| The observation and calculation of ocean currents have become an indispensable part of marine engineering construction. How- ever, when encountering shallow water currents in ports and docks, the observation methods face significant challenges. This article pro- poses an automatic compensation technology for the attitude of ocean current observation instruments based on different seabed topographies, and designs an automatic compensator for ocean current observation instruments, effectively solving the problem of observation failure caused by the influence of seabed slope. This paper introduces the basic principles, main structures, component designs, and installation methods of an automatic compensator for current observation instruments. This device is equipped with various acoustic Doppler cur rent profilers (ADCP), automatic compensation, anti-trawl, and fully submerged structures, which enable it to rest stably on the seafloor. These bottom measurement systems can be used for nearly non-disturbed and long-term investigations on the seafloor. The research shows that , The research shows that the device incorporates an automatic inclination compensation system, maintaining ADCP and other observational instruments in a vertical orientation to ensure data validity. It also offers excellent versatility, supporting various models and specifications of ADCP. Additionally, it exhibits strong anti-trawling capabilities, which effectively prevent various fishing boats 爷 trawls and drift nets from damaging the device and its onboard ADCP, and other instruments and equipment. This device provides a new means for current observation on uneven seabeds, particularly in environments where storm currents, shallow waters, and sand waves frequently move. It has been successfully applied to nearshore current observation in multiple ports, wharves, wind farms, ecological restoration, and other projects. |
