Abstract:
1. A rechargeable snow removal device for displacing snow from a variety of locations, said rechargeable snow removal device comprises: a frame; a primary snow intake section connected to said frame; a power-actuated vacuum mechanism connected to said primary snow intake section for siphoning snow into said primary snow intake section; an exhaust nozzle in fluid communication with said vacuum mechanism for discharging snow along a scattered path away from said frame; a first power source selectively coupled to said vacuum mechanism; a second power source selectively coupled to said vacuum mechanism; means for automatically directing power from said second power source to said vacuum mechanism and immediately thereafter interrupting power from said first power source to said vacuum mechanism so that said vacuum mechanism continuously receives power from at least one of said first and second power sources and thereby remains at an active operating mode when one of said first and second power sources runs out of power; an auxiliary snow intake section coupled to said vacuum mechanism and spaced from said primary snow intake section, said auxiliary snow intake section for channeling snow upstream to said vacuum mechanism and out from said exhaust nozzle; wherein said automatic power directing and interrupting means comprises: a user interface; a power selection and distribution interface electrically coupled directly to said user interface and said vacuum mechanism as well as said first and second power sources respectively; wherein said user interface generates and transmits a plurality of input signals upon receiving a plurality of respective user inputs for permitting said power selection and distribution interface to communicate with said vacuum mechanism when said rechargeable snow removing device is at an operating mode; wherein said power selection and distribution interface comprises: a first sensor electrically coupled directly to said first power source; and a second sensor electrically coupled directly to said second power source; and wherein said first and second sensors generate and transmit first and second power status signals associated with corresponding power levels remaining in said first and second power sources respectively; wherein each of said first and second power status signals are true when said first and second power sources have at least a minimum quantity of power stored therein respectively; wherein each of said first and second power status signals are false when said first and second power sources do not have at least the minimum quantity of power stored therein respectively; wherein the minimum quantity of power is equal to a minimum requisite voltage level to operate said vacuum mechanism.
