Description

Schiffsgeschwindigkeitsmesser Vorliegende Erfindung dient dazu, Schiffsgeschwindigkeitsmesser, die auf Staudruck ansprechen, vor Bewachsungen oder Verschmutzungen zu bewahren oder deren Einfluß zu verhindern sowie von diesen Schäden leicht zu befreien.Ship speedometer The present invention is used to provide ship speedometers, that respond to dynamic pressure, to protect them from vegetation or contamination or to prevent their influence and to free them easily from this damage.

Es sind Schiffsgeschwindigkeitsmesser bekannt, bei denen ein Staudruckmeßgerät entlang einer Führungsschiene an der Außenhaut des Schiffes an die Meßstelle unter der Wasseroberfläche gebracht wird. Erfindungsgemäß ist nun bei solchen Schiffsgeschwindigkeitsmessern zur Vermeidung von Schäden durch Verschmutzung oder Bewachsung die Membran des Staudruckmessers mit einem ihren Rand überragen den Prallkörper versehen und der Träger des Staudruckmessers durch eine in der Führungsschiene durch ein Zahnrad verschiebbare Kette mit scharfkantigen, scherenden Gliedern gebildet. There are known ship speedometers in which a dynamic pressure measuring device along a guide rail on the outer skin of the ship to the measuring point below brought to the surface of the water. According to the invention is now with such ship speedometers to avoid damage caused by dirt or vegetation, the diaphragm of the dynamic pressure meter provided with one of their edge protruding beyond the impact body and the carrier of the dynamic pressure meter by means of a chain with sharp-edged, shearing limbs formed.

Der Schiffsgeschwindigkeitsmesser besteht gemäß Fig. 1 aus einem Staudruckmeßgerät 1. welches an iner Kette 3 befestigt ist, die in einer Führungsschiene 2 läuft, welche an der Außenhaut des Schiffes befestigt ist, wodurch das Staudruckmeßgerät durch das Zahnrad 4 an die Meßstelle unter der Wasseroberfläche gebracht werden kann. According to FIG. 1, the ship's speedometer consists of a Dynamic pressure measuring device 1. which is attached to a chain 3 in a guide rail 2 runs, which is attached to the outer skin of the ship, whereby the dynamic pressure meter be brought by the gear 4 to the measuring point under the water surface can.

Das hierzu verwendete Standruckmeägerät hat gemäß Fig. 2 zur Vermeidung von Schäden durch Bewachsung oder Verschmutzung an der Vorderseite der Membran S einen Prallkörper /, der den Rand der Membran @ überragt. The stand pressure measuring device used for this purpose has to be avoided according to FIG. 2 of damage due to vegetation or contamination on the front of the membrane S a baffle / which protrudes beyond the edge of the membrane @.

Der Staudruckmesser hat in sich einen Raum 12, welcher zur Aufnahme eines Gebers einer Fernmeldeanlage geeignet ist, was jedoch nicht den Gegenstand der Erfindung bildet. The dynamic pressure meter has a space 12 in it, which is used for recording a transmitter of a telecommunications system is suitable, but this is not the subject of the invention.

Die Kette hat Gleitkörper, welche scharfkantig sind, um eine abscherende Wirkung auszuüben, wodurch ein Festklemmen durch Fremdkörper vermieden wird. The chain has sliding bodies, which are sharp-edged, around a shear-off To exert an effect, thereby avoiding jamming by foreign objects.

Die Arbeitsweise ist derart, daß durch Drehung des Zahnrades 4 der an einer Kette , l)efestigte Staudruckmesser 1 mittels tier nil der Außenhaut des Schiffes befestigten Schiene 2 an die Meßstelle unter Wasser gebracht wird, wobei durch die scharfen Kanten der Kettenglieder etwa vorhandene Fremdkörper in der Schiene weggeschert werden. The operation is such that by rotating the gear 4 of the on a chain, l) solidified dynamic pressure meter 1 by means of tier nil the outer skin of the Ship attached rail 2 is brought to the measuring point under water, wherein Any foreign bodies in the rail due to the sharp edges of the chain links be sheared away.

Nun wird der durch die Fahrt hervorgerufene Staudruck von dem Prallkörper 7 aufgenommen und über die geschützte Membran 8 und ein Hebelwerk 10 nach dem Raum 12 gelcitet, wo ein in der Zeichnung nicht gezeichneter Geber einer Fernmeldeanlage den Ausschlag des Staudruckes weiterleitet bis an die gewünschte Stelle im Schiff. Now the dynamic pressure caused by the trip is released from the impact body 7 added and over the protected membrane 8 and a lever mechanism 10 after the room 12 gelcitet, where a transmitter, not shown in the drawing, of a telecommunications system transfers the ram pressure to the desired point in the ship.

Nach erfolgter Messung oder bei fiir den Staudruckmesser drohender Gefahr kann derselbe wieder durch Drehung des Zahnrades 4 emporgezogen werden. After the measurement has taken place or when there is a threat to the dynamic pressure meter Danger can be pulled up again by turning the gear 4.
