Abstract
A device for enabling autonomous powering of a monitoring node of a scraper conveyor chain includes a bottom baffle, a friction wheel drive device, a limiting device, a generator, an energy storage battery, a cable entry device, and dampers. The bottom baffle is connected to a bottom portion of a scraper of a scraper conveyor. The friction wheel drive device comprises a ball, a friction wheel, a drive shaft connected to the generator, and a shaft coupler. The friction wheel is disposed on the drive shaft, and an outer edge of the friction wheel is in contact with a surface of the ball. The limiting device is a ball housing that is connected to the bottom baffle, and is used for limiting the ball within the ball housing. The energy storage battery is connected to the generator, and is used to store electrical energy generated from the generator. The dampers are disposed on the drive shaft.
