The present study is part of a global project which consists in the development of an automatic cleaning station for immersed boats (cockle, ninepin, etc.) in a self-service mode, associating an innovative ultrasonic device for cleaning with a specific water treatment. The originality of the process is that cleaning is performed by three transducers operating simultaneously at low frequency and moving along the surface, thanks to programmable logic controllers, and that it includes a suction to collect the dirt removed. Therefore, the time required for boat maintenance is shortened, ensuring high quality cleaning without the need for dry docks and avoiding additional pollution in the harbor areas. One of the key points was the evaluation of washing efficiency, as it is really hard to give a quantitative estimation of the dirt removed. To obtain the first design laws, feasibility tests have been carried out on dirty cockle samples and on real boat hulls with a laboratory ultrasonic device. The influence of a large number of parameters was tested such as transducer-probe distance, displacement speed and transmitted power. The obtained data allowed us to design an optimized cleaning device combining high efficiency and speed.
本研究是一个全球项目的一部分，该项目旨在开发一种自动清洗站，用于自助式浸没式船只（贻贝、九柱戏等），结合创新的超声波清洗设备和特殊的水处理。该过程的新颖之处在于，清洗由三个同时在低频运行并沿表面移动的换能器完成，这要归功于可编程逻辑控制器，并且包括一个吸力来收集清除的污垢。因此，缩短了船只维护时间，确保了高质量的清洗，无需干船坞，并避免了港口区域的额外污染。其中一个关键点是评估清洗效率，因为很难对去除的污垢进行定量估计。为了获得第一个设计定律，在实验室超声波设备上对脏贻贝样本和真实船体进行了可行性测试。测试了大量参数的影响，如换能器探头距离、位移速度和传输功率。获得的数据允许我们设计一个高效和快速的优化清洗装置。
