Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture and marine products, and more specifically, refers to a single-plane aquaculture structure for transforming an existing fish pond to provide a multi-level plane structure with a multi-level plane aquaculture structure. Background Art

[0002] Traditional aquaculture uses a single-plane structure aquaculture pond to raise benthic and sand-sinking fish, shrimp, crab, snail, shellfish, insects and other aquatic animals. Benthic aquatic animals are easily affected by the low sand content or even clay content of the pond bottom, and the poor water quality of fresh and seawater sources, including slight differences in water temperature, water depth, salinity, dissolved oxygen content and bacterial count, which can easily cause slow growth, growth stagnation, sporadic deaths, seasonal and occasional large-scale deaths of benthic aquatic animals, resulting in limited production of benthic aquatic animals.

[0003] In order to prevent the occurrence of mass deaths of benthic aquatic animals, it is necessary to avoid using polluted water sources or other pond water where benthic aquatic animals have died. Therefore, the original single-plane breeding structure must frequently replace a large amount of pond water to maintain the quality of the water in the breeding pond, resulting in low utilization rate of a large amount of pond water and high maintenance costs. In addition, in order to improve the aging breeding pond bottom environment, it will be necessary to refill sand and soil to provide a good breeding environment for benthic aquatic animals. Refilling sand and soil will also increase breeding costs. Utility Model Content

[0004] The utility model aims to transform the single plane breeding structure of the existing fish pond and provide a breeding mode structure with a multi-level plane structure.

[0005] The utility model has a multi-layer plane aquaculture structure comprising: a culture pond, an air pump; the four sides and the bottom of the culture pond are sealed by plastic cloth or concrete, and the top of the culture pond is covered or not covered with transparent plastic cloth to form a fully enclosed culture space or a semi-enclosed culture space with nothing on top; the culture space inside the culture pond is provided with a multi-layer plane structure, a submerged motor, and piping; the multi-layer plane structure comprises a plurality of vertically spaced air-permeable load plates; the air pump is connected to the piping, and the piping is located below the air-permeable load plate to provide oxygen and create a vertical water flow. When the oxygen floats up and contacts the air-permeable load plate, a thin plane of air temporary retention is formed below the air-permeable load plate; the submerged motor is used to create a horizontal water flow and to circulate clean water between the culture space and the outside.

[0006] Furthermore, a plurality of vertically spaced air-permeable load-bearing plates are locked on a height-adjustable assembly stand, and the piping is arranged under the bottom air-permeable load-bearing plate.

[0007] Furthermore, the breathable load-bearing plate is square or polygonal, and the integrated tripod is a long rod including a cylinder or a circular tube or a polygonal cross-section.

[0008] Furthermore, the air holes of the air-permeable load plate are polygonal holes.

[0009] Furthermore, the pipe is a circular pipe or a long rod with a polygonal cross section and has a vent hole.

[0010] Furthermore, the breathable load plate is a box-type breathable load plate, and the piping is arranged below the bottom layer of the box-type breathable load plate.

[0011] Furthermore, the box-type breathable load-bearing plate is a circular or polygonal box-type breathable load-bearing plate.

[0012] Furthermore, a plurality of vertically spaced breathable load plates are suspended in series by ropes in the culture pond, and the lowest breathable load plate is fixed to the bottom of the pond by rope nets or weights; and piping is arranged below the lowest breathable load plate.

[0013] Furthermore, the air pump is arranged on the shore away from the water surface according to the water level depth of the breeding pond.

[0014] Furthermore, the pipes are also arranged on the sides or below of the culture pond.

[0015] After adopting the above technical solution, the utility model has at least the following technical effects:

[0016] 1. The air pump is connected to the pipe to provide oxygen. The oxygen at the bottom layer uses the upward buoyancy of the gas in the water to supply oxygen to the collective vertical arrangement and different horizontal layers at the same time. When the air floats up and contacts the breathable load plate, a layer of air temporary retention thin plane will be formed under the breathable load plate, increasing the contact area and time between the air and the water body. Because there is one more layer of breathable load plate, there will be one more layer of air temporary retention thin plane, so that the contact area and time between the air and the water body will grow exponentially with the number of layers of the separation structure, which can increase the dissolved oxygen content in the water and reduce the volatilization utilization rate of the traditional single plane structure. At the same time, the submerged motor creates a horizontal water flow, and the air pump pumps up the air to create a vertical water flow, which is combined into a dead-angle water flow, so that feed, semi-submerged feed, algae bait, and organic debris can be diffused and cultivated with the water flow; and the excrement is extracted by the submerged motor and treated by the external water purification facility to remove ammonia nitrogen, and then returned to the breeding pond for circulating water breeding.

[0017] 2. The utility model can form a diffusion effect of water convection and oxygen exchange to achieve a stable dissolved oxygen content. In this way, it can not only increase the breeding space, but also ensure the concentration of dissolved oxygen in the water. Through this breeding method, the yield of benthic aquatic animals can be increased, and at the same time, the recycling of water-saving breeding can be achieved.

[0018] 3. Traditional aquaculture for aquatic animals living in the bottom and in the sand is based on a single plane structure, which limits the yield. The advantage of the multi-level plane structure is that it can create multiple planes for aquaculture, that is, it can harvest multiple yields. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model is a multi-layered aquaculture structure, which will utilize the multi-layered plane structure to transform the existing fish pond farming model, including: a farming pond, an air pump 24; the surroundings and the bottom of the farming pond are sealed by plastic sheeting or concrete, and the top of the farming pond is covered or not covered with a transparent plastic sheet 20 to form a fully enclosed farming space or a semi-enclosed farming space with nothing on top; the farming space inside the farming pond is provided with a multi-layered plane structure, a submerged motor, and piping 25; the multi-layered plane structure includes a plurality of vertically spaced breathable load plates 22; the air pump 24 is connected to the piping 25, and the piping 25 is located below the breathable load plate 22 to provide oxygen and create a vertical water flow. When the oxygen floats up and contacts the breathable load plate 22, a thin plane of air temporary retention will be formed below the breathable load plate 22; the submerged motor is used to create a horizontal water flow and to circulate clean water between the farming space and the outside. Please refer to Figure 1 As shown, it is an embodiment that the top of the breeding pond is covered with a transparent plastic sheet 20.

[0024] Multiple vertically spaced air load boards 22 are locked to an adjustable height assembly stand 21. The assembly stand 21 is used to support a single air load board 22. Multiple air load boards 22 can be used to form a multi-level plane structure (please refer to Figure 2 More specifically, the breathable load-bearing plate 22 is square or polygonal, and the integrated tripod 21 is a long rod including a cylinder or a circular tube or a polygonal cross-section.

[0025] In another embodiment, box-type breathable load plates can be directly stacked, and the pipes are arranged under the bottom box-type breathable load plates; more specifically, the box-type breathable load plates include circular or polygonal box-type breathable load plates. Alternatively, multiple vertically spaced breathable load plates 22 are suspended in series by ropes in the culture pond, and the bottom breathable load plate 22 is fixed to the bottom of the pond by a rope net or fixed by a heavy object to resist the vibration of water waves in the culture pond, and the pipes are arranged under the bottom breathable load plate. All of the above methods can form a multi-level plane structure.

[0026] See also Figure 3 The assembly plate 23 is arranged at the bottom of the breeding pond. An air pump 24 is mounted on the assembly plate 23 to connect the pipe 25. The air pump 24 and the pipe 25 provide oxygen through the bottom of the pool through the air permeable load plate 22. The upward buoyancy of the gas in the water can be used to supply oxygen to the planes of the air permeable load plates 22 arranged vertically and without limit on the number of layers. When the air floats up and contacts the air permeable load plates 22, a layer of air temporary retention thin plane will be formed under the air permeable load plates, increasing the contact area and time between the air and the water. Because there is one more layer of air permeable load plates 22, one more layer of air temporary retention thin plane will be generated, so that the contact area and time between the air and the water will grow exponentially with the number of layers of the air permeable load plates 22, which can increase the dissolved oxygen content in the water and reduce the volatilization utilization rate of oxygen in the traditional single plane structure.

[0027] At the same time, the submerged motor creates a horizontal water flow, and the air pump creates a vertical water flow, which is combined into a water flow without dead ends, so that feed, semi-submerged feed, algae bait, and organic debris can be spread and cultivated with the water flow; and the excrement is pumped out by the submerged motor and treated by external water purification facilities to remove ammonia nitrogen, and then returned to the breeding pond for circulating water breeding. The submerged motor is placed in the breeding pond and is mainly used to absorb the water in the breeding pond for filtration.

[0028] The assembly plate 23 is mainly used to accommodate the air pump 24 and the pipes 25 . The assembly plate 23 may be in different shapes in different embodiments.

[0029] In one embodiment, the ventilation holes of the ventilation loading plate 22 are polygonal holes.

[0030] In one embodiment, the pipe 25 includes a round tube or a long rod with a polygonal cross section and has a vent hole.

[0031] In one embodiment, the air pump 24 is disposed on the shore away from the water surface according to the water level of the breeding pond.

[0032] In one embodiment, the pipes 25 are also disposed on the sides or below the culture pond.

[0033] The utility model can form the diffusion effect of water convection and oxygen exchange to achieve a stable dissolved oxygen content. In this way, it can increase the breeding space and ensure the concentration of dissolved oxygen in the water. Through this breeding method, the yield of benthic aquatic animals can be increased and the recycling of water-saving breeding can be achieved at the same time.

[0034] Traditional aquaculture for aquatic animals living in the bottom and in the sand is based on a single plane structure, which limits the yield. The advantage of the multi-level plane structure is that it can create multiple planes for aquaculture, that is, it can harvest multiple yields.

[0035] When the first embodiment of the utility model is actually implemented:

The assembly plate 23 is equipped with an air pump 24 connected to the pipe 25, and oxygen is provided through the bottom of the breathable load plate 22 at the bottom of the pond. By using the upward buoyancy of the gas in the water, oxygen can be provided to the collective vertically arranged and unlimited number of breathable load plates 22 at the same time, and the upward buoyancy of the gas in the water can be used to achieve water convection and oxygen exchange (please refer to Figure 2 , Figure 3 shown).

[0038] 3. Water flow control: Use submerged motor and air pump 24 to create lateral and vertical water flow, achieve water flow without dead ends, and promote feed diffusion and excrement treatment.
