Abstract
The present invention consists of a system capable of producing energy by transforming the kinetic energy of a fluid into mechanical and/or electrical energy, constituted by at least two pistons (6) that alternately move inside two chambers (1), thanks to the fluid they contain as well as to the shift of a mass (16) connected to them. When said pistons (6) move, they push the water contained in the gap between them and said chambers (1), into a tank (4) from which the water falls with a hydrostatic drop that powers the turbine (5). The water fallen down is reclaimed and resent inside the chambers, so that the cycle starts again.
Description
SYSTEM AND METHOD FOR THE TRANSFORMATION OF POTENTIAL
AND KINETIC ENERGY OF A
FLUID
Description Technical Field
The present invention concerns the technical sector relative to the production of electrical and/or mechanical energy using the fall of water or other fluid, also called hydrostatic drop. This invention concerns the technical sector relative to the realization of systems for the production of energy and to the realization of equipments implementing these systems.
Background Art
There exist so far systems for the generation of energy that use the fall of water to activate a turbine that then transforms kinetic energy into electrical energy.
In order to implement these systems hydroelectric plants are built. In brief, it's known that a hydroelectric plant is constituted by a process of collecting waters, by a process of carrying them and by machineries that transforms hydraulic energy into mechanical energy, where the latter is transformed by known systems into electrical energy.
In order to better understand the importance of this sector, it's useful to assess the percentage of energy produced by this specific system, despite the various technical methods used to constantly improve the efficacy of the power stations .
It's statistically proved that hydraulic energy approximately represents ^ of the energy produced in the world and, in the last years, is progressively becoming much more important.
Unfortunately, every expert of this field knows that any system for producing energy, in any form, capable of reproducing itself, cannot be reproduced, therefore it's considered impossible, because of energy dispersals, either caused by mechanical frictions, ' heat dispersions or
other, but that inevitably make a system however unable of regenerating itself. Succeeding in obtaining this, would mean in fact obtaining the i
"perpetual motion", which means a hypothetical movement that proceeds equivalent to itself without changes in time and space and without the aid of any internal or external source of energy.
A motion of this kind, even if approximated within certain limits (for example by the movement of objects on reduced friction surfaces or even better by the movement of the planets) , is however excluded from the physical laws nowadays commonly accepted, in particular from the thermodynamic principles.
In theory, there exist two types of perpetual motion. The first one is realized by a machinery that produces more energy than the energy it spends to work; this machinery, once started, would work forever, supplying itself, ■ evidently violating the principle bf conservation of energy (first law of thermodynamics); many proposals for these machines use magnets as form of energy from void and employ systems with no friction. If these systems, theoretically, could be able to regenerate their motion, still it's not physically possible to extract from them free energy. The second type should be able to transform inside the heat extracted from a single source at constant working temperature, violating the second law of thermodynamics: a practical example is a ship capable of moving forwards extracting heat from the water of sea, transforming this heat into kinetic energy necessary for its proceeding, without releasing any part of heat to the colder source (water of sea) .
In this hypothetical case, the first law of thermodynamics would be satisfied; nowadays, the second principle is considered as a consequence of statistical mechanics, therefore its validity is considered simply probable.
Consequently, violations of the second law are possible, but with very small probability.
The invention at issue does not realize a perpetual motion, but a system- capable of realizing a self-supplying device, recycling the same fluid, wherein the energy necessary to implement it is extremely reduced, therefore allowing the power station to be effective in the ratio energy produced/energy necessary for its working.
Besides, the present invention avoids other basic drawbacks of the specific sector from which energy must result.
It' s obvious that the main limit for the building of a hydroelectric plant is the geographical conformation of the ground, as ' at least one of the following features is necessary: drop of water from relevant heights, or alternatively large volumes of water. These different situations, however nowadays necessary, are differently employed according to their characteristics by suitable electro-mechanical systems for this purpose.
Therefore, the two above-mentioned features require however a constant and considerable water supply. Which necessarily limits the places for the installation of the plant, excluding many geographical spaces.
The existing equipments use only current water, except for small and not relevant apparatus of energy reclamation, and do not employ any sort of system mainly directed to the maximum efficiency, by means of various transferring systems or other, as nowadays, with the current building concepts, the adopted process is considered advantageous.
Disclosure of invention
The present invention aims at avoiding these and other drawbacks, providing a complex system based on the principle of the communicating vessels, supporting the movements and the distributions of the forces in the various phases in .self-supplying mode. However, this complex system aims, with the use of precise building dimensions and suitable materials, at recreating
through continuous decanting the same initial situation and, by same decanting, obtaining a constant supply of water and a sufficient hydrostatic drop for the transformation of kinetic energy into mechanical energy, for example for the activation of the turbine, the most effective for this purpose, for the production of electrical energy.
However, this system can be installed in any geographical place, overcoming the limit of some grounds, as in practice it needs a limited continuous supply, being per se autonomous using in theory the same quantity of water. In addition, despite the lack of materials to annul the dispersion of friction and energy heat, this invention however has, with the building concept we're going to describe, a perfect efficiency and a restricted need of external or internal energy injections, possibly necessary to complete the cycle or exclusively to start it.
The present invention has the following advantages. It allows the installation of a hydroelectric plant even where the natural geographical conformation of the ground is not suitable, thanks to the employed system that use the same fluid repeatedly, resending it in cycle by the same system, so avoiding the need of a constant hydrodynamic drop nowadays obtained by dams, channels or other, to be able to sufficiently power a turbine. This system, thanks to its dynamic concept, permits to produce energy with higher efficacy than the existing devices, being self- supplying. This system, thanks to its characteristics, can be realized on any geographical conformation, regardless of the traditional conditions (rivers, falls, dams) necessary for the working of any hydroelectric plant, as this system is indeed a closed circuit, reusing the same fluid and requiring further injections only in case of possible leaks. In practice, this invention consists <^f a system, based on the communicating vessels, aimed at recreating, through continuous decanting, the same initial situation and, by • same decanting and by means of
mechanical aids using inertia and balancing, obtaining a constant supply of water and a sufficient hydrostatic drop for the activation of the turbine for the production of electrical energy.
Reduced to its essential structure and with reference to the figures of the enclose drawings, a system for the production of energy using a turbine, or other suitable means, for the transformation of kinetic energy into mechanical and/or electrical energy, according to the present invention, comprises :
— means to powerfully charge the system and use the fall of a fluid, consisting of a tank (4), placed at suitable level necessary for the hydrodynamic drop that acts on a turbine or other suitable means (5), found at the base of a connecting collector, located below said tank (4);
— means to dynamically activate the system, consisting of at least two hollow pistons (2) having external shape corresponding to the internal shape of at least two chambers (1) holding them, but with small sizes, creating between piston (2) and chamber (1) a gap containing appropriate volume of fluid; when said pistons alternately move, they will pour the fluid contained in the chambers into the tank {4) and then let it fall towards the turbine or other suitable means (5) ;
— means to move said pistons (2) through their weight, consisting of the fluid they alternately contain and of the push exerted by a mass (16) i oscillating along an arc (15) over the system and connected to said at least two pistons (2) ;
— means to reclaim the fluid activating the turbine or other suitable means (5) , consisting of lower collectors (10) , transferring, through servo-controlled valves (12) or other suitable means, the fluid inside the chambers (1) holding the pistons (2) .
This system comprises an upper tank (4) connected two said at least two hollow chambers (1) by means of two or more upper collectors (7), close to the fluid of the chambers, so that this fluid moves from the chamber (1) to the tank (4) causing the hydrostatic drop for the turbine.
This system comprises a lower tank (4a) connected to said at least two hollow chambers (1) by means of two or more* lower collectors (10), placed below the turbine (5) , so as to completely reclaim the water fallen down.
Said at least two chambers (1) are positioned with relative internal pistons in opposite way compared to a middle axis. Between the two chambers there is the tank (4) for collecting the fluid.
The level the tank is placed compared to the vertical position of the turbine or other suitable means (5) represents therefore the "hydrostatic drop" (H), necessary for the working of the same turbine, placed under the tank.
The tank (4) through a conduit supplies the turbine or other suitable means
(5) , specifically placed at suitable drop.
The fluid crossing the turbine or other suitable means (5) is transferred i in at least two conduits (10) that, by means of servo-controlled valves
(12), pour alternately the liquid into the two chambers, therefore, outside the two hollow pistons.
This system comprises two pistons (2) hollow inside, held into the chambers
(1), closed at their base by suitable gate (3), inside which a fluid is poured from the moment the piston is at its top dead centre through conduits (6) whose flow is regulated by the respective servo-controlled valve or similar means (8) . When the piston is filled, its greater weight causes it go down.
Said pistons also include at their base a gate (3), or other similar means, so that when a piston goes down on one side due to its greater weight caused by the fluid it contains and to the taction of the oscillating mass
(16) , on the other side the symmetrical piston is opened at its base and emptied of the fluid it contains, so as to make it lighter and go up, causing in its turn the opposite cylinder go down.
This system comprises means to pour a fluid into the pistons (2) at every cycle, consisting of at least two conduits (6), regulated by servo- controlled valves (8) , connecting the tank (4) to the same pistons (2) . This system comprises means to completely remove the water inside the pistons (2), so facilitating their total run, consisting of a servo- controlled gate (3), placed at the base of each piston (2) .
Conveniently, the two pistons (2) are connected each other by means of a sort of walking beam (13) .
This system comprises means to dynamically tie the two pistons (2), consisting of a walking beam (13) , equipped with rail with reversed arc (15), where an oscillating mass (16) slides.
Thanks to said walking beam, once the system has started, possibly facilitated from the inside or outside by any means (17), the mass (16) shifts on one side (for example towards right) , facilitating in this way the raising of the left piston (2), which in that phase will be full of fluid inside.
Said walking beam (13) has a central pivot (14) and its ends are connected by means of piston rods, or any other effective method, to the two pistons (2) .
Conveniently, the motion of the pistons inside the chambers will be guided, by any suitable method, so as to make it suited to the needs of the system. The movement of the walking beam (13) causes the relative reciprocating raising and falling of the two pistons (2) .
The walking beam is equipped with rail with reversed arc (15), with negative arrow (f) . On the rail there is an oscillating mass (16) .
The raising of the left piston (2) and the shift of the mass (16) towards right, make the right piston (2), in this phase full of fluid, go down; in this way it pushes up the fluid contained inside the respective chamber (1) . This fluid is poured into the central tank (4) and entails the hydraulic drop that moves the turbine or other suitable means (5) . In the meantime, the left piston (2) is emptied, thanks to the opening of its base gate (3), in order to complete the cycle.
Simultaneously, the fluid that has powered the turbine, by the activation of the valve (12) on the conduit (10), is poured into the left chamber (lsx) to get its content to the desired level.
Then, the left piston raises and when it reaches its top dead centre, through the conduit (6), it receives the fluid from the tank (4), by means of the activation of the servo-controlled valve (8) , so it fills up and goes down, starting a new cycle opposite to the previous one. This descent causes the shift of the mass (16) along the arc (15). The right piston (2dx) is emptied, so it's lighter and raises, allowing the mass (16) to definitively shift towards left; in this way, it completes its run pushed by its weight and causes the left piston (2sx) go down, moving the fluid inside its respective chamber and*pouring it again into the tank (4), thus repeating the above-described cycle.
The dimension of this system will entail the transfer of a quantity of water sufficient for the activation of a turbine and for the reciprocating load of the pistons .
Conveniently, by different dimension of the system, we'll get greater hydrostatic drops increasing the heights of the basic component in order to have a larger gap between tank and turbine, or get a greater fluid supply increasing the sizes of the basic component or adding more components, so permitting the appropriate use of various types of turbine.
The dimension of this system will have to permit the transfer of the above- cited sufficient, quantity of water to make the turbine continuously turn. In a practical example, this system has the following dimensions: As regards pistons and cylindrical chambers: Height of chamber - piston m 10 Internal diameter of chamber m 1 External diameter of piston m 0.9 As regards the water contained into the chamber: π . r2. h/2 = 3.14.0,52.5 = 3,925 m3 = 3.925 litres
As regards the internal volume of the chamber : π . r2. h = 3.14 . 0,52. 10 = 7,850 m3 = 7.850 litres
As regards the volume filled by the piston dipped in the water: π . r2. h = 3.14.0,452.10 = 6,374 m3 = 6.374 litres
As ■ regards the quantity of water transferred into the connecting conduit with the immersion of the piston:
Water into the chamber - (volume of chamber - volume of piston) =
= 3.925 - (7.850 - 6.374) = 2.449 litres
As regards the quantity of water necessary for the hypothetical turbine: 1000 litres As regards the quantity of water available when the piston fills up:
Quantity of water pumped - Quantity of water available for the turbine = 2.449 - 1000 = 1.449 litres
As regards the weight of the oscillating mass necessary to prevail the Archimedean principle undergone by the piston:
-Volume of the piston dipped - Quantify of water available for the piston = 6.374 - 1.449 =4.925 kg
Method for the generation of energy using the kinetic energy of the water, characterized in that, given a system constituted according to one or more of the above-described characteristics, it comprises the following phases:
1. closure of the base gate (3) of the raised piston (in this example, the left piston) and filling of the same piston (2sx) thanks to the opening of the valve (8) ;
2. consequent descent of said piston and simultaneous raising of the opposite piston (2dx) that is lower, full and with the gate (3) closed;
3. rotation of the walking beam (13) around the pivot (14), slope of the rail (15) and sliding of the oscillating mass (16) towards left, possibly facilitated by any internal or external mechanism (17);
4. descent of the piston initially raised (2sx) , which moves the fluid into the respective chamber (lsx) , so that the volume of moved water raises and, passing the upper edge of the chamber (lsx) , pours through the conduit (7) into the tank (4);
5. opening of the gate (3) of the right piston (2dx) , now in raising phase, so as to unload it and make it definitively lighter, allowing it to go up and allowing the left piston to reach its bottom dead centre and pump the entire volume of the fluid necessary for the working of the equipment;
6. simultaneously, the fluid that has powered the turbine, by the activation of the valve (12) on the conduit (10), is poured into the left chamber (lsx) to get its content to the desired level;
7. reaching of a condition exactly opposite to the initial one and repetition of the cycle following the previous phases.
Conveniently, utilizing the principle of the communicating vessels, the quantity of fluid for the hydraulic drop is exclusively a part of the same fluid necessary for the working of this system. As a matter of fact, the remaining portion is only a transmitter of the motion as well as any
hydraulic fluid passing through the actuators controlled by suitable remote consoles .
Conveniently, the excess of water pumped by the left piston (2sx) is available for the following load of the right piston (2dx) , in order to ensure the start of a new cycle.
The current position of the system is actually the opposite to the starting one, with the same' distribution of fluid and with the oscillating mass (16) on the left side, therefore dynamically charged to affect the following cycle .
Conveniently, in the initial condition, the tank (4) and all the connecting conduits (6) and (10) are full.
Conveniently, in the position of phase 1, when the walking beam (13) is totally sloping on one side, for example on the right, with the oscillating mass (16) shifted at the end of this side of the rail (15) , the latter takes in its gradual bend a horizontal position (OR) , therefore balanced in friction in the specific moment.
Conveniently, in the position of phase 1, the first left chamber (lsx) is full of a volume of fluid at least equal to the height of the run of the piston, while the right chamber (ldx) in this moment is full at the edge for decanting.
In practice, the manufacturing details may however vary as regards shape, size, position of elements and type of materials used, but still remain within the range of the idea proposed as a solution and consequently within the limits of the protection granted by this patent for invention.
Brief description of drawings
The enclosed drawings schematically depict the system at issue, as practical but not restrictive examples of thi^s invention.
Fig. 1 shows the basic component of the equipment, constituted by two chambers of any section (1), calculated to be approximately the double high
of the hydrostatic drop to obtain. They are obviously hollow, open at the top and mechanically structured so as to contain water without leaks.
Inside each chamber (1) a mobile structure is inserted, called piston (2), whose external shape is geometrically equivalent to the one of the chambers, slightly smaller bur longer, hollow inside and closed at the base with a "gate" (3) that can be automatically opened by any known system. The two chambers are positioned with relative internal pistons in opposite way compared to a middle axis, where the tank (4) collecting the water is placed. The level the tank is placed compared to the vertical position of the turbine (5), represents therefore the "hydrostatic drop" (H), necessary for the working of the same turbine.
Tank (4) and chambers (1) are connected by means of collectors (7), of suitable section and placed at appropriate level.
The tank is also provided with further collectors (6), called "loading conduits", which power the mobile pistons (2) at suitable height.
The connection between collectors (6) and inside of the pistons (2) occurs at suitable height thanks to a further collector (6), telescopic or realized by any other method, which guarantees a possible constant connection with the piston (2) constituting single conduit; these conduits are obviously regulated by servo-controlled valves (8) that, activated by suitable ' systems, permit the movement of the water in the right times and with the appropriate flow.
The tank is connected to the turbine, placed at suitable drop, by means of a conduit equipped with any method for regulating the flov*.
The water crossing the turbine is transferred into two conduits (10) that, by means of further servo-controlled valves (12), pour the liquid into the two chambers, therefore out of the two pistons.
For completing this hydraulic system, a mechanical system is positioned above, constituted by a walking beam (13), which has a central pivot (14)
and its ends are connected by means of piston rods, or any other effective method, to the two pistons (2) . Obviously, the motion of the pistons inside the chambers will be guided, by any suitable method, so as to make it suited to the needs of the system. We specify that this representation is intentionally schematic and the mechanical parts, obtained by any known manufacturing concept, satisfy the working needs of the depicted dynamic. v
Therefore, the movement of the walking beam (13) causes the relative reciprocating raising and falling of the two pistons (2) .
The walking beam is equipped with rail with reversed arc (15), with negative arrow (f) . On the rail there is an oscillating mass (16) that, as we'll see in the dynamics, will facilitate the working of this system.
The dynamic of the system is hereafter described in the next figures.
Fig. 2 shows the starting phase of the system that can be facilitated, when necessary, by a starting mechanism (17) in such a position that can act on the system. The initial condition entails the physical state of the system wherein, in this example, the walking beam (13) is totally sloping towards right with the oscillating mass (16) shifted at the end of this side of the rail (15) ; the structural mechanics of the particular assembling of rail
(15) and oscillating mass (16) is conceived so that, in this condition, the rail takes in its gradual bend a horizontal position (OR) , therefore balanced in friction in the specific moment.
Necessarily, as mechanicall-y dependent consequence, the opposite piston
(2sx) .is completely lifted, emptied of liquids and' has the lower gate (3) open.
On the contrary, the right piston (2dx) is completely down and has the gate
(3) closed.
The tank (4) and all the connecting conduits (6) and (10) are full.
The first chamber (lsx) is full of a volume -of fluid at least equal to the height of the run of the piston (top dead centre of lsx) , while the second chamber (Idx) in this moment is full at the edge for decanting. Fig. 3 shows the first dynamic operation where the base gate (3) of the left piston (2sx) closes and the same piston fills up thanks to the opening of the respective valve (8), causing as primary condition the descent of the cylinder (2sx) , possibly facilitated by any starting mechanism (17). Consequently, the walking beam (13) begins its rotation around the pivot (14), and the rail (15) connected to it takes a slope that makes the oscillating mass (16) slide towards left.
During this phase, the left piston (2sx) , which goes down, moves the water in the chamber of the respective cylinder (lsx) . Fig. 4 shows the next step where the volume of moved water raises and, passing the upper edge of the chamber (lsx), pours through the conduit (7) into the tank (4) . At appropriate moment of the descent of the left piston (2sx) towards its bottom dead centre, the base gate (3) of the right piston (2dx) automatically opens, so as to unload the same piston and make it definitively lighter, allowing the left piston to reach its bottom dead, centre and pump the entire volume of the water necessary for the working of the equipment .
As a matter of fact, utilizing the principle of the communicating vessels, the quantity of fluid for the hydraulic drop is exclusively a part of the same fluid necessary for the working of this system, while the remaining portion is only a transmitter of the motion -as well as any hydraulic fluid passing through the actuators controlled by suitable remote consoles. Fig. 5 shows the last phase of this cycle where a part of the water from the tank (4) reaches the turbine (5) and then adds to the content of the right chamber (Idx) .
Actually, thanks to the tank (4), we get a constant supply for the activation of the turbine during the entire working of the system.
The excess of water pumped by the left piston (2sx) is available for the following load of the right piston (2dx) , in order to ensure the start of a new cycle.
The current position of the system (Fig. 5) is actually the opposite to the starting one, with the same distribution of fluid and with the oscillating mass (16) on the opposite side, therefore dynamically charged to affect the following cycle.
