Description

Technical Field

[0001] This invention relates to the field of seaweed aquaculture technology, and more particularly to a suspended seaweed aquaculture device. Background Technology

[0002] Seagrass is a monocotyledonous plant adapted to marine environments, growing in temperate and tropical shallow waters. One or more types of seagrass intertwine to form seagrass beds. As one of the three major marine ecosystems, seagrass beds are indispensable primary producers in the ocean, possessing extremely high productivity and biodiversity, playing a vital role in increasing global blue carbon sinks and mitigating global climate change. Besides its important ecosystem functions, seagrass can also be used to make compound feed for aquaculture and woven into insulation materials, offering certain economic benefits. However, due to human activities and natural factors, global seagrass beds are on a trend of degradation, and with their decline, coastal ecosystems are gradually deteriorating. Therefore, seagrass bed restoration is of great significance in mitigating the continued degradation of seagrass beds.

[0003] Currently, the main methods for restoring seagrass beds are adult transplantation and seed cultivation. Seed cultivation involves directly growing seagrass beds from seeds to restore them. However, seagrass seeds are small and light, making them difficult to fix and easily washed away by seawater, resulting in challenges in seed cultivation. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a suspended seaweed aquaculture device that facilitates the fixed growth of seaweed seeds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A suspended seagrass aquaculture device, comprising: buoy; The seaweed farming apparatus is located at the bottom of the buoy. The seaweed farming apparatus includes a suspension cylinder with a spiral plate on the outside. Multiple farming basins are arranged on the spiral plate along the spiral direction. The top of the spiral plate is fixed to the outer wall of the suspension cylinder. The bottom of the spiral plate is equipped with a drive mechanism to make the spiral plate retract upward, thereby sealing the top of the farming basins. The drive mechanism includes a moving ring and a winch. The moving ring is slidably connected to the outside of the suspension cylinder. One side of the moving ring is fixedly connected to the bottom of the spiral plate. The winch is set on the buoy. The winch reel is equipped with a pull rope, and the lower end of the pull rope is connected to the moving ring. Oyster farming facilities are located at the bottom of seaweed farming facilities and consist of multiple evenly distributed suspension ropes for cultivating aquatic products.

[0006] Furthermore, the lower surface of the spiral plate is provided with a baffle, which is located above the culture basin and the size of the baffle is the same as that of the culture basin, so that the baffle seals the top of the culture basin and the inside of the culture basin contains sediment.

[0007] Furthermore, both sides of the suspension cylinder are provided with strip-shaped openings, and the moving ring is provided with a connecting rod. The two ends of the connecting rod pass through the two strip-shaped openings respectively, and the lower end of the pull rope is fixedly connected to the connecting rod.

[0008] Furthermore, the upper and lower ends of the spiral plate are provided with reinforcement members. The upper reinforcement member is fixedly connected to the outer wall of the suspension cylinder, and the lower reinforcement member is fixedly connected to the outer wall of the moving ring.

[0009] Furthermore, a connector is provided between the buoy and the suspension tube. The suspension tube is hollow inside and contains an air bladder. A gas compressor is provided on the buoy to inflate the air bladder.

[0010] Furthermore, the buoy is equipped with a float plate on top, which protrudes above the water surface. A solar panel is installed above the float plate, and a transparent cover with an arc shape is installed on top of the float plate.

[0011] Furthermore, the buoy consists of two cylindrical parts, with the diameter of the upper cylinder being larger than that of the lower cylinder. A through hole is provided in the middle of the buoy, and an installation box is located inside the through hole. The installation box contains a battery, a control module, a data processing module, and a transmission module. Multiple water quality sensors are evenly arranged on the buoy.

[0012] Furthermore, the bottom of the suspension cylinder is equipped with a support, and multiple connecting rings are evenly distributed at the bottom of the support. Each suspension rope has a spring buckle at its upper end, and the spring buckle is connected to a connecting ring.

[0013] Furthermore, a counterweight is installed at the lower end of each rope.

[0014] The beneficial effects of this invention are as follows: In this invention, a suspended seaweed cultivation device cultivates seaweed in cultivation basins mounted on a spiral plate. After the seaweed seeds are sown, the spiral plate is retracted, shortening the distance between the upper and lower layers. This provides shade over the top of the cultivation basin, ensuring the seaweed seedlings take root, improving their survival rate, and preventing waves from affecting their initial growth. Once the seaweed seedlings have grown for a certain period, the spiral plate can be extended downwards, increasing the distance between adjacent upper and lower layers and providing more growing space for the seaweed in the cultivation basin.

[0015] Oysters are cultured on the lower part of the seagrass using hanging ropes. Plant debris produced during seagrass cultivation serves as a food source for the oysters, placing them in a location that neither interferes with seagrass growth nor hinders their access to suitable water flow and food, thus promoting the synergistic growth of seagrass and oysters. This system integrates seagrass cultivation and aquaculture, increasing both the carbon sequestration capacity of seagrass and the economic value of marine fisheries within the same unit area. Furthermore, the various water quality sensors within the equipment also enable it to perform marine environmental monitoring. Attached Figure Description

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0022] Reference Figure 1-5 A suspended seagrass aquaculture device is used in seagrass farming to facilitate the fixation and growth of seagrass seeds, improve the survival rate, and increase the economic value of marine fisheries.

[0023] The suspended seagrass farming equipment includes a buoy mechanism, a seagrass farming mechanism, and an oyster farming mechanism connected from top to bottom. The buoy mechanism includes a float 1 and a buoy 2. The float 1 is located on top of the buoy 2 and protrudes above the water surface. The buoy 2 provides a float to suspend the seagrass farming structure and oyster farming structure at its bottom in the water.

[0024] In some embodiments, a solar panel 101 is provided above the float 1 for collecting solar energy and converting it into electrical energy for storage to power the equipment. A transparent cover 102 is provided on the top of the float 1 to wrap and protect the solar panel 101 from seawater erosion. The transparent cover 102 is arc-shaped, which can effectively prevent seabirds and dirt from falling on the transparent cover 102 and affecting the solar panel 101's ability to collect solar energy.

[0025] The solar panels are high-efficiency monocrystalline silicon solar panels, which have high photoelectric conversion efficiency, reaching 22%-25% under sufficient sunlight. The solar panel area is calculated and configured based on the power consumption of the entire system. Generally, each square meter of solar panel can generate approximately 0.2-0.25 kWh of electricity per hour under standard light intensity (1000W / ㎡). The lithium batteries are lithium iron phosphate batteries, which have advantages such as high energy density, long cycle life, and good safety. The battery pack capacity is designed based on the daily power consumption of the monitoring system and the number of consecutive cloudy or rainy days in the local area, ensuring that the system can still operate normally even after 3-5 consecutive days without sufficient sunlight. For example, if the monitoring system consumes 2 kWh of electricity per day, a 10 kWh lithium iron phosphate battery pack can meet the power needs for at least 5 days.

[0026] When there is sunlight, the solar panel 101 converts solar energy into electrical energy. Part of this electricity directly powers the components within the device, while the remaining energy 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 charging controller, which regulates the voltage and current of the solar panel output to prevent overcharging and over-discharging, thus protecting the lithium battery's lifespan. The charging controller also monitors the lithium battery's charge status in real time. When the charge level falls below a set threshold (e.g., 20%), it automatically adjusts the system's power consumption, prioritizing the operation of critical equipment, such as the water quality sensor's data acquisition and transmission functions.

[0027] In some embodiments, to further improve power supply stability, a dual-line redundancy backup scheme is adopted in the power supply line design. Major 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 to ensure uninterrupted operation of the equipment. Simultaneously, the solar panels are regularly cleaned and maintained to remove dust, algae, and other deposits, ensuring their photoelectric conversion efficiency. The lithium battery pack undergoes regular charge-discharge maintenance, with a deep charge-discharge cycle performed quarterly to activate battery activity, extend battery life, and ensure the long-term stable and reliable operation of the entire power supply system.

[0028] Buoy 2 is made of high-strength, low-density closed-cell foam plastic material, such as polystyrene foam (EPS) or polyurethane foam (PU). This material has excellent buoyancy performance, is resistant to seawater corrosion, and has a long service life.

[0029] Buoy 2 consists of two cylindrical parts, with the upper cylinder having a larger diameter than the lower cylinder to maintain stability in the water. Buoy 2 also features multiple independent sealed chambers, ensuring overall buoyancy even if some chambers are damaged. The surface of buoy 2 is treated with a non-slip, wear-resistant finish for easy operation by aquaculture personnel.

[0030] In some embodiments, multiple stabilizing fins are installed at the bottom of the buoy 2. The stabilizing fins are streamlined in design, which can effectively reduce the swaying of the aquaculture equipment under the action of water flow and further improve its stability.

[0031] In some embodiments, the buoy 2 has a through hole in the middle, and a mounting box 16 is provided inside the through hole. The mounting box 16 is provided with a storage battery, which can power the components in the device. The electrical energy converted by the solar panel 101 can be stored by the storage battery.

[0032] In some embodiments, various water quality sensors are distributed and uniformly arranged on buoy 2. Dissolved oxygen sensors, pH sensors, ammonia nitrogen sensors, and phosphate sensors are distributed at the edge of buoy 2 to ensure comprehensive monitoring of seawater at different locations, avoid monitoring blind spots caused by uneven water flow, and ensure the accuracy and representativeness of water quality data.

[0033] Various water quality sensors utilize high-precision, corrosion-resistant, and fast-response sensors. For example, the dissolved oxygen sensor employs a fluorescence-based method, offering higher measurement accuracy (to ±0.01 mg / L) compared to traditional polarographic sensors. It is also unaffected by changes in seawater salinity and exhibits strong stability. The pH sensor uses a glass electrode type, achieving a measurement accuracy of ±0.01 pH within a seawater temperature range of -5℃ to 60℃, precisely detecting subtle changes in seawater pH. The ammonia nitrogen sensor employs an ion-selective electrode method, achieving a detection limit of 0.01 mg / L for ammonia nitrogen concentration, sensitively capturing fluctuations in ammonia nitrogen content in seawater. The phosphate sensor utilizes the molybdenum blue spectrophotometric principle, accurately measuring phosphate concentrations as low as 0.001 mg / L, meeting the requirements for precise monitoring of phosphate content in seawater.

[0034] In some embodiments, the mounting box 16 contains a control module, a data processing module, and a transmission module. The data processing module processes and analyzes the data collected by the sensors, calculates the real-time values ​​of various water quality indicators, and compares them with preset suitable water quality ranges to determine whether the values ​​in the seawater are within the optimal range for seagrass and oyster growth. The transmission module enables remote data transmission to meet the communication needs between the device and the onshore monitoring center.

[0035] The control module processes and analyzes the data collected by the water quality sensors, calculates the real-time values ​​of various water quality indicators, and compares them with preset suitable water quality ranges to determine whether the values ​​in the seawater are within the optimal range for seagrass and oyster growth. The communication module enables remote data transmission, meeting the communication needs between the equipment and the onshore monitoring center.

[0036] The raw analog signals collected by the water quality sensor are first transmitted to the analog-to-digital converter (ADC) to convert them into digital signals. The digital signals then enter the data preprocessing module, which performs noise reduction and filtering to remove abnormal data points caused by factors such as wave fluctuations and electromagnetic interference. Next, the data enters the data analysis unit, where specific algorithms are used to analyze the processed data, calculate the real-time values ​​of various water quality indicators, and compare them with preset suitable water quality ranges. For example, a linear regression algorithm is used to analyze the trend of dissolved oxygen data to determine whether it is within the optimal dissolved oxygen range for seagrass and oyster growth (generally 5-8 mg / L).

[0037] In some embodiments, the communication module employs 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 data packets of a specific format and sends them to the onshore LoRa gateway via the LoRa wireless module. The gateway then forwards the data to the monitoring center server. Simultaneously, a 4G communication module is used as a backup transmission channel. When the LoRa signal is interfered with by factors such as severe weather, the system automatically switches to the 4G network for data transmission, ensuring the stability and continuity of data transmission.

[0038] In some embodiments, the control module sets reasonable threshold ranges for various water quality indicators based on the water quality requirements of seagrass and oysters at different growth stages. For example, for seagrass seedlings, the lower limit of dissolved oxygen is set at 6 mg / L, and the upper limit at 7.5 mg / L; the pH range is set between 7.8 and 8.4; the upper limit of ammonia nitrogen is 0.2 mg / L; and the upper limit of phosphate is 0.03 mg / L. As seagrass and oysters grow, the thresholds are adjusted in a timely manner to meet their optimal growth needs at different stages. When the control module detects that a water quality indicator exceeds the set threshold, it immediately triggers the alarm system. The alarm system emits a clear audible and visual alarm on the aquaculture equipment to alert on-site personnel. Simultaneously, it sends alarm information to the mobile terminals of aquaculture managers via SMS, APP push notifications, etc., detailing the name of the water quality indicator exceeding the threshold, its current value, and the degree of deviation from the normal range, so that managers can take timely countermeasures.

[0039] The seagrass cultivation facility includes a suspension cylinder 4, with a spiral plate 8 on its exterior. The top of the spiral plate 8 is fixed to the outer wall of the suspension cylinder 4, while the bottom is movable, allowing the bottom of the spiral plate 8 to move up and down, thus enabling it to be expanded and retracted. Multiple cultivation basins 9 are mounted on the spiral plate 8, spirally arranged along it. Seagrass can be cultivated inside the cultivation basins 9. During seagrass cultivation, seagrass seedlings are first planted in the cultivation basins 9. Then, the spiral plate 8 is retracted, reducing the distance between adjacent upper and lower layers. Therefore, in the early stages of seagrass seedling growth, the upper spiral plate 8 can shield the cultivation basins 9 on the lower spiral plate 8, ensuring the seagrass seedlings take root, improving their survival rate, and preventing waves from affecting their initial growth. After the seagrass seedlings have grown for a certain period, the spiral plate 8 can be stretched downwards, increasing the distance between adjacent upper and lower layers and providing more growing space for the seagrass in the cultivation basins 9.

[0040] The lower surface of the spiral plate 8 is provided with a baffle 10. The baffle 10 is located above the culture basin 9 and its size is the same as that of the culture basin 9. It can make the spiral plate 8 retract upwards, and when the distance between the two adjacent layers is reduced, the baffle 10 blocks the top opening of the culture basin 9, thereby protecting the seaweed seedlings inside the culture basin 9, preventing the roots from being affected by the waves and also preventing them from being eaten by fish.

[0041] The culture basin 9 is made of high-strength polyethylene (HDPE), which has good corrosion resistance and flexibility. The culture basin 9 is 20cm-30cm deep and has a large opening at the top, which makes it easy to plant seaweed seedlings and add sediment.

[0042] Each culture container (9) contains an appropriate amount of sediment. The sediment should be nutrient-rich seabed silt or treated synthetic sediment. The sediment thickness is generally controlled at 10-15 cm, providing a stable attachment base for seagrass roots and slowly releasing nutrients such as nitrogen, phosphorus, and potassium to meet the seagrass' growth needs. To ensure nutritional balance and aeration, the sediment is pre-treated before placement. The seabed silt or synthetic sediment is mixed with appropriate amounts of lightweight, porous materials such as perlite and vermiculite, and stirred thoroughly. Perlite and vermiculite increase the porosity of the sediment, improving aeration and promoting seagrass root respiration and growth. Simultaneously, a certain amount of beneficial microbial agents, such as nitrogen-fixing bacteria and phosphate-solubilizing bacteria, are added. These microorganisms multiply and grow in the sediment, further decomposing organic matter, releasing nutrients, and promoting nutrient absorption and utilization by the seagrass.

[0043] A connector 201 is provided between the buoy 2 and the suspension cylinder 4, which can be used to connect and fix the buoy 2 and the suspension cylinder 4.

[0044] The suspension cylinder 4 is hollow inside, and an air bladder 17 is installed inside the suspension cylinder 4 to provide buoyancy. In order to adapt to different sea conditions and aquaculture needs, the air bladder 17 can be inflated and deflated. The air bladder 17 can be inflated and deflated by a gas compressor installed inside the mounting box 16, thereby precisely adjusting the buoyancy of the suspension cylinder 4.

[0045] A movable ring 12 is slidably connected to the outside of the suspension cylinder 4. One side of the movable ring 12 is fixedly connected to the bottom of the spiral plate 8. A connecting rod 13 is provided on the movable ring 12. Both sides of the suspension cylinder 4 are provided with strip-shaped openings, and the two ends of the connecting rod 13 pass through the two strip-shaped openings respectively. The connecting rod 13 moves up and down inside the two strip-shaped openings, which can drive the movable ring 12 to move up and down outside the suspension cylinder 4, thereby stretching or contracting the spiral plate 8.

[0046] The mounting box 16 contains a winch 15, and the winch 15 has a pull rope 14 on its reel. The lower end of the pull rope 14 is connected to the connecting rod 13. When the winch 15 winds up the pull rope 14, the pull rope 14 pulls the moving ring 12 upward, thereby causing the spiral plate 8 to retract. When the winch 15 releases the pull rope 14, the spiral plate 8 automatically and naturally unfolds downward due to its own gravity.

[0047] The spiral plate 8 is provided with a reinforcing member 11 at both the upper and lower ends. The upper reinforcing member 11 is fixedly connected to the outer wall of the suspension cylinder 4, and the lower reinforcing member 11 is fixedly connected to the outer wall of the moving ring 12.

[0048] Both the suspension cylinder 4 and the spiral plate 8 are constructed using high-strength, corrosion-resistant metal materials, such as aluminum alloy, which has a strength comparable to medium carbon steel. This effectively reduces the overall weight while ensuring structural stability.

[0049] The oyster farming facility consists of multiple evenly distributed hanging ropes 6 on which oysters can be farmed.

[0050] The bottom of the suspension cylinder 4 is equipped with a support 5, and multiple connecting rings are evenly distributed at the bottom of the support 5. The upper end of the oyster hanging rope 6 in the oyster farming structure is connected to the connecting rings through a connecting buckle. The connecting buckle adopts a spring-loaded buckle design for easy installation, disassembly, and position adjustment. During installation, the farming personnel can flexibly determine the distribution position and suspension depth of the oyster hanging rope 6 under the farming frame according to the light and water flow conditions required for oyster growth and the ecological needs of symbiosis with seaweed.

[0051] Multiple connecting rings are evenly distributed at the bottom of the support 5, which can make the oysters more evenly distributed in the farming area and avoid the problem of uneven competition for growth space caused by random hanging.

[0052] In some embodiments, a tension sensor is installed at the connection between the support 5 and the suspension rope 6 to monitor information such as the tension of the suspension rope and changes in the weight of the oyster substrate in real time. These tension sensors transmit data to the mobile terminal of the aquaculture personnel or the central control system of the aquaculture equipment via a communication module. For example, when the tension of the suspension rope 6 increases abnormally, it may indicate that the oyster growth density is too high or that it is being impacted by abnormal water flow. The system will promptly issue an alarm to remind the aquaculture personnel to check and make adjustments. By monitoring changes in the weight of the substrate, the growth rate of the oysters can be estimated, providing data support for aquaculture management and enabling precision aquaculture.

[0053] A counterweight 7 is installed at the bottom of the lifting rope 6 to prevent the rope 6 from swaying. The counterweight 7 is made of high-density lead alloy and has been treated with anti-corrosion coating to adapt to the seawater environment.

[0054] The weight of counterweight 7 is precisely calculated and configured based on the overall weight of the aquaculture equipment, the buoyancy of the float, and the required water depth, allowing for flexible control of the seagrass aquaculture equipment's water depth. For example, in summer when the seawater surface temperature is too high, a heavier counterweight 7 is used to allow the equipment to sink to a suitable water layer; during the seagrass seedling stage, the equipment is placed at a shallower depth, gradually increasing the water depth as the seagrass grows. Simultaneously, the equipment monitors the actual water depth in real time through water pressure sensors installed at different depths, feeding the data back to the control module for precise adjustment. When the water pressure sensor detects a deviation between the actual water depth and the set depth exceeding the allowable range, the control module automatically activates the adjustment device, changing the buoyancy through airbag 17, thereby restoring the equipment to the set water depth.

[0055] In some embodiments, multiple devices can be combined to form a multi-regional aquaculture farm. The devices in each region are linked via a communication module to achieve adaptive depth adjustment and zoned aquaculture management. Based on differences in environmental parameters such as water quality, water temperature, and light intensity in different regions, the aquaculture area is divided into multiple sub-regions. The control module precisely adjusts the length of the oyster hanging ropes 6 in each sub-region according to the oyster's growth stage and environmental requirements. For example, in areas with ample sunlight but high water temperature, the length of the oyster hanging ropes 6 is appropriately reduced to keep the oysters in a suitable water layer; in areas with fast-flowing water and abundant nutrients, the density of the oyster hanging ropes 6 is increased to fully utilize resources. This zoned aquaculture management model improves the overall growth quality and aquaculture efficiency of oysters.

[0056] In some embodiments, the equipment also includes a remote monitoring and data analysis system, which summarizes and analyzes various monitoring data from the equipment (such as rope tension, oyster growth rate, environmental parameters, etc.). Aquaculture personnel can access the platform anytime, anywhere via mobile phones, computers, and other terminal devices to monitor oyster growth and aquaculture environment information in real time. 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 warnings and management suggestions. For example, by analyzing historical water quality data and oyster growth data, it can predict potential water quality problems in a specific region during a particular season, allowing for timely adjustments to aquaculture strategies and ensuring the smooth operation of oyster farming.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
