Description

Technical Field

[0002] With the improvement of aquaculture technology and the expansion of market demand for high-quality and diverse aquatic products, my country's aquaculture industry has developed rapidly in recent years. Traditional outdoor pond farming and river cage farming, which used to rely on the weather, are being replaced on a large scale by environmentally controllable factory farming.

[0003] In actual factory farming, to balance system costs and pursue high yields, high-density farming and overfeeding are often employed. Uneaten feed and excrement from the farmed organisms accumulate at the bottom of the ponds. As the fish swim, these residues quickly dissolve and separate into suspended particulate pollutants, causing water pollution and hindering the healthy growth of the farmed organisms. Currently, the most common method for timely removal of sediment and suspended pollutants is to drain the pond and remove the fish after harvesting, followed by manual cleaning. This manual cleaning method is not only time-consuming and labor-intensive but also negatively impacts the growth of the farmed organisms, reducing yields. Utility Model Content

[0016] The present invention achieves the following technical advantages over the prior art:

[0017] The aquaculture pond provided by this utility model features an inclined bottom, with the first end higher than the second end. This allows waste generated during the aquaculture process to naturally move towards the lower second end under gravity. Simultaneously, an inclined plate at the right-angle connection between the pond bottom and the corresponding side wall of the aquaculture chamber forms a water inlet channel. During water intake, water flows along this channel and exits through various outlets at the connection point with the pond bottom, flushing away waste and facilitating its movement towards the discharge area. All water inlet channels are interconnected and have multiple outlets located at the connection point between the inclined plate and the pond bottom. Water flows evenly from the outlet holes, thoroughly and uniformly flushing the bottom of the aquaculture area. This washes up dirt from every corner and moves it towards the drainage area, preventing dirt from accumulating in dead corners. A partition divides the aquaculture chamber into an aquaculture zone and a drainage zone. The bottom drainage holes at the lower end of the partition allow heavier dirt, such as uneaten feed and feces, to enter the drainage zone from the bottom of the aquaculture zone. The top surface drainage holes remove floating debris such as oil film and foam from the surface of the aquaculture zone, achieving stratified drainage and improving efficiency. Stratified drainage allows for targeted cleaning of different types of waste without affecting the normal activities of the aquaculture organisms. The system is designed to prevent contamination from various locations, such as the bottom drain assembly, which, when draining bottom contaminants, will not cause significant disturbance to the aquaculture organisms in the upper layers of the aquaculture area due to excessive water flow; the surface drain assembly, when cleaning surface floating matter, will not stir up the bottom water and affect the aquaculture organisms at the bottom; the bottom drain pipes installed at the bottom of the drain area can promptly discharge large amounts of contaminants flowing from the aquaculture area to the bottom of the drain area; the surface drain pipes installed on the side walls can discharge some liquid and lighter floating matter from the surface of the drain area. Together, these measures ensure rapid and thorough removal of contaminants from the drain area, preventing contaminants from accumulating in the drain area and flowing back into the aquaculture area; and the system also ensures that adjacent aquaculture areas within the same area can effectively drain contaminants. The inclined sealing blocks installed at the right-angle connections of the side walls of the breeding chamber, with obtuse angles between their connecting inclined surfaces and the side walls of the breeding chamber, along with the inclined plates and partitions, ensure that there are no dead corners in any part of the breeding area. This reduces the accumulation of waste in these areas and effectively minimizes the buildup of waste within the breeding zone. By utilizing the distribution and flow of the incoming water, the inclined surface of the pool bottom, and the reduction of dead corners, waste can be cleaned without removing the farmed organisms from the breeding area. Waste can be cleaned promptly during the water inflow and outflow process, saving time and effort and ensuring the cleanliness of the breeding water as well as the growth and yield of the farmed organisms.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The purpose of this utility model is to provide a breeding pond to solve the problems existing in the prior art, facilitate the timely cleaning of waste, save time and effort, and ensure the growth and yield of the cultured organisms.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1

[0034] This embodiment provides a culture pond, mainly used for aquaculture, such as... Figures 1-6 As shown, the device includes a pool body 10, which has at least one aquaculture chamber 11. The bottom of the aquaculture chamber 11 is an inclined surface. The inclined surface has a first end 12 and a second end 13 opposite to the first end 12. In the vertical direction, the first end 12 is higher than the second end 13. A partition plate 40 is provided inside the aquaculture chamber 11, which divides the aquaculture chamber 11 into an aquaculture area 20 and a sewage discharge area 30. The first end 12 is located in the aquaculture area 20 opposite to the partition plate 40. Inclined plates 21 are provided at the right-angle connections between the bottom of the pool and the corresponding sidewall of the aquaculture chamber 11 in the aquaculture area 20. The inclined plates 21 and each right-angle connection form corresponding water inlet channels. The channels are interconnected; and at the right-angle connection of the side walls of two adjacent breeding chambers 11 in the breeding area 20, there are inclined blocking blocks 26. The inclined blocking blocks 26 have connecting inclined surfaces 261, and the angle between the connecting inclined surfaces 261 and each side wall of the breeding chamber 11 is an obtuse angle. Each water inlet channel is used for water inlet, and each water inlet channel has multiple water outlet holes 22. Each water outlet hole 22 is located at the connection between the inclined plate 21 and the bottom of the breeding area 20. The lower end of the partition plate 40 has a bottom sewage discharge hole group, and the upper end of the partition plate 40 has a surface sewage discharge hole group 46. The bottom of the sewage discharge area 30 is provided with a bottom drain pipe 31, and the side wall of the sewage discharge area 30 is provided with a surface drain pipe 32.

[0035] By setting the bottom of the breeding chamber 11 as an inclined surface, with the first end 12 higher than the second end 13, the waste generated during the breeding process can naturally move towards the lower second end 13 under the action of gravity. At the same time, the inclined plate 21 set at the right angle connection between the bottom of the breeding area 20 and the corresponding side wall of the breeding chamber 11 forms a water inlet channel. When water is introduced, the water flow can flow along the water inlet channel and be discharged from each water outlet 22 at the connection with the bottom of the pool, which plays a role in flushing the waste at the bottom of the pool and making it easier for the waste to move towards the sewage discharge area 30. Each water inlet channel is interconnected and has multiple water outlets 22. The water outlets 22 are located at the connection between the inclined plate 21 and the bottom of the breeding area 20. When water is introduced, the water flows from the water outlets. The water flows out evenly from the 22nd section, thoroughly and uniformly flushing the bottom of the aquaculture area 20. This washes up dirt from every corner and moves it towards the sewage discharge area 30, preventing dirt from accumulating in dead corners. The partition plate 40 divides the aquaculture chamber 11 into the aquaculture area 20 and the sewage discharge area 30. The bottom sewage discharge holes at the lower end of the partition plate 40 allow heavier dirt, such as uneaten feed and feces, to enter the sewage discharge area 30 from the bottom of the aquaculture area 20. The top surface sewage discharge holes 46 can discharge some floating debris, such as oil film and foam, from the surface of the aquaculture area 20, achieving stratified sewage discharge and improving sewage discharge efficiency. Stratified sewage discharge allows for targeted cleaning of different types and locations without affecting the normal activities of the aquaculture organisms. The bottom drainage holes, when discharging bottom waste, will not cause significant disturbance to the aquaculture organisms in the upper layers of the aquaculture area 20 due to excessive water flow; the surface drainage holes 46, when cleaning surface floating matter, will not stir up the bottom water and affect the aquaculture organisms at the bottom; the bottom drain pipe 31 installed at the bottom of the drainage area 30 can promptly discharge a large amount of waste flowing from the aquaculture area 20 to the bottom of the drainage area 30; the surface drain pipe 32 installed on the side wall can discharge some liquid and lighter floating matter from the surface of the drainage area 30. Together, these two systems can quickly and thoroughly discharge waste from the drainage area 30, preventing waste from accumulating in the drainage area 30 and flowing back into the aquaculture area 20; adjacent drainage holes within the aquaculture area 20... The inclined sealing block 26 installed at the right-angle connection of the side wall of each aquaculture chamber 11 has an obtuse angle between its connecting inclined surface 261 and each side wall of the aquaculture chamber 11. The inclined plates 21 and the inclined partition plates 40 are all designed to ensure that there are no dead corners in any part of the aquaculture area 20, reducing the accumulation of dirt in dead corners and effectively reducing the accumulation of dirt in the aquaculture area 20. By utilizing the distribution and flow of the incoming water, the inclined surface of the pool bottom, and the reduction of dead corner areas, dirt can be cleaned without removing the aquaculture animals from the aquaculture area 20. Dirt can be cleaned in a timely manner during the water inflow and outflow process, saving time and effort, and ensuring the cleanliness of the aquaculture water and the growth and yield of the aquaculture animals.

[0036] Specifically, a temporary baffle can be set on the side of the partition plate 40 near the breeding area 20, so that after the water in the sewage area 30 flows away, the water in the breeding area 20 still exists, while the sewage area 30 has no water, and the sewage area 30 can be rinsed and cleaned separately.

[0037] The following are the relevant settings instructions for pool 10:

[0038] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 2 As shown, the pond 10 includes multiple culture chambers 11, which are arranged in parallel and isolated from each other. These multiple culture chambers 11 can be used to culture the same species or different species. They can be classified according to the species, size, growth stage, and growth habits of the cultured organisms. For example, in aquaculture, different species of fish, shrimp, and crabs can be placed in different culture chambers 11 to avoid competition for food and space, or to prevent larger fish from eating smaller fish or the strong from bullying the weak, thus improving the survival rate and growth quality of the cultured organisms. Each culture chamber 11 can be independently managed for feeding, water quality monitoring, and disease prevention. Aquaculture personnel can precisely control the amount of feed and medication used according to the specific needs of the cultured organisms in each chamber 11, improving feed utilization and reducing waste. They can also better observe and understand the growth status of the cultured organisms in each chamber 11, promptly identify problems, and take appropriate measures.

[0039] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 2 As shown, each aquaculture chamber 11 is connected to a main inlet pipe 14 via an inlet water pipe, which is connected to the water inlet channel of the aquaculture chamber 11. Furthermore, the bottom drain pipe 31 and surface drain pipe 32 of each aquaculture chamber 11 are connected to a main drainage pipe 15. The main inlet pipe 14 provides a unified water source for all aquaculture chambers 11, ensuring a stable water supply for each chamber. This reduces the cost and complexity of setting up separate inlet facilities for each chamber, improving water supply efficiency. The connection between the bottom drain pipe 31 and surface drain pipe 32 of each aquaculture chamber 11 and the main drainage pipe 15 enables centralized discharge of wastewater from each chamber. This avoids environmental pollution and management inconvenience caused by scattered wastewater discharge around the aquaculture pond, improving drainage efficiency and ensuring timely discharge of wastewater from the aquaculture pond. By concentrating the wastewater from each aquaculture chamber 11 into the main drainage pipe 15, wastewater can be collected and treated uniformly, facilitating the use of centralized wastewater treatment equipment and processes, such as biological treatment and physicochemical treatment. This reduces wastewater treatment costs, improves treatment efficiency, and reduces environmental pollution.

[0040] The following are the settings instructions for the partition plate 40:

[0041] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 2 and Figure 5 As shown, the partition plate 40 includes a first side plate 41, a second side plate 43, and a middle plate 42; the first side plate 41 and the second side plate 43 are located on both sides of the middle plate 42; the end of the first side plate 41 and the second side plate 43 closer to the middle plate 42 is closer to the sewage discharge area 30 than the end farther from the middle plate 42; the lower ends of the first side plate 41 and the second side plate 43 are each provided with a first bottom drainage hole group 44, and the lower end of the middle plate 42 is provided with a second bottom drainage hole group 45, the height of the second bottom drainage hole group 45 being higher than the height of the first bottom drainage hole group 44. The size of each row of holes in the first bottom row hole group 44 and the second bottom row hole group 45 is the same, but the number of rows in the height direction of the first bottom row hole group 44 is less than that of the second bottom row hole group 45. For example, the first bottom row hole group 44 has two rows in the vertical direction, and the second bottom row hole group 45 has at least three rows in the vertical direction, so that the height of the second bottom row hole group 45 is higher than that of the first bottom row hole group 44; the first bottom row hole group 44 and the second bottom row hole group 45 together form the bottom drain hole group; and the upper end of the middle plate 42 is provided with a surface drain hole group 46. The first bottom drainage hole group 44 is located at the lower end of the first side plate 41 and the second side plate 43, and the second bottom drainage hole group 45 is located at the lower end of the middle plate 42 and is higher than the first bottom drainage hole group 44. This design enables layered drainage. The sewage at the bottom of the breeding chamber 11 often contains more solid waste and denser pollutants, which can be preferentially discharged through the first bottom drainage hole group 44; while the sewage with relatively fewer impurities and located at a slightly higher position can be discharged through the second bottom drainage hole group 45, improving the efficiency and thoroughness of sewage discharge and more effectively maintaining the breeding area. The water in the 20th pond is kept clear; and when there is too much sediment at the bottom of the pond, the sediment can flow along the inclined first side plate 41 and second side plate 43 to the lower end of the middle plate 42 and be discharged through the second bottom drain hole group 45, which is suitable for the smooth discharge of more sediment; the surface drain hole group 46 is set at the upper end of the middle plate 42 and can be used to discharge sewage or foam from the surface of the aquaculture area 20. When oil, foam or floating objects caused by feeding appear on the surface of the aquaculture water, they can be discharged in time through the surface drain hole group 46 to keep the surface of the water clear.

[0042] Specifically, the surface drain hole group 46 and the second bottom drain hole group 45 can have the same hole diameter and hole arrangement.

[0043] The following are the relevant instructions regarding the setup of breeding area 20:

[0044] Specifically, regarding the relevant measures to reduce waste accumulation within the breeding area (within 20 square meters):

[0045] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 3 and Figure 4As shown, the inclined plate 21 located at the first end 12 is connected to the adjacent inclined plates 21 on both sides via a connecting transition inclined plate 25, and the inclined surface of the connecting transition inclined plate 25 near the aquaculture area 20 has an obtuse angle with each adjacent surface. The connection between the inclined plate 21 at the first end 12 and the adjacent inclined plates 21 on both sides via the connecting transition inclined plate 25 guides the water flow in the inlet channel to flow more smoothly. Since the inclined surface of the connecting transition inclined plate 25 near the aquaculture area 20 has an obtuse angle with each adjacent surface, this design reduces resistance when the water flow turns or converges, preventing the formation of dead zones or vortices, and allowing the water flow to be evenly distributed within the aquaculture area 20 according to the designed path, thereby better realizing water circulation and renewal. The setting of the inclined plate 21 and the connecting transition inclined plate 25 creates a specific inclined structure at the bottom of the aquaculture pond. During the breeding process, waste such as feces and uneaten feed are more easily collected along the inclined plate 21 and the connecting transition inclined plate 25 towards the lower-lying second end 13 or the sewage discharge area 30 under the action of water flow. This facilitates centralized cleaning, reduces the residue of waste in the breeding area 20, reduces the difficulty of cleaning, and saves cleaning time and labor costs. The obtuse angle design makes the included angle between adjacent inclined surfaces larger, reducing the possibility of waste accumulating in corners or gaps. This avoids water quality deterioration and bacterial growth caused by waste residue, which helps to keep the breeding pond clean and hygienic and provides a good growth environment for the aquaculture organisms.

[0046] Specifically, regarding the oxygen supply settings within the breeding area 20:

[0047] Among the optional solutions in this embodiment, the more preferred one is as follows: Figures 1-4 As shown, a micro-nano aeration tube 23 for supplementing oxygen is fixedly installed above the water inlet channel at the first end 12. The micro-nano aeration tube 23 has multiple aeration holes. The micro-nano aeration tube 23 can release air into the water in the form of micro-nano bubbles through the aeration holes. These tiny bubbles have a large specific surface area, allowing for full contact with water, greatly improving the oxygen dissolution efficiency in the water, providing more dissolved oxygen for the aquatic organisms, meeting their respiratory needs, and promoting their growth and development.

[0048] In the optional embodiments of this example, a preferred embodiment is that the air inlet of the micro-nano aeration tube 23 is connected to an air supply pipe, and a flexible ventilation tube is connected to the air supply pipe, with a micro-nano ceramic aeration disc connected to the end of the flexible ventilation tube. When needed, the micro-nano ceramic aeration disc can be placed in the aquaculture area 20; when not needed, the micro-nano ceramic aeration disc can be removed from the aquaculture area 20. The aeration intensity and position can be flexibly adjusted according to the needs of different locations in the aquaculture area 20.

[0049] Specifically, regarding the feeding arrangements within the breeding area 20:

[0050] Among the optional solutions in this embodiment, the more preferred one is as follows: Figures 1-6 As shown, a spray pipe 24 is fixedly installed above the first end 12, and the height of the spray pipe 24 is higher than the water level in the aquaculture area 20; multiple spray holes are opened on the spray pipe 24. The jet of water sprayed from the spray holes is used to attract carnivorous fish such as mandarin fish to eat. It is turned on when feeding to attract the farmed fish to eat; the water flow and splash formed by the spray can destroy the microbial film on the water surface, inhibit the growth and reproduction of some harmful algae and microorganisms, reduce the possibility of them forming foam or harmful bacteria on the water surface, and reduce the risk of disease infection in farmed organisms; it can also simulate the state of natural rainfall or water flow, providing farmed organisms with a living environment closer to nature, which helps to reduce the stress response of farmed organisms, enabling them to better adapt to the aquaculture environment and improve their growth performance and immunity.

[0051] The following are the relevant design specifications for sewage discharge zone 30:

[0052] In the optional schemes of this embodiment, it is more preferred that the inlet of the bottom drain pipe 31 is located at the lowest point of the bottom of the sewage discharge area 30.

[0053] Specifically, the bottom of the sewage discharge area 30 can be an arc-shaped surface, and the inlet of the bottom drain pipe 31 is located at the lowest point of the bottom of the sewage discharge area 30 to facilitate the smooth discharge of dirt and improve the sewage discharge efficiency. It can promptly discharge the waste generated during the breeding process out of the pond and keep the breeding water clean. The bottom drain pipe 31 can automatically discharge most of the sewage and impurities, greatly reducing the workload and frequency of manual cleaning of the pond bottom, and reducing the labor intensity and labor costs in the breeding process.

[0054] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 2 and Figure 3 As shown, valves are installed on both the bottom drain pipe 31 and the surface drain pipe 32. By controlling the valves, the discharge volume of bottom sewage can be precisely controlled as needed. When a complete water change or cleaning of bottom impurities is required, the valve can be opened wide for rapid discharge; when only minor adjustments to the water quality are needed, the valve can be opened slightly to slowly discharge the sewage. The valve on the surface drain pipe 32 can control the discharge of surface water. For example, when there are impurities such as foam or oil on the water surface, opening the valve on the surface drain pipe 32 can specifically discharge the dirty surface water.

[0055] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
