Description

Technical Field

[0001] This utility model relates to the field of ecological aquaculture, and in particular to a partitioned ecological circular aquaculture box. Background Technology

[0002] In recent years, with the promotion of green agriculture and the concept of sustainable development, ecological circular aquaculture has gradually replaced traditional single-species aquaculture and become a key direction in agricultural production. Among them, aquaculture devices that realize the symbiotic model of "aquatic plants + aquatic animals" in a single container can achieve self-purification of the aquaculture environment and resource reuse through the material cycle between plants and fish, thereby improving the aquaculture efficiency per unit area and environmental friendliness.

[0003] In existing technologies, numerous ecological aquaculture systems have been proposed. For example, Chinese patent CN108592697A discloses a recirculating aquaculture system for fish and vegetables. This system uses a circulating pump to transport aquaculture water to a plant trough and then back to the fish farming area to achieve a preliminary ecological cycle. However, such systems typically suffer from the following drawbacks: First, the zoning function is incomplete, with insufficient physical separation between the fish and plant areas, allowing suspended matter generated by fish activities to easily enter the plant root zone, affecting plant absorption efficiency. Second, the circulation system design is simplistic, often relying solely on unidirectional water flow, which easily leads to water stratification or eutrophication problems.

[0004] The technical problem this application seeks to solve is: how to provide an ecologically recirculating aquaculture tank with clearly defined zones, bidirectional circulation, and light regulation functions, so as to simultaneously ensure the healthy growth of fish and plants and improve the overall aquaculture efficiency and system stability. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a partitioned ecological cycle breeding box.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a partitioned ecological recirculating aquaculture box, comprising an aquaculture box body, a box cover at the upper end of the aquaculture box body, connecting pipes installed on the surface of the box cover, a rotating knob installed on the outer wall of the box cover, a circulation pump A and a circulation pump B installed on the outer wall of the aquaculture box body, connecting channels A and B installed at the upper and lower ends of the circulation pump A, a movable plate installed inside the aquaculture box body, a fixed support plate installed on the inner wall of the aquaculture box body, a barrier net A and a barrier net B installed at the bottom of the movable plate, a filter screen installed at one end of the connecting channels A and B, a movable rack installed on the inner wall of the box cover, and a rubber baffle plate and gears connected between the movable racks.

[0007] As a further description of the above technical solution:

[0008] The bottom of the main body of the breeding box is fixedly connected to a support block. A limiting groove is opened on the surface of the main body of the breeding box.

The limiting groove and the limiting post are inserted into each other. There are four limiting posts. The box cover is movably connected to the upper end of the main body of the breeding box through the limiting posts.

[0009] As a further description of the above technical solution:

[0010] The connecting pipe is integrally connected to the upper surface of the box cover. The connecting pipe is connected to the interior of the main body of the breeding box. There are several connecting pipes. The fixed support plate is fixedly connected to the inner wall of the main body of the breeding box. The movable plate is movably connected to the surface of the fixed support plate. The main body of the breeding box is divided into two by the movable plate. Aquatic plants are raised above the movable plate, and fish are raised below the movable plate.

[0011] As a further description of the above technical solution:

[0012] The circulating pump A and circulating pump B are fixedly installed on the outer wall of the main body of the breeding tank. The circulating pump A transports water from top to bottom, and the circulating pump B transports water from bottom to top. The connecting channel A is fixedly connected between the main body of the breeding tank and the circulating pump A. The connecting channel A is installed at the upper end of the circulating pump A. The connecting channel B is fixedly connected between the circulating pump A and the main body of the breeding tank. The connecting channel B is installed at the lower end of the circulating pump A.

[0013] As a further description of the above technical solution:

[0014] The barrier net A and barrier net B are fixedly installed at the bottom of the breeding box body. The mesh count of barrier net A is greater than that of barrier net B. The barrier net A and barrier net B divide the bottom of the breeding box body into three parts. The filter net is fixedly installed at the connection between the breeding box body and the connecting channel B and the connecting channel A.

[0015] As a further description of the above technical solution:

[0017] This utility model has the following beneficial effects:

[0018] In this invention, a dual-pump system, with circulation pump A and circulation pump B, respectively establishes "top-to-bottom" and "bottom-to-top" water circulation channels, creating a closed-loop flow path within the water body and preventing localized water siltation or insufficient oxygen content. Combined with the partitioned structure of the filter screen, connecting channels, and barrier nets A / B, it effectively prevents bottom sediments from circulating to the upper layers with the water flow, maintaining the purity of the water quality in the plant root zone and fish activity zone, thereby achieving the sustainable and stable operation of the symbiotic ecological chain of aquatic plants and fish.

[0019] The interior of the aquaculture tank is divided into two sections by internal movable panels and fixed support panels, forming a vertical ecological layout of "planting on top and aquaculture on the bottom." This allows the plants to fully absorb nutrients such as nitrogen and phosphorus from fish excrement, thus playing a natural role in water purification. Simultaneously, barrier nets A and B, based on their different mesh sizes, create multi-stage sedimentation filtration zones, further promoting the classification and sedimentation of particulate matter in the water, ensuring clear and stable water, and contributing to improved ecological carrying capacity and aquaculture efficiency per unit volume.

[0020] This device achieves dynamic adjustment of light intensity within the enclosure by incorporating a movable rack, rubber sunblock, gear, and knob linkage system inside the transparent cover. When sunlight is intense, users can rotate the knob to drive the gears, which in turn slide the sunblock, adjusting the light penetration in different areas. This reduces water temperature fluctuations and excessive evaporation, effectively improving plant photosynthetic efficiency while preventing strong light stress on fish, thus providing a more precise environmental control method for stable system operation.

[0029] Reference Figure 1-4 One embodiment provided by this utility model:

[0030] Example 1:

[0031] A partitioned ecological recirculating aquaculture box includes an aquaculture box body 1, a box cover 2 at the upper end of the aquaculture box body 1, a connecting pipe 3 installed on the surface of the box cover 2, a rotary knob 5 installed on the outer wall of the box cover 2, a circulation pump A6 and a circulation pump B19 installed on the outer wall of the aquaculture box body 1, a connecting channel A7 and a connecting channel B8 installed at the upper and lower ends of the circulation pump A6, a movable plate 11 installed inside the aquaculture box body 1, a fixed support plate 12 installed on the inner wall of the aquaculture box body 1, a barrier net A13 and a barrier net B14 installed at the bottom of the movable plate 11, a filter screen 15 installed at one end of the connecting channel A7 and the connecting channel B8, a movable rack 16 installed on the inner wall of the box cover 2, and a rubber baffle plate 17 and a gear 18 connected between the movable racks 16.

[0032] Working principle and usage: This partitioned ecological recirculating aquaculture tank achieves water circulation through the cooperation of circulation pumps A and B. Water flows from top to bottom through circulation pump A, exits through connecting channel A, and returns to the main body of the aquaculture tank through connecting channel B, thus realizing water recycling. Simultaneously, by setting up a movable panel, the main body of the aquaculture tank is divided into upper and lower areas; the upper area is for cultivating aquatic plants, and the lower area is for raising fish, forming an ecological cycle.

[0033] Aquatic plants produce oxygen through photosynthesis, providing ample oxygen for the fish, while the fish's excrement serves as nutrients for the aquatic plants, achieving an ecological cycle in aquaculture. Furthermore, by setting up barrier nets A and B, fish of different sizes can be separated, preventing fighting. And by incorporating a movable rack, rubber sunblock, and gears, the position of the rubber sunblock can be adjusted by rotating a knob, thereby controlling the light intensity inside the enclosure and providing suitable lighting conditions for the aquatic plants.

[0034] Example 2:

[0035] The connecting pipe 3 is integrally connected to the upper surface of the box cover 2. The connecting pipe 3 is connected to the interior of the breeding box body 1. There are several connecting pipes 3. The fixed support plate 12 is fixedly connected to the inner wall of the breeding box body 1. The movable plate 11 is movably connected to the surface of the fixed support plate 12. The breeding box body 1 is divided into two by the movable plate 11. Aquatic plants are raised above the movable plate 11, and fish are raised below the movable plate 11.

[0036] Barrier nets A13 and B14 are fixedly installed at the bottom of the breeding box body 1. The mesh count of barrier net A13 is greater than that of barrier net B14. Barrier nets A13 and B14 divide the bottom of the breeding box body 1 into three parts. Filter net 15 is fixedly installed at the connection between the breeding box body 1 and the connecting channel B8 and connecting channel A7.

[0037] The improvement of the implementation scheme of this embodiment compared with the prior art is that: by setting the movable plate 11, the main body of the breeding tank 1 is divided into an "upper aquatic plant area" and a "lower fish breeding area" in the vertical direction, forming a stable water-biological circulation channel.

[0038] Two layers of barrier nets, A13 and B14, with different mesh sizes are installed at the bottom of the breeding tank, dividing the bottom area into three settling layers. This effectively constructs a step-by-step filtration channel for particulate matter, consisting of coarse, medium, and fine particles, effectively intercepting suspended matter such as fish metabolites, uneaten feed, and algae flocs.

[0039] By installing filter screens 15 at the connection points between the connecting channels A7 and B8 and the aquaculture tank, secondary physical filtration of the incoming / returning water is achieved. This structure, combined with the design of the bidirectional circulation pump and connecting channels, allows for purification before and after the pumped water flows through, preventing the accumulation of particulate matter in the circulation system from clogging the pipes. It also reduces mechanical wear on the pump body, thereby ensuring the circulation stability and long-term operation of the entire system.

[0040] Example 3:

[0041] A support block 4 is fixedly connected to the bottom of the main body 1 of the breeding box. A limiting groove 10 is opened on the surface of the main body 1 of the breeding box. A limiting post 9 is integrally connected to the bottom of the box cover 2. The size of the limiting groove 10 is adapted to the size of the limiting post 9. The limiting groove 10 and the limiting post 9 are inserted into each other. There are four limiting posts 9. The box cover 2 is movably connected to the upper end of the main body 1 of the breeding box through the limiting posts 9.

[0042] Circulation pump A6 and circulation pump B19 are fixedly installed on the outer wall of the breeding tank body 1. Circulation pump A6 transports water from top to bottom, and circulation pump B19 transports water from bottom to top. Connecting channel A7 is fixedly connected between the breeding tank body 1 and circulation pump A6. Connecting channel A7 is installed at the upper end of circulation pump A6. Connecting channel B8 is fixedly connected between circulation pump A6 and breeding tank body 1. Connecting channel B8 is installed at the lower end of circulation pump A6.

[0043] The improvement of the implementation scheme of this embodiment compared with the prior art is that: this embodiment introduces a plug-in structure of limiting post 9 and limiting groove 10 between the main body 1 of the breeding box and the box cover 2, and realizes the rapid alignment and stable connection of the box cover in the vertical direction through the four-point limiting positioning method.

[0044] The system employs a dual-pump layout with circulation pumps A6 and B19 to establish independent vertical water flow paths, unlike existing systems that typically use a single circulation pump. This bidirectional replenishment design not only creates "ecological convection" between the plant and fish layers, enhancing the balance of dissolved oxygen and nutrient distribution, but also effectively breaks down vertical stratification caused by temperature differences, thereby increasing the overall activity of the water body.

[0045] Connecting channels A7 and B8 are respectively positioned at the upper and lower ends of the circulating pump A6, serving as bridging nodes between the pump body and the aquaculture tank. This structure ensures structural consistency in the water flow direction, effectively reduces the impact of backflow pressure fluctuations on the pump chamber, extends the pump body's service life, and prevents problems such as backflow, leakage, and localized water accumulation caused by misaligned interfaces in traditional layouts. This further guarantees the system's long-term circulation stability and low failure rate.

[0046] Example 4:

[0047] The movable rack 16 is slidably connected to the inner wall of the box cover 2. The rubber sunblock 17 is fixedly connected between the movable rack 16. The box cover 2 is transparent, while the rubber sunblock 17 is opaque. There are several rubber sunblocks 17. The gear 18 is meshed between the movable rack 16. The rotary knob 5 is rotatably connected to the middle of the outer wall of the box cover 2. The gear 18 is fixedly connected to the rotary knob 5.

[0048] The improvement of the implementation scheme of this embodiment compared with the prior art is as follows: This embodiment sets a movable rack 16 and an opaque rubber sunblock 17 inside the transparent box cover 2, and drives them by the linkage system of gear 18 and rotary knob 5, so that the sunblock 17 can slide along the rack to realize the dynamic adjustment of the light area. This solution allows users to accurately control the light distribution and duration according to the photoperiod requirements of different crops, the intensity of external light and the sensitivity of fish to light, effectively improving the system's adaptability to multi-species co-culture scenarios.

[0049] The light-blocking adjustment operation can be completed by a purely mechanical structure that drives the gear 18 to move the movable rack 16 by rotating the knob 5, without relying on an electronic control system.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
