Abstract
Description
Dispositif propulseur marin utilisant les effets de tangage et de roulis. Marine propellant device using the effects of pitch and roll.
Il est destiné à assurer la propulsion des embarcations en avant en n 'utilisant pour seule énergie que les mouvements ascendants et descendants que la force des flots imprime au navire. It is intended to ensure the propulsion of boats forward using only for energy that the upward and downward movements that the force of the waves imprints on the ship.
Il est connu d'utiliser pour assurer l'avancement des embarcations des propulseurs de toutes sortes et même des palmes de natation montées sur tiges qui par une alternance de mouvements imprimés musculairement telles des godilles ou autres forces motrices permettant le déplacement de l'embarcation. It is known to use to ensure the advancement of boats thrusters of all kinds and even swimming fins mounted on rods which by an alternation of muscularly printed movements such as sculls or other driving forces allowing the movement of the boat.
Le dispositif suivant l'invention supprime l'emploi d'une force musculaire ou autre et permet d 'utiliser le balancement et le mouvement d'abaissement ou de relèvement de la coque pour capter ces effets et les transformer à 1' aide de palmes en force motrice d'avancement. The device according to the invention eliminates the use of muscular or other force and makes it possible to use the rocking and the lowering or raising movement of the hull to capture these effects and transform them with the aid of fins. driving force for advancement.
I1 est constitué par la combinaison de convertisseurs d'énergie formés par des armatures rigides positionnant des palmes souples et élastiques avec un circuit hydraulique comportant des vérins à double effet avec électro-vanne. I1 consists of the combination of energy converters formed by rigid frames positioning flexible and elastic fins with a hydraulic circuit comprising double-acting cylinders with solenoid valve.
Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
a figure 1 représente le dispositif dans son ensemble vu en élévation et en coupe longitudinale.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
a Figure 1 shows the device as a whole seen in elevation and in longitudinal section.
La figure 2 montre dans les mêmes conditions la vue en coupe d'un élément propulseur. Figure 2 shows in the same conditions the sectional view of a propellant.
Les figures 3 et 4 sont des vues en coupe d'un mode d'application du propulseur sur une embarcation. Figures 3 and 4 are sectional views of a mode of application of the propellant on a boat.
Le dispositif, figures 1 et 2, est constitué par un chassis carréné 1 en matériau résistant. The device, FIGS. 1 and 2, is constituted by a faired chassis 1 made of resistant material.
11 permet la fixation de l'ensemble sous la coque d'une embarcation. 11 allows the assembly of the assembly under the hull of a boat.
Les convertisseurs d'énergie 2, 3 sont réalisés par des éléments rigides en forme de nageoires montés d'une part sur les axes 4, 5 et reliés d'autre part aux vérins à double effet 6, 7 dont l'un des circuits 8, 9 comporte une électro-vanne de réglage 10 servant à ouvrir et fermer le circuit hydraulique. The energy converters 2, 3 are produced by rigid elements in the form of fins mounted on the one hand on the axes 4, 5 and connected on the other hand to the double-acting cylinders 6, 7 of which one of the circuits 8 , 9 comprises an electric control valve 10 used to open and close the hydraulic circuit.
Le corps de nageoire 11, 12 enveloppant l'ensemble est constitué en matière souple et élastique tel du caoutchouc. The fin body 11, 12 enveloping the assembly is made of flexible and elastic material such as rubber.
Il établit un pont entre les deux convertisseurs 2, 3.It establishes a bridge between the two converters 2, 3.
Le dispositif réalise une sorte de palme 14 à à ailes déformables 16, 17 dont les effets sont comparables à ceux obtenus par une nageoire codale, fig 3, 4. The device produces a sort of palm 14 with deformable wings 16, 17 whose effects are comparable to those obtained by a codal fin, fig 3, 4.
Elle se fixe par sa monture 1 dans l'axe de la coque 13 de part et d'autre de la quille 15. It is fixed by its mount 1 in the axis of the shell 13 on either side of the keel 15.
Ce propulseur une fois fixé sous l'embarcation est soumis par sa voilure à des forces contraires produites par les tangages et roulis de sorte que le poids de la masse d'eau déplacée l'allège à suivre ses oscillations. This propellant once fixed under the boat is subjected by its wing to contrary forces produced by the pitching and rolling so that the weight of the displaced body of water alleviates it to follow its oscillations.
Si l'embarcation A oscille par sa droite, le convertisseur B situé en dessous en se mouvant comprime son vérin qui met alors en mouvement 1' autre convertisseur. If boat A oscillates on its right, the converter B located below while moving compresses its cylinder which then sets in motion the other converter.
C'est l'action conjuguée de ces deux convertisseurs qui actionne la nageoire qui décrit alternativement une courbe sinusoïdale motrice. It is the combined action of these two converters which actuates the fin which alternately describes a sinusoidal driving curve.
Lorsqu'on désire arrêter la propulsion il suffit de fermer le circuit hydraulique à l'aide de 1 'électro-vanne 10 qui immobilise les vérins. When it is desired to stop the propulsion, it suffices to close the hydraulic circuit using the solenoid valve 10 which immobilizes the jacks.
Toutefois les formes, dimensions et dispositions des différents éléments comme d ' ailleurs les matières utilisées pour leur fabrication pourront varier dans lalimite des équivalents, sans changer pour celal, la conception générale de l'invention qui vient d'être décrite. However, the shapes, dimensions and arrangements of the various elements, as moreover the materials used for their manufacture, may vary within the limit of equivalents, without changing to that, the general design of the invention which has just been described.
