Rotor structure [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotor structure, and more particularly, to a rotor structure that generates rotational force by wind and is connected to a power generation module of a wind power generator to transmit a rotational force.

As is well known, hydroelectric power generation, thermal power generation and nuclear power generation require large-scale power generation facilities, and thermal power generation requires a large amount of fuel (for example, energy such as oil or coal) In order to solve this problem, wind power generation, which is a power generation method that does not need any additional fuel, is emerging as an alternative.

The above-mentioned wind power generation is one of the economical generation methods by pollution with the generation of solar energy, wave and tidal power generation, and refers to a power generation system utilizing wind power.

In the case of power generation using wind power, there is an advantage that there is no waste, and since the power is generated by turning the main shaft of the generator by using a propeller type impeller, the structure and rotation performance are evaluated in a propeller type impeller (also called a blade or a rotary).

Thus, the vane unit 220 located at the uppermost end can be made to have a high resistance to the wind force.

10 is a schematic external perspective view showing the rotation connection part 300. As shown in FIG.

10, the rotation connection part 300 includes a rotation axis insertion part 310 into which the rotation axis 100 is inserted, and a rotation axis insertion part 310 connected to the rotation axis insertion part 310 and the wing unit 220, The rotation shaft insertion part 310 includes a body part 312 connected to the rotation shaft 100 and a support part 330 extending from the body part 312 to support the unit 220. [ A wing unit 220 extending from the body 312 and connected to the wing unit 220 to fix the wing unit 220 at a predetermined position, And may include a fixing portion 316.

The body portion 312 may have a cylindrical shape having an interlocking hole for interlocking with the rotation axis 100. The rotation axis 100 may be inserted into the interlocking hole of the body portion 312, And may be coupled to the coupling hole using a coupling element such as a bolt (not shown) and interlocked with the rotary coupling part 300. However, interlocking of the rotary connection part 300 and the rotary shaft 100 is not limited thereto.

As described above, each of the plurality of vane units 220 may be connected to each other to form a spiral, but the present invention is not limited thereto. That is, the vane unit 220 may not be an essential component of the vane module 210, so that the vane module 210 may not be formed by connecting each of the vane units 220.

11 is a schematic external perspective view showing the rotation axis inserting portion 310 with reference to the fixing portion 316. As shown in FIG.

11, the fixing portion 316 may protrude outward to prevent the connection failure due to the support portion 330 when the vane unit 220 is connected. Since the weight of the rotor structure 10 of the present invention should be small, the components constituting the rotor structure 10 of the present invention must be lightweight and small in size. Since the operation of connecting the vane unit 220 to the fixed portion 316 may require a high level of working ability, when the fixed portion 316 protrudes outward, Lt; RTI ID = 0.0 > 316 < / RTI >

The fixing unit 316 may be spirally protruded so that the vane unit 220 is helically fixed. The fixing unit 316 may be directly connected to the vane unit 220. Therefore, the shape of the fixing portion 316 may be a shape corresponding to the vane unit 220. This is because the wing unit 220 can be stably connected to the fixed portion 316 as the connection area where the fixed portion 316 and the wing unit 220 are connected becomes larger, Which has a shape corresponding to that of the portion connected to the connecting portion 220.

In addition, the fixing portion 316 may have a larger cross-section than a cross section of the fixing portion 316 contacting the body portion 312 along the axial direction, which is not in contact with the body portion 312. Since the wind force transmitted from the vane unit 220 to the fixed portion 316 is transmitted to the body portion 312, the fixed portion 316 has a large durability May be required. Therefore, the fixing portion 316 may have a larger cross-section in contact with the body portion 312 along the axial direction, so that the durability of the fixing portion 316 may be increased.

12 and 13 are schematic exploded views showing that the vane unit 220 is coupled to the rotation connection part 300.

12, the vane unit 220 connected to the fixing portion 316 and the fixing portion 316 has an inner penetrating portion H1 through which a fastener such as a nut passes, The inner penetrating portion H1 is formed on the upper side and the lower side of the support portion 330 with respect to a plane perpendicular to the rotary shaft 100 so that the penetration failure due to the support portion 330 when the fastener passes . Thus, the vane unit 220 can be easily connected to the fixing portion 316.

13, the inner penetrating portion H1 formed in the vane unit 220 can be formed in different vane units 220. [

In addition, a plurality of the rotation connection portions 300 are disposed apart from each other along the axial direction, and at least one of the rotation connection portions 300 has a fixing portion 316, And can be connected to the two neighboring vane units 220. The fixing part 316 is connected to the two wing units 220 so that the wind force can be transmitted from the wing unit 220 to the body part 312 and the connection between the two wing units 220 .

In addition, a plurality of the rotation connecting portions 300 are disposed apart from each other along the axial direction,

At least one of the fixing portions 316 of the rotary connection portion 300 may be connected to the single wing unit 220. For example, the fixing portion 316 of the rotary connection portion 300 located at the upper end of the blade unit 220 located at the uppermost end of the blade unit 220 is connected to the blade unit 220 located at the uppermost position . Thus, the blade unit 220 located at the uppermost end can be made to have a high resistance to the wind force.

FIG. 14 is a schematic external perspective view showing the rotation shaft insertion portion 310 with reference to the mounting portion 314. FIG.

14, the mounting portion 314 may have a cross section that is in contact with the body portion 312 along the axial direction, which is larger than a cross section of the mounting portion 314 that is not in contact with the body portion 312. [ Since the wind force transmitted from the vane unit 220 to the mounting portion 314 is transmitted to the body portion 312 again, the mounting portion 314 needs to have a large durability in a region in contact with the body portion 312 . Therefore, the mounting portion 314 may have a large cross-section in contact with the body portion 312 along the axial direction, so that the durability of the mounting portion 314 may be increased.

The mounting portion 314 may support the support portion 330 such that at least one side of the support portion 330 is exposed to the outside. That is, the supporting part 330 may be connected to the mounting part 314 in a direction in which the supporting part 330 is exposed to the outside. Thus, since the support part 330 can be easily connected to the wood part, it is possible to reduce the assembling time of the worker, and the weight of the mounting part 314 can be reduced.

15A is a schematic sectional view showing that the support portion 330 is seated on the mounting portion 314 and FIG. 15B is a schematic enlarged view showing the tolerance compensation space S2.

15 (a) and 15 (b), the support portion 330 is formed by forming a clearance compensation space S2 between at least one of the first side portion 314b and the second side portion 314c So that it is possible to prevent the interference fit due to manufacturing tolerances when entering the seating space S1. A tolerance may be generated depending on the working environment when manufacturing the support portion 330. The support portion 330 may have a problem that the support portion 330 or the mounting portion 314 is damaged when the support portion 330 is constrained to the mounting portion 314 Lt; / RTI > Therefore, the support portion 330 may be formed to define the tolerance compensation space S2. However, the size of the tolerance compensation space S2 is not uniformly determined, and may be variously modified according to the intention of a person skilled in the art.

[ If the width of the engaging portion 334 is smaller than the width of the radius adjusting portion 332, the engaging portion 334 is damaged due to a process of connecting to the mounting portion 314 or an external force . The width of the coupling portion 334 may be the same as the width of the radius adjusting portion 332 and the width of the coupling portion 334 may be greater than the width of the radius adjusting portion 332. [ It may be big.

In addition, the radius adjusting portion 332 and the engaging portion 334 may have different cross sections along the rotation axis 100. For example, the radius adjusting portion 332 may be elliptical in shape so as to minimize the resistance to the wind force, but the engaging portion 334 may be formed in the seating space 314 so as to be efficiently seated in the seating space S 1 of the mounting portion 314. May be a shape corresponding to the space S1. Therefore, the radius adjusting portion 332 and the engaging portion 334 may have different cross-sections.

However, the number of the outer penetrating portions H2 is not fixed, and can be variously changed according to the intention of a person skilled in the art.

FIG. 19 is a schematic side view showing that the rotation connection part 300 is connected to the rotation shaft 100.

As described above, each of the plurality of vane units 220 may be connected to each other to form a spiral, but the present invention is not limited thereto. That is, the vane unit 220 may not be an essential component of the vane module 210, so that the vane module 210 may not be formed by connecting each of the vane units 220. In this case, the wing part 200 includes the wing module 210, and the rotor structure 10 of the present invention may be formed by mounting the wing module 210 on the rotation connecting part 300. Therefore, the idea of the present invention is not limited to the formation of the wing module 210 by connecting each of the plurality of wing units 220.

19, a plurality of the rotation connection portions 300 are disposed apart from each other along the axial direction, and the separation distances K1 and K2 between the rotation connection portions 300 are determined based on predetermined conditions. . The predetermined condition may mean the number of the wing modules 210, the number of the rotation connection parts 300, the size of the wind power where the rotor structure 10 of the present invention is installed, and the like.

The rotation connection part 300 may be disposed on the rotation shaft 100 based on the predetermined condition that at least one of the separation distances K1 and K2 is different from the rest. For example, if the rotor structure 10 of the present invention is installed with a large amount of wind force below the upper portion of the wing module 210 along the axial direction, 300 may be disposed on the rotary shaft 100 such that the separation distance K1 is smaller than the remaining separation distance K2.

The rotation connection part 300 may be formed by connecting the rotation connection part 300 located at the uppermost or lowermost end of the rotation connection part 300 to the rotation connection part 300, And may be disposed on the rotary shaft 100 based on conditions. The wing unit 220 located at the uppermost end of the wing unit 220 is connected to the wing unit 220 adjacent to the lower side only and the wing unit 220 located at the lowermost end of the wing unit 220, The wing unit 220 is positioned at the uppermost and lowermost positions in comparison with the vane unit 220 except for the vane unit 220 located at the uppermost and lowermost positions in that the vane unit 220 adjacent to the upper side is connected. This is because the vane unit 220 has a force that can resist the wind force.

The rotation connection portion 300 may include a separation distance K2 excluding a separation distance K1 between adjacent rotation connection portions 300 from the rotation connection portion 300 located at the uppermost or lowermost end of the rotation connection portion 300, May be arranged on the rotation axis 100 based on the predetermined condition. This makes it easy to connect the rotary connection part 300 to the rotary shaft 100.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be apparent to those skilled in the art that changes or modifications may fall within the scope of the appended claims.
