[0007] In the present invention, more preferably, a torsion spring is also fitted and connected to the connection between the first prong and the U-shaped frame through a card slot.

[0008] In the present invention, more preferably, the first ratchet, the third ratchet and the second ratchet have the same direction of the barbed teeth, and the inner wall diameter of the first synchronizing ring is larger than the diameter of the rotary connecting shaft.

[0009] More preferably, in the present invention, the extending oscillating member includes a connecting box attached to the top of the mount below the transmission shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By providing a unidirectional rotating member, when the transmission shaft rotates the large bevel gear disc clockwise, the large bevel gear disc rotates and drives the third ratchet. At this time, the second barbed pawl does not perform a limiting function on the second ratchet, and the rotary connecting shaft rotates counterclockwise following the third ratchet. On the other hand, when the transmission shaft rotates the large bevel gear disc counterclockwise, the second transmission bevel gear drives the rotary connecting shaft to rotate counterclockwise, and at the same time, the third barbed pawl oscillates back and forth along the third ratchet. As a result, during the reciprocating rotation of the transmission shaft, the rotary connecting shaft always rotates in the same direction, driving the generator to operate. As a result, wave utilization efficiency is improved and power generation efficiency is enhanced.

[0016] 2. The extended swinging member rotates the turntable when the extension rod swings, and the turntable raises or lowers the straight-groove connecting rail via the card pin. When the straight-groove connecting rail moves downward relative to the connecting box, the hydraulic pressure block presses on the aqueous solution inside the connecting box, causing the piston rod to swing the swinging rod and rotate the transmission shaft relative to the U-shaped frame. Similarly, when the extension rod returns to its original position, the elastic return force of the return spring drives the piston rod to press on the aqueous solution inside the sleeve, forcing it into the connecting box. At the same time, the small cross-sectional area of ​​the bottom of the sleeve increases the swinging width of the swinging rod, allowing power to be supplied to the generator. This further improves power generation efficiency. [Brief explanation of the drawings]

Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0021] The following describes an embodiment of the present invention based on its overall structure.

[0022] 1 to 8, one embodiment of the present invention shows a wave power generation device comprising a mounting base 1. A first support frame 2 is attached to the top of the mounting base 1, and a U-shaped frame 3 is attached to the top of the first support frame 2. A transmission shaft 4 is rotatably connected to the inside of the U-shaped frame 3 and extends to the outside of the U-shaped frame 3. A second support frame 15 is attached to the top of the mounting base 1, located on one side of the first support frame 2. A generator 7 is attached to the top of the second support frame 15, and a co-rotating member located inside the U-shaped frame 3 is attached to one end of the transmission shaft 4, and the transmission shaft 4 is connected to the generator 7 via the co-rotating member. A swinging member is attached to one end of the transmission shaft 4, located outside the U-shaped frame 3, and the transmission shaft 4 is connected to an extension rod 8 via the swinging member. A sleeve 9 is attached to one end of the extension rod 8, and a ball shaft link 10 is fitted to the bottom of the sleeve 9. A rotation block 12 is rotatably connected to the bottom end of the spherical shaft link 10, a floating block 13 is attached to the bottom of the rotation block 12, and a flow prevention plate 14 is provided at the bottom of the floating block 13.

[0023] In this embodiment, the mounting base 1 is attached to the shore, and the baffle plate 14 is submerged in seawater. The floating block 13 floats on the water's surface. When waves strike the baffle plate 14, the shaft sleeve 9 and the ball-and-socket link 10 work together to change the orientation of the side of the baffle plate 14 so that the side of the baffle plate 14 faces the waves. This allows the waves to strike one side of the baffle plate 14. At the same time, the floating block 13 moves up and down with the impact of the waves, causing the extension rod 8 to swing up and down. During this process, the extending swing member rotates the transmission shaft 4 by a large amount, causing the transmission shaft 4 to rotate back and forth. As the transmission shaft 4 rotates relative to the U-shaped frame 3, the co-rotating member operates to supply continuous power to the generator 7, which then generates electricity.

[0024] 1, 2, 3, 4, and 5, the same-direction rotating member includes a large bevel gear disk 501 attached to one end of the transmission shaft 4 inside the U-shaped frame 3. A rotary connecting shaft 502 is rotatably connected to the inside of the U-shaped frame 3, and one end of the rotary connecting shaft 502 extends to the outside of the U-shaped frame 3 to connect with the generator 7. A first transmission bevel gear 505 and a second transmission bevel gear 506 are rotatably connected to the rotary connecting shaft 502 via bearings, and the first transmission bevel gear 505 and the second transmission bevel gear 506 are arranged symmetrically along the vertical center axis of the large bevel gear disk 501, and both mesh with the large bevel gear disk 501. A second synchronizer ring 511 is attached to the side of the first transmission bevel gear 505 closer to the generator 7, and a third barbed claw 509 is rotatably connected to the side of the second synchronizer ring 511 remote from the first transmission bevel gear 505. A torsion spring 513 is fitted and connected to the connecting portion between the third barbed claw 509 and the second synchronizer ring 511 via a card slot, and a third ratchet 512 that meshes with the third barbed claw 509 is fixed to the outside of the rotary connecting shaft 502. A first synchronizer ring 510 is attached to the side of the second transmission bevel gear 506 remote from the first transmission bevel gear 505, and a second barbed claw 507 is connected to the side of the first synchronizer ring 510 remote from the second transmission bevel gear 506. A torsion spring 513 is also fitted and connected to the connecting portion between the second barbed claw 507 and the first synchronizer ring 510, and a second ratchet 508 that meshes with the second barbed claw 507 is fixed to the rotary connecting shaft 502. A first prong 504 is connected to the top of the U-shaped base 3 , and a first ratchet 503 located outside the U-shaped base 3 is fixed to the rotary connecting shaft 502 .

[0025] In this embodiment, when the transmission shaft 4 rotates, it rotates the first transmission bevel gear 505 and the second transmission bevel gear 506 in opposite directions via the large bevel gear disk 501. When the transmission shaft 4 rotates the large bevel gear disk 501 clockwise, the large bevel gear disk 501 rotates the third ratchet 512 via the first transmission bevel gear 505, the second synchronizer ring 511, and the third barbed pawl 509. At this time, the second transmission bevel gear 506 rotates the second barbed pawl 507, but the second barbed pawl 507 cannot exert a position limiting function on the second ratchet 508. Instead, the second transmission bevel gear 506 oscillates back and forth due to the action of the torsion spring 513. As a result, the rotary connecting shaft 502 rotates counterclockwise following the third ratchet 512. On the other hand, when the transmission shaft 4 rotates the large bevel gear disk 501 counterclockwise, the second transmission bevel gear 506 drives the rotary connecting shaft 502 to rotate counterclockwise via the first synchronizer ring 510, the second barbed claw 507, and the second ratchet 508, and at the same time, the third barbed claw 509 oscillates back and forth along the third ratchet 512. As a result, while the transmission shaft 4 rotates back and forth, the rotary connecting shaft 502 always continues to rotate in the same direction, driving the generator 7 to operate. As a result, wave utilization efficiency is improved, and power generation efficiency is increased.

[0026] Referring mainly to FIGS. 3 and 5, a torsion spring 513 is also fitted and connected to the connecting portion between the first prong 504 and the U-shaped base 3 via a card slot.

[0027] In this embodiment, by providing this structure, the first barbed claw 504 restricts the one-way rotation of the first ratchet 503, allowing the rotating connecting shaft 502 to rotate in only one direction, thereby further improving the rotational stability of the rotating connecting shaft 502.

[0028] 3, 4 and 5, the orientation of the barbed teeth in the first ratchet 503, the third ratchet 512 and the second ratchet 508 is the same, and the inner wall diameter of the first synchronizing ring 510 is larger than the diameter of the rotary connecting shaft 502.

[0029] In this embodiment, this structure prevents the second barbed pawl 507 and the third barbed pawl 509 from simultaneously restricting their positions relative to the second ratchet 508 and the third ratchet 512 when the large bevel gear disk 501 drives the first transmission bevel gear 505 and the second transmission bevel gear 506 to rotate. This allows the rotary connecting shaft 502 to rotate in one direction and also prevents friction from occurring between the rotary connecting shaft 502 and the first synchronizer ring 510 when the rotary connecting shaft 502 rotates.

[0030] 1, 2, 6, 7 and 8, the extending oscillating member includes a connection box 601 attached to the top of the mounting base 1 and located below the transmission shaft 4. A guide pipe 612 is connected to one side of the connection box 601, and a sleeve 602 connected to the mounting base 1 is attached to one end of the guide pipe 612. A piston rod 611 extending to the top of the sleeve 602 is inserted inside the sleeve 602, and a push frame 609 located above the sleeve 602 is attached to the top of the piston rod 611. A swing rod 603 is attached to one end of the transmission shaft 4 remote from the large bevel gear disk 501, and guide grooves 607 are opened on both sides of the swing rod 603. A shift pin 608 slidably connected to the guide groove 607 is attached to the inside of the push frame 609, and return springs 606 connected to the top of the mounting base 1 are provided on both sides of the push frame 609. A side connecting frame 605 is attached to the outside of the U-shaped frame 3, and a turntable 604 is rotatably connected to one end of the side connecting frame 605. An extension rod 8 is attached to the outer wall of the turntable 604, and a card pin 614 is attached to the inside of the turntable 604. A straight-groove connecting rail 615 is fitted onto the card pin 614, and an insertion rod 610 is attached to the outer wall of the straight-groove connecting rail 615, extending to the inside of the connection box 601. A hydraulic pressure hold-down block 613 located inside the connection box 601 is attached to the bottom end of the insertion rod 610.

[0031] In this embodiment, when the extension rod 8 swings, the turntable 604 is driven to rotate. At this time, the turntable 604 moves the straight-grooved connecting rail 615 upward or downward via the card pin 614. When the straight-grooved connecting rail 615 moves downward relative to the connection box 601, the hydraulic pressure holding block 613 presses the aqueous solution inside the connection box 601. At this time, the aqueous solution inside the connection box 601 flows into the sleeve 602 via the inlet pipe 612, thereby lifting the piston rod 611. When the piston rod 611 lifts, the swing rod 603 is driven to swing via the push frame 609, the guide groove 607, and the shift pin 608, thereby rotating the transmission shaft 4 relative to the U-shaped frame 3. Similarly, when the extension rod 8 returns to its original position, the return spring 606 acts with an elastic restoring force to drive the piston rod 611, pressing the aqueous solution inside the sleeve 602, causing the aqueous solution inside the sleeve 602 to flow into the connection box 601. At the same time, the cross-sectional area of ​​the bottom of the sleeve 602 is small, so that the swing width of the swing rod 603 increases, which makes it possible to supply power to the generator 7 and further improve the power generation efficiency.

[0032] Referring to FIG. 8, the card pin 614 and the rotating disk 604 are not aligned with each other, and the inner width of the straight groove connecting rail 615 is equal to the diameter of the card pin 614 .

[0033] In this embodiment, by providing this structure, when the turntable 604 rotates, the card pin 614 drives the straight groove connecting rail 615 to move, thereby causing the hydraulic pressure pressing block 613 to press the aqueous solution inside the connection box 601.

[0034] Referring primarily to FIG. 7, the cross-sectional area of ​​the bottom of the sleeve 602 is smaller than the cross-sectional area of ​​the bottom of the connection box 601 .

[0035] In this embodiment, by providing this structure, when the hydraulic pressure holding block 613 moves, the movement distance of the piston rod 611 is made larger than the movement distance of the hydraulic pressure holding block 613, thereby increasing the swing range of the swing rod 603.

[0036] Referring mainly to FIG. 6, the diameter of the shift pin 608 is equal to the width of the guide groove 607, and the swing rod 603 and the transmission shaft 4 are connected in an L-shape.

[0037] In this embodiment, by providing this structure, when the piston rod 611 moves up and down, the push base 609 drives the swing rod 603 to swing via the shift pin 608 and the guide groove 607, thereby causing the transmission shaft 4 to rotate back and forth. At the same time, because one end of the swing rod 603 is located away from the center of the transmission shaft 4, the swing rod 603 and the transmission shaft 4 form a leverage structure at this point, which saves force. This reduces the force required to rotate the transmission shaft 4.

[0038] Referring mainly to FIG. 7, both ends of the flow guide pipe 612 extend into the connection box 601 and the sleeve 602, respectively.

[0039] In this embodiment, this structure ensures that the inlet pipe 612 is always positioned below the hydraulic pressure hold-down block 613 when the hydraulic pressure hold-down block 613 moves. At the same time, the hydraulic pressure hold-down block 613 and the piston rod 611 can be confined via the portions where both ends of the inlet pipe 612 extend into the connection box 601 and the sleeve 602, preventing the hydraulic pressure hold-down block 613 and the piston rod 611 from moving to a position where they are flush with the inlet pipe 612.

[0040] The following is a wave power generation method based on the above-described wave power generation device, The mounting base 1 is attached to the shore, and the flow prevention plate 14 is immersed in seawater. At this time, the floating block 13 floats on the water surface. When waves impact the flow prevention plate 14, the axis sleeve 9 and the spherical axis connecting rod 10 work together to change the orientation of the side of the flow prevention plate 14, so that the side of the flow prevention plate 14 faces the waves. Step and; When the wave impacts one side of the flow prevention plate 14, the floating block 13 moves up and down once due to the impact of the wave, which causes the extension rod 8 to swing up and down. When the extension rod 8 swings, the turntable 604 is driven to rotate. At this time, the turntable 604 moves the straight-grooved connecting rail 615 upward or downward via the card pin 614. When the straight-grooved connecting rail 615 moves downward relative to the connection box 601, the hydraulic pressure holding block 613 presses the aqueous solution inside the connection box 601. At this time, the aqueous solution inside the connection box 601 flows into the sleeve 602 via the inlet pipe 612, causing the piston rod 611 to rise. When the piston rod 611 rises, the swing rod 603 is driven to swing via the push frame 609, the guide groove 607, and the shift pin 608, causing the transmission shaft 4 to rotate relative to the U-shaped frame 3. Similarly, when the extension rod 8 returns to its original position, the return spring 606 acts with an elastic restoring force to drive the piston rod 611 and press the aqueous solution inside the sleeve 602, causing the aqueous solution inside the sleeve 602 to flow into the connection box 601. At the same time, since the cross-sectional area of ​​the bottom of the sleeve 602 is small, the swing width of the swing rod 603 increases, which causes the transmission shaft 4 to rotate more widely. When the transmission shaft 4 rotates, it rotates the first transmission bevel gear 505 and the second transmission bevel gear 506 in opposite directions via the large bevel gear disk 501. When the transmission shaft 4 rotates the large bevel gear disk 501 clockwise, the large bevel gear disk 501 rotates the third ratchet 512 via the first transmission bevel gear 505, the second synchronizer ring 511, and the third barbed pawl 509. At this time, the second transmission bevel gear 506 rotates the second barbed pawl 507. However, at this time, the second barbed pawl 507 cannot perform a position limiting function on the second ratchet 508, so the second barbed pawl 507 oscillates back and forth due to the action of the torsion spring 513 as the second transmission bevel gear 506 rotates. As a result, the rotary connecting shaft 502 rotates counterclockwise along with the third ratchet 512. When the transmission shaft 4 rotates the large bevel gear disk 501 counterclockwise, the second transmission bevel gear 506 rotates the rotary connecting shaft 502 counterclockwise via the first synchronization ring 510, the second barbed claw 507, and the second ratchet 508. At the same time, the third barbed claw 509 oscillates back and forth along the third ratchet 512. As a result, when the transmission shaft 4 rotates back and forth, the rotary connecting shaft 502 always rotates in the same direction, thereby operating the generator 7. As a result, the utilization rate of waves is improved and power generation efficiency is increased. Includes:
