Technical Field

[0001] This invention belongs to the field of ecological farming technology, specifically relating to an aquaponics farming system and its control method. Background Technology

[0002] A vegetable growing machine is a product combining science and technology with natural ecology. It uses advanced modern technology to simulate the ideal natural environment for vegetable growth, thus achieving the goal of vegetable cultivation and representing a form of facility agriculture. It also simplifies many steps of traditional planting methods, meeting the needs of some modern urban dwellers who want to eat vegetables they have grown themselves. Currently, vegetable growing machines include a base, support frame, and several planting trays. The base contains a nutrient solution container. The machine also includes a water system for delivering the nutrient solution needed for vegetable growth, a temperature control system for regulating the nutrient solution, a lighting system for providing the light source needed for the vegetables, and a nutrient solution concentration control system. Existing technologies typically cultivate vegetables by adding nutrient solution alone, which is relatively simple in function and suffers from limitations in nutrient supply and the inability to meet the needs of vegetable growth. Summary of the Invention

[0003] The purpose of this invention is to provide an aquaponics farming device that enables the simultaneous cultivation of vegetables and fish farming in one device, and can provide rich and balanced nutrients for the vegetables to grow by utilizing the waste generated by the farmed fish.

[0004] The following technical solutions are used to achieve the above objectives.

[0005] The first aspect of the present invention provides an aquaponics farming and aquaculture cycle device, the aquaponics farming and aquaculture cycle device comprising: a box body, a partition, a conveying device, and a planting pool; the partition is horizontally inserted into the box body to divide the space inside the box body into a first cavity and a second cavity, and the first cavity is located above the second cavity; the planting pool is disposed on the box body; the partition has a drainage hole connecting the first cavity and the second cavity;

[0006] The conveying device is connected to the second cavity and the planting pool respectively, and the conveying device is used to transport the mud and water in the second cavity to the planting pool. The planting pool is connected to the box body through a mud return pipe.

[0007] In some embodiments, the planting pool and the sludge return pipe are connected by a filter cylinder, the filter cylinder having a filter outlet, the filter cylinder being fitted with a filter box, the filter box being connected to the first cavity via a return pipe, and the end of the sludge return pipe away from the filter cylinder being connected to the second cavity.

[0008] In some embodiments, a filter screen is provided at the outlet of the water filter tank connected to the return pipe.

[0009] In some embodiments, the filter tank is also connected to a backwash water supply pipe, the outlet of the backwash water supply pipe faces the filter screen, and the backwash water supply pipe is equipped with a switch valve for controlling the opening and closing of the pipe.

[0010] The filter tank is connected to the sludge return pipe via a connecting pipe, and a one-way valve is installed at the connecting pipe to control the direction of water flow from the filter tank to the sludge return pipe.

[0011] In some embodiments, the sludge return pipe is connected to a pressure relief storage device via a pressure relief pipe, and a sludge valve is provided on the sludge return pipe at a position corresponding to the pressure relief pipe and the second cavity.

[0012] In some embodiments, a water level detection device for detecting the water level height inside the cavity is provided in the first cavity.

[0013] In some embodiments, the conveying device includes a conveying pipe, a spiral feeding rod, and a driving device; the conveying pipe is connected to the second cavity and the planting pool respectively, the spiral feeding rod is rotatably disposed in the conveying pipe, and the driving device is connected to the spiral feeding rod and drives the spiral feeding rod to rotate.

[0014] In some embodiments, the partition located within the first cavity is provided with a layer of pebbles covering the seepage holes.

[0015] In some embodiments, the planting pool is provided with a planting plate, the planting plate has a plurality of planting holes, and the planting pool is provided with a fixing cylinder corresponding to the position of the planting holes, the peripheral wall of the fixing cylinder has a plurality of evenly distributed mesh holes.

[0016] In a second aspect, the present invention provides a control method for an aquaponics farming system, based on the aquaponics farming system described above, comprising the following steps:

[0017] Fish are raised in the first chamber of the tank, and the sediment produced by the fish falls into the second chamber through the seepage holes of the partition.

[0018] The control conveying device transports the mud and water accumulated in the second cavity to the planting pool to supply nutrients to the plants planted in the planting pool.

[0019] After the plants have absorbed the nutrients from the mud and water, the mud and water return to the second cavity through the mud return pipe.

[0020] The technical solution provided by this invention has the following advantages and effects:

[0021] This aquaponics farming system uses a partition within the tank to create a first and a second chamber. The first chamber is used for fish farming, and the fish excrement and feed residue fall into the second chamber through seepage holes in the partition for storage. Once sufficient sludge accumulates in the second chamber, it is transported to the planting pond via a conveyor to provide nutrients for the plants. Because the sludge contains abundant organic and inorganic matter necessary for plant growth, it provides rich and balanced nutrients to meet the needs of vegetables and other plants. Meanwhile, the vegetables in the planting pond absorb nutrients and purify the sludge-water mixture. The purified sludge-water mixture flows back into the tank through a sludge return pipe, thus achieving sludge-water recycling. Therefore, this aquaponics farming system can simultaneously cultivate vegetables and raise fish in one device, and utilize the waste generated by the fish to provide rich and balanced nutrients for the vegetables, achieving an ecological and environmentally friendly goal.

[0026] To facilitate understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0027] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0028] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0029] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0030] This invention provides an aquaponics farming and aquaculture recycling device 100, such as... Figure 1 As shown, the aquaponics farming and aquaculture system 100 includes: a box 1, a partition 2, a conveying device 3, and a planting pool 4; the partition 2 is horizontally inserted into the box 1 to divide the space inside the box 1 into a first cavity 11 and a second cavity 12, and the first cavity 11 is located above the second cavity 12; the planting pool 4 is disposed on the box 1, and the partition 2 has a drainage hole 21 connecting the first cavity 11 and the second cavity 12; wherein, the first cavity 11 forms a fish farming space for raising fish, and the excrement and feed residue generated during fish farming fall into the bottom of the second cavity 12 through the drainage hole 21 of the partition 2 under its own gravity to form sludge.

[0031] The conveying device 3 is connected to the second cavity 12 and the planting pool 4, respectively. The conveying device 3 is used to transport the mud and water in the second cavity 12 to the planting pool 4. The planting pool 4 is connected to the box 1 through the mud return pipe 5. The planting pool 4 is used to grow vegetables and other plants. When the excrement and feed residue generated during fish farming fall to the bottom of the second cavity 12 and accumulate for a period of time, the conveying device 3 is activated. The conveying device 3 transports the mixture of sludge and water in the second cavity 12 to the planting pool 4. Since the sludge contains abundant organic and inorganic matter required by plants, the sludge transported to the planting pool 4 by the conveying device 3 can provide rich and balanced nutrients to meet the needs of plant growth.

[0032] In summary, the aquaponics farming and recycling device 100 forms a first cavity 11 and a second cavity 12 by setting a partition 2 inside the box 1. The first cavity 11 is used for raising fish. The excrement and feed residue produced by the fish fall into the second cavity 12 through the seepage holes 21 of the partition 2 for storage. After the second cavity 12 accumulates enough sludge, it is transported to the planting pond 4 through the conveying device 3 to supply nutrients to the plants. Since the sludge contains a lot of organic and inorganic matter required by plants, it can provide rich and balanced nutrients to meet the needs of plant growth when transported to the planting pond 4 as nutrients for vegetables and other plants. The vegetables planted in the planting pond 4 can purify the mud water while absorbing nutrients. The purified mud water flows back into the box 1 through the mud return pipe 5, thereby realizing the recycling of mud water. Therefore, the aquaponics farming and aquaculture recycling device 100 can realize the simultaneous cultivation of vegetables and fish farming in one device, and can provide rich and balanced nutrients for the cultivated vegetables through the waste generated by the fish farming to meet the growth needs and can be recycled, thus achieving the goal of ecological and environmental protection.

[0033] In some embodiments, such as Figure 1 As shown, the planting pool 4 and the sludge return pipe 5 are connected by a filter cylinder 51. The filter cylinder 51 has filter holes, and a filter box 52 is fitted onto the filter cylinder 51. The filter box 52 is connected to the first cavity 11 via a return pipe 53. The end of the sludge return pipe 5 away from the filter cylinder 51 is connected to the second cavity 12. Understandably, after the vegetables planted in the planting pool 4 absorb nutrients and purify the muddy water, the purified muddy water passes through the filter cylinder 51. The filter cylinder 51 separates the purified water from the sludge. The water is filtered out from the filter holes of the filter cylinder 51 into the filter box 52 and then returns to the first cavity 11 via the return pipe 53 for recycling. The purified sludge cannot flow out from the filter holes of the filter cylinder 51 and returns to the second cavity 12 via the filter cylinder 51 and the sludge return pipe 5 for recycling. Therefore, by using the filter cylinder 51, filter box 52, return pipe 53 and sludge return pipe 5 together, the purified water and sludge can be separated and returned to the first chamber 11 and the second chamber 12, effectively preventing the sludge from affecting the water quality in the first chamber 11.

[0034] In some embodiments, such as Figure 1 As shown, a filter screen 54 is provided at the outlet of the water filter tank 52 connected to the return pipe 53. When water is filtered out from the filter hole of the water filter cylinder 51 into the water filter tank 52, it is filtered again by the filter screen 54 before entering the first chamber 11 for recycling. This effectively avoids the presence of silt or large debris when the purified water flows into the first chamber 11, which would affect the water quality in the first chamber 11.

[0035] In some embodiments, such as Figure 1As shown, the filter tank 52 is also connected to a backwash water supply pipe 55, the outlet of which faces the filter screen 54. A switch valve 59 is installed on the backwash water supply pipe 55 to control the opening and closing of the pipe. The filter tank 52 is connected to the sludge return pipe 5 via a connecting pipe, and a one-way valve 56 is installed at the connecting pipe to control the direction of water flow from the filter tank 52 to the sludge return pipe 5. When the water level in the tank 1 is too low, the switch valve 59 is opened, and water is added to the filter tank 52 through the backwash water supply pipe 55. Simultaneously, the impact of the water flow washes away impurities from the surface of the filter screen 54. Due to the instantaneous increase in pressure inside the filter tank 52, the water carrying impurities flows through the one-way valve 56 into the sludge return pipe 5 and out to the second chamber 12 to replenish the water level in the tank 1.

[0036] In some embodiments, such as Figure 1 As shown, the sludge return pipe 5 is connected to the pressure relief storage device 58 via the pressure relief pipe 57. A sludge valve 6 is provided on the sludge return pipe 5 at the position between the pressure relief pipe 57 and the second cavity 12. Understandably, when the backflushing water supply pipe 55 adds water to the filter tank 52, the pressure in the filter tank 52 increases instantaneously, and the water flow into the sludge return pipe 5 suddenly increases. Therefore, it is necessary to temporarily store the water flowing into the sludge return pipe 5 so that it can flow smoothly into the tank 1. Specifically, the water that enters the sludge return pipe 5 for a short time is temporarily stored through the pressure relief pipe 57 and the pressure relief storage device 58. After the water is added, it flows back into the sludge return pipe 5 under the action of gravity.

[0037] In some embodiments, such as Figure 1 As shown, a water level detection device 7 is provided in the first cavity 11 to detect the water level in the cavity. The water level detection device 7 can be a water level sensor or other device that can sense the water level. The water level detection device 7 can detect the water level in the first cavity 11. When the water level is too low, the backwash water supply pipe 55 is activated to add water to the filter tank 52 to replenish the water in the first cavity 11.

[0038] In some embodiments, such as Figure 1 As shown, the conveying device 3 includes a conveying pipe 31, a spiral feeding rod 32, and a driving device 33. The conveying pipe 31 connects the second cavity 12 and the planting pool 4. The spiral feeding rod 32 is rotatably disposed within the conveying pipe 31. The driving device 33 is connected to the spiral feeding rod 32 and drives the spiral feeding rod 32 to rotate. Specifically, the driving device 33 includes a drive motor and a reducer connected to the drive motor. The reducer is connected to the spiral feeding rod 32. By driving the spiral feeding rod 32 to rotate through the driving device 33, the sludge in the second cavity 12 can be smoothly lifted into the planting pool 4.

[0039] In some embodiments, such as Figure 1As shown, a pebble layer 22 is provided on the partition 2 located in the first cavity 11, covering the infiltration holes 21. It should be noted that multiple infiltration holes 21 are evenly arranged on the partition 2. Fish excrement and feed residue fall onto the pebble layer 22 through the gaps between the pebble layers 22 and then fall into the second cavity 12 through the infiltration holes 21 to form a sludge layer.

[0040] In some embodiments, such as Figure 1 As shown, a planting plate 41 is provided on the planting pool body 4. The planting plate 41 has multiple planting holes. A fixing cylinder 42 is provided on the planting pool body 4 corresponding to the position of the planting holes. The peripheral wall of the fixing cylinder 42 has multiple evenly distributed mesh holes. The planting holes of the planting plate 41 are used to fix the planted vegetables. Each planting plate 41 can plant multiple vegetables. Each vegetable is fixed by a planting hole and the fixing cylinder 42 corresponding to that planting hole. Specifically, the vegetable roots pass through the planting hole and fall into the fixing cylinder 42 of the planting pool body 4. The fixing cylinder 42 is used to fix the vegetable roots, which can prevent the vegetable roots from becoming tangled and affecting the flow of silt. The mesh holes on the fixing cylinder 42 can facilitate the absorption of nutrients by the vegetable roots.

[0041] In some embodiments, the box 1 is a square box or a circular box, etc., without particular limitation; specifically, in this embodiment, the box 1 is a square box. The shape of the planting pool 4 is adapted to the structure of the box 1 so that the planting pool 4 can be adapted to be installed on the box 1. Specifically, in this embodiment, the partition 2 is inserted horizontally and in a sealed manner inside the box 1 to divide the space inside the box 1 into the first cavity 11 and the second cavity 12. Furthermore, in a specific embodiment, another partition 2 can also be inserted into the box 1 corresponding to the position of the first cavity 11 to divide the first cavity 11 into a third cavity and a fourth cavity, wherein the third cavity is located between the fourth cavity and the first cavity 11, and the third cavity is used for raising fish. The planting plate 41 is erected above the fourth cavity to form the planting pool 4. Both partitions 2 have through holes for the conveying device 3 to pass through, so that the sludge in the second cavity 12 can be transported to the planting pool 4 in the fourth cavity for plant use.

[0042] The present invention also provides a control method for an aquaponics farming and aquaculture cycle device 100, which, based on the aquaponics farming and aquaculture cycle device 100 described above, includes the following steps:

[0043] Fish are raised in the first cavity 11 of the container 1, and the sediment produced by the fish falls into the second cavity 12 through the seepage hole 21 of the partition 2.

[0044] The control conveying device 3 transports the mud and water accumulated in the second cavity 12 to the planting pool 4 to supply nutrients to the plants planted in the planting pool 4.

[0045] After the plants have absorbed the nutrients from the mud and water, the mud and water return to the second cavity 12 through the mud return pipe 5.

[0046] The control method of this aquaponics farming and recycling device 100 allows the sludge produced by fish farming in the first chamber 11 to be discharged into the second chamber 12. The sludge from the second chamber 12 is then transported to the planting pond 4 via a conveying device 3 to supply nutrients to the plants. Since the sludge contains abundant organic and inorganic matter, when transported to the planting pond 4 as nutrients for the vegetables, it provides rich and balanced nutrients to meet the needs of plant growth. The plants in the planting pond 4 absorb nutrients while purifying the mud and water. The purified mud and water then flows back to the tank 1 through a mud return pipe 5, thus achieving the recycling of the mud and water. Therefore, the control method of this aquaponics farming and recycling device 100 enables simultaneous fish farming and vegetable cultivation within a single device, and allows the waste generated by fish farming to provide rich and balanced nutrients for the grown vegetables, meeting their growth needs and enabling recycling, thus achieving the goal of ecological and environmental protection.

[0047] The above embodiments are not an exhaustive list based on the present invention, and there may be many other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
