Description

Recovery device and recovery method for submersible target with releaser failure

technical field

The invention belongs to the field of ocean observation, in particular to a recovery device and a recovery method for a submersible buoy whose releaser fails.

Background technique

The submersible buoy system is an important technical equipment for marine environmental investigation. It has the capability of unattended long-term, continuous, synchronous and automatic comprehensive monitoring of various elements such as ocean current, water temperature and salinity in the ocean section under harsh marine environmental conditions. It is characterized by the extension of ocean observation shore stations, survey ships and survey aircraft in space and time, and is an important means of offshore monitoring, which has an irreplaceable role in other survey methods; and has good concealment and is not easy to be destroyed Its advantages have been widely used, and its importance has been paid more and more attention by various marine countries in the world. After the submersible buoy system has been working at sea for a long time, due to external reasons such as biological adhesion and fishing net entanglement, or the releaser's own reasons such as power exhaustion and signal reception failure, the releaser decoupling failed. However, the submarine buoy observation data is precious and the submersible buoy itself is expensive, so it is necessary to salvage and recover the submersible buoy whose releaser fails. At present, most of the recovery of the releaser failure submersible is to find divers to dive into the hook to recover. Professional re-diving is not only expensive, but also risky; in addition, professional heavy-duty divers cannot dive in deeper sea areas. If a heavy-duty ROV (remotely operated unmanned submersible) is used, the heavy-duty ROV is not only expensive, but also difficult to find, and requires skilled ROV operators and professional scientific research mother ship support, which is expensive and difficult to implement.
