[0014] As described above, due to the adoption of the above technical solution, the beneficial effects of the present application are:

[0015] In the present application, the detection head can be protected from collision by the arrangement of the protective member. When the detection head is lowered into the well and shakes, the protective member first contacts the well wall. Specifically, when the first protective sub-plate contacts the well wall, it will squeeze the first elastic sheet to start deforming, and the contact force will not be transmitted to the detection head. When the second protective sub-plate contacts the well wall, it will squeeze the second elastic sheet to start deforming, and the contact force will not be transmitted to the detection head, ensuring that the detection head will not be subjected to collision and unable to operate before entering the water.
