Description

Bladeless artificial intelligence wind turbine structure

The present invention relates to a wind turbine structure, and in detail, is configured to remove the large blades exposed to the outside in the conventional wind power generator, adjust the amount of incoming wind, and rotate the turbine from the inside, so that even in a strong wind situation, there is no separate brake control. It relates to an artificial intelligence wind turbine structure with no rotor blades that rotates a turbine through the applied wind pressure and enables stable power generation and safe operation.

Recently, as the environmental pollution problem caused by fossil fuels has become serious, a lot of research and development on eco-friendly renewable energy such as wind power or solar power is being conducted.

Among them, wind power generation is achieved through a structure that installs a large blade that rotates through the wind on a vertically installed tower, a generator that produces power through it, and ancillary equipment on the top of the tower.

These wind power generators basically require a relatively wide installation space as large blades are exposed to the outside. The disadvantage is that the range is widened.

In particular, as noise generated during high-speed rotation of large blades and generator operation noise became a cause of complaints from surrounding areas, it had to be installed outside the city center, resulting in power loss during power transmission, and the risk of damage due to high-speed rotation of blades exposed to the outside. It was great.

Accordingly, accidents often occurred in the process of automatically operating the brake for controlling the rotation speed of the blade at the limit wind speed (25 m/s) in the blade design due to typhoons or gusts, and it was difficult to achieve stable power generation due to the operation stop.

In addition, in low-speed wind, it is difficult to control wind power, such as a separate motor must be provided for the initial rotation of large blades, and compared to large blades, safety problems due to the location of the configuration for power generation in a narrow space, instability of power generation, application of offshore wind power Excessive costs were incurred due to the mobilization of a large number of manpower and large equipment in the repair and maintenance process, such as requiring large-scale production costs and O&M.

The present invention is made in the form of a tower that can receive wind at a set height from the ground or water surface similar to the conventional wind power generator, and has a body part 110 that receives wind pressure and introduces wind, and a column shape with a set height and has an upper side. It consists of a tower part 130 to which the body part 110 is installed.

The body portion 110 is formed in a cylindrical shape having a set width and length through the center, and a portion of the wind blowing from the front to the rear is configured to penetrate the center. In addition, a plurality of wind inlet holes 111 are formed along the front edge of the body 110 , and a portion of the wind blowing from the front is introduced into the body 110 through the inlet holes.

The size and number of the inlet holes 111 may be variously adjusted according to the size and number of the body portion 110 , but the present invention is not limited thereto. In addition, the present invention may be applied to and installed on land, but may also be installed on the sea. Preferably, the diameter of the body part 110 is manufactured to a level of 50 m to suit the offshore power generation structure, and the tower part 130 is a structure supporting it. It can be manufactured with a diameter of 8 m.

7 is a partial view showing the shape of the body according to another embodiment.

In the present invention, as a preferred embodiment, the body part 110 is exemplified in a circular shape as shown in FIG. The body portion 110 may be configured in various polygonal shapes, including an ellipse as in FIG. 7(b), and a rectangle or square as in FIG. 7(c).

Inside the body part 110, a transfer pipe 121 for transferring the wind introduced into each inlet hole 111, and the transfer pipe 121 are assembled, and the air transferred from the end is blown out. An air passage unit 120 made of a blower pipe 123 is installed.

That is, a transfer pipe 121 is installed in each inlet hole 111 so that the introduced wind moves to the rear side, and the ejection tube 123 collects the wind transferred from each transfer tube 121 to form a turbine to be described later. will be sprayed At this time, the blower pipe 123 is connected to all transfer pipes and may blow wind to the turbine through a single blowout pipe 123, but each blowout pipe ( 123) is provided and the opposite end is arranged side by side on the side of the turbine so that the wind can be blown out.

The tower part 130 is a pillar-shaped structure in which the body part 110 is installed at the upper end, and can be installed on the ground as well as on the sea. In addition, in the conventional wind power generator, substantially all the components necessary for power generation are installed in the structure on the upper side of the tower, whereas in the present invention, the body 110 serves to accelerate and induce the wind, and the elements required for wind power generation are provided. Built in the tower unit 130, it is very advantageous in terms of maintenance and management.

Specifically, a turbine 131 rotating through the air blown out through the jet pipe 123 is installed on the inner upper portion of the tower unit 130 , and a speed reducer 132 that adjusts the rotational force of the turbine 131 to a set speed. ) and a generator 133 for generating power through the rotational force reduced through the reduction gear 132 is installed.

At this time, it is self-evident that the exhaust port 135 must be formed in the tower part 130 so that the wind that is ejected through the ejection pipe 123 and rotates the turbine 131 can be discharged to the outside, and if necessary, it is connected to the generator It is also possible to properly convert the voltage produced by incorporating a transformer 134 that is.

Through such a structure, it is possible to effectively protect the facility from strong wind, which is the biggest problem, because any structure that rotates through the wind, such as a propeller, is not exposed to the outside.

Of course, even in the structure of the present invention, when a strong wind occurs, the amount of wind introduced through the wind path unit 120 increases, which may cause a problem due to high-speed rotation of the turbine. It is configured to control the strength and amount of wind.

3 is a partially enlarged view showing an inlet opening/closing structure according to an embodiment of the present invention, and FIG. 4 is a view showing a durable structure of an air passage according to an embodiment of the present invention.

First, the inlet hole 111 and the transfer pipe 121 are configured to have a cross section of an elongated oval on the side, and a plurality of partition walls 122 crossing the left and right sides are formed inside the transfer tube 121 to form a zigzag shape. The passage area is adjusted at the same time as the passage is formed, and the wind speed (wind speed) can be increased by forming a gorge.

In addition, the opening/closing plate 112 configured to selectively open and close the inlet hole 111 and a driving unit for driving the opening/closing plate 112 may be configured in the body unit 110 . That is, the opening and closing plate 112 can be opened and closed through sliding movement of the opening and closing plate 112 built-in along the front surface of the body 110 or provided on the outside of the inlet hole. ) to open and close the entire inlet hole or adjust the degree of opening and closing to adjust the inflow air volume, but the number of inlet holes opened and closed by installing an opening/closing plate 112 and a driving unit 113 for each inlet hole 111 It can also be configured in a way that adjusts the

To this end, basically, the opening/closing plate 112 is manufactured to have a relatively larger area than the inlet hole 111, and is built into the body 110 to block the front surface of the inlet hole 111, and the inlet hole 111. It is configured to move in the vertical direction or the left and right direction of the inlet hole 111 to control the opening and closing degree of the opening. 3(a) and 3(b) show the movement of the opening/closing plate 112 in the vertical direction, and FIGS. 3(c) and 3(d) in the left and right directions, respectively, and the opening/closing plate 112 is It is necessary to provide sufficient space and a gap between the inlet holes to open and close the inlet hole 111 while moving.

The driving unit 113 is configured to open and close the inlet hole 111 by moving the opening/closing plate 112 in an electric manner. Although the opening and closing plate 112 coupled thereto moves in the vertical or left and right directions along the worm to open and close the inlet hole 111, various well-known methods may be applied.

In other words, if the wind speed exceeds a certain speed (for example, 25 m/s) due to typhoons or gusts of wind, the brake is automatically applied to prevent the propeller from rotating in order to prevent damage. In the process, damage and accidents frequently occurred, and there was no power generation, which made it difficult to secure a stable power supply.

However, in the present invention, for example, when the wind is strong in a state in which 100 provided inlet holes are installed, only 20 to 50% of the total inlet holes are opened to control the amount of the total incoming wind, so the high speed of the turbine 131 Continuous power generation can be made without fear of damage due to rotation, and in particular, when a very large typhoon occurs, by closing all the opening and closing plates 112, a series of built-in components can be completely protected and safe operation can be achieved.

8 is a view showing a body portion rotating structure according to another embodiment of the present invention.

In Korea, which is under the influence of the westerly wind, it is affected by the westerly wind throughout the year, but the direction of the wind may change due to the topography and seasonal factors. At this time, since the front of the body part 110 in which the inlet hole 111 is formed should always face the windward side for stable power production, the connection part of the body part 110 and the tower part 130 has the body part 110 according to the wind direction. ) so that it can rotate, that is, it is necessary to configure the rotating part 136 having the bearing 137 so that the front surface of the body part 110 always faces the windward side.

That is, it is rotatable through a bearing at the upper end of the tower unit 130 and is installed so that the body unit 110 does not separate through a stepped structure, etc., and when the wind direction changes, the wind passes through the center of the body unit 110 and By reducing the resistance of the passing wind, the state in which the front surface of the body part 110 naturally faces the windward side can be maintained. In general, when the direction of the wind is changed, rather than a sudden headwind occurs, it is changed over a relatively long period of time, so there is a low risk that the rear surface of the body portion 110 in which the inlet hole 111 is not formed faces the windward side, but as necessary In order to prevent such a problem from occurring, the thickness of the body 110 may be configured to gradually thicken from the front to the rear, or may be configured such as wings protruding from the rear side of the body 110 .

In addition to this, it is also possible to rotate the body portion 110 in an electric manner to an optimal position where the wind flows in the most through the inlet 111 . That is, as shown in the accompanying FIG. 8, the rotation motor 138 is provided on the body part 110 side, but a gear part 139 which is meshed with the end of the shaft of the rotation motor 138 and the upper end of the tower part 130 is formed. Accordingly, the rotation of the body part 110 can be made according to the driving of the rotation motor 138 .

At this time, as mentioned above, the body part 110 has a cylindrical shape penetrating in the front and rear directions, so using the inner space without a blade, a light emitting part 114 made of a laser or LED is installed to provide a specific logo, pattern, By allowing the output of video contents including text, various attractions that match the surrounding landscape can be provided, and through this, tourist attractions can be created.

In addition, in case the wind volume is somewhat insufficient as power is generated inside the body part 110, auxiliary means capable of minimizing resistance such as magnetic bearings are provided on the shafts of the turbine, the reducer, and the generator so that power generation can be achieved even with a small amount of wind. It is preferable to configure it so that it is done.

Based on this structure, a sensor that can measure the air volume is installed on the inlet side of each inlet hole 111 and the outlet side of the outlet pipe 123, and the most suitable amount for development is learned through the AI algorithm after connection collection. Safe and continuous development can be achieved by allowing the inflow of wind and ensuring a continuous supply.

That is, according to the degree of opening and closing of the inlet hole 111, the incoming wind speed is sensed, and the speed and amount of wind finally supplied to the turbine for power generation is appropriately adjusted, but optimized power generation is achieved through AI deep learning.

The control unit 140 provided for this purpose controls the aforementioned driving unit 113 and the light emitting unit 114 and controls the overall operation of power generation, as well as the first wind pressure sensor 141 and the second wind pressure sensor 142 . And, it is provided with the detailed configuration of the storage unit 143, the learning unit 144, and the application unit 145.

The first wind pressure sensor 141 and the second wind pressure sensor 142 each have the inlet hole 111 to measure the wind power flowing into the inlet hole 111 and the wind power blowing out through the outlet pipe 123 , respectively. ) is installed on the inlet side and the outlet side of the jet pipe 123 .

The storage unit 143 is a memory, and stores the control signal of the driving unit 113 and the measured values of the first wind pressure sensor 141 and the second wind pressure sensor 142 over time.

The learning unit 144 is configured with a deep learning algorithm, analyzes the data accumulated in the storage unit 143, and responds to the measured value of the first wind pressure sensor 141 of the second wind pressure sensor 142. The control pattern of the driving unit 113 is derived so that the measured value has a set range.

That is, it learns the amount of air supplied to the turbine 131 compared to the amount of air inflow according to the control of the driving unit 113 and learns under what wind inflow conditions the optimum airflow amount to the turbine is derived. (111) is to control the amount of wind flowing in through the continuous optimal power generation.

The application unit 145 applies the control pattern derived from the learning unit 144 to control the driving unit 113. As the amount of learned information increases, the air volume control is gradually optimized.
