Description

{LOUVER GUIDED WIND TURBINE}

The present invention relates to a wind power generator for obtaining energy by colliding a kinetic energy of a wind flow with a rotating body, and more particularly, to a wind power generator for guiding a wind flow to a rotating body, Generator.

Generally, a generator is a device that converts mechanical energy into electrical energy. The generator includes a body, a rotor mounted rotatably on the body, a rotating shaft rotating by an external force, and a plurality of coils wound around the rotating shaft, wherein the rotor is provided on the outside of the rotor, And a stator made of a magnet fixedly mounted inside.

When the rotation shaft is rotated by an external force, a coil coupled to the rotation shaft rotates, and a current through an electromotive force flows into the coil due to a magnetic field generated in the magnet. These generators are classified into hydraulic power, thermal power, wind power and nuclear power depending on the power source for rotating the rotary shaft.

Particularly, a generator based on wind power mainly rotates the rotating shaft by using a wind flow, and a device for rotating such rotating shaft is called a wind power generator. That is, the wind turbine generator is a device that generates electric power by rotating the rotary shaft of the generator using the wind flow.

These wind turbines can be classified into two types, horizontal axis wind turbine and vertical axis wind turbine, depending on the direction of the rotating shaft. The horizontal axis wind power generator is a wind power generator in which the rotation axis of the rotating body is horizontal to the wind direction and the vertical axis wind power generator is a wind power generator in which the rotation axis of the rotating body is perpendicular to the wind direction.

If the wind speed exceeds 5m per second, it is considered to have high economic value. According to the map of wind generated by the National Meteorological Research Institute, the most abundant wind resources in Korea are Jeju Island, Baekdudaegan Ridge and West Coast. However, more research is needed to utilize wind resources effectively in Korea, which has fewer plains and mostly mountainous terrain.

In the case of a horizontal type wind turbine, it is necessary to install a yawing or pitching device according to the direction and intensity of the wind, and it is mostly used in an area rich in wind resources, when the wind in a certain direction blows steadily. Vertical wind turbines, on the other hand, have a low failure rate and high power generation ratios. The minimum wind speed required to turn the wing of a horizontal wind power generator is 4 m per second, while the vertical wind power generator produces enough power to turn on three 20 watt halogen bulbs at a wind speed of 3.9 m / sec.

This type of vertical wind turbine is considered to be suitable for the situation in Korea because it is less affected by wind direction and wind speed. With the spread of small wind turbines such as vertical wind turbines, wind power is expanding to the city center. As the buildings in the city become increasingly high-rise, the building style is being reborn as renewable energy.

In the case of the vertical wind turbine as described above, there is also a saberoid type, a darius type, a gyro-mill type, a cross flow type, and the like depending on the shape of the rotating body that receives the wind flow and rotates the rotary shaft.

The Sabonius type is named after the Dutch Savonius, consisting of two semi-cylindrical wings, with the left and right wings alternating with each other leaving a slightly overlapping portion in the circumferential direction. As a result, the wind that exits between the right and left wings flows to the back side of the opposite wing, thereby enhancing the rotation efficiency by pushing in the rotational direction and suppressing the resistance of the upwind.

The Darius type is a windmill invented by the Frenchman Darius. Two to three wings are common, and unlike the Sabonius type that uses drag, it is a lifting type and has a very large number of revolutions. Since there is no influence on the wind direction, no rudder is necessary, but since the torque obtained from the wind in the stop state is very small, it is difficult to start rotation by the magnetic force. Therefore, countermeasures such as improving maneuver in combination with a starting motor or a sandwich type should be taken .

The gyro mill type is an improved version of the Darrie type and is a vertical blade type windmill with the same cross section as the airfoil. Since the starting torque is very low like the Darius type, it is necessary to improve the maneuverability by combining with the saberoid type. Once started, the peripheral speed ratio is high and the rotation torque is high.

The crossflow type is designed such that a long tapered wing is attached to the edge of the disk at an appropriate angle to attach several pieces at regular intervals so that the inner wind passes through the gap of the wing through the inner cavity and is discharged to the outside through the gap of the opposite wing It is a windmill rotating in a certain direction. Of course, depending on the characteristics of the vertical wind turbine, the wind is omnidirectional, and it winds in all directions and rotates.

There are a large number of patents relating to the above-mentioned vertical wind turbine. The first is to secure the maneuverability of the rotor even in a small wind, and to increase the rotational force during the start of the second rotating body, And the shape of the whole is changed.

It is a matter of course that the present invention also aims at securing the maneuverability of the rotating body even in a small wind as a vertical wind power generator and increasing the turning force when the rotating body is started. In addition, the flow of wind guided to the rotating body can be automatically changed according to the wind speed, so that the rotating body can be more efficiently rotated from the initial start of the rotating body to the rotation after the starting.

It is an object of the present invention, which is conceived from the above-described viewpoints, to automatically change the wind flow guided to the rotating body according to the wind speed in accordance with the actual situation of the country, Which is capable of rotating the rotating body.

Other objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments with reference to the accompanying drawings.

In order to achieve the above object, a louver induction type wind turbine according to the present invention comprises a frame divided into a lower power generator and an upper rotating part, and a frame rotatably installed in the frame from the upper end of the rotating part to the lower end of the power generator A pair of rotatable fixing members each of which is rotatably coupled to the shaft so as to face each other up and down inside a rotating portion of the frame, a plurality of fixed bars extending radially around the shaft, Wherein the blades are arranged at equal intervals in an arc in the circumferential direction with respect to the shaft, and each of the blades is vertically installed between the fixing bars of the pair of rotator fixing members, A rotating body rotating together with a pair of rotating body fixing members to generate rotational force on the shaft, Each of which is disposed in an arc shape along the outer circumferential direction of the rotating body and is rotatably installed on the outer circumference of the rotating portion of the frame and is formed into a flat airfoil shape and is rotated by receiving a lift toward the incoming wind A plurality of louvers; a power generation module installed in a power generation portion of the frame so as to be disposed at a lower end of the shaft and generating power by receiving a rotation moment of the shaft; And a variable inertia module that changes the inertial moment so that the moment of inertia increases as the rotational speed of the shaft increases and decreases as the rotational speed of the shaft decreases.

The variable inertia module may include a body formed of a hollow top of the hollow body and a plurality of flexible inertia modules arranged to move freely within the body and to be centered on the bottom surface of the body when the rotation of the shaft is stopped, And a plurality of mass balls moving in an outer radial direction on the bottom surface of the body as the shaft rotates and the speed increases.

The body of the variable inertia module may include a plurality of partitions partitioning the inside of the variable inertia module at regular intervals radially from the center of rotation, and each of the mass balls of the variable inertia module may be divided into the same number Is filled.

Further, each of the louvers is characterized in that the rotary shaft is located on a flat aerodynamic center.

Each of the blades of the rotating body is formed in the shape of a flat foil airfoil and the leading edge is fixed to the end of the fixed bar of the rotating body fixing member and the trailing edge is fixedly installed on the adjacent fixed bar of the rotating body fixing member And a swirling vortex space in which a swirling wind is introduced between the rotating shaft and the rotating body is formed.

The vortex guiding plate may further include a vortex guiding plate fixed to the center of the upper portion of the rotating portion of the frame and guiding the vortex generated from the vortex space portion to a position above the rotating portion of the frame.

The louver induction type wind turbine according to the present invention can automatically change the wind flow guided to the rotating body according to the wind speed in accordance with the actual situation of Korea through a plurality of louvers rotatably provided in the airfoil shape, It is possible to rotate the rotating body more efficiently at the time of starting from the initial start to after starting.

Particularly, when the rotation speed of the shaft is increased through the variable inertia module that rotates together with the shaft, the moment of inertia becomes large, and when the rotation speed of the shaft becomes small, the moment of inertia becomes small so that the rotation speed of the shaft can be constantly limited , The rotation speed of the shaft can be limited even at an excessive wind speed, so that the power generation can be performed and efficient power generation can be achieved.

In addition, the swirling space formed between the shaft and the rotating body generates a swirling space, thereby generating a suction force in the wind that flows into the rotating body, thereby enabling more efficient rotation. So that the flow of wind can be smoothly guided and the power generation efficiency can be improved.

Hereinafter, preferred embodiments of a louver induction type wind turbine according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 11, the louver induction type wind turbine according to the present invention includes a frame 100, a shaft 200, a rotating body fixing member 300, a rotating body 400, a louver 500, The vortical space portion 800 may be formed between the shaft 200 and the rotating body 400 and may further include a vortex guide plate 900. [

The frame 100 is a skeleton to which various components to be described later are attached and coupled as shown in Figs. 1 and 2, and is vertically erected and partitioned into a lower power generation unit 110 and an upper rotation unit 120 . The power generation unit 110 under the frame 100 is a space in which a power generation module 600 to be described later is installed and may be provided with other acceleration and deceleration devices, constant voltage devices, power conversion devices, power storage modules, The variable inertia module 700 described later may be installed. The rotating part 120 on the upper side of the frame 100 is a frame structure with four open sides and a shaft 200 and a rotating body fixing member 300 to be described later are installed therein and a louver 500 is installed along the outer circumference.

The shaft 200 is rotatably installed in the frame 100 from the upper end of the rotation part 120 to the lower end of the power generation part 110 as shown in FIGS. A bearing that rotatably supports the shaft 200 may be provided inside the frame 100 so that the shaft 200 can be rotated. The shaft 200 rotates in response to the rotational force of the rotating body 400, which will be described later, and provides a rotation moment to the power generation module 600 to be described later so that the power can be generated. The louver induction type wind turbine according to the present invention corresponds to a vertical wind turbine because the shaft 200 rotates up and down vertically.

1 to 3, each of the rotating body fixing members 300 includes a plurality of fixing bars 310 radially extended around the shaft 200, Are coupled to the shaft (200) so as to face each other and rotate together. The rotating body fixing member 300 is fixedly coupled to the shaft 200 such that the pair of the fixing members 300 are symmetrically opposed to each other and are located inside the rotation portion 120 of the frame 100. The rotating body fixing member 300 is a member for fixing the rotating body 400 as will be described later. Each of the plurality of fixing bars 310 is radially extended to fix the rotating body 400 to be described later.

1 to 3, a plurality of blades 410 are arranged at an equal interval in an arc in the circumferential direction with respect to the shaft 200, The blades 410 are vertically installed between the fixing bars 310 of the pair of rotator fixing members 300 and rotate together with the pair of rotator fixing members 300 from the incoming wind, Thereby generating a rotational force in the main body 200. The shape of the blade 410 may be a saberoid type or a darari type or other shape as long as the rotating body 400 is provided on the rotating body fixing member 300 and can rotate together.

In particular, in the present invention, the rotating body 400 has a shape similar to that of a cross flow type. Particularly, each of the blades 410 of the rotating body 400 is formed into a flat airfoil shape, And a trailing edge is fixedly installed on an adjacent fixed bar 310 of the rotating body fixing member 300. [ The airfoil shape is composed of a leading edge that winds and a trailing edge that flows after the wind flows, as shown in FIG. 3, the leading edge of each of the blades 410 of the rotating body 400 is fixed to the end of the fixing bar 310 of the rotating body fixing member 300, (300). The shape of the blade 410 of the rotating body 400 may be formed in the form of an airfoil as will be described later in connection with the louver 500. However, And receives the drag force to rotate the blade 410 more easily when the wind is introduced into the lower camber surface of the blade 410 on the flat surface.

At this time, as shown in FIGS. 6 and 8, an eddy space portion 800 is formed in which a swirling wind is introduced between the rotating shaft 200 and the rotating body 400. The swirling space portion 800 is a region where a swirling wind is generated between the shaft 200 and the rotating body 400. The swirling swirling portion sweeps over the rotating portion 120 of the frame 100 through the swirling space portion 800, And is discharged upward. The vortex generated in the vortex space portion 800 functions to suck wind into the rotating body 400 and further facilitates the rotation of the rotating body 400. The vortex guide plate 900 may further include a vortex guide plate 900 as shown in FIG. 8 so that the vortex generated in the vortex space portion 800 can be discharged more efficiently when the vortex generated in the vortex space portion 800 is discharged above the rotation portion 120 of the frame 100 . The vortex guide plate 900 has a circular plate shape whose center is downwardly concave and is fixed to the center of the upper part of the rotation part 120 of the frame 100 to form a vortex generated from the vortex space part 800, Thereby guiding the rotation part 120 upward. It is possible to prevent the turbulence from being generated when the vortex is spread through the vortex guide plate 900 and the force is applied to the rotation of the rotating body 400 and the vibration is discharged above the rotation part 120 of the frame 100.

1 to 3, each of the louvers 500 is disposed in an arc shape along the outer circumferential direction of the rotating body 400, and the outer circumferential surface of the rotating portion 120 of the frame 100 And is formed in the form of a flat foil airfoil and receives a lift toward the incoming wind and rotates. Since the louver 500 is formed in the shape of an airfoil and rotates, the leading edge of the louver 500 is directed in the direction of wind blowing in any direction. Accordingly, each louver 500 rotates according to the direction of the blowing wind to induce the wind to the inner rotating body 400 through the trailing edge. 7, the louver 500 changes the size of the lift according to the change of the wind speed and changes the radius of rotation, and the direction of the wind guided through the louver 500 varies depending on the blade of each of the rotors 400 So that the rotation efficiency of the rotor 410 is further increased.

The louver 500 is rotatably installed to the left and right around the outer periphery of the rotation part 120 of the frame 100. The rotation axis of each louver 500 is an aerodynamic center as shown in FIG. . The aerodynamic center is a fixed point where the moment value is constant with respect to the change of the angle of attack with respect to the wind and is a fixed position that does not change with respect to the change of the angle of attack even if the turning radius of the louver 500 changes according to the change of the wind speed. The aerodynamic center of the symmetrical airfoil is at one quarter of the protest length from the leading edge (25% point of protest).

On the other hand, the louver 500 has another feature by being installed rotatably in the form of an airfoil. That is, regardless of the direction of the wind, the louver 500 located in the direction in which the wind is blowing rotates to guide the wind toward the rotating body 400, and is located on the opposite side of the louver 500 in the wind direction In the case of the louver 500, as shown in FIG. 6, there is an effect that the wind passing through the rotating body 400 can be easily guided to the outside without direct wind being blown. If the louver 500 is in a fixed state, it is affected by the directionality of the wind. In particular, if the wind passing through the rotating body 400 through the louver 500 located on the opposite side of the wind direction is discharged to the outside This is because turbulence is formed and the rotating efficiency of the rotating body 400 may be lowered.

2, the power generation module 600 is installed inside the power generation part 110 of the frame 100 so as to be disposed at the lower end of the shaft 200, and receives the rotation moment of the shaft 200, do. The power generation module 600 includes a rotor (not shown) formed of a coil having a plurality of coils wound around the shaft 200, and a magnet (not shown) provided on the outer side of the rotor, When the shaft 200 is rotated by wind, a coil coupled to the shaft 200 rotates, and a current through an electromotive force flows into the coil due to a magnetic field generated in the magnet do. Of course, the power generated by the power generation module 600 may be used by being stored through a capacitor (not shown) or the like and the power generated by the power generation module 600 may be used directly in the electric device.

As shown in FIGS. 2, 9, and 10, the variable inertia module 700 is configured such that when the rotation speed of the shaft 200 is increased, the moment of inertia is increased, and when the rotation speed of the shaft 200 is decreased, And is fixedly coupled to the shaft 200 to rotate together with the shaft 200. In inertia, inertia is the nature of an object that maintains its current state of motion, in which a stationary or moving object resists any force that moves due to inertia or changes its magnitude or direction . In other words, inertia is a passive property and does not affect an object other than to resist the active forces such as force or torque (torque).

The magnitude of this inertia can be divided into the inertia mass and the moment of inertia (rotational mass). Newton's second law, force, is expressed as the product of mass and acceleration (F = ma). In translation, the inertia of the object becomes mass (m), which is expressed as inertial mass. When applied to rotational motion, the rotational force is expressed as the product of the rotational mass (moment of inertia, I) and the angular velocity (T = Iα). In the rotational motion, the inertia of the object becomes the rotational mass and is expressed as the moment of inertia. Therefore, the moment of inertia is a quantitative measurement of the rotational inertia of an object, and refers to the magnitude of the resistance seen when an attempt is made to change the rotational speed around an axis by applying a rotational force to an object rotating about an axis. This moment of inertia (I) is expressed as a value for a particular axis of rotation, divided into small parts, the mass of each part multiplied by the square of the distance between the axis of rotation and each part, and then summing them together (I = Σmr ² ).

That is, it is difficult to change the inertia moment of an object in the rotational motion from the static state to the rotational motion. On the other hand, the small moment of inertia means that it is easier to change from the static state to the rotary motion. In order to apply this principle to the louver induction type wind turbine according to the present invention, the shaft 200 may be a specific rotation shaft and may be rotated together with the shaft 200, 400 and the variable inertia module 700, respectively. The variable inertia module 700 is rotated by the centrifugal force of the shaft 200 in accordance with the change of the rotation speed of the shaft 200 while the rotary fixed member 300 and the rotary body 400 are fixed to the shaft 200, So that the moment of inertia can be changed according to the size. That is, the variable inertia module 700 changes its moment of inertia to increase as the rotational speed of the shaft 200 increases, and decreases as the rotational speed of the shaft 200 decreases. The moment of inertia of the variable inertia module 700 is changed when the shaft 200 is in the stopped state and when the rotational speed at the time of initial startup is small, the moment of inertia is reduced, and the shaft 200 is changed from the stationary state to the rotational state The second shaft 200 can increase the moment of inertia when the second shaft 200 rotates at a high speed and can maintain the rotation motion continuously, and the rapid rotation speed of the shaft 200 can be limited. For example, when an arm or leg is pushed inside the body during rotational motion of a figure skater, the inertia moment decreases and the rotational speed increases. Conversely, when the arms or legs are spread outward, the inertia moment increases and the rotational speed is slowed down.

A specific configuration for changing the moment of inertia of the variable inertia module 700 according to the rotational speed of the shaft 200 will be described in detail. In other words, the variable inertia module 700 includes a body 710 having a hollow interior having a hollow interior as shown in FIGS. 2, 9, and 10, and a body 710 disposed to move freely within the body 710, When the rotation of the shaft 200 is stopped, the rotation of the shaft 710 reaches the center of the bottom surface of the body 710, and as the shaft 200 rotates and the speed increases, And a plurality of mass balls 720,

The reason for the fact that the inside of the body 710 of the variable inertia module 700 is in the shape of a light beam, that is, the wide shape is narrow and the narrow shape is downward, The inertia moment of the variable inertia module 700 is reduced by moving the bottom surface of the body 710 to the lower center of the body 710 so that the rotational speed of the shaft 200 is gradually increased, Each of the mass balls 720 gathered at the lower center of the body 710 moves in the outer radial direction inside the body 710 due to the centrifugal force inside the body 710, To increase the moment of inertia.

If the inside of the body 710 of the variable inertia module 700 is not partitioned and the mass ball 710 moves too far in the longitudinal direction of the body 710, And the rotation center of the variable inertia module 700 may be eccentric about the shaft 200, which may be an element that interferes with the rotation of the shaft 200. [ Inside the body 710 of the variable inertia module 700, the inside of the body 710 is partitioned so that the respective mass balls 720 can be uniformly placed along the circumference. 11, the body 710 of the variable inertia module 700 includes a plurality of partition walls 711 partitioning the interior of the variable inertia module 700 at equal radial intervals from the center of rotation, Each of the mass balls 720 of the body 710 may be filled with the same number of the internal spaces partitioned by the partition walls 711 of the body 710. The mass ball 720 is divided into the same number in each of the sections defined by the inner partition wall 711 of the body 710 and moves toward the inner center of the body 710 or moves in the radial direction, Eccentricity can be prevented.

The operation of the louver induction type wind turbine according to the present invention will be described in more detail with reference to FIGS. 3, 6 to 9, and redundant description will be omitted.

3, when the wind is not blown, the shaft 200 and the rotating body 400 are in a stopped state, and the louver 500 is rotated arbitrarily regardless of the wind direction. In addition, the mass balls 720 of the variable inertia module 700 are all gathered in the center of the body 710 so that the moment of inertia becomes small.

6 and 7, when the wind is blown from one direction, the leading edge is rotated so that each of the louvers 500 located in the direction of wind blowing is directed to the direction of wind blowing, It also rotates with a larger turning radius. The flow of wind passing through the louver 500 is directed to the rotating body 400 and the blades 410 of each rotating body 400 are rotated by the drag force together with the lifting force at the time of starting. The variable inertia module 700 can easily rotate the rotating body 400 and the shaft 200 in a state in which the moment of inertia is reduced and then the mass ball 720 is moved from the inner center of the body 710 to the outer radius Direction to increase the moment of inertia.

As the rotation of the rotating body 400 becomes larger, a swirling occurs in the swirling space portion 800 between the rotating body 400 and the shaft 200. The generated swirling swirls in the vortex guide plate 900 as shown in FIG. 8, To the upper portion of the rotation part 120 of the frame 100. [ At this time, the vortex in the vortex space portion 800 induces the wind to be sucked into the rotating body 400 more easily, and the louver 500 on the outer circumference of the rotating body 400 guides the wind flow In accordance with the wind speed. On the other hand, the louvers 500 on the opposite side of the louver 500 which winds the wind do not directly breeze but are fitted with winds through the rotating body 400, so that each of the louvers 500 rotates easily It can be discharged to the outside. 9, the inertial moment of the variable inertia module 700 is maximized so that the rotational speed can not be controlled to a large extent due to the rapid rotation of the rotating body 400 and the shaft 200, And the rotation speed of the shaft 200 can be limited, and the rotational speed of the shaft 200 can be kept constant to expect a constant rotational force.

When the rotating body 400 is rotated by the wind, the shaft 200 rotates. As a result, the rotation moment of the shaft 200 is received by the power generation module 600.

As described above, the louver induction type wind turbine according to the present invention includes a plurality of louvers 500 installed to be rotatable in the form of an airfoil, the wind flow being guided to the rotating body 400 according to the wind speed It is possible to rotate the rotating body 400 more efficiently at the time of starting after starting the rotation of the rotating body 400 from the start.

Particularly, when the rotational speed of the shaft 200 is increased through the variable inertia module 700 rotating together with the shaft 200, the moment of inertia is increased, and when the rotational speed of the shaft 200 is decreased, the moment of inertia is decreased The rotational speed of the shaft 200 can be limited to a certain level, and the rotational speed of the shaft 200 can be restricted to an excessive wind speed, thereby enabling power generation and efficient power generation.

In addition, the swirling space portion 800, in which the wind introduced between the shaft 200 and the rotating body 400 generates swirls, is formed to generate a suction force in the wind that flows into the rotating body 400, And the vortex generated in the vortex space portion 800 is guided to the upper portion of the rotation portion 120 of the frame 100 through the vortex guide plate 900 and is discharged to thereby smoothly flow the wind, .

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
