Description

Rotation apparatus for wind power generator

The present invention relates to a rotating device for a wind power generator, and more particularly, in order to obtain the power used for a generator in a wind power plant, when the wind is converted into rotational force without being influenced by the direction of the wind and minimizing the resistance to the reverse wind. And because the wind is subjected to the direct pressure of the rotary device is high energy conversion efficiency, and relates to a wind turbine generator for easy installation and maintenance.

Fossil energy, such as petroleum and coal, is a major cause of finite resources and environmental pollution. Therefore, the development of pollution-free and clean energy is required. As a clean energy source, solar heat, wind power (wind power), tidal-difference car, and bioenergy are being studied. Especially, energy from wind power has been used in mills for a long time. By using the rotational energy is obtained from the wind power, and using the rotational energy to operate the generator to obtain the electrical energy.

Wind power generation (wind power generation) is a power generation method that rotates the windmill (wind) by the wind of nature, using a gear mechanism to increase the speed to turn the generator. Since the wind turbine needs to rotate the blades, improvements such as changing the inclination and shape of the windmill blades are made according to the wind speed.

In addition, wind power generation is not possible when there is no wind, so a battery or diesel generator is often installed to avoid a power outage. In this case, however, direct current generation occurs, and the capacity is about tens of watts to tens of kW. Large-scale wind farms have large windmills and are difficult to deal with during storms, some of which exceed 1,000 kW in the United States. Germany, which now has 643 MV of windmills, doubled its power generation capacity in 1994 and is spurring practical use as alternative energy.

Windmills typically include savonius windmills and Darius windmills. Savonius windmills are simple in structure, robust, and have strong torque, so they can be maneuvered on their own, and are not restricted by the direction of the wind. On the other hand, it is difficult to be used in a windmill for power generation because it is difficult to rotate at high speed due to structural problems.

In addition, Darius windmills are relatively strong in mechanical strength and are not restricted by wind direction, and have high advantages in proportion to the input energy. On the other hand, there is a disadvantage that a separate starting device must be added at low wind speeds because the torque is weak and cannot start by itself.

On the other hand, propeller-type windmills can be self-starting at low wind speeds and at high wind speeds, so they are ideal for wind energy use. As such, there are problems that only a small number of regions are used under geographical conditions with severe wind direction and wind speed changes.

The present invention has been made to solve the above problems, an object of the present invention is not affected by the direction of the wind when converting the wind into rotational force to obtain the power used in the development of the wind power generator, Its purpose is to provide a wind turbine rotating device with high energy conversion efficiency and easy installation and maintenance because it minimizes resistance and allows wind to be subjected to direct pressure.

Wind turbine generator of the present invention for achieving the above object, the lower side is rotatably fixed by the coupling and the coupling is installed at a 120 ° angle to the outer peripheral surface of the rotary shaft, respectively, a plurality of horizontal installation And a plurality of operating plates which are operably coupled to the fixing bar by the fixing bar support, and having a protrusion on the lower side toward the front, supporters for fixing the protruding end of the fixing bar, and a rotating shaft. And a blocking shaft in contact with the lower side protrusion of the operating plate installed at the lowermost portion of the operating plate to block movement of the operating plate.

According to another feature of the present invention, the fixing bar of the rotating device has an elliptic curved shape, and the operation plate also has an elliptic curved shape.

Hereinafter, with reference to the accompanying drawings will be described in detail a rotary device for a wind turbine of the present invention.

1 shows an embodiment of a rotary device 10 according to the present invention and a power generation device constructed using the same.

Rotating device 10 of the present invention is installed to be exposed to the upper side of the base 111, the generator 112 for generating electricity by the rotational force generated by the rotating device 10 in the base 111; Is installed. The generator 112 has a gear 110 coupled to the rotating shaft, and the gear 110 is engaged with the gear 109 coupled to the rotating shaft 101. The gear 109 coupled to the rotating shaft 101 may have a larger diameter than the gear 110 connected to the generator 112 so that the gear 109 may be rotated at a high speed even at a low speed rotation of the rotating shaft 101, thereby increasing power generation efficiency. .

Base 111 is installed on the ground or as shown below the ground surface. It is highly stable to install below the surface, but there is a disadvantage that the installation cost more.

In the rotary device 10 protruding to the upper part of the base 111, the rotating shaft 101 is installed through the center of the base 111 by using the coupling 108. The lower portion of the rotating shaft 101 extends through the coupling 108 and protrudes, and the gear 109 is arranged at the protruding end. Therefore, the gears 109 and 110 are linked to each other by the rotation of the rotary device 10 to supply power to the generator 112. In order to facilitate the rotation of the rotating shaft 101, a bearing (not shown), which is a general mechanical element, is installed on the coupling 108 and the base 111.

A plurality of fixing bars 102 are coupled to the rotating shaft 101 in the horizontal direction while being supported by the support 106, and a hole having a thread formed therein in the horizontal direction is formed on the rotating shaft 101, and the fixing bar 102 is fixed to the rotating shaft 101. It is also possible to form a screw thread on the outer circumferential surface of) and to combine by screwing, or by pressing. The fixing bar 102 has a straight or semi-ellipse (or curved) shape and will be described later.

Opposite ends of the fixing bars 102 are coupled to the support 106 to which the fixing bars 102 are coupled. The support 106 is also coupled to the fixing bar 102 by screwing or press-fitting. As described above, the fixing bar 102 is fixed at one end to the rotation shaft 101 and the other end is coupled to the support 106.

In the figure, the support 106 is shown in the inclined shape of the upper side, the connection state of the support 106 can be changed depending on the place where the rotary device 10 of the present invention is installed. In other words, in consideration of the balance between the wind power and the weight of the rotary device 10 is to be able to adjust the weight of the rotary device 10 so that the optimal efficiency can be exhibited in the place where the rotary device 10 is installed.

This shape is to provide flexibility of the shape deformation according to the wind generation state of the terrain on which the rotary device 10 is installed.

Each of the fixing bars 102 coupled to the rotating shaft 101 are spaced apart from each other by maintaining a constant interval, and the fixing bars 102 are fitted with a plurality of operating plates 103, and the operating plates 103 are The fixing bar support part 104 is formed on the upper side, and the fixing bar 102 is inserted into the fixing bar support part 104 of the operation plate 103.

At this time, since the fixing bar 102 is loosely coupled to the inside of the fixing bar support portion 104, the operating plate 103 is operably installed around the fixing bar 102, so that the wind blows the operating plate. 103 is a shaft to operate the fixing bar 102 in accordance with the direction of the wind.

When the wind blows, the operation plate 103 serves to rotate the rotation shaft 101 by the pressure of the wind. The operation plate 103 rotates only in one direction and is blocked by the fixing bar 102 fixed to the lower portion, so that the operation plate 103 cannot be rotated in the opposite direction.

The operating plate 103 can be easily operated by the force of the wind and should not be broken by the wind, it is preferable to be made of an aluminum plate which is a metal suitable for this purpose.

In addition, even when the rotating device 10 is damaged, since the operation plate 103 is easily separated and coupled, the installation is easy, and by replacing only the damaged part, there is an advantage that normal operation is possible. Furthermore, since the size of the operating plate 103 can be adjusted according to the size of the rotating device 10, the size can be flexibly applied according to the installation place.

2 is a plan view seen from the upper side of the rotating apparatus 10 and the base 111.

As shown, it can be seen that the fixing bars 102 extend radially about the rotation shaft 101. In addition, the angle between the fixing bar 102 is arranged so as to maintain about 120 ° protruding in three directions.

Such a three-way arrangement has the advantage that the rotation shaft 101 can be rotated even if the wind blows in any direction without regard to the direction of the wind. At this time, if the direction of the wind rotates the rotating shaft in the opposite direction with respect to the forward rotation of the rotary shaft 101 (the direction of rotation of the generator to generate power) there is no fixed bar 102 that can block the rotation because the operating plate While the 103 is operated in a horizontal state, rotation by the wind force is blocked. Therefore, rotation of the rotation shaft 101 in the opposite direction is prevented. This is more efficient than installing the reverse blocking member on the rotating shaft 101, the blocking effect can be doubled by using in parallel with the reverse blocking member.

3 and 4 shows the coupling state of the operation plate 103 and the fixing bar 102 in detail. The operating plate 103 has a fixed bar support portion 104 is formed on the upper side, the lower portion is formed with a protrusion 105 bent toward the front. The lower protrusion 105 is a part in contact with the upper side of another operating plate 103 installed on the lower side of the operating plate 103. The protrusion 105 maintains close contact with the lower operation plate 103.

The protrusion 105 extends to cover the fixed bar 102 coupled with the operation plate 103 positioned on the lower side of the protrusion 105, so that the operation of the operation plate 103 is blocked when the wind blows in the forward direction. do. As described above, the operation plate 103 whose operation is cut off serves as a wall, and the rotating shaft 101 rotates by the force of the wind blowing on the wall.

4 is a side view of the operating plate 103 of FIG. 3, in which an fixing bar 102 is operably installed by the fixing bar supporting part 104, and a protrusion 105 having a bent shape is formed on the lower side. Able to know. The fixed bar support portion 104 has a shape that protrudes by forcibly pressing out of the plane of the operating plate 103 after cutting a portion of the operating plate 103.

This is advantageous in that the fixing bar 102 can be easily installed without using a separate member to operably support the fixing bar 102. In addition, it is apparent that the fixing bar 102 can be installed by using a separate mounting member such as a bracket having a screw fixing hole at both ends and a middle portion bent in a semicircular shape.

7 and 8 further discloses the structure of another embodiment of the fixing bar 102 and the automatic plate 103 according to the present invention.

Referring to FIG. 7, the fixing bar 102 has a semi-elliptic shape in a conventional straight shape. The semi-elliptic shape is a structure that can collect the wind better, there is an advantage that the rotation efficiency is increased. Since the fixing bar 102 has a semi-elliptic shape, the shape of the operating plate 103 can be changed accordingly.

One embodiment of the operating plate 103 is shown in FIG. 8. This is made of a slightly curved form to give the same bending as the fixing bar 102 is also bent, it is preferable that only one fixing bar support portion 104 is installed at the center of the top so as not to flow slightly, which is the operating plate ( While the 103 is in operation to reach the fixed bar 102 is made so as not to interfere with the operation.

If the operating plate 103 is not in contact with the curved fixing bar 102 can form a number of fixing bar support 104, it is designed according to the curved state of the curved fixing bar 102, the operating plate as shown Insert 103 to the fixing bar 102 so as not to leak the wind as closely as possible. All the operation plates 103 are inserted to be installed so as not to move left and right in close contact with each other.

The state of the installed operating plates 103 exhibits the same deflection as the fixed bar 102 on the plane as shown in FIG.

As another embodiment of the operation plate 103, the use of a rectangular operation plate 103 is possible. This is accomplished by reducing the width, not the vertical length, of the operating plate as shown in FIG. 3, and inserting and engaging a larger number of operating plates into the curved fixing bar 102 (shown in FIG. 7). At this time, the width of the operating plate 103 is preferably set to a length that can occupy the shortest straight distance along the fixing bar 102. By installing to have such a condition, the bending of the fixing bar 102 and the bending by the operating plates 103 may have the same shape. Of course, in the case of a rectangular operation plate, a large number of operation plates are required. The size and the degree of warpage of the operating plate 103 is variable according to the size of the rotary device 10 according to the present invention.

The operating plate 103 as described above may be formed to insert the fixing bar 102 in the form of the fixing bar support portion 104 as shown in FIG. In this case, of course, the deflection in the form as shown in Fig. 8 is obvious.

5 and 6 is an operating state diagram of the rotary device 10 according to the present invention, respectively. Since the operating state of the rotating device shown in Figures 2 and 7 are the same, the following description will be made using the rotating device 10 of FIG.

5 is a state of the operating plate 103 in the case of blowing a pure wind, that is, a wind that can rotate the rotating shaft 101. When the wind blows as shown by the arrow, the operating plate 103 maintains a vertical state in the same direction as the rotation shaft 101. This is the same as when the wind is not blowing. Even if the wind continues to blow, the operation plate 103 is in close contact with the upper side of another operation plate 103 located at the bottom and no longer rotates. This is because the protrusion 105 at the lower portion of the operating plate 103 is blocked by the fixing bar 102 that fixes the lower operating plate 103. The operating plate 103 located at the bottom is blocked by the blocking shaft 107 so that all the operating plates 103 serve as walls as the vertical state.

Therefore, in the case of pure wind, all the operation plate 103 serves as a wall, the operation plate 103 subjected to the reverse wind flows while listening to the wind to minimize the resistance generated in the forward rotation, the operation plate is generated a rotational force ( The force of the wind acting on 103 is transmitted to the rotating shaft 101. Therefore, the rotation shaft 101 converts the force of the wind into the rotational force.

That is, as shown in Figure 6, when the reverse wind is blown, the operating plate 103 has no rotation preventing means (fixing bar 102 and the blocking shaft 107 in Figure 5) due to the force of the wind The operation plate 103 is horizontal while being lifted and all of the wind passes. Therefore, since no force is transmitted to the rotating shaft 101 that resists forward rotation, the rotation force is not generated. The rotating device 10 as shown in FIG. 7 has a higher efficiency of collecting wind.

By using the rotary device 10 according to the present invention it is possible to configure the power generation system as shown in FIG.

As described above, according to the present invention, the conversion efficiency of the energy is high and the installation and maintenance are easy because the wind power is not affected by the direction of the wind when the wind power is converted into the rotational force to obtain the power used in the power generation of the wind power generator.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such variations or modifications will belong to the appended claims. .
