AI Technical Summary

Technical Problem

The existing geological disaster rescue equipment cannot accurately locate the mouth and nose of buried people, cannot continuously replenish oxygen in the space near their noses, nor can they directly replenish the mouths of buried people and replenish fluid food, resulting in a low survival rate.

Method used

A deep gas detection personnel search and rescue device is designed, including a gas transmission hose and a fluid replenishment hose arranged in parallel. The front end is equipped with a lighting lamp, a wired intercom and a camera. The odor collection hose and gas composition analysis device are used to accurately locate the buried person's position, and oxygen and water are replenished through the gas transmission hose and a fluid replenishment hose.

Benefits of technology

It can accurately locate the mouth and nose of buried people, prevent coma caused by hypoxia and water deficiency, and improve survival rates, especially in earthquakes, landslides, and mudslide disasters.

Abstract

The deep gas detector search and rescue device comprises a gas conveying hose and a liquid supplementing hose which are arranged in parallel, a gas outlet of the gas conveying hose is located behind a liquid outlet of the liquid supplementing hose, and a plurality of smell collecting hoses are arranged on the outer side wall of the gas conveying hose and / or the liquid supplementing hose in parallel. A gas outlet of each smell collection hose is communicated with a gas inlet of the gas component analysis device; and a liquid inlet of the liquid supplementing hose is respectively communicated with a liquid outlet of the drinking water conveying pipe and a liquid outlet of the nutrient solution conveying pipe. The purpose of the invention is to provide a device for continuously supplying oxygen to the space near the nose of a buried person to prevent the buried person from coma and death due to oxygen deficit, and directly supplying water and fluid food to the mouth of the buried person to prevent the buried person from coma and death due to lack of water and nutrient food. And the survival rate of trapped and buried people in earthquake, landslide and debris flow disasters is greatly improved.
