[0014] The present invention also discloses a sea wave power generation method, which uses the above-mentioned sea wave power generation device and comprises the following steps:

[0015] S1: The mounting base is installed on the shore so that the spoiler is immersed in the sea water. At this time, the floating block floats on the water surface. When the waves impact the spoiler, the side direction of the spoiler is changed by the cooperation of the shaft sleeve and the ball shaft connecting rod, so that the side of the spoiler faces the waves.

[0016] S2: In this way, the waves can impact one side of the spoiler, and the floating block will move up and down with the impact of the waves, so that the extension rod can swing up and down;

[0017] S3: The transmission shaft is rotated greatly by the distance increasing positioning member, and the transmission shaft is reciprocatingly rotated at this time;

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting a co-rotating member, when the transmission shaft drives the large bevel gear disc to rotate clockwise, the large bevel gear disc will drive the third ratchet to rotate. At this time, the second ratchet pawl cannot limit the second ratchet, so that the rotating shaft can rotate counterclockwise with the third ratchet. When the transmission shaft drives the large bevel gear disc to rotate counterclockwise, the second transmission bevel gear drives the rotating shaft to rotate counterclockwise. At the same time, the third ratchet pawl will reciprocate along the third ratchet. In this way, when the transmission shaft reciprocates, the rotating shaft always rotates in the same direction, thereby driving the generator to operate, thereby improving the utilization rate of waves and improving power generation efficiency;

[0021] 2. By setting the distance-increasing swing part, when the extension rod swings, it will drive the indexing plate to rotate. At this time, the indexing plate drives the straight groove connecting rail to move upward or downward through the bayonet. When the straight groove connecting rail moves downward relative to the connecting box, the liquid pressure plug will squeeze the aqueous solution inside the connecting box. At this time, the piston rod drives the swing rod to swing, so as to rotate the transmission shaft relative to the U-shaped frame. Similarly, when the extension rod is restored, the reset spring will drive the piston rod to press the aqueous solution inside the sleeve under the action of the elastic restoring force, so as to make the aqueous solution inside the sleeve enter the connecting box. At the same time, due to the small cross-sectional area of ​​the bottom of the sleeve, this will cause the swing amplitude of the swing rod to increase, which can provide power for the generator and further improve the power generation efficiency.

The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0034] In this embodiment: the mounting base 1 is installed on the shore so that the spoiler 14 is immersed in the sea water. At this time, the floating block 13 floats on the water surface. When the waves impact the spoiler 14, the side orientation of the spoiler 14 is changed by the cooperation of the shaft sleeve 9 and the ball-shaft connecting rod 10, so that the side of the spoiler 14 faces the waves. In this way, the waves can impact one side of the spoiler 14. At the same time, the floating block 13 will move up and down with the impact of the waves, so as to make the extension rod 8 swing up and down. In this process, the transmission shaft 4 is rotated significantly through the distance-increasing swing member. At this time, the transmission shaft 4 reciprocates. When the transmission shaft 4 rotates relative to the U-shaped frame 3, the operation of the same-direction rotating member is used to provide continuous power to the generator 7, and the power generation effect is achieved through the operation of the generator 7.

[0035] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The co-rotating member includes a large bevel gear plate 501 installed at one end of the transmission shaft 4 and located on the inner side of the U-shaped frame 3. The inner side of the U-shaped frame 3 is rotatably connected with a rotating coupling 502. One end of the rotating coupling 502 extends to the outer side of the U-shaped frame 3 and is connected to the generator 7. The rotating coupling 502 is rotatably connected with a first transmission bevel gear 505 and a second transmission bevel gear 506 through a bearing. The first transmission bevel gear 505 and the second transmission bevel gear 506 are symmetrically arranged along the vertical center axis of the large bevel gear plate 501 and are both meshed with the large bevel gear plate 501. A second synchronizer ring 511 is installed on the side of the first transmission bevel gear 505 close to the generator 7, and a third ratchet pawl 509 is rotatably connected to the side of the second synchronizer ring 511 away from the first transmission bevel gear 505. A torsion spring 513 is clamped at the connection between the third pawl 509 and the second synchronous ring 511 through a clamping groove, a third ratchet 512 meshing with the third pawl 509 is fixed to the outer side of the rotating shaft 502, a first synchronous ring 510 is installed on the side of the second transmission bevel gear 506 away from the first transmission bevel gear 505, a second pawl 507 is connected to the side of the first synchronous ring 510 away from the second transmission bevel gear 506, a torsion spring 513 is also clamped at the connection between the second pawl 507 and the first synchronous ring 510, a second ratchet 508 meshing with the second pawl 507 is fixed on the rotating shaft 502, a first pawl 504 is connected to the top of the U-shaped frame 3, and a first ratchet 503 located on the outer side of the U-shaped frame 3 is fixed on the rotating shaft 502.

[0036] In this embodiment, when the transmission shaft 4 rotates, the first transmission bevel gear 505 and the second transmission bevel gear 506 are driven to rotate in opposite directions through the large bevel gear plate 501. When the transmission shaft 4 drives the large bevel gear plate 501 to rotate clockwise, the large bevel gear plate 501 drives the third ratchet 512 to rotate through the first transmission bevel gear 505, the second synchronous ring 511, and the third pawl 509. At this time, the second transmission bevel gear 506 drives the second pawl 507 to rotate. At this time, the second pawl 507 cannot limit the second ratchet 508, so the second pawl 507 rotates with the second transmission bevel gear 506. Under the action of the torsion spring 513, the rotating coupling 502 swings back and forth, so that the rotating coupling 502 can rotate counterclockwise with the third ratchet 512. When the transmission shaft 4 drives the large bevel gear plate 501 to rotate counterclockwise, the second transmission bevel gear 506 will drive the rotating coupling 502 to rotate counterclockwise through the first synchronous ring 510, the second pawl 507, and the second ratchet 508. At the same time, the third pawl 509 will swing back and forth along the third ratchet 512. In this way, when the transmission shaft 4 rotates back and forth, the rotating coupling 502 always rotates in the same direction, thereby driving the generator 7 to operate, thereby improving the utilization rate of ocean waves and improving power generation efficiency.

[0037] Please refer to Figure 3 , Figure 5 The connection between the first pawl 504 and the U-shaped frame 3 is also clamped with a torsion spring 513 through a clamping groove.

[0038] In this embodiment, by providing this structure, the first pawl 504 can limit the unidirectional rotation of the first ratchet wheel 503 so that the rotating shaft 502 can only rotate in one direction, thereby further improving the rotation stability of the rotating shaft 502.

[0039] Please refer to Figure 3 , Figure 4 , Figure 5 The ratchet teeth on the first ratchet 503 , the third ratchet 512 , and the second ratchet 508 are oriented in the same direction, and the inner wall diameter of the first synchronizer ring 510 is larger than the diameter of the rotating shaft 502 .

[0040] In this embodiment: this structure is set to prevent the second pawl 507 and the third pawl 509 from limiting 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, so as to realize the unidirectional rotation of the rotating coupling 502, and also prevent the rotating coupling 502 from rubbing against the first synchronous ring 510 when rotating.

[0041] Please refer to Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 The distance increasing and positioning member includes a connection box 601 installed on the top of the mounting seat 1 and located below the transmission shaft 4, a guide tube 612 is connected to one side of the connection box 601, a sleeve 602 connected to the mounting seat 1 is installed at one end of the guide tube 612, a piston rod 611 extending to the top of the sleeve 602 is inserted inside the sleeve 602, a push frame 609 located above the sleeve 602 is installed on the top of the piston rod 611, a positioning rod 603 is installed at one end of the transmission shaft 4 away from the large bevel gear plate 501, guide grooves 607 are opened on both sides of the positioning rod 603, and a push frame 609 connected to the mounting seat 1 is installed on the inner side of the push frame 609. A shift pin 608 is slidably connected to the guide groove 607, and return springs 606 connected to the top of the mounting seat 1 are arranged on both sides of the pushing frame 609. A side connecting frame 605 is installed on the outer side of the U-shaped frame 3, and one end of the side connecting frame 605 is rotatably connected to the transfer disk 604. The extension rod 8 is installed on the outer wall of the transfer disk 604, and a bayonet 614 is installed on the inner side of the transfer disk 604. A straight groove connecting rail 615 is sleeved on the bayonet 614, and an insertion rod 610 extending to the inner side of the connecting box 601 is installed on the outer wall of the straight groove connecting rail 615. The bottom end of the insertion rod 610 is installed with a liquid pressure plug block 613 located on the inner side of the connecting box 601.

[0042] In this embodiment, when the extension rod 8 swings, it drives the indexing plate 604 to rotate. At this time, the indexing plate 604 drives the straight groove connecting rail 615 to move upward or downward through the bayonet 614. When the straight groove connecting rail 615 moves downward relative to the connecting box 601, the pressure plug 613 squeezes the aqueous solution inside the connecting box 601. At this time, the aqueous solution inside the connecting box 601 enters the sleeve 602 through the guide tube 612, so as to make the piston rod 611 rise. When the piston rod 611 rises, it can pass through the push frame 609 and the guide groove 609. 07. The shift pin 608 drives the positioning rod 603 to swing, so that the transmission shaft 4 rotates relative to the U-shaped frame 3. Similarly, when the extension rod 8 is restored, the return spring 606 will drive the piston rod 611 to press the aqueous solution inside the sleeve 602 under the action of the elastic restoring force, so that the aqueous solution inside the sleeve 602 enters the connection box 601. At the same time, since the cross-sectional area of ​​the bottom of the sleeve 602 is small, this will cause the swing amplitude of the positioning rod 603 to increase, which can provide power for the generator 7 and further improve the power generation efficiency.

[0043] Please refer to Figure 8 The center of the circle of the bayonet 614 and the rotation disk 604 are in a misaligned state, and the inner width of the straight groove connecting rail 615 is equal to the diameter of the bayonet 614.

[0044] In this embodiment: by setting this structure, when the indexing disk 604 rotates, the latch 614 drives the straight groove connecting rail 615 to move, so that the liquid pressing plug 613 squeezes the aqueous solution inside the connecting box 601.

[0045] Please refer to Figure 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 .

[0046] In this embodiment: by providing this structure, when the liquid pressure plug 613 moves, the moving distance of the piston rod 611 is greater than the moving distance of the liquid pressure plug 613 , thereby increasing the swing amplitude of the positioning rod 603 .

[0047] Please refer to Figure 6 The diameter of the shift pin 608 is equal to the width of the guide groove 607, and the positioning rod 603 is connected to the transmission shaft 4 in an L-shape.

[0048] In this embodiment: by setting this structure, when the piston rod 611 moves up and down, the push frame 609 drives the swing rod 603 to swing through the shift pin 608 and the guide groove 607, so that the transmission shaft 4 can rotate back and forth. At the same time, because one end of the swing rod 603 is far away from the center of the transmission shaft 4, the swing rod 603 and the transmission shaft 4 form a force-saving lever structure, which can reduce the force required for the rotation of the transmission shaft 4.

[0049] Please refer to Figure 7 The two ends of the flow guide tube 612 extend to the inside of the connection box 601 and the sleeve 602 respectively.

[0050] In the present embodiment: by setting up this structure, the guide tube 612 is always located below the liquid pressure plug 613 when the liquid pressure plug 613 moves. At the same time, the two ends of the guide tube 612 can extend to the parts inside the connecting box 601 and the sleeve 602 to limit the liquid pressure plug 613 and the piston rod 611, preventing the liquid pressure plug 613 and the piston rod 611 from moving to a position flush with the guide tube 612.

[0051] In combination with the above-mentioned wave power generation device, a wave power generation method is provided below, which specifically includes the following steps:

[0052] S1: The mounting base 1 is mounted on the shore so that the spoiler 14 is immersed in the seawater. At this time, the floating block 13 floats on the water surface. When the waves impact the spoiler 14, the side direction of the spoiler 14 is changed by the cooperation between the shaft sleeve 9 and the ball shaft connecting rod 10, so that the side of the spoiler 14 faces the waves.

[0053] S2: The waves impact one side of the spoiler 14, and the floating block 13 moves up and down with the impact of the waves, so that the extension rod 8 swings up and down;

[0054] S3: When the extension rod 8 swings, it drives the indexing plate 604 to rotate. At this time, the indexing plate 604 drives the straight groove connecting rail 615 to move upward or downward through the bayonet 614. When the straight groove connecting rail 615 moves downward relative to the connecting box 601, the pressure plug 613 squeezes the aqueous solution inside the connecting box 601. At this time, the aqueous solution inside the connecting box 601 will enter the sleeve 602 through the guide tube 612, so as to make the piston rod 611 rise. When the piston rod 611 rises, it can pass through the push frame 609. , guide groove 607, and shift pin 608 drive the swing rod 603 to swing, so as to rotate the transmission shaft 4 relative to the U-shaped frame 3. Similarly, when the extension rod 8 is restored, the return spring 606 will drive the piston rod 611 to press the aqueous solution inside the sleeve 602 under the action of the elastic restoring force, so as to make the aqueous solution inside the sleeve 602 enter the connection box 601. At the same time, since the cross-sectional area of ​​the bottom of the sleeve 602 is small, this will cause the swing amplitude of the swing rod 603 to increase, thereby causing the transmission shaft 4 to rotate significantly.

[0055] S4: When the transmission shaft 4 rotates, the first transmission bevel gear 505 and the second transmission bevel gear 506 will be driven to rotate in opposite directions through the large bevel gear plate 501. When the transmission shaft 4 drives the large bevel gear plate 501 to rotate clockwise, the large bevel gear plate 501 will drive the third ratchet 512 to rotate through the first transmission bevel gear 505, the second synchronous ring 511 and the third pawl 509. At this time, the second transmission bevel gear 506 will drive the second pawl 507 to rotate. At this time, the second pawl 507 cannot limit the second ratchet 508. At this time, the second pawl 507 will rotate with the rotation of the second transmission bevel gear 506. The torsion spring 513 swings back and forth, so that the rotating coupling 502 rotates counterclockwise with the third ratchet 512. When the transmission shaft 4 drives the large bevel gear plate 501 to rotate counterclockwise, the second transmission bevel gear 506 drives the rotating coupling 502 to rotate counterclockwise through the first synchronous ring 510, the second pawl 507, and the second ratchet 508. At the same time, the third pawl 509 swings back and forth along the third ratchet 512. In this way, when the transmission shaft 4 rotates back and forth, the rotating coupling 502 always rotates in the same direction, thereby driving the generator 7 to operate, thereby improving the utilization rate of waves and improving power generation efficiency.

[0056] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
