Such a structure is exemplarily illustrated in FIG. 3A, and is fixedly installed using a separate fixing means (not shown) in the middle of a sidewall of a structure B such as a building.

The collection port 110 is connected to the pipeline 120 for moving the wind up to the upper side, such a pipeline 120, for example, to the upper side along the wall of the structure (B), such as a building It is installed to extend, in the middle of the heating unit 130 is installed to increase the wind passing through the interior of the pipeline (120).

As shown in FIG. 2, the heating unit 130 may be configured as a solar heater 132 configured to collect solar heat to heat the wind of the pipeline 120 to increase the temperature. In this case, the pipeline 120 may be formed in a passage through which an interior is formed, and a space for condensing and heating the solar light is formed outside the pipeline 120.

Such a solar heater 132 is configured to form a vacuum between the inner tube (134) and the outer side (out side tube) 136 to achieve the function of heat shielding to the outside, the internal absorbent coating layer (selective) The coating induces the absorption of heat, and the heat absorbed in this way is collected to heat up the wind passing through the pipeline 120.

In addition, such a solar heater 132 is preferably disposed perpendicular to the sun light, in general, in the northern hemisphere, it is suitable to install at an angle θ of about 37 degrees to the ground by applying the latitude of the area.

In addition, the noise reduction wind turbine generator 100 according to the present invention includes a vibration generator 150 having a blade 154 mounted at an outlet of the pipeline 120 and vibrating by wind. The vibration generator 150 includes a housing 152 made of a low noise material, and the blade 154 vibrates by the wind in the housing 152.

The vibration generating unit 150 is installed on the roof of the structure (B), for example, as shown in Figure 3b, to form a height difference (Δh) with respect to the collecting port 110 In this way, the wind speed is increased while the wind is moving through the pipe line 120 provided to have the height difference Δh, and the wind is heated by the heating unit 130 to further increase the wind speed in the housing. It flows into the inside of 152.

The structure of the vibration generating unit 150 is shown by way of example in FIG.

The vibration generating unit 150 has an inlet 162 connected to the outlet of the pipeline 120, and has an outlet 164 formed coaxially from the inlet 162. In addition, the middle portion of the housing 152 extending from the inlet 162 to the outlet 164 forms a diameter expanding portion 166 having a larger inner diameter than the inlet to allow the wind to pass through the passage having an increased area.

In addition, the vibration generator 150 has a low noise structure in which the housing 152 incorporates a sound absorbing material, for example, a sound absorbing material such as Styrofoam, and has a rotation shaft 168 at the center of the diameter expanding part 166. Through the end of the blade 154 is fixed, the tip 154a of the blade 154 extends toward the inlet side to divide the wind passing through the inlet 162 to both sides.

Such a blade 154 has a tip 154a having a pointed cross section to minimize the resistance caused by wind passing through the inlet, such blade 154 has both sides generated by the wind passing through both sides thereof. Due to the pressure difference on the surface, the vibration is caused about the rotation axis 168.

That is, in the process of passing through both sides of the blade 154, the wind is formed a speed difference, since the pressure is lower than the side of the wind speed is relatively slow side, the blade 154 pressure The tip 154a impinges on the inlet of the housing 152 as it moves downward.

At this time, the housing 152 is provided with shock absorbing pads 170a and 170b on both inner surfaces of the inlet 162 to cushion the impact of the blade 154 at the inlet to prevent noise from occurring. .

And the noise reduction wind power generator 100 according to the present invention has a torque-rotation converter 180 is connected to the rotating shaft 168 of the blade 154.

The torque-rotation converter 180 is disposed adjacent to the vibration generating unit 150 and through the frame 182 and the arc-shaped links 184a and 184b by the vibration transmitted from the blade 154. The torque is converted into rotational force and output.

As shown in FIGS. 5A and 5B, the torque-rotation converter 180 includes a “T” -shaped frame 182 therein and is translated by the frame 182 to output the output shaft 188. ) Is provided with a plurality of arc-shaped links (184a, 184b) for continuous rotation.

That is, the “T” frame 182 has one end thereof connected to the rotating shaft 168 of the blade 154 so that the left and right sides are seesawed by the vibration of the blade 154, and the frame 182 The other end is rotatably connected to one end of the plurality of arc-shaped links 184a and 184b.

The other end of each arc-shaped link 184a and 184b is rotatably connected to the output shaft 188, and the plurality of arc-shaped links 184a and 184b to each other above and below the output shaft 188. It is a structure arranged oppositely.

This torque-rotation converter 180 outputs the plurality of arc-shaped links 184a and 184b while the " T " frame 182 moves from left to right, as shown in FIG. 6A. Rotate axis 188 clockwise. At this time, the upper arc-shaped link 184a rotates the output shaft 188 in the clockwise direction, but the lower arc-shaped link 184b is not idling to impart rotational force to the output shaft 188.

Also, as shown in FIG. 6B, the output shaft 188 is rotated clockwise through the plurality of arc-shaped links 184a and 184b while the “T” shaped frame 182 moves from right to left. . At this time, the upper arc-shaped link 184a idles the output shaft 188, and the lower arc-shaped link 184b rotates the output shaft 188 clockwise.

The output shaft 188 has a built-in one-way device (not shown) which rotates the output shaft 188 only in the clockwise direction, so that the blade 154 may be operated again after the wind or wind is not working. The axis 188 is always characterized by being rotated only in one direction, for example clockwise.

Therefore, such torque-rotation converter 180 is output through the "T" -shaped frame 182 and the plurality of arc-shaped links 184a, 184b by the vibration of the rotating shaft 168 transmitted from the blade 154. The shaft 188 is rotated continuously in one direction, for example clockwise.

Noise reduction type wind power generator 100 according to the present invention is a rotor (not shown) is connected to the output shaft 188 of the torque-rotation converter 180 is rotated by a stator (stator ( And a rotary power generation unit 190 for generating power and storing the generated power in the storage battery 200.

The rotary power generation unit 190 is a generator incorporating a rotor (not shown) and a stator (not shown) made of a conventional permanent magnet. As shown in FIGS. 1, 2 and 3b, the torque- An internal rotor is connected to the output shaft 188 of the rotation converter 180 to generate power by rotating. In addition, the power thus produced is stored in the storage battery 200, and then supplied to the necessary use.

Noise reduction type wind power generator 100 according to the present invention configured as described above is the collecting port 110 and the heating unit 130 is shown in the lower portion of the structure (B), as shown in Figure 3a, The pipeline 120 extends upward from the collecting port 110 along the structure B. The vibration generating unit 150, the torque-rotating converter 180, and the rotary power generating unit 190 are illustrated in FIG. 2. As shown, it is installed on the upper portion of the structure (B) to form a height difference (Δh) with respect to the collecting port (110).

Therefore, while the wind passes through the pipeline 120, the wind speed is increased by the height difference Δh, the temperature is increased by the heating unit 130, and the wind speed is further increased, so that the blades of the vibration generating unit 150 ( 154 vibrates strongly.

2 is a diagram in which the collecting port 110 is attached to the side of the building, the air moving to the side is collected in the collecting port 110 is raised through a vertically installed pipeline 120 installed in the vibration generating unit Accelerated to 150 to rise. At this time, the relationship between the temperature associated with the air rise is shown in Equation 1 below.

(Equation 1) Vs = [2gHTs (To ^-1- Ts ^-1 )] ^-1/2,

In Equation 1, for example, when the temperature Ts (50 ° C.) in the greenhouse and the external temperature To (20 ° C.), the flow velocity from the pipeline 120 having H = 10m is calculated as follows.

Vs = [2 * 9.8m / s ² * 10m * 323K (293 ^-1- 323 ^-1 )] ^-1/2 = 4.48m / s, and the temperature difference is the same as shown in Table 1 below, and it can be seen that the wind speed changes according to the height change.

 Relationship between height change and wind speed under the same conditions Height (m) Flow rate (m / s) 5 3.18 10 4.48 15 5.49 20 6.33

As another example, as shown in Table 2 below, the wind speed increases according to the height change of the building. As the height of the building increases, the wind speed increases.

 Comparison of wind strength, wind density and wind speed Height 10 m 30 m 50 m rating Wind density

As such, the air collected through the collecting port 110 of FIG. 2 is initially collected at a large area of the inlet at a low speed, and the flow rate increases in inverse proportion to the size of the area, and passes through the pipeline 120. While passing through the temperature 130, the temperature is increased to flow into the inlet of the housing 152 in which the blade 154 of the vibration generator 150 is mounted.

In this case, in the present invention, even in the case of a low wind speed of about 0.5-1.0 m / s in the collecting port 110, the height difference (Δh) of the pipeline 120 is raised through the temperature raising operation of the heating unit 130. In this case, the vibration generating unit 150 has a high flow rate of 2-3 times at an accelerated wind speed of 2.5-3.5 m / s sufficient for power generation, thereby vibrating the blade 154 strongly.

Table 3 below shows the wind speed of the collecting port 110 obtained by the experiment and the experimental wind speed (m / s) in the housing 152 of the vibration generating unit 150.

Changes in size and final flow rate of collecting port (installed on the side of building, position above ground: 10m) Wind speed of collecting port (m / s) Wind velocity at housing inlet (m / s)  50cm * 160cm 0.8 2.4  50cm * 300cm 0.6 3.5

On the other hand, the present invention is not limited to the above-described embodiment, the scope of application is various, such as the upper floor of the building, transmission tower, cliff, etc., in particular, in the case of installing the collecting port 110 in the roof of the top of the building long Larger winds can be obtained, which can be confirmed by looking at the example of building winds reported in Table 4 below.

Types of Building Winds and Their Velocity (Area: Near Samseong-dong, Seoul) When to measure Measuring height (m) Average maximum speed wind speed (m / s)  March-November           60 19.2

Figures 7a and 7b shows a map of the content of the building wind generating area and the magnitude of the flow rate and flow rate, it can be seen that the largest wind energy is integrated in the upper part of the building, it can be seen that very large power generation is possible using this Can be.

That is, as shown in FIG. 7A, the wind energy is not concentrated in the general sub-center 220 without the high-rise building, but as shown in FIG. 7B, in the city center 230 in which the high-rise building is erected, near the upper rooftop of the building and the building. It can be seen that wind energy is concentrated on the side.

Therefore, if the collecting port 110 is installed in such a portion, it is preferable to obtain a high wind speed naturally.

Table 5 below is a table comparing the wind speed according to the roof type. As can be seen from Table 5, a wind speed sufficient for power generation can be obtained near a building height of 50 m.

Comparison of wind speeds formed around buildings (building height 50m) Roof type Slab type Sloped Roof (26 ^o ) Wind speed (m / s) 9.7 11.3 Estimated Power Production (Kw) 5.3 6.0

As described above, when the wind speed rises from the collecting port 110 to the vibration generating unit 150 via the pipeline 120, the vibration generating unit 150 has a blade 154 installed in the housing 152. ) Vibrates, and the torque obtained by the vibration force is changed to the rotational force by the torque-rotation converter provided on the left side of the housing 152, and is generated through the rotary power generation unit 190 by this rotational force.

At this time, the noise during vibration caused by the blade 154 itself of the vibration generating unit 150 is externally absorbed by the sound absorbing effect of the housing 152 material and the buffer pads 170a and 170b mounted at the inlet. The furnace emits little noise due to vibration energy.

As described above, the present invention has various advantages as described above, and thus, unlike the existing wind generator, low noise performance and stability are ensured, so that the present invention can be installed and installed in various urban facilities and buildings. In particular, there is no fear of serious structural damage that may be caused by the resonance caused by the vibration energy generated in the existing wind generator is more advantageous.

As described above, the noise reduction wind generator of the present invention collects wind through the collecting port 110 and accelerates the wind speed through the pipeline 120 and the heating unit 130 to induce an increase in the wind speed. The air flow accelerated and raised in this way vibrates the blade 154 of the vibration generator 150 installed at the end of the pipeline 120 which is the fluid passage.

At this time, the accelerated fluid flows on both sides of the blade 154 installed in the housing 152, and the blade 154 vibrates by the pressure difference generated at both surfaces, and the vibrating force is torqued through the rotation shaft 168. -The " T " frame 182 of the rotation conversion unit 180 is actuated to apply torque to the output shaft 188, and the rotor of the rotary power generation unit 190 is operated to generate power.

As such, the present invention has the advantage of being able to generate at a lower wind speed than the movable wind speed of a vertical wind generator known to be able to generate power even at a low speed. It can be seen that safety is guaranteed.

Therefore, the present invention, unlike the existing wind generators, it ensures low noise performance and stability, it is possible to generate power by installing in various urban facilities and buildings.

As described above, the present invention increases the inlet wind power of the collecting port 110 at a high wind speed of 2-3 times while moving the pipeline 120 even at a very low wind speed of 0.5 to 1.0 m / s. Start-up and power generation can be made, and when installed in a structure (B), such as a building having a height of 40-50m with a building wind, transmission tower, high-voltage wire tower, it can obtain an excellent power generation effect.

 In addition, according to the present invention, the blade 154 in the housing 152 made of a low noise material vibrates by the increased wind speed, thereby converting torque into a rotational force through the torque-rotation converter 180, thereby operating at low noise during power generation. Even under high speed wind, there is no fear of damage to the propeller or the like as in the prior art.

In addition, according to the present invention, it is possible to generate power by collecting wind blowing in caves and canyons in addition to other urban areas, and is installed in most areas and buildings, and has excellent advantages in generating electricity stably.
