Abstract

The present invention relates to a "pressure engine" applying "Archimedean thrust" or upthrust; the difference in pressures applied inside a liquid environment may be recovered as a source of motive power and of energy. To do this, use is made of two elements: firstly, a bearing structure such as a mast supporting floating bodies duly shaped into a spiral-like shape and submerged and, secondly, either a fulcrum which acts as a lever allowing the floating bodies to revolve on themselves or a guideline (rail) that also gives them the possibility of at the same time moving in an epicyclic path, and also of setting the bearing structure in motion. The present invention is an iterative imbalance hydromechanical device driven by the difference in pressures which permits the continuous rotational action. Use is thus made, in a closed circuit, of an energy that is non-polluting, non-fossil, completely renewable, and which in particular opens the way to numerous applications including those in the domestic field and environmental protection.

Description

Nouveau moteur à pression et ses applications New pressure engine and its applications
La présente invention concerne un « moteur à pression » qui permet, grâce au [1] positionnement contraint d'une structure composée de corps flottant(s) immergé(s) dans un milieu liquide (inerte ou non et éventuellement captif), d'utiliser comme source motrice la différence de pressions exercées sur les dits corps flottants à l'intérieur de ce liquide dès lors que ceux-ci sont soumis à au moins deux forces antagonistes : la force de la poussée d'Archimède et celle de la gravité.The present invention relates to a "pressure motor" which, thanks to the [1] constrained positioning of a structure composed of floating bodies (s) immersed (s) in a liquid medium (inert or not and possibly captive), of to use as a driving source the difference in pressures exerted on the said floating bodies inside this liquid as soon as they are subjected to at least two opposing forces: the force of Archimedes' thrust and that of gravity.
Plus précisément, ce « moteur à pression » est constitué par un dispositif de captage et de guidage des pressions grâce au positionnement contraint des dits corps flottants. Ceux-ci, sous l'action de la double poussée liée à leur immersion, sont, d'une part, soumis à une rotation à partir d'un point d'appui (effet de levier) et, d'autre part, entraînés le long d'une ligne de guidage (rail) assurant la mobilité de l'ensemble de la dite structure.More precisely, this "pressure motor" is constituted by a device for sensing and guiding pressures by virtue of the constrained positioning of said floating bodies. These, under the action of the double thrust related to their immersion, are, on the one hand, subjected to a rotation starting from a point of support (leverage effect) and, on the other hand, driven along a guide line (rail) ensuring the mobility of all of said structure.
Selon l'invention, cette force motrice est captée par des corps flottants, totalement ou partiellement immergés, qui présentent les caractéristiques suivantes, qui résident dans le fait qu'ils sont pivotants et, par exemple, de forme tubulaire et / ou à spires de façon à canaliser hydromécaniquement la différence entre les dites poussées et d'être ainsi entraînés dans un mouvement de rotation selon une caractéristique de l'invention.According to the invention, this driving force is captured by floating bodies, totally or partially immersed, which have the following characteristics, which reside in the fact that they are pivotable and, for example, of tubular shape and / or with turns of so as to hydromechanically channel the difference between said pushes and be thus driven in a rotational movement according to a feature of the invention.
Les dits corps flottants sont non seulement solidaires d'une structure porteuse (mât), mais chacun d'entre eux est en appui sur un point fixe ou bien sur une ligne de guidage (par exemple horizontale ou en pente, linéaire, courbe ou circulaire), le long de laquelle ils peuvent se déplacer.The said floating bodies are not only integral with a support structure (mast), but each of them bears on a fixed point or on a guide line (for example horizontal or sloping, linear, curved or circular ), along which they can move.
Selon l'invention, la transformation hydromécanique des forces antagonistes en un mouvement giratoire continu est obtenue de façon mécanique grâce à l'introduction d'un positionnement en déséquilibre itératif des dits corps flottants de façon qu'ils reconduisent à la fois leur rotation dans une trajectoire pouvant être par exemple épicycloïdale ainsi que la rotation centrale de la structure porteuse pivotante (mât). L'ensemble de ces mouvements circulaires permet ainsi la capture durable d'une partie de l'énergie dans le but de la transformer en une source motrice constituante de ce « moteur à pression ».According to the invention, the hydromechanical transformation of the antagonistic forces into a continuous gyratory movement is obtained mechanically by virtue of the introduction of an iterative imbalance positioning of the said floating bodies in such a way that they renew both their rotation in a trajectory can be for example epicyclic and the central rotation of the pivoting carrier structure (mast). All of these circular motions thus allow the sustainable capture of a part of the energy in order to transform it into a driving source constituting this "pressure engine".
L'invention va être mieux définie sur la base d'un exemple non limitatif de réalisation de cette motorisation.The invention will be better defined on the basis of a non-limiting embodiment of this engine.
Le dispositif est placé au centre d'un réservoir circulaire, lequel est rempli d'eau.The device is placed in the center of a circular tank, which is filled with water.
Dans le but de permettre le captage hydromécanique de la poussée d'Archimède, plusieurs vis de convoyage de type « vis d'Archimède » creuses, pleines d'air, flottantes et pivotantes, sont immergées ; celles-ci, solidaires des bras d'une structure porteuse telle qu'un mât elle-même pivotante, sont disposées, de préférence de façon inclinée, et sont d'autre part maintenues en contact avec une ligne de guidage horizontale constituée par le pourtour inférieur de la paroi interne du réservoir.In order to allow hydromechanical capture of the Archimedes thrust, several hollow, full-air, floating and pivoting "screw Archimedes" type conveying screws are immersed; these, integral with the arms of a supporting structure such as a mast itself pivoting, are arranged, preferably inclined, and are further maintained in contact with a horizontal guide line constituted by the periphery bottom of the inner wall of the tank.
Grâce à la réalisation de cette motorisation, la différence entre les forces de poussée permet d'obtenir la mise en rotation de chacune des dites vis, qui entraînent à leur tour la rotation du mât : une partie de l'énergie récupérée est alors transformée en source motrice, puis en source d'énergie électrique, sans pollution ni consommation de matières périssables ou d'énergie fossile.Thanks to the realization of this motorization, the difference between the thrust forces makes it possible to obtain the rotation of each of said screws, which in turn cause rotation of the mast: part of the energy recovered is then transformed into a source of power, then a source of electrical energy, without pollution or consumption of perishable matter or fossil energy.
La figure 1 montre le dispositif selon l'invention. Il comporte un mât fixe (1) reposant sur un socle massif (2). Il porte à son sommet une articulation (3) comportant une tige verticale (4) insérée au sommet du mât (1), tournant à l'intérieur d'un embout fixe (5). Cette tige (4) reçoit deux axes parallèles (6) (6') assujettis à la tige par un dispositif de solidarisation (7) du type clavette ou écrous ou écrous papillons. A l'autre extrémité, les deux axes (6) (6') viennent se fixer à la partie supérieure d'une tige (8) placée au centre du dispositif hélicoïdal (9) en position inclinée. Le dit dispositif hélicoïdal est placé au centre d'un réservoir rempli d'eau ou d'un liquide aqueux sur le fond duquel il repose. Le dispositif hélicoïdal (9) entraîne la rotation du mât (1) et amène ainsi la production d'énergie qui peut être utilisée ou récupérée.Figure 1 shows the device according to the invention. It comprises a fixed mast (1) resting on a solid base (2). It carries at its summit a joint (3) comprising a vertical rod (4) inserted at the top of the mast (1), rotating inside a fixed end (5). This rod (4) receives two parallel axes (6) (6 ') secured to the rod by a securing device (7) of the key type or nuts or wing nuts. At the other end, the two axes (6) (6 ') are fixed to the upper part of a rod (8) placed in the center of the helical device (9) in an inclined position. The said helical device is placed in the center of a reservoir filled with water or an aqueous liquid on the bottom of which it rests. The helical device (9) causes rotation of the mast (1) and thus provides the production of energy that can be used or recovered.
L'inclinaison du dispositif hélicoïdal est un facteur important qui conditionne la mise en rotation. Un angle d'inclinaison de 5 à 45° est préféré et surtout de 30 à 40°. La figure 2 montre le dispositif hélicoïdal (9) vu par au-dessus avec les différentes branches (10) (10') (10") vues en surplomb.The inclination of the helical device is an important factor that conditions the rotation. An inclination angle of 5 to 45 ° is preferred and especially 30 to 40 °. Figure 2 shows the helical device (9) seen from above with the various branches (10) (10 ') (10 ") overhanging.
Le dispositif hélicoïdal (9) est réalisé de préférence en une matière plastique solide mais suffisamment souple. Le matériau optimal est le polystyrène choc. Il peut être remplacé par du polyéthylène HD ou du polypropylène ou toute autre matière plastique ayant des qualités équivalentes.The helical device (9) is preferably made of a solid plastic material but sufficiently flexible. The optimal material is shock polystyrene. It can be replaced by HD polyethylene or polypropylene or any other plastic material with equivalent qualities.
La figure 3 montre d'une manière plus détaillée le dispositif hélicoïdal (9) à trois étages (11 ) (11 ') (11 ") ayant une hauteur de 20 à 25 cm — de préférence de 24 à 25 cm — , une section d'environ 40 mm, pourvu d'ailerons épicycloïdaux de 80 mm hors tout.FIG. 3 shows in more detail the three-stage helical device (9) (11) (11 ') (11 ") having a height of 20 to 25 cm, preferably 24 to 25 cm, a section approximately 40 mm, provided with planetary 80 mm planetary fins.
La figure 4 montre le détail de la rotation des motifs épicycloïdaux (12) (12') (12") autour de la tige centrale (8). Ces motifs épicycloïdaux sont réalisés en une matière plastique dure, qui soit résistante aux chocs et à la rotation. Ils se présentent sous la forme de rubans incurvés se déplaçant dans le liquide porteur en réalisant en position inclinée un brassage énergique du liquide. Les deux articulations (8) et (8') sont nécessaires pour la transmission du mouvement à la tige 1. Figure 4 shows the detail of the rotation of the epicyclic units (12) (12 ') (12 ") around the central rod (8) These epicyclic units are made of a hard plastic material, which is resistant to shocks and vibrations. They are in the form of curved ribbons moving in the carrier liquid, making an energetic mixing of the liquid in an inclined position.The two articulations (8) and (8 ') are necessary for the transmission of the movement to the stem. 1.
EXEMPLE D'APPLICATIONSEXAMPLE OF APPLICATIONS
Parmi les applications et développements que permet d'envisager le présent dispositif, il existe notamment la possibilité de créer un « électrogénérateur à induction magnétique » : en fait, un disque magnétisé faisant office de rotor qui peut être entraîné par l'arbre de transmission (mât) du présent « moteur à pression» et qui, grâce à la rotation du dit disque, crée un champ magnétique tournant et sans contact. Il peut à son tour alimenter un collecteur faisant office de stator. Ce dispositif ainsi adapté permet ainsi la production par induction de courant électrique. Par ailleurs, le présent dispositif permet de développer une autre application (laquelle peut éventuellement être complémentaire de la précédente) ; à savoir un « générateur atmosphérique d'eau potable ». En effet, l'introduction d'un produit réfrigérant à l'intérieur d'un contenant où est placé le dit « moteur à pression» permet par la rotation des corps flottants de provoquer le refroidissement du dit fluide; la différence thermique entre ce fluide ainsi refroidi et l'air ambiant a pour effet de fixer les multiples particules d'eau qui y sont contenues sur la paroi externe du réservoir, où celles-ci peuvent être recueillies en tant qu'eau de préférence potable.Among the applications and developments that the present device makes it possible to envisage, there exists in particular the possibility of creating a "magnetic induction generator": in fact, a magnetized disk acting as a rotor which can be driven by the transmission shaft ( mast) of the present "pressure motor" and which, thanks to the rotation of said disk, creates a rotating magnetic field and without contact. It can in turn feed a collector acting as a stator. This device thus adapted allows the production by induction of electric current. Moreover, the present device makes it possible to develop another application (which may possibly be complementary to the previous one); namely an "atmospheric generator of drinking water". Indeed, the introduction of a refrigerant inside a container where is placed the said "pressure motor" allows the rotation of the floating bodies to cause the cooling of said fluid; the thermal difference between the fluid thus cooled and the ambient air has the effect of fixing the multiple water particles contained therein on the outer wall of the tank, where they can be collected as preferably drinking water .
L'invention trouve une application supplémentaire dans le fait que le présent dispositif peut servir de générateur de luminescence. En effet l'insertion d'un produit luminescent ou phosphorescent à l'intérieur d'un contenant dans lequel on place le moteur à pression selon l'invention permet, par la rotation des corps flottants, de provoquer la luminescence du fluide contenu dans le réservoir. On réalise ainsi une possibilité d'utilisation dans le domaine de l'éclairage. The invention finds an additional application in that the present device can serve as a luminescence generator. Indeed, the insertion of a luminescent or phosphorescent product inside a container in which the pressure motor is placed according to the invention makes it possible, by the rotation of the floating bodies, to cause the luminescence of the fluid contained in the tank. This provides a possibility of use in the field of lighting.
