Abstract[English]
This invention provides a novel system for preventing marine biofouling on vessel propellers and shafts using a shaft-mounted ultrasonic transducer collar. The system generates ultrasonic energy parallel to the propeller shaft, ensuring uniform and efficient energy distribution for effective biofouling prevention. The collar integrates multiple high-power ultrasonic transducers, each equipped with an internal circuit board for individual control and communication via power cables through a slip ring. The slip ring facilitates the transfer of power without impeding the shaft's rotation. The system employs various ultrasonic waveforms, including continuous, pulsed, and frequency-modulated waves, to maximize energy throughput and adaptability. This innovative configuration reduces maintenance needs, enhances vessel efficiency, and provides a robust, environmentally friendly solution for marine biofouling prevention.[French]
La présente invention concerne un nouveau système permettant d'empêcher l'encrassement biologique marin sur des hélices et des arbres de navire à l'aide d'un collier de transducteur ultrasonore monté sur arbre. Le système génère une énergie ultrasonore parallèle à l'arbre d'hélice, ce qui permet d'assurer une distribution d'énergie uniforme et efficace pour une prévention efficace de l'encrassement biologique. Le collier intègre de multiples transducteurs ultrasonores haute puissance, chacun étant équipé d'une carte de circuit imprimé interne pour une commande et une communication individuelles par l'intermédiaire de câbles d'alimentation à travers une bague collectrice. La bague collectrice facilite le transfert d'énergie sans entraver la rotation de l'arbre. Le système utilise diverses formes d'onde ultrasonores, comprenant des ondes continues, pulsées et modulées en fréquence, afin de maximiser le débit d'énergie et l'adaptabilité. Cette configuration innovante réduit les besoins de maintenance, améliore l'efficacité du navire et fournit une solution robuste et respectueuse de l'environnement pour la prévention de l'encrassement biologique marin.
