Description

Technical Field

[0001] This invention relates to the technical field of ocean wave energy fishing platforms, and in particular to a two-point mooring wave energy fishing platform. Background Technology

[0002] In the existing marine platforms, although there are marine fishing platforms, they face the following limitations: energy: relying solely on diesel / grid, without combining clean utilization of marine energy (wave energy, solar energy); space: the aquaculture area is "planarized", and the vertical space is idle; mooring: single-point mooring has weak wind and wave resistance and poor platform stability; function: the "aquaculture+" collaborative development is lacking and has not formed comprehensive benefits, specifically manifested as (1) energy supply dilemma: existing marine fishing platforms rely on external power grid or diesel power generation, the power supply in the far sea area is unstable and the operating cost is high, and diesel power generation (1) Pollution of the marine environment; (2) Inefficient use of space: The aquaculture model is mainly based on a single-layer plane, which does not fully tap the potential of the vertical space of the ocean, and the aquaculture capacity is limited. Traditional net cages are fully permeable structures; (3) Poor mooring stability: Traditional single-point or multi-point dispersed mooring is prone to drifting and swaying under the action of complex waves and currents, threatening the safety of aquaculture and the life of equipment; (4) Insufficient functional integration: It only focuses on the aquaculture link and lacks the integrated coordination of energy production, personnel life, ship operation and other functions, resulting in low efficiency of marine development; (5) The usual platform combination is impermeable and has poor water exchange efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a wave energy fishing platform with two-point mooring. By using two-point mooring to enhance platform stability, and through the coordinated power supply of ocean energy and solar energy, as well as the expansion of three-dimensional aquaculture, it can break through the bottlenecks of traditional fishing grounds such as "energy dependence, space waste, and single function", and provide an integrated solution for marine fisheries and ocean energy development, thereby improving the working efficiency of marine fishery platforms.

[0004] To achieve the above objectives, the present invention provides a wave energy fishing platform with two-point mooring, comprising a boat-shaped platform. The two ends of the platform are connected to anchors on the seabed via mooring equipment. Each end of the platform is provided with a semi-circular enclosed compartment. A rectangular open area is set between the two semi-circular enclosed compartments. Several isolation walls are set inside the rectangular open area. The area divided by the isolation walls is set as an aquaculture area. An auxiliary area is set above the aquaculture area. Ballast water tanks are set outside the semi-circular enclosed compartments, inside the isolation walls, and at the bottom of the rectangular open area. Wave energy devices are set inside the rectangular open area.

[0005] Preferably, the two semi-circular enclosed compartments are respectively set as an equipment area and a living area. The equipment area collects data from the platform in real time to achieve remote or local control. The living area is equipped with a residential area and a dining area to enable short-term stay of personnel.

[0006] Preferably, the device area specifically includes:

[0007] A water quality monitoring device, comprising a dissolved oxygen sensor, a temperature, salinity, and depth sensor, and a pH and turbidity sensor, is used to monitor the physicochemical parameters of aquaculture water in real time and transmit the data to the platform control center.

[0008] The energy management device, including wave energy generator set, energy storage battery pack and energy conversion controller, realizes the collection, storage and distribution of wave energy, and provides stable power for various equipment and living areas on the platform;

[0009] The mooring status monitoring equipment includes an anchor chain tension sensor, an attitude sensor, and a GPS positioning module, which is used to monitor the forces on the mooring system and the platform position drift in real time, and issue early warning signals when abnormalities occur.

[0010] The remote communication and control unit uploads platform operation data to the shore-based monitoring center via satellite communication, 5G or radio frequency link, and receives remote control commands, supporting local or remote dual-mode control.

[0011] The living area includes:

[0012] The living area is equipped with beds, lockers and emergency lighting to meet the short-term stay needs of the staff on duty.

[0013] The dining area is equipped with cooking equipment, a drinking water purification system, and refrigeration storage facilities.

[0014] The safety system includes fire alarm devices, life jackets, emergency escape hatches, and first aid kits.

[0015] Preferably, the wave energy device uses a hydraulic device or mechanical transmission structure to drive the generator to rotate through the wave buoyancy effect, converting wave energy into electrical energy. The upper surface of the auxiliary area is provided with a photovoltaic panel, which converts solar energy into electrical energy. The photovoltaic panel and the wave energy device form a combined power generation structure.

[0016] Preferably, the wave energy device includes a kinetic energy recovery device, a transmission mechanism, and a generator set;

[0017] The kinetic energy recovery device is located at the edge or outside of the rectangular open area. When located at the edge of the rectangular open area, the kinetic energy recovery device is configured as a rotating plate structure, including a vertical rotating shaft and a rotating plate mounted on the vertical rotating shaft. The rotating plate is connected to the transmission structure. When located outside the rectangular open area, the kinetic energy recovery device includes several floats, which are configured as spheres or disks. The floats are connected to the transmission structure on the edge of the rectangular open area via a rocking rod.

[0018] The transmission mechanism adopts a hydraulic device or a mechanical transmission structure, as detailed below:

[0019] When a hydraulic device is used, the float drives the piston of the hydraulic cylinder to reciprocate through the connecting rod. The high-pressure oil output by the hydraulic cylinder drives the hydraulic motor to rotate, which in turn drives the generator to generate electricity.

[0020] When a mechanical transmission structure is adopted, the float converts the reciprocating motion into unidirectional rotational motion through a rocker arm, gear or ratchet mechanism, driving the generator to rotate and generate electricity;

[0021] The wave energy device is equipped with an energy regulation and storage unit, including a hydraulic accumulator or flywheel device, to smooth out energy fluctuations caused by uneven wave input and ensure stable power generation output.

[0023] The auxiliary area includes several lifting columns, on which a roof is erected. Several photovoltaic panels are installed on the roof. An electrical device, including a feeder and an energy storage device, is installed on the top of the semi-circular enclosed chamber. The feeder feeds food into the net cage. The energy storage device is connected to the photovoltaic panels and the transmission mechanism to store electrical energy. A crane is installed on the outer wall of the rectangular open area to lift the net cage.

[0024] Therefore, the present invention employs the above-described two-point mooring wave energy fishing platform, which has the following advantages:

[0025] (1) In this invention, the platform is subjected to balanced forces by two-point mooring, and the horizontal displacement is significantly reduced compared with single-point mooring, providing a stable environment for aquaculture and power generation. Moreover, the structural design is similar to a bridge fixed at both ends, which can significantly improve the platform's anti-swaying ability.

[0026] (2) In this invention, wave energy and solar energy are utilized to form complementary power generation at different times. Wave energy utilization: the wave energy floats on both sides of the platform move periodically with the waves and drive the generator through hydraulic device / mechanical transmission to convert wave kinetic energy into electrical energy. Photovoltaic energy utilization: photovoltaic panels are laid on the upper middle layer to convert solar energy into electrical energy during the day, which complements wave energy power generation (on cloudy days / when the waves are low, photovoltaic / wave energy can supply power separately or in combination). The electrical energy is stored in energy storage equipment or directly used to power aquaculture machinery, lighting in living areas, and operation of instruments and equipment.

[0027] (3) In this invention, the upper auxiliary area and the lower aquaculture area are set up to realize the utilization of three-dimensional space for aquaculture, thereby improving aquaculture efficiency, reducing disease rate through ecological layout, and increasing fish survival rate and production.

[0033] Example

[0034] like Figures 1-2As shown, this invention provides a wave energy fishing platform with two-point mooring, including a boat-shaped platform 1. The two ends of the outer side of the platform 1 are connected to anchors on the seabed via mooring equipment 2. In the specific mooring process, single-point mooring and two-point mooring can be adopted. Single-point mooring is suitable for platform movement and can avoid the impact of severe weather such as typhoons. Two-point mooring can fix the angle of the platform 1 to face the waves, which is suitable for wave energy power generation. Semi-circular enclosed compartments 3 are provided at both ends of the platform 1. The outer side of the semi-circular enclosed compartments 3 can be selectively set as a pointed structure. The end of the pointed structure is connected to the mooring equipment 2. The two semi-circular enclosed compartments 3 are respectively set as an equipment area and a living area. Data of the platform 1 is collected in real time in the equipment area to realize remote or local control. The living area is set with a residential area and a catering area to realize short-term stay of personnel.

[0035] The equipment area includes:

[0036] The water quality monitoring device includes a dissolved oxygen sensor, a temperature, salinity, and depth sensor, and a pH and turbidity sensor. It is used to monitor the physicochemical parameters of the aquaculture water in real time and transmit the data to the platform control center.

[0037] The energy management device, including wave energy generator set, energy storage battery pack and energy conversion controller, realizes the collection, storage and distribution of wave energy, and provides stable power for various equipment and living areas on the platform;

[0038] The mooring status monitoring equipment includes an anchor chain tension sensor, an attitude sensor, and a GPS positioning module, which is used to monitor the forces on the mooring system and the platform position drift in real time, and issue early warning signals when abnormalities occur.

[0039] The remote communication and control unit uploads platform operation data to the shore-based monitoring center via satellite communication, 5G, or radio frequency links, and receives remote control commands, supporting both local and remote dual-mode control.

[0040] The living area includes:

[0041] The living area is equipped with beds, lockers and emergency lighting to meet the short-term stay needs of the staff on duty.

[0042] The dining area is equipped with cooking equipment, a drinking water purification system, and refrigeration storage facilities.

[0043] The safety system includes fire alarm devices, life jackets, emergency escape hatches, and first aid kits.

[0044] In this embodiment, the equipment area and living area are set up in a common and existing manner, which will not be described in detail here;

[0045] The middle of the two semi-circular enclosed chambers 3 is set as a rectangular open area 4. The interior of the rectangular open area 4 is set with several isolation walls 9. The area divided by the isolation walls 9 is set as the breeding area. In this embodiment, there are two isolation walls 9 and four net cages 8. An auxiliary area is set above the breeding area.

[0046] Ballast water tanks 7 are installed on the outside of the two semi-circular enclosed compartments 3, inside the isolation wall, and at the bottom of the rectangular open area 4. The draft of the platform is adjusted by the three ballast water tanks 7. Wave energy device 5 is installed in the rectangular open area 4 to recover wave energy.

[0047] The wave energy device 5 uses a hydraulic device or mechanical transmission structure to drive the generator to rotate through the wave buoyancy effect, converting wave energy into electrical energy. The upper surface of the auxiliary area is equipped with photovoltaic panels, which convert solar energy into electrical energy. The photovoltaic panels and the wave energy device 5 form a combined power generation structure.

[0048] The wave energy device 5 includes a kinetic energy recovery device, a transmission mechanism, and a generator set; the wave energy device includes a kinetic energy recovery device, a transmission mechanism, and a generator set;

[0049] The kinetic energy recovery device is located at the edge or outside of the rectangular open area 4. When located at the edge of the rectangular open area 4, the kinetic energy recovery device is configured as a rotating plate structure, including a vertical rotating shaft 51 and a rotating plate 52 mounted on the vertical rotating shaft. The rotating plate 52 is connected to a transmission structure. When located outside the rectangular open area 4, the kinetic energy recovery device includes several floats 53, which are configured as spheres or disks 54. The floats are connected to the transmission structure on the edge of the rectangular open area via rocking rods 55. The transmission mechanism 56 is connected via cables 57 to transport the recovered electrical energy to the storage device. In this embodiment, both rotating plate and float recovery methods are used.

[0050] Transmission mechanism 56 includes a hydraulic device or a mechanical transmission structure:

[0051] When a hydraulic device is used, the kinetic energy recovery device drives the piston of the hydraulic cylinder to reciprocate through the connecting rod. The high-pressure oil output by the hydraulic cylinder drives the hydraulic motor to rotate, which in turn drives the generator to generate electricity.

[0052] When a mechanical transmission structure is adopted, the kinetic energy recovery device converts reciprocating motion into unidirectional rotational motion through a rocker arm, gear, or ratchet mechanism, which drives the generator to rotate and generate electricity.

[0053] The wave energy device 5 is equipped with an energy regulation and storage unit, including a hydraulic accumulator or flywheel device, to smooth out energy fluctuations caused by uneven wave input and ensure stable power generation output.

[0054] In this embodiment, the wave energy device 5 is implemented as follows:

[0055] The hydraulic system adopts an integrated structure combining an oscillating float and a hydraulic cylinder, comprising three parts: an energy harvesting module, a hydraulic transmission module, and a voltage stabilization and power generation module, as detailed below:

[0056] Energy harvesting module: Includes a float and a guiding mechanism. The float adopts a teardrop-shaped streamlined design and is connected to three guide rods arranged in an equilateral triangle via a fixed plate, making vertical reciprocating motion along the guide rods. A double-rod hydraulic cylinder is installed above the float, with its sleeve end fixed to the top of the guide rod by a triangular bracket. The lower end of the piston rod is rigidly connected to the float, ensuring that the buoyancy motion of the waves is efficiently transmitted to the hydraulic system.

[0057] The hydraulic transmission module consists of a hydraulic cylinder, a composite oil pipe assembly, and a control valve assembly. The oil pipe system includes a high-pressure oil circuit and a return oil circuit. The oil pipes sequentially connect the lower chamber of the hydraulic cylinder, the oil tank, and the hydraulic motor inlet. The oil pipes also connect the upper chamber of the hydraulic cylinder and the hydraulic motor outlet, achieving bidirectional oil circulation through a check valve assembly. The system incorporates a built-in energy storage and pressure stabilization device, using a bladder-type accumulator to store high-pressure oil. When the pressure reaches a set threshold, the hydraulic motor drive circuit is automatically activated.

[0058] Stabilized power generation module: The hydraulic motor output shaft is connected to the generator via a coupling. Equipped with a tide level monitoring and adaptive system, including a tide gauge and a screw jack, it can adjust the installation height of the hydraulic cylinder according to the real-time tide level to ensure stable energy harvesting efficiency. The entire hydraulic unit is fixed by a counterweight of a hollow submersible body, which can be filled with seawater to adjust the draft and enhance stability under extreme sea conditions.

[0059] For the mechanical transmission structure, a rocker arm combined with a gear speed-increasing integrated scheme is adopted to realize the conversion from wave reciprocating motion to unidirectional rotational motion, specifically including:

[0060] Energy harvesting assembly: Consists of a single rocker arm and a float. One end of the rocker arm is hinged to the circular float, and the other end is rigidly connected to the input shaft of the transmission box. The length of the rocker arm is optimized according to the designed wave height to ensure maximum float movement amplitude. A counterweight is installed at the bottom of the float to lower the center of gravity and reduce lateral swaying caused by wave impact.

[0061] Reversing transmission module: The transmission box contains a gear ring shaft system, an output shaft system, and a reversing shaft system. The output shaft system and the reversing shaft system are each equipped with a one-way clutch gear, which meshes with the internal gear ring to form a transmission. When the float rises, the left gear drives the output shaft to rotate counterclockwise via a ratchet mechanism, while the right gear idles. When the float descends, the right gear drives the output shaft to rotate clockwise, achieving unidirectional rotational output through a two-stage gear reversal.

[0062] Speed-increasing generator assembly: The output end of the transmission box is connected to the gearbox via a coupling. A planetary gear speed-increasing mechanism is used to increase the speed to the generator's rated speed. A flywheel energy storage device is installed between the gearbox and the generator to control the generator speed non-uniformity coefficient within the national standard allowable range. Key transmission components are protected by a sealed housing filled with lubricating oil to achieve both corrosion prevention and lubrication.

[0063] The common auxiliary structures of hydraulic and mechanical transmission structures include the following auxiliary devices:

[0064] Anchoring structure: A combination of counterweight and anchor cable is adopted. One end of the anchor cable is connected to the submersible body, and the other end is fixed to the seabed to ensure the stability of the device in sea state 5.

[0065] Corrosion-resistant design: All exposed parts are made of 316 stainless steel, anti-corrosion sealing gaskets are installed at hydraulic pipeline interfaces, and the mechanical transmission box is filled with inert gas to prevent oxidation.

[0066] Energy Management System: Together with the photovoltaic panels in the auxiliary area, it forms a joint power supply network. Voltage matching is achieved through a DC / DC converter, and excess energy is stored in battery banks or directly used to power aquaculture equipment in the fish farm.

[0067] The aquaculture area is equipped with several net cages 8, each net cage 8 has a hanging point at its four corners, and the isolation wall 9 has holes as water flow channels. In this embodiment, water flow channels are opened on the longitudinal isolation wall 9. The inside of the net cage is equipped with a vertical net, on which filter-feeding organisms are cultured. Each net cage is used to raise fish or shrimp. The outer net cage 8 is connected to the ocean to achieve water quality control of natural ocean water flow.

[0068] The auxiliary area includes several lifting columns 11, on which a roof 12 is mounted. Several photovoltaic panels 13 are installed on the roof 12. An electrical device 10 is installed on the top of the semi-circular enclosed chamber 3, including a feeder and an energy storage device. The feeder feeds food into the net cage. The energy storage device is connected to the photovoltaic panels 13 and the transmission mechanism through cables to store electrical energy. A crane 6 is installed on the outer wall of the rectangular open area to lift the net cage 8.

[0069] For cranes, one specific implementation method is as follows:

[0070] Cranes: A-type gantry crane or side guide boom / small gantry crane combined with deck winch.

[0071] Force-bearing link: winch → guide pulley (top of type A gate) → steel wire cable / high-strength fiber cable → hook / quick release device → cage lifting frame / lifting point (can be equipped with short pry bar or simple lifting beam).

[0072] Rated capacity: Calculated based on a fully loaded net cage, including catch + water weight, and taking into account dynamic load factor, sea state gain and safety factor for selection;

[0073] Guiding and anti-swaying during the lifting process: Install guide rollers or guide rails: Arrange them at the fish jacking opening on the side of the hull to limit the relative movement of the load and the side of the hull.

[0074] Anti-sway cables: attached to the lifting frame of the cage from both sides, controlled manually / by winch, to suppress swaying / swinging.

[0075] The structural foundation and deck are equipped as follows:

[0076] Type A door foundation: reinforced with longitudinal and transverse frames, with reinforced decks, and equipped with base shear keys and bolt groups.

[0077] Winch base: locally thickened deck and longitudinal girder reinforcement; cable reel facing the guide wheel to ensure cable entry angle.

[0078] Fish retrieval opening: partial opening + load-bearing side bulkhead, roller strips arranged along the edge, short guide rails can be installed inside the opening.

[0079] Safety facilities: work fence, unhooking area markings, operating side guardrail and emergency stop rope.

[0080] Control and power are as follows:

[0081] Electrical control cabinet: winch control, overload protection, limit switches and emergency stop; can be linked with deck camera / tension sensor.

[0082] Power source: Powered by platform generator / wave energy device and rectified and stored before being supplied to the winch; manual or hydraulic emergency recovery is reserved in case of emergency.

[0083] The interface with the two-point mooring and aquaculture system incorporates the lifting operation into the platform stability and mooring tension verification (static / dynamic load calculation) to avoid exceeding the mooring operation window.

[0084] Therefore, this invention adopts a wave energy fishing platform with two-point mooring. The platform is stabilized by using two-point mooring and can be powered by ocean energy and solar energy in a coordinated manner to expand three-dimensional aquaculture capacity. This can break through the bottlenecks of traditional fishing grounds such as "energy dependence, space waste and single function", provide an integrated solution for marine fisheries and ocean energy development, and improve the working efficiency of marine fishery platforms.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
