Title
(EN) SELF-CLEANING UNDERWATER INSTRUMENTATION
(FR) APPAREILLAGE SUBAQUATIQUE AUTONETTOYANT
Abstract
(EN)
Techniques and apparatus inhibit, limit, or remove biofouling and certain inorganic accumulations, to increase the longevity of accurate in-situ oceanographic and other underwater measurements. The invention deters formation of an initial bacterial layer and other precipitation, without harming the environment. The invention integrates an ultrasonic source (24) into a sensor or other device, or its supporting structures. The ultrasonic source vibrates one or more critical surfaces (12) of the device at a frequency and amplitude that dislodge early accumulations, thus preventing the rest of the fouling sequence. The ultrasonic driver is activated for short periods and low duty cycles, and in some cases preferably while the device is not operating.
(FR)
L'invention concerne des techniques et un appareil qui inhibent, limitent ou éliminent l'encrassement biologique et certaines accumulations inorganiques, afin d'augmenter la longévité de mesures précises océanographiques in situ et d'autres mesures subaquatiques. L'invention permet d'empêcher la formation d'une couche bactérienne initiale et d'autres précipitations, sans nuire à l'environnement. L'invention intègre une source d'ultrasons dans un capteur ou autre dispositif, ou ses structures de support. La source d'ultrasons fait vibrer une ou plusieurs surfaces critiques du dispositif à une fréquence et à une amplitude qui délogent des accumulations précoces, empêchant ainsi le repos de la séquence d'encrassement. Le dispositif de commande d'ultrasons est activé pendant de courtes périodes de temps et à des cycles opératoires faibles, et dans certains cas, de préférence, pendant que le dispositif n'est pas en fonctionnement.
