Manhole cover loss monitoring device
The invention provides a manhole cover loss monitoring device comprising a bracket, a rotating shaft, a connecting rod, an angle sensor, and a wireless communication module. The bracket is fixed to the wall of a manhole. One end of the rotating shaft is rotationally connected with the bracket, and the other end is vertically fixed to the connecting rod. Under the action of gravity, the connecting rod and the rotating shaft rotate about the axis together. When a manhole cover is not removed, one end of the connecting rod bears against the manhole cover; and when the manhole cover is removed, one end of the connecting rod bounces. The angle sensor is fixed to the connecting rod, and is used to monitor the angle of rotation of the connecting rod and send a warning signal to a remote server through the wireless communication module when monitoring that the angle of rotation of the connecting rod changes. Removal of a manhole cover can be monitored in time, and maintenance personnel can be reminded to carry out inspection and maintenance in time, thus preventing the occurrence of accidents.
