Description

DESCRIPCIÓN DESCRIPTION
Plataforma flotante floating platform
SECTOR DE LA TÉCNICA TECHNIQUE SECTOR
La presente invención se refiere a una plataforma flotante utilizable en alta mar para disponer equipos, por ejemplo aerog en erado res, en una posición estable y con poca influencia del oleaje. The present invention refers to a floating platform that can be used on the high seas to place equipment, for example, aerogenerators in erators, in a stable position with little influence from the waves.
ESTADO DE LA TÉCNICA STATE OF THE ART
En el estado de la técnica se conocen diferentes plataformas diseñadas para sostener estructuras sobre el fondo marino, lacustre o embalses. Algunas de ellas corresponden a plataformas petrolíferas, de gran tamaño. Otras se refieren a aerogeneradores o estructuras próximas a un puerto. Unos ejemplos se conocen de CN111469992 o CN112128057. In the state of the art different platforms designed to support structures on the seabed, lake or reservoirs are known. Some of them correspond to large oil platforms. Others refer to wind turbines or structures close to a port. Examples are known from CN111469992 or CN112128057.
Estas plataformas han de mantener una cierta estabilidad pese al oleaje o las corrientes. Por ello se ha diseñado sistemas de anclaje al fondo, lastres... que buscan aumentar la estabilidad. Sin embargo, sólo se ha conseguido superar los problemas con el oleaje cuando la plataforma es de gran tamaño. Es necesario poder reducir el efecto de este oleaje también en plataformas de menores dimensiones. These platforms must maintain a certain stability despite the waves or currents. For this reason, anchoring systems have been designed to the bottom, ballasts... that seek to increase stability. However, the problems with waves have only been overcome when the platform is large. It is necessary to be able to reduce the effect of this wave also on smaller platforms.
El solicitante no conoce ninguna plataforma de características similares a la invención. The applicant is not aware of any platform with characteristics similar to the invention.
BREVE EXPLICACIÓN DE LA INVENCIÓN BRIEF EXPLANATION OF THE INVENTION
La invención consiste en una plataforma flotante según las reivindicaciones. Sus diferentes variantes ofrecen mejoras sobre el estado de la técnica. The invention consists of a floating platform according to the claims. Its different variants offer improvements over the state of the art.
La plataforma flotante posee un cajón, generalmente de sección circular, pero que pude tener otras formas. El cajón es flotante y comprende una o más aletas inferiores peñmetrales que se hunden hacia la parte inferior, generalmente verticales. Las aletas pueden estar a corta distancia del perímetro sin afectar a la estabilidad. El cajón puede estar hueco, pero preferiblemente comprende un relleno de material ligero, de densidad inferior a 1g/cm3. Por ejemplo poliestireno expandido cuya densidad es inferior a 0.03g/cm3. The floating platform has a drawer, generally circular in section, but it could have other shapes. The caisson is floating and includes one or more perimeter lower fins that sink towards the bottom, generally vertical. The fins can be a short distance from the perimeter without affecting stability. The box can be hollow, but it preferably comprises a padding of light material, with a density of less than 1g/cm 3 . For example expanded polystyrene whose density is less than 0.03g/cm 3 .
En una realización preferida, la plataforma posee un lastre inferior, normalmente dispuesta en la parte inferior de una columna. In a preferred embodiment, the platform has a lower ballast, normally arranged at the bottom of a column.

DESCRIPCIÓN DE LOS DIBUJOS DESCRIPTION OF THE DRAWINGS
Se presenta una serie de figuras para facilitar la comprensión de la invención: A series of figures is presented to facilitate the understanding of the invention:
Figura 1 : Vista lateral de un ejemplo de realización de la invención. Figure 1: Side view of an embodiment of the invention.
MODOS DE REALIZACIÓN DE LA INVENCIÓN MODES OF CARRYING OUT THE INVENTION
A continuación se pasa a describir de manera breve un modo de realización de la invención, como ejemplo ilustrativo y no limitativo de ésta. An embodiment of the invention is briefly described below, as an illustrative and non-limiting example thereof.
En la figura 1 se aprecia un corte esquemático de un ejemplo de realización. Comprende un cajón (1 ) hueco con un relleno (2) de baja densidad, como poliestireno expandido... El material del relleno (2) debe tener también resistencia química por si parte del agua entra al interior del cajón. Figure 1 shows a schematic section of an embodiment example. It comprises a hollow box (1) with a low-density filling (2), such as expanded polystyrene... The filling material (2) must also have chemical resistance in case part of the water enters the interior of the box.
El cajón (1) puede estar formado por vahas partes unidas entre sí, dejando vahos huecos, o un único hueco. The drawer (1) can be made up of various parts joined together, leaving hollow openings, or a single hole.
En la parte inferior del cajón (1) se dispone una columna (3), generalmente de sección constante, rematada en un lastre (4). El lastre (4) puede ser de posición ajustable en la columna (3) y también puede asistir para aportar estabilidad con la presencia de corrientes. In the lower part of the box (1) there is a column (3), generally with a constant section, topped with a ballast (4). The ballast (4) can be adjustable in position on the column (3) and can also help to provide stability in the presence of currents.
El perímetro del cajón (1), hacia abajo, dispone de unas aletas (5) a modo de falda que siguen aproximadamente el perímetro. Las aletas (5) pueden corresponder a una única aleta (5) que cubre todo el perímetro o vahas aletas (5) con espacios entre ambas. Igualmente, las aletas (5) pueden ser cerradas o poseer oficios pasantes. Las aletas (5) ayudan a reducir el efecto del oleaje en la estabilidad de la plataforma. The perimeter of the drawer (1), downwards, has flaps (5) in the form of a skirt that approximately follow the perimeter. The flaps (5) can correspond to a single flap (5) that covers the entire perimeter or several flaps (5) with spaces between them. Likewise, the flaps (5) can be closed or have through holes. The fins (5) help reduce the effect of waves on the stability of the platform.
La profundidad de las aletas (5) se definirá según las condiciones locales, básicamente el tipo de corrientes y la altura máxima del oleaje (datos históricos, por ejemplo), y por las dimensiones y la carga de la plataforma. Se puede determinar la profundidad óptima en pruebas en tanque, por simulaciones... El espesor se definirá para que la aleta resista adecuadamente y no entre en resonancia. El espesor puede ser constante o no, siendo en ese segundo caso más delgado en la punta de la aleta. The depth of the fins (5) will be defined according to local conditions, basically the type of currents and the maximum height of the waves (historical data, for example), and by the dimensions and load of the platform. The optimal depth can be determined in tank tests, by simulations... The thickness will be defined so that the fin resists adequately and does not enter into resonance. The thickness may or may not be constant, being in this second case thinner at the tip of the fin.
La plataforma, en uso, queda anclada al suelo o a otras estructuras para limitar sus movimientos por viento, corrientes u oleaje. The platform, in use, is anchored to the ground or to other structures to limit its movements due to wind, currents or waves.
