Carbon dioxide detection apparatus and detection method used for life detection in ruins

Abstract

The invention provides a carbon dioxide detection apparatus and detection method used for life detection in ruins. In the apparatus, a sampling rod sleeve is of a hollow cylindrical structure, a conical head is fixed at a front of an internal support to compose a sampling inner core, and the rear end of a conical sleeve and the front end of the sampling rod sleeve is in sealing connection to form a hollow sampling rod; the sampling inner core is inserted into the sampling rod and arranged to be slidable, and a locking device is mounted on the sampling inner core; a gas sampling pump, a carbon dioxide sensor and a separator plate are fixed on the internal support, the separator plate isolates the gas sampling pump from the carbon dioxide sensor, the separator plate and the inner wall of the sampling rod are in sliding hermetic seal, and an outlet air pipe of the gas sampling pump penetrates the separator plate to communicate with the carbon dioxide sensor; and the carbon dioxide sensor is electrically connected with a display control alarm device. With the detection apparatus and detection method provided by the invention, the problem that a conventional carbon dioxide life detection apparatus is not applicable to detection in an environment of rubbles is overcome, and searching of people who are trapped in rubbles in a rescue scene is facilitated.

Description

technical field [0001] The invention relates to the technical field of disaster relief and search equipment, in particular to a carbon dioxide detection device and detection method for life detection in ruins. Background technique [0002] Searching for trapped persons in the ruins by means of carbon dioxide concentration detection is one of the ruin instrument search methods. At present, there is no production of a carbon dioxide concentration detection device specially used for searching for victims trapped in ruins in China. Relevant instruments have been produced abroad, but most of them are not suitable for use in the environment of rubble and ruins, or do not have the function of preventing rubble and debris, so that their application to the search of people trapped in ruins is limited. For example, CO2 life detection devices such as GE in the United States and M9W-CDE in the United Kingdom are mainly used for the detection of stable and confined spaces such as contai...

Problems solved by technology

Before using it in the ruins, you need to create a channel. Inserting it directly into the ruins may cause airway blockage

In addition, the existing carbon dioxide life detection devices usually place the carbon dioxide sensor in the special instrument box outside the sampling rod, and use the gas pipeline and sampling pump to transmit the gas at the front end to the instrument box. In this way, the measured gas needs to pass through a long The gas pipeline has problems such as slow response speed, large demand for sample gas, and inaccurate measurement results if the gas pipeline is not well sealed.
