In this embodiment, the adjacent objects are an upper well cover and a lower well cover which are adjacent to each other, and the relative displacement monitoring device comprises a fixing device 3, an elastic connecting device 4 and an induction device 5 which are fixedly connected together in sequence, and further comprises a control module 6 fixed on the lower surface of the lower well cover;

one end of the fixing device 3 is fixed on the lower well lid 2, and the other end of the fixing device is provided with a bent part 3-1; the control module 6 is fixed on the lower surface of the lower well cover 2.

The elastic connecting device 4 is a spring, one end of the elastic connecting device is fixedly connected with one end of the fixing device 3 provided with a bending part 3-1, the other end of the elastic connecting device is fixedly connected with the sensing device 5, and the elastic connecting device 4 and the sensing device 5 are positioned between the upper well cover 1 and the lower well cover 2;

a gyroscope, an accelerometer and an inclination angle sensor are arranged in the sensing device 5, and can sense whether the upper well cover and the lower well cover have displacement, inclination and other events which are relatively far away from or relatively close to each other;

The fixing device is rotatably fixed on the lower well cover, as shown in fig. 1, the fixing device is rod-shaped and is fixed in a hole of the lower well cover, the rod-shaped fixing device can rotate in the hole, and therefore when structures such as reinforcing ribs shown in fig. 2 and fig. 3 exist at the bottom of the upper well cover, the whole sensing device 5 is guided to rotate in a universal direction to avoid, and the sensing device 5 is prevented from being subjected to overlarge extrusion force.
