Description

  The present invention relates to a power conversion device for converting a reciprocating linear motion into a rotational motion in a fixed direction, and a power generation device including the power conversion device.

  Conventionally, a mechanism (a crank mechanism or a cam mechanism) for converting a reciprocating linear motion into a rotational motion in a certain direction has been proposed and put into practical use. In addition, at present, teeth are provided on the inner peripheral surface of an elliptical annular member, and the teeth of the gear arranged inside the annular member are engaged with the teeth of the annular member, so that the reciprocating motion of the annular member is constant. A mechanism for converting into a rotational motion in a direction has been proposed (see Patent Document 1).

JP 2009-270706 A

  However, in the power conversion by the crank mechanism, the transmitted force differs depending on the rotational position angle of the crankshaft, and the reciprocating linear motion force is efficiently converted into the rotational motion at an angle near the connecting rod and the crank arm. There is a problem that it cannot be converted into force (torque). Further, power conversion by the cam mechanism is not suitable for power generation that requires high torque because the force (torque) of the generated rotary motion is extremely small. Further, in the mechanism described in Patent Document 1, in order to realize the rotational movement of the gear in a certain direction, it is necessary not only to reciprocate the annular member linearly but also to reciprocate in the lateral direction. Since a special auxiliary mechanism is required to control the trajectory, there is a problem that the application range is limited.

  Further, the stroke length of the reciprocating linear motion in these conventional mechanisms is constant, and cannot cope with the reciprocating linear motion (for example, up and down motion of the wave) in which the stroke length changes every moment. Moreover, in such a conventional mechanism, there is a possibility that it cannot be adapted to a large-scale reciprocating linear motion having a stroke length of several meters or more.

  The present invention has been made in view of such circumstances, and provides a power conversion device capable of efficiently converting a large-scale reciprocating linear motion whose stroke length changes from moment to moment into a rotational motion in a constant direction. The purpose is to do.

  To achieve the above object, a power conversion device according to the present invention includes a power conversion mechanism that converts a reciprocating linear motion of a reciprocating member into a continuous rotational motion of two rotating members that rotate in opposite directions. Is. The power conversion device includes a first rotating member (for example, in the form of a gear) provided on the first shaft and a first rotating member (for example, in the form of a flywheel) that are separated from the first shaft by a predetermined distance. A second rotating member (for example, in the form of a gear) and a second rotating member (for example in the form of a flywheel) provided on a second shaft arranged in a The rotating members are engaged to perform rotational movements in opposite directions. The power conversion mechanism converts the power of the first linear motion of the reciprocating member into the first rotational motion of the first rotating member, while the power of the second linear motion of the reciprocating member is converted to the second power. Power conversion means (for example, a chain or the like) that converts the second rotation motion of the rotation member is provided. Further, the power conversion mechanism transmits the power of the first rotation motion of the first rotation member to the first rotation member to realize the rotation motion of the first rotation member, while the first rotation The first power transmission means (such as a one-way clutch) that does not transmit the power of the second rotating motion of the member to the first rotating member and the power of the second rotating motion of the second rotating member. While transmitting to the second rotating member to realize the rotating motion of the second rotating member, the power of the first rotating motion of the second rotating member is not transmitted to the second rotating member (for example, a one-way clutch) Etc.) second power transmission means.

  When this configuration is adopted, the power of the first linear motion of the reciprocating member is converted into the first rotational motion of the first rotational member, and the first rotational motion of the first rotational member is converted. The power is transmitted to the first rotating member to realize the rotational motion of the first rotating member, and further the power of the rotational motion of the first rotating member is transmitted to the second rotating member to perform the second rotation. A rotational motion in the direction opposite to the first rotational member of the member (same direction as the second rotational motion) can be realized. At this time, even when the second rotating member performs the first rotating motion during the first linear motion of the reciprocating member, the first rotating motion of the second rotating member is also reduced. Since power is not transmitted to the second rotating member, the rotating motion of the second rotating member is not hindered, and the rotating motion of the first and second rotating members is maintained.

  On the other hand, the power of the second linear motion of the reciprocating member is converted into the second rotational motion of the second rotational member, and the power of the second rotational motion of the second rotational member is converted to the second rotational motion. To the rotating member of the second rotating member to realize the rotating motion of the second rotating member, and further to transmit the power of the rotating motion of the second rotating member to the first rotating member. Rotational motion in the opposite direction to the rotating member (same direction as the first rotational motion) can be realized. At this time, even when the first rotating member performs the second rotating motion during the second linear motion of the reciprocating member, the second rotating motion of the first rotating member is also reduced. Since power is not transmitted to the first rotating member, the rotating motion of the first rotating member is not hindered, and the rotating motion of the first and second rotating members is maintained.

  As a result, the powers of both the first linear motion and the second linear motion of the reciprocating member are efficiently converted into the continuous rotational motion of the first and second rotating members. In this power conversion device, since it is not necessary to regulate the movement of the reciprocating member so as to draw a special trajectory, the application range is extremely wide. For example, a large-scale reciprocating straight line whose stroke length changes greatly. It can be applied to power conversion of motion.

  In the power converter, gear-like flywheels having teeth formed on the outer periphery may be adopted as the first and second rotating members.

  Thus, if a gear-like flywheel is employ | adopted as a 1st and 2nd rotation member, two rotation members can be engaged reliably.

  Further, in the power conversion device, a tooth portion is formed on the outer periphery of the first and second rotating members, and a chain is wound around the outer periphery of the first and second rotating members so as to be engaged with the tooth portion, thereby reciprocating. A power conversion means can be comprised by connecting a member and a chain with a connection member.

  When such a configuration is adopted, the power of the reciprocating linear motion of the reciprocating member can be converted into the rotational motion of the rotating member via the connecting member and the chain.

  In the power conversion device, the tooth portion is formed on one surface of the reciprocating member, the tooth portion is formed on the outer periphery of the first and second rotating members, and meshed with the tooth portion of the reciprocating member. The power conversion means may be configured by arranging a power conversion rotating member having a tooth portion meshing with a tooth portion of the first and second rotating members between the first and second rotating members.

  When such a configuration is adopted, the power of the reciprocating linear motion of the reciprocating member is converted into the rotational motion of the first and second rotating members via the power converting rotating member without using a chain. be able to.

  Further, in the power conversion device, a third shaft is disposed at a predetermined distance from the first shaft in the opposite direction to the second shaft, and the rotational movements in the opposite directions about the third shaft are arranged. Third and fourth rotating members rigidly coupled to the third shaft can be provided. In such a case, the second and third rotating members are arranged on the opposite side of the first and fourth rotating members across the plane including the rotating members, and tooth portions are formed on the outer periphery of each rotating member. Then, the first chain is wound around the outer periphery of the second and third rotating members so as to mesh with the tooth portion, the reciprocating member and the first chain are connected by the connecting member, and the first and fourth rotations are performed. The power conversion means can be configured by winding the second chain around the outer periphery of the moving member so as to mesh with the teeth.

  When such a configuration is adopted, the power of the reciprocating linear motion of the reciprocating member is transmitted via the connecting member, the first chain, the third rotating member, the third shaft, the fourth rotating member, and the second chain. Thus, it can be converted into a turning motion of the turning member. In addition, since the third axis is disposed on the opposite side of the second axis across the first axis, the distance between the second axis and the third axis is the first axis and the first axis. It becomes longer than the distance (diameter of the rotating member) between the two axes. For this reason, a 3rd rotation member will be arrange | positioned in the position far away from the 2nd rotation member, and the 1st chain wound around the 2nd and 3rd rotation member can be lengthened. . Since the reciprocating member is connected to the long first chain by the connecting member, the reciprocating linear motion of the reciprocating member with a long stroke exceeding the diameter of the rotating member can be allowed. Therefore, it is possible to efficiently convert a long stroke reciprocating linear motion into a rotational motion.

  Moreover, the electric power generating apparatus which concerns on this invention is provided with the said power converter device and the generator which generate | occur | produces electric power by the rotational motion of the rotating member of the said power converter device. Such a power generation device may include a floating member that is attached to the reciprocating member of the power conversion device and floats on the sea surface and reciprocates up and down by wave force. Moreover, you may provide the wing | blade member which converts the flowing water energy of an irrigation channel or a river into the reciprocating linear motion of the reciprocating member of the said power converter device.

  When such a configuration is adopted, the revolving motion of the floating member due to the wave force and the flow energy of the water channel or river converted into the reciprocating linear motion of the reciprocating member by the wing member are continuously rotated by the rotating member of the power converter. It is possible to efficiently convert to motion and generate electric power by this rotational motion. In particular, since the power generation device employs the power conversion device described above, it is possible to efficiently generate electric power by using the energy of up and down movement of an irregular wave whose stroke length changes.

  According to the present invention, it is possible to provide a power conversion device that can efficiently convert a large-scale reciprocating linear motion whose stroke length changes from moment to moment into a rotational motion in a constant direction.

The wave power generator 1 includes a floating member 2 that floats on the sea surface and reciprocates up and down by wave force, and a power conversion device that converts the energy of the reciprocating motion of the floating member 2 into rotational energy of the rotating members 31 and 32. 3 and a generator 4 that generates electric power by the rotational energy of the rotating members 31 and 32 of the power conversion device 3.

  As shown in FIGS. 1 to 3, the floating member 2 is a member made of a material having an appropriate specific gravity so that it floats on the sea surface due to the buoyancy of seawater. Since the waves perform irregular up-and-down movements with varying stroke lengths, the floating member 2 also performs irregular up-and-down reciprocating movements accordingly.

  The power conversion device 3 is attached to the floating member 2 and revolves around the first shaft 11 that is horizontally disposed, and a reciprocating member 10 that reciprocates up and down integrally with the floating member 2 by wave force. The first rotating member 21 to be performed, the second rotating member 22 to perform the rotating motion around the second shaft 12 arranged at a predetermined distance from the first shaft 11 and the lower shaft, the first shaft 11 includes a first rotating member 31 that rotates in a predetermined direction around 11, a second rotating member 32 that rotates around the second shaft 12, and the like.

As shown in FIGS. 1 and 2, the reciprocating member 10 is a columnar member arranged so as to extend in the vertical direction, and the floating member 2 is attached to the lower end thereof. Reciprocating member 10, linear movement (the second to the floating member 2 integrally with the upper linear movement (first linear movement) to (L ₁ direction in FIG. 1) and lower (L ₂ direction in FIG. 1) Linear motion). For the purpose of stabilizing the reciprocating motion of the reciprocating member 10, it is preferable to install an annular or cylindrical guide member, and to support the slidable member 10 slidably inserted into the guide member. Such a guide member can be installed on a structure where the power conversion device 1 is installed (for example, the base 5 fixed to the seabed) to support the reciprocating member 10.

The first rotating member 21 is configured to perform first and second rotating motions in opposite directions (R ₁ and R ₂ directions shown in FIG. 1) around the first shaft 11. The second rotating member 22 is configured to perform first and second rotating motions in opposite directions (R ₁ and R ₂ directions shown in FIG. 1) around the second shaft 12. Has been. The first and second rotating members 21 and 22 have a gear-like configuration in which tooth portions (not shown) are formed on the outer periphery thereof. The first and second rotating members 21 and 22 can be made of a metal material or the like. In this embodiment, as shown in FIG.1 and FIG.2, both the 1st and 2nd rotation members 21 * 22 are arrange | positioned at the single side | surface side of the rotation members 31 * 32.

The first rotating member 31 is configured to perform a rotational motion in the R ₁ direction shown in FIG. 1 about the first shaft 11. The second rotating member 32 is disposed such that the outer peripheral portion thereof is engaged with the outer peripheral portion of the first rotating member 31 and energy of rotational motion of the first rotating member 31 is transmitted. It is configured about the axis 12 of the first rotary member 31 in the opposite direction to the rotation movement of the (R ₂ direction shown in FIG. 1). The first and second rotating members 31 and 32 may be configured so that the outer peripheral portions thereof engage with each other, and for example, a rubber tire or a gear-like flywheel having tooth portions formed on the outer periphery is employed. be able to. The first shaft 11 is rigidly coupled to the rotation center of the first rotation member 31 and rotates together with the first rotation member 31. On the other hand, the second shaft 12 is rigidly coupled to the rotation center of the second rotating member 32 and rotates together with the second rotating member 32.

A chain 23 is wound around the outer periphery of the first and second rotating members 21 and 22 so as to mesh with the tooth portion, and the chain 23 is connected to the reciprocating member 10 via the connecting member 20. For this reason, the energy of the reciprocating motion of the reciprocating member 10 is converted into the rotational motion of the first and second rotating members 21 and 22 via the connecting member 20 and the chain 23. Specifically, reciprocating linear motion (first linear movement) upward (L ₁ direction in FIG. 1) of the member 10 is rotated in the R ₁ direction of the first and second rotating members 21 and 22 On the other hand, the linear motion (second linear motion) in the downward direction (L ₂ direction in FIG. 1) of the reciprocating member 10 is converted in the R ₂ direction of the first and second rotating members 21 and 22. It is converted into a rotational movement. The connecting member 20 and the chain 23 constitute power conversion means in the present invention.

A one-way clutch (not shown) is provided between the first rotating member 21 and the first shaft 11. As a result, the power of the first rotational movement (R ₁ direction shown in FIG. 1) of the first rotational member 21 is transmitted to the first rotational member 31 via the first shaft 11, and while rotational movement in a predetermined direction of the rotary member 31 (R ₁ direction shown in FIG. 1) is achieved, the power of the second rotational movement of the first pivot member 21 (R ₂ direction shown in FIG. 1) It is not transmitted to the first rotating member 31. A one-way clutch is also provided between the second rotating member 22 and the second shaft 12. As a result, the power of the second rotating motion (R ₂ direction shown in FIG. 1) of the second rotating member 22 is transmitted to the second rotating member 32 via the second shaft 12, and the second rotating member 22 is transmitted. While the rotational movement of the rotating member 32 in the R ₂ direction shown in FIG. 1 is realized, the power of the first rotating movement (R ₁ direction shown in FIG. 1) of the second rotating member 22 is the second rotation. It is not transmitted to the member 32. These one-way clutches correspond to the first and second power transmission means in the present invention.

  The generator 4 generates electric power by the rotational energy of the rotating shaft 34 of the power generation gear 33 disposed so as to mesh with the first rotating member 31 of the power conversion device 3. In the present embodiment, as shown in FIGS. 2 and 3, the generator 4 is disposed on one end side of the rotating shaft 34 of the power generation gear 33. The generator 4 is connected to a rotating shaft 34 and generates electric power by increasing the rotation of the rotating shaft 34 with a speed increaser. In this embodiment, as shown in FIGS. 1-3, the edge part of the 1st and 2nd axis | shafts 11 * 12 of the power converter device 3 is set rather than the sea surface by the set of foundation 5 fixed to the seabed. It is supported rotatably at the upper position. Accordingly, the rotating members 21 and 22 and the rotating members 31 and 32 of the power conversion device 3 and the generator 4 are always arranged above the sea level regardless of the vertical reciprocating motion of the floating member 2. In FIG. 1, for convenience of explanation of the configuration of the power conversion device 3, the generator 4 and the power generation gear 33 are not shown, and the base 5 is indicated by a broken line.

  Next, operation | movement of the wave power generator 1 which concerns on this embodiment is demonstrated using FIG.1, FIG4 and FIG.5. In FIGS. 4 and 5, the generator 4 and the base 5 are not shown for convenience of explanation of the operation of the power conversion device 3.

In the following description, it is assumed that the wave power generation device 1 is operated with the state shown in FIG. 1 as an initial state. In the initial state, the connecting member 20 that connects the reciprocating member 10 and the chain 23 is located at the center in the vertical direction (near the engaging portion of the first and second rotating members 31 and 32). upper member 10 has a possible linear movement to and lower (L ₁ direction in FIG. 1) (L ₂ direction in FIG. 1).

From this initial state, when the float member 2 is pushed upward as shown in FIG. 4 by the wave power, in association with this reciprocating member 10 of the power converter 3 a linear movement upwards (L ₁ direction) performed, power of the linear motion is transmitted to the first rotating member 21 via the connecting member 20 and the chain 23, the first rotating member 21 performs rotational movement of R ₁ direction. At this time, linear motion of the power of the reciprocating member 10 is also transmitted to the second rotating member 22, as well the second rotating member 22 performs rotational movement of R ₁ direction.

R ₁ direction rotational movement of the power of the first rotating member 21 is transmitted to the first rotary member 31 via the one-way clutch and the first shaft 11, the first rotary member 31 is R ₁ direction Rotating movement. The rotary motion of the power of the first rotary member 31 is transmitted to the second rotary member 32 which is engaged with the first rotary member 31, a second rotary member 32 is rotational motion of R ₂ direction I do. In this case, R ₁ direction of the rotational movement of the power of the second rotating member 22, since the function of the one-way clutch not transmitted to the second rotating member 32, the second rotary member 32 a second pivot R ₂ direction rotational movement can be performed without being affected by the member 22.

In this manner, the energy of the linear motion of the upper float member 2, the rotational motion of the R ₁ direction of the first rotary member 31 of the power converter 3 and the rotational motion of the R ₂ direction of the second rotating member 32 Is converted to

Next, from the state shown in FIG. 4, when the float member 2, as shown in FIG. 5 by the wave power is pushed downward, the reciprocating member 10 of the power converting apparatus 3 downward along with this (L ₂ direction) to perform linear movement, the power of the linear motion is transmitted to the second rotating member 22 through the connecting member 20 and the chain 23, the second rotating member 22 performs rotational movement of the R ₂ direction. At this time, linear motion of the power of the reciprocating member 10 is also transmitted to the first rotating member 21, as well the first rotating member 21 performs rotational movement of the R ₂ direction.

R ₂ direction of rotational movement of the power of the second rotating member 22 is transmitted to the second rotary member 32 through the one-way clutch and a second shaft 12, a second rotary member 32 is R ₂ direction Rotating movement. Then, the power of the rotational movement of the second rotary member 32 is transmitted to the first rotary member 31 is engaged with the second rotary member 32, the first rotary member 31 is rotational motion of R ₁ direction I do. At this time, the power of the R ₂ direction of rotational movement of the first rotating member 21, since the function of the one-way clutch not transmitted to the first rotary member 31, the first rotating member 31 is first rotated The rotational movement in the R ₁ direction can be performed without being affected by the member 21.

Thus, the energy of the linear motion downward of the floating member 2 is the rotational motion of the first rotating member 31 of the power converter 3 in the R ₁ direction and the rotational motion of the second rotating member 32 in the R ₂ direction. Is converted to

  That is, the energy of the up-and-down reciprocating motion of the floating member 2 (and the up-and-down reciprocating motion of the reciprocating member 10 of the power conversion device 3) is the energy of the first and second rotating members 31 and 32 of the power conversion device 3. It will be converted into a continuous rotational motion. The energy of the rotational motion of the first and second rotating members 31 and 32 obtained in this way is transmitted to the generator 4 through the rotating shaft 34 of the power generating gear 33 and converted into electric power. .

In the power conversion device 3 according to the embodiment described above, the power of the linear motion upward of the reciprocating member 10 is converted into the rotational motion of the first rotational member 21 in the R ₁ direction. The power of the rotating motion of the rotating member 21 is transmitted to the first rotating member 31 to realize the rotating motion in the R ₁ direction of the first rotating member 31 and the rotating motion of the first rotating member 31. Can be transmitted to the second rotating member 32 to realize the rotational motion of the second rotating member 32 in the R ₂ direction. During the linear motion upward of the reciprocating member 10, the second rotating member 22 performs the rotating motion in the R ₁ direction, but the power of this rotating motion is not transmitted to the second rotating member 32. The rotational motion of the second rotating member 32 is not hindered, and the rotational motion of the first and second rotating members 31 and 32 is maintained.

On the other hand, the power of the downward linear motion of the reciprocating member 10 is converted into the rotational motion of the second rotational member 22 in the R ₂ direction, and the rotational power of the second rotational member 22 is converted into the first rotational motion. The second rotating member 32 is transmitted to realize the rotational motion of the second rotating member 32 in the R ₂ direction, and the power of the rotational motion of the second rotating member 32 is transmitted to the first rotating member 31. the rotational motion of the R ₁ direction of the first rotary member 31 can be realized Te. When the reciprocating member 10 is linearly moved downward, the first rotating member 21 performs a rotating motion in the R ₂ direction, but the power of this rotating motion is not transmitted to the first rotating member 31. The rotational motion of the first rotating member 31 is not hindered, and the rotational motion of the first and second rotating members 31 and 32 is maintained.

  As a result, the power of both the linear motion upward and the linear motion downward of the reciprocating member 10 is efficiently converted into the continuous rotational motion of the first and second rotating members 31 and 32. Become.

  Further, in the wave power generation device 1 according to the embodiment described above, the vertical reciprocating motion of the floating member 2 due to the wave force is efficiently converted into the continuous rotational motion of the rotating members 31 and 32 of the power conversion device 3. Electric power can be generated by this rotational movement. Since the wave power generation device 1 according to the present embodiment employs the power conversion device 3, it is possible to efficiently generate electric power by using the energy of the up and down movement of an irregular wave whose stroke length greatly changes. it can.

The rotary motion of the power of the first rotary member 31 is transmitted to the second rotary member 32 which is engaged with the first rotary member 31, a second rotary member 32 is rotational motion of R ₄ Direction I do. In this case, R ₃ direction of rotational movement of the power of the second rotating member 22, since the function of the one-way clutch not transmitted to the second rotating member 32, the second rotary member 32 a second pivot The rotational movement in the R ₄ direction can be performed without being affected by the member 22.

In this manner, the energy of the linear motion of the upper float member 2, the rotational motion of the R ₄ direction of the first rotation and a second R ₃ direction of the rotating member 31 of the rotary member 32 of the power conversion device 3A Is converted to

Next, when the floating member 2 is pushed downward by the wave force from the state shown in FIG. 9, the reciprocating member 10 of the power conversion device 3 </ b> A is lowered (L ₂ direction). to perform linear movement, the linear movement of the power is transmitted to the second rotating member 22 through the connecting member 20 and the first chain 43, the second rotating member 22 is R ₄ direction of rotational movement I do. At this time, linear motion of the power of the reciprocating member 10 is also transmitted to the first rotating member 21, as well the first rotating member 21 performs rotational movement R ₄ directions.

When the reciprocating member 10 is linearly moved upward, the second rotating member 22 rotates in the R ₃ direction, but the power of this rotating motion is not transmitted to the second rotating member 32. The rotational motion of the second rotating member 32 is not hindered, and the rotational motion of the first and second rotating members 31 and 32 is maintained.

When the reciprocating member 10 is linearly moved downward, the first rotating member 21 performs a rotating motion in the R ₄ direction, but the power of this rotating motion is not transmitted to the first rotating member 31. The rotational motion of the first rotating member 31 is not hindered, and the rotational motion of the first and second rotating members 31 and 32 is maintained.

  As a result, the power of both the linear motion upward and the linear motion downward of the reciprocating member 10 is efficiently converted into the continuous rotational motion of the first and second rotating members 31 and 32. Become.

  Moreover, in the wave power generation device 1A according to the embodiment described above, the vertical reciprocating motion of the floating member 2 due to the wave force is efficiently converted into the continuous rotational motion of the rotating members 31 and 32 of the power conversion device 3A.

Furthermore, electric power can be generated using this rotational energy.

However, the configuration for transmitting the energy of the rotational motion of the first rotating member 31 to the generator 4 is not limited to this. For example, as shown in FIG. 11, a chain 37 is wound around a gear 35 that rotates around the first shaft 11 together with the first rotating member 31 and a gear 36 that is attached to the rotating shaft 4 a of the generator 4.
