Design and Experiment of Deep-sea Energy-storage Buoyancy Regulating System

摘要

An energy-storage buoyancy regulating system is proposed in order to help underwater robot to float upward and dive downward vertically with low energy consumption. Firstly, principle analysis and system design of underwater buoyancy regulating system are carried out based on the principle of accumulator. After that, we analyze the special performance requirements for system components in deep-sea operating environment, carry out model selection and reliability analysis for main system components (accumulator and hydraulic pump) and build the experimental prototype. Finally, based on the experimental prototype that has been built and under the circumstance of simulating the deep-sea pressure, we carry out function and performance experiment of the system according to the experimental method and procedure that have been designed in advance. The results of pressure experiment indicate that the energy-storage buoyancy regulating system can meet the requirements of anticipated performance index.
