Technical Field
[0001] This utility model belongs to the field of fish farming ponds, specifically relating to an ecological recirculating freshwater fish farming device. Background Technology
[0002] Freshwater fish farming equipment refers to aquaculture facilities required for freshwater fish farming, which aim to provide a suitable water environment, improve fish growth rate, reduce farming costs, and ensure stable water quality and fish health.
[0003] Traditional pond culture is the most common method of freshwater fish farming, typically suitable for small-scale fish farming. Ponds usually have a certain depth and area, and their construction cost is low, making them suitable for large-scale farming. However, fish often excrete large amounts of feces during the farming process, and excess waste accumulates at the bottom, affecting the cleanliness of the water. Turbid water often contains a large number of bacteria, leading to the spread of fish diseases and difficulties in water management. Furthermore, the depth and area of ponds make it difficult for workers to clean the sediment at the bottom. Using traditional cleaning tools can further mix the sediment with the water, affecting the clarity and hygiene of the water.
[0004] Therefore, to address the problem of the inconvenience of cleaning and recycling sediment at the bottom of existing freshwater fish ponds, an ecological circular freshwater fish farming device is developed. By adding automatic sediment cleaning, sediment recycling, water recirculation, and water flow control structures to the fish farming ponds, existing fish farming ponds can be equipped with the ability to automatically clean sediment at the bottom of the ponds. It also makes it easy for workers to recycle the cleaned sediment without affecting the water quality of the farming water. Utility Model Content
[0005] To overcome the problem of the difficulty in cleaning and recycling the sediment at the bottom of existing freshwater fish ponds.
[0006] The technical solution of this utility model is as follows: an ecological recirculating freshwater fish farming device, including a farming pond, a collection box, a planting net, a water-stop plate, a bottom cleaning block, a return spring, and a micro water pump. A symmetrically distributed front support is fixed to the front edge of the farming pond. A servo motor is fixed to one side of the front support. The left end of the servo motor's output passes through the front support and is fixed to a lead screw, the left end of which is adapted to the front support. A symmetrically distributed rear support is fixed to the rear edge of the farming pond. Guide rails are fixed between the rear supports. A series of guide rails are fixed to the upper sides of the bottom cleaning block. The front and rear connecting frames are symmetrically distributed. A first trough is opened through the right end of the aquaculture pond. A second trough is opened on the lower inner wall of the first trough. A third trough is opened through the upper edge of the aquaculture pond. A water-stop plate is installed in the third trough. A handle is fixed to the upper end of the water-stop plate. A return spring is installed on the outer wall of the handle. A limit plate is installed on the inner wall of the third trough. Through holes are symmetrically distributed at both ends of the limit plate. The inner wall of the through holes fits with the outer wall of the handle. The upper end of the return spring fits with the lower end of the limit plate. Aquatic plants are planted on the planting mesh.
[0007] As a preferred option, the inner wall of the aquaculture pond is equipped with a planting net panel, with notches at both the front and rear ends of the planting net panel.
[0008] Preferably, the front connecting frame has a threaded groove that matches the lead screw, and the rear connecting frame has a hole that fits the outer wall of the guide rail.
[0009] Preferably, the lower end of the waterstop plate is adapted to the second groove, and the outer wall of the waterstop plate is adapted to the first groove.
[0010] Preferably, the inner wall of the notch is adapted to the front and rear connecting frames, and the bottom cleaning block is triangular.
[0011] Preferably, a collection box is fixed to the right end of the aquaculture pond, and an opening and closing sealing plate is hinged to the lower inner wall of the collection box. A handle is fixed to the lower end of the opening and closing sealing plate.
[0012] Preferably, a miniature water pump is installed on the inner wall of the collection box, and a return pipe is installed on one end of the miniature water pump. The other end of the return pipe passes through the rear end of the collection box and is installed on the inner wall of the rear end of the aquaculture pond.
[0013] The beneficial effects of this utility model are:
[0014] 1. By pulling the handle, the waterstop plate is raised along the inner wall of the third tank to control the opening and closing of the waterstop plate, thereby controlling the flow of water between the breeding pond and the collection box. The return spring can drive the handle and the waterstop plate to fall and return to their original position after losing the power of the hand. Compared with the original opening and closing structure, it can effectively improve the convenience of the waterstop plate operation.
[0015] 2. The servo motor can drive the lead screw to rotate, thereby driving the front and rear supports to move the bottom cleaning block to scrape and clean the bottom sediment of the aquaculture pond in a reciprocating manner. It can also scrape the sediment at the bottom of the aquaculture pond into the collection box for automatic collection. Compared with the existing standing structure, it can improve the automation level of the cleaning structure and the stability during operation.
[0016] 3. By using a miniature water pump, the water in the collection tank can be transported back to the aquaculture pond through the return pipe.

[0025] An ecological recirculating freshwater fish farming system is an integrated device that combines aquaculture, wastewater treatment, and an ecological recycling system. It aims to improve farming efficiency while minimizing negative environmental impacts. This system typically integrates multiple technologies such as aquaculture, plant cultivation, and microbial treatment, enabling resource recycling, maintaining water quality, reducing external inputs, and lowering farming costs. The following are some key components and working principles of an ecological recirculating freshwater fish farming system:
[0026] 1. Aquaculture pond
[0027] Fish farming ponds are the primary environment for fish growth, and multiple ponds or tanks are typically set up, designed according to different farming scales. The water in the ponds is kept in circulation to effectively prevent water pollution and oxygen deficiency, ensuring the healthy growth of the fish.
[0028] 2. Biological filtration system
[0029] Biological filtration systems are a key component in removing harmful substances from water. Through the action of filter media and microorganisms, fish waste and leftover feed are transformed into harmless substances, maintaining water quality.
[0030] Common types of biological filters include trickling filters, sedimentation tanks, or biofilters.
[0031] 3. Water quality monitoring and regulation system
[0032] This includes real-time monitoring equipment for water quality parameters such as temperature, pH, oxygen content, and ammonia nitrogen concentration. If changes in water quality are detrimental to fish health, automated equipment can be used to adjust the water quality in a timely manner, ensuring a stable aquaculture environment.
[0033] 4. Water circulation system
[0034] Pumps, pipes, and other equipment are used to ensure the water circulates between different parts. The water circulation system can return filtered clean water to the aquaculture ponds, while simultaneously guiding organic waste through the filtration devices and plant roots for treatment.
[0035] 5. Planting System
[0036] In ecological circular aquaculture, hydroponics or wetland plants are often used. These plants absorb harmful substances (such as nitrogen and phosphorus) from the water through their root systems and convert them into nutrients needed by the plants. Common plants include water onions, water celery, and duckweed. This not only purifies the water but also provides additional economic benefits.
[0037] 6. Microbial degradation system
[0038] The system usually introduces some beneficial microorganisms, such as nitrifying bacteria, to help decompose organic matter in the water, reduce the concentration of ammonia nitrogen in the water, and maintain a healthy water cycle.
[0039] 7. Adjustable water temperature and lighting system
[0040] For certain freshwater fish species, temperature and light control are crucial. Suitable environmental conditions are maintained through heaters, cooling devices, and lighting regulation equipment to ensure fish growth.
[0041] 8. Intelligent monitoring and automatic control
[0042] To improve aquaculture efficiency and reduce manual labor, many modern ecological circular aquaculture devices are equipped with intelligent control systems that can monitor water quality, fish health, and other data in real time through sensors, and automatically adjust the aquaculture environment according to set parameters.
[0043] Working principle:
[0044] Water filtration and circulation: The water in the fish pond is filtered through a biological filter to remove waste and harmful substances, and then circulated back into the pond to maintain water quality.
[0045] Plant purification: The planting system absorbs elements such as nitrogen and phosphorus in the water, reducing eutrophication and purifying the water quality.
[0046] Waste utilization: Fish excrement, leftover feed and other organic matter provide nutrients for plants, while beneficial microorganisms further improve water quality by degrading these organic wastes.
[0047] Automated management: The system uses intelligent monitoring and control equipment to adjust water quality and environmental parameters in real time, ensuring the balance and stability of the aquaculture system.
[0048] advantage:
[0049] Water conservation: The circulating water system greatly reduces water waste and can effectively reduce water consumption.
[0050] Environmental protection: Reduced wastewater discharge and prevented water pollution.
[0051] High-efficiency production: Through integrated system management, it is possible to increase stocking density and fish growth rate. Sustainability: This ecosystem is a self-sustaining environment, reducing dependence on external resources and contributing to sustainable development.
[0052] Application scenarios:
[0053] Family farming: Small-scale ecological cycle systems are suitable for family or small-scale farming. Combined with hydroponics, family fish ponds, etc., they can raise fish and grow vegetables.
[0054] Commercial farming: Suitable for small and medium-sized farming enterprises, it can improve farming efficiency and reduce production costs.
[0055] Education and research: It provides an operational demonstration as a teaching and research tool in fields such as ecology and environmental protection.
[0056] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0057] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0058] Please see Figures 1-7 This utility model provides an embodiment: an ecological recirculating freshwater fish farming device, including a farming pond 1, a collection box 3, and a planting net 7, as well as a water-stop plate 5, a bottom cleaning block 4, a return spring 18, and a micro water pump 6. A front support 12 symmetrically distributed on both sides is fixed to the front edge of the farming pond 1. A servo motor 8 is fixed to one side of the front support 12. The left end of the output end of the servo motor 8 passes through the front support 12 and is fixed to a lead screw 2, the left end of which is adapted to the front support 12. A rear support 14 symmetrically distributed on both sides is fixed to the rear edge of the farming pond 1. Guide rails 15 are fixed between the rear supports 14. Symmetrically distributed guide rails 15 are fixed to the upper sides of the bottom cleaning block 4. The front connecting frame 16 and the rear connecting frame 17 of the fabric are connected together. A first groove 9 is opened through the right end of the aquaculture pond 1. A second groove 10 is opened on the lower inner wall of the first groove 9. A third groove 11 is opened through the upper edge of the aquaculture pond 1. A water-stop plate 5 is installed in the third groove 11. A handle 19 is fixed to the upper end of the water-stop plate 5. A return spring 18 is installed on the outer wall of the handle 19. A limit plate 20 is installed on the inner wall of the third groove 11. Through holes 21 are symmetrically distributed at both the upper and lower ends of the limit plate 20. The inner wall of the through holes 21 fits against the outer wall of the handle 19. The upper end of the return spring 18 fits against the lower end of the limit plate 20. Aquatic plants are planted on the planting net plate 7.
[0059] By pulling the handle 19, the waterstop plate 5 is raised along the inner wall of the third tank 11 to control the opening and closing of the waterstop plate 5, thereby controlling the flow of water between the breeding pond 1 and the collection box 3. The return spring 18 can drive the handle 19 and the waterstop plate 5 to fall and reset after losing hand power. The servo motor 8 can drive the lead screw 2 to rotate, thereby driving the front support 12 and the rear support 14 to drive the bottom cleaning block 4 to reciprocate to scrape and clean the bottom sediment of the breeding pond 1. It can also scrape the sediment at the bottom of the breeding pond 1 into the collection box 3 for automatic collection. The aquatic plants on the planting net plate 7 can biologically purify the water in the breeding pond 1. The micro water pump 6 can transport the water in the collection box 3 back to the breeding pond 1 through the return pipe 22, which makes it convenient for workers to collect and utilize the sediment at the bottom of the breeding pond 1.
[0060] Please see Figure 3 In this embodiment, a planting mesh plate 7 is installed on the inner wall of the aquaculture pond 1. The planting mesh plate 7 has notches 13 at both the front and rear ends. During use, the notches 13 can limit the front support 12 and the rear support 14 to improve their stability when moving back and forth along the bottom of the aquaculture pond 1. The inner wall of the notch 13 is adapted to the front connecting frame 16 and the rear connecting frame 17. The bottom cleaning block 4 is triangular. During use, the triangular bottom cleaning block 4 can fit tightly with the bottom of the aquaculture pond 1, so as to efficiently scrape and clean the sediment at the bottom of the aquaculture pond 1. The front connecting frame 16 has a screw groove adapted to the lead screw 2. The rear connecting frame 17 has a hole that fits with the outer wall of the guide rail 15. During use, the rear connecting frame 17 can assist the bottom cleaning block 4, which is driven by the front connecting frame 16 to move back and forth, to make stable displacement.
[0061] Please see Figures 2-3 In this embodiment, the lower end of the waterstop plate 5 is adapted to the second trough 10, and the outer wall of the waterstop plate 5 is adapted to the first trough 9. In use, the waterstop plate 5 with rubber pads on its edge can open and close the first trough 9 with high sealing performance, and cooperate with the second trough 10 to limit and fix the waterstop plate 5 to prevent the water pressure at the bottom of the aquaculture pond 1 from opening the closed waterstop plate 5.
[0062] Please see Figure 1 , Figure 2 , Figure 7 In this embodiment, a collection box 3 is fixedly connected to the right end of the aquaculture pond 1. An opening and closing sealing plate 23 is hinged to the lower inner wall of the collection box 3. A handle 24 is fixedly connected to the lower end of the opening and closing sealing plate 23. In use, the sealing plate 23 with its own rubber strip on the edge can ensure the sealing of the collection box 3 when it is closed. A micro water pump 6 is installed on the inner wall of the collection box 3. One end of the micro water pump 6 is equipped with a return pipe 22. The other end of the return pipe 22 passes through the rear end of the collection box 3 and is installed on the rear inner wall of the aquaculture pond 1. In use, the water in the collection box 3 can be transported back to the aquaculture pond 1 through the return pipe 22 by the micro water pump 6, which makes it convenient for workers to collect and utilize the sediment at the bottom of the aquaculture pond 1.
[0063] Before use, plant aquatic plants and other water-purifying plants on the planting net board 7, and put the aquaculture water and fresh water into the aquaculture pond 1 in sequence. The aquatic plants and other water will purify the aquaculture water to a certain extent.
[0064] When it is necessary to clean the sediment at the bottom of the breeding pond 1, first pull the handle 19 so that the handle 19 moves upward along the inner wall of the through hole 21 and drives the return spring 18 upward. The limit plate 20 squeezes the return spring 18, thereby causing the water stop plate 5 to rise and be stored in the third tank 11 and open the first tank 9, so that the breeding pond 1 and the collection box 3 are connected to each other.
[0065] Next, the servo motor 8 is started, which drives the lead screw 2 to rotate and drives the front connecting frame 16 and the rear connecting frame 17 to move the bottom cleaning block 4 back and forth along the bottom of the breeding pond 1 to scrape and clean the sediment at the bottom of the breeding pond 1 into the collection box 3 for storage.
[0066] Then, release the handle 19, and the return spring 18 pushes the stop plate 5 down into the second tank 10 for limiting and fixing. Then, the micro water pump 6 transports the aquaculture water in the collection box 3 back to the aquaculture pond 1 along the inner wall of the return pipe 22.
[0067] Finally, the worker pulls the handle 24 and rotates the opening and closing sealing plate 23, which is attached to the inner wall of the lower end of the collection box 3, to open it. The scraped sediment from the aquaculture pond 1 will fall downwards, and then the worker can collect and utilize it.
[0068] Through the above steps, pulling the handle 19 can drive the waterstop plate 5 to rise along the inner wall of the third tank 11 to control the opening and closing of the waterstop plate 5, thereby controlling the flow of water between the breeding pond 1 and the collection box 3. The return spring 18 can drive the handle 19 and the waterstop plate 5, which have lost their hand-held power, to descend and reset. The servo motor 8 can drive the lead screw 2 to drive the front support 12 and the rear support 14 to drive the bottom cleaning block 4 to reciprocate to scrape and clean the bottom sediment of the breeding pond 1. It can also scrape the sediment at the bottom of the breeding pond 1 into the collection box 3 for automatic collection, solving the problem that the sediment at the bottom of existing freshwater fish ponds is not easy to clean and recycle.
[0069] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
