Description

Technical Field

[0001] This invention relates to the technical field of integrated aquaculture, specifically a method and apparatus for integrated aquaculture driven by renewable energy. Background Technology

[0002] "Lucid waters and lush mountains are invaluable assets" is an environmental protection concept with profound significance. It not only helps us protect the environment but also promotes economic development. In recent years, the country has attached great importance to promoting the green, efficient, and sustainable development of fisheries. At the same time, the increasingly stringent ecological and environmental protection supervision has also forced traditional aquaculture production methods, which are characterized by limited aquaculture areas, high water consumption, low output per unit area, and unstable wastewater quality, to urgently need to be upgraded to adapt to appropriate development.

[0003] While factory-style indoor recirculating aquaculture and land-based circular pond aquaculture can reduce water consumption, increase output per unit area, and ensure effluent meets discharge standards, the wastewater from factory-style indoor recirculating aquaculture ponds is treated by the grid's daily electricity supply or high-power generators to power microfilters, protein skimmers, microbial treatment systems, and aeration equipment, or by using sedimentation tanks, beneficial bacteria purification tanks, and aeration tanks before being reinjected into the aquaculture ponds for reuse. Land-based circular pond aquaculture also uses the grid's daily electricity supply or high-power generators to keep related facilities and equipment running continuously for treating and recycling aquaculture wastewater, and typically employs a single-species farming model for large-scale production.

[0004] The above-mentioned aquaculture technology models have their own shortcomings: First, the cost of wastewater treatment equipment is high, and its operation is costly; power outages and equipment failures can easily cause large-scale losses. Second, the related equipment occupies a large area and often requires the destruction of the original site for construction, resulting in high relocation costs for fixed facilities. Finally, there is very little integration with crop farming for the sustainable resource utilization of aquaculture wastewater, making it difficult to form a closed-loop production system between aquaculture and agricultural planting to achieve a win-win effect. Moreover, expanding the scale of production is subject to restrictions on arable land boundaries and aquaculture water area planning.

[0005] To promote innovation in aquaculture methods, meet the demands of facility-based fisheries, ecological fisheries, and sustainable fisheries, and address people's health and wellness needs for high-quality agricultural products, improve resource utilization and production efficiency per unit area, and effectively utilize various idle site resources in a way that is not limited by arable land boundaries or aquaculture water area planning, and can cover non-traditional and traditional aquaculture spaces such as deserts, barren areas, intertidal zones, offshore platforms, and ocean-going ship decks, it is necessary to develop an ecological, zero-emission, three-dimensional aquaculture technology. Some publicly available literature also reports on ecological three-dimensional aquaculture devices, excerpts of which are cited below:

[0008] 3. Chinese Patent: Three-Dimensional Integrated Planting and Cultivation Device, Application No.: 201520879866.4, Application Date: 2015.11.06, Abstract: This utility model discloses a three-dimensional integrated planting and cultivation device, which includes a frame and at least one planting and cultivation device mounted on the frame. The planting and cultivation device includes an installation component, which is equipped with a planting layer for planting plants, pipes for providing water to the plants, and supplemental lighting for providing light to the plants. The frame is equipped with a control module for controlling the pipes and supplemental lighting. This three-dimensional integrated planting and cultivation device creates a good growing environment for plants and automates watering and lighting. A single integrated device can be used indoors as a decorative vertical greening solution, or multiple integrated devices can be combined to form a vertical green wall, beautifying the indoor environment and creating fresh air.

[0009] Applied research has revealed that different aquatic species adapt to different growing environments; some prefer shade, while others prefer sunlight. The three-dimensional aquaculture technologies disclosed in references 1-3 cannot be adjusted to provide shade or light based on the specific needs of the aquatic species. Furthermore, the yield of climbing, shade-loving, high-value aquatic animals per unit area is low, resulting in low economic benefits. Moreover, the three-dimensional aquaculture technologies disclosed in references 1 and 2 require the use of waste collection and filtration equipment; the technology disclosed in reference 3 is only suitable for indoor ornamental aquaculture and not for commercial aquaculture. Additionally, solar and wind power generation technologies are relatively mature. Applying solar and / or wind power generation technologies to three-dimensional aquaculture could reduce operating costs and improve economic efficiency. Therefore, a new three-dimensional aquaculture technology needs to be developed. Summary of the Invention

[0010] The purpose of this invention is to provide a renewable energy-driven three-dimensional farming method and apparatus. This three-dimensional farming technology combines renewable energy applications, which can reduce operating costs, eliminate the need for waste collection and filtration equipment, and eliminate the need for external sewage discharge during the farming process. While improving economic efficiency, it can be applied to sites unsuitable for traditional aquaculture, such as slopes, rooftops, and gravelly wastelands. It also provides convenience for farmers and residents to farm in their own courtyards, making full use of space for efficient farming and increasing the output of farmed products per unit area. Moreover, it can be converted into a shaded or light-transmitting farming environment according to the needs of farming.

[0011] This invention is achieved using the following technical solution:

[0012] A renewable energy-driven integrated farming method includes the following steps:

[0013] Step 1: Construct a three-dimensional ecological farming device and a floating aquaculture device. The three-dimensional ecological farming device includes a farming pond frame. Inside the farming pond frame, scraped cloth water bags for holding water are fixedly installed. The scraped cloth water bags are custom-made according to the inner dimensions of the farming pond frame. After being placed inside the farming pond frame, polyethylene ropes are threaded through the fixing holes on the opening edge and wrapped around and fixed to the four horizontal square tubes above the farming pond frame to ensure they do not slip. Two parallel guide rails are connected to the bottom of the two outer sides of the farming pond frame. Sliding planting frames are slidably installed on the guide rails via pulleys. The length of the guide rails is greater than the side length of the farming pond frame, ensuring that the sliding planting frames can slide to cover the top of the farming pond frame and slide away from the top of the farming pond frame. Multiple planting tubes are horizontally arranged from high to low on the sliding planting frame. These multiple planting tubes are connected in series via connecting pipes, forming a loop-shaped water flow channel. The highest planting tube is connected to a water suction pipe extending into the bottom of the scraper cloth water bag, and the water suction pipe is connected to a water pump. The lowest planting tube is connected to a return pipe extending into the scraper cloth water bag. An atomizing nozzle is installed on the sliding planting rack, and the atomizing nozzle is connected to a spray water delivery pipe extending into the scraper cloth water bag, which is connected to a spray delivery pump. A photovoltaic panel mounting frame is installed on the sliding planting rack, and photovoltaic panels are installed on the photovoltaic panel mounting frame. The photovoltaic panels are connected to a power control box, which is installed inside the photovoltaic panel mounting frame at the bottom of the photovoltaic panels. The power control box is equipped with a power system, a control and protection system, and an oxygen pump. The oxygen pump is connected to an oxygenation pipe extending into the scraper cloth water bag, and the bottom end of the oxygenation pipe is connected to an oxygenation head. Alternatively, an aerator can be installed at the bottom inside the scraper cloth water bag. The aerator is connected to a blower via an air pipe. The blower is also connected to the power system and the control and protection system, providing power to the blower and controlling its operation. The power supply system and control and protection system in the power control box are connected to the spray delivery pump and water pump, providing them with power and controlling their operation. The water pump draws water from the bottom of the aquaculture pond to the top of the sliding planting rack, enters the planting pipe, and then returns to the aquaculture pond through the return pipe. The water storage capacity of the planting pipe is no less than 1 / 10 of the aquaculture pond's water volume, forming a stable closed-loop water flow. The power supply system uses an existing, mature photovoltaic panel power generation system, purchased from the manufacturer. The power system is equipped with an AC mains connection, allowing AC mains power to be supplied when the battery pack power is insufficient.The floating aquaculture device includes a net cage float frame and a net cage. The net cage is suspended inside the net cage float frame. The net cage is an open-top, wide-mouth, narrow-bottom net cage, constructed from polyethylene mesh sewn into an inverted truncated pyramid structure. A semi-submersible aquaculture frame is placed inside the net cage. The semi-submersible aquaculture frame includes a shade frame and two parallel U-shaped pipes. The shade frame is a square frame formed by connecting four PVC pipes and three-dimensional tee joints. Each of the four corner tee joints of the square frame has a reducing straight connector below it for... The tops of the two vertical pipes of the two U-shaped tubes are covered, and the two U-shaped tubes support the shade frame to float on the water surface. Shading netting is fixedly covered on the left and right sides of the top of the shade frame. The area between the shading netting on both sides is used as a feeding port. The area of ​​the shading netting is larger than the plane of the left and right areas of the shade frame and hangs around the shade frame. A double-layered large-pore plastic netting for the breeding area of ​​climbing aquatic animals is installed between the two U-shaped tubes directly below the shade frame. A feeding platform is set on the double-layered large-pore plastic netting directly below the feeding port. The diameter of the U-shaped tubes is larger than the diameter of the other tubes connected to them. The sinking height of the semi-submersible breeding frame is adjusted by increasing or decreasing the water volume in the U-shaped tubes, which also ensures that the U-shaped tubes support the inner bottom sides of the net cage.

[0014] Step 2: Pre-planting and breeding debugging. Before officially starting planting and breeding, fill the breeding pool of the three-dimensional ecological planting and breeding device with water to the breeding water level, add concentrated Chlorella solution to the pool water to cultivate the breeding water quality, and start all equipment for no-load operation debugging. The floating breeding device is installed in the breeding pool and soaked for more than a week to allow algae to attach to the water, so as to avoid the seedlings being easily scratched when entering the pool.

[0015] Step 3: Stocking of Seedlings. After the aquaculture pond has been running for a week, the selected aquaculture species are disinfected and then placed into the pond. Based on the expected adult yield of 30-50 kg / m³ and a survival rate of 90%, the number of seedlings to be stocked is calculated. Seedlings are stocked into the floating aquaculture device according to a 2:1 ratio of climbing aquatic animals to benthic aquatic animals. First, the quarantined, disease-free, and uninjured benthic aquatic animal seedlings are gently placed into the net cage. After they swim to the bottom of the wide-mouthed, narrow-bottomed net cage, the climbing aquatic animal seedlings are then placed in. A shade cover is then added to prevent them from being exposed to light and allow them to concentrate on climbing on the semi-submersible aquaculture frame. After feeding the seedlings for a week, planting of dwarf hydroponic vegetables, fruits, or medicinal plants with complete and well-developed root systems is started in the planting cups of the planting tubes, wrapped with planting cotton. One or several bundles are planted in each planting cup, depending on the characteristics of the plant.

[0016] Step Four: Daily Management of Breeding and Aquaculture. Three days after stocking the seedlings in the aquaculture pond, begin feeding them at a rate of 5-8% of their body weight. Feed twice daily (morning and afternoon) or three times daily (morning, noon, and evening). Adjust the feeding amount regularly as the feed intake changes. For seedlings in floating aquaculture devices, begin feeding three days after stocking, strictly following the aquatic animals' habits, feeding at fixed times, quantities, and locations. Feed clump-shaped feed at 8-12% of the body weight of climbing aquatic animals. Regularly mix in an appropriate amount of astragalus polysaccharide to promote digestion and improve immunity. When feeding, open the feeding opening on the shade cover, place the clump-shaped feed on the feeding platform, and then close the feeding opening again. One hour after feeding, remove any uneaten feed from the feeding platform. The crushed material sinks to the bottom of the wide-mouthed, narrow-bottomed net cage, facilitating feeding for benthic aquatic animals. When feeding, gently press or move the floating aquaculture device. This serves two purposes: firstly, it provides feeding cues to the aquatic animals, facilitating concentrated feeding training; secondly, the shaking or movement promotes water exchange inside and outside the net cage, increasing dissolved oxygen levels and reducing sediment buildup. Diseased or dead seedlings are promptly treated or disposed of harmlessly. The growth of planted plants is regularly checked, and harmless pesticides are sprayed promptly to prevent pests and diseases. The water quality and meteorological sensors of the water quality and meteorological monitoring instrument are regularly maintained and calibrated monthly to ensure accurate measurement of key indicators such as air temperature, water temperature, dissolved oxygen, ammonia nitrogen, and nitrite. Every 10 days, EM bacterial solution and concentrated Chlorella solution are applied once each, and fresh water is added to the aquaculture level.

[0017] Step 5: Improve production records, regularly check equipment operation, promptly investigate and handle any equipment abnormalities, and back up relevant monitoring data as well as records of feeding and input usage.

[0018] Step Six: Harvesting, Screening, and Selling. Once the farmed aquatic animals have reached the harvest size, the semi-submersible farming frame is removed from the wide-mouth, narrow-bottom net cage. The opening of the wide-mouth, narrow-bottom net cage is tightened, and the aquatic animals inside the net cage are moved out of the floating frame. Then, the aquatic animals in the farming pond are harvested, screened, and classified for sale.

[0019] The key points for pre-planting and aquaculture debugging are as follows: First, continuously drive the pumping equipment using solar or wind power to draw water from the bottom of the aquaculture pond to the top of the sliding planting rack and into the PVC planting pipe network, then return the water from the bottom of the PVC planting pipe network to the aquaculture pond, ensuring that the PVC planting pipe network is leak-proof, the water storage volume is not less than 1 / 10 of the aquaculture pond's water volume, and a stable closed-loop water flow is formed; second, continuously drive the aeration equipment using solar or wind power to stably supply oxygen to the bottom of the aquaculture water body, ensuring that the dissolved oxygen level at the bottom of the water body at the expected stocking density is not less than 5 mg / L; third, through... The system utilizes solar or wind power storage to drive the spraying equipment at set times, ensuring that the spraying range basically covers the PVC planting pipe network area. It also uses solar or wind power storage to drive the heating equipment at set times, ensuring that the aquaculture water temperature reaches above the minimum tolerance temperature of the aquaculture organisms. Furthermore, the system uses solar or wind power storage to continuously drive meteorological and water quality monitoring equipment, which can accurately detect relevant meteorological and water quality indicators and automatically and intelligently control the pumping equipment to adjust the water flow, control the aeration equipment to adjust the air volume, activate the spraying equipment for cooling, and activate the heating equipment for heating and insulation based on preset indicator thresholds.

The bottom of the aquaculture pond rack forms an angle of 10° with the horizontal plane. The two long bottom sides are respectively pressed on two adjacent horizontal rectangular tubes of the "day"-shaped slide rail base to ensure that the "day"-shaped slide rail base does not shift when the sliding planting rack slides on the guide rails. Two structures composed of a cuboid and a right triangular prism are welded with square tubes. The triangular prism is located at the top of the cuboid. The planting tube mounting rack is welded between the two right triangular prisms to make the planting tube mounting rack inclined.

A photovoltaic panel mounting frame 3 is installed on the sliding planting frame 2, and a photovoltaic panel 5 is installed on the photovoltaic panel mounting frame 3. The photovoltaic panel 5 is connected to a power control box 4, which is installed inside the photovoltaic panel mounting frame 3 at the bottom of the photovoltaic panel 5. The power control box 4 is equipped with... The system includes a power supply system, a control and protection system, and an oxygenation pump. The oxygenation pump is connected to an oxygenation pipe 19 that extends into the water bag of the scraper cloth. The bottom end of the oxygenation pipe 19 is connected to an oxygenation head 20. The power supply system and control and protection system in the power control box 4 are connected to the spray delivery pump and the water pump, providing them with power and controlling their operation. The water pump 21 draws water from the bottom of the aquaculture pond to the top of the sliding planting rack and enters the planting pipe 8, and then returns it to the aquaculture pond through the return pipe 14. The water storage capacity of the planting pipe 8 is not less than 1 / 10 of the water volume of the aquaculture pond, forming a stable closed-loop water flow. The power supply system adopts an existing mature photovoltaic power generation system, purchased and used from the manufacturer.

Multiple planting tubes 8 and atomizing nozzles 10 are installed on the top surface of the planting tube mounting frame 11.During production, the rectangular track base in the shape of a Chinese character "Ri" can be fabricated first. It is formed by welding three horizontal rectangular tubes and two vertical short rectangular tubes into the shape of a Chinese character "Ri" on the same plane. Two equal-length angle irons are welded above the two vertical short rectangular tubes to serve as the guide rails for the sliding planting rack. One or two rectangular aquaculture pond racks welded with square tubes are placed on the three horizontal rectangular tubes of the rectangular track base in the shape of a Chinese character "Ri" and can be welded and fixed to the rectangular track base. The bottom of the aquaculture pond rack forms an angle of 10° with the horizontal plane, and the two long bottom edges are respectively pressed on two adjacent horizontal rectangular tubes of the rectangular track base in the shape of a Chinese character "Ri" to ensure that the rectangular track base in the shape of a Chinese character "Ri" does not shift when the sliding planting rack slides on the guide rails. Two structures composed of a cuboid and a right triangular prism are welded with square tubes. The triangular prism is located at the top of the cuboid, and a planting tube mounting rack is welded between the two right triangular prisms, making the planting tube mounting rack inclined. Steel concave pulleys are installed at the bottom of the cuboid and contact the guide rails. When pushed, it can just surround an aquaculture pond rack; when pushed to completely surround the aquaculture pond rack placed at the lower opening of the rectangular track base in the shape of a Chinese character "Ri", the long horizontal square tube at the bottom of its largest surface is completely superimposed above a long horizontal square tube on the surface of the aquaculture pond rack, and switch buckles are welded on the sides of the two long horizontal square tubes to fix the sliding planting rack without displacement; when pushed to completely surround the aquaculture pond rack placed at the upper opening of the rectangular track base in the shape of a Chinese character "Ri", its two shortest cubic tubes coincide with the two cubic tubes on the outer side of the aquaculture pond rack, and buckles are also welded on the sides of the four vertical and horizontal square tubes to fix the sliding planting rack without displacement. Multiple rows of installation limit columns are welded on the top surface of the planting tube mounting rack for installing and limiting the PVC planting tubes to form a single passage. Planting cup covers and planting cotton are placed at intervals on the upper tube surface of each PVC planting tube for cultivating plants; both ends of the PVC planting tube are blocked with PVC eccentric reducers with upward openings, and a PVC straight-through with a downward rotating cover sewage outlet needs to be installed at the drainage end of the PVC planting tube for cleaning the sediment in the PVC planting tube; each PVC planting tube is connected through a small-diameter PVC right-angle elbow connecting tube and a PVC pipe to form a single passage from top to bottom, and it is ensured that the water inlet of the uppermost PVC planting tube and the water outlet of the lowermost PVC planting tube are respectively placed at both ends of the aquaculture pond rack. Multiple rows of installation limit columns 13 for installing and limiting the planting tubes 8 are arranged on the top surface of the described planting tube mounting rack 11. A strengthening connecting rod 22 is connected between the two high vertical rods 23, and the connection position of the strengthening connecting rod 22 is higher than the height of the aquaculture pond rack 1 to avoid interference between the strengthening connecting rod 22 and the aquaculture pond rack 1 when the sliding planting rack 2 slides. One side of the described photovoltaic panel 5 is hinged and installed with a photovoltaic panel mounting rack 3, and a support rod is arranged at the bottom of the other side of the photovoltaic panel 5 to facilitate the adjustment of the angle of the photovoltaic panel 5.

[0046] Step 2: Pre-planting and breeding debugging. Before officially starting planting and breeding, fill the breeding pool of the three-dimensional ecological planting and breeding device with water to the breeding water level, add concentrated Chlorella solution to the pool water to cultivate the breeding water quality, and start all equipment for no-load operation debugging. The floating breeding device is installed and placed in the breeding pool inside the breeding pool frame, and soaked for more than a week to allow algae to attach in the water, so as to avoid the seedlings being easily scratched when entering.

[0047] Step 3: Stocking of Seedlings. After the aquaculture pond has been tested and run for one week, the selected aquaculture species are disinfected and then placed into the aquaculture pond. The number of seedlings to be stocked is calculated backward based on the expected marketable adult yield of 30-50 kg / m³ and a survival rate of 90%. The floating aquaculture device is based on a 2:1 ratio of climbing aquatic animals to benthic aquatic animals with complementary living habits. First, the quarantined, disease-free, and injury-free benthic aquatic animal seedlings are gently placed into the net cage. After they swim to the bottom of the wide-mouthed, narrow-bottomed net cage, the climbing aquatic animal seedlings are then placed in. A shade cover is then added to keep them in the semi-submersible aquaculture frame away from light. After feeding the seedlings for one week, planting of dwarf hydroponic vegetables, fruits, or medicinal plants with complete and well-developed root systems is started in the planting cups of planting tube 7, wrapped with planting cotton. One or several bundles are planted in each planting cup, depending on the characteristics of the plant.

[0048] Step Four: Daily Management of Breeding and Aquaculture. Three days after the seedlings are placed in the aquaculture pond, begin feeding them at a rate of 5-8% of their body weight. Feed twice daily (morning and afternoon) or three times daily (morning, noon, and evening). Adjust the feeding amount regularly as the feed intake changes. For floating aquaculture systems, begin feeding three days after stocking, strictly adhering to the aquatic animals' habits, feeding at fixed times, quantities, and locations. For climbing aquatic animals, feed them clump-shaped feed at 8-12% of their body weight. Regularly mix in an appropriate amount of astragalus polysaccharide to promote digestion and improve immunity. When feeding, open the feeding opening on the shade cover, place the clump-shaped feed on the feeding platform, and then close the feeding opening again. One hour after feeding, break up any leftover feed on the feeding platform and let it sink to the bottom of the wide-mouthed, narrow-bottomed net cage to facilitate feeding for benthic aquatic animals. When feeding, gently press or move the floating frame of the net cage. This serves two purposes: firstly, to provide feeding cues to the aquatic animals and facilitate their training to eat together; and secondly, to promote water exchange between the inside and outside of the net cage by shaking or moving it, thereby increasing dissolved oxygen levels and reducing sediment buildup. If any diseased or dead seedlings are found, treat them promptly or dispose of them harmlessly. Regularly check the growth of planted plants and spray them with pesticides that are harmless to the aquatic animals to prevent the occurrence of diseases and pests. Regularly measure the levels of dissolved oxygen, ammonia nitrogen, and nitrite in the water. Every 10 days, apply EM bacterial solution and concentrated Chlorella solution once each, and add fresh water to the aquaculture level.

[0049] Step 5: Improve production records, regularly check equipment operation, promptly investigate and handle any equipment abnormalities, and back up relevant monitoring data as well as records of feeding and input usage.

[0050] Step Six: Harvesting, Screening, and Selling. Once the farmed aquatic animals have reached the harvest size, the semi-submersible farming frame is removed from the wide-mouth, narrow-bottom net cage. The opening of the wide-mouth, narrow-bottom net cage is tightened, and the aquatic animals inside the net cage are moved out of the floating frame. Then, the aquatic animals in the farming pond are harvested, screened, and classified for sale. Example 2

[0051] The difference from Embodiment 1 is that: the water bag containing the knife-coated cloth is equipped with an electric heating tube and a temperature sensor. The electric heating tube and the temperature sensor are also connected to the power supply system and control and protection system in the power control box 4. The temperature sensor transmits temperature signals, and the control and protection system controls the electric heating tube to work according to the set program to heat the water in the water bag to the set temperature. Example 3

[0052] The difference from Embodiment 1 or Embodiment 2 is that: a water quality meteorological monitor 7 is installed on the sliding planting rack 2. The water quality meteorological monitor 7 is also connected to the power system and control and protection system in the power control box 4. The water quality meteorological monitor 7 transmits water quality meteorological information to the control and protection system in real time through the water quality sensor inserted into the aquaculture pond and the meteorological sensor fixed on the sliding planting rack 2. The control and protection system controls the operation of the oxygenation pump, the spray delivery pump 18 and the water pump 21 according to the set program. Example 4

[0053] The distinguishing feature from Embodiment 1, Embodiment 2 or Embodiment 3 is that: a wind turbine 6 is installed on the sliding planting rack 2, and the wind turbine 6 is connected to the power system in the power control box 4. The power system is equipped with an existing mature wind power generation system to charge the battery pack of the power system.

[0054] The floating aquaculture device described in the above embodiments includes a net cage float frame 26 and a net cage 27. The net cage 27 is suspended and installed inside the net cage float frame 26. The net cage 27 is an open-top, wide-mouth, narrow-bottom net cage, and the wide-mouth, narrow-bottom net cage is made of polyethylene mesh sewn into an inverted truncated pyramid structure. A semi-submersible aquaculture frame 28 is placed inside the net cage 27. The semi-submersible aquaculture frame 28 includes a shade frame 38 and two parallel U-shaped pipes 34. The shade frame 38 is a square frame formed by connecting four PVC pipes and three-dimensional tee joints 37. Each of the four corners of the square frame has a reducing straight connector 36 connected below the three-dimensional tee joints 37, which covers the top of the two vertical pipes of the two U-shaped pipes 34. The shade frame 38 is a semi-submersible aquaculture frame 28. Two parallel support pipes 41 connect the middle of the frame 38, dividing the shading frame 38 into three parts: left, middle, and right. The feeding port 42 is located in the middle area. Two pieces of shading netting 40 are fixedly covering the left and right areas of the shading frame 38, with their edges hanging down to the lower plane of the double-layer large-pore plastic netting 39. The shading netting 40 has a portion that can be flipped over to cover the middle area as a feeding port cover, forming a closable feeding port 42 with the two parallel support pipes 41. A double-layer large-pore plastic netting 39 for use as a climbing aquatic animal breeding area is installed between the two U-shaped pipes 34 directly below the shading frame 38. A feeding platform 43 is set on the double-layer large-pore plastic netting 39 directly below the feeding port 42. Water is injected into the U-shaped pipes, and the water level of the semi-submersible breeding frame 28 is adjusted by increasing or decreasing the amount of water in the U-shaped pipes until the semi-submersible breeding frame sinks to the plane of the upper large-pore plastic netting, ensuring that the U-shaped pipes 34 open the inner bottom sides of the net cage 27.

[0055] The cage floating frame 26 is made of two square upper frames 31 and lower frames 29 connected at the four corners by connecting pipes 30 and three-dimensional tee joints. The upper frames 31 and lower frames 29 are composed of hollow PVC pipe frames spliced ​​together.

[0056] The top opening of the net cage 27 is the same size as the inner cavity of the net cage float frame. It is secured to the top four corners of the float frame with cables. Its bottom area is 20-30% smaller than its top opening, and it hangs within the inner cavity of the float frame. A smooth shrimp-proof barrier membrane 33 is sewn to the outer edges of the top opening of the net body 32 of the net cage 27.

[0057] The outer periphery of the double-layer large-pore plastic mesh 39 is provided with a fastening connection frame. The fastening connection frame is formed by two connecting pipes 35 and two tight connecting pipes 44 connected to the vertical pipes of two U-shaped pipes 34. The vertical pipes of the same U-shaped pipe 34 are tightly connected with the tight connecting pipes 44, and the two vertical pipes on the same side of the two U-shaped pipes 34 are tightly connected with the connecting pipes 35. The double-layer large-pore plastic mesh 39 is wrapped and tightened around the connecting pipes 35 and tight connecting pipes 44.

[0058] The feeding platform 43 is formed by connecting four PVC pipes through right-angle elbows to form a rectangular feeding platform frame 45. The length of the feeding platform frame 45 is the same as or the same as the length and width of the semi-submersible breeding frame 28. Multiple fence pipes 46 are inserted and connected inside the rectangular frame. The fence pipes 46 can be inserted and removed to adjust the width of the fence according to the size of the breeding individuals, so that the breeding objects can enter and eat after feeding.

[0059] Application Cases

[0060] This renewable energy-driven three-dimensional farming technology has been applied on the rooftop of the Guangxi Aquatic Breeding Center in Jiangnan District, Nanning City, Guangxi Province. It utilizes a stainless steel square tube and angle iron welded together to form a 2.7-meter-long rectangular aquaculture tank frame (2.5×1.2×1.1 meters), a sliding planting frame (comprising a rectangular structure measuring 2.7×1.2×1.2 meters and a right-angled triangular structure with a height, width, and hypotenuse of 1.2 meters, 1.2 meters, and 1.7 meters respectively). The aquaculture tank frame, with its base at a 10° angle to the horizontal plane, is stacked on two adjacent stainless steel square tubes along the 2.7-meter-long rectangular structure and a right-angled triangular structure with a height, width, and hypotenuse of 1.7 meters. The sliding planting frame's rectangular structure has steel pulleys with a load capacity of up to 500 kg welded to its four corners, which are then attached to the 2.7-meter-long rectangular rails of the 2.7-meter-long rectangular structure and a right-angled triangular structure with a height, width, and hypotenuse of 1.7 meters. The right-angled triangular structure of the frame has square stainless steel columns welded to its inclined frame. Five PVC planting tubes, each 3 meters long and 200 mm in diameter, are installed, with nine 100 mm openings spaced 20 cm apart on each tube. These tubes hold planting cups and planting cotton. Both ends are fitted with 200 mm to 50 mm PVC eccentric reducers, and the tubes are connected to each other with 50 mm diameter PVC right-angle elbows to form a single, downward-facing pathway. The long, foldable bracket at the top of the right-angled triangular structure of the sliding planting frame is equipped with oxygenation, water pumping, spraying, and meteorological / water quality monitoring equipment. The spray nozzles are evenly distributed throughout the PVC planting tube network area. The air stones for the oxygenation equipment and the water quality probes for the meteorological / water quality monitoring equipment are suspended at the bottom of the aquaculture pond. The water pump is located at the lowest point of the inclined surface of the aquaculture pond, and the water pipe connects to the inlet of the PVC planting tube at the highest point of the sliding planting frame.A 2.5×1.2×1.1 meter (length×width×depth) knife-scraped cloth water bag is placed in the aquaculture pond frame and filled with water to a depth of 1 meter. The floating three-dimensional aquaculture assembly is installed inside the knife-scraped cloth water bag. The net cage float frame of the assembly is made of 30 mm diameter PVC pipe and connector components, with dimensions of 1.5×1×0.4 meters (length×width×height). The wide-mouth, narrow-bottom net cage is made of 9-mesh polyethylene netting, with an upper opening of 1.5×1 meter (length×width×height), a lower bottom of 1.2×1 meter, and a depth of 0.6 meters. The outer edge of the upper opening is sewn with a shrimp (frog) protection membrane. The semi-submersible aquaculture platform has dimensions of 1.2×1×0.4 meters (length×width×height) and is made of two 110 mm diameter PVC pipes and connector components (for making U-shaped pipes) and four 75 mm diameter PVC pipes connected together. The space formed by the 75 mm diameter PVC pipe is wrapped and tightened into two layers using a 5 cm aperture plastic mesh. The fence-style feeding frame is fixed in the center of the large-aperture plastic mesh on the upper layer of the semi-submersible aquaculture platform. It is formed by connecting four 25 mm diameter PVC pipes and right-angle elbows to form a rectangular frame. The length is equal to the width of the semi-submersible aquaculture platform, which is 1 meter. Holes are drilled on the inside of the PVC pipes on the two long sides of the frame, and thin plastic tubes are inserted to form a fence. The shade cover is 1.52 × 1 × 0.2 meters in length, width and height. It is made of four 50 mm diameter PVC pipes, a three-dimensional tee, a 50 mm diameter to 110 mm diameter reducer, and black shade netting. The black shade netting has an opening in the center of the frame, and the fence-style feeding frame is directly below it. After a week of water quality cultivation and unloaded operation testing, 150 quarantined, disease-free, and injury-free loach fry (approximately 5 cm in length) and 300 18-20 cm in length yellow eel fry were released into the net cages of the floating three-dimensional aquaculture system. Additionally, 30 15 cm long Suaeda salsa fry per square meter and 50 snail fry per square meter were released into the aquaculture ponds. Three days later, formal feeding began at a ratio of 5-8% of the fish's body weight, with feeding at 9:00 AM and 5:00 PM daily. Any sick or dead fish were immediately removed and disposed of harmlessly. One week after feeding the aquatic fry, planting of short-stemmed hydroponic vegetables and fruits with complete and well-developed root systems, such as arrowhead, was started within the planting cups on the PVC planting network, wrapped with planting cotton. Each planting cup contained one or several clusters of vegetables, depending on the characteristics of the plant. Based on changes in water quality indicators, EM bacterial stock solution and concentrated Chlorella solution were sprayed every 10 days, and fresh water was added to the aquaculture level of 0.9 meters. After nearly 10 months of aquaculture, samples were weighed from the renewable energy-driven three-dimensional ecological farming device. The average size of each eel was over 100 grams, the average size of each loach was over 30 grams, and the survival rate was over 80%. The average size of each Su's round-bellied fish was 1-1.8 jin, and the survival rate was 95%. The final actual output was 50 jin of eels, 8 jin of loach, 115 jin of Su's round-bellied fish, 8.6 jin of snails, and 31 jin of vegetables and fruits produced by the sliding planting rack.Throughout the entire breeding process, the solar-powered oxygenation, water pumping, spraying, and meteorological and water quality monitoring equipment operated normally. The dissolved oxygen in the breeding water was sufficient, and the ammonia nitrogen and nitrite levels in the water quality tests were maintained below 0.02 mg / L. No major diseases occurred in the farmed Su's round-bellied fish and the planted vegetables and fruits.
