Therefore, it is impossible to control the change of wind speed in a short time. When the 4 windmills are used in wind turbines, the output voltage will be constant t: moving + ringing wind speed. It is difficult to maintain the rotational speed of the windmill or even the output power within a certain range. In addition, the longitudinal wing of the vertical axis windmill is damaged by strong wind such as a hurricane, or the rotation speed is too high, resulting in the destruction of the entire windmill. 3 201040387 It is made of soft material, and the rear part of the rear wind direction in the direction of the spring wind = long wing _ is deflected. When the speed exceeds a certain value, the rotation of the longitudinal wing - the direction of the longitudinal wing ^ 疋When the wind is deflected, and the next person, the direction of the rotation of the instantaneous wing, will be centrifugally oriented, and the purpose of the present invention is to sway in the axial direction, thereby causing wear and tear. The above is to provide a longitudinal wing of the vertical axis windmill, which moves in the centrifugal direction, = when the wind is winded, 'the rotation speed of the windmill can be controlled by one part of the longitudinal wing and the rotation speed is maintained , ~, , 疋fe circumference. Means for Solving the Problem In order to achieve the above objectives, the specific means of (1)-species length t and 胄明 are as follows. The vertical main car of the windmill is arranged around the vertical axis by the support arm, and the vertical axis is movable. And the rear end portion in the rotation direction of the main body portion is provided with (2) the centrifugal force at the time of turning on the coffee and shaking. (2) In the upper side (1), at the inclined portion of the main oblique portion, and at the upper end portion of the upper portion, the base end portion of the inwardly inclined portion which is in the direction of rotation of the tilting body portion in the main axis direction is formed at the end of the main moxibustion portion With movable wings. (3) In the above (2), the lower end portion of the wing is covered with the movable end portion (4) as in the above (1) to (3) to the wing, and the longitudinal length of the vehicle is reduced by the hinge. The movable wing is disposed between the main body portions and is attached to the main body portion and is movable to the movable wing device. (5) The above-described chain (4) is formed by fitting a bearing of a hinge of a movable wing to a sleeve of a main body portion of a longitudinal wing of a movable wing shaft 7 . 201040387 (6) The longitudinal chain of the thief car described in (5) is hinged by the trailing edge of the main body and the movable wing, and the movable wing is hinged. The elastic sheet of the edge is shaped (7) In the above (6), the movable wing, the rear green and the movable material body have heavy weight, and the weight of the movable wing 2 with the movable wing has a movable force by centrifugal force ( 9) In the vertical axis windmill according to (8), the weight of the free end of the wing moving toward the centrifugal side when the longitudinal wing is rotated beyond the constant rotation speed. (1) In the above item (8) or (9), the moving wing moves before and after. The weight of the movable wing is mounted so that the weight of the movable wing can be made up of a small number of items (11) of uranium (8) to (1). Effect of the Invention According to the present invention, the following effects can be achieved. According to the longitudinal wing of the vertical axis wind turbine described in the above (1), since the movable wing is attached to the rear portion in the rotational direction of the main body portion, when the longitudinal wing exceeds the predetermined rotational speed, the movable blade is rocked by force and force, and The free end is facing away from the direction of the dog. Therefore, the resistance is applied to the movable wing, and the rotation of the longitudinal wing is maintained at a certain rotational speed. When the rotation speed is lowered, the movable wing gradually returns to the original position because the centrifugal force is also lowered. Therefore, even if a high-speed wind is blown, the rotation of the predetermined rotation speed or more can be suppressed, and the rotation speed of the longitudinal wing is maintained at a constant value of 201040387. As a result, the output can be maintained within a certain range during wind power generation. In the longitudinal wing of the vertical axis wind turbine according to the above (7), the lower end portion of the main body portion is formed with an inclined portion that is inclined toward the wire direction, and the inner portion of the inclined portion is attached to the rear portion of the body portion. Therefore, in the case of the Rotary Temple, even if the airflow spreads toward the wing end of the main body portion, it can be suppressed by the inclined portion and completely flow to the rear of the rotation direction. When the longitudinal wing exceeds a certain rotational speed due to the high-speed wind, the free end of the movable movable wing moves toward the centrifugal side, and the airflow which is prevented from being diffused by the inclined portion flows toward the movable wing side, and the movable wing is pushed to the centrifugal side. Since the resistance is applied to the movable wing that protrudes toward the centrifugal side, the rotational speed of the longitudinal wing is reduced as the manufacturing operation, so that it is no longer possible to rotate at a high speed. When the wind speed is reduced, the centrifugal force is also reduced, so the movable wing returns to the original position. In the longitudinal wing of the vertical axis wind turbine described in the above (3), since the upper end portion of the movable wing is covered by the inclined base end portion of the inclined portion, the wind flow to be diffused from the main body portion toward the wing end side during rotation It is restrained by the inclined portion and flows toward the movable wing side, and effectively acts on the movable wing. In the longitudinal wing of the vertical axis wind turbine described in the above (4), since the movable wing is attached to the main body portion via the hinge, the hinge portion can be easily pivoted as a fulcrum, and the return mechanism is provided between the main body portion and the movable wing. Among them, the posture recovery of the movable wing by the return mechanism can be easily performed when the wind speed is lowered. In the longitudinal wing of the vertical # windmill described in the above (5), the bearing of the movable wing is used as a branch, so that the rocking of the swaying wing can be smoothly performed. In the longitudinal wing of the vertical axis wind turbine described in the above (6), since the movable wing is attached to the main body portion via the hinge, the free end portion of the movable wing can be easily shaken. Further, since the hinges are coupled by the elastic sheets, the free ends of the movable blades are easy to shake, and there is no rust, and the weather resistance is excellent. In the longitudinal wing of the vertical axis windmill described in the above (7), the hinge of the movable wing is formed of an elastic plate and has a return mechanism. Therefore, when the centrifugal force is applied to the movable wing, the swing is performed, and when the rotational speed is lowered, It can be naturally returned to its original position by the elasticity of the elastic plate. In the longitudinal wing of the vertical axis windmill described in the above (8), the weight is attached to the free end of the movable wing. Therefore, when the centrifugal force acts as the longitudinal wing rotates, the free end of the movable wing is centrifugally The side protrudes to produce a braking effect. The longitudinal wing of the vertical axis wind turbine described in the above (9) is attached with a weight having a considerable weight so that the free end of the movable wing can be moved to the centrifugal side by centrifugal force when the rotation exceeds a certain rotational speed. Therefore, when a certain number of rotations is exceeded, the wind force or the recovery mechanism can be counteracted, and the weight of the movable wing can be moved in the centrifugal direction by the centrifugal force to generate a braking action. When the wind speed is lowered, the movable wing is returned by the return mechanism. In the home position, the rotational speed of the longitudinal wing can be maintained within a certain range. In the longitudinal wing of the vertical axis wind turbine described in the above (10), the weight of the movable wing can be moved in the front and rear directions of the movable wing. Therefore, in order to adjust the swing of the movable wing by the number of rotations, the position of the weight can be adjusted. In the longitudinal wing of the vertical axis windmill described in the above (11), the weight of the movable wing uses a plurality of small objects. Therefore, even if the longitudinal wing is broken by a typhoon or the like, it does not cause a big blow to other objects. . 201040387 BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a front elevational view showing a first embodiment of a vertical axis windmill according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A movable wing that can be swung by centrifugal force during rotation is attached to the rear portion of the longitudinal direction of the vertical axis windmill. [Embodiment 1] Embodiment 1 of the present invention will be described with reference to the drawings. The casing 3 is fixed to the upper end of the longitudinal main shaft 2 in the windmill 1, and a rotatable rotating body 4 is disposed on the upper side of the casing 3. The rotating body 4 is attached to the longitudinal wing 6 via the support arm 5. The longitudinally long 6-series resin molded body may have any number of sheets of 5 sheets. A power generator (not shown) is disposed in the casing 3, and a magnet (not shown) is disposed in the rotor 4. The rotating body 4 rotates in accordance with the rotation of the longitudinal wing 6, thereby generating power generation by a power generator (not shown). An inclined portion 6B that is inclined toward the longitudinal main shaft 2 is connected to the upper end portion of the vertically long main body portion 6A of the longitudinal wing 6 in the upper end portion. In Fig. 3, the right side is the front part in the direction of rotation, and the left side is the rear part in the direction of rotation. In the longitudinal wing 6, between the upper and lower directions 201040387, the movable portion 7 is attached between the base end portions 6C and 6C of the inclined portion 6Β and 6Β in the rotational direction of the main body portion 6Α. The movable wing 7 is located on the extended surface of the trailing edge of the main body portion 6 of the longitudinal wing 6, and a weight 8 is attached to the rear end of the free end portion. The installation method is other than burying, and the method can be any. The movable wing 7 is formed in a thin plate shape as viewed in plan, and as shown in Fig. 4, a hinge 7 attached to the base end portion thereof is pivotally mounted on the rear edge of the main body portion 6''. The Ο 成 is integrally formed with the movable wing 7 and is close to the front end portion of the contact protrusion formed on the base end portion of the base end portion protruding to the opposite side of the weight 8 with the hinge 7 , as the center, and is in contact with the main body portion. The return mechanism 9 is 6D and is composed of a leaf spring. When the windmill is configured to rotate as described above, and the longitudinal wing 6 is rotated at a high speed higher than a predetermined speed, the movable blade 7 is as shown by a broken line in FIG. 4 by the centrifugal force and force acting on the weight 8. With the hinge 7A as a fulcrum, it is rotated in the centrifugal direction against the return. As a result, the airflow that is struck along the outer side of the longitudinal wing 6 is suppressed by the movable wing 7, and is rotated by the braking action; when the square turn speed is lowered, the centrifugal force acting on the movable wing 7 is also Reducing this 'contact protrusion 7B' is pushed back to the centrifugal direction by the return mechanism 9 to return to the home position on the extension line of the trailing edge of the longitudinal wing 6. The 1st phase of the moving wing 7 7 changes, the degree of rotation also changes, and the force of the moving wing ~ force also changes, so 'reversely shakes, and when the material is weak in the wing and ^ 弋 below, back In situ. 9 There is no need for other rotation control mechanisms, and in the event of strong winds, the 201040387 longitudinal wing 6 can also automatically rotate within the range of rotational speed. As long as the longitudinal wing 6 is rotating, even if strong wind is applied, the airflow can move along the surface of the longitudinal wing 6, so that strong wind does not act on the longitudinal wing 6, and the longitudinal wing 6 can be prevented from being damaged. Therefore, not only the longitudinal wing 6 is rotated in a strong wind, but also rotating at a low speed can effectively function as a wind power generator. When the weight of the weight 8 in the movable wing 7 is increased, the movable wing 7 can be shaken by the heart force even if the rotation speed is slow. On the other hand, when the weight of the weight 8 is reduced, the movable wing 7 does not shake when the money rotation speed cannot reach above. Therefore, by adjusting the weight of the weight 8, the rocking process can be arbitrarily adjusted. Alternatively, the strength of the addition and subtraction recovery mechanism 9 is added instead of the weight of the weight 8, whereby the rocking of the movable wing 7 can be suppressed. [Embodiment 2] Fig. 5 is a cross-sectional plan view showing an essential part of the longitudinal wing of Embodiment 2. The same reference numerals as in the previous example, the same reference numerals, are omitted. The 4 shell-domain 2 + II body is a rubber-based elastic 丨 _ which is a one-piece and elastic base of the movable wing (7), and is a secret 1GA. The elastic piece in the base end of the yarn key is in the rear of the main body 6A of the longitudinal wing 6 in the direction of rotation 6 〇. With the rotation of the longitudinal wing 6, when the centrifugal force acts on the weight 11 at the free end of the rear portion of the movable wing 10, the elastic chain will flex, and the free end of the movable wing H) will oscillate in the centrifugal direction. . As a result, the movable wing 1 突出 protruding outward from the outer side of the longitudinal wing 6 generates a braking action, and the rotational speed of the longitudinal wing 6 is lowered. 10 201040387 When the wind speed is reduced, the elastic hinge 10A acts as a return mechanism, and the free end of the movable wing 10 is returned to the original position by the centrifugal side. The rest is the same as in the first embodiment. [Embodiment 3] Fig. 6 is a side view showing the longitudinal wing 6 of Embodiment 3, and Fig. 7 is a sectional view taken along line VII-VII of Fig. 6. The same portions as those in the previous examples are given the same reference numerals and the description is omitted. In the longitudinal long wing 6 of the third embodiment, the inwardly inclined portion 6B forms a wing end portion which covers the movable wing 12. With this, during the rotation, the wind flow that is to be diffused toward the wing end of the main body portion 6A is suppressed by the inward inclined portion 6B and flows to the rear of the rotation, and flows from the inner side surface of the movable vane 12 to the outside, and can be efficiently generated. Braking effect. The hinge 13 uses a bearing on the side of the movable wing 12, and supports the bearing by a support shaft 13A provided on the main body portion 6A of the longitudinal wing 6, whereby the rocking can be smoothly performed. The weight 14 is such that short lengths are arranged in series or in parallel so that the movable wing 12 does not malfunction when it is broken by a typhoon or the like. Further, the weight 14 can be formed by bolting a bolt or a pin to the outer surface of the movable wing 12. The degree of the rotation with the rotational speed of the movable wing 12 can be adjusted by the position of the weight 14 before and after. [Embodiment 4] Fig. 8 is a cross-sectional view showing the longitudinal wing 6 of Embodiment 4. The same parts as those in the previous example are given the same reference numerals and the description is omitted. The reply mechanism is omitted. 11 201040387 In the fourth embodiment, the main body portion 6A and the movable wing 15 are separated by a portion of the hinge 16 and formed by a film-like elastic plate 17. The elastic layer 17 is coated with an elastic resin in a film-like manner, and the elastic sheet 17 is made of a synthetic resin fiber (not shown) #柯纤维 is a polyester fiber with elasticity and softness, so even after many times: the durability of the tree is also good. , bending, the weight of the whole body. Further, in Fig. 8, the weight 18 is a plurality of bolts and is combined with the movable wing 15. Thereby, the weight outer screw can be adjusted by the number of bolts. As described above, in the present invention, the rotation of the longitudinal wing 6 is attached. The movable wings 7, 10, 12, and 15 of the portion can swing the free end portion in the centrifugal direction in response to the force after the wind speed is changed. Therefore, if the setting of the centrifugal is appropriate, even in the state of being placed in a typhoon The movable wing can be shaken by the centrifugal force generated by the rotation, and the H-rotation generated thereby naturally maintains the rotational speed of the longitudinal wing 6 within a predetermined range. As a result, even if it is rotated under the wind (4), by the centrifugal force, the movable wings 7, 1, 〇, 12, 15 can be used for T-speed, and the rotation speed is maintained at - (four) mode rotation, riding - The output is fixed, so the division will stop the loss associated with 6 when recording strong winds. The present invention is not limited to the above-described embodiments, and the design can be appropriately changed according to the purpose. Lai (4) 9 If it is to produce the effect of returning to the original position 12 201040387, as long as it does not become the resistance of the wind, or the rotation efficiency is reduced, why not. According to the present invention, the movable wing is attached to the rear of the longitudinal wing, and the free end of the movable wing is shaken by the centrifugal force during rotation to generate a braking action, so that it does not exceed a certain rotational speed when placed under strong wind. Therefore, it can be effectively utilized in a wind power generator that must maintain a certain output.
