Regarding the intelligent idler technology of belt conveyor,the idler needs to meet the requirements for cooperative work of sensor power supply,data collection and data transceiver modules.The cost with long-distance lines for power supply is too high,and manual inspection is needed if batteries are selected.This greatly reduces the working efficiency of the sensor.Now,the power supply module needs to be built in the idler,so structure design of idler is needed.An intelligent idler was designed by combining the outer rotor permanent magnet generator with the idler.Mechanical energy was converted into electrical energy by rotating the idler to provide power for the sensor.The mechanical analysis of the designed intelligent idler was carried out.Compared with the ordinary idler,the intelligent idler can meet the working requirements of the ordinary idler under when materials are added onto the conveyor belt.Finally,the dynamic modal analysis was carried out,and the frequency modal frequency of the intelligent idler was obtained,which provides a basis for the structural design of the intelligent idler and reduces the failure of the transmission drum.
