As a new energy source that can replace fossil fuels such as petroleum, there are many new energy sources for humans to pursue, including solar energy, wind energy, artificial sun, hydrogen energy, sea water energy, and bio energy. Among them, like other energy sources, wind power is a new energy source of the future that is attracting attention due to its eco-friendliness and renewables.

Wind power is a natural source of pollution-free energy. It is the current generation technology that is the most economical energy source among the alternative energy sources. It is a generation technology that directly supplies the power generated by converting the wind power to rotational power to the power system or the consumer. In other words, it generates electricity through the energy conversion process of wind power, and the produced power can be consumed by home, industrial, etc., or sold by reversing power to KEPCO. If such wind power is used, the land use efficiency can be improved by utilizing the sites such as mountains, coastal backcountry, and embankments.

As described above, in the blade piece 10 of the present embodiment, the busta piece 10C receives the wind blowing to the outer circumference of the blade modularized wind power generation system 100 to be formed to perform a function of increasing the rotational force of the wind power generation. It is a component.

First, the crescent moon-shaped busta piece 10C as shown in (A) is the most generally conceivable busta piece 10C shape, and the center is concavely recessed like a crescent moon. Next, (B) is the same concept as (A) but its shape is 'c' shape, and (C) shape is a busta piece (10C) having a flat shape, which is located at the end of the outer periphery of rotation. This busta piece (10C) is to receive a stronger wind to generate a force, a case similar to the arrow.

In addition, the blade piece body 10B of the blade piece 10 is a blade piece in order to increase the rotational force by the power generation medium received from the outside to the surface of the blade piece body 10B of the semi-circular shape, as shown It is possible to add at least one auxiliary booster piece 10D that is curved outward from the center of the body 10B to form a concave shape. In addition, such an auxiliary booster piece 10D is formed at one or more necessary points on at least one side of the inner and outer sides of the semi-circular shape to the surface of the blade piece body 10B.

Referring again to FIG. 1, the blade piece 10 of the present embodiment forms a rotary pressing end 10E in such a manner that an upper portion coupled to the blade piece body 10B protrudes from the blade piece body 10B. The rotary pressurization stage 10E receives the power generation medium from the outside and performs rotational pressure. As will be described later, this contributes to increasing the wind power generation by increasing the rotational efficiency of the blade modular wind power generation system (100).

In the blade modular wind power generation system 100 of the present embodiment, the blade piece body 10B is a bus blade piece 10C and another blade piece 10 on top of the blade piece body 10B that is connected to the boot piece piece 10C. When combined with a) is formed a plurality of assembly grooves (10H) for adjusting the angle of coupling to form a shape to be completed. The plurality of assembly grooves 10H may be divided into a main assembly groove 10Ha and an auxiliary assembly groove 10Hb. In the present embodiment, as shown, one main assembly groove 10Ha and a plurality of auxiliary assembly grooves ( 10Hb) is formed.

10 is a view for explaining the upright blade of the blade modular wind power generation system of FIG.

As shown, the blade modular wind power generation system 100 according to the present embodiment may be broadly classified into a blade 110, a booster 120, a shaft shaft 130, and a power generation module 140.

One of the important contents of the blade modular wind power generation system 100 of the present embodiment is that the blade 110 can be modularized and configured, and according to the configuration and assembling of such modularization, characteristics and effects different from those of conventional wind power generation can be achieved. Indicates.

The modularization concept of the blade 110 is to form the blade 110 of the present blade modular wind power generation system 100, the blade segment (110s) formed by the blade piece 10 is combined to a certain height as necessary. . That is, the blade module 110m may be formed by assembling and combining several blade segments 110s, or may be formed by assembling and combining dozens or hundreds of blade segments 110s.

First, as described above, the blade 110 has a predetermined thickness and has a semi-circular shape as a whole to receive a power generation medium from the outside, and is divided into a conformal shape at one end to be coupled to the central shaft shaft 130. 10 A of axial coupling parts are formed, and the blade piece 10 in which the busbar piece 10C is formed in concave shape so that it may face in the same direction as a semi-circle shape at the other end may be 2 pieces in this embodiment. It is formed by using. The shaft segments 10A of each of the blade pieces 10 are combined to form blade segments 110s, and the blade segments 110s thus formed are stacked by a predetermined height to form a blade module 110m and such blades. At least one module 110m is combined to form the blade 110.

In addition, in the blade modular wind power generation system 100 of the present embodiment, the rotary booster 120 is padded outside the blade 110 and formed together with the blade 110 through the lamination of the blade segments 110s in a bone shape. It is a component part.

In addition, the shaft shaft 130 is supported in a rotatable state for the power generation of the present blade modular wind power generation system 100, is formed in the form of a pillar-shaped shaft to rotate by an external rotational force.

And the power generation module 140 is located on the extension line of the shaft axis 130 is a component that generates power by receiving the rotational driving force of the shaft axis (130).

It is necessary to prepare each component for the configuration of the blade modular wind power generation system 100 according to the present embodiment, but it is particularly important to prepare the blade 110 well according to the wind power to be performed.

For the blade 110 of the present embodiment, first, it is important to determine how many blade pieces 10s to form the blade segment 110s. As shown, in the blade modular wind power generation system 100, one blade segment 110s may be formed by assembling and combining two blade pieces 10, and the blade pieces 10 may be three or four, or the same. One blade segment 110s may be formed as described above. What is important is to form the blade segment (110s) in what form can be good for the installation environment according to the efficiency of wind power or the situation. The shape of the blade segment 110s is preferably taken into consideration of the overall situation of the blade modularized wind power generation system 100 to be completed, and here, the two blade pieces 10 are assembled by being engaged with each other in the blade segment 110s. Forming, and will be described based on the process of forming the blade 110 by modularizing the formed blade segment (110s).

In each case, the shaft coupling portions 10A of the blade pieces 10 are coupled to face each other to form the blade segment 110s as shown.

In addition, the assembly configuration of the blade modular wind power generation system 100 according to the present embodiment is to proceed in a manner of largely preparing each of the components separately and assembled, the blade piece 10 or the blade on the shaft shaft 130 The segments 110s may be distinguished by assembling one by one.

In addition, according to the completion form of the blade 110 can be largely divided into a twist (twist) form and an upright form.

First, the twisted blade 110 is formed in a twisted shape as a whole by combining the blade piece 10 of the upper layer and the blade piece 10 of the lower layer so as to be shifted from each other at a predetermined angle.

In this process, one blade piece 10 is combined by setting it upright in an upright form without adjusting a desired shape or angle θ, for example, the angle θ, or by adjusting it to a desired degree such as 2 degrees, 3 degrees, 4 degrees, and the like. In addition, the blade 110 may be formed by continuing the process of joining another blade piece 10 to the blade piece 10, which will be described later, but is the same as in the case of laminating and then forming the blade segment 110s.

The blade 110 of this embodiment in the assembly process, the upper blade in the inner bone shape when the upper blade piece 10 and the lower blade piece 10 is coupled by the rotary pressing stage 10E described above. The lower blade piece 10 protrudes more than the piece 10, and is forced by the wind blown into the upper surface of the protruding lower blade piece 10.

In addition, as shown in the blade modular wind power generation system 100 of the present embodiment, the membrane plate 150 is formed in a panel form to block any one or more of the upper and lower portions of the blade 110 is formed.

And in the blade modular wind power generation system 100 of the present embodiment, unlike the above-described, when the blade piece 10 of the upper layer and the lower blade piece 10 is combined, the blade 110 is straightened in an upright form without changing the coupling angle. It is also possible to form a combination, except for the shape of the blade 110 is the same as in the twist (twist) form.

Now look at the case of forming the blade segment (110s) with two blade pieces (10) first to find the actual assembly coupling process.

In this case, as shown in the figure, after joining the shaft coupling portions 10A of the two blade pieces 10, the blades are firmly coupled to the assembling grooves 10h formed in each of the two blade pieces 10 by means of screws or the like. Segments 110s are formed. The blade segment 110s can be formed by inserting the blade segments 110s formed in the shaft shaft 130 one by one, and the booster 120 is naturally formed in this process.

When inserting the blade segment 110s into the shaft shaft 130, it is important to consider the angle of twist between each blade segment 110s in consideration of the wind power generation.
