Description

Technical Field

[0001] This invention belongs to the field of intelligent aquaculture technology, specifically relating to an intelligent aquaculture system that separates fish from fertilizer. Background Technology

[0002] Aquatic products are an important part of the human diet and one of the main sources of animal protein. With global population growth and rising living standards, the demand for aquatic products is increasing. However, the rapid development of aquaculture, particularly the shift from extensive to intensive farming, has also led to a series of ecological pollution problems, such as uneaten feed, animal excrement, dissolved nutrients, dissolved organic matter, and biological remains.

[0003] To address the ecological pollution problems caused by aquaculture, some agricultural technology companies have successfully developed a fish-plant symbiotic aquaculture program. This program utilizes fish waste, organic matter, dissolved nutrients, and leftover feed from fish farming in plant cultivation. The plants absorb these substances from aquaculture, thereby purifying the aquaculture environment and promoting plant growth. This program is particularly suitable for areas with abundant water resources but poor soil.

[0004] Existing aquaponics farming solutions, such as the Chinese patent document with patent number 201921974244.4, disclose intelligent aquaponics farming equipment, including a frame, a fish tank, and a storage cabinet connected sequentially from top to bottom. The frame has a display screen at the top and is divided into several layers. Each layer has a plant grow light at the top and a planting trough at the bottom. The storage cabinet contains a filter connected to the fish tank. One end of the filter is connected to the fish tank, and the other end has a water pump. The water pump is connected to the planting trough via a water pipe, and the planting trough is connected to the fish tank. The fish tank, display screen, planting trough, plant grow light, filter, and water pump are all electrically connected to a PLC. This system allows the water used for fish farming to be filtered, nitrified, and then pumped into the planting trough to become "nutrient solution" for the plants, eliminating the need for additional fertilization. The clean water, absorbed and purified by the plant roots and then sterilized, flows back to the fish tank for the fish to consume. The current aquaculture system uses a single-loop circulating water system for both aquaculture and plant cultivation. However, in practice, aquaculture requires continuous water flow over long periods, while plant cultivation only requires intermittent watering. Therefore, this system is not suitable for practical applications. Furthermore, even after purification and sterilization, the water used for plant cultivation is re-entered into the fish tank, still potentially polluting the aquaculture water. The cost of purification and sterilization is also high, while the volume of water returned from plant cultivation is very limited, making its return to the fish tank after purification and sterilization unnecessary. Therefore, a more reasonable intelligent aquaculture system is needed to address these issues. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides an intelligent aquaculture system for separating fish and fertilizer.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A smart aquaculture system for separating fish and fertilizer includes an aquaculture pond, a plant cultivation module, a water circulation module for circulating water in the aquaculture pond, a water supply device for irrigating the plant cultivation module, and a controller for controlling the operation of circuit components within the smart aquaculture system. The water circulation module is located behind the aquaculture pond, and the plant cultivation module is installed above it. The controller is electrically connected to the water circulation module and the water supply device and controls their operation. The water circulation module includes a fermentation chamber, a filtration chamber, and a purification chamber arranged sequentially. The filtration chamber contains filter media for water filtration and purification and is connected to the aquaculture pond. A one-way valve is provided between the fermentation chamber and the filtration chamber, allowing fluid to flow only from the filtration chamber to the fermentation chamber. The filtration chamber is connected to the purification chamber, and a first water pump is installed in the purification chamber. The outlet of the first water pump is connected to the aquaculture pond via a water pipe.

[0008] In this invention, the water circulation route in the aquaculture process is as follows: under the action of the first water pump, the water source of the aquaculture pond enters the filter chamber. After the water source is filtered and purified by the filter media in the filter chamber, it enters the clean water chamber. Then, the first water pump flows the water source in the clean water chamber back to the aquaculture pond.

[0009] In this invention, the water supply device includes a second water pump installed in the fermentation chamber. The outlet of the second water pump is connected to the top of the plant planting module through a water pipe. The bottom of the plant planting module is provided with a return channel, and a return port is provided between the return channel and the fermentation chamber.

[0010] In this invention, the water circulation route of the plant planting process is as follows: under the action of the second water pump, the plant water formed by the fermentation of fish manure in the fermentation chamber is extracted and supplied to the top of the plant planting module through the water pipe. The plant water flows downward under the action of gravity and passes through the plant planting module from top to bottom to water the plants. The remaining water flows into the return channel and flows back to the return port through the return channel, and then returns to the fermentation chamber through the return port.

[0011] In this invention, the filtration chamber is provided in two parts, including a primary filtration chamber and a secondary filtration chamber. The fermentation chamber is located on the side of the primary filtration chamber away from the secondary filtration chamber. The primary filtration chamber has an inlet for water from the aquaculture pond to enter for filtration and purification. The purified water chamber has an outlet for water from the purified water chamber to enter the aquaculture pond.

[0012] In this invention, the primary filtration chamber is provided with a filter residue area for filter residue accumulation. The filter residue area is located in front of the fermentation chamber, and the water inlet is located directly opposite the filter residue area.

[0013] In this invention, the bottom of the fermentation chamber is provided with an inclined panel that is inclined to the bottom of the primary filtration chamber, and the one-way valve is installed on the inclined panel, which is positioned on the side facing the filter residue area.

[0014] In this invention, a first partition plate is provided between the primary filtration chamber and the secondary filtration chamber, and the first partition plate has a first water passage hole for connecting the primary filtration chamber and the secondary filtration chamber; a second partition plate is provided between the secondary filtration chamber and the purified water chamber, and the second partition plate has a second water passage hole for connecting the secondary filtration chamber and the purified water chamber, and the position height of the first water passage hole is higher than the position height of the second water passage hole.

[0015] In this invention, the bottom of the plant planting module is provided with a semi-circular guide plate for forming a return channel and a return port, and the top of the first partition plate and the second partition plate are provided with a semi-circular recess that matches the semi-circular guide plate. The semi-circular guide plate is supported by the semi-circular recess.

[0016] In this invention, the bottom of the plant planting module is completely isolated from the primary filtration chamber, the secondary filtration chamber, and the water purification chamber.

[0017] The beneficial effects of this invention are as follows: by setting up a filter chamber and a fermentation chamber in the water circulation module, and setting a one-way valve between the filter chamber and the fermentation chamber, the filter residue in the filter chamber can enter the fermentation chamber through the one-way valve, while the fermentation products in the fermentation chamber will not flow into the filter chamber. This separates the water circulation for aquaculture from the water circulation for plant cultivation, ensuring that both can operate reasonably. The water used for plant cultivation will not pollute the water used for aquaculture, thus ensuring the water quality of the water used for aquaculture. The water used for plant cultivation can also utilize the substances produced by aquaculture, which are fermented and decomposed in the fermentation chamber to become fertilizer for plant cultivation, thereby achieving the separation of fish and fertilizer.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] Example:

[0028] like Figures 1 to 8As shown, this embodiment discloses an intelligent aquaculture system for separating fish and fertilizer, including an aquaculture pond 1 for aquaculture, a plant cultivation module 2 for plant cultivation, a water circulation module 3 for circulating the water source of the aquaculture pond 1, a water supply device 4 for providing water for irrigation of the plant cultivation module 2, and a controller 5 for controlling the operation of the circuit devices within the intelligent aquaculture system. The water circulation module 3 is located at the rear of the aquaculture pond 1, and the plant cultivation module 2 is installed above the water circulation module 3. The controller 5 is electrically connected to the water circulation module 3 and the water supply device 4, and controls the operation of the water circulation module 3 and the water supply device 4. The water circulation module 3 includes a fermentation chamber 31 and a filtration chamber arranged sequentially. The system comprises a filter chamber 32 and a water purification chamber 33. The filter chamber 32 is equipped with filter media for water filtration and purification, and is connected to the aquaculture pond 1. A one-way valve 6 is provided between the fermentation chamber 31 and the filter chamber 32, allowing fluid to flow only from the filter chamber 32 to the fermentation chamber 31. The filter chamber 32 is connected to the water purification chamber 33, and a first water pump 7 is provided in the water purification chamber 33. The outlet of the first water pump 7 is connected to the aquaculture pond 1 through a water pipe. The water circulation route in the aquaculture process is as follows: under the action of the first water pump 7, the water source of the aquaculture pond 1 enters the filter chamber 32. After being filtered and purified by the filter media in the filter chamber 32, the water source enters the water purification chamber 33, and then the water source in the water purification chamber 33 flows back to the aquaculture pond 1 through the first water pump 7. The water supply device 4 includes a second water pump installed in the fermentation chamber 31. The outlet of the second water pump is connected to the top of the plant planting module 2 through a water pipe. The bottom of the plant planting module 2 is provided with a return channel 21, and a return port 22 is provided between the return channel 21 and the fermentation chamber 31. The water circulation route of the plant planting process is as follows: under the action of the second water pump, the plant water formed by the fermentation of fish manure in the fermentation chamber 31 is drawn and supplied to the top of the plant planting module 2 through the water pipe. The plant water flows downward under the action of gravity, passing through the plant planting module 2 from top to bottom to water the plants. The remaining water flows into the return channel 21 and returns to the return port 22 through the return channel 21, and then returns to the fermentation chamber 31 through the return port 22. When the second water pump draws water from the plants in fermentation chamber 31, the water pressure in fermentation chamber 31 decreases, while the water pressure in filter chamber 32 becomes higher. Consequently, one-way valve 6 automatically opens, allowing water from filter chamber 32 to enter fermentation chamber 31. Simultaneously, accumulated fish feces and feed residue from filter chamber 32 also enter fermentation chamber 31, effectively removing these wastes. When the water pressure in filter chamber 32 returns to the same level as that in fermentation chamber 31, one-way valve 6 automatically closes.

[0029] In a preferred embodiment, several filter chambers 32 can be provided to form a multi-stage filtration and purification structure. In this embodiment, there are two filter chambers 32, including a primary filter chamber 321 and a secondary filter chamber 322. The fermentation chamber 31 is located on the side of the primary filter chamber 321 away from the secondary filter chamber 322. The primary filter chamber 321 has an inlet 8 for water from the aquaculture pond 1 to enter the filtration and purification process, and the purified water chamber 33 has an outlet 9 for water from the purified water chamber 33 to enter the aquaculture pond 1. The primary filtration chamber 321 contains a filter cake section 323 for the accumulation of fish feces and feed residue. This filter cake section 323 is located in front of the fermentation chamber 31, and the water inlet 8 is directly opposite it. The bottom of the fermentation chamber 31 has an inclined panel 311 that slopes towards the bottom of the primary filtration chamber 321. The one-way valve 6 is mounted on the inclined panel 311, which faces the filter cake section 323, allowing water to enter the aquaculture pond 1. During circulating filtration, the filter media enters the primary filtration chamber 321 through the inlet 8. Under the filtration effect of the filter media, fish feces and feed residues accumulate in the filter residue zone 323, preventing these fish feces and feed residues from re-entering the aquaculture pond 1. When the second water pump is working, under the action of the inclined plate 311, the water flow is drawn into the fermentation chamber 31 at an angle, which has a wider range of filter residue absorption and can absorb most of the filter residue into the fermentation chamber 31, thereby improving the filter residue removal rate of the filter residue zone 323.

[0030] In this embodiment, a first partition plate 324 is provided between the primary filtration chamber 321 and the secondary filtration chamber 322. The first partition plate 324 has a first water passage hole 325 for connecting the primary filtration chamber 321 and the secondary filtration chamber 322. A second partition plate 326 is provided between the secondary filtration chamber 322 and the purified water chamber 33. The second partition plate 326 has a second water passage hole 327 for connecting the secondary filtration chamber 322 and the purified water chamber 33. The position height of the first water passage hole 325 is higher than the position height of the second water passage hole 327, so that the water in the primary filtration chamber 321 passes through the secondary filtration chamber 322 and the purified water chamber 33 from high to low, thereby ensuring that the circulating water is fully filtered.

[0031] In this embodiment, the bottom of the plant planting module 2 is provided with a semi-circular guide plate 23 for forming a return channel 21 and a return port 22. The top of the first partition plate 324 and the second partition plate 326 is provided with a semi-circular recess 328 that is adapted to the semi-circular guide plate 23. The semi-circular guide plate 23 is supported by the semi-circular recess 328.

[0032] In this embodiment, the bottom of the plant planting module 2 is completely isolated from the primary filter chamber 321, the secondary filter chamber 322 and the water purification chamber 33. This prevents the plant roots in the plant planting module 2 from growing into the primary filter chamber 321, the secondary filter chamber 322 and the water purification chamber 33, thus preventing the plant roots from polluting the circulating water of the aquaculture pond 1.

[0033] In this embodiment, the intelligent aquaculture system also includes a solar lamp 10, which illuminates the plant planting module 2 to promote photosynthesis in the plants.

[0034] In this embodiment, the back of the water circulation module 3 is also provided with a light strip 14, with the light-emitting surface of the light strip 14 facing the aquaculture pond 1. This allows the light emitted by the light strip 14 to pass through the water circulation module 3 and illuminate the aquaculture pond 1, giving the aquaculture pond 1 a lighting effect and improving the aesthetics of the intelligent aquaculture system. Specifically, the back of the water circulation module 3 is provided with a slot structure 11 and a clip 12 that are interlocked. The clip 12 has a slot 13 for installing the light strip 14. The light strip 14 is fixed in the slot 13, and the clip 12 is connected to the slot structure 11 by interlocking, realizing a convenient installation structure between the light strip 14 and the water circulation module 3. When installing the light strip 14, it is only necessary to insert the clip 12 into the slot structure 11; when disassembling the light strip 14, it is only necessary to pull the clip 12 out of the slot structure 11, making disassembly and assembly very convenient.

[0035] In this embodiment, both the first water pump 7 and the second water pump are connected to the controller 5 via a circuit. The first water pump 7 is kept powered on for an extended period to maintain continuous water circulation in the aquaculture pond 1, ensuring the water quality of the pond 1. The second water pump is controlled by a timer switch. The controller 5 contains a timer that controls the timer switch of the second water pump. An automatic feeder is also installed on the aquaculture pond 1. The automatic feeder switch is controlled by a timer. The automatic feeder can be based on the structure of the automatic feeder in the applicant's previously developed automatic aquaculture system, specifically referring to the Chinese patent document with patent number "201910827837.6" and patent title "An Automatic Koi Carp Aquaculture System".

[0036] In this embodiment, the aquaculture pond 1 is also equipped with a pH sensor to detect the pH value of the water in the aquaculture pond 1. The top of the water circulation module 3 has an opening for adding materials to the water circulation module 3, and the opening is sealed by a cover plate 34. An acid additive and an alkaline additive are provided on the cover plate 34, both of which pass through the cover plate 34 and are connected to the primary filter chamber 321. The pH value of the water in the aquaculture pond 1 is preferably 7-8.5. When the pH sensor detects that the pH value of the water in the aquaculture pond 1 is less than 7, the alkaline additive adds alkaline substances to the primary filter chamber 321 to raise the pH value; when the pH sensor detects that the pH value of the water in the aquaculture pond 1 is greater than 8.5, the acid additive adds acidic substances to the primary filter chamber 321 to lower the pH value. This achieves the acid-base regulation of the water in the aquaculture pond 1. Specifically, lactic acid bacteria or organic acids can be added to the acid additive. For example, if lactic acid bacteria are added to the acid additive, when the pH value of aquaculture pond 1 needs to be lowered, the acid additive adds lactic acid bacteria to the primary filter chamber 321. The lactic acid bacteria ferment in the primary filter chamber 321 to produce lactic acid, thereby lowering the pH value of aquaculture pond 1. When organic acids are added to the acid additive, the organic acids can directly lower the pH value of aquaculture pond 1. Quicklime or sodium bicarbonate can be added to the alkaline additive, which can adjust the pH value of aquaculture pond 1 while also sterilizing and disinfecting the water. In this embodiment, the acid-base regulating substances are added to the primary filter chamber 321, and after filtration by the filter media in the primary filter chamber 321 and secondary filter chamber 322, they enter the aquaculture pond 1, thereby ensuring the water quality of aquaculture pond 1. The acid-base regulation method is more reasonable, allowing the aquatic organisms in aquaculture pond 1 to better adapt to the regulated environment.

[0037] In this embodiment, the aquaculture pond 1 is also equipped with an ammonium ion sensor, which is used to detect the ammonium ion concentration in the water of the aquaculture pond 1. The cover plate 34 is equipped with a culture container for cultivating beneficial bacteria. The injection end of the culture container passes through the cover plate 34 and connects to the water purification chamber 33. The ammonium ion concentration in aquaculture needs to be controlled below 1.5 mg / L. When the ammonium ion concentration in aquaculture exceeds 1.5 mg / L, an appropriate amount of beneficial bacteria is added to the water purification chamber 33 through the culture container, and the beneficial bacteria convert and decompose the ammonium ions.

[0038] In this embodiment, a dissolved oxygen sensor is installed in the water purification tank 33, and an aerator is also installed in the aquaculture pond 1. The dissolved oxygen sensor is used to measure the dissolved oxygen content of the water in the water purification tank 33. Since the water in the aquaculture pond 1 enters the aquaculture pond 1 through the water purification tank 33, by measuring the dissolved oxygen content of the water in the water purification tank 33, the highest dissolved oxygen content in the aquaculture pond 1 when the aerator is turned off can be determined. Therefore, by installing the dissolved oxygen sensor in the water purification tank 33 and measuring the dissolved oxygen content of the water in the water purification tank 33, the dissolved oxygen content of the water in the aquaculture pond 1 can be determined more accurately, thereby controlling the aerator's air volume. In aquaculture, the dissolved oxygen content of the water is most comfortable for aquatic growth when controlled within the range of 5-14 mg / L. Therefore, when the dissolved oxygen sensor detects that the dissolved oxygen content in the water is below 5 mg / L, the air volume of the aerator is increased, thereby increasing the dissolved oxygen content in aquaculture pond 1; when the dissolved oxygen sensor detects that the dissolved oxygen content in the water is above 14 mg / L, the air volume of the aerator is decreased, thereby reducing the dissolved oxygen content in aquaculture pond 1.

[0039] In this embodiment, the water purification tank 33 is also equipped with a conductivity sensor. The conductivity sensor measures the conductivity of the water in the water purification tank 33. Based on the linear relationship between conductivity and salinity, the conductivity is converted to salinity. In aquaculture, the salinity of the water is controlled below 1 g / L. When the conductivity sensor detects that the salinity is higher than 1 g / L, the aquaculture pond 1 is controlled to perform a water exchange. Additionally, conductivity can also be converted to TDS content. Based on the linear relationship between conductivity and TDS content, the TDS content can be calculated. In aquaculture, the TDS content is controlled within the range of 200-300 mg / L. A sodium chloride container is provided on the cover plate 34, and the injection end of the sodium chloride container passes through the cover plate 34 and connects to the primary filter chamber 321. When the TDS content is below 200 mg / L, an appropriate amount of sodium chloride is injected into the primary filtration chamber 321 through the sodium chloride container to increase the conductivity of the water, thereby increasing the TDS content. When the TDS content is above 300 mg / L, an appropriate amount of beneficial bacteria is added into the water purification chamber 33 through the culture container, and the beneficial bacteria convert and decompose the ions.

[0040] In this embodiment, the aquaculture pond 1 is also equipped with a nitrate ion sensor, and beneficial algae are cultivated within the pond, along with lighting lamps to promote photosynthesis. During aquaculture, the nitrate content is controlled below 20 mg / L. When the nitrate content exceeds 20 mg / L, the light intensity of the lighting lamps is increased to accelerate photosynthesis and promote the consumption of nitrates by the algae.

[0041] In this embodiment, the fermentation chamber 31 is equipped with ammonium ion sensors, phosphate ion sensors, and potassium ion sensors for detecting ammonium ions, phosphate ions, and potassium ions in the water, respectively. The top of the plant cultivation module 2 is equipped with an ammonium sulfate adder, a potassium dihydrogen phosphate adder, a potassium chloride adder, and a water adder. Ammonium sulfate solution, potassium dihydrogen phosphate solution, potassium chloride solution, and water are respectively added to the ammonium sulfate adder, potassium dihydrogen phosphate adder, potassium chloride adder, and water adder. During plant cultivation, the concentration of ammonium ions is required to be controlled between 5-15 mg / L. When the ammonium ion sensor detects an ammonium ion concentration below 5 mg / L, the ammonium sulfate adder is controlled to add ammonium sulfate solution to the plant cultivation module 2, thereby supplementing ammonia nitrogen for plant growth. When the ammonium ion sensor detects an ammonium ion concentration above 15 mg / L, the water adder is controlled to add water to the plant cultivation module 2, thereby reducing the ammonium ion concentration. The concentration of phosphate ions should be controlled between 2-10 mg / L. When the phosphate ion sensor detects a concentration below 2 mg / L, the potassium dihydrogen phosphate adder is controlled to add potassium dihydrogen phosphate solution to plant planting module 2 to supplement phosphate for plant growth. When the phosphate ion sensor detects a concentration above 10 mg / L, the water adder is controlled to add water to plant planting module 2 to reduce the phosphate ion concentration. The concentration of potassium ions should be controlled between 30-50 mg / L. When the potassium ion sensor detects a concentration below 30 mg / L, the potassium ion adder is controlled to add potassium chloride solution to plant planting module 2 to supplement potassium for plant growth. When the potassium ion sensor detects a concentration above 50 mg / L, the water adder is controlled to add water to plant planting module 2 to reduce the potassium ion concentration.

[0042] In this embodiment, the top of the plant planting module 2 is provided with a diversion module 24. The diversion module 24 includes a diversion cavity 241 and a diversion structure 242 located within the diversion cavity 241. The diversion structure 242 protrudes upward from the bottom of the diversion cavity 241. The diversion structure 242 has a diversion port 243 communicating with the planting module. The diversion structure 242 has a diversion groove 244 that allows water to enter the diversion port 243 through the diversion structure 242. Through this structure, the diversion module 24 can distribute the water in the diversion cavity 241 to each diversion port 243, preventing all water entering the diversion module 24 from flowing out of the diversion port 243 near the inlet 8, while the diversion ports 243 far from the inlet 8 have no water. In this embodiment, the diversion module 24 can ensure that each planting cavity 25 receives water irrigation, and the amount of irrigation water received by the planting cavity 25 corresponding to each diversion port 243 is uniform. The top of the diversion chamber 241 is also provided with a sealing plate 245, which has a feeding port for adding plant nutrients. The feeding port also allows observation of the water flow inside the diversion chamber 241. Ammonium sulfate, potassium dihydrogen phosphate, potassium chloride, and clean water additives are all connected to the diversion module 24, injecting the corresponding conditioning solutions into the diversion chamber 241 of the diversion module 24.

[0043] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by essentially the same means is within the protection scope of the present invention.
