Description

UNDIMOTRIC ENERGY TRANSFORMATION DEVICE IN ELECTRICAL ENERGY.

D E S C R I P C I Ó N

OBJECT OF THE INVENTION

The present specification refers to a PCT request regarding the generation of electrical energy through the transformation of wave energy.

Wave energy, that is, produced by the movement of the waves, is one of the most promising sources of renewable energy for countries with sea coast

FIELD OF THE INVENTION

This invention has its application within the sector of the generation of electrical energy by means of renewable energies and also within the industrial sector of machinery manufacturing for use in marine environments.

BACKGROUND OF THE INVENTION

The development and use of wave energy is still under study and is in the expansion phase.

At present the existence of some devices and some patents is known in relation to the issue at hand, but in no case the Solutions provided are similar to those described herein.

Scotland has been the place where studies on the transformation of this type of energy have been developed most due to the strong waves that receive its coasts and the important scientific and industrial infrastructure.

But where an artifact of these characteristics was first installed was in Portugal. (1998) Known as Pelamis (because of its resemblance to a sea snake "pelamis platurus") it is a floating and flexible device, installed on the high seas and that several devices can be connected together and send the electrical energy generated to the shore by middle of a long cable.

The union between the devices is one of the weak points of this system.

In addition, the very existence of the long cable, with the losses that it entails, makes its performance not very effective, even considering that it is estimated that thirty connected devices could supply approximately 20,000 homes with average European consumption.

Regarding the patents that can be considered closer to the one in question, two can be mentioned:

DI- As the first document we have the Thai patent: FI2001102620012086 by Rauno Koivusaari Requested in favor of AW-ENERGY OY on October 26, 2001.

For "Wave power machine"

The procedure described is characterized by the use of a plate located at the bottom of a raft of water, and driving the plate by the thrust of the waves that are driven by the bottom, which means a transformation of kinetic energy.

Obviously this procedure has nothing to do with the patent at hand, as we will see later.

D.2.- As a second document we have the following European patent:

E.P-E02770020, for "A procedure to use wave energy"

Obviously this procedure also has nothing to do with the patent at hand, as we will see later.

There are also certain devices in the experimentation phase and some others already implemented that define the state of the art, in relation to but with notable differences.

D.3.- We refer to the "OPT" technology devices that use a high sea buoy to generate the "OPT" Power Buoy wave.

That is not directly related to the invention recommended D.4.- We can also cite as a background the converter device "Wavedragon" (The dragon of the waves), which is a large floating device, designed to capture and concentrate waves.

The waves climb a ramp to a raised tank through the arms of the platform, there the collected water rotates the installed turbines.

Obviously they have nothing to do with the system recommended in the invention at hand.

D.5.- And as a last background, we can cite the device "Archimedes Wave Swing (" Wave Oscillator of Archimedes "), which is not directly related to the invention that concerns us since it is a large air chamber installed on the bottom of the sea. It obviously does not use the surface wave for power generation.

Therefore we have seen that there are varied attempts to use wave force, but all of them different from those recommended in the present invention, which describes a different device, more elaborate, better performance and cheaper maintenance, being also more reliable due to the systems and materials from which it is manufactured, not knowing on the part of the applicant the existence at present of an invention that is endowed with the characteristics described herein. DESCRIPTION OF THE INVENTION

One of the characteristic properties of the waves is their ability to travel over great distances with hardly any loss of energy, so the energy generated anywhere in the ocean ends at the continental edge.

In this way, the energy of the waves is concentrated on the coasts, which is where the invention we advocate is most effective and whose main characteristics are as follows.

The device for transforming wave energy into electrical energy that the invention advocates is constituted by the following main assemblies:

A.- Set of main movement generation buoys

B.- Set of axles and gears of transformation of the main movement into electrical energy

C- Set of deposits and fixing weights at a certain depth of the entire device,

D.- Tension and tension maintenance set of the Device at the appropriate depth

E.- Safety set and output of the main power cable. And each of these sets consists of the following main elements:

A.- Set of buoys generating the main movement:

It is constituted by:

Main buoy of movement, conformed by a buoy-floating of great size and in that that distinguish some fins of braking, a circular defense for the docking of boats of maintenance and security, and a mast that sustains a light of position. Preferably strobe.

This main buoy is the one that moves by impulse of the waves and currents and this translational impulse when being attached by its lower part by means of a rotating shackle to a chain fixed to a set of fixed elements, makes the displacement it is transformed into an ascending movement, and said movement is transmitted by means of the chain mentioned to the rest of the Device.

The aforementioned chain includes a small buoyancy buoy near the anchor with the rotating shackle that helps the main one, passing the mentioned chain through chain aligners, formed by a sheave attached to the main body by two symmetrical supports and then passing through three sheaves

These three rollers, located in a triangular position (their axes) have some with a channel retainer, and will move the inner axes of the waterproof case.

After going through these three sheaves, the chain goes through another set of aligners of the same structure, and ends up joining by means of a rotating shackle to a tension buoy of smaller size than the main one and in which a hoop is appreciated of defense and below the shackle a thin horizontal plate that serves as a stop against the retainers.

In this way the chain of union between the two is always tense and therefore working, either up or down so that depending on whether it is an upward or downward movement and the existence or not of chain retainers in the sheaves attached to the watertight body, movement is being transmitted to the whole at all times.

Subsequently, in parallel to this set, several sets of generation buoy equipment can be established, consisting of a regular size buoy, provided with its rotating shackle and flat stopper base from which a chain descends passing through an aligner of chain equal to those described above, then passing through three sheaves, located in a triangular and symmetrical manner as those described above, then passing through another chain aligner similar to the previous ones and ending in a tension buoy that involves a defense ring , a rotating shackle on its bottom and a flat stopper base. This set thus described, and which can be extended to many more sets, works as follows:

The continuous movement created by the buoy of generation, by means of the axes and gears that will be described is the section of the watertight box, it is transmitted by means of two drive pinions and an inner flat chain to the axis that moves this set, of so that it is sinking the buoy I ^to generation gradually. When the buoy generation I ^to touch with aligners chain through the top plate, an electric clutch is triggered, releasing this set and then transmiendose movement buoy generation 2, until the stop plate of this it reaches the corresponding aligners, at which point this axis is free and the movement begins to be transmitted to the buoy of generation 3 ^a and so on.

When the axis of the buoy from I ^to generation is free, the buoy from I ^to generation begins to rise, since it has no brake, but does not rise in a violent way, since the form of tension acts as a shock absorber.

In this way the rise of the buoy is continuous and at regular speed. As the free axis of the aforementioned buoy when it is free, it clings the other integral axis with the previous one that was free in the previous stage, this transmits the movement, already circulating to a centrifugal variator that in turn transmits it to a generator, which it is who through this movement it transforms into electrical energy that it sends through a suitable cable to the outside

In this way the main buoy is always working, which is the one that is responsible for submerging the buoys of generation that with its controlled and continuous ascension generates a constant and continuous movement, which is transmitted to the corresponding alternator.

Once the last generation set is loaded, that is, the corresponding generation buoy is in its most sunken position, the cycle begins with the I ^a .

One could say, with the corresponding physical qualifications that it is a "almost continuous" movement device.

The repetition of this cycle continuously is what achieves a constant flow of energy.

B.- Set of axles and gears of transformation of the main movement into electrical energy.

We have already described in the previous section of the general system of movement of the axes that we expand in this section.

The set of shafts and gears is located in a waterproof case, which has a safety railing on its upper outer part, topped at its ends by a perimeter defense, made of rubber or rubber to avoid violent blows from the possible vessels that arrive at the Device.

This box has on its outside the sheaves described above, each corresponding to an axis with different characteristics that we will see.

The rollers with retainer and located outside, correspond to the inside of the box with shafts, which involve a retainer in its closest part to the sheave, then placing a bearing support, a drive pinion, which drags a chain which transmits the rotation to an axis and ends in a bearing support

By means of the chains, rotation is transmitted to the axles with the help of the drive sprockets.

Then there is a shaft without a sheave on the outside, which in addition to the retainer includes a drive pinion, which through the chain transmits the rotation to the drive pinion of the shaft and also has a bearing support, a clutch, a drive pinion along with another parallel, this pinion by means of the tensioned chain, is related to another drive pinion that moves the other axes. From this drive pinion is an electronic clutch, the drive shaft, the drive itself, and the generator

The main axis of the main buoy also has:

A bearing with bearings, a closing coil, .- a clutch, a bearing with bearings, a drive pinion, a transmission chain, which connects the drive pinion with the drive pinion.- a drive pinion that moves a axis an axis that moves an alternator, an alternator that generates electrical energy that is transmitted by, a cable, that feeds a battery, .- auxiliary battery of the Device.

C .- Set of deposits and fixing weights at a certain depth of the entire device.

This set has as its main mission the positioning of the Device at the desired depth.

It is necessary to take into account that the working position of the Device is the sunken position at the bottom of the sea so that only the main buoy (a) that generates the movement protrudes. The rest remains sunk, resting on the seabed where it is supported by the stabilizer element, hydraulic element from which a shaft or leg of hydraulic movement, finished at the bottom by a support base.

But it is also necessary to keep in mind that the Device may also need to be moved at the time or simply for maintenance and repair.

Regardless of whether it is almost always possible to carry out maintenance work by means of submarine workers, in other cases, especially when it comes to work inside the waterproof case, it is necessary that such work be carried out on the surface.

For this, the Device has a counterweight, in the lower part of it, constituted by a rectangular rectangular parallepiped formed by high density metal elements or by concrete loaded with heavy particles.

Above this counterweight is a flood tank, equipped with an air inlet solenoid valve and a water inlet / outlet solenoid valve.

The flood tank is full of water when the device is to be fixed at the bottom of the sea. When you want the Device to surface, compressed air is introduced through the solenoid valve and the solenoid valve is opened, so that as the water tank is emptied, it rises to the surface. The introduction of compressed air into the tank is carried out by means of a tube attached to a buoy (g) that has a safety ring and an upper intake of compressed air. When the compressed air needs to be introduced into the buoy, a pressure hose is plugged into the valve

This ascent is carried out gradually and not violently due not only to the controlled compressed air intake, but also to the existence of the tension set (D), particularized in the buoy (h).

So that there is no displacement of the assembly, the chain can be used, conveniently anchored to the bottom by means of a dead person.

Above the flood tank is the waterproof case and above it is anchored to it a safety railing, finished by perimeter fenders, consisting of rubber or rubber elements that will serve as defenses for vessels that dock at their sides.

D .- Tension and tension maintenance set of the Device at the appropriate depth.

This set consists of a voltage buoy (h), which includes an upper air inlet valve and another air outlet valve.

This buoy is attached to the chain or end by means of a rotating shackle to which a free sheave is anchored. This chain / end is at one end anchored to a lower free sheave, subject to a buried dead, by means of a ring, while the lower sheave is subject to the dead by means of the ring.

The other end of the chain / end is attached to the outside of the waterproof case by conventional means (ring, knot etc.,).

This simple set allows to keep the device perfectly stable at the bottom of the sea, with the help of the buoy (h), which depending on the amount and compressed air inside it will create a different tension, but that said tension will always be to keep it in its correct position.

If the buoy (h) is partially emptied of air, and therefore exerts less tension pressure downwards, the assembly could move upwards with the help of its buoyancy aided by the reservoir filled with compressed air.

E .- Safety set and output of the main power cable.

The security set consists of a dead man, anchored at the bottom of the sea, which involves a ring that holds a chain, attached to the waterproof case by means of a ring.

The length of this chain will be enough for the assembly to emerge to the surface, but once it is in this position it cannot move. Based on this chain, the cable that transmits the electrical energy of the device to the ground is moved.

PREFERRED EMBODIMENT OF THE INVENTION.

So one or more devices placed along the coast can mean a constant and important generation of electrical energy from an inexhaustible and very cheap wave energy

The device for transforming wave energy into electrical energy that the invention advocates is constituted by the following main assemblies: A.- Main movement generation buoys set.

C- Set of tanks and fixing weights at a certain depth of the entire device.

D.- Tension and tension maintenance set of the Device at the appropriate depth.

E.- Safety set and output of the main power cable.

And each of these sets consists of the following main elements:

A.- Set of buoys generating the main movement:

It is constituted by:

Main movement buoy (a), consisting of a large floating buoy and in which that distinguish braking fins (3), a circular defense (4) for docking maintenance and safety vessels, and a mast (5) that supports a position light (6), preferably strobe.

This main buoy (a) is the one that moves by impulse of the waves and currents and this translational impulse when being attached by its lower part by means of a rotating shackle (7) to a chain (9) fixed to a set of fixed elements, causes the displacement to be transformed into upward-downward movement, and said movement is transmitted by means of the chain (9) mentioned to the rest of the Device.

The aforementioned chain (9) includes a small buoyancy buoy (8) near the anchor with the rotating shackle (7) that helps the main one, passing the mentioned chain (9) through chain aligners (36), formed by a sheave (38) attached to the main body (36) by two symmetrical supports (37) and then through three sheaves.

These three rollers, (39), (40) and (41) located in a triangular position (their axes).

The rollers (39) and (40) have a retaining channel, and will move the shafts (53) and (59) inside the waterproof case.

The sheave (41) has no retainers and is considered as insane turning in both directions, moving the shaft (65).

After passing through these three rollers (39), (40), and (41), the chain (9) goes through another set of chain aligners (36) of the same structure as the previous ones, and ends up joining by means of a rotating shackle (11) to a tension buoy (b) of smaller size than the main one and in which a circular defense ring (10) and below the rotating shackle (11) a thin horizontal plate ( 12) which serves as a stop against the retainers (36). In this way the chain (9) of union between both buoys, is always tense and therefore working, either up or down so that depending on whether it is an upward or downward movement and the existence or not of chain retainers in the sheaves attached to the watertight body, movement is being transmitted to the whole at all times.

Next and in parallel of this set of several sets of generation buoy equipment can be established.

In this case we will consider a simple field of a set of two buoys.

This set is made up of buoys (c) and (e), of regular size, provided with two rotating shackles (14) and (21) and flat bases (15) and (22) of stop which give rise to both chains (16) and (23) that go through two chain aligners (36) equal to those described above.

Then the chain (16) passes through the sheaves (42), (43) and (44).

The three sheaves, are located in a triangular and symmetrical manner as described above, then passing through another chain aligner (36) similar to the previous ones and ending in a tension buoy (d) that involves a circular ring (17) of defense, a rotating shackle (18) in its lower part and a flat base (19). The rollers (43) and (44) are retaining, and move the shafts (106) and (110), but not the flat channel (42), which moves the shaft (103).

The continuous movement created by the buoy of generation (a), by means of the axes and gears that will be described is the section of the watertight box, is transmitted by means of two drive sprockets and an inner flat chain to the axis that moves this together, so that the buoy I ^a of generation (c) gradually sinks. When the generation buoy I ^a (c) touches the sensors (142) by means of the stop plate (15), an electric clutch (75) is released, releasing this assembly and then transmitting the movement to the generation buoy 2 ^a , until the stop plate (22) of this activates the corresponding sensors (143), at which time this axis is free and the movement begins to be transmitted to the generation buoy 3 ^a and so on.

When the axis of the buoy from I ^to generation is free, the buoy from I ^to generation begins to rise, since it has no brake, but does not rise in a violent way, since the tension buoy (d) acts as a shock absorber.

In this way the rise of the buoy is continuous and at regular speed.

With the passage of the chain (16) through the pulleys

(43) and (44) since the retention axis (43) is free and when it is free, the other axis (68) is joined in solidarity with the previous one which in the previous stage was in the opposite direction and this transmits the movement, already circulating to a drive pinion (95) which by means of the chain (96) and the drive pinion (97) attached to the shaft (99) transmits the turning power to the maintenance alternator (98), which by cable medium (100), charge the work battery (lθl)

In this way the main buoy (a) is always working, which is the one that is responsible for submerging the buoys of generation (c) and (e) that with their controlled and continuous ascension generate a constant and continuous movement, which is transmitted to the variator (124) that in turn does it to the generator (125), where the electrical energy that will be sent abroad by means of the cable (81) is generated, a process that we will see later.

Once the last generation set is loaded, that is, the corresponding generation buoy (e) is in its most sunken position, the cycle begins with the I ^a (c).

The set of shafts and gears is located in a waterproof case (150), which has a safety rail in its upper outer part (34), finished off at its ends by a perimeter defense (35), of rubber or rubber to avoid the violent blows of the possible vessels that arrive at the Device.

This box has on its outside the sheaves described above (47), (46), (45), (44),

(43). (42), (41), (40) and (39), each corresponding to an axis with different characteristics that we will see

The sheave (47) with retainer and located outside, corresponds inside the box (150) with the shaft (134), which comprises a retainer (133) in its part closest to the sheave (47), placing a bearing support (135), a drive pinion (136), which drives a chain (138) that transmits the rotation to the shaft (115) and ends in a bearing support (137).

The sheave (46) with retainer and located on the outside, corresponds inside the box (150) with the shaft (130) which contains inside a retainer (129) and in its innermost part with a pinion of drag (131) and end in a bearing support (132).

By means of the chain (172) it transmits rotation to the shaft (115) with the help of the drive pinion (117). The smooth groove (45), located outside, corresponds to the inside of the box (150) with the shaft (127), which includes a retainer (126) and a bearing support (128).

Then the shaft (115) without a sheave is located on the outside, which in addition to the retainer (114) includes an arrate pinion (116), which by means of the chain (111) transmits the rotation to the drive pinion (107) of the shaft (106) and which also has a bearing support (118), a clutch (121), a drive pinion (119.a) together with another (119. b). The pinion (119. b) by means of the chain (138) tensioned by the tensioner (139), is related to the drive pinion (136) of the shaft (134).

From the drive pinion (119. b) there is an electronic clutch (122), the shaft 8123) of the drive (124), the drive (124) itself, and the generator (125).

The sheave (44) with retainer and located outside corresponds to the inside of the box

(150) with the shaft (110) that contains a retainer (109) on the inside, with a drive pinion

(112) and a bearing support (113) at the end.

The sheave (43) with retainer and located on the outside, corresponds to the inside of the box (150) with the shaft (106) that contains a retainer (105), a drive pinion (107) ) and supported in its final part by a bearing support (108). The chain (111) joins the drive pinion (107) with the drive pinion (116) The sheave (42) of smooth throat and located on the outside, corresponds to the inside of the box (150) with the shaft (103) and a bearing support (104) at the end

Then the shaft (68) without a sheave is located outside, which in addition to the retainer (67) located against the wall of the box (150), carries a drive pinion (69), followed by another drive pinion (70 ), followed by:

A bearing with bearings (71), .- a closing coil (77), a clutch (78), .- a bearing with bearings (79), .- a drive pinion (95),

.- a transmission chain (96), which connects the drive pinion (95) with the drive pinion (97), .- a drive pinion (97) that moves an axis (99), an axis (99) that moves an alternator (98), .- an alternator (98) that generates electrical energy that is transmitted by, .- cable (100), that powers a battery (101), .- battery (101) auxiliary to the Device.

The smooth groove (41), located outside, corresponds to the inside of the box (150) with the shaft (65), which includes a retainer next to the wall of the box and is supported by a support with bearings (66)

The sheave (40) with retainers, located outside, corresponds to the inside of the box (150), with the shaft (59), which comprises a retainer (58) next to the wall of the box, then the drive pinion (60) sharing the chain (144) with the drive pinion (69) ), and that ends in a bearing support (61).

The sheave (39) with retainers, located on the outside, corresponds inside the box (150), with the shaft (53), which comprises a retainer (52) next to the wall of the box, being next the closing coil (54), which acts on the clutch (55), then the drive pinion (56), which by means of the chain (63) properly tensioned by the tensioner (62) moves the drive pinion (70); and ending the shaft (53) in a bearing support (57)

It is necessary to take into account that the working position of the Device is the sunken position at the bottom of the sea so that only the main buoy (a) that generates the movement protrudes. The rest remains sunk, resting on the seabed where it is supported by means of the stabilizer element (90), hydraulic element from which a shaft (91) or hydraulic movement leg, finished at the bottom by a support base (92). ). But it is also necessary to keep in mind that the Device may also need to be moved at the time or simply for maintenance and repair.

Regardless of whether it is almost always possible to carry out maintenance work by means of submarine workers, in other cases, especially when it comes to work inside the waterproof case (150), it is necessary that such work be carried out on the surface.

For this, the Device has a counterweight (89), in the lower part thereof, constituted by a rectangular rectangular parallepiped formed by high density metal elements or concrete loaded with heavy particles.

Above this counterweight (89) is a flood tank (86), equipped with an air inlet solenoid valve (87) and a water inlet / outlet solenoid valve (88).

The flood tank (86) is full of water when the device is to be fixed at the bottom of the sea. When you want the Device to surface, compressed air is introduced through the solenoid valve (87) and the solenoid valve (88) is opened, so that as the water tank is emptied, it rises to the surface.

The introduction of compressed air into the tank

(86) is performed by means of a tube (228) attached to a buoy (g) by means of a rotating shackle (227) and which has a safety ring (224) and a superior compressed air intake (225). When the compressed air needs to be introduced into the buoy, a pressure hose is plugged into the valve (225)

So that there is no displacement of the assembly, the help of the chain (83), conveniently anchored to the bottom by means of the dead (85), is available.

Above the flood tank (150) is the waterproof case (150) and above it is anchored to it a safety railing (34), finished by perimeter fenders (35), consisting of rubber or rubber elements that they will serve as defenses for vessels that dock at their sides.

This assembly consists of a voltage buoy (h), which includes an upper air inlet valve (31) and another air outlet valve (31 ^' ).

This buoy is attached to the chain or rope (30) by means of a rotating shackle (326) to which a free sheave (27) is anchored. This chain / end (30), is at one end anchored to a lower free sheave (28), attached to a dead (33) buried, by means of a ring (29), while the lower sheave (28) is is subject to the dead by means of the ring (32).

The other end of the chain / end (30) is attached to the outside of the waterproof case (150) by conventional means (ring, knot etc.,).

If the buoy (h) is partially emptied of air, and therefore exerts less tension pressure downwards, the assembly could move upwards with the help of its buoyancy aided by the reservoir (86) filled with compressed air.

E .- Safety set and output of the main power cable.

The safety assembly consists of a dead person (85), anchored at the bottom of the sea, which involves a ring (84) that holds a chain (83), attached to the waterproof case (150) by means of a ring (82 ). The length of this chain will be enough for the assembly to emerge to the surface, but once it is in this position it cannot move.

Based on this chain (83), the cable (81) that transmits the electrical energy of the device to the earth is moved.

Describing sufficiently the nature of the invention, as well as the manner in which it is put into practice, it should be noted that the provisions indicated above and represented in the attached drawings are subject to modifications in detail as long as they do not alter its fundamental principles, established in the paragraphs. above and summarized in the following claims.
