Abstract

The invention discloses an on-line real-time ultrasonic cleaning device for ocean underwater lenses based on an MEMS ultrasonic transducer array. The ultrasonic cleaning device adapts the MEMS ultrasonic transducer array with small size, low energy consumption, and easy integration; multiple ultrasonic transducer array modules are evenly and circumferentially arranged on a circular base; each transducer unit in the transducer array modules can work independently; the on-line real-time or regular cleaning of ocean underwater lenses can be realized; and the working state of any transducer unit in the ultrasonic transducer array and the number of the working transducer array modules can be controlled according to an actual situation, accordingly the radiant surface of the ultrasonic cleaningcan be changed, and cleaning is efficient and energy consumption can be reduced at the same time.

Description

technical field [0001] The invention relates to an ultrasonic cleaning device based on a microelectromechanical (MEMS) ultrasonic transducer array, in particular to an online real-time ultrasonic cleaning device for lenses of underwater monitoring equipment such as marine underwater cameras. Background technique [0002] The detection and research of the ocean is not only the need to develop the national marine economy, but also the basis for protecting the ocean and achieving sustainable development. Underwater surveillance equipment such as underwater cameras plays an important role in marine underwater operations and marine scientific research. Then due to marine biofouling, the surface of any object put into seawater will soon be covered by a layer of biofilm, and the biofilm attached to the surface of sensitive components of underwater camera lenses and other monitoring equipment will affect the normal operation of the equipment use. [0003] Effective anti-fouling mea...
