Description

Die Erfindung betrifft eine Vorrichtung zum Suchen und Räumen von Fremdkörpern und Hindernissen im Sohlenbereich von schiffbaren Gewässern.The invention relates to a device for searching and clearing foreign bodies and obstacles in the sole area of navigable waters.

Um einen einwandfreien Schiffsverkehr zu gewähr­leisten, müssen schiffbare Gewässer frei von Fremdkörpern und Hindernissen gehalten werden. Es ist bekannt, die Fremdkörper und Hindernisse von einem Schiff aus mit Stangen aufzuspüren und deren Positionen mit Bojen oder dergleichen zu bezeichnen. Besonders ausgebildete Räumschuten fahren dann jeweils zu den bezeichneten Stellen und entfernen das Hindernis oder den Fremdkörper. Diese Vorgehensweise ist sehr umständlich und zeitaufwendig und die Effektivität der Suche ist gering.In order to guarantee perfect shipping traffic, navigable waters must be kept free of foreign objects and obstacles. It is known to detect the foreign bodies and obstacles from a ship with rods and to mark their positions with buoys or the like. Specially trained clearing barges then drive to the designated points and remove the obstacle or the foreign body. This procedure is very cumbersome and time-consuming and the effectiveness of the search is low.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum Suchen und Räumen von Fremdkörpern und Hindernissen im Sohlenbereich von schiffbaren Gewässern zur Verfügung zu stellen, mit der ein systematisches Absuchen der Gewässer mit guter Genauigkeit bei relativ geringem Zeitaufwand und sofortiges Wegräumen der Fremdkörper möglich ist, wobei eine gute Manövrierfähigkeit der Vorrichtung gewähr­leistet sein soll.The invention is therefore based on the object of providing a device for locating and clearing foreign bodies and obstacles in the sole region of navigable waters, with which a systematic search of the bodies of water with good accuracy is possible with relatively little expenditure of time and immediate clearing away of the foreign bodies, a good maneuverability of the device should be ensured.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Hauptanspruchs in Verbindung mit den Merkmalen des Ober­begriffs gelöst.This object is achieved according to the invention by the characterizing features of the main claim in conjunction with the features of the preamble.

Dadurch, daß die Vorrichtung einen langge­strecken Schwimmkörper aufweist, über dessen Längsseite sich ein in der Höhe verstellbarer Gelenkrahmen zum Suchen der Fremdkörper erstreckt, und daß der Schwimmkörper mit An­trieben versehen ist, die eine Querfahrt ge­statten, kann das Gewässer systematisch in nur wenigen Spuren abgesucht werden. Auf dem Schwimmkörper ist eine Lade- und Greifer­einrichtung befestigt, so daß von dem Gelenk­rahmen aufgespürte Gegenstände sofort aus der Fahrrinne entfernt werden können.Characterized in that the device has an elongated floating body, over the longitudinal side of which a height-adjustable articulated frame extends to search for the foreign bodies, and that the floating body is provided with drives which permit a transverse travel, the water can be searched systematically in only a few traces . A loading and gripping device is attached to the floating body, so that objects detected by the articulated frame can be removed immediately from the fairway.

Durch die in den Unteransprüchen angegebenen Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen möglich. Durch Vorsehen einer Schleppkette, die an der anderen Längs­seite befestigt ist und in die Gewässersohle eingreifende Anker aufweist, können auch in den Gewässergrund eingeschwemmte Fremdkörper gefunden werden. Die Anordnung der Antriebe im Bug- und Heckbereich des langgestreckten Schiffs­körpers erlaubt eine gute und schnelle Manövrier­barkeit, so daß eine schnelle Veränderung von Querfahrt in Längsfahrt möglich wird.Advantageous further developments and improvements are possible through the measures specified in the subclaims. By providing a drag chain, which is attached to the other long side and has anchors engaging in the water bed, foreign bodies can also be washed into the water bed being found. The arrangement of the drives in the bow and stern area of the elongated hull allows good and quick maneuverability, so that a rapid change in transverse travel in longitudinal travel is possible.

Vorteilhaft ist, daß die Vorrichtung mit einer Ölsperre ausgerüstet ist, die an den Ecken des Schwimmkörpers befestigt werden kann, da auf diese Weise bei Bergungsmaßnahmen der Fremdkörper auslaufendes oder freiwerdendes Öl oder Treibstoff in Grenzen gehalten wird und abgebaut werden kann.It is advantageous that the device is equipped with an oil barrier, which can be attached to the corners of the floating body, since in this way the oil or fuel escaping or liberated from foreign bodies is kept within limits and can be broken down during recovery measures.

Die Erfindung ist in der Zeichnung dargestellt und wird in der nachfolgenden Beschreibung näher erläutert. Es zeigen:

  • Fig. 1 eine Aufsicht auf die erfindungs­gemäße Vorrichtung,
  • Fig. 2 einen Schnitt der erfindungsgemäßen Vorrichtung und
  • Fig. 3 eine Ansicht auf den an der Längs­seite des Schwimmkörpers befestigten Gelenkrahmen.
The invention is illustrated in the drawing and is explained in more detail in the description below. Show it:
  • 1 is a plan view of the device according to the invention,
  • Fig. 2 shows a section of the device according to the invention and
  • Fig. 3 is a view of the articulated frame attached to the long side of the floating body.

Die Vorrichtung zum Suchen und Räumen von Fremd­körpern und Hindernissen im Sohlenbereich von schiffbaren Gewässern besteht entsprechend den Fig. 1 und 2 aus einem langgestreckten Schwimmkörper mit möglichst geringem Tiefgang in Rechteckform, wobei der Bug und das Heck des Schwimmkörpers 1 etwas abgeschrägt sind. An der Längsseite des im wesentlichen quaderförmigen langgestreckten Schwimmkörpers 1 ist ein Gelenkrahmen 2 ange­ordnet, der näher in Figur 3 dargestellt ist. An dem Schwimmkörper 1 sind über seine Länge parallelliegende Gelenkführungen 3 befestigt, in denen höhenverstellbar vertikal angeordnete Stangen oder Balken 4 geführt sind. Die Stangen 4 sind an ihren der Gewässersohle 5 zugewandten Enden über in Gelenkverbindungen 6 gehaltene Balken 7 miteinander verbunden. Der Gelenkrahmen 2 wird in den Gelenkführungen 3 in seiner Tiefe derart eingestellt, daß die horizontalen Balken 7 mit geringem Abstand über die Gewässersohle 5 hinweggleiten.The device for searching and clearing foreign bodies and obstacles in the sole area of navigable waters consists, according to FIGS. 1 and 2, of an elongated floating body with the lowest possible draft in a rectangular shape, the bow and the rear of the floating body 1 being slightly beveled. On the long side of the substantially cuboid elongated Floating body 1 is an articulated frame 2, which is shown in more detail in Figure 3. On the floating body 1, parallel articulated guides 3 are fastened along its length, in which vertically adjustable rods or bars 4 are guided. The rods 4 are connected to one another at their ends facing the river bed 5 via beams 7 held in articulated connections 6. The depth of the articulated frame 2 is adjusted in the articulated guides 3 in such a way that the horizontal bars 7 slide over the water bed 5 at a short distance.

In Bug- und Heckbereich des langgestreckten Schwimmkörpers 1 sind jeweils ein Antrieb 8 vorgesehen, die nicht über den Schwimmkörper 1 herausragen, um Beschädigungen im Flachwasser zu vermeiden. Vorzugsweise schließt die Unterkante des Antriebs mit dem Boden des Schwimmkörpers 1 ab. Die Antriebe sind als Wasserstrahlantriebe ausgebildet, bei dem über ein Laufrad im Boden Wasser eingesaugt, beschleunigt und aus einem um 360° um die Vertikalachse drehbaren Krümmer als Schubstrahl wieder ausgestoßen wird. Für jeden Antrieb 8 steht ein getrenntes Antriebs­aggregat 9, über das die von einem Dieselmotor gelieferte Leistung einem den Wasserstrahlantrieb 8 antreibenden Hydraulikmotor zugeführt wird. Die Bedienung der Wasserstrahlantriebe 8 erfolgt über einen zentralen Steuerstand 10 an Deck des Schwimmkörpers 1, von dem aus die Ruderanlage und Drehzahl der Wasserstrahlantriebe gesteuert werden. Durch die Bauart und die Anordnung der Wasserstrahlantriebe 8 wird eine optimale Manövrierfähigkeit und ebenso eine konstante Querfahrt ermöglicht.A drive 8 is provided in the bow and stern area of the elongated floating body 1, which does not protrude beyond the floating body 1 in order to avoid damage in the shallow water. The lower edge of the drive preferably closes off from the bottom of the floating body 1. The drives are designed as water jet drives, in which water is sucked into the floor via an impeller, accelerated and then ejected as a thrust jet from a bend that can be rotated through 360 ° around the vertical axis. For each drive 8 there is a separate drive unit 9, via which the power supplied by a diesel engine is fed to a hydraulic motor driving the water jet drive 8. The water jet drives 8 are operated via a central control station 10 on the deck of the floating body 1, from which the rudder system and speed of the water jet drives are controlled. The design and the arrangement of the water jet drives 8 ensure optimal maneuverability and also a constant one Crossing enabled.

An der dem Gelenkrahmen 2 gegenüberliegenden Längsseite ist eine Schleppketten-Suchvorrichtung 11 befestigt, die sich über ihre gesamte Länge erstreckt. An der Schleppketten-Suchvor­richtung 11 sind in Abstand zueinander Schlepp­anker 12 angeordnet, die über den Gewässergrund geschleppt werden.A drag chain search device 11 is attached to the long side opposite the articulated frame 2 and extends over its entire length. Drag anchors 12 are arranged at a distance from one another on the drag chain search device 11 and are towed over the water bed.

Auf dem Schwimmkörper 1 ist eine Lade- und Greifereinrichtung 13 fest installiert, die als hydraulischer Ladekran mit einer relativ großen Ausladung und mit Lasthaken und Greifer ausgebildet ist. Der Antrieb erfolgt hydraulisch mittels einer Verstellpumpe von einem Wasser­strahlantriebsaggregat. Der Schwimmkörper 1 ist im Ladekranbereich durch zusätzliche Rahmen­spanten verstärkt. Im Wirkungsbereich des Ladekrans 13 ist an Deck ein nicht dargestellter Container zur Aufnahme von Bergungsgut vorge­sehen.On the floating body 1, a loading and gripping device 13 is permanently installed, which is designed as a hydraulic loading crane with a relatively large radius and with a load hook and gripper. It is driven hydraulically by means of a variable displacement pump from a water jet drive unit. The floating body 1 is reinforced in the loading crane area by additional frame frames. In the area of action of the loading crane 13, a container, not shown, is provided on the deck for receiving salvage goods.

An den Ecken des Schwimmkörpers 1 sind balken­förmige Permanentmagnete 14 befestigt, die teilweise oberhalb und teilweise unterhalb der Wasserlinie liegen. Diese Haftmagnete dienen zum Anschließen einer flexiblen Ölsperre 15, die aus einem Kunststoffband besteht. Die Enden der Ölsperre 15 sind mit Metallstäben 16 versteift, die mit den Haftmagneten 14 in magnetischen Kontakt treten.At the corners of the floating body 1, bar-shaped permanent magnets 14 are attached, which are partly above and partly below the water line. These holding magnets are used to connect a flexible oil barrier 15, which consists of a plastic band. The ends of the oil barrier 15 are stiffened with metal rods 16, which come into magnetic contact with the holding magnets 14.

Die Befeuerung der Schwimmeinheit erfolgt in vorgeschriebener Weise jeweils abhängig von der Längs- oder Querfahrt, wobei im zentralen Steuerstand 10 die Umschaltung der Befeuerung zwischen Längs- und Querfahrt vorgenommen wird. Selbstverständlich ist auch ein Unterkunfts­raum 17 auf dem Schwimmkörper 1 vorgesehen.The swimming unit is fired in the prescribed manner depending on the longitudinal or transverse travel, with the central one Control station 10 the switching of the lighting between longitudinal and transverse travel is made. Of course, an accommodation space 17 is also provided on the floating body 1.

Bei der Suche nach Fremdkörpern oder Hindernissen fährt der Schwimmkörper 1 in Querfahrt, das heißt über seine Längsseite, die zu unter­suchende Fahrrinne in nebeneinandergelegten Spuren ab. Gleitet der Gelenkrahmen über ein auf der Gewässersohle liegendes Hindernis 18, so verschiebt sich die entsprechende Stange 4 in der Gelenkführung nach oben, so daß das Vorhandensein des Fremdkörpers 18 geortet werden kann. In entsprechender Weise kann ein Fremd­körper mittels der Schleppkette 11 entdeckt werden, wenn ein oder mehrere Schleppanker 12 sich in das Hindernis verkrallen und die Fahrt stark beeinträchtigen. Über die Wasserstrahl­antriebe 8 wird der Schwimmkörper 1 anschließend in die Position gebracht, in der der Ladekran 13 mit seinem Ausleger das Hindernis greifen kann. Falls zu befürchten ist, daß der Fremdkörper Öl oder Treibstoff enthält, wird die Ölsperre 15 ausgelegt und an den Haftmagneten 14 befestigt, so daß das möglicherweise austretende Öl in vorgegebenen Grenzen bleibt und mittels Chemikalien oder dergleichen neutralisiert werden kann.When searching for foreign bodies or obstacles, the floating body 1 traverses, that is to say over its long side, the channel to be examined travels in adjacent tracks. If the articulated frame slides over an obstacle 18 lying on the water bed, the corresponding rod 4 moves upward in the articulated guide so that the presence of the foreign body 18 can be located. In a corresponding manner, a foreign body can be discovered by means of the drag chain 11 if one or more drag anchors 12 claw into the obstacle and severely impair the journey. The float 1 is then brought into the position in which the loading crane 13 with its boom can grip the obstacle via the water jet drives 8. If it is to be feared that the foreign body contains oil or fuel, the oil barrier 15 is laid out and fastened to the holding magnet 14, so that the possibly escaping oil remains within predetermined limits and can be neutralized by means of chemicals or the like.
