Description

SYSTEM FOR PRODUCING ELECTRIC ENERGY
The present invention refers to an optimized system for producing electric energy from sources of renewable energy, in particular wind, water and sun energy.
Photovoltaic tiles are known in the art for capturing sun energy and producing electric energy such as those disclosed, for example, in the following documents:
CN 204271982, which discloses a metallic sun tile composed of a grooved body which allows both fastening the sun cell and passing the wiring box;
CN 202139771, which discloses a photovoltaic tile composed of a photovoltaic cell protected by a transparent cover and inserted in a thermal and fire-preventing thermal insulation.
A system for converting energy is also known in the art, as disclosed in JP 2009091894, based on a plate for capturing sun energy assembled on a tile. The above energy converting system can include a system of hydroelectric turbines, assembled on gutters and waterspouts, equipped with a tank for regulating the flow of rainwater to maximize the kinetic energy. It can further comprise system of wind turbines arranged below the ridge of the roof frame. The system tries to maximize the capture of different renewable energies, though using many components.
A system for capturing and converting sun and wind energy is also known in the art, as disclosed by WO2007007103 , composed of tiles placed on the top of a cover, equipped with photovoltaic panels to exploit sun energy and with wind turbines to exploit wind energy. Every element is equipped with one or more rotors equipped with acoustic deflectors made of foamed plastic material to reduce the transmission of noise. The above system however does not allow maximizing the capture of sun and wind energy, because the whole roof surface is not used, but only its ridge elements.
A system is also known for producing electric energy by exploiting one or more sources of renewable energy, composed of one or more tiles arranged in cascade, the system having use limitation and not guaranteeing a high degree of energetic efficiency, in some climatic situations, such as, for example, rains with debris, the system not being equipped with optimized grids, sun irradiation not being the system perpendicular to the photovoltaic element surface, but the photovoltaic element of the system being fixed on the tile surface, abundant rains and winds being the system equipped with a single turbine insufficient to manage high water and wind flow- rates .
It is clear how the prior art does not provide a system for producing electric energy which is capable of simultaneously guaranteeing a high degree of energetic efficiency and a high capability of adapting itself o various climatic conditions .
Object of the present invention is solving the above prior art problems, by providing an optimized system adapted to produce electric energy from one or more sources of renewable energy, even simultaneously, in a plurality of different climatic conditions.
Another object of the present invention is providing an optimized system equipped with a tile, capable of exploiting high volumes of air and/or water, guaranteeing a high energetic efficiency. A further object of the present invention is providing an optimized system capable of modifying the inclination of the tile depending on the sun position, guaranteeing a high energetic efficiency.
Another object of the present invention is providing a dimensionally optimized system capable of guaranteeing a better management of the flows of air and water and of reducing the occurrence of system clogging phenomena.
The above and other objects and advantages of the invention, as will appear from the following description, are obtained with an optimized system for producing electric energy as claimed in claim 1 or 2. Preferred embodiments and non-trivial variations of the present invention are the subject matter of the dependent claims.

Possibly, the tile 1 can comprise at least one electric unit 20 integrated in the tile 1 itself and adapted to electrically manage the energy produced by the plurality of rotary devices 11 and/or by the plurality of partial flow barriers 50 of the blade type which perform the piezoelectric function, and adapted to manage the handling device 10.
As shown in Figure 6, the first entering means 2a, equipped with the first filtering element 3, is shaped as an overturned "V" profile, reducing the passage of a plurality of debris inside the channeling element 12 of the tile 1, thereby deviating, towards the lower ends of the first entering means 2a, an excess amount of water flow, and preventing accumulation and clogging of the first filtering element 3.
It is known that the energetic efficiency of a photovoltaic element is affected by the incidence angle of the sun rays with respect to the surface of a photovoltaic element; consequently, the handling device 10 adapted to perform an upward or downwards movement, and to incline the first photovoltaic element 4 depending on the incidence of the sun rays, allows the surface of the first photovoltaic element 4 to be perpendicularly irradiated by the sun rays, guaranteeing its maximum efficiency during the day, and in those places where the sun irradiation has a short length.
In particular, the handling device 10 is composed of :
two pairs of rigid elements 23, each upper end and each lower end of each rigid element 23 being respectively connected to at least one upper sliding means 17a and to at least one lower sliding means 17b. In particular, the upper sliding means 17a are adapted to slide on at least one track fastened to the lower surface of the housing element 5, while the lower sliding means 17b are adapted to slide on at least one track fastened on the upper surface of the tile 1;

at least one mobile fulcrum element 19 for each pair of rigid elements 23, placed in a crossing point of the two rigid elements 23.
In particular, the sliding of the upper and lower sliding means 17a, 17b on their respective tracks allows the displacement of the first photovoltaic element 4, arranged in parallel to the upper surface of the tile 1, upwards and downwards along a perpendicular axis to the upper surface of the tile 1.

As shown in Figures 4 and 5, the fulcrum element 19 is adapted to axially slide along at least one groove of each rigid element 23 towards each lower end of the rigid element 23 connected to the upper surface of the tile 1, inducing a rotation of the upper and lower ends of the rigid elements 23 through the plurality of spherical joints 18, the rotation inducing an upward movement along the perpendicular axis to the surface of the tile 1, respectively of the upper portion of the first photovoltaic element 4, and of the lower portion of the first photovoltaic element 4.
Figure 2 shows, as a non-limiting example, a second embodiment of the tile 1 of the system 100 according to the present invention, in which, in particular, the channeling element 12 of the tile 1 is adapted to contain therein a rotary device 21 with a vertical rotation axis, arranged perpendicular to the upper surface of the tile 1.

Moreover, the tile 1, subjected to at least one source of renewable wind energy, allows conveying the wind flow inside the channeling element 12 inducing a counter-clockwise rotation of the plurality of rotary devices 11 and/or a mechanical action on the blade elements 50 placed as partial barrier, so that the blade elements 50 so stressed compress the piezoelectric elements 52 to which they are integrally fastened, if the wind flow is conveyed inside the channeling element 12 through the two or more filtering elements 5 and through the second filtering element 8 of the second entering means 2b, or a clockwise rotation of the plurality of rotary devices 11 and/or a "vibration" (mechanical compression) of the blade- type piezoelectric devices 50, if the wind flow is conveyed inside the channeling element 12 through the first filtering element 3 of the first entering means 2a,· moreover, the tile 1 allows the wind flow to go out of the channeling element 12, respectively through the first filtering element 3 of the first entering means 2a, or through two or more filtering elements 15 and through the second filtering element 8 of the second entering means 2b.
The tile 1 can be subjected simultaneously to the renewable sources of water and wind energy, and allows simultaneously conveying and exiting the water flow and the wind flow, inducing the clockwise rotation or the counter-clockwise rotation of the plurality of rotary devices 11 and/or a "vibration" (mechanical compression) of the blade-type piezoelectric devices 50, respectively depending on a predominance of the water flow with respect to the wind flow or vice versa .
Finally, the tile 1 subjected to at least one renewable source of sun energy through sun irradiation, allows activating the first and the second photovoltaic element 4, 13, converting sun energy into electric energy, and activating a growth process of the botanic element.
The system 100, as shown in Figures 1 and 2, comprises two or more coating panels 1, physically connected with a cascade arrangement through a plurality of fastening and/or engaging elements, and electrically connected in series through a plurality of electric contacts pre-installed in each tile 1, enabling a coating of an upper surface of any extension of a building, such as, for example, a building for living, or an industrial or commercial building, or a warehouse, or a shed, or other similar construction.
Two or more mutually connected coating panels 1 are adapted to optimize the source of water energy due to a gravity fall of meteoric waters through a physical connection between each channeling element 12 of each tile 1, and through a physical connection between the first entering means 2a of a first tile 1 and the second entering means 2b of at least one following tile 1.
