Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:
Gather a piezoelectric generating device for wind energy, comprising: base 1, fixed head 2, fixed block 3, fan 4, rotating shaft 5, flywheel 6, short cylindrical 7, connecting rod 8, support 9, impact block 10, cantilever beam piezoelectric vibrators 11, stalloy 12, piezoelectric ceramic piece 13 and mass 14; Described fixed head 2, fixed block 3 are fixed on described base plate 1 with support 9; One end of described cantilever beam piezoelectric vibrators 11 is arranged between described fixed head 2 and the crack of fixed block 3, is fixed by screw in compression; Described cantilever beam piezoelectric vibrators 11 is multiple cantilever beam piezoelectric vibrators; Described fixed head 2 is provided with the hole perpendicular to plate face horizontal direction, and described rotating shaft 5 is arranged in hole, and described fan 4 is connected by described rotating shaft 5 both sides being arranged on described fixed head 3 with flywheel 6 respectively; Described short cylindrical 7 is fixed on described flywheel 6; Described connecting rod 8 connects described short cylindrical 7 and impact block 10 respectively, and described connecting rod 8 can rotate around described short cylindrical 7; Described impact block 10 is arranged on described support 9, and support 9 can carry out certain spacing to impact block 10; The tail end of described impact block 10 is designed to crossbeam and is against in described cantilever beam piezoelectric vibrators 11, and the span of crossbeam can just collide all cantilever beam piezoelectric vibrators 11.Bearing is provided with between described rotating shaft 5 and the hole of described fixed head 2; The two ends of rotating shaft 5 are provided with flat key, and flat key connects described fan 4 and flywheel 6 respectively, and fan 4 and flywheel 6 are all fixed in rotating shaft 5 by nut; Flat key connects can determine that rotating shaft 5 rotation can drive fan 4 and flywheel 6 to rotate.Described support 9 is provided with rectangular indentation, the two side of rectangular indentation is equipped with the rectangular channel of horizontal direction.On the relatively described support 9 of described impact block 10, the position of rectangular channel is provided with rectangle platform, and rectangle platform can slide on described rectangular channel.One end of described impact block 10 is provided with fixture block, and one end of described connecting rod 8 is arranged between fixture block, and fixture block and connecting rod 8 are passed by bearing pin and be connected, and fixture block and connecting rod 8 can rotate around bearing pin.Described cantilever beam piezoelectric vibrators 11 comprises ironed steel disc 12, electroceramics sheet 13 and mass 14; The two sides of described stalloy 12 is pasted with described piezoelectric ceramic piece 13 respectively; Described mass 14 is pasted onto the free end of described piezoelectric ceramic piece 13, can reduce the natural frequency of cantilever beam piezoelectric vibrators 11, makes it more easily resonate.The center of described flywheel 6 is thinning, and flywheel 6 is distributed with partial bores, and flywheel 6 when designing thickness and radius less, thus ensure that moment of inertia is less, so namely rotatable under the less driving moment effect of power transmission shaft 5.
