Abstract
The present invention discloses an embedded scraper rotation angle detection device for a scraper conveyor and a detection method. The detection device includes two extensible detection devices, two signal detection units and a remote processing unit. The two extensible detection devices and the two signal detection units are disposed at two ends of a scraper respectively. The signal detection units detect movement displacements of the extensible detection devices in real time and send out signals through wireless transmission modules, the wireless transmission modules and a wireless receiving module are used for data transmission, and a signal display processing module is used to calculate a rotation angle value of the scraper in real time, output and display the rotation angle value simultaneously, compare the rotation angle value measured in real time with a set safety threshold, and send out an alarm indication when the rotation angle value exceeds the safety threshold.
