Description

Technical Field

[0001] The present invention relates to the technical field of seaweed cultivation, in particular to multifunctional seaweed cultivation equipment. Background Art

[0002] Seagrass is a marine-adapted monocotyledonous plant found in shallow, temperate and tropical waters. Seagrass beds are formed by interwoven growth of one or more species of seagrass. As one of the three most prominent marine ecosystems, seagrass beds are essential primary producers in the ocean, boasting exceptionally high productivity and biodiversity. Although they occupy only 0.2% of the ocean's seafloor, they contribute 10% of the world's annual ocean carbon, making them a crucial "blue carbon sink" and playing a vital role in increasing global blue carbon sinks and mitigating global climate change. In addition to its crucial ecosystem functions, seagrass can also be used as compound feed for aquaculture and woven into insulation materials, offering significant economic benefits. However, due to human activities and natural factors, global seagrass beds have been declining since the 1980s. This decline has led to a gradual deterioration of coastal ecosystems. Therefore, seagrass bed restoration is crucial to mitigating this ongoing degradation.

[0003] Currently, the methods used to repair seagrass beds can be divided into three categories: habitat restoration, seed method and transplantation method. The above restoration methods are all based on the colonization of seagrass on the nearshore seabed, which is easily restricted by geographical space and factors such as reclamation projects, nearshore wastewater pollution, extreme weather, etc., causing secondary damage after restoration and bringing losses to the restoration work. Although the above methods have different means, they all need to be carried out on the nearshore seabed and require a certain area of ​​seabed substrate to achieve seagrass cultivation. Therefore, they will be affected by the type of seabed substrate, human occupation, etc., which limits the types and areas of seagrass cultivation. Furthermore, due to the limited nearshore area, simply cultivating seagrass cannot improve the utilization efficiency of the nearshore seabed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art and to propose a multifunctional seaweed cultivation equipment, so that seaweed cultivation is not restricted by the nearshore geographical space, greatly increasing the marine carbon sink per unit area and increasing the economic value of marine fisheries.

[0007] Furthermore, the planting box is arranged inside the planting trough, and rubber pads are provided on the outer walls on both sides of the planting box. The outer sides of the rubber pads are inclined so that the planting box can be inserted between the two upper spiral racks. A slot is provided on the upper outer side of the rubber pad so that the spiral rack can be stuck into the slot.

[0008] Furthermore, a reinforcement is fixedly connected between the upper end of the breeding rack and the connecting frame. The reinforcement includes a support plate and two fixed plates. The two fixed plates are fixedly connected to the breeding rack and the connecting frame respectively. The support plate is fixedly connected between the two fixed plates. The shock absorbing mechanism includes a spring shock absorber. The upper end of the spring shock absorber is connected to the bottom of the breeding rack and the lower end is connected to the outside of the connecting frame.

[0009] Furthermore, the seaweed cultivation mechanism also includes a float, which is conical and arranged inside the connecting frame. An air bag is provided at the bottom of the float, and the air bag is inflated and deflated to change the buoyancy of the seaweed cultivation mechanism.

[0010] Furthermore, the seaweed cultivation mechanism also includes a fixing frame, which is fixedly connected to the bottom of the connecting frame. A plurality of connecting rings are fixedly connected to the fixing frame at intervals, and each buckle is connected to a connecting ring.

[0020] Reference Figure 1-7 , a multifunctional seaweed farming equipment, is used for seaweed farming, in order to facilitate the farming of seaweed in different sea areas and increase the economic value of marine fisheries.

[0021] The multifunctional seaweed cultivation equipment comprises a buoy mechanism 1, a seaweed cultivation mechanism 3, an oyster cultivation mechanism 4 and a counterweight mechanism 5 which are sequentially connected from top to bottom. The buoy mechanism 1 includes a buoy 101, which is used to suspend and secure the device in seawater. Buoy 101 is made of a high-strength, low-density closed-cell foam plastic material, such as polystyrene foam (EPS) or polyurethane foam (PU). This material offers excellent buoyancy, is resistant to seawater corrosion, and has a long service life. Buoy 101 is generally disc-shaped or polyhedral to enhance stability. Multiple independent sealed chambers are provided within buoy 101, ensuring that even if some chambers are damaged, the overall buoyancy is not affected. The surface of buoy 101 is treated with a non-slip and wear-resistant treatment, making it easier for aquaculture personnel to operate on it.

[0022] In some embodiments, a plurality of stabilizing fins are installed at the bottom of the buoy 101. The stabilizing fins are streamlined in design, which can effectively reduce the shaking of the aquaculture equipment under the action of water flow and further improve its stability.

[0023] A fixed box 102 is provided on the buoy 101, a mounting plate 103 is provided on the top of the fixed box 102, the mounting plate 103 is installed horizontally, and a solar panel 104 is provided on the top of the mounting plate 103 for collecting solar energy and converting it into electrical energy for storage to supply power to various components in the device.

[0024] In some embodiments, a transparent cover 1031 is provided on the top of the mounting plate 103 to wrap and protect the solar panel 104 to prevent seawater erosion. The transparent cover 1031 is arc-shaped, which can effectively prevent seabirds and dirt from falling on the transparent cover 1031 and affecting the solar panel 104 from collecting solar energy.

[0025] The buoy mechanism 1 also includes a rope 106 connected to the connector 2. The lower end of rope 106 is connected to the connector 2, and the upper end extends into the interior of the fixed box 102. Inside the fixed box 102, a winding mechanism 105 is housed. Winding mechanism 105 includes a winding motor and a reel secured to the motor's output shaft. The upper end of rope 106 is wound around the reel of winding mechanism 105. By driving the reel through winding mechanism 105, the reel 106 can be retracted and released to adjust the distance between the bottom seaweed farming mechanism 3 and the oyster farming mechanism 4 and the sea surface, ensuring that the seaweed farming mechanism 3 and the oyster farming mechanism 4 are located at an appropriate depth underwater. For example, in shallow waters, the rope length can be shortened to bring the buoy 101 closer to the sea surface, enhancing the solar panel's ability to receive sunlight. In deeper waters, the rope length can be appropriately extended to ensure the seaweed farming mechanism is located in the appropriate water layer.

[0026] The rope 106 is made of ultra-high molecular weight polyethylene, which has extremely high strength and resistance to seawater corrosion, and can maintain a stable connection under harsh sea conditions. The rope 106 is evenly distributed on the edge of the buoy 101 to ensure balanced force.

[0027] In some embodiments, various water quality sensors are distributed and evenly arranged on the buoy 101. Dissolved oxygen sensors, pH sensors, ammonia nitrogen sensors, and phosphate sensors are distributed around the edge of the buoy mechanism 1 to ensure comprehensive monitoring of seawater at different locations, avoid blind spots caused by uneven water flow, and ensure the accuracy and representativeness of water quality data.

[0028] In some embodiments, various water quality sensors use high-precision, corrosion-resistant, and fast-response sensors. For example, the dissolved oxygen sensor uses a fluorescence dissolved oxygen sensor, which has higher measurement accuracy than traditional polarographic sensors, reaching ±0.01 mg / L, is unaffected by changes in seawater salinity, and has strong stability. The pH sensor uses a glass electrode pH sensor, which can achieve a measurement accuracy of ±0.01 pH within a seawater temperature range of -5°C to 60°C, and can accurately sense subtle changes in seawater pH. The ammonia nitrogen sensor uses an ion-selective electrode sensor, with a detection limit of up to 0.01 mg / L for ammonia nitrogen concentration, which can sensitively capture fluctuations in ammonia nitrogen content in seawater. The phosphate sensor uses the principle of molybdenum blue spectrophotometry to accurately measure phosphate concentrations as low as 0.001 mg / L, meeting the needs of precise monitoring of phosphate content in seawater.

[0029] A mounting cavity 107 is located in the center of buoy 101. Inside this cavity 107 are a control module and a communication module. The control module processes and analyzes data collected by the water quality sensor, calculating real-time values ​​for various water quality indicators. These values ​​are then compared with preset suitable water quality ranges to determine whether the seawater values ​​are within the optimal range for seaweed and oyster growth. The communication module enables remote data transmission, meeting the communication needs between the device and an onshore monitoring center.

[0030] In some embodiments, the raw analog signal collected by the water quality sensor is first transmitted to an analog-to-digital conversion unit, which converts it into a digital signal. The digital signal then enters a data preprocessing module, which performs noise removal and filtering to remove abnormal data points caused by factors such as wave fluctuations and electromagnetic interference. The data then enters a data analysis unit, which uses a specific algorithm to analyze the processed data, calculate the real-time values ​​of various water quality indicators, and compare them with preset optimal water quality ranges. For example, a linear regression algorithm can be used to analyze the changing trends of dissolved oxygen data to determine whether it is within the optimal dissolved oxygen range for seaweed and oyster growth (generally 5-8 mg / L).

[0031] In some embodiments, the communication module uses LoRa wireless transmission technology for remote data transmission. LoRa technology features low power consumption and long-distance transmission. In marine environments, its transmission distance can reach several kilometers, meeting the communication needs between aquaculture equipment and onshore monitoring centers. The communication module packages the analyzed water quality data into a specific format and sends it via the LoRa wireless module to the onshore LoRa gateway, which then forwards the data to the monitoring center server. Furthermore, the 4G communication module serves as a backup transmission channel. When the LoRa signal is disrupted by factors such as severe weather, it automatically switches to the 4G network for data transmission, ensuring the stability and continuity of data transmission.

[0032] In some embodiments, the control module sets reasonable threshold ranges for various water quality indicators based on the water quality requirements of seaweed and oysters at different growth stages. For example, for seaweed seedlings, the lower limit for dissolved oxygen is set at 6 mg / L and the upper limit is 7.5 mg / L; the pH range is set between 7.8 and 8.4; the upper limit for ammonia nitrogen is 0.2 mg / L; and the upper limit for phosphate is 0.03 mg / L. As the seaweed and oysters grow, the thresholds are adjusted appropriately to meet the optimal growth requirements of each stage. When the control module detects that a water quality indicator exceeds the set threshold, an alarm system is immediately triggered. This alarm system notifies on-site aquaculture personnel through visible and audible alarms on the aquaculture equipment. Furthermore, the alarm system sends an alert message to the aquaculture manager's mobile device via text message, app push, or other means, detailing the name of the water quality indicator that exceeds the threshold, the current value, and the degree of deviation from the normal range, allowing managers to take timely countermeasures.

[0033] Mounting cavity 107 also houses a lithium-ion battery that stores the electricity generated by solar panels 104. The device's power supply system utilizes a combination of solar energy and lithium-ion batteries. High-efficiency monocrystalline silicon solar panels are used, offering high photoelectric conversion efficiency, reaching 22%-25% under sufficient sunlight conditions. The solar panel area is calculated based on the overall device power consumption. Generally, each square meter of solar panel generates approximately 0.2-0.25 kWh of electricity per hour under standard sunlight intensity (1000 W / ㎡). Lithium-ion iron phosphate batteries are used, offering advantages such as high energy density, long cycle life, and excellent safety. The battery pack capacity is designed based on the monitoring system's daily power consumption and the number of consecutive rainy days in the area, ensuring that the system can maintain normal operation even in the absence of sufficient sunlight for three to five consecutive days. For example, if the monitoring system consumes 2 kWh of electricity per day, a 10-kWh lithium-ion iron phosphate battery pack can meet at least five days of power requirements.

[0034] When the device is exposed to sunlight, solar panels 104 convert solar energy into electricity. Some of this energy directly powers the various components within the device, while the remainder is stored in the lithium battery. When sunlight is insufficient or at night, the lithium battery powers the system, ensuring continuous and stable operation. The power supply system is equipped with an intelligent charge controller that stabilizes and limits the current of the solar panel output, preventing overcharging and over-discharging and preserving the lifespan of the lithium battery. The charge controller also monitors the lithium battery's charge level in real time. When the charge level falls below a set threshold (e.g., 20%), it automatically adjusts system power consumption to prioritize the operation of critical equipment, such as the water quality sensor's data collection and transmission capabilities.

[0035] In some embodiments, to further improve power supply stability, a dual-line redundant backup solution is adopted in the power supply line design. Key equipment such as water quality sensors and control modules are connected to two independent power supply lines. When one line fails, the system automatically switches to the other line for power supply to ensure uninterrupted operation of the equipment. At the same time, the solar panels are regularly cleaned and maintained to remove dust, seaweed and other attachments on the surface to ensure their photoelectric conversion efficiency. The lithium battery pack is regularly charged and discharged for maintenance, and a deep charge and discharge is performed once a quarter to activate battery activity, extend battery life, and ensure the long-term stable and reliable operation of the entire power supply system.

[0036] The seaweed cultivation mechanism 3 is arranged at the bottom of the buoy mechanism 1. The seaweed cultivation mechanism 3 includes a float 301, a connecting frame 302 and a cultivation frame 303. The connecting frame 302 is conical, and its upper part is connected to the connecting piece 2. The float 301 is conical, and the float 301 is arranged at the inner top of the cultivation frame 303. The cultivation frame 303 is conical as a whole and is spirally wrapped around the outside of the connecting frame 302.

[0037] Among them, the seaweed cultivation mechanism 3 is overall conical, with the center of gravity located at the bottom, which can effectively improve its stability in seawater and avoid affecting the growth of seaweed due to wave fluctuations.

[0038] In addition, the spiral-shaped breeding rack 303 can effectively improve the space utilization rate of seaweed breeding, allowing seaweed to fully utilize the three-dimensional space for breeding. The breeding rack 303 is overall conical, and the seaweed at the bottom will not be blocked by the seaweed at the top, which greatly meets the lighting conditions of the seaweed and facilitates the growth of seaweed.

[0039] In some embodiments, to adapt to varying sea conditions and aquaculture needs, an inflatable airbag 305 is provided at the bottom of the float 301. Airbag 305 is inflated and deflated by a gas compressor, allowing precise adjustment of the buoyancy of the float 301. The gas compressor can be installed inside the fixed box 102 and connected to the airbag 305 via a pipe.

[0040] A reinforcement member 6 is fixedly connected between the upper end of the culture rack 303 and the connecting frame 302. The reinforcement member 6 includes a support plate and two fixed plates. The two fixed plates are fixedly connected to the culture rack 303 and the connecting frame 302, respectively. The support plate is fixedly connected between the two fixed plates. The upper end of the culture rack 303 is fixedly connected to the connecting frame 302 via the reinforcement member 6. Because the spiral-shaped culture rack 303 is fixed at the top, it has a certain degree of elasticity as a whole. It will reciprocate up and down like a spring in the waves of the sea. The spring shock absorber 7 can dissipate energy and reduce vibration during the reciprocating movement of the culture rack 303, thereby further improving the stability of the culture rack 303 in the seawater and preventing the fluctuations of the waves from affecting the growth of seaweed.

[0041] A spring shock absorber 7 is provided between the lower end of the breeding rack 303 and the connecting frame 302. The upper end of the spring shock absorber 7 is connected to the bottom of the breeding rack 303, and the lower end is connected to the outer side of the connecting frame 302. When the lower part of the breeding rack 303 shakes up and down, the spring shock absorber 7 can dissipate energy and reduce shock to the breeding rack 303 that shakes up and down.

[0042] The breeding rack 303 is constructed with high-strength and corrosion-resistant metal materials, such as aluminum alloy, which has a strength comparable to that of medium-carbon steel. It can effectively reduce the overall weight while ensuring a stable structure.

[0043] The breeding rack 303 includes two layers of inner and outer brackets. Each layer of the bracket includes two spiral racks 3031 arranged upper and lower. A connecting rod 3032 is fixedly connected between the two spiral racks 3031. The bottom of the two spiral racks 3031 in the lower layer is fixedly connected with a bottom plate 3036, which is spiral-shaped.

[0044] The spiral frames 3031 on either side of the trough and the base plate 3036 form a cultivation trough on the cultivation frame 303. Multiple layers of partitions divide the trough into multiple small areas, each of which can accommodate a seaweed planting box 3033. Each planting box 3033 is arranged along the spiral direction of the cultivation frame 303. Made of high-strength polyethylene (HDPE), the planting trough is 20-30 cm deep and features a large opening at the top, facilitating the planting of seaweed seedlings and the addition of sediment. Each small area can accommodate a single seaweed seedling or a cluster of seedlings, increasing planting density while ensuring that each seaweed plant has its own independent growing space, reducing competition.

[0045] The outer wall of the planting box 3033 is equipped with a resilient rubber pad 3035, and the upper outer portion of the rubber pad 3035 has a slot. Pressing the planting box 3033 downward into the planting slot, it snaps between the inner and outer spiral frames 3031, with the upper spiral frame 3031 snapping into the slot in the rubber pad 3035, securing the planting box 3033. The rubber pad 3035 cushions the connection, reducing the impact of waves on the planting box. The slot design facilitates installation and removal of the planting box 3033. When harvesting seaweed or replacing seedlings, the planting box 3033 can be quickly removed from the cultivation rack 303, improving work efficiency.

[0046] An appropriate amount of sediment is placed inside each planting box 3033. The sediment is selected from nutrient-rich seabed mud or treated artificial synthetic sediment. The thickness of the sediment is generally controlled at 10cm-15cm, which can not only provide a stable attachment basis for the seaweed roots, but also slowly release nutrients such as nitrogen, phosphorus, and potassium to meet the growth needs of seaweed. In order to ensure the nutritional balance and air permeability of the sediment, it is pretreated before placing the sediment. Mix the seabed mud or artificial synthetic sediment with an appropriate amount of lightweight porous materials such as perlite and vermiculite and stir evenly. Perlite and vermiculite can increase the porosity of the sediment, improve air permeability, and facilitate the respiration and growth of the seaweed roots. At the same time, a certain amount of beneficial microbial agents, such as nitrogen-fixing bacteria and phosphate-solubilizing bacteria, are added. These microorganisms reproduce and grow in the sediment, which can further decompose organic matter, release nutrients, and promote the absorption and utilization of nutrients by seaweed.

[0047] In some embodiments, a snap ring 3034 is fixedly connected to the top of the planting box 3033, which allows the planting box 3033 to be clamped on the spiral frame 3031, making it easier to fix the planting box 3033 and also easier to remove it.

[0048] The bottom of the base plate 3036 is fixedly connected with a spiral reinforcement strip 8, which can improve the strength of the breeding rack 303, prevent the breeding rack 303 from being damaged during up and down shaking and deformation, and increase the life of the breeding rack 303.

[0049] A fixing frame 304 is provided at the bottom of the connecting frame 302, effectively enhancing the stability of the connecting frame 302. Multiple connecting rings 406 are evenly distributed at the bottom of the fixing frame 304. The oyster cultivation mechanism 4 includes a suspension rope 401 and a buckle 405. The upper end of the suspension rope 401 is connected to the connecting ring 406 via the buckle 405. The buckle 405 adopts a spring buckle design, which facilitates quick installation, removal, and position adjustment. During installation, the cultivation personnel can flexibly determine the distribution position and hanging depth of the oyster suspension ropes 401 below the cultivation frame based on the light and water conditions required for oyster growth and the ecological needs of symbiosis with seaweed. For example, in areas with slow water flow, the density of the oyster suspension ropes 401 can be appropriately increased to fully utilize the space.

[0050] The connection rings 406 are evenly distributed on the bottom of the fixing frame 304, which can make the oysters more evenly distributed in the culture area and avoid the problem of uneven competition for growth space caused by random hanging.

[0051] In some embodiments, to reduce the impact of waves and currents on oyster growth, a buffer mechanism is added at the connection between the connecting buckle 405 and the suspension rope 401. The buffer mechanism includes a movable rod 402, a fixed cylinder 403, a movable plate 404, and two springs 407. The upper end of the fixed cylinder 403 is fixedly connected to the buckle 405, and the movable plate 404 is slidably connected to the interior of the fixed cylinder 403. The upper end of the movable rod 402 is fixedly connected to the movable plate 404, and the lower end is fixedly connected to the suspension rope 401. The two springs 407 are respectively provided at the upper and lower ends of the movable plate 404. The upper and lower parts of the fixed cylinder 403 are provided with water holes 4031. When the impact of waves causes the suspension rope 401 to be stressed, the suspension rope 401 will pull the movable plate 404 through the movable rod 402, causing the movable plate 404 to move inside the fixed tube 403. When the movable plate 404 moves downward, the spring 407 at the bottom of the movable plate 404 is compressed, and the movable plate 404 will squeeze the seawater at its bottom out of the fixed tube 403 through the water hole 4031, absorbing energy, thereby reducing the impact force on the suspension rope 401 and reducing the impact on the oyster attachment base.

[0052] In some embodiments, tension sensors are installed at the connection between the mounting bracket 304 and the suspension rope 401 to monitor the rope tension and changes in the weight of the oyster accretion matrix in real time. These tension sensors transmit data via a communication module to the farmer's mobile device or the central control system of the aquaculture equipment. For example, if the tension in the suspension rope 401 increases abnormally, it may indicate that the oysters are growing too densely or are being impacted by abnormal water flow. The system will promptly issue an alarm, prompting the farmer to check and make adjustments. By monitoring changes in the accretion matrix weight, the growth rate of the oysters can be estimated, providing data support for aquaculture management and achieving precise aquaculture.

[0053] The counterweight mechanism 5 includes a counterweight plate 501, which is provided with a plurality of shackles 502 at intervals. Each suspension rope 401 is provided with a hook 408 at its lower end, each hook 408 being hooked onto a shackle 502. The counterweight plate 501 provides a counterweight and secures each suspension rope 401, preventing it from swaying. The counterweight plate 501 is made of a high-density lead alloy with an anti-corrosion treatment to ensure compatibility with seawater environments.

[0054] The weight of the counterweight plate 501 is precisely calculated and configured based on the overall weight of the aquaculture equipment, the buoyancy of the float, and the desired immersion depth, allowing for flexible control of the immersion depth of the entire seaweed aquaculture equipment. For example, in the summer, when the surface temperature of the seawater is too high, a heavier counterweight plate 501 is used to allow the equipment to sink to a water layer with a suitable temperature. During the seaweed seedling stage, the equipment is placed at a shallower depth, and the immersion depth is gradually increased as the seaweed grows. Simultaneously, the equipment uses water pressure sensors installed at different depths to monitor the actual immersion depth in real time and feed this data back to the control module for precise control. If the water pressure sensor detects that the actual immersion depth deviates from the set depth by more than the allowable range, the control module automatically activates the adjustment device, which, through the winding mechanism 105, returns the equipment to the set immersion depth.

[0055] In some embodiments, multiple devices can be combined to form a multi-region farm. The devices in each region are linked through a communication module to achieve adaptive depth adjustment and zoning aquaculture management. The aquaculture area is divided into multiple sub-regions based on the differences in environmental parameters such as water quality, water temperature, and light in different regions. The control module accurately adjusts the length of the oyster hanging rope 401 in different sub-regions according to the growth stage and environmental requirements of the oysters in each sub-region. For example, in areas with sufficient light but high water temperature, the length of the oyster hanging rope 401 is appropriately reduced to ensure that the oysters are in a water layer with a suitable temperature; in areas with fast water flow and rich nutrients, the density of the oyster hanging rope 401 is increased to fully utilize resources. Through this zoning aquaculture management model, the overall growth quality and aquaculture efficiency of oysters are improved.

[0056] In some embodiments, the device also includes a remote monitoring and data analysis system that aggregates and analyzes various monitoring data (such as the tension of the suspension rope 401, oyster growth rate, and environmental parameters). Farmers can access this platform anytime, anywhere via mobile phones, computers, and other devices to obtain real-time information on oyster growth and the aquaculture environment. The data analysis platform utilizes big data analytics and artificial intelligence algorithms to mine and analyze historical data, predict oyster growth trends, identify potential aquaculture risks (such as disease outbreaks and environmental degradation), and provide corresponding early warnings and management recommendations. For example, by analyzing historical water quality and oyster growth data, it can predict water quality issues that may arise in a specific area during a specific season, allowing for proactive adjustments to aquaculture strategies and ensuring smooth oyster aquaculture.
