DESCRIZIONE DELL'INVENZIONE avente per titolo: "trasformatore di moto ondoso e/o flussi in moto rotativo: condotto saturatore con elica a flusso assiale a pale indipendenti auto orientabili", a DESCRIPTION OF THE INVENTION entitled: "transformer of wave motion and / or flows in rotary motion: saturator conduit with axial flow propeller with independent self-orienting blades",
Campo tecnico: recupero energetico dal moto ondoso composto da onde (rimbalzi molecolari caratterizzati da circoli imi e verso di propagazione) , correnti (spostamenti continui di grandi masse d'acqua), restie (flussi alternati, determinati da onde lunghe giungenti in bassi fondali). Technical field: energy recovery from wave motion composed of waves (molecular bounces characterized by imi circles and direction of propagation), currents (continuous displacements of large masses of water), restia (alternating flows, determined by long waves reaching shallow waters) .
Il trovato, converte l'energia potenziale delle onde (circoli imi e verso di propagazione) e/o l'energia cinetica dei flussi (maree e restie) in energia meccanica di rotazione. The invention converts the potential energy of the waves (imi circles and direction of propagation) and / or the kinetic energy of the flows (tides and rests) into mechanical rotational energy.
Stato della tecnica: in mare l'energia si rivela con flussi (maree, correnti e restie), dislivelli idraulici, velocità, sovrapposizioni di forme d'onda; l'energia si preleva: dall'escursione delle onde con galleggianti abbinati a pistoni fluido-dinamici, oppure con tubi semisommersi dotati di snodi oleodinamici, od anche con volumi in cui l'aria é compressa dal moto ondoso; esistono galleggianti con bobine ed elettromagnete ancorato od infisso al fondo. Si dimostra più conveniente prelevare energia dalle correnti stabili: a terra abbinando condotte forzate e turbine, oppure con i mulini; in mare si impiegano ali immerse che fluttuano, o dighe che separano ambiti a diverso livello idrostatico resi comunicanti da tunnel in cui vi sono inserite eliche a flusso assiale con pale fisse o mobili (Kaplan) o turbine (Francis), le ultime conservano il verso di rotazione qualsiasi sia la direzione di provenienza del flusso. State of the art: in the sea, energy is revealed with flows (tides, currents and restraints), hydraulic height differences, speeds, overlapping waveforms; the energy is collected: from the excursion of the waves with floats combined with fluid-dynamic pistons, or with semi-submerged tubes equipped with hydraulic joints, or even with volumes in which the air is compressed by the wave motion; there are floats with coils and electromagnets anchored or fixed to the bottom. It is more convenient to take energy from stable currents: on the ground by combining penstocks and turbines, or with mills; at sea, immersed wings are used that fluctuate, or dams that separate areas at different hydrostatic levels communicated by tunnels in which axial flow propellers with fixed or mobile blades (Kaplan) or turbines (Francis) are inserted, the latter retain the direction of rotation whatever the direction of origin of the flow.
Le eliche kaplan regolano l'inclinazione della pala con manovellismi tarati per la velocità di afflusso ma, nel particolare, le pale sono tra esse vincolate e invertono il senso di rotazione dell'elica qualora cambi il verso del flusso; anche le eliche di propulsione a passo variabile hanno le pale tra esse The kaplan propellers regulate the inclination of the blade with cranks calibrated for the inflow speed but, in particular, the blades are constrained between them and reverse the direction of rotation of the propeller if the direction of the flow changes; variable pitch propellers also have blades between them
vincolate . bound.
Problema tecnico: premesso che é semplice prelevare energia dai flussi continui, lo é meno quando essa é motore di flussi alternati e difformi, non omogenei; ancor più difficile prelevarla dalle onde marine che non sono flussi bensì trasferimenti di energia tra particelle sollecitate da vento o impatto con altra massa, esse svolgono un rimbalzo con un solo circolo per poi tornare nello stato di quiete. Infatti l'effetto dell'onda si propaga similmente all'onda sonica, perciò per prelevare l'energia di un'onda é necessario prelevare il movimento localizzato sui semicircoli discordi del livello alto e basso del circolo imo, la cui ampiezza significativa dipende dall'altezza della cresta. Technical problem: given that it is easy to take energy from continuous flows, it is less so when it is the driving force of alternating and different, non-homogeneous flows; even more difficult to take it from sea waves which are not flows but transfers of energy between particles stressed by wind or impact with other mass, they rebound with a single circle and then return to the state of rest. In fact, the effect of the wave propagates similarly to the sonic wave, therefore to collect the energy of a wave it is necessary to collect the movement located on the discordant semicircles of the high and low level of the circle imo, whose significant amplitude depends on the ridge height.
Per prelevare i due movimenti opposti (alto e basso) dei semicircoli é necessario captare il circolo con un condotto per poi sezionarlo con un piano orizzontale nei due livelli discordi; infine serve un elica a flusso assiale con pale indipendenti che adattano verso e inclinazione, in tempo reale pur mentre ruota,· infatti se l'elica avesse le pale tra esse vincolate e/o di verso concorde, i flussi discordi a livello alto e basso del condotto la manterrebbero ferma; inoltre é necessario che l'elica ruoti sempre nella stessa direzione qualsiasi sia il verso dei flussi. To collect the two opposite movements (top and bottom) of the semicircles it is necessary to capture the circle with a duct and then dissect it with a horizontal plane in the two discordant levels; finally an axial flow propeller is needed with independent blades that adapt direction and inclination, in real time even while it rotates, in fact if the propeller had the blades constrained between them and / or in concordant direction, the discordant flows at high and low level of the duct would keep it still; moreover it is necessary that the propeller always rotates in the same direction whatever the direction of the flows.
Esposizione dell'invenzione: il trovato é composto da: Description of the invention: the invention is composed of:
• condotto bidirezionale [CC], speculare rispetto la sezione media; intercetta flussi e onde,· • bidirectional duct [CC], mirroring the middle section; intercepts flows and waves,
• setto orizzontale [PO] che stoppa i rimbalzi molecolari e separa i moti differenziali a due livelli; a metà condotto, il piano é interrotto da una sagomatura in cui è posta l'elica; • horizontal septum [PO] that stops molecular rebounds and separates differential motions at two levels; in the middle of the duct, the plane is interrupted by a shaping in which the propeller is placed;
• elica [E] a flusso assiale con asse parallelo [Ae] al condotto; le pale [Pi] dell'elica sono indipendenti l'una dall'altra e possono ruotare ciascuna su un proprio asse [Ap] con angolo alfa limitato; normalmente stanno, per mezzo di sistema di molle antagoniste [Ma], in posizione intermedia stabile [alfa 0] posta tra [alfa -] e [alfa ],- i limiti massimi e - sono definiti da finecorsa [Bfc]; l'asse di rotazione della pala [Ap] non é l'asse di simmetria, perciò quando essa é sollecitata da energia, risponde disponendosi nella posizione per meno incidere il flusso localizzato, ma fornendo sollecitazione sempre concorde all'asse dell'elica e conferendo sempre lo stesso verso di rotazione. • axial flow propeller [E] with axis parallel [Ae] to the duct; the blades [Pi] of the propeller are independent from each other and can each rotate on its own axis [Ap] with limited alpha angle; normally they are, by means of a system of antagonist springs [Ma], in a stable intermediate position [alpha 0] placed between [alpha -] and [alpha], - the maximum limits and - are defined by limit switches [Bfc]; the axis of rotation of the blade [Ap] is not the axis of symmetry, therefore when it is stressed by energy, it responds by placing itself in the position to less affect the localized flow, but providing stress always concordant with the axis of the helix and giving always the same direction of rotation.
• volume a cuneo od ogiva [Og] che racchiude lo spazio occupato dall'asse dell'elica e dai meccanismi; la conformazione accompagna i flussi e li accelera in prossimità delle pale. Qualsiasi sia il transito di energia o vi sia un movimento localizzato sulla pala, essa dinamicamente si dispone in -una qualsiasi posizione posta tra alfa+ e alfa -, il cui vettore risultante di spinta e il vettore di ritorno in posizione stabile (inerzia), fanno ruotare l'asse nello stesso verso; inoltre se anche una sola pala é interessata da forza, le altre in posizione intermedia non agiscono da freno. • wedge or ogive volume [Og] that encloses the space occupied by the propeller shaft and by the mechanisms; the conformation accompanies the flows and accelerates them near the blades. Whatever the transit of energy or there is a localized movement on the blade, it dynamically arranges itself in any position between alpha + and alpha -, whose resultant thrust vector and the return vector in a stable position (inertia), make rotate the axis in the same direction; furthermore, even if only one blade is affected by force, the others in an intermediate position do not act as a brake.
Il trovato va immerso o semisommerso, sostenuto da galleggianti o da palificazioni e/o strutture anche auto-orientabili verso il flusso prevalente, rende un trasformatore ad elica molto dinamico che risponde in tempo reale a qualsiasi variazione e che ruota sempre nella stesso verso, pur velocemente, adatto ad azionare sistemi fluido-dinamici o ad esser accoppiato direttamente a dinamo multipolari, che alimentano condensatori a carica impulsiva, "diodi di non ritorno" ed infine accumulatori a lenta carica . The invention must be submerged or semi-submerged, supported by floats or by pilings and / or structures also self-orienting towards the prevailing flow, making a very dynamic helical transformer that responds in real time to any variation and always rotates in the same direction, even if fast, suitable to operate fluid-dynamic systems or to be coupled directly to multipolar dynamos, which feed capacitors with impulse charge, "non-return diodes" and finally slow-charge accumulators.
Costruzione: il prototipo è in alluminio con sei pale di vetroresina, gli assi in acciaio inox delle pale, ruotano in sedi di teflon; gli assi hanno diametro variabile per definire l'innesto dell'asse nel supporto e sono parzialmente filettati all'estremità interna in cui una sede trattiene una piastrina metallica; quest'ultima limita la massima rotazione della pala (fermandosi su dei perni finecorsa) e permette l'ancoraggio delle molle antagoniste in materiale inox. La tecnica é consigliata fino a eliche di un metro di diametro, oltre si possono impiegare cuscinetti a sfera e giunti premiasse. Il supporto cilindrico delle pale é solidale ad un asse che può avviare direttamente una dinamo o uno snodo cardanico verso la superficie. In posizione stabile, l'inclinazione delle pale incide ortogonale l'asse dell'elica, ma esse possono ruotare sul proprio asse di circa ±40° (il passo massimo, considera la potenza e la velocità massima raggiungibile dall'asse dell'elica); la dimensione del condotto, del setto e delle pale, ed anche la loro quantità, dipendono dall'altezza di cresta dell'onda considerata e dai flussi normalmente presenti nell'ambiente d'impiego. Setto orizzontale: profondità [Y] come il condotto; lunghezza [X] un terzo [D], l'interruzione sagomata contiene l'elica con le pale disposte nella massima angolazione ammessa. Construction: the prototype is in aluminum with six fiberglass blades, the stainless steel blades of the blades rotate in teflon seats; the axes have a variable diameter to define the engagement of the axis in the support and are partially threaded at the internal end in which a seat holds a metal plate; the latter limits the maximum rotation of the blade (stopping on the limit switch pins) and allows the anchoring of the antagonist springs in stainless steel. The technique is recommended up to propellers of one meter in diameter, besides ball bearings and premium joints can be used. The cylindrical support of the blades is integral with an axis that can directly start a dynamo or a cardan joint towards the surface. In a stable position, the inclination of the blades orthogonally affects the axis of the propeller, but they can rotate on their own axis by about ± 40 ° (the maximum pitch considers the power and the maximum speed that can be reached from the propeller shaft) ; the dimension of the duct, of the septum and of the blades, and also their quantity, depend on the crest height of the considered wave and on the flows normally present in the environment of use. Horizontal septum: depth [Y] like the duct; length [X] one third [D], the shaped interruption contains the propeller with the blades arranged at the maximum allowed angle.
Impiego industriale: costruzione di serie per realizzare barriere seriali per formare potenti gruppi generatori e/o gruppi pompanti modulari; oppure per singoli generatori autonomi per autoconsumo energetico idoneo ad alimentare boe, palificazioni e segnalamenti marittimi, stazioni marittime, frangiflutti e pontili. Industrial use: mass production to create serial barriers to form powerful generator units and / or modular pumping units; or for single autonomous generators for self-consumption energy suitable for powering buoys, piling and maritime signaling, maritime stations, breakwaters and piers.
