First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that a detailed description of a related known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the configuration of a wind power tower according to the present invention, Figure 2 is a view showing a cross-sectional view of the wind power tower according to the present invention.

As shown in Figures 1 to 2, the wind power tower according to the present invention, by accelerating the wind effectively by using the air differential pressure generation phenomenon to accelerate the wind, by adjusting the inflow angle of the wind is the area where the wind flows Allow for maximum growth.

To implement this, the wind power tower is configured to include a ventilation tower 100, the guide wall 200, the rotary blade 300, the direction indicating stopper 400 and the wind rotor 500.

Ventilation tower 100 is a tower-shaped structure in which wind passages 110 through which wind flows are formed in a plurality of layers, and an internal structure in which wind converges to the center by using guide walls 200 and rotating blades 300. Has a, through the wind rotor 500 installed in each layer to ensure that independent power generation is made in that layer.

The guide wall 200 is disposed radially from the center of the ventilation tower 100 to form a flow path through which the wind is moved so that the wind introduced into the ventilation tower 100 is concentrated toward the center of the ventilation tower 100. . Therefore, when the wind flowing into the wind hole 110 is concentrated by the guide wall 200 to the center of the ventilation tower 100, the introduced internal air generates an air differential between the outside air, the air differential pressure of the wind You can increase the speed.

The rotating blade 300 adjusts the angle of the wind moved by the guide wall 200, so that the wind inflow area is increased to the maximum when the wind rotor 500 flows. As a result, in the wind rotor 500, the maximum wind inflow area may be secured regardless of the direction in which the wind blows, and, thus, maximization of power generation efficiency may be realized.

Directional stopper 400 serves to limit the rotation of the rotary blade 300 to a predetermined angle, preferably the rotation of the rotary blade 300 is made within the angle between the outer and inner circumference of the rotor blade 530 Restrict to lose. Here, specific details for limiting the rotation of the rotary blade 300 will be described later.

The wind rotor 500 is a device that implements electricity generation by using wind moved to the center of the ventilation tower 100. Since the wind rotor 500 is disposed at the center of each floor of the ventilation tower 100 so as to be positioned in a straight line with respect to the wind passage 110 through which the wind is introduced, the direction of the wind is changed several times until it is moved to the generator 540. It is possible to prevent the wind energy loss problem of the prior art caused.

In order to more clearly describe the above-described configuration, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

Referring back to Figures 2 and 2, the ventilation tower 100 according to the present embodiment is a cross-sectional quadrangular tower of the cross-sectional shape, each floor is provided with a wind speed sensor for measuring the speed of the wind.

In addition, eight partition spaces radially partitioned are formed in each floor of the ventilation tower 100. Wind is introduced into two or three adjacent compartments of the eight compartments, and the winds introduced into these compartments converge toward the center of the ventilation tower 100 to increase the wind speed. These compartments are partitioned by the guide wall 200.

Guide wall 200 is a structure that is deployed in a radial form from the center of the ventilation tower 100 in order to guide the wind introduced through the wind hole 110 to the center of the ventilation tower (100).

Here, if the guide wall 200 extends a certain length, the amount of wind flowing through the wind hole 110 may be increased, and the speed of the wind flowing into the center of the ventilation tower 100 may also be increased. . However, the length of the guide wall 200 should be determined in consideration of design factors such as the frictional resistance of the guide wall 200 and the surrounding environment.

The guide wall 200 is composed of a guide vertical wall 210, guide horizontal wall 230 and guide slope wall 220. The guide vertical wall 210 constitutes a sidewall of the ventilation tower 100, but is disposed radially from the ventilation tower 100, and the guide horizontal wall 230 is disposed perpendicular to the guide vertical wall 210 to provide a ventilation tower 100. Each layer of), and the guide slope wall 220 is inclinedly connected to the guide horizontal wall 230 so that the wind converges toward the rotor blade 530 of the wind rotor 500.

At this time, the guide slope wall 220 of the guide wall 200 is disposed inclined upward toward the center of the ventilation tower 100, for example, the rotor blade 530 of the wind rotor 500, the generator 540 in the lower side The installation space of can be prepared. And the guide vertical wall 210 is preferably composed of a plurality of radially arranged in an angle range within 30 degrees, in this embodiment, the guide vertical wall 210 is disposed in a radial form at intervals of 22.5 degrees, thereby providing a ventilation tower ( The interior of 100) was divided into eight compartments. In addition, the rotating blade 300 is rotatably connected to the inner end of the guide wall 200.

The rotary blade 300 is connected to the inner end of the guide wall 200 and the rotation shaft 301 so as to allow free rotation at the inner end of the guide wall 200, and one side and the other side thereof move from the guide wall 200. It is a structure that can be rotated in one direction or the other direction by the wind pressure of the wind.

Figure 3a is a view showing a state in which wind is introduced from the wind power tower when the rotating blade is rotated in accordance with the present invention, Figure 3b is assuming that the rotating blade is fixed compared to the case where the rotating blade is rotated wind power A state diagram showing the flow of wind from the power generation tower.

In particular, as shown in Figure 3a, the rotary blade 300 adjusts the angle of the wind so that the maximum wind inlet area flowing into the wind rotor 500 is maximized. To this end, the rotation angle α of the rotary blade 300 is a vertical tangent T1 in which the inner circumference of the rotor blade 530 is perpendicular to the inner end of the guide wall 200, and the outside of the rotor blade 530. The circumference should satisfy the angular range between the vertical tangent T2 which is in perpendicular contact with the inner end of the guide wall 200. Vertical tangents T1 and T2 in the figure are indicated by dashed lines.

That is, when the rotary blade 300 is rotated due to the inflow of wind, the rotary blade 300 of one side is disposed on the vertical tangent (T2) in contact with the outer circumference of the rotor blade 530 and the rotary blade 300 of the other side Is disposed at the vertical tangent T1 ′ and the vertical tangent T1 ″ in contact with the inner circumference of the rotor blade 530. At this time, the wind inflow area for rotating the rotor blade 530 is as shown in FIG. It is represented by the combined area of S2.

On the other hand, as shown in FIG. 3B, when the rotating blade 300 'is fixed despite the inflow of wind, the rotating blade 300' is disposed at a vertical tangent tangent to the inner circumference of the rotor blade 530. Therefore, the wind inflow area S for rotating the rotor blade 530 is represented by the area of S1 as shown in FIG. 3B.

As such, when the rotation blade 300 is rotated within a predetermined angle, the wind inflow area may be increased to the maximum even if the wind has the same speed as when the rotation blade 300 is fixed. As a result of the experiment, the rotation blade 300 rotates within a predetermined angle, the wind inflow area is increased by about 30% than when the rotation blade 300 is fixed, regardless of the direction of the wind blowing. Maximum wind inflow area could be secured.

The rotation angle of the rotary blade 300 is limited through the direction indicator stopper 400.

Direction indicator stopper 400 is composed of a pair of spaced apart while maintaining a certain distance with one rotating blade 300 in between. The separation distance with respect to the pair of direction indicator stopper 400 is determined by the rotation angle of the rotating blade 300 which can increase the wind inflow area to the maximum.

For example, the direction indicating stopper 400 limits the rotation angle of the rotation blade 300, and the rotation blade 300 limited to the rotation angle maintains the maximum wind inflow area according to the rotation angle at the guide wall 200. Guide the moved wind to the wind rotor (500).

Figure 4 is an enlarged view of the "A" part of Figure 1, Figure 5a is a view showing the configuration of the wind rotor of the wind power tower according to the present invention, Figure 5b is a flat of the wind rotor of the wind power tower according to the present invention It is a figure which shows sectional drawing.

As shown in FIGS. 4-5B, the wind rotor 500 includes a rotating shaft 520, a rotor blade 530, a guide barrel 560, and a generator 540 to produce electricity by using wind. It is configured by.

The rotary shaft 520 is rotated in conjunction with the rotation of the rotor blade 530, is installed in the center of the ventilation tower 100 via the bearing 551, the generator 540 via the rotary gear 541. And drive are connected. Therefore, when the rotor blade 530 is rotated by the flow of wind, the rotating shaft 520 is rotated in conjunction with the rotation of the rotor blade 530, the generator 540 to generate electricity by using the rotational force of the rotating shaft 520. Can be.

The rotor blade 530 is composed of a plurality of spaced apart while surrounding the rotation shaft 520 in a ring shape to provide a rotational force to the rotation shaft 520. In particular, the rotor blade 530 is configured in a semi-cylindrical curved concave toward the direction in which the wind flows in order to maximize the resistance by the wind, preferably the separation angle β between the adjacent rotor blades 530, It satisfies the range of 22 degrees to 23 degrees.

The guide cylinder 560 is configured in the form of a cylindrical pipe surrounding the rotating shaft 520. The guide cylinder 560 prevents the wind moved from the rotor blade 530 to move straight to the opposite rotor blade 530 across the rotation axis 520, thereby smoothly moving the wind from the rotor blade 530. To be guided and moved.

The generator 540 is driven and connected to the rotating shaft 520 through the rotating gear 541 so that electricity can be generated using the rotating force of the rotating shaft 520. The generator 540 according to the present embodiment is the same as the configuration of a conventional generator 540 used for wind power generation, so a detailed description thereof will be omitted.

6 is a view showing a wind rotor configuration of a wind power tower according to a modification of the present invention.

As shown in FIG. 6, the wind rotor 500 may be equipped with an upper magnet support piece 550a and a lower magnet support piece 550b for maintaining the rotor blade 530 at no load. The upper magnet support piece 550a and the lower magnet support piece 550b are made of a magnetic material having the same polarity to each other to realize a magnetic levitation effect using the repulsive force of the magnetic material.

For example, the upper magnet support piece 550a is fixedly installed on the upper end of the rotating shaft 520 via the upper support piece 553a, and the lower magnet support piece 550b has the same polarity as the upper magnet support piece 550a. And it is fixedly installed in the center of the ventilation tower 100 via the lower support piece (553b).

At this time, a guide piece 552 for supporting the upper support piece 553a is provided at the center of the ventilation tower 100 so that the upper magnet support piece 550a and the lower magnet support piece 550b are located at opposite points. do.

The wind rotor 500 is provided with a wind flow path 570 for guiding the movement of the introduced wind. The wind flow path 570 allows the flow of air in the wind rotor 500 to be smooth, so that the rotor blade 530 of the wind rotor 500 can be effectively operated.

Wind flow path 570 to implement this, the first, second, third and fourth

wind flow paths

570a, 570b, 570c, 570d which induce a smooth air flow around the rotor blade 530. Is done.

* The first wind flow path (570a) is formed between the inner end of the rotary blade 300 and the outer periphery of the rotor blade 530, the second wind flow path (570b) of the guide cylinder 560 and the rotor blade 530 The third wind path 570c is formed between the inner circumferences, and the third wind path 570c communicates with upper ends of the first wind path 570a and the second wind path 570b from the upper side of the rotor blade 530, and the fourth wind path 570 The lower portion of the first wind channel 570a and the second wind channel 570b communicate with each other at the lower side of the rotor blade 530.

As such, when the wind flow path 570 is formed around the rotor blade 530, a part of the air introduced into the rotor blade 530 is rotated together with the rotor blade 530 and flows out of the rotor blade 530. In this case, the air flowing out of the rotor blade 530 may be induced to re-enter the rotor blade 530 by the wind flow path 570, whereby the rotational speed of the rotor blade 530 is one layer In addition, the power generation efficiency may be improved by improving torque of the rotor blade 530. In addition, the wind flow path 570 may smoothly discharge the air introduced into the rotor blade 530, so that the air flow into the rotor blade 530 can be made quickly and smoothly.

At this time, the area ratio of the rotor blade 530 and the wind flow path 570 preferably satisfies 3: 7. Because, in order to effectively implement the rotation operation of the rotor blade 530, it is required to obtain the optimum area ratio of the rotor blade 530 and the wind flow path 570, which can smoothly flow the air in the wind rotor 500. In order to obtain this optimum area ratio, the present inventor has undergone numerous trial and error, and as a result, the inventors have found that the configuration of the ratio is most suitable. Therefore, if the ratio is out of the configuration of the air flow in the wind rotor 500, there is a fear that the flow is lowered.

However, since the installation structure of the solar panel is affected by the angle of incidence and the amount of sunshine of the sun, it can be changed depending on the region and the surrounding environment.

Electrical energy generated by the solar cell module 710 is charged through a capacitor.

The capacitor charges the electric energy generated through the solar cell module 710 during the time from the sunrise to the sunset where the solar power is possible, and may use the charged electric energy as necessary. This capacitor is controlled by the solar control panel 720.

The solar control panel 720 is responsible for the overall control necessary for the operation of the solar cell module 710 and the capacitor, and using the electric energy stored in the capacitor as the power required for the operation of the ventilation tower 100, or if necessary It may also be used as an operating power for the plant cultivation facility (800).

Typically, a large number of operating energizers are required to rotate the rotor blade 530 in a stationary state. When the rotor blade 530 is normally operated as in the present invention, it actively responds to a wind condition that changes in real time and has a small speed. Even winds can be applied directly to wind power.

In order to implement this, a wind speed sensor, an air nozzle 630, an air tank 640, and a controller 620 may be installed.

Here, the wind speed sensor is installed on each floor of the ventilation tower 100 to measure the wind speed flowing into the wind rotor 500 in real time. The air nozzle 630 is disposed to face the rotor blade 530 of the wind rotor 500 to inject air toward the wind rotor 500 when an operation signal is applied from the controller 620. The air tank 640 stores the high pressure air and provides the air nozzle 630. If the wind speed measured by the wind speed sensor is below a predetermined speed, the controller 620 may apply an operation signal to the air nozzle 630 to maintain the rotation of the rotor blade 530.
