DESCRIPTION OF THE INVENTION having as title: "transformer of wave motion and / or flows, in rotation energy, with transducer effect",

Technical field: energy recovery from the composite wave motion of waves (molecular rebounds characterized by imi circles and direction of propagation), currents (continuous displacements of large masses of water), reluctance (alternating flows, determined by long waves reaching low backdrops).

The transformer converts the potential energy of the waves (imi circles and direction of propagation) and / or the kinetic energy of the flows (tides and restia) into mechanical rotational energy.

State of the art: at sea, energy is shown with flows (tides, currents and restia), hydraulic height differences, speeds, overlapping of wave forms; the energy recovery systems are dedicated to the distinct components: waves or motions.

The energy of the wave excursion is detected by means of floats and fluid-dynamic pistons, semi-floating tubes with hydraulic joints, air chambers compressed by wave motion, electromagnet floats with immersed panels or with stator anchored or fixed to the bottom. Energy is also detected from stable currents with traditional penstocks and mills; at sea, submerged wings that float are used, or there are dams that separate areas at different hydrostatic levels communicated by tunnels in which axial turbines (propellers, Kaplan turbines) or axial / radial turbines (Francis turbines) are inserted that preserve the direction of rotation whatever the direction of origin of the flow.

Technical problem: the energy of the sea propagates with composite motions; normally the site of use recommends suitable solutions for the prevalence of waves or currents, neglecting the minority components, but in many sites modest components coexist if distinct, but frequent and appreciable as a whole.

Explanation of the invention: the invention detects the transit of the energy of waves and flows and renders an inconstant force of algebraic sum between the two values. Slow but very powerful impulse, difficult to block, it has an average performance towards any form of transfer in its essence or combination. It must be submerged or semi-submerged, supported by floats or by pilings and / or structures.

The invention comprises the following essential characteristics: a bidirectional duct, specular and rotated with respect to the vertical mean section [X, Y]; of quadrangular cross section [Y, 2], with the upper and lower sides flat (to saturate the molecular rebounds) and longitudinally shaped to direct the flows; the meeting between the sides can be joined and / or beveled; the access volume is divided first with vertical baffles that direct the flows towards the active blades then with horizontal baffles that stop the molecular rebounds and separate the two-level differentials. Inside the duct, there is a wheel called "Impeller" with a vertical axis with radial blades, which rotates in seats located in the middle of the duct. In the impeller, the water enters and flows radially, that is from the perimeter towards the axis and from the latter towards the perimeter; at half height the impeller is sectioned by a circular diaphragm, equipped with a large central hole suitable for allowing the water to enter and flow out on two levels of depth.

Key to drawings: [CS] shaped duct; [Sa] access section;

[Ls] upper side; [Li] bottom side; [Ld] shaped right side; [Ls] left side shaped; [Sv] vertical septum that directs the flows; [So] horizontal septum that separates the rotating motions of the waves; [G] Paddle impeller [P]; [Av] vertical rotation axis; [la] rotation axis engagement; [Df] diaphragm perforated in the center whose peculiarity is to acquire and exploit the energy of the flows and of the vertical components [Cv] relative flow [Fs +] and ebb [Fs-] determined by the molecular rebound of the sea wave.

Proposed solution: activators of the impeller are the flows of currents and the motions of the waves (vector of propagation and circulation of the particles, whose molecules, activated by the passage of crest and hollow, perform a cycle of amplitude proportional to the wave). The vector of the sea flow and the vector of the direction of propagation of the wave are forces that add algebraically and then pass through the duct to give strength to the impeller blades. The effect of the hydrostatic thrust of the crest (inflow) and the depression of the cable (outflow) are added to the aforementioned quantities, which add up in modulus, in fact, while generating flows in the opposite direction, they in any case induce a concordant direction of rotation to the impeller.

Finally, the circles, trapped by the duct, are stopped by it; first they become elliptical (inducing and forcing alternating flows in the duct in contrasting directions placed on two levels, high and low) then, separated from the horizontal septum of the duct and the radial septum of the impeller, they become saturated, establishing a difference in the flow rate of the high and low levels bottom of the duct. Thus separated, the difference in flow rate establishes a difference in potential which, pushed by the direction of propagation of the wave, advances, until it short-circuits in the hole of the diaphragm of the impeller. The hole thus restores the difference in flow between the high and low level of the impeller, the differential flow transfers the kinetic energy to the incoming and outgoing half-blades which push together. In the absence of the diaphragm, the potential (water hammer) determined by the horizontal septum of the duct would short-circuit between the high and low levels of the vanes, however canceling the differential thrust flow. The impeller is powerful, slow and constant with the flows, faster and more impulsive with the waves; it provides faithful spectrograms of wave and current analysis from which the transducer effect and can charge mechanical electrical systems and / or rotate multipolar alternators.

Construction: The prototype is made of folded and welded stainless steel sheets, the blades and partitions have adjustable joints and hinges, in fact the quantity of the blades, inclination and sizing define the performance. The rotation seats are bushings and Teflon; the gaskets guarantee the tightness. The length [X] of the transducer is approximately 2.5 ÷ 3 times the diameter of the impeller; the height [Z] is the dimension of the crest of the type wave; the thickness [Y] depends on the impeller. Impeller: number of blades from 10 to 12 with incidence and curvature for the desired characteristic speed; the diameter [D] is as large as possible to increase the Moment of inertia, height [Z] similar to the duct; diaphragm placed at half height [Z] with depth similar to the blades and hole about one third wide [D]. Vertical deflectors: Height [Z] like the duct, Length [X] from the access to the impeller; Horizontal deflectors: depth [Y] like the duct; length [X] one third [D].

Industrial use: construction of modular pumping units and / or autonomous generators for energy self-consumption. They can be made of polyethylene and steel for 1 ÷ 3kW dynamo; in steel for more powerful units up to 100kW; with ferrocement structure if over 100kW. They can equip breakwater modules and piers; they can be arranged: in stacks, to intercept the most imi motions and / or in series, for long barriers.
