Device for salvaging and reclaiming underwater object

Номер: CN0101628615A
Принадлежит:

The invention discloses a device for salvaging and reclaiming an underwater object, which comprises a base, an air bag, an air bottle and an air supply pipe system. The air bag is fixed on the base, the air bottle is fixed in the air bag, and the air bag is connected with the air bottle through the air supply pipe system; and when an underwater detection apparatus needs to be reclaimed, the air bag is inflated by the air bottle, the holding capacity of the air bag is continuously increased to generate certain positive buoyancy and carry the underwater detection apparatus to float towards the water surface. The device can be integrated with the underwater detection apparatus through butt joint or binding, so the device can be flexibly applied to different occasions, and has compact structure and convenient use.

Base type observation platform and laying and recycling method thereof

Номер: CN116080826A
Принадлежит:

The invention discloses a base type observation platform and a laying and recycling method thereof. The observation platform comprises a ballast anchor assembly and a platform assembly installed on the ballast anchor assembly. The ballast anchor assembly is used for stably bringing the platform assembly into a seabed when the observation platform enters water; the platform assembly comprises a seabed observation device, a flow guide body, a platform base, an acoustic releaser and a communication buoy. The design thought of combining modularization and embedded type is adopted, it can be guaranteed that after the base type observation platform enters water, the ballast anchor is stably sunk into the seabed, the base type observation platform can adapt to the severe ocean environment, and when recycling is needed after the work cycle is completed, seabed observation equipment on the observation platform emerges from the water surface.
