Description

Transducer surface cleaning mechanism of ADCP Technical Field The utility model relates to the technical field of acoustic Doppler flow velocity profilers, in particular to an ADCP transducer surface cleaning mechanism. Background Acoustic doppler flow profiler (ADCP) is a device that measures flow velocity in a body of water using acoustic principles. It works based on the doppler effect by transmitting sound waves and receiving sound waves reflected back by particles in the water to calculate the speed and direction of the water flow. Existing acoustic doppler flowmeters are provided with one or more transducers, which are the core components of the acoustic doppler flowmeters. Because acoustic doppler flowmeters are immersed in water (fresh water or sea water) for a long period of time, sediment, dirt, or some micro-organisms (e.g., algae, etc.) can deposit on the surface, which can cause the surface of the transducer on the ADCP to be masked, resulting in its inability to work properly.
