La présente invention concerne un dispositif permettant d'optimiser les réglages en termes de gîte et d'assiette de certains voiliers, chaque voilier étant conçus pour avoir ses meilleures performances en ayant un angle de gîte déterminé tout en restant dans ses lignes longitudinales. Certaines conditions de navigation impliquent que tous ces paramètres ne peuvent pas être maintenus de manière idéale en continu. Ces corrections sont habituellement réalisées de deux manières différentes ; soit grâce à l'utilisation de ballasts latéraux et/ou longitudinaux qui permettent d'apporter et de l'inertie et/ou un couple de redressement plus/ou moins important au bateau ; soit par le pivotement de la quille lestée de plomb qui augmente/ou diminue le couple de redressement du bateau. Le deux techniques abordées ci-dessus peuvent être employées simultanément. Le dispositif pourra être adapté à tout voilier muni d'une quille pivotante et équipé ou non de ballasts qu'il remplace avantageusement. Il comporte selon une première caractéristique une série de capteurs d'inclinaison et d'incidence qui renseignent en permanence un calculateur des conditions d'équilibre du voilier. Ce calculateur analyse les données recueillies et lorsque certaines valeurs sont atteintes depuis plus d'un certain temps, des électrovannes commandent l'action de vérins qui agissent alors sur la quille afin d'obtenir les paramètres du niveau recherché. Le réglage d'incidence de la quille pourra apporter une augmentation du couple de redressement et permettra l'élimination du plan porteur parfois créé par les mouvements du bateau. La puissance hydraulique sera fournie soit par une centrale hydraulique à moteur thermique pour un service en continu soit par une pompe électrique sur batterie pour un rythme de mesures cyclique. La force motrice sera obtenue par un moteur hydraulique couplé à une hélice. Lorsque les valeurs maximales de déport de quille sont atteintes, le calculateur stoppe tout ordre visant à augmenter ces dernières. En cas de retournement à 180 , le système positionne automatiquement la quille afin d'obtenir le couple de redressement maximal. Le dispositif peut être activé ou désactivé à tout moment ; les derniers paramètres étants conservés jusqu'à la remise en route du dispositif. Le système informatique peut fonctionner en mode manuel, l'utilisateur rentrant alors lui-même ses propres paramètres. The present invention relates to a device making it possible to optimize the settings in terms of heel and trim of certain sailboats, each sailboat being designed to have its best performance by having a determined heel angle while remaining within its longitudinal lines. Certain conditions of navigation imply that all these parameters cannot be maintained in an ideal way continuously. These corrections are usually made in two different ways; either through the use of lateral and / or longitudinal ballasts which make it possible to provide inertia and / or more / or less righting torque to the boat; either by the pivoting of the lead weighted keel which increases / or decreases the righting torque of the boat. The two techniques discussed above can be used simultaneously. The device could be adapted to any sailboat provided with a pivoting keel and equipped or not with ballasts which it advantageously replaces. According to a first characteristic, it comprises a series of tilt and incidence sensors which permanently inform a computer of the equilibrium conditions of the sailboat. This computer analyzes the data collected and when certain values have been reached for more than a certain time, solenoid valves control the action of jacks which then act on the keel in order to obtain the parameters of the desired level. Adjusting the angle of attack of the keel will bring about an increase in the righting moment and will allow the elimination of the bearing plane sometimes created by the movements of the boat. Hydraulic power will be supplied either by a hydraulic central unit with thermal engine for continuous service or by an electric pump on battery for a cyclic measurement rhythm. The driving force will be obtained by a hydraulic motor coupled to a propeller. When the maximum keel offset values are reached, the computer stops any order to increase them. In the event of a 180 turn, the system automatically positions the keel in order to obtain the maximum righting torque. The device can be activated or deactivated at any time; the last parameters being kept until the device is restarted. The computer system can operate in manual mode, the user then entering his own parameters himself.
Une fonction Remise à Zéro réinitialise les paramètres à l'état neutre défini pour chaque type de voilier. A Reset function resets the parameters to the neutral state defined for each type of sailboat.
En cas de non fonctionnement du groupe hydraulique ; un système manuel permet de fournir la puissance hydraulique aux vérins. Le réglage des vérins peut s'effectuer manuellement. Une soupape de sécurité tarée à une valeur définie permet d'amortir un choc de la quille avec un corps immergé. In the event of failure of the hydraulic unit; a manual system provides hydraulic power to the cylinders. The cylinders can be adjusted manually. A safety valve calibrated to a defined value makes it possible to absorb a shock from the keel with a submerged body.
Selon des modes particuliers de réalisation : Le système de rotation de la quille pourra être un de ceux déjà existant ; le dispositif étant adaptable à chacun d'eux qu'il soient à un, deux ou trois axes. Les capteurs de gîte et d'assiette peuvent être placés à tout endroit ou les conditions de mesure sont similaires quel que soit le bord sur lequel se trouve le bateau, l'emplacement initialement prévu étant sur le puits de quille. Les capteurs d'incidence sont placés sur la quille, à proximité immédiate du dauphin de lest. Les groupes de pression hydraulique pourront être placés à tout endroit judicieusement choisi, tout en veillant à ne pas allonger outre mesure le circuit de distribution hydraulique. Les débits d'huile adaptés à celle des vérins, leur dimensionne- According to particular embodiments: The keel rotation system could be one of those already existing; the device being adaptable to each of them whether they are one, two or three axes. The heel and trim sensors can be placed at any location or the measurement conditions are similar regardless of the edge on which the boat is located, the location initially planned being on the keel well. The incidence sensors are placed on the keel, in the immediate vicinity of the sinker dolphin. The hydraulic pressure groups can be placed in any judiciously chosen location, while taking care not to overly lengthen the hydraulic distribution circuit.
