One end of the positioning chain 6 is fixed to the top of the refuge cabin device and the other end is coiled on the top of the foundation pit. It is mainly used to search for buried refuge cabin devices. The positioning chip 7 and the alarm 8 are used to assist the search and rescue work, mainly for positioning and prompting. The satellite phone 9 is placed inside the refuge cabin device to facilitate the trapped personnel to maintain communication with the outside world, to keep abreast of the physical and mental conditions of the relevant personnel, and to guide emergency rescue work.

[0028] A connecting steel plate 10 is welded on the steel column 19 and is used to connect the refuge chamber device to the surrounding structure. The two are firmly fixed by welding or bolting to prevent the refuge chamber device from being washed away from its original position by collapsed soil.

[0029] The ventilation system is installed, and a ventilation hole 11 is reserved on the top of the cabin. One end of the ventilation hose assembly 12 is fixed on the cabin and extends into the ventilation hole 11 and is in close contact, while the other end can be placed on the top of the foundation pit. The ventilation hose assembly 12 is connected to the inner cavity of the cabin to the atmosphere to ensure air circulation inside the refuge cabin device. The ventilation hose assembly 12 is made of a steel-plastic hose.

[0030] The anti-collision system is installed, mainly composed of a standing safety belt 13 and a rubber plate 14. The rubber plates 14 on the upper, lower, front, rear, left and right sides of the cabin body, and the standing safety belts 13 on the front, rear, left and right sides of the cabin body. The standing safety belts 13 are fixed on the side walls inside the refuge cabin device according to the standard height, and the rubber plates 14 are fully spread inside the refuge cabin device to protect the personal safety of the people inside the refuge cabin device.
