Description

Fahrtmesser für Schiffe mit Meßturbine oder Meßwasserrad. Fahrtmesser für Schiffe, die auf dem Antrieb einer Turbine, eines Wasserrades o..dgl. durch das vom Schiff ,durchschnittene Wasser beruhen, besitzen die Eigentümlichkeit, d'aß ,die Umdrehungsgeschwindigkeit der Turbine, des Wasserrades usw. sich nicht im gleichen Verhältnis wie die Schiffsgeschwindigkeit ändert, also jener nicht proportional ist. Solange die Fahrt des Schiffes lediglich. abgelesen werden soll, kann diesem Umstande einfach durch entsprechende Einteilung der Ableseskala Rechnung .getragen werden. Benutzt man dagegen die Angaben des Fahirtmessers zur Ermittlung und Aufzeichnung des zurückgelegten Schiffsweges, wie dies z. B. in Patentschrift 272401 beschrieben ist, so bewirkt die mangelnde Proportionalität der Umdrehungen .der Meßturbine mit der Schiffs.-geschwindigkeit störende Ungenauigkeiten im Endergebnis.Airspeed indicator for ships with measuring turbine or measuring water wheel. Airspeed indicator for ships that o..d the like on the drive of a turbine, a water wheel. by the waters cut by the ship have the peculiarity of being , the speed of rotation of the turbine, the water wheel, etc. are not the same Ratio as the ship's speed changes, so that not proportionally is. As long as the ship is only moving. should be read, this can Circumstances are simply taken into account by dividing the reading scale accordingly will. If, on the other hand, the information from the maneuver is used for identification and recording the traveled ship route, as z. B. in patent specification 272401 described is, so causes the lack of proportionality of the revolutions .der measuring turbine with the ship's speed disruptive inaccuracies in the end result.

Diesem Übelstand wird nach der Erfindung da=durch abgeholfen, daß das messende Organ je nach der jeweiligen Schiffsgesch'windsgkeit hinsichtlich seiner Betriebsverhältnisse oder seiner Stellung zum Schiff so beeinflußt wi=rd, daß die Proportionalität der Geschwindigkeiten: hergestellt ist.According to the invention, this inconvenience is remedied by the fact that the measuring organ depending on the respective Schiffgesch'windsgkeit its Operating conditions or its position in relation to the ship is so influenced that the Proportionality of the speeds: is established.

Zur Änderung der Betriebsverhältnisse stehen verschiedene Mittel zur Verfügung: Beispielsweise wird mit der Turbine usw. ein von ihr angetriebenes Fliehkraftpendel verbunden, das in den Meßbereichen, in denen die Turbine relativ zu viel Umdrehungen macht, eine kraftverzehrende Wirbelstrom-oder magnetische Bremse in entsprechender Märke eingeschaltet (>der das Getriebe verstellt, das die Turbine mit dLm anzeigenden Organ (Zählwerk, Koppeltisch usw.) verbindet.Various means are available to change the operating conditions Available: For example, a centrifugal pendulum driven by the turbine etc. is created connected, that in the measuring ranges in which the turbine revolves too much makes, a power-consuming eddy current or magnetic brake in corresponding Marks switched on (> which adjusts the gearbox that the turbine indicates with dLm Organ (counter, coupling table, etc.) connects.

Oder aber es wird Gebrauch gemacht von der bekannten Tatsache, daß ein. Log auch bei ein und derselben Schiffsgeschwindigkeit mit verschiedenen Umdrehungszahlen läuft, je nachdem es näher oder weiter von der Bordwand entfernt in dlas. Wasser eingesetzt wird. Man ändert,den Abstand.' des Meßorgans von der Bordwand, oder dem Schiffsboden je nach der Schiffsgeschwindigkeit, und kann auch; so ohne Beeinflussung des Getriebes zwischen Turbine und Fahrtanzeiger wieder die Proportionalität herstellen.Or use is made of the known fact that a. Log also at the same ship speed with different RPMs runs, depending on whether it is closer or further away from the ship's side in dlas. water is used. You change the distance. ' of the measuring element from the ship's side, or the Ship bottom depending on the ship's speed, and can also; so without any influence of the gearbox between the turbine and the trip indicator restore the proportionality.

Zur Änderung des Abstandes genügt es, das Meßrohr innenbords mit einer Einteilung für die verschiedenen Fahrtgeschwindigkeiten des Schiffes zu versehen und' mach den unkorrigierten Angaben des Fahrtmessers das Meßrohr so weit auszuschieben, daß sieh die darauf angebrachte Zahl für die betreffende Fahrt reit einer festen Nullmarke deckt. Oder es kann durch einen Elektromotor, der von dem Fahrtmesser gesteuert wird, oder eine sonst geeignete mechanische Vorrichtung das Meßrohr immer, .der jeweiligen Fahrt entsprechend mehr oder weniger tief in das Wasser einigesenkt werden, wodurch die Proportionalität ständig selbsttätig herbeigeführt. wird.To change the distance, it is sufficient to connect the measuring tube inboard with a To provide classification for the different speeds of the ship and 'make the uncorrected information of the airspeed indicator to extend the measuring tube so far, that see the number on it for the journey in question rides a fixed one Zero mark covers. Or it can be powered by an electric motor powered by the airspeed indicator is controlled, or another suitable mechanical device, the measuring tube is always, .sunk more or less deeply into the water according to the respective journey , whereby the proportionality is constantly brought about automatically. will.
