Sensitization device, vibration monitoring system comprising sensitization device and coal mine belt conveyor

The invention relates to a sensitization device, a vibration monitoring system comprising the sensitization device and a coal mine belt conveyor. The sensibilization device comprises a protection shell, the protection shell and a vibration measurement object can form a protection cavity in a surrounding mode, and the vibration measurement object is located on the side face of the protection cavity. The vibration monitoring system further comprises a cantilever beam, the cantilever beam is installed in the protection cavity, the first end of the cantilever beam is a fixed end fixed to the vibration measurement object, the second end of the cantilever beam is a free end suspended in the protection cavity, and the free end is used for holding a sensing optical cable of the vibration monitoring system. Through the arrangement, the vibration signal can be amplified, the sensitivity of the vibration monitoring system is improved, the vibration monitoring system can capture an abnormal vibration signal in time, and
