(Embodiment 1)
FIG. 1 is a front view showing a configuration when the power generation apparatus according to the embodiment of the present invention is installed on land. In the power generation apparatus 1 shown in FIG. 1, a plurality of detour prevention plates 5 that are opposed to each other in the vertical direction are supported by a support column 6, and a single vertical protection plate 5 is passed through the detour prevention plates 5 in the vertical direction. A rotating shaft 2 is provided. The upper end of the vertical rotation shaft 2 is supported so as to be rotatable around the axis by a shaft receiver 24 having a built-in brake for adjusting the rotation speed, and the lower end is connected to the generator 10 via the gear box 11. Yes. The gear box 11 appropriately increases or decreases the rotation speed of the longitudinal rotation shaft 2 and transmits the rotation output to the generator 10. The shaft receiver 24 is installed on the upper surface of the uppermost detour prevention plate 5, and the gear box 11 and the generator 10 are installed on the lower surface of the lowermost detour prevention plate 5. Further, in the power generation device 1 shown in FIG. 1, the gear box 1 and the generator 10 are also installed in the middle of the vertical rotation shaft 2, more specifically, the lower surface of the fourth detour prevention plate 5 from the bottom. However, the number of rotations of the longitudinal rotation shaft 2 is increased or decreased as appropriate, and the rotation output is transmitted to the generator 10.

  One or a plurality of rotating body units 1a are provided between the detour prevention plates 5 that are opposed to each other in the vertical direction. In the case of the power generator 1 shown in FIG. 1, specifically, a total of six detour prevention plates 5 are provided from the bottom to the top, and the second sheet is between the first and second sheets from the bottom. Between the first and third sheets, and between the third and fourth sheets, one rotating body unit 1a (three bodies in total) is provided. In addition, two rotating body units 1a are provided between the fourth and fifth sheets, and four rotating body units 1a are provided between the fifth sheet and the uppermost sixth sheet. . However, the power generation device 1 according to the present invention is not limited to this configuration, and the total number of the rotating body units 1a, the number of the rotating body units 1a provided between the upper and lower detour prevention plates 5 and the like can be appropriately changed.

  FIG. 2 is a cross-sectional view taken along the line AA of the power generator 1 shown in FIG. FIG. 3 is a perspective view of the rotating body unit 1a, and FIG. 4 is a perspective view showing a part of the rotating unit 1a. As shown in FIGS. 2 and 3, the rotating body unit 1 a has a horizontal and cross shape with respect to the longitudinal rotation shaft 2 provided through the center hole of the regular hexagonal detour prevention plate 5 in plan view. In this way, two laterally rotating shafts 3 are provided. More specifically, a hole that penetrates the diameter portion is formed in the vertical rotation shaft 2, and one horizontal rotation shaft 3 is provided therethrough, and a bearing is provided between the hole and the horizontal rotation shaft 3. 9 is interposed (see FIG. 4). Further, in the vicinity of the hole in the vertical rotation shaft 2 (in the vicinity of the vertical direction), another hole that is orthogonal to the hole and penetrates the diameter portion of the vertical rotation shaft 2 is formed. In the same manner, the other lateral rotation shaft 3 is also provided through this hole through a bearing 9. As a result, the rotating body unit 1a has two horizontal rotating shafts 3 arranged in a cross shape in plan view, and these can rotate around their own axis 3a with respect to the vertical rotating shaft 2. Furthermore, when the vertical rotation shaft 2 rotates around its axis 2a, it rotates with the vertical rotation shaft 2.

  As shown in FIG. 4 and the like, the pressure receiving rotary blades 4 are attached via angle adjusting tools 29 to both sides of each horizontal rotary shaft 3 across the vertical rotary shaft 2. The pressure receiving rotary blade 4 has a long rectangular plate shape along the horizontal rotation shaft 3, and is attached to the horizontal rotation shaft 3 by the angle adjuster 29 (more precisely, the axial center of the horizontal rotation shaft 3). The angle around 3a is adjustable. In the rotating body unit 1a according to the present embodiment, the pressure receiving rotary blades 4 on both side portions of the horizontal rotating shaft 3 are adjusted to form an angle of about 90 degrees with each other. As will be described later, the pressure receiving rotary blade 4 receives a large amount of wind or tidal pressure in the horizontal direction when its main surface is along the vertical direction. For convenience, the posture of the pressure receiving rotary blade 4 at this time Is referred to as “pressure receiving posture” below. On the other hand, when the main surface is set along the horizontal direction, the pressure of the wind force or the tidal current is not so much received. For convenience, the posture of the pressure receiving rotary blade 4 at this time is hereinafter referred to as “non-pressure receiving posture”.

  Here, the pressure receiving rotary blade 4 will be described with reference to the pressure receiving posture. The pressure receiving rotary blade 4 has a blade head portion 4a as an upper portion and a blade tail portion 4b as a lower portion with respect to the mounting position of the lateral rotation shaft 3. It is divided into and. The pressure-receiving rotary blade 4 is laterally moved at a position above the center of the width dimension in the vertical direction of the pressure-receiving rotary blade 4 so that the vertical dimension of the blade head 4a is smaller than the vertical dimension of the blade tail portion 4b. Attached to the rotating shaft 3. In addition, a rotation guide inclined surface 18 that forms a surface inclined with respect to the main surface is formed at the tip portion of the pressure-receiving rotary blade 4 (the portion that is separated from the vertical rotation shaft 2). More specifically, a head rotation induction inclined surface 18a is formed at the tip of the blade head 4a, and a tail rotation induction inclined surface 18b is formed at the tip of the blade tail 4b. As shown in FIG. 3, these inclined surfaces 18 a and 18 b are inclined in directions opposite to each other with respect to the main surface of the pressure-receiving rotary blade 4, and both are bent at an acute angle and the same angle with respect to the main surface. It has a configuration like this. In addition, what is necessary is just to set this inclination angle suitably according to the environment (wind power or tidal current) etc. of the installation place of the electric power generating apparatus 1, and you may make the inclination angles of inclined surface 18a, 18b mutually differ.

  As shown in FIG. 3, bearings 9 different from those described above are attached to both ends of the lateral rotation shaft 3. Further, as shown in FIG. 2, the rotating body unit 1a is provided with the bearing 9 in order to prevent the end portion of the horizontal rotating shaft 3 from fluttering up and down when the vertical rotating shaft 2 rotates around the axis 2a. A guide rail 17 for guiding is provided. The guide rail 17 has an annular shape that is concentric with the longitudinal rotation shaft 2, and is supported from six directions by the column 6. In addition, as shown in FIG. 5 which is an enlarged perspective view of the vicinity of the end portion of the horizontal rotation shaft 3, a total of four bearings 9 attached to each end portion of the two horizontal rotation shafts 3 assembled in a cross shape are mutually connected. You may provide the connection ring 26 so that it may connect. The guide rail 17 may be formed in a groove shape whose cross section opens inward, and the bearing 9 and the connecting ring 26 may be positioned in the groove. In addition, the guide rail 17 according to the present embodiment is provided with a heating device (not shown), and can prevent icing when installed in a cold region.

  As shown in FIGS. 2 and 3, the rotating body unit 1 a includes a rod-shaped stopper 7 that regulates the rotation range around the shaft core 3 a of the pressure-receiving rotating blade 4. The stopper 7 is configured to extend from the peripheral surface of the vertical rotation shaft 2 to the end portion along the horizontal rotation shaft and downward, and bend in the middle to reach the bearing 9 at each end portion. Has been. In the case of the rotating body unit 1a according to the present embodiment, the pressure receiving rotary blade 4 is assumed to rotate within a range of about 90 degrees between the pressure receiving posture and the non-pressure receiving posture. The rotary blade 4 is regulated so as to rotate within the assumed rotation range. As described above, since one pressure receiving rotary blade 4 is in contact with the stopper 7 since one pressure rotating rotary blade 4 is provided so as to form approximately 90 degrees with respect to one horizontal rotating shaft 3 as described above. When in the pressure receiving posture, the other pressure receiving rotary blade 4 is not in contact with the stopper 7 and is in the non-pressure receiving posture.

  As shown in FIG. 3, the rotating body unit 1 a as described above receives the wind from the horizontal direction, and the head rotation induction inclined surface 18 a and the tail rotation induction inclined surface of the pressure receiving rotary blade 4 positioned most upwind. Pressure acts on one surface of 18b. As a result, the pressure receiving rotary blade 4 rotates together with the horizontal rotation shaft 3 around the horizontal axis 3a so as to be in a pressure receiving posture, and further around the vertical axis 2a (that is, centering on the vertical rotation shaft 2). Rotate). Further, in the pressure receiving rotary blade 4 located at the most leeward side, wind pressure acts on the other surface of the head rotation induction inclined surface 18a and the tail rotation induction inclined surface 18b. Therefore, since the pressure receiving rotary blade 4 rotates together with the horizontal rotation shaft 3 around the horizontal axis 3a so as to be in a non-pressure receiving posture, it further rotates around the vertical rotation shaft 2 and moves upward. Wind resistance (wind pressure) is reduced. Thus, the rotator unit 1a can convert the wind force from the horizontal direction into a rotational force that rotates the longitudinal rotation shaft 2 in a predetermined direction. Note that the conversion of wind power into rotational force is the same when the pressure of tidal current is received instead of wind.

  Thus, the pressure receiving rotary blade 4 rotates by receiving wind, and the rotation range of the pressure receiving rotating blade 4 is restricted between the pressure receiving posture and the non-pressure receiving posture by the stopper 7. Here, a buffer is provided on the pressure receiving rotary blade 4 in order to mitigate the impact generated when the rotated pressure receiving rotary blade 4 contacts the stopper 7. FIG. 6 is a schematic diagram for explaining a buffer provided on the pressure-receiving rotary blade 4. As shown in FIG. 6, one end of a buffer plate spring 13 that constitutes a shock absorber is connected to both the main surfaces of the pressure-receiving rotary blade 4, and the other end is separated from the main surface. ing. When the pressure receiving rotary blade 4 is in the pressure receiving posture or the non-pressure receiving posture, the buffer plate spring 13 comes into contact with the stopper 7 before the pressure receiving rotary blade 4, and the impact is relieved by the elastic force. .

  In the example shown in FIG. 6, the stopper 7 includes a rod-like body extending downward along the lateral rotation shaft 3 and a rod-like body extending laterally along the lateral rotation shaft 3. Is shown. Therefore, when the pressure receiving rotary blade 4 is in the pressure receiving posture (state shown by the solid line in FIG. 6), the buffer plate spring 13 attached to one main surface is attached to the stopper 7 positioned below the horizontal rotation shaft 3. In the case of contact and a non-pressure-receiving posture (state indicated by a two-dot chain line in FIG. 6), the buffer plate spring 13 attached to the other main surface is placed on the stopper 7 located on the side of the lateral rotation shaft 3. In any case, the impact can be reduced. Further, when attention is paid to the two pressure-receiving rotary blades 4 attached to one horizontal rotary shaft 3 penetrating the vertical rotary shaft 2, one of the two pressure-receiving rotary blades 4 is in a pressure-receiving posture as described above. The other is in a non-pressure-receiving posture. Accordingly, when the lateral rotation shaft 3 rotates and one pressure receiving rotary blade 4 assumes a pressure receiving posture, the buffer plate spring 13 contacts the lower stopper 7 and the other pressure receiving rotary blade 4 assumes a non-pressure receiving posture. Thus, the buffer plate spring 13 contacts the side stopper 7. In this way, the two pressure-receiving rotating blades 4 attached to one horizontal rotating shaft 2 are so designed that the shock-absorbing plate spring 13 is in contact with the stopper 7 at the same time. can do. However, as shown in FIG. 3, when the stopper 7 is composed only of a rod-like body extending below the horizontal rotation shaft 3, the buffer plate spring 13 provided on one main surface that is in contact with the pressure receiving posture. Only need to have.

  As shown in FIG. 1, the power generation device 1 according to the present embodiment includes a plurality of the rotating body units 1a described above, and the longitudinal rotating shaft 2 of the rotating body unit 1a disposed in the vertical direction. Is common. Therefore, the wind force from the horizontal direction can be efficiently converted into the rotational force of the longitudinal rotation shaft 2. Further, a plurality of detour prevention plates 5 are provided to suppress the change of the wind direction from the horizontal direction in the vertical direction, so that the wind force from the horizontal direction can be more efficiently converted to the rotational force of the vertical rotation shaft 2. Can be converted to

  Moreover, in the electric power generating apparatus 1 shown in FIG. 1, the blade | wing connection rod 27 is provided between the rotary body units 1a arranged in parallel up and down without interposing the detour prevention board 5 in between. That is, between the upper two detour prevention plates 5 among the six detour prevention plates 5 arranged in the vertical direction, as described above, the four rotating body units 1a arranged in the vertical direction are provided. ing. And the pressure receiving rotary blade 4 which each of these rotary body units 1a has is connected by the blade connection rod 27. More specifically, the upper end of the blade connecting rod 27 is pivotally supported by the blade tail portion 4b of the pressure receiving rotary blade 4 included in the upper rotary body unit 1a among the two upper and lower rotary body units 1a. The lower end is pivotally supported by the blade tail portion 4b of the pressure receiving rotary blade 4 of the rotary body unit 1a.

  Further, the blade connecting rod 27 is pivotally supported at two locations in the longitudinal direction with respect to one pressure receiving rotary blade 4. Further, in the present embodiment, the blade coupling is performed with respect to each of the two pressure receiving rotary blades 4 attached to any one of the two horizontal rotation shafts 3 included in the rotating body unit 1a. A rod 27 is pivotally supported, and the blade connecting rod 27 is not pivotally supported with respect to the two pressure-receiving rotary blades 4 attached to the other lateral rotation shaft 3. Therefore, in the power generator 1 of FIG. 1, a total of 12 blade connecting rods 27 are attached to the four rotating body units 1a. However, the blade connecting rod 27 may be pivotally supported with respect to all of the four pressure-receiving rotary blades 4 included in the rotating body unit 1a.

  By providing the blade connecting rod 27 as described above, the connected pressure receiving rotary blade 4 rotates in conjunction with the vertical rotation shaft 2 and rotates in conjunction between the pressure receiving posture and the non-pressure receiving posture. Therefore, the horizontal wind force can be efficiently converted into the rotational force of the longitudinal rotation shaft 2. In addition to the four rotating body units 1a described above, the power generation device 1 in FIG. 1 also applies blades to the two rotating body units 1a located between the second and third detour prevention plates 5 from above. A connecting rod 27 is provided. Therefore, the wind power can be efficiently converted into the rotational force in the same manner as described above for these two rotating body units 1a.

(Modification 1)
FIG. 7 is a view showing a first modification of the power generation device 1, and FIG. 8 is a cross-sectional view taken along the line DD of the power generation device of FIG. In the power generation device 1 according to the first modification, three blade connecting rods 27 are pivotally supported on the respective blade tail portions 4b with respect to the pressure receiving rotary blades 4 corresponding to each other of the upper and lower rotating body units 1a. Further, three blade connecting rods 27 are also pivotally supported on the blade heads 4a of the pressure receiving rotary blades 4 arranged vertically. Each blade connecting rod 27 has a configuration in which an upper portion and a lower portion are curved in the same direction, and end portions thereof are pivotally supported by a blade head portion 4a or a blade tail portion 4b.

  With such a configuration, the upper and lower pressure-receiving rotating blades 4 can be rotated and rotated more reliably in conjunction with each other. Further, since the upper and lower portions of the blade connecting rod 27 are curved, it is possible to prevent the intermediate portion from interfering with the lateral rotation shaft 3 when the pressure receiving rotary blade 4 is in the pressure receiving posture.

(Modification 2)
FIG. 9 is a drawing showing a second modification of the power generation apparatus 1, and FIG. 10 is a cross-sectional view taken along the line EE of FIG. The power generation apparatus 1 according to the second modification includes a pressure relief mechanism 400 for releasing a strong pressure exceeding a predetermined level received from a strong wind or the like in the blade tail portion 4b of the pressure receiving rotary blade 4. That is, for example, in the pressure receiving posture as shown in FIG. 9, a rectangular cutout window 400a is formed at the lower edge of the blade tail portion 4b. The notched window 400a is provided with horizontally-extended pressure-free blades 401, 402 vertically, and the upper end of the upper pressure-free blade 401 has an elastic member (for example, a coil spring) at the upper edge of the notched window 400a. (Or a leaf spring) 28, and the lower pressure-free blade 402 has an upper end connected to the lower end of the upper pressure-free blade 401 via the elastic member 28.

  With this configuration, when the pressure-receiving rotary blade 4 receives a relatively strong wind from the horizontal direction as shown in FIG. 9, the two pressure-free blades 401 and 402 connected by the elastic member 28 are It becomes downstream from the part 4b. Therefore, a part of the pressure received by the pressure receiving rotary blade 4 can be released, and the pressure received by the pressure receiving rotary blade 4 can be prevented from becoming larger than a predetermined level. In the present embodiment, as shown in FIG. 9, the configuration in which two pressure relief mechanisms 400 are provided for one pressure receiving rotary blade 4 is illustrated, but the present invention is not limited to this, and one or three is also possible. It may be the above. Moreover, it is not necessary to provide the pressure relief mechanism 400 with respect to all the pressure receiving rotary blades 4, and you may make it provide only in a part of rotary body unit 1a with which the power generator 1 is provided.

Further, a generator 10 and a gear box 11 are provided on the top surfaces of the first, second, and fourth detour prevention plates 5 from the bottom, and the rotation of the longitudinal rotation shaft 2 is transmitted to the generator 10 via the gear box 11. It is to be transmitted. Note that the other power generator 1 arranged in parallel has the same configuration as described above.

  With such a configuration, it is possible to efficiently generate power using wind power by the two power generation devices 1. In addition, since each power generator 1 is provided with a plurality of generators 10, it is possible to generate power more efficiently. In addition, in FIG. 11, although the case where the two power generation devices 1 were arranged in parallel was illustrated, it is not restricted to this, You may arrange three or more power generation devices 1 in parallel. In addition, the number of detour prevention plates 5 in each power generation device 1 and the number of rotating body units 1a provided between the upper and lower detour prevention plates 5 may be appropriately determined according to the installation environment.

Moreover, as for this power generator 1, the upper part comprises the wind power generator 1A and the lower part comprises the tidal current power generator 1B. That is, in the upper wind power generator 1A, a plurality of (three in FIG. 12) detour prevention plates 5 opposed to each other in the vertical direction are supported by the support columns 6, and these detour prevention plates 5 penetrate vertically. Thus, one longitudinal rotation shaft 2 is provided. In addition, four rotating body units 1a are provided between the two detour prevention plates 5 at the bottom and the center and between the two detour prevention plates 5 at the center and the upper. The upper end of the vertical rotation shaft 2 is supported by a shaft receiver 24, and the lower end is connected to a generator 10 installed at a predetermined height from the sea surface via a gear box 11. In addition, the support | pillar 6 is erected on the concrete foundation installed in the seabed.

  On the other hand, the lower tidal current generator 1B includes a shaft support frame (shaft support) 30 that accommodates the rotary unit 1a and supports the longitudinal rotary shaft 2, and in the example of FIG. Two rotating body units 1a are provided so as to share one longitudinal rotating shaft 2. The vertical rotation shaft 2 passes through the upper portion of the shaft support frame 30 upward, and the generator 10 is connected to the upper end of the vertical rotation shaft 2 via the gear box 11.

It is like that.

  The shaft support frame 30 is supported by the support 6 via the tide level adjusting wave absorbing spring 12. The tide level adjusting wave absorbing spring 12 is movable in the vertical direction along the support column 6 extending in the vertical direction, and the tide power generation device 1B can be moved up and down in accordance with a change in the tide level. Further, the tide level adjusting wave absorbing spring 12 has an elastic body such as a coil spring so that the wave pressure received by the rotating body unit 1a or the shaft support frame 30 can be buffered. Further, a fence 14 is provided in a portion of the support 6 from a predetermined height on the sea surface to the sea floor, and floating substances on the sea surface and foreign matters drifting in the sea are in the rotator unit 1a. It does not hinder its operation by adhering.

Therefore, it is possible to efficiently generate power using both wind force and tidal current. Note that, as in the present embodiment, a plurality of machines are also provided side by side as in the case of the second embodiment (see FIG. 11) for the power generation apparatus 1 of the type having both the wind power generation apparatus 1A and the tidal current power generation apparatus 1B. It may be configured as described above, and the number of rotating body units 1a can also be determined as appropriate according to the installation environment.

FIG. 13 is a plan view showing a configuration of a tidal current power generation device constituting the power generation device 1 according to Embodiment 4, and FIG. 14 is an enlarged side view showing a part of the power generation device 1 of FIG. The power generation device 1 according to the fourth embodiment has a configuration in which a plurality of tidal current power generation devices 1B described in the third embodiment are connected in a plane. More specifically, as shown in FIG. 14, a plurality of piles 8 are erected so as to pierce the seabed so as to be approximately diamond-shaped, and a fence 14 is provided so as to go around the outside. Further, a fence float 25 is attached to the fence 14. In addition, in FIG. 14, the case where twelve piles 8 are erected is illustrated.

  A plurality (eight in FIG. 14) of tidal power generators 1B are provided in the inner region surrounded by the piles 8 arranged in this manner, and between tidal power generators 1B adjacent to each other or tidal power generator 1B. And the pile 8 are connected by a tide level adjusting wave absorbing spring 12. Here, any tidal power generator 1B is equally connected to another adjacent tidal power generator 1B or pile 8 by eight tidal level adjusting wave absorbing springs 12. For example, in the case of the configuration illustrated in FIG. 14, the four tidal power generation devices 1B located at the left and right ends and the upper and lower ends are separated by four tidal level adjustment wave absorbing springs 12 between two adjacent tidal power generation devices 1B. In addition to being connected to each other, three tide level adjusting wave absorbing springs 12 are connected to three neighboring piles 8. The remaining four tidal power generators 1B located between these four machines are connected to six adjacent tidal power generators 1B by six tidal level adjustment wave absorbing springs 12 and two adjacent tidal power generators 1B. Two tide level adjusting wave absorbing springs 12 are connected to the pile 8. Further, one or a plurality of these tidal current power generation apparatuses 1B are appropriately attached with a gutter 21.

  With such a configuration, it is possible to configure the power generation device 1 in which a plurality of tidal current power generation devices 1B are arranged in a plane, and therefore it is possible to efficiently generate power using the tidal current. Moreover, since the fence 14 is arranged around, it can prevent that the operation | movement of the rotary body unit 1a is inhibited by the foreign material in the sea and the sea. In addition, since all the tidal power generation devices 1B are connected to each other by the tidal level adjusting wave absorbing spring 12, the influence of tidal level fluctuations and waves can be buffered, and durability is improved. As shown in FIG. 14, the tide level adjusting wave absorbing spring 12 that connects the tidal power generation device 1 </ b> B and the pile 8 is more specifically connected to a tide level corresponding variable tool 16 that is externally fitted to the pile 8. Yes. Therefore, the shaft support frame 30 and the rotating body unit 1a (that is, the tidal current power generation device 1B) can be moved up and down in accordance with fluctuations in the tide level.

(Embodiment 5)
FIG. 15 is a front view showing the configuration of the power generation device 1 according to the fifth embodiment. In this power generation device 1, the power generation device 1 having the same configuration as that shown in FIG. 1 described in Embodiment 1 is installed on the roof of a high-rise building 19. In addition, in the electric power generating apparatus 1 shown in FIG. 15, although the blade | wing connection rod 27 which connects the upper and lower pressure receiving rotation blade | wings 4 is not illustrated, it cannot be overemphasized that this may be provided similarly to FIG. By installing the power generation device 1 on the rooftop of the high-rise building 19 as described above, it is possible to efficiently generate power by effectively utilizing the rooftop space that tends to be a surplus space and that can obtain large wind power. Moreover, since the power generation place and the power consumption place are located in a short distance by being installed on the roof of a building that uses electric power, it is possible to reduce the transport loss of the generated power.

(Embodiment 6)
FIG. 16 is a front view showing the configuration of the power generation device 1 according to the sixth embodiment. This power generator 1 has a configuration in which a wind power generator 1A is provided in each space 31 and a roof portion of a high-rise building 32 in which the spaces 31 are formed in a matrix in a front view. Each wind power generator 1A has a rectangular frame shape in a front view and accommodates three rotating body units 1a in a shaft support frame 33 that supports the vertical rotating shaft 2, and the shared vertical rotating shaft 2 A generator 10 is connected to the lower end of the generator via a gear box 11. Further, an elevating device 34 is installed on the side of the high-rise building 32 so that an operator can directly maintain the wind power generator 1A of each layer. By installing the wind power generator 1 </ b> A in such a dedicated high-rise building 32 and configuring the power generator 1, power can be generated efficiently. In addition, the space is suitably provided in the side of the wind power generator 1A of each floor of the high-rise building 32, and the upper direction. Of these, the side space can be used as a work space for workers during the maintenance described above. Further, the upper space can be used as an installation space for an air volume adjusting mechanism such as a shutter box 602 described later with reference to FIG.

(Modification)
By the way, the power generation device 1 according to each of the embodiments described above can be separately provided with an air volume adjusting mechanism (flow rate adjusting mechanism) for adjusting the air volume reaching the rotating body unit 1a. For example, a region indicated by a broken line in FIGS. 1 and 2 serves as an entrance 500 through which wind from the outside enters the power generator 1 toward the rotating body unit 1a. Therefore, by providing an air volume adjusting mechanism at the entrance 500, the air flow at the entrance 500 can be limited, and the wind pressure received by the rotating body unit 1a can be adjusted. Of course, the power generation apparatus 1 has a region that becomes the entrance 500 in addition to the region indicated by the broken lines in FIGS. 1 and 2, and therefore, by providing an air volume adjusting mechanism at each entrance 500, each rotary unit 1 a is provided. The wind pressure received from each direction can be adjusted.

  In this way, if the wind pressure received by the rotating body unit 1a can be adjusted, for example, when strong wind is generated as in the case of the arrival of a typhoon, the entrance 500 is completely shut off to reduce the flow rate to zero. The over rotation of the body unit 1a can be prevented. Further, when the entrance 500 is partially blocked, the wind pressure received by the rotating body unit 1a can be adjusted within a desired range of appropriate values, so that power generation can be continued even under strong winds. There is an advantage that you can. Hereinafter, such an air volume adjusting mechanism will be described in detail. Note that the air volume adjusting mechanism described below is applied to the power generation apparatus 1 that is installed on the ground and constitutes a wind power generation apparatus, as shown in FIGS. 1, 11, 12, 15, and 16. However, it is needless to say that the present invention can also be applied to the power generation apparatus 1 when it is installed in water to form a tidal current power generation apparatus as shown in FIGS. 12, 13, and 14.

  FIG. 17 is a schematic side view showing an example of the air volume adjusting mechanism, and shows a cross-sectional view of a device that can be installed at the entrance 500 of FIG. 2 taken along the line FF. Note that “upstream” and “downstream” used in the following description are “upstream” and “downstream” of the entrance 500 with reference to the direction of the wind entering the rotary unit 1a as shown in FIG. ".

  As shown in FIG. 17, the air volume adjusting mechanism 501 includes an outer peripheral blade support 502 extending in the vertical direction, and a plurality of fixed blades 503 are attached to the outer peripheral blade support 502 with a predetermined interval (distance L1). ing. The fixed blade 503 is formed of a rectangular plate-like member, and is fixedly supported on the outer peripheral blade column 502 in a substantially horizontal state so as to be substantially parallel to the ventilation direction. Further, the support position is set near the center position of the dimension of the fixed blade 503 in the ventilation direction (dimension in the width direction).

  In the outer peripheral blade support 502, a variable blade 504 is attached between the fixed blades 503 adjacent in the vertical direction. The variable blade 504 is formed of a rectangular plate-like member similarly to the fixed blade 503, and the width direction dimension L2 is larger than the distance L1 between the fixed blades 503 described above. And it is supported by the outer periphery blade | wing support | pillar 502 in the center position vicinity of the width direction dimension. However, the variable blade 504 is pivotally supported by a pivot 505 provided on the outer peripheral blade support 502, and is rotatable with respect to the outer peripheral blade support 502. That is, the variable blade 504 is moved from a substantially horizontal state (shown by a solid line in FIG. 17) to one end portion (upstream end portion) 504a in the ventilation direction approaching (or contacting) the lower fixed blade 503, The other end portion (downstream end portion) 504b is rotatable between a state (shown by a broken line in FIG. 17) in which the other end portion (downstream end portion) 504b approaches (or abuts) the upper fixed blade. In addition to the above, the upstream end 504a approaches the upper fixed blade 503 (or abuts), and the downstream end 504b approaches the lower fixed blade (or abuts). It may be movable.

  A variable blade connecting rod 506 is connected to an upstream end 504a of a plurality of variable blades 504 arranged vertically. More specifically, the upper end and the lower end of the variable blade connecting rod 506 are pivotally supported by the upstream end portions 504a and 504a of the two variable blades 504 and 504 arranged side by side. Similarly, the upper end and the lower end of the variable blade connecting rod 506 are also pivoted with respect to the other two variable blades 504 and 504 arranged side by side. Furthermore, an actuator 507 formed of a hydraulic cylinder or the like is provided above the uppermost variable blade 504. The variable blade connecting rod 506 is also connected to the output end of the actuator 507 (for example, the lower end of the plunger that moves forward and backward from the hydraulic cylinder) 507a and the upstream end 504a of the uppermost variable blade 504. The upper and lower ends are pivoted.

  Therefore, when the actuator 507 is driven to move the output end 507a up and down, the variable blades 504 pivotally supported via the variable blade connecting rod 506 rotate around the pivot 505 in conjunction with each other. ing. The variable blade connecting rod 506 connected to the upstream end 504 a of the variable blade 504 is provided so as to be located further upstream than the upstream end of the fixed blade 503. Further, the upper and lower portions of the variable blade connecting rod 506 are curved toward the downstream side, and the ends thereof are connected to the variable blade 504. Therefore, the variable blade connecting rod 506 does not interfere with the fixed blade 503.

  On the other hand, similarly to the variable blade connecting rod 506 and the actuator 507 that connect the upstream end 504a of the variable blade 504, the variable blade connecting rod 506 and the actuator 507 that connect the downstream end 504b of the variable blade 504 are provided. (See FIG. 17). Therefore, the variable blade 504 can be reliably rotated by the two actuators 507 even in a strong wind. The actuator 507 can move the output shaft 507a forward and backward, and can stop the output shaft 507a at an arbitrary position (length) and maintain the state. Therefore, by appropriately adjusting the position of the output shaft 507a, the rotation angle (opening degree) of the variable blade 504 can be adjusted from the fully closed state to the fully open state, and the ventilation rate can be adjusted appropriately.

  Here, as schematically shown in the block diagram of FIG. 17, each actuator 507 is connected to a controller 508 provided at an appropriate location of the power generator 1, and the controller 508 includes the uppermost part of the power generator 1 and the like. The anemometer 509 installed in the is connected. The anemometer 509 measures the wind speed around the power generator 1 and transmits the measured value to the controller 508. The controller 508 drives the actuator 507 based on the received measurement value. For example, when the received measurement value is equal to or less than the wind speed of 25 [m / sec], the variable blade 504 is set in a fully open state (horizontal state). On the other hand, when the wind speed exceeds 25 [m / sec], the actuator 507 is driven to incline the variable blade 504 so that the air flow rate is zero or limited. By providing the anemometer 509 and the controller 508 as described above, the variable blade 504 can be automatically rotated according to the wind speed and adjusted to an appropriate ventilation rate.

  In the above description, the air volume adjusting mechanism 501 is provided with the two actuators 507. However, if the variable blade 504 can be appropriately rotated with respect to the assumed wind pressure, one machine may be used. Further, it is possible to adopt a configuration in which only the variable blades 504 are provided in parallel and the fixed blades 503 are omitted. Furthermore, the opening degree of the variable blade 504 may be adjustable by a manual operation when the operator inputs a predetermined operation to the controller 508. In addition, it goes without saying that the configuration of the air volume adjusting mechanism 501 shown in FIG. 17 can be appropriately changed within a range in which the object of adjusting the air flow can be achieved.

  By the way, the air volume adjusting mechanism is not limited to the configuration of FIG. 17 described above. FIG. 18 is a schematic perspective view illustrating another configuration of the air volume adjusting mechanism. The air volume adjusting mechanism 601 shown in FIG. 18 includes a shutter box 602, a shutter plate 603 that can be accommodated in the shutter box 602, and a guide 604 for opening and closing the shutter plate 603.

  Of these, the shutter box 602 has a rectangular parallelepiped shape that is long in the left-right direction, and a slit-like opening (not shown) that communicates with the internal space is formed on the lower surface thereof. The shutter box 602 is provided with a rotation shaft (not shown) having a length substantially the same as the horizontal dimension thereof and connected to the output shaft of the electric motor. On the other hand, the shutter plate 603 has a configuration in which a plurality of strip-shaped plate members 603a that are long in the left-right direction are connected in the vertical direction, and all or some of the plate members 603a have slit-shaped ventilation openings 603b. Is formed. The upper end portion of the shutter plate 603 is connected to a rotation shaft provided inside through the opening of the shutter box 602 described above. Therefore, by driving the electric motor and rotating the rotating shaft in one direction, the shutter plate 603 can be wound around the rotating shaft and accommodated in the shutter box 602, and by rotating in the other direction, The shutter plate 603 can be pulled out from the shutter box 602.

  Further, guides 604 are provided in the vicinity of the left and right ends of the drawn shutter plate 603. The guide 604 includes guide rails 604a disposed on the front and back sides of the shutter plate 603, and guide rollers 604b provided at appropriate positions on the guide rail 604a. The shutter plate 603 is guided by the guide roller 604b from both the front and back sides to move in the winding direction and the drawing direction.

  Also in the case of such an air volume adjustment mechanism 601, the opening / closing amount of the shutter plate 603 is adjusted between the fully opened state where all the shutter plates 603 are wound up and the fully closed state where all the shutter plates 603 are pulled out, thereby reducing the air flow rate. Can be adjusted. Further, since the ventilation hole 603b is formed in the shutter plate 603, power can be generated by the wind that has entered through the ventilation hole 603b even in the fully closed state. Further, since the guide 604 is provided, the shutter plate 603 can be opened and closed relatively smoothly under strong winds. The air volume adjusting mechanism 601 shown in FIG. 18 may be provided with a controller and an anemometer in the same manner as the air volume adjusting mechanism 501 shown in FIG. 17 so that the shutter plate 603 is automatically opened and closed.
