Bionic gill type underwater breathing equipment

Abstract

The invention discloses bionic gill type underwater breathing equipment. The bionic gill type underwater breathing equipment comprises a breathing device, a carbon dioxide filtering device, an oxygenpreparation device, a gas mixing device, an air compressor, an air storage bottle and a control system, wherein the oxygen preparation device is connected with the gas mixing device and is used for supply oxygen to the gas mixing device; the air compressor is used for compressing mixed gas from the gas mixing device and conveying compressed gas to the air storage bottle; an oxygen concentration sensor is arranged on the carbon dioxide filtering device or on a gas conveying pipeline between the carbon dioxide filtering device and the gas mixing device; and the control system is used for controlling the compression amount of the air compressor to the mixed gas and controlling oxygen production amount and oxygen conveying amount according to an oxygen concentration signal transmitted by the oxygen concentration sensor. The bionic gill type underwater breathing equipment is high in oxygen production rate and gas utilization rate, and leaking bubbles are not produced when the equipment is used by a user, so that the interference caused by marine organisms is avoided; and by utilizing the equipment, long-term underwater work can be realized.

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
