Abstract
A combined material conveyor and electrical generation system is disclosed. The invention may be used to provide electrical energy to a remote location through which the material conveyor passes and/or harness energy which would normally be dissipated in braking a material conveyor. One or more electrical generators is driven by the motion of a belt in a material conveyor. Electrical power generated by the generator is delivered to an external power output. The invention can capture the potential energy of particulate matter which is transported on a material conveyor, particularly through a net elevation drop. Electricity produced may be used immediately or stored in a battery system for future use.
Claims5
A combined material conveyor and electrical generator comprising:
- a) an elongated conveyor belt having an input end and an output end, said input end at a higher elevation than said output end and said conveyor belt supported along its length by a plurality of spaced apart transverse rollers;
- b) at least one electrical power generator for producing electrical power, each generator having an electrical power output and driven by motion of said conveyor belt;
- c) electrical conductors extending from each of said generators for electrically connecting said electrical power outputs to a power outlet for providing electrical power to electrical devices external to said material conveyor;
- d) a plurality of drive rollers in frictional rolling engagement with a surface of said conveyor belt wherein each of said generators has a drive shaft coupled for rotation with one or more of said drive rollers;
- and
- e) said generators being mounted inside said drive rollers and said drive rollers comprise a stationary end cap and a rotatable generally cylindrical shell mounted to said stationary end cap, wherein said electrical conductors for carrying electrical current generated by each of said generators extends through said stationary end cap.
A combined material conveyor and electrical generator comprising:
- a) an elongated conveyor belt having an input end and an output end, said input end at a higher elevation than said output end and said conveyor belt supported along its length by a plurality of spaced apart transverse rollers;
- b) at least one electrical power generator for producing electrical power, each generator having an electrical power output and driven by motion of said conveyor belt;
- c) electrical conductors extending from each of said generators for electrically connecting said electrical power outputs to a power outlet for providing electrical power to electrical devices external to said material conveyor and said power outlet being capable of providing more electrical power than the electrical power produced by any one of said generators;
- d) a plurality of drive rollers in frictional rolling engagement with a surface of said conveyor belt wherein each of said generators has a drive shaft coupled for rotation with one or more of said drive rollers;
- and
- e) said drive rollers underlie and support said conveyor belt and comprise outwardly extending shafts which turn with said drive rollers and said drive shafts of said generators are coupled by mechanical couplings to said outwardly extending shafts and turn as said outwardly extending shafts turn, and each of said drive rollers comprises a flange outwardly adjacent an edge of said conveyor belt for maintaining alignment of said conveyor belt with said rollers.
