Abstract

The invention relates to a fastening device of a multiple information life detecting system for a mine drilling rescue. The fastening device comprises an inner ring and an outer ring. The inner ring comprises an inner ring wall; at least one L-shaped lock catch opening is formed in the inner ring wall; the outer ring comprises an outer ring wall; lock latches which is as many as the L-shaped lock catch openings are arranged on the inner side of the outer ring wall; the inner diameter of the outer ring is larger than the outer diameter of the inner ring and the outer ring. A high security and strong applicability fastening device of the multiple information life detecting system for the mine drilling rescue is provided.

Description

technical field [0001] The invention relates to the improvement of drilling rescue and communication equipment, especially for the detector part in the multi-information life detection system of mine drilling rescue. Background technique [0002] After a mine accident, especially in the initial stage, there are often people who survive and are trapped in certain areas of the mine. They urgently need to be quickly searched and located, and provided with ventilation, oxygen and food supplies, so that they can be rescued from the disaster area as soon as possible. However, due to the complexity of the post-disaster underground environment, the uncertainty and high risk of the disaster, coupled with the limitations of rescue technology and equipment, underground rescue is often unable to be carried out or the progress is slow, which eventually leads to the loss of life of the trapped people. Using the multi-information life detection system for drilling rescue can search for the...
