The upper cover 145 and the lower cover 147 are inserted into the upper end side and the lower end side of the support shaft 110 while the support shaft 110 is positioned inside the outer cylinder 141, When the cover 145 and the lower cover 147 are coupled to the upper end surface and the lower end surface of the outer cylinder 141 respectively, the housing 140 can be installed on the support shaft 110 .

The upper cover 145 and the lower cover 147 are connected to the upper end side of the support shaft 110 and the upper cover 145 so that the upper cover 145 and the lower cover 147 can be inserted into the upper end side and the lower end side of the support shaft 110, And the flange 112 may be formed at the upper end and the lower end of the support shaft 110. [

The field magnet 150 may be installed on the inner peripheral surface of the outer cylinder 141 of the housing 140 and may be fixed to the inner peripheral surface of the field iron core 151, And may include a plurality of magnets 153 attached at intervals. Since the field 150 is provided in the outer cylinder 141, the field 150 is supported on the support shaft 110 via the outer cylinder 141 and rotated.

Ring-shaped supporting stems 141a, 151a (see FIG. 3) can be respectively formed on the inner peripheral surface on the lower end side of the outer cylinder 141 of the housing 140 and the inner peripheral surface on the lower end side of the field iron core 151, The lower surface of the field iron core 151 and the lower surface of the magnet 153 can be contacted and supported by the supporting frame 141a of the magnetic core 141 and the supporting frame 151a of the field core 151. [ This prevents the field iron core 151 and the magnet 153 from falling to the lower side of the outer cylinder 141 and the field iron core 151, respectively.

An armature 160 may be fixedly installed on an outer circumferential surface of the support shaft 110 positioned on the center side of the outer cylinder 141. The armature 160 may include a ring-shaped armature core 161 having an inner peripheral surface fixed to the outer peripheral surface of the support shaft 110 and a coil (not shown) wound around the outer peripheral surface of the armature core 161.

When the housing 140 is rotated by the blade 180 to be described later, the field 150 rotates, electricity is generated by the action of the rotating field 150 and the fixed armature 160, Is stored in a capacitor (not shown) through the coil.

The lead wire 163 of the coil flows into the support shaft 110 through the first through hole 116a formed in the support shaft 110 and then passes through the second through hole 116b to the outside of the support shaft 110 And the end side of the lead wire 163 drawn out to the outside of the support shaft 110 may be connected to the capacitor.

The armature 160, the field magnet 150 and the outer cylinder 141 may be concentrically arranged and the outer peripheral surface of the armature core 161 and the inner peripheral surface of the field core 151 are preferably opposed to each other.

The outer circumferential surface portion of the support shaft 110 positioned at the center of the outer cylinder 141 is equivalent to the outer circumferential surface portion of the support shaft 110 located inside the field 150, And may be the same as the outer circumferential surface portion of the support shaft 110 between the upper cover 145 and the lower cover 147. [

A support member 118 may be formed on an outer circumferential surface portion of the support shaft 110 between the upper cover 145 and the lower cover 147. An inner circumferential surface and a lower surface of the armature 160 are supported by the support member 118 .

The support member 118 includes a support plate 118a protruding radially outward from the outer circumferential surface of the support shaft 110 and a support tube 118b protruded upward from the upper surface of the support plate 118a. ). The inner peripheral surface of the armature core 161 is supported on the outer peripheral surface of the support tube 118b and the lower surface of the armature core 161 can be supported on the upper surface portion of the support plate 118a positioned outside the support tube 118b .

A plurality of blades 180 may be provided radially around the support shaft 110 on the outer circumferential surface of the outer cylinder 141 of the housing 140. The blade 180 may be installed in the outer cylinder 141 via a connecting bar 143.

The blade 180 rotates the housing 140 while revolving around the support shaft 110 by the drag force generated by the wind acting on the front or rear of the blade 180. The blade 180 rotates the housing 140 by the lifting force generated by the wind acting on its side, It is possible to rotate the housing 140 while revolving around the shaft 110.

The portion of the upper cover 145 on the side of the through hole 145a and the lower cover 147 and the portion of the lower cover 147 on the side of the through hole 145a and 147a, (145b) and (147b) may be formed. That is, even if the wind force is weakened during the high-speed rotation of the housing 140 by the centrifugal force, the housing 140 rotates at a high speed for a predetermined time due to inertia. However, since the weight of the housing 140 is relatively heavy by the weights 145b and 147b, the housing 140 can smoothly rotate at high speed for a predetermined time.

Since the weight of the housing 140 is relatively heavy by the weights 145b and 147b, it can be stably centered when the housing 140 is installed on the support shaft 110. [

The wind turbine according to the present embodiment is connected to the outer circumferential surface of the housing 140 of the power generation unit 130 via the connecting bar 143 by the wind rotating blade 180. That is, since the blade 180 is directly connected to the power generation unit 130 without interposing a separate power transmission unit, it can be downsized and the cost can be reduced.

4 is a perspective view of a wind turbine generator according to another embodiment of the present invention, which will be described.

As shown in the figure, a plurality of wind power generators according to the present embodiment may be stacked.

In detail, the support shaft 110 can be interconnected along the length direction.

It is a matter of course that the power generating unit 130 is installed on the support shaft 110, respectively.

Then, one or a plurality of wind power generators can be installed and driven as needed, so that the power generation capacity can be adjusted.

When a plurality of wind turbine generators are installed, the coils of the armature 160 (see FIG. 2) of each wind turbine generator may be connected in series or in parallel to the capacitors.

When a plurality of wind turbine generators are installed, the flange 112 may not be formed on the lower end of the support shaft 110 of the lowermost wind turbine generator, and the flange 112 may not be formed on the support shaft 110 of the uppermost wind turbine generator. The above-mentioned weather information collecting device may be mounted on the flange 112 formed at the upper end.
