Slope deep displacement measuring device

The utility model relates to a slope deep displacement measuring device, which comprises a fixing device, a steel wire with a protective sleeve, a guide pulley, a base range pole, a box body, a sliding sensor, a sensor sensing rod, a fixing clip, a sliding support, an automatic telescopic rail, a leveling bracket, a fixing bracket, a traction weight and a wireless transmission device. The slope deep displacement measuring device does not need to inject slurry into a hole or install a protective tube because of adoption of a slope rock mass and traction weight bi-directional traction sliding device, and the base range pole is installed on an opening stabilizing base rock, thereby being capable of realizing measurement of the absolute displacement and the relative displacement of a deep part of a slope. The slope deep displacement measuring device is great in measuring span, high in precision, convenient to install, low in cost, and capable of being recycled and adapting to various geological conditions, and transmits displacement data of each measurement point at the deep part of the slope to a slope monitoring and processing center through the wireless transmission device.
