A deep-sea bottom-seat observation station that can be automatically recovered

Abstract

The invention discloses a deep sea bottom-supported observation station capable of being automatically recovered and relates to the technical field of seabed landing, releasing and recovery. The deepsea bottom-supported observation station capable of being automatically recovered comprises a buoyancy recycling system; guide columns are arranged at the top end of a bottom-supported bracket system;the guide columns and the buoyancy recycling system are slidingly arranged; a tensioning nut is arranged on the buoyancy recycling system; a spring sleeves the guide column; one end of the spring abuts against the tensioning nut; the other end of the spring abuts against the bottom-supported bracket system; a shaft seat remaining piece is fixedly arranged on the bottom-supported bracket system; aslide groove is formed in the bottom end of the shaft seat remaining piece; an acoustic release transponder is fixedly arranged under the buoyancy recycling system; one end of an anchor chain is arranged on the acoustic release transponder; the two ends of a rotating ring are arranged at the free end of the anchor chain in a sleeving manner; a pin shaft is fixedly arranged on the rotating ring; and the pin shaft is slidingly arranged in the slide groove of the shaft seat remaining piece. The deep sea bottom-supported observation station capable of being automatically recovered has the beneficial effects that the impact borne on an expensive apparatus during landing on the seabed can be reduced to guarantee that the apparatus can be normally used during landing and the buoyancy recycling system can also be released and recovered; and the reuse of the apparatus can also be guaranteed.

Description

technical field [0001] The invention relates to the technical field of seabed landing, release and recovery, in particular to a deep sea bottom observation station that can be automatically recovered. Background technique [0002] The tripod is a precious instrument equipped with cross-sectional ocean currents, acoustic release devices, temperature-salt-depth turbidimeters, single-point ocean currents and other water-tight body precision detection. It is pulled by a 1200-kg counterweight on the bottom support system and runs at a rate of 1 m / s. It is a kind of equipment for in-situ observation by freely sinking into the seabed at a depth of 6,000 meters. Its open structure design can carry various instruments such as high-precision and high-frequency acoustics and optics, and conduct long-term, stable and self-contained in-situ observations of physical, chemical, geological and biological parameters of the bottom boundary layer. Expensive instruments cannot withstand large ...

Problems solved by technology

[0003] Sediment will be attached to the release and recovery device on the deep-sea bottom observation station for a long time. At the same time, the cabin body must withstand the pressure of 60MAP. Some materials will be electrolyzed and turbidly corroded by seawater, and rise from the seabed to the sea surface. The risk of deployment and recovery larger
