Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of small wind-driven generator described in the utility model, comprises elastic element (7), piezoelectric element (8), bolt (5), nut (4), screw (9).Also comprise hollow cylindrical shaft (1) and be fixedly installed in protecting sheet (2) and the slot (3) of described hollow cylindrical shaft surrounding, arrange and also can to avoid the while that protecting sheet (2) losing efficacy for preventing elastic element (7) to cause because external wind-force is excessive distortion excessive that piezoelectric element (8) destroys because being out of shape excessive, positioning block (6), bearing (14), bearing (ball) cover (10), wind-force bar (11), gear (12), small generator (13), described hollow cylindrical shaft (1) upper surface is provided with bearing support (101) and tapped hole; Described bearing support (101) is placed with bearing (14); Described bearing (14) is provided with bearing (ball) cover (10), and bearing (ball) cover (10) is for the working life of the dust-proof prolongation bearing (10) to bearing; Described bearing (ball) cover (10) is provided with tapped through hole and filler 1001, arranges the lubrication that filler is convenient to for bearing (10); Described wind-force bar (11) is arranged on bearing (in the inner ring of 14; The end of described wind-force bar (11) is provided with gear (12); Described gear (12) is meshed with the gear (15) on small generator (13); Described slot (3) is provided with elastic element (7); Described elastic element (7) is provided with positioning block 6; Described positioning block 6 is provided with tapped through hole; (7) are pasted with piezoelectric element 8 to described elastic element.
Filler (1001) on described bearing (ball) cover (10) is other is provided with circular lid (1002), circular lid (1002) for sealing filler (1001), when placing dust enter bearing (14) to opening when circular lid (1002) annotate closedown circular lid 1002 during bearing (14) filling oiling agent.
It is increase progressively with 5-10mm that described wind-force bar (11) works as top end diameter increase from bottom, and bottom diameter is less than hollow cylindrical shaft (1) intracavity diameter 5-10mm
