Abstract

Articulated floating platform for marine breeding comprised of cylindrical floats made of polyester, with a peripheral internal crown of polyurethane and ballast chamber, insubmersible (figure 1) and (figures 2 and 3) assembled together by means of planks of type I and type II (figures 5 and 7), hinged by means of stainless steel hinges (figure 8), forming a cross-linked and articulated structure (figure 9) whereon the feeding devices are hanging (ropes, baskets or net-cages) for breeding molluscs and fish in captivity in littoral waters. The adjustment of the flotation line reduces the upper works which, together with its total articulation, minimizes the resistance of the floating platform to the wind, the swell and sea currents. This results in less detachments of molluscs and fish escapes, and increases the duration of the platform.

PLÜDAFORMA FLOTANTE ARTICULADA PARA CULTIVOS MARINOS.-ARTICULATED FLOATING PLÜDAFORM FOR MARINE CROPS.-
Sector de la técnica anterior.- Cultivos industriales marinos en aguas inte¬ riores.Prior art sector.- Marine industrial crops in inland waters.
Estado de la técnica anterior.- En rias y aguas maritimas interiores se vie¬ nen utilizando para el cultivo de moluscos, deter- minadas plataformas eomíinmente denominadas "bate - as" por su forma, constituidas por lineas de flota dores huecos, en metal, poliester u otros materia¬ les, a los que se fija una plataforma rígida, ge¬ neralmente de troncos de madera de eucalipto, que una vez atornillados a los flotadores componen una superficie flotante, totalmente rígida, de la que se suspenden los cebaderos (cuerdas o cestas), en que se crian los moluscos cultivados.State of the prior art.- In estuaries and inland maritime waters, certain platforms commonly referred to as "bats" are used for the cultivation of mollusks, formed by hollow golden fleet lines, in metal, polyester or other materials, to which a rigid platform is fixed, usually made of eucalyptus wood logs, which once screwed to the floats make up a completely rigid floating surface, from which the fathers are suspended (ropes or baskets), in which farmed molluscs are raised.
En la actualidad, gran numero de "bateas" o plataformas se pierden como consecuencia de los — movimientos de la mar, al originarse fácilmente - por rotura la entrada de agua en los flotadores - huecos, o por efecto de la rigidez de la superfi— cié resultante, αue resiste dificilmente las mare- as y oleajes vivos.At present, a large number of "bats" or platforms are lost as a result of the - movements of the sea, when they originate easily - due to breakage of water entering the floats - holes, or due to the stiffness of the surface. As a result, it hardly resists sea waves and waves.
Por otra parte, dichas plataformas carecen - de todo mecanismo de regulación de su linea de fio tación respecto a la superficie de agua, elevándo¬ se excesivamente por encima de la superficie al - principio de la crianza, por falta de peso en la - masa de molusco suspendida, o bien sumergiéndose - excesivamente, cuando dicha masa se hace adulta y su peso aumenta.On the other hand, these platforms lack - any mechanism for regulating their water line with respect to the water surface, rising excessively above the surface at the beginning of the rearing, due to lack of weight in the - mass of suspended mollusk, or submerging - excessively, when said mass becomes adult and its weight increases.
Este hecho hace mas vulnerables a dichas pía taformas al comienzo de la crianza, por cuanto su excesiva altura sobre el nivel de la superficie de agua, favorece la acción devastadora del oleaje, - y perjudica la estabilidad y practicabiliaάd de - las plataformas al final del proceso productivo, - cuando el peso aumenta por efecto del engorde.This fact makes these pious forms more vulnerable at the beginning of aging, because their excessive height above the level of the water surface, favors the devastating action of the waves, - and damages the stability and practicability of - the platforms at the end of the production process, - when the weight increases due to fattening.
Otros defectos constatados de dichas plata— formas se derivan de la disposición en linea de - los flotadores a los costados de la plataforma, di fiσultando la natural circulación de plancton en - el interior del sistema.Other defects found in these platforms are derived from the on-line arrangement of the floats on the sides of the platform, making the natural plankton circulation within the interior of the system difficult.
Como consecuencia de estos hechos, se pierde un procentaje significativo de plataformas, que — acaban hundiéndose en el fondo marino, se dificul- hfermetica, destinado a ser rellenado de lastre, - permitiendo asi graduar en cada ópoca de crianza, y en proporción al peso de la masa de molusco - adouirido en cada fase de engorde, la linea de flo_ tación de cada flotador, para ajustar la altura de la parte no sumergida y reducir con ello, en caso necesario, su exposición a la acción mecánica del oleaje.As a consequence of these events, a significant percentage of platforms is lost, which - they end up sinking into the seabed, it becomes difficult water, destined to be filled with ballast, - thus allowing to graduate in each breeding season, and in proportion to the weight of the mass of mollusk - adouirido in each phase of fattening, the float line of each float, to adjust the height of the part not submerged and thereby reduce, if necessary, its exposure to the mechanical action of the waves.
El dispositivo resultante de la invención es una plataforma modular, articulada por bisagras, - insumergible y dotada de un mecanismo eficiente y de reducido costo de graduación de la linea de fl£ tación, permitiendo de esta forma suspender de los tablones de unión de los flotadores, los cebaderos (cuerdas o cestas) para la crianza de los moluscos o jaulas-redes para la crianza de peces en cautiyi dad.The device resulting from the invention is a modular platform, articulated by hinges, - unsinkable and equipped with an efficient mechanism and a low cost of graduation of the waterline, thus allowing suspension of the float joint boards. , the baits (ropes or baskets) for the raising of mollusks or cages-nets for the breeding of fish in captivity.
