Problems solved by technology

[0010] The Chinese patent with the patent number CN1543001A provides a magnesium seawater battery. This battery uses seawater as the electrolyte and uses dissolved oxygen in seawater as the cathode depolarizer. Although the battery has a simple structure, its cathode efficiency is very low. Moreover, the working current density is small and the cathode area is large, which also limits its application range, and is not suitable for some electrical equipment that requires high power, such as underwater power supplies.

Abstract

The invention relates to an oxygen automatic supply control device of a subaqueous metal-oxygen cell system, comprising an oxygen storage device and an automatic regulating device for oxygen capacity, wherein the automatic regulating device for the oxygen capacity comprises a gas storage cabin, an air bag or air cylinder, a solenoid valve and a control switch or a sensor; the gas storage cabin and the air bag or air cylinder are connected with the oxygen storage device by a gas pipeline; the solenoid valve is arranged on a connection pipeline; the control switch or sensor is arranged in the air bag or air cylinder; the gas storage cabin and the air bag or the air cylinder are connected with a cathode oxygen chamber of the metal-oxygen cell system by the gas pipeline; the control switch iselectrically connected with the solenoid valve by guide lines; and the output signals of the sensor are processed by a controller and then the controller is electrically connected with the solenoid valve by the guide lines. The subaqueous oxygen automatic supply control device is used for solving the oxygen supply problem of the subaqueous metal-oxygen cell system so as to realize automatic oxygen supply, and solving the problem of gas-liquid pressure dynamic balance at two sides of an oxygen cathode when the metal-oxygen cell system is taken as a subaqueous power supply.

Description

technical field [0001] The invention relates to an underwater power supply system, in particular to an underwater metal-oxygen battery system, specifically an oxygen automatic supply control device for the metal-oxygen battery system. Background technique [0002] In recent years, with the advancement of science and technology, people's understanding of marine resources has been further improved, and marine engineering technology has also made great progress. Marine development has increasingly become an important strategic plan for many countries. Marine remote sensing technology, marine navigation technology, deep-sea detection technology, and marine military technology are all inseparable from power supplies. Due to the particularity and complexity of the actual working conditions under the sea, the current conventional primary batteries and secondary batteries (such as lead-acid batteries, nickel-metal hydride batteries, silver-zinc batteries, lithium-ion batteries, etc....
