Definitions

• the present invention relates to a device for preventing undesired organisms, such as, for instance, fouling of algae, barnacles and mussles, to adhere and increase friction upon driving objects, for example boats, in water.
• undesired organisms such as, for instance, fouling of algae, barnacles and mussles
• Vegetation on the bottom of boats and other floating objects is a big problem, inter alia depending on that the vegetation protective paints that are used nowadays not are efficient enough, since the vegetation after all is growing and brings many
• This belt is provided with a device in order to make it have a good contact and thereby increase the friction against the bottom.
• These previously known devices have proven difficult to function in a satisfactory way and they have not proven efficient enough either. The problems associated with these solutions have now been eliminated thanks to the invention disclosed herein.
• the object of this invention is to achieve a device through which the vegetation on the bottom of a floating object is prevented in an efficient manner.
• the device according to the invention consists of, in contrast to inter alia the above mentioned prior art, a mat that is positionally fixable under the bottom of the boat, having a size and shape adapted to boat in question.
• the mat is manufactured of plastic tubes with closed ends, alternatively rope or homogeneous cord, which has a lifting power in itself due to that the mat has a density lower than water, whereby the mat is pressed upwards to abut closely against the bottom in question so that all vegetation is deprived of its ability to grow onto it since movement and contact between the mat and the bottom in question arise.
• the drawing shows a preferred embodiment of a vegetation preventing device 1 in the form of a mat (2) according to the present invention.
• the mat 2 is intended for different types of floating objects and above all it is intended to be used in harbours or in places where boats or other floating objects are moored and in a way that so the mat 2 completely covers the bottom of the boat, so that the movement of the mat in relation to the bottom of the boat and in combination with contact with the same vegetation is prevented from arising and increasing.
• the mat 2 consists of a resilient, floating material, for example plastic tubes with closed ends or, alternatively, rope or homogenous cord 3.
• the increase of the abutment pressure against the object, which may be a boat, may be achieved through a larger diameter of the cleaning tube 3 or through adjustment of the density of the material.
• the mat 2 in the shown example consists of a grid system 4 of suitable mesh size and which also is adapted to the desired lifting power and contact over mainly the entire surface of the mat 2, which is intended for abutment against the bottom of the boat in question and a ratio A:B in respect of width and length for the cavities 6 exhibited by the mat 2 may be adjusted depending on the size and shape of the object, so as to achieve an efficient pressure upwards and contact of the mat 2 through the resulting water pressure.
• this ratio is 1 :5, but of course it may also be for instance 5:1 or other ratios giving the same result in respect of efficiency.
• a rectangular frame 5 having a diameter around the entire mat 2 that is larger than the working cleaners 3 with inclined grids and forming the same is fastened to these to hold the mat 2 fixed in its position.
• the abrased fouling material Through its small touching surface through the cleaning tubes 3 against the bottom of the boat and the large cavity 6, which exists in the structure, it is allowed for the abrased fouling material to sink to the bottom of the sea instead of, as may be the case with other conventional devices which thereby become very heavy and difficult to handle and therefore these entire devices after some time even sink.
• the device according to the invention never sinks thanks to its small fouling surface in relation to the lifting power of the mat 2.
• Floating objects that use this type of mat need not be painted with base paint, since the mat prevents all vegetation from starting to grow and increase in an efficient manner and the possible vegetation which has managed to attach when the object has been in a different place disappears in a short time when the mat 2 acts against the bottom.
