Anordnung der Strom rückleitung bei el ektrischen Schleppbooten.
Die Erfindung betritt elektrische Schleppboote, denen elektrischer Strom zugeführt wird und welche sich mittels angetriebener Reibrolle an einem im Wasserlauf verlegten metallischen Schleppzugmittel (Metallband und dgl.) entlangziehen.
Gemäss der Erfindung wird zur Stromrückleitung das metallische Schleppzugmittel verwendet, und zwar entweder ausschliesslich oder zusammen mit einer besonderen Rückleitung, die, wie die Stromzuführung, z. B. als Oberleitung angeordnet sein kann. Ein Teil des Rückleitungsstrornes geht hiebei, da das Schleppzugmittel im Wasserlauf verlegt ist, durch das Wasser und entlastet die metallische Rückleitung. In den meisten Fällen wird der Querschnitt des Schleppzugmittels zur Rückleitung des gesamten Stromes ausreichen, so dass eine zweite Rückleitung entfällt. Wenn neben dem im Wasser verlegten metallischen Schleppzugmittel indessen noch eine besondere Rückleitung vorgesehen wird, kann ihr Querschnitt bedeutend kleiner ausfallen als der der Stromzuführungsleitung, da sie nur einen Bruchteil des Rückleitungsstromes zu übertragen hat.
Man spart mithin in allen Fällen nicht nur an Material für die Rückleitung, sondern man belastet auch die Tragkonstruktion für die Oberleitungen weniger, so dass diese leichter gehalten werden kann. Bei gegebenem Querschnitt kann die Leitfähigkeit des Schleppzugmittels durch Wahl eines geeigneten gutleitenden Materials (z. B. Siliziumbronze) verbessert werden.
Die Zeichnung zeigt eine beispielsweise Ausführungsform. a ist die Stromzuführungsleitung, b der Stromabnehmerbiigel, c der Elektromotor, der über ein Getriebe d die an das Schleppzugmittel f angepressten Reibrollen e antreibt. Von den Reibrollen e ist in der Figur nur die vordere Rolle zu sehen.

Arrangement of the power return on electric tugs.
The invention relates to electric tug boats which are supplied with electricity and which, by means of a driven friction roller, pull themselves along a metallic towing means (metal band and the like) laid in the watercourse.
According to the invention, the metallic towing means is used for power return, either exclusively or together with a special return line which, like the power supply, e.g. B. can be arranged as an overhead line. A part of the return flow goes through the water, since the towing means is laid in the watercourse and relieves the metallic return line. In most cases, the cross-section of the towing means will be sufficient to return the entire current, so that a second return line is not required. If, in addition to the metallic towing means laid in the water, a special return line is provided, its cross-section can be significantly smaller than that of the power supply line, since it only has to transmit a fraction of the return line current.
In all cases, you therefore not only save on material for the return line, but you also load the supporting structure for the overhead lines less so that it can be held more easily. With a given cross-section, the conductivity of the towing means can be improved by choosing a suitable, highly conductive material (e.g. silicon bronze).
The drawing shows an exemplary embodiment. a is the power supply line, b is the pantograph bar, c is the electric motor, which drives the friction rollers e pressed against the towing means f via a gearbox d. Of the friction rollers e, only the front roller can be seen in the figure.
