[0055] The working principle of this utility model:

[0056] Before using the utility model, the device is first carried to the working position by a drone or other means, and then its fall is controlled at an appropriate height. When falling to the ground, the limit cone is first inserted into the ground to ensure its stability. Then, the impact of the fall is buffered by the pull rope 3 and the spring on the narrowband communicator 2. At the same time, the springs in the cavities of the side panels 2 13 and 3 14 are compressed downward, so that the vertical protrusion 141 in the side panel 3 14 is separated from the top panel 15. At this time, under the elastic force of the elastic protrusion 142 on the top panel 15, the top panel 15 When the grooved protrusion 151 moves upward, the movable cone 132 of the second side plate 13 is pressed to move toward the adjacent support block 131, so that the movable cone 132 is separated from the protrusion with the groove of the top plate 15. Then, under the action of the elastic block at the level of the third side plate 14, the top plate 15, the first side plate 12, the second side plate 13, and the third side plate 14 are unfolded. At this time, the device enters the working state. After all the work of the device is completed, the motors at the bottom of the first side plate 12, the second side plate 13, and the third side plate 14 work to control their reset so as to recover them.

[0057] When the narrowband communicator 2 is vibrated by external force, the horizontal vibration is buffered by the elastic deformation of the pull rope 3 around the narrowband communicator 2, while the vertical vibration is stabilized by the spring at the bottom of the narrowband communicator 2 to ensure the stable working state of the device.
