The sensor support 4 is balanced only when the two ends P1, P2 of the sling 21 and the two contact points P3, P4 of the sling 21 with the mobile pulley 44 are in one plane due to the effect of gravity. When the hanging strip 21 is rotated on the ground, if the hanging strips P1, P2, P3 and P4 are not located in a plane, under the action of gravity, the horizontal forces F1 and F2 perpendicular to the connecting line of the P3 and P4 are respectively received by the P3 and P4, and under the action of torque formed by the horizontal forces F1 and F2, the sensor support 4 rotates. Due to inertia, the sensor support 4 will rotate back and forth in the equilibrium position, and due to the presence of the slings 21 and mud damping, the energy will gradually dissipate, and P1, P2, P3, P4 will eventually lie in a new plane.
