Thermal power plants need to generate power by burning fuel such as coal or petroleum. Therefore, a lot of combustion gas is generated, which increases air pollution. Nuclear power does not emit combustion gases polluting the air, but a large amount of radiation waste that is fatal to humans is generated. It is discharged, hydroelectric power does not emit a combustion gas or radiation waste, etc. and does not require a separate fuel, while destroying the environment there is a problem that is not environmentally friendly.

It must be interpreted to mean meanings and concepts.

Hereinafter, a windmill for a generator according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a side view of a power generator showing a state in which a generator windmill is installed according to an embodiment of the present invention, Figure 2 is a perspective view showing the configuration of a generator windmill according to an embodiment of the present invention, Figure 3 Top view showing the configuration of a windmill for a generator according to an embodiment of the present invention.

First, referring to FIGS. 1 to 3, a power generator for generating electric power using a flow of a fluid includes a generator 10 in which a rotating shaft 11 of a rotor is perpendicular to the ground, and the generator 10. It includes a windmill 100 is installed on the rotating shaft 11 so that the rotating shaft 11 of the rotation by the fluid.

The windmill 100 is coupled to the rotating shaft 11 and rotated by a fluid, and is provided on the outside of the rotating body 110 so that the amount of fluid flowing into the rotating body 110 is reduced and increased. And fluid induction device 130. The fluid inductor 130 is installed in the generator 10 so that the rotating body 110 is located inside, and rotates around the rotating body 110.

4 to 6 will be described in more detail the configuration of the rotor and the blade of the present invention.

Figure 4 is a perspective view showing the configuration of a rotating body according to an embodiment of the present invention, Figure 5 is a perspective view showing the configuration of a wing according to an embodiment of the present invention, Figure 6 is an embodiment of the present invention 5 is a cross-sectional view taken along the line AA of FIG.

4 to 6, the rotor 110 is coupled to the hub 111 coupled to the rotary shaft 11 of the generator 10 and the hub 111 so that the rotary shaft 11 is rotated by the flow of the fluid. The upper support member 115 and the lower support member coupled to the upper and lower ends of the wing 120, respectively, to prevent the wing 120 from being damaged by a plurality of wings 120 coupled to each other and a strong fluid such as a typhoon. 117).

The blade 120 is installed at regular intervals along the circumferential direction of the hub 111 so that the rotor 110 rotates more smoothly by the kinetic energy of the fluid. An inner portion of the wing 120 close to the hub 111 is formed with a fluid through-hole 120a in the longitudinal direction to allow fluid flow therethrough.

Forming the fluid through hole (120a) in the blade 120 is the fluid flowing between the adjacent wings 120 hit the wing 120 to rotate the blade 120, through the fluid through hole (120a) It is intended to flow out. This prevents the strength of the fluid flowing into the blades 120 by the backflow fluid generated as the fluid flow hits the blades 120 and flows back from the inside of the blades 120 to the rotating body 110 This is to improve the rotational force of the. As such, when the fluid backflow phenomenon generated in the rotor 110 is reduced by the blades 120, the rotational force of the rotor 110 is further improved, and thus, the power generation efficiency of the generator 10 is improved.

The blade 120 according to the present embodiment is preferably formed to have a width at which the fluid through hole 120a is formed to be 1/2 or less with respect to the entire width of the blade 120. Here, when the width of the fluid through-hole 120a is formed so that the width is greater than 1/2 of the total width of the blade 120, the amount of fluid passing through the fluid through-hole 120a is too large, rather the wing The force of the fluid acting on the 120 is sharply lowered so that the rotational force of the rotating body 110 is lowered.

The wing 120 according to the present embodiment is formed so that lift is generated in the direction in which the rotating body 110 rotates, which will be described in more detail with reference to FIG. 6.

As shown in FIG. 6, the blade 120 is bent at a lift generation unit 121 in which lift is generated by a flow of a fluid, and a trailing edge T of the lift generation unit 121. And a fluid through part 123 in which a fluid through hole 120 a is formed. Lifting unit 121 is formed on both sides of the corresponding asymmetric streamline so that the lift is generated by the flow of the fluid, one surface 121a is formed to have a greater curvature than the other surface (123b). Lifting unit 121 has a greater curvature than one surface (121a) compared to the other surface (121b), when the fluid flows into the leading edge (Leading Edge) (L) side, the curvature is formed larger one side (121a) side Lifting force is generated toward one surface 121a due to the pressure difference between the one surface 121a and the other surface 121b generated due to the faster flow of the fluid than the other surface 121b.

At this time, bending the fluid passage portion 123 at the trailing edge T of the lift generation portion 121 is the direction of the fluid flowing through the fluid passage portion 123 to the other surface 121b of the lift generation portion 121. This is to increase the lift generated by the lift generating unit 121 in turn. To this end, a straight portion 123b bent at the trailing edge T is formed between the trailing edge T and the fluid through hole 120a in the fluid through portion 123. That is, the straight portion 123b of the fluid through portion 123 serves as the high lift force generating flap of the lift generation unit 121, thereby increasing the lift generated by the lift generation unit 121.

In addition, the blade 120 is due to the peeling phenomenon generated at the trailing edge (T) of the lift generating unit 121 due to the straight portion 123b bent at the trailing edge (T) of the lift generating unit ( A slot 123a through which a fluid passes is formed in a straight portion 123b that is bent at the trailing edge T so that separation is reduced. Accordingly, the fluid guided to the trailing edge T via the other surface 121b of the lift generating unit 121 through the slot 123a, and then trailing through one surface 121a of the lifting generating unit 121. Since it is joined with the fluid guided to the edge (T), the peeling phenomenon is reduced to increase the lifting force of the lifting unit 121.

Next, the fluid inductor 130 for reducing and increasing the fluid flowing into the rotating body 110 will be described in detail with reference to FIGS. 2, 7 and 8.

7 is an enlarged plan view of a main portion of a fluid induction apparatus according to an embodiment of the present invention, and FIG. 8 is a side view showing the configuration of the fluid guide plate and the first driving member according to an embodiment of the present invention.

The receiving hole 133a is formed in such a manner that the lower end of the rotating body 100 is positioned at the upper portion of the rotating body 100. That is, the fluid guide 130 is the upper plate 131 is rotatably coupled to the rotary shaft 11 of the generator so that the rotor 110 is located inside the receiving hole (133a), the lower plate 133 is the generator 10 Is installed at the top of the

The fluid guide plate 135 is rotatably installed between the upper plate 131 and the lower plate 133 so as to reduce and increase the fluid flowing into the rotating body 110 between the upper plate 131 and the lower plate 133. do. The fluid guide plate 135 is positioned at a portion of which one side is close to the center of the upper / lower plates 131 and 133 and the upper / lower plate is positioned at a portion of which the other side is close to the outer circumference of the upper / lower plates 131 and 133. 131, 133 is installed between. And one side top and bottom of the fluid guide plate 135 is rotatably coupled to the upper plate 131 and the lower plate 133, respectively.

In addition, the fluid guide plate 135 is rotated by the first driving member 137, and the upper and lower plates 131 and the lower plate 133 to the top and bottom so as to be smoothly rotated by the first driving member 137. The rollers 139 in contact with each other are provided. In addition, guide grooves 131b and 133b are formed in the upper plate 131 and the lower plate 133 to which the roller 139 is in contact, and the guide grooves 131b and 133b are formed in the upper plate 131 and the lower plate ( 133 is formed along the trajectory that is contacted and rotated.

The first driving member 137 has a first rotating shaft 137a which is provided at the upper and lower ends of the side of the fluid guide plate 135, respectively, and a first rotating shaft 137a provided at the lower end of the fluid guide plate 135. And a first driven gear 137b axially coupled to the first driven gear 137b and meshed with the first driven gear 137b and forward / reversely rotated by the first driving motor 137c. At this time, a space portion is formed at the lower end of the fluid guide plate 135 to which the first rotation shaft 137a is coupled so that the first driven gear 137b is installed.

The first driven gear 137b of the first driving member 137 is axially coupled to the first rotation shaft 137a to be positioned above the lower plate 133, and the first driving motor 137c is disposed on the lower surface of the lower plate 133. And a driving shaft penetrates the lower plate 133 and is axially coupled to the first driving gear 137d.

The fluid inductor 130 according to the present embodiment is rotated about the rotor 110 by the second driving member 140. The second driving member 140 is a rack 141 formed on the outer circumferential surface of the lower plate 133 of the fluid induction machine 130 and a pinion gear meshing with the rack 141 to rotate the lower plate 133. 143 and a second drive motor 145 for rotating the pinion gear 143 forward / backward. The second drive motor 145 is mounted to the generator 10.

Meanwhile, in this embodiment, six fluid guide plates 135 of the fluid inductor 130 are formed at regular intervals along the outer side of the rotor 110, but as shown in FIG. Only three may be formed. The length of one fluid guide plate 135 may be longer than the length of the other fluid guide plate 135.

The operation and operation of the windmill for a generator according to an embodiment of the present invention configured as described above will now be described in detail.

9 to 11 is a fluid flow diagram showing the flow of the fluid guided to the windmill for the generator according to an embodiment of the present invention.

First, referring to FIGS. 3, 7, and 9, when the first driving motor 137 is rotated forward to increase the fluid flowing into the rotating body 110 through the fluid guide plate 135, the neighboring fluids are mutually adjacent. As the space between the guide plate 135 is widened, the inflow area of the fluid that can flow into the rotating body 110 is increased, thereby increasing the amount of the fluid guided to the rotating body 110.

Then, the fluid flowing into the rotating body through the fluid guide plate 135 hits the wing 120, the kinetic energy of the fluid is transmitted to the rotating body (110). At this time, since the fluid hits the wing 120, it flows out through the fluid through-hole 120a, the flow direction is switched to reduce the backflow fluid induced to the outside of the wing 120. In addition, the fluid flowing through the fluid through-hole (120a) is to transmit the kinetic energy to the blade 120 is located next, the rotational force of the rotor 110 is further increased.

That is, the reverse body flow generated outside the rotor 110 by the fluid through hole 120a of the blade 120 is reduced, and the fluid induced in the blade 120 is increased to be transmitted to the blade 120. The kinetic energy of the fluid is increased.

In addition, lift is generated toward one surface 121a with a large curvature due to the pressure difference between one surface 121a and the other surface 121b generated when fluid flows into both sides of the lift generating unit 121 of the wing 120. While the rotational force is further increased in the direction of rotation of the rotating body (110). That is, when the rotational force is generated while the fluid hits the wing 120, the lift is generated in the rotational direction of the rotor 110 also in the lifting unit 121 of the wing 120 by the flow of the fluid, the rotating body The rotational force of 110 is further increased.

In addition, after the fluid guided through the other surface 121b of the lift generating unit 121 to the trailing edge T passes through the slot 123a, the trailing edge passes through the one surface 121a of the lifting generating unit 121. Since joining with the fluid (T), the peeling phenomenon generated in the lift generating unit 121 is lowered to increase the lift of the lift generating unit 121.

On the other hand, if the velocity of the fluid is too strong, such as a typhoon, as shown by the dashed-dotted line of FIG. 9, the first drive motor 137c is rotated in reverse to rotate the fluid guide plate 135 toward the rotating body 110. By minimizing the area that the fluid can be introduced into the rotating body (110). Then, the area in which the fluid can flow into the rotating body 110 is reduced, so that the strength of the fluid flowing into the rotating body 110 is weakened, so that the rotating body 110 is damaged or deformed due to the high speed rotation. It can prevent it beforehand.

Next, a windmill for a generator according to another embodiment of the present invention will be described in detail with reference to FIGS. 13 to 15.

Specifically, since the rotary wing 230 receives a constant elasticity to the other surface side by the compression force of the tension spring 263, when the fluid flows into one surface of the rotary wing 230, the rotary wing 230 is more easily rotated The fluid through hole 221 is opened. In addition, since the tension of the tension spring 263 is controlled by the adjustment bolt 265, the rotation of the frame 220 of the rotary wing 130 according to the strength of the fluid flow is adjusted more finely.

That is, when the flow of fluid is weak, the tensioning bolt 265 is rotated to tension the tension spring 263 so that the tensioning force of the tension spring 263 acts on the pivoting blade 230 so that the weak blade flows the pivot blade 130. ) Is easily opened. And when the flow of the fluid is stronger, by rotating the adjusting bolt 265 to compress the tension spring 263, the tension of the tension spring 263 acting on the pivoting wing 230 is reduced so that the pivoting wing 230 It requires greater power so that it can be rotated.

Rotating body 200 according to the present embodiment as described above is any one of the rotating wing that the fluid hits one surface of the rotating blades 230 of the position symmetrical about the rotation axis 11 when the fluid is introduced into the rotating body 230 seals the fluid through-hole 221 of the frame 220, and the other rotor blade 230 in which the fluid strikes the other surface is rotated by the flow of the fluid while the fluid through-hole ( 221 is opened. Accordingly, since the rotating blade 230 which receives the force in the direction opposite to the rotation of the rotating body 200 by the flow of the fluid rotates, the fluid through-hole 121 is opened, so that the resistance to the fluid flow is reduced and the rotating body ( The rotational force of 200 is further increased.

In addition, when the fluid flows along both sides of the rotary blade 230, lifting force is generated in the rotational direction of the rotor 200 to further increase the rotational force of the rotor 200.

In the present exemplary embodiment, the windmill 100 is rotated by the flow of the fluid, for example, but when the windmill 100 is installed in the sea, the windmill 100 may be operated by the force of the tidal current.
