Description

Die Erfindung betrifft eine Vorrichtung für strömungsab­ hängige Messungen, die mit einem auf dem Meeresboden ab­ zusetzenden Stativ, einer senkrecht von dem Stativ her­ abhängenden Welle, einem an dem Stativ befestigten, auf die Welle wirkenden Motor und einem an die Welle ange­ setzten Probennehmer versehen ist.The invention relates to a device for downstream pending measurements that depend on the ocean floor with a tripod to be added, one perpendicular to the tripod depending shaft, one attached to the tripod the shaft acting motor and one on the shaft set sampler is provided.

Bei derartigen Bodenwasserprobennehmern ist es von Bedeutung, daß der mit Eintrittsöffnungen versehene Pro­ bennehmer stabil gegen die Strömung ausgerichtet ist. With such soil water samplers it is from Meaning that the Pro provided with inlet openings is stable against the flow.  

Probennehmer mit einem auf dem Meeresboden abzusetzenden Stativ sind aus der US 3 950 999 und der DE 39 30 300 A1 bekannt. Die DE 24 01 008 B2, die DE-AS 10 91 366, die DE-OS 15 98 268, die US 2 368 282 und die US 5 343 768 zeigen Probennehmer, die sich mittels einer Richtungs­ fahne in Abhängigkeit zu der Strömungsrichtung eines Fluids orientieren.Sampler with one to be deposited on the seabed Tripod are from US 3 950 999 and DE 39 30 300 A1 known. DE 24 01 008 B2, DE-AS 10 91 366, the DE-OS 15 98 268, US 2,368,282 and US 5,343,768 show samplers who are using a directional flag depending on the direction of flow of a Orient fluids.

Der Erfindung liegt die Aufgabe zugrunde, einen Boden­ wasserprobennehmer so auszubilden, daß dessen stabile Ausrichtung des Probennehmers gegen die Strömung gewähr­ leistet ist, damit eine störungsfreie Probennahme mög­ lich wird.The invention has for its object a floor Train water samplers so that their stable Ensure the sampler is aligned with the flow is done so that trouble-free sampling is possible becomes.

Erfindungsgemäß wird diese Aufgabe durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst, die Unteransprüche geben vor­ teilhafte Ausgestaltungen an.According to the invention, this object is achieved by a device with the features of claim 1 solved, the sub-claims specify partial configurations.

Die Erfindung wird in der nachfolgenden Beschreibung unter Bezugnahme auf eine Vorrichtung zum Nehmen von Bo­ denwasserproben beschrieben, sie kann aber auch bei­ spielsweise zum Ausrichten von Meßgeräten zur Strömung verwendet werden. Der Begriff "Probennehmer" umfaßt im Sinne der Ansprüche daher auch Meßsonden und dgl. jeglicher Art.The invention is set out in the description below with reference to a device for taking Bo water samples, but it can also be used for for example for aligning measuring devices for flow be used. The term "sampler" includes in Therefore sense probes and the like. of any kind.

In der Figur ist eine Welle 12 erkennbar, die von einem - nicht gezeigten - auf dem Meeresboden abzusetzenden Stativ senkrecht herabhängt. Auf die Welle 12 wirkt ein - ebenfalls nicht gezeigter - Motor, der an dem Stativ befestigt ist. An dem unteren Ende der Welle 12 ist ein Probennehmer 16 angeordnet, der mit - nicht gezeigten - Ein­ trittsöffnungen versehen ist, die durch ein Betreiben des Motors (und damit ein verdrehen der Welle) gegen die Strömung gestellt werden können.In the figure, a shaft 12 can be seen which hangs vertically from a stand (not shown) to be placed on the sea floor. A shaft, also not shown, acts on the shaft 12 and is attached to the stand. At the lower end of the shaft 12 , a sampler 16 is arranged, which is provided with - not shown - a passage openings which can be placed against the flow by operating the motor (and thus rotating the shaft).

Die Welle 12 trägt eine Richtungsfahne 18 in einem um einen Winkel von ± 10° frei zu dieser schwenkbar. Die Richtungsfahne 18 ist mit einem Magneten 22 versehen, der auf ein an die Welle 12 angesetztes, aus Hall- Sensoren bestehendes Sensorfeld 20 wirkt.The shaft 12 carries a direction flag 18 at an angle of ± 10 ° freely pivotable to this. The direction flag 18 is provided with a magnet 22 , which acts on a sensor field 20 which is attached to the shaft 12 and consists of Hall sensors.

Die Richtungsfahne wird sich - innerhalb des zulässigen Winkelbereichs - immer in die Richtung der Strömung stellen und und damit relativ zu dem auf die Welle 12 aufgesetzten Sensorfeld 20 bewegen. Das aus Hall- Sensoren bestehende Sensorfeld 20 erkennt eine Abwei­ chung des Magneten 22 von einer Null-Position (der Mitte des Sensorfeldes 20). Diese Abweichung von der Null­ position wird von dem Sensorfeld 20 an eine - nicht ge­ zeigte - elektronische Schaltung gemeldet, die auf den Motor so wirkt, daß die Welle (und damit das Sensorfeld 20) relativ zu dem Magneten wieder eine Null-Position einnimmt. Der fest auf die Welle 12 angesetzte Proben­ nehmer folgt dieser Bewegung und wird so ständig in die Strömung gestellt.The direction flag will - always within the permissible angular range - move in the direction of the flow and thus move relative to the sensor field 20 placed on the shaft 12 . The sensor field 20 consisting of Hall sensors detects a deviation of the magnet 22 from a zero position (the center of the sensor field 20 ). This deviation from the zero position is reported by the sensor field 20 to a - not shown ge - electronic circuit, which acts on the motor so that the shaft (and thus the sensor field 20 ) assumes a zero position relative to the magnet again. The sampler firmly attached to the shaft 12 follows this movement and is thus constantly placed in the flow.
