First, in assigning reference numerals to components in each drawing, it should be noted that the same components have the same reference numerals as much as possible even if they are displayed on other drawings. . Further, in the description of the present invention, when it is determined that a specific description of a related known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted. .
Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view showing a configuration of a wind power generation tower according to the present invention, and FIG. 2 is a plan view showing a flat section of the wind power generation tower according to the present invention.
As shown in FIGS. 1 and 2, the wind power generation tower according to the present invention accelerates the wind by effectively concentrating the wind using the phenomenon of air differential pressure generation, and adjusts the wind inflow angle to adjust the wind inflow. So that the area into which the water flows is maximized.
In order to realize this, the wind power generation tower includes the ventilation tower 100, the guide wall 200, the rotating blade 300, the direction indicating stopper 400, and the wind rotor 500.

The ventilation tower 100 is a tower-shaped structure in which a wind passage 110 through which a wind is circulated forms a plurality of layers, and has an internal structure in which the wind is converged at the center using the guide wall 200 and the rotating blade 300. Then, independent power generation is performed in the corresponding layer by the wind rotor 500 installed in each layer.
The guide wall 200 is arranged in a radial pattern at the center of the ventilation tower 100, and forms a flow path through which the wind moves so that the wind flowing into the ventilation tower 100 is concentrated toward the center of the ventilation tower 100. Therefore, if the wind that has flowed into the wind passage 110 is concentrated at the center of the ventilation tower 100 by the guide wall 200, the flow of the internal air that is generated generates an air differential pressure between the external air. Can be increased.
The rotating blade 300 adjusts the angle of the wind moved by the guide wall 200 so that the wind inflow area is maximized when the wind wind rotor 500 enters. Thereby, in the wind rotor 500, the maximum wind inflow area can be ensured irrespective of the direction in which the wind blows, and the maximization of the power generation efficiency can be realized after all.

The direction indicating stopper 400 serves to limit the rotation of the rotary blade 300 to a certain angle, but preferably limits the rotation of the rotary blade 300 within an angle between the outer peripheral edge and the inner peripheral edge of the rotor blade 530. . Here, specific contents for limiting the rotation of the rotary blade 300 will be described later.
The wind rotor 500 is a device that realizes electric power generation using the wind moved to the center of the ventilation tower 100. Since the wind rotor 500 is arranged at the center of each layer of the ventilation tower 100 so as to be positioned in a straight line with respect to the wind inlet 110 through which the wind flows, there are various wind directions until the wind rotor 500 moves to the generator 540. It is possible to prevent the wind energy loss problem of the prior art, which has been caused instead.

In order to clarify the configuration described above, the configuration of the present invention will be described in detail with reference to the drawings as follows.
Referring to FIGS. 1 and 2 again, the ventilation tower 100 according to the present embodiment includes a multi-layer tower having a square cross section, and each layer is provided with a wind speed sensor for measuring the wind speed. It is done.
And in each layer of the ventilation tower 100, eight division spaces divided radially are formed. Wind flows into two to three adjacent partition spaces among these eight partition spaces, and the wind speed increases while the wind flowing into these partition spaces converges toward the center of the ventilation tower 100. The These partition spaces are partitioned by the guide wall 200.
The 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 that has flowed in through the window passage 110 to the center of the ventilation tower 100.

Here, if the guide wall 200 can be extended by a certain length, the amount of wind that flows through the wind passage 110 can be increased, and the speed of the wind that flows into the center of the ventilation tower 100 can also be increased. be able to. However, the length of the guide wall 200 must 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 includes a guide vertical wall 210, a guide horizontal wall 230, and a guide inclined wall 220. The guide vertical wall 210 constitutes a side wall of the ventilation tower 100 and is arranged radially in the ventilation tower 100. The guide horizontal wall 230 is arranged perpendicular to the guide vertical wall 210 to partition each layer of the ventilation tower 100. The inclined guide wall 220 is 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 inclined wall 220 of the guide wall 200 is disposed so as to be inclined upward toward the center of the ventilation tower 100, for example, the rotor blade 530 of the wind rotor 500, so that the generator 540 is installed on the lower side. A space can be provided. The guide vertical wall 210 is preferably composed of a plurality of radial arrangements within an angle range of 30 degrees. In this embodiment, the guide vertical walls 210 are arranged in a radial form with an interval of 22.5 degrees. As a result, the interior of the ventilation tower 100 is divided into eight compartment spaces. A rotating blade 300 is rotatably connected to the inner end of the guide wall 200.
The rotating blade 300 is coupled to the inner end of the guide wall 200 via the rotation shaft 301 so that the inner end of the guide wall 200 can freely rotate, and the one surface and the other surface of the rotating blade 300 move from the guide wall 200. The structure can be rotated in one direction or the other by wind pressure.

FIG. 3a is a view showing a state where wind flows in a wind power generation tower when the rotating blade rotates according to the present invention, and FIG. 3b is a case where the rotating blade is fixed as compared with the case where the rotating blade rotates. It is the state figure which showed the state in which a wind flows in in a wind power generation tower supposing the case.
In particular, as shown in FIG. 3a, the rotating blade 300 adjusts the angle of the wind so that the inflow area of the wind flowing into the wind rotor 500 increases to the maximum. For this reason, the rotation angle α of the rotary blade 300 is such that the inner peripheral edge of the rotor blade 530 is perpendicular to the inner end of the guide wall 200 and the outer peripheral edge of the rotor blade 530 is perpendicular to the inner end of the guide wall 200. The angle range between the vertical tangent lines T2 tangent to must be satisfied. In the figure, vertical tangents T1 and T2 are indicated by dotted lines.

That is, when the rotating blade 300 rotates due to the inflow of wind, the rotating blade 300 on one side is arranged at a vertical tangent line T2 that is in contact with the outer peripheral edge of the rotor blade 530, and the rotating blade 300 on the other side is located inside the rotor blade 530. Arranged at the vertical tangent line T1 ′ and the vertical tangent line T1 ″ in contact with the peripheral edge. At this time, the inflow area of the wind for rotating the rotor blade 530 is indicated by the combined area of S1 and S2, as shown in FIG.
On the other hand, as shown in FIG. 3 b, when the rotating blade 300 ′ is fixed despite the inflow of wind, the rotating blade 300 ′ is disposed on a vertical tangent line that is in contact with the inner periphery of the rotor blade 530. The wind inflow area S for rotating the blade 530 is indicated by the area of S1 as shown in FIG. 3b.
As described above, when the rotating blade 300 is rotated within a certain angle, the wind inflow area can be increased to the maximum even when the wind has the same speed than when the rotating blade 300 ′ is fixed. As a result of the experiment, it can be seen that when the rotating blade 300 is rotated within a certain angle, the inflow area of the wind is increased by about 30% as compared with the case where the rotating blade 300 ′ is fixed, regardless of the direction in which the wind blows. The maximum wind inflow area could be secured.

The rotation angle of the rotating blade 300 is limited by the direction indicating stopper 400.
The direction indicating stopper 400 is configured as a pair that is spaced apart from each other with a single rotating blade 300 interposed therebetween. The separation distance between the pair of direction indicating stoppers 400 is determined by the rotation angle of the rotary blade 300 that can increase the wind inflow area to the maximum.
For example, the direction indicating stopper 400 restricts the rotation angle of the rotating blade 300, and the rotating blade 300 with the restricted rotation angle keeps the wind inflow area from being maximized by the corresponding rotation angle. Is guided to the wind rotor 500.
4 is an enlarged view of part A of FIG. 1, FIG. 5a is a view showing the structure of the wind rotor of the wind power tower according to the present invention, and FIG. 5b is a view of the wind rotor of the wind power tower according to the present invention. It is drawing which showed the plane cross section.

As shown in FIGS. 4 to 5b, the wind rotor 500 includes a rotating shaft 520, a rotor blade 530, a guide cylinder 560, and a generator 540 in order to produce electricity using wind.
The rotation shaft 520 is structured to rotate in conjunction with the rotation of the rotor blade 530, and is installed at the center of the ventilation tower 100 with a bearing 551 as a medium, and is drivingly connected to the generator 540 with the rotation gear 541 as a medium. Therefore, if the rotor blade 530 rotates due to the flow of wind, the rotating shaft 520 rotates in conjunction with the rotation of the rotor blade 530, and the generator 540 can produce electricity using the rotational force of the rotating shaft 520. it can.
The rotor blade 530 includes a plurality of rotor blades 530 spaced apart from each other around the rotation shaft 520 so as to provide a rotational force to the rotation shaft 520. In particular, the rotor blade 530 is formed in a semi-cylindrical shape that is concave and curved in the direction in which the wind flows in order to maximize the resistance caused by the wind, and the separation angle β between the adjacent rotor blades 530 is preferably 22 Satisfies the range of degrees to 23 degrees.

The guide cylinder 560 is configured in the form of a cylindrical pipe that surrounds the rotating shaft 520. Such a guide tube 560 prevents the wind moved from the rotor blade 530 from moving straight to the rotor blade 530 on the opposite side across the rotation shaft 520, thereby smoothly guiding the wind moved from the rotor blade 530. Can be moved.
The generator 540 is drivingly 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. Since the generator 540 according to the present embodiment has the same configuration as that of a normal generator 540 used for wind power generation, a detailed description thereof will be omitted.

FIG. 6 is a view showing a wind rotor configuration of a wind power generation tower according to a modification of the present invention.
As illustrated in FIG. 6, the upper rotor 550 a and the lower magnet support 550 b for maintaining the rotor blade 530 in an unloaded state may be attached to the window rotor 500. The upper magnet support piece 550a and the lower magnet support piece 550b are made of magnetic materials having the same polarity, and 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 through the upper support piece 553a, and the lower magnet support piece 550b is configured with the same polarity as the upper magnet support piece 550a, and the lower support piece 553b. Is fixedly installed in the center of the ventilation tower 100.

At this time, a guide piece 552 for supporting the upper support piece 553a is provided at the central portion 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.
The wind rotor 500 is formed with a window flow path 570 that guides the movement of the inflowing wind. The window flow path 570 allows the rotor blades 530 of the window rotor 500 to operate effectively by facilitating the flow of air in the window rotor 500.
The window passage 570 for realizing this is composed of first, second, third and fourth window passages 570a, 570b, 570c, and 570d for inducing a smooth air flow around the rotor blade 530.

The first window channel 570a is formed between the inner end of the rotating blade 300 and the outer peripheral edge of the rotor blade 530, and the second window channel 570b is formed between the inner periphery of the guide tube 560 and the rotor blade 530, and The third window channel 570c communicates with the upper ends of the first window channel 570a and the second window channel 570b on the upper side of the rotor blade 530, and the fourth window channel 570d is located on the lower side of the rotor blade 530 with the first window. The lower ends of the flow path 570a and the second window flow path 570b communicate with each other.
As described above, when the window flow path 570 is formed around the rotor blade 530, a part of the air flowing into the rotor blade 530 can flow out of the rotor blade 530 while rotating together with the rotor blade 530. At this time, the air that has flowed out of the rotor blade 530 is guided again into the rotor blade 530 by the window passage 570, thereby further increasing the rotational speed of the rotor blade 530 and improving the torque of the rotor blade 530. By improving the power generation efficiency. Further, the window passage 570 smoothly discharges the air that has flowed into the rotor blade 530 so that the air can be quickly and smoothly flowed into the rotor blade 530.

  At this time, it is desirable that the area ratio between the rotor blade 530 and the window passage 570 satisfies 3: 7. This is because, in order to effectively realize the rotational operation of the rotor blade 530, the optimum area ratio between the rotor blade 530 and the window passage 570 that can achieve the smoothest air flow in the window rotor 500 is obtained. However, in order to obtain the optimum area ratio, the present inventor has gone through many trials and errors and found that the resulting ratio configuration is most suitable. Therefore, if the composition of the above ratio is deviated, the air flow in the wind rotor 500 may be reduced.

Preferably, the plurality of solar panels are vertically or laterally separated from the upper layer or side wall of the ventilation tower 100. Arranged. However, since the installation structure of the solar panel is affected by the incident angle of the sun and the amount of sunlight, it can of course be changed depending on the region and the surrounding environment.
The electric energy generated by the solar cell module 710 is charged by the storage battery.
The battery can charge the electric energy generated through the solar cell module 710 during the time from sunrise to sunset when solar power generation is possible, and can use the charged electric energy as necessary. This battery is controlled by the solar control panel 720.

The solar control panel 720 is in charge of general control necessary for the operation of the solar cell module 710 and the electric storage device, and is used as electric power necessary for the operation of the ventilation tower 100 through the electric energy stored in the electric storage device as necessary. Or used as operating power for a separate plant cultivation facility 800.

However, if the rotor blade 530 is maintained in an operating state as in the present invention, it is positive for the wind state that changes in real time. It can be applied to wind power generation even at low speed wind.

In order to realize this, a wind speed sensor, an air nozzle 630, an air tank 640, and a control unit 620 are installed in the wind power generation tower.
Here, the wind speed sensor is installed in each layer of the ventilation tower 100 and measures the speed of the wind flowing into the wind rotor 500 in real time. The air nozzle 630 is disposed to face the rotor blade 530 of the window rotor 500 so as to inject air toward the window rotor 500 when an operation signal is applied by the controller 620. The air tank 640 stores high-pressure air and provides it to the air nozzle 630. The controller 620 applies an operation signal to the air nozzle 630 so that the rotation of the rotor blade 530 is maintained if the wind speed measured by the wind speed sensor is equal to or lower than a certain speed.

In the present embodiment, the ventilation tower 100 configured by a multi-layer tower having a quadrangular cross section has been described. However, the shape of the ventilation tower 100 can be variously changed. For example, as shown in FIGS. 10a and 10b, the ventilation tower 100 may be a multi-layered tower having a hexagonal cross section, or the ventilation tower 100 may have a corresponding cross section as shown in FIGS. 11a and 11b. However, as shown in FIGS. 12a and 12b, the ventilation tower 100 may be formed of a multi-layer tower having a circular cross section.
