Description

SHELTER FOR CULTURES IN ROWS WITH SOLAR AND WIND GENERATORS

"Photovoltaic-wind shelter suitable for the agriculture".

The invention refers to a shelter with photovoltaic and wind power for agriculture suitable to protect the under plants and to obtaining electricity. In the art photovoltaic systems are known placed onto the ground or onto the faults of roofs. The disposition of these panels onto the ground arranges, however, in the agriculture difficulty to make crops. Often infact, the grounds with photovoltaic panels placed onto the ground remain fallow or arranged for grazing animals. The realization with panels onto faults of roofs in agriculture provides housing mainly on faults of roofs of greenhouses. The crops inside the greenhouses are, however, limited to vegetables, fruit trees of small size or potted plants, being difficult to realize the crops of fruit trees or vines inside the greenhouses. In the art are known the documents US2011/113705, US2009/ 186745, FR2951881 and WO2009/0467595 in which coverings are described with solar panels and wind turbines. These known applications do not provide, however, the exploitation of the air currents that are generated in the under part of the tilted solar panels and to have an active coverage against hail. Object of the invention is a new and original shelter placed onto poles to support rows with supports of the photovoltaic panels arranged with wind turbines between the photovoltaic panels and placed at a height from the ground suitable to permit the crop of the under plants, in particular fruit trees and/or vines planted in rows. The invention is able to use the produced electric energy, other than for a economic return given to the sell of electric energy fed into the network, to feed lamps with timers suitable to help the grow of the plants and of the fruits. Other aim obtained with the invention is given to the fact to be suitable to protect the plants from the hailstorm such as, other to the protection given to the same photovoltaic panel with wind turbine, is able to protect the fruit trees and/or vines with anti-hail nets, the output or the return of which is started to a rain-sensor fitted onto an opening/closing automatic device to be fed by the same electric energy produced to the photovoltaic panels with wind turbines. Other aim given to the invention consists in the fact to have a sandwich structure of photovoltaic panels with interposed wind turbines between the panels and with the upper panel wavy to increase the surface of exposure to the sun. The invented shelter can have different widths, on the base of the row dimensions onto which is placed and of the dimensions of the under plants, to have visually lowest environmental impact. Aim of the invention is, so, to give a covering actuated with support poles for rows with a suitable height to permit the crop onto the under ground, with partial covering of the plants and of the fruits from the rays of sun to help the grow with natural and artificial radiation, being equipped with a programmable lamp, to protect the plant from the hail by a net device with starting of the covering given by a sensor that provides to start the return of the anti-hail nets in absence of perturbations and to have electric energy by the combo action of the photovoltaic panels and the wind turbines present between the panels. This and other advantages and aim of the invention are more apparent to the following description of a preferred but not exclusive embodiment to be consider with the enclosed drawings of sheets 1, 2, 3 and 4 that show in indicative and not limiting way the invention. In particular in sheet 1 the figure 1 is perspective view of the invention. In sheet 2 the figure 2 is perspective view of the invention provided with more wind turbines. In sheet 3 figures 3, 4 and 5 are perspective views of the invention with different kind of joints between the containment bodies. Finally at the sheet 4 the figure 6 is perspective view of an application of the invented shelter onto a row of fruit trees, with the protection nets for the hail closed. The photovoltaic-wind shelter suitable for agriculture consists of a silicon photovoltaic panel 1, for example amorphous mono/polycrystalline silicon or similar, with wavy surface 2 upper closed by a protection glass 3 resisting to the hail and laterally from a containment body 4 with joint 5 between the various panel containment bodies long the parallel lateral surfaces 6. By vertical connection means 7, placed under the containment body 4 of the first photovoltaic panel 1, a second silicon panel 8 is fixed, for example monocrystalline silicon, with sandwich structure and inside space 9 such to permit the housing of wind turbines 10. Said wind turbines are connected to a shaft 1 1, placed through the panel 8 and connected to a generator 12 for the production of electric energy. The wind turbine can be single or consisting of a lot of wind turbines, i.e. more wind turbines with as many generators, with the wind turbines always placed between the photovoltaic panels 1 and 8. Said panels, in different embodiment, can be realised both in amorphous mono/polycrystalline silicon or similar. Onto the panel 1 is present a rain-sensor 13 connected to supply and to a motor 14 to drive mobile arms 15 to put in extension the anti-hail net 16. For long period in which the sensor do not detect the presence of rain, the same sensor 13 gives an impulse to the motor 14 to back the anti-hail net 16. In the upper part 17 of the second panel 8 is, further, present an ultraviolet lamp 18 connected to the mains and with timer 19. Said lamp is fed from the electric grid and to the current production devices, i.e. the panels 1 and 8 and/or to the wind turbines 10. The photovoltaic-wind shelter for the agriculture is supported from poles for rows 20, with wires 21 for the support of the branches of the fruit trees of vines. Said plants are so placed under the invented shelter and cultivated in row, with branches in support or fixed to the wires 21 and pruned across to the direction toward the row must be obtained. The photovoltaic-wind shelter has suitable supports 22 for the photovoltaic panels with wind turbines, on the base of the known art, with L- shaped sections onto which are placed the photovoltaic panels 1 and 8 with wind modules by the joints 5 of the containment bodies 4. In mounting phase the photovoltaic-wind shelter for the agriculture provides the fixing of poles for rows 20 onto the ground. Then are positioned the wires 21 to arranged the cultivation of the rows consisting of fruit trees of vines. Upper to the poles for rows 20 are fixed the supports 22 for the photovoltaic panels. So placed onto the supports 22 the contained body 4 of the photovoltaic panels 1 and 8 and the wind modules, with the containment bodies arranged jointed sides 5 to permit the stable positioning, the electric connections are arranged on the base of the known art. .In working the invented shelter provides the production of electric energy from the photovoltaic panels 1 and 8 and to the generators 12 connected by shafts 11 to the wind turbines 10, with part of the electric energy directly use to the components of the invention. Said wind turbines 10 are started to the convective motions of the air which is heated between the photovoltaic panels 1 and 8, ducted in the inside space 9. The air mass present between the panels 1 and 8 rises toward between the panels, helps to the angle of these. The warm in particular way of the upper panel 1 brings the air present between the panels to rise toward in the inside space 9 limited to the same panels. The wind turbines 10 present long this air flow are put in rotation to generate electric energy. Further, the wind present between the photovoltaic panels helps the motion of the wind turbines. The working is obtained in absence of sun. The wind that blows in the fields is canalized between the photovoltaic panels generating energy by the wind turbines 10 also in absence of sunning. In other embodiment the photovoltaic-wind shelter can be placed also with the panels 1 and 8 and the wind modules across the row. The photovoltaic panels 1 and 8 with the wind turbines 10 between the inside space 9 and the joints 5 can be used, further, in all the other applications as for instance on roofs or on the ground or in water. The invention is possible of several variations and changing all parts of the inventive step, with all the details to be replaced with other equivalent.
