Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a multi-species aquaculture pond. Background Technology

[0002] Multi-species aquaculture ponds simultaneously raise multiple aquatic organisms in the same water body to improve resource utilization and environmental sustainability. Taking bullfrogs, fish, and shrimp as an example, this model utilizes the different positions and ecological habits of different species in the food chain to achieve mutual benefit and symbiosis. Fish (such as herbivorous or filter-feeding fish) can consume plankton and plants in the water to control water quality, while shrimp mainly move on the bottom of the pond, foraging for uneaten food and organic debris to help clean the bottom. Bullfrogs can not only prey on small organisms such as insects, but also provide nutrients to the water through their excrement, promoting the cycle of the entire ecosystem.

[0003] Chinese Patent Publication No. CN222396686U discloses a multi-species aquaculture pond. This patent includes a pond body, a feeding mechanism, and an interception mechanism. Multiple interception mechanisms are located on the inner side of the pond body, and the feeding mechanism is slidably positioned above the pond body. Multiple sets of interception mechanisms are arranged side-by-side on the inner side of the pond body. Each interception mechanism includes an interception mesh plate and a connecting rod. A slider protrudes from the outer periphery of the interception mesh plate, and a matching groove is formed on the inner wall of the pond body. This multi-species aquaculture pond divides the interior of the pond body into multiple independent spaces, allowing for the separate cultivation of different aquatic species and facilitating the harvesting and counting of aquatic products.

[0004] In existing technologies, the complete isolation of the aforementioned zoned aquaculture hinders the free exchange of water and the cycling of ecological substances, easily leading to water quality imbalance and reduced self-purification capacity in different areas, thus affecting the overall stability of the aquaculture environment. Based on this, this invention designs a multi-species polyculture pond to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a multi-species aquaculture pond.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A multi-species aquaculture pond includes a pond, an inlet pipe connected to the interior is installed on the top of the right outer wall of the pond, a drain pipe connected to the interior is installed on the bottom of the left outer wall of the pond, an ecological purification component is installed at the bottom of the interior of the pond, and a microbial slow-release component is installed inside the pond. The ecological purification component includes a biological filter layer fixedly installed on the bottom wall of the aquaculture pond, a filter adsorption layer fixedly connected to the top surface of the biological filter layer, a vegetation floating bed layer installed on the top surface of the filter adsorption layer, and multiple microporous aeration discs installed on the top surface of the vegetation floating bed layer. The microbial slow-release component includes multiple mounting slots fixedly connected to the inner wall of the aquaculture tank. A connecting block is snapped into the inside of each mounting slot, and a connecting rod is connected between two connecting blocks on the left and right sides. Multiple microbial slow-release boxes are fixedly installed on the connecting rod.

[0007] Furthermore, the interior of the microbial slow-release box is filled with compound probiotics, and the outer wall of the microbial slow-release box has multiple holes that connect to the interior.

[0008] Furthermore, the top opening of the microbial slow-release box is connected to a cover plate by a hinge, and a pull rod is installed on the outer surface of the cover plate. Threaded grooves are opened on the top side of the cover plate and the microbial slow-release box, and a fixing rod is threadedly connected between the inner and outer threads of the upper and lower threads.

[0009] Furthermore, both the mounting groove and the connecting block are provided with positioning grooves, and a screw is threaded between the interior of the two positioning grooves.

[0010] Furthermore, both the inlet and outlet pipes are fixedly connected with filter screens.

[0011] Furthermore, an oxygenator is fixedly connected to the outer right wall of the aquaculture pond, and an aeration pipe is installed on the oxygenator.

[0012] Furthermore, one end of the aeration pipe is inserted into the interior of the aquaculture pond and fixedly connected to multiple aeration branch pipes, and microporous aeration discs are fixedly connected to the aeration branch pipes.

[0013] Furthermore, the filter adsorption layer is made of quartz sand and activated carbon, and the biological filter layer is made of a mixture of volcanic rock and biospheres.

[0014] Beneficial effects This invention achieves multi-level purification of aquaculture water through the synergistic effect of a vegetation floating bed layer, a filter adsorption layer, and a biofilter layer. The vegetation floating bed layer utilizes plant roots to absorb nutrients such as nitrogen and phosphorus, effectively inhibiting excessive algae growth. The filter adsorption layer removes suspended solids, uneaten feed, and dissolved organic pollutants through physical interception and chemical adsorption. The biofilter layer degrades harmful metabolic products such as ammonia nitrogen and nitrite, significantly improving water quality stability and self-purification capacity. This avoids the phenomenon of water quality imbalance and decreased self-purification capacity caused by the isolation of aquaculture zones hindering free water exchange and ecological material cycling.

[0015] This invention achieves precise delivery and uniform release of high-concentration oxygen through the coordinated operation of an oxygen generator, aeration pipe, microporous aeration disc, and aeration branch pipe. The microporous aeration disc generates tiny bubbles at the bottom of the pond, significantly improving oxygen dissolution efficiency. Combined with the aeration branch pipe, it expands the aeration range, ensuring sufficient dissolved oxygen in the bottom water, promoting the respiratory metabolism of bullfrogs, fish, shrimp, and other species, as well as the activity of aerobic microorganisms, and preventing stress and death caused by hypoxia.

[0016] This invention achieves continuous slow release and full-area diffusion of probiotics through the even distribution of multiple microbial slow-release boxes. The compound probiotics are slowly released through the holes, effectively decomposing organic waste such as uneaten feed and feces, inhibiting the proliferation of pathogens such as Vibrio, and maintaining the micro-ecological balance of the water body. When the bacterial agent is insufficient, the microbial slow-release box can be removed from the aquaculture pond through the cooperation of the connecting block, installation, positioning groove and screw, and the cover can be opened to regularly replenish the probiotics. This achieves full-area water quality balance and continuous regulation, significantly reduces the incidence of diseases and reduces the use of drugs. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] In some embodiments, please refer to the appendix to the instruction manual. Figures 1-6 A multi-species aquaculture pond includes a pond 1. A water inlet pipe 101 is installed on the top of the right outer wall of the pond 1, which is connected to the interior. A drain pipe 102 is installed on the bottom of the left outer wall of the pond 1, which is connected to the interior. The drain pipe 102 facilitates the rapid discharge of sewage or replacement of water in the pond 1. An ecological purification component 2 is installed inside the pond 1.

[0023] In this embodiment of the utility model, the ecological purification component 2 includes a biological filter layer 203 fixedly installed on the bottom wall of the aquaculture pond 1. The biological filter layer 203 is made of a mixture of volcanic rock and biospheres. The mixture of volcanic rock and biospheres can convert toxic ammonia nitrogen in the water into nitrite, and then convert nitrite into non-toxic nitrate, thus completely eliminating the toxic effects of nitrogen pollution on the cultured organisms. A filter adsorption layer 202 is fixedly connected to the top surface of the biological filter layer 203. The filter adsorption layer 202 is made of quartz sand and activated carbon, thereby further improving the water cleanliness and creating a low-pollution environment for subsequent biological purification. A vegetation floating bed layer 201 is installed on the top surface of the filter adsorption layer 202. Aquatic plants can be planted on the vegetation floating bed layer 201. The roots of the aquatic plants absorb nutrients such as nitrate and phosphate in the water, reducing the risk of eutrophication. At the same time, the plant leaves can block some sunlight, inhibit the excessive reproduction of algae, and improve the transparency of the water.

[0024] Multiple microporous aeration discs 204 are installed on the top surface of the floating vegetation bed layer 201. An oxygenator 206 is fixedly connected to the outer right wall of the aquaculture pond 1. An aeration pipe 205 is installed on the oxygenator 206. One end of the aeration pipe 205 is inserted into the interior of the aquaculture pond 1 and fixedly connected to multiple aeration branch pipes 207. Microporous aeration discs 204 are fixedly connected to the aeration branch pipes 207, thereby transporting the oxygen generated by the oxygenator 206 to the microporous aeration discs 204 through the aeration pipes 205 and aeration branch pipes 207, supplementing the dissolved oxygen in the water inside the aquaculture pond 1. Filter screens 103 are fixedly connected inside both the inlet pipe 101 and the outlet pipe 102. The filter screens 103 can filter impurities, wild fish eggs, etc., from the water source, preventing them from entering the aquaculture pond 1 and disrupting the polyculture environment. They can also prevent farmed organisms such as juvenile shrimp and fish fry from escaping with the drainage, ensuring the stability of the farmed population.

[0025] In one embodiment of this utility model, during use, water flows slowly into the aquaculture pond 1 through the inlet pipe 101. The water first comes into contact with the aquatic plants in the floating vegetation layer 201. The roots of the aquatic plants absorb nutrients in the water and inhibit algae growth. Subsequently, the water flows into the filter adsorption layer 202, which traps suspended particles and adsorbs odors and heavy metals. The purified water continues to flow into the biological filter layer 203, where attached microorganisms decompose harmful substances such as ammonia nitrogen and nitrite. At the same time, the high-concentration oxygen generated by the oxygen generator 206 is transported to the microporous aeration disc 204 through the aeration pipe 205 and aeration branch pipe 207. Fine bubbles are generated through the micropores and evenly integrated into the water, increasing the dissolved oxygen concentration in the water.

[0026] In some embodiments, such as Figures 1-6 As shown, in a preferred embodiment of the present invention, a microbial slow-release component 3 is installed at the bottom of the aquaculture pond 1.

[0027] In this embodiment of the invention, the microbial slow-release component 3 includes multiple mounting slots 301 fixedly connected to the inner wall of the aquaculture pond 1. Connecting blocks 302 are snapped into the interior of each mounting slot 301, and connecting rods 308 connect the left and right connecting blocks 302. Multiple microbial slow-release boxes 303 are fixedly mounted on the connecting rods 308. The interior of each microbial slow-release box 303 is filled with a mixed agent of compound probiotics such as Bacillus subtilis, nitrifying bacteria, and photosynthetic bacteria. Multiple holes 305 communicating with the interior are provided on the outer wall of the microbial slow-release box 303, thereby gradually activating and releasing the probiotics into the water, continuously maintaining the number of beneficial bacteria in the water.

[0028] The top opening of the microbial slow-release box 303 is connected to a cover plate 304 by a hinge. A pull rod is installed on the outer surface of the cover plate 304. Threaded grooves are opened on the top side of the cover plate 304 and the microbial slow-release box 303. A fixing rod is threadedly connected between the upper and lower threaded grooves. Positioning grooves 306 are opened on the mounting groove 301 and the connecting block 302. A screw 307 is threadedly connected between the two positioning grooves 306.

[0029] In one embodiment of this utility model, during use, the compound probiotics filled inside the microbial slow-release box 303 are slowly released into the water of the aquaculture pond 1 through the holes 305 on the box body. After the probiotics are released, they can quickly spread to the entire water body and continuously decompose organic matter such as uneaten feed and feces in the water. When the amount of probiotics is insufficient, the screw 307 can be removed from the positioning groove 306 on the mounting groove 301 and the connecting block 302, and then the connecting block 302 can be moved upward to remove the microbial slow-release box 303 from the aquaculture pond 1. The fixing rod can be removed from the cover plate 304 and the threaded groove on the microbial slow-release box 303 with the help of a screwdriver or wrench. Then, the cover plate 304 can be opened by pulling the rod to replenish the probiotics into the microbial slow-release box 303.

[0030] The working principle of this utility model is as follows: During use, the oxygenator 206 is connected to an external power strip via a cable and socket to ensure normal power supply. Then, the water inlet pipe 101 is connected to an external clean water source. Water meeting aquaculture standards enters the aquaculture pond 1 through the water inlet pipe 101. The water flows slowly within the pond, first contacting the aquatic plants in the floating vegetation layer 201. The roots of the aquatic plants absorb nutrients from the water, inhibiting algae growth. Subsequently, the water flows into the filter adsorption layer 202, where suspended particles are trapped and odors and heavy metals are adsorbed. The purified water continues to flow into the biological filter layer 203, where attached microorganisms decompose harmful substances such as ammonia nitrogen and nitrite, completing the initial purification of the water quality. At the same time, the power supply and controller of the oxygen generator 206 are activated, so that the high concentration of oxygen generated by the oxygen generator 206 is transported to the microporous aeration disc 204 through the aeration pipe 205 and aeration branch pipe 207. The micropores generate fine bubbles, which are evenly integrated into the water body, increasing the dissolved oxygen concentration in the water body and providing oxygen support for the metabolism of farmed organisms and microorganisms, thereby meeting the growth needs of multiple species such as bullfrogs, fish, and shrimp.

[0031] Meanwhile, the compound probiotics filled inside the microbial slow-release tank 303 are gradually activated as the water slowly seeps into the tank. They are then slowly released into the aquaculture pond 1 through the holes 305 in the tank. Because multiple microbial slow-release tanks 303 are evenly distributed, the probiotics can quickly spread throughout the entire water body after release, continuously decomposing uneaten feed, feces, and other organic matter, inhibiting the reproduction of pathogens, and maintaining the balance of the aquatic flora. When the probiotic supply is insufficient, the screw 307 can be removed from the two positioning slots 306, and the installation slot 30 can be released. 1. Fix the connecting block 302 to the fixed limit, then move the connecting block 302 upward to remove the microbial slow release box 303 from the breeding pond 1. Use a screwdriver or wrench to remove the fixing rod from the threaded groove on the cover plate 304 and the microbial slow release box 303 to release the fixation on the cover plate 304 and the microbial slow release box 303. Then open the cover plate 304 with the pull rod to add probiotics to the microbial slow release box 303. The operation is convenient and ensures the continuity of the microbial regulation effect. After completion, reverse the operation to install it.

[0032] During the breeding process, if it is necessary to change the water or discharge sewage, the drain pipe 102 can be opened. The sewage will be discharged under the action of gravity or water pump. The filter screen 103 installed inside the drain pipe 102 can effectively intercept farmed organisms such as bullfrogs, fish and shrimp to prevent them from escaping. After the sewage is discharged, fresh water can be reintroduced through the inlet pipe 101 to achieve water renewal and recycling.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
