Background technique

With the continuous development of the seabed monitoring platform, its working area has expanded from shallow seas to deep seas, sampling and monitoring seabed sediments or overlying water. The existing submarine monitoring platforms are mainly deployed with cables, and some use cable-free submarine monitoring systems. In order to meet the needs of deep-sea monitoring, some marine scientific expedition teams currently rely on advances in science and technology to mount existing monitoring devices on submersibles, and use manned submersibles or unmanned submersibles to bring measurement devices into the deep sea. And deployed to the seabed area for scientific research. Although this monitoring method is highly flexible, it has the disadvantages of extremely high cost and not suitable for long-term continuous monitoring, so its applicability is poor. If a cable-free subsea monitoring device is used, its deployment, settlement, landing and dumping, floating and recovery are essential to the smooth completion of the monitoring operation. Due to the complicated subsea conditions, the stability of the heavy block release device is difficult to guarantee.
