Abstract

The device consists of a plunger sampling pipette tube (40) and an injection unit (20,30) that can accommodate several syringes that can be emptied by the force of a motor. The volumes to be injected can be varied and the linear movement for pressing out the syringes is obtained from a rotary spindle.

Description

Der Erfindung liegt die Aufgabe zu Grunde, Transportprozesse und Abbauraten im Meeresboden zu untersuchen. Hierzu verwendet man sog. Tracer, die in bestimmten Sediment-Horizonten eingebracht werden und deren Verteilung bzw. Abbau nachfolgend untersucht wird.Of the Invention is based on the object, transport processes and degradation rates to study in the seabed. For this one uses so-called. Tracer, the be introduced into certain sediment horizons and their distribution or degradation is examined below.

Um Verfälschungen bei derartigen Untersuchungen zu vermeiden, wird der Tracer bereits unter Wasser in die Bodenprobe eingebracht und kann sich dann unter den natürlichen Bedingungen verteilen bzw. abgebaut werden.Around falsifications to avoid such studies, the tracer is already submerged in the soil sample under water and then submerged the natural one Distribute or dismantle conditions.

Bisher wurden Anlagen eingesetzt, bei denen der Tracer in das über dem Sediment befindliche Wasser gegeben bzw. auf das Sediment gestreut wurde, was nur eingeschränkte Untersuchungen der Transportprozesse erlaubte. Die bisher eingesetzten Anlagen haben auch den Nachteil, dass sie verhältnismäßig groß sind und daher nur schwer genau zu positionieren sind, was ebenfalls zu ungenauen Ergebnissen führen kann.So far were used systems in which the tracer in the above Was given to sediment or was scattered on the sediment, which is only limited Investigations of the transport processes allowed. The previously used systems also have the disadvantage that they are relatively large and therefore difficult exactly to position, which also leads to inaccurate results to lead can.

Erfindungsgemäß wird die Aufgabenstellung durch ein Gerät gelöst, welches einen Sedimentkern mittels Stechrohr (40) von der Umgebung isoliert und so gleichzeitig für den Rücktransport an die Oberfläche vorbereitet. Auf dem oberen Ende des Stechrohres ist eine zweiteilige Einspritzeinheit (20 und 30) angebracht, welche den Tracer in das Sediment einspritzt. Stechrohr und Einspritzeinheit sind fest miteinander verbunden und werden erst an der Oberfläche getrennt, um die Bodenprobe zu analysieren. Die Einspritzeinheit besteht aus einer druckfesten Elektronik- und Motoreinheit (20) und einer von Umgebungswasser durchspülten Spritzeneinheit (30). Über eine Spindel wird durch den Motor eine Anzahl von Spritzen entleert und so der Tracer in die Sedimentschicht eingebracht. Durch die Länge der Spritzen-Nadel und die Eindrücktiefe des Stechrohres, kann der Horizont des Sedimentes bestimmt werden, in die der Tracer eingebracht wird. Es können auch mehrere Horizonte gleichzeitig inkubiert werden, wenn jede Spritze eine unterschiedlich lange Nadel erhält. Der In-situ Inkubator ist für Wassertiefen bis 6000 Meter ausgelegt.According to the invention, the problem is solved by a device which uses a sediment core by means of a lancing tube ( 40 ) isolated from the environment and thus simultaneously prepared for the return to the surface. On the upper end of the lancing tube is a two-part injection unit ( 20 and 30 ), which injects the tracer into the sediment. The lancing tube and injection unit are firmly connected to each other and are only separated at the surface to analyze the soil sample. The injection unit consists of a pressure-resistant electronic and motor unit ( 20 ) and a syringe unit flushed by ambient water ( 30 ). About a spindle is emptied by the engine a number of syringes and thus introduced the tracer in the sediment layer. The length of the syringe needle and the indentation depth of the piercing tube, the horizon of the sediment can be determined, in which the tracer is introduced. It is also possible to incubate several horizons at the same time if each syringe receives a needle of different lengths. The in situ incubator is designed for water depths up to 6000 meters.

Das gesamte System ist nur geringfügig größer als die benötigte Bodenprobe selbst und damit klein genug, um von einem ROV (Remotely Operated Vehicle) oder Tauchboot zielgenau eingesetzt zu werden. Hierzu ist der in-situ Inkubator mit einem individuell angepassten Griff (10) ausgestattet.The entire system is only slightly larger than the required soil sample itself and thus small enough to be accurately deployed by a Remotely Operated Vehicle (ROV) or submersible. For this, the in-situ incubator with a customized handle ( 10 ) fitted.

Eine Mikrokontroller-Steuerung sorgt für die exakte Einhaltung der Motorumdrehungen um ein vorher programmiertes Volumen zu injizieren. Die Auslösung erfolgt automatisch bei Erreichen der richtigen Eindrücktiefe des Stechrohres oder durch Ansprechen eines Reed-Schalters von außen mittels Magnet.A Microcontroller control ensures the exact compliance of the Engine revolutions to inject a pre-programmed volume. The trigger takes place automatically when the correct indentation depth is reached of the piercing tube or by addressing a reed switch from the outside by means of magnet.
