The rotating shaft is sleeved in the moving member 55. The outer side of the rotating shaft is provided with a first thread, and the inner side of the moving member 55 is provided with a second thread engaged with the first thread. When the rotating shaft rotates, the moving member 55 can move relative to the support leg 25 under the cooperation of the first thread and the second thread. After the manual excavation foundation emergency device is in the second state, the positioning module monitors the distance between the bottom side of each support assembly 15 and the ground, and according to the monitoring result, the control module starts the second motor 51, the second driving member 52 drives the second driven member 53 to rotate, the second driven member 53 drives the moving member 55 to move relative to the support leg, so that the bottom of the moving member 55 is supported on the ground, ensuring that the base assembly 1 is in a horizontal position, thereby ensuring the safety of the personnel.

Preferably, the connecting piece 33 is an iron chain. In the process of converting the artificial excavation foundation emergency refuge device from the first state to the second state, the connecting piece 33 moves in the through slot 321. When the lower end of the support column 216 abuts against the inclined surface 1321 of the protrusion 1132, the support column on the third side plate 213 lifts up the first top plate 31, and the support column on the fourth side plate 214 lifts up the second top plate 32, so that the first top plate 31 and the second top plate 32 are in an inclined state, thereby preventing the falling objects from piling up on the top plate assembly 3.

[0040] When the monitoring module detects an emergency situation, the control module starts the driving assembly 10, the first motor 101 drives the first driving piece 102 to rotate, the first driving piece 102 drives the first driven piece 103 to rotate, the first driven piece 103 drives the first moving seat 12 and the second moving seat 13 to move away from each other, so that the artificial excavation foundation emergency refuge device is in an unfolded state. The monitoring module detects the distance between the bottom side of each support assembly 15 and the ground, according to the monitoring result, the control module starts the second motor 51, the second driving piece 52 drives the second driven piece 53 to rotate, the second driven piece 53 drives the moving piece 55 to move relative to the support leg, so that the bottom of the moving piece 55 is supported on the ground, ensuring that the base assembly 1 is in a horizontal position, thereby ensuring the safety of the personnel; at the same time, the side plate assembly 2 also converts from the folded state to the unfolded state, with the third side plate 213 and the fourth side plate 214 rotating outward, the lower end of the support column 216 can abut against the protrusion 1132 of the third mounting seat 113, the support column on the third side plate 213 lifts up the first top plate 31, and the support column on the fourth side plate 214 lifts up the second top plate 32, so that the first top plate 31 and the second top plate 32 are in an inclined state, thereby preventing the falling objects from piling up on the top plate assembly 3. The operator can enter the artificial excavation foundation emergency refuge device to hide and take refuge, and enough rescue time is reserved for the personnel.
