於上下端部形成朝縱主軸側傾斜之傾斜部，葉片的弦吾 設定為相當於葉片的旋轉半徑40%〜55%之範圍内。 (2) 如前述⑴記載之縱軸風車，其中前述葉片之傾斜部相對 於垂直以30度〜45度範圍傾斜，葉片前端部形成橢圓形。 (3) 如前述（1)或（2)記載之縱軸風車，其中於前述縱主轴以 10 多段狀配置葉片，該葉片由上朝下地朝1方向以等角度轉 位，以平面視之，葉片繞著縱主軸以等角度配設。 (4) 如前述（1)記載之縱軸風車，其中前述葉片以同一水平複 數配設時，由縱主軸至葉片的距離有遠近上的差異。 (5) 如前述（1)記載之縱軸風車，其中前述縱主軸被構造成可 15 於用以構成風車之支持框體中，於水平方向增設複數根。 發明之效果 依本發明，具有以下效果。 (1) 如申請專利範圍第1項之發明之縱軸風車，由於於葉片 的上下端部形成傾斜部，故旋轉時受風損失小，可提高 2〇 旋轉效率。又，由於葉片的弦長設定為相當於旋轉半徑 之40%〜55%的大小，故即使葉片的長度不長，受風面積 了吏大，葉片的數量可變少，旋轉效率變大。 (2) 如申請專利範圍第2項之發明之縱軸風車，由於葉片的 傾斜部傾斜於30度至45度之範圍内，故接觸到傾斜部的 200523470 風會於傾斜部的内側提古 推，因此可提高旋轉力。 風壓，將葉片上下端部朝外 ⑶如申請專利職第3項之發明之縱減車，由於於縱主

除了靠近軸承的地方皆被覆有補強體(5a)^補強體(5a)可 使用例如FRP成形體、鋁型材之單體或其組合等。 -邊補強體(5a)如第1圖所示，藉著由外面連固定體⑻一 同包覆，可提高支持臂（9a)〜(9d)的固定部等之耐候性。 15 此時，可將補強體(5a)之成形體與成形體的連接邻以 FRP樹脂填充後，硬化成形，相結合。 口 於縱主軸(5)上下固定有複數個固定體⑻。固定體⑻

2本發明之葉片（1〇)中，弦長(前後寬度)顯著地變大。 於此葉片（10)中，藉著於葉片（1〇)的上下端部形成傾斜部 15陶’與單純的絲垂直葉片不同，即使弦長變大，經確 認亦可得到理想的旋轉數值。 第3圖係葉片（10)之平面（實線）與正面（假想線）之組合 概略圖。 茶片（10)由於其外側面形成沿著葉片⑽之旋轉軌跡 20 (=圓曲面’故縱轴風車⑴旋轉時，葉片⑽之外側面會 由則至後地沿著旋轉軌跡⑺之圓曲面，因此，沒有由旋轉 執跡(T)路出的部份，旋轉時於葉片（1〇)之離心部因風所造 成之阻力損失很小。 又，於葉片（10)的内側面由於形成膨出部（1〇b)，故旋 200523470 轉時葉片（ίο)的内側面後部會位於膨出部（10b)之旋轉軌跡 (Ta)的外側而旋轉，因此沿著葉片（1〇)的内側面朝後部流動 的風會由膨出部（1 〇b)之旋轉執跡(Ta)朝外側流動。 藉此，於第3圖中，於葉片（1〇)的正面迎風時，迎風會 5 將葉片（10)之内側面後部朝外側推。 於葉片（10)之内側面由於形成膨出部（10b)，故由正面 看，沿著葉片（10)内側面流動的風速會比沿著外側面流動的 風速快，流速較快的那一側由於空氣會變稀薄而成負壓·， 故葉片（10)會被由外側朝前内側推，產生浮力（旋轉推力）， 10 而產生自走旋轉力。 於第3圖中，由旋轉之葉片（10)之左前方碰觸至内側面 之朝葉片（10)上下方向流動的風會接觸到葉片（1〇)之上下 的傾斜部（10a)。傾斜部（i〇a)之前端（P)之旋轉軌跡(Tb)由於 位於較膨出部（10b)的旋轉執跡(Ta)内側，故由膨出部（1〇b) 15朝後方通過的風流不會朝上下方向擴散，會被抑制於上下 之傾斜部（10a)，而於氣壓變高的狀態下朝後方高速通過， 因此會將葉片（10)的内側面後部朝外側推，而成為旋轉力。 又，於第3圖中，碰到傾斜部（i〇a)左側面之a箭頭的風 一接觸到傾斜部（10a)就會朝（a)箭頭方向反撥。以第3圖之 20平面觀之，B箭頭的風會朝（b)箭頭方向反撥。此反撥的風 亦會成為反作用力而加強葉片的旋轉力。 於第3圖中，葉片（1〇)的弦長設定為相當於葉片的旋轉 半徑的50%的長度。但是，葉片（10)的外側面由於設定為沿 著旋轉軌跡（T)之圓曲面，故即使於内側面形成膨出部 200523470 (10b)由㈣時之葉片（1G)之正面看之板厚(助寬度)亦為 相當於旋轉半徑之約7%薄。即，板厚愈薄，愈不會造成旋 轉阻力。 如上構造之縱軸風車G)，即使葉片（10)的長度為例如 5 1m短，藉著於例如7m的縱主軸(5)上下配置4片葉片，全體 亦可成為4片葉片之縱軸風車，具有大的受風面積，旋轉時 可得到強的軸力矩。 上下各葉片（10)，由於為1片葉片，故不會有於縱主軸 (5)之同水平之相反側之風阻，旋轉效率高。然後，即使碰 10到瞬間改變風向的風，由於上下各葉片（10)的方向分別為轉 位90度，故藉著連續的風力的賦與勢能，可如汽車的4氣筒 引擎般地順暢地旋轉，得到強的軸力矩。 於1根的縱主軸（5)上配置多段的1片葉片（10)，且由上 在下依次地使葉片（1〇)的平面相位以預定角度轉位，於全體 15平面以等角度配置葉片（10)時，縱主軸(5)的旋轉平衡性佳。 於1根縱主軸(5)配置多段葉片時，經確認能量係數並不 是為段數的倍數，而是遠超過。即，那是因為例如4段葉片 雖然會產生1段葉片的浮力4倍的浮力，但由於施加於葉片 (10)的阻力負荷會遞減為段數分之一，故旋轉效率會變高， 20葉片（1〇)之旋轉周速變快，能量係數亦變高。 於此實施例1中，雖然葉片GO)是配設為4段，但例如於 將3根縱主軸(5)相連接之狀態下，配設12段葉片（10)亦可。 又，將縱主軸（5)縮短，可配設3段、6段等葉片（10)。 此時，上下段位置之葉片（1〇)的長度可長短不同。 12 200523470 第4圖係顯示本發明之實施例2之縱軸風車要部正視 圖，第5圖係其要部平面圖。與前例相同部位給予相同標 號，並省略其說明。於第4圖、第5圖中之支持框體(4)，省 略其中間之固定臂及斜撐等圖示。 5 於第4圖中，縱主軸(5)以複數個中間軸承(66)支持軸(5) 的縱中間部。各中間軸承(66)藉著架設於支柱(2)之間的固 定臂（3)支持固定。 藉此’縱主軸(5)全體不易彎曲，金屬的縱主軸〇可於 能耐剪斷荷重之範圍内儘可能的細、輕量。 10 於第4圖中，上下各段的葉片（10)分別由2片挾著縱主軸 (5)相對的葉片（1〇)所構成。葉片（1〇)的弦長（前後寬度)例如

Description of the invention: [Technical chair field to which the invention belongs] TECHNICAL FIELD The present invention relates to a vertical-axis windmill, and in particular, to a support frame that is configured as a wind shield and forms a large number of shaft arrangement portions. Multiple blades are arranged in multiple sections on the longitudinal axis of each axis configuration to increase the wind receiving rate. The wind receiving area and rotation efficiency per unit installation area are large, and the installation cost is low. It can become the total power generation per unit area. The windmill of Dazhi Wind Turbine is powered by windmills. 10 Technical background In the past, windmills for wind turbines, such as buoyant 蜇 longitudinal axis windmills, were equipped with a number of straight blades around the longitudinal axis. When the blades on one side of the longitudinal axis were rotated against the wind, the blades on the other side would be affected. The turbulent flow reduces the rotation force, so the shaft torque becomes weak, and the practicability is not good. Although the vertical axis windmill can rotate at high speed even in weak wind, when the number of blades is small, the wind receiving area is small, and when the number of blades is large, turbulence is liable to occur under high speed wind. [Disclosure of the Invention] Disclosure of the Invention 20 Problems to be Solved by the Invention The object of the present invention is to provide a windmill with a large increase in force by π per unit installation area and wind area, and can be half-sided, small cracks, light weight, and greatly increase the installation cost. The reduction applies to the vertical axis windmill of the wind turbine. The method to solve the problem is to expand the chord length of the longitudinal blades, and to arrange multiple sections on the blade root long longitudinal main shafts that form inclined portions at the upper and lower ends of the blades. The specific content of this invention is as follows. (1) A vertical-axis windmill is a device in which longitudinal blades with a left side facing the vertical axis facing the longitudinal axis are arranged at a predetermined interval around the longitudinal axis, and the blades 5 are formed at the upper and lower ends to be inclined toward the longitudinal axis. In the inclined part, the chord of the blade is set within a range corresponding to 40% to 55% of the rotation radius of the blade. (2) The vertical-axis windmill described in (2) above, wherein the inclined portion of the blade is inclined in a range of 30 ° to 45 ° with respect to the vertical, and the front end portion of the blade is formed into an oval shape. (3) The vertical axis windmill as described in (1) or (2) above, in which blades are arranged in more than 10 segments on the longitudinal axis, and the blades are indexed at an equal angle from the top to the bottom, viewed from a plane, The blades are arranged at equal angles around the longitudinal main axis. (4) The vertical axis windmill described in (1) above, in which the blades are arranged at the same level and plurally, the distance from the longitudinal axis to the blades differs far and near. (5) The vertical axis windmill described in (1) above, wherein the vertical axis is configured so that a plurality of windmills can be added in a horizontal direction in a supporting frame for constituting the windmill. Effects of the Invention According to the present invention, the following effects are obtained. (1) If the vertical axis windmill of the invention in item 1 of the patent application has an inclined portion formed at the upper and lower ends of the blade, the wind loss during rotation is small, and the rotation efficiency can be improved by 20%. In addition, since the chord length of the blade is set to a size corresponding to 40% to 55% of the rotation radius, even if the blade length is not long, the wind receiving area is large, the number of blades can be reduced, and the rotation efficiency is increased. (2) If the wind turbine on the longitudinal axis of the invention claimed in item 2 of the patent application, since the inclined part of the blade is inclined within the range of 30 to 45 degrees, the 200523470 wind that touches the inclined part will be pushed inside the inclined part. , Which can increase the rotational force. Wind pressure, the upper and lower ends of the blades are facing outwards. (3) For example, the longitudinal reduction vehicle of the invention of claim 3 of the patent application, because the blades are arranged in multiple stages on the longitudinal axis, and the phase of the blades changes from top to bottom by 5 degrees. It can effectively receive wind from the surrounding area. Another example is the wind turbine on the vertical axis of the invention claimed in item 4 of the patent application. When a plurality of blades are arranged horizontally at the same level, the distance from the longitudinal axis to the blades is different. It will rotate on the same rotation track, without the influence of turbulence, which can improve the rotation efficiency. 10 (3) If the wind turbine of the invention of item 5 of the patent scope is requested, since a plurality of longitudinal spindles can be arranged in the horizontal direction, a plurality of blades can be arranged on a windmill. Embodiment 3 The best embodiment of the invention is arranged on the longitudinal main vehicle arranged on the shaft arrangement portion of the support frame, and is arranged on the upper and lower ends of the upper and lower ends in a plurality of vertical segments and at an equal angle.

The fixed body ⑻ can be used as a flywheel to maintain wind inertia.% The above fixed body ⑻ is a group of up and down, and 4 sections are arranged at fixed intervals in the j-th order. The fixed body (8) is respectively provided with a support f (9) which is parallel to the upper and lower groups, and the base end portion of the support arm 被 is screwed to the fixed body 200523470 (8). 9) The upper and lower intervals are determined in advance according to the length of the blade (ίο). When three support arms (9) are used up and down, the fixed body (8) can also be used in groups of three. 5 4 Each support arm (9 ) The direction of the front part is from the top to the ground, and each group is different. As shown in Figure 2, the uppermost support arm 9a) toward the front. The support arm (9b) of the first slave is set in a direction of rotation (arrow eight). The support arm of the third slave (9c) is set in a direction of rotation The second support arm (9d) is arranged to be rotated 90 degrees in the direction of rotation. This 10 rotation direction can be left or right. Thus, from the top support arm (9a) to In the lowermost support arm (9d), the 90-degree inversion segment totals an inversion angle of 36 °. As shown in Figure 2, each support # (9a) to ⑽ is equal to 90 ° in the plane phase. Angular arrangement. As shown in Fig. 1, the front end 15 of each support arm (9a) to (9d) in the upper and lower sets is vertically fixed respectively-a long blade ⑽, the left γ face of the front of the blade ⑽ (Inside surface during rotation) Faces the longitudinal axis ⑸. The method of fixing the support arm ㈣ to ⑽) and the Chinese flakes (10) can be selected from the screw lock, then FRp, etc. according to the size and weight of the blade ⑽. The support arm ⑼ is made to have the rigidity that can support the blade ⑽ and will not form a shape of wind resistance. The support arms (9a) to (9d) in 11 are formed of FRP plates, for example. The size of the blade is, for example, 100 cm to 100 m in length and 4 cm to 6 cm in thickness. The chord length is changed according to the rotation radius and the number of blades. The chord length of the blade can be 5 to 50% to 65% of the radius. The top and bottom end of the Chinese film (10) is inclined toward the left side to form an inclination of 200523470 (1⑽). The inclined part is inclined at an angle—above 45 degrees, a turbulent flow of wind. If the angle is too small, the wind The reading rate will decrease, and the preferred angle is 30 degrees to 45 degrees. In addition, since the length of the inclined portion ⑽) becomes a hindrance, it is preferable that the length of the blade is less than or equal to the length of the blade. Due to the viscosity of the fluid, the air will hit the side of the blade (1) and rotate. As a result, the “flow into the sepals” will be directed towards the upward and downward directions of the trajectory of the tea leaves CL. The slanting surface 茱 a) is formed on the upper and lower ends of the blade ⑽ side surface ⑺ side surface). The air flowing in the up and down direction will be blocked by the inclined part ⑽), and the air pressure will be increased, pushing the second leaf (10) in the direction of% rotation. Therefore, the rotation efficiency of the blade ⑽ forming the inclined part (pool), Compared with the case where the inclined portion (10a) is not formed, it can be 10% to 40% as follows. 2 In the blade (10) of the present invention, the chord length (front-back width) becomes significantly larger. In this blade (10), By forming the inclined portion 15T 'at the upper and lower ends of the blade (10), unlike simple silk vertical blades, even if the chord length becomes larger, it is confirmed that an ideal rotation value can be obtained. Fig. 3 Blade (10 ) Is a schematic diagram of the combination of the plane (solid line) and the front side (imaginary line). Since the tea leaf (10) forms a rotation track 20 (= circular curved surface) along the blade ⑽ on its outer side, when the vertical axis windmill ⑴ rotates, the blade The outer side of ⑽ will follow the circular surface of the trajectory 由 from back to back, so The portion exited by the rotation track (T) has a small resistance loss due to wind in the centrifugal portion of the blade (10) during rotation. In addition, an bulging portion is formed on the inner surface of the blade (10) ( 1〇b), so when turning 200523470, the back of the inner side of the blade (ίο) will rotate on the outside of the trajectory (Ta) of the bulge (10b), so it will follow the inner side of the blade (10) to the rear The flowing wind will flow outward from the rotation track (Ta) of the bulging part (10b). As a result, in Figure 3, when the front of the blade (10) is facing the wind, the windward 5 will move the blade ( 10) The rear part of the inner side surface is pushed outward. Since the bulging part (10b) is formed on the inner side surface of the blade (10), the wind speed flowing along the inner side surface of the blade (10) will be faster than that along the outer side surface when viewed from the front. The speed of the wind is fast, and the side with the faster velocity will become thinner due to the thin air. Therefore, the blade (10) will be pushed from the outside to the front inside to generate buoyancy (rotating thrust), and 10 will generate self-propelled rotating force. In Figure 3, the blade (10) flows from the front left of the rotating blade (10) to the inner side and flows up and down. The wind will contact the inclined portion (10a) above and below the blade (10). The rotation track (Tb) of the front end (P) of the inclined portion (ioa) is due to the rotation track located at the more bulging portion (10b) (Ta) inside, so the air flow passing from the bulging portion (10b) 15 to the rear will not spread upwards and downwards, and will be suppressed to the upper and lower inclined portions (10a), but to the rear when the air pressure becomes higher. Passing at high speed, the rear part of the inner side of the blade (10) is pushed outward to become a rotational force. In FIG. 3, the wind that hits the arrow a on the left side of the inclined part (ioa) is in contact with the wind. The inclined portion (10a) will be reversed in the direction of (a) arrow. Looking at the plane of 20 in Figure 3, the wind of arrow B will be reversed in the direction of (b) arrow. This counter wind will also become a reaction force and strengthen the rotating force of the blade. In Fig. 3, the chord length of the blade (10) is set to a length corresponding to 50% of the rotation radius of the blade. However, since the outer surface of the blade (10) is set to have a circular curved surface along the rotation trajectory (T), even if a bulge is formed on the inner surface 200523470 (10b), the thickness of the blade when viewed from the front of the blade (1G) (Assistance width) is also about 7% thinner than the radius of rotation. That is, the thinner the thickness of the plate, the less resistance to rotation is caused. The vertical axis windmill G) structured as above, even if the length of the blade (10) is, for example, 5 1m short, by arranging 4 blades up and down on a vertical main axis (5) of, for example, 7 as a whole, the whole can be a 4-axis vertical axis windmill. With a large wind receiving area, a strong shaft moment can be obtained when rotating. Since the upper and lower blades (10) are one blade, there is no wind resistance on the opposite side of the same level of the longitudinal axis (5), and the rotation efficiency is high. Then, even if the wind changes direction from moment to moment, since the directions of the upper and lower blades (10) are respectively indexed by 90 degrees, the potential energy can be applied smoothly by the continuous wind force, like a 4-cylinder engine of a car. Rotate to get strong shaft torque. A plurality of segments of a single blade (10) are arranged on a single longitudinal axis (5), and the plane phase of the blade (10) is transposed at a predetermined angle in order from top to bottom, and the blades are arranged at an equal angle in the entire 15 planes At (10), the rotation balance of the longitudinal axis (5) is good. When a multi-segment blade is arranged on one longitudinal axis (5), it is confirmed that the energy coefficient is not a multiple of the number of segments, but is far exceeded. That is, for example, although a four-stage blade will generate four times the buoyancy of a one-stage blade, the resistance load applied to the blade (10) will be reduced to one-segment, so the rotation efficiency will be higher, 20 The rotating peripheral speed of the blade (10) becomes faster, and the energy coefficient becomes higher. In the first embodiment, although the blades GO) are arranged in four stages, for example, in a state where three longitudinal main shafts (5) are connected, 12 stages of blades (10) may be arranged. In addition, the longitudinal main shaft (5) is shortened, and blades (10) such as 3 and 6 sections can be provided. At this time, the length of the blades (10) at the upper and lower positions can be different in length. 12 200523470 FIG. 4 is a front view of a main part of a longitudinal-axis windmill according to Embodiment 2 of the present invention, and FIG. 5 is a plan view of the main part. The same parts as those in the previous example are given the same reference numerals, and descriptions thereof are omitted. For the supporting frame (4) in Figures 4 and 5, the illustration of the fixed arms and diagonal braces in the middle is omitted. 5 In the fourth figure, the longitudinal main shaft (5) supports the longitudinal middle portion of the shaft (5) with a plurality of intermediate bearings (66). Each intermediate bearing (66) is supported and fixed by a fixed arm (3) erected between the pillars (2). Thereby, the entire longitudinal axis (5) is not easily bent, and the longitudinal axis 〇 of the metal can be as thin and light as possible within a range capable of withstanding the shear load. 10 In the fourth figure, the blades (10) in the upper and lower sections are respectively composed of two blades (10) facing the longitudinal axis (5). The chord length (front-back width) of the blade (10) is, for example, when the radius of rotation of the blade (10) is 1111, the maximum setting should be 40% to 55% of the diameter. The support arms (9 ^ ~ (%) at the same level are set on the same radiation 15. Therefore, when rotating, the rotation balance of the two blades (10) at the same level is good, so the whole windmill (丨) The rotation balance of the support arm (9a) to (9e) in the upper and lower sections is as shown in Figure 5. The uppermost support arm (9a) is arranged in the left-right direction. The support arm in the second section (9b) ) Is arranged at a position rotated 72 degrees in the direction of rotation (arrow A). The support arm of the third slave (9c) is arranged at a position further rotated 72 degrees in the direction of rotation. Μ ^ y. The support arms (9d) (9e) in the fifth paragraph are also respectively arranged at positions further rotated by 72 degrees in the direction of rotation. Figure = The plane phase of the support arms (9a) ~ (9e) seen from above, as shown in 5 °, set to 36 degrees per rotation in the direction of rotation, according to (9a), (9 sentences, (outside), 13 200523470 (9e), (9c), (9a), (9d), (9b), (9e) '(9c) is sequentially indexed and arranged. In the vertical axis windmill (1) of the second embodiment configured as described above, since two blades are arranged into five segments, the number of blades (10) is combined. 10 pieces, the wind receiving area is increased, so a strong axial moment can be obtained. In particular, the wind receiving area of the windmill 5 (1) with the same installation area is 1 section compared with the blade (10), and 5 The segment is more than 5 times, which is overwhelmingly large. The power generation of the windmill is proportional to the area of the blade (10) X the third power of the wind speed, and a large amount of power can be obtained. Figure 6 shows the 2 blades in the vertical axis windmill A plan view of the plane shape. The same parts as the previous example are given the same reference numerals and descriptions are omitted. This vertical axis 10 windmill (1) is made for wind tunnel experiments. The rotation radius of the blade (10) is set to 40 cm and the blade (10 ) Has a length of 80 cm and a chord length of 20 cm. The outside surface of the blade (10) forms a curved surface along the rotation locus (T) of the blade (10). A bulging portion (10b) is formed near the front side. The upper and lower ends of the blade (10) have inclined portions (10a). A wind tunnel experiment is performed on the rotation performance of the 15-blade (10) windmill (1). Test day: July 26, 2004, cloudy weather, air temperature 32 ° C ~ 34. (: Wind tunnel device: owned by Ashikaga University of Technology Device (open type, blow-out port 1.04mx1.04m, variable-speed wind tunnel). Wind speed measurement: Bez (transliteration) type pressure gauge + pitot tube. 20 Test wind speed: 4, 6, 8, 10, 12, 14 (m / s). Number of test wings: past straight blades, chord lengths 13, 16, 20, 23 (cm). BELLSHION blades, chord length 20cm. Test windmill: diameter 80cm, blade height 8 〇cm (manufactured by EFDZEISI). 14 200523470 Torque test: All devices (inverter motor) in the Niushan Laboratory of Ashikaga University of Technology. For the wind tunnel test of straight blades without the inclined portion (10a), the outline of the windmill efficiency (Cp) obtained the following results. 5 String length Ucm. The wind speed is 4m / s and Cp = 0.06. The wind speed is 14m / s and Cp = 0.26. The string length is 16cm. The wind speed is 4m / s and Cp = 0.05. The wind speed is 14m / s and Cp = 0.27. The string length is 20cm. The wind speed is 4m / s and Cp = 0.17. The wind speed is 14m / s and Cp = 0.28. The string length is 23cm. The wind speed is 4 m / s and Cp = 0.10. The wind speed is 14m / s and Cp = 0.29. From the experimental results, it can be seen that although a blade with a 23 cm chord has excellent windmill efficiency (Cp) at high wind speeds (l4m / s), it has poor windmill efficiency at low wind speeds (4m / s). In contrast, blades with a chord length of 20 cm (50% of the radius of rotation), even at low wind speeds (4 m / s), still have a windmill efficiency (Cp) of 1.7, which is significantly better than other blades. 15 Therefore, according to the windmill of the present invention, a wind tunnel experiment result of a blade with a length of 20 cm on a blade (BELLSHION type) with inclined portions (10a) formed at the upper and lower ends is shown below. The string length is 20cm. The wind speed is 4m / s and Cp = 0.25. Wind speed 8m / s, Cp = (X27 〇20 Wind speed 12m / s, Cp = 0.30. Wind speed 14m / s, Cp = (U2.) From the results of the wind tunnel experiment, it can be known that the blade (丨 〇) of the present invention and the general In comparison with straight blades, the blade (10) of the present invention not only has a chord length equivalent to 50% of a radius of rotation of 20 cm in width, but also a straight blade with a chord length of 20 cm at the wind 15 200523470 at a speed of 4 m / s The rotation efficiency is 〇17, and the windmill efficiency (Cp) exceeds 0.25 at a weak wind speed of only 4m / s, which proves that the efficiency of the present invention is very good. That is, the blade (10) of the present invention has the same chord length of the blade Compared with straight blades, under the low speed wind (4m / s) and high speed wind (14m / s), it can show a good efficiency of 5 47% and 14% respectively. This experimental value shows that this vertical axis windmill (1) From low-speed wind to high-speed wind, the difference in rotation efficiency is small and stable. Especially for wind turbines, if the wind above 4m / s in a year is not more than 2000 hours, it is not cost-effective for business. The vertical axis windmill of the present invention which can obtain 10 Cp = 0.25 at a wind speed of 4 claws / § (1) has a lot of regions that do not blow high-speed wind in a year As an excellent characteristic of wind turbines. In this wind tunnel experiment, it was confirmed that the chord length ratio of the blade ⑽ is narrow or wide equivalent to 50% of the radius of rotation, and the windmill efficiency (Cp) is not good, especially in low-speed winds. Efficiency is poor. 15 20

However, depending on the size of the blades, the number of blades, the average wind speed at the installation location, etc., the chord length can be used up to 40% to 60% of the equivalent rotation radius. FIG. 7 is a front view of a main part of a vertical-axis windmill in Embodiment 3. FIG. The same reference numerals are given to the same parts as in the case, and the provinces are omitted. The support phase in Figure 7 is shown in Figure 4 with the towel-shaped arms and cymbals. In this embodiment, the vertical axis windmill ⑴ is used as a supporting frame ⑷ and is directly used in an existing high-voltage transmission tower ′. The electricity generated by the generator (not shown in the abutment (7)) is used to collect electricity in the current collector (11), transform it to 16 200523470 (12), and then recover it through the transmission line (L). This can reduce equipment investment costs and make it easier to recover electricity for power generation in remote areas. As shown in the figure, the rotation radius of the blade (10) can be changed in the upper and lower sections. Fig. 8 shows the front part of the main part of the longitudinal-axis windmill according to the fourth embodiment of the present invention; In the supporting frame (4) in FIG. 8, illustrations of the fixed arm and diagonal brace in the middle are omitted. In addition, a current collector, a transformer, an automatic controller, a rotation speed sensor, a brake device, and the like are omitted. In this example, a plurality of 10 shaft arrangement portions (4a) are formed in a horizontal direction in one support frame (4), and a vertical main shaft (5) is provided in each shaft arrangement portion (4a). That is, it is characterized in that a plurality of longitudinal spindles (5) are arranged in a supporting frame (4). In Fig. 8, although the shaft arrangement portion (4a) shows 2 areas, 10 areas and 20 areas may be formed continuously in the horizontal direction. Thereby, a plurality of shaft arrangement parts (4a) are formed in one support frame (4), and 15 longitudinal shafts (5) are arranged in each shaft arrangement part (4a), respectively. Even if multiple blades (10) are arranged on each longitudinal axis (3), the adjacent blades (10) are oriented in different directions, so the flow of the wind is good. When rotating, the adjacent blades (10) ) Airflow interference will be reduced. The vertical-axis windmill (1) of the fourth embodiment constructed as described above uses one support frame (4) 20 as a whole to form one vertical-axis windmill (1). At the same time, it became a wind turbine. As a result, at each longitudinal axis (5), each generator (not shown) in the abutment (7) is rotated to generate electricity, and when the electricity is collected, the entire supporting frame (4) can become a large-capacity power generator. Wind turbine. The blade (10) in this embodiment 4 can be configured as two blades shown in FIG. Of course, the longitudinal main shaft (5) can also be supported by an intermediate bearing (66) as shown in FIG. In addition, when the shaft arrangement portion (4a) is plural in succession in front, back, left, and right, the number of arrangement stages of the adjacent blades (10) may be, for example, 5 stages, 4 stages, 3 stages, and 5 stages different. 5 This applies, for example, when the terrain is set with bumps. Fig. 9 is a plan view showing a main part of a longitudinal axis windmill according to Embodiment 5 of the present invention. The same reference numerals are given to the same parts as in the previous example, and descriptions thereof are omitted. In the support frame (4) in the figure, the illustration of the fixed arm and diagonal brace in the middle is omitted. As shown in the figure, the vertical axis windmill (1) of the fifth embodiment is shown in the figure, and the 10 plane shape of the supporting frame (4) is structured into a slightly Y-shape. The shaft arrangement section (4a) has 12 zones, but it is also possible to continuously configure 10 zones, 50 zones, etc. in one direction. Depending on the terrain, many shaft arrangement parts (4a) may be arranged in one direction and fewer shaft arrangement parts (4a) may be arranged in the other direction. In the continuous direction, the plane phase of the shaft arrangement portion (4a) can be indexed back and forth. 15 FIG. 10 is a plan view showing a main part of a vertical axis windmill according to Embodiment 6 of the present invention. The same reference numerals are given to the same parts as in the previous example, and descriptions thereof are omitted. In the supporting frame (4) in FIG. 10, illustrations of the fixed arm and diagonal brace in the middle are omitted. In this embodiment 6, as shown in the figure, the length of the support arm (9) of the blade (10) is different from the left to the right, and the length is set to a remote blade (10A) and a proximal blade (10B). The maximum difference between the short support arm (9B) and the long support arm (9A) should be within the range of 1: 2. The remote blades (10A) and the proximal blades (10B) are arranged in the upper and lower sections in Fig. 10, so the support arms (9A) (9B) are arranged in series on the plane. For example, the length of the support arm (9A) (9B) is shifted every 90 degrees when there are four segments. 18 200523470 In the figure, the blades (10A) (10B) are set to be shorter in the length of the remote blade (108), and the length of the closer blade (10B) is longer. The short support arms (9B) (9A) are about ι · 2 in length, the chord length of the remote blade (10A) is 100 cm when the chord length is 50% of the radius of rotation, and the proximal blade (10B) is 50 cm. Let the length of the remote blade (10A) 5 be 100 cm and the length of the proximal blade (10B) be 200 cm, so that the wind receiving area of the two blades (10A) (10B) is the same. The remote blade (10A) and the proximal blade (ι〇Β) are not affected by the same rotation when rotating, so they are not easily affected by the turbulence caused by mutual rotation. Claw ^ As a result, since the i-blades are set in sections to increase the wind receiving area, the rotation efficiency is good. That is, the advantages of the i blade and the advantages of the two blades are combined.

The chord length of the blade (10) can be equivalent to 50% of the radius of rotation, but because it is 3 blades, so it is equivalent to 40% to 45%, which is better than 2 blades. The plane phase of the blade ⑽ is located at 30 or 60 degrees of vertical displacement. In addition, the generator (13) is arranged in the upper and lower sections. It is configured to generate power individually through the rotation force of the longitudinal spindle (5) via the transmission device 10. The arrangement of each generator (13) is not shown. It is an automatic clutch device for the opening and closing device of the automatic loader. On the abutment, a bearing (not shown), a gear shifter, a rotation speed sensor, an automatic control device, an automatic brake device, a rotation assist motor, etc. are provided. 5 Sense of rotation speed The detector is used to detect the rotation speed of the longitudinal spindle (5), and the automatic control device will control the related devices and machines according to the detected value. For example, when the wind is below 4m / s, it will be used as an automatic every certain wind speed stage. The automatic clutch device of the load opening and closing device is driven to open and close. By this, the automatic clutch device in the upper and lower 4 generators (13) can be opened, so that the rotation of the longitudinal spindle = = does not drive to the generator (13) The number of generators is 丨 3, and the vertical windmill (1) can be rotated under a load of low wind speed to generate power at a low wind speed. When starting at a low wind speed, only 丨 sets The generator (13) is connected to the longitudinal axis, σ, and σ, and I1 increases the wind speed, which increases the number of connections of the generator (13) 20 200523470. Therefore, it is possible to configure more than i generating capacitors when there is no wind, By automatic control The generator (13) is installed. The rotation auxiliary motor is used to start the windmill ^ 'and drive the brake device not shown in the figure. The automatic brake gear is placed ^: When it is in the gorge, it will let its own electric load device In addition to other devices such as machinery, other automatic loader opening and closing devices can be used to open and close switches for loaders such as electromagnetic coils.
