The invention relates to a shaft-end overhung
piezoelectric cantilever beam
electric generator, and belongs to the technical field of
new energy resources and power generation. A left end cover and a right end cover are respectively installed at two ends of a shell body through screws. A semi-annular balancing weight is installed on the lower side of the interior of the shell body through a screw. The upper portion of the left end cover and the upper portion of the right end cover are respectively provided with a lightening hole. A
magnet I and a bearing are embedded in the inner side of the bottom wall of the left end cover. A
magnet I and a bearing are embedded in the inner side of bottom wall of the right end cover. A piezoelectric vibrator is arranged between the left end cover and the shell body in a compression joint mode. A piezoelectric vibrator is arranged between the right end cover and the shell body in a compression joint mode. A
magnet II and a frequency-modulation
mass block are installed at the free end of each piezoelectric vibrator. A rotating shaft of a rotor is installed on the left end cover and the right end cover through bearings. A connecting disc is installed at one end of the rotating shaft through a nut. A magnet III is embedded in a
rotating disc of the rotor. The shaft-end overhung
piezoelectric cantilever beam
electric generator has the advantages that the piezoelectric vibrators are motivated for electric generation and external fixing and supporting are not needed; the shaft-end overhung
piezoelectric cantilever beam
electric generator is an integrated type individual component, so that the structure of a rotating body does not need to be changed, and the shaft-end overhung piezoelectric
cantilever beam electric generator is convenient to install and maintain; the shaft-end overhung piezoelectric
cantilever beam electric generator is high in reliability, strong in power generation capacity, and wide in velocity zone.
