A bionic fish gill type underwater breathing equipment

Abstract

The invention discloses a bionic gill type underwater breathing equipment, comprising a respirator, a carbon dioxide filtering device, an oxygen preparation device, a gas mixing device, an air compressor, an air storage bottle and a control system, an oxygen preparation device and a gas mixing device Connected and supply oxygen to the gas mixing device, the air compressor is used to compress the mixed gas from the gas mixing device and deliver the compressed gas to the air storage bottle, on the carbon dioxide filter device or between the carbon dioxide filter device and the gas mixing device An oxygen concentration sensor is installed on the gas delivery pipeline, and the control system is used to control the compression amount of the mixed gas by the air compressor and control the oxygen production and delivery volume according to the oxygen concentration signal transmitted by the oxygen concentration sensor. The invention has high oxygen production rate and high gas utilization rate, no leaking air bubbles will be generated when the user uses the equipment, and interference to marine organisms is avoided, and long-time underwater operations can be realized by using the invention.

Description

technical field [0001] The invention belongs to the technical field of underwater breathing apparatus, in particular to a bionic gill type underwater breathing apparatus. Background technique [0002] The earth is a planet of water, and oceans account for 71% of the world's total area, and there are abundant resources in the oceans. With the development of science and technology and the progress of society, human beings also realize that the ocean has abundant resources and great strategic significance. However, due to various reasons, human beings have not been able to explore and work in the sea for a long time like fish. In recent years, with the synthesis and preparation of new material membranes, the technology of filtering oxygen from seawater has been realized, so some types of underwater respirators have appeared, but these underwater respirators have shortcomings and infeasibility: first, human breathing What the circulatory system depends on is not the oxygen cont...

Problems solved by technology

In recent years, with the synthesis and preparation of new material membranes, the technology of filtering oxygen from seawater has been realized, so some types of underwater respirators have appeared, but these underwater respirators have shortcomings and infeasibility: first, human breathing What the circulatory system depends on is not the oxygen content, but the oxygen partial pressure. The oxygen partial pressure in the atmosphere is 0.2bar, while the previously designed underwater rebreather only produces oxygen, and does not produce breathing with a certain pressure and a sufficient amount of inert gas. Under such conditions, people cannot breathe normally; secondly, the oxygen content in the air inhaled by humans accounts for 21%, and the oxygen content in the air exhaled by humans accounts for 17%. It is unscientific and unreasonable to discharge precious oxygen and nitrogen into the water without recycling; finally, the air bubbles generated by exhalation will disturb the surrounding environment such as fish schools, which is not conducive to underwater operations
