PIATTAFORMA PIVOTTANTE per il VINCOLO a TERRA PIVOTING PLATFORM for GROUND LINKING

di un AEROGENERATORE VOLANTE of a FLYING AIR GENERATOR

Il presente trovato descrive meglio nei particolari la piattaforma pivottante per il vincolo a terra citata nella domanda di brevetto n. RM 2008 A 000425 del 04.08.08 dal titolo “AEROGENERATORE VOLANTE AD ASSETTO VARIABILE” e, in particolare, illustra il sistema ideato per scaricare sulla terraferma verso l’utilizzo finale tutta la energia prodotta in quota dall’aerogeneratore. The present invention better describes in detail the pivoting platform for the ground constraint mentioned in the patent application no. RM 2008 A 000425 dated 04.08.08 entitled "FLYING WIND GENERATOR WITH VARIABLE TRIM" and, in particular, illustrates the system designed to unload all the energy produced at altitude by the wind generator on the mainland towards the final use.

Un grosso tubo di acciaio (3) viene annegato in una opportuna piattaforma di calcestruzzo (1) che, in genere ma non sempre, dovrà essere provvista di pali di fondazione per contrastare le notevoli sollecitazioni che le funi (10) imprimono alla intera piattaforma. Sul tubo (3) sono installati cuscinetti radiali ed assiali (4) che sorreggono un altro grosso tubo (5) il quale potrà quindi ruotare di un qualsiasi angolo attorno al tubo fisso (3). Al tubo (5) è vincolata una struttura metallica (12) che consiste in una piattaforma ove dovranno essere alloggiati gli argani (9) con opportuni controventi per resistere alle sollecitazioni impresse. Gli argani (9) vincolati alla piattaforma (12) azionano funi metalliche oppure, in alternativa, funi in kevlar con anima in rame, che svolgono il doppio ruolo di tenere vincolato a terra l’aerogeneratore e di condurre fino al terreno la energia elettrica generata a bordo. Detti argani (9) saranno in genere isolati elettricamente con isolatori (11) rispetto alla piattaforma rotante (12) per agevolare le operazioni di manutenzione e da ogni complessivo formato dall’argano (9) (in genere oleodinamico) e dagli isolatori (11) parte un conduttore di connessione (8) che va a raggiungere gli elettrodi (7) che hanno la loro estremità inferiore immersa in vasche circolari (6) riempite con mercurio. Dalle vasche di mercurio (6) partono conduttori fissi annegati nella piattaforma di calcestruzzo (1) o, al limite, poggiati sulla stessa che raggiungono gli isolatori (13) dai quali opportuni cavi trasferiranno la energia elettrica fino alla sottocentrale dove saranno installati gli inverters per il controllo della frequenza e della tensione. A large steel tube (3) is buried in a suitable concrete platform (1) which, generally but not always, must be provided with foundation piles to counteract the considerable stresses that the ropes (10) impart to the entire platform. Radial and axial bearings (4) are installed on the tube (3) which support another large tube (5) which can then rotate at any angle around the fixed tube (3). A metal structure (12) is attached to the tube (5) which consists of a platform where the winches (9) must be housed with suitable bracing to resist the stresses applied. The winches (9) attached to the platform (12) drive wire ropes or, alternatively, kevlar ropes with a copper core, which play the double role of keeping the wind turbine tied to the ground and conducting the generated electricity to the ground. on board. Said winches (9) will generally be electrically insulated with insulators (11) with respect to the rotating platform (12) to facilitate maintenance operations and by each assembly formed by the winch (9) (generally hydraulic) and by the insulators (11) a connection conductor (8) starts which reaches the electrodes (7) which have their lower end immersed in circular tanks (6) filled with mercury. Fixed conductors embedded in the concrete platform (1) or, at the limit, resting on it, reach the insulators (13) from which appropriate cables will transfer the electricity to the substation where the inverters will be installed for frequency and voltage control.

Gli argani (9) raffigurati nei disegni sono in numero di tre poiché si è partiti dalla ipotesi di generazione trifase a bordo dell’aerogeneratore e di utilizzare lo stesso cavo sia per il vincolo dellp’aerogeneratore a terra che per il traefrimento della energia. The winches (9) depicted in the drawings are three in number since we started from the hypothesis of three-phase generation on board the wind turbine and to use the same cable both for the constraint of the wind turbine on the ground and for the extraction of energy.

Nel caso in cui si decidesse di usare per le funzioni vincolar cavi separati da quelli destinati a funzioni di trasferimento elettrico e/o nel caso in cui si generi a bordo energia elettrica continua anziché alternata trifase, gli argani (9) potranno essere in numero diverso dai tre indicati nei disegni senza però nulla togliere alle rivendicazioni del presente trovato. In the event that it is decided to use separate cables for binding functions from those intended for electrical transfer functions and / or in the case in which direct electricity is generated on board instead of three-phase alternating, the winches (9) may be in different numbers from the three indicated in the drawings without however detracting from the claims of the present invention.

In tali casi, in particolare, gli argani destinati al solo tiro meccanico non avranno ovviamente i blocchi isolanti (11) In such cases, in particular, the winches intended for mechanical pulling only will obviously not have the insulating blocks (11)

La fig.1 è una vista generale dell’intero sistema. Fig. 1 is a general view of the entire system.

La fig.2 ingrandisce i particolari del trasferimento della energia elettrica dalle vasche di mercurio (6) agli isolatori (13. Fig. 2 enlarges the details of the transfer of electrical energy from the mercury tanks (6) to the insulators (13.

La fig.3 mostra i particolari degli ancoraggi degli argani (9) e dei conduttori (8) che vanno a collegarsi con gli elettrodi ruotanti (7) Fig. 3 shows the details of the anchorages of the winches (9) and of the conductors (8) that connect with the rotating electrodes (7)

Nella fig.4 si vedono meglio il sistema di rotazione del tubo rotante (5) attorno al tubo fisso (3) e le vasche circolari (6) riempite di mercurio. In fig. 4 you can see better the rotation system of the rotating tube (5) around the fixed tube (3) and the circular tanks (6) filled with mercury.
