BUILT-IN SCRAPER TURNING ANGLE DETECTION DEVICE AND DETECTION METHOD FOR SCRAPER CONVEYOR

WIPO Patent Application WO/2020/258530

A1

A built-in scraper turning angle detection device and detection method for a scraper conveyor. The detection device comprises two sets of telescopic detection devices (3), two sets of signal detection units (5) and a remote processing unit (6). The telescopic detection devices (3) and the signal detection units (5) are respectively arranged at two ends of a scraper (1). The signal detection unit (5) detects in real time the movement and displacement of the telescopic detection device (3), and sends a signal via a wireless transmission module. The wireless transmission module and a wireless receiving module are used for data transmission. A signal display processing module is used for calculating in real time the turning angle value of the scraper (1), outputting the turning angle value for display, comparing the measured real-time turning angle value with a set safety threshold and giving an alarm indication when the safety threshold is exceeded.
