Description

Inertial wave power generation device

This invention relates to a wave power generation device, and more particularly to an inertial wave power generation device.

Taiwan's energy policy aims for a "nuclear-free homeland," and it has been phasing out nuclear power generation, relying primarily on thermal power generation for its energy supply. However, thermal power generation is highly dependent on imported fuels, which may lead to price fluctuations and supply risks. Furthermore, thermal power generation emits large amounts of carbon dioxide and air pollution, impacting the environment and health. Therefore, the government is actively promoting the development of renewable energy to ensure a stable power supply while balancing environmental and economic development. As an island surrounded by the sea, Taiwan is also focusing on increasing the proportion of renewable energy by utilizing marine resources, which is currently a major policy and research project.

Wave power generation generally utilizes the potential energy difference, impact force, or buoyancy of wave motion to generate electricity. Traditional wave power generation uses floating bodies on the water surface and mechanical devices that extract displacement to convert energy into mechanical rotation or axial motion, which is then converted into electrical energy by generator sets.

Please refer to Figure 1, which is a three-dimensional schematic diagram of patent TW 1764819 B, illustrating a wave power generation device 11, which includes a base 111, a central fixed pulley assembly 112, a rear fixed pulley assembly 113, a pivot assembly 114, a front floating assembly 115, a rear counterweight assembly 116, and a power generation device 117.

The base 111 is fixed to the shore, and the central fixed pulley assembly 112 and the rear fixed pulley assembly 113 are supported on the shore to provide that the rear counterweight assembly 116 can be guided and hung on the central fixed pulley assembly 112 and the rear fixed pulley assembly 113. The pivot assembly 114 extends to the upper part of the water surface to place the front floating assembly 115 in the sea. The front floating assembly 115 floats on the water surface and has a rope connected to the pivot assembly 114 to transmit the vertical kinetic energy generated during floating to the power generation device 117 through the pivot assembly 114.

Although prior art has revealed an incandescent power generation device, it still has the following drawbacks in practical use:

1. Inability to limit the swing direction of the floating body: The front floating component 115 used in the conventional method is suspended from the pivot component 114 by a rope. However, the connected rope hangs down naturally and cannot fix the front floating component 115. In addition, the waves on the sea surface come from all directions, causing the front floating component 115 to drift freely with the waves.

2. Difficulty in returning to position: The front floating component 115 floats on the water surface to utilize the energy of continuous waves of varying heights. However, in some areas, due to the influence of terrain and wind direction, waves move one after another towards the embankment. The front floating component 115 does not have any structure for returning to position. If the front floating component 115 does not return to position, it will be difficult to receive the energy of the next wave.

3. Difficulty in producing a blocking effect: In the conventional method, the front floating component 115 floats randomly on the water surface. When the wave force pushes the front floating component 115 out, it is not blocked by other mechanisms and can easily move a long distance on the water surface. The unblocked front floating component 115 is easily pushed by waves from other directions and changes direction, making it difficult for the power generation device 117 to obtain complete kinetic energy, thereby affecting the power generation efficiency.

Therefore, how to construct a wave power generation device that can fix the swing direction of the floating body, block the swing stroke so that the power generation module can obtain maximum kinetic energy and achieve the best power generation efficiency, and also has a robust structure, is a goal that relevant technical personnel urgently need to strive for.

In view of this, the purpose of the present invention is to provide an inertial wave power generation device, which includes a floating unit, a limiting unit, and a power generation unit.

The floating unit includes a floating body, a locking structure connected to the floating body, and a floating connection structure disposed on the locking structure.

The limiting unit includes a fixed body disposed underwater and not floating on the water surface, at least one inner baffle wall disposed on the fixed body, and a fixed connection structure disposed between the inner baffle walls. The surfaces of the inner baffle walls face inward. The locking structure is movably disposed between the inner baffle walls. The floating connection structure and the fixed connection structure are interlocked to allow the floating body to swing between a first swing position and a second swing position with the floating connection structure or the fixed connection structure as the center, and to prevent the locking structure from separating from the fixed body. The inner baffle wall is used to limit the swing direction of the floating body.

The power generation unit includes a power generation module disposed on the floating body and a solid body movably disposed on the floating body. The solid body moves within the floating body under inertial force when the floating body swings, and the power generation module receives the kinetic energy of the solid body to generate electricity.

In one embodiment, the floating unit further includes a water-blocking structure disposed at one end of the floating body. The water-blocking structure has two baffles connected to each other and two control components connected to the two baffles. The control components control the connection angle of the two baffles to control the water-blocking area of the water-blocking structure.

In one embodiment, the inertial wave power generation device further includes a reset unit, which includes a reset body connected to the floating unit. The reset body is used to reset the floating body to the first swing position. The floating unit further includes at least one side baffle wall disposed in the locking structure. The surfaces of the side baffle wall face outwards. The inner baffle wall interferes with the side baffle wall to limit the swing direction of the floating body.

In one embodiment, the floating connection structure has a through hole penetrating the two side baffles, and the fixed connection structure has a limiting post connected to the inner baffle wall. The limiting post is inserted into the through hole, and the opening area of the through hole is larger than the cross-sectional area of the limiting post, so that the locking structure can move relative to the fixed body.

In one embodiment, the card holder structure has two spaced-apart horizontal blocks and two spaced-apart vertical blocks that are connected to the two horizontal blocks. The two horizontal blocks and the two vertical blocks cooperate to define the through hole. The distance between the two horizontal blocks and the distance between the two vertical blocks are adjustable.

In one embodiment, the floating connection structure has two side protrusions disposed on the two side baffles, and the fixed connection structure has two fixed upper baffles disposed on the inner baffle, and a plurality of fixed side baffles disposed on the inner baffle and connected to the two fixed upper baffles. The plurality of fixed side baffles are respectively connected to both sides of the two fixed upper baffles and extend downward. The two side protrusions are respectively disposed between the two fixed upper baffles and the plurality of fixed side baffles, and the two side protrusions are movably fixed to the two side baffles.

In one embodiment, the floating unit further includes a monorail structure disposed on the floating body, the solid being a magnet and movably disposed in the monorail structure, and the power generation module having at least one coil assembly wound around the monorail structure.

In one embodiment, the floating unit further includes a monorail structure disposed on the floating body, the solid being movably disposed in the monorail structure, and the power generation module having at least one piezoelectric component disposed on the monorail structure.

In one embodiment, the floating unit further includes a single track structure disposed on the floating body, the solid being movably disposed in the single track structure, the power generation module having a turntable disposed on the floating body, a cross track disposed on the turntable, two sliding members movably disposed on the cross track, and a connector connecting the two sliding members to the solid, the connector having a vertical L-shaped structure.

In one embodiment, the floating unit further includes an elliptical track structure disposed in the floating body, the solid being movably disposed in the elliptical track structure, and the power generation module having at least one elastic baffle disposed in the elliptical track structure.

Based on common knowledge in the art, the above-mentioned preferred conditions can be combined in any way to obtain various embodiments of the present invention. Specifically, the features of the scope of the present invention can be combined with each other in any manner.

The beneficial effects of this invention are that the floating connection structure and the fixed connection structure interfere with each other, so that the floating body can float in a fixed position and avoid drifting outward. The inner baffle wall restricts the two side baffle walls to fix the swing direction of the floating body. The reset body has weight so that the floating body is in the first swing position when the water surface is still. When waves are generated on the water surface, the floating body will be pushed by the waves and move from the first swing position to the second swing position. The solid in the floating body will move due to inertial force. The power generation module obtains the force of the solid movement to generate electricity.

The relevant patent features and technical contents of this invention will be clearly presented in the detailed description of the nine embodiments with reference to the following drawings. Before proceeding with the detailed description, it should be noted that similar elements are represented by the same designation.

Please refer to Figures 2, 3, and 4, which illustrate a first embodiment of an inertial wave power generation device according to the present invention. The inertial wave power generation device includes a floating unit 3, a limiting unit 4, a power generation unit 5, and a reset unit 6. This inertial wave power generation device is installed in water near a coastal area. In actual implementation, the device is not limited to coastal areas and can also be installed in lakeside areas; it should not be limited to these locations.

The floating unit 3 includes a floating body 31, a locking structure 32 connected to the floating body 31, two side walls 33 disposed on the locking structure 32, a floating connection structure 34 disposed on the locking structure 32, and a monorail structure 35 disposed on the floating body 31. The limiting unit 4 includes a fixing body 41, two inner walls 42 disposed on the fixing body 41, and a fixing connection structure 43 disposed between the two inner walls 42. The power generation unit 5 includes a power generation module 51 disposed on the floating body 31 and a solid 52 movably disposed on the floating body 31. The reset unit 6 includes a reset body 61 connected to the floating unit 3.

The floating body 31 has a horizontal cylindrical structure and can float on the water surface 21. The locking structure 32 is a plate fixed to the bottom of the floating body 31. The fixing body 41 is placed underwater and does not float on the water surface. In this first embodiment, the fixing body 41 is two weights placed or fixed to the bottom of the water with a gap between them. The floating connection structure 34 and the fixing connection structure 43 are locked together so that the floating body 31 floats above the fixing body 41. In actual implementation, the floating body 31 can also use other shapes and structures, and the fixing body 41 can also be a weight with a groove shape. It should not be limited to these.

The two side baffles 33 are the left and right surfaces of the locking structure 32, respectively. The two side baffles 33 are parallel to each other and their surfaces face outwards. The two inner baffles 42 are the inner surfaces of the grooves or gaps in the fixing body 41. The two inner baffles 42 are parallel to each other and their surfaces face inwards. The two inner baffles 42 are arranged opposite each other to form a gap. The locking structure 32 is movably disposed between the two inner baffles 42. The two side baffles 33 are adjacent to each other. The two inner baffles 42 have a lateral blocking effect that interferes with the two side baffles 33, thereby limiting the swing direction of the floating body 31 relative to the fixed body 41. In actual implementation, the floating unit 3 can also use other structures to interfere with the two inner baffles 42, and the number of the side baffles 33 and the inner baffles 42 can be one, limiting the swing direction of the floating body 31 by interfering with a single surface on a single surface. This should not be the limitation.

The floating connection structure 34 and the fixed connection structure 43 are interlocked to allow the floating body 31 to swing on the water surface 21. The floating connection structure 34 has a through hole 341 that passes through the two side baffles 33. The fixed connection structure 43 has a limiting post 431 that connects to the two inner baffles 42. The limiting post 431 is inserted into the through hole 341. The floating body 31 swings around the limiting post 431 as the center and can prevent the locking structure 32 from separating from the fixed body 41. The opening area of the through hole 341 is larger than the cross-sectional area of the limiting post 431 so that the locking structure 32 can move relative to the fixed body 41.

Please refer to Figures 3, 5, and 6. The opening structure of the perforation 341 is a longitudinally elongated strip. The limiting post 431 is movably inserted into the perforation 341. The float 31 swings between a first swing position and a second swing position with the floating connection structure 34 or the fixed connection structure 43 as the center. Figure 5 illustrates the state of the float 31 in the first swing position, and Figure 6 illustrates the state of the float 31 in the second swing position.

The repositioning body 61 is used to reposition the float 31 back to the first oscillating position. In this first embodiment, the repositioning body 61 is a weight located on the right side of the float 31. In practice, the repositioning body 61 can also be located on the side of the locking structure 32, and should not be limited thereto. When the water surface 21 is calm, the weight of the repositioning body 61 forces the float 31 to tilt to the right and stabilize in the first oscillating position. When waves are generated on the water surface 21 from right to left, the wave force will push the float 31 from the first oscillating position to the second oscillating position. When the wave force disappears, the weight of the repositioning body 61 will cause the float 31 to move from the second oscillating position back to the first oscillating position. In practice, the repositioning body 61 may use other repositioning structures, and should not be limited to this.

When the floating body 31 oscillates, the solid 52 will bear the thrust of the floating body 31, and when the floating body 31 is stationary, it will generate inertial force and move within the floating body 31, generating kinetic energy. The power generation module 51 receives the kinetic energy of the solid 52 to generate electricity. In the first embodiment, the floating body 31 is provided with a monorail structure 35. The orbital direction of the monorail structure 35 is matched with the oscillation direction of the floating body 31 so that the solid 52 in the monorail structure 35 can receive the optimal wave thrust.

The power generation module 51 has at least one coil assembly 511 wound around the monorail structure 35. The solid 52 is a magnet movably disposed in the monorail structure 35. When the solid 52 passes through the middle of the coil assembly 511, it will cause the coil assembly 511 to generate current. In the first embodiment, there are two sets of coil assemblies 511, which are disposed on the left and right sides inside the float 31 to provide weight to the left and right sides of the float 31, so that the float can be more easily stabilized at the first swing position and more easily reach the second swing position. In practice, the coil assembly 511 can also be disposed in the middle of the float 31 or other positions, and should not be limited thereto.

When the floating body 31 is stable at the first oscillation position, the solid body 52 is located on the right side of the monorail structure 35. When the waves on the water surface 21 push the floating body 31 from the first oscillation position to the second oscillation position, the solid body 52 moves synchronously with the floating body 31, and the solid body 52 still remains on the right side of the monorail structure 35. When the floating body 31 stops oscillating when it is pulled by the limiting post 431, the solid body 52 moves from the right side to the left side of the monorail structure 35 due to inertial force, and passes through the middle of the coil assembly 511. The coil assembly 511 senses the magnetic force of the solid body 52 and generates electricity. When the waves on the water surface 21 disappear, the reset body 61 forces the floating body 31 to move from the second swing position to the first swing position. Under the influence of gravity, the solid 52 moves from the left side to the right side of the monorail structure 35. The coil assembly 511 senses the magnetic force of the solid 52's movement again and generates electricity.

The power generation module 51 is connected to the coil assembly 511 to receive the power generated by the coil assembly 511. In some embodiments, the power generation module 51 may be equipped with a battery to store the power generated by the coil assembly 511. In some embodiments, the power generation module 51 may be equipped with a light-emitting element to receive the power from the coil assembly 511 and emit light. In some embodiments, the power generation module 51 may be a transformer circuit to generate power and connect in parallel to the mains power.

Referring back to Figure 4, the mounting structure 32 has two horizontally spaced blocks 321 and two vertically spaced blocks 322 that are connected to the two horizontally spaced blocks 321. The two horizontally spaced blocks 321 and the two vertically spaced blocks 322 cooperate to define the through hole 341. The spacing between the two horizontally spaced blocks 321 and the spacing between the two vertically spaced blocks 322 can be adjusted.

The float 31 has a track structure at its bottom, and the two longitudinal baffles 322 are movably fixed to the track structure of the float 31, thereby adjusting the width of the perforation 341 to correspond to the outer diameter distance of the limiting post 431. The thicker the outer diameter of the limiting post 431, the farther the distance between the two longitudinal baffles 322; the thinner the outer diameter of the limiting post 431, the closer the distance between the two longitudinal baffles 322.

The two horizontal baffles 321 are movably fixed to the two vertical baffles 322, thereby adjusting the height and position of the perforation 341. Since different water areas have different depths, the height of the different limiting posts 431 will vary when the fixing body 41 is placed on the bottom of different water areas. In order to accommodate the limiting posts 431 of different heights, the position of the two horizontal baffles 321 can be adjusted so that when the floating unit 3 is fixed to the limiting unit 4, the floating body 31 can just float on the water surface 21.

In addition, when waves are generated on the water surface 21, the height of the water surface 21 will change, and with the changes of tides, the water surface 21 will also have different heights at different times. Therefore, the distance between the two horizontal baffles 321 can be adjusted so that the side view structure of the perforation 341 is rectangular. When the water surface 21 is low, the floating body 31 will be at a lower height, and the limiting post 431 will be close to the upper horizontal baffle 321. When the water surface 21 is high, the floating body 31 will be at a higher height, and the limiting post 431 will be close to the lower horizontal baffle 321.

Please refer to Figures 7 and 8, which show a second embodiment of an inertial wave power generation device of the present invention. The second embodiment is substantially the same as the first embodiment, and the similarities will not be described in detail here. The difference is that in the above-mentioned technical solution, the floating connection structure 34 has two side protrusions 342 disposed on the two side baffles 33, the fixed connection structure 43 has two fixed upper baffles 432 disposed on the two inner baffles 42, and a plurality of fixed side baffles 433 disposed on the two inner baffles 42 and connected to the two fixed upper baffles 432.

The plurality of fixed side blocks 433 are respectively connected to the two fixed upper blocks 432 on both sides and extend downward. Each fixed upper block 432 cooperates with the two fixed side blocks 433 to define a fixed groove 434. Each side block wall 33 is provided with a fixed groove 434. The two side protrusions 342 are respectively disposed in the fixed grooves 434 between the two fixed upper blocks 432 and the plurality of fixed side blocks 433. In actual implementation, a fixed lower block can also be provided below each pair of fixed side blocks 433, and this should not be a limitation.

The fixed groove 434 defined by the fixed upper baffle 432 and the two fixed side baffles 433 is rectangular. The width of the fixed groove 434 matches the width of the side protrusion 342. The height of the fixed groove 434 adapts to the change in the height of the water surface 21. When the water surface 21 is higher, the side protrusion 342 is located at the higher position in the fixed groove 434. When the water surface 21 is lower, the side protrusion 342 is located at the lower position in the fixed groove 434.

The two protrusions 342 are movably fixed to the two side blocks 33. In the second embodiment, the locking structure 32 has two first mounting portions 323 disposed on both sides of the side blocks 33, and a second mounting portion 324 disposed on the two first mounting portions 323. The first mounting portions 323 and the second mounting portions 324 are slide rails and internally mounted locks, but are not limited thereto. The two sides of the second mounting part 324 can be locked at any position on the two first mounting parts 323 to adjust the height of the second mounting part 324. The side protrusion 342 can be locked at any position on the second mounting part 324 to adjust the left and right position of the side protrusion 342, thereby providing adjustment of the position of the side protrusion 342 on the side wall 33.

In the second embodiment, the fixed grooves 434 are in the same position and have the same structure. The two fixed grooves 434 are vertical groove structures and are arranged opposite to each other. The two protrusions 342 are respectively accommodated in the two fixed grooves 434. The two protrusions 342, whose positions can be adjusted on the two side baffles 33, can make the float 31 float above the fixed body 41 according to the water level. Not only will the two protrusions 342 not fall out of the two fixed grooves 434, but when waves are generated on the water surface 21, the two fixed grooves 434 will also have an interference braking effect on the two protrusions 342, causing the float 31 to swing.

In this second embodiment, the power generation module 51 does not use magnetic induction power generation. The power generation module 51 has two piezoelectric components 512 disposed on the monorail structure 35. The two piezoelectric components 512 are respectively disposed on the left and right ends of the inner side of the monorail structure 35. In actual implementation, only one piezoelectric component 512 may be disposed, which may be disposed on the left side or the right side, and should not be limited thereto. In some embodiments, the piezoelectric component 512 uses piezoelectric materials (such as PZT lead zirconium titanate, PVDF polyvinylidene fluoride) to generate electricity when subjected to pressure, impact or vibration, but this is not a limitation.

When the floating body 31 is stably positioned at the first oscillation position, it oscillates due to the weight of the repositioning body 61. The solid body 52, under the influence of gravity, is located on the right side of the monorail structure 35. When waves are generated on the water surface 21, propelling the floating body 31 to oscillate from the first oscillation position to the second oscillation position, the solid body 52 remains in its original position. On the right side of the monorail structure 35, when the fixed connection structure 43 interferes with the floating connection structure 34 to force the floating body 31 to stop swaying, the solid 52 moves from the right side to the left side of the monorail structure 35 under the influence of the inertial force. When the solid 52 hits the piezoelectric component 512 on the left side, it generates electricity, and the power generation module 51 outputs the electricity. When the waves on the water surface 21 disappear, the floating body 31 is swayed by the weight of the reset body 61 and moves from the second swaying position to the first swaying position. The solid body 52 moves from the left side to the right side of the monorail structure 35 under the influence of the inertial force. When the solid body 52 hits the piezoelectric component 512 on the right side, it generates electricity, and the power generation module 51 outputs the electricity.

In some embodiments, the reset unit 6 further includes a position control module disposed on the float 31, the position control module being connected to the reset body 61, the position control module being used to flexibly control the left and right position of the reset body 61 on the float 31, thereby controlling the center of gravity of the float 31 so that the float 31 can swing smoothly on the water surface.

It is worth mentioning that when the weight of the reset body 61 is too heavy, the float 31 is not easy to move from the first swing position to the second swing position. However, when the weight of the reset body 61 is too light, the float 31 cannot smoothly return from the second swing position to the first swing position. Therefore, in some embodiments, the weight of the reset body 61 can be flexibly adjusted to match the center of gravity and buoyancy of the float 31 to the most suitable weight so that the float 31 can swing smoothly on the water surface 21.

Please refer to Figure 9, which shows a third embodiment of an inertial wave power generation device according to the present invention. This third embodiment is largely the same as the second embodiment, and the similarities will not be described in detail here. The difference is that in the third embodiment, the two fixing grooves 434 formed between the two fixed upper blocks 432 and the plurality of fixed side blocks 433 are inclined, wherein the low point of the fixing groove 434 faces the direction of the wave source. In actual implementation, the structure of the fixing groove 434 can also be an arc-shaped groove structure, and should not be limited thereto.

When the water surface 21 is calm, the floating body 31 is stabilized in the first oscillating position under the influence of the repositioning body 61. At this time, the side protrusion 342 is located at the lower part of the fixing groove 434. When waves are generated on the water surface 21, the waves not only push the floating body 31 from the first oscillating position to the second oscillating position, but also push the side protrusion 342 from the fixing groove 434. The float 31 moves from the lower position to the higher position and is finally stopped by the fixed upper stop 432. When the waves on the water surface 21 disappear, the reset body 61 forces the float 31 to move from the second swing position to the first swing position. Under the influence of gravity, the side protrusion 342 moves from the higher position to the lower position of the fixed groove 434.

Please refer to Figure 10, which shows a fourth embodiment of an inertial wave power generation device of the present invention. This fourth embodiment is largely the same as the second embodiment, and the similarities will not be described in detail here. The difference is that in the above-mentioned technical solution, the floating unit 3 in the fourth embodiment further includes a water-blocking structure 37 disposed at one end of the floating body 31. The water-blocking structure 37 has two baffles 371 connected to each other, and two control components 372 connected to the two baffles 371. The control components 372 control the connection angle of the two baffles 371 to control the water-blocking area of the water-blocking structure 37.

The second baffle 371 is disposed on the floating body 31 and located at the end facing the wave source. When the second baffle 371 is unfolded, it presents a flat surface to increase the area of the water-blocking structure 37, thereby improving the efficiency of collecting wave power and ensuring power generation efficiency. When waves are generated on the water surface 21, the waves will hit the second baffle 371, and the second baffle 371 will transmit the force to the floating body 31, causing it to oscillate.

When the waves on the water surface 21 are normal or small, the control component 372 controls the second deflector 371 to be in an extended state to increase the area of wave impact, thereby increasing the kinetic energy received from the waves. When the waves on the water surface 21 become larger or even destructive due to weather factors, the control component 372 controls the second deflector 371 to be in a retracted state to reduce the area of wave impact, thereby reducing the kinetic energy received from the waves and preventing damage to the inertial wave power generation device.

In the fourth embodiment, the control component 372 uses wireless transmission technology to control the hinge angle of the second stop 371, allowing the user to control it directly from the shore. In practice, the control component 372 can also use other technologies to control the hinge angle of the second stop 371, and should not be limited to this.

Please refer to Figures 11 and 12, which show a fifth embodiment of an inertial wave power generation device of the present invention. The fifth embodiment is largely the same as the first embodiment, and the similarities will not be described in detail here. The difference is that in the above-mentioned technical solution, the power generation module 51 in the fifth embodiment has a turntable 513 disposed on the floating body 31, a cross track 514 disposed on the turntable 513, two sliding members 515 movably disposed on the cross track 514, and a connecting member 516 connecting the two sliding members 515 to the solid 52. The power generation module 51 is a power generator. The turntable 513 is connected to the rotor of the power generation module 51 so that the power generation module 51 can generate electricity externally. The structure of the connecting member 516 is vertically L-shaped.

The monorail structure 35 is disposed on the outer side of the turntable 513 and extends outward in a straight line corresponding to the axis of the turntable 513. The solid 52 can move between a first moving position 521 and a second moving position 522 in the monorail structure 35. When the floating body 31 is in the first swing position, the solid 52 is in the first moving position 521 in the monorail structure 35 (as shown in Figure 11). When the floating body 31 is in the second swing position, the solid 52 is in the second moving position 522 in the monorail structure 35 (as shown in Figure 12).

The connector 516 has a first connecting rod connected to the solid 52 and a second connecting rod whose two ends are connected to the two sliding members 515. The first connecting rod and the second connecting rod are perpendicular to each other and form an L-shape. The cross track 514 is composed of two straight tracks. The two sliding members 515 are respectively disposed in the two straight tracks. The length of the second connecting rod is less than the radius of the turntable 513, so that when one of the sliding members 515 is located on the outer side of the turntable 513, the other sliding member 515 can pass through the center of the turntable 513.

When the solid 52 moves within the monorail structure 35, the generated kinetic energy first applies force to one of the sliding members 515 through the first connecting rod, and then to the other sliding member 515 through the second connecting rod. Since the second connecting rod is perpendicular to the first connecting rod, different torques are generated on the two sliding members 515, and the kinetic energy is transmitted to the turntable 513 through the cross rail 514, causing it to rotate. When the turntable 513 rotates, the power generation module 51 can generate electricity. In some embodiments, the power generation module 51 can also use a transmission method similar to that of a millstone rotation to convert linear motion into rotational motion.

Please refer to Figure 13, which shows a sixth embodiment of an inertial wave power generation device of the present invention. The sixth embodiment is largely the same as the fifth embodiment, and the similarities will not be described in detail here. The difference is that in the above technical solution, the power generation unit 5 in the sixth embodiment further includes a transmission module 53, which is disposed between the power generation module 51 and the solid 52.

The power generation module 51 is a motor-type generator. The transmission module 53 has a turntable 531 connected to the rotating shaft of the power generation module 51, a lever 532 connected to the turntable 531, a force rod 533 connected to the lever 532 and the solid 52, and a one-way transmission component 534 disposed in the turntable 531. The force rod 533 is suspended by a suspension rope 54. The transmission module 53 is similar to a millstone-driven transmission mechanism, but is not limited thereto.

The solid 52 is disposed in a monorail structure 35. When the floating body 31 floats on the water surface 21 and is impacted by waves, the solid 52 moves within the floating body 31 and pushes or pulls the lever 533. The lever 533 transmits force to the rotary rod 532 and drives the turntable 531 to rotate. The turntable 531 pushes the one-way transmission component 534 to make the power generation module 51 rotate. When the solid 52 stops, the turntable 531 will stop synchronously, but the one-way transmission component 534 will not obstruct the power generation module 51, so the rotating shaft of the power generation module 51 will continue to rotate due to inertial force. The rotating shaft of the power generation module 51 will stop rotating until the energy of rotation is exhausted. In the sixth embodiment, the one-way transmission assembly 534 uses an internal ratchet mechanism, similar to the flywheel structure on a bicycle. In actual implementation, the one-way transmission assembly 534 may also use an external ratchet mechanism or other unidirectional rotating mechanisms, and should not be limited thereto.

Please refer to Figures 14 and 15, which show a seventh embodiment of an inertial wave power generation device of the present invention. This seventh embodiment is largely the same as the sixth embodiment, and the similarities will not be described in detail here. The difference is that in the above technical solution, the solid 52 in the seventh embodiment is an eccentric weight block disposed on a disk 523. In actual implementation, the disk 523 may not be disposed, and the solid 52 may be directly connected to a one-way transmission component 534. This should not be the limitation.

When the floating body 31 oscillates on the water surface 21, it generates kinetic energy in the solid 52 with weight, causing the solid 52 to move inside the floating body 31 and causing the disc 523 to rotate. When the disc 523 rotates, it drives the unidirectional transmission component 534 and the rotating shaft of the power generation module 51 to rotate.

The one-way transmission component 534 is a freewheel structure similar to that on a bicycle, so that when the disc 523 rotates clockwise or counterclockwise, the second shaft 536 will only rotate in one direction. In practice, the one-way transmission component 534 can also directly restrict the disc 523 to rotate in only one direction, and should not be limited to this. The disc 523 has a turntable 531 inside, the outer ring of the one-way transmission component 534 is connected to the turntable 531, and the inner ring of the one-way transmission component 534 is connected to the shaft of the generator module 51. In practice, the one-way transmission component 534 can also be designed with other structures, and should not be limited to this.

The first oscillation position of the floating body 31 is located below in Figures 14 and 15, and the second oscillation position of the floating body 31 is located above in Figures 14 and 15. When the floating body 31 is in the first oscillation position, the solid body 52 is affected by gravity and is located below the disc 523 (as shown in Figure 14). When the waves on the water surface 21 push the floating body 31 from the first oscillation position to the second oscillation position, the solid body 52 will cause the disc 523 to rotate and move above the disc 523 (as shown in Figure 15). When the repositioning body 61 forces the floating body 31 to move from the second oscillation position to the first oscillation position, the solid body 52 will cause the disc 523 to rotate and move below the disc 523 (as shown in Figure 14). When the disc 523 rotates counterclockwise, the kinetic energy is transmitted to the shaft of the power generation module 51 through the one-way transmission component 534, causing it to rotate until the energy is exhausted and then stop. However, when the disc 523 rotates clockwise, the one-way transmission component 534 does not transmit kinetic energy to the power generation module 51, and the shaft of the power generation module 51 does not rotate.

Please refer to Figure 16, which shows an eighth embodiment of an inertial wave power generation device according to the present invention. This eighth embodiment is largely the same as the first embodiment, and the similarities will not be described in detail here. The difference is that in the above-described technical solution, the floating unit 3 further includes an elliptical track structure 36 disposed in the floating body 31. The solid 52 is movably disposed in the elliptical track structure 36, and the power generation module 51 has at least one elastic baffle 517 disposed in the elliptical track structure 36.

In this eighth embodiment, the elliptical track structure 36 is provided with a plurality of elastic baffles 517, each elastic baffle 517 having an angle less than 90 degrees with the side wall of the elliptical track structure 36, and the plurality of elastic baffles 517 being inclined in a clockwise direction in the elliptical track structure 36. In some embodiments, the angle between the elastic baffle 517 and the side wall of the elliptical track structure 36 is 30 degrees to 60 degrees, but is not limited thereto. When the solid 52 moves clockwise within the elliptical track structure 36, the kinetic energy of the solid 52 during its movement can press down the elastic baffle 517, causing the elastic baffle 517 to be pressed into the corresponding dotted line position, and the solid 52 will not sink into the dotted line position, thus affecting its movement. In some embodiments, the rotating shaft of the plurality of elastic baffles 517 can be a transmission mechanical structure (not shown in the figure) connected to a screw gear, driving the rotor of the power generation module 51 to rotate, so that the power generation module 51 generates electricity.

If the solid 52 moves counterclockwise in the elliptical track structure 36, the elastic baffle 517 will instead act as a stop for the solid 52, preventing it from moving counterclockwise in the elliptical track structure 36. Since the elastic baffle 517 can only allow the solid 52 to move clockwise in the elliptical track structure 36, it has a counterclockwise stopping effect.

In addition, an activation position 361 and an end position 362 are defined in the elliptical track structure 36. The activation position 361 is the starting point of the solid 52 when it moves under inertial force, and the end position 362 is the ending point of the solid 52 when it moves under inertial force. The height of the activation position 361 is lower than the height of the end position 362. The activation position 361 is the lowest point of the elliptical track structure 36, and the end position 362 is the highest point of the elliptical track structure 36. In actual implementation, the heights of the activation position 361 and the end position 362 can be adjusted according to the actual situation and should not be limited thereto.

In this eighth embodiment, the activation position 361 is located at the lowest point of the elliptical track structure 36. An elastic baffle 517 can be provided on the side of the activation position 361 to provide kinetic thrust to the solid 52. When the floating body 31 is stable at the first oscillation position, the solid 52 is located at the activation position 361 of the elliptical track structure 36. When waves are generated on the water surface 21, causing the floating body 31 to move from the first oscillation position to the second oscillation position, the elastic baffle 517 provided on the side of the activation position 361 pushes the solid 52, causing the solid 52 to move from the activation position 361 to the termination position. Position 362: During its movement, the solid 52 can exert pressure on the elastic baffle 517 it passes through. Upon reaching the end position 362, the solid 52 will continue to move forward due to inertia. When the waves on the water surface 21 disappear, the floating body 31 moves from the second swing position to the first swing position under the action of the reset body 61. At this time, due to the thrust and gravity, the solid 52 returns to the starting position. In actual implementation, the elliptical track structure 36 can also be provided with multiple start positions 361 and multiple end positions 362, and should not be limited to this.

Please refer to Figure 17, which shows a ninth embodiment of an inertial wave power generation device of the present invention. The ninth embodiment is largely the same as the first embodiment, and the similarities will not be described in detail here. The difference is that in the above-mentioned technical solution, the monorail structure 35 in the ninth embodiment includes two gears 351 spaced apart on the floating body 31, a timing belt 352 disposed on the two gears 351, two side baffles 353 spaced apart inside the floating body 31, and two buffers 354 respectively disposed on the two side baffles 353.

The solid 52 is fixed to the timing belt 352 and is movably disposed between the two side stops 353. One of the gears 351 is provided with a one-way transmission component 534 for connecting to the rotating shaft of the motor-type generator module 51.

In this ninth embodiment, the first oscillation position of the floating body 31 is located on the right side, and the second oscillation position of the floating body 31 is located on the left side. When the floating body 31 is in the first oscillation position, the right side of the monorail structure 35 is lower, so the solid 52 is affected by gravity and contacts the right side buffer 354. When the waves on the water surface 21 move from right to left, the floating body 31 swings from the first swing position to the second swing position. At this time, the right buffer 354 pushes the solid 52 to generate inertial force and move it to the left buffer 354. When the solid 52 moves, it will drive the timing belt 352 and rotate the two-gear 351. The one-way transmission component 534 rotates the shaft of the power generation module 51 to generate electricity. When the waves on the water surface 21 disappear, the reset body 61 swings the floating body 31 from the second swing position to the first swing position. The solid body 52 moves to the right and contacts the right buffer 354. At this time, although the solid body 52 drives the timing belt 352 and rotates the two-gear 351, the one-way transmission component 534 will not rotate the shaft of the power generation module 51. Therefore, the shaft of the power generation module 51 will only rotate in one direction.

The two buffers 354 use a hydraulic spring buffer, but this is not a limitation. The buffers 354 on both sides can buffer the impact force of the solid 52 to prevent the side block 353 from being damaged by the impact. In actual implementation, the buffers 354 may not be provided on the side block 353, and this should not be a limitation.

The range of movement of the solid 52 is between the two gears 351, which can prevent the solid 52 from colliding with the two gears 351 and can also prevent damage to the timing belt 352 when it rotates. In the ninth embodiment, the range of movement of the solid 52 is limited by the two side stops 353 or the two buffers 354. In actual implementation, the solid 52 can also use other methods to limit the range of movement, and should not be limited to this.

As can be seen from the above description, the inertial wave power generation device of this invention does indeed have the following effects:

1. Effectively harnessing wave power: The distance between the two side baffles 33 and the distance between the two inner baffles 42 are coordinated to allow the fixed body 41 to resist the side of the locking structure 32 and limit the swing direction of the floating body 31. This allows the swing direction of the floating body 31 to be aligned with the movement direction of the waves on the water surface 21, enabling the power generation module 51 installed in the floating body 31 to effectively harness wave power for power generation.

2. Automatic return to position: The waves on the water surface 21 will generate waves in a fixed direction and one after another depending on factors such as terrain and wind direction. After the waves move the floating body 31 from the first swing position to the second swing position, the reset body 61 can forcibly return the floating body 31 to the first swing position so as to receive the force of the waves in the same direction again. Therefore, the reset body 61 can provide the floating body 31 with the function of automatic return to position.

Third, it can be installed at different water depths: Since different waters have different depths, when the fixed body 41 is installed at the bottom of the water, the structure or position of the floating connection structure 34 on the locking structure 32 can be adjusted to adapt to waters of various depths. In addition, the floating connection structure 34 installed on the locking structure 32 has longitudinal perforations 341, which can adapt to the changes in tides so that the floating body 31 can swing on the water surface 21.

In summary, the width of the locking structure 32 corresponds to the distance between the two inner baffle walls 42 in the fixed body 41, so that the two inner baffle walls 42 can provide a lateral baffle effect on the two side baffle walls 33, thereby fixing the swing direction of the float 31 and enabling the power generation module 51 to effectively receive the force of the waves. The floating connection structure 34 has a perforation 341 that can adjust its height and width, and also has a side protrusion 342 that can adjust its position to connect fixed connection structures 43 at different heights, so that the fixed body 41 can be placed in waters of various depths, and the float 31 can swing relative to the fixed body 41. The fixed body 41 stabilizes the fixed connection structure 43 on the bottom of the water. When the floating body 31 swings on the water surface 21, the fixed connection structure 43 can provide a braking effect when the floating body 31 swings, so that the solid body 52 can move in the floating body 31 due to inertial force. This allows the power generation module 51 to receive the kinetic energy of the solid body 52 and generate electricity externally, thus achieving the purpose of this invention.

However, the above are merely nine embodiments of this invention and should not be used to limit the scope of the invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the description of the invention shall still fall within the scope of the patent application of this invention.
