Description
Zur Bekämpfung von Schiffsbewuchs ist be-. reits vorgeschlagen worden, an jeder Schiffsseite vom Schiffskörper und untereinander isolierte, paarweise angeordnete Elektroden zum Zersetzen des Seewassers vorzusehen, dessen Zersetzungsprodukte durch die Strömung über die Schiffswand verteilt werden. Hierbei sollen die bei der Zersetzung entstehenden giftigen Stoffe den Anwuchs töten. Ferner ist to es bei Einrichtungen zum Bekämpfen von Schiffsbewuchs, bei denen von im Seewasser befindlichen Anoden elektrische Ströme auf den Schiffskörper übergehen, schon bekannt, die Anoden aus Arsen-Kupfer-Legierungen in Kabelform herzustellen, um die vergiftende Wirkung auf den Bewuchs zu steigern.To combat ship growth is loading. It has already been proposed that on each side of the ship insulated from the hull and from each other, to provide electrodes arranged in pairs for decomposing the seawater, its Decomposition products are distributed by the current over the ship's wall. Here should the toxic substances produced during decomposition kill the growth. Furthermore is to it with facilities for the control of ship growth, with those of in the sea water electrical currents in the anodes are transferred to the hull, already known, Manufacture the anodes from arsenic-copper alloys in cable form to avoid the poisoning To increase the effect on the vegetation.
Nach der Erfindung werden unter Verwendung von Arsen-Kupfer-Kabeln als Elektroden Einrichtungen der erstgenannten Art dahin,-gehend weiter ausgebildet, daß die Elektroden durch ein ander Außenhaut zu befestigeindes durchlochtes Hüllkabel o. dgl. in dem zur Aufrechterhaltung einer wirksamen Giftstoffabscheidung erforderlichen unveränderlichen Ab-/stand zueinander und im Bereich der unmittelbar die Außenhaut umgebenden Grenzschicht gehalten werden. -According to the invention, arsenic-copper cables are used as electrodes Devices of the first-mentioned type are further developed that the electrodes to be fastened by another outer skin perforated sheath cable o. the like. In the maintenance constant distance required for effective toxin separation to each other and in the area of the boundary layer immediately surrounding the outer skin being held. -
Durch, die erfindungsgemäße Maßnahme wird die Wirksamkeit von Anlagen der vorliegenden
Art verbessert, da die giftigen Zersetzungsprodukte zur dauernden und in ihrer
Stärke unveränderlichen Einwirkung auf den Schiffsbewuchs gebracht werden können.
Durch die erfmdungsgeniäße ,Maßnahme werden
erst die Voraussetzungen geschaffen, unter denen eine wirksame Elektrolyse und Verteilung
der Zersetzungsprodukte über den Anwuchs zu erwarten ist. Dadurch wird ein wirtschaftlicher Betrieb ermöglicht.
In Fig. ι ist die erfindungsgemäße GesamtanOrdnung
an einem Schiff gezeigt, während Fig. 2 die Befestigungsmittel für die Elektroden,
The measure according to the invention improves the effectiveness of systems of the present type, since the toxic decomposition products can be brought to a permanent and unchangeable effect on the ship's vegetation. The measure according to the invention creates the prerequisites under which effective electrolysis and distribution of the decomposition products over the growth can be expected. This enables economical operation.
In Fig. Ι the overall arrangement according to the invention is shown on a ship, while Fig. 2 shows the fastening means for the electrodes,
Fig. 2a eine ellipsenförmige Arsen-Kupfer-Elektrode mit innenliegendem Stromzuführungskabel und2a shows an elliptical arsenic-copper electrode with an internal power supply cable and
Fig. 3 ein Doppelkabel darstellt.Figure 3 illustrates a twin cable.
In einem wellenförmig oder ähnlich ausgebildeten, an der Schiffswand in Schrägrichtung befestigten und gelochten Stahlblech aus rostfreiem Stahl oder Alummiumbronze werden Arsen-Kupfer-Barren von elliptischem Querschnitt isoliert angeordnet, die jeweils durch ein Stromzuführungskabel ,unter sich verbunden sind, das z.B. in die Barren eingegossen ist. Es werden auf diese Weise langgestreckte Kammern gebildet, von deren eingeschlossenen positiven und negativen Elektroden aus die Zersetzung des umgebenden Wassers erfolgt. Diese Anordnung kann bei sehr langen Schiffen außer ,am Bug auch mittschiffs getroffen oder ,beliebig oft wiederholt werden. Durch die flache Gestaltung der Kammern wird eine Verminderung des Schiffswiderstandes nach Möglichkeit vermieden, In a wave-shaped or similar, on the ship's wall in an oblique direction fastened and perforated sheet steel made of stainless steel or aluminum bronze Arsenic-copper ingots of elliptical cross-section arranged isolated, each are connected to each other by a power supply cable that is, for example, cast into the bars is. There are elongated chambers formed in this way, of their enclosed positive and negative electrodes from the decomposition of the surrounding Water takes place. This arrangement can be used at very long ships besides struck amidships at the bow or repeated any number of times will. Due to the flat design of the chambers, a reduction in the ship's resistance is avoided as far as possible.
