Description

Technical Field

[0001] This invention relates to the field of new energy equipment and marine aquaculture engineering technology, and in particular to a wind and wave resistant snorkeling solar-aquaculture hybrid platform. Background Technology

[0002] With the rapid development of the marine economy, the development of offshore renewable energy and the deep-sea aquaculture industry are facing unprecedented opportunities and challenges. As an innovative model integrating photovoltaic power generation and aquaculture, the economic viability and safety under extreme sea conditions of the solar-fishery hybrid platform have become key factors restricting the industry's development. Existing floating platforms often need to suspend operations and adopt passive defensive measures during extreme sea conditions such as typhoons, which not only affects economic benefits but also poses significant safety hazards.

[0003] Based on the distance between the photovoltaic modules and the sea surface, floating photovoltaic platforms can be broadly categorized into two technical approaches: high freeboard and low freeboard. The typical high freeboard approach uses a semi-submersible design, achieving excellent wave resistance through a high freeboard and low center of gravity, making it suitable for extreme sea conditions. However, it suffers from technical drawbacks such as complex structure, high weight, and high maintenance costs. Furthermore, its layout and system integration require specialized optimization when integrated with aquaculture cages. The typical low freeboard approach uses a pontoon-type design, offering advantages such as simple structure, low cost, and low wind load. However, it has weaker wave resistance, and the photovoltaic panels are more susceptible to wave impact.

[0004] Existing technology also discloses a floating truss platform, which consists of horizontally arranged pontoons at the bottom and a truss structure at the top. The raised truss platform achieves a higher freeboard, reducing the impact of waves on the photovoltaic panels. The horizontal pontoon design results in a low center of gravity and good stability. Simultaneously, the damping pool formed between the pontoons dissipates wave energy through damping and provides space for cage placement, facilitating the implementation of a fish-solar hybrid model. However, this type of platform has a large waterline area, making it prone to significant motion responses under wave loads. Especially in extreme sea states, its survivability faces severe challenges, posing safety hazards.

[0005] In addition, several liftable photovoltaic platform solutions have been disclosed in the existing technology, including: adjusting the length of the mooring cable by using an external winch, and controlling the mass of ballast water inside the floating body by using electric pumping equipment, so that the platform can sink below the sea surface under extreme sea conditions, thereby reducing the impact of environmental loads such as wind, waves and currents. However, such technical solutions have technical drawbacks such as complex system structure, high implementation cost and insufficient reliability.

[0006] In summary, a comprehensive analysis of existing offshore floating photovoltaic platform technologies reveals significant challenges in cost control and wave resistance, failing to provide a comprehensive solution that combines economy, high wave resistance, and high reliability. While semi-submersible platforms offer excellent wave resistance, their complex structural design leads to high costs and poor compatibility with aquaculture cages. Floating truss platforms, despite cost advantages and good cage compatibility, lack sufficient safety in extreme sea conditions. While using electric devices to adjust mooring cable length or ballast water mass can address safety issues in extreme sea conditions, these methods are costly and their reliability needs improvement.

[0007] Therefore, existing technologies still need improvement. Summary of the Invention

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] This application discloses a wind and wave resistant snorkeling solar-aquaculture hybrid platform, such as... Figure 1 and Figure 2 As shown, the system includes a pontoon 1, a photovoltaic panel, an aquaculture cage 4, and a counterweight assembly. The pontoon 1 encloses a damping pool 13, which contains seawater to suppress the movement of the pontoon 1. The photovoltaic panel is located on the top of the pontoon 1. The aquaculture cage 4 is connected to the bottom of the pontoon 1. The counterweight assembly is connected to the pontoon 1 to constrain its stability. The counterweight assembly includes a float 3. The float 3 is hollow and forms a receiving cavity and a sealed chamber 312. The receiving cavity is used to hold liquid, and the sealed chamber 312 is used to hold gas. The float 3 is equipped with a control valve group, which is used to adjust the connection between the receiving cavity and the external seawater, as well as the connection between the sealed chamber 312 and the receiving cavity.

[0025] This embodiment of the wind and wave resistant floating solar-aquaculture hybrid platform includes a buoy 1, a photovoltaic panel, an aquaculture cage 4, and a counterweight assembly. The buoy 1 floats on the sea surface. The photovoltaic panel is fixedly installed on the top plane of the buoy 1 by a bracket, with its sun-receiving surface facing the sky. At least a portion of its structure remains above the sea surface while floating to receive solar radiation and generate electricity. The top of the aquaculture cage 4 is fixedly connected to the bottom of the buoy 1. The counterweight assembly is connected to the buoy 1 and provides additional gravity when the platform is submerged to constrain the stability of the buoy 1's movement. Specifically, the counterweight assembly includes a float 3, which is hollow inside, forming two isolated chambers: a receiving cavity and a sealed chamber 312. The receiving cavity is used to hold a liquid medium, i.e., seawater; the sealed chamber 312 is used to hold a compressed gas medium, such as compressed air. A control valve assembly is provided on the outer shell of the float 3 to control the connection and disconnection between the receiving cavity and the external seawater, and to control the connection and disconnection between the sealed chamber 312 and the receiving cavity.

[0026] Under normal sea conditions, when wind speed, wave height, and period are all within the platform's design operating parameters, the containment chamber is filled with air, and the sealed compartment 312 stores high-pressure compressed air. The overall density of the float 3 is less than that of seawater, generating positive buoyancy, and the float 3 floats near the sea surface. The pontoon 1, connected to the float 3, also floats on the sea surface, with its bottom submerged and its top and photovoltaic panels completely above the water. The aquaculture cage 4 is completely submerged, and aquaculture activities are carried out inside. At this time, the damping tank 13 is always kept filled with seawater to provide motion damping for the platform.

[0027] like Figure 4 As shown, when encountering extreme sea conditions such as typhoons or giant waves, operators adjust the control valve assembly to connect the containment chamber with the external seawater. Under external water pressure, seawater enters the containment chamber, expelling the air inside through a pre-set exhaust channel. As seawater continues to be injected, the total weight of float 3 increases, the positive buoyancy gradually decreases and eventually turns into negative buoyancy, and float 3 begins to sink. The sinking motion of float 3 drives float 1 to submerge to a predetermined depth below the sea surface.

[0028] Once buoy 1 is completely submerged, the platform's waterline area decreases significantly. This substantial reduction in waterline area directly reduces the area affected by waves, effectively suppressing heave, roll, and pitch motions caused by wind and wave loads. Simultaneously, the submerged buoy 3's internal cavity fills with seawater, its own mass forming a concentrated counterweight, further maintaining the platform's stability.

[0029] Once the extreme sea conditions have passed and the sea conditions have returned to normal, the operators adjust the control valve assembly to cut off the connection between the containment chamber and the external seawater, allowing the high-pressure compressed air stored in the sealed compartment 312 to enter the top of the containment chamber. Because the pressure of the compressed air is greater than the hydrostatic pressure of the seawater at the bottom of the containment chamber, the compressed air forces the seawater in the containment chamber to be discharged into the external ocean. As the seawater is gradually discharged, the weight of the float 3 decreases, buoyancy is restored, and the float 3 pulls the float 1 to rise to the sea surface, and the platform returns to a floating state.

[0030] In one embodiment, the top of the pontoon 1 is provided with a truss structure 2. The truss structure 2 is formed by connecting steel sections or steel pipes through nodes to form a spatial grid skeleton, which has the characteristics of being lightweight and high-strength. Photovoltaic panels are installed on the truss structure 2 to maintain a predetermined distance between the photovoltaic panels and the sea surface, thereby avoiding wave impact while balancing photovoltaic power generation efficiency and structural rigidity. This embodiment of the application, by combining photovoltaic power generation, aquaculture, and active snorkeling technology, and using a damping pool 13 to suppress platform movement, significantly improves the environmental adaptability and operational safety of the offshore floating photovoltaic platform.

[0031] In this embodiment, as Figure 5As shown, the pontoon 1 is hollow, forming several compartments 11; these compartments 11 are used to house electrical equipment. The pontoon 1 is an annular pontoon; the float 3 is a spherical float 3. In actual production, the pontoon 1 has a hollow internal structure, forming several independent compartments 11. The compartments 11 can be used to install electrical drive components such as inverters, distribution boxes, and energy storage batteries. The annular pontoons enclose an open water area, which is defined as a damping pool 13. The damping pool 13 contains seawater. When the platform is subjected to wind and waves and undergoes heaving or rolling motion, the damping effect of the seawater (i.e., the seawater in the damping pool 13 generates a damping force opposite to the direction of platform movement due to inertia) is used to dissipate energy, thereby suppressing the pitching and rolling amplitude of the pontoon 1.

[0032] In this embodiment, the annular shape can enhance the symmetry of the pontoon 1 in terms of hydrodynamic performance, so that when the platform is subjected to waves and currents from different directions, the wave load and hydrodynamic force it experiences exhibits isotropic or nearly isotropic distribution characteristics, thereby significantly improving the platform's adaptability to changing wind and wave directions and reducing local load concentration and motion response deviation caused by directional differences.

[0033] In one implementation, such as Figure 3 and Figure 4 As shown, the counterweight assembly further includes a weight block 34, which is connected to the float 3; the weight block 34 is used to restrain the movement of the float 3. The float 3 is provided with a first mounting hole 315 and a second mounting hole 313; the first mounting hole 315 and the second mounting hole 313 are arranged circumferentially at intervals along the edge of the float 3; the wind and wave resistant floating-submersible solar-fishery complementary platform further includes a first mooring cable 32 and a second mooring cable 33; one end of the first mooring cable 32 is connected to the buoy 1, and the other end is connected to the first mounting hole 315; one end of the second mooring cable 33 is connected to the second mounting hole 313, and the other end is connected to the weight block 34.

[0034] Specifically, a first mounting hole 315 and a second mounting hole 313 are provided on the outer surface of the float 3. The first mounting hole 315 and the second mounting hole 313 are arranged at intervals along the circumferential edge of the float 3, and the central angle between them can be determined as 90 degrees, 120 degrees or 180 degrees according to the mooring force analysis, so that the mooring cable connected to the first mounting hole 315 and the second mounting hole 313 can form an open force angle in the horizontal plane, thereby providing bidirectional or all-directional horizontal restraint for the buoy 1 and the float 3.

[0035] In use, one end of the first mooring cable 32 is connected to the pre-set mooring point on the float 1, and the other end is connected to the first mounting hole 315 on the float 3. Similarly, one end of the second mooring cable 33 is connected to the second mounting hole 313 on the float 3, and the other end is connected to the pre-set mooring point on the weight block 34. The first mooring cable 32 can be made of fiber rope or composite rope to utilize its lightweight and flexible properties to accommodate the relative movement between the float 1 and the float 3; the second mooring cable 33 can be made of catenary steel cable or a combination of anchor chain and elastic buffer to provide sufficient tensile strength and impact absorption capacity. The weight block 34 is suspended below the float 3 by the second mooring cable 33. In the normal floating state of the platform, the weight block 34 helps to suppress the low-frequency drift motion of the entire platform. During the platform's descent, the weight block 34 maintains a downward pulling force on the float 3 to prevent excessive lateral displacement of the float 3 due to ocean currents.

[0036] In this embodiment, when encountering extreme sea conditions such as typhoons, after the buoy 3 and pontoon 1 complete their submersion, the control valve group on the buoy 3 switches to the closed state. After submersion, the buoy 3's internal cavity fills with seawater, significantly increasing its mass and thus forming a counterweight. The buoy 3, acting as a counterweight, is flexibly connected to the pontoon 1 via fiber ropes and anchored to the heavy block 34 on the seabed via catenary cables. Under the continuous action of the buoy 3's own weight, both the fiber ropes and the catenary cables are re-tensioned, thereby restoring and maintaining the overall restraint capability of the mooring system on the platform. This ensures the platform's horizontal positioning safety during submersion, effectively avoiding the technical problem of weakening mooring stiffness due to the loosening of the catenary cable's geometry during submersion, and guaranteeing the reliability of the mooring system under extreme sea conditions.

[0037] In this embodiment, the control valve assembly includes a first valve 311, a second valve 314, and a third valve. The first valve 311 is located at the top of the float 3; the second valve 314 is located at the end of the float 3 connected to the weight block 34. The control valve assembly can remotely receive control signals to open and close the first valve 311 and the second valve 314. Specifically, the first control valve is located at the top of the float 3, the second control valve is located at the bottom of the float 3, and both the first valve 311 and the second valve 314 are located on the fluid channel between the containment chamber and the external seawater (the number of fluid channels matches the number of valves), used to control the connection and disconnection between the containment chamber and the external seawater. The third control valve is installed on the gas channel between the sealed chamber 312 and the containment chamber, used to control the connection and disconnection between the sealed chamber 312 and the containment chamber.

[0038] When encountering extreme sea conditions such as typhoons or giant waves, operators issue commands through the surface control center. These commands are transmitted via underwater acoustic communication to the control valve assembly on float 3. Responding to the commands, the control valve assembly opens the first control valve and the second valve 314, connecting the containment chamber to the external seawater. Under external water pressure, seawater enters the containment chamber through the first control valve and the second valve 314, expelling air from the chamber through a pre-set exhaust channel. As seawater continues to flow in, the total weight of float 3 increases, the positive buoyancy gradually decreases and eventually turns into negative buoyancy, causing float 3 to begin to sink.

[0039] After the extreme sea conditions subsided and returned to normal, the operator issued another command. The control valve assembly responded by first closing the first valve 311 to cut off the connection between the top of the containment chamber and the external seawater. Then, it opened the third valve. At this point, the high-pressure compressed air stored in the sealed chamber 312 entered the containment chamber through the third valve and flowed to the top of the chamber. Because the pressure of the compressed air was greater than the pressure of the seawater at the bottom of the containment chamber, the compressed air forced the seawater in the containment chamber to flow backward through the second control valve to the external ocean. As the seawater was gradually discharged, the weight of the float 3 decreased, buoyancy was restored, and the float 3 carried the float 1 to the surface, and the platform returned to a floating state. After the ascent was complete, the control valve assembly closed the second valve 314 and the third valve, and manually replenished the sealed chamber 312 with compressed air for the next dive.

[0040] In this embodiment, when encountering extreme sea conditions such as typhoons or giant waves, the first valve 311 and the second valve 314 of the float 3 open simultaneously, allowing external seawater to enter the receiving cavity of the float 3 through the first valve 311 and the second valve 314 until the receiving cavity is completely filled with seawater. During the seawater injection process, due to factors such as local water pressure differences at the locations of the various floats 3, slight deviations in the opening sequence of the first valve 311 and the second valve 314, or ocean current disturbances, the seawater injection rate and instantaneous water volume in the receiving cavities of different floats may vary to some extent. This difference will lead to an imbalance in the downward pull generated by each float 3, which will then have a temporary adverse effect on the instantaneous balance state of the buoy 1, causing the buoy 1 to tilt or roll slightly. However, this water volume difference only exists in the dynamic process of seawater injection, and this process is short-lived, typically on the order of several seconds to tens of seconds. Once the cavities of all floats 3 are completely filled with seawater, the total weight of all floats 3 tends to be uniform, and the unbalanced pulling force caused by the initial water volume difference is eliminated. Float 1 then automatically returns to a balanced posture due to its own stability. Therefore, this temporary imbalance will not have a substantial impact on the platform's final diving state or subsequent operational safety.

[0041] In one specific embodiment, the second valve 314 is positioned on the float 3 near the second mounting hole 313. During actual use, the second mounting hole 313 is connected to the weight block 34 via the second mooring cable 33. Because the gravity of the weight block 34 is continuously transmitted to the float 3 through the second mooring cable 33, the second mounting hole 313 and its adjacent area are always subjected to a downward pull, ensuring that the local area where the second mounting hole 313 is located remains at the lowest liquid level in the entire snorkeling chamber throughout the entire snorkeling cycle. Therefore, positioning the second valve 314 near the second mounting hole 313 ensures that the second valve 314 remains at the lowest point in the snorkeling chamber during drainage. Simultaneously, because the weight block 34 exerts a continuous downward pull on the float 3 through the second mooring cable 33, the area outside the second valve 314 is always a seawater environment, eliminating gas-liquid interface interference.

[0042] When compressed air is injected from the top of the containment chamber, the air pressure drives the seawater to flow to the bottom, and the seawater is continuously and directionally discharged through the second valve 314 located at the lowest point. Throughout the drainage process, the compressed air always accumulates at the top of the containment chamber, thereby avoiding the problem of compressed air overflowing before drainage, and significantly improving the reliability of the buoyancy operation.

[0043] In this embodiment, a miniature underwater acoustic communication device is installed on the float 3. This device includes an underwater acoustic transducer, an underwater acoustic modem, and an embedded controller. In floating mode, the platform can use Bluetooth or wireless radio frequency communication; in submerged mode, it automatically switches to underwater acoustic communication mode to receive control commands from the water surface and provide feedback on valve status information. This control process is prior art and will not be described in detail here.

[0044] In another embodiment of the present invention, such as Figure 6 As shown, the wave-resistant floating solar-aquaculture hybrid platform also includes at least one connecting frame 12; at least one connecting frame 12 spans the damping pool 13, and both ends of the connecting frame 12 are respectively connected to the opposite sides of the buoy 1. The aquaculture cage 4 includes: a main frame 42 and a net 41; the main frame 42 is connected to the buoy 1; the net 41 is arranged around the main frame 42; the net 41 encloses to form an aquaculture chamber.

[0045] Specifically, the connecting frame 12 spans the damping pool 13, and its two ends are respectively connected to the opposite sides of the float 1. The connecting frame 12 serves as a trapezoidal walkway for workers, and its surface can be provided with anti-slip textures or grating to ensure the safety of personnel during daily operation and maintenance and under extreme working conditions. The aquaculture cage 4 includes a main frame 42 and a net 41. The main frame 42 is connected to the float 1 and can adopt a rigid frame structure, such as a three-dimensional frame welded from steel pipes or shaped steel. The net 41 is encircled on the main frame 42, that is, the net 41 covers the bottom and circumferential sides of the main frame 42 and is fixed to the main frame 42 by binding, buckling, or tensioning ropes. The net 41 encloses and forms a closed aquaculture chamber, which is used to contain aquaculture organisms such as fish and shellfish. The mesh size of the net 41 is determined according to the specifications of the aquaculture species, which prevents the aquaculture organisms from escaping while allowing free exchange of seawater inside and outside the aquaculture chamber to ensure dissolved oxygen supply and diffusion of metabolic products.

[0046] In summary, this invention discloses a wind and wave resistant snorkeling solar-aquaculture hybrid platform, comprising buoys, photovoltaic panels, aquaculture cages, and a counterweight assembly; the buoys enclose a damping pool; the damping pool is used to contain seawater to suppress the movement of the buoys; the photovoltaic panels are disposed on the top of the buoys; the aquaculture cages are connected to the bottom of the buoys; the counterweight assembly is connected to the buoys to constrain the stability of the buoys; the counterweight assembly includes a float; the float is hollow, forming a receiving cavity and a sealed chamber; wherein, the receiving cavity is used to hold liquid; the sealed chamber is used to hold gas; the float is equipped with a control valve assembly; the control valve assembly is used to adjust the connection between the receiving cavity and the external seawater, and the connection between the sealed chamber and the receiving cavity. Under normal sea conditions, the pontoon floats on the surface, enabling coordinated operation of photovoltaic power generation and aquaculture. In extreme sea conditions, the control valve assembly injects ballast water into the containment chamber, causing the float to sink and pull the pontoon to submerge to a predetermined depth. This reduces the pontoon's waterline area, mitigating the impact of wind and wave loads. Simultaneously, the submerged float itself acts as a counterweight, enhancing platform stability. Once sea conditions return to normal, the control valve assembly releases gas from the sealed chamber. The gas enters the containment chamber and expels seawater, causing the float to rise and pull the pontoon to float as well, restoring the platform to a floating state. This invention effectively resists extreme sea conditions, enabling coordinated operation of photovoltaic power generation and aquaculture, and ensuring the platform's operational safety in harsh environments.
