1A and 1B are a side view and a cross-sectional view showing a tunnel type wind power generator 100A according to an embodiment of the present invention, and FIGS. 2A and 2B are side views showing a tunnel type wind power generator 100B according to an embodiment of the present invention. and cross-sectional views.

1a, 1b, 2a and 2b, the tunnel type wind power generator 100A, 100B according to an embodiment of the present invention has a tunnel unit 110, an electric motor 120, a generator 130 and a wind speed guide unit. (140).

In addition, the tunnel-type wind power generators 100A and 100B according to an embodiment of the present invention may further include a case unit 150 installed on the exterior of the tunnel unit 110 .

Moreover, the tunnel type wind power generators 100A and 100B according to an embodiment of the present invention may further include a battery 160 (see FIG. 3 ).

The tunnel unit 110 may have a hollow, long cylindrical shape having an approximately circular inlet 111 and an approximately circular outlet 112 formed on the opposite side of the inlet 111 . In some cases, the diameter of the outlet 112 may be smaller than that of the inlet 111 of the tunnel unit 110 . For example, the diameter may gradually decrease from the inlet 111 to the outlet 112 . Accordingly, the wind speed may further increase as going from the inlet 111 to the outlet 112 . The tunnel unit 110 may be made of stainless steel, aluminum, copper, nickel, an alloy thereof, plastic, or synthetic resin.

Here, the diameter gradually decreases from the entrance 111 to the exit 112 of the tunnel unit 110, but the size of the generators 130 arranged in a line may all be the same. Accordingly, the power generation capacity of all generators 130 may be similar. In addition, the diameter gradually decreases from the entrance 111 to the exit 112 of the tunnel 110, and at the same time, the size of the generators 130 arranged in a line also gradually increases as going from the entrance 111 to the exit 112. can be small Accordingly, as it goes from the entrance 111 to the exit 112 of the tunnel unit 110 , the power generation capacity of the generator 130 may also gradually decrease.

The electric motor 120 is installed at the entrance 111 of the tunnel unit 110 and may have a plurality of blades (or turbines). When the wind speed is less than the reference wind speed, the electric motor 120 receives power from the battery 160 (discharges the battery) and rotates the blade, so that the wind can be sent to the rear side, that is, the generator 130 . However, when the power of the battery 160 is lower than the reference power, the power of the battery 160 is not supplied to the electric motor 120 (stop discharging the battery). In addition, the electric motor 120 may be a combined generator motor. In this way, when the wind speed is less than the reference value, the generator combined motor operates as an electric motor and consumes power of the battery 160 (battery discharge), but when the wind speed is greater than the reference value, it operates as a generator to supply power to the battery 160 Can supply (battery charging).

The generator 130 is installed in a line from the rear of the electric motor 120 to the outlet 112 and may include a plurality of blades (or turbines), respectively. Although nine generators 130 are shown in the drawing, there may be fewer or more than this. In this way, the generator 130 converts wind energy into electrical energy, and stores it in the battery 160 . In addition, the generator 130 may be a combined generator motor. That is, both the electric motor 120 and the generator 130 described above may operate as a motor that blows the wind backward. Accordingly, the tunnel-type wind power generators 100A and 100B according to the present invention may be used as an auxiliary device or a main device for pushing forward a transportation means such as a car or a ship in some cases.

The wind speed guide unit 140 is installed to extend forward at the entrance 111 of the tunnel unit 110, and when the wind speed is smaller than the preset reference wind speed, the diameter of the front end becomes larger than the preset reference diameter (for example, (greater than the entrance diameter of the tunnel 110), when the wind speed is greater than the preset reference wind speed, the diameter of the front end may be smaller than the preset reference diameter (for example, the tunnel 110 is smaller than the entrance diameter) . Here, the wind speed guide unit 140 may be installed in front of the case unit 150 instead of the tunnel unit 110 .

In addition, since the wind speed guide unit 140 is composed of a plurality of overlapping plates, there may be no empty space between the overlapping plates regardless of the diameter of the front end. For example, in the wind speed guide unit 140, when the diameter of the front end is relatively large, the overlapping area between the overlapping plates becomes relatively small, and when the diameter of the front end is relatively small, the overlapping area between the overlapping plates becomes relatively large. can The wind speed guide unit 140 may be made of stainless steel, aluminum, copper, nickel, or an alloy thereof.

In addition, the wind speed guide unit 140 may further include a plurality of cylinders 141 installed between the wind speed guide unit 140 and the tunnel unit 110 (or the case unit 150). For example, when the rod of the cylinder 141 is extended, the shear diameter of the wind speed guide part 140 may be reduced, and when the rod of the cylinder 141 is reduced, the shear diameter of the wind speed guide part 140 may be increased.

In general, when air passes through the tunnel 110 having the same diameters as the inlet 111 and the outlet 112 , the air velocity v1 of the inlet 111 and the cross-sectional area of the inlet 111 as shown in the following equation The product of (A1) is equal to the product of the air velocity (V2) at the outlet (112) and the cross-sectional area (A2) at the outlet (112).

V1A1 = V2A2

As can be seen from the above equation, for example, if the cross-sectional area of the inlet 111 of the tunnel 110 is increased while the cross-sectional area of the outlet 112 of the tunnel 110 is fixed, the It can be seen that the air velocity must be increased.

Additionally, it can be seen through the following equation that the output of the generator 130 is further improved when the air speed is increased. That is, the output (P) of the generator 130 is proportional to the cube of the air velocity (V).

P = 1/2 (ρV ³ )

Here, P is the output of the generator 130, ρ is a constant, V is the air velocity.

In this way, in the embodiment of the present invention, by increasing the speed of the air according to the wind speed guide unit 140, it can be confirmed that the output of the generator 130 is increased by approximately 60% or more.

The case unit 150 may protect the tunnel type wind power generator 100A from the external environment by wrapping approximately the outer side of the tunnel type wind power generator 100A and 100B. However, as described above, the wind speed guide unit 140 is installed in front of the case unit 150, the front may be opened or blocked. In addition, the rear of the case unit 150 may be opened so that the wind by the electric motor 120 and/or the generator 130 can escape to the rear.

The battery 160 may be discharged by charging power generated from the generator 130 or by supplying power to the electric motor 120 . In some examples, battery 160 may include a lithium ion battery, a lithium polymer battery, or a solid-state battery. The battery 160 includes an overcharge prevention circuit for preventing an overcharge state by the power from the generator 130, and an overdischarge prevention circuit for preventing an overdischarge state by the power supplied to the electric motor 120 can

In this way, the embodiment of the present invention can provide the tunnel-type wind power generators 100A and 100B that are installed on the rooftop of a hybrid vehicle or electric vehicle and can generate and charge while the vehicle is running. In addition, the embodiment of the present invention can provide a tunnel-type wind power generator (100A, 100B) capable of generating electricity while consuming electricity by generating wind in a place where there is not much wind. In addition, the embodiment of the present invention can be miniaturized to provide a tunnel type wind power generator (100A, 100B) that can be used as a wind power generation facility by using an oyster of an abandoned railway by making it possible to charge small household appliances such as mobile phones in camping or remote areas. have.

The wind speed sensor 171 is installed in the tunnel unit 110 , the case unit 150 , or the vehicle, senses the wind speed supplied to the tunnel type wind power generators 100A and 100B, and converts it into an electrical signal to the control unit 173 . can be transmitted The speed sensor 172 may, for example, read information from a speedometer already installed in the vehicle and transmit it to the controller 173 . The speed sensor 172 may be omitted when the tunnel type wind power generator 100A according to the present invention is fixedly installed without being transported like a vehicle or a ship. In addition, when the tunnel-type wind power generators 100A and 100B according to the present invention are installed in a transportation means such as a vehicle or a ship, the wind speed sensor 171 may be omitted.

The wind speed guide unit 140 may be controlled by a control signal from the control unit 173 .

For example, when it is determined that the wind speed by the wind speed sensor 171 is smaller than the reference wind speed, the control unit 173 controls the cylinder 141 so that the diameter of the front end becomes larger than the reference diameter (eg, the rod of the cylinder 141 ). can be reduced). As another example, when it is determined that the wind speed by the wind speed sensor 171 is greater than the reference wind speed, the controller 173 controls the cylinder 141 so that the diameter of the front end is smaller than the reference diameter (eg, the rod of the cylinder 141 ). can be extended).

As another example, when it is determined that the speed by the speed sensor 172 is smaller than the reference speed, the control unit 173 controls the cylinder 141 so that the diameter of the front end becomes larger than the reference diameter (eg, of the cylinder 141 ). load reduction). As another example, when it is determined that the speed by the speed sensor 172 is greater than the reference speed, the control unit 173 controls the cylinder 141 so that the diameter of the front end is smaller than the reference diameter (eg, the rod of the cylinder 141 ). can be extended).

In addition, the control unit 173 synthesizes the information obtained from the wind speed sensor 171 and the speed sensor 172 to control the shear diameter or opening degree of the wind speed guide unit 140, so that the shear of the wind speed guide unit 140 more accurately. Diameter or degree of opening can be controlled.

The generator 130 serves to charge the battery 160 by generating power as described above. Of course, at this time, AC power may be converted into DC power by the AC-DC converter 174 , and the voltage may be adjusted to be supplied to the battery 160 . Meanwhile, the generator 130 may also operate as the generator 130 according to a control signal of the controller 173 or may operate as a motor as described above. When the generator 130 operates as a motor, power may be supplied from the battery 160 .

The electric motor 120 may also receive power from the battery 160 and transmit wind to the generator 130 at the rear stage as described above.

* For example, when the wind speed obtained from the wind speed sensor 171 is less than the reference wind speed, or the speed obtained from the speed sensor 172 is smaller than the reference speed, the control unit 173 may control the power of the battery 160 to the electric motor 120. to be supplied to

As another example, when the wind speed obtained from the wind speed sensor 171 is greater than the reference wind speed or the speed obtained from the speed sensor 172 is greater than the reference speed, the control unit 173 may supply the power of the battery 160 to the electric motor 120 . supply can be blocked.

However, when the current capacity of the battery 160 is smaller than the predetermined reference capacity, the control unit 173 may control the power of the battery 160 even if the wind speed and/or speed is smaller than the reference wind speed and/or the reference speed. 120) is blocked.

On the other hand, when the wind speed is greater than the reference wind speed and/or when the speed is greater than the reference speed, the control unit 173 may control the electric motor 120 , that is, the generator combined motor to operate as the generator 130 . Therefore, when the wind speed or speed is higher than a preset reference value, the generator-combined motor also operates as the generator 130 , thereby further improving the charging efficiency of the battery 160 .

4A and 4B are a plan view and a side view illustrating a state in which tunnel-type wind power generators 100A and 100B according to an embodiment of the present invention are mounted on a vehicle.

4A and 4B , the tunnel-type wind power generators 100A and 100B according to an embodiment of the present invention may be installed on a rooftop of a hybrid vehicle or an electric vehicle. For example, the front and rear may be opened, and a plurality of tunnel-type wind power generators 100A and 100B may be installed inside the case unit 150 having an upper surface, a lower surface and both sides. Here, the inlet 111 of the tunnel wind power generator 100A, 100B may face the front of the vehicle, and the outlet 112 of the tunnel wind power generator 100A, 100B may face the rear of the vehicle. Accordingly, as the tunnel-type wind power generators 100A and 100B are naturally generated when the vehicle is driving, the battery 160 mounted in the vehicle may be charged.

Meanwhile, as described above, in some cases, both the electric motor 120 and the generator 130 operate as motors, so that the tunnel type wind power generators 100A and 100B may provide thrust to the vehicle. Accordingly, the traveling speed of the vehicle may be improved by the tunnel type wind power generators 100A and 100B.

In addition, an embodiment of the present invention is a solar array arranged in series or in parallel with a light collecting unit for condensing sunlight on the upper surface of the case unit 150 and solar cells that generate electricity by absorbing sunlight collected by the light collecting unit A battery module may be further provided. Of course, the power generated by the solar cell module may be charged in the battery 160 . Accordingly, in the embodiment of the present invention, the charging efficiency of the battery 160 may be further improved.

5A to 5C are photographs showing a tunnel type wind power generator 100A according to an embodiment of the present invention.

5A to 5C , in the tunnel type wind power generator 100A according to an embodiment of the present invention, an electric motor 120 and a plurality of generators 130 may be installed inside the cylindrical tunnel part 110 . have. Accordingly, the battery 160 mounted on the vehicle may be charged from the tunnel type wind power generator 100A, or a small home appliance may also be charged. On the other hand, since it may be difficult to form the tunnel part 110 long at a time, it may be divided into a plurality of short cylindrical unit tunnels, and the long cylindrical tunnel part 110 is provided by welding and coupling the plurality of cylindrical unit tunnels to each other. can be

Here, the electric motor 120 and the generator 130 may be coupled to the boundary of the plurality of cylindrical unit tunnels. As an example, the supporting plates 121 and 131 supporting the electric motor 120 and the generator 130 are interposed between the cylindrical unit tunnel on one side and the cylindrical unit tunnel on the other side and fixed, and also the cylindrical unit tunnel on one side and the cylindrical unit tunnel on the other side. The unit tunnels can be welded and fixed to each other.

6 is a cross-sectional view showing a tunnel type wind power generator according to another embodiment of the present invention.

As shown in Figure 6, the embodiment of the present invention may further include an auxiliary wind speed guide unit 175 installed at the front end of the generator. For example, the auxiliary wind speed guide unit 175 may be in the form of a cone whose diameter gradually increases from the entrance of the tunnel unit 110 toward the exit of the tunnel unit 110 . However, the tip of the auxiliary wind speed guide part 175 coincides with the approximate center line of the tunnel part 110 , and the end of the auxiliary wind speed guide part 175 may be spaced apart from the inner wall of the tunnel part 110 by a predetermined distance.

Practically, the wind supplied to the center of the blade 132 of the generator 130 does not help the rotation of the blade 132 . Therefore, the embodiment of the present invention provides a cone-shaped auxiliary wind speed guide part 175 so that the wind can be concentrated in a region that substantially helps the rotation of the blade 132 . Furthermore, since the cross-sectional area between the end of the auxiliary wind speed guide part 175 and the inner wall of the tunnel part 110 is small compared to the cross-sectional area of the total inner diameter of the tunnel part 110, the wind speed is further increased and the blade of the generator 130 The number of rotations of (132) is further increased.

This cone-shaped auxiliary wind speed guide part 175 is installed spaced apart only in front of the blade 132 of the generator 130 closest to the exit side of the tunnel part 110, thereby effectively increasing the speed of the reduced wind speed again. can do it Of course, the auxiliary wind speed guide unit 175 may be installed in front of the blades 132 of all generators 130 in the tunnel unit 110 .
