[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the basis of the Chinese patent application filed with the State Intellectual Property Office of China on February 8, 2024, with application number: 202410778945, and the name of the invention: "A wave power generation system", and claims partial priority thereof. The content of the Chinese patent application is hereby introduced into the text of this application. Technical Field

[0003] The invention relates to a method and device for generating power or obtaining energy from waves on a non-shore surface. Background Art

[0004] Developing green energy and reducing greenhouse gas emissions are important paths to sustainable development. Ocean tides and waves hold enormous potential, but the drop of a single wave is not very large, resulting in low energy conversion efficiency. This means it is not possible to increase the drop by building a dam on a river. Currently, there are two methods for generating power using wave power: one is shore-based, with a buoyancy device absorbing energy as the waves rise and fall, but coastline resources are limited; the other is surface-based, with the generator installed in the ocean and anchored to a platform to secure it to the surface. However, both methods have the following drawbacks:

[0005] 1. Failure to consider installing an automatic angle adjustment device parallel to the wave crest or trough to automatically adjust the angle between the length direction of the floating platform's rocker arm and the direction of the wave's incoming wave to a perpendicular 90-degree angle. Under the same conditions, when the angle is 90 degrees, the rocker arm swings to the maximum, and when the angle is 180 degrees (i.e., the length direction of the platform's rocker arm is parallel to the direction of the wave's incoming wave), the rocker arm will not swing;

[0006] 2. Failure to consider installing a device on the floating platform to balance the platform with the water surface, so as to automatically adjust the balance between the floating platform and the water surface and maximize the swing of the rocker arm under the same conditions. If the floating platform tilts with the rise and fall of waves, the swing angle of the rocker arm will be greatly reduced.

[0007] 3. It was not considered to set up a rocker arm float moving component at the end of the rocker arm extending outside the platform. When the wave size changes, that is, when the waves are large: the walking component on the rocker arm that is propelled towards the waves has a large water draft, pulling the float to move automatically outward; when the waves are small: the walking component on the rocker arm that is not propelled towards the waves has a large water draft, pulling the float to move automatically inward; making the rocker arm swing towards the wave crest and trough to obtain the maximum swing amplitude.

[0008] Due to the above defects of the existing wave power generation device, the swing arc of the rocker arm on the wave power generation device is small, and the maximum contrast between the crest and the trough cannot be effectively achieved. The height difference is low, so the energy extraction efficiency is low.

[0009] 4. Existing water wave power generation devices cannot withstand typhoons and are easily damaged, unless a super-large floating platform is used to resist typhoons. However, the investment cost is too high and it does not have investment value. Summary of the Invention

[0010] The purpose of the present invention is to design a floating platform on the sea surface, which absorbs the huge energy hidden in the ups and downs of the waves for power generation, and is provided with an automatic adjustment device for the angle of the parallel line of the wave crest or the trough, to automatically adjust the floating platform to be roughly perpendicular to the parallel line of the wave crest or the trough; a device for balancing the floating platform on the water and the water surface is also provided, to automatically adjust the balance of the floating platform on the water and the water surface; a rocker arm float moving component is also provided. When the size of the waves changes, that is, when the waves are large: the walking component on the rocker arm that is propelled towards the waves has a large draft, and the float is pulled to move outward automatically. When the waves are small: the walking component on the rocker arm that is not propelled towards the waves has a large draft, and the float is pulled to move inward automatically, so that the rocker arm swings toward the wave crest and trough, obtaining the maximum swing amplitude, thereby maximizing the absorption of the up and down difference of the waves for power generation.

[0011] The wave power generation system of the present invention comprises: an above-water floating platform, at least one rocker arm device, at least one main shaft transmission assembly, and at least one power generation assembly;

[0012] The floating platform on the water includes: an automatic adjustment device for the angle of the parallel line of the wave crest or trough, which automatically adjusts the floating platform to be approximately perpendicular to the parallel line of the wave crest or trough;

[0013] The device for automatically adjusting the angle of parallel lines of wave crests or troughs comprises: a first wave-facing surface and a second wave-facing surface that are substantially symmetrical;

[0014] The rocker arm device includes: a rocker arm and a rocker arm power transmission component;

[0015] The rocker arm device is installed on a floating platform on the water.

[0019] The device for automatically adjusting the angle of the parallel line of the wave crest or trough is installed on a floating platform on the water, and the small flared opening of the inner eight shape and the small end of the large and small head shape are directed toward the parallel line of the wave crest or trough, and the large flared opening of the outer eight shape is directed toward the parallel line of the wave crest or trough, and the floating platform on the water is anchored and fixed on the water surface of a region. When the angle between the floating platform on the water and the parallel line of the wave crest or trough is not perpendicular to 90 degrees, the first wave-facing surface and the second wave-facing surface are subjected to two unequal thrusts from the direction of the parallel line of the wave crest or trough, and the one subjected to greater force is adjusted in the direction of less force. After multiple thrust adjustments, the two thrusts from the direction of the wave line on the first wave-facing surface and the second wave-facing surface are basically equal, and finally the angle between the floating platform on the water and the parallel line of the wave crest or trough is automatically adjusted to tend toward 90 degrees perpendicular. Specifically, the small flared opening of the inner eight shape and the small end of the large and small head shape are directed toward the parallel line of the wave crest or trough, and the large flared opening of the outer eight shape is directed toward the parallel line of the wave crest or trough.

[0020] The traction anchor pulls the floating platform on the water so that the floating platform on the water is fixed on the water surface in a certain area;

[0021] The platform float has a cavity, an inlet and an outlet; the floating platform can be controlled to float up or down and rise and fall by controlling the water and / or gas volume in and out of the inlet and outlet of the platform float.

[0022] The floating platform further comprises one or more balancing poles arranged below the platform and inserted into the water;

[0023] The balance bar is provided with a counterweight; the tail end of the balance bar is connected to the counterweight, the balance bar is fixedly and / or movably connected under the platform, and the horizontal balance automatic adjustment mechanism automatically adjusts the balance between the water platform and the water surface;

[0024] There are two or more balancing rods, each of which is connected to a counterweight at its tail end; or

[0025] Some or all of the balancing poles are connected, and the lower ends of the balancing poles are each connected to a counterweight, or some of the connected balancing poles are equipped with a counterweight, or some are not connected to a counterweight (no counterweight).

[0026] The lower end of the balance bar also includes: a water-blocking panel, which is fixedly mounted on the balance bar and has a shape of an arc, a circle, an ellipse or other water-blocking shape;

[0027] The main shaft transmission assembly includes: a main shaft, at least one or more motor transmission mechanisms, and at least one or more rocker arm transmission mechanisms; the motor transmission mechanism and the rocker arm transmission mechanism are installed and fixed on the main shaft, and the main shaft is installed on the platform.

[0028] The motor transmission mechanism and the rocker arm transmission mechanism are gear transmission mechanism, rope transmission mechanism, chain structure, belt transmission mechanism (including synchronous belt), etc.

[0029] The rocker device also includes: a rocker rod, a main shaft transmission mechanism, a float, and a fulcrum. The rocker transmission mechanism is connected to the mechanism of the main shaft transmission to drive the main shaft to rotate; the float is installed at the tail end of the rocker rod; one end of the fulcrum is fixedly installed on the platform, and the other end is movably connected to the rocker rod.

[0030] When multiple rocker arm devices are installed, the length of the rocker arm rods can be set according to needs, and the rocker arm rods can be staggered and installed on the floating platform device.

[0031] The present invention also provides a method for obtaining wave energy, comprising: a floating platform on water, at least one set of rocker devices, and at least one set of main shaft transmission components; the rocker device comprises a rocker extending toward the sea surface and a rocker float on the rocker, the floating platform on water balances and accepts the thrust of the waves, keeping the floating platform on water roughly parallel to the wave line, and the rocker float moves on the rocker as the wave crest changes.

[0032] The reason is that when the waves are large, the distance between waves is wide, and the rocker arm float moves outwards from the rocking wall; when the waves are small, the distance between waves is narrow, and the rocker arm float moves inwards.

[0033] A main shaft transmission device is provided on the floating platform. The main shaft transmission assembly converts the swinging kinetic energy of the rocker arm into the rotational kinetic energy of the main shaft transmission assembly. The main shaft transmission assembly rotates to drive the generator assembly to generate electricity, or the main shaft transmission assembly rotates to lift the water to a high level, or compresses the air, and converts it into potential energy or other energy.

[0034] The floating platform provided by the present invention roughly rises and falls with the changes in the waves, with a small swing amplitude. The designed rocker arm extends from the platform into the sea surface, floats with the swing of the waves, with a large swing amplitude, and drives the main shaft gear to rotate through the rack on the rocker arm, which transmits the power to the generator rotor to rotate and generate electricity.

[0085] Definition: Crest or trough parallel line: In the direction of the wave's forward movement, the line parallel to the crest and trough is called the crest or trough parallel line.

[0086] Example 1:

[0087] As shown in FIG1 , a wave power generation system comprises: a floating platform (1), eight rocker devices (2) arranged on two sides of the platform, a set of main shaft transmission components (3), and a set of power generation components (4);

[0088] The floating platform on water comprises: an automatic adjustment device (5) for adjusting the angle of a wave crest or wave trough parallel line, which automatically adjusts the platform to be perpendicular to the wave crest or wave trough parallel line;

[0089] The device for automatically adjusting the angle of parallel lines of wave crests or troughs comprises: a first wave-facing surface (12) and a second wave-facing surface (13) that are substantially symmetrical;

[0090] The rocker arm device (2) comprises: a rocker arm (21) and a rocker arm power transmission member (22);

[0091] The rocker arm device (2) is pivotally connected to the support (14) of the floating platform on the water. One end of the rocker arm (21) is connected to the main shaft assembly (3) in a transmission manner, and the other end extends outside the platform to rise and fall with the waves. A water wheel (5) can be optionally mounted on the main shaft of the platform. The water wheel has blades (51) and a water tank (52). The blades are driven by the waves to rotate, and the central axis hole is mounted on the main shaft.

[0092] The main shaft transmission assembly converts the swinging kinetic energy of the rocker arm into the rotational kinetic energy of the main shaft transmission assembly, and the main shaft transmission assembly 3 rotates to drive the generator assembly 4 to operate and generate electricity; as shown in Figure 1, eight rocker arms (21) are arranged in two groups of staggered lengths in both directions, which can provide a continuous source of power for the generator.

[0093] Figure 3 shows an integrated floating platform. It includes two symmetrically arranged buoyant bodies 11. Floating bodies 11 are hollow structures with inlets 11.1 and 11.2. The inlets allow air to enter during buoyancy and water to enter during descent, while the outlets allow air to escape during descent and water to escape during buoyancy. The platform's underside has a trumpet-like longitudinal cross-section, forming an arc centered on the platform's centerline. A support 14 is provided on the upper surface of the platform for mounting a rocker mechanism.

[0094] The device for automatically adjusting the angle of the parallel line of the wave crest or trough can be the shape of a floating platform on the water or its components, or an independent component installed on the floating platform on the water. When the angle between the floating platform on the water and the "parallel line of the wave crest or trough" is not perpendicular, the first wave-facing surface (12) and the second wave-facing surface (13) are subjected to two unequal thrusts from the direction of the waves, and the side subjected to greater force swings in the direction of less force. After multiple thrust adjustments, the first wave-facing surface (12) and the second wave-facing surface (13) are subjected to two thrusts from the direction of the wave line that are substantially equal, and finally the angle between the floating platform on the water and the parallel line of the wave crest or trough is automatically adjusted to 90°, which is perpendicular to the vertical. Specifically. In this embodiment, the device for automatically adjusting the angle of the parallel line of the wave crest or trough is shown in FIG3 , which is a cone-shaped platform float, and the first wave-facing surface (12) and the second wave-facing surface (13) are provided on the side facing the wave crest, and the two are symmetrically arranged.

[0095] FIG4 is a split-type floating platform on water, comprising four floats (11) and a frame (13). The floats (11) are fixedly mounted on the frame (13). The floats (11) are hollow bodies, provided with an inlet (11.1) and an outlet (11.2). The inlet is for air intake when floating up and water intake when diving, and the outlet is for exhaust when the platform dives and water discharge when floating up. The bottom surface of the platform is in the shape of a trumpet longitudinal section, presenting an arc with the platform centerline as the top. The upper end surface of the platform is provided with a support (14) for mounting a rocker device.

[0096] In this embodiment of the platform, the two middle floats are cylindrical with tapered ends, as shown in FIG5 ; the two end floats are of the same shape, as shown in FIG6 , which are box-shaped cavities, with the floating surface being an arc surface, the side and bottom surfaces being rectangular, and the water-facing surface being tapered. Fine-tuning bolts (11.4) are provided on the assembly of the float and the frame (13), and fine-tuning nuts (11.5) are provided on the frame. By adjusting the fine-tuning bolts (11.4) and nuts (11.5), the angle between the float and the frame can be adjusted so that the side of the float is perpendicular to the wave crest line, or there is some deviation. In some sea areas, there are undercurrents, and the direction of the water flow deviates from the direction of the waves. This design can correct such deviations, so that the floating platform on the water can be roughly perpendicular to the direction of the water flow. FIG7 shows the positional relationship between the floating platform on the water and the wave crest and trough.

[0097] Figures 8 and 9 show the structure of the first wave-facing surface 12 and the second wave-facing surface 13 as separate devices. Figure 9 is a structural diagram of a balancing wave-facing component, which has symmetrical wave-facing surfaces and is connected by a connecting rod. The floating platform on the water has a symmetrical first wave-facing surface (12) and a second wave-facing surface (13) facing the direction of wave propulsion, and also has a first wave-facing surface (12) and a second wave-facing surface (13) facing away from the direction of wave propulsion, which has a better angle adjustment function, and the symmetrical arrangement makes the floating platform 1 on the water more stable.

[0098] As shown in Figures 10 and 11, the bottom surface of the floating platform is equipped with one or more balancing poles (6) arranged below the platform and inserted into the water, and a counterweight (62) is provided at the end of the balancing pole; the balancing pole can be a single one, or multiple balancing poles, as shown in Figure 12, multiple balancing poles are connected, which has better strength and can be connected to be longer; Figure 13 shows a telescopic balancing pole (6), which includes an upper telescopic tube (6.1), a middle telescopic tube (6.2), a lower telescopic tube (6.3), and a counterweight (62) at the end. Connect a counterweight (62); Figure 14 shows another balance bar, which is bendable. Its working state is straight, or multiple symmetrical, and can also be transformed into a bent state when the platform dives; Figures 15 and 16 show a structural diagram of a balance bar with a water-blocking panel. The end of the balance bar (6) is also equipped with an arc-shaped water-blocking panel (6.1) to increase the resistance of the balance bar to swing. Figure 16 shows a hemispherical water-blocking panel (6.2), which is provided with an entry hole (6.11) for the balance bar. The balance bar is several meters long, preferably more than 6 meters. The swing of the floating platform (1) under the influence of wind and waves needs to overcome the resistance of the balance bar (6), the counterweight (62), and the water-blocking panel (61) to rise and swing. Therefore, this structure makes the platform level. As the sea level rises or dives, the amplitude of the swing under the influence of waves is small, and the balance of the platform and the water surface is automatically adjusted.

[0099] As shown in Figures 1 and 17, the rocker arm device includes a rocker arm power transmission member (21) and a rocker arm (22). The rocker arm is provided with a support hole (2.1). One end of the rocker arm device is pivoted to the support (14) of the floating platform on the water through the support hole (2.1). The end of the rocker arm (22) is the rocker arm power transmission member (21) and is connected to the rocker arm power receiving member (31) of the main shaft assembly. The main shaft (32) is equipped with a generator drive gear (33). The motor drive gear (33) is transmitted to the generator rotor, and the generator (4) outputs electricity. The main shaft (32) is fixed to the floating platform on the water by a support member 34. Specifically, the rocker arm is pivoted to the platform near the end. The end of the rocker arm is provided with an arc rack (21.1, 21.2). The rack is engaged with the gear of the main shaft to transmit the power of the rocker arm swing to the rotation of the main shaft.

[0100] As shown in Figures 17 and 18, the first and second rocker arm devices are shown. The rocker arm power transmission member (21) is provided with an inner arc rack (21.1) and an outer arc rack (21.2) at one end of the rocker. The distance between the inner arc rack and the outer arc rack is roughly equal to the diameter of the main shaft receiving the rocker arm power member gear set (31). The inner arc rack and the outer arc rack are opposite and staggered, respectively meshing with different gears of the gear set (31). The single-phase gear transmission directions of the gear set (31) corresponding to the inner arc rack and the outer arc rack are opposite. Therefore, the rocker arm (22) can drive the single-phase gear set (31) to rotate in the same direction when it is raised or lowered. The rack of the first rocker arm device is open, Figure 17, while the rack of the second rocker arm device is closed, Figure 18. The remaining structures are the same.

[0101] FIG19 shows a third type of rocker arm (23), which can be multiple and connected in directions other than the length. This structure is conducive to manufacturing a longer rocker arm and a rocker arm with high strength.

[0102] FIG20 shows a fourth type of rocker arm (27). Two or more rocker arm power transmission members (21) may be provided on one rocker arm (27). The end of the rocker arm is a Y-shaped fork, each fork having a support hole (2.11). The end of the rocker arm (27) is pivotally connected to the support (14) of the floating platform (1) through the support hole (2.11).

[0103] FIG21 shows a fifth type of rocker arm (24) having multiple sections. The rocker arm (24) includes three sections of telescopic tubes (24.1, 24.2, and 24.3). This structure can adjust the length of the rocker arm according to different wave spacings in different sea areas, thereby maximizing the swing amplitude of the rocker arm and maximizing the transmission force.

[0104] FIG22 shows a sixth type of rocker arm (26). The rocker arm 26 is composed of two sections, or more than two sections, and a rotating shaft (2.8) is provided at the connection. The two rocker arms (26) are pivotally connected via the rotating shaft (2.8).

[0105] The main shaft can be driven by multiple sets of rocker arm devices, and the rocker arms have different lengths. When one rocker arm is at the wave crest, another rocker arm is in the wave, and another rocker arm may be in the wave valley, the main shaft can be driven to rotate continuously.

[0106] As shown in FIG27 , a rocker arm device is provided with a rocker arm float (29) at the end of the rocker arm (22) extending toward the seawater. The end of the rocker arm can swing up and down according to the height of the waves. The rocker arm float (29) can be spherical, as shown in FIG24 , with a rocker arm (22) insertion slot (29.1) provided at its center; or rectangular, as shown in FIG25 , with an insertion slot (29.1) provided on the float. The rocker arm (22) passes through the installation slot (29.1) to install the rocker arm float (29) on the rocker arm (22). Similarly, the rocker arm float (29) can be hollow, with air and water inlets (29.2) and air and water outlets (29.3).

[0107] Figures 26 and 27 show another double-floating rocker arm device, which includes a rocker arm (22), a latch (22.1), a rocker arm float mounting frame (22.2), a toggle pin (22.3), and two rocker arm floats (291). A toggle groove (13.1) is provided on the support, and the toggle pin (22.3) is arranged in the toggle groove (13.1). A rotating shaft (22.21) is provided on the rocker arm float mounting frame (22.2) and inserted into the rocker arm hole. The rotating shaft (22.21) is inserted into the rocker arm hole (22.5). The arm float mounting frame (22.2) can rotate on the rocker arm (22). The arm float mounting frame (22.2) A stop block (22.23) is provided on the rocker arm float mounting (22.2). The rocker arm float mounting (22.2) is also provided with a latch hole (22.22). The latch (22.4) is parallel to the rocker arm (22) and is connected to the rocker arm (22). The latch and the rocker arm (22) can be moved in the longitudinal direction. That is, by pulling the toggle pin (22.42), the latch (22.4) can be pulled out of the latch hole (22.22). The float mounting frame (22.2) can rotate with the rocker arm (22). When the rocker arm (22) is rotated to the state shown in Figure 27, the stop block blocks the latch and the latch hole (22.22). The float mounting frame (22.2) is fixed to the rocker arm (22). The rocker arm assembly is shown in Figures 28 and 29.

[0108] FIG30 shows an embodiment of an expandable rocker arm float. A rocker arm float (292) is provided at the end of the rocker arm (22). The rocker arm float (292) is fixed on a float groove (292.1). The float groove (292.1) is connected to the rocker arm (22). Two float compression plates (292.2) are pivotally connected on both sides of the float groove (292.1) by a compression plate rotating shaft (292.3). When the waves are large, the float compression plates (292.2) are pushed upward by the waves and the float compression plates are retracted. When the waves are small, the float compression plates are unfolded to increase the buoyancy of the rocker arm float (292).

[0109] FIG38 shows that the floating platform on the water can dive, and its diving depth is: assuming that the wave wavelength is L, the diving depth of the platform is H, that is, H>30%L;

[0110] The main shaft transmission assembly (3) is shown in FIG39 and comprises: a main shaft (3), a rocker arm power receiving member (32), and a generator power transmitting member (33); a main shaft rotatable fixed plate (34) is mounted on a platform, and the main shaft (3) receives power from the rocker arm swinging with the waves and converts it into power to drive the main shaft to rotate, and the rotation of the main shaft drives the generator to generate electricity;

[0111] The main shaft can also be rotated to transmit the power to the generator at a variable speed or constant speed, and an inertia wheel may or may not be provided during the transmission process;

[0112] The main shaft transmission device is shown in Figures 40 and 41. The rocker arm power transmission component is as follows: an outer arc rack (21.1) and an inner arc rack (21.2) are provided at the inner end of the rocker arm; the rocker arm power receiving component includes at least two gears (32) on the main shaft; the outer arc rack (21.1) meshes with a gear on the main shaft; the inner arc rack (21.2) meshes with another gear on the main shaft, so that the rocker arm swings up and down to effectively transmit the swing kinetic energy to the main shaft rotation, and the main shaft rotation drives the generator to generate electricity;

[0113] Figures 42 and 43 show a schematic diagram of a dual generator: the first generator and the second generator are connected to the main shaft. When the rocker arm moves the rack (435) but does not move the push gear (434), the main shaft (31) only drives the first generator to generate electricity. When the rocker arm on the rocker arm moves the rack (435) and the push gear (434), the push rack (433) pushes the clutch lever (432) to make the clutch gear (431) engage the transmission mechanism of the second generator, so that the first generator and the second generator are in operation. 436 is a buffer pusher.

[0114] Figures 44 and 45 show the diving mechanism of the floating platform on water. The diving sequence of the floating platform on water is as follows: the platform is filled with water and dives - the floating body in the automatic angle adjustment device for the parallel line of the wave crest or trough is filled with water and dives - the rocker arm float is filled with water and the rocker arm rod is erected and dives;

[0115] The ascending sequence is: the rocker arm float is inflated and floated (the rocker arm rod is upward) ---- the wave crest or trough parallel line angle automatic adjustment device is inflated and floated ------ the platform is inflated and floated.

[0116] When the wave reaches the set wave level, the trigger tooth bar (16.1) turns the trigger gear to start energy storage. After the set number of consecutive turns, the diving trigger device (16) starts the latch (16.3) to retract, allowing the head of the balance rod (6) to remove the restriction and extend out of the platform, and at the same time triggers the platform float to deflate and take in water (11.1).

[0117] When the balancing bar (6) extends out of the platform, the balancing bar head (65) leaves the elastic pin member limiter (65), disengaging the restriction on the toggle member (16.4). After the elastic latch shaft (16.7) pops out, the rocker arm 2 dives into place, and the elastic latch shaft (16.7) is inserted into the rocker arm diving latch hole (16.8), thereby limiting the swing of the rocker arm.

[0118] Figures 46, 47 and 48 show a platform network consisting of multiple floating platforms on water, where two platforms are connected by a connector 9, which is provided with a limit mechanism 9.1 to prevent collision between the two platforms.

[0119] Two or more floating platforms on water can be connected by connecting pieces into one or more rows, and can be staggered or aligned;

[0120] Figures 49 and 50 show another method of converting the swing kinetic energy of the rocker arm into pressure kinetic energy for power generation, or into pressure energy, or raising the water potential energy:

[0121] When the rocker arm device (2) floats upward, the piston rod (713) toggle member will toggle the piston rod (712), and the piston rod (712) compresses the gas and liquid in the gas and liquid inlet (715) into pressurized gas and liquid. The pressurized gas and liquid flow out from the gas and liquid outlet (714) and are converted into pressure kinetic energy. A gas-liquid booster pump (71) is also provided in the piston chamber, and the pressure kinetic energy drives the generator to operate and generate electricity.

[0122] Example 2:

[0123] Figures 31 and 32 show a rocker arm float moving assembly with a traction rocker arm float ball installed on the rocker arm; an automatic wave walking device (8) is connected at both ends of the rocker arm float (29), and a rack (28) is provided on one side of the rocker arm (22).

[0124] The automatic wave-moving device is shown in Figure 36. The automatic wave-moving device (8) comprises a water inlet expansion (84), a cavity (89), a water outlet (82), an impeller (86), an impeller water inlet (85), and a rotating shaft (87). The automatic wave-moving device is installed on a rocker arm (22). By guiding or limiting a mechanism, the device can be floated on the water surface, and the opening is directed toward the water surface. The impeller water inlet (85) is arranged above the impeller (86) and is eccentric with the impeller rotating shaft (87). When the waves are at a high level, seawater enters the opening from above. The upper seawater falls and rotates due to being eccentric with the impeller rotating shaft (87). The impeller (86) is subjected to the impact of the water coming from above on the water inlet side. The rotating shaft (87) rotates and is driven by a transmission mechanism, and the automatic wave-moving device can be moved. Accompanying drawing 37 shows the trend path of the wave-moving device under large waves and small waves. Under large waves, the wave-moving device moves a longer distance.

[0125] Optimally, a one-way valve (88) is provided at the water outlet, which only allows the water in the cavity to be discharged, and the seawater cannot enter the cavity in the reverse direction; because the automatic wave-seeking walker is provided on the upper rocker arm, it is easy to set a guide or limit, so that the automatic wave-seeking walker can float or dive roughly perpendicular to the sea surface, rather than swinging left and right. The wave-seeking principle of the automatic wave-seeking walker:

[0126] When the waves are large: within a wave cycle, the inlet route of the automatic wave-tending walker is shorter than the outlet route; that is, the automatic wave-tending walker at the outer end of the integral rocker arm has a large draft, pulling the rocker arm float to automatically move outward;

[0127] When the waves are small: in one wave cycle, the inlet route of the automatic wave-tending walker is longer than the outlet route; that is, the automatic wave-tending walker at the inner end of the rocker arm has a large draft, pulling the rocker arm float to automatically move inward;

[0128] Based on the above principle, when the wave size changes, the automatic wave-trending walker pulls the rocker arm float to move toward the maximum height difference between the wave crest and the wave trough, thereby maximizing the rocker arm swing;

[0129] The same path can also maximize wave avoidance;

[0130] According to the above, the wave-seeking principle of the automatic wave-seeking walker can move the rocker arm float in the direction of maximizing the height difference between the wave crest and the wave trough as needed, thereby maximizing the rocker arm's heaving angle;

[0131] The rotating shaft output of the automatic wave-following walking device is shown in Figure 33. The rotating shaft (87) extends out of the cavity (89) and is equipped with a synchronous gear (81). The synchronous gear (81) is engaged with the rack (28) on the rocker arm. A roller (81.4) is also provided at the upper end of the synchronous gear. When the wave-following moving device (8) is on the sea surface and seawater flows into the opening (84), seawater rushes down the impeller (86) from the eccentric water inlet (85). The impeller (86) is pushed by the water inlet to rotate in the direction of the water inlet side. The rotating shaft (81) and the synchronous gear (81.1) thereon rotate synchronously. The synchronous gear (81.1) is engaged with the side rack (28) of the rocker arm. The roller (83) rolls on the other side of the rocker arm. Therefore, the wave-following moving device moves in the direction of the wave height on the rocker arm and moves on both sides of the rocker arm, so that the buoy can rise or fall roughly at the height of the wave crest, with the highest drop. A one-way valve (88) is provided on the water outlet (86) to prevent water from above from entering the cavity.

[0132] As shown in Figure 32, two automatic wave-tending walkers are symmetrically mounted on the two ends of the rocker arm float, which includes: the rocker arm float, two automatic wave-tending walkers (8), and a connecting rod (7). The two automatic wave-tending walkers are connected by the connecting rod (7). The rocker arm float (29) is arranged on the connecting rod. The water inlets (85) of the automatic wave-tending walkers (8) at the two ends are also symmetrical, that is, away from each other's side, or close to each other's side. Like this, the moving directions of the two automatic wave-tending walkers receiving water from above are opposite. The water inlets of the automatic wave-tending walkers at the two ends are arranged on the side away from each other. According to the water-tending and wave-tending properties of the automatic wave-tending walkers, when a certain automatic wave-tending walker has more water inflow, it will move to the side of the automatic wave-tending walker with more water inflow, and drive the two automatic wave-tending walkers and the rocker arm float to move on the rocker arm, (i.e., drive the rocker arm float moving mechanism assembly to move on the rocker arm) so that the rocker arm device swings with the changing waves, and stops moving when the swing angle is maximized.

[0133] That is, when the waves are big: the automatic wave-treading walker far away from the floating platform on the water has a large draft, and the floating body of the rocker arm is automatically moved outward by dragging it, so that the rocker arm can achieve maximum swing within half a wave cycle (half a wave cycle refers to the time required for the wave to pass through adjacent crests and troughs, which is called half a wave cycle).

[0134] That is, when the waves are small: the automatic wave-treading walker near the floating platform on the water has a large draft, and the rocker arm float automatically moves inward (retracts toward the platform) to maximize the rocker arm's ups and downs within half a wave cycle.

[0135] Figure 34 shows an automatic wave-chasing walking device with a dual-gear output. The extended end of the rotating shaft (81) is equipped with a synchronous gear (81.1); and a driven wheel (81.2). A roller (81.4) is also provided at the upper end of the synchronous gear. The synchronous gear (81.1) and the driven wheel (81.2) are engaged with the rack (28) of the rocker arm (22). The roller (81.4) is on the other side of the rocker arm. The cooperation of these three points stabilizes the wave-chasing moving device on the rocker arm, and the opening is positioned upward.

[0136] Figure 35 shows a wave-chasing device with a low-position rotating shaft output. The difference from Figure 40 is that a transmission wheel (81.3) is set below the synchronous gear, and the power is output through the rotating shaft of the transmission wheel (81.3). Since the transmission wheel is moved downward, this device has a lower position in the water and a higher impact force from the water above.

[0137] The above embodiments are only used to further illustrate a device of the present invention for maximizing the wall drop by tending to the wave height difference, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention fall within the scope of protection of the technical solution of the present invention.
