Description

  The present invention relates to a power device using wind that operates by obtaining power from wind, and a blade member used for the power device.

  Examples of the power device that uses wind include a generator that generates electric power, a pump that includes a pump, and pumps water.

  There are various types of such power units, and among them, for example, a vertically arranged rotating shaft (hereinafter, referred to as a vertical rotating shaft) and a perpendicular rotating shaft are attached. There are some which have a horizontal rod and a blade member (wing) attached to the horizontal shaft, and rotate the vertical rotation shaft through the horizontal shaft by receiving wind at the blade member. For example, Patent Documents 1 to 3 disclose such a power unit.

Japanese Patent Laid-Open No. 53-13040 (FIG. 2) Japanese Patent Laid-Open No. 3-202679 (FIGS. 1 to 7 and 11) JP 2002-21706 A (FIGS. 1 and 2)

  For example, it is preferable that the power device using the wind smoothly rotates even with a slight wind having a wind speed of 3.4 M / S or less, referred to as the wind power 2. For this purpose, the most important issue is how to efficiently convert the wind energy into the rotational power of the vertical rotation shaft without losing the wind energy as much as possible.

  However, the conventional technology has a complicated structure and tends to be heavy, and there are many factors that cause the loss of wind energy. Therefore, it has been difficult for the conventional technology to smoothly rotate the vertical rotation shaft with a slight amount of wind.

  For example, Patent Document 1 discloses a vertical rotation shaft (axle in Patent Document 1), a horizontal shaft (blade mounting shaft), a blade member (blade), and a member that suppresses rotation of the blade member (inhibition rod). Is disclosed.

  In the power device described in Patent Document 1, the following factors cause a great loss of wind energy.

  That is, the direction of the plate surface of each blade member is the direction of receiving wind force from the direction of flowing wind force (that is, the horizontal direction, hereinafter referred to as the direction of flowing wind) (that is, the vertical direction, and hereinafter When the direction is changed to a direction of receiving wind), each blade member operates independently of the other blade members, so that each blade member moves suddenly and collides with the restraint rod. At this time, vibration is generated. The vibration affects the operation of each blade member and other members, and hinders their smooth operation. Therefore, a great deal of wind energy is lost.

  In addition, when the direction of the plate surface of each blade member changes from the direction of receiving wind (that is, the vertical direction) to the direction of flowing wind (that is, the horizontal direction), each blade member only follows the flow of the wind, Each blade member operates slowly. Moreover, since each blade member is pulled downward by gravity, if the wind force is weak, each blade member cannot be raised horizontally. In these cases, the blade member acts as a brake.

  Moreover, the apparatus of patent document 1 does not prescribe | regulate the number of the blade members arrange | positioned on the same horizontal surface, The structure which arrange | positions many (4 sheets) blade members on the same horizontal surface is also disclosed. However, in such a configuration, since any of the blade members may be leeward of another blade member, the wing member that has become leeward does not receive wind force. Also in this case, the leeward blade member acts as a brake.

  Further, since the vertical rotation shaft supports the horizontal axis in a cantilever manner, it is necessary to increase the strength of the mechanism that supports the horizontal axis of the vertical rotation shaft. In order to increase the strength of this mechanism, it is necessary to increase the thickness of the mechanism or provide an additional configuration. Therefore, the weight of the mechanism increases, and the smooth rotation of the blade member is hindered.

  In Patent Document 2, a vertical rotation shaft (vertical main shaft in Patent Document 2), a horizontal shaft (lateral shaft), a blade member (rotating blade), and a blade member according to the rotation of the vertical rotation shaft are specified. A power device is disclosed that includes a mechanical mechanism (angle converter) that rotates to an angle and a member (arrow blade) that operates the mechanical mechanism. Further, in Patent Document 3, as in Patent Document 2, a vertical rotation shaft (rotation shaft in Patent Document 3), a horizontal shaft (core bar), a blade member (wind receiving blade), and a vertical rotation shaft. A mechanical mechanism (wing actuating rod, lever, chain, lever fixing frame, rotating plate) that rotates the blade member at a predetermined angle according to the rotation of the blade, and a member (direction rod) that operates the mechanical mechanism; There is disclosed a power plant comprising:

  In such a power device described in Patent Document 2 or 3, the following factors cause a significant loss of wind energy.

  In other words, the device described in Patent Document 2 or 3 is preferably limited in the direction in which the wind is received, and in order to obtain the best efficiency, the direction of the complicated mechanism, that is, the mechanical mechanism of the device is the wind direction. The member which operates a mechanical mechanism (the arrow blade in patent document 2, the direction rod in patent document 3, and the mechanism which supports a mechanical mechanism rotatably) is required so that it may become parallel. For this reason, when the wind direction changes, the blade member and other members do not operate smoothly, the efficiency temporarily decreases, and it takes time to obtain the best efficiency. In addition to the blade members, there are many members that receive wind resistance. Furthermore, the complexity of the structure increases the weight of the mechanism.

  In addition, the device described in Patent Document 2 or 3 does not define the number of blade members arranged on the same horizontal plane, and discloses a configuration in which a large number (four) of blade members are arranged on the same horizontal plane. Yes. However, in such a configuration, since any of the blade members may be leeward of another blade member, the wing member that has become leeward does not receive wind force. Also in this case, the leeward blade member acts as a brake.

  These factors hinder smooth rotation of the blade member. Therefore, a great deal of wind energy is lost.

  Therefore, the devices described in Patent Documents 1 to 3 have a factor of losing wind energy, so even with a slight amount of wind, the vertical rotation shaft does not rotate or rotates awkwardly even if it rotates. . That is, the devices described in Patent Documents 1 to 3 have a problem that it is difficult to smoothly rotate the vertical rotation shaft with a slight wind.

  In addition, the apparatus described in Patent Document 1 also has a secondary problem that noise such as “bang” is generated due to the collision between the blade member and the restraining rod. In addition to such problems, the device described in Patent Document 2 or 3 has a large number of parts and a complicated structure, which increases manufacturing costs, makes installation difficult, and causes failures. There is also a problem.

  The present invention has been made in view of such circumstances. A power device using wind that can reduce the weight and can rotate the vertical rotation shaft even with a small amount of wind, and a suitable power supply for the power device. It is an object to provide a simple blade member.

  In order to solve the above-mentioned problems, it is preferable to devise the configuration of the power device using wind and to devise the configuration of the blade member used for the power device.

  Accordingly, a power device using wind according to the present invention includes a vertically arranged rotatable vertical rotating shaft, a rotatable horizontal rotating shaft orthogonal to the vertical rotating shaft and passing through the vertical rotating shaft, and a vertical A plate-like first and second blade member attached to both sides of the horizontal rotation shaft around the rotation shaft, and a power mechanism that operates according to the rotation of the vertical rotation shaft. The blade members are fixed so that the orientations of the respective plate surfaces are shifted from each other by an angle of 90 degrees in the axial direction of the horizontal rotation shaft, and the vertical direction and the horizontal direction are respectively centered on the horizontal rotation shaft. The rocking mechanism is characterized by swinging in conjunction with each other.

  The first and second blade members of such a power unit operate as follows. That is, first, when there is no load and no wind, the first and second blade members are stopped at an angle of 45 degrees with the plate surface facing downward from the horizontal plane. When the first and second blade members receive wind in this state, one of them acts so as to receive torque generated by the wind (hereinafter referred to as wind force). At this time, the direction of the plate surface of one blade member is a direction to receive wind (that is, the vertical direction in which the wind resistance is maximized), and the direction of the plate surface of the other blade member is a direction of flowing wind (that is, Horizontal direction that minimizes wind resistance). One blade member receives the force of the wind and pushes the horizontal rotation shaft in a predetermined direction, and the horizontal rotation shaft rotates the vertical rotation shaft. Thereafter, the direction of the plate surface of one blade member gradually changes from the direction of receiving wind (ie, the vertical direction) to the direction of flowing wind (ie, the horizontal direction). The direction of the plate surface changes from the direction in which the wind flows (that is, the horizontal direction) to the direction that receives the wind (that is, the vertical direction). When the other blade member receives wind force, the other blade member pushes up one blade member in the horizontal direction, and receives the wind force to push the horizontal rotation shaft in a predetermined direction. Rotate the vertical rotation axis. Thereafter, the direction of the plate surface of the other blade member is changed later from the direction of receiving the wind (ie, the vertical direction) to the direction of flowing the wind (ie, the horizontal direction). The direction of the plate surface changes from the direction in which the wind flows (that is, the horizontal direction) to the direction that receives the wind (that is, the vertical direction). When one blade member receives wind force, this time, one blade member pushes up the other blade member in the horizontal direction, receives the wind force and pushes the horizontal rotation shaft in a predetermined direction, Rotate the vertical rotation axis. Thereafter, the first and second blade members repeat the same operation alternately to rotate the vertical rotation shaft. Such first and second blade members operate in conjunction with each other (that is, each other operates by utilizing the force of wind acting on each other blade member). Therefore, the operation is very smooth with little energy loss. Such operations of the first and second blade members are realized by a horizontal rotation shaft that penetrates the vertical rotation shaft.

  In the power device using wind according to the present invention, the first and second blade members operate in conjunction with each other by the horizontal rotation shaft. Therefore, each blade member works to push up another blade member in the horizontal direction when the direction of the plate surface changes from the direction of flowing wind to the direction of receiving wind, so that its operation is restricted and operates rapidly. There is nothing to do. Conversely, when the direction of the plate surface changes from the direction of receiving wind to the direction of flowing wind, each blade member is pushed up in the horizontal direction by another blade member, so that it reaches the horizontal direction with quick operation. Can do. Further, even if each blade member is in the direction in which the wind flows, the blade members are maintained in the horizontal direction by another blade member, and therefore do not flutter. In this way, the first and second blade members operate so as to complement each other's movement, and thus operate very smoothly. Therefore, the power device using the wind according to the present invention can convert the wind energy to the rotational power of the vertical rotating shaft very efficiently, that is, with almost no loss of the wind energy. Therefore, the vertical rotation axis can be rotated even with a slight wind. In addition, generation of vibration and noise can be suppressed.

  In the power device using wind according to the present invention, the horizontal rotating shaft is passed through the vertical rotating shaft, and the first and second blade members are fixed by changing the phase by 90 degrees on both sides of the horizontal rotating shaft. Therefore, a complicated mechanism for operating the blade member in a supported state and a complicated mechanism for rotating the horizontal rotation shaft are not required. Therefore, it can be configured with a minimum number of parts. Therefore, the structure can be simplified and the weight can be reduced. Further, the manufacturing cost can be reduced, the installation can be facilitated, and the failure can be hardly generated.

  In the power device using wind according to the present invention, the first and second blade members are preferably configured as follows. In other words, when the first and second blade members are the first and second blade members, the first and second blade members are divided into two portions by the horizontal rotation shaft. In addition, the first section member and the second section member are formed so that the magnitude of the force received from the wind is different, and the first section member and the second section member rotate with respect to the rotational moment generated by the gravity of the first and second section members. It is preferable that the weight balance is adjusted so that a load is applied to a smaller moment. Ideally, the first and second blade members can be adjusted by the gravity of the first and second segment members even when the difference in rotational moment generated by the gravity of the first and second segment members is maximum by adjusting the weight balance. It is preferably formed so as to be less than 0.2 times the larger rotational moment. Since the weight balance of the first and second blade members is adjusted so that the rotational moment is close to 0, energy loss is small and the blades rotate very smoothly even with a small amount of wind.

  Further, the power device using wind according to the present invention is arranged in a plurality of stages, and each of the horizontal rotation shafts constituting each stage is at a different position on the axis of the vertical rotation shaft and the vertical rotation shaft. It is preferable that they are arranged so as to be shifted by a predetermined angular interval in the axial circumferential direction. In particular, the predetermined angular interval is preferably a value obtained by dividing 180 degrees by the number of steps or a multiple thereof. When viewed from the vertical rotation axis direction, the first and second blade members are arranged in a plurality of stages in the vertical direction of the vertical rotation axis so that one sheet exists for each predetermined angle. At this time, the first and second blade members are provided in a plural number (specifically, in a multistage manner having 3 to 20 stages or more) with a gap with respect to the vertical rotation axis. Moreover, the first and second blade members are evenly arranged radially about the vertical rotation axis when viewed from above. Such first and second blade members are subjected to a smooth operation because any one of the blade members always receives wind force and there is no other blade member serving as a brake on the same horizontal plane. Make it possible. Therefore, the power device can obtain power with no variation in rotational torque with respect to the vertical rotation shaft, and can realize high efficiency. Ideally, in the first and second blade members, each of the horizontal rotation shafts constituting each stage is arranged in a butterfly shape. As a result, any one of the blade members always receives a wind force, and there is no other blade member serving as a brake on the same horizontal plane. Further, since the step receiving the wind is displaced from the bottom to the top or from the top to the bottom, the force applied to the vertical rotation axis can be dispersed, and the vibration can be reduced. For this reason, the 1st and 2nd blade member enables further smooth operation. As a result, the power device can obtain power without variation in rotational torque with respect to the vertical rotation shaft, and can realize high efficiency.

  The power device using wind according to the present invention includes a restriction mechanism that restricts the rotation of the horizontal rotation shaft to 90 degrees, and the restriction mechanisms are provided on both sides of the horizontal rotation shaft around the vertical rotation shaft. The first and second contact members, and the first and second receiving members respectively provided on the vertical rotation shaft, which can be brought into contact with each of the first and second contact members, are preferable. . As a result, the power plant can reliably ensure the rotation angle of the horizontal rotation shaft.

  In the power device using wind according to the present invention, the first and second blade members are preferably provided with shock absorbers. As a result, the power unit reduces the impact on the first and second blade members, the horizontal rotation shaft, and the vertical rotation shaft, and prevents wear of these members, thereby extending the life of the entire device. Can do.

  The power device using wind according to the present invention is provided so as to protrude from the vertical rotation shaft and comes into contact with the first and second blade members to stop the rotation of the first and second blade members. It is preferable to provide a stopper member. Thereby, the power unit can stop the blade members on both sides at an appropriate angle. Moreover, since each blade member is stopped, a smaller force is required than when the horizontal rotation shaft is stopped.

  Further, in the power device using wind according to the present invention, it is preferable that the vertical rotating shaft is provided with a bearing portion that reduces frictional resistance with the horizontal rotating shaft. Thereby, the horizontal rotating shaft can be rotated with a small frictional resistance by the bearing portion, and the vertical rotating shaft can be rotated in this state.

  Moreover, it is preferable that the power apparatus using the wind which concerns on this invention is equipped with the rotation setting mechanism which sets the rotation direction of a vertical rotating shaft. In particular, the rotation setting mechanism is provided on the protrusion provided on the horizontal rotation shaft and the first and second blade members, and engages with the protrusion to determine the rotation direction of the vertical rotation shaft. It is preferable that it consists of a part. The engaging portion is, for example, a pin inserted into a hole provided in the periphery of the horizontal rotation shaft of the first and second blade members. The holes are provided on the left and right sides of the protrusion, and the pins are inserted into either of the left and right holes depending on the rotation direction of the vertical rotation shaft. Thereby, the power plant can arbitrarily set the rotation direction of the vertical rotation shaft.

  Moreover, it is preferable that the power apparatus using the wind which concerns on this invention is provided in the horizontal rotating shaft, and is equipped with the hydraulic bumper which sets the direction of the plate | board surface of a 1st and 2nd blade | wing member. As a result, the power unit can fix the first and second blade members in the direction of an arbitrary plate surface, and can reduce the impact applied to the first and second blade members.

  Further, the plate-like blade member provided for the power unit according to the present invention has a first section member and a second section member when each of the two sections divided by the horizontal rotation shaft is a first section member and a second section member. The second section member is formed so that the magnitude of the force received from the wind is different, and the load is applied to the smaller rotation moment with respect to the rotation moment generated by the gravity of the first and second section members. It is preferable that the weight balance to be added is adjusted. Ideally, the blade member has a large rotational moment generated by the gravity of the first and second segment members even when the difference between the rotational moments generated by the gravity of the first and second segment members is maximum by adjusting the weight balance. It is preferable that it is formed to be less than 0.2 times the direction. Since the weight balance is adjusted so that the rotational moment approximates zero, such a blade member operates very smoothly with little loss of energy.

  Here, the difference in rotational moment is preferably set by changing the weight per unit area between the first section member and the second section member, and the difference per unit area of the first and second section members. The weight is preferably changed by any of the following methods. That is, the weight per unit area of the first and second segment members is changed by placing a load on either the first or second segment member. Or the weight per unit area of the 1st and 2nd division member is changed by using the raw material from which specific gravity differs with a 1st division member and a 2nd division member. Or the weight per unit area of the 1st and 2nd division member is changed by forming in the thickness from which a 1st division member and a 2nd division member differ. All of these blade members stably stop the first and second blade members in a predetermined state (that is, the angle of the plate surface is 45 degrees downward from the horizontal plane) when there is no load and no wind. In addition, the operation at the start and at the time of rotation can be made smooth.

  Furthermore, the vane member has a position of a load applied when reducing the difference in rotational moment in order to reduce the moment of inertia that increases when reducing the difference in rotational moment generated by the gravity of the first and second section members. Is ideally within 0.1 times the width of the member to which the load is applied from the horizontal rotation axis.

  Moreover, it is preferable that a blade | wing member has an auxiliary wing extended in the direction orthogonal to a horizontal rotating shaft. The auxiliary wings act so as to suppress wind that tends to slip through the outer ends of the first and second blade members. Thus, the power device can improve the wind force applied to the first and second blade members by several percent to several tens percent, and can improve the efficiency of converting wind energy into motive power.

  The blade member is preferably provided with a groove on the plate surface. The groove acts to contain the wind. Thus, the power device can improve the wind force applied to the first and second blade members by several percent to several tens percent, and can improve the efficiency of converting wind energy into motive power.

  In the power device using wind according to the present invention, the first and second blade members are arranged in a vertical direction and a horizontal direction around the horizontal rotation axis by a rotatable horizontal rotation shaft penetrating the vertical rotation shaft. Oscillates in conjunction with each other.

  Such a power unit operates very smoothly because each blade member operates so as to complement each other's movement. Further, there are no blade members or other members that act as brakes. Therefore, the power device using the wind according to the present invention can convert the wind energy to the rotational power of the vertical rotating shaft very efficiently, that is, with almost no loss of the wind energy. Therefore, the vertical rotation axis can be rotated even with a slight wind. In addition, generation of vibration and noise can be suppressed. Further, it can be configured with a minimum number of parts. Therefore, the structure can be simplified and the weight can be reduced. Further, the manufacturing cost can be reduced, the installation can be facilitated, and the failure can be hardly generated.

  In the power device using wind according to the present invention, the first and second blade members are formed such that the magnitude of the force received from the wind is different between the first and second section members. It is preferable that the weight balance is adjusted so that a load is applied to the smaller rotational moment with respect to the rotational moment generated by the gravity of the first and second section members. Ideally, the first and second blade members can be adjusted by the gravity of the first and second segment members even when the difference in rotational moment generated by the gravity of the first and second segment members is maximum by adjusting the weight balance. It is preferably formed so as to be less than 0.2 times the larger rotational moment. Since the weight balance of the first and second blade members is adjusted so that the rotational moment is close to 0, energy loss is small and the blades rotate very smoothly even with a small amount of wind.

  Further, the power device using wind according to the present invention is arranged in a plurality of stages, and each of the horizontal rotation shafts constituting each stage is at a different position on the axis of the vertical rotation shaft and the vertical rotation shaft. It is preferable that they are arranged so as to be shifted by a predetermined angular interval in the axial circumferential direction. As a result, the first and second blade members always receive the force of the wind, and there is no other blade member serving as a brake on the same horizontal plane, so that the smooth operation is achieved. Make it possible. Therefore, the power device can obtain power with no variation in rotational torque with respect to the vertical rotation shaft, and can realize high efficiency. Further, in the first and second blade members, it is ideal that each of the horizontal rotation shafts constituting each stage is arranged in a spiral shape. Thereby, the first and second blade members can easily balance each member at the time of installation and can easily adjust the angle.

  Moreover, it is preferable that the power apparatus using the wind which concerns on this invention is equipped with the control mechanism which controls rotation of a horizontal rotating shaft to 90 degree | times. As a result, the power plant can reliably ensure the rotation angle of the horizontal rotation shaft.

  In the power device using wind according to the present invention, the first and second blade members are preferably provided with shock absorbers. As a result, the power unit reduces the impact on the first and second blade members, the horizontal rotation shaft, and the vertical rotation shaft, and prevents wear of these members, thereby extending the life of the entire device. Can do.

  Further, in the power device using wind according to the present invention, it is preferable that the vertical rotating shaft is provided with a bearing portion that reduces frictional resistance with the horizontal rotating shaft. Thereby, the horizontal rotating shaft can be rotated with a small frictional resistance by the bearing portion, and the vertical rotating shaft can be rotated in this state.

  Moreover, it is preferable that the power apparatus using the wind which concerns on this invention is equipped with the rotation setting mechanism which sets the rotation direction of a vertical rotating shaft. Thereby, the power plant can arbitrarily set the rotation direction of the vertical rotation shaft.

  Moreover, it is preferable that the power apparatus using the wind which concerns on this invention is provided in the horizontal rotating shaft, and is equipped with the hydraulic bumper which sets the direction of the plate | board surface of a 1st and 2nd blade | wing member. As a result, the power unit can fix the first and second blade members in the direction of an arbitrary plate surface, and can reduce the impact applied to the first and second blade members.

  In addition, the plate-like blade member provided for the power device according to the present invention is formed so that the magnitude of the force received from the wind is different between the first partition member and the second partition member. It is preferable that the weight balance is adjusted so that a load is applied to the smaller rotational moment with respect to the rotational moment generated by the gravity of the two-section member. Ideally, the first and second blade members can be adjusted by the gravity of the first and second segment members even when the difference in rotational moment generated by the gravity of the first and second segment members is maximum by adjusting the weight balance. It is preferably formed so as to be less than 0.2 times the larger rotational moment. Such a blade member has a weight balance adjusted so that the rotational moment approximates zero, so that there is little energy loss, and the blade member rotates very smoothly even with a small amount of wind.

  The difference in rotational moment between the blade members is preferably set by changing the weight per unit area between the first segment member and the second segment member, and the unit areas of the first and second segment members. It is preferable that the hit weight is changed by any of the following methods. That is, the weight per unit area of the first and second segment members is changed by placing a load on either the first or second segment member. Or the weight per unit area of the 1st and 2nd division member is changed by using the raw material from which specific gravity differs with a 1st division member and a 2nd division member. Or the weight per unit area of the 1st and 2nd division member is changed by forming in the thickness from which a 1st division member and a 2nd division member differ. All of these blade members stably stop the first and second blade members in a predetermined state (that is, the angle of the plate surface is 45 degrees downward from the horizontal plane) when there is no load and no wind. In addition, the operation at the start and at the time of rotation can be made smooth.

  In addition, the blade member has a position of a load to be applied when reducing the difference in rotational moment in order to reduce the moment of inertia that is increased when reducing the difference in rotational moment generated by the gravity of the first and second section members.

  Embodiments of the present invention will be described below with reference to the drawings. Each figure is only shown schematically to the extent that the present invention can be understood. Therefore, the present invention is not limited to the illustrated example. Moreover, in each figure, about the common element and the same element, the same code | symbol is attached | subjected and those overlapping description is abbreviate | omitted.

<Embodiment>
(Configuration of the entire power unit using wind)
FIG. 1 is a front view of a power device using wind according to an embodiment of the present invention, and FIG. 2 is a partially omitted top view of the device.

  As shown in FIG. 1, a power device 10 using wind according to an embodiment of the present invention has a vertically-rotating vertical rotating shaft 12 arranged vertically and a gap in the vertical direction on the vertical rotating shaft 12. The horizontal rotation shafts 16 to 18 that are arranged at right angles and cross the perpendicular rotation shaft 12 and pass through the vertical rotation shaft 12, and plates that are attached to both sides of the horizontal rotation shafts 16 to 18 around the vertical rotation shaft 12. First and second blade members 19 to 24 and a generator 29 as a power mechanism that operates according to the rotation of the vertical rotation shaft 12.

  The first and second blade members 19 to 24 are fixed such that the directions of the plate surfaces are shifted from each other by 90 degrees in the axial circumferential direction of the horizontal rotation shafts 16 to 18. The first and second blade members 19 to 24 are stopped at an angle of 45 degrees downward from the horizontal plane when there is no load and no wind. With the shafts 16 to 18 as the center, it swings in conjunction with each other between the vertical direction and the horizontal direction.

  In the example shown in FIG. 1, the vertical rotation shaft 12 is attached to the base 11 on the lower end side, but the position where the vertical rotation shaft 12 is attached is not limited thereto. For example, the upper end side or both the upper end and the lower end may be attached to the base 11.

  Moreover, in the example shown in FIG. 1, the bearing parts 13-15 are provided between the vertical rotating shaft 12 and the horizontal rotating shafts 16-18. Thereby, the frictional resistance between the vertical rotating shaft 12 and the horizontal rotating shafts 16 to 18 is reduced.

  In the example shown in FIG. 1, three sets of the first and second blade members are arranged in three stages, but the number of sets of the first and second blade members is not limited to this, There may be one set or a plurality of sets including three. However, as will be described below, the first and second blade members are more efficient when the number of sets is more than one set.

  That is, for example, as shown in FIG. 2, when the number of sets is a plurality of sets, the first and second blade members are evenly arranged by changing the phase of each set by a predetermined angle when viewed from above. The FIG. 2 shows a state where the power unit 10 shown in FIG. 1 is rotated 240 degrees counterclockwise. Here, the predetermined angle is an angle obtained by dividing 180 degrees by the number of sets of the first and second blade members (that is, the number of steps) (or the first and second blade members overlap with each other more than twice. If it is, it is a multiple (2 times, 3 times,...)). For example, the number of first and second blade members is three (that is, the number of steps is three), and the first and second blade members are not overlapped (that is, are arranged in a single layer). The predetermined angle is 60 degrees as shown in FIG.

  Such 1st and 2nd blade | wing members 19-24 can obtain the output characteristic shown in FIG. 3, for example. FIG. 3 shows the output characteristics of any one of the first and second blade members 19 to 24, and the other output characteristic is obtained by shifting the phase of the output characteristics shown in FIG. 3 by 180 degrees. . Here, since the drawing becomes unclear, the other output characteristic is omitted. FIG. 3A shows the output characteristics of one blade member. When the rotation angle of the vertical rotation shaft 12 is 90 degrees, the output state is vertical, and the rotation angle of the vertical rotation shaft 12 is 270 degrees. The characteristic of the blade member which becomes a horizontal state at the time is shown. FIG. 3B shows output characteristics of a plurality of blade members (here, any one of the first and second blade members 19 to 24).

  As shown in FIG. 3A, the blade member can output the maximum stress in a state where the orientation of the plate surface is vertical, and the stress attenuated as it goes from the vertical state to the horizontal state. Is output. And in the state where the direction of a board surface is horizontal, it receives wind resistance, and comes to output a negative stress, and acts as a brake. Therefore, when the power device 10 has one blade member, the output characteristics vary as shown in FIG. That is, the maximum stress can be output only when the rotation angle of the vertical rotation shaft 12 is 90 degrees, 450 degrees,. On the other hand, in the case where there are a plurality of blade members, the power unit 10 receives the wind force more evenly because one of the blade members receives the wind force. Therefore, as shown in FIG. 3B, the power plant 10 outputs a flat output characteristic, that is, a maximum stress or a stress close to the value regardless of the rotation angle of the vertical rotation shaft 12. Characteristics can be obtained, and the vertical rotation shaft 12 can be smoothly rotated.

  Therefore, a plurality of blade members are more efficient than one, and similarly, a plurality of pairs of first and second blade members are more efficient than one set.

  By the way, it is preferable to arrange | position a blade | wing member symmetrically 180 degree | times centering | focusing on the vertical rotating shaft 12 by making two sheets into 1 set by the following points.

  For example, when there is only one blade member, the vertical rotating shaft 12 supports the blade member in a cantilever manner. On the other hand, when the blade member is a set of two, the vertical rotating shaft 12 supports the blade member in a doubly supported manner. The rotation moment about the vertical rotation shaft 12 is different between the case where the vertical rotation shaft 12 is supported in a cantilever manner and the case where the vertical rotation shaft 12 is supported in a both-end support manner, and the both-end support shape is smaller than the cantilever shape. Therefore, in this respect, it is preferable that the blade members are arranged in a symmetrical manner by 180 degrees about the vertical rotation shaft 12 as a set of two sheets.

  Further, when the first blade members 19, 21, 23 and the second blade members 20, 22, 24 are arranged at a position 180 degrees symmetrical about the vertical rotation axis 12, on the same horizontal plane, There will be only one each. Therefore, the first and second blade members 19 to 24 do not become leeward of other blade members and do not act as a brake. Therefore, the power plant 10 can smoothly operate the first and second blade members 19 to 24, and as a result, the rotation efficiency of the vertical rotating shaft 12 can be improved. For this reason, it is preferable that the blade members are arranged in a symmetrical manner by 180 degrees with the vertical rotating shaft 12 as the center, as a pair of blade members.

  In the example shown in FIG. 1, the first and second blade members 19 to 24 are arranged in a spiral shape, but the rotational efficiency of the vertical rotating shaft 12 is the first and second blade members 19 to 19. As long as 24 is evenly arranged at a predetermined angle, it is the same whether it is spiral or not. However, since the first and second blade members 19 to 24 are installed one by one from the bottom, considering the ease of balancing the members and the ease of adjusting the angle during installation, the butterfly It is preferable to arrange in a spiral.

  Hereinafter, the configuration of the power plant 10 will be described in detail.

  The base 11 has a frame member 25 that is anchored to a foundation (not shown). Bearings 26 and 27 that handle radial and thrust loads are fixed to the frame member 25, and the vertical rotary shaft 12 is attached to the bearings 26 and 27. It is mounted in the vertical direction. The base 11 has a built-in generator 29 as a power mechanism fixed to the frame member 25.

  A part of the vertical rotating shaft 12 is provided with a pulley 28, and the pulley 28 is connected to a pulley 30 provided on an input shaft of a generator 29 by a belt 31. As a result, the input shaft of the generator 29 is rotated by the rotation of the vertical rotating shaft 12 to generate electric power.

  The vertical rotary shaft 12 is provided with bearing portions 13 to 15 with a gap larger than the height h of each of the first and second blade members 19 to 24. As shown in FIG. 4 or 5, the bearing portion 13 (same for 14 and 15) is provided with boss portions 32 and 33 on both sides and an insertion hole 34 penetrating the vertical rotating shaft 12 inside. ing. Both sides of the insertion hole 34 are expanded in diameter, and bushes 35 and 36 that are examples of bearings are provided. 4 is an enlarged front view of a portion P in FIG. 1, and FIG. 5 is an enlarged side view of the portion P in FIG. The horizontal rotation shaft 16 (same for 17 and 18) passes through the insertion hole 34. The horizontal rotary shaft 16 (same for 17 and 18) has a main shaft portion 37 penetrating the central insertion hole 34 and projecting shaft portions 38 and 39 provided on both sides thereof, which are connected fittings 40 and 41. It is fixed by. The horizontal rotating shaft 16 rotates with a small frictional resistance by the bearing portion 13.

  In this embodiment, the bearing portion 13 (same for 14 and 15) is provided with flat bushes 42 and 43 for receiving a thrust load at both ends. On the other hand, ring metal objects 44 and 45 are fixed to the main shaft portion 37 of the horizontal rotating shaft 16 (same for 17 and 18) in contact with the flat bushes 42 and 43. The ring hardwares 44 and 45 prevent the lateral movement of the main shaft portion 37 and receive a thrust load generated in the main shaft portion 37.

  The connecting fitting 40 (or 41) for fixing the main shaft portion 37 and the protruding shaft portion 38 (or 39) of the horizontal rotating shaft 16 (same for 17 and 18) is provided with female screws having different diameters from both sides. A male screw formed at one end (or the other end) of the main shaft portion 37 and a male screw provided at the inner end portion of the protruding shaft portion 38 (or 39) are firmly screwed into the female screw.

  The first and second blade members 19 and 20 are fixed to the projecting shaft portions 39 and 38 of the horizontal rotating shaft 16 so as to be shifted from each other by an angle of 90 degrees around the horizontal rotating shaft 16. The first and second blade members 19 and 20 are made of plastic, wood, or metal plate.

  In addition, the horizontal rotation shaft 16 is provided with a mechanism (see FIGS. 4 and 5) that regulates the rotation angle of the horizontal rotation shaft 16 within a range of substantially 90 degrees. That is, the horizontal rotating shaft 16 is provided with first and second metal fittings (an example of an abutting member) 46 and 47 on both sides with the bearing portion 13 at the center. 1st and 2nd receiving metal objects (an example of a receiving member) 48 and 49 which can contact | abut to the 1st and 2nd metal fittings 46 and 47, respectively are provided. Thereby, the horizontal rotating shaft 16 is substantially rotated only within a range of 90 degrees.

  Specifically, as shown in FIGS. 4 and 5, in the horizontal rotating shaft 16, a first metal fitting 46 is provided on one connecting metal fitting 40 on the horizontal rotating shaft 16, and the other connecting hardware 41. In addition, a second metal fitting 47 is provided. The first and second metal fittings 46 and 47 are screwed into substantially L-shaped plate members 50 and 51, application bolts 52 and 53 provided at the ends thereof, and application bolts 52 and 53. And a locking nut.

  On the other hand, the first and second receiving metal objects 48 and 49 provided on both sides of the bearing portion 13 include rectangular plate materials 54 and 55 and receiving bolts 56 and 57 that are screwed to the rectangular plate materials 54 and 55. A locking nut is screwed onto the bolts 56 and 57.

  In this embodiment, the first and second metal fittings 46 and 47 and the first and second metal receiving objects 48 and 49 include the application bolts 52 and 53 and the receiving bolts 56 and 57, respectively. Although the stop angle of the direction of the plate surface of the two blade members 19 and 20 can be finely adjusted, it is not always necessary to be able to finely adjust, and each may be fixed (in this case) The first and second metal fittings 46 and 47 and the first and second metal fittings 48 and 49 are preferably arranged in the bearing portion 13).

  The bearing portions 14 and 15 of the other horizontal rotary shafts 17 and 18 are also provided with a mechanism for restricting the rotation angle of the horizontal rotary shafts 17 and 18 within a range of substantially 90 degrees, like the horizontal rotary shaft 16. ing.

  In the example shown in FIG. 2, three sets of the first and second blade members are arranged in three stages so that three horizontal rotation shafts are inevitably shown. The number of axes is not limited to this, and there may be one or a plurality of axes including three. When there are a plurality of horizontal rotation shafts, it is preferable to provide a gap in the vertical direction in order to prevent interference between the blade members.

  The 1st and 2nd blade | wing members 19-24 of the power plant 10 using the wind comprised as mentioned above operate | move as follows.

  That is, when there is no load and no wind, the first and second blade members 19 to 24 are stopped at an angle of 45 degrees with the plate surface facing downward from the horizontal plane. When the first and second blade members 19 to 24 receive wind in this state, one of them acts so as to receive wind force. For example, it is assumed that the first and second blade members 19 to 24 are in the blade positions as shown in FIG. At this time, the orientation of the plate surfaces of the first blade members 19, 21, 23 is a direction to receive the wind W (that is, a vertical direction in which the resistance of the wind W is maximized), and the second blade members 20, 22, The direction of the plate surface 24 is the direction in which the wind W flows (that is, the horizontal direction in which the resistance of the wind W is minimized). The first blade members 19, 21, and 23 receive the force of the wind W and push the horizontal rotation shafts 16 to 18 in a predetermined direction (here, the counterclockwise direction), so that the horizontal rotation shafts 16 to 18 are pushed. Rotates the vertical axis of rotation 12.

  Thereafter, when the first blade member 23 reaches the leeward position R and becomes parallel to the direction in which the wind W flows, the direction of the plate surface of the first blade member 23 is the direction in which the wind W is received (that is, the vertical direction). Gradually changes in the direction in which the wind W flows (ie, the horizontal direction), and in conjunction with this, the direction of the plate surface of the second blade member 24 changes the direction of the wind W from the direction in which the wind W flows (ie, in the horizontal direction). It changes in the receiving direction (ie, the vertical direction). Then, when the second blade member 24 receives the force of the wind W, the second blade member 24 pushes up the first blade member 23 in the horizontal direction and receives the force of the wind W to rotate horizontally. The shaft 18 is pushed in a predetermined direction, and the vertical rotation shaft 12 is rotated. At this time, the blade members 19 and 21 also receive the force of the wind W and push the horizontal rotary shafts 16 and 17 in a predetermined direction to rotate the vertical rotary shaft 12. Thereafter, when the next first blade member 21 reaches the leeward position R and becomes parallel to the direction in which the wind W flows, the next first blade member 21, the second blade member 22, the horizontal rotary shaft 17, The vertical rotation shaft 12 operates in the same manner. Further, after this, when the next first blade member 19 reaches the leeward position R and becomes parallel to the direction in which the wind W flows, the next first blade member 19, second blade member 20, horizontal The rotating shaft 16 and the vertical rotating shaft 12 operate similarly.

  Thereafter, the first and second blade members 19 to 24 are in a half-rotated state from the state shown in FIG. At this time, the orientation of the plate surfaces of the second blade members 20, 22, 24 is a direction to receive the wind W (that is, the vertical direction), and the orientation of the plate surfaces of the first blade members 19, 21, 23 is the wind W In the direction of flowing (that is, the horizontal direction). The second blade members 20, 22, 24 receive the force of the wind W and push the horizontal rotation shafts 16 to 18 in a predetermined direction, and the horizontal rotation shafts 16 to 18 rotate the vertical rotation shaft 12.

  Thereafter, when the second blade member 24 reaches the leeward position R and becomes parallel to the direction in which the wind W flows, the direction of the plate surface of the second blade member 24 is the direction in which the wind W is received (that is, the vertical direction). Gradually changes in the direction in which the wind W flows (ie, in the horizontal direction), and in conjunction with this, the direction of the plate surface of the first blade member 23 changes from the direction in which the wind W flows (ie, in the horizontal direction). It changes in the receiving direction (ie, the vertical direction). Then, when the first blade member 23 receives the force of the wind W, the first blade member 23 pushes up the second blade member 24 in the horizontal direction and receives the force of the wind W to rotate horizontally. The shaft 18 is pushed in a predetermined direction, and the vertical rotation shaft 12 is rotated. At this time, the second blade members 20 and 22 also receive the force of the wind W and push the horizontal rotary shafts 16 and 17 in a predetermined direction to rotate the vertical rotary shaft 12. Thereafter, when the next second blade member 22 reaches the leeward position R and becomes parallel to the direction in which the wind W flows, the next second blade member 22, the first blade member 21, the horizontal rotating shaft 17, The vertical rotation shaft 12 operates in the same manner. Furthermore, after this, when the next second blade member 20 reaches the leeward position R and becomes parallel to the direction in which the wind W flows, the next second blade member 20, the first blade member 19, and the horizontal The rotating shaft 16 and the vertical rotating shaft 12 operate similarly.

  Thereafter, the first and second blade members 19 to 24 rotate the vertical rotating shaft 12 by repeating the same operation alternately. Such operations of the first and second blade members 19 to 24 are realized by the horizontal rotation shafts 16 to 18 penetrating the vertical rotation shaft 12. And, since the first blade members 19, 21, 23 and the second blade members 20, 22, 24 are performed in conjunction with each other (that is, using the movement of each other), it is very smooth and There is little energy loss.

  In the experiment, in the power device 10 using wind according to this embodiment, the rotation speed of the vertical rotation shaft 12 was 10 to 120 rpm, and the oscillation cycle of the horizontal rotation shafts 16 to 18 was 10 to 120 times / minute. However, the present invention is not limited to this.

  By the way, the aforementioned angle restricting mechanism (see FIGS. 4 and 5) operates as follows as the power unit 10 operates.

  4 and 5, the direction of the plate surface of the first blade member 19 is a vertical direction, and the direction of the plate surface of the second blade member 20 is a horizontal direction. At this time, the second metal fitting 47 abuts against the second metal receiving object 49 and regulates the orientation of the plate surfaces of the first and second blade members 19 and 20.

  In this state, the first blade member 19 receives the force of the wind and pushes the horizontal rotation shaft 16 in a predetermined rotation direction (here, a counterclockwise direction). When the horizontal rotating shaft 16 exceeds the leeward position R shown in FIG. 2, the first blade member 19 is exposed to the wind W from the back side. Thereby, the 1st blade | wing member 19 starts rotation in the arrow Q direction shown in FIG. This rotation is transmitted to the second blade member 20 through the horizontal rotation shaft 16. Thereby, the orientation of the plate surface of the second blade member 20 on the windward side changes from the horizontal direction to the vertical direction. Then, the second blade member 20 receives the force of the wind W. As a result, the second blade member 20 now acts to push up the first blade member 19 in the horizontal direction. At this time, the first metal fitting 46 comes into contact with the first metal receiving object 48 and regulates the orientation of the plate surfaces of the first and second blade members 19 and 20. Such an operation is similarly performed for the first blade members 21 and 23 and the second blade members 22 and 24 provided on the lower horizontal rotary shafts 17 and 18.

(Configuration of the blade member)
FIG. 6 shows the configuration of the blade member 19. The other blade members 20 to 24 have the same configuration.

  In the example shown in FIG. 6, the blade member 19 is a single substance and is formed in a rectangular shape having a uniform thickness in each portion, and is fixed to the horizontal rotating shaft 16 at an intermediate portion instead of an end portion. Has been. Moreover, the blade member 19 is eccentrically fixed to the horizontal rotating shaft 16 and, for example, a load 103 is disposed so that the operation is stable.

  In the example shown in FIG. 6, the blade member 19 is eccentrically fixed to the horizontal rotating shaft 16, but this is a portion of the blade member 19 that is divided into two parts around the horizontal rotating shaft 16. This is because the magnitude of the force received from the wind is different (one is called the first section member and the other is the second section member). When the blade member 19 is made of a single substance and is a rectangle having a uniform thickness at each portion, the force received from the wind is the same for the first section member and the second section member. Therefore, the blade member 19 is eccentrically fixed to the horizontal rotating shaft 16. However, the force received from the wind is such that the blade member 19 is formed of a different material in the first section member and the second section member, has a different thickness in each part, or has a special shape. It differs between the first segment member and the second segment member. Therefore, in such a case, the blade member 19 may be fixed to the horizontal rotating shaft 16 without being eccentric.

  In the example shown in FIG. 6, the blade member 19 is eccentrically fixed to the horizontal rotation shaft 16. Therefore, the blade member 19 is formed with a portion having a larger area (hereinafter referred to as a large area) 101 and a portion having a smaller area (hereinafter referred to as a small area) 102. Hereinafter, a large area portion may be referred to as a long portion. Moreover, a small area part may be called a short part.

A rotational moment M ₁ generated by gravity about the horizontal rotation axis 16 is applied to the center of gravity of the large area 101. In addition, a rotational moment M ₂ generated by gravity is applied to the center of gravity of the small-area portion 102 in the direction opposite to the rotational moment M ₁ around the horizontal rotational axis 16. Since the rotational moment M ₂ is smaller than the rotational moment M _1, a load for stabilizing the operation of the large area portion 101 is applied to the small area portion 102.

  Therefore, in the example illustrated in FIG. 6, the load 103 is disposed in the portion 102 having a small area. In the example shown in FIG. 6, the load 103 is a material having a specific gravity heavier than the material constituting the blade members 19 to 24, and the load 103 is embedded in the portion 102 having a small area. The load 103 may be attached to the outside of the blade member 19 instead of being embedded in the blade member 19. In this case, the load 103 need not be a material having a higher specific gravity than the material constituting the blade member 19 and may be a material having the same specific gravity or a light material. Moreover, the load 103 is not limited to the shape shown in FIG. 6, and can be an arbitrary shape. Therefore, for example, the load 103 may be formed of the same material and the same shape as the small area portion 102 and attached to the small area portion 102.

  As described above, in the example shown in FIG. 6, the weight balance is adjusted with respect to the rotational moment. However, various points need to be taken into account when adjusting the weight balance. Therefore, the adjustment of the weight balance will be described below.

(Weight balance adjustment)
First, the outline of the adjustment of the weight balance will be described.

  The first and second blade members 19 to 24 change the direction of the plate surface using wind energy. At this time, if the first and second blade members 19 to 24 consume a large amount of wind energy, the efficiency of converting the wind energy into rotational power decreases. Therefore, it is preferable that the first and second blade members 19 to 24 consume as little wind energy as possible when changing the orientation of the plate surface. That is, it is preferable to minimize the energy of wind consumed when the first and second blade members 19 to 24 change the orientation of the plate surface.

  The amount related to the energy of the wind consumed when the first and second blade members 19 to 24 change the direction of the plate surface is the rotation moment generated by the gravity around the horizontal rotation axes 16 to 18 and the first. And the moment of inertia of the second blade members 19 to 24.

  Here, the rotational moment generated by gravity around the horizontal rotation axes 16 to 18 is preferably as small as possible (preferably, 0 or a value approximated to 0). Therefore, for example, the load 103 is arranged in the small area portion 102 so that the rotational moment becomes as small as possible. Thereby, the weight balance of the first and second blade members 19 to 24 is adjusted. In that case, it is preferable to arrange | position the load 103 in the place as close as possible to the horizontal rotating shafts 16-18 for the following reasons.

  That is, for example, the 1st and 2nd blade members 19-24 shall be arrange | positioned at the edge part of the horizontal rotating shafts 16-18. In this case, the rotational moment of the first and second blade members 19 to 24 becomes large, and much of the wind energy is consumed for rotating the first and second blade members 19 to 24. Therefore, the rotation efficiency of the vertical rotating shaft 12 is reduced.

  Therefore, in order to reduce the rotational moment of the first and second blade members 19 to 24 as much as possible, the horizontal rotation shafts 16 to 18 are preferably arranged in the center of the first and second blade members 19 to 24. .

  However, in this case, the rotational moment due to gravity on the first and second blade members 19 to 24 divided into two parts by the horizontal rotation shafts 16 to 18, that is, the first and second division members. Are the same. Therefore, the first and second blade members 19 to 24 do not stop at an angle of 45 degrees downward from the horizontal plane at no load and no wind, and the operation becomes unstable at the start of rotation. Moreover, since the area of the 1st division member and the 2nd division member becomes the same, the force of the wind concerning a 1st division member and a 2nd division member becomes the same. For this reason, the first and second blade members 19 to 24 cannot rotate stably because the rotation direction around the horizontal rotation shafts 16 to 18 is not determined. As a result, the rotation efficiency of the vertical rotation shaft 12 is reduced.

  Therefore, the first partition member and the second partition member have different areas, and the wind force applied to the first partition member and the second partition member is made different. Accordingly, the first and second blade members 19 to 24 rotate in a predetermined direction around the horizontal rotation shafts 16 to 18.

  However, at this time, the weight of the first section member and the weight of the second section member, the distance from the horizontal rotation shafts 16 to 18 of the first section member to the center of gravity, and the horizontal rotation shafts 16 to 18 of the second section member. The distance to the center of gravity will be different. For this reason, the first and second blade members 19 to 24 generate different rotational moments between the first segment member and the second segment member.

  Therefore, in order to make the rotation moment of the first section member and the rotation moment of the second section member the same, a load is applied to the one having the smaller rotation moment, and the weight balance of the first and second blade members 19 to 24 is increased. Adjust. For example, the load 103 is arranged on a part or all of the smaller rotational moment. Thereby, the rotational moment of the first and second blade members 19 to 24 is made as small as possible. In this way, the first and second blade members 19 to 24, whose weight balance is adjusted with respect to the rotational moment, rotate smoothly around the horizontal rotation shafts 16 to 18.

  By the way, by adjusting the weight balance with respect to such a rotational moment, either the first section member or the second section member becomes heavy. Therefore, the first and second blade members 19 to 24 increase the moment of inertia. The moment of inertia is proportional to the square of the distance from the center of rotation of the center of gravity, whereas the moment of inertia is proportional to the distance from the center of rotation of the center of gravity. Therefore, in order to make the increasing moment of inertia as small as possible, the distance between the position where the load is applied and the horizontal rotation shafts 16 to 18 is made as small as possible (preferably, a value approximated to 0 larger than 0). Thereby, the weight balance with respect to the moment of inertia of the first and second blade members 19 to 24 is adjusted.

  In this way, the first and second blade members 19 to 24, in which the weight balance with respect to the rotational moment and the weight balance with respect to the inertia moment are adjusted, rotate in a predetermined direction around the horizontal rotation shafts 16 to 18. Rotate more smoothly around the horizontal rotation shafts 16 to 18 without consuming almost any wind energy. As a result, the rotation efficiency of the vertical rotation shaft 12 is improved.

(Formulas related to weight balance adjustment)
Next, adjustment of the weight balance will be described in detail using mathematical expressions.

  In the power unit 10, the rotational moment I about the vertical rotation shaft 12 is different between the case where the vertical rotation shaft 12 supports the blade member in a cantilevered manner and the case where the blade member is supported in a double-supported manner. That is, as shown in FIG. 7 (a), when the base (end) of each of the horizontal rotation shafts 16 to 18 is used as a fulcrum, and as shown in FIG. 7 (b), the horizontal rotation shafts 16 to 18 of The arithmetic expression for calculating the rotational moment I differs depending on the case where each intermediate portion is used as a fulcrum. In the former case, the arithmetic expression for calculating the rotational moment I is the following expression (1). In the latter case, the arithmetic expression for calculating the rotational moment I is the following expression (2). FIG. 7 is a diagram showing the position of the fulcrum of the horizontal rotation shaft. In FIG. 7, the total length of the horizontal rotation shafts 16 to 18 is L, and the weight of the entire horizontal rotation shafts 16 to 18 (including the first and second blade members 19 to 24) is ω.

I = 1/2 × L × ω (1)
I = (1/4 × L × ω) one (1/4 × L × ω) = 0 (2)
As is clear from the comparison between the formula (1) and the formula (2), the rotational moment I is intermediate between the horizontal rotation shafts 16 to 18 than when the base (end) of the horizontal rotation shafts 16 to 18 is used as a fulcrum. The case where the part is used as a fulcrum can be made smaller. In particular, the rotation moment I is minimized when the center of the horizontal rotation shafts 16 to 18 is a fulcrum as shown in FIG. In this case, the horizontal rotation shafts 16 to 18 rotate smoothly around the vertical rotation shaft 12 as shown in FIG. Therefore, the configuration shown in FIG. 8 is preferable as the configuration of the power unit 10. 8 is a diagram showing the position of the fulcrum of the horizontal rotation shaft, FIG. 8 (a) shows the position of the fulcrum of the horizontal rotation shafts 16 to 18, and FIG. 8 (b) is the horizontal rotation. The operation | movement of the axes | shafts 16-18 is shown.

  The first and second blade members 19 to 24 of the power unit 10 with the center of the horizontal rotating shafts 16 to 18 as fulcrums operate as shown in FIG. 9 or FIG. That is, if it rotates in the clockwise direction, it operates as shown in FIG. 9, and if it rotates in the counterclockwise direction, it operates as shown in FIG. FIG. 9 is a diagram showing the operation of the blade member, and FIG. 9A shows the configuration of the pair of first and second blade members 19 to 24 when viewed from above. FIG. 9B shows a configuration of the pair of first and second blade members 19 to 24 when viewed from the direction of the arrow View in FIG. 9A, and FIG. FIG. 9A and FIG. 9B show a state in which the pair of first and second blade members 19 to 24 rotated 45 degrees by receiving the wind W. Moreover, FIG. 10 is a figure which shows operation | movement of a blade | wing member similarly to FIG. 9, FIG.10 (a) is a pair of 1st and 2nd blade | wing members 19-24 when it sees from the top. FIG. 10B shows the configuration of the pair of first and second blade members 19 to 24 when viewed from the arrow View direction of FIG. FIG. 10C shows a state in which the pair of first and second blade members 19 to 24 shown in FIGS. 10A and 10B are rotated 45 degrees by receiving the wind W. Yes.

  In order to minimize the energy of the wind consumed when the first and second blade members 19 to 24 change the orientation of the plate surface, rotation by gravity applied to the first and second blade members 19 to 24 is performed. Moment (hereinafter simply referred to as rotational moment) M and inertia moment (hereinafter simply referred to as inertia moment) N of first and second blade members 19 to 24 may be minimized.

  As described above, in order to minimize the wind energy, first, the rotational moment M generated by the gravity of the first and second blade members 19 to 24 is made as small as possible. Hereinafter, the rotational moment M will be described in detail.

(Rotational moment)
The first and second blade members 19 to 24 need to be formed so that the force received from the wind is different between the first segment member and the second segment member. Because, when the same force is applied from the wind to the first segment member and the second segment member, the first and second blade members 19 to 24 are not determined in the rotating direction, and operate in the clockwise direction and counterclockwise. This is because the operation in the direction is alternately repeated, and the horizontal rotation shafts 16 to 18 cannot be sufficiently rotated. For example, in the case where the first and second blade members 19 to 24 are formed so as to receive the same force from the wind by the first and second partition members, such a power unit 10 is used for wind power generation or the like. Even if it is used, it will not be able to generate enough dragons. Also, even if such a power unit 10 is configured in a multistage manner, the horizontal rotary shafts 16 to 18 do not rotate, or even if they rotate, the horizontal rotary shafts 16 to 18 are mixed in forward and reverse directions. It will rotate in the direction and acts to cancel the rotational power. Therefore, the efficiency of converting wind energy into the rotational power of the vertical rotary shaft 12 is significantly reduced. Therefore, it is necessary to form the first and second blade members 19 to 24 so that the force received from the wind is different between the first segment member and the second segment member.

  Therefore, the position of the fulcrum of the first and second blade members 19 to 24 is not the center but a position deviated from the center as shown in FIG. 11 or FIG. In addition, FIG. 11 is a figure which shows the position of a fulcrum, FIG.11 (a) has shown the structure of the 1st and 2nd blade | wing members 19-24 in a stop state, FIG.11 (b) The structure of the 1st and 2nd blade | wing member 19-24 in the state rotated 45 degree | times from the state of Fig.11 (a) is shown. Moreover, FIG. 12 is a figure which shows the position of a fulcrum similarly to FIG. 11, FIG. 12 (a) has shown the structure of the 1st and 2nd blade | wing members 19-24 in a stop state, 12 (b) shows the configuration of the first and second blade members 19 to 24 in a state rotated 45 degrees from the state of FIG. 12 (a). 11 and 12 show an example in which the vertical rotation shaft 12 rotates clockwise as in the example shown in FIG.

  In the example illustrated in FIG. 11, the first and second blade members 19 to 24 are attached to the horizontal rotation shafts 16 to 18 in an eccentric manner (that is, not at the center but at a position off the center). In such first and second blade members 19 to 24, the long portion is heavier than the short portion, so that the long portion is located below and the short portion is located above when there is no load and no wind. At the same time, the orientation of the plate surface stops at an angle of 45 degrees downward from the horizontal plane.

  In the example shown in FIG. 12, the first and second blade members 19 to 24 are eccentrically attached to the horizontal rotary shafts 16 to 18, and the load 103 is arranged on the short part side. Since the first and second blade members 19 to 24 have a short portion that is heavier than the long portion due to the load 103, the short portion is positioned below and the long portion is the top when there is no load and no wind. And the orientation of the plate surface stops at an angle of 45 degrees downward from the horizontal plane.

  By the way, as shown in FIG. 13, gravity acts on the 1st and 2nd blade | wing members 19-24 eccentrically attached to the horizontal rotating shafts 16-18. FIG. 13 is a diagram showing the action of gravity, FIG. 13 (a) shows the action of gravity in the state shown in FIG. 11 (a), and FIG. 13 (b) is the same as FIG. The action of gravity in the state shown in FIG. 12 shows the action of gravity by taking the configuration shown in FIG. 11 as an example, but the same applies to the configuration shown in FIG.

In the state shown to Fig.13 (a), the rotational moment M shown to the following formula | equation (3) is applied to the 1st and 2nd blade | wing members 19-24. Moreover, in the state shown in FIG.13 (b), the rotation moment M shown to the following formula | equation (4) is applied to the 1st and 2nd blade | wing members 19-24. Here, the length of the elongated portion of the first and second blade members 19 to 24 and l _1, the length of the short portion of the first and second blade members 19 to 24 and l _2, The weight of the long portions of the first blade members 19, 21, 23 is ω _Al , the weight of the short portions of the first blade members 19, 21, 23 is ω _A2, and the second blade members 20, 22, the weight of the elongated portion 24 and omega _Bl, the weight of the short portion of the second blade members 20, 22, 24 and omega _B2.

M = (1/2 × l ₁ × ω _Al × SIN 45 ° + 1/2 × l ₂ × ω _B2
× SIN45 °)-(1/2 × l ₂ × ω _A2 × SIN45 °
+ 1/2 × l ₁ × ω _Bl × SIN45 °) (3)
M = (1/2 × l ₁ × ω _Al ) − (1/2 × l ₂ × ω _A2 ) (4)
Here, as is apparent from FIG. 13B, the first and second blade members 19 to 24 have a difference between the moment of the long portion and the moment of the short portion, so that the rotational moment M is minimized. Can not.

  Therefore, in the present invention, a load is applied to the short portion, that is, the one where the rotational moments of the first and second blade members 19 to 24 are small so that the moment of the long portion and the moment of the short portion are the same. In this way, the weight balance of the first and second blade members 19 to 24 is adjusted so that the rotational moment M calculated by Expression (4) becomes zero.

A simple method for adjusting the weight balance is to make the weight per unit area of the first segment member and the second segment member overlap more than the other. An example is shown in FIG. FIG. 14 is a diagram illustrating a method for adjusting the weight balance. FIG. 14A shows that the load 103 is arranged on the outer end side of the short portion of the first and second blade members 19 to 24 (that is, the side away from the horizontal rotating shafts 16 to 18). Yes. Moreover, FIG.14 (b) shows arrange | positioning the load article 103 in the inner end side (namely, side near the horizontal rotating shafts 16-18) of the short part of the 1st and 2nd blade members 19-24. ing. Further, FIG. 14 (c) shows the use of a heavy material specific gravity than the long part K ₂ to the short portion K _l of the first and second blade members 19 to 24. As the method for adjusting the weight balance, configure thicker than the long part K ₂ of the short portion K _l, or may be configured in multiple layers adhered to the blade member to the short portion K _l .

  In this way, the first and second blade members 19 to 24, whose weight balance is adjusted with respect to the rotational moment, rotate smoothly around the horizontal rotation shafts 16 to 18.

  However, by adjusting the weight balance with respect to such a rotational moment, the first and second blade members 19 to 24 are heavy in either the first segment member or the second segment member (here, the short portion). The moment of inertia increases.

  As described above, in order to minimize the wind energy, it is preferable to reduce the moment of inertia N as much as possible. Therefore, the weight balance with respect to the moment of inertia is also adjusted. Hereinafter, the moment of inertia N will be described in detail.

(Moment of inertia)
The rotational moment M of the first and second blade members 19 to 24 in the state shown in FIG. 15 is expressed by the following equation (5).

M = (1/2 × l ₁ × ω _Al ) − ((1/2 × l ₂ × ω _A2 )
+ (1/2 × l _x × ω _x )) = 0 (5)

The inertia moment N of the first and second blade members 19 to 24 in the state shown in FIG. 15 is the product of the weight of the long portion and the square of the distance from the horizontal rotary shafts 16 to 18 to the center of gravity of the long portion. The product of the weight of the short portion and the square of the distance from the horizontal rotation shafts 16 to 18 to the center of gravity of the short portion, and the weight of the load 103 increased by adjusting the weight balance with respect to the rotation moment and the horizontal rotation shafts 16 to Since this is the sum of the product of the distance from the center of gravity of the load 103 to the square of the load 103, the following equation (6) is obtained. FIG. 15 is a diagram showing the moment of inertia applied to the blade member. Here, the weight of the long portion is ω _Al , the weight of the short portion is ω _A2, and the weight of the load 103 is ω _x .

Further, the length of the long portion is l ₁ , the length of the short portion is l _2, and the distance from the horizontal rotation shafts 16 to 18 to the position where the load 103 is disposed is l _x .

N = (ω _Al × (1/2 × l ₁ ) ² ) + (ω _A2 × (1/2 × l ₂ ) ² )
+ (Ω _x × (1/2 × l _x ) ² ) (6)
From equation (5), ω _x is defined as equation (7) below.

ω _x = ((l ₁ × ω _Al ) − (l ₂ × ω _A2 )) / (l _x ) (7)
By substituting equation (7) into equation (6), the moment of inertia N is defined as the following equation (8).

N = (ω _Al × (1/2 × l ₁ ) ² ) + (ω _A2 × (1/2 × l ₂ ) ² )
+ (((L ₁ × ω _Al ) − (l ₂ × ω _A2 )) × (1/2) ² × l _x )
(8)
Here, (ω _A1 (1/2 × l ₁ ) ² ) + (ω _A2 × (1/2 × l ₂ ) ² ) is a coefficient b, and ((l ₁ × ω _Al ) − (l ₂ × ω _A2 )) × (1/2) When ² is a coefficient a, the moment of inertia N of the equation (8) is defined as the equation (9).

N = a × l + b (9)
Here, the relationship between Expression (7) and Expression (9) is shown as a graph in FIG. In addition, FIG. 16 is a figure which shows the relationship between the arrangement position of a load, and a moment of inertia. In FIG. 16, the curve indicates the relationship between the distance l _x calculated by the equation (7) and the weight ω _x of the load 103, and the straight line indicates the distance l _x calculated by the equation (9). And the moment of inertia N.

As shown in the area Z in FIG. 16, the weight omega _x of the load was 103, according to the distance l _x is small, although larger, according to the moment of inertia N, the distance l _x is small, the minimum value b To approximate. Therefore, when adjusting the weight balance in consideration of both the weight balance with respect to the rotational moment and the weight balance with respect to the moment of inertia, it is preferable to dispose the load 103 so that the distance l _x becomes as small as possible. For example, the arrangement relationship shown in FIG. 17B is preferable to the arrangement relationship shown in FIG. FIG. 17 is a diagram showing a method of adjusting the weight balance, and FIG. 17A shows the load 103 on the outer end side of the short portion (that is, the side away from the horizontal rotating shafts 16 to 18). FIG. 17B shows a state in which the load 103 is arranged on the inner end side of the short portion (that is, the side close to the horizontal rotation shafts 16 to 18). In FIG. 17A, the weight of the load 103 is ω ₃ and the distance from the horizontal rotary rods 16 to 18 to the position where the load 103 is disposed is l ₃ . In FIG. 17B, the weight of the load 103 is ω _4, and the distance from the horizontal rotation shafts 16 to 18 to the position where the load 103 is disposed is l _4. At this time, the weight ω ₃ and the weight and ω _4, a relationship of ω ₃ «ω _4. in addition, the distance _{l 3} and the distance _{l 4,} a relationship of _l 3> l _4.

  As described above, in order to minimize the energy of the wind consumed when the first and second blade members 19 to 24 change the orientation of the plate surface, it is preferable to make the rotational moment M as small as possible. In order to reduce the rotational moment M, the first and second blade members 19 to 24 are set so that the rotational moment M calculated by the equation (4) is as small as possible (that is, 0 or a value close to 0). Adjust the weight balance. Specifically, the difference in rotational moment M generated by the gravity of the first and second segment members is at most less than 0.2 times the larger one of the rotational moment M generated by the gravity of the first and second segment members. If it forms so, the 1st and 2nd blade | wing members 19-24 have little loss of the energy of a wind, and may rotate very smoothly with a slight wind.

Furthermore, in order to minimize the energy of the wind consumed when the first and second blade members 19 to 24 change the orientation of the plate surface, it is preferable to make the moment of inertia N as small as possible. In order to reduce the moment of inertia N, the distance l _x from the horizontal rotation shafts 16 to 18 to the position where the load 103 is arranged, calculated by the equation (7), is made as small as possible (that is, approximate to 0). It is preferable to adjust the weight balance of the first and second blade members 19 to 24 so as to be the same value. Ideally, if the load application position is within 0.1 times the width of the member (i.e., the short portion) to which the load is applied from the horizontal rotation shafts 16 to 18, the first and second blade members 19 are used. ˜24 has little loss of wind energy and may rotate very smoothly with a slight wind.

  In this way, the first and second blade members 19 to 24, in which the weight balance with respect to the rotational moment and the weight balance with respect to the inertia moment are adjusted, rotate in a predetermined direction around the horizontal rotation shafts 16 to 18. Rotating even more smoothly around the horizontal rotation shafts 16 to 18 with a slight wind without consuming almost any wind energy. As a result, the rotation efficiency of the vertical rotation shaft 12 is remarkably improved.

  In addition, the structure of the 1st and 2nd blade | wing members 19-24 used in experiment is shown in FIG. FIG. 18A shows the relationship between the lengths of the first partition member and the second partition member, and FIG. 18B shows the relationship between the length and width of the blade member. In FIG. 18, the horizontal rotation shafts 16 to 18 are indicated by dotted lines as if the horizontal rotation shafts 16 to 18 exist in the first and second blade members 19 to 24. FIG. 5 is a virtual line for explaining the first segment member and the second segment member around the horizontal rotation shafts 16 to 18. Actually, since the horizontal rotation shafts 16 to 18 are attached to the end portions of the first and second blade members 19 to 24, they do not exist in the first and second blade members 19 to 24. .

  In the example shown in FIG. 18A, the protruding length A of the large area portion 101 is larger than the protruding length (= other blade length) B of the small area portion 102, that is, A >> B. So that it is formed.

  The blade members 19 to 24 have different forces for receiving wind force between the large-area portion 101 and the small-area portion 102. The protrusion lengths A and B were preferably about B / A = 10 to 1.5 in the results of actual experiments.

  Further, the efficiency of each blade member 19 to 24 varies depending on the length and width. Each blade member 19-24 has a length C shown in FIG. 18 (b) of several tens of centimeters to several hundred centimeters, and a ratio of the length C to the width D of 5: 1 to 2: About 1 was preferred.

It is preferable that the first and second blade members 19 to 24 stop at an angle of 45 degrees with the plate surface facing downward from the horizontal plane when there is no load and no wind. Therefore, it is preferable that the rotational moment M is slightly different between the long portion and the short portion. That is, it is preferable that the magnitudes of the rotational moment M ₁ and the rotational moment M ₂ around the horizontal rotational axes 16 to 18 of the first and second blade members 19 to 24 are M ₁ > M ₂ .

Further, the difference in magnitude between the rotational moment M ₁ and the rotational moment M ₂ with respect to the larger rotational moment M ₁ (that is, M ₁ −M ₂ ) is as shown in Tables 1 to 3 below in actual experiments. It became. The experiments shown in Tables 1 to 3 were carried out using a blade member having a width of 320 mm and a weight of 1700 g, and changing the protruding length in three ways between the short part and the long part. In Experiment 1, the protrusion length of the long portion is 240 mm, the protrusion length of the short portion is 80 mm, in Experiment 2, the protrusion length of the long portion is 200 mm, and the protrusion length of the short portion is 120 mm. The protruding length of the portion was 170 mm, and the protruding length of the short portion was 150 mm. In the three experiments, the distance from the horizontal rotation shafts 16 to 18 to the position where the load 103 is disposed is l _x , the weight of the load 103 is ω _x, and the rotation moment Ml with respect to the larger rotation moment M _l is The difference in magnitude of the rotational moment M2 (that is, M ₁ −M ₂ ) was defined as Ratio. In all three experiments, good results could be obtained when Ratio was less than 0.2 times.

  In such first and second blade members 19 to 24, the large-area portion 101 is heavier than the small-area portion 102, so that the large-area portion 101 is lower than the small-area portion 102. To work. Therefore, the operation of the first and second blade members 19 to 24 can be stabilized.

  For example, the adjustment of the weight balance of the first and second blade members 19 to 24 can be performed quickly and quickly even when the wind force is small. The members 19 to 24 can be rotated. Therefore, for example, it is particularly effective when receiving a slight wind of a wind speed of 3.4 m / S or less, which is referred to as wind power 2.

<Modifications>
The present invention is not limited to the above-described embodiment, and various modifications and applications can be considered without departing from the gist of the present invention. Hereinafter, some modified examples will be described.

(First modification)
FIG. 19 is a diagram showing a first modification of the power plant using wind. The power device 10 using wind according to the above-described embodiment is provided with a rotation restricting mechanism that stops the rotation of the first and second blade members 19 to 24 at a predetermined angle on the horizontal rotation shafts 16 to 18. On the other hand, in the power device 59 using wind according to the first modification, the vertical rotation shaft 12 is provided with a stopper member serving as an angle regulating mechanism that supports the back portions of the blade members 19 to 24 facing in the vertical direction. ing.

  Specifically, the power unit 59 is provided with base portions of stopper rods 60 to 65, which are examples of stopper members, at positions within the height h of the blade members 19 to 24 immediately below the horizontal rotation shafts 16 to 18. The vertical rotation shaft 12 is fixed. Since the stopper rods 60 to 65 receive the intermediate portion or the tip portion of each blade member 19 to 24, the blade members 19 to 24 are supported at both ends or close to each other. Thereby, the 1st modification can lower the member intensity of each blade member 19-24. That is, each blade member 19-24 can be reduced in weight.

(Second modification)
FIG. 20 is a view showing a second modification of the power device using wind, and FIG. 20 (a) shows the external appearance of the first and second blade members 19 to 24 from an oblique direction. (B) has shown the external appearance from the side surface direction of the 1st and 2nd blade | wing members 19-24. In the second modification, auxiliary wings 111 that intersect the horizontal rotation shafts 16 to 18 at right angles are provided at the outer ends of the first and second blade members 19 to 24. The auxiliary wing 111 has a size of about several centimeters to several tens of centimeters. The auxiliary wing 111 acts to suppress the wind W that is about to slip through the outer ends of the first and second blade members 19 to 24. Thereby, the 2nd modification can improve the force of the wind W concerning the 1st and 2nd blade members 19-24 about several percent-dozens of percent, and converts the energy of the wind W into motive power. Efficiency can be improved. In the following description, when the first and second blade members 19 to 24 are referred to as the auxiliary wing 111 while the portion parallel to the horizontal rotation shafts 16 to 18 is referred to as the main wing 112.

(Third Modification)
FIG. 21 is a diagram showing a third modification of the power unit using wind, and FIG. 21 (a) shows the external appearance of the first and second blade members 19 to 24 from an oblique direction. (B) has shown the external appearance from the side surface direction of the 1st and 2nd blade | wing members 19-24. In the third modification, a groove 113 of several millimeters to several tens of millimeters is provided in the main wing 112 of the first and second blade members 19 to 24 in parallel with the horizontal rotation shafts 16 to 18. The groove 113 acts to contain the wind W. The force of the wind W applied to the first and second blade members 19 to 24 can be improved by several percent to several tens of percent, and the efficiency of converting the energy of the wind W into power can be improved. FIG. 21 shows an example in which the horizontal rotary shafts 16 to 18 are configured to pass through the first and second blade members 19 to 24.

(Fourth modification)
FIGS. 22 and 23 are views showing a fourth modification of the power unit using wind, and FIGS. 22 (a) and 23 (a) are oblique views of the first and second blade members 19-24. FIG. 22B and FIG. 23B show the appearance of the first and second blade members 19 to 24 from the top surface direction. The fourth modification is provided with a rotation setting mechanism that can arbitrarily set the rotation direction of the vertical rotation shaft 12.

  A specific configuration of the rotation setting mechanism is shown in FIG. 24 is an enlarged view of the S portion in FIGS. 22 and 23, FIG. 24 (a) shows a configuration around the horizontal rotation shafts 16 to 18, and FIG. 24 (b) shows an engaging portion (pin). FIG. 24C shows a state in which the pin 122 is fixed to the hole 123 of the horizontal rotation shafts 16 to 18.

  As shown in FIG. 24, the rotation setting mechanism includes a protrusion 121 provided on the horizontal rotation shafts 16 to 18, a pin 122 that engages with the protrusion 121, and the first and second blade members 19 to 24. , And a hole 123 provided around the horizontal rotation shafts 16 to 18. The holes 123 are provided on the left and right sides of the protrusion 121, and the pins 122 are inserted into either of the left and right holes 123 according to the rotation direction of the vertical rotation shaft 12. For example, when the pin 122 is inserted into the right hole 123, the pin 122 supports the first and second blade members 19 to 24 in the state shown in FIG. Therefore, the vertical rotation shaft 12 rotates counterclockwise. When the pin 122 is inserted into the left hole 123, the pin 122 supports the first and second blade members 19 to 24 in the state shown in FIG. Therefore, the vertical rotation shaft 12 rotates clockwise. As described above, in the fourth modification, the rotation direction of the vertical rotation shaft 12 can be arbitrarily set.

  The rotation setting mechanism is not limited to the configuration shown in FIGS. For example, a protrusion similar to the protrusion 121 is provided at a position near the base 11 of the vertical rotation shaft 12, and a plurality of holes similar to the hole 123 are provided in the pulley 28, and a pin similar to the pin 122 is provided in the hole May be inserted.

(Fifth modification)
FIG. 25 is a view showing a fifth modification of the power unit using wind, FIG. 25 (a) shows the configuration around the horizontal rotation shafts 16 to 18, and FIG. 25 (b) shows the first and first configurations. The fixed state of 2 blade | wing members 19-24 is shown. In the fifth modification, the connection between the horizontal rotation shafts 16 to 18 and the first and second blade members 19 to 24 is made rotatable, and instead, the protrusions 121 are provided on the horizontal rotation shafts 16 to 18. In addition, shock absorbers (hydraulic bumpers) 124 are provided on the first and second blade members 19 to 24, and the protrusions 121 and the hydraulic bumpers 124 are engaged with each other.

  The first and second blade members 19 to 24 are fixed to the horizontal rotation shafts 16 to 18 by the protrusion 121 and the hydraulic bumper 124 engaging with each other. For example, the first and second blade members 19 to 24 rotate in the J direction. At this time, the protrusion 121 contacts the hydraulic bumper 124. The position in contact with the protrusion 121 can be set by adjusting the amount of protrusion of the hydraulic bumper 124. The position in contact with the protrusion 121 is set in consideration of the gravity F2 applied to the first blade member 19, 21, 23 or the second blade member 20, 22, 24 pushed up in the horizontal direction. preferable. For example, in the example shown in FIG. 25B, it is assumed that the first blade member 19, 21, 23 or the second blade member 20, 22, 24 pushed up in the horizontal direction sinks by an angle θ by gravity F2. Yes. Therefore, the hydraulic bumper 124 is protruded by an amount in which the orientation of the plate surface of the first blade member 19, 21, 23 or the second blade member 20, 22, 24 is an angle θ, and is pushed up in the horizontal direction. The impact of the first blade member 19, 21, 23 or the second blade member 20, 22, 24 about to sink by the angle θ is reduced.

  Thus, in the fifth modification, the first and second blade members 19 to 24 can be fixed in the direction of an arbitrary plate surface, and the first and second blade members 19 to 24 or In addition, the impact on the horizontal rotary shafts 16 to 18 and the vertical rotary shaft 12 can be alleviated, and wear of these members can be prevented, thereby extending the life of the entire apparatus.

  The shock absorber may be provided on any one of the first and second metal fittings 46, 47 and the first and second metal receiving objects 48, 49. In this case, in particular, wear of the first and second metal fittings 46 and 47 and the first and second metal fittings 48 and 49 can be prevented.

(Sixth Modification)
As shown in FIG. 26, for example, the first and second blade members 19 to 24 can each have an arbitrary size and an arbitrary shape. At this time, the force received from the wind of the first and second blade members 19 to 24 may be different even if the area is the same.

For example, in the configuration shown in FIG. 26, the wind force F received by the inner end side (that is, the side close to the vertical rotation shaft 12) A is expressed by the following formula (10), and the outer end side (that is, the vertical rotation shaft) The force F of the wind received by the portion B (side away from 12) is expressed by the following equation (11). Here, the wind speed is V, the peripheral speed of the inner end side portion A of the first and second blade members 19 to 24 is v _A, and the outer end side of the first and second blade members 19 to 24 is. the peripheral speed of the portion B and v _B, the area of the inner end portion a of the first and second blade members 19 to 24 and S _l, outer end portions of the first and second blade members 19 to 24 the area of the B and _{S 2,} the length of the first and second blade members 19 to 24 and r. Further, the sign indicating the proportional relationship is ∞.

F∞ (V−V _A ) × S _I. . . (10)
F∞ (V−V _B ) × S ₂ . . . (11)
At this time, the relationship between the wind speed V and the circumferential speed v is v = V × r.

Therefore, from the relationship of these equations, if, when the area S ₁ and the area S ₂ of the outer end portion B of the inner end portion A is the same size, the first and second blade members 19 to 24 Receives a greater force from the wind toward the inner end side portion A than the outer end side portion B. Thus, the first and second blade members 19 to 24, by its shape with any of the area S ₁ and the area S ₂ of the outer end portion B of the inner end portion A is the same However, the power received from the wind can be different.
