Description

Technical Field

[0001] This invention relates to the field of marine environmental management equipment technology, and in particular to an optimized design method for marine algae pollution comprehensive management equipment. Background Technology

[0002] Existing patent CN114737542A discloses a method for emergency treatment of seaweed harvested at sea. This method includes steps such as seaweed harvesting, seaweed transfer, seaweed unloading at port, seaweed unpacking and stacking, adding a composting agent, seaweed transfer and release, and marine area monitoring. Utilizing the rapid composting effect of microbial composting agents, the inactive seaweed is released into the sea, effectively treating large quantities of harvested seaweed. This achieves efficient, rapid, and harmless emergency treatment of seaweed harvested at sea, avoiding the environmental pollution problems that may be caused by large-scale seaweed blooms. This method can also employ a process of direct composting on board, enabling on-site treatment of seaweed harvested at sea and reducing intermediate transfer and unloading steps. Finally, the composted seaweed is released into the sea, where it gradually disperses and sinks, completely settling into the sea with ocean currents in about 4-5 hours, without causing secondary pollution to the marine area. It adopts a "1+X" operation mode, using the "Hai Zhuangyuan" (Sea Champion) vessel as the offshore processing platform, with X additional fishing vessels harvesting seaweed. Transporting, unloading, and piling up seaweed in ton bags is not a systematic and orderly method for collecting and storing it. Furthermore, its large size makes it unsuitable for near-shore disposal and hinders subsequent resource utilization. In addition, seaweed requires 24-72 hours to ferment and decompose, which is inconvenient to do directly on the ship.

[0003] Patent CN219364541U discloses an integrated workboat for harvesting, collecting, and processing seaweed on the coast. It includes a floating assembly for movement in water and is sequentially equipped with a cutting and harvesting device, a physical dehydration device, a crushing device, a deactivation device, and a packaging device. When a hydraulic cylinder controls lifting, the seaweed is cut by the side and bottom cutting devices. The boat moves forward, and the seaweed is moved onto a conveyor. Driven by a hydraulic motor, the seaweed is transported to the physical dehydration device via chain transmission. Most of the water is removed through physical compression. The dehydrated seaweed falls into the front chute of the crushing device. Inside the crushing device, the seaweed is cut into small pieces by the high-speed rotation of the rollers. Then, it is evenly fed into the deactivation and drying device. This integrated system offers advantages such as no pollution to the marine or terrestrial environment, improved efficiency, resource utilization, and reduced transportation volume. The living seaweed has an extremely high water content. Even after physical dehydration, the seaweed "mat" still retains a high water content, which means that the inactivation and drying equipment requires a lot of power. As a ship-borne marine operation equipment, this poses a huge challenge to the ship's power requirements for small vessels.

[0004] A journal article titled "A Brief Analysis of Emergency Response Experience for Terrestrial Ulva Prolifera in Qingdao" published two methods: aerobic biochemical treatment and anaerobic digestion treatment. After water control, the Ulva prolifera is mixed with sand and soil. The mixed Ulva prolifera is then piled into strips. During the primary fermentation process, the number of times the piles are turned is controlled based on the internal fermentation temperature. A fast and convenient dedicated temperature measuring instrument is used to measure the temperature of each Ulva prolifera pile daily. The first turning begins when the internal fermentation temperature of the Ulva prolifera pile exceeds 40℃. A second turning is required when the internal fermentation temperature reaches 60℃. After the second turning, if the internal fermentation temperature of the Ulva prolifera pile rises again and reaches 60℃, it needs to be turned again. Turning is stopped when the temperature begins to drop, completing the primary fermentation. For the Ulva prolifera piles that have completed primary fermentation, they can be piled up high for secondary fermentation, depending on site conditions. After secondary fermentation, the Ulva prolifera matures into stable humus. Before the seaweed arrives at the site, the sand needs to be pre-piled into strips. Add the sand and seaweed, mixing them thoroughly. During mixing, simultaneously add adsorbents and anaerobic microbial agents to the seaweed to accelerate its decomposition. After mixing, pile the seaweed into strips, with a height controlled within 3 meters and a width determined by site conditions. The top layer of soil should be at least 0.5 meters thick. No turning is required during anaerobic digestion; turn and mix thoroughly after digestion is complete to achieve full decomposition. After anaerobic digestion, turn the pile again for aerobic digestion within the same year, spraying aerobic microbial agents during this process. Complete stabilization occurs in approximately 2-3 days, and the pile is then stored for seaweed disposal the following year. However, seaweed harvested from the shore must undergo dehydration treatment at designated pressing points before being transported to the emergency disposal site. Furthermore, water control is still necessary after unloading the seaweed.

[0005] Compared with existing emergency treatment technologies for seaweed, it can be found that there are drawbacks such as incomplete dehydration, disconnect and lack of continuity between the stages of harvesting, dehydration and transportation, inefficient operation and uncoordinated power of integrated equipment, and uneven and unsystematic bundling of seaweed. These technologies are difficult to meet the emergency treatment needs of tens of thousands of tons of seaweed harvested, are time-consuming and labor-intensive, and pose a significant risk of secondary environmental pollution. Summary of the Invention

[0006] The purpose of this invention is to provide an optimized design method for marine algae pollution comprehensive treatment equipment, which solves the problems of incomplete dehydration, disconnection and lack of continuity between the stages of salvage, dehydration and transportation, uncoordinated operation of integrated equipment, and uneven and unsystematic bundling of seaweed in marine algae pollution treatment.

[0096] This embodiment takes the development of equipment for dealing with seaweed disasters as an example, and provides an optimized design method for equipment for the comprehensive treatment of seaweed pollution, including the following steps:

[0097] Step 1: Based on the functional requirements, perform digital design and modeling of each functional module to determine the basic structure and layout of the equipment;

[0098] Step 2: Use system-level optimization design techniques to perform power coordination and overall performance optimization;

[0099] Step 3: Use the power transmission matching design method to design and analyze the power transmission system;

[0100] Step 4: Use simulation software to simulate and model the working process of the equipment;

[0101] Step 5: Optimize and verify the equipment based on the simulation results to ensure that the equipment's performance and efficiency meet the expected requirements.

[0103] In step two, the specific power coordination and matching and overall performance optimization methods are as follows:

[0104] Specifically, system-level optimization design software, such as MATLAB and Simulink, is used to perform power coordination and matching and overall performance optimization of the various functional unit modules of the equipment. By establishing a system-level model, parameters of each part of the equipment can be optimized to improve overall efficiency and performance.

[0105] The three essential elements of optimization design are the objective function, design variables, and constraints. The mathematical model, on the other hand, is a mathematical expression used to describe and solve the optimization problem based on these elements.

[0106] Objective function: The objective function of optimization design is an indicator for evaluating the quality of a design solution. The selection of the objective function should be consistent with the design objective and accurately reflect the degree of merit of the design solution.

[0107] Design variables: Design variables are system parameters that can be adjusted and optimized. These include the system's dimensions, shape, materials, and process parameters. The selection of design variables should comprehensively consider the system's performance requirements, manufacturing feasibility, and design space constraints.

[0108] Constraints: Constraints are restrictions on design variables. They can be system performance requirements, engineering limitations, or design specifications. Constraints can include equality constraints and inequality constraints, such as system size limitations, material strength requirements, and manufacturing process requirements.

[0109] A mathematical model is a mathematical expression based on the objective function, design variables, and constraints, used to describe and solve optimization problems. Common mathematical models include linear programming, nonlinear programming, integer programming, and multi-objective optimization. The appropriate mathematical model is selected for modeling and solving based on the specific optimization problem and its characteristics. During the solution process, various optimization algorithms and methods can be used, such as gradient descent, genetic algorithms, particle swarm optimization, and simulated annealing. These algorithms and methods can help find the optimal combination of design variables to achieve the optimization design objective.

[0110] The three elements of optimization design and the mathematical model are key elements in the optimization design process. By reasonably selecting and establishing the mathematical model, optimization design can be carried out effectively and the optimal design solution can be found.

[0114] S203 Define Design Variables: Identify the design variables that need to be optimized, such as the size, material, and operating parameters of each module component. The selection of design variables should comprehensively consider the overall performance requirements and feasibility of the system.

[0115] S204 Determine Constraints: Based on the system's performance requirements and limitations, determine the design constraints. Examples include system size limitations and material strength requirements.

[0116] S205 Establishing an Optimization Model: Based on the system model, design variables, and constraints, establish an optimization design model. Mathematical optimization methods, such as genetic algorithms and particle swarm optimization, can be used to optimize the system.

[0117] S206 performs optimization calculations: Optimization calculations are performed using an optimization model to obtain the optimal combination of design variables. Computer-aided design software can be used for these calculations.

[0118] S207 Evaluation and Optimization Results: Based on the optimization results, evaluate the system's performance and effectiveness. Simulation calculations and experimental verification can be performed.

[0119] S208 optimization and adjustment: Based on the evaluation results, the system is optimized and adjusted. Design variables can be fine-tuned, and optimization calculations can be re-performed until the expected optimization goal is achieved.

[0120] S209 Final Design Scheme: Based on the optimization and adjustments, the final design scheme is obtained. Detailed design and manufacturing can then proceed.

[0158] styi(X)≤0i=1,2,…,8.

[0159] In step three, the powertrain matching design method is used to design and analyze the powertrain system:

[0160] Using specialized powertrain design software, such as SolidWorks and ADAMS, multiple powertrain components (such as generators, transmissions, and motors) are integrated to form a compact and efficient powertrain system, enabling the design and analysis of the equipment's powertrain system. By establishing a powertrain model, the performance and reliability of the transmission system can be evaluated, and the selection and layout of transmission components can be optimized to improve the overall performance, efficiency, and reliability of the transmission system.

[0161] The specific steps include:

[0162] S301, Power Source Integration: Integrating the power source of the generator and motor with the transmission components to form a compact unit; this can reduce the size and weight of the transmission system and improve the overall power density.

[0163] S302, Energy Management: Through an intelligent control system, the power source and transmission components are optimized and managed to achieve close coupling between the power source and transmission system, so as to achieve the best energy conversion and utilization efficiency.

[0164] For example, based on operational needs and working conditions, the power output of generator sets can be rationally scheduled and controlled in real time to ensure that the total power generation of the system meets the load demand, thereby achieving a balance between power supply and demand and optimizing the operation of the system, improving fuel economy and power performance, and minimizing power generation costs and environmental impact.

[0165] S303, Engine Group Power Dispatch: Based on load demand and the characteristics of the motor group, determine the output power of each module motor to meet the total load demand of the system and minimize load costs as much as possible;

[0166] S304, Multi-mode operation: The integrated power transmission design typically supports multiple operating modes; through the intelligent control system, different operating modes are automatically switched according to actual needs and sea conditions to achieve optimal power output and energy utilization;

[0167] S305. Fault Diagnosis and Maintenance: Through sensors and monitoring systems, the operating status of the transmission system is monitored in real time to promptly detect faults and provide corresponding maintenance suggestions, ensuring the reliability and safety of the transmission system. In step four, simulation software, such as MATLAB and Simulink, is used to simulate and model the equipment's working process. By establishing a dynamic model of the equipment, the working process is simulated, and the working effect and coordination of each functional unit are evaluated.

[0168] In step five, the equipment is optimized and verified based on the results of simulation and evaluation. The design parameters of the equipment are adjusted to ensure that its performance and efficiency meet the expected targets.

[0169] like Figure 3-19 As shown, in step one:

[0170] Its operating equipment includes a collection unit 1 for collecting seaweed floating on the sea surface, a salvage unit 2 installed on a water operation platform for collecting seaweed, a filter dehydration unit 4 for dehydrating the seaweed salvaged by the salvage unit 2, and a bundling and wrapping unit 5 for packaging and wrapping the dehydrated seaweed.

[0171] It also includes a transport unit 3 for conveying the seaweed harvested by the salvage unit 2 to the filter press and dewatering unit 4.

[0172] This embodiment describes the following process for the marine treatment of seaweed: Seaweed is collected in a clamping unit at the front of the salvage vessel. A chain conveyor belt in the salvage unit hauls the collected seaweed onto the vessel, where it is then lifted by a transport unit to the required working space height of the filter press dewatering unit. A left-to-right counter-rotating spiral brush is positioned at the end of the transport unit to flatten and homogenize the seaweed entering the wedge-shaped feed inlet of the belt filter press. The seaweed is transported by the filter belt and first undergoes gravity filtration. After passing through the wedge zone, the seaweed is gradually clamped by the upper and lower filter belts for pre-compression dewatering. The seaweed wrapped by the filter belt leaves the wedge zone and enters the pressure zone, where it is dewatered by six pressure rollers. After compression, the seaweed falls from the outlet onto a conveyor belt arranged along the width of the vessel. A fully automatic bundling and wrapping machine is positioned on each side of the conveyor belt, supplying material to the bundling and forming chamber via the left and right sides. After bundling and forming, the seaweed exits the chamber and is sealed and wrapped by the wrapping machine. After being bundled and wrapped, the seaweed is unloaded from the salvage vessel by a transfer unit, stacked, and transported to a designated location for subsequent resource utilization.

[0173] The salvage unit 2 includes a salvage frame 204 hinged to the end of the water operation platform, a chain salvage belt 201 mounted on the salvage frame 204 for salvaging seaweed, and a hydraulic cylinder 202 for adjusting the draft of the lower end of the salvage frame 204; wherein the chain salvage belt 201 is driven to rotate by a drive mechanism 203.

[0174] Specifically, one end of the salvage frame 204 is mounted on one end of the water operation platform via the plate bracket 205;

[0175] In specific applications, the salvage unit 2, such as Figure 8As shown, this unit collects the seaweed and loads it onto the ship, filtering out some seawater by its own weight during the harvesting process. The rear end of the chain-type harvesting belt 201 in harvesting unit 2 is equipped with a hydraulic cylinder 202, which can adjust the draft of the chain-type harvesting belt 201 according to the distribution and thickness of the seaweed in the current harvesting area. The seaweed from the collection unit 1 enters the front end of the chain-type harvesting belt 201. The motor 203 at the rear end of the chain-type harvesting belt 201 provides power to harvesting unit 2. Hydraulic cylinders 202 are installed on both sides of the harvesting frame 204, which can adjust the draft of the front end of the chain-type harvesting belt 201 according to the distribution of the seaweed. When the seaweed is distributed on the surface of the liquid, the hydraulic cylinder 202 extends, and the front end of the chain-type harvesting belt 201 rises to harvest the shallow seaweed; when the seaweed is thicker or farther from the surface, the hydraulic cylinder 202 retracts, and the front end of the chain-type harvesting belt 201 descends to harvest the seaweed at the bottom. Simultaneously, the salvage speed of the chain salvage belt 201 can be adjusted by changing the speed of the motor 203 according to the abundance of the salvage target, which can also increase the ship speed and salvage efficiency. The rear end of the salvage unit 2 is mounted on the bow of the ship via a hydraulic cylinder 202 and a salvage plate bracket 205.

[0176] In this embodiment, a convergence unit 1 is also installed at the lower end of the salvage frame 204;

[0177] The converging unit 1 includes a converging plate frame 102 symmetrically hinged to the lower two side plates of the salvage frame 204, chain plates 104 respectively mounted on the converging plate frame 102, and an adjusting motor 103 mounted on the converging plate frame 102 for driving the chain plates 104 to rotate.

[0178] The converging plate frame 102 is hinged to the lower end of the salvage frame 204 via a converging plate frame bracket 105. A hydraulic cylinder 101 for adjusting the converging deflection of the chain plate 104 is also installed between the salvage frame 204 and the converging plate frame 102.

[0179] The aggregation unit 1, such as Figure 5As shown, this unit collects seaweed on the sea surface. The jaws of the gathering unit are equipped with hydraulic cylinders 101, which can adjust the opening size of the jaws and thus change the retrieval width according to the distribution and thickness of the seaweed in the current retrieval area. Two symmetrical gathering plate frames 102 are equipped with motors 103 that drive the chain plate 104. One end of the hydraulic cylinder 101 is connected to the back of the gathering plate frame 102. Adjusting the hydraulic cylinder 101 can adjust the opening size of the "V"-shaped jaws. When the retrieval target is widely distributed, the hydraulic cylinder 101 retracts, the jaw opening increases, and collection is rapid; when the retrieval target is concentrated and less distributed, the hydraulic cylinder 101 extends, the jaw opening decreases, and power consumption is reduced. At the same time, the speed of the motor 103 can be adjusted according to the distribution of different retrieval targets to adjust the running speed of the chain plate 104, and the boat speed can also be controlled to achieve rapid and efficient collection. The gathering unit 1 is installed at the front end of the retrieval unit 2 via the hydraulic cylinder 101 and the gathering plate frame bracket 105.

[0180] In this embodiment, the transport unit 3 includes a transport unit support 302 installed between the salvage unit 2 and the filter press dewatering unit 4, and a conveyor belt installed on the transport unit support 302 for transferring the seaweed to the filter press dewatering unit 4;

[0181] Side guards are installed on both sides of the conveyor belt in the conveying direction; specifically, the conveyor belt is a skirted baffle conveyor belt; a spiral distributing brush 301 is installed at the end of the conveyor belt to clean the residual seaweed on it; the rotating shaft of the spiral distributing brush 301 is driven by a motor and is installed at the end of the skirted baffle conveyor belt through a bearing seat or bracket, wherein the brush on the spiral distributing brush 301 can penetrate into the skirted baffle conveyor belt;

[0182] The transport unit 3, such as Figure 11 As shown, this unit performs the function of transporting the seaweed from the tail of the harvesting unit 2 to the feed inlet 401 of the belt filter press 4. To make the seaweed more evenly distributed at the feed inlet 401 of the filter press 4, a spiral distribution brush 301 is added to the end of the transport unit 3. The front end of the transport unit 3 faces the rear end of the harvesting unit 2, but the two are not connected. The rear end of the transport unit 3 is installed directly above the feed inlet 401 of the filter press dewatering unit 4 via the transport unit bracket 302. Different materials and structures of conveyor belts are selected according to the characteristics of the material.

[0183] In this embodiment, the filter press dewatering unit 4 includes a belt filter press. One end of the belt filter press is equipped with an inlet 401 for receiving the seaweed transferred from the conveyor belt of the transport unit 3. An extension bracket 404 is installed at the other end of the belt filter press. An outlet 403 for approaching the bundling unit 5 is installed on the extension bracket 404. A distribution conveyor belt 405 for transferring the dewatered seaweed to the feed conveyor belt 501 of the bundling unit 5 is installed below the end side of the outlet 403.

[0184] Dewatering unit 4 is a modified belt filter press, such as Figure 13 As shown, the belt filter press can operate continuously, with adjustable belt tension, uniform pressure distribution, and a wide belt speed adjustment range. It has a good dewatering effect, ensuring that most of the interstitial water in the *Ulva prolifera* "algae mat" is removed without squeezing out the tissue fluid of the *Ulva prolifera*. An extended bracket 404 is provided on the frame 402 below the discharge port 403 at the rear end of the filter press dewatering unit 4 for installing a distribution conveyor belt 405 along the belt width. The distribution conveyor belt 405 feeds the dewatered *Ulva prolifera* in batches to the bundling feed conveyor belt 501.

[0185] In this embodiment, the bundling and wrapping unit 5 includes a water receiving tray 505, a round bundling machine installed above the water receiving tray 505, a feeding conveyor belt 501 that feeds the dehydrated seaweed into the round bundling machine, and a rear wrapping platform 503 for wrapping the seaweed bundles.

[0186] The round baler includes a baling and forming chamber 502 for rolling and pressing dehydrated seaweed into a baling shape, and a rear door 5021 of the forming chamber installed at the rear end of the baling and forming chamber 502; a pneumatic cylinder 504 is also installed below the rear wrapping platform 503 for tilting the wrapped seaweed bales onto the transfer unit 6 at its rear end.

[0187] The bundling and wrapping unit 5, such as Figure 16As shown, after being fully dehydrated by the front-end filter press dewatering unit 4, *Ulva prolifera* can be collected and stored using methods such as ton bags, fully automatic bagging and packaging machines, and fully automatic baling and wrapping machines. However, fully automatic bagging and packaging machines are generally used in factory workshops; these machines are large and heavy, and their packaging process is complex, making them unsuitable for use on ships. For *Ulva prolifera*, using ton bags is even more labor-intensive and cannot systematically and neatly collect and store the prolifera, making transportation inconvenient. Therefore, after considering various solutions, and drawing inspiration from the baling methods of forage and silage, a fully automatic baling and wrapping machine was modified for the collection and processing of *Ulva prolifera*. Its advantages are: the fully automatic baling and wrapping machine achieves full automation in the baling and wrapping of *Ulva prolifera*, enabling efficient collection and processing; its size and weight are suitable for use on seaborne *Ulva prolifera* harvesting vessels; and it can systematically and neatly collect the prolifera, facilitating subsequent resource utilization. A steel roller fixed-cavity baling and forming machine was designed. The feeding conveyor belt 501 feeds the dehydrated seaweed into the forming chamber 502 of the baling machine, where it is rolled, pressed, and shaped. A water receiving tray 505 is provided below. After the rolling and forming is completed, the seaweed is initially formed by wrapping it with a net in the baling and forming chamber 502. Then, the rear door 5021 of the baling and forming chamber is opened to release the initially formed seaweed bundles onto the rear wrapping platform 503. A wrapping machine is installed on the wrapping platform 503 to wrap the seaweed bundles. After wrapping, the wrapping platform 503 is lifted by a pneumatic cylinder 504 to pour the wrapped seaweed bundles onto the rear transfer unit conveyor belt 601.

[0188] In this embodiment, the transfer unit 6 includes an inboard horizontal conveying section 601, an outboard movable conveying section 602 that is transitionally connected to the end of the inboard horizontal conveying section 601 via a connecting block 603, and a hydraulic cylinder 604 that adjusts the deflection and lifting of the outboard movable conveying section 602 relative to the inboard horizontal conveying section 601; wherein conveyor belts for transferring the wrapped seaweed bundles are respectively provided on the inboard horizontal conveying section 601 and the outboard movable conveying section 602.

[0189] The transfer unit 6 is as follows Figure 18 As shown, this unit performs the function of transferring bundled and wrapped seaweed from the work vessel to other locations. The transfer conveyor belt is divided into an internal horizontal conveying section 601 and an external movable conveying section 602, which are hinged together by a connecting block 603. The internal horizontal conveying section 601 is mounted on the deck via a bracket 605. The external movable conveying section 602 is equipped with a hydraulic cylinder 604. When the transfer unit 6 is not in operation, the hydraulic cylinder 604 can be retracted to retract the external movable conveyor belt 602, reducing its area. When the transfer unit 6 is in operation, the hydraulic cylinder 604 extends, laying the external movable conveyor belt 602 flat for transfer operations. The transfer unit 6 is mounted on the stern of the work vessel via mounting feet 605 of the internal horizontal conveyor belt and one end of the hydraulic cylinder 604.
