5. The shock absorbing device as defined in claim 1, wherein the housing includes an upper protective tube and a lower protective tube, the upper protective tube being adapted to be sleeved in the steel sleeve, the lower protective tube being movable relative to the upper protective tube in an axial direction of the probe drill rod, the upper protective tube and the lower protective tube enclosing the instrumentation capsule when the housing is in the closed state, the upper protective tube and the lower protective tube being spaced apart in the axial direction of the probe drill rod when the housing is in the open state, and the probe assembly of the instrumentation capsule being located between the upper protective tube and the lower protective tube.

6. The damping device according to claim 5, wherein the upper protection tube is internally provided with at least one driving motor and an upper thrust bearing which are sleeved on the periphery of the mandrel, the upper thrust bearing is positioned between the first elastic piece and the second elastic piece, is fixedly connected with the first elastic piece and is connected with the inner wall of the upper protection tube, and the driving motor is in driving connection with the upper thrust bearing so as to drive the upper thrust bearing to rotate around the axis of the detection drill rod and drive the mandrel to rotate;

the lower protection pipe is internally provided with a lower thrust bearing, the lower thrust bearing is used for being sleeved on the periphery of the mandrel, is arranged at the lower end of the instrument cabin and is in threaded connection with the lower protection pipe, so that when the upper thrust bearing drives the mandrel to rotate, the lower thrust bearing is stressed by the mandrel to rotate and drive the lower protection pipe to move close to or away from the upper protection pipe.

7. The damping device according to claim 6, wherein the upper protection tube is in sliding oil seal connection with the mandrel, a sliding block and a limiting block are arranged in the upper protection tube, the sliding block is sleeved on the periphery of the driving motor and used for fixing the driving motor, the limiting block is arranged above the sliding block, and the sliding block can slide between the limiting block and the first elastic piece along the axial direction of the detection drill rod; and/or the number of the groups of groups,

the damping device further comprises a third damping component, the third damping component comprises a third elastic piece, one side, close to the drill bit, of the lower thrust bearing is connected with a connecting buffer piece, and the third elastic piece is fixedly connected to the lower side of the connecting buffer piece.

8. The shock absorbing device of claim 1, further comprising a first multi-stage seal ring sleeved on the periphery of the mandrel and positioned between the upper thrust bearing and the first elastic member; and/or the number of the groups of groups,

the damping device further comprises a second multistage sealing ring, wherein the second multistage sealing ring is sleeved on the periphery of the instrument cabin and is arranged on the upper side of the lower thrust bearing.

9. The shock absorbing device as defined in claim 1, wherein the outer periphery of the housing is provided with a wear sleeve.

10. A deep soil detecting apparatus, comprising:

the drill rods are sequentially connected in the up-down direction, and the drill rods comprise detection drill rods positioned at the bottom ends;

the instrument cabin is sleeved on the periphery of the detection drill rod and comprises a carrier and a detection assembly accommodated in the carrier;

the drill bit is arranged at the lower end of the detection drill rod; the method comprises the steps of,

a shock absorbing device as claimed in any one of claims 1 to 9.
