The wind turbine according to the present invention includes a vertical frame 10, a horizontal frame 20, a diaphragm 30, a turbine 200, a generator G and a guider 100 as shown in Figs. 2 and 3 .

As shown in FIG. 2, the vertical frames 10 are formed in a plurality of vertical planes, and are vertically installed on the ground, thereby forming a multi-tower.

The horizontal frame 20 is installed along the longitudinal direction of the vertical frame 10 while being orthogonal to the vertical frame 10 as shown in FIG.

3, the other end of the cross bar 22 constituting the horizontal frame 20 may be formed thinner than the one end portion. This is to prevent sagging of the cross bar 22 by reducing the load of the other end fixed to the connecting ring 23. [

The diaphragms 30 are formed in a disc shape as shown in Fig. 2 and are integrally fixed to the horizontal frame 20, respectively.

The turbine 200 is a component that provides rotational energy to the generator G by wind, and is rotatably installed between the diaphragms 30 as shown in FIG.

3, the rotary shaft 210 is rotatably installed between the diaphragms 30 and is connected to the generator G, and provides rotational force to the generator G as it is rotated by wind pressure .

3, the rotary shafts 210 may be continuously formed along the longitudinal direction of the vertical frame 10, or they may be elongated in a single body. When the rotary shafts 210 are composed of a plurality of rotary shafts 210, the rotary shafts 210 are independently rotated by different wind wind speeds depending on the height of the vertical frame 10.

The propeller 220 is a member for rotating the rotary shaft 210 while being pressed by the wind pressure of the wind. The propeller 220 is formed in a plate shape as shown in FIG. 6 and is fixed in a radial direction along the circumferential direction of the rotary shaft 210, And rotates together with the rotating shaft 210 while being pressurized. The propeller 220 is inserted into the rotary shaft 210 by a fixed shaft 220a as shown in FIG.

As shown in FIG. 6, the accelerator blade 230 is integrally provided at an end of the propeller 220 and is a member that accelerates the rotation of the rotary shaft 210 while rotating together with the propeller 220.

As shown in FIG. 6, the accelerating blade 230 is formed of a weight that is orthogonal to the propeller 220 and is fixed to the end of the propeller 220 to provide a weight, thereby providing a centrifugal force to the propeller 220, 210).

The acceleration vane 230 is composed of a head portion 231 and a tail portion 233 as shown in the figure. As shown in the figure, the head portion 231 protrudes in the rotational direction of the propeller 220 to form the eccentric center of gravity while being formed into a circular cross-section, thereby increasing drag due to wind pressure.

The tail portion 233 is formed to extend in a streamlined cross-section, which is formed integrally on the rear side of the head portion 231 and has a reduced width, thereby reducing the resistance of air.

Accordingly, the propeller 220 can accelerate the rotational force as the centrifugal force is provided by the weight of the accelerator blades 230, and the drag and lift force works smoothly by the head portion 231 and the tail portion 233, The rotation axis 210 can be rotated with the resistance minimized.

The generator G is a member that is connected to each turbine 200 as shown in FIG. 3 and generates electricity by converting kinetic energy due to rotation of the turbine 200 into electric energy. This generator (G) may be configured in any manner known to those skilled in the art.

The generator G may be directly connected to the rotary shaft 210 of the turbine 200 or may be connected to the rotary shaft 210 through an accelerator (not shown). The accelerator is a normal member that increases the number of revolutions of the rotating shaft 210 while supplying the rotating force of the rotating shaft 210 to the generator G. The accelerator is composed of a gear train having different gear ratios, And provides it to the generator (G).

In addition, the generator (G) may be provided with rectifiers (not shown) to convert alternating current into direct current, and then store the generated electric energy as it is connected to the battery. In addition, the generator G may be connected to an unillustrated regulator to output electricity while maintaining the generated electricity at a predetermined voltage.

7, the turbine 200 may include a rotating shaft 210, a rotating plate 240, a blade 250, and a stopper 260, for example.

Since the rotary shaft 210 is the same as that described above, detailed description is omitted.

7, the rotating plate 240 is rotated together with the rotating shaft 210 while being horizontally fixed to the upper and lower portions of the rotating shaft 210, do. As shown in the figure, a plurality of communication holes 240a are formed through the rotating plate 240 to communicate the wind.

The blade 250 is a member for rotating the rotating plate 240 with the wind pressure applied thereto. The blade 250 is formed in a plate-like shape as shown in FIG. 7 and is vertically installed between the pair of rotating plates 240. And a spinning state is established around the rotating shaft 210. The rotating shaft 210 is rotated in the radial direction.

As shown in the enlarged view of the lower part of FIG. 7, the blade 250 is fastened to the rotary plate 240 in a state in which one side 251 can be rotated in one direction, and the other side 253 is rotated and rotated by wind pressure.

The stopper 260 is a component that transmits the wind pressure applied to the blade 250 to the rotary plate 240 while controlling the rotation angle of the blade 250. The stopper 260 is integrally formed with the rotary plate 240, And a stop projection 261 formed to be protruded.

The stop protrusion 261 is disposed in the rotation locus of the blade 250 to control the rotation angle of the blade 250 in accordance with the engagement with the other side 253 of the blade 250, (253) so that wind pressure applied to the blade (250) is transmitted to the rotating plate (240) to rotate the rotating shaft (210).

It is preferable that the stop protrusion 261 is coated with a cushioning material such as urethane in order to reduce noise and impact caused by collision of the blade 250.

The stop protrusion 261 may be provided only on one side of the blade 250 to limit the rotation of the blade 250 due to wind pressure and may be provided on both sides of the blade 250 as shown in the lower part of FIG. It is possible to limit the rotation of the blade 250 due to the wind pressure as well as the reverse rotation of the blade 250 due to the rotation of the rotation plate 240 (return to the original position). When the stopper 261 is provided on both sides of the blade 250, it is preferable that the stopper 261 is formed to rotate within a range of the rotation angle A of the blade 250 within a range of 10 to 35 degrees.

Accordingly, the blade 253 is rotated about the one side 251 by the wind pressure of the wind and the rotation stops as the other side 253 of the blade 253 collides against the stop protrusion 261, To the stop projection 261 to rotate the rotary plate 240.

Here, the blade 250 is subjected to a drag force by the wind on the surface to which the wind pressure is applied, and the lift by the existing air acts on the opposite surface. Accordingly, the blade 250 rotates in a state in which the drag force and the lift force are balanced through the one-side rotation of the other side 253, thereby rotating the rotation plate 240 with the rotation resistance minimized.

7, the blade 250 may have a streamlined cross-section that is narrower from the end of the one side 251 to the end of the other side 253, The other side curvature portion 257 is provided.

As shown in FIG. 7, the one-side curved portion 255 is curved in a concave shape on one side facing the outer side of the rotary plate 240, thereby increasing drag due to wind pressure.

The other side curvature portion 257 is curved in a convex shape on the other side of the one side curvature portion 255 as shown in FIG. 7, thereby increasing the lift acting on the other side of the blade 250, .

Thus, the blade 250 smoothly acts on the wind by the one-side curvature portion 255 and the other-side curvature portion 257, so that the rotating plate 240 and the rotating shaft 210 are rotated in a state where the rotational resistance is minimized. . The blade 250 rotates together with the rotary plate 240, and then returns to the original position while being rotated on the opposite side as the lift on the other side curvature portion 257 is generated by the resistance acting on the other side curvature portion 257.

6, the blades 250 may be arranged in a plurality of rows along the circumferential direction of the swash plate 240, or alternatively may be arranged in a single row along the circumferential direction of the swash plate 240. The blade 250 is installed in a staggered alternating state in the case of a plurality of rows so that the rolling resistance of the rotating plate 240 can be further minimized as wind pressure is applied in multiple stages while forming an airflow passage between each row.

As shown in FIG. 2, the guider 100 is an element for guiding wind to the turbine 200 by forming an inlet port 100a through which the wind flows along the outer periphery of the turbine 200, The steel plate 110 and the steel plate fastener 120 as shown in FIG.

As shown in FIG. 3, the hoisting plate 110 is vertically installed between the diaphragms 30 and forms an inlet 100a in a radial state along the outer periphery of the turbine 200 as shown in FIG. 4 .

As shown in FIG. 5, the hoisting plate 110 is formed by bending the irregularities along the longitudinal direction repeatedly so that the inlet is formed in a zigzag shape as shown in FIG.

That is, as shown in FIG. 2, the hoisting plate 110 forms a staggered inlet port 100a at the outer periphery of the turbine 200 to generate a vortex in the wind while guiding the wind. Thus, therefore, the wind smoothly flows into the inlet port 100a and rotates the turbine 200.

5, the steel plate 110 may be formed to have a width W gradually increasing from the outside of the turbine 200 to the turbine 200 side.

4 and 5, as the concavity and convexity is repeatedly formed, the flow rate of the incoming wind is varied to accelerate the inflow speed of the wind, .

5, the throne plate 110 expands the flow rate of the wind through the concave portion 115 that gradually widens as shown in FIG. 5, and reduces the flow rate of the wind through the gradually narrowing convex portion 116, And at the same time, the pressure is changed to accelerate the inflow speed of the wind.

The steel plate fastener 120 is a component for integrally fixing the steel plate 110 to the diaphragm 30 and includes a steel plate bracket 121 and a fixing member 122 as shown in Fig. .

The steel plate bracket 121 is integrally fixed to the upper and lower ends of the steel plate 110 as shown in FIG.

The fixing member 122 may be constituted by, for example, a fixing bolt as shown in FIG. 5, and is fastened to the diaphragm 30 through the steel plate bracket 121.

The operation and operation of the present invention including the above-described components will be described.

The guider 100 guides the wind to the turbine 200 through an inlet port 100a formed radially by the steel plates 110. [

At this time, the hoisting plate 110 forms the inlet port 100a in a staggered shape through the unevenness, and as the width W gradually increases, the wind accelerates while being vortexed and flows into the inlet port 100a.

The propeller 220 constituting the turbine 200 rotates the rotary shaft 210 while being pressed by the wind pressure of the wind flowing into the inlet port 100a and the accelerator blade 230 rotates together with the propeller 220, Thereby accelerating the rotation of the rotary shaft 210.

Specifically, the accelerator blade 230 provides the center of gravity eccentrically through the head portion 231 in the rotating direction of the propeller 220, while increasing the drag force through the head portion 231, Thereby reducing the air resistance and accelerating the rotation of the propeller 220 and the rotation shaft 210. [

Accordingly, the rotary shaft 210 rotates together with the propeller 220 to generate rotational energy to the generator G to generate the generator G.

On the other hand, when the turbine 200 is composed of the blade 250 and the rotating plate 240, the blade 250 is pressed by the wind that flows into the inlet 100a. At this time, the other side 253 of the blade 250 rotates about the other side 253 while being rotated at an angle opposing the wind direction and the wind speed, and the rotation plate 240 is rotated by the rotation axis 210 ).

The blade 250 increases the drag force as the wind pressure is applied by the one curved portion 255 and increases the lift by the other curved portion 257 so that the rotation of the rotary plate 240 and the rotation axis 210, so that the rotary shaft 210 operates the generator G. [

As described above, the wind turbine of the present invention is capable of guiding wind smoothly to the turbine 200 as the hoisting plate 110 constituting the guider 100 forms the radial inlet port 100a, Since the inlet port 100a is formed in a zigzag shape by the irregularities of the steel plate 110, the wind can be guided to the turbine 200 while causing a vortex.

In addition, since the width W of the hoisting plate 110 is configured to be wider from the outside to the turbine 200, the flow of the incoming air is accelerated through the variable amount of the flow, so that the turbine 200 can rotate more smoothly.

Since the steel plate 110 is fixed to the diaphragm 30 by the steel plate bracket 121 and the fixing member 122, assembly of the steel plate 110 is convenient.

In addition, since the thickness of the cross bar 22 constituting the horizontal frame 20 gradually decreases toward the connection ring 23, the load is reduced, so that deflection of the cross bar 22 can be reduced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art that various changes, substitutions, and alterations can be made therein without departing from the spirit of the invention.
