Abstract

The invention relates to a device which prevents the encrustation of foreign matter on underwater construction parts. Said device comprises a light protecting element (10) and a lift element (2).

Description

Teile von Wasserfahrzeugen, die unter Wasser liegen, sind typischerweise einem Bewuchs ausgesetzt der hauptsächlich aus Algen besteht. Auch andere Lebewesen, wie z.B. Muscheln, besiedeln die unter Wasser liegenden Teile der Wasserfahrzeuge.Parts of submerged vessels are typically exposed to vegetation mainly consisting of algae. Also other living things, like e.g. Shells populate the underwater parts of the vessels.

Eine Folge des Bewuchs ist eine erhöhte Reibung auf Grund der nun nicht mehr glatten Oberfläche. Eine weitere Folge ist, dass auch das Strömungsprofil beeinträchtigt wird. Insbesondere bei stark einseitigem Bewuchs wird das Strömungsprofil ungleichmässig.A consequence of the growth is an increased friction due to the now no longer smooth surface. Another consequence is that also the flow profile is impaired. Especially with strong one-sided growth, the flow profile is uneven.

Des weiteren nimmt das Gewicht eines Bootes durch Bewuchs zu.Furthermore, the weight of a boat increases due to growth.

Dies hat zur Folge, dass mehr Kraft aufgewendet werden muss. Motorfahrzeuge zeigen einen deutlich erhöhten Kraftstoffverbrauch. Andere Wasserfahrzeuge, beispielsweise Gleiter, werden auf Grund des gestörten Strömungsprofils und / oder der erhöhten Reibung nur schwer oder im schlimmsten Fall gar nicht mehr ins Gleiten kommen.As a result, more power must be expended. Motor vehicles show a significantly increased fuel consumption. Other watercraft, such as gliders, are difficult due to the disturbed flow profile and / or increased friction or in the worst case, no longer come into sliding.

Als Gegenmaßnahmen muss der Bewuchs regelmäßig entfernt werden. Hierzu wird entweder der Bewuchs rein mechanisch oder aber unterstützt mit speziellen Reinigungsmitteln entfernt. Hierzu muss das Wasserfahrzeug üblicherweise aus dem Wasser genommen werden, was nicht immer und überall möglich ist, und was auch einen enormen Aufwand darstellt. Des weiteren besteht bei aggressiven Reinigungsmethoden die Gefahr einer Beschädigung der Bootshaut, was eine sogenannte Osmose nach sich ziehen kann..As a countermeasure, the fouling must be removed regularly. For this purpose, either the vegetation purely mechanically or supported with special cleaning agents removed. For this, the watercraft must usually be taken out of the water, which is not always and everywhere possible, and which also represents a huge effort. Furthermore, with aggressive cleaning methods there is a risk of damage to the boat skin, which may entail a so-called osmosis.

Andere Gegenmaßnahmen setzen spezielle Beschichtungen voraus. Beispielsweise können Schiffe mit speziellen Antifouling Beschichtungen geschützt werden. Diese weisen jedoch erhebliche Nachteile, beispielsweise für die Umwelt, auf, da diese häufig Schwermetall, z.B. in organischen Metallverbindungen wie z.B. Tributyl- oder Triphenylzinn und / oder Biozide wie z.B. Triazine, Methylharnstoffe, Dithiocarbonate enthalten.Other countermeasures require special coatings. For example, ships can be protected with special antifouling coatings. However, these have Significant disadvantages, for example, for the environment, as they often heavy metal, eg in organic metal compounds such as tributyl or Triphenylzinn and / or biocides such as triazines, methyl ureas, dithiocarbonates.

Andere Beschichtungen sind so ausgelegt, dass sie sich während der Schutzdauer, zum Teil mit dem Bewuchs, abbauen. Die Folge ist, dass diese Beschichtungen regelmäßig erneuert werden müssen. Hierzu muss das Wasserfahrzeug üblicherweise aus dem Wasser genommen werden, was nicht immer und überall möglich ist, und was auch einen enormen Aufwand darstelltOther coatings are designed to degrade during the protection period, in part with the fouling. The consequence is that these coatings have to be renewed regularly. For this, the watercraft must usually be taken out of the water, which is not always and everywhere possible, and which also represents a huge effort

Darüber hinaus wird das Sediment der Liegeplätze sowohl durch die Beschichtungen als solche aber auch durch die Abbauprodukte so stark belastet, dass dieses häufig als Sondermüll einer Lagerung zugeführt werden muss. Auch führen diese Beschichtungen und deren Abbauprodukte zu Veränderungen in der Tierwelt, beispielsweise zu Zwergwuchs bei Fischen, zur Geschlechtsumandlung einzelner Tiere und sogar zum Verschwinden ganzer Spezies.In addition, the sediment of the berths is so heavily loaded both by the coatings as such but also by the degradation products, that this must often be supplied as special waste storage. These coatings and their degradation products also lead to changes in the animal world, for example to dwarfism in fish, the sex of individual animals and even the disappearance of whole species.

Aus diesen Gründen sind solche Beschichtungen in vielen Ländern verboten.For these reasons, such coatings are banned in many countries.

Um diesen Problemen zu entgehen wurden in der Vergangenheit ortsfeste Vorrichtungen vorgeschlagen, die eine licht- und wasserdichte Verpackung des unter Wasser liegenden Teils vorsehen.To avoid these problems, stationary devices have been proposed in the past which provide a light and waterproof packaging of the submerged part.

Diese Vorrichtungen haben jedoch deutliche Nachteile, da sie eine ortsfeste Anbringung und daher bauliche Maßnahmen erfordern. Nachteilig an diesen Vorrichtungen ist weiterhin, dass diese bei stark schwankenden Wasserständen, z.B. in Fließgewässern, Seitenarmen von Fließgewässern oder Gewässern mit Tiden, nicht eingesetzt werden können, wenn sie nicht an bereits schwimmende Steganlagen angebaut oder integriert sind.However, these devices have significant disadvantages, since they require a fixed attachment and therefore structural measures. A disadvantage of these devices is further that they can not be used in strongly fluctuating water levels, eg in running waters, side arms of streams or waters with tides, if they are not grown or integrated into already floating web systems.

Des weiteren sind sie nicht für einen mobilen Einsatz zum Beispiel für wechselnde Liegeplätze geeignet.Furthermore, they are not suitable for mobile use, for example, for changing berths.

Darüber hinaus erfordern diese Vorrichtungen, dass Wasser, das sich zwischen diesen Einrichtungen und dem zu schützenden Wasserfahrzeug befindet, entfernt wird. Dieses macht anfwändige, für jeden Bootstyp unterschiedliche Konstruktionen notwendig.In addition, these devices require that water located between these devices and the craft to be protected be removed. This makes complicated, for each boat type different constructions necessary.

Eine unbeabsichtigte Einbringung von zersetzungsfähigem Material, zum Beispiel Fischen, kann durch Säurebildung Schäden an der Bootshaut zur Folge haben.Inadvertent introduction of decomposable material, such as fish, may cause damage to the boat skin due to acidification.

Weiterhin erfordert die Anbringung solcher Vorrichtungen an einem zu schützenden Wasserfahrzeug in der Regel zwei oder mehr Personen.Furthermore, the attachment of such devices to a protected watercraft usually requires two or more people.

Eine andere Vorrichtung zur Vermeidung von Bewuchs ist aus WO 01/81167 bekannt.Another device for preventing fouling is known from WO 01/81167.

Es ist daher eine Aufgabe der Erfindung eine Vorrichtung zur Verfügung zu stellen, die einen oder mehrere Nachteile aus dem Stand der Technik vermeidetIt is therefore an object of the invention to provide a device which avoids one or more disadvantages of the prior art

Die Aufgabe wird gelöst durch eine Vorrichtung gemäß Anspruch 1. Vorteilhafte Weiterbildungen sind Gegenstand der abhängigen Ansprüche.The object is achieved by a device according to claim 1. Advantageous developments are the subject of the dependent claims.

Hierbei ist die Grundidee, dass der Bewuchs wegen der Photosynthese lichtabhängig ist. Wird der unter Wasser liegende Teil vor Licht geschützt, so wird ein neuer Bewuchs verhindert. Darüber hinaus kann auch ein bestehender Altbewuchs durch Lichtentzug zum Absterben und Abfallen gebracht werden. Hierzu ist es von Vorteil, wenn die Vorrichtung einen Wasseraustausch ermöglicht und damit Abbauprodukte des Bewuchs ungehindert abfallen können.Here, the basic idea is that the vegetation is dependent on light for photosynthesis. If the submerged part is protected from light, a new growth is prevented. In addition, an existing old growth can be caused by dying light to die and fall. For this purpose, it is advantageous if the device allows a water exchange and thus degradation products of fouling can fall off unhindered.

Die Umsetzung der Grundidee weist eine lichtundurchlässige Fläche auf, die bei Bedarf schwimmend um das Wasserfahrzeug gelegt wird. Hierzu weist die lichtundurchlässige Fläche einen oder mehrere Auftriebselement auf.The implementation of the basic idea has an opaque surface, which is placed floating around the vessel when needed. For this purpose, the opaque surface on one or more buoyancy element.

In Abbildung 1 ist eine Ausführungsform einer erfindungsgemäßen Vorrichtung 1 schematisch dargestellt. Eine erfindungsgemäße Vorrichtung 1 weist ein oder mehrere Lichtschutzelemente, beispielsweise lichtundurchlässige Fläche(n) 10, auf. Im folgenden wird die Erfindung an Hand einer lichtundurchlässigen Fläche näher erläutert.In Figure 1, an embodiment of a device 1 according to the invention is shown schematically. A device 1 according to the invention has one or more light protection elements, for example opaque surface (s) 10. In the following the invention will be explained in more detail with reference to an opaque surface.

Die lichtundurchlässige Fläche 10 kann aus unterschiedlichen Materialien ausgeführt sein, beispielsweise aus folienartigem Material aus bekannten Kunststoffen. Bevorzugt ist sie aus einer weitgehend UV-beständigen Kunststoffolie wie z.B. Teichfolie hergestelltThe opaque surface 10 may be made of different materials, for example of sheet-like material of known plastics. It is preferably made of a substantially UV-resistant plastic film, such as e.g. Pond liner made

An einer Seite der lichtundurchlässigen Fläche 10 kann ein Auftriebselement 2 vorgesehen sein. Das Auftriebselement 2 kann sowohl in die Fläche eingearbeitet sein als auch an der lichtundurchlässigen Fläche 10 befestigt sein.On one side of the opaque surface 10, a buoyancy element 2 is provided be. The buoyancy element 2 may be incorporated into the surface as well as attached to the opaque surface 10.

Das Auftriebselement 2 kann dabei zusätzlich auch bei winterlichen Verhältnissen als Eisschutz dienen. Ebenso kann auch die gesamte Vorrichtung einem verbesserten Eisschutz dienen, da eine verbesserte Zirkulation von 4°C Tiefenwasser zur Verfügung gestellt wird, weswegen ein Einfrieren verzögert oder überhaupt nicht mehr auftritt.The buoyancy element 2 can additionally serve as ice protection even in wintry conditions. Likewise, the entire device may also serve for improved ice protection, since an improved circulation of 4 ° C deep water is provided, which is why freezing is delayed or does not occur at all.

Beispielsweise kann der Auftriebselement 2 als eine mit Gas gefüllte Luftkammer ausgeführt sein.For example, the buoyancy element 2 can be designed as a gas chamber filled with gas.

In anderen, bevorzugten Ausführungsformen kann das Auftriebselement 2 aus schwimmfähigen Naturstoffmaterialien, beispielsweise aus Holz oder Kork, oder aber bevorzugt aus schwimmfähigen Kunststoffen, beispielsweise Neopolen, ausgeführt sein. Diese Ausführungsform hat zudem den Vorteil, dass eine einfache Montage und damit auch Reparatur möglich wird.In other preferred embodiments, the buoyancy element 2 may be made of buoyant natural material materials, for example of wood or cork, or preferably of buoyant plastics, for example Neopolen. This embodiment also has the advantage that a simple assembly and thus repair is possible.

In der besonders bevorzugten Ausführungsform ist das Auftriebselement 2 mehrteilig ausgeführt. Eine Ausführungsform ist in Abbildung 5 dargestellt. Das Auftriebselement 2 besteht aus zwei Teilen 2a, 2b. Die einzelnen Teile 2a, 2b des Auftriebskörpers 2 weisen entsprechende Passungen 22 und Zapfen 21 auf. Die Passungen 22 und Zapfen 21 könnnen selbst arrettierende ausgeführt sein, beispielsweise dadurch, dass die Zapfen konisch und / oder elastisch sind. Die Zapfen 21 dienen zur Aufnahme der Lichtschutzelemente 10 und des Verbindungselements oder der Entfaltungselemente 7 .In the particularly preferred embodiment, the buoyancy element 2 is designed in several parts. One embodiment is shown in Figure 5. The buoyancy element 2 consists of two parts 2a, 2b. The individual parts 2a, 2b of the buoyant body 2 have corresponding fits 22 and pins 21. The fits 22 and pins 21 may be self-locking, for example, in that the pins are conical and / or elastic. The pins 21 serve to receive the light protection elements 10 and the connecting element or the unfolding elements 7.

Die mehrteilige Ausführung der Auftriebselemente 2 unterstützt eine einfache Montage und ermöglicht damit auch eine einfache und schnelle Reparatur.The multi-part design of the buoyancy elements 2 supports easy installation and thus enables easy and quick repair.

Zudem weisen erfindungsgemäße Vorrichtungen mit einem schwimmfähigen Auftriebselement 2 aus Natur- oder Kunsstoffmaterial den weiteren Vorteil auf, dass sie, selbst wenn sie beschädigt sind, nicht mitsamt der Lichtschutzelemente absinken und abtreiben. Anders hingegen Lichtschutzelemente mit Gas gefüllten Luftkammern Werden diese beschädigt, so verlieren die Lichtschutzelemente ihr Auftriebsvermögen nahezu vollständig und die Lichtschutzelemente drohen abzusinken und abzutreiben. Dies würde eine Gefährdung für die Schiffahrt darstellen. Auch Naturschutzbelange würden vernachlässigt werden.In addition, devices according to the invention with a floatable buoyancy element 2 made of natural or synthetic material have the further advantage that they do not sink and abort with the light protection elements even if they are damaged. Otherwise, however, light protection elements with gas-filled air chambers If they are damaged, the light protection elements lose their buoyancy almost completely and the light protection elements threaten to sink and abort. This would pose a threat to shipping. Even nature conservation issues would be neglected.

Einzelne Elemente der lichtundurchlässigen Fläche 10 können entsprechend der Größe des zu schützenden Wasserfahrzeugs zusammengekoppelt werden oder zusammengekoppelt sein. Hierzu sind einzelne Elemente der lichtundurchlässigen Flächen 10 mittels eines Entfaltungselements 7 (in Abbildung 1 nicht dargestellt) miteinander verbunden.Individual elements of the opaque surface 10 may be coupled together or coupled together according to the size of the craft to be protected. For this purpose, individual elements of the opaque surfaces 10 by means of a deployment element 7 (not shown in Figure 1) connected to each other.

Das Entfaltungselement 7 kann zum Beispiel ein Tau oder Gurtband sein, das durch die einzelnen Elemente der lichtundurchlässigen Fläche 10 durchgeführt sein kann.The deployment member 7 may be, for example, a tow or webbing that may be passed through the individual elements of the opaque surface 10.

In einer alternativen Ausführungsform können die einzelnen Elemente der lichtundurchlässigen Fläche 10 nur an den Seiten jeweils mit einzelnen Abschnitten eines Verbindungselementes 7 miteinander verbunden sein. Im folgenden wird, auch wenn nur eine Ausführungsform beschrieben wird, immer von beiden Ausführungsformen ausgegangen.In an alternative embodiment, the individual elements of the opaque surface 10 may be connected to each other only with individual sections of a connecting element 7 on the sides. In the following, although only one embodiment is described, it is always assumed that both embodiments.

Das Entfaltungselement 7 unterstützt das Anlegen der erfindungsgemäßen Vorrichtung 1 an ein Wasserfahrzeug und dient auch der Befestigung der erfindungsgemäßen Vorrichtung 1 am Wasserfahrzeug.The deployment element 7 supports the application of the device 1 according to the invention to a watercraft and also serves to secure the device 1 according to the invention to the watercraft.

Durch diese Anordnung bilden die einzelnen Elemente der lichtundurchlässigen Fläche 10 einen langen, lichtundurchlässigen Vorhang, der um ein zu schützendes Wasserfahrzeug gelegt werden kann. Hierbei ist von Vorteil, dass der Vorhang an den Auftriebskörpern 2 schwimmt.By this arrangement, the individual elements of the opaque surface 10 form a long, opaque curtain surrounding a watercraft to be protected can be placed. It is advantageous that the curtain floats on the buoyancy bodies 2.

Typischerweise wird eine erfindungsgemäße Vorrichtung 1 in der folgenden Weise an ein zu schützendes Wasserfahrzeug angelegt. Zuerst wird ein Ende des Verbindungselementes 7 am Wasserfahrzeug befestigt. Anschließend durch ziehen am anderen Ende des Verbindungselementes 7 die lichtundurchlässige Fläche entfaltet. Dabei kann die lichtundurchlässige Fläche 10 nun beim Ziehen und Entfalten um das zu schützende Wasserfahrzeug gelegt werden. Ist die erfindungsgemäße Vorrichtung 1 vollständig entfaltet so kann auch das andere Ende des Verbindungselementes 7 am Wasserfahrzeug befestigt werden. Dieser Vorgang kann leicht von einer einzigen Person durchgeführt werden.Typically, a device 1 according to the invention is applied to a vessel to be protected in the following manner. First, one end of the connecting element 7 is fastened to the vessel. Then unfolded by pulling at the other end of the connecting element 7, the opaque surface. In this case, the light-impermeable surface 10 can now be placed when pulling and unfolding around the watercraft to be protected. If the device 1 according to the invention is fully deployed, the other end of the connecting element 7 can also be fastened to the watercraft. This process can easily be performed by a single person.

Da die erfindungsgemäße Vorrichtung 1 am zu schützenden Wasserfahrzeug befestigt wird, sind keinerlei bauliche Maßnahmen an den Liegeplätzen erforderlich.Since the device 1 according to the invention is attached to the watercraft to be protected, no structural measures at the berths are required.

Des weiteren kann durch die schwimmende Ausführung die erfindungsgemäße Vorrichtung 1 auch bei stark schwankenden Wasserständen eingesetzt werden. Durch die Anordnung der einzelnen Elementen der lichtundurchlässigen Fläche 10 sind diese für einen mobilen Einsatz, zum Beispiel für wechselnde Liegeplätze, geeignet. Darüber hinaus ist durch die Anordnung der einzelnen Elementen der lichtundurchlässigen Fläche 10 auch der leichte Auf- und Abbau der Vorrichtung durch eine einzige Person möglich. Die erfindungsgemäßen Vorrichtungen sind bei kleineren bis mittleren Bootsgrößen bequem von einer Person zu tragen.Furthermore, the inventive device 1 can be used even in strongly fluctuating water levels by the floating design. The arrangement of the individual elements of the opaque surface 10, these are suitable for mobile use, for example, for changing berths. In addition, by the arrangement of the individual elements of the opaque surface 10 and the easy assembly and disassembly of the device by a single person possible. The devices according to the invention are easily carried by one person in smaller to medium boat sizes.

Da die erfindungsgemäßen Vorrichtungen 1 nicht wasserdicht am Wasserfahrzeug anliegen ist ein Abfallen von bestehendem Altbewuchs gewährleistet, da so ein Wasseraustausch ermöglicht wird und Abbauprodukte des Bewuchs ungehindert abfallen können.Since the devices 1 according to the invention do not rest on the vessel in a watertight manner, falling off of existing old growth is ensured, since this enables a water exchange and degradation products of the vegetation can fall off unhindered.

Abbildung 2 stellt das Verbinden, Vertäuen und Zusammenfalten einer Ausführungsform einer erfindungsgemäßen Vorrichtung 1 durch ein mit Gewichten versehenen Verbindungselement darFigure 2 illustrates the joining, mooring and folding of an embodiment a device 1 according to the invention by a provided with weights connecting element

Um einen einfachen Abbau einer Ausführungsform einer erfindungsgemäßen Vorrichtung 1 zu gewährleisten, befinden sich in den lichtundurchlässigen Flächen 10, Durchführungen 3. Durch diese Durchführungen 3 ist ein weiteres Verbindungselement 4 gleitend geführt. Das Verbindungselement 4 kann zum Beispiel ein Tau oder ein Tampen sein, der durch die einzelnen Elemente der lichtundurchlässigen Fläche 10 durchgeführt ist.In order to ensure a simple dismantling of an embodiment of a device 1 according to the invention, located in the opaque surfaces 10, bushings 3. Through these bushings 3, a further connecting element 4 is slidably guided. The connecting element 4 may be, for example, a rope or a rope carried by the individual elements of the light-impermeable surface 10.

Durch ziehen am Entfaltungselement 7 kann die erfindungsgemäße Vorrichtung 1, wie bereits beschrieben, einfach entfaltet werden. Dies kann selbst von einer Person einfach bewerkstelligt werden. Somit ist ein einfacher Aufbau der Vorrichtung zur Vermeidung von Algenbewuchs möglich.By pulling the unfolding element 7, the device 1 according to the invention, as already described, can be easily deployed. This can easily be accomplished even by one person. Thus, a simple construction of the device to prevent algae growth is possible.

Durch ziehen am Verbindungselement 4 kann eine Ausführungsform einer erfindungsgemäßen Vorrichtung 1 auch einfach wieder zusammengefaltet werden. Dies kann von einer Person bewerkstelligt werden. Somit ist ein einfacher Abbau der Vorrichtung zur Vermeidung von Algenbewuchs möglich.By pulling on the connecting element 4, an embodiment of a device 1 according to the invention can also simply be folded up again. This can be done by one person. Thus, a simple degradation of the device to prevent algae growth is possible.

Bevorzugt ist die Position der Durchführungen 3 zentral in den lichtundurchlässigen Flächen 10 angeordnet.Preferably, the position of the bushings 3 is arranged centrally in the opaque surfaces 10.

Je nach Ausführungsform können auch die Auftriebselemente 2 mit entsprechenden Durchführungen vorgesehen sein.Depending on the embodiment, the buoyancy elements 2 may be provided with corresponding passages.

Abbildung 3 und 4 stellen das mittels Gewichte unterstützte Zusammenfalten von weiteren Ausführungsformen einer erfindungsgemäßen Vorrichtung darFigures 3 and 4 illustrate the weight assisted folding of further embodiments of a device according to the invention

Diese Ausführungsformen weisen zusätzlich zum Entfaltungselement 7, wie zuvor beschrieben, ein Verbindungselement 8 auf. Das Verbindungselement 8 kann zum Beispiel ein Tau oder Tampen sein, wobei das Verbindungselement zwei benachbarte Lichtschutzelemente oder Auftriebselement verbindet und das Verbindungselement an jeweils einem Ende einer lichtundurchlässigen Fläche 10 oder Auftreibselement 2 befestigt ist, wobei die Verbindung zwischen den zwei Enden hergestellt wird, die im entfalteten Zustand am weitesten voneinander entfernt sind.These embodiments have, in addition to the deployment element 7, as described above, a connecting element 8. The connecting element 8 may be, for example, a rope or rope, wherein the connecting element connects two adjacent light protection elements or buoyancy element and the connecting element is attached to one end of an opaque surface 10 or Auftreibselement 2, wherein the connection between the two ends is made in the unfolded state are farthest from each other.

Auf den Verbindungselementen 8 befinden sich Gewichte 9. Die Gewichte 9 können lose oder befestigt sein. Bevorzugt ist die Länge des Verbindungselementes 8 größer als die Länge von zwei Verbunden einer lichtundurchlässigen Flächen 10 oder Auftriebskörpern 2, damit auch eine Dehnung, wie sie beim Umlegen um Biegungen auftritt, weiterhin möglich sind.On the connecting elements 8 are weights 9. The weights 9 may be loose or fixed. Preferably, the length of the connecting element 8 is greater than the length of two composites of an opaque surfaces 10 or buoyancy bodies 2, so that an elongation, as occurs when bending around bends, are still possible.

Durch ziehen an einem Ende des Verbindungselementes 7 kann die erfindungsgemäße Vorrichtung 1, wie bereits beschrieben, einfach entfaltet werden. Hierbei wird beim Aufbau dieser Ausführungsformen das Verbindungselement 8 gestrafft. Beim Aufbau kommt es also zu einer Speicherung von potentieller Energie. Das Verbindungselement 8 steht nun auf Grund der mittels der Gewichte 9 ausgeübten Gewichtskraft unter Zug.By pulling on one end of the connecting element 7, the device 1 according to the invention, as already described, can be easily deployed. Here, in the construction of these embodiments, the connecting element 8 is tightened. When it comes to the construction of a storage of potential energy. The connecting element 8 is now under train due to the force exerted by the weights 9 weight.

Wird nun zum Zusammenfalten einfach ein Ende des Verbindungselementes 7 gelöst, so führt der Zug und die nun frei werdende potentielle Energie dazu, dass die Gewichtskraft zu einem Absinken der Gewichte 9 führt. Das Absinken der Gewichte führt dazu, dass die Enden an denen das Verbindungselement 8 befestigt ist sich näheren. Somit faltet sich die erfindungsgemäße Vorrichtung durch Gewichtskraft zusammen. Somit ist ein einfacher Abbau der Vorrichtung zur Vermeidung von Algenbewuchs möglich, der auch von einer Person alleine einfach zu bewerkstelligen istIf an end of the connecting element 7 is simply released for folding, then the train and the potential energy now released cause the weight force to lead to a drop in the weights 9. The lowering of the weights causes the ends to which the connecting element 8 is attached closer. Thus, the device according to the invention folds together by weight. Thus, a simple degradation of the device to prevent algae growth is possible, which is easy to do even by a person alone

Wie in Abbildung 3 dargestellt können die Verbindungselemente 8 überlappend an beiden Seiten oder wie in Abbildung 4 dargestellt nur auf einer. Seite vorgesehen seinAs shown in Figure 3, fasteners 8 may overlap on either side or as shown in Figure 4 only on one side. Be provided

Durch Wenden oder Drehen der erfindungsgemäßen Vorrichtungen 1 kann ein an der Vorrichtungen 1 auftretender Algenbewuchs auf die gleiche Art und Weise beseitigt werden, da nun die zuvor außen liegenden Seite nun ebenso lichtgeschützt auf der dem Wasserfahrzeug zugewandten Seite angeordnet ist, fällt ein bestehender Bewuchs ab. Insofern ist die Vorrichtung selbstreinigend.By turning or turning the devices 1 according to the invention, algae growth occurring on the devices 1 can be eliminated in the same way, since now the previously outer side is now also protected against light on the side facing the vessel, an existing growth falls away. In this respect, the device is self-cleaning.

Zusätzlich können in allen Ausführungsformen erfindungsgemäßen Vorrichtung 1 die lichtundurchlässigen Flächen am unteren Ende der lichtundurchlässigen Flächen 10 Durchführungen 11 aufweisen, um bei Bedarf relativ zum zu schützenden Wasserfahrzeug gegenüberliegende lichtundurchlässigen Flächen zu verbinden, oder aber um Gewichte 12 anzubringen, falls Wellenschlag oder Strömung es erforderlich machenIn addition, in all embodiments of the present invention, the light-impermeable surfaces at the lower end of the opaque surfaces 10 may have passages 11 to connect opposite opaque surfaces relative to the watercraft to be protected, or to attach weights 12 if wave or flow requires it

Die Gewichte 12 können so bemessen sein, dass das Auftriebselement 2 oder die Auftriebselemente 2 eine senkrechte Stellung relativ zur Wasserfläche einnimmt.The weights 12 may be dimensioned such that the buoyancy element 2 or the buoyancy elements 2 assumes a vertical position relative to the water surface.

Des weiteren kann ein Lichtschutzelement 10 auch aus einem Material hergestellt sein, das Bewuchs abweisen ist, z.B. auf Grund physikalischer oder chemischer Eigenschaften.Furthermore, a light-shielding member 10 may also be made of a material that repels fouling, e.g. due to physical or chemical properties.
