More specifically, the system refers to a wind blade with a pressure relief hole. η [Previous technology] According to the emergence of the energy crisis such as oil, the current countries are not trying to develop new alternative energy sources, such as wind energy, solar energy, geothermal energy, tidal energy, etc., among which wind energy has zero The characteristics of pollution and low construction cost are widely favored by various countries. Please refer to the first figure, which is a kind of wind turbine that is known as a tower crane. The tower is connected with the top of the tower. a generator body 2, the generator body 2 is connected to a set of blades 3 at the front end thereof, whereby the wind turbine can drive the blade 3 to rotate around the shaft, and the generator body 2 is driven to generate electricity, thereby converting wind energy into Electrical energy for use. However, although the amount of power generated by the wind turbine is proportional to the wind speed, excessive wind speed will cause the blade 3 to rotate too fast, causing the generator body 2 to over-run and burn, so that the current wind turbine All have automatic braking device. When the wind speed exceeds the predetermined value, it will automatically decelerate or stop running. The effect of the intelligent braking device can not alleviate the wind pressure on the blade 3. The excessive wind speed will still cause The wind turbine suffers from blade breakage and other damages, especially in areas prone to hurricanes such as Taiwan. It often reaches winds above the level, and the wind direction is unpredictable, which will cause serious threats to the wind turbines. The year-old girlfriends run the wind, which caused Taichung Port No. 2 wind power to collapse. Therefore, how to develop a kind of decompression device to automatically start when the wind speed is too high, it is necessary to mix the wind pressure of the wind turbine as a whole. . 3 [New content] This creation provides a kind of wind blade with reduced wind, which is placed on a wind turbine, which contains the ship's surface and the leeward surface at the touch, and the blade is fastened. There are several pressure-reducing holes on the windward side and the leeward side, and an automatic pressure reducing device is arranged in the dust-reducing holes. This kind of creation provides a kind of wind with a hole (9). Under normal conditions, the automatic reduction depends on the lag hole, without affecting the operation efficiency of the material, and when the wind speed is too large 'The self-arming Wei set age, so that (4) directly passes through the vane through the decompression hole to reduce the wind pressure on the blade, avoiding the excessive wind speed causing damage to the blade, and even the collapse of the wind turbine accident. [Embodiment] "After the first and second figures, a perspective view and a partial enlarged cross-sectional view of a preferred embodiment of the present invention, the wind generator 1()() includes a tower 1G, a generator body 20 and a set of blades 30, and the blade 3 is provided with a plurality of automatic pressure reducing devices 40, wherein: the blade 3G includes a windward surface 31 and a leeward surface on the opposite side. The blade 30 is provided with a plurality of pressure reducing holes 33 extending through the windward surface 31 and the leeward surface 32. The pressure reducing holes occupy the area of the windward surface 31 and jump to 2%, in this embodiment. The pressure reducing holes 33 are disposed between the chord line and the trailing edge of the blade 30, and are provided with five decompression holes along the axial direction of the blade 3〇. The automatic decompression device 40 is housed in the decompression hole of the blade 3, and in the embodiment, the automatic decompression device 40 has a socket 41, a valve stem 42 and two elastic M374s. The member 43' is fixed to the inner wall of the reducing hole 33, and both ends of the bearing 41 are axially of the reducing portion 33. The bottom surface of the receiving groove 411 is further stepped into a shaft hole 412 having a smaller diameter, and the bearing 41 is provided with a plurality of perforations around the groove of the receiving groove 1. The valve stem 42 is disposed in the shaft hole 412 of the socket μ, and the two ends of the valve stem 42 are respectively formed with a stopper portion 421 of the same diameter as the diaphragm hole 33. The rod 42 is formed on the inner side of the supporting portion 421 opposite to the inner side of the shoulder portion 422. The elastic members 43 are sleeved on the valve cup 42 and are respectively accommodated. In the sockets 411, the elastic members are affixed to the shoulders 422 of the valve stem 42 and the bottom surface of the socket 411 to provide an elastic force, the valve stem 42' The stoppers 421 are elastically suspended and sealed at both ends of the decompression hole 33. For the purpose of the creation of the structure of the county, the means of operation, and the means of achieving the use of the creation, I believe that you can have a deeper and more specific understanding of this creation, as follows: • ▲ Please also refer to the fourth figure, in the normal state, the automatic decompression device 4 The Μ21 system stops the sealing on the decompression hole without affecting the operating efficiency of the blade continent. When the wind speed exceeds a predetermined value, the valve stem 42 of the automatic decompression device 4 will be directed to the blade The leeward direction of the 30 is moved in the direction of 32, and the decompression hole is opened, so that the airflow directly passes through the vane 30' from the decompression hole 33 to reduce the wind pressure of the blade 3〇, thereby avoiding excessive The wind speed causes the blade 3 to be damaged, and even the wind turbine collapse accident occurs. Of course, when the wind is struck by the leeward side of the blade 3G, the valve stem 42 of the automatic pressure reducing device 40 will face the wind. Move in the direction of face 31 to open the dust reduction hole, 5 to achieve the effect of decompression.
