It includes a stopper for transmitting.

The stopper may be configured to include at least one stop protrusion integrally protruding from the rotating plate and disposed in the rotational trajectory of the blade, and supporting the other side of the blade while being caught by the other side of the blade being rotated.

In addition, the blade, characterized in that formed in a streamlined cross-section that narrows toward the end of the other side located on the opposite side of the one side from the end of the one side which is fixed to the rotating plate to enable the uniaxial rotation, One side curvature formed in a concave shape on one side facing outward to increase drag due to wind pressure acting on the one side; And the other side curvature formed in a convex shape on the other side facing the inside of the rotating plate to reduce the resistance of the air acting on the other side.

The present invention may further include a reducer that floats the rotary shaft installed in a vertical state inside the wind tunnel to reduce a starting load caused by the weight of the rotary shaft.

The reducer may include, for example, a wind tunnel fixing plate integrally fixed to the wind tunnel, through which the rotation shaft passes; A rotation shaft fixing plate integrally fixed to one end of the rotation shaft penetrating the wind tunnel fixing plate to face the wind tunnel fixing plate; And magnets which are respectively installed on the wind tunnel fixing plate and the rotating shaft fixing plate to face each other, are formed in the same polarity, and float the rotating shaft while separating the wind tunnel fixing plate and the rotating shaft fixing plate.

According to the wind turbine according to the present invention as described above, as the plurality of blades for rotating the rotating plate are each uniaxially rotated by the stopper to control the angle of rotation respectively, the plurality of blades respectively correspond to the wind speed or wind direction of the wind Since the rotation of the blade is minimized, the rotational resistance of the blade is minimized, so that the rotational force of the blade is smoothly transmitted to the rotating plate and the rotating shaft, thereby improving power generation efficiency.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted.

As shown in FIG. 2, the wind turbine 100 according to the present invention includes a rotating shaft 10, a rotating plate 20, a blade 30, and a stopper 40.

The rotary shaft 10 is a member installed in the wind tunnel 5 in a vertical state as shown in FIG. 4, connected to the generator G, and providing a rotational force to the generator G as it is rotated by the wind pressure.

Here, the wind tunnel (5) is a component that is installed in a vertical state while forming a tower shape as shown in Figure 3, the wind is introduced, as shown in Figure 4 is formed with an inlet hole (5a) along the outer circumferential surface It is introduced into the inside, and is partitioned into a plurality of layers by fixing frames 5b installed at equal intervals along the longitudinal direction. Also, the wind tunnel 5 may be formed in a hexagon as shown in FIGS. 3 and 5, or alternatively, may be formed in a polygon such as a triangle or a quadrilateral as shown in FIG. 6.

As shown in FIG. 3, the wind tunnel 5 is provided with a guide 7 along the circumference to guide the wind to the inflow hole 5a. As the guide 7 is formed in the shape of a cone as shown in FIGS. 3 and 4, the guide 7 causes vortex in the wind and flows into the inlet hole 5a.

The rotating plate 20 is a member that rotates together with the rotating shaft 10, and is configured as a pair as shown in FIG. 2 to rotate together with the rotating shaft 10 while being fixed to the upper and lower portions of the rotating shaft 20 in a horizontal state, respectively. do. The rotating plate 20 is a plurality of communication holes (20a) as shown in Figures 2 and 5 penetrating through the wind flowing into the inlet hole (5a) to the top.

Blade 30 is a member for rotating the rotating plate 20 while the wind pressure is applied, as shown in Figure 2 is formed long in a plate shape is installed in a vertical state between the pair of rotating plate 20, in Figure 5 A radial state is formed around the rotating shaft 10 while being disposed at equal intervals along the circumferential direction of the rotating plate 20.

The blade 30 is one side 31 is fastened to the rotating plate 10 by the fastening pin 30a as shown in the lower portion of Figure 4, according to the other side (by the wind pressure as shown in Figure 5) 33) rotates uniaxially about the fastening pin (30a).

The stopper 40 is a component that transmits the wind pressure applied to the blade 30 to the rotating plate 20 while controlling the rotation angle of the blade 30. For example, as shown in FIG. 2, each of the pair of rotating plates 20 is shown. It can be configured as a stop protrusion 41 integrally formed in the.

As shown in FIG. 5, the stop protrusion 41 is disposed in the rotation trajectory of the blade 30 to control the rotation angle of the blade 30 according to the other side 33 of the blade 30. By supporting the other side 33 in a locked state, the wind pressure applied to the blade 30 is transmitted to the rotating plate 20 to rotate the rotating shaft 10.

The stop protrusion 41 is preferably coated with a cushioning material 41a such as urethane as shown in an enlarged view in FIG. 4 in order to reduce noise and impact caused by the collision of the blade 30.

In addition, the stop protrusion 41 may be provided on only one side of the blade 30 as shown in FIG. 6 to limit the rotation of the blade 30 due to wind pressure, and as shown in FIG. As provided on both sides, as well as the rotation of the blade 30 due to wind pressure, it is also possible to limit the reverse rotation (return to the original position) of the blade 30 according to the rotation of the rotating plate 20. When the stop projection 41 is provided on both sides of the blade 30, as shown in Figure 5 it is preferable to form so as to rotate within the range of the rotation angle (A) of the blade 30 10 ° to 35 ° Do.

Accordingly, the blade 30 rotates uniaxially about the one side 31 by the other side 33 by the wind pressure of the wind flowing into the inlet 5a of the wind tunnel 5, and the other side 33 which rotates stops. As it collides with the 41, the wind pressure is transmitted to the stop protrusion 41 while the rotation is stopped to rotate the rotating plate 20.

Here, the drag 30 by the wind acts on the surface 30 is applied to the wind pressure, the lifting force by the existing air on the opposite surface is acting. Accordingly, the blade 30 rotates the rotating plate 20 in a state in which the rotational resistance is minimized by rotating in the balanced state of drag and lift through the uniaxial rotation of the other side 33.

On the other hand, the blade 30 is formed in a streamlined cross-section is narrower from the end of one side 31 toward the end of the other side 33 as shown in enlarged in Fig. 5 is curved formed to one side curvature 35 and The other side curvature 37 is provided.

As shown in FIG. 5, the one side curvature part 35 is curved in a concave shape on one surface facing the outside of the rotating plate 20 to increase drag due to wind pressure.

As the other side curvature 37 is curved in a convex shape on the other side of the one side curvature 35, as shown in FIG. 5, the other curvature portion 37 increases the lifting force acting on the other side of the blade 30 to increase the resistance of the air. Decrease.

Accordingly, since the drag 30 and the lifting force against the wind are smoothly acted by the one side curvature part 35 and the other side curvature part 37, the rotating plate 20 and the rotating shaft 10 in a state where the rotational resistance is minimized. Can be rotated. Then, the blade 30 returns to its original position while rotating in the opposite direction as the lifting force is generated in the other curvature portion 37 with the resistance acting on the other curvature portion 37 after rotating together with the rotating plate 20.

Meanwhile, the blades 30 may be arranged in a plurality of rows along the circumferential direction of the rotating plate 20, as shown in FIGS. 5 and 6. Alternatively, the blades 30 may be arranged in a single row along the circumferential direction of the rotating plate 20. have. When the blade 30 is composed of a plurality of rows alternately installed in an alternating state to form an air flow passage between each row, as the wind pressure is applied in multiple stages, the rotational resistance of the rotating plate 20 can be further minimized.

On the other hand, the turbine 100 for a wind turbine of the present invention may further comprise a reducer 50 as shown in FIG.

The reducer 50 is a component that reduces the maneuvering load caused by the weight of the rotating shaft 10 by floating the rotating shaft 10 installed vertically inside the wind tunnel 5, for example, as shown in FIG. 4. It may be configured to include a fixed plate 51, a rotating shaft fixing plate 53 and a magnet (55).

The wind tunnel fixing plate 51 is integrally provided in the wind tunnel 5, as shown in FIG. 4, and the rotation shaft 30 penetrates.

As shown in FIG. 4, the rotation shaft fixing plate 53 is integrally fixed to an end portion of the rotation shaft 10 penetrating the wind tunnel fixing plate 51 so as to face the wind tunnel fixing plate 51.

As shown in FIG. 4, the magnets 55 are respectively installed on the air hole fixing plate 51 and the rotating shaft fixing plate 53 so as to face each other, and have the same polarity to separate the wind tunnel fixing plate 51 and the rotating shaft fixing plate 53. Float the rotating shaft (10).

That is, the magnet 55 is the repulsive force acts as they face each other with the same polarity, so that the rotary shaft fixing plate 53 is spaced apart from the wind tunnel fixing plate 51 by the repulsive force of the magnet 55 to float the rotary shaft 10. . Accordingly, the load of the rotating shaft 30 is increased while the floating shaft 30 is reduced, thereby minimizing the starting load during the initial rotation, thereby improving power generation efficiency of the generator G through smooth rotation.

Meanwhile, the rotation shaft fixing plate 53 may be installed to face the wind tunnel fixing plate 51 at the lower portion of the wind tunnel fixing plate 51, as shown in FIG. 4. In this case, the magnet 55 is installed with a different polarity to raise the rotating shaft 10 while pulling the rotating shaft fixing plate 53 toward the wind tunnel fixing plate 51 through the attraction.

On the other hand, although the reducer 50 is shown as being installed only in the rotary shaft 10 disposed on the upper portion of the wind tunnel 5 in FIG. 4, each of the reducers 50 also has a respective rotation axis 10 continuous in the longitudinal direction of the wind tunnel 5. Can be prepared.

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

The turbine 100 for a wind turbine of the present invention is built in the wind tunnel 5 as shown in FIG. 3 and forms a single module with the generator G as shown in FIG. 4 to extend the longitudinal direction of the wind tunnel 5. Plurally installed.

The blade 30 is pressurized by the wind introduced into the inlet 5a of the wind tunnel 5 through the guide 7. The blade 30 rotates at an angle opposite to the wind direction and wind speed while the other side 33 rotates uniaxially with respect to one side 31, and is caught by the stop protrusion 41 to rotate the rotating plate 20 with the rotating shaft 10. Rotate together

At this time, the blade 30 increases the drag force as the wind pressure is applied by the one side curvature 35, the increase in the lift force by the other side curvature 37 to reduce the air resistance in the rotating plate 20 and Rotate the rotary shaft 10.

Accordingly, the rotating shaft 10 rotates together with the rotating plate 20 to provide rotational energy to the generator G to generate the generator G.

At this time, the rotating shaft 10 is driven by the repulsive force of the magnet 55 constituting the reducer 50, the driving load is minimized to smoothly rotate and drive the generator (G).

Specifically, the rotary shaft 10 is rotated in a floating state as the rotary shaft fixing plate 53 is spaced apart from the wind tunnel fixing plate 51 by the repulsive force between the magnets (55).

 Accordingly, the rotating shaft 10 is rotated to minimize the rotational resistance by the blade 30 at the same time the start load is minimized by the reducer 50 to improve the power generation efficiency of the generator (G).

As described above, the wind turbine for the wind turbine according to the present invention includes a plurality of blades 30 for rotating the rotating plate 20, while the rotation angles A are controlled by the stopper 40 while the blades 30 rotate uniaxially, respectively. Since the blades 30 each rotate at an angle corresponding to the wind speed or the wind direction, the rotational resistance of the blades 30 is minimized so that the rotational force of the blades 30 is smoothly transmitted to the rotating plate 20 and the rotating shaft 10. Power generation efficiency of the generator (G) can be improved.

In addition, since the rotary shaft 10 may be independently installed in the wind tunnel 5 of the tower type by forming a module together with the pair of rotating plates 20 and the plurality of blades 30, the different shapes according to the altitude. Power generation efficiency can be improved by rotating each of the wind speeds.

In addition, since the stopper 40 is composed of a stop protrusion 41 disposed in the rotational trajectory of the blade 30 in a state where the stopper 40 protrudes, the production is convenient, and the rotation angle through the locking of the blade 30 ( As well as the control of A), the wind pressure applied to the blade 30 can be stably provided to the rotating plate.

In addition, as the blade 30 is formed in a streamlined cross section, the blade 30 may be more uniaxially rotated more stably, and both sides of the blade 30 are curved by the curvatures 35 and 37. Since drag and lift by wind are simultaneously applied to the blade 30, the rotational resistance of the blade 30 can be minimized.

In addition, since the rotational force of the rotating shaft 10 increases as the starting load by the weight of the rotating shaft 10 is reduced by the reducer 50, the power generation efficiency of the generator G may be further improved.

Specifically, since the magnet 55 constituting the reducer 50 spaces the wind tunnel fixing plate 51 and the rotating shaft fixing plate 53 through the repulsive force of the same polarity, the magnet 55 may be permanently used without any separate power.

While specific embodiments of the present invention have been described above by way of example, these are for illustrative purposes only and are not intended to limit the protection scope of the present invention. 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.
