Disposable underwater temperature-salinity-depth measuring device carried on underwater vehicle

Abstract

The invention belongs to the technical field of ocean observation, and relates to a disposable underwater temperature-salinity-depth measuring device carried on an underwater vehicle. The invention discloses a disposable underwater temperature-salinity-depth measuring device carried on an underwater vehicle. The disposable underwater temperature-salinity-depth measuring device comprises a split shell, a front-end floater, a rear-end floater, a CTD sensor and a control panel, the lower portion of the front-end floater is connected with a bottom end cover, a split shell is arranged outside the rear-end floater, and the split shell is connected with the bottom end cover in a matched mode through a connecting mechanism. The CTD sensor is in watertight connection with the top of the front-end floater; a pressure triggering mechanism is arranged in the front-end floater; the pressure triggering structure comprises a screw rod seat, a movable screw rod and a cam screw rod; the screw seat is hermetically connected with the bottom end cover, and the bottom end cover is hermetically connected with the front-end floater in sequence to form a watertight space; the control panel is installed in the watertight space. The device is launched through an underwater vehicle, temperature-salinity-depth measurement of a water body profile is completed in the floating process, and measurement data is transmitted to the underwater vehicle; and disassembling and discarding after measurement is completed.

Description

technical field [0001] The invention belongs to the technical field of ocean observation, and in particular relates to an abandoned underwater temperature and salinity measuring device mounted on an underwater vehicle. Background technique [0002] At present, different monitoring methods are used for ocean monitoring with different needs. For application scenarios that require all-weather monitoring, seawater buoy monitoring is used. For application scenarios that need to measure ocean water profile detection, measurement methods such as ARGO buoys or submarine buoys are usually used. The monitoring of meteorological forecasts and natural disasters adopts marine monitoring methods such as satellites and ships. [0003] Using ARGO buoys or submersible buoys to measure the ocean profile, the equipment needs to float to the surface or expose the communication antenna to the water surface before it can send the water measurement data to the shore-based platform. ARGO buoys a...
