Nuclear and biochemical protecting square cabin for sea and land uses

Abstract

The invention provides a nuclear and biochemical protecting square cabin for sea and land uses, comprising a cabin body. The cabin body is divided into a working area, an airlock room and a gas filtration and ventilation area, wherein the working area is connected with the airlock room and the gas filtration and ventilation area, respectively; the working area and the airlock room are enclosed by airtight walls; a gas filtration and ventilation device is arranged in the gas filtration and ventilation area, and a military overhead air-conditioner is arranged outside the gas filtration and ventilation area; the airlock room comprises a first airtight door, a second airtight door, a first pressure discharge valve and a second pressure discharge valve; and a pressure gradient is formed between the airlock room and the working area through the first pressure discharge valve and the second pressure discharge valve. With the adoption of the nuclear and biochemical protecting square cabin for sea and land uses, a higher and stable hyperpressure value in the cabin can be quickly created, so that rescuers can quickly and safely carry out various works in the cabin without using individual protective equipment.

Description

[0001] technical field [0002] The invention relates to the field of military equipment, in particular to a dual-purpose nuclear, biological and chemical protection shelter for land and sea. [0003] Background technique [0004] In the 21st century, the arms race among various countries has intensified, the international security situation is turbulent, the sale and purchase of nuclear materials in the international market, the popularization of biological and chemical preparation raw materials and research and development facilities, the more frequent nuclear, biological and chemical smuggling, and the increasingly rampant terrorism have all made nuclear, biological and chemical attacks more difficult. Possibilities are increasing day by day; with the development of the nuclear chemical industry and the expansion of the application fields of nuclear chemical products, in coastal areas where the global economy is developing rapidly, large-scale nuclear chemical facilities ...

AI Technical Summary

Problems solved by technology

[0005] At present, most of the nuclear, biological and chemical shelters that have been put into use in China have low overpressure values, and there is no obvious pressure gradient in each protection zone in the cabin. The environmental conditions of salt spray have led to the inability of the existing nuclear, biological and chemical shelters to provide a relatively safe and reliable workplace for the staff when carrying out reconnaissance, monitoring and emergency rescue at the site of nuclear, biological and chemical accidents; at the same time, the existing shelters The configured equipment cannot meet the environmental conditions of multiple working conditions, which limits the role played by nuclear, biological and chemical shelters in emergency accidents
