  The operating state acquisition unit 703 is a power generation output detection unit that detects a power generation output from the power generator 500 of the wind turbine generator 1, and here is an ammeter that detects a power generation current and a voltmeter that detects a power generation voltage. The control unit 3000 specifies a predetermined power generation amount (a power generation current, a power generation voltage, a power generation, etc.) based on the output signals from these, and a management device using the power generation amount data as a result of the specification as operation status data 1000.

  The operating state acquisition unit 704 is an angle sensor (blade angle detection means) that detects a blade angle, which will be described later, of each blade 30 of the wind turbine 3 of the wind turbine generator 1. 33 is a potentiometer. The control unit 3000 identifies the blade angle based on the output signal from the potentiometer 704, and transmits the blade angle data, which is the identification result, to the management apparatus 1000 as operating status data. The blade angle referred to here is an angle formed by the width direction of the wind receiving surface of the blade 30 and the rotation axis direction of the rotating shaft. In the present embodiment, the blade is configured to vary the angle according to the magnitude of the wind force. An angle adjustment mechanism 300 is provided.

  The operating state acquisition unit 705 is a camera (photographing means) that captures a moving image of the appearance of the windmill 3 of the wind turbine generator 1 or the blade 30 of the windmill 3, and is here attached to the column 110 of the wind turbine generator 1 The third blade 30 is photographed. The control unit 3000 acquires captured image data (moving image data in this case), and transmits this to the management apparatus 1000 as operation status data.

  The wind speed state acquisition unit 702 is a wind force detection unit that detects wind force around the windmill 3 of the wind turbine generator 1. Here, a known anemometer that measures the wind speed around the windmill 3 and a wind direction that measures the wind direction around the windmill 3. It is a total. The control unit 3000 specifies a predetermined wind state (wind speed, wind direction, etc.) based on the output signals from these, and transmits the determination result to the management apparatus 1000 as wind state data.

  Further, the control unit 3000 stores the wind power generator in a predetermined storage unit (for example, a ROM) based on a data transmission program 3000a that transmits the data obtained as described above to the management device 1000 and an instruction from the outside. A forced control program 3000b that forcibly stops is stored.

  The wind turbine generator 1 includes a brake device (forced stop unit) 600 that forcibly stops the rotation of the wind turbine 3 based on a forced stop command from the external management device 1000.

On the other hand, as shown in FIG. 4B, the lock mechanism 620 drives the drive unit (motor) 622 to lock the lock member 621 in the lock position (right of FIG. 4B) and the unlock position (FIG. 4). The lock member 621 shifts to the unlock position when the rotary shaft 2 falls below a predetermined rotation speed. In the unlocked position, the lock member 621 is inserted into a through-hole 629 that passes perpendicularly to the axial direction of the rotary shaft 2 and rotates integrally. However, the distal end 621a thereof rotates against the rotation of the rotary shaft 2. Therefore, the positioning member 628 fixed integrally with the nacelle 200 side in a non-interlocking manner is brought into contact with the positioning direction side, so that the rotation is restricted. Thereby, the rotation of the rotating shaft 2 is also restricted.

  As shown in FIG. 1, the management apparatus 1000 includes a main management apparatus 1000A that manages and monitors all wind power generators 1, and a sub that targets a part of all wind power generators 1 as management and monitoring objects.

In FIG. 1, the management / monitoring targets of the management apparatuses 1000A, 1000B, and 1000C are indicated by broken lines.

  As shown in FIGS. 5 and 6, these management apparatuses 1000 (1000A to 1000C) include a keyboard, a mouse, other pointing devices, and the like for a control unit 1001 configured with a CPU, a ROM, a RAM, and the like.

  The storage device 1005 stores various programs executed by the control unit 1001 and various data necessary for executing the programs. Specifically, as shown in FIGS. 5 and 6, the storage device 1005 stores various data (operating state data and wind state) transmitted from each wind power generator 1 that is predetermined as a management target. Data) sequentially received via the communication means 2000, and stored / accumulated in the storage device 1005 based on the data collection program (operating condition receiving means and wind condition receiving means) 1005a and the wind condition data received sequentially, The normal state of the operating state data that specifies the wind power state around the wind turbine 3 of the wind power generation device 1 that is the transmission source and specifies that the wind power generation device 1 is operating normally in the specified wind power state.

  Further, in the storage device 1005, as shown in FIGS. 5 and 6, the power generation amount data included in the operation state data received from the wind power generation device 1 that is predetermined as a management target is used in each wind power generation device 1. Global warming gas reduction amount calculation means that converts the reduction amount of global warming gas (here it is carbon dioxide, but may be other applicable gas) and the cumulative value of the reduction amount Are stored and stored in the storage device 1005 (global warming gas reduction amount storage unit) for each wind power generator 1 (reduction amount global warming gas reduction amount storage means), and the global warming gas is discharged from the accumulated value Emission right value is calculated for each wind power generator 1 (global warming gas emission right value calculation means), and the emission right value is stored in the storage device 1005 (emission right value storage unit) for each wind power generation apparatus 1 Calculation It stores a program 1005d. The output program (output means) 100e includes not only the normal / abnormal result for each wind power generator 1, but also for each wind power generator 1 that is a management target, for all the wind power generators 1, or a plurality of predetermined numbers. The emission right value of the global warming gas of the wind power generation apparatus group including the wind power generation apparatus 1 is also output (emission right value output means).

  The amount of reduction of global warming gas (carbon dioxide in this case) is determined according to the measurement and calculation method of the known global warming gas emission reduction (here CO2 emission reduction) by power generation using renewable energy. calculate. In other words, in the case of wind power generation using wind power, which is renewable energy, the amount of fossil fuel consumed is generally zero, but how much if you think that power generation using wind power was performed instead of power generation using conventional fossil fuel? It is possible to calculate whether the consumption of fossil fuel can be reduced. For this reason, first, the amount of power output by power generation using renewable energy is measured, and the cumulative output power amount in a predetermined period is set as the cumulative power generation amount. Next, by multiplying the accumulated power generation amount obtained by wind power generation by a predetermined coefficient, the amount of fossil fuel necessary for the same amount of power generation is calculated by conventional power generation using fossil fuel. Then, the calculated fossil fuel amount is regarded as an unused amount of fossil fuel that has been necessary in the past, and this unused amount is converted into a carbon dioxide generation amount to reduce carbon dioxide emissions. Amount (reduced carbon dioxide emissions). This conversion can be performed by converting the unused amount of consumed fossil fuel into a theoretical amount of carbon dioxide generated when the fossil fuel is burned. Specifically, the carbon dioxide emission reduction amount is calculated by multiplying the unused amount of consumed fossil fuel by a predetermined coefficient. Of course, it may be adjusted based on not only the theoretical amount of carbon dioxide but also experimental values.

  The emission right value of the global warming gas is calculated as a monetary value by, for example, multiplying the accumulated power generation amount by a predetermined trading rate (for example, about 6 to 7 yen / kWh). You may calculate based on the calculated carbon dioxide emission reduction amount.

  Further, as shown in FIGS. 5 and 6, the storage device 1005 stores received data 1005 f such as received operating state data and wind state data for each wind power generator 1 that is predetermined as a management target. In addition, the normal / abnormal identification result of the wind turbine generator 1 identified based on the received data 1005f and output data 1005g such as the calculated carbon dioxide reduction amount and emission right value are stored. In the present embodiment, received data 1005f is stored with time information described later in association with it.

  However, in the storage device 1005 of the main management device 1000A, as shown in FIG. 5, the force of the windmill 3 is forced against the control unit 3000 of the wind turbine generator 1 identified as abnormal by the abnormality identification program (abnormality identification unit) 1005c. A remote control program (forced stop command means) 1000h that outputs a stop command and causes the brake device 600 to forcibly stop the wind turbine 3 is stored, but the other management devices 1000B and 1000C are as shown in FIG. Is not remembered.

  A data transmission program 3000a executed by the control unit 3000 of each wind turbine generator 1 will be described with reference to FIG.

  When the data transmission program 3000a is executed, the control unit 3000 performs rotation speed data based on the detection signals received from the acquisition units 701 to 705 with the arrival of a predetermined period (for example, 1 second) (S1: Yes). Calculation (generation) of operating state data such as power generation amount data, blade angle data, and photographed image data, and wind state data indicating a wind state (wind speed, wind direction, etc.) in a predetermined cycle (for example, 1 second), and the control unit 3000 Or the external memory 3001 connected to the control unit 3000 (S2). These calculation results are stored in the form of being updated for each type of data. Subsequently, the control unit 3000 reads the latest operating status data and wind power state data (stored latest data) stored therein, and obtains the identification information of the wind turbine generator to which it belongs and the time information indicating the current time. Correspondingly (S3), the transmission / reception unit 800 transmits the data to the management apparatus 1000 that is predetermined as the transmission destination (S4). Thereafter, if there is a termination command for this program (S5: Yes), but if there is no termination command, these (S1 to S4) are repeated. Thereby, from each wind power generator 1, operation state data and wind state data are transmitted sequentially (in real time) to management device 1000 defined as a transmission place.

  When the data collection program 1005a is executed, the control unit 1001 first determines whether or not the operating state data and the wind state data transmitted from the wind turbine generator 1 determined as a management target are received (S11). If the operating status data and the wind power data are received, the source wind turbine generator 1 is identified based on the identification information associated with the data (S12), and the identified wind turbine generator is identified. The operation status data and the wind power status data are stored in the storage device 1005 in association with each other. In addition, the time information mentioned above is matched with the operating condition data and wind power condition data which are memorize | stored at this time. Thereafter, if there is a termination command for this program (S14: Yes), the processing is repeated (S11 to S13) if there is no termination command. Accordingly, the received operating state data and wind power state data are sequentially stored in each management device 1000 in a form associated with the wind power generator 1 of the transmission source.

  The normal range determination program 1005b executed by the control unit 1001 of each management apparatus 1000 will be described with reference to FIG.

  When the normal range determination program 1005b is executed, the control unit 1001 first determines the presence / absence of reception of wind state data transmitted from the wind turbine generator 1 determined as a management target (S101). When the wind state data is received, the source wind power generator 1 is identified based on the identification information associated with the data (S102), and the wind state (here, wind speed) is determined based on the wind state data. ) Is specified (S103). The storage device 1005 stores normal operation data information having various operation data values (hereinafter referred to as reference values) obtained when the wind turbine generator 1 is operating normally in various wind conditions (wind speeds). Since the data is stored, the reference value corresponding to the specified wind force state is specified based on the normal operation data information (S104). Then, a normal range including the specified reference value (a normal range of the operating state data that defines that the wind turbine generator 1 is operating normally) is determined in advance by a predetermined calculation method (for example, with respect to the reference point). The error range is determined and the error range is set as a normal range). (S105), and the normal range determined immediately before (with the same identification information) is determined based on the determined normal range. The data is overwritten and stored in the storage device 1005 (S106). This process is repeatedly executed within a predetermined period.

  The abnormality specifying program 1005c executed by the control unit 1001 of each management apparatus 1000 will be described with reference to FIG.

  When the abnormality identification program 1005c is executed, the control unit 1001 first determines whether or not the operating state data transmitted from the wind turbine generator 1 defined as a management target has been received (S201). When the operating state data is received, the source wind turbine generator 1 is specified based on the identification information associated with the data (S202), and the operating state data is stored in the storage device 1005. It is determined whether it is within the latest normal range (S203). Then, the control unit 1001 identifies the case where it is within the normal range as normal (S205), identifies the case where it is not within the normal range as abnormal (S207), and the result identified immediately before by the identification result (S207) However, the same identification information is overwritten and stored in the storage device 1005 (S206). This process is repeatedly executed within a predetermined period.

  In addition, this process is performed with respect to all the various operating state data, respectively, and when it is determined that all of them are normal, the wind power generator is specified as normal, and when any one is determined as abnormal The wind power generator is identified as abnormal. The storage device 1005 stores an abnormality / normality identification result for each operational state data identified by the abnormality identification program 1005c, while the output data 1005g is an abnormality / normality identification result of the operational state data. The normal / abnormal specification result of each wind turbine generator 1 specified based on the above is stored.

  When the first remote control program 1005c is executed, the control unit 1001 first determines whether there is an abnormality in the wind turbine generator 1 that is set as a management target in the storage information (output data 1005g) of the storage device 1005. If it is determined based on (S401) and it is determined that there is an abnormality (S401: Yes), the abnormal wind power generator 1 is specified (S402) and directed to the control unit 3000 of the specified wind power generator 1 Then, a forced stop command is transmitted (S403), and this process ends. This process is repeatedly executed within a predetermined period.

Since the user operation (forced stop cancellation operation) is performed by selecting a wind power generation apparatus 1 that is forcibly stopped to cancel the forced stop, first, the selected wind power generation apparatus 1 is specified ( S411). Then, it is determined whether or not the specified wind power generator 1 is normal (S412). If it remains abnormal, the display unit 1003 and the audio output unit 1004 notify that the user operation (forced stop cancellation operation) is invalid (S414). If it returns to normal, a forced stop cancellation | release instruction | command will be transmitted toward the control part 3000 of the specified wind power generator 1 (S413), and this process will be complete | finished.

  A second forced control program 3000b executed by the control unit 3000 of each wind turbine generator 1 in response to a forced stop cancellation command from the main management device 1000A will be described with reference to FIG. 12B.

  When the forcible control program 3000b is executed, the control unit 3000 executes drive control for the lock mechanism 620 (drive unit 622) of the brake device 600, and moves the lock member 621 from the lock position (right side of FIG. 4B). An unlocking operation for moving to the unlocking position (left of FIG. 4B) is executed (S44), and this process is terminated.

  An emission right value calculation program 1005d executed by the control unit 1001 of each management apparatus 1000 will be described with reference to FIG.

  When the emission right value calculation program 1005d is executed, the control unit 1001 first determines whether or not the power generation amount data transmitted from the wind turbine generator 1 defined as a management target has been received (S201). When the power generation amount data is received, the transmission source wind power generation device 1 is specified based on the identification information associated with the data (S202), and the received power generation amount data is determined in advance. Using the conversion formula, it is converted into a global warming gas reduction amount (here, carbon dioxide reduction amount) (S303), and the accumulated global warming gas reduction amount accumulated and stored in the storage device 1005 so far is obtained. Then, the converted global warming gas reduction amount is added, and the cumulative value of the global warming gas reduction amount stored in the storage device 1005 as output data 1005g is updated based on the result (S304). Further, the updated cumulative value of the global warming gas reduction amount of the wind turbine generator 1 or the cumulative power generation amount of the wind turbine generator 1 is converted into a predetermined value (price) of the global warming gas emission right. The global warming gas emission right value (global warming gas emission right price) is calculated using the conversion formula (S305). And the global warming gas emission right value memorize | stored in the memory | storage device 1005 as the data for output 1005g by the calculated global warming gas emission right value is updated, and this process is complete | finished. This process is repeatedly executed within a predetermined period.

  In S304, the cumulative value of the global warming gas reduction amount related to the wind power generation device 1 that is the transmission source of the power generation amount data is updated. Here, further, the global warming of all the wind power generation devices 1 defined as the management target is updated. The total value obtained by adding the cumulative value of the gas reduction amount shall be updated. In S305, the value of the global warming gas emission right related to the wind power generation device 1 that is the transmission source of the power generation data is updated. Here, the global warming of the all wind power generation device 1 determined as a management target is further updated. The total value added with the gas emission right value shall also be updated.

  The output program 1005e executed by the control unit 1001 of each management apparatus 1000 will be described with reference to FIG.

  The output program 1005e is executed by a predetermined user operation (output execution operation) to the input unit 1002 of the management apparatus 1000. When this is executed, the control unit 1001 first sets the value of the identification number N assigned sequentially from 1 to the wind power generators that are determined as management targets to N = 1 (S501). Next, it is determined whether the identification number N is the last number I of the identification number (S502). If it is not I, whether the wind turbine generator 1 with the identification number N is normal or abnormal at the present time? Is specified based on the storage information (output data 1005g) of the storage device 1005 (S503). Subsequently, whether the wind turbine generator 1 with the identification number N is currently generating power or is not generating power is stored in the storage information (the latest power generation amount data included in the received data 1005f) stored in the storage device 1005. Based on this (S504). Further, the current global warming gas reduction amount and the global warming gas emission right value of the wind turbine generator 1 with the identification number N are specified based on the storage information (output data 1005g) in the storage device 1005 (S505). . After that, N = N + 1 is set, and the processing of S502 to S505 is executed again. In S502, when the identification number N is the last number I of the identification number, the identification results (S503 to S505) of the wind turbine generators 1 (N = 1 to I) identified so far are stored in advance. The data is output in a predetermined format (S506).

  FIG. 15 is an output example of the specific result of each wind turbine generator 1 (N = 1 to I). Here, on a display such as a liquid crystal, each wind power generation device 1 (N = 1 to 5), as the respective power generation status, the case of normal power generation is round, normal but no wind is generated. When there is no triangle, it is displayed as a triangle, and when it is stopped due to an abnormality, it is displayed as a cross. The display unit 1003 is provided with a light source such as a lamp or LED corresponding to each wind power generator 1 (N = 1 to 5), and the above three types are identified by color. In the case of stopping, the light emission state other than the color may be emphasized so as to be different. For example, green and blue may be displayed when the power is normally generated, yellow when the power is normal but no wind is generated, and red may be displayed when the power is stopped due to an abnormality.

  FIG. 19 is a perspective view showing an embodiment of the wind turbine generator of the present invention. The wind turbine 3 of the wind turbine generator 1 shown in FIG. 19 is configured to receive wind power from the axial direction 2x (see FIG. 34) of the rotary shaft 2 and rotate around the rotary shaft 2 in a constant rotational direction. 30 or more are provided around the rotating shaft 2. The blades 30 are arranged at predetermined intervals around the rotation axis 2x and are formed in the same shape.

  The blade 30 is formed in a shape in which the wind receiving surface 30w is twisted so that a difference in flow speed occurs between the rotating shaft 2 side and the tip 30s side. Specifically, the blade 30 is formed in such a shape that the pitch becomes shallower toward the tip 30s side.

  Further, the blade 30 of the present invention includes a blade body 30T extending radially outward with respect to the rotating shaft 2, and a blade tip 30S extending from the outside of the blade body 30T to the opposite side to the constant rotation direction. And comprising. That is, the blade 30 has a shape in which the outer front end portion is bent in the direction opposite to the constant rotation direction, and has a shape that has a tail with respect to the rotation of the blade 30.

  The blade tip portion 30S has a shape that appears to bend and continue from the blade body portion 30T that extends linearly in a front view (FIG. 22) and a back view (FIG. 21). The blade tip 30S here is formed so as to continue smoothly from the outer peripheral side of the blade body 30T and extends linearly in front view (FIG. 22) and rear view (FIG. 21). From the outer peripheral side of the visible blade main body 30T, it is formed to look like a hook that is curved in an arc shape.

  Further, the blade tip 30S has a shape in which the tip 30s positioned opposite to the blade body 30T can be seen in a straight line in the front view (FIG. 22) and the back view (FIG. 21). In other words, the blade 30 has a shape in which a curved tip is cut into a straight line. The cut surface is formed to face the direction opposite to the constant rotation direction. Here, the tip 30s of the blade tip 30S has the constant rotation direction of the blade body 30T extending linearly in the radial direction with respect to the rotary shaft 2 in the front view (FIG. 22) and the back view (FIG. 21). It is formed in a shape that appears to be substantially parallel to the side end face (end edge portion) 30a.

  The back surface 30v of the blade 30 (the surface opposite to the wind receiving surface 30w) has a mountain shape at the center in the width direction so as to have a ridge line 30p along the blade extending direction from the blade main body 30T to the blade tip 30S. Convex part 30P is formed. Further, the convex portion 30P is provided at a position where the ridge line 30p is biased toward the rotation support shaft 33Z (see FIG. 35) of the blade fixing portion 33 described later in the width direction W of the back surface 30v.

It is made into the shape bent to the wind-receiving surface side (direction opposite to a wind receiving direction) of the part 30. FIG. With this bent shape, the blade 30 can easily receive wind at the bent portion. For this reason, it can rotate efficiently by the received wind. Also, the stress applied to the tip side (outer peripheral side) of the blade 30 can be resisted in such a manner that the blade tip side is in the wind receiving direction, and has a high strength structure. In addition, as described above, the tip end side (outer peripheral side) of the blade 30 is bent in the direction opposite to the rotation direction, so that the blade tip side resists the wind force even when the blade tip side is elastically twisted. Therefore, the structure has higher strength.

The wind direction fins 202 occupy a positional relationship perpendicular to the rotating surface of the windmill 3. The wind direction fin 202 includes a hypotenuse 203 having a length that is equal to or slightly shorter than the axial length of the case main body 201 and gradually increasing in height from the vicinity of the windward front end of the case main body 201 in an arc shape (or linear shape).

The rear end bulges in an arc shape or the rear end hangs down linearly), but the lower end thereof is continuous with the upper surface of the case body 201. Further, the wind direction fin 202 has a slanted side 203 that is sharpened like a knife edge, and has a curved surface that is sharper toward the rear end from the intermediate portion toward the rear end portion 204. The middle part is formed to be the thickest and has a sharp triangular shape as shown in FIG.

  On the opposite side (lower side) of the wind direction fin 202 across the axis of the case main body 201, a column connection part 208 is formed that connects to a column (pole) 110 that maintains the wind turbine 3 at a predetermined height. The column 110 is connected here. The column connecting portion 208 protrudes downward from the lower surface of the case body 201 and smoothly tapers, and the lower end portion is formed in a cylindrical shape. The upper end portion of the circular cross section of the column 110 is formed in the cylindrical portion. 27, the wind guide case 200 and the wind turbine 3 are rotatably supported around the axis (vertical axis) of the support 206 via a bearing 210 as shown in FIG. As a result, the wind turbine 3 and the wind guide case 200 are kept free so that the wind direction fins 202 formed in the wind guide case 200 follow the wind direction, in other words, the rotating surface of the wind turbine 3 always faces the wind direction.

The weight member 35 is located outward as the centrifugal force FA increases, and the weight member decreases as the centrifugal force decreases. The weight member 35 is displaced within a predetermined radial range so that 35 is positioned inward. In the present embodiment, as shown in FIGS. 40 and 42, the first link member 371 and the second link member 372 that are linked to each other are configured. In the first link member 371 formed in an L shape, the weight member 35 is integrally fixed to one end 371A by a fastening member, and one end 372A of the second link member 372 is fixed to the other end 371B. Are attached to each other in a form having a rotation axis 372y perpendicular to both the rotation axis 2x and its radial direction (radial direction in which the corresponding weight member 35 is displaced). The other end portion 372B of the second link member 372 is attached to the outer peripheral portion of the annular connection member 36 having a disk shape so as to have a rotation axis 373y parallel to the rotation axis 372y. In addition, the bent portion 371C positioned in the middle of the L-shaped first link member 371 is rotatably attached to the shaft fixing portion 221 so as to have a rotation axis 371y that is parallel to the rotation axis 372y. . The shaft fixing portion 221 is fixed integrally with the rotary shaft 2 and is not displaced with the movement of the weight member 35 in the radial direction. The shaft fixing portion 221 is used as a fixed link, and the first link. The member 371 and the second link member 372 are movable.

  The urging means 34 is a spring member (a tension spring) and is provided for each blade 30. As shown in FIGS. 40 and 42, the urging means 34 has one end at the blade in the shaft fixing portion 221. While being fixed on the surface opposite to the fixing portion 33, the other end is fixed on the facing surface side of the connecting member 36 facing in the direction of the rotation axis 2x. In the present embodiment, a spring fixing portion 221c (see FIG. 35A) for fixing one end of the spring member 34 is provided on the upstream surface of the shaft fixing portion 221 in the wind receiving direction. A spring fixing portion 36c (see FIGS. 37 and 39) for fixing the other end of the spring member 34 is provided on the surface on the downstream side in the direction. By providing a pair of spring fixing portions 221c and 36c in advance at a plurality of locations (here, three locations), it is possible to adjust the urging force by increasing the number of spring members 34.

  The connecting member 36 can be integrally rotated with respect to the rotary shaft 2 via the link mechanism 37 and the shaft fixing portion 221 and slides to the first side of the rotary axis 2x due to the radially inward displacement of the weight member 35. The bearing moves at the center so that it moves (see FIGS. 40 and 41) and slides to the second side of the rotation axis 2x due to the radially outward displacement of the weight member 35 (see FIGS. 42 and 43). It connects with the rotating shaft 2 through the apparatus. Here, the first side is the downstream side in the wind receiving direction (the shaft fixing portion 221 side), and the second side is the upstream side in the wind receiving direction.

  The connecting member 36 is directly or indirectly connected to the corresponding blade 30 so that the angle θ is closer to the wind parallel by the sliding movement of the rotation axis 2x toward the first side due to the radially inward displacement of the weight member 35. The pressing member 362 which is pressed against the blade 30 and pulled back directly or indirectly so that the angle θ approaches the wind orthogonal direction by the sliding movement of the rotation axis 2x to the second side due to the radially outward displacement of the weight member 35 is the blade 30 It is provided for each. Thus, the angle θ of each blade 30 is configured to be determined according to the position on the rotation axis of the connecting member 36 that slides as the weight member 35 moves inward and outward in the radial direction. As a result, the angles θ of the blades 30 change in such a manner that they are in synchronism with each other.

  Each pressing member 362 in FIGS. 40 to 43 is shown as a structure in which the corresponding blade 30 is directly pressed or pulled back, but in reality, as shown in FIG. A fixed portion 33A (here, on the upstream side in the wind receiving direction) that extends through a through hole 221h formed in the disk-shaped front end portion 221A and whose extended tip end is integrally fixed to the corresponding blade 30. It is fixed to a rotation fixing portion 330a) provided in the parallel plate portion 330A so as to be rotatable around an axis parallel to the axis 33z of the rotation support shaft 33Z. Here, the pressing member 362 is fixed so as to be rotatable with respect to the second side far from the rotation support shaft 33Z of the fixing portion 33A.

  Further, the weight member 35 has a predetermined movable range in the radial direction. The state shown in FIG. 42 is a state in which the weight member 35 is in the radially outermost position, and cannot be displaced further outward in the radial direction due to the configuration of the link mechanism 37. When the weight member 35 reaches this outermost position, the blade 30 reaches a predetermined high-speed rotation angular position B where the width direction W of the wind receiving surface 30w is closest to the wind orthogonal direction (see FIG. 44). ). On the other hand, the state of FIG. 40 is a state in which the weight member 35 is in the radially innermost position and cannot be displaced further inward in the radial direction. However, this is not the innermost position defined by the configuration of the link mechanism 37. That is, the innermost position is the abutting member 38 provided at a position facing the moving direction with respect to the movable structure that operates in conjunction with the angle changing operation of the blade 30 including the blade 30 toward the wind parallel direction. Is defined as a contact position. In the state shown in FIGS. 40 and 41 and FIG. 44 (a), the blade 30 is urged closer to the wind parallel by the pressing force FW by the wind force and the urging force FB by the urging means 34. And the angle changing operation of the blade 30 toward the wind parallel direction by the FB stops with the contact member 38 coming into contact with the movable structure operating in conjunction with the angle changing operation of the blade 30 including the blade 30. The stop position is the innermost position in the radial direction of the weight member 35, and the position of the blade 30 at the same time is the initial rotation angular position A.

  In the present embodiment, each blade fixing portion 33 is fixed to the rotating shaft 2 via a common fixing member fixed so as to be integrally rotatable with the rotating shaft 2, and the fixing member functions as the contact member 38. . Here, the shaft fixing portion 221 is the contact member 38. On the other hand, the connecting member 36 is connected to the link mechanism 37 so as to approach the fixed member as the width direction W of the blade 30 becomes closer to the wind parallel, and functions as the movable structure 39. An extension portion 380 that extends toward the other member is formed on one or both of the shaft fixing portion 221 that is the abutting member 38 and the connecting member 36 that is the movable structure 39. The leading end on the other member side of the protruding portion 380 contacts the contact portion 390 of the other member, so that the blade 30 is held at the angular position A for initial rotation. Here, the connecting member 36 is formed with a cylindrical portion or a protruding portion that extends from the center portion toward the shaft fixing portion 221 as an extending portion 380, and the tip of the connecting member 36 and the shaft fixing portion 221 are formed. The blade 30 is held at the initial rotation angular position A by the contact with the contact portion 390. At least one of the contact portion of the contact member 38 and the contact portion of the movable structure 39 is provided as an elastic member such as rubber. Here, the contact portion 390 of the shaft fixing portion 221 is provided as an elastic member.

  By having such a configuration, the blade 30 operates as shown in FIG.

  That is, when the wind force falls below a predetermined light wind level, as shown in FIG. 44A, the pressing force FW on the wind receiving surface 30w of the blade 30 by the wind force and the urging force FB of the urging means 34 are generated. By overcoming the centrifugal force FA and pressing the weight member 35 inward, the blade 30 is biased and held at the angular position A for initial rotation. More specifically, when the wind force falls below a predetermined light wind level, the movable structure 39 is pressed by the pressing force FW and the urging force FB so as to contact the contact member 38, and at the contact position. The blade 30 is held at a certain initial rotation angular position A. At this time, the width direction of the wind receiving surface of the blade 30 is closest to the wind parallel. This state is a state in which the windmill 3 is easy to obtain a high torque even with a small amount of wind power, and the windmill 3 is easy to rotate. However, it is difficult to obtain a high rotational speed.

  When the wind force exceeds the above-mentioned light wind level, as shown in FIG. 44 (b), the centrifugal force FA starts to increase, and the pressing force FW to the wind receiving surface 30w and the urging force FB of the urging means 34 The weight member 35 is displaced outward to a position where FA, FW, and FB are balanced, and the angle θ of the blade 30 also leaves the initial rotation angular position A and changes its position toward the wind orthogonal position. This state is a state in the middle of a transition to a state suitable for higher speed rotation, although it becomes difficult to obtain a higher torque as the position becomes closer to the wind.

  However, the outermost position of the weight member 35 is defined. When the wind force reaches a predetermined strong wind level that exceeds the above-described light wind level, the weight member 35 reaches its outermost position and cannot be displaced outward beyond that. At this time, the blade 30 reaches a predetermined high-speed rotation angular position B in which the width direction W is closest to the wind orthogonal direction. This state is a state in which the windmill 3 can rotate at the highest speed.

  When the wind force further exceeds the strong wind level, as shown in FIG. 44 (c), the pressing force FW to the wind receiving surface 30w by the wind force and the urging force FB of the urging means 34 are applied to the centrifugal force FA. By overcoming and then pushing the weight member 35 back inward, the blade 30 is returned so that the width direction W is closer to the wind. This state is a state in the middle of the transition of the wind turbine 3 to a state in which it is difficult to obtain a high rotational speed gradually. Here, the blade 30 can be returned to the initial rotation angular position A where the movable structure 39 contacts the contact member 38.

  As described above, according to the present embodiment, by having the biasing means 34, the weight member 35, and the link mechanism 37, the first stage in which the angle θ of the blade 30 is close to the wind parallel so that the blade 30 can be easily rotated in a light wind. And the second stage in which the angle θ of the blade 30 is close to the wind orthogonal so that high rotation is likely to occur when the wind speed increases, and the blade 30 from the wind orthogonal to the wind parallel so that over-rotation is prevented in a strong wind. It is possible to vary the angle θ of the blade 30 in the three stages of being pushed back, and the wind turbine 3 is excellent in starting performance by autonomous rotation speed control by changing the angle of the blade 30 in the three stages. Moreover, the efficiency at the time of high rotation is high, and the excessive rotation at the time of strong wind can be suppressed.

  Hereinafter, the structure of the wind power generator 1 provided with the above-mentioned windmill 3 is demonstrated. In addition, the wind power generator 1 of this invention is not restricted to the structure of this embodiment described below.

  The wind turbine generator 1 of the present embodiment has the above-described configuration, so that it receives wind power from a predetermined wind receiving direction 2w and rotates around a predetermined rotation axis 2x in a constant rotation direction (FIG. 19). 34 and 45), and when the rotating shaft 2 is accelerating in the constant rotation direction, the rotating shaft 2 is rotated integrally with the rotating shaft 2 and the rotating shaft 2 is rotated at an increased speed. When the vehicle is decelerating, it is provided with a flywheel 7 (see FIG. 48) disposed via a one-way clutch 6 (one-way clutch: see FIG. 48) so as to be separated from the rotary shaft 2 and rotate inertially. Further, here, the power generation has a rotor 91 (see FIG. 48) arranged to rotate integrally with the flywheel 7 so as to rotate integrally with the flywheel 7 and generates electric power by the rotation of the rotor 91 accompanying the rotation of the flywheel 7. Machine Configured with a means) 9 (see FIG. 45).

  More specifically, the generator 9 is a second generator, and has a rotor 51 that is arranged coaxially with the flywheel 7 so as to rotate integrally therewith, and the electric power is generated by the rotation of the rotor 51 as the flywheel 7 rotates. The first generator 5 that is different from the second generator 9 is generated. Here, as shown in FIG. 48, the 1st generator 5 is provided in the wind receiving direction downstream with respect to the flywheel 7, and the 2nd generator 9 is provided in the wind receiving direction upstream.

  And the wind power generator 1 of this embodiment receives both the electric power inputs produced | generated by the 1st generator 5 and the 2nd generator 9, as shown to FIG. 46A and FIG. 46B, and combines them. An output unit (output means) 10 that outputs externally is provided. In other words, the output lines of the generated power of the first generator 5 and the second generator 9 are connected until reaching the external output, and are configured to be externally output by one system.

  For example, as shown in FIG. 46A, the output unit 10 inputs both three-phase AC power generated by the first generator 5 and the second generator 9 to the rectifier 12, and then boosts the controller. 11 and output at a predetermined voltage, which is further input by the power conditioner 15, and the input DC power is converted into system power and output. Thereby, both the electric power produced | generated by the 1st generator 5 and the 2nd generator 9 can be combined, and can be supplied to the external power supply system 19A, for example, power sale etc. are attained. Further, the power conditioner 15 may convert the AC power that can be used in the home and output it. Further, as shown in FIG. 46B, the output unit 10 inputs both electric power generated by the first generator 5 and the second generator 9 to the rectifier 12 and then inputs to the boost controller 13. Alternatively, direct current power set to a predetermined voltage may be supplied to the battery (power storage means) 19B for storage. Further, the power stored in the battery (power storage means) 19B may be supplied to the external power supply system 19A via the power conditioner 15, or the power stored in the battery (power storage means) 19B may be supplied in a predetermined manner. You may use for the purpose.

  FIG. 47 is a cross-sectional view of the nacelle forming the air guide case 200 cut along a plane passing through the axes 2x and 110x. As shown in FIG. 47, the nacelle 200 changes its orientation in the horizontal plane in accordance with the wind direction with respect to the column main body 110S together with the upper end portion 110T of the column (tower) 110 extending from the foundation portion 190 (see FIG. 19) of the ground surface. (It can be rotated around the vertical axis 110x of the column main body 110S).

Similarly, the cylindrical intermediate storage space 7S is larger in diameter than the cylindrical upstream storage space 9S and the downstream storage space 5S, and the flywheel 7 itself to be stored is also the intermediate storage space 7S in the radial direction. Since the upstream storage space 9S and the downstream storage space 5S communicate with each other only on the outer peripheral side of the flywheel 7, when the flywheel 7 is disposed, It is surely separated. Thereby, the other space does not receive the influence of the turbulence of the air flow accompanying the rotation of the rotating body (rotor 91, 51) in one of the upstream housing space 9S and the downstream housing space 5S. .

It is done. In these cylindrical members 53 and 93, openings that penetrate in the radial direction are formed at predetermined intervals along the circumferential direction. These openings are partitioned by pillars extending in the axial direction of the rotary shaft 2 provided in the circumferential direction, and stator coils 54 and 94 are wound around the pillars. In the present embodiment, the winding direction is reversed between adjacent column portions.

  Although one embodiment of the present invention has been described above, this is merely an example, and the present invention is not limited to this, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible.

  For example, the embodiment described above can be modified as follows.

  The abnormality specifying program 1005c executed by the control unit 1001 of each management apparatus 1000 can be changed as shown in FIG. 16 instead of FIG.

  When the abnormality specifying program 1005c in FIG. 16 is executed, the control unit 1001 first determines whether or not the power generation amount data and the rotation speed data transmitted from the wind power generator 1 that are set as management targets are received ( S2001). If such data has been received, the source wind turbine generator 1 is specified based on the identification information associated with the data (S2002), and the power generation amount data and the rotational speed data are respectively Then, it is determined whether or not it is within the latest normal range stored in the storage device 1005 (S2003). Then, it is determined whether or not the rotation speed data is within the normal range (S2004), and the case where the rotation speed data is not within the normal range is identified as a rotational operation abnormal state (second abnormal state) (S2005). When the rotation speed data is within the normal range (S2004: Yes), it is determined whether the power generation amount data is within the normal range (S2007). State) is specified (S2008). When the power generation amount data is within the normal range, both the power generation amount data and the rotation speed data are specified as normal (S2009). Then, the result obtained in any one of S2005, S2008, and S2009 is stored in the storage device 1005 in the form of overwriting the same identification information among the results specified immediately before (S2006). This process is repeatedly executed within a predetermined period.

  In this case, when the output program 1005e is executed, an output display image as shown in FIG. 17 is executed. That is, in FIG. 17, the normal / abnormal identification result for each wind turbine generator 1 to be managed is identified as a power generation abnormal state (first abnormal state) and a rotational operation abnormal state (second abnormal state). Output is possible.

  Each wind power generator 1 can be configured as shown in FIG.

A storage amount detection unit 706 that detects the storage amount of the battery 900 is provided, and the control unit 3000 transmits storage amount data indicating the detected storage amount to the management apparatus 1000. Then, the management device data can identify the wind power generation device in which the power storage amount indicated by the power storage amount data is equal to or lower than a predetermined level as abnormal. Thereby, it is possible to forcibly stop the wind turbine generator that is in a state in which it is difficult to obtain and transmit various operating state data.

The forced stop command in this case is output to the selected wind power generator 1 based on a predetermined forced stop operation to the input unit 1002 which is made by the user selecting the wind power generator 1 to be forcibly stopped. You can make it.

  The brake device 600 may be configured to be used only when the wind power generator 1 installed at a location where a strong wind of a predetermined strong wind level or higher is predicted is forcibly stopped.

In other words, the generated power generated by the first generator 5 and the second generator 9 and having different phases from each other is externally output by one system. In this case, the configuration of the output unit 10 can be the same as that shown in FIGS. 46A and 46B.

  Moreover, the angle adjustment mechanism 300 in the said embodiment can be changed as follows.

  That is, in the angle adjustment mechanism 300 in the above embodiment, as the urging means 34, the width direction W of the wind receiving surface 30w of the blade 30 is positioned between the initial rotation angular position A and the high speed rotation angular position B. The spring member 34 is used to urge the blade 30 toward the angle position A for initial rotation with a constant urging force so that the width direction W is closer to the wind parallel side. The biasing force that biases the width direction W of the wind surface 30w toward the initial rotation angular position A may be changed to increase as the distance from the initial rotation angular position A increases. Hereinafter, the angle adjustment mechanism 300 ′ and the windmill 3 ′ different from those in the above embodiment will be described with reference to FIGS. 51 to 58.

  FIG. 51 shows a wind turbine 3 ′ different from the wind turbine 3 of the above embodiment. 52A is an enlarged partial sectional view of one plate fixing portion in FIG. 51. FIGS. 52B and 52D are cross-sectional views taken along line AA in FIG. 52A. 52 (c) and 52 (e) are schematic views schematically showing the BB cross section of FIG. 52 (a). However, the angle θ formed by the width direction W of the blade 30 and the direction of the rotation axis 2x differs between FIGS. 52 (b) and 52 (d) and FIGS. 52 (c) and 52 (e). (B) and (d) of FIG. 52 show a state in which the blade 30 is close to the wind orthogonal direction, and FIGS.

  51. As shown in FIGS. 52 to 56, an angle adjusting mechanism 300 ′ of the wind turbine 3 ′ shown in FIG. 51 is replaced with a magnet (such as a neodymium magnet) instead of the spring member 34 used as the biasing means in the embodiment of FIG. Magnetic members) 340a and 340b are different. The magnet 340b receives the wind of the blade (movable structure) 30 that can change the angle θ between the width direction W of the wind receiving surface 30w (see FIGS. 57 and 58) and the direction of the rotation axis 2x of the rotary shaft 2. Mounted upstream in the direction. More specifically, of the parallel plate portions 330A and 330A constituting the blade attachment member (movable structure) 330 for attaching the blade 30, it is directly fixed to the parallel plate portion 330A on the upstream side in the wind receiving direction by a fastening member. On the other hand, the magnet 340a is attached to a shaft fixing portion (fixed structure portion) 221 that approaches the parallel plate portion 330A (blade 30), to which the magnet 340b is attached, closer to the wind orthogonal direction, facing the magnet 340b. . Specifically, the shaft fixing portion (fixed structure portion) 221 is directly fixed to the downstream side in the wind receiving direction by the fastening member. The opposing magnets (magnetic members) 340a and 340b have the same polarity and generate a repulsive force FM (see FIGS. 57 and 58) that prevents the mutual approach when approaching. The repulsive force FM increases as the distance between the opposing magnets (magnetic members) 340a and 340b decreases.

  By having such a configuration, the blade 30 operates as shown in FIGS. 57 and 58.

  That is, when the wind force falls below a predetermined light wind level, as shown in FIG. 57A, the pressing force FW on the wind receiving surface 30w of the blade 30 by the wind force and the urging force FM of the urging means 340a and 340b. Overcomes the centrifugal force FA and presses the weight member 35 inward, so that the blade 30 is biased and held at the angular position A for initial rotation. More specifically, when the wind force falls below a predetermined light wind level, the movable structure 39 is pressed by the pressing force FW and the urging force FB so as to contact the contact member 38, and at the contact position. The blade 30 is held at a certain initial rotation angular position A. At this time, the width direction of the wind receiving surface of the blade 30 is closest to the wind parallel. This state is the same as that shown in FIG. 44 (a), but here the urging force FM is the repulsive force of the magnets 340a and 340b, and here the urging force is long because the distance between the magnets 340a and 340b is long. FM is much smaller than the urging force FB in FIG. 44 (a) and acts as an extremely small force.

  When the wind power exceeds the above-mentioned light wind level, as shown in FIG. 57 (b), the centrifugal force FA starts to increase, the pressing force FW on the wind receiving surface 30w and the urging forces of the urging means 340a and 340b. Overcoming FM, the weight member 35 is displaced outward to a position where the FA, FW and FM are balanced, and the angle θ of the blade 30 is also away from the initial rotation angular position A and closer to the wind orthogonal position. change. This state is the same as FIG. 44B, but the urging force FM here is still much smaller than the urging force FB.

  When the wind power reaches a predetermined strong wind level that exceeds the above-described light wind level, the blade 30 has a width direction W that is perpendicular to the wind angle relative to the initial rotation angular position A, as shown in FIG. It will be in the state which reached | attained the predetermined angular position B for high-speed rotation which becomes near. This state is a state in which the windmill 3 can rotate at the highest speed. At this stage, the distance between the facing magnets (magnetic members) 340a and 340b facing each other becomes smaller, so that the urging force FM gradually increases to have a function as the urging force.

  When the wind force further exceeds a predetermined strong wind level, as shown in FIG. 58 (d), the centrifugal force FA further increases, and the angle θ of the blade 30 exceeds the angular position B for high-speed rotation. This is the position on the wind orthogonal plane Y side. In the range of the angle θ of the blade 30 beyond the angular position B for high-speed rotation (hereinafter referred to as “rotational deceleration angle range”) Q, the blade 30 that has been a positive pitch until now has a negative pitch, The reverse rotational force is generated. In other words, the blade 30 is configured to rotate in a predetermined constant rotation direction that receives the wind force from the wind receiving direction 2w and rotates. If it exceeds, the reverse direction rotational force which tries to rotate in the direction opposite to the constant rotational direction is generated. The reverse direction rotational force increases as the distance from the high-speed rotation angular position B increases within the rotation deceleration angular range Q. For this reason, the blade 30 positioned in the rotation deceleration angle range Q is in a state where the rotation in the constant rotation direction is braked, the rotation speed is reduced, and the centrifugal force FA of the weight member 35 is also reduced accordingly. To do. On the other hand, the urging force FM of the urging means 340a, 340b increases as the blade 30 located in the rotation deceleration angular range Q moves away from the high-speed rotation angular position B. For this reason, the blade 30 positioned in the rotation deceleration angular range Q is again pushed back to the high-speed rotation angular position B, and the FA at that time, and the FW and FM are in a balanced position.

  As described above, the angle adjusting mechanism 300 ′ includes the urging means 340a and 340b, the weight member 35, and the link mechanism 37, so that the angle θ of the blade 30 is made closer to the wind parallel so that it can be easily rotated in a light wind. One stage, a second stage in which the angle θ of the blade 30 is close to the direction perpendicular to the wind so that high rotation is likely to occur when the wind speed increases, and an angle θ of the blade 30 for rotational deceleration so that over-rotation is prevented during strong winds. It is possible to vary the angle θ of the blade 30 in the three stages of reaching the angle range. By the autonomous rotational speed control by changing the angle of the blade 30 in the three stages, the wind turbine 3 ′ It has excellent startability, high efficiency at high rotation, and suppression of excessive rotation during strong winds.

  Note that the angular position B for high-speed rotation of the blade 30 in FIG. 44 already described is located before reaching the wind orthogonal plane Y, which is the maximum value of the centrifugal force FA and the magnitude of the constant urging force FB. The true angular position for high-speed rotation at which the wind turbine can rotate at the highest speed may be further on the wind orthogonal plane Y side than the movable limit position. However, as shown in FIG. 44, the movable limit angle position of the blade 30 defined by the maximum value of the centrifugal force FA and the magnitude of the constant urging force FB is defined as a position D that coincides with the wind orthogonal plane Y, and this position. It is most desirable in terms of rotational performance that D be an angular position for high-speed rotation. On the other hand, the embodiment described with reference to FIGS. 57 and 58 is configured such that the FA does not become maximum even when the angular position of the blade 30 exceeds the position B as shown in FIG. Here, the movable limit angle position of the blade 30 exists at a position on the back side of the wind orthogonal plane Y in a form defined by the magnitude of the magnetic force (magnetic repulsive force) of the magnets 340a and 340b. .

  In addition, although the blade 30 employ | adopted in this embodiment (magnet specification) may employ | adopt the thing of the shape of FIGS. 20-26 in the said embodiment (spring specification), here FIG. The shape is different from that of the shape. Specifically, the top view (plan view) and the bottom view (bottom view) of the blade 30 shown in FIGS. 25 and 26 are changed to be visually recognized as shown in FIGS. 49 and 50. 49 and 50, when the blade 30 is viewed from the same viewpoint as in FIGS. 20 to 24, a difference in appearance appears, but the difference is only a subtle difference. Since it is visually recognized in the same manner as in FIGS. 20 to 24, illustration is omitted.

  The blade 30 employed in the wind turbine of the wind power generator according to the present invention receives a wind force from the wind receiving direction 2w and rotates in a constant rotation direction so that a difference in flow speed occurs between the rotating shaft 2 side and the tip side. Thus, the wind receiving surface 30w is formed in a form in which a twist is applied from the rotating shaft 2 side to the tip side. In the embodiment already described, as shown in FIGS. 20 to 26, the wind receiving surface 30 w is configured such that the blade 30 is moved from the opposite side in the rotational direction with the width direction W of the blade 30 positioned on the wind orthogonal surface Y. When viewed (see FIG. 26), it can be seen while the surface width decreases from the rotating shaft 2 side to the tip side, and conversely, the width direction W of the blade 30 is positioned on the wind orthogonal surface Y. When the blade 30 is viewed from the rotational direction side in this state (see FIG. 25), the torsional shape is invisible. In this case, even if the angular position of the blade 30 changes between the position A and the position B, the wind receiving surface 30w can always be seen when the blade 30 is viewed from the opposite side of the rotation direction, and the blade 30 can be viewed from the rotation direction side. The wind receiving surface 30w cannot always be visually recognized (plus pitch). Therefore, when the blade 30 receives wind force from the wind receiving direction 2w, the wind force acts in such a manner as to press the wind receiving surface 30w viewed from the opposite side of the rotation direction, and always obtains rotational force in a constant rotation direction. Rotate.

  On the other hand, the blade 30 employed in this embodiment has the wind receiving surface 30w when viewed from the opposite side in the rotational direction with the width direction W positioned on the wind orthogonal surface Y (see FIG. 50). The shape is such that it can be seen only to an intermediate position on the way from the rotating shaft 2 side to the tip end side, and when the blade 30 is viewed from the rotational direction side in the same state from the intermediate position to the outside (FIG. 49). Reference) The wind receiving surface 30w has a torsional shape so that the wind receiving surface 30w can be visually recognized on the tip side of the blade 30. In this case, the blade 30 has a wind receiving surface when the blade 30 is viewed from the opposite side in the rotational direction in a state where the width direction W is positioned at a position B slightly before the position A on the wind orthogonal surface Y. Although 30w is visually recognized and the wind receiving surface 30w is not visually recognized when viewed from the rotation direction side (plus pitch), when the position B is exceeded, the wind receiving surface 30w is visually recognized on the tip side when viewed from the rotation direction side. (Minus pitch). For this reason, in the state where the blade 30 is located at the position B, the wind turbine 3 ′ can rotate at the highest speed, but reaches the angle range (rotational deceleration angular range) Q beyond the position B. Then, when the wind force is received from the wind receiving direction 2w, the wind force acts in such a manner as to press the wind receiving surface 30w that is visually recognized when the blade 30 is viewed from the opposite side of the rotation direction, and in the constant rotation direction. In addition to rotating with the rotational force, the wind force acts on the wind receiving surface 30w that is visually recognized when the blade 30 is viewed from the rotation direction side, so that it is opposite to the constant rotation direction. The rotational force is also obtained. As a result, the blade 30 enters a decelerated rotation state in which the brake is acting. When the blade 30 exceeds the position B, the wind receiving surface 30w can be visually recognized from the front end side when viewed from the rotational direction side. The area increases in such a way that the wind receiving surface 30w can be visually recognized, and the reverse rotational force increases.

  In addition, the angle adjustment mechanisms 300 and 300 ′ in the above embodiment can be modified into shapes as shown in FIGS. 60 and 61.

  FIG. 60 is a modification of the angle adjustment mechanism 300 described with reference to FIGS. 34 to 44, the biasing means 34 constituting the spring member has one end fixed to a movable structure (here, a connecting member) 36 that operates in conjunction with the change in the angle of the blade 30, and the other end. The end portion is a tension spring fixed to a fixed structure (here, a shaft fixing portion) 221 that is integrally fixed to the rotary shaft 2 and does not operate in conjunction with a change in the angle of the blade 30, and the blade 30 is initially rotated. The movable structure 36 that is moving away from the fixed structure 221 as it is displaced from the working angle position A in the direction perpendicular to the wind acts to pull the movable structure 36. On the other hand, in the angle adjusting mechanism 300 of FIG. 60, one end of the biasing means 34 ′ forming the spring member is fixed to the movable structure (here, blade mounting member) 330 similar to the above, while the other Is a compression spring fixed to a fixing structure (here, a shaft fixing portion) 221 similar to the above, and the fixing structure is fixed as the blade 30 is displaced from the initial rotation angular position A in the direction perpendicular to the wind. The movable structure 36 that approaches the body 221 acts to push back.

  61 is a modification of the angle adjustment mechanism 300 described with reference to FIGS. 51-58, one of the magnets 340b of the biasing means 340a, 340b forming a magnet is fixed to a movable structure (here, a blade mounting member) 330 that operates in conjunction with a change in the angle of the blade 30. The other magnet 340a does not operate in conjunction with the change in the angle of the blade 30, and is fixed to a fixed structure (here, a shaft fixing portion) 221 that is integrally fixed to the rotary shaft 2, and the magnets 340a and 340b. Are arranged in such a manner that those of the same polarity are opposed to each other, and with respect to the movable structure 330 that approaches the fixed structure 221 as the blade 30 is displaced from the initial rotation angular position A in the wind orthogonal direction. It produces a repulsive force and acts in a way that prevents its approach. On the other hand, in the angle adjustment mechanism 300 of FIG. 61, one of the magnets 340b ′ out of the biasing means 340a ′ and 340b ′ forming the magnet is fixed to the movable structure (here, the connecting member) 36 similar to the above. The other magnet 340b is fixed to the same fixed structure (shaft fixing portion in this case) 221 as described above, and the magnets 340a and 340b are arranged in such a manner that different poles face each other. As the blade 30 is displaced from the initial rotation angular position A in the direction perpendicular to the wind, a suction force is generated on the movable structure 330 that is separated from the fixed structure 221, and acts to prevent the separation. .
