Automatic falling-off device for flow guide shell of self-sinking and floating type section detection buoy and flow guide shell

Abstract

The invention belongs to the technical field of marine environment monitoring, and particularly relates to an automatic falling-off device for a flow guide shell of a self-sinking and floating type section detection buoy and the flow guide shell. An automatic falling-off device for a flow guide shell of a self-sinking and floating type section detection buoy comprises a locking device and an unhooking device. The locking device comprises a locking hook plate and a locking core plate; the locking hook plate is arranged on one half of the flow guide shell, and the locking core plate is fixed on the other half of the flow guide shell; a lock hook at the front end of the locking hook plate is matched and locked with a lock ring at the front end of the locking core plate; the unhooking device comprises a base and a buoyancy air bag; the base is arranged below the locking hook plate, and the buoyancy air bag is installed between the base and the locking hook plate. By means of changes of internal pressure and external pressure of the air bag at different water depth positions, the buoy can be smoothly laid in an area where a ship cannot reach easily, and the flow guide shell can be automatically disassembled and disengaged after laying is completed.

Description

technical field [0001] The invention belongs to the technical field of marine environment monitoring, and in particular relates to an automatic shedding device for a diversion shell of a self-sinking and floating profile detection buoy and a diversion shell. Background technique [0002] The self-sinking profiling buoy is a kind of ocean observation platform, which was first used in the international Argo project, so it is also called Argo buoy, which is dedicated to the measurement of ocean subsurface temperature, salinity and depth profile. After the buoy is deployed, it will work in the sea for more than two years until the power supply is exhausted. The ocean observation data obtained through Argo is conducive to the prediction of climate and natural disasters, and helps to understand the internal change process of the ocean. [0003] Argo buoys at this stage are mostly deployed by ships, and the deployment area is limited. It is difficult to deploy in areas that are di...

Problems solved by technology

[0005]In order to solve the technical problem that the diversion shell of the self-sinking and floating profile detection buoy cannot be automatically dropped off at the present stage, a device for automatically falling off the diversion shell of the self-sinking and floating profile detection buoy is provided , the device activates the automatic shedding device on the diversion shell of the buoy to open the lock hook through the change of the pressure inside and outside the airbag, so that the diversion shell disintegrates and falls off
