Description

DESCRIZIONE DESCRIPTION

Dell’invenzione industriale dal titolo: TURBINA EOLICA AD ASSE VERTICALE, Of the industrial invention entitled: VERTICAL AXIS WIND TURBINE,

L’invenzione si colloca nel settore della produzione di energia eolica, cioà ̈ ricavata sfruttando la forza del vento, con l’obiettivo di semplificare e ridurre i costi di produzione ma aumentando i rendimenti, ossia la resa. produttiva, rispetto ad altre turbine che vanno solo a sfruttare una forma aerodinamica delle pale. The invention is located in the wind energy production sector, that is, obtained by exploiting the power of the wind, with the aim of simplifying and reducing production costs but increasing yields, ie yield. productive, compared to other turbines that only exploit an aerodynamic shape of the blades.

L’obiettivo viene raggiunto grazie alle caratteristiche dell’invezione, che mira a creare una turbina eolica ad asse verticale, avente la proprietà di incanalare il flusso d'aria prodotto dal vento. The objective is achieved thanks to the characteristics of the invention, which aims to create a wind turbine with a vertical axis, having the property of channeling the flow of air produced by the wind.

L’invenzione à ̈ spiegata nel dettaglio tramite un esempio di realizzazione rappresentato nei disegni. L’esempio mostra: The invention is explained in detail through an example of embodiment represented in the drawings. The example shows:

Nella fig. 2, raffigurante una sezione della turbina eolica ad asse verticale, come l’invenzione à ̈ costituita da una torre di sostegno (7), sulla quale à ̈ fissato un piatto (5), su cui poggia una comune girante (3), collegata, tramite un asse (8) passante attraverso la torre, ad un alternatore. Superiormente alla girante si trova un altro piatto (4). A delimitare la circonferenza perimetrale dei due piatti c’à ̈ una serie di pannelli girevoli (1), che vengono allineati da una guida di allineamento (2) orientata dal vento per mezzo di un timone (6). I pannelli girevoli e i due piatti, posti sopra e sotto la girante, vanno così a formare una camera nella quale viene convogliato il flusso d’aria prodotto dal vento. In fig. 2, depicting a section of the wind turbine with a vertical axis, as the invention consists of a support tower (7), on which a plate (5) is fixed, on which a common impeller (3) rests, connected, through an axis (8) passing through the tower, to an alternator. Above the impeller there is another plate (4). To delimit the perimeter circumference of the two plates there is a series of revolving panels (1), which are aligned by an alignment guide (2) oriented by the wind by means of a rudder (6). The revolving panels and the two plates, placed above and below the impeller, thus form a chamber in which the flow of air produced by the wind is conveyed.

Nella fig. 3 viene illustrata, in prospettiva, la parte principale dell'invenzione, che à ̈ costituita dalla guida di allineamento (2), avente lo scopo di tenere allineati i pannelli girevoli (1) che ruotano intorno ad un asse (1 b), tramite due cuscinetti (1a) posizionati lateralmete all'asse, che vengono vincolati dalla guida in modo da far formare ai pannelli girevoli una parete chiusa. In fig. 3 illustrates, in perspective, the main part of the invention, which is constituted by the alignment guide (2), having the purpose of keeping aligned the rotating panels (1) which rotate around an axis (1 b), by means of two bearings (1a) positioned laterally to the axis, which are constrained by the guide so as to form a closed wall to the revolving panels.

Nella fig. 1, rappresentante l'invenzione vista dall'alto in maniera schematica, si può intuire il suo funzionamento: la guida di allineamento (2) à ̈ una barra avente una curvatura che segue la circonferenza della suddetta camera ed à ̈ interrotta a settori; la guida di allineamento, ruotando intorno alla torre di sostegno (7), viene orientata dal vento in modo da mantenere un settore interrotto nel primo quadrante da 0° a 90° a partire dalla direzione del vento rappresentata dalle frecce. In fig. 1, representing the invention seen from above in a schematic way, its operation can be understood: the alignment guide (2) is a bar having a curvature that follows the circumference of the aforesaid chamber and is interrupted in sectors; the alignment guide, rotating around the support tower (7), is oriented by the wind in order to maintain an interrupted sector in the first quadrant from 0 ° to 90 ° starting from the wind direction represented by the arrows.

Nel settore interrotto, i pannelli girevoli si dispongono liberamente seguendo la direzione del vento, permettendo al flusso d'aria di affluire nella camera delimitata dai due piatti e dagli stessi pannelli girevoli, al cui interno à ̈ alloggiata la girante. In the interrupted sector, the revolving panels are arranged freely following the direction of the wind, allowing the air flow to flow into the chamber delimited by the two plates and by the revolving panels themselves, inside which the impeller is housed.

In questo modo, il flusso d'aria colpisce le pale della girante solo dal lato utile al senso di rotazione e fuoriesce, attraverso i pannelli girevoli lasciati liberi dal successivo settore interrotto della guida di allineamento, nella fattispecie il terzo quadrante da 180° a 270°, in modo da seguire un percorso più lungo e di conseguenza una spinta maggiore. In this way, the air flow hits the impeller blades only from the useful side to the direction of rotation and comes out, through the rotating panels left free by the next interrupted sector of the alignment guide, in this case the third quadrant from 180 ° to 270 °, in order to follow a longer path and consequently a greater thrust.

Le sezioni della guida di allineamento possono essere variabili, cioà ̈ si può regolare la loro lunghezza in modo da adeguare l'apertura per l'entrata del flusso d'aria in base alla forza del vento. The sections of the alignment guide can be variable, ie their length can be adjusted in order to adapt the opening for the entry of the air flow according to the force of the wind.
