Abstract

The invention relates to a converter for converting the energy of a fluid that is still or in motion, said converter comprising a shaft having aerodynamic bodies arranged in such a way that, when moving, the lift force produced by said bodies acts like torque applied to the shaft. As it rotates, the shaft transfers the movement thereof to the aerodynamic bodies such that said bodies produce lift and torque, and the cycle is repeated in this manner. For example, the Eppler 479 profile produces up to 100 times more lift than drag when moving. According to the invention, the lift force of 100 is used to overcome 1 unit of resistance force of the body and the remaining 99 units are used to maintain movement and to overcome mechanical resistance (+/- 30%), the remaining force producing electricity or work.

Description

FLUID POWER TRANSFORMER

DESCRIPTION TECHNICAL FIELD OF THE INVENTION.

The present invention relates to various apparatus, methods and arrangements that transform the energy of free or stagnant fluids into work or electricity, by the novel use of the lift force produced by aerodynamic bodies when moving inside a fluid without need to use any fuel for its operation, and to be applied in any human activity.

BACKGROUND Since the dawn of civilization, man has transformed the energy of accelerated fluids to his advantage through various applications, among which are: Hydraulic Turbines and Wheels, Windmills, Wind Generators of various types, including those based on the "Magnus Effect" etc. However, it can be stated that all current mechanisms have at least one or more of the following defects:

They do not work on demand but are subject to weather conditions.

They need the fluid to be in motion.

Hydroelectric farms require large investments in infrastructure and on the other hand they incur high environmental and social costs in the construction of dams that adversely affect entire communities and Ecosystems. It is necessary to implement large distribution networks since the consumption centers are generally far from the energy production centers.

Wind farms require large devices, are inefficient due to the inconstancy of the wind, require systems to store energy, produce visual pollution, are a threat to birds and are considerable distances from consumption centers.

Geo-Thermal farms can only be used where there are adequate conditions and these do not abound.

Solar and photovoltaic farms require large areas of land, do not work at night and are expensive today.

All require large initial capital investments.

The other fossil fuel-based energy transformation alternatives are also expensive, polluting or contribute to global warming. Atomic energy is dangerous and polluting and there is currently no renewable, cheap, reliable and non-contaminating energy source.

All of the aforementioned affects poverty, wars and lack of opportunity for a large sector of humanity that does not have the resources to pay more and more expensive and polluting energy.

The object of the invention is to provide methods and apparatus for producing electricity or useful work in industry or the home without the need for substantial investments, that does not contaminate, that is renewable, that works in any atmospheric condition without using any type of fuel additional more than the internal energy of the fluids even if they are at rest and without the disadvantages of existing devices so far.

The present invention is based on the Support Force that occurs when a body moves within a fluid, in this condition instantly appear forces that try to delay the movement and also forces that try to deflect the object of its trajectory, the the first one is called Advance Resistance and the second one is called Sustainability and Normally it acts at 90 ° from the direction of body movement, its intensity depends on several factors such as the density of the fluid, the square of the velocity, the dimension of the body, its shape, its position and others.

The Aerodynamic Efficiency (EA) of a body consists in producing the maximum of Sustainability with the minimum of Advance Resistance, this is an area that requires a lot of understanding since its manifestations may seem illogical at first sight, for example the alar profile shown in Fig. 1, has the same resistance to advancement as a wire having a diameter 10 times smaller, Source: Fluid dynamics of drag part IV, Massachusetts Institute of Technology. On the other hand we have a modern aerodynamic profile, the Eppler 474 depicted in Fig. 2 in cross-section, which has an EA greater than 100. Source: Airfoil Investigation Datábase. This means that this aerodynamic profile when moving within a fluid produces at the same time, 100 units of lifting force against a 1 unit of advance resistance. To quantitatively illustrate the EA, let us take as an example the plane "Global Flyer" that in February 2006 went around the world without refueling at 76:45 Hrs.

This aircraft weighed an average of 5851 kg between full and empty and had an EA of 37/1, it follows that the Global Flyer needed only 1 Kgf of thrust to produce 37 Kgf of lift, therefore to keep in straight flight and leveled an average weight of 5,851 Kg, it used only 158Kgf of thrust.

In the condition of cruise flight (Straight and level) the result of the forces acting on the aircraft is 0, the lift force of 5,851 Kgf, is compensated with 5,851 Kgf of gravity and 158 Kgf of engine thrust, are compensated by 158 Kgf of the

Drag. This condition is represented in Fig. 3.

Now let's think of a mental experiment in which the Global Flyer loses 2,000 kg of weight (because suddenly the fuel leaked, say) and we maintain the same 158 kg of engine thrust that produce 5,851 kg of lift. Having less weight to sustain, the lift force is no longer balanced, it is greater than the gravity force, so the plane will rise with an acceleration of 1.51 M / s2.

The net result of this experiment is that 3,851 Kg (5000-2000 = 3,851) can be moved up, using only 158 Kgf of energy and with an acceleration of 1.51 M / s, without the help of any additional mechanism.

This does not mean that the plane had produced energy from nothing, this result is possible because we get the contribution of other energies that are there, surrounding us in the atmosphere and entering into play due to the speed with which the wings of the plane interact with the molecules of the air, facilitating that the energies contained in it manifest and contribute to the lift, energies such as the force of the atmospheric pressure, the intermolecular force of the air, the force of adhesion and the drag force of it, the force of gravity etc. which cause a volume of 5,851 kg of air to be diverted down to 9.8 M / s and the plane held up. (Source: Understanding Flight 2nd edition by David Anderson and Scott Eberhardt, McGraw-Hill, 2009).

Reflecting on these properties, I came to the conclusion that an initial force could be used to accelerate an aerodynamic body at a certain speed to produce enough lift and that instead of using the force difference (Lift-Resistance) so large to support an aircraft in the air, it would be much more useful to "deflect" said lift force and use a part of it to maintain speed and therefore lift and excess force, use it in a way that produces another usable movement in another manifestation of energy .

For example, of the 100 lift units produced by the Eppler 479 profile against 1 feed resistance unit, take a lift force unit to nullify the feed resistance unit and the remaining 99 force units, use them to maintain speed and produce work or electricity and repeat the cycle as necessary without using additional fuels or energy. The implementation of this invention in the form detailed below, solves all the problems mentioned at the beginning of the background and has the following virtues:

Work on demand in any weather state.

Work anywhere in the world where there is or can take a fluid.

They are not affected by winds, rains, hurricanes or the sun shines or is cloudy or at night.

Simple, compact and economical construction. The structure can be PTR, Tube

Galvanized or Plastic and the rotors or primary devices that produce lift. PVC

In its simplest configuration it consists of a few pieces, without demeriting the power delivered.

Low initial investment, very easy to build and maintain.

The cost of energy production is practically zero.

It does not need distribution networks because, due to its low costs, it can be built to supply from a small house to a city or housing blocks, factories or shops, with strategies that avoid the construction of expensive, complex and vulnerable distribution networks such as the current ones. .

You do not need devices to store the energy produced.

It has the ability to efficiently extract energy from confined or stagnant or free fluids. It is ecological, does not leave any type of waste.

Therefore, it is intended to protect said Devices, Provisions and Methods of extraction and conversion of energy from fluids, by means of the present application, since it is an innovation that grants the possibility of harnessing the energy of fluids at rest as never before. before it has been done, turning it into electricity or work.

DETAILED DESCRIPTION OF THE INVENTION

PREFERRED CONFIGURATIONS

The invention consists of various apparatus and arrangements that transform the energy of the fluids through the novel use of the lift force so that it produces acceleration in the body itself, without using any fuel or other materials for its operation and using the excess support to produce work or electricity. FIRST MODE

An energy transformer of a fluid, characterized by having a central vertical axis (1) that is fixed to a larger element for stability (2), this axis (1) is characterized by being fixed and being the support of the entire apparatus, This axis (1) is linked by means of bearings to another external axis (3) that surrounds the axis (1) and is characterized by being able to turn freely. The external axis (3) is characterized by having linked a horizontal platform (4) of circular preference that rotates together with said external axis (3), said platform is characterized by having linked to the floor and the external central axis (3), a cylindrical container (5) preferably, filled with a liquid fluid, preferably water (6) that rotates together with the external central axis (3) and with the platform. Said platform is characterized by having fixed one or more structures in the form of vertical posts (7) distributed on the periphery of the platform, linked to each other by beams (8) in its highest part to give them rigidity. Said posts are characterized by comprising a horizontal crankshaft (9) that rotates around its axis and that carries a pulley (10) or similar that rotates freely and another wheel (11) linked to the crankshaft axis, said wheel (11) is characterized by being able to slide along the crankshaft when it is driven by a servo motor (12) or by a mechanical device that couples it to the pulley (10) that rotates freely. In this way the circular movement of the pulley (10) that rotates freely now drags the crankshaft (9) in its turn. Said crankshaft is also characterized by having one or several rods (13 and 14) connected as pistons that cross a beam (15) containing guides to guide the vertical movement derived from the crankshaft rotation. Said rods carry aerodynamic bodies (16 and 17) at their end furthest from the crankshaft mounted in a manner aligned with the radius of the circular platform itself that pass through the fluid from top to bottom and vice versa, mounted to produce lift with horizontally deflected direction to 90 ⁰ of the platform radius.

Since said aerodynamic bodies are arranged Radially opposite to each other, the bearing forces they produce are opposite and form a cupla see Fig. Fig. 14 and produce a torque, These aerodynamic bodies are further characterized by having their outer ends designed to sliding by means of bearings on a vertical rail (18) linked to the wall of the cylindrical container and its inner end to slide on another track attached to the outer vertical central axis (27), so that the cupla has the ability to produce a torque and keep the platform spinning.

In addition, the platform (4) is characterized by having a set of mechanisms under the floor that complement and interact with those already mentioned: It has a set of gears (19) and pinion (20) where the gear is fixed to the central axis (1), which in turn is fixed to the larger element by a structure (2) as mentioned in the beginning. Said pinion (20) is radially arranged and rotates in conjunction with the platform (4) with its inner end coupled to the fixed gear (19) such that when turning around the gear (19), it forces it to rotate on its axis longitudinal. Said longitudinal axis is characterized in that at its outer end there is linked a gear (21), pulley or the like, linked in turn by means of a belt, chain or similar (22), with the wheel (10) that rotates freely in the crankshaft (9) which remains static as long as the wheel (1 1) is not attached.

The movement is started manually by turning the platform like a carousel or by means of a generating motorbike (23) activated by a power source (24), said generating motorbike is coupled to the outer central axis (3) by means of a gearbox (25 ) or similar, until the platform acquires a predetermined angular velocity, and the liquid fluid is turning as solid, at that time the accelerator is manually stopped or the motorbike is disconnected and by means of the mechanism (12) the crankshaft wheel (1 1) with the wheel rotating freely (10). In this condition the crankshaft begins to rotate and moves the aerodynamic devices (16 and 17) within the fluid, producing lift in the manner described above.

Since the lifting force is several times greater than the effort to move the aerodynamic bodies within the fluid and since the platform is already rotating and no further acceleration is required, the only additional force to overcome will be the frictional force of the mechanisms involved in the operation and all the surplus is used to generate work or electricity by means of the generating motorbike (23) to recharge the power source (24) or be used in any human activity through the distributor (26).

If more lifting force is required, it is sufficient to accelerate the angular velocity of the platform to a higher value so that the aerodynamic bodies increase their speed with respect to the fluid, remembering that the lifting force is increased as a function of the square of the speed and that the aerodynamic resistances to the advance, are a tiny part of the total of the force generated while the mechanical friction forces do not increase

expose such as the lifting force.

To stop the rotation, simply undo the wheel 1 1 of the pulley 10, this will cause the aerodynamic bodies to stop, without movement there will be no lift or torque.

Figure 14 shows a plan view of the apparatus with indication of the lift force vectors represented in the way they act. SECOND MODE

The Energy Transformer of a fluid characterized by certain aerodynamic bodies (35) aligns with the same direction of the rotation axis (31) and moves radially outward and towards the center within a cylindrical or circular crown container preferably (34) by means of a rail (33), in this case the apparatus consists of a central friction gear or wheel (32) and a series of planetary gears (36) linked to the rotating platform that when rotating around the gear or central friction wheel (37) prints to the planetary gears (36) a rotational movement that is transmitted reciprocatingly to rods (38) that at their end furthest from the solar gear (32) carry aerodynamic bodies that produce torque support to rotate the platform. Once a predetermined speed has been set, a generator is coupled to the central axis to produce electricity or work. To stop the device, simply disconnect the solar gear from the planetariums

THIRD MODE

An energy transformer of a fluid characterized by comprising an axis (42) with aerodynamic bodies arranged in such a way that when moving the lifting force they produce acts as a torque applied to the same axis. Said axis transfers its movement to the aerodynamic bodies so as to produce lift and torque and thus the cycle is repeated, it also comprises a structure (41) that is fixed within a body of stagnant or running water so that it remains firm since said structure supports the entire apparatus. Said apparatus comprises a vertical axis (42) which in turn comprises an element (43) that slides along said axis and can also rotate together with the axis. Said element has a plurality of aerodynamic bodies (44 and 45) linked and also has the necessary mechanisms (46) so that upon reaching the upper end, the configuration of the aerodynamic bodies (44 and 45) changes to produce negative lift of such that the element (43) initiates a movement to the other end so that when the mechanism ^' (46) reaches the other end, it acts in reverse and the element (43) now moves upwards and so on.

Said element (43) has a suitable device (47) connected to push and pull the device (48) that has connecting rods or rods (49) that cross the beam (50) and give it a rotational movement to the cranks (51). ) so that they rotate the shafts (52 and 53) in the same clockwise or counterclockwise direction (seen from said shafts) and they rotate the gears (54 and 55) that rotate the gear (56) together with the gear (57) linked to the shaft (42) on which the aerodynamic bodies (44 and 45) that produce lift are mounted repeating the cycle up and down. The gears (54 and 55) also move to the gear (56) that rotates the shaft (59) and this to a flywheel (60) for a more stable operation and the linked generator motor (61) or any machine tool to produce electricity or useful work.

The movement can be started manually or through the generating motorbike (61) assisted by a power source (62) until the device reaches a certain speed stops accelerating and is allowed to continue with its own energy to recharge the power source and generate work directly or produce electricity and distribute it through the element (63)

To stop the rotation of the aerodynamic bodies, a mechanical or aerodynamic brake (64) acting on the element (46) that carries the aerodynamic profiles and a hydrodynamic governor are used to regulate the speed of rotation of the shaft. HOW TO USE THE FLUID POWER TRANSFORMER.

Since the manufacture of the invention is relatively inexpensive, it can be used domestically to produce electricity for the home with an almost zero production cost since the devices do not consume other energy and only transform that of the fluid (Intermolecular, Gravity, Viscosity, Drag Etc.) said fluid can be as common and abundant as seawater or any other fluid, easy to replace. Various devices can be built for different social groups to make the production of electricity redundant. As well as build various devices to supply buildings, communities etc.

It can be applied to desalinate seawater or produce hydrogen at low cost for industrial uses, etc.

Having clean, renewable and inexhaustible energy has countless positive applications for society in the fields of Industry, Agriculture, Transport and in all areas of human activity.

21 .- METHODS FOR THE SUBSTANCE PRODUCED BY AN AERODYNAMIC BODY TO PRODUCE ACCELERATION IN THE OWN BODY AND METHOD TO TAKE ADVANTAGE OF THE SUBSTANCE OF SUBSTANCE TO PRODUCE USEFUL WORK IN ANY HUMAN ACTIVITY

FIRST METHOD

A first method is to link one or more aerodynamic bodies of high EA to an axis that has the possibility of rotating on itself. The aerodynamic bodies are arranged so that when they move the lifting force they produce, it acts as a torque applied to the same axis. Said turning axis transfers its movement to the aerodynamic bodies so as to produce lift and thus the cycle is repeated. One way of obtaining this is by arranging the aerodynamic bodies radially with respect to the axis and moving the aerodynamic bodies reciprocatingly in a parallel direction the longitudinal axis of the axis of rotation. These aerodynamic bodies must be oriented so that they produce lift at 90 ° of their trajectory and in a single direction as a Torque that rotates the axis. To obtain a great bearing force, a fluid of greater density than air must be used, for example water, confine the fluid and rotate it with the same angular velocity as the axis, the above will allow aerodynamic bodies, in relation to the fluid , they are only moving on the axis of the "Y" and can produce a lift at 90 ° with the minimum resistance to the advance and the highest possible torque.

Said main axis comprises the necessary mechanisms (pulleys, gears, pumps, Etc) to convert its rotation movement into reciprocating rectilinear movement to move the aerodynamic bodies and produce lift and thus the cycles are repeated.

Aerodynamic bodies with high EA ratios should be preferred; For example: Profile Mod. Eppler 479, or GOE 531 that have ratios 100 and 300 times or more than the resistance to the advance (Source Airfoil Investigation Datábase.) this is very important because this excess of force is the one used to overcome to the parasitic resistance by friction of bearings, gears, etc. and produce useful work in any human activity.

SECOND METHOD

A second method consists in introducing into a body of stagnant or running water, a rotating shaft that has one or more elements linked to different bodies.

Aerodynamics of high EA that can rotate as a propeller and produce positive lift in one part of the turn and negative lift in another part of the rotation, this will cause the element carrying the aerodynamic bodies to slide alternately towards one end and the other of the axis of rotation with a force proportional to the lifting force developed by the aerodynamic bodies.

The axis of rotation has the necessary elements (differential gears, rods, pumps Etc) to transform the reciprocating movement into force that rotates the axis itself and the aerodynamic bodies so that they continue to produce positive and negative lift and so the cycle is repeated.

22. Different types, layouts, quantities , and configurations of any method or system described herein can be developed without departing from the scope of the various configurations here ^"described. Major or minor components other arrangements, horizontal, vertical or inclined streamlined bodies or the axes that receive the torque, also fall within the scope of the present invention.
