The bamboo-joint floating tube structure is composed of multiple floating tube segments connected in series. A pendulum plate is rigidly connected to the bottom of each floating tube segment, and a power generation mechanism is set between the floating tube segments. The photovoltaic power generation unit includes a photovoltaic panel set above the area enclosed by the floating tube segments and a truss supporting the photovoltaic panel. The truss is connected to the power generation mechanism via a PTO. When the device is subjected to external waves, the waves first act on the bamboo-joint floating tube structure.

Description

Technical Field

[0001] This invention relates to the field of marine engineering, and in particular to a bamboo-shaped wave energy photovoltaic complementary power generation platform with wave-damping function. Background Technology

[0002] With the continued growth of global energy demand and increasing environmental awareness, the development of marine renewable energy is receiving increasing attention. Wave energy and solar energy are two of the most promising marine renewable energy sources, and they are naturally complementary in terms of time and space: wave energy is relatively weak during the day when there is ample sunlight, while it is often more abundant at night or during cloudy or rainy weather. Therefore, combining wave energy power generation with photovoltaic power generation to form a multi-energy complementary power generation platform can effectively improve the stability of energy output and the utilization rate of marine space.

[0003] Currently, offshore wave energy generation devices mainly include oscillating water column type, pendulum type, and oscillating float type. Among them, pendulum wave energy generation devices are widely studied due to their relatively simple structure and high conversion efficiency. Traditional pendulum wave energy generation devices typically hinge a pendulum plate to a fixed foundation or float, using waves to propel the pendulum plate to oscillate relative to the float, and converting the oscillating mechanical energy into electrical energy through a hydraulic system, mechanical transmission, or linear generator. However, such devices have many inherent drawbacks: the number of underwater moving parts is large, and the hinge structure between the pendulum plate and the float, as well as the transmission mechanism, are submerged in seawater for extended periods, facing problems such as sealing difficulties, corrosion and wear, and marine organism attachment, resulting in high maintenance costs and difficulty in ensuring system reliability; the energy transmission path is relatively long, as the oscillation of the pendulum plate needs to pass through intermediate links such as connecting rods, hydraulic systems, or gear racks to drive the generator, and each link has mechanical friction, hydraulic leakage, or energy conversion losses, limiting the overall conversion efficiency; in addition, the float of traditional pendulum devices is usually a monolithic structure, which moves with the waves with a large amplitude under wave action, easily causing fatigue damage to the connecting parts, and the float itself lacks wave damping function, failing to provide a stable working environment for itself.

[0004] In the field of offshore photovoltaic (PV) power generation, existing floating PV systems typically mount photovoltaic panels on an integral floating hull that floats on the water surface. However, the integral floating hull is susceptible to significant movement due to wave impacts in harsh sea conditions, leading to uneven stress on the PV panels, structural fatigue, and even damage. Furthermore, existing floating PV systems only have a single power generation function, failing to fully utilize the wave energy resources of the ocean. In recent years, solutions combining wave energy generation and PV power generation have emerged, but these are mostly simple functional additions, lacking synergistic structural design. The wave energy capture mechanism is separated from the floating hull, further increasing system complexity and underwater sealing difficulties. Some solutions use netting or buoys as wave-damping structures, but these flexible components are prone to fatigue and damage under long-term wave action, and their wave-damping effect is limited, failing to create a completely stable water area within the floating tube enclosure, thus affecting the stability and power generation efficiency of the PV panels. Therefore, this application proposes a solution to address these problems. Summary of the Invention

[0005] Purpose of the invention: The purpose of this invention is to provide a bamboo-joint type wave energy photovoltaic complementary power generation platform with wave-damping function, which aims to solve the problems of existing technologies such as many underwater moving parts, difficulty in sealing, large energy transfer loss, low structural integration, lack of wave-damping function, and unstable working environment of photovoltaic panels.

[0006] Technical solution: The present invention provides a bamboo-joint wave energy photovoltaic complementary power generation platform with wave-damping function, comprising a bamboo-joint floating tube structure and a photovoltaic power generation unit;

[0007] The bamboo-joint floating tube structure is composed of multiple floating tube segments connected in series. A swing plate is rigidly connected to the bottom of each floating tube segment, and universal joints are provided at both ends. The universal joints are connected to each other by a crankshaft, and the output end of the crankshaft is connected to a power generation mechanism.

[0008] The photovoltaic power generation unit includes a photovoltaic panel installed above the area enclosed by the floating tube segment and a truss supporting the photovoltaic panel. The truss includes a buoyancy bottom beam, a rectangular beam, and an umbrella-shaped buoyancy support frame. The rectangular beam is located below the photovoltaic panel and supports it. The buoyancy bottom beam is located below the rectangular beam and provides buoyancy. The umbrella-shaped buoyancy support frame is located at the bottom of the buoyancy bottom beam and consists of multiple radial rods that converge at the central origin of the buoyancy bottom beam. Any of the rods is connected to the power generation mechanism via a PTO (Power Transfer Tolerance).

[0009] When subjected to external waves, this device first acts on the bamboo-joint floating tube structure and the pendulum plate. Due to the wave-damping effect of the bamboo-joint segmented structure and the damping effect of the pendulum plate, the energy of the external waves is effectively reduced, resulting in a stable and wave-free water area enclosed by the floating tubes. At the same time, each floating tube segment drives the pendulum plate to move with the waves, and relative rotation occurs between adjacent segments. This rotation is driven by a universal joint to rotate the crankshaft, which in turn drives the piston to reciprocate, driving the generator to convert mechanical energy into electrical energy. Since there are no waves in the internal area, the photovoltaic power generation unit remains relatively stable, while the floating tube segments move with the waves. The relative motion between the two drives the PTO (Polymerized Toll Collection Unit) to generate electricity. The synergistic effect of multiple PTOs not only generates additional electrical energy but also maintains the spatial stability of the photovoltaic panels. The photovoltaic panels efficiently receive solar energy and convert it into electrical energy in a stable environment. The buoyancy bottom beam and the umbrella-shaped buoyancy support frame jointly ensure the floating stability of the photovoltaic panels, thereby realizing complementary power generation of wave energy and solar energy, as well as the wave-damping function of the platform itself.

[0010] Preferably, the bamboo-type floating tube structure, which is formed by connecting multiple floating tube segments in sequence, has the shape of a regular polygon structure. The regular polygon structure is one of a regular hexagon, a regular octagon, or a regular dodecagon structure. The horizontal included angle between adjacent floating tube segments is determined by the interior angle of the polygon, so that the entire bamboo-type floating tube structure is approximately circular in the horizontal plane.

[0011] When the entire bamboo-joint floating pipe structure is approximately circular in the horizontal plane, it exhibits excellent response characteristics to waves in any direction.

[0012] Preferably, the oscillating plate is a solid steel plate or a fiber-reinforced composite material plate, and the width of the oscillating plate matches the length of the corresponding floating pipe segment. The oscillating plate is rigidly fixed to the bottom surface of the floating pipe segment by vertical welding, integral molding or high-strength bolt connection. The surface of the oscillating plate is a solid structure without holes to maintain the maximum wave thrust receiving area and maximize the wave energy capture efficiency.

[0013] Preferably, the photovoltaic panel is symmetrically tilted in a ridge shape, with the tilt angle adapted to the dimension of the installation area and the lighting conditions.

[0014] Preferably, the power generation mechanism includes a piston, a connecting rod, piston rings, a retaining ring, and a generator. One end of the connecting rod is connected to the crankshaft, and the other end is connected to the piston. The piston rings and retaining rings are disposed on the piston. The piston is coupled to the generator and performs piston movement within the generator.

[0015] The connecting rod connects to the crankshaft and inputs power to the piston for reciprocating motion. The piston rings and retaining rings are used for sealing and preventing lubricating oil leakage.

[0016] Preferably, it also includes a sealed housing that encloses the generator mechanism and crankshaft, and the sealed housing is sealed to the floating pipe sections on both sides by sealing rings and flanges.

[0017] The sealed casing prevents seawater from seeping in and extends the overall service life of the power generation unit.

[0018] Preferably, the universal joint is a cross-type universal joint or a ball cage type universal joint, and the two ends of the universal joint are connected to the floating pipe section and the crankshaft respectively by flange or welding.

[0019] The universal joint allows adjacent floating pipe segments to undergo relative pitch and horizontal swaying motions under the action of waves, and transmits the relative rotational motion between adjacent floating pipe segments, mainly the pitch component, while not restricting the free swaying of each floating pipe segment and its swing plate with the waves.

[0020] Preferably, the floating pipe segment is provided with anti-sinking material, which is closed-cell foam plastic or lightweight concrete. The density of the anti-sinking material is less than that of seawater, and it fills the entire internal cavity of the floating pipe segment by injection molding, grouting or filling.

[0021] Preferably, the rectangular beam is rectangular in shape and consists of multiple rectangular grids. Each rectangular grid contains a diagonal beam, and the diagonal beams in adjacent rectangular grids are connected end to end to form a continuous triangular truss system. A buoyancy bottom beam is connected to the bottom chord of the rectangular beam. The buoyancy bottom beam is coaxial with the bottom chord of the rectangular beam and has a diameter larger than the bottom chord. The members in the umbrella-shaped buoyancy support frame converge at the central origin and are distributed radially in an umbrella-like shape.

[0022] The rectangular beams form a continuous triangular truss system, which can ensure structural stiffness and reduce weight. The buoyancy bottom beam is used to provide buoyancy, and the radial members are used to further stabilize the photovoltaic panels and share the buoyancy.

[0023] Preferably, the number of rods in the power generation mechanism, PTO, and umbrella-shaped buoyancy support frame corresponds one-to-one, with one end of the PTO connected to the power generation mechanism and the other end connected to the rod.

[0024] Multiple PTOs work together to not only generate additional electrical energy, but also work together to maintain the spatial balance and stability of the photovoltaic panels, without the need for an additional active control system.

[0025] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages:

[0026] 1. This invention rigidly connects the pendulum plate to the floating pipe segment. By utilizing the relative rotation of adjacent floating pipe segments under the action of waves, the generator is directly driven to generate electricity through the universal joint-crankshaft-piston mechanism. This eliminates the underwater moving parts such as hinges, connecting rods, and hydraulic systems that are indispensable in traditional pendulum wave energy devices, greatly reducing the risks of seawater corrosion, sealing failure, and biological attachment, and significantly improving the reliability and service life of the wave energy power generation device.

[0027] 2. In this invention, the energy transfer path of wave energy is extremely short. The relative rotation of adjacent floating pipe sections is directly transmitted to the crankshaft through the universal joint. The crankshaft drives the piston to reciprocate. The piston is directly coupled to the generator. There is no need to go through intermediate transmission links such as hydraulic oil circuit or gear rack, which effectively reduces mechanical friction and energy dissipation, thereby improving the overall conversion efficiency of wave energy to electrical energy.

[0028] 3. The present invention adopts a bamboo-joint segmented floating tube structure in combination with the damping effect of the rigid pendulum plate below, so that the platform itself has good wave compliance and wave dissipation ability, which can effectively reduce external wave energy and make the internal area enclosed by the floating tube form a stable and wave-free water area, providing a stable working environment for the photovoltaic power generation unit without wave disturbance, and avoiding the decrease in power generation efficiency and structural fatigue caused by the shaking of the photovoltaic panel.

[0029] 4. In this invention, a PTO extends from each sealed shell, with one end connected to the sealed shell and the other end connected to the umbrella-shaped support frame. When the floating tube segment moves with the waves while the internal photovoltaic panel remains stable, the relative motion between the two drives the PTO to generate electricity, realizing multi-level capture and utilization of wave energy. Multiple PTOs work together to not only generate additional electrical energy, but also collaboratively maintain the spatial balance and stability of the photovoltaic panel, without the need for an additional active control system.

[0030] 5. The photovoltaic panel in this invention adopts a herringbone-shaped roof-like arrangement, with a rectangular beam, a buoyancy bottom beam, and an umbrella-shaped buoyancy support frame below. The buoyancy bottom beam is coaxial with the lower chord of the rectangular beam and has a larger diameter, providing additional buoyancy. The umbrella-shaped radiating rods converge at the central origin, effectively enhancing the photovoltaic panel's anti-overturning ability and floating stability, and maintaining the photovoltaic panel's optimal light-receiving posture even under wave disturbance.

[0031] 6. The present invention fills each floating pipe segment with low-density anti-sinking materials such as closed-cell foam plastic or lightweight concrete. Even if the outer shell of the floating pipe segment is accidentally damaged due to collision or fatigue, the anti-sinking material can still provide sufficient positive buoyancy to prevent the platform from sinking, thus ensuring the platform's survivability and asset safety in harsh sea conditions and having high safety redundancy.

[0032] 7. The multiple floating pipe segments of this invention can be flexibly assembled into various regular polygonal structures according to sea conditions; the height of the truss-type photovoltaic panel support structure is adjustable, which is convenient to adapt to the optimal tilt angle at different latitudes, further enhancing the platform's environmental adaptability and modular deployment capability.

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0039] See appendix Figures 1-5 Figure shows the bamboo-shaped wave energy photovoltaic complementary power generation platform with wave-damping function in this invention, which includes a bamboo-shaped floating tube structure and a photovoltaic power generation unit. The bamboo-shaped floating tube structure is composed of multiple floating tube segments 1 connected in series. A swing plate 2 is rigidly connected to the bottom of the floating tube segment 1, and universal joints 3 are respectively provided at both ends. The universal joints 3 are connected to each other through a crankshaft 4, and the output end of the crankshaft 4 is connected to a power generation mechanism.

[0040] The power generation mechanism includes a piston 10, a connecting rod 11, piston rings 12, retaining rings 13, and a generator 14. One end of the connecting rod 11 is connected to the crankshaft 4, and the other end is connected to the piston 10. The piston rings 12 and retaining rings 11 are mounted on the piston 10. The piston 10 is coupled to the generator 14 and performs piston movement within the generator 14. After the connecting rod 11 is connected to the crankshaft 4, it inputs the power for reciprocating motion up and down to the piston 10. The piston rings 12 and retaining rings 13 are used for sealing and preventing lubricating oil leakage.

[0041] The photovoltaic power generation unit includes a photovoltaic panel 5 installed above the enclosed area of ​​the floating tube section 1 and a truss supporting the photovoltaic panel 5. The truss includes a buoyancy bottom beam 6, a rectangular beam 7, and an umbrella-shaped buoyancy support frame 8. The rectangular beam 7 is located below the photovoltaic panel 5 to support the photovoltaic panel 5. The buoyancy bottom beam 6 is located below the rectangular beam 7 to provide buoyancy. The umbrella-shaped buoyancy support frame 8 is located at the bottom of the buoyancy bottom beam 6 and is composed of multiple radial rods that converge at the central origin of the buoyancy bottom beam. Any rod is connected to the power generation mechanism through PTO9.

[0042] In this embodiment, the bamboo-type floating tube structure, which is formed by connecting multiple floating tube segments 1 in series, is a regular polygon structure. The regular polygon structure is one of a regular hexagon, a regular octagon, or a regular dodecagon. The horizontal angle between adjacent floating tube segments 1 is determined by the interior angle of the polygon, so that the entire bamboo-type floating tube structure is approximately circular in the horizontal plane.

[0043] When the entire bamboo-joint floating pipe structure is approximately circular in the horizontal plane, it exhibits excellent response characteristics to waves in any direction.

[0044] In this embodiment, the pendulum plate 2 is a solid steel plate or a fiber-reinforced composite material plate. The width of the pendulum plate 2 matches the length of the corresponding floating pipe segment 1. The bottom surface of the pendulum plate 2 and the floating pipe segment 1 are rigidly fixed by vertical welding, integral molding or high-strength bolt connection. The surface of the pendulum plate 2 is a solid structure without holes to maintain the maximum wave thrust receiving area and maximize the wave energy capture efficiency.

[0045] In this embodiment, the photovoltaic panel 5 is symmetrically tilted in a ridge shape, and the tilt angle is adapted to the dimension of the installation area and the lighting conditions.

[0046] In this embodiment, a sealing shell 15 is also included. The sealing shell 15 encloses the power generation mechanism and the crankshaft 4. The sealing shell 15 is sealed to the floating pipe sections 1 on both sides through sealing rings and flanges to prevent seawater from seeping in and improve the overall service life of the power generation mechanism.

[0047] In this embodiment, the universal joint 3 is a cross-type universal joint or a ball cage type universal joint. The two ends of the universal joint 3 are connected to the floating pipe segment 1 and the crankshaft 4 respectively by flange or welding. The universal joint 3 enables the relative pitching and horizontal swaying motion between adjacent floating pipe segments 1 under the action of waves, and transmits the relative rotational motion between adjacent floating pipe segments 1, mainly the pitching motion component, while not restricting the free swaying of each floating pipe segment 1 and its swing plate 2 with the waves.

[0048] In this embodiment, the floating pipe segment 1 is provided with anti-sinking material, which is closed-cell foam plastic or lightweight concrete. The density of the anti-sinking material is less than that of seawater. It fills the entire internal cavity of the floating pipe segment 1 by injection molding, grouting or filling. When the outer shell of the floating pipe segment 1 is accidentally damaged, the anti-sinking material 8 can prevent seawater from entering and provide additional positive buoyancy to prevent the platform from sinking.

[0049] In this embodiment, the rectangular beam 7 is rectangular in shape and is composed of multiple rectangular grids inside. A diagonal beam is provided in any rectangular grid. The diagonal beams in adjacent rectangular grids are connected end to end to form a continuous triangular truss system. The triangular truss system can ensure structural rigidity and reduce weight.

[0050] A buoyancy bottom beam 6 is connected to the bottom chord of the rectangular beam 7. The buoyancy bottom beam 6 is coaxial with the bottom chord of the rectangular beam 7 and has a larger diameter than the bottom chord. The buoyancy bottom beam 6 is used to provide buoyancy.

[0051] The rods in the umbrella-shaped buoyancy support frame 8 converge at the central origin and are distributed radially in an umbrella-like shape. The radial rods are used to further stabilize the photovoltaic panel and share the buoyancy.

[0052] In this embodiment, the number of rods in the power generation mechanism, PTO9, and umbrella-shaped buoyancy support frame 8 corresponds one-to-one. One end of PTO9 is connected to the power generation mechanism, and the other end is connected to the rod. Multiple PTOs work together to not only generate additional electrical energy, but also work together to maintain the spatial balance and stability of the photovoltaic panel without the need for an additional active control system.

[0053] The working process of this invention is as follows: The platform floats on the water surface. External waves first act on the bamboo-joint floating tube structure and the pendulum plate 2, effectively reducing wave energy and creating a stable, wave-free water area within the enclosure of the floating tube segments 1. Simultaneously, the pendulum plate 2 drives each floating tube segment 1 to move with the waves, resulting in relative rotation between adjacent segments. This rotation is driven by the universal joint 3, which in turn drives the crankshaft 4 to rotate. The crankshaft 4, through the connecting rod 11, drives the piston to reciprocate, thus converting mechanical energy into electrical energy. Because the internal area is wave-free, the photovoltaic panel 5 remains relatively stable, while the floating tube segments 1 move with the waves. This relative motion drives the PTO9 extending from each sealed outer shell to generate electricity. Multiple PTO9s work together, generating additional electrical energy while maintaining the spatial stability of the photovoltaic panel 5. The herringbone-shaped photovoltaic panel 5 efficiently receives solar energy and converts it into electrical energy in a stable environment. The buoyancy bottom beam 6 and the umbrella-shaped buoyancy support frame 8 jointly ensure the floating stability of the photovoltaic panel 5. This achieves complementary power generation from wave energy and solar energy, as well as the platform's own wave-damping function.
