The present invention concerns a floating unsin able platform, with a system for the utilization of the hydrostatic pressure for the production of electric energy in a submerged generating s t a t i o n . Furthermore , the platform may be exploited as a carrying structure for the foundation base of bridges , floating touristic villages , floating platforms for oil extraction and s imilar constructions , making use of said hydrostatic pressure.

The floating platform according to the present invention comprises a trellis-work of cylindrical vertical columns connected to horizontal rings and is realized with double tubes of synthetical material , and iron cables placed in tension in a sheathing inserted between the circular crown formed by two tubes , so as to obtain a solid structure, resistant to the waves of the sea and also resistant to the marine corrosion.

The problem of the research of renewable energy is very urgent and is actually directly proportional to the industrialization;

The essays to increase the sources of electric energy are blocked by the problems of fuel supply and the correspondent combustion thereof that produce incalculable damages to the ambient with the recurring danger of the insufficient safety of the nuclear stations and of the destruction of the residuals thereof.

It is the aim of the present invention to eliminate above mentioned disadvantages.

The object of the present invention, as it is characterized in the enclosed claims, solves the problem of the pollution and of the danger of the nuclear stations as it does not make use of any kind of fuel.

The advantages obtained by means of the object according to the present invention mainly consist in the production of 'clean' energy at extremely reduced costs, thus protecting the ambient, in the realization of carrying floating structures resistant to the waves of the sea in areas where there are no spaces on the dry land.

The component of the present invention, consisting of the plant of submerged hydroelectric generating stations, is realized by means of a chamber placed at the bottom of a submerged trellis-work where a

turbine taking water from the outside, makes use of the hydrostatic pressure given by the height of the impending liquid column, which determines the motion of said turbine generating electric energy.

The discharge of the water to the surface takes place making use of the push produced by the turbines and introducing into the discharge tubes compressed air generated by a compressor, in conducts consisting of a series of tubes with reduced diameter, thus realizing an air pump that creates a upward push of the liquid.

The produced electric energy passes, through conducting cables, to the transformation cabin provided on the surface so that it can be sent to the dry land for utilization.

For what concerns the use of the platform as carrying structure as foundation base for bridges, floating touristic villages and other uses, the chamber used for housing the turbine may also be used for the hydrostatic push needed for supporting the load of the foundations so that a force balance may be obtained with appropriate ballasting.

The present invention will be explained more in detail hereinbelow relating to the enclosed

drawings, in which two preferred embodiments are shown.

Figure 1 shows a perspective view of the platform according to the present invention, in which a series of columns 1 are shown connected to a series to horizontal rings 2 and with a spiral ring 3 that surrounds the columns starting from a ring 4, starting point of the iron cables placed in tension by means of a ring 22.

Figure 2 shows a vertical cross view of the platform with the plant for the production of electric energy by means of a chamber 5 (position C) for the housing of a turbine 10 that may be reached through an inlet and outlet chamber 6 for the maintenance through a hatch 47.

The hydraulic power of the turbine will be a function of the product of the hydrostatic column H by the capacity Q.

By means of a distributor 7 adjusted by a gate 8 and protected by a series of gratings 9 the water flows into the propeller turbine 10, and through the aspiration tube diffusor 11 flows over into reservoirs 32 having a dimension according to the need of determining the functioning of a pump using the ram-stroke for rising the water out of the

reservoir up to a level superior to the original one.

Furthermore, the present invention provides the use of an air emulsioning pump, wherein the compressed air is generated by a compressor 25 provided at a surface leves so that, by means of injectors 33 connected to a series of tubes 34 with reduced section, using the Law of Bernoulli and by means of the pressure supplied by the air boxes 35 provided with valves 43 with alternate working and relative gates 44 connected by the bifurcation 45 to the reservoir 32, the outflow of the water to the surface is obtained without weighing onto the turbine 10.

The chamber 5 housing the turbine and the pumps is connected, for the air exchange, to the column 19 for the inlet and to the column 16 for the outlet. The inlet to chamber 5 takes places by means of a hatch 46 passing through chamber 6 from the external hatch 47. This inlet is used for the passage of eventual encumbersome spare parts.

For the usual maintenance the passage through the equipped column 48 will be used.

The electric cables 14 coming from the turbine 10, connected to transformer 21 of chamber 20 (in

position B), are sending, together with the insulators 29 and lines 30, the produced electric energy to the dry land for the utilization thereof.

The floating and the stability to the waves are realized, according to the variant shown in figure 3, by means of a ring 17 provided on the water surface and that is much larger than the ring of the cylinder of columns 1.

Said ring 17 is radially connected by tubes 18 to columns 19 that support chamber 20, placed in an elevated position so as to realize an obstacle to the waves, and said columns end up in a ring 22 that is a drafting point of the iron cables.

Furthermore, figure 2 shows the support of covering 23 of transparent synthetical material, provided with an air opening 24, a door 28, a staircase 27 with a gangway 26 and a docking point for the boats carrying the maintenance personnel. The radial tubes 18 are being reinforced by means of connections 31 to the series of columns 1 and 19 for a greater solidity (see position A).

Figure 4 shows in reduced scale the transformation chamber 20 supported by a projection of the series of columns 1 and 19 (position B of figure 2): in particular, transformer 21, compressor 25 with air

emitting tubes 15, the inlet of electric cables 14 and the insulators 29 with the lines 30, and the inlet door 28 are shown.

Figure 5 shows, in reduced scale, a plant view of the chamber 5 of the turbine placed in position C of the platform, realized between the series of columns 1 and rings 2 and 4.

Figure 6 shows in a perspective view and in reduced scale, the platform used like a carrying structure for the foundation basis of bridges, floating touristic villages or other uses. Said platform makes use of the hydrostatic push for the foundation base of floating constructions and is obtained like the platform shown in figure 1, with the following variants:

1) the chamber 5 and 6 of the turbines is replaced by a chamber 42 having the function of supplying a hydrostatic push,

2) an appropriate ballasting provides a static balance between the loading forces and the hydrostatic push.

By means of oleodyna ic small pistons 37, alternatively connected by means of tubes, columns 36 balance the wave motion. The upper part 38 unites the columns in one single point to the spherical joint 39 and the spherical cover 40 that transmits

the forces or loads to the barycentre by means of a beam 41 for the connection to the other platforms composing the foundation base for structures of bridges, touristic villages or other uses of floating constructions.
