DESCRIZIONE dell’invenzione avente per titolo: TESTA PER GENERATORE DI NEVE A NUCLEAZIONE VARIABILE DESCRIPTION of the invention entitled: HEAD FOR VARIABLE NUCLEATION SNOW GENERATOR

DESCRIZIONE DESCRIPTION

Forma oggetto del presente trovato un generatore di neve per le piste da sci. The present invention relates to a snow generator for ski slopes.

L'innevamento delle piste negli ultimi anni ha avuto nell’economia delle società di impianti a fune e comunità montane un ruolo sempre più importante se non indispensabile per garantire la neve sulle piste. Attualmente i sistemi usati per l'innevamento di piste da sci si possono dividere tra generatori "bassa pressione" e "alta pressione". Ambedue i sistemi usano acqua, aria ed energia elettrica per la formazione di neve. The snowmaking of the slopes in recent years has played an increasingly important if not indispensable role in the economy of cableway companies and mountain communities in guaranteeing snow on the slopes. Currently the systems used for the snowmaking of ski slopes can be divided between "low pressure" and "high pressure" generators. Both systems use water, air and electricity to form snow.

Attualmente i generatori di neve possono essere: Snow guns can currently be:

A) generatore a bassa pressione o ventola: è buono per i consumi ma costoso e troppo ingombrante. A) low pressure generator or fan: it is good for consumption but expensive and too bulky.

B) generatore ad alta pressione: è valido per la semplicità costruttiva ma troppo dispendioso di energia. B) high pressure generator: it is valid for the simplicity of construction but too wasteful of energy.

Scopo principale del presente trovato è pertanto quello di realizzare un generatore misto ad asta senza ventola che consenta una produzione di neve con poca energia, e un buon rendimento alle temperature marginali. Questi ed altri scopi vengono realizzati con il trovato in oggetto, le cui caratteristiche principali sono illustrate nelle rivendicazioni che seguono. Ulteriori caratteristiche e vantaggi appariranno maggiormente evidenti nella descrizione dettagliata che segue, di una forma preferita di realizzazione, illustrata a puro titolo indicativo ma non limitativo nell'unito disegno, in cui: The main object of the present invention is therefore to provide a mixed shaft generator without a fan which allows snow production with little energy and good efficiency at marginal temperatures. These and other objects are achieved with the invention, the main characteristics of which are illustrated in the following claims. Further characteristics and advantages will appear more evident in the following detailed description of a preferred embodiment, illustrated purely by way of example but not of limitation in the accompanying drawing, in which:

la figura 1 rappresenta una vista prospettica del manufatto, oggetto del presente trovato; Figure 1 represents a perspective view of the manufactured article, object of the present invention;

la figura 2 rappresenta una vista frontale del nucleatore supplementare; Figure 2 is a front view of the supplementary nucleator;

la figura 3 rappresenta una vista frontale del nucleatore fisso; figure 3 represents a front view of the fixed nucleator;

Con riferimento all’allegato disegno, è stato indicato^ con 1 il manufatto completo del presente trovato. Il manufatto è sostanzialmente costituito da: - un corpo primario 2; uno o più corpi valvola 3; uno o più corpi secondari 4; un corpo finale 5; ugelli per acqua 6; nucleatori aria-acqua 7; nucleatore supplementare 8; valvola azionamento nucleatore supplementare 9; valvole azionamento acqua 1 0; entrata acqua 11 ; entrata aria 12; copertura in materiale plastico 13; direzione del getto acqua nebulizzata dagli ugelli 14; direzioni del getto nucleatori 15. With reference to the attached drawing, 1 indicates the complete product of the present invention. The manufactured article is substantially constituted by: - a primary body 2; one or more valve bodies 3; one or more secondary bodies 4; a final body 5; 6 water nozzles; air-water nucleators 7; additional nucleator 8; additional nucleator actuation valve 9; water actuation valves 1 0; water inlet 11; air inlet 12; plastic cover 13; direction of the atomized water jet from the nozzles 14; jet directions nucleators 15.

Con riferimento alle figure 1 e 2 il corpo primario 2 alimenta di acqua gli ugelli 6 e i nucleatori con aria e acqua 7. La particolare forma del foro di uscita del nucleatore, ellittica o stella, crea un ventaglio molto ampio che cattura più facilmente le goccioline d’acqua che escono dagli ugelli, e nel loro movimento, vengono nucleate in successione da più nucleatori. Nel caso di abbassamento della temperatura vengono azionate le valvole 10 e automaticamente vengono alimentati gli ugelli dei corpi secondari 4. Alle temperature marginali viene azionata la valvola 9 che attiva i nucleatori supplementari 8 With reference to figures 1 and 2, the primary body 2 supplies water to the nozzles 6 and the nucleators with air and water 7. The particular shape of the exit hole of the nucleator, elliptical or star, creates a very wide fan that captures the droplets more easily of water that come out of the nozzles, and in their movement, are nucleated in succession by several nucleators. If the temperature drops, the valves 10 are activated and the nozzles of the secondary bodies 4 are automatically supplied. At the marginal temperatures, the valve 9 is activated, which activates the additional nucleators 8

garantendo un’ulteriore nucleazione all’acqua degli ugelli. Questa ulteriore nucleazione, di maggior potenza rispetto ai nucleatori in cascata 7, comporta una resa alle temperature prossime allo zero, nettamente superiore. Il maggior consumo di aria viene regolato dalla valvola 9 in maniera tale che a temperature definite venga chiusa la mandata, con un notevole risparmio di energia. ensuring a further nucleation to the water of the nozzles. This further nucleation, of greater power with respect to the nucleators in cascade 7, results in a much higher yield at temperatures close to zero. The greater air consumption is regulated by the valve 9 in such a way that the delivery is closed at defined temperatures, with a considerable saving of energy.

Dopo quanto descritto in senso prevalentemente strutturale, il funzionamento del trovato risulta il seguente. Come già accennato, il presente trovato risulta impiegabile nei generatori di innevamento del tipo ad asta ed anche, adattandolo, nel tipo a ventola. Il funzionamento del presente trovato differisce da altri generatori di neve per il sistema di azionamento degli ugelli in cascata, dei nucleatori fissi a foro ellittico sempre in cascata ed i nucleatori supplementari azionati solo quando serve. Infatti, la principale richiesta di aria per nucleare meglio viene fatta alle temperature marginali, vicino allo zero. Avendo la possibilità in automatico di avere nucleatori supplementari solo quando servono, rende il sistema tutto più versatile con la possibilità di consumare di più solo quando effettivamente c’è necessità. La produzione neve aumenta in modo considerevole quando le particelle di ghiaccio, dovuta alla combinazione di aria-acqua, vengono sparate in grande quantità nel getto dell’acqua che esce dagli ugelli; ad una maggior produzione corrisponde anche ad una neve di qualità superiore in assenza d’acqua libera. After what has been described in a predominantly structural sense, the operation of the invention is as follows. As already mentioned, the present invention can be used in snow-making generators of the rod type and also, by adapting it, in the fan type. The operation of the present invention differs from other snow generators for the actuation system of the nozzles in cascade, of the fixed nucleators with elliptical hole always in cascade and the additional nucleators activated only when needed. In fact, the main air demand for nuclear is best done at marginal temperatures, close to zero. Having the automatic possibility of having additional nucleators only when needed, makes the whole system more versatile with the possibility of consuming more only when there is actually a need. Snow production increases considerably when the ice particles, due to the combination of air-water, are shot in large quantities into the jet of water that comes out of the nozzles; higher production also corresponds to higher quality snow in the absence of free water.

Avere più salti di nucleazione e disporre di nucleatori supplementari in caso di necessità rende il nuovo manufatto estremamente valido nel rapporto energetico. Having more nucleation jumps and having additional nucleators in case of need makes the new artifact extremely valid in the energy ratio.

Ovviamente il presente trovato potrà assumere nella sua realizzazione pratica anche forme e configurazioni diverse da quelle sopra illustrate, senza che, per questo, si esca dal presente ambito di protezione. Inoltre tutti i particolari potranno essere sostituiti da elementi tecnicamente equivalenti e le forme, le dimensioni ed i materiali impiegati potranno essere qualsiasi a seconda delle necessità. Obviously, in its practical embodiment, the present invention may also assume forms and configurations different from those illustrated above, without thereby departing from the present scope of protection. Furthermore, all the details can be replaced by technically equivalent elements and the shapes, dimensions and materials used can be any according to the needs.
