Well lid monitoring device capable of detecting fragmentation degree of well lid

The invention discloses a manhole cover monitoring device capable of detecting the fragmentation degree of a manhole cover, and the device comprises a detector housing, a detection probe disposed at the lower end of the detector housing, and a detector cover plate and a light sensor which are disposed at the upper end of the detector housing in an attached manner, and the light sensor is disposed at the upper end of the detection probe. And the light sensor is mounted at the bottom of the detector shell. According to the manhole cover monitoring device capable of detecting the fragmentation degree of the manhole cover, through arrangement of the detection probe and the light sensor, whether the manhole cover is fragmented or not can be detected according to the intensity of light, and in combination with arrangement of the temperature sensor and the humidity sensor, the underground temperature and humidity can be detected; and the detector can be conveniently installed and fixed at the lower end of the well l
