Description

  The present invention relates to a gravity power generation apparatus that generates power using gravity.

  In recent years, renewable energy has attracted attention from the viewpoint of the prevention of global warming due to exhaustion of energy resources such as oil and the emission of carbon dioxide. In recent years, research has been actively conducted on renewable energy, such as solar power, which uses light, and wind power, which uses wind. There has been no research. However, since gravity is inexhaustible, if it can be used to generate electricity, it can bring great benefits to mankind.

  For example, Patent Document 1 is known as a conventional technique related to gravity power generation. Patent Document 1 discloses a gravity power generation device that generates electric power by converting a descending action of gravity into a rotational force. Specifically, the following is disclosed. Rollers 2 are attached to both ends of a solid rectangular slide body 4 having no rotation axis, and stored in a cylindrical rectangular parallelepiped 5. Then, a plurality of rectangular parallelepipeds 5 are connected to the rotary shaft A. Then, only the roller 2 on one side of the rectangular parallelepiped 5 is grounded to the concave touch wall 1. As a result, the opposite end of the rectangular slide body 4 descends, and using this descending behavior, the rectangular parallelepiped 5 is rotated, the rotating shaft A is rotated, and the generator is activated.

JP 2009-299672 A

  However, in Patent Document 1, it is described that a plurality of rectangular parallelepipeds 5 are provided on the rotary shaft A, and the rectangular parallelepiped 5 is rotated using the descending action of the rectangular slide body 4 accommodated in the rectangular parallelepiped 5. There is no detailed description of how rotational motion occurs from this descending action. Therefore, it is unclear whether the rotating shaft A can be continuously rotated to generate electric power.

  The objective of this invention is providing the gravity power generation apparatus and gravity power generation system which generate | occur | produce electric power using gravity.

  (1) A gravitational power generation apparatus according to the present invention includes an oscillating body, a support portion that oscillates the oscillating body, a moving body that is movably attached in a longitudinal direction of the oscillating body, When one end reaches the lowest swing position, a restoring force is applied to the swing body, the one end is returned to the highest swing position, and the other end of the swing body reaches the lowest swing position. A restoring portion that applies a restoring force to the oscillating body and returns the other end of the oscillating body to the uppermost oscillating position, and the moving body is a gravity applied in a longitudinal direction of the oscillating body when the oscillating body is inclined. A rotating body that rotates based on a component and moves the moving body in the longitudinal direction of the rocking body, and a generator that generates electric power by the rotational force of the rotating body, and the restoring portion is generated by the generator. The restoring force is applied to the rocking body using a part of the generated electric power.

  According to this structure, the rocking body is supported by the support portion so as to be rockable. The moving body is attached so as to be movable in the longitudinal direction of the rocking body. Therefore, when the other end of the oscillating body is lower than the one end and the oscillating body is inclined, the moving body moves from one end of the oscillating body toward the other end. Then, the rotating body rotates as the moving body moves, and the generator receives the rotational force of the rotating body to generate power.

  When the other end of the oscillating body reaches the lowermost oscillating position, the other end of the oscillating body starts to move again toward the uppermost oscillating position by the restoring force from the restoring portion. At this time, the restoration unit is driven by using a part of the electric power generated by the generator. When one end of the rocking body becomes lower than the other end and the rocking body is inclined, the moving body moves from the other end of the rocking body toward the one end. Then, the rotating body rotates as the moving body moves, and the generator receives the rotational force of the rotating body to generate power.

  When one end of the oscillating body reaches the lowermost oscillating position, the one end of the oscillating body receives a restoring force from the restoring portion and moves again toward the uppermost oscillating position. In other words, the oscillating body is oscillated like a seesaw by receiving a restoring force from the restoring unit, and the moving body repeats the movement along the oscillating body along with this oscillating, and each time the moving body moves, the generator Electric power is generated. As a result, power can be generated using gravity. Further, since the restoring unit is driven by using a part of the electric power generated by the generator, the oscillating body can continue to oscillate even when no electric power is supplied from the outside.

  (2) The support portion is attached to both ends of the oscillating body such that when one end of the oscillating body is located at the uppermost oscillating position, the other end of the oscillating body is located at the lowermost oscillating position. A pair of support plates and a pair of support rods that pivotally support the pair of support plates, and the restoring portion is configured such that when one end of the swing body reaches the lowest swing position, The pair of support plates are rotated to apply the restoring force to the rocking body, and when the other end of the rocking body is located at the lowest rocking position, the pair of support plates are rotated to rotate the rocking body. It is preferable to apply the restoring force to the moving body.

  According to this configuration, when the movable body reaches the lowest swing position, the movable body is lifted to the highest swing position by the rotation operation of the support plate. Therefore, the power consumption of the restoring unit when rotating the support plate can be further reduced, and efficient power generation can be realized.

  (3) It is preferable that a plurality of the oscillators exist.

  According to this structure, more electric power can be generated using a plurality of oscillators.

  (4) The oscillating body includes first and second oscillating bodies, and the pair of support plates includes the second oscillating body when one end of the first oscillating body is located at the uppermost oscillating position. It is preferable that the first and second rocking bodies are attached to both ends so that the ends are located at the uppermost rocking position.

  According to this configuration, the first oscillating body and the second oscillating body are provided so as to intersect with each other, and the support plate can rotate the first and second oscillating bodies in a balanced manner. Each of the first and second oscillators may be plural or one.

  (5) It is preferable that the plurality of oscillating bodies are attached to the pair of support plates so that their longitudinal directions are parallel to each other.

  According to this configuration, since the plurality of oscillating bodies are attached to the support plate so that the longitudinal directions thereof are parallel to each other, the movable bodies provided on the oscillating bodies move side by side.

  (6) It is preferable that the oscillating body includes a stopper that protrudes and appears in a moving path of the rotating body during the rotation of the support plate, and abuts on the rotating body to regulate the movement of the moving body.

  According to this configuration, the stopper moves in and out of the moving path of the moving body during the rotation operation of the support plate, and the movement of the moving body is restricted by contacting the rotating body. Therefore, the moving body can be moved toward the lowest swing position after being lifted to the highest swing position. As a result, the rotating body is prevented from starting to move before reaching the uppermost swing position, and the moving body can be dropped from a higher position, and more electric power can be generated.

  (7) The oscillating body is provided in a direction perpendicular to the traveling direction of the moving body at each of the one end and the other end, and bends when the moving body comes into contact with the moving body. It is preferable to provide an absorber that absorbs water.

  According to this configuration, when the moving body reaches the lowest swing position, the collision between the moving body and the support plate is avoided, and damage to both members can be prevented.

  (8) It is preferable that the rotating body has a disk shape, and the swinging body includes a pair of upper and lower rail portions that sandwich the rotating body from a direction of a circumferential surface of the rotating body.

  According to this configuration, the rotating body is sandwiched between the pair of rail portions from the circumferential surface direction and mounted on the swinging body. Therefore, even when the swinging body is turned upside down by the rotation of the support plate, the moving body can be prevented from falling off the swinging body.

  (9) The support portion includes a support rod that pivotally supports the rocking body at a center in a longitudinal direction of the rocking body, and a pair of lever rods connected to both ends of the rocking body, The restoring part preferably applies the restoring force to the rocking body via a lever part connected to the other end.

  According to this configuration, since the restoring force is applied to the oscillating body using the pair of lever rods connected to both ends of the oscillating body, the movable body can be lifted to the uppermost oscillating position with a smaller restoring force.

  (10) The support portion includes a pair of regulating rods that regulate the oscillation of the oscillating body by abutting against one end and the other end of the oscillating body, and the regulating rod is in contact with the oscillating body. It is preferable to provide an elastic body that absorbs the force of the rocking body.

  According to this configuration, the restricting body can absorb an impact when the rocking body comes into contact, and can prevent the restricting body and the rocking body from being damaged.

  (11) It is preferable to further include a power transmission unit that increases the angular velocity of the generator more than the angular velocity of the rotating body and transmits the rotational force of the rotating body to the generator.

  According to this configuration, since the generator is rotated by increasing the angular velocity as compared with the rotating body, the power generation efficiency can be further increased.

  (12) It is preferable that the power transmission unit transmits the rotational force of the rotating body to a plurality of generators.

  According to this configuration, since a plurality of generators are provided on one rotating shaft, more power can be generated efficiently.

  (13) It is preferable that the rocking body includes a guide portion for guiding the movement of the moving body in the longitudinal direction, and the moving body includes a pulley that moves along the guide portion.

  According to this configuration, the moving body can move smoothly with respect to the rocking body.

  (14) It is preferable to further include a storage battery for storing the electric power generated by the generator.

  According to this structure, since the storage battery which stores the electric power generated by the generator is provided, the generated electric power can be used when necessary.

  (15) A gravitational power generation system according to the present invention includes a plurality of the gravitational power generation devices, and includes a restoration control unit that drives the restoration unit of each oscillating body so that the phase of each oscillating body is shifted.

  According to this configuration, even if a certain gravity power generation device is not generating power, another gravity power generation device generates power, and the gravity power generation system can always be in a power generation state.

  According to the present invention, the oscillating body receives a restoring force from the motor and oscillates like a seesaw. With this oscillation, the movable body repeatedly moves on the oscillating body, and each time the movable body moves. Electric power is generated by the generator. As a result, power can be generated using gravity.

FIG. FIG. 16 is a sequence diagram illustrating a state in which the number of oscillating bodies is four and the moving bodies provided on each of the four oscillating bodies are moved.

  FIG. 1 is an overall configuration diagram of a gravity power generation apparatus according to an embodiment of the present invention. The gravitational power generation apparatus includes an oscillating body 11, a moving body 12, a support section 13, a pair of lever sections 14 and 15, a pair of motors 18 and 19, a control section 101, and a power storage section 102.

  In FIG. 1, + z indicates an upward direction, -z indicates a downward direction, + x indicates a rightward direction, -x indicates a leftward direction, + y indicates a forward direction, and -y indicates a backward direction. . Also, the upper direction and the lower direction are combined to describe the up and down direction, the left direction and the right direction are combined to describe the left and right direction, and the front direction and the rear direction are combined to describe the width direction.

  The oscillating body 11 has an elongated shape whose longitudinal direction is the left-right direction, and a hinge 131 is attached to the center position of the lower surface 111. Then, the swinging body 11 swings in the pitch direction around the hinge 131 in the xz plane.

  The moving body 12 is attached so as to be movable in the longitudinal direction of the rocking body 11. The support unit 13 includes a hinge 131, a support bar 132, and a pair of regulation bars 133 and 134. The support unit 13 swings the swinging body 11 like a seesaw within a range of a predetermined angle θ. The support bar 132 is mounted on the ground E, is configured by a bar having a vertical direction in the vertical direction, and a hinge 131 having a longitudinal direction in the width direction is attached to the upper surface 135. Accordingly, the support bar 132 swings the swing body 11 in the pitch direction around the hinge 131.

  Hereinafter, the state where the rocking body 11 is positioned in parallel with the ground E is referred to as a horizontal state. The swing angle of the swing body when the swing body 11 is in the horizontal state is 0 degree, and the swing angle when the left end 112 of the swing body 11 is located below the horizontal state is positive. The swing angle is defined such that the swing angle when the left end 112 is positioned above the horizontal state is negative. Further, it is described that when the swing angle of the swing body 11 is + θ / 2, the left end 112 of the swing body 11 is located at the lowest swing position. Further, it is described that when the swing angle of the swing body 11 is −θ / 2, the right end 113 of the swing body 11 is located at the uppermost swing position.

  The restriction rods 133 and 134 are placed on the ground E, and are constituted by rods whose longitudinal direction is the vertical direction, and the lower surface 111 of the left end 112 (an example of one end) and the right end 113 (an example of the other end) of the oscillator 11 and By abutting, the swinging of the swinging body 11 is restricted.

  FIG. 4 is a cross-sectional view in the width direction (yz plane) of the regulation rod 133. The restriction bar 134 has the same configuration as that of the restriction bar 133, and thus the description thereof is omitted. The restriction rod 133 includes a contact part 41, a cylinder part 42, a spring 43, and a base 44. The abutting portion 41 abuts on the lower surface 111 of the oscillating body 11, and includes a receiving portion 411 that receives the oscillating body 11 and a support bar 412 that is attached to the lower side of the receiving portion 411 and supports the receiving portion 411. I have.

  The receiving part 411 has a substantially U-shaped depression on the lower side, and the rocking body 11 enters the inner side 413. The support rod 412 is a rod attached to the center of the bottom portion 414 of the receiving portion 411 and extending from the bottom portion 414 toward the −z direction. The bottom portion 414 contacts the lower surface 111 of the rocking body 11.

  The cylindrical portion 42 is open on the upper side, has a base 44 attached on the lower side, has a cylindrical shape with the vertical direction as the longitudinal direction, and accommodates the support bar 412 and the spring 43 therein.

  The upper end of the spring 43 is attached to the lower surface 415 of the support bar 412. The spring 43 is attached to the base 44 at the lower end, and absorbs the energy of the abutting portion 41 that moves in the −z direction when the oscillator 11 is received. Thereby, when the oscillating body 11 abuts, the impact exerted by the oscillating body 11 on the abutting portion 41 is alleviated, and damage to the oscillating body 11 and the abutting portion 41 can be prevented. The base 44 has a flat plate shape, is placed on the ground E, and seals the lower side of the cylindrical portion 42.

  Returning to FIG. 1, the restriction rod 133 has a length of Lo in the vertical direction when the oscillating body 11 is not in contact. Here, Lo is slightly shorter than the height L1 from the ground to the lower surface 111 of the oscillating body 11 when the oscillating body 11 is positioned parallel to the ground E. For this reason, the regulating rod 133 comes into contact with the oscillating body 11 when the left end 112 of the oscillating body 11 moves slightly below the horizontal state.

  When the regulating rod 133 comes into contact with the rocking body 11, the contact portion 41 starts to move downward due to the energy of the rocking body 11, and the spring 43 starts to shrink. Then, the regulation rod 133 contracts until the length becomes L2. Here, L2 has a length such that the rocking angle of the rocking body 11 is −θ / 2.

  The restriction bar 134 is disposed at a position where the distance to the support bar 132 is equal to the distance from the restriction bar 133 to the support bar 132. Therefore, when the length of the regulating bar 134 is L2, the swing angle of the swing body 11 is −θ / 2. As a result, the oscillating body 11 oscillates within the range of the angle θ, with the oscillating angle in the range of −θ / 2 to + θ / 2.

  The lever portion 14 is provided on the left side of the left end 112 of the rocking body 11 and includes a lever bar 141, a support bar 142, and a hinge 143. The lever bar 141 is formed of an elongated bar. Here, the lever rod 141 is connected to the support rod 142 at a position 144 slightly to the right of the center. As a result, the lever bar 141 rotates in the pitch direction around the position 144 in the xz plane.

  A hinge 143 is attached to the upper surface of the right end of the lever bar 141. The lever bar 141 is connected to the lower surface 111 of the left end 112 of the oscillator 11 via a hinge 143. A motor 18 is attached to the left end of the lever bar 141.

  Accordingly, when the lever bar 141 receives a downward force from the motor 18, the lever bar 114 pulls the left end 112 of the oscillator 11 upward using the position 144 as a fulcrum.

  The support bar 142 is a bar that is placed on the ground E with a predetermined distance on the left side with respect to the regulation bar 133 and has a vertical direction as a longitudinal direction. The height of the position 144 from the ground E is substantially the same as the height of the support bar 132 from the ground E. Therefore, when the rocking body 11 is in a parallel state, the lever rod 141 is also in a parallel state with respect to the ground E.

  The lever portion 15 is provided on the right side of the restriction rod 134, has the same configuration as the lever portion 14, and includes a lever rod 151, a support rod 152, and a hinge 153. In other words, the lever rod 151 has the motor 19 attached to the right end and the left end connected to the right end 113 of the oscillator 11 via the hinge 153. When receiving a downward force from the motor 19, the right end 113 of the rocking body 11 is lifted upward with the position 154 as a fulcrum. By pulling up the rocking body 11 using the lever parts 14 and 15 in this way, the pulling force of the rocking body 11 by the motors 18 and 19 can be further reduced. As a result, low power motors 18 and 19 can be employed, and power consumption can be reduced.

  2 is a cross-sectional view in the width direction (yz plane) of the moving body 12 shown in FIG. FIG. 3 is a configuration diagram of the moving body 12 illustrated in FIG. 2 when viewed from the −y direction. As shown in FIG. 2, the moving body 12 includes a rotating body 21, a rotating shaft 22, a gear 23, a generator 24, a rotating shaft 25, and a housing 26. The rotating body 21 rotates based on the gravity component applied in the longitudinal direction of the oscillating body 11 when the oscillating body 11 is tilted, and moves the moving body 12 in the longitudinal direction of the oscillating body 11.

  The rotating shaft 22 is attached to the rotating body 21 through the center of the rotating body 21 with the y direction as the longitudinal direction. The rotating shaft 22 is attached to the side walls 261 and 261 via bearings (not shown). For this reason, the rotation shaft 22 is rotatably attached to the housing 26.

  The gear 23 includes a pinion gear 231 and an idler gear 232. The idler gear 232 has an end on the + y direction side of the rotary shaft 22 attached to the center. The pinion gear 231 is in mesh with the idler gear 232. The pinion gear 231 has the rotation shaft 25 passing through the center. Here, the gear ratio between the pinion gear 231 and the idler gear 232 is, for example, 1:10. Therefore, the angular velocity of the rotating shaft 25 is 10 times the angular velocity of the rotating shaft 22.

  The generator 24 has a disk shape and is attached to the rotating shaft 25 at the center. In the example of FIG. 2, two generators 24 are provided symmetrically with respect to the center of the rotating shaft 25, two at the + y direction end of the rotating shaft 25 and two at the −y direction end. Thereby, the rotating shaft 25 can rotate the four generators 24 with good balance. In the example of FIG. 2, the number of generators 24 is four. However, the number is not limited to this, and a plurality other than four (for example, eight) may be used.

  The rotating shaft 25 is parallel to the rotating shaft 22 and is attached to the upper side of the rotating shaft 22. The rotating shaft 25 passes through a pair of left and right support plates 27, 27 and is attached to the housing 26 by the pair of left and right support plates 27, 27. Each of the support plates 27 and 27 includes a bearing 28, and the rotary shaft 25 is rotatably attached via the bearing 28.

  The rotating shaft 25 passes through the side walls 261 and 261 on both sides of the housing 26. Each of the side walls 261 and 261 includes a bearing 29, and the rotary shaft 25 is rotatably attached via the bearing 29.

  The generator 24 generates power with the rotational force of the rotating body 21. Specifically, in the generator 24, the rotational force of the rotating body 21 is transmitted via the gear 23 and the rotating shaft 25, and the generator 24 receives the rotational force to generate power. FIG. 5 is a cross-sectional view showing a detailed structure of the generator 24 shown in FIG. The generator 24 includes a pair of magnet plates 241 and a coil plate 242 sandwiched between the pair of magnet plates 241.

  The magnet plate 241 has a disk shape and is radially divided into a plurality of regions, and regions where N-pole magnets are arranged and regions where S-pole magnets are arranged are alternately arranged. The coil plate 242 is provided with a plurality of regions in a radial manner like each region of the magnet plate 241, and a coil is arranged in each region. The magnet plates 241 and 241 rotate together with the rotary shaft 25, but the coil plate 242 is fixed to the housing 26. Therefore, as a result of the rotation of the rotating shaft 25 and the rotation of the magnet plate 241, the magnetic flux density linking each region of the coil plate 242 changes and electric power is generated.

  Returning to FIG. 2, the casing 26 includes an intermediate plate 262 whose longitudinal direction is the width direction at substantially the center in the vertical direction. The support plate 27 is attached between the middle plate 262 and the ceiling plate 263.

  A pulley 119 is attached to the lower end of each of the side walls 261 and 261. The pulley 119 has a rotating shaft 114 whose longitudinal direction is the vertical direction and a pair of wheels 115 and 115, and is attached to the side walls 261 and 261 so as to be rotatable about the rotating shaft 114 as a central axis.

  The oscillating body 11 has a groove 116 protruding downward in the yz plan view. The groove 116 stores the rotating body 21. A sheet-like convex portion 117 that comes into contact with the rotating body 21 is attached to the lower surface 111 of the oscillating body 11. The rotating body 21 moves the moving body 12 in the longitudinal direction of the oscillating body 11 by rolling the side surface of the rotating body 21 on the convex portion 117.

  The upper ends 116a and 116a of the groove part 116 are each provided with a guide part 118 extending in the + y direction side and the −y direction side. The guide portion 118 has a flat plate shape that is provided in almost the entire region in the longitudinal direction of the oscillator 11. The pulley 119 is attached so that the pair of wheels 115 sandwich the guide portion 118, and rotates along the guide portion 118. That is, the moving body 12 is attached to the rocking body 11 so as to sandwich the guide portion 118 from both sides via a pair of pulleys 119. Thereby, the mobile body 12 can move the rocking body 11 smoothly.

  FIG. 6 is a cross-sectional view (cross-sectional view of the xz plane) when the left end 112 of the oscillator 11 is cut at the center in the width direction. The left end 112 includes a contact portion 61, a spring 62, and a base 63. The base 63 is a cylindrical body erected in the longitudinal direction of the rocking body 11 from substantially the center of the side wall 64 at the left end 112. The movable body 12 side of the base 63 is opened, and the contact portion 61 is fitted. The contact portion 61 includes a receiving portion 611 that receives the moving body 12 and a support bar 612 that extends from the center of the receiving portion 611 toward the left end 112. The support bar 612 is embedded in the base 63. The spring 62 is attached between the base 63 and the contact portion 61. The spring 62 absorbs the energy of the contact portion 61 that moves toward the side wall 64 when receiving the moving body 12. Thereby, the impact which the mobile body 12 gives to the contact part 61 is relieved, and damage to the mobile body 12 and the contact part 61 can be prevented.

  As described above, the left end 112 of the oscillating body 11 includes the contact portion 61, the spring 62, and the base 63, and absorbs the impact of the moving body 12 when the moving body 12 reaches the left end 112 of the oscillating body 11. Since the absorbing mechanism is provided, it is possible to prevent the rocking body 11 and the moving body 12 from being damaged.

  Since the right end 113 also has the same absorption mechanism as the left end 112, the impact when the moving body 12 reaches the right end 113 of the oscillating body 11 is absorbed, and damage to the oscillating body 11 and the moving body 12 is prevented. Can do.

  Returning to FIG. 1, when the left end 112 of the oscillating body 11 reaches the lowest oscillating position, the motor 18 applies a restoring force to the oscillating body 11 via the lever rod 141 connected to the left end, and moves the left end 112 upward. Pull up in the direction. When the right end 113 of the oscillating body 11 reaches the lowest oscillating position, the motor 19 applies a restoring force to the oscillating body 11 via the lever rod 151 connected to the right end 113 and pulls the right end 113 upward. Here, the motors 18 and 19 are driven by using a part of the electric power generated by the generator 24 and apply a restoring force to the oscillator 11.

  The transmission unit 181 is configured by an elongated member (for example, a wire) connected between the motor 18 and the left end of the lever bar 141, and transmits the rotational force of the motor 18 to the lever bar 141. Similarly to the transmission unit 191, the transmission unit 191 transmits the rotational force of the motor 19 to the lever bar 151.

  The control unit 101 is configured by, for example, a microcomputer or a dedicated electric circuit, and controls operations of the motors 18 and 19. Specifically, when the left end 112 of the rocking body 11 is positioned at the lowest rocking position, the control unit 101 outputs a drive command to the motor 18 to drive the motor 18. As a result, the left end 112 is pulled upward. Then, when the left end 112 of the rocking body 11 moves to the uppermost rocking position, the control unit 101 stops driving the motor 18.

  When the left end 112 reaches the uppermost swing position, since the right end 113 is positioned at the lowermost swing position, the control unit 101 outputs a drive command to the motor 19 to drive the motor 19.

  As a result, the right end 113 is pulled upward. Then, when the right end 113 moves to the uppermost swing position, the control unit 101 stops driving the motor 19.

  Since the time Tα from when the left end 112 of the rocking body 11 reaches the lowest rocking position to when it reaches the uppermost rocking position can be calculated in advance by experiment, the control unit 101 uses the time Tα to calculate the motor 18. , 19 may be determined.

  Alternatively, a sensor that detects that the left end 112 of the oscillating body 11 has reached the lowermost oscillating position and a sensor that detects that the right end 113 of the oscillating body 11 has reached the lowest oscillating position are provided. 101 may determine the drive timing of the motors 18 and 19 according to the detection signals output from both sensors.

  The power storage unit 102 is configured by a chargeable / dischargeable secondary battery such as a lithium ion battery or an electric double layer capacitor, and is connected to the four generators 24 shown in FIG. 2 to store the power generated by the generator 24. .

  Next, the operation of the gravity power generator shown in FIG. 1 will be described. First, in the initial state, it is assumed that the left end 112 is located at the lowest swing position. The control unit 101 supplies electric power (for example, commercial power) to the motor 18 from the outside, and drives the motor 18.

  The rotational force of the motor 18 is transmitted to the oscillating body 11 via the transmission unit 181 and the lever bar 141. Thereby, the left end 112 of the rocking body 11 is pulled upward. When the rocking angle of the rocking body 11 turns negative and the rocking body 11 tilts obliquely to the lower right, the moving body 12 starts to move by receiving a gravity component in the longitudinal direction of the rocking body 11. Then, as the inclination of the oscillating body 11 on the lower right side increases, the moving body 12 also moves toward the right end 113 while increasing the speed. When the moving body 12 reaches the right end 113 and the left end 112 reaches the uppermost swing position, that is, when the time Tα has elapsed since the start of driving of the motor 18, the control unit 101 moves to the motor 18. Is cut off, and the drive of the motor 18 is stopped.

  When the left end 112 reaches the uppermost swing position, the control unit 101 drives the motor 19. The moving body 12 moves from the left end 112 to the right end 113 while the left end 112 moves from the lowest swing position to the highest swing position. Here, since the moving body 12 moves while rotating the rotating body 21, the rotating force of the rotating body 21 is applied to the generator 24 via the rotating shaft 22, the gear 23, and the rotating shaft 25 as shown in FIG. Then, the four generators 24 generate power. The electric power generated by the generator 24 is stored in the power storage unit 102. Therefore, the control unit 101 can drive the motor 19 using the electric power stored by the power storage unit 102.

  The rotational force of the motor 19 is transmitted to the oscillating body 11 via the transmission unit 191 and the lever rod 151. Thereby, the right end 113 of the rocking body 11 is pulled upward. When the rocking angle of the rocking body 11 turns positive and the rocking body 11 is tilted obliquely to the left, the moving body 12 receives a gravity component in the longitudinal direction of the rocking body 11 and starts moving. Then, as the inclination of the oscillating body 11 on the lower left side increases, the moving body 12 also moves toward the left end 112 while increasing the speed. When the moving body 12 reaches the left end 112 and the right end 113 reaches the uppermost swing position, that is, when the time Tα has elapsed since the start of driving of the motor 19, the control unit 101 moves to the motor 19. Is cut off, and the drive of the motor 19 is stopped.

  When the right end 113 reaches the uppermost swing position, the control unit 101 drives the motor 18 again. At this time, the control unit 101 drives the motor 18 using electric power stored by the power storage unit 102 instead of external power.

  As a result, the left end 112 starts to move from the lowest swing position to the highest swing position. Thereafter, the control unit 101 alternately drives the motors 18 and 19 for each time Tα, repeats the swinging of the swinging body 11, and stores the electric power generated when the moving body 12 moves the swinging body 11 in the power storage unit 102. Let

  Here, the inventor has found that the electric power generated while the moving body 12 moves from the left end 112 to the right end 113 or the electric power generated while the moving body 12 moves from the right end 113 to the left end 112 is generated by the motor 18 or 19. It has been found that the electric power required to move the left end 112 from the lowest swing position to the highest swing position is smaller than the power required for the above.

  Therefore, if the electric power generated by the generator 24 is stored in the power storage unit 102 and the motors 18 and 19 are driven by the electric power, the motors 18 and 19 are driven using a part of the electric power generated by the generator 24. And swinging of the swinging body 11 can be continued.

  FIG. 7 is an overall configuration diagram of a gravity power generation system including a plurality of gravity power generation apparatuses shown in FIG. The gravity power generation system includes n gravity power generation devices 71, 72,..., 7n (n is an integer of 2 or more), a control unit 701, and a power storage unit 702. Each of the gravity power generation devices 71 to 7n is configured by mechanical components other than the control unit 101 and the power storage unit 102 in the gravity power generation device illustrated in FIG. That is, the gravity power generation system shown in FIG. 7 has a plurality of mechanical components of the gravity power generation apparatus shown in FIG. Here, the gravity power generation devices 71 to 7n may be arranged in a single column, or may be arranged in a matrix with predetermined rows × predetermined columns.

  The control unit 701 drives the motors 18 and 19 of the gravity power generation devices 71 to 7n so that the oscillating body 11 of the gravity power generation devices 71 to 7n swings out of phase. Specifically, the control unit 701 alternately drives the motors 18 and 19 at time Tα in one gravity power generation device, and sets the movement start time of the motors 18 and 19 of the gravity power generation devices 71 to 7n to Tα / The motors 18 and 19 are driven by shifting by n.

  Thereby, even if a certain gravity power generation apparatus is not generating electric power, another gravity power generation apparatus will generate electric power, and a gravity power generation system can always be made into an electric power generation state. Therefore, when the motors 18 and 19 of a certain gravitational power generation apparatus are to be driven, a situation in which sufficient power is not stored in the power storage unit 702 can be avoided, and power generation can be stabilized.

  The power storage unit 702 includes a secondary battery such as a lithium ion battery or a battery double layer capacitor, and is connected to each of the generators 24 included in the gravity power generation devices 71 to 7n, and stores the power generated by each of the generators 24. .

(Embodiment 2)
Next, a gravity power generation apparatus according to Embodiment 2 of the present invention will be described. FIG. 8 is a side view of a gravity power generation device according to Embodiment 2 of the present invention.

  As shown in FIG. 8, the gravity power generation device includes a rocking body 910 (first rocking body), a rocking body 920 (second rocking body), moving bodies 930 and 970, and support portions 940 and 950.

  The support portion 940 includes a support plate 941, a support rod 942, and a rotation shaft 943. Similarly to the support portion 940, the support portion 950 also includes a support plate 951, a support rod 952, and a rotation shaft 953.

  The support bars 942 and 952 are bars erected in the vertical direction from the ground E. Rotating shafts 943 and 953 for rotatably supporting the support plates 941 and 951 are attached near the upper ends of the support rods 942 and 952, respectively.

  As shown in FIG. 12, the support plates 941 and 951 are constituted by flat plate members having a regular octagonal shape, for example, and rotary shafts 943 and 953 are attached to the respective centers O941 and O951. The shape of the support plates 941 and 951 is not limited to a regular octagon, and various shapes such as a circle, a quadrangle, and a triangle may be adopted. However, the balance of weight when the support plates 941 and 951 are rotated. From this point of view, a symmetric shape is preferable.

  The support plates 941 and 951 are attached to the rotating shafts 943 and 953 so that the normal direction orthogonal to the main surface is parallel to the direction orthogonal to the longitudinal direction of the support rods 942 and 952, The both ends of 920 are clamped. Here, the normal direction orthogonal to the main surface of the support plate 941 is described as the longitudinal direction D9 of the gravity power generation device.

  Specifically, the support plates 941 and 951 are configured such that when the left end 914 (an example of one end) of the swinging body 910 is positioned at the uppermost swing position H9, the right end 915 (an example of the other end) of the swinging body 910 swings to the bottom. It is attached to the both ends of the rocking | swiveling body 910 so that it may be located in the moving position L9.

  Further, when the right end 925 (an example of the other end) of the rocking body 920 is positioned at the uppermost rocking position H9, the left end 924 (an example of one end) of the rocking body 920 is the lowermost rocking position L9. Are attached to both ends of the rocking body 920 so as to be positioned at the center.

  Further, the support plates 941 and 951 have both ends of the rocking bodies 910 and 920 so that when the left end 914 of the rocking body 910 is located at the uppermost rocking position H9, the right end 925 of the rocking body 920 is located at the uppermost rocking position H9. Is attached.

  FIG. 12 is a schematic diagram showing the positional relationship between the support plates 941 and 951 and the rocking bodies 910 and 920. FIG. 12 shows a state where the left end 914 of the rocking body 910 is located at the lowest rocking position L9 and the right end 925 of the rocking body 920 is located at the bottom rocking position L9. As shown in FIG. 12, the support plates 941 and 951 are arranged with a certain interval in the longitudinal direction D9 so that the shapes overlap when viewed from the longitudinal direction D9.

  The oscillators 910 and 920 are attached to the support plates 941 and 951 so as to be parallel to the longitudinal direction D9 when viewed from above.

  Specifically, the rocking body 910 is attached to the support plate 941 so that the left end 914 is positioned on the left side of the side 941a of the support plate 941. The rocking body 920 is attached to the support plate 941 so that the left end 924 is positioned on the right side of the side 941b of the support plate 941 (side facing the side 941a).

  The left ends 914 and 924 are attached to the support plate 941 so as to be point-symmetric with respect to the center O941 at a certain distance R9 from the center O941 of the support plate 941.

  Further, the oscillator 910 is attached to the support plate 951 so that the right end 915 is positioned on the left side of the side 951b of the support plate 951 (side parallel to the side 941b). The swing body 920 is attached to the support plate 951 so that the right end 925 is positioned on the right side of the side 951a of the support plate 951 (the side facing the side 951b).

  The right ends 915 and 925 are attached to the support plate 951 so as to be spaced apart from the center O951 of the support plate 951 by a certain distance R9 and to be point-symmetric about the center O951.

  Returning to FIG. 8, the rocking body 910 includes a first rail portion 911 and a second rail portion 912 that sandwich the rotating body 932 having a disk shape from the direction of the circumferential surface of the rotating body 932. The first rail portion 911 has a convex sectional shape with a flat top surface, and the second rail portion 912 has a convex sectional shape with a flat bottom surface. The inner wall on the top surface of the first rail portion 911 and the inner wall on the bottom surface of the second rail portion 912 are in contact with the circumferential surface of the rotating body 932. Accordingly, the rotating body 932 can be moved along the first rail portion 911 and the second rail portion 912 like a wheel.

  The first rail portion 911 and the second rail portion 912 are provided with a gap D11, and the roller 931 of the moving body 930 is sandwiched in the gap D11. Thereby, the moving body 930 can move along the longitudinal direction of the rocking body 910. That is, the gap D11 serves as a guide part for guiding the movement of the moving body 930 in the longitudinal direction, and the roller 931 functions as a pulley that moves along the guide part. Further, the inside of the first rail portion 911 and the second rail portion 912 serves as a moving path of the moving body 930.

  In the state of FIG. 8, the left end 914 of the swinging body 910 is positioned at the uppermost swing position H9, and the right end 915 of the swinging body 910 is positioned at the lowest swing position L9. Located on the upper side, the second rail portion 912 is positioned on the lower side.

  However, when the left end 914 of the oscillating body 910 is located at the lowest oscillating position L9 and the right end 915 of the oscillating body 910 is located at the uppermost oscillating position H9, the first rail portion 911 is located on the lower side, The two rail portions 912 are located on the upper side and are turned upside down.

  As shown in FIG. 12, the left end 914 of the rocking body 910 located at the lowest rocking position L9 is pulled up to the uppermost rocking position H9 as the support plate 941 rotates counterclockwise. This is because the top and bottom of the oscillator 910 are inverted at this time.

  Therefore, for example, when the rocking body 910 is configured by only the first rail portion 911 or the second rail portion 912, the first rail portion 911 or the second rail portion 912 that is on the lower side with the rocking body 910 turned upside down is inverted. , The rotating body 932 comes off from the first rail part 911 or the second rail part 912 and falls off.

  Therefore, in the present embodiment, as shown in FIG. 8, the rocking body 910 is configured such that the first rail portion 911 and the second rail portion 912 sandwich the rotating body 932 from the circumferential surface side. . Thereby, even if the top and bottom of the first rail portion 911 and the second rail portion 912 are inverted, it is possible to prevent the rotating body 923 from dropping from the first rail portion 911 and the second rail portion 912.

  Note that the first rail portion 921 and the second rail portion 922 constituting the swing body 920 also have a case where the left end 924 is positioned at the uppermost swing position H9 due to the rotation of the support plate 941 and the left end 924 is similar to the swing body 910. The upper and lower sides are reversed when positioned at the lowest swing position L9. However, similarly to the oscillating body 910, the oscillating body 920 is configured such that the pair of upper and lower first rail portions 921 and the second rail portion 922 sandwich the rotating body 972 from the circumferential surface side. Therefore, even if the swinging body 920 is turned upside down, the rotating body 972 can be prevented from falling off from the swinging body 920.

  In the example of FIG. 8, two rollers 931 are arranged on the left side around the rotating body 932, and two rollers 931 are arranged on the right side of the rotating body 932. Of the two rollers 931 arranged on the left side, the upper roller 931 is in contact with the first rail portion 911 and the lower roller 931, and the lower roller 931 is in contact with the second rail portion 912. In addition, the two rollers 931 disposed on the right side of the rotating body 932 are also disposed in the gap D11 in the same manner as the roller 931 disposed on the left side. Accordingly, the four rollers 931 can move stably and smoothly in the gap D11, and the moving body 930 can move the rocking body 910 stably and smoothly.

  Similar to the moving body 930, the moving body 970 includes two rollers 971 on the left and right sides around the rotating body 972. The rocking body 920 sandwiches the roller 971 of the moving body 970 in the gap D11 between the first rail portion 921 and the second rail portion 922, like the rocking body 910. Thereby, the moving body 970 can move along the longitudinal direction of the rocking body 920.

  The moving body 930 includes a generator 933 and a pulley 934 in addition to the roller 931 and the rotating body 932. The rotating body 932 is sandwiched between the first rail portion 911 and the second rail portion 912, and is rotatably supported by the housing 937. In other words, the rotating body 932, like the rotating body 21 shown in FIG. 2, moves in response to the gravitational component in the longitudinal direction of the swinging body 910 and rotates with the movement. Slip. The rotation of the rotating body 932 is transmitted to the generator 933 via the pulley 934, and the generator 933 generates power.

  One generator 933 is provided above the rotating body 932, and two generators 933 are provided below the rotating body 932. By providing the plurality of generators 933 as described above, the power generation efficiency is improved. Since the moving body 970 has the same configuration as that of the moving body 930, description thereof is omitted.

  Grooves are provided on the outer periphery of the support plates 941 and 951, and chains 960 and 980 for transmitting the rotational force from the motors 990 and 991 to the support plates 941 and 951 are wound around the grooves. Specifically, the chain 960 is an endless chain stretched by a support plate 941 and a pulley (not shown) of the motor 990. The chain 980 is also stretched by the support plate 951 and the pulley of the motor 991.

  The control unit 1001 is configured by, for example, a microcomputer or a dedicated electric circuit, and controls the operation of the motors 990 and 991.

  Specifically, the control unit 1001 outputs a drive command to the motors 990 and 991 when the left end 914 of the swing body 910 and the right end 925 of the swing body 920 are positioned at the lowest swing position L9, and the motors 990 and 991 are output. Drive.

  As a result, both the support plates 941 and 951 rotate in the same direction, and the moving bodies 930 and 970 are raised toward the uppermost swing position H9 while the swinging bodies 910 and 920 rotate together with the rotation.

  When the movable bodies 930 and 970 reach the uppermost swing position H9, the movable bodies 930 and 970 move toward the lowest swing position L9 along the longitudinal direction of the swing bodies 910 and 920. Thereby, the rotating bodies 932 and 972 rotate, and the generators 933 and 973 generate power. The generated power is stored in the power storage unit 1002.

  When the moving bodies 930 and 970 reach the lowest swing position L9, the motors 990 and 991 are driven again to rotate the support plates 941 and 951, so that the mobile bodies 930 and 970 are moved to the highest swing position H9. lift. By repeating the above, power is stored in the power storage unit 1002.

  Returning to FIG. 8, the stoppers 916, 917, 926, and 927 prevent the moving bodies 930 and 970 from sliding along the swinging bodies 910 and 920 during the rotation of the support plates 941 and 951.

  FIG. 13 is a view showing a detailed structure of the stopper 927. The stopper 927 includes a frame 927a, a spring 927b (elastic body), and a protrusion 927c. The frame 927a is provided to protrude downward on the lower surface of the swinging body 920 before the right end 925.

  The lower end of a shaft portion 927e provided on the lower side of the projection 927c is connected to the bottom surface 927d of the frame 927a. A hole is formed in the lower surface of the rocking body 920, and a protrusion 927c is provided in the hole so as to be able to appear and retract. A spring 927b is provided between the lower surface 927f and the bottom surface 927d of the protrusion 927c so as to surround the shaft portion 927e. The protrusion 927c is urged by a spring 927b in a direction (direction D14) perpendicular to the lower surface of the rocking body 920. As a result, the protrusion 927c can freely appear and disappear on the lower surface of the rocking body 920.

  The elastic coefficient of the spring 927b has such a value that when the rotating body 972 reaches the uppermost swing position H9, the entire area of the protrusion 927c is buried in the lower surface of the swinging body 920 by the force that the rotating body 972 tries to roll.

  Therefore, the stopper 927 operates as follows. i) When the rotating body 972 reaches the uppermost swing position H9, the rotating body 972 is pushed down by its own weight. ii) When the rotating body 972 reaches the lowest swinging position L9, it appears and disappears from the lower surface of the swinging body 920. iii) After the support plate 941 starts rotating, the state where the support plate 941 protrudes from the lower surface of the rocking body 920 is maintained until the rotating body 972 reaches the uppermost rocking position H9. iv) When the rotating body 972 reaches the uppermost swing position H9, it is buried in the lower surface of the swing body 920.

  When the rotary body 972 reaches the lowest swing position L9, the rotary body 972 is lifted to the highest swing position H9 by the rotation of the support plate 951, but when the support plate 951 rotates 90 degrees or more, the rotary body 972. Is higher than the center O951 of the support plate 951, so the rotating body 972 tends to roll along the rocking body 920.

  However, at this time, the protrusion 927c of the stopper 927 protrudes and descends from the lower surface of the swinging body 920 to prevent the rotating body 972 from rolling. Therefore, after waiting for the rotating body 972 to be lifted to the uppermost swing position H9, it can move toward the lowermost swing position L9. As a result, the rotating body 972 is prevented from starting moving before reaching the uppermost swing position H9, and the rotating body 972 can be dropped from a higher position, and more electric power can be generated. .

  The stopper 916 shown in FIG. 8 is the same as the stopper 927 except that the stopper 916 is provided at the left end 914 of the swinging body 910, and thus the description thereof is omitted. The stopper 917 is the same as the stopper 927 except that it is provided on the upper surface of the rocking body 920 at the right end 915 of the rocking body 910, and the description thereof will be omitted. The stopper 926 is the same as the stopper 927 except that the stopper 926 is provided on the upper surface of the rocking body 910 at the left end 924 of the rocking body 920, and thus the description thereof is omitted.

  Returning to FIG. 8, the cushion 918 is provided at both ends of the rocking body 910, and the cushion 928 is provided at both ends of the rocking body 920. When the moving bodies 930 and 970 reach the lowest rocking position L9, the rotating bodies 932 and 972 Absorbs shock. Since the cushions 918 and 928 have the same configuration, only the cushion 918 will be described. The cushion 918 includes a leg portion 918a, a ceiling portion 918b, and an absorber 918c. A total of four leg portions 918a are provided in the vertical direction so as to surround the rocking body 910 along the side wall of the rocking body 910 from the support plate 951 in the longitudinal direction D9.

  The ceiling portion 918b is a bar-like member provided so as to connect the tips of the pair of upper and lower leg portions 918a, 918a. The pair of upper and lower leg portions 918a and 918a on the back side of the drawing is attached with a ceiling portion 918b in the same manner as the front leg portions 918a and 918a.

  There are a pair of ceiling portions 918b across the side wall of the rocking body 910. In the vicinity of the center of the ceiling portions 918b and 918b, an absorber 918c is provided in the depth direction so as to connect the ceiling portions 918b and 918b, that is, in a direction orthogonal to the moving path of the moving body 930.

  The absorber 918c is made of, for example, a belt-like stretchable elastic member (for example, rubber). The absorber 918c receives the moving body 930 that has rolled along the rocking body 910. Specifically, the absorber 918c absorbs the impact of the moving body 930 by bending in the moving direction of the moving body 930 when it contacts the moving direction side wall of the housing 937 covering the moving body 930. . Here, the strength, length, and width (thickness) of the absorber 918c are adjusted to values such that the wall on the traveling direction side of the moving body 930 does not contact the support plate 951.

  Thereby, when the moving body 930 reaches the lowest swing position L9, the collision between the moving body 930 and the support plate 951 can be avoided, and damage to both members can be prevented.

  FIG. 9 is a sequence diagram showing how the moving bodies 930 and 970 move in a side view of the gravity power generator according to Embodiment 2 of the present invention. In FIG. 9, time has passed toward (A) to (D).

  In FIG. 9A, the moving bodies 930 and 970 are located at the uppermost swing position H9. When the moving bodies 930 and 970 reach the uppermost swing position H9, the stoppers 916 and 927 are buried, and the moving bodies 930 and 970 start moving toward the lowermost swing position L9.

  In FIG. 9B, the moving bodies 930 and 970 are located at the lowest swing position L9. When the moving bodies 930 and 970 are positioned at the lowest swing position L9, the support plates 941 and 951 start to rotate. When the support plates 941 and 951 are rotated 180 degrees, the moving bodies 930 and 970 are lifted to the uppermost swing position H9. While the support plates 941 and 951 are rotating, since the stoppers 926 and 917 are projected and retracted, the movement of the moving bodies 930 and 970 is restricted.

  In FIG. 9C, the moving bodies 930 and 970 are located at the uppermost swing position H9. When the moving bodies 930 and 970 reach the uppermost swing position H9, the stoppers 926 and 917 are buried, and the moving bodies 930 and 970 start moving along the swing bodies 910 and 920.

  Then, as shown in FIG. 9D, the moving bodies 930 and 970 reach the lowest swing position L9. Then, the support plates 941 and 951 start to rotate, and the moving bodies 930 and 970 are lifted to the uppermost swing position H9. The sequence shown in FIGS. 9A to 9D is repeated, and the generation of power is continued.

  FIG. 10 is a sequence diagram showing how the moving bodies 930 and 970 move when the support plate 951 is viewed from the support plate 941 in the longitudinal direction D9. In FIG. 10, time has passed toward (A) to (J).

  In FIG. 10A, both the moving bodies 930 and 970 are located at the lowest swing position L9. In FIG. 10A, the moving body 930 is located on the support plate 941 side, and the moving body 970 is located on the support plate 951 side. Therefore, in FIG. 10A, the moving body 930 is indicated by a solid line, and the moving body 970 is indicated by a dotted line.

  In FIG. 10A, the control unit 1001 drives the motors 990 and 991 to rotate the support plates 941 and 951 counterclockwise.

  In FIG. 10B, the support plates 941 and 951 are rotated 45 degrees counterclockwise. Thereafter, as the support plates 941 and 951 and the support plates 941 and 951 rotate by 45 degrees counterclockwise, the moving bodies 930 and 970 rotate and the position gradually rises.
