Description

Technical Field

[0001] The present invention relates to marine new energy engineering technology, and in particular to a tidal wave eliminating device. Background Art

[0002] With the accelerated development of offshore renewable energy, offshore photovoltaics, as an emerging green power generation method, is gradually moving from near-shore pilot projects to deep-sea deployment. However, due to the complexity of the marine environment, especially the combined effects of natural factors such as wind, waves, and tides, offshore photovoltaic systems face significant challenges in structural stability, safety, and operational maintenance during actual operation. Extreme wave phenomena such as wind loads from strong winds, high-frequency waves caused by strong winds, and occasional tsunamis caused by earthquakes can all significantly impact and damage photovoltaic modules, support foundations, and supporting power systems, limiting the ability of offshore photovoltaic installations to continue operating and their economic applicability in harsh sea conditions.

[0003] Existing offshore photovoltaic projects generally rely on reinforced pile foundations, enhanced buoys, or breakwaters to enhance their wind and wave resistance. However, these measures are not only labor-intensive and costly, but also have limited effectiveness in mitigating wave energy. They often rely on passive mitigation measures, failing to actively utilize and coordinate the control of natural energy. Summary of the Invention

[0006] The beneficial effects of the present invention are: providing a tidal wave-breaking device, which uses an impact plate to resist the impact caused by tidal phenomena, avoiding the equipment itself from being directly impacted by waves, and at the same time, the impact plate is provided with a first connecting rod hinged to the mounting shell, which can swing by itself to absorb the impact force when impacted by waves, avoiding rigid resistance to reduce the life of the impact plate, and at the same time, a second connecting rod with an elastic part is provided, and when the impact plate swings, the elastic part provides a rebound force to assist the impact plate in resetting, thereby prompting the impact plate to continue to swing and avoid jamming; that is, the swingable and resettable impact plate is used to absorb and weaken the waves caused by tidal phenomena, thereby reducing the damage to offshore equipment.

[0008] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0009] Please refer to Figures 1 to 3 , a tidal wave eliminating device, comprising a wave eliminating component 1 and a mounting shell 2; The wave-breaking assembly 1 includes an impact plate 11, a first connecting rod 12, a second connecting rod 13 and an elastic member 14; one end of the first connecting rod 12 is connected to the mounting shell 2, and the other end is hinged to the impact plate 11, and the impact plate 11 can swing around the hinge point of the first connecting rod 12 in a horizontal plane; one end of the second connecting rod 13 is connected to the impact plate 11, and the other end is movably connected to the elastic member 14, and the elastic member 14 is connected to the mounting shell 2 and is used to provide rebound force during the swinging of the impact plate 11.

[0010] As can be seen from the above description, the beneficial effect of the present invention is that by setting the impact plate 11 to be hinged with the first connecting rod 12 and allowing the impact plate 11 to swing around the hinge point, the impact plate 11 is no longer a rigid fixed structure from a structural principle, but has a certain degree of adaptive mobility. When a tidal wave impacts the impact plate 11, the horizontal component of force generated by it causes the impact plate 11 to swing at the hinge point, thereby converting part of the impact energy into mechanical kinetic energy, and achieving active absorption and elimination of wave impact. At the same time, the device is also provided with a second connecting rod 13 and an elastic member 14, wherein the elastic member 14 is connected between the mounting shell 2 and the second connecting rod 13, and provides a rebound force during the swinging process of the impact plate 11. This rebound force not only helps the impact plate 11 to quickly reset after the wave action ends, maintains the initial state of the structure, and prevents the structure from being offset or unbalanced for a long time, but also enables the impact plate 11 to further dissipate the wave impact during the reciprocating motion, thereby enhancing the overall wave-breaking effect. This composite structure utilizing the swing absorption of the impact plate 11 and the reset assistance of the elastic member 14 avoids the fatigue damage problem caused by direct head-on collision between traditional rigid wave breakers and waves, and significantly improves the reliability and service life of the device.

[0011] In some embodiments, the hinge position between the first connecting rod 12 and the impact plate 11 is located in the middle area of the impact plate 11, the number of the second connecting rods 13 is at least two, and the plurality of second connecting rods 13 are respectively arranged on both sides of the width direction of the impact plate 11.

[0012] It can be understood that the middle area of the impact plate 11 refers to the area near the center line of the impact plate 11 in the width direction. By being hinged here, the impact plate 11 can be swung in the horizontal plane.

[0013] As can be seen from the above description, the hinge point of the first connecting rod 12 is further defined as being located in the middle region of the impact plate 11, and multiple second connecting rods 13 are introduced, one on each side of the impact plate 11 in its widthwise direction. The principle behind this structure is that by placing the hinge point in the middle of the impact plate 11, it can swing more balanced left and right, or approximately left and right, around its central axis when impacted by waves. This ensures a symmetrical and stable swing path, avoiding uneven swinging or structural overloading caused by offset support points. The multiple second connecting rods 13 provide bilateral support for the impact plate 11, ensuring that the impact plate 11 maintains balanced force under varying wave directions, preventing excessive force on one side from causing structural torsion or damage to the connectors. Furthermore, this multi-point arrangement improves the stability of the elastic member 14's return control of the impact plate 11, enabling it to rebound more quickly and smoothly after being stressed, thereby enhancing its fatigue resistance under continuous wave action. This structure effectively enhances the device's overall wave resistance and mechanical stability, improving weathering resistance and long-term performance.

[0014] Please refer to Figures 1 to 4 In some embodiments, the wave-breaking assembly 1 further includes a pendulum 15, a cable 16 and a power generation unit 17; the pendulum 15 is arranged inside the mounting shell 2; there are two cables 16, one cable 16 connects the pendulum and one end of the impact plate 11 in the height direction, and the other cable 16 connects the pendulum and the other end of the impact plate 11 in the height direction, and the power generation unit 17 is used to generate electricity during the movement of the pendulum 15.

[0015] As can be seen from the above description, a combined structure of a pendulum 15, a cable 16 and a power generation unit 17 is introduced. The core principle is to transmit the swinging motion of the impact plate 11 to the pendulum 15 in the shell through the cable 16, thereby driving the pendulum 15 to undergo mechanical displacement and realize the conversion of mechanical energy. In this process, since the pendulum 15 is a gravity-driven component, it will form a periodic up and down or swinging motion inside the shell after being pulled, driving the power generation unit 17 to generate energy output. This makes the external disturbance of tidal impact become a usable mechanical energy resource, improving the flexibility and stability of energy conversion. This structure uses the periodic and predictable characteristics of ocean waves to realize the active capture and utilization of tidal energy, improve the energy self-sufficiency rate of the device, and provide auxiliary power support for offshore equipment. It is a multifunctional integrated structure that takes into account both wave breaking and power generation.

[0016] Specifically, the two cables 16 are provided with a joint portion 161 , and the two cables are integrated into one at the joint portion 161 and connected to the pendulum 15 through an integrated structure. The joint portion is located inside the mounting housing.

[0017] From the above description, it can be seen that since only one pendulum is set in the installation shell, when two cables are connected to the pendulum, it will cause wiring confusion and easily cause interference between the cables. Based on this technical problem, in this embodiment, a joint is set in the two cables, and the two cables after the joint are combined into one and connected to the pendulum. Since the impact plate swings up and down, only one cable will drive the pendulum to lift, and the other cable will be in a relaxed state. Therefore, the integrated design after the joint can stably achieve the lifting of the pendulum and ensure that the two cables do not interfere with each other, while simplifying the spatial layout and reducing installation costs.

[0018] Specifically and preferably, the power generation part 17 includes a worm 172 and a turbine generator 171, the worm 172 is concentrically connected to the integral area of the cable 16, the worm 172 is transmission-connected to the turbine generator 171, and the pendulum 15 generates electricity through the turbine generator 171 during its up and down movement.

[0019] The above description further clarifies that the power generation unit 17 comprises a worm gear 172 and a turbine generator 171, and indicates that the pendulum 15 generates electricity within the unit during its up-and-down motion. The principle is that the impact plate 11, when it swings up and down, or nearly so, drives the cable 16 and the weight to swing up and down. During the up-and-down motion of the pendulum 15, the turbine worm gear 172 generates electricity. By integrating this structure into the tidal wave-breaking device, the device not only reduces waves but also effectively recovers wave energy, effectively improving the energy efficiency and autonomous operation capabilities of marine engineering equipment. This compact structure is adaptable to complex marine environments. In some embodiments, the power generation component also includes a receiving plate 173, which is arranged inside the mounting shell 2 and is used to receive the pendulum 15. When the impact plate 11 is not swinging, the weight of the pendulum 15 is borne by the receiving plate 173. When the pendulum 15 is pulled up, it separates from the receiving plate 173. At this time, the impact plate 11 can be reset by relying on the weight of the pendulum 15 to avoid the impact plate 11 from getting stuck at a certain point; that is, two receiving plates 173 are provided to limit the pendulum 15. When one pendulum 15 is pulled up, the other pendulum 15 is received by the receiving plate 173. At this time, the impact plate 11 is reset by relying on the weight of the pendulum 15, and the self-reset function is realized while generating electricity.

[0020] Please refer to Figures 1 to 3 In some embodiments, the elastic member 14 includes a spring 141 and a third connecting rod 142; the spring 141 is sleeved on the third connecting rod 142, one end of the spring 141 is hinged to the second connecting rod 13, and the other end is movably connected to the third connecting rod 142, and the third connecting rod 142 is hinged to the mounting shell 2.

[0021] As can be seen from the above description, a combined structure of a spring 141 and a third connecting rod 142 is introduced, and the spring 141 is sleeved on the third connecting rod 142. The structural principle is to store the kinetic energy generated by the swing of the impact plate 11 through the deformation of the spring 141, and release the kinetic energy in the form of elastic force after the wave force subsides, thereby assisting the impact plate 11 to quickly rebound to its original position. The hinged connection between the spring 141 and the second connecting rod 13 allows the spring 141 to undergo linear or nonlinear compression deformation with the swing angle, achieving a dynamic response that is more in line with the wave impact cycle. The spring 141 and the third connecting rod 142 are movably connected to ensure that appropriate elastic force feedback can be obtained under different swing amplitudes, effectively preventing impact damage caused by the rigid structure. In addition, the design in which the above-mentioned spring 141 is hinged to the second connecting rod 13, and the third connecting rod 142 is hinged to the mounting shell 2, can adapt to mounting shells 2 of different shapes. The principle lies in the way in which the spring 141 is hinged, which can adapt to different installation positions and different installation angles. During the swinging process of the second connecting rod 13, it can provide rebound force. This elastic system not only improves the overall flexible response capability of the device, but also enhances the structural durability and wave absorption range, providing a more lasting and effective protection means in tidal environments.

[0022] Specifically, the third connecting rod 142 is provided with a push plate 143 , the push plate 143 is slidably connected to the third connecting rod 142 , and one end of the spring 141 is fixedly connected to the push plate 143 .

[0023] As can be seen from the above description, the structure of the third connecting rod 142 has been optimized, and a sliding push plate 143 has been added thereto, with one end of the spring 141 fixedly connected to the push plate 143. The core principle of this structure is to adjust the compression position of the spring 141 by sliding the push plate 143, thereby achieving the controllability of the preload force or elastic force range of the spring 141. The sliding connection between the push plate 143 and the connecting rod allows the user to independently adjust the initial stress state of the spring 141 according to the different tidal intensities or the swing amplitude requirements of the impact plate 11, thereby improving the system's adaptability to different sea conditions. This adjustable buffer system greatly enhances the flexibility of the device, allowing it to maintain a stable wave-breaking effect and good reset characteristics when facing waves of different periods and energy levels. In addition, the structure of the sliding push plate 143 enables module replacement and maintenance, which also improves the maintainability of the entire machine and its ability to adapt to complex marine environments. The adjustment method of the push plate 143 position can be manually preset or electrically controlled using signal transmission.

[0024] In some embodiments, the wave-breaking assembly 1 includes at least two extension plates 18, which are symmetrically arranged and slidably connected to the impact plate 11. The first connecting rod 12 is hinged to the impact plate 11, and the second connecting rod 13 is connected to the extension plates 18. The extension plates 18 are used to expand the contact area between the impact plate 11 and the waves. When wave breaking is required, the extension plates 18 slide and extend from both ends of the impact plate 11 in the width direction. When idle, the extension plates 18 slide and are stored inside or outside the impact plate 11. The retractable extension plates 18 are extended to break waves under special working conditions and stored when idle to avoid device wear and increase the service life of the device. At the same time, the through hole 21 of the mounting shell 2 that cooperates with the second connecting rod 13 is an oblong hole, the purpose of which is to assist the sliding of the second connecting rod 13 connected to the extension plate 18 during the sliding process, thereby preventing the second connecting rod 13 from interfering with the mounting shell. Preferably, the covering angle of the extension plate 18 after deployment is between 100-150°, preferably 120°.

[0025] Please refer to Figure 5 In some embodiments, a turbine assembly 3 is further included; the mounting shell 2 is a cylindrical shell; the turbine assembly 3 is provided at one end of the cylindrical shell located underwater, and the turbine assembly 3 rotates to generate electricity based on the tidal process.

[0026] As can be seen from the above description, it is proposed to set a turbine assembly 3 at the underwater end of the installation shell 2 to realize the function of rotational power generation. The technical principle is based on the tidal process to form a stable flow in the seawater, which drives the underwater turbine blades to rotate. The cylindrical shell is conducive to the introduction of seawater flow and stabilizes the direction of the water flow, thereby improving the working efficiency of the turbine. The turbine rotates under the flow of seawater, and converts kinetic energy into electrical energy through the connected power generation structure, realizing the direct utilization of tidal flow energy. This structural layout is compact and relies on natural ocean currents. It does not require external power drive and can continuously provide auxiliary energy to provide stable power supply for offshore platforms, sensors or communication equipment. The integration of tidal energy conversion and wave-breaking structure not only realizes the multifunctional integration of equipment, but also greatly improves the energy output ratio and practicality of the device per unit volume.

[0027] Specifically, the turbine assembly 3 includes a first turbine 31 and a second turbine 32 . The first turbine 31 and the second turbine 32 are both rotatably connected to the mounting housing 2 . The blades of the first turbine 31 and the second turbine 32 face in opposite directions.

[0028] As can be seen from the above description, the turbine assembly 3 has been refined to include a first turbine 31 and a second turbine 32 with blades facing in opposite directions. This structural principle exploits the periodic ebb and flow of tidal flow, where the direction of the water flow reverses within a cycle. The two turbines with oppositely oriented blades can each take over power generation during high and low tide, achieving bidirectional power generation. The differing blade orientations ensure that one turbine is always rotating under load regardless of the direction of the water flow, ensuring uninterrupted power generation and significantly improving the utilization and stability of the power generation system. Furthermore, this dual-turbine layout maintains balanced loads, reducing casing deflection or structural fatigue caused by unilateral operation, improving the overall stability and service life of the system, and ensuring excellent tidal adaptability and continuous power output. In some embodiments, the blade pitch angles of the first turbine 31 range from 30-50°, and the blade pitch angles of the second turbine 32 range from 50-80°, with the first turbine 31 positioned above the second turbine 32.

[0029] At the same time, the outer cover of the turbine assembly 3 is provided with a filtering device to prevent mud and sand in the ocean current from damaging the blades.

[0030] Please refer to Figure 6 In some embodiments, a foldable wind turbine blade 21 is provided on the top of the mounting shell 2 .

[0031] As can be seen from the above description, foldable wind turbine blades 21 are added to the top of the mounting housing 2. The technical principle of this structure is to utilize the perennial offshore wind resources at the top of the device to generate additional power. Because tidal phenomena often occur during typhoon weather, the foldable blades can be folded when the wind is too strong to prevent blade damage or excessive structural vibration that affects the stability of the device. At the same time, they can be unfolded to generate electricity when the wind is moderate, forming a multi-source power generation structure that complements the underwater turbine power generation and the pendulum 15 power generation system within the housing. This vertically integrated design significantly improves the device's ability to capture and utilize multiple natural energies, allowing a single device to undertake multiple energy output tasks and reduce external power supply pressure.

[0032] In some embodiments, the wave-breaking component 1 is arranged on the mounting shell 2 of the offshore wind turbine. In order to achieve combined wave breaking, a wave-breaking array is set up to protect other facilities behind the wave-breaking array. For example, at least three rows of wave-breaking "walls" are set up, that is, each row is provided with multiple wind turbines at a preset interval, and each wind turbine is provided with the above-mentioned wave-breaking component 1. Each row of wave-breaking walls is staggered, so that multiple rows of wave-breaking walls are used to weaken the waves caused by tidal phenomena in extreme weather conditions, and use tidal energy to generate electricity, while protecting other facilities behind the wave-breaking walls.

[0033] The tidal wave-breaking device provided by the present invention achieves the synergistic goals of efficient reduction of tidal waves and energy utilization through the adaptive swing and energy recovery mechanism of the impact plate, and has good application prospects and practical engineering value. The impact plate in the device is not a traditional rigid structure, but is hinged to the first connecting rod so that it can swing freely around the hinge point, thereby having a flexible response capability of absorbing energy and reducing pressure under the impact of waves. This structure can not only effectively reduce the direct impact force of waves and reduce the risk of equipment fatigue, but also, with the help of the second connecting rod and elastic member connected between the impact plate and the mounting shell, provide a stable rebound force during the swinging process of the impact plate, further enhancing the recovery ability and cyclic response performance of the wave-breaking structure.

[0034] To enhance structural stability and swing symmetry, the first connecting rod's hinge point is located in the center of the impact plate, with multiple second connecting rods positioned on either side. This ensures uniform force distribution and a balanced motion trajectory, effectively preventing structural distortion or component damage caused by eccentric impact loading. The through-hole structure in the mounting housing not only provides a reasonable guide path for the connecting rods, preventing motion interference, but also facilitates system modularization and maintenance operations, enhancing the industrial feasibility and reliability of the structure while ensuring functional implementation.

[0035] Furthermore, the device incorporates a design that converts wave kinetic energy into electrical energy. This is achieved by connecting a pendulum and a cable to a fourth connecting rod, transmitting the impact plate's swinging motion to the internal pendulum, guiding it in periodic up-and-down motion. This is then generated via the turbine and worm gear components housed within the mounting housing, significantly improving the device's energy efficiency. Furthermore, a turbine assembly, aligned with the tidal current, is located at the bottom of the housing. A dual-turbine reverse-blade structure enables bidirectional power generation at both high and low tides, ensuring stable energy output regardless of the tidal current, enhancing the continuity of power production and its environmental adaptability.

[0036] The top of the device features a foldable wind turbine blade structure, allowing it to simultaneously utilize wind energy for power generation when wind speeds are favorable, while flexibly retracting to avoid structural damage in strong winds. This vertically integrated multi-source power generation mechanism effectively leverages marine natural resources such as tidal, wave, and wind energy, maximizing space utilization efficiency and optimizing energy harvesting. This provides continuous and stable power for applications such as offshore island power supply, navigation lights, and offshore monitoring platforms.

[0037] In summary, the present invention not only provides a wave-resistant system that is structurally high-strength, flexible, and modular, but also functionally realizes the coordinated utilization and conversion of wave energy and electrical energy, effectively enhancing the environmental adaptability, durability, and energy self-sufficiency of the device.

[0038] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's description and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
