapt to different hulls, it is also advantageous to be able to move the cleaning rollers in the frame in the direction of the ship's hull. For the same reason, the angle of inclination of the roll body or roll axes should be adjustable to the vertical.

Die Antriebsmotoren bzw. die Motoren zum Verstellen der Reini gungswalzen sind vorzugsweise oberhalb der Wasseroberfläche angeordnet und können z. B. von dem Gestell für die Reinigungswalzen getragen werden. Sie sind zum Antrieb der Reinigungswalzen mit diesen mit Hilfe der üblichen Trieborgane wie Zahnriemen, Kegelradgetriebe oder dergleichen verbunden, so daß die Funktionsfähigkeit der Antriebe bzw. Lager und sonstiger beweglicher Teile unter Wasser gewährleistet ist.The drive motors or motors for adjusting the cleaning supply rollers are preferably arranged above the water surface and can, for. B. are supported by the frame for the cleaning rollers. They are connected to drive the cleaning rollers with these with the help of the usual drive elements such as timing belt, bevel gear or the like, so that the operability of the drives or bearings and other moving parts under water guaranteed is.

Die Antriebs- bzw. Stellmotore sind vorzugsweise als gekapselte Elektromotore ausgebildet. Ebenso können hydraulische oder pneumatische Motoren eingesetzt werden. Bei automatisch arbeitenden Reinigungsanlagen können sie beispielsweise mit Hilfe von Sensoren, die auf die Größe, die Form und Position des Schiffsrumpfes ansprechen, geregelt bzw. gesteuert sein.The drive or servo motors are preferably designed as encapsulated electric motors. Likewise, hydraulic or pneumatic motors can be used. In automatic cleaning systems, for example, they can be controlled by means of sensors that respond to the size, shape and position of the ship's hull.

Neben Reinigungswalzen können auch umlaufende Reinigungsbänder verwendet werden, die mit Hilfe entsprechender Antriebe gegen den Schiffsrumpf geführt werden.In addition to cleaning rollers and rotating cleaning belts can be used, which are guided by means of appropriate drives against the hull.
