New description: [New technical field] This creation is about a wind power generation device that automatically adjusts the windward angle of the leaf surface. In particular, the size of the σ wind is automatically adjusted to the angle of the blade to facilitate the start of the breeze. Wind and instantaneous gusts can maintain stable power output. It is a wind and car with good wind blade function, which is beneficial to the wind power generation device used in power generation function. [Prior Art] • Since the discovery of electrical energy, human beings have experienced rapid growth in material civilization and have greatly improved human life. However, with the advancement of life, human beings are increasingly demanding electrical energy, and existing generator systems are unlikely to develop indefinitely, so alternatives must be sought to address human demand for electrical energy. At present, the most common method of power generation technology known to man is to burn petroleum. This method is limited by the combustion principle. It not only consumes fuel quickly, but also produces a large amount of waste gas and waste heat, which seriously affects the living environment. Moreover, oil is limited to a few countries and has limited capacity. It will not be used for a long time. — To this end, countries are actively pursuing alternative energy solutions that not only require these alternative energy sources to replace oil, but more importantly, to seek a new, pollution-free source of energy. Among the clean energy sources that are currently known, there are wind, solar, and ocean waves. Solar energy is the source of all energy on the earth. Its output is amazing, but it is limited by the existing technology. The current solar energy application is extremely inefficient. It is necessary to lay a large area of solar panels to replace a small part of the traditional power generation. Countries with insufficient sunshine do not apply. Wave power generation is good, but the sea's arduous movements cannot be predicted. It is impossible to continue to produce effective energy; and the waves are destructive and easily damage the power unit; in addition, the waves are not applicable to landlocked countries. This is not a good alternative. Therefore, in the alternative of clean energy, wind power generation is a fairly mature technology and worth promoting. The history of wind power generation is quite long. As early as a few centuries ago, Europe used windmills in wheat flour mills in flour mills, or in low-lying areas. Wind sources existed throughout the globe, and countries can see them. The terrain and climate are different in configuration. Therefore, there are quite a lot of areas where wind power generation is currently used. Although it cannot replace thermal power generation, it still has certain value. To fully apply wind power for power generation, a good windmill structure is a must-have product. However, in the current wind turbine technology, its performance is rather low, resulting in unnecessary losses. Anyone who has learned basic mechanics knows that in order to obtain the maximum wind energy, it is necessary to increase the area of the wind blade to obtain sufficient air volume, but the large wind turbines that are currently common...the wind-bearing surface area of the blades only accounts for The small area, the blades are designed to be long and slender, the windy area is so small, and its efficiency is naturally not high. Only the designers of existing wind turbines do not know how to invest in it. The authors have studied the following reasons: A. The existing wind turbine designers are mostly high-level intellectuals, so when designing the blades, The high-tech aircraft wing mode is adopted, but since the aircraft must take off at a speed of more than 2 kilometers per hour, the wind speed of the wind is extremely high, which is designed for the high-speed power mode. However, in the case of windmills, because the wind speed in the natural world is mostly low, the speed of the large wind turbine above kW (kw) is about n~22 rpm, but the wind turbine is changed by the aircraft 6 M336997 wing mode design. The blade is a product that runs under high speed. In other words, the use of such aircraft wing pattern blades does not play a role in large wind turbines above 1 kW. In fact, the wing pattern of this aircraft wing mode is only used on high-speed small wind turbines with two-piece blades, and is not suitable for large-scale wind turbines above kW. • B. Actually view the existing loo kilowatts or more wind turbines running, the blades are - the flat plate is windward and slightly off 70 degrees, that is, the wind angle of the electric fan is used, so the theoretical value of the flying wing is 17 degrees. Too far, so such blades do not have high value. The wind turbine's wind blade should have a maximum rotational force of 35 to 45 degrees. The above-mentioned 7-degree angle design is the most powerful force, but the rotating force is dispersed, so the efficiency is extremely poor. c. The design of the existing wind turbine's blades is also considered to be strong winds and momentary gusts. Because the wind blades are damaged by strong winds and instantaneous gusts, they cannot be started when the wind is so small, so there is no power generation during the breeze. Breeze season aging rate report. _· D· Existing wind turbines have a strong and fast fan speed when the wind is 25 meters/second or more. Only when the generator speed is too fast, the generator cannot generate electricity and wastes a good power generation opportunity. E·Hang up point, because the generator can not generate electricity when the speed is too fast, and the wind blade may be damaged when the strong wind is more than 25 meters/second. Therefore, in the management of large wind turbines above 1 kW, it is easy to take the wind. The generator is designed to lock up without generating electricity, but instead wastes high-efficiency generators. 7 M336997 F. The existing wind turbine has a lack of management characteristics. If it can effectively manage the windward angle of the wind blade, it can obtain appropriate wind power under the breeze and absorb a large amount of energy under strong wind to increase the range of wind power. By designing the management concept of “breathing and strong winds”, you can greatly improve efficiency. To this end, the power generation efficiency of the conventional wind turbine is shown in Figure 7. The wind power can be started at about 3 meters per second, and the maximum power generation is achieved at 12 meters/second, and when it exceeds 13 meters/second. That is, the amount of power generation is degraded, and when it exceeds the meter/second, there is no power generation, and the output power of the conventional wind turbine is quite unstable, and its application efficiency is rather low. It can be seen that 'the above-mentioned technology still has a need to be improved. This (4) is based on the above-mentioned shortcomings, and is innovating to 'finally develop and complete this wind power generation device. This device is 50 watts (W)~3, 000, 〇〇〇 Tile (w) size wind turbines are suitable. [New content] The main purpose of this creation is to provide a wind power generation device that automatically adjusts the windward angle of the leaf surface. The applied wind speed field is wide, and can be used in a breeze, strong wind, and gusty environment where conventional wind turbines cannot be started. Work to improve the efficiency of their use. Another object of the present invention is to provide a wind power generation device that automatically adjusts the windward angle of the foliage, which has extremely high power generation efficiency, and can obtain appropriate wind energy in all seasons of the year, and can be efficiently converted into electric energy to improve the use efficiency. The wind power generating device capable of automatically adjusting the windward angle of the blade surface is provided on the wind blade composition of the windmill, and mainly includes a wind receiving plate, a pushing block, a returning unit, and a plurality of rotations. control unit. The wind deflector 8 M336997 is mounted on the rotating axis of the blade to greet the wind surface and receive the wind to generate the thrust force. The push block device is moved backward on the wind receiving plate via the wind receiving plate, and the rack has the same number of racks as the number of blades, and the rack is used for controlling the rotation control. The single 70卩 connection drives the blade to rotate. . The positioning seat is used to limit the moving direction and the distance of the pushing block, and the returning unit is placed between the pushing block and the returning unit, when the wind force of the wind plate is reduced, by the reply unit Push the push block forward to change the angle of the wind_leaf. In addition, the number of the rotation control unit is the same as the number of blades, and each rotation control unit is controlled by the opposite rack, and the rotation angle of the blade is controlled directly or via other guide units via the guide unit, and the reverse operation is also performed by The wind blade is subjected to the force of the momentary gust or strong wind, and the rotation force is transmitted back to the rotation control unit via the rack to the push block 'Using the recovery unit to automatically adjust the force' to protect the blade and the power generation facility. [Embodiment] Please refer to FIG. 1 to FIG. 4, the present invention provides a wind power generation device, which includes a windmill, and the windmill i is designed with a plurality of blades n, as in the present embodiment, four blades are used. U, the wind blade is connected to a generator for power generation via a transmission structure (not shown) (not shown). • The feature of the present invention is that a control mechanism is designed in the plurality of blades 14 for controlling the windward angle of the blade by the strength of the wind, so that the blade u of the windmill 1 is always maintained at the best of the windward surface. The angle, in the wind and strong wind, can play the design of wind power efficiency. The creation is disposed on the rotation axis of the blade 11 and is separated from the blade by a sliding sleeve and a bearing (not shown) so that the rotation of the blade n does not affect the present.

The author I mainly includes a wind deflecting plate 2, a pushing block 3, a fixed seat 4, a returning unit 5 u > a and a hard number rotation control unit 6. The wind receiving plate 2 is mounted on the rotational axis of the blade 11 to greet the wind surface, and receives the wind to generate a push force. The push block 3 is mounted on the windshield 2, and is placed on the wind receiving plate 2, and is moved backward by the wind receiving plate 2. The push block 3 is provided with a plurality of arc-shaped limiting grooves 3, and the rotating shaft of the wind blade η The center is provided with a positioning, a waste bead 111 and a spring Π 2, so that when the push block 3 is pushed by an appropriate force, the ball 111 can be pushed away from the limit groove 3 1, and when the pushing force is insufficient, the ball (1) It is also received by the elastic force 112 in the top limit slot 31; the design of the limit slot 31 is wrong. The creator can set the appropriate distance on the push block 3 according to the relationship between the moving distance of the push block 3 and the angle of rotation of the blade γ. The limiting slot 3b2-limit slot 31 controls an angle of the blade u, and the positioning ball (1) and the bomb=112 limit the wind range of each blade 11 angle, so that the blade U can be operated in a guaranteed state; The push block 3 is provided with the same number of winds (four) = 12, and the rack 32 is used to control the rotation control unit - to connect the driving blades 1 to rotate. The positioning seat 4 is used to limit the moving direction and distance of the pushing block 3, and a positioning block 33' is disposed at the end of the '·= push ^ relative to the guiding hole 4 in the positioning seat 4 A rim 42 is provided to limit the position 嫂 33 to the guide hole 41 (10), and the unit 5 is not capable of being between the push block 3 and the locator 4, =^2. The means for recovering the recovery capability is when the wind receiving plate 2 has a wind = yellow or has an automatic element ~_ shift to change the angle at which the blade i suppresses 罝_β. In addition, the number of the rotation control early turns 6 is the same as the number of the blades U, and the parent rotation control unit 6 is controlled by the M336997 to the opposite rack 32, the rotation control unit 6 having a gear... the teeth *Lir, 32 control, The gear 61 is transmitted to the gear shaft 62 via the gear shaft 62. The gear shaft 63 is driven by the wheel set 63 to the vane shaft seat 64 to guide the rotation angle of the control vane. In the present embodiment, the gear shaft 62 and the gear 61 and the gear set 63 are both The same step of turning 'the wheeled gear set 63 controls the angle of rotation of the blade. In addition, when the wind blade is subjected to a powerful momentary gust, it will automatically reduce the adjustment of the windward surface to protect the wind from damage. The wind blade will transmit the force back to the push block 3 and the recovery unit 5, when the strong wind or moment After the gust of wind, the original windward angle was restored.

As shown in Fig. 5A, when the wind is weak, the blade U can be rotated to the angle of the blade shown by the blade section U to obtain the maximum area. Wind, too large angles will only produce push-back power, without the effect of actually increasing the power. As shown in Fig. 5b, when the wind becomes gradually larger, the angle of rotation of the blade U can be adjusted to a 3 degree angle, which slightly reduces the windward area. As shown in (4), when the wind reaches the maximum, the wind angle ► degree can be adjusted to the twist angle, so that it can maintain a 'stable operation at a wind speed of 25 meters/second. The angle is the design angle of the wing of the aircraft. At this time, the blade is '/乍, and as shown in Figure 5D'. When the wind is too strong, the angle of rotation of the blade U can be adjusted to. The angle is so that it is completely free of wind. The operation angle is set to four, which is controlled by four arc-shaped limit slots provided on the push block 3, and the positions of the limit slots 31 are calculated in advance, which is a gear pitch circumference: The calculation of the example is such that each angle can be loaded with a certain range of wind speed changes, avoiding excessive vibration of the blade 11 and causing damage.
