Description

TITLE

A HYDRAULIC SYSTEM FOR THE PRODUCTION OF ENERGY

Technical field

The present invention concerns the technical field relative to the hydraulic systems for the production of energy .

In particular, the invention refers to an innovative hydraulic system that is particularly simple from the structural point of view and is a high-performance one.

Background art

Systems for the production of energy have long been known, and they can take advantage of the motion of water, of wind or of the solar energy.

A system that is particularly functional is, for example, described in International patent application WO2012/001466 in the name of the same applicant.

Such a system describes a sucking pump that sucks the liquid, through a sucking conduit, inside a containment chamber. From said containment chamber a vertical conduit departs that serves to form a water column and a series of further conduits that converge on top with a U-junction, in such a way that the same are deviated through said junction downwards. Below such conduits with U-junction current generators are placed that are operated by the water pressure.

The pump, therefore, sucks to keep constant the level of the containment chamber and the water column in the vertical conduit, while, due to a principle of communicating vessels, the water contained in the chamber and in the vertical conduit ascends along the conduits with U-junction to then precipitate downwards once the junction has been overcome, therefore impacting with turbines or generators and producing energy.

This system, which takes advantage of the principle of the communicating vessels, allows, with the use of a pump of modest size that guarantees simply the maintenance of the level of the containment chamber, to produce big quantities of energy.

Nevertheless, this system is structurally complex since it requires conduits that have to foresee U- junctions arranged at specific heights, therefore resulting to be rather cumbersome and complex.

Further, its efficiency is not optimized, since along the vertical conduits the descent motion of the liquid results to be very whirling. The descent speed of the flow is slowed and therefore the rotation speed of the generators is limited.

DJ-^sc osure of invent ion

It is therefore the aim of the present invention to provide an innovative typology of system that solves said technical inconveniences.

In particular, it is the aim of the present invention to provide a hydraulic device which, in a simple and functional manner, allows to obtain a high production of energy and therefore is a high-performance one.

These and other aims are therefore reached with the present hydraulic device in accordance with claim 1.

Such a device (1) comprises:

- A container (2) for the containment of a liquid, said container (2) being placed at a pre-determined height (h) ;

And wherein one or more paths (10) are foreseen that from said container converge downwards in such a way as to allow the flow of the liquid contained in the container by gravity downwards. - In accordance with the invention, said paths (10) are arranged in such a way that said liquid has a gradient of descent comprised within a range between the 25° degrees and the 35° degrees, preferably between the 28° degrees and the 32° degrees, still better of about 30° or 31° degrees.

In the present description, by gradient is meant the angle formed between the path and a vertical to the ground that intersects such a path (as for example shown in figure 2 ) .

It has been surprisingly found out that said range between the 25° and the 32°, still more the value of about 30°, allows the liquid to have a laminar motion, therefore optimizing and increasing its descent speed three times with respect to the case in which its motion is turbulent when, for example, it descends along a vertical conduit.

The increase in speed, naturally, allows the turbines placed below the flow to turn more quickly and produce more quantity of energy.

Further advantages can be deduced from the dependent claims .

Brief description of drawings

Further features and advantages of the present hydraulic device, according to the invention, will result clearer with the description that follows of one of its embodiments, made to illustrate but not to limit, with reference to the annexed drawings, wherein:

Figure 1 represents in an axonometric view a device as per the present invention;

- Figure 2 represents a front view that highlights the angulation of the descent path of the liquid with respect to the wall to which such a path is fixed. Description of some embodiments

With reference to figure 1, the device that is the object of the invention is described in an axonometric view .

Such a device foresees a support base 5 which serves to hold and keep at a pre-determined height from the ground (h) a container 2.

The container 2, of any shape and size, forms a containment volume into which the water is directed (or another liquid) . In fact, the container 2 is like a dyke of containment of the liquid.

As represented with a subtle dotted line, the support base 5 can serve to contain inside it a pump 3 from which to suck the liquid to make it ascend inside the container 2, for example through a conduit 4.

The support base can also have the shape of a reticular frame and anyway, independently of the support base 5, the pump 3 could be placed in any position ideal for the draughting of the liquid and therefore internal or external to said base.

Connected to the container 2 one or more conduits 10 (for example, pipes) are foreseen, which branch off from the container 2 downwards.

In accordance with the invention, as also shown in figure 2, they are placed according to a specific angulat ion .

In particular, the angle formed between the path of the fluid (therefore the longitudinal axis of the conduit 10) and a vertical wall with respect to the ground that intersects such a conduit is comprised within a range between the 25° sexagesimal degrees and the 32° degrees and preferably about 30 degrees or 31° sexagesimal degrees (therefore about n/6 in radians) .

In the present description, therefore, with the term gradient is meant such an angle formed by the path of the fluid and a vertical line to the ground that intersects such a path even if, generally, the true gradient is measured as the angle comprised between the horizontal ground and the conduit (that in the case of a gradient of 30° would result the complementary of value 60°) .

It has been surprisingly found out that the value of such a "gradient" of 30° is precisely the optimal one, therefore the falling motion of the liquid, by gravity, along such a conduit 10, is optimized since a laminar motion, and not turbulent, is obtained.

In particular, the fluid moves, arranging itself in layers that slip one on the other with respect to a condition of turbulent motion.

It has been found out that with respect to a conduit placed vertically with respect to the ground, the descent speed of the liquid increases approximately three times, since the laminar motion favours and optimizes the increase in speed of the liquid itself with respect to a case of turbulent motion.

Optimal results can be obtained also with said angulations comprised between the 25° and the 32°.

Such an increase in speed is therefore exploited to optimize the performance and the production of energy.

As in fact shown in figure 1, below the conduits 10 one or more dynamos 100 or rotating turbines 100 can be placed, which are connected to generators (G) for the production of current.

The turbines can be connected also to batteries that store the energy produced.

The use of more dynamos 100 or turbines can be foreseen, for example, each one placed, for instance, below a respective conduit 10.

Just as a way of example, it has been verified that a pump 3 of two Kw can be used, which delivers sixteen liters of liquid per second, taking such a liquid to a height of twenty-two meters.

The tank 2 on top has been chosen of such a size as to contain 2.000 liters of liquid at a height h of seven meters from the ground.

It has been proved that, in this case, with a height from the ground of seven meters and 2.000 liters of liquid, and using six turbines that are operated by the liquid, the same energy is obtained as the one that would be obtained by taking the liquid to 22 meters and therefore making the most of the pump.

This is so because the laminar motion, thanks to such an angulation, increases significantly the descent speed, about three times with respect to the case of vertical conduit.

In accordance with such a solution, the pump can be exploited at reduced regimes or even very small pumps can be used, obtaining quantities of energy that would be obtained with the use of pumps three times more powerful.
