    [0001] IMPROVED MECHANICAL-HYDRAULIC DEVICE FOR ENERGY RECOVERY
    [0002]
    [0003] The present invention consists of a mechanical-hydraulic energy generating device that takes advantage of the hydrostatic thrust that occurs on a set of bodies in a column of fluid, and the free fall of said bodies under the action of gravity.
    [0004]
    [0005] State of the art
    [0006]
    [0007] There are different devices that take advantage of the hydrostatic thrust that occurs on a set of floats in a fluid column, and the fall by gravity of said floats, and obtain from the kinetic energy produced another type of energy, for example, electrical energy .
    [0008]
    [0009] Document GB 2421768 A describes a device comprising a fluid-filled chamber in which the floats rise due to the hydrostatic thrust produced thereon and a chamber adjacent to this filled with air in which the floats fall by gravity. The problem with this device is that in the intermediate chamber, where the floats pass from the air-filled chamber to the fluid-filled chamber, the floats enter from the bottom, which requires a supply of additional energy, since it is difficult that only by the action of gravity they can have enough momentum to penetrate said chamber. Another problem with the device is that the filling and emptying of the intermediate chamber takes place by means of a complex valve system, which also requires additional energy input. In addition to all the above, when the intermediate chamber is opened, the fluid present in said chamber falls by gravity and it is necessary to supply fluid again to the intermediate chamber through its upper part.
    [0010]
    [0011] US 2014196450 A1 also describes an energy recovery device that takes advantage of the hydrostatic thrust that occurs on a set of floats in a chamber filled with a fluid, and the fall by gravity of said floats in an adjoining chamber filled with air. Between the two mentioned chambers there is an intermediate chamber that is always full of fluid, making it difficult for floats to penetrate into said chamber solely by gravity, being necessary to apply a force on said floats so that they penetrate into the intermediate chamber.
    [0012]
    [0013] CN 1743663 A, for its part, describes an energy recovery device that takes advantage of the hydrostatic thrust that occurs on a set of floats in a chamber filled with a fluid, and the fall by gravity of said floats in an adjacent chamber filled with air. In this device, there is an intermediate chamber between the two mentioned chambers that is filled with a fluid present in a first tank, and empties into another second tank, making it necessary to pump means between both tanks to recover said fluid, which entails a additional energy expenditure. Furthermore, the system takes up a lot of space due to the presence of the mentioned deposits.
    [0014]
    [0015] Document CA 2485929 A1 describes an energy recovery device that takes advantage of the hydrostatic thrust that occurs on a set of floats in a chamber filled with a fluid, and the fall by gravity of said floats in an adjoining chamber filled with air. The passage of the floats from the air-filled chamber to the fluid-filled chamber occurs through a wheel that has cavities on its perimeter in which the floats are housed, the perimeter of the wheel sealing the passage between both chambers. The problem with this device is that it is difficult for the movement of the floats to overcome the friction produced between the wheel and the duct in which it is located, and also when one of the cavities comes into contact with the fluid-filled chamber, it is lost part of it, which requires a continuous supply of fluid to the chamber.
    [0016]
    [0017] The present invention describes an energy recovery device that takes advantage of the hydrostatic thrust that occurs on a set of floats in a chamber filled with a fluid, and the fall by gravity of said floats in an adjoining chamber filled with air, and that presents an intermediate chamber in which the floats can enter without the need for additional energy input, in which the energy used to empty the intermediate chamber is recovered, and in which the system is simpler and has less number of valves and actuators than the devices described above, the necessary energy input being less, so the device's efficiency is greater.
    [0018] Explanation of the invention
    [0019]
    [0020] The present invention consists of a device for energy recovery that is made up of the following elements:
    [0021]
    [0022] • A set of floats.
    [0023] • A first chamber or tank open in its upper part and closed in its lower part by a first gate, said first chamber being filled with a liquid fluid (from this point on, when reference is made in this specification to a fluid it refers to a liquid fluid). The floats enter said chamber through the lower gate and experience an upward thrust equal to the weight of the displaced fluid, according to the Archimedean principle.
    [0024] Any fluid whose density is greater than the density of the floats is suitable for the present invention.
    [0025] • A second chamber or sector open at the top and closed at the bottom by a second gate. The floats penetrate said second chamber through the upper part and move to the lower part in free fall due to the action of gravity.
    [0026] • An intermediate chamber arranged at the bottom of the first and second chambers, said intermediate chamber communicating with the first chamber through the first gate, and said intermediate chamber communicating with the second chamber through the second gate. The first gate is in a higher position than the second gate. The intermediate chamber comprises a communication conduit with the first chamber provided with a first valve, and further comprises an atmospheric intake in its upper part regulated in turn with a second valve.
    [0027] • A fluid extraction element present in the intermediate chamber. Said element extracts the fluid present in the intermediate chamber, stores it, and subsequently reintroduces said fluid into the intermediate chamber. The energy used in the extraction of the fluid is accumulated in this extraction device, and the impulsion of said fluid towards the intermediate chamber is carried out without any additional energy contribution.
    [0028] • Optionally, a float braking / separation element arranged in the lower part of the second chamber.
    [0029] • Optionally, a push element arranged on the second gate.
    [0030] The operation of the device is explained below. At rest, the first and second gates are closed and the first and second valves are closed, and the intermediate chamber is filled with fluid.
    [0031]
    [0032] Then the second valve opens and the second gate opens. The extraction device then extracts the fluid present in the intermediate chamber, and a float falls by gravity (or assisted by the push element) from the second chamber to the intermediate chamber. The braking element prevents more than one float from falling from the second chamber to the intermediate chamber when the fluid has been withdrawn from said intermediate chamber.
    [0033]
    [0034] Then, the fluid withdrawn by the extraction element is again driven into the intermediate chamber. Sequentially or simultaneously, the second gate is closed.
    [0035]
    [0036] When the extraction element extracts the fluid present in the intermediate chamber, said intermediate chamber fills with air due to the fact that the second valve is open. When the fluid is pushed back into the chamber, the excess air is expelled outside through the atmospheric intake. The atmospheric intake is intended to comprise an element such as a suction cup that allows air to pass both inward and outward but prevents the fluid from escaping.
    [0037]
    [0038] The second valve is then closed. The float present in the intermediate chamber is moved to a position below the first gate, because it is at a higher distance than the second gate. At this time the first valve opens, thereby balancing the pressures of the first chamber and the intermediate chamber. Once the pressure between the first chamber and the intermediate chamber has been balanced, the first gate opens and the float present in the intermediate chamber along the first chamber occurs due to hydrostatic thrust. The remaining fluid (which does not fit in the intermediate chamber due to the volume occupied by the float present in it) present in the extraction element is supplied to the intermediate chamber as the float passes from the intermediate chamber to the first chamber.
    [0039]
    [0040] The second chamber and the first chamber are connected by the upper part, normally the upper part of the first chamber being higher than the upper part of the second chamber, so that the floats that reach the upper part of the first chamber are displace the upper part of the second chamber due to the slope between the upper part of both chambers.
    [0041]
    [0042] Normally, in the first chamber there is not only a float, but a stack of floats are found, so that when a float passes from the intermediate chamber to the first chamber, it pushes the float stack and causes the float to be present at the top drop towards the second chamber.
    [0043]
    [0044] Finally, the first gate and the first valve are closed, and the process begins again.
    [0045]
    [0046] The energy is obtained thanks to the movement of the floats throughout the device, for example, by means of generators activated by paddles to which the movement of the floats transmits, by means of coils arranged around the first and second chambers in which current is induced by the presence of a magnet in each float, or any suitable method of obtaining energy from kinetic energy.

    [0074] Description of the preferred embodiments of the invention
    [0075]
    [0076] In view of the aforementioned figures, and according to the numbering adopted, a preferred embodiment of the invention can be seen in them, which comprises the parts and elements indicated and described in detail below.
    [0077]
    [0078] Thus, as seen in Figure 1, a possible preferred embodiment of the mechanical-hydraulic energy recovery device essentially comprises the following elements:
    [0079]
    [0080] • A set of floats (9).
    [0081] • A first chamber (7) filled with a fluid, for example water, open at its top and closed at its bottom by a first gate (1).
    [0082] • A second chamber (10) open at the top and closed at the bottom by a second gate (2).
    [0083] • An intermediate chamber (8) arranged at the bottom of the first chamber (7) and the second chamber (10), which communicates with the first chamber (7) through the first gate (1) and with the second chamber (10) through the second gate (2), in which the first gate (1) is in a higher position than the second gate (2). According to an embodiment option, the second gate (2) is inclined towards the first gate (1).
    [0084] • A communication conduit (60) between the intermediate chamber (8) and the first chamber (1) provided with a first valve (6).
    [0085] • An atmospheric intake (50) in its upper part provided with a second valve (5). The atmospheric intake also includes a suction cup (51) that allows the passage of air in both directions, but prevents the passage of fluid through it to the outside.
    [0086] • An extraction element (3), in the intermediate chamber, comprising a piston, causing the piston to move along a cylindrical duct to suck or expel the water present in the intermediate chamber.
    [0087] • A braking element (11) arranged at the bottom of the second chamber (10). This braking element serves as a regulator for the passage of floats from the second chamber (10) to the intermediate chamber (8).
    [0088] • Optionally a thrust element (4) arranged on the second gate (2).
    [0089] At the beginning of each operating cycle, as shown in Figure 1, the first gate (1) and the second compound (2) are closed, as well as the first valve (6) and the second valve (5). One set of floats (9) are in a stack in the first chamber (7) immersed in the fluid, and another set of floats (9) are in the second chamber (10), in which there is no fluid, and they are retained by the braking element (11).
    [0090]
    [0091] Next, the second valve (5) is opened and the extraction element (3) is actuated and extracts the fluid present in the intermediate chamber (8), as shown in Figure 2, occupying the volume displaced by the extracted fluid by means of air obtained through the atmospheric intake (50).
    [0092]
    [0093] The second gate (2) is then opened, and one float (since the braking element retains the other floats present in the second chamber) is allowed to pass from the second chamber (10) to the intermediate chamber (8) by the action of gravity. The push element (4) is then activated, as shown in Figure 3, to push the float (9) and assist it in its passage through the second gate (2), in case the size of the gate and the float is similar, and a small pushing force is required for the float to pass through the gate.
    [0094]
    [0095] Then, as shown in Figure 4, the extraction element (3) is actuated and pushes the fluid inside it to propel it back into the intermediate chamber (8). Once the intermediate chamber (8) has been filled with fluid, the second valve (5) is closed and the float (9) present in said intermediate chamber (8) moves towards the first gate (1) due to the difference in existing height between both gates. To facilitate movement from the second gate to the first gate, the section between the two gates, or the second gate (2), or both can be inclined towards the first gate (1). In the extraction element (3) the part of fluid that does not fit in the intermediate chamber remains due to the volume occupied by the float (9) present in it.
    [0096]
    [0097] At this time, as shown in Figure 5, the first valve (6) opens, thereby balancing the pressures of the first chamber (7) and the intermediate chamber (8). Once the pressure has been balanced, the first gate (1) opens and the float (9) present in the intermediate chamber (8) occurs along the first chamber (7) due to the hydrostatic thrust. The float pushes the stack of floats present in the first chamber (7), so that the float present in the upper part leaves the first chamber (7) and moves to the second chamber (10) thanks to the inclined section arranged in the upper part between both chambers. Fluid Remaining present in the extraction element (3) is supplied to the intermediate chamber (8) as the float (9) passes from the intermediate chamber (8) to the first chamber (7).
    [0098]
    [0099] Finally, the first gate (1) and the first valve (6) are closed, and the process begins again.
    [0100]
    [0101] The energy is obtained thanks to the movement of the floats throughout the device, for example, by means of generators activated by paddles to which the movement of the floats (9) transmits, by means of coils arranged around the first and second chambers in which induces current by the presence of a magnet in each float, or any suitable method of obtaining energy from kinetic energy.
