[0071] In this case, as described above, the second blade 43 is plural, and the plurality of the second blades 43 are installed on the second rotating plate 42.

[0072] In addition, a third bearing 23 is installed between the second rotating shaft 41 and the first rotating shaft 31 to allow the second rotating shaft 41 to rotate separately from the first rotating shaft 31.

[0073] The third rotating gear 44 is formed at the other end of the second rotating shaft 41. The fourth rotating gear 45 is in gear with the third rotating gear 43 to rotate the power generation module 60 and thus generate power.

[0074] Meanwhile, it is preferable that the first blade 33 is formed to have a length relatively longer than that of the second blade 43.

[0075] The cone member 50 is installed on one side of the first blade member 30 and the second blade member 40 so that the wind moves toward the first and the second blade 33, 43.

[0076] The cone member 50 includes: a cone body 51 formed in a cone shape so that the wind moves toward the first blade member 30 and the second blade member 40; a first support frame 52 installed on one side of the central fixed shaft member 20 so that the cone body 51 is stably fixed, and a second support frame 53 installed on the outer surface of the second blade member so that the cone body 51 is stably fixed 40.

[0080] Meanwhile, the power generation module 60 generating power is installed between the second rotating gear 35 of the first blade member 30 and the fourth rotating gear 45 of the second blade member 40.

[0081] Hereinafter, according to a preferred embodiment of the present invention, a method of operating a wind power generator for street light will be described with reference to FIGS. 1 to 9.

[0082] FIG. 8 is a perspective view illustrating a wind power generator for street light according to a preferred embodiment of the present invention. FIG. 9 is a perspective view illustrating a wind power generator for street light according to a preferred embodiment of the present invention.

[0083] Referring to FIGS. 1 to 9, the wind power generator for street light of the present invention includes the first blade member 30, which is installed around the central fixed shaft member 20 and rotated by the first blade 33, and the second blade member 40, which is installed around the first blade member 30 and rotated by the second blade 43. The first blade member 30 and the second blade member 40 are formed in a double lap structure.

[0084] The first blade member 30 and the second blade member 40 are installed at an appropriate height by the post member 10, which is composed of the lower post 11 and the upper post 13. The upper post 13 is installed to be rotatable according to the wind direction.

[0085] In addition, since the cone body 51 is installed around the first blade member 30 and the second blade member 40, the first blade 33 and the second blade 43 can be supplied with a sufficient amount of air to rotate even when wind is weak.

[0086] That is, the cone body 51 allows wind to move toward the first and the second blade 33, 43 along the outer surface of the cone body 51, thereby rotating the first and the second blade 33, 43.

[0087] As the first blade 33 of the first blade member 30 is rotated by wind, the first rotating shaft 31 and the first rotating gear 34 formed on the first rotating shaft 31 rotate.

[0088] The first rotating gear 34 rotates the second rotating gear 35, and thus, the power generation module 60 generates power by the rotation of the second rotating gear 35.

[0089] In addition, the second blade 43 of the second blade member 40 is rotated by wind, and the second rotating shaft 41 and the third rotating gear 44 are rotated by the second blade 43.

[0090] The third rotating gear 44 rotates the fourth rotating gear 45 coupled to the power generation module 60, and thus, the power generation module 60 generates power.

[0091] Accordingly, the double blades of the first blade member 30 and the second blade member 40 can supply sufficient torque required for the rotation of the power generation module 60, and can generate power by rotating the power generation module 60 at high speed.

[0092] In addition, since the cone member 50 moves wind toward the first and the second blade 33, 43, power can be consistently generated even when wind is weak.

[0093] Although the invention made by the present inventor has been described in detail according to the above embodiment, the present invention is not limited to the embodiment and various modifications can be made without departing from the gist of the present invention.
