Geological disaster monitoring and early warning device

The utility model belongs to the technical field of geological disaster monitoring, and particularly relates to a geological disaster monitoring and early warning device. According to the technology, two vertically-arranged fixing piles are included, two first fixing pipes are horizontally arranged between the two fixing piles and located on the same horizontal line, fixing plates are fixed to the opposite ends of the two first fixing pipes, and an adjusting mechanism used for adjusting the distance between the two fixing plates is arranged between the two fixing plates; fixing rods are independently installed in the first fixing pipes in a penetrating mode, one ends of the fixing rods penetrate out of the first fixing pipes to be connected with the top ends of the corresponding fixing piles through connecting assemblies, and marking lines are arranged on the fixing rods located in the first fixing pipes. According to the design, the fixed pile moves to drive the fixed rod to move, so that the marking line on
