Abstract

An under water self-holding sectional buoy with combined energy source is composed of external bag, internal bag, electromagnetic valve, hydraulic plunger pump, proton exchange membrane fuel cell (PEMFC), DC servo motor, casing, and a sealed cvity consisting of sealing bottom plate, working chamber of heat machine, cooling chamber of heat machine, cooling chamber of PEMFC, and bossing. The combined thermal and electric supply system of PEMFC is used for the temp difference drive in deep sea and electric drive in shallow sea.

Description

technical field [0001] The invention relates to an instrument for measuring water area profile parameters, in particular to a novel self-sustaining underwater profile buoy using a combined heat and power system of a proton exchange membrane fuel cell as a comprehensive power source. Background technique [0002] The self-sustaining underwater profiling buoy is a new type of underwater monitoring equipment that performs profile movement by changing its own buoyancy. It can carry various sensors for large-scale and long-term marine parameter measurement, and can regularly send the obtained data back to the base station through satellites, so it has become an important tool for marine environment monitoring. At present, a variety of self-sustaining underwater profiling buoys have been successfully developed abroad, such as the self-sustaining Lagrangian automatic circulation profiling buoy ALACE jointly developed and developed by Webb Research, Falmoth Scientific Company of the...
