Description

MOTOR FORCE GENERATOR DEVICE

The present invention relates to a driving force generating device, and in particular to a driving force generator that uses energy

kinetic and pressure - exerted on it by a

fluid, being especially indicated for the conversion of the energy contained in the seas and oceans.

BACKGROUND OF THE INVENTION

The objective of traditional driving force generating devices is the use of dynamic energy that concentrates air, water and others

fluids for the generation of mechanical or electromotive forces. The fact that these devices are capable of producing depends on the volume, mass and speed of the fluid they work with, so that the

energy that they can convert grows or decreases directly with their size, while doing so

much more than proportional to the intensity of the exploited phenomenon.

The objectives of improving energy use face multiple difficulties among the

that important conditions of a dynamic, mechanical and electrical nature are counted. In the specific area of the use of energy contained in transport elements in seas and oceans such as sea waves or tides, the following is added: difficulty adapting to

Extreme variations that these can present. Mechanical and mobile elements must be designed to

eventually resist great efforts and consequently are valid only for certain geographical areas and configurations, thus moving away the possible application of

these devices in a generalized scope.

With the VQ device of the present invention, the aforementioned drawbacks are resolved, presenting other advantages that will be described.

In the classification of devices

5 oriented to the use of the energy contained in seas and oceans, was divided between two large families, taking into account the different origins of energy. Tidal energy, which is produced by the tides, can be easily harnessed by channeling water through

10 of turbines, taking advantage of the entry of water when the tide is at its highest level and dropping it, or taking advantage of the flows or currents that occur due to the interaction of gravitational attractions and coastal profiles. The second type refers to the use of

wave energy, which is what the waves accumulate and through them is transported by the oceans to the coasts, where their dissipation occurs. While there are hundreds of inventions concerning this second type of

20 devices, although very few have become the object of commercial exploitation, practically all of them are likely to be grouped into three categories: the Appliances anchored to the bottom and with a buoy attached to it with a cable. The buoy movement is

25 used to move a generator. Another variant would be to have the machinery on land and the buoys stuck in a well connected to the sea.

2. Floating apparatus of articulated parts that

they get energy from relative motion between their parts. 30 They are commonly known as "sea snakes."

3. Apparatus consisting of a well or container with the hermetic upper part and the lower one connected to the sea. The air, water or hydraulic fluid q ': it is pressed by the waves moves a turbine which is what

35 generates electricity.

mobile that can move inside an accommodation; Y

at least one actuator that causes the

displacement of said = mobile slow of said generator

linear inside said housing, whose movement is triggered by alterations in the gravitational attraction of the earth, by pressure differences, and / or by induced kinetic forces.

Additional optional features are

-

said linear generator is located outside the sealed body;

-

said mobile element is a magnet;

-

said housing comprises at least one

coil arranged around: r thereof;

It should be noted that the movement of said actuator mechanism and that of the mobile part of the generator can be attenuated either: or by direct physical action as electro-mechanically, constituting a mass-spring system in which the mass imbalance contributes to the oscillation of the generating system, and at the same time the whole becomes more vulnerable to sudden movements and unexpected forces.

Additionally, the apparatus can house control elements or conversion of the generated current such as diodes, capacitors or accumulators, as well as

elements

consumers connected to the circuit such horn

lights,

resistances, emitters or receivers from radio,

electro-magnets

or servomotors.

It allows various positions, on the surface, at indicated working depths, or under these, being able to avoid the effects of extreme adverse conditions.

it allows the storage of energy in the device itself or the evacuation of it from the device in the best way indicated.

In addition, the present invention does not present some of the drawbacks of existing designs:

-

avoids the need for sophisticated roots or foundations at the bottom: marine.

avoids the presence of trajectories or mobile joints sensitive or exposed to the outside; dispenses with baffles and other accessories to direct or concentrate - the flow.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The device of the present invention, according to the first embodiment illustrated in Figure 1, comprises a spherical shaped body 1, whose upper volume is occupied by low density inorganic foam in order to ensure a positive buoyancy, effectively neutralizing its weight whether it floats in the sea or if it is submerged.

Said watertight body 1 contains an electric generator of linear type 2 arranged in a horizontal position, comprising a mobile element or piston 2a that travels inside a housing 2b. This mobile element, according to this first embodiment, is formed by one or more permanent magnets. The fixed part, or stator, of the generator contains one or more coils (not shown) wrapped around said housing 2b through which the movable element 2a slides. It should be noted that said coil (s) has not been represented for reasons of simplicity "

At both ends of this housing 2b are

there are stops or seals 3 that delimit the movement of the piston 2a. These stops 3 are preferably directly subjected to the effect of one or more actuators 4, which are each constituted, in the case of this first embodiment, by an arm coupled to an elastic membrane 5 some1: gone from its external face to the external pressure and its internal face to that of the pressurized chamber of the sealed body l.

The passage of the wave through the device produces several effects. An effect is a change of seat that directly alters the gravitational attraction on the mobile element 2a of the piston and causes the movement of the

same. This effect is also accompanied by a compression / depression of the membranes 5 of the pressurized chamber, produced both by the direct incidence of the mass of moving water and by the changes in the height of the water column that periodically covers the device The present invention.

By means of the lever mechanism of the actuator arm 4, it is possible to transmit the pulsating effects to the stops 3 delimiters of the movement of the piston 2a, which in this way is compelled again and again to modify its position with respect to the position: movement, movement that generates electricity.

In the second preferred embodiment of FIG. 2, a variation is presented that allows a different use of the inertial impulses that is especially special.

, interest in high power settings. It should be noted that in this second embodiment the same numerical references are used as in the first embodiment to designate equivalent elements,

adding a number 1 in front. Thus, the sealed body defined in the first embodiment with the numerical reference 1, is indicated in the second embodiment with the numerical reference 11.

In this second embodiment, the tight body

11 is primarily designed as a buoyancy reserve that will be subject to structural requirements. The incorporation of a joint or lever mechanism 16 pE! Governs the location of the generator

linear 12 outside the watertight body 11. In this way, a response is achieved in direct relation to inertial impulses in which the pressure variations are also used, since they can be redirected to seat changes by means of the mentioned joint. In this case,

the stops 13 can be driven by the pressure that originates in the displacement of one or more actuators 14, which in the embodiment shown in Figure 2 are hydraulic pistons.

Similar to the previous case, an elastic membrane 15 is also used to seal the floating body, although here its usefulness is to a greater extent to provide a sealing gasket, rather than to react to variations in external prision.

The mobile element 12a of this embodiment is also a magnet that travels inside a housing 12b, which may be filled with coolant. The displacement of the mobile element l2a is limited by a pair of stops 13, placed at the two ends of said housing l2b.

Also in this case, one or more coils are arranged around the mobile element l2a, which are not represented for simplicity.

In the third preferred embodiment of Figure 3, the basic approach is the autonomous power of a low power equipment, illustrated here as a

waterproof body 21 in the form of a castor or buoy with light.

Also in this case, it should be noted that in this third embodiment the same references are used

numerical than in the first embodiment to designate 5 equivalent elements, adding a number 2 in front. From

in this way, the sealed body defined in the first embodiment with the numerical reference 1, is indicated in the second embodiment with the numerical reference 21.

Being relatively low energy the

10 which is to be obtained, a simpler form of a linearly arranged linear generator 22 is used, which is sufficient to be driven from one of the ends, while at the opposite end a rubber stop 23 is provided which dampens and contributes to the change of travel. The utility of the end has been proven

operated have a magnetic actuator 24 of the same sign as that of the magnet that! it forms the mobile element 22a of the linear generator 22 that travels inside the housing 22b. The elastic membrane 25 has the form 20 of a dome or bell and its sealing is done by means of a

adjustable closure 26. The adjustment contributes to the element

Mobile 22a of generator 2.2 is by default in the central area of the coil. The inertial and pressure impulses affect the masses separately causing

25 imbalance Also in this case, around the mobile element 22a is arranged. one or more coils, which is not

represent for reasons of simplicity. It should be noted that, in any case, the orientation of the device is not relevant, while the

Linear generator mobility is arranged so that it is affected by the passage of the wave.

If on the third: the embodiment of Figure 3 explains how to drive the effects of pressure and gravity to the same drive, in the fourth embodiment

the electromagnetism to promote the movement of the piston 32a of the generator, depending on its orientation. Figure 4 shows how to take advantage of the effects separately even if they act in orientation planes

5 different, on the one hand by displacing the mobile element 32a, which is a magnet, inside the housing 32b by reaction to pressure impulses, while on the other it acts in response to inertial impulses.

Also in this case: one or more coils, which are not represented for simplicity reasons, are arranged around the mobile element 10a.

Although reference has been made to a

series of concrete embodiments of the invention, is

evident to a person skilled in the art that the device

15 described is subject to numerous variations and modifications, and that all the mentioned details can be replaced by other technically equivalent ones, without departing from the scope of protection defined by the attached claims.
