Early warning device for preventing pole from falling and inclining

The utility model discloses an anti-toppling tilting early warning device, which comprises an SMA seat, a mercury switch, a 4G communication module, a PCB substrate, a power interface, a motion sensor, a single chip microcomputer and a clamping rod seat, and is characterized in that the SMA seat, the mercury switch, the 4G communication module, the power interface, the motion sensor and the single chip microcomputer are soldered on the surface of the PCB substrate to form the early warning device. According to the utility model, the early warning device for serving the concrete pole is arranged outside the concrete pole, the sensor is arranged in the early warning device to detect the attitude angle, namely the gradient, of the concrete pole, and when the gradient reaches a set threshold value, early warning information is sent to operation and maintenance personnel to inform responsible personnel to go to the current concrete pole to check the condition; the concrete pole is overhauled in time, and the incli
