The present invention relates to a windmill for a wind turbine, and more particularly, to provide a windmill consisting of a single frame including a wing, that is, a block-shaped frame, and multi-stacked each other irrespective of the height of the wind. It is possible to continuously produce electricity while preventing the load of the rotating shaft rotated by the blades.In case of failure of multi-stage stacked windmills, the power of the blades and the rotating shaft forming the windmill can be cut off to prevent unnecessary waste of energy for power generation. The present invention relates to a windmill for a wind turbine.

In general, the wind power generator is an apparatus capable of generating power using the wind, which is a clean energy source for uninterrupted use, and has a cost aspect such as improving the price competitiveness of the power generation unit cost by each power source and minimizing the required area of the power generation system, and fossils. It is accelerating its spread because it provides economic and social aspects such as alternative energy sources and environmental protection for energy depletion, as well as economic stability such as supply stability and reduced dependence on energy imports.

The wind turbine is composed of a wing for converting the external wind into rotational energy, a tower for positioning the wing at a constant ground level, and a generator installed at the top or the bottom of the tower. Can be classified as

However, as described above, the wind power generator having horizontal and vertical axes is installed with a large power generator to obtain a large amount of wind energy. Therefore, as the size of the power generator increases, the length and weight of the wings increase, resulting in a large production cost. It is consumed and manufacturing is difficult due to the increase of the mechanical dead zone due to low speed rotation. In particular, such a wind power generator, power generation efficiency is high only in the region where the amount of wind and high wind speed is high, the power generation efficiency is reduced in narrow places where the amount of wind is low and the wind speed is low.

On the other hand, the wind turbine having a vertical axis as described above is provided with a wing of a long form from the upper region to the lower region of the vertical axis, and thus rotates to the wing of the lower region without wind only by wind blowing in the upper region. Since a lot of loads are generated on the blades, a loss of energy driving the blades occurs, resulting in an inefficient power generation.

In particular, windmills with one vertical axis and a single long wing along its vertical direction, or windmills with multiple wings mounted on one vertical axis along the longitudinal direction of the vertical axis, If a failure occurs in the rotating wing and the wing assembly assembling the wing has a very big disadvantage to stop the rotation of one vertical axis for troubleshooting and to stop the power production until the repair is completed.

Accordingly, an object of the present invention is to provide a windmill composed of a single frame, that is, a block-shaped frame, which includes a wing that can be rotated by wind power, and the wind is blown by stacking the windmill in multiple stages along the axial direction. It is possible to continuously produce electric power regardless of the position of high and low, and according to islands where population is decreasing, electric power production can be added or subtracted according to the households. If any one or more of the multi-stacked block-type windmills fail, wind power generation can be efficiently produced by cutting off the power of the windmill's blades and the rotating shaft to cut off unnecessary energy. It is to provide a windmill for use.

According to the present invention, in the wind turbine for wind power generators, upper and lower predetermined areas are recessed to a predetermined depth from the surface toward the inner side so that a shaft hole is formed therein, and the upper and lower corners have fixing parts at least. A frame formed in an open shape; A rotating shaft having an upper arm and a male joint in a lower region, formed in a predetermined length, inserted into the shaft hole, and having a reverse rotation preventing member fixed to a predetermined region along a length direction; Wind turbines comprising a wing assembly installed on one side to rotate the rotary shaft by the interference, or to rotate from the rotary shaft by the interference by the interference in accordance with the rotation direction by the wind and the rotation shaft Is achieved by windmills.

Here, the reverse rotation prevention member preferably comprises a ratchet wheel fixed to the central station in the longitudinal direction of the rotary shaft, and a reverse rotation stopper and a spring mounted inside the wing assembly to interfere with the ratchet wheel. .

The reverse rotation prevention member may further include a reverse rotation prevention bearing arranged on any one of the rotation shaft and the wing assembly.

On the other hand, the individual of the windmill for the wind turbine is an object of at least one or more wind turbine for the wind turbine having the same configuration and the stacked wind turbine generator for the multi-stage stacked each of the fixing portion formed in each corner of the frame It is preferable to fix and stack without flow.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

1 is an overall perspective view of a windmill for a wind turbine according to the present invention, Figure 2 is a longitudinal cross-sectional view illustrating a laminated state of the windmill for a wind turbine according to FIG.

As can be seen in these figures, the windmill 10 for a wind power generator according to the present invention is installed on the rotating shaft 20, the frame 30 supporting the rotating shaft, and the rotating shaft 20, and the rotating shaft is formed by wind power. The blade 40 which rotates, and the wing assembly 41 for assembling the rotary shaft 20 and the blade 40 is equipped with a reverse rotation prevention member 60 for intermittent rotation of the rotary shaft.

In the central regions of the upper and lower sides of the frame 30 formed in an open shape, assembling parts 31 and 33 recessed inwardly are formed, and bottoms of the assembling parts 31 and 33 are formed. On the surface, the shaft holes 35 and 37 having a penetrating shape are formed through the bearing 36, while the upper and lower corners of the frame 30 are fixed to each other when the frames 30 are stacked in multiple stages. The fixing part 39 for this is formed.

Here, the shape of the member constituting the frame 30 is not a big problem, and if the structure that can support the rotary shaft 20 and can be laminated in multiple stages, the size and shape may be variously modified, but blown from all directions It is essential that all sides be open to receive the wind.

The female joint 21 is formed in the upper region of the rotary shaft 20 and the male joint 23 is formed in the lower region, and the length thereof is formed in the shaft holes 35 and 37 formed on the upper and lower portions of the frame 30. It is formed to a length that can be inserted and stacked.

On the other hand, Figure 3 is a longitudinal cross-sectional view showing the internal configuration of the reverse rotation prevention member according to the invention, Figure 4 is a cross-sectional view according to FIG.

As can be seen in these figures, each rotation shaft 20, 20a, 20b according to the present invention, the anti-rotation member 60 is fixed, where the anti-rotation member 60 is a wing by the wind According to the rotational direction of the 40, any one of the windmills 10 (multi-layer stacked in a block form by rotating the rotating shafts 20, 20a and 20b or idling from the rotating shafts 20, 20a and 20b) ( When an abnormality occurs in the blade installed in the 10a) (10b) is to prevent the blade from rotating in accordance with the rotation of the other rotary shafts (20, 20a, 20b). In other words, the load on the rotating shafts 20, 20a and 20b generated by rotating to an unnecessary portion is reduced.

Such a rotation preventing member 60 may be configured in various ways, in the embodiment according to the present invention, the ratchet wheel 61 is fixed to the central station in the longitudinal direction of the rotation shaft 20, the wing assembly 41 It consists of a reverse rotation stopper 63 to interfere with the rotation of the ratchet wheel (61) and a spring (65) to elastically support it. However, the reverse rotation preventing member 60 except for the configuration of the ratchet wheel 61, and the anti-rotation stop 63 and the spring 65 to interfere with the ratchet wheel 61 in the wing assembly 41. , Anti-rotation bearing (not shown) is installed in any one of the rotating shaft 20 and the wing assembly 41 to prevent the rotation of the blade can be obtained because the reverse rotation prevention effect according to the present invention can be obtained. .

5 is an exemplary view for explaining the operating state of the windmill for the wind power generator according to the present invention, the windmill 10, 10a, 10b in this figure is stacked in a multi-stage in places where the yearly average wind is high The gearbox 70 and the generator 80 which speed up the rotating shaft 20, 20a, 20b which rotate by the blades 40, 40a, 40b are attached to the area | region.

The stacking degree of the windmill 10 according to the present invention configured as described above may vary the number of stacking of each windmill 10, 10a, 10b according to the required power consumption in proportion to the wind volume, wind speed, and household number of the region. There will be. In other words, if there is a large amount of wind in the high place of the year it is desirable to stack a high number of windmills (10), which is a block-shaped individual, and if the area is a lot of wind, even in low places by stacking a small number of windmills (10) Also, the number of households can be changed by stacking a large number of stacked windmills 10, and when the number of households decreases, reducing the number of some of the stacked windmills 10 to lower the power production. Here, the frame 30 constituting the windmill 10 may be firmly fixed to the fixing portion 39 formed at each corner without flow by a bolt (not shown).

On the other hand, the windmill 10 is stacked in multiple stages so as to transmit the mutual rotational force by the arm, the water joint 21, 23, respectively installed on the rotary shaft 20 when a predetermined number is stacked in a state maintaining a constant height , If the wind blows from the full height portion of the stack of windmills 10, 10a and 10b, all the wings 40, 40a and 40b of each of the windmills 10, 10a and 10b stacked in multiple stages. Is rotated in one direction, for example clockwise to rotate each of the rotary shafts 20, 20a (20b) to drive the gearbox 70 and the generator 80 installed in the lower region to produce power.

However, for example, if the wind is blowing in a certain direction only in the B1 position of FIG. 5, the reversing stopper 63 installed in the wing assembly 41 assembled with the wings 40 in the frame 30 existing at the corresponding position is a rotating shaft. Interfering with the ratchet wheel (61) installed in the (20) to rotate the rotary shaft 20, which is the corresponding rotary shaft 20 to rotate the rotary shaft (20a) located directly below the connection with the male joint (23) By repeating the rotation of the rotating shaft 20b of the frame 30a located at the bottom.

Here, the rotary shafts 20a and 20b rotate only their rotary shafts 20a and 20b, but the blades 40a and 40b provided on the rotary shafts 20a and 20b do not rotate because there is no wind. Each wing 40a, 40b installed in the blade 20b and the wing assemblies 41a and 41b connected thereto are not rotated so that the rotating shafts 20, 20a and 20b rotate to the blades 40a and 40b. No power is required to rotate until the load is reduced, effectively producing power.

In addition, if the wind is blowing in a certain direction only in the B2 position of FIG. 5, the reversing stopper 63 installed in the wing assembly 41b assembled with the wings 40b in the frame 30b existing at the corresponding position is a rotating shaft ( The rotating shaft 20b is rotated by interfering with the ratchet wheel 61 installed in the 20b, and in this case, the corresponding rotating shaft 20b is repeated by rotating the rotating shaft 20a positioned at the upper part connected to the arm joint 21. Rotate the rotating shaft 20 of the frame 30 located at the top.

However, even in this case, only the rotary shafts 20b, 20a and 20 rotate only the rotary shafts 20b, 20a and 20, and the blades 40a and 40 provided on the rotary shafts 20b, 20a and 20 Since there is no wind and does not rotate, the respective blades 40a and 40 and the wing assemblies 41a and 410 connected to each of the rotor shafts 20a and 20 are not rotated so that the rotor shafts 20b and 20a rotate. 20 is unnecessary power to rotate the blades (40a, 40) to reduce the load, while each of the rotary shafts installed in each windmill 10 is accelerated rotation in the clockwise direction is rotated, so that the rotary shaft is rotated The rotational force is increased by the 70 to generate alternating current by operating the generator 80.

On the other hand, if the wing or wing assembly installed in any one of the stacked windmills 10, 10a and 10b is not able to play a role due to an abnormality, the rotating shaft rotates while repairing the corresponding blade, thus failing. Even during this repair, the power can be produced continuously.

In the above description and the embodiment, since the present invention is merely a description of the preferred embodiment, the scope of application of the present invention is not limited to the windmill of the form and shape as shown in the above-described embodiment. The structure and shape of the stackable frame and arm, the rotating shaft having a male joint, and the shape and shape of the element deformed from the shape and shape of the windmill installed on any one of the rotating shaft and the wing assembly to interfere the direction of rotation of the wing If it is a change, the windmill of any shape and form is possible for implementation of this invention, of course, it is included in the technical scope of this invention.

As described above, the windmill for the wind power generator according to the present invention has the advantage that it is possible to effectively perform the power production even if the location of the wind speed and the direction of the wind direction is uneven, and also to increase or decrease the power production as needed. In addition, since the structure of the windmill is relatively simple, it is easy to move the site, and the windmill for the wind power generator can be economically produced by reducing the consumption of unnecessary energy for power generation.
