New description: [New technical field] In more detail, it is a wind turbine with vertical multi-level wind turbines. [Prior Art] • The principle of wind power generation is simply to convert the wind energy into a machine through the wind energy, and the 'Ml motor converts the machine into a Wei, and uses the f battery to store it. Therefore, the φ wind turbine mainly includes two parts: the wind wheel and the generator. The wind wheel can be divided into horizontal and vertical according to the relative position of the horizontal plane of the spindle disk. The midnight experiment and research showed that the wind utilization rate of the horizontal wind turbine was about 23°/ under the condition that the wind wheel was equal in area. ~29% or so and the vertical type can be made above. In terms of starting wind speed, the starting of the horizontal wind wheel is already the current consensus.
動性能相對而言是較差的，但是若改良設計，只要翼型和安裝角選擇合適， 則可以改善這_題。在結構特點方面，水平式風輪的葉片錢轉一周的 過程中’受慣性力和重力的综合作用，慣性力的方向是隨時變化的而重 力的方向則始料變’這樣葉片所受的就是―個交變載荷，這對葉片的疲 勞強度是非常不·。水平式風輪的發電機制於風力強，風速快的場域， 因此都置於幾十麵高空，這使發電機的安裝及維修非常不便。垂直轴風 輪的葉片在旋轉的過程中受力情況要比水平軸好得多，由於慣性力與重力 的方向始終不變，所受的是一恆定載荷，因此疲勞壽命要比水平式長，同 時’垂直軸的發電機可以放在風輪的下部或是地面，便於安裝維護。 雖然風力發電機號稱是清潔能源’能起很好的環保作用，但是隨著越 3 M403559 =越夕二型風電場的建立，—些由風力發電機引發的環保問題也凸顯出 ★疋本s問題’二是對當地生態環境的影響。水平轴葉片的尖速比一 又 左右，在這樣的高速下葉片切割氣流將產生很大的氣動噪音，鳥 類在乂樣的w速葉片下也报難幸免。垂直式的尖速比則比水平轴小得多， 矣勺1 ·5〜2 、丄Dynamic performance is relatively poor, but if the design is improved, this problem can be improved as long as the airfoil and mounting angle are chosen appropriately. In terms of structural characteristics, the blade of the horizontal wind wheel is converted into one week by the combination of inertial force and gravity, the direction of the inertial force is changing at any time, and the direction of gravity is changed. ―An alternating load, which is very bad for the fatigue strength of the blade. The generator of the horizontal wind wheel is made in a field with strong wind power and fast wind speed, so it is placed at dozens of planes, which makes the installation and maintenance of the generator very inconvenient. The blades of the vertical axis wind wheel are much better stressed than the horizontal axis during the rotation process. Since the inertial force and the direction of gravity are always the same, they are subjected to a constant load, so the fatigue life is longer than the horizontal type. At the same time, the 'vertical axis generator can be placed on the lower part of the wind wheel or on the ground for easy installation and maintenance. Although the wind turbine is said to be a clean energy source, it can play a very good environmental protection role, but with the establishment of the 3 M403559 = the Lunar New Year wind farm, some environmental problems caused by wind turbines are also highlighted. The second problem is the impact on the local ecological environment. The tip-to-speed ratio of the horizontal-axis blades is about one to another. At such high speeds, the blade cutting airflow will generate a lot of aerodynamic noise, and the birds are also difficult to survive under the w-like blades. The vertical tip speed ratio is much smaller than the horizontal axis, and the spoon 1 · 5 ~ 2, 丄

From the air force knife, the faster the object speed, the greater the influence of the shape on the flow field. When the wind turbine is running outdoors, the breeze is inevitably contaminated, which actually changes the shape of the blade. In the case of the κ flat wind wheel, such a small shape change will greatly reduce the wind energy utilization rate. The vertical type is not so sensitive to the change in shape due to the low speed, and the aerodynamics of the wind wheel are not affected. Based on the above analysis, the advantages of vertical wind turbines are more than horizontal, and the application fields of wind turbines are also more extensive. [New content] Based on the comparison of horizontal and vertical wind wheels in the prior art, in the case of more niche conditions of the vertical wind wheel, the people invited to develop the improvement of the vertical wind wheel, especially the wind. This utilization and starting performance are two parts. The purpose of the present invention is to provide a vertical multi-stage wind turbine wind turbine having the effect of increasing the wind receiving area and increasing the utilization of wind energy by the multi-stage wind wheel. The purpose of the present invention is to provide a vertical multi-stage wind turbine wind turbine having the effect of increasing the starting performance with a multi-stage wind wheel and being able to operate in a low wind environment. The purpose of this case is to provide a vertical multi-level wind turbine wind turbine. Although the wind area is increased by 4 M403559 level wind turbines, the airflow cutting effect does not increase with the wind area. The knives are placed on each of the blades of the tier, and based on this, the flank 9 produced by cutting the airflow does not increase. The purpose of this case is to provide a vertical type multi-level wind turbine with a multi-level wind wheel that constitutes a southerly center with a center of gravity, so that the wind wheel can operate stably. * The implementation technology for achieving the above objectives in this case is mainly to provide at least two levels of wind wheels on the vertical axis of the rotor of the generator-driven wind turbine. _ [Embodiment] In order to facilitate the description of the present invention, the central idea expressed in the above-mentioned summary of the invention is expressed by the embodiment. The implementation of various kinds of different tactics, treasury, deformation, or displacement W, _ coffee rights, suspicion. In the following description, similar elements are denoted by the same reference numerals. As shown in the first figure to the figure, in this case, the wind power of the multi-layered wind wheel «, which is on the rotating shaft of the rotor of the driving power generator motor, is set at least two layers of wind repairing each layer of the wind wheel 2 bag ~ A plurality of blades (3 to 5) of blades 21 are provided, each of which has a wind-cut angle of one. In this filial piety, the wind wheel buckles are in four levels, and each stage of the wind wheel has a wind receiving distance D between the blades so that the blades do not interfere with each other. As in the first and second figures, the blade 21 is of a single blade type having a flat windward face 22 and a leeward face 23. At the bottom of each blade 21, there is provided an auxiliary operation device (4). The rotation assisting device 24 is a means for adding centrifugal force to increase the rotational inertia of the material 21, and the r-plate and the rotary motion of the crucible 1 are smoother, and the wind is smooth. This steady and continuous operation can be achieved by turning the rate. In the tree embodiment, the auxiliary operating device 24 includes - 5 M 403 559 "the struts Μ 1 of the L-longitudinal relationship of the stalk 21 and the slidable 242 13⁄4 stalks provided on the struts The end is fixed to the rotating shaft 1〇, and the other end is fixed to the blade 2 [the two ends of the supporting rod 241 are respectively provided with the 'buffering member 25. When the blade 21 is rotated by the wind, the weight 241 is caused by The centrifugal action & μ # t phase slips from the inner side of the blade 21 toward the outer side of the blade 21, increasing the centrifugal force of the operation of the blade 21. As in the first and fourth figures, the blade 3 is folded. The movable type is composed of two leaf slabs mu on the side edge of the movable money structure 34 4 mesh connection; each of the wires 32 33 has a city face % and a leeward face 36. When the windward face 35 receives wind, (four) the leaf plate 32 33 open to - maximum opening angle; when the leeward surface 36 is subjected to wind, 'the two blades 32 33 are relatively closed to - the minimum closing angle. The maximum closing angle is greater than 9Q degrees less than (10) degrees, the optimum value is警度度。 The most m angle is greater than 20 degrees less than 9 degrees, the best value is 45 degrees. In this embodiment, the same level The sheet 31 has a continuous opening and contraction due to the action of the wind and the leeward. In this case, the multi-level wind wheel has a shape of a smoke (four) sheet, but the present invention does not exclude that a plurality of levels of the wind wheel use different leaves > The possibility of shape. It is known that the wind power is compared with the area of the wind, and the wind turbine with the record wheel is 'windy _ fresh level ^ big, the wind can be more, wind energy Xiang The rate increases. In this case, the level of the wind wheel keeps the wind distance D that does not interfere with each other's operation. This wind is kept at a good chaotic edge. The H's force cuts the _ recorded # on the hemp, from the space to pass through The wind energy loss is reduced, so the wind energy is increased, and the start of the wind wheel is increased. This can be used to resent the anger and the effect of the abalone. In addition, this creation is a gradual wind. The increase of the wheel is affected by the accumulation of the wind, but the airflow is not increased by the increase of the wind area, but the object is distributed on every level, based on this, the cutting airflow 6 M403559 type blade, multi-level, wind wheel The sound that can be stabilized when subjected to wind will not increase. The wind turbine system in this case uses the board. The wind wheel constitutes the center of mass of the entire windmill, so that it has a stable rotation of the center of gravity and reduces the situation of shaking. Although the case is illustrated by two preferred embodiments, the skilled person can not deviate from the spirit of the case. The above-mentioned embodiments are only used to illustrate the case. However, it is not intended to limit the scope of the case. Any modification or change that is not in violation of the spirit of the case is a patent application scope.
