Bottom-exploration zigzag-type deep sea submerged buoy system

Abstract

The invention discloses a bottom-exploration zigzag-type deep sea submerged buoy system which comprises a spherical pressure-resisting cabin and a trigger action mechanism, wherein the bottom of the spherical pressure-resisting cabin of a submerged buoy body is provided with the trigger action mechanism, thus the submerged buoy which is vertically submerged to the bottom of the sea starts the trigger action mechanism at the instant of contacting the bottom, sea bottom sampling is finished and loads are released and thrown, the submerged buoy floats upward so as to complete the acquisition of vertical section information of a sea water column from the sea level to the sea bottom for the deep submerged section floating buoy; the spherical pressure-resisting cabin is formed by the connection of upper and lower semispherical end covers through bolts; the trigger action mechanism comprises an injector-type sampling mechanism, a throwing and loading mechanism and a deep bottom trigger mechanism; the top of the semispherical upper end cover of the spherical pressure-resisting cabin is provided with a thermohaline deep measuring transducer; and cameras are installed in camera holes which are uniformly distributed circumferentially on the semispherical lower end cover. The bottom-exploration zigzag-type deep sea submerged buoy system disclosed by the invention is simple in structure, low in cost and reliable in operation; and complete water column images and water quality information from the sea water level to the bottom of the ocean can be recorded, and substance sampling at the sea bottom can be realized, and a new prospect is developed in the applications of marine environmental monitoring for the deep submerged section floating buoy.

Description

technical field [0001] The invention relates to a marine surveying device, in particular to a profile measuring device for deep-sea submerged buoys. Background technique [0002] At present, deep-diving profiling buoys, as a continuously developing ocean profile measurement device, have become one of the important technical means for marine environment monitoring. The submersible body of the deep-diving profile buoy is equipped with measurement sensors, data recording devices and communication devices. The buoyancy pump is arranged in the submersible body, and the buoyancy pump adjusts the underwater displacement of the submersible body to adjust its underwater buoyancy. The submersible body dives from the sea surface by its own weight, and after diving to a certain depth, it rises under the buoyancy adjusted by the buoyancy pump. During the dive and ascent of the submersible body, the vertical profile information of the marine environment is measured and recorded for the t...

AI Technical Summary

Problems solved by technology

[0003] Existing deep-diving profile buoys use buoyancy pumps to adjust the underwater buoyancy of the submersible body to achieve its profile movement. However, the range of profile movement is limited. Generally, it travels back and forth between the sea surface and the depth of 2000 meters, and the measurement of the deep sea and the seabed cannot be realized.

Moreover, the buoyancy pump and its buoyancy adjustment body mechanism are relatively complicated, and any small difference in buoyancy adjustment will affect the underwater measurement of the deep-diving profile buoy
