MÁSTIL METEOROLÓGICO MARINO PARA MEDIDA DE  MARINE METEOROLOGICAL MASTER FOR MEASURING
RECURSO EÓLICO  WIND RESOURCE
D E S C R I P C I Ó N D E S C R I P C I Ó N
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a una mástil meteorológico, concretamente a un mástil destinado a soportar elementos de medida relativos a recurso eólico, "in situ" y otros parámetros ambientales, destinado a realizar dichas mediciones a nivel del mar, concretamente en aguas de media y elevada profundidad. The present invention relates to a meteorological mast, specifically to a mast intended to withstand measuring elements related to wind resources, "in situ" and other environmental parameters, intended to perform said measurements at sea level, specifically in average waters and high depth
El objeto de la invención es conseguir un sustancial abaratamiento de costos, tanto en el mástil propiamente dicho como en sus accesorios, así como una mayor facilidad de transporte y montaje. The object of the invention is to achieve a substantial cost reduction, both in the mast itself and in its accessories, as well as greater ease of transport and assembly.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Como es sabido, el paso previo a la instalación de un parque eólico es la caracterización del recurso eólico presente en el emplazamiento. Para la caracterización del recurso eólico es necesario el empleo de mástiles de medida de viento que recojan, mediante diferentes aparatos situados a diferentes alturas, los parámetros necesarios para estimar la energía que generarían los aerogeneradores que se instalasen en ese emplazamiento. As is known, the previous step to the installation of a wind farm is the characterization of the wind resource present at the site. For the characterization of the wind resource it is necessary to use wind measurement masts that collect, by different devices located at different heights, the necessary parameters to estimate the energy that would be generated by the wind turbines that were installed at that site.
Por otro lado existen parques eólicos instalados en la mayor parte de las zonas terrestres con buenos recursos eólicos, lo que ha traído como consecuencia el poner la vista en el mar, a pesar de que en él los costos de instalación y mantenimiento son mayores a los de tierra. En este sentido cabe señalar la Patente de Invención con número de publicación ES 2 324 276 por una plataforma flotante para instalación de energía eólica, de la que es titular la propia entidad solicitante. On the other hand there are wind farms installed in most of the terrestrial areas with good wind resources, which has resulted in putting the view in the sea, although in it the installation and maintenance costs are higher than those of land. In this regard, it is worth noting the Invention Patent with publication number ES 2 324 276 for a floating platform for wind power installation, which the applicant entity itself owns.
El citado problema inherente a las instalaciones marítimas, el mayor coste tanto de su instalación como de mantenimiento, hace que en este caso la caracterización del recurso eólico sea aún mas importante, si esto cabe. The aforementioned problem inherent to maritime installations, the higher cost of both its installation and maintenance, makes in this case the characterization of the wind resource even more important, if this fits.
En la actualidad y para esta caracterización del recurso eólico se utilizan mástiles con capacidad de medición a alturas de decenas de metros, mástiles que se montan sobre plataformas cimentadas al fondo marino, lo que limita su campo de aplicación a profundidades menores de 30 metros. Estos mástiles son del tipo monopilote, lo que requiere una gran cantidad de recursos para su instalación (equipos de hinca flotantes, estudios exhaustivos del lecho marino, etc.). Sin embargo la utilización de mástiles flotantes la instalación es independiente de la profundidad y el tipo de fondo marino. Además no se requieren los equipos altamente especializados necesarios en los mástiles actuales. At present, and for this characterization of the wind resource, masts are used with measuring capacity at heights of tens of meters, masts that are mounted on platforms anchored to the seabed, which limits their scope to depths less than 30 meters. These masts are of the monopilote type, which requires a lot of resources for their installation (floating driving equipment, exhaustive studies of the seabed, etc.). However, the use of floating masts the installation is independent of the depth and type of seabed. In addition, the highly specialized equipment required in current masts is not required.
En este sentido cabe señalar la Patente de Invención ES 32 301 443, en la que sobre el mástil flotante se montan sistemas de medición basados en el sistema LIDAR (Light-Imaging Detection and Ranging), para medición de viento, que necesita la provisión de agua pura para limpiar la lente, agua que es difícil de proporcionar en el mar, de manera que este principio de funcionamiento condiciona las características del tipo de soporte, su funcionamiento y la corrección de los datos del viento obtenidos del movimiento de la propia torre. De forma mas concreta el sistema LIDAR se basa en láser y en el efecto Doppler, y además ese sistemas no permite concretar los movimientos del propio medidor, de manera que los parámetros obtenidos resultan falseados , no ajustándose a la realidad. In this regard, it is worth mentioning the Invention Patent ES 32 301 443, in which measurement systems based on the LIDAR (Light-Imaging Detection and Ranging) system are mounted on the floating mast, for wind measurement, which requires the provision of pure water to clean the lens, water that is difficult to provide at sea, so that this principle of operation conditions the characteristics of the type of support, its operation and the correction of wind data obtained from the movement of the tower itself. More specifically, the LIDAR system is based on laser and the Doppler effect, and that system also does not allow the movements of the meter itself to be specified, so that the parameters obtained are distorted, not adjusting to reality.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
El mástil que la invención propone utiliza como elementos de medida anemómetros convencionales, ultrasónicos y de cazoleta, que permiten una estructuración diferente para el mástil en sí mismo, para el que se ha previsto un carácter modular que lo hace desmontable, lo que facilita su transporte y permite utilizar distintos emplazamientos durante su vida útil. El mástil ofrece una gran versatilidad y permite realizar mediciones a distintas alturas. Ofrece gran estabilidad frente a la escora, frente al giro sobre su propio eje y a la traslación horizontal. El movimiento vertical debido a las variaciones de altura del agua, es pequeño, por ser consistente su línea de flotación, como se verá mas adelante. The mast proposed by the invention uses conventional, ultrasonic and bowl anemometers as measuring elements, which allow a different structure for the mast itself, for which a modular character is provided that makes it removable, which facilitates its transport and allows different sites to be used during their useful life. The mast offers great versatility and allows measurements at different heights. It offers great stability against the heel, against the rotation on its own axis and horizontal translation. The vertical movement due to variations in water height is small, because its waterline is consistent, as will be seen later.
Para ello y de forma mas concreta, el mástil está formado por un fuste y un soporte flotante que, con un sistema de anclaje, queda fijado al fondo marino con pesos muertos, de manera que es capaz de funcionar con escoras menores de 10° en aguas con profundidades medias y altas, estando su rango de profundidades de utilización situado entre los 30 y 200 metros. El fuste es modular, a base de tramos de acero preferiblemente tronco-cónicos, decrecientes en sentido ascendente, unidos mediante bridas atornilladas para facilitar el transporte, como se ha comentado con anterioridad. El soporte está formado por un cilindro central, un tanque flotador y el lastre, presentando el cilindro central uniones desmontables que permiten que actúe como enlace entre las distintas partes del soporte y del fuste. El tanque flotador es coaxial al cilindro central y está formado por compartimentos independientes y estancos unidos al cilindro central, para dar al sistema el empuje necesario que asegure la flotabilidad y la estabilidad requeridas. El lastre está compuesto por bloques de hormigón unidos entre sí mediante sistemas desmontables, todo ello con la finalidad de facilitar su transporte, estando igualmente dicho lastre unido al cilindro central mediante sistemas desmontables. El amarre se realiza mediante tres cadenas poco tensas que unen el tanque flotador con los pesos muertos colocados en el fondo marino, pesos muertos de características similares a los del lastre. For this and in a more concrete way, the mast is formed by a shaft and a floating support that, with an anchoring system, is fixed to the seabed with dead weights, so that it is able to work with heels less than 10 ° in waters with medium and high depths, being its range of depths of use located between 30 and 200 meters. The shaft is modular, based on steel sections, preferably trunk-conical, decreasing in an upward direction, joined by bolted flanges to facilitate transport, as previously mentioned. The support is formed by a central cylinder, a float tank and the ballast, the central cylinder presenting removable joints that allow it to act as a link between the different parts of the support and the shaft. The float tank is coaxial to the central cylinder and is formed by independent and watertight compartments attached to the central cylinder, to give the system the necessary thrust to ensure the buoyancy and stability required. The ballast is composed of concrete blocks joined together by removable systems, all with the purpose of facilitating their transport, said ballast also being connected to the central cylinder by means of removable systems. The mooring is carried out by means of three low tension chains that link the float tank with the dead weights placed on the seabed, dead weights of similar characteristics to those of the ballast.
Según las características del emplazamiento y los requisitos de medida, se pueden utilizar distintos tipos de cilindro central, de flotador y de lastre, como se también se verá mas adelante. Depending on the characteristics of the site and the measurement requirements, different types of central cylinder, float and ballast can be used, as will also be seen below.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
A la vista de las figuras reseñadas, en particular de la figura 1, puede observarse como en el mástil que se preconiza participa un mástil (C), formado por dos módulos tronco-cónicos (1 y 3), unidos entre sí mediante una brida atornillada (2), constituyendo dicho fuste el medio de implantación, a cualquier nivel en altura, de la instrumentación, concretamente los anemómetros ultrasónicos y de cazoleta, la instrumentación ambiental (temperatura, humedad y presión) y los dispositivos GPS, componentes que se sitúan en el exterior del fuste, mientras que la instrumentación de medida y corrección de movimientos (inclinómetros y acelerometros) se sitúan en el interior del mismo. El fuste (F) está unido a un soporte flotante (S) que a su vez está formado por tres partes distintas, un tanque flotador (5), un cilindro central (6) y un lastre (7). La unión entre el fuste (F) y el soporte (S) se hace mediante una brida atornillada (4). El mástil meteorológico flotante dispone además de un sistema de anclaje (A) que mantiene fija la estructura al fondo marino con el concurso de pesos muertos (9). Asociada al sistema de anclaje (A) se instala la instrumentación necesaria para medir olas (dirección y altura), y corrientes (intensidad y dirección). In view of the figures outlined, in particular of Figure 1, it can be seen how a mast (C), formed by two trunk-conical modules (1 and 3), joined together by means of a flange, can be seen in the proposed mast. screwed (2), said shaft forming the means of implantation, at any level in height, of the instrumentation, specifically the ultrasonic and bowl anemometers, the environmental instrumentation (temperature, humidity and pressure) and the GPS devices, components that they are located on the outside of the shaft, while the instrumentation for measuring and correcting movements (inclinometers and accelerometers) are located inside the shaft. The shaft (F) is connected to a floating support (S) which in turn consists of three different parts, a float tank (5), a central cylinder (6) and a ballast (7). The connection between the shaft (F) and the support (S) is made by means of a screwed flange (4). The floating weather mast also has an anchoring system (A) that keeps the structure fixed to the seabed with the deadweight contest (9). Associated with the anchoring system (A), the necessary instrumentation is installed to measure waves (direction and height), and currents (intensity and direction).
Tal como ya se ha apuntado con anterioridad, y tal como muestra la figura 2, el flotador (5) puede adoptar distintas configuraciones, basadas en la existencia de compartimentos (10) unidos entre sí y al cilindro central (6), mediante unión desmontable. As previously noted, and as shown in Figure 2, the float (5) can adopt different configurations, based on the existence of compartments (10) attached to each other and to the central cylinder (6), by detachable joint .
Concretamente la figura 2a muestra un flotador (5) de geometría cilindrica formado por compartimentos en forma de sector circular, así como uno de dichos compartimentos (10) independizado del resto del flotador. La figura 2b muestra un flotador (5) con geometría cúbica y también con compartimentos (10), en una representación similar a la de la figura 2a. Specifically, Figure 2a shows a float (5) of cylindrical geometry formed by compartments in the form of a circular sector, as well as one of said compartments (10) independent of the rest of the float. Figure 2b shows a float (5) with cubic geometry and also with compartments (10), in a representation similar to that of Figure 2a.
En la figura 2c aparece el flotador (5) con geometría cilindrica formado por compartimentos longitudinales. En la figura 2d se muestra un flotador (5) con geometría cilindrica y tronco-cónica, formado también por compartimentos longitudinales. Finalmente en la figura 2e aparece un flotador (5) formado por cilindros longitudinales. Figure 2c shows the float (5) with cylindrical geometry formed by longitudinal compartments. Figure 2d shows a float (5) with cylindrical and conical trunk geometry, also formed by longitudinal compartments. Finally in figure 2e a float (5) formed by longitudinal cylinders.
Cabe señalar que los flotadores mostrados en las citada figura 2 son meros ejemplos de realización práctica que no limitan en absoluto la configuración que pueden adoptar los flotadores (5). It should be noted that the floats shown in the aforementioned figure 2 are mere examples of practical realization that do not limit at all the configuration that the floats can take (5).
Como también se ha dicho con anterioridad y según muestra la figura 3, el lastre (7) también adopta una configuración modular, a base de bloques de hormigón (11) unidos entre sí y al cilindro central (6) mediante una unión desmontable. As it has been said before and as shown in Figure 3, the ballast (7) also adopts a modular configuration, based on concrete blocks (11) joined together and to the central cylinder (6) by a removable joint.
Concretamente la figura 3 muestra un lastre (7) de geometría cuadrada, formado por bloques longitudinales (11), así como uno de estos bloques de forma aislada. Paralelamente la figura 3c muestra un lastre (7) con geometría cilindrica formado por bloques longitudinales (11). Specifically, Figure 3 shows a ballast (7) of square geometry, formed by longitudinal blocks (11), as well as one of these blocks in isolation. In parallel, Figure 3c shows a ballast (7) with cylindrical geometry formed by longitudinal blocks (11).
Similares circunstancias se dan respecto al peso muerto (9) que, como muestra la figura 4, está formado por bloques (13) unidos por sistema desmontable. Similar circumstances occur with respect to the deadweight (9) which, as shown in Figure 4, is formed by blocks (13) joined by a removable system.
Las bases de los muertos (9) son irregulares, con resaltes (12) que este ejemplo de realización práctica adoptan una configuración cuadrada pero que pueden adoptar otras configuraciones y cuya finalidad es mejorar su agarre con respecto al fondo marino. The bases of the dead (9) are irregular, with projections (12) that this example of practical realization adopts a square configuration but that other configurations can adopt and whose purpose is to improve their grip with respect to the seabed.
