Description of the invention: [Technical field of the invention] The present invention relates to an aerodynamic automatic wind-tracking windmill, in particular to the use of aerodynamics to control the blade turning angle and automatically and easily face the wind direction, which is acceptable Unoriented wind energy, at the minimum wind speed (about 1-2 m / s), drives the shaft to generate electricity for the generator to achieve the best power generation efficiency, and the blade does not need another complicated flip structure, which can reduce the manufacturing cost. • [Previous technology] According to the fact that human beings continue to consume fossil fuels, and the stock of petroleum is decreasing, the emissions from combustion (3) 2 seriously cause the global greenhouse (warm) effect, so the UN actively regulates global warming. Various measures; today, all countries in the world attach great importance to and actively promote clean renewable energy technologies, and wind-power generation is currently one of the best solutions for humans to obtain renewable energy, because wind power has no fuel at all. C〇2 problem, there is no nuclear Φ energy waste radiation pollution problem. Electric energy is the so-called "advanced" energy. The use of electric energy is very extensive and is the foundation of modern human civilization. Therefore, modern human life cannot be short of electricity. The existing horizontal-axis wind turbines often have towers of more than a meter, and important generator sets and blades are located at the top of the tower. They are not only bulky and difficult to maintain, but also costly and unsatisfactory in construction. For patents on wind power generation, please refer to US Patent Nos. 4,496,283, 384,232, 440,266, 505,736, 685,774, 200846551, 830,917, 10,671,713, 4,453,703, 4,769,985, 4,810,180, No. 5,256,034, No. 4,220,870, No. 7,118,344, No. 6,749,399, No. 963,359, No. 5,269,647, No. 6,9,7, No. 6,537,018, No. 5,083,902, No. 6,674,393, No. 863,715, No. 4509899, No. 4421458, No. 6726439, No. 5195871, and No. 4245958, the above patents include at least the following defects: 1. The structure is complicated, the assembly is not easy, and the manufacturing cost is increased. 2. The action of the blade turning against the wind direction is not completely applied to the aerodynamic force. It requires additional complicated turning structures, such as the use of wind vanes and transmission mechanisms to link the blades. 3. The structure is not properly designed, so that the blade should be turned over to face the wind direction. The initial driving force of the flipping is large, and the blade cannot be turned over at low wind speed, so the efficiency of power generation is very low. Please refer to US Patent Nos. 3995170, 6688842, and 6674394, which are not fully effective for aerodynamics. These patents contain at least the following deficiencies: 1. Each blade is independently vertical and does not interlock with each other. To help flip (the case of No. 3995170 has a linkage, but the transmission mechanism is required to link the blades) "The starting force of the blade turning is very large. 2. If the blade is to be turned over (for example, flipped 180 degrees) to face the wind direction, the initial driving force of the inversion should be reported large, and the blade cannot be turned over at low wind speed. Therefore, the efficiency of power generation is low. 3. There is no proper material on the structure of the mother seal. For example, the lion wing piece is set to help the leaf raft to turn over. Please refer to US Pat. No. 4,383,801, which uses a large windmark to drive the cam to steer the blade. The patent contains at least the following defects: 1. The structure is complicated, the assembly is not easy, and the manufacturing cost is increased. The φ 2· mother blade uses the transmission of the mechanical structure to help the turning, so the starting driving force of the blade turning is large, and the blade cannot be turned over at low wind speed, so the efficiency of power generation is very low. • Read the Chinese patent No. 961·92·8, the blade turning system uses the wind mark to calibrate the wind direction, and the electronic signal is used to control the motor to flip the blade. The blade needs the servo motor to drive the whole process, which not only consumes electric energy, but also Electronic parts are prone to failure under the influence of climatic temperature and humidity. In addition, the motor is placed on the rotating parts, and the rotary joint is used for power transmission and transmission, which is very likely to cause malfunction. Please also refer to Chinese Patent No. 02232245.0, which contains at least the following missing points. 1. To make the blade turn over to face the wind direction, the initial driving force of the flipping is large, and the blade cannot be turned over at low wind speed. The efficiency of power generation is low. 2. There is no proper design for each blade structure, such as the provision of auxiliary fins to help the blade to flip, so the starting force of the blade turning is very large. 7 200846551 Therefore, it is known that the wind-inducing technique has not been treated as ideal, and the inventor has been thinking and researching deeply. After numerous design experiments, the invention has been produced. SUMMARY OF THE INVENTION The object of the present invention is to provide a windmill that automatically winds down the wind direction. The structure red includes the rotating shaft, the fan blade set on the service, and the fan blade includes the fan blade pivoted to the _, and the _ shaft abruptly confuses the fan The blade and the upper blade moment portion are larger than the blade lower blade moment portion, and the blade is provided with an auxiliary at the predetermined position, and the fin is provided on the blade assembly for stopping the blade when the blade is turned over; when the blade is subjected to the wind When it is windy, it uses the aerodynamic force to automatically and easily form the optimal smuggling and minimum wind resistance state respectively to receive the unoriented wind energy, thereby driving the rotating shaft to generate electricity at the minimum wind speed to achieve the best. The power generation performance 'and the blade does not require another complicated flip structure. The following is only a detailed description of the embodiments, and the detailed description of the present invention will enable the reviewing committee to have a better understanding and understanding of the functions and features of the present invention. [Embodiment] Referring to the first to third figures, the present invention includes a generator, a rotating shaft 20 disposed on the generator 10, a plurality of blade assemblies 30, and a support frame 40; wherein the blade assembly 30 is The blade 31 with two blades 32 is pivotally connected to the blade 20 of the rotating shaft 20' on the side of the rotating shaft 20, and is provided with an auxiliary turning knot. 8 200846551 The blade of the field is used for X wind and leeward. The force automatically and easily form the sew _ sigh minimum singularly, the female is not oriented for a few months b. This is the best power generation performance at the most wind speed. Hereinafter, the preferred embodiment will be described in detail: The generator 1G converts rotational mechanical energy into electrical energy. The rotating shaft 20 is erected on the generator 1G, and its rotation can be powered by the new motor 10. The fan blade assembly 30 has two upper and lower layers (the layer can also be used). The secret module is arranged on the rotating shaft 20, and can be combined with the topography and the wind field, and then superimposed upward to increase the power generation, and the interlacing is superimposed. The blade of the blade connected to the rotating side is provided with a bearing 311 at the pivoting end to reduce the damage rate, and the blade 32 is provided on the blade 31 of the rotating shaft 2 and the blade 31 is provided. The blade moment portion on one side of the core is larger than the other blade side moment portion of the shaft center. For example, the blade area A above the axial center of the blade shaft 31 is larger than the blade area under the axial center & the axial center of the blade shaft 31 is about the blade width. 2/3, and the 2/3 width of the leaf surface will face the wind direction so that the part faces the wind pressure more than the 1/3 width of the other side of the leaf surface, and the number of blades is turned into a nearly vertical shape, above which The lower side of one of the blades will be in contact with the upper side of the immediately adjacent blade 32; the blade 32 is provided with a first auxiliary flap 33 on the inner side. The flap has a predetermined angle, and the wind pressure of the cut-in can be gathered, so that the blade 32 has The moment of turning over, and the outer side of the blade 32 is provided with a second auxiliary fin 34, which is perpendicular to the blade 32 and can be gathered Wind pressure, to prevent wind pressure loss, and because the axis of rotation of the blade 32 is not in the center, a partial weight is added to the blade area a below the axis of the blade shaft 31 200846551 to balance the center of gravity of the blade 32 to the blade 31 axial center, so that the blade is balanced in a horizontal state, so that the blade 32 can easily flip the blade under the slight wind pressure under the breeze; the second auxiliary wing 34 is provided with the lift airfoil portion 341 conforming to the wing. When the blade 32 is turned to the horizontal level, an additional lift can be provided to assist the rotation of the shaft 2〇; to increase the stability of the blade rod 31, the blade assembly 30 is provided with a frame 35 for pivoting the two ends of the blade rod 31. A bearing 312 is also disposed at the pivotal portion, and the frame 35 is respectively provided with a stop portion 35 352 on the upper side and the lower side (or a stop portion on the shaft of the rotating shaft 2), so that the uppermost and lowermost blades 32 are provided. It can automatically lock the positioning when flipped to near vertical. The support frame 40 is used to support the rotating shaft 2〇, which is composed of a plurality of horizontal and vertical pillars 41, and each of the layers is provided with a cross-shaped pillar 42 provided with a bearing 44 at the parent fork of the pillar 42. The hole 43 is provided for the rotation shaft 2 to be rotatably and rotatable. Referring to the fourth figure, when the present invention is subjected to wind (the arrow represents the wind direction), the blade 32 of the upper blade assembly 3 is automatically turned into a vertical shape due to aerodynamic force, and the vertical blade 32 has the largest wind. The blade 32 on the other side is automatically flipped horizontally into a minimum windage state due to aerodynamic action, causing the blade assembly 30 to rotate counterclockwise to push the shaft 2〇; at this time, the lower blade assembly 30 is parallel to the wind domain. It loses the wind (loss of power), and the blades 32 on one side are horizontal, and the aerodynamic force is turned into a vertical shape. 200846551 Please refer to the fifth, sixth and seventh figures. When the upper and lower blade assembly 3G_ rotates counterclockwise, the lower blade assembly 30 is subjected to the horizontal blade 32 (fan blade). The assembly 3 is perpendicular to the other side of the blade 32 and begins to be subjected to aerodynamic force. The first auxiliary slab is subjected to the wind pressure of the plunging cut, and the blade area on the axial side of the blade shaft 31 is larger than the axial center. The side blade area' acts as a counterweight of the blade 32, and has a better torque action so that the horizontal blade 32 automatically flips upwards automatically, and when the number of blades 32 is turned over, the mosquitoes will be stuck, and the red and the lowermost ones - The blade 32 will contact the stop portion 35 352 to form an automatic locking. At this time, the vertical surface formed by the number-blade 32 can form an optimal wind receiving surface, and the effective air pressure of the second auxiliary wing piece 34 is used to Push the shaft 20. See Figure 8 for the number of blades on the % side of the upper blade assembly. • When the leeward state is in the leeward state, in addition to reducing the wind resistance, the second auxiliary wing 34 is formed vertically downward. The second auxiliary flap 34 can obtain an upward lift according to the aerodynamic principle, thereby forming a turning force to assist the rotation of the blade assembly 30 toward the axis of the shaft 20. Referring to the nineth and tenth figures, the seventh figure is connected. When the wind blade layer assembly 30 is turned into a vertical surface, the other side of the blade assembly 30 is originally vertical. The blade 32 starts to be typhoon-like, because the blade area on the axial side of the blade shaft 31 is larger than the blade area on the other side of the axis, and has a better moment action, so that the vertical blade 32 is automatically flipped into a horizontal shape. , to become the minimum wind resistance state. As shown in Mingfen's Dijon®, when the vertical blade of the lower blade assembly 30 is subjected to the maximum wind pressure, the horizontal blade of the lower blade assembly 3 is in the leeward state, which can be (10) into the minimum brewing state; The blade assembly 3 is parallel to the wind direction 'which loses wind pressure (loss of power), while the lower blade assembly 30 receives the rotational power of the upper blade assembly 3 . Please read the twelfth figure 'When the lower blade assembly 30 continues to rotate by the wind', the upper layer 3G enters the windy state, causing the blade 32, which was originally horizontal, to be turned into a vertical shape, (4) The blade 32 which is originally vertically formed is turned horizontally by the leeward, so that the upper blade assembly 30 can be rotated, so that the wind energy can be received, thereby driving the shaft 2 at a minimum wind speed. 〇 Make the generator 1 〇 generate electricity to achieve the best power generation performance. As shown in Fig. 13, the number of ribs 321 ' may be provided on the surface of the blade & of the present invention to increase the structural strength thereof and to effectively collect the wind pressure. ▲The above are the examples given in this case, which are only for the convenience of explanation. When this is not the case, the meaning of the case is limited, that is, the various transformation designs that are based on the scope of the listed patents should be included in the scope of the case. in. 12 200846551 [Simple description of the drawings] The first figure is a perspective view of the present invention.
