Title:
BELT STATE MONITORING APPARATUS AND METHOD FOR SELF-POWERED BELT CONVEYOR
Document Type and Number:
WIPO Patent Application WO/2021/233393
Kind Code:
A1
Abstract:
A belt state monitoring apparatus and method for a self-powered belt conveyor, comprising: an impact power generation sensor (2) mounted on a cushioning support roller (1), and a rotation power generation sensor (4) and a weighing sensor (5) which are mounted on a conventional support roller (3); the impact power generation sensor (2), the rotation power generation sensor (4), the weighing sensor (5), a signal acquiring and processing unit, a central processing unit, a database, and an interaction unit are electrically connected; the impact power generation sensor (2) and the rotation power generation sensor (4) are electrically connected to a confluence power supply unit. An apparatus capable of generating information and generating power is formed by using a blanking impact and rotation of belt support rollers, and achieves two functions of belt surface state detection and material flowrate measurement. Under a belt load condition, a material flow volume is measured in real time, real-time acquisition of material flow information is achieved, and under a belt no-load condition, a belt surface video is acquired in real time for monitoring.
