Abstract
Description
Technical Field
[0001] The present invention relates to the field of wind power technology, and in particular to a wind power system integrating wind power, wave power generation and aquaculture equipment. Background Art
[0002] As the development of marine resources accelerates, offshore wind power, a core area of the clean energy industry, is experiencing large-scale development. However, traditional offshore wind power platforms, with their sole function of generating electricity, face bottlenecks such as low sea area utilization. At the same time, the decline of offshore fishery resources has driven a surge in demand for the construction of modern marine ranches, and the conflict between wind power facilities and the aquaculture industry in the sea area is becoming increasingly prominent. In existing technologies, offshore wind power infrastructure only serves to support the wind turbines, typically using horizontal-axis wind turbines and / or vertical-axis wind turbines for power generation, leaving the underwater sea area underutilized. Although some proposals have attempted to add simple aquaculture functions to wind power platforms, they have failed to achieve deep synergy between energy production and ecological aquaculture, citing issues such as oxygen supply difficulties. Furthermore, renewable energy sources such as wave energy and wind energy have yet to form a multi-source complementary utilization system, resulting in low overall energy efficiency for the platforms. Because the airflow on the ocean surface can change at any time due to the impact of high tide waves and the dispersion of low tide waves, in the existing technology, traditional vertical axis wind turbines generally adopt a fixed angle of attack design, and the inclination angle of their blades cannot be adjusted during operation. This inherent defect leads to loss of aerodynamic performance. For example, when the waves hit the vertical tide, the fixed angle of attack causes the flow separation on the surface of the vertical axis wind turbine blades to intensify, and the wind turbine cannot fully capture the energy of strong winds; when the tide is falling, the excessive angle of attack induces a stall effect, reducing the blade speed and power generation efficiency; although the current marine wind power field attempts to introduce real-time electronic pitch systems to adjust the angle of attack, such active control schemes rely on precision sensors and hydraulic servo mechanisms, and failures are frequent in harsh marine environments with salt spray, high humidity, and wave impact.
[0003] Therefore, in view of this, the inventors proposed a wind power system that integrates wind power, wave power generation and aquaculture equipment to solve the above technical problems. Summary of the Invention
[0004] The purpose of the present invention is to provide a wind power system that integrates wind power, wave power generation and aquaculture equipment to solve the problems of insufficient coordination between energy production and ecological aquaculture on traditional offshore wind power platforms, and the inability to drive the vertical axis wind turbine to rotate according to the angle of attack of wave energy.
[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A wind power system integrating wind power, wave power generation and aquaculture equipment, comprising a wind power platform, aquaculture boxes and vertical power generation devices. The aquaculture boxes are installed in the middle of the wind power platform, and the vertical power generation devices are distributed around the wind power platform. The vertical power generation device includes a buoy assembly and a vertical power generation assembly, and the vertical power generation assembly is arranged above the buoy assembly; The vertical power generation assembly includes an outer rod, an inner rod, a base, and a plurality of blades. One end of the outer rod is connected to the buoy assembly, and the other end of the outer rod is connected to the base. The inner rod is arranged inside the outer rod and can slide inside the outer rod to drive the blades to change their angle of attack. The buoy assembly includes a cylinder, a sliding ring and a push rod. The bottom of the cylinder is submerged below the liquid surface to allow waves to enter and exit the cylinder. The push rod is fixed above the sliding ring, and the top of the push rod extends to the inside of the outer rod and is connected to the inner rod.
[0006] The wave drives the sliding ring to perform periodic lifting motion along the cylinder, and then drives the inner rod to slide synchronously inside the outer rod through the push rod, so that the attack angle of each fan blade changes adaptively.
[0007] Furthermore, the outer rod includes a bottom rod and a top rod rotatably connected to the bottom rod, a power generation disk is provided between the bottom rod and the top rod, the bottom of the bottom rod is fixedly mounted on the top of the cylinder, the top of the bottom rod is connected to the power generation disk, and the top of the top rod is fixedly connected to the base body.
[0008] Furthermore, each of the fan blades is distributed around the base body, and each of the fan blades is rotatably connected to the base body, and an angle of attack rod is eccentrically hinged on the fan blade; An attack angle adjustment frame is provided on the top of the seat body, the attack angle adjustment frame is connected to the top of the inner rod, and the free end of each attack angle rod is connected to the attack angle adjustment frame.
[0009] According to the above technical solution, when the sliding ring in the wave-driven cylinder rises and falls, the push rod drives the inner rod to slide up and down inside the outer rod; the angle of attack adjustment frame at the top of the inner rod is displaced accordingly, pulling the eccentrically hinged angle of attack rods on each fan blade to move synchronously; the pulling action of the angle of attack rod forces all the fan blades to rotate around their rotating connection points with the seat body, thereby changing the direction of the airflow kinetic energy of the fan blades in real time. In this process, the split bottom rod and top rod in the outer rod transmit rotational torque through the power generation disk: the bottom rod is fixed to the cylinder to transmit the wave excitation force, and the top rod supports the seat body to bear the aerodynamic load of the fan blades. The power generation disk between the two converts the axial vibration energy in the angle of attack adjustment process and the mechanical energy of the fan blades rotated by the wind into electrical energy output, realizing the continuous power generation capability of the vertical axis power generation device in the adaptive angle of attack adjustment state.
[0010] Furthermore, the wind power platform is provided with a power generation element and a plurality of wave power generation components, and each of the wave power generation components is connected to the power generation element; The power generation component includes a rotating component and a generator. The rotating component is connected to each of the wave power generation components, and the rotating component is connected to the generator to drive the generator to work.
[0011] Furthermore, the rotating member includes a fixed cylinder, a rotating shaft and a plurality of worm gear fans arranged on the rotating shaft, a water inlet interface is formed at one end of the fixed cylinder, a water outlet interface is formed at the other end of the fixed cylinder, the rotating shaft is rotatably installed in the fixed cylinder, one end of the rotating shaft extends out of the fixed cylinder and is connected to an oxygen enrichment impeller, and the other end of the rotating shaft is connected to the generator.
[0012] According to the above technical solution, the floating body undergoes periodic lifting and lowering displacement under the action of sea waves. This movement is converted into a reciprocating compression stroke of the piston column within the suction chamber through a lever transmission mechanism (composed of a first rod body, a second rod body, and a hinged fulcrum). When the piston column moves upward, a negative pressure zone is formed in the suction chamber. Under the action of the pressure differential, seawater pushes open the first one-way valve and is sucked into the suction chamber through the water inlet pipe. When subsequent wave crests push the floating body downward, the piston column strongly compresses the water in the suction chamber, causing the pressurized water to push open the second one-way valve and be discharged at high speed through the water outlet pipe. The high-speed water output by multiple wave power generation components converges through parallel pipelines to the water inlet interface of the fixed cylinder, forming concentrated impact kinetic energy within the narrow flow channel of the fixed cylinder, strongly driving the worm fan assembly to rotate. The coaxial rotating shaft of the worm fan achieves two functional couplings during this process: First, the end of the rotating shaft is directly connected to the generator rotor, converting the kinetic energy of the wave and water flow into stable electrical output; second, the opposite extension of the rotating shaft passes through the fixed cylinder seal structure to connect to the aeration impeller. As the impeller rotates with the shaft, it creates a strong vortex shear effect in the oxygen-rich water, efficiently drawing surface air into the deeper water, generating a dynamic water flow rich in dissolved oxygen, which is then ejected into the aquaculture tank through the water outlet. This mechanism cleverly utilizes a single drive shaft to simultaneously complete the two-stage energy conversion chain—preferably converting captured wave energy into high-quality electricity and directly converting the remaining mechanical energy into ecological support, achieving a passive and coordinated operation of energy production and ecological conservation.
[0013] Furthermore, the wave power generation assembly includes a suction cylinder fixedly arranged on the wind power platform, a suction chamber is formed in the suction cylinder, a piston column is sealingly and slidably connected to the suction chamber, the top of the piston column is movably connected to a first rod body, the free end of the first rod body is connected to a second rod body, the free end of the second rod body is movably connected to a floating body, and a third rod body is fixedly arranged on the wind power platform, and the top of the third rod body is hinged to the middle position of the second rod body; The suction chamber is connected with a water inlet pipe and a water outlet pipe, the water inlet pipe is provided with a first one-way valve, the water outlet pipe is provided with a second one-way valve, the water inlet pipe extends below the liquid level, and the water outlet pipe is connected with the water inlet interface.
[0014] According to the above technical solution, the wave power generation assembly converts wave energy into water pressure energy through a float, a lever mechanism, and a piston system. Its specific working process is as follows: the float generates vertical displacement with the rise and fall of waves, driving the second lever body to form a lever movement with the hinge point of the third lever body as the fulcrum. The second lever body, in conjunction with the first lever body, pulls the piston rod to reciprocate within the suction chamber. When the float body rises, the piston rod moves upward to create negative pressure in the suction chamber, and seawater is sucked in through the inlet pipe equipped with a first one-way valve. When the float body falls with the trough of the wave, the lever acts in reverse to force the piston rod downward, increasing the pressure of the water in the chamber and opening the second one-way valve. High-pressure water is continuously output through the outlet pipe to the fixed cylinder. The lever mechanism converts the periodic rise and fall of the waves into linear compression of the water by the piston rod. The two one-way valves cooperate to form a directional fluid path, ensuring that water can only be drawn in through the inlet pipe and forced out through the outlet pipe, thereby generating continuously pulsating water pressure energy that is transmitted to the worm gear power generation system.
[0015] Furthermore, each of the floating bodies is in an arc-shaped structure, and each of the floating bodies is surrounded by the outer periphery of the wind power platform.
[0016] According to the above technical solution, multiple arc-shaped floating bodies are closely arranged around the periphery of the wind turbine platform, and their curved contours form a uniform buffer interval with the edge of the breeding box, avoiding local stress concentration caused by the straight-edge structure; when the floating body moves with the waves, the curved surface guides the water flow to diffuse smoothly along the curvature, significantly weakening the direct impact of turbulence on the breeding box; at the same time, the continuous closed structure formed by the arc array enhances the uniformity of the overall buoyancy distribution of the platform, effectively dissipates energy through collective undulating motion under the coupling of wind and waves, and suppresses the risk of platform capsizing.
[0017] Furthermore, a wave intake opening is provided on the side wall of the cylinder; each wave intake opening corresponds to a gap between adjacent floating bodies.
[0018] According to the above technical solution, the wave inlet openings on the side walls of each cylinder precisely correspond to the gaps between adjacent circular floats. When waves surge toward the platform, the gaps between the floats act as natural wave-gathering troughs, channeling the wave energy into the openings. The wave beams passing through the gaps are directly channeled into the cylinder cavity before they decay, effectively driving the sliding ring to rise. This design maintains the enhanced platform stability provided by the surrounding float structure while preventing the group of floats from obstructing the wave's incoming path, ensuring that the cylinder can continuously receive high-intensity water flow input to drive the internal rod lifting and adjustment mechanism.
[0019] Furthermore, the gaps between adjacent floating bodies form a V-shaped wave-gathering channel, and guide plates are provided at both ends of each floating body, and the guide plates extend to the wave inlet opening of the cylinder to form a wave acceleration guide structure; A rotating shaft is rotatably arranged between two adjacent guide plates, a linked water turbine is provided on the rotating shaft, and a circulating pump is coaxially connected to the main shaft; a water distribution pipe is connected to the water outlet of the circulating pump, and the water distribution pipe extends into the breeding box.
[0020] According to the above technical solution, when waves surge toward the platform, the V-shaped gaps between adjacent circular buoys form a natural wave-gathering channel, where the waves are gradually compressed and accelerated. Guide plates at either end of the buoys extend inward with smooth curves to the wave inlet opening of the cylinder, forming an unpowered fluid accelerator. This precisely directs the focused, high-speed water flow into the cylinder to drive the sliding ring upward and downward, while ensuring that some high-speed residual flow continues to flow through the gaps between the guide plates. Within this gap, a rotating shaft installed between adjacent guide plates carries turbine blades. The high-speed flow drives the shaft to rotate and output power. This shaft is directly connected to the main shaft of the circulating pump via a rigid coupling, converting the kinetic energy of the water into mechanical energy without loss. The circulating pump presses deep, oxygen-rich seawater through a network of water distribution pipes into the bottom nozzles of the aquaculture tank, creating an upwelling that promotes the removal of pollutants. Simultaneously, surface water is continuously pumped into the purification zone to complete water-gas exchange, forming a closed ecological cycle without external energy consumption. During the entire process, the wave-gathering and flow-guiding structure acts as both a wave energy capture amplifier and a fluid transmission channel. Ultimately, through coaxial mechanical linkage, it directly converts natural wave energy into a driving force for aquaculture water purification, breaking through the bottleneck of traditional aquaculture systems relying on external energy supply.
[0021] Furthermore, a support shaft is provided on the top of the wind power platform, and a horizontal axis wind turbine is provided on the top of the support shaft.
[0022] Beneficial effects of the present invention: The present invention changes the angle of attack of the vertical axis wind turbine driven by waves. The lifting power generated by the waves rushing into the cylinder is directly converted into the driving force for adjusting the angle of attack of the fan blades. This mechanism breaks through the reliability bottleneck of traditional electronic variable pitch systems in corrosive marine environments. It can not only improve the aerodynamic efficiency of the vertical wind turbine to a level that can adapt to non-steady-state wind fields, but also completely avoid failure modes such as sensor failure and hydraulic leakage caused by salt spray erosion, and construct a self-sustaining efficiency-enhancing system without external power supply and electronic control.
[0023] The wave mechanical energy captured by the float drives a piston pump to generate high-pressure water flow, which impacts the worm gear fan assembly, synchronously rotating the generator rotor and the aeration impeller. The generator converts this energy into clean electrical output, while the coaxial aeration impeller uses the remaining mechanical energy to forcibly dissolve air in the water, generating an oxygen-rich flow that is sprayed to the bottom of the aquaculture tank. This coaxial dual-output structure forms a closed energy metabolism loop: it efficiently converts wave energy into electricity and directly converts it into life-support power for the aquaculture system, ensuring the self-sustaining operation of the marine ecosystem.
[0024] The functional reuse architecture of wave and wind energy infrastructure features an array of arc-shaped floats surrounding the platform, acting as wave-resistant and flow-stabilizing structures to mitigate the impact of turbulence on the aquaculture tanks. Their V-shaped gaps create natural wave-gathering channels, guiding waves efficiently into the cylinder. An extended guide vane system further accelerates water flow, directly driving the linked turbines and simultaneously driving the circulating pump to enhance aquaculture water treatment capacity. The precise alignment of the cylinder's sidewall wave inlet and the gaps between the floats creates a fluid dynamics synergy between the wave capture system and the wind turbine cluster. This integrated design not only achieves the three-dimensional symbiotic utilization of wind energy, wave energy, and aquaculture space within a unit sea area, but also triggers multi-physics synergy through structural coupling, allowing energy devices and environmental factors to serve as mutually reinforcing carriers.

DETAILED DESCRIPTION
[0028] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.
[0029] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.
[0030] This embodiment proposes a wind power system that integrates wind power, wave power generation and aquaculture equipment. Figures 1 to 11 As shown, it includes a wind power platform, aquaculture boxes and a vertical power generation device. The wind power platform floats on the sea, the aquaculture boxes are installed in the middle of the wind power platform, the aquaculture boxes are used to breed aquatic fish, and the vertical power generation devices are distributed around the wind power platform.
[0031] like Figure 6 、 Figure 7 and Figure 8 As shown, the vertical power generation device includes a buoy assembly and a vertical power generation assembly, and the vertical power generation assembly is arranged above the buoy assembly; the vertical power generation assembly includes an outer rod, an inner rod, a seat body and a plurality of fan blades, one end of the outer rod is connected to the buoy assembly, and the other end of the outer rod is connected to the seat body, the inner rod is arranged inside the outer rod, and the inner rod can slide inside the outer rod to drive the attack angle of each fan blade to change.
[0032] The buoy assembly consists of a cylinder, a sliding ring, and a push rod. The cylinder's sidewalls feature a wave-intake opening, while its bottom is open and submerged below the liquid surface, allowing waves to enter and exit the cylinder. The push rod is fixed to the top of the sliding ring, with its top extending into the interior of the outer rod, where it is rotatably connected to the inner rod. Waves drive the sliding ring to periodically rise and fall along the cylinder, which in turn, through the push rod, drives the inner rod to synchronously slide within the outer rod, resulting in adaptive changes in the angle of attack of each blade.
[0033] It should be noted that the core mechanism of the wave-driven sliding ring's cyclical rise and fall stems from the hydrodynamic response of the cylinder structure and the mechanical conversion of wave energy. When waves approach the wind turbine platform, seawater simultaneously flows into the cylinder cavity through the bottom opening and the side wall wave inlet. The water forms an instantaneous upwelling within the cylinder of limited cross-section. Its buoyancy and the fluid impact force work together to propel the sliding ring upward, overcoming its own weight. As the wave crest passes, the water in the cylinder rapidly falls back due to gravity and discharges into the ocean through the bottom opening. At the same time, the side wall opening forms a drainage channel to accelerate the water discharge. The liquid level in the cylinder drops sharply, forming a local negative pressure zone. The sliding ring is forced downward to reset due to the difference between its own gravity and the external atmospheric pressure. The periodic influx and retreat of waves causes the fluid in the cylinder to form a pulsating "lift-drain" cycle. The resulting alternating lift and suction continuously act on the sliding ring sealing surface, converting it into a vertical reciprocating mechanical displacement synchronized with the wave frequency. This process does not require additional transmission components and directly utilizes the natural conversion of wave fluid potential energy to kinetic energy to achieve drive.
[0034] In this embodiment, when waves naturally flow into the cylinder, the sliding ring is driven to rise and fall periodically along the axis of the cylinder. The push rod moves synchronously with the sliding ring and transmits the linear displacement to the inner rod. When the inner rod slides inside the outer rod, it drives all the fan blades to deflect around their rotation axis through the linkage mechanism (such as the attack angle adjustment frame and the eccentrically hinged attack angle rod), thereby changing the airflow attack angle of the vertical axis fan blades in real time.
[0035] In the prior art, the design of a fixed angle of attack for vertical power generation devices is essentially a static compromise. Its main contradiction is that engineers can only choose a certain wind speed range (such as the rated wind speed) to optimize the angle of attack. However, in actual marine wind farms, wind speeds change rapidly. At low wind speeds, a fixed angle of attack that is too large will cause the lift curve to enter the stall region, resulting in a sharp drop in aerodynamic efficiency. At high wind speeds, a fixed angle of attack that is too small will prevent the airflow from fully adhering to the fan blades, resulting in a decrease in energy capture rate and an inability to further improve power generation efficiency. In this embodiment, a purely mechanical transmission mechanism is used to make the fan blade angle of attack continuously change with the rise and fall of waves. The natural coupling characteristics of wave motion and sea surface airflow pulsation make this adaptive adjustment process without the need for external energy input or electronic control, and directly achieve dynamic optimization of aerodynamic performance in harsh marine environments, realizing closed-loop operation of wind power efficiency enhancement and wave power generation, establishing a continuously optimized energy conversion paradigm in a non-steady-state marine environment, and ultimately achieving a leap in system-level power generation capacity.
[0036] It should be noted that although the dynamic change of the wave-driven fan angle of attack used in this embodiment cannot always maintain the optimal value of the theoretical angle of attack, it still greatly improves the power generation efficiency compared to the fixed angle of attack. Through wave-driven periodic adaptive adjustment, the two fatal defects of the fixed angle of attack, namely deep stall and flow separation, are systematically avoided, thereby achieving a leap in power generation efficiency in a real ocean wind farm. Specifically: when the wave-driven angle of attack oscillates continuously between 8° and 22° (typical period 2-8 seconds), the blades periodically reduce the angle of attack in the low wind speed stage (to avoid stall), maintain the optimal lift-to-drag ratio to capture weak wind energy; when strong winds hit, the angle of attack is periodically and actively increased, using the transient high lift effect of the dynamic stall vortex to enhance energy capture and delay the stall critical point; more importantly, the natural frequency of wave motion is highly coupled with the turbulent pulsation of the offshore wind field, so that the oscillation of the angle of attack is close to the rhythm of wind energy pulses. For example, in the critical window period of 1-2 seconds when the wind speed suddenly increases, the waves synchronously push the angle of attack to approach the optimal range, efficiently capturing high-density wind energy; while the fixed angle of attack can only exert a small part of its aerodynamic potential due to the stall effect at this time. This instantaneous angle of attack deviation cost is exchanged for a strategy of avoiding more than half of the efficiency collapse zone, and the synergistic effect of passively suppressing the aerodynamic load of the aerodynamic pulse increases the annual equivalent power generation.
[0037] As a preferred embodiment, Figure 6 and Figure 7As shown, the outer rod includes a bottom rod and a top rod rotatably connected to the bottom rod. A power generation disk is disposed between the bottom and top rods. The bottom of the bottom rod is fixedly mounted on the top of the cylinder, the top of the bottom rod is connected to the power generation disk, and the top of the top rod is fixedly connected to the base. It should be noted that the power generation disk is a prior art, and generating electricity through the rotation of the blades is well known to those skilled in the art. In this example, the torque generated by the rotation of the blades in response to wind is transmitted to the top rod via the base. The bottom end of the top rod is rigidly connected to the rotor of the power generation disk, driving the rotation of the permanent magnet rotor inside the power generation disk, ultimately achieving power output. The specific logic will not be repeated here.
[0038] As a preferred embodiment, the blades are distributed around the base and rotatably connected to the base. An angle-of-attack rod is eccentrically hinged on each blade. An angle-of-attack adjustment bracket is provided at the top of the base, connected to the top of the inner rod. The free ends of the angle-of-attack rods are connected to the bracket. In this embodiment, when the sliding ring within the wave drive cylinder is raised or lowered, the push rod drives the inner rod to slide up and down within the outer rod. The angle-of-attack adjustment bracket at the top of the inner rod is subsequently displaced, pulling the eccentrically hinged angle-of-attack rods on each blade into synchronous motion. The pulling action of the angle-of-attack rods forces all blades to rotate about their pivotal connection points with the base, thereby changing the direction of the blade airflow kinetic energy in real time.
[0039] As a preferred embodiment, Figure 2 As shown, a power generation device and several wave power generation components are provided on the wind power platform, and each wave power generation component is connected to the power generation device; Figure 4 and Figure 5 As shown, the power generation component includes a rotating component and a generator. The rotating component is connected to each wave power generation component, and the rotating component is connected to the generator to drive the generator to work.
[0040] Furthermore, if Figure 5 As shown, the rotating element comprises a fixed cylinder, a rotating shaft, and several worm gear fans mounted on the rotating shaft. A water inlet port is formed at one end of the fixed cylinder, and a water outlet port is formed at the other end. The rotating shaft is rotatably mounted within the fixed cylinder. One end of the rotating shaft extends beyond the fixed cylinder and is connected to an aeration impeller, while the other end of the rotating shaft is connected to a generator. In this embodiment, a portion of the aeration impeller extends into the aquaculture tank to provide aeration and oxygenation. The generator is an existing component used for power generation.
[0041] As a preferred embodiment, Figure 3As shown, the wave power generation component includes a suction cylinder fixedly arranged on the wind power platform, a suction chamber is formed in the suction cylinder, a piston column is sealed and slidably connected in the suction chamber, the top of the piston column is movably connected to the first rod body, the free end of the first rod body (that is, the top of the first rod body) is hinged to the second rod body, the bottom end of the second rod body is movably connected (hinged) to the floating body, and a third rod body is fixedly arranged on the wind power platform, and the top of the third rod body is hinged to the middle position of the second rod body; the suction chamber is connected to a water inlet pipe and a water outlet pipe, the water inlet pipe is provided with a first one-way valve, the water outlet pipe is provided with a second one-way valve, the water inlet pipe extends below the liquid surface, and the water outlet pipe is connected to the water inlet interface.
[0042] According to the above technical solution, the floating body produces periodic lifting and lowering displacements under the action of sea waves. This movement is converted into a reciprocating compression stroke of the piston column in the suction chamber through a lever transmission mechanism (composed of a first rod body, a second rod body, and a hinged fulcrum). When the piston column moves upward, a negative pressure zone is formed in the suction chamber. Under the action of the pressure difference, the seawater pushes open the first one-way valve, closes the second one-way valve, and is sucked into the suction chamber through the water inlet pipe. When the piston column moves downward, the piston column compresses the water in the suction chamber, causing the pressurized water flow to push open the second one-way valve and close the first one-way valve, and then be discharged at high speed through the outlet pipe. The high-speed water output by multiple wave power generation components converges through parallel pipelines to the water inlet interface of the fixed cylinder, forming concentrated impact kinetic energy in the narrow flow channel of the fixed cylinder, strongly driving the worm fan assembly to rotate. The coaxial rotating shaft of the worm fan achieves two functional couplings during this process: First, the end of the rotating shaft is directly connected to the generator rotor, converting the kinetic energy of the wave and water flow into electrical output; second, the opposite extension of the rotating shaft passes through the fixed cylinder seal structure to connect to the aeration impeller. As the aeration impeller rotates, it creates a strong vortex shear effect, efficiently drawing surface air into the deeper water, generating a dynamic water flow rich in dissolved oxygen, which is then ejected into the aquaculture tank through the water outlet. This mechanism cleverly utilizes a single drive shaft to simultaneously complete the two-stage energy conversion chain—converting captured wave energy into electricity while also providing support for ecological aquaculture, achieving a passive and coordinated operation of energy production and ecological conservation.
[0043] In this embodiment, the wave power generation assembly converts wave energy into water pressure energy through a float, a lever mechanism, and a piston system. The specific operating process is as follows: the float generates vertical displacement as the waves rise and fall, driving the second lever to form a lever motion with the hinge point of the third lever as the fulcrum. The second lever, in conjunction with the first lever, pulls the piston rod to perform a reciprocating stroke within the suction chamber. When the float falls with the wave trough, the piston rod moves upward, creating negative pressure in the suction chamber, and seawater is drawn in through the inlet pipe equipped with a first one-way valve. When the float rises, the lever acts in reverse, forcing the piston rod downward, pressurizing the water in the suction chamber and opening the second one-way valve. High-pressure water is continuously output through the outlet pipe to the fixed cylinder. The lever mechanism converts the periodic fluctuations of the waves into linear compression of the water by the piston rod. The two one-way valves work together to form a directional fluid path, ensuring that water can only be drawn in through the inlet pipe and forced out through the outlet pipe, thereby generating continuously pulsating water pressure energy that is transmitted to the generator.
[0044] As a preferred embodiment, Figure 1 and Figure 2 As shown, each float has an arc-shaped structure and is surrounded by the outer periphery of the wind turbine platform. When the float moves with the waves, the float can weaken the direct impact of turbulence on the wind turbine platform and the breeding box. At the same time, the continuous closed structure composed of the arc array enhances the uniformity of the overall buoyancy distribution of the platform, effectively dissipates energy through collective undulating motion under the coupling of wind and waves, and provides stability for the wind turbine platform.
[0045] Furthermore, each wave-entry opening corresponds to the gap between adjacent floats. The wave-entry openings opened on the side walls of each cylinder precisely correspond to the gaps formed between adjacent arc-shaped floats. When waves surge towards the platform, the gaps between the floats act as natural wave-gathering troughs to gather and direct the wave energy to the openings. The wave beams passing through the gaps are directly introduced into the cylinder cavity before they decay, effectively driving the sliding ring to rise. This design not only maintains the enhanced effect of the surrounding structure of the floats on the stability of the platform, but also prevents the group of floats from obstructing the wave incident path, ensuring that the cylinder can continuously receive high-intensity water flow input to drive the internal rod lifting and adjustment mechanism.
[0046] In another embodiment, Figure 9 、 Figure 10 and Figure 11 As shown, the gaps between adjacent floating bodies form a V-shaped wave-gathering channel, and deflectors are provided at both ends of each floating body. The deflectors extend to the wave inlet opening of the cylinder, forming a wave acceleration and deflection structure; a rotating shaft is rotatably arranged between two adjacent deflectors, and a linked water turbine is provided on the rotating shaft, and a circulating pump (not shown) is coaxially connected to the rotating shaft; the water outlet of the circulating pump is connected to a water distribution pipe, which extends to the bottom of the aquaculture tank.
[0047] In this embodiment, when waves surge towards the platform, the V-shaped gaps between adjacent arc-shaped floats form a natural wave-gathering channel. In this gap area, the rotating shaft arranged between adjacent guide plates is equipped with a linked turbine. The high-speed water flow drives the linked turbine to rotate and thus drives the rotating shaft to rotate; the rotating shaft is directly connected to the main shaft of the circulation pump through a rigid coupling, so that the water flow is converted into mechanical energy of the pump. The water outlet of the circulation pump is passed into the bottom of the aquaculture tank through a water distribution pipe, and the water flow is injected from the bottom of the aquaculture tank, which can form a vertical circulation from bottom to top. During the rising process of the water flow, micro-nano bubbles are continuously released to prolong the dissolved oxygen time, forcibly stirring the bottom sediment to avoid anoxic dead water areas; at the same time, the rising water flow carries the excrement to the surface sewage collection area, forming a water body self-purification ecological circulation system.
[0048] As a preferred embodiment, a support shaft is provided on the top of the wind power platform, and a horizontal axis wind turbine is provided on the top of the support shaft. The horizontal axis wind turbine is used for power generation. It is an existing technology. The horizontal axis wind turbine and the vertical axis wind turbine are combined together. The vertical axis wind turbine can absorb the remaining wind energy of the horizontal axis wind turbine, thereby improving the utilization rate of offshore wind energy, increasing the power generation of the combined offshore wind power system, and reducing the power generation cost per kilowatt. It is conducive to further accelerating the realization of offshore wind power evaluation and improving the coordination between energy production and ecological breeding of offshore wind power platforms.
[0049] In a possible implementation, the horizontal axis fan is connected to the circulation pump to achieve better oxygenation and water distribution effects.
[0050] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by those skilled in the art based on the present invention is within the protection scope of the present invention.
