An underwater glider energy system and its control method

Abstract

The invention discloses an underground glider energy source system and a control method thereof. The energy source system mainly comprises a proton exchange membrane fuel cell, a supercapacitor and a temperature difference thermomotor; the proton exchange membrane fuel cell provides continuous power to small-power continuous loading of an underground glider, and excess electric energy of the proton exchange membrane fuel cell is stored in the supercapacitor through a switch P; the supercapacitor uses the stored electric energy to provide power to large-power intermittent loading of the underground glider through a switch Q; and generating residual heat of the proton exchange membrane fuel cell and cold sea water work jointly to drive the temperature different thermomotor and further drives the underground glider to glide. The energy source system not only provides compact and efficient electric source for electric loading of the underground glider, but also provides excellent heat source for the temperature difference thermomotor, so that the underground glider has the operation capacity with all seawater, low energy consumption and long voyage.

Description

technical field [0001] The invention relates to an underwater glider, in particular to an energy system for an underwater glider. Background technique [0002] Under the action of positive or negative net buoyancy, the underwater glider rises or sinks in seawater by changing its own net buoyancy; at the same time, it produces horizontal motion due to the controllable pitch-attitude wings. As a result, the underwater glider produces a zigzag gliding motion in the depth profile of the ocean. [0003] Due to the buoyancy drive, the underwater glider has the advantages of low energy consumption and long range, and has a good application prospect in the field of marine environment monitoring. [0004] According to different driving energy acquisition methods, underwater glider is generally divided into electric energy driven underwater glider and temperature difference energy driven underwater glider. The temperature difference can drive the underwater glider, and the ocean tem...

AI Technical Summary

Problems solved by technology

However, limited by the quality of ocean temperature difference and the instability of ocean heat sources, the temperature difference can drive underwater glider and cannot work in the whole sea area.

In addition, during the voyage of the underwater glider, it is necessary to switch between diving and floating operations intermittently, resulting in large changes in the power of the electrical load, showing low average value and pulse fluctuation characteristics, and it is necessary to use a higher power power supply; The volume, weight and gliding resistance of the glider increase, thereby deteriorating the performance of the underwater glider
