Multipurpose blower assembly

A multipurpose blower assembly for attachment to a supportive structure located adjacent to a water body, said multipurpose blower assembly comprising, in combination:

• an upper assembly being configured to reside above the water body's surface and having a top plate and an electrical gear motor mounted atop thereof, said electrical gear motor having an output shaft;
• a rotating shaft having a first end coupled to said output shaft of the electrical gear motor and a second end;
• a lower assembly being configured to reside below the water body's surface and having a blower motor, an upper bracket attached to said second end of the rotating shaft and a lower bracket pivotally connected to said upper bracket, said lower bracket having a motor support plate for mounting said blower motor, said upper bracket and said lower bracket each having a semi-radial pattern of apertures, said upper bracket and said lower bracket each having an aperture from the semi-radial pattern of apertures in alignment with one another to receive a bolt and nut assembly;
• a mount post having an upper end attached to said top plate and a lower end attached to a mid-support plate, said mid-support plate having an aperture extending therethrough for passing a select portion of the rotating shaft;
• a system controller having a microcontroller configured with a central processing unit, a program memory module for receiving and storing a programmable instruction set capable of controlling operation of said electrical gear motor, a non-volatile memory module for storing user operator inputs, and a volatile memory module for storing temporary data generated and processed by the central processing unit;
• a manual interface panel communicatively coupled to said microcontroller and having a setup key operating conjunctively with a clockwise key and a counterclockwise key for setting a clockwise endpoint position and a counterclockwise endpoint position of said output shaft for storage into said non-volatile memory module;
• and
• an H-bridge circuit communicatively coupled to said microcontroller, said programmable instruction set having executable instructions for activating said H-bridge circuit to supply power to said electrical gear motor and effect interchanging clockwise and counterclockwise rotation of said output shaft after respectively reaching said counterclockwise and clockwise endpoint positions, said H-bridge circuit having a motor feedback loop for monitoring operative conditions of said electrical gear motor.
