Description

Technical Field

[0001] This utility model relates to the field of aquaculture, and in particular to a water circulation system for the industrialized three-dimensional aquaculture of giant freshwater prawns. Background Technology

[0002] Animal husbandry refers to the production activities of artificially raising and cultivating animals or growing plants to obtain food, economic value or other uses. It is an important agricultural production method and is widely used in agriculture, fishery, animal husbandry and forestry.

[0003] The industrialized three-dimensional aquaculture system for giant freshwater prawns is an intensive, intelligent, and sustainable aquaculture system specifically designed for the efficient and stable cultivation of giant freshwater prawns.

[0004] The existing three-dimensional water circulation system for industrialized aquaculture of giant freshwater prawns has the following shortcomings: In the current practical application of giant freshwater prawn (Macrobrachium rosenbergii) box culture technology, the common approach is to use box culture and filtration components. This involves placing the prawns in a culture box and relying on the accompanying filtration components to purify the water and maintain the necessary water quality conditions for culture. However, this approach has significant technical shortcomings. The internal filtration structure of most filtration components is designed to be fixed and cannot be disassembled or separated. As the culture time increases, the filtration structure gradually accumulates impurities such as prawn feces and uneaten feed. Because it cannot be disassembled, it is difficult to thoroughly clean the deep impurities inside. Over time, the pores of the filtration structure become clogged, reducing water flow efficiency and significantly decreasing the ability to intercept and decompose pollutants. Ultimately, this leads to a continuous decline in the overall filtration effect, which not only affects the survival environment of the giant freshwater prawn but may also increase the risks of culture. Utility Model Content

[0005] This invention facilitates deep cleaning or replacement, effectively avoiding the decrease in filtration efficiency caused by the accumulation of impurities in traditional fixed structures, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a three-dimensional water circulation system for industrialized aquaculture of giant freshwater prawns, including a filtration mechanism, the inner wall of which is fixedly connected to a drainage mechanism; the filtration mechanism includes a housing, a filter box fixedly connected to the front of the housing, positioning blocks slidably connected to the inner walls of the filter box, sealing gaskets fixedly connected to the tops of the positioning blocks, nylon filter screens, biochemical cotton, and filter cotton fixedly connected to the inner walls of the sealing gaskets respectively, compression springs fixedly connected to the bottom of the inner walls of the filter box, a hinged flip cover connected to the top of the filter box, a connecting block fixedly connected to the front of the filter box, and a rotating shaft movably inserted into the top of the connecting block. These components facilitate cleaning or replacement of the filtration structure, preventing clogging of the filter pores after long-term use.

[0007] Preferably, the top hinge of the box is connected to an escape-proof fence, which can directly prevent shrimp from escaping from the top of the box, thus avoiding seedling loss during the breeding process.

[0008] Preferably, a set of air stones is fixedly installed on the bottom of the inner wall of the box, and an air pump is fixedly installed on the back of the box. The output end of the air pump is fixedly connected to a connecting pipe, which is connected to the inside of the air stones. The air pump delivers air to the air stones through the connecting pipe. The tiny bubbles released by the air stones can significantly increase the dissolved oxygen in the water, preventing the shrimp from losing vitality or dying due to insufficient dissolved oxygen.

[0009] Preferably, a PLC controller is fixedly installed on one side of the front of the box, and the PLC controller enables intelligent control of the breeding process.

[0010] Preferably, one end of the compression spring is fixedly connected to the bottom of the inner wall of the filter box. This fixed connection method improves the durability of the structure and prevents the compression spring from falling off or becoming misaligned after long-term use.

[0011] Preferably, a rotating plate is fixedly connected to the top end face of the rotating shaft, and an anti-slip pad is fixedly connected to the bottom of the rotating plate. The rotating plate can rotate around the rotating shaft. After the flip cover is closed, rotating the rotating plate can quickly fix the flip cover and prevent the flip cover from opening accidentally during the breeding process. It also indirectly restricts the multiple compression springs.

[0012] Preferably, a water inlet pipe is fixedly connected to one side of the outer wall of the filter box, a water pump is fixedly connected to the outer wall of the filter box, and a return pipe is fixedly connected to the output end of the water pump. The water inlet pipe and the return pipe are connected to the interior of the box. The water pump provides power for water circulation, and the water circulation efficiency can be controlled to ensure that the filtered clean water is quickly returned.

[0013] Preferably, a set of first stainless steel filter screens is fixedly connected to the inner wall of the box at the position of the return pipe and the inlet pipe. The setting of the first stainless steel filter screen can prevent shrimp from entering the return pipe and the inlet pipe.

[0014] Preferably, the drainage mechanism includes a water outlet pipe, and a set of second stainless steel filter screens are fixedly connected to the inner wall of the water outlet pipe. The second stainless steel filter screens can intercept shrimp larvae or small shrimp bodies in the water when draining, so as to prevent the shrimp bodies from being lost with the water during the drainage process and reduce aquaculture losses.

[0015] Preferably, a set of drain valves is fixedly connected to the outer wall of the water outlet pipe, and the drain valves can be set to flexibly control the drainage volume and drainage speed.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the filter box is equipped with a positioning block that slides with the box body. Utilizing the elastic force of the compression spring, the nylon filter screen, biochemical cotton, and filter cotton can be easily removed as a whole, facilitating deep cleaning or replacement. This effectively avoids the problem of decreased filtration efficiency caused by the accumulation of impurities in traditional fixed structures. The sealing gasket design prevents leakage of unfiltered water, ensuring the complete operation of the coarse filtration, fine filtration, and biological purification processes, and continuously maintaining clean and stable water quality. In addition, the top of the box is equipped with an escape-proof fence, effectively preventing giant freshwater prawns from climbing and escaping, significantly reducing seedling losses. The bottom is equipped with air stones connected to an air pump to release microbubbles, greatly increasing the dissolved oxygen content of the water and preventing the prawn population from declining in vitality due to lack of oxygen, creating a healthy and stable growth environment for the giant freshwater prawns.

[0017] 2. In this utility model, the PLC controller can realize intelligent control of equipment such as water pumps and air pumps, eliminating the need for real-time manual monitoring and effectively reducing labor costs. The inlet pipe, water pump, and return pipe form a closed-loop circulation system, efficiently completing water purification and recycling, significantly reducing water waste. At the same time, the system is equipped with double stainless steel filter screen protection. The first layer of filter screen prevents adult shrimp or shrimp bodies from accidentally entering the pipe and causing blockage. The second layer of filter screen intercepts shrimp larvae during drainage, preventing them from being lost with the water flow. The drainage valve is flexibly designed, allowing for precise control of the drainage volume. It is easy to operate and ensures the safety and controllability of the aquaculture process.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Please see Figures 1-6 This utility model provides a technical solution: a water circulation system for industrialized three-dimensional aquaculture of giant freshwater prawns, including a filtration mechanism 1, with a drainage mechanism 2 fixedly connected to the inner wall of the filtration mechanism 1; the filtration mechanism 1 includes a box 101, with a filter box 111 fixedly connected to the front of the box 101, positioning blocks 112 slidably connected to the inner wall of the filter box 111, sealing gaskets 114 fixedly connected to the top of the positioning blocks 112, nylon filter screens 115, biochemical cotton 116, and filter cotton 117 fixedly connected to the inner wall of the sealing gaskets 114 respectively, compression springs 113 fixedly connected to the bottom of the inner wall of the filter box 111, a hinged cover 118 connected to the top of the filter box 111, and a connecting block 122 fixedly connected to the front of the filter box 111, with a rotating shaft 121 movably inserted into the top of the connecting block 122. Through the above components, it is convenient to clean or replace the filter structure, avoiding clogging of the filter pores after long-term use.

[0023] like Figure 2 As shown, the top hinge of the box 101 is connected to an escape-proof fence 104, which can directly prevent shrimp from escaping from the top of the box 101, thus avoiding seedling loss during the breeding process.

[0024] like Figure 3As shown, a set of air stones 106 are fixedly installed on the bottom of the inner wall of the box 101, and an air pump 108 is fixedly installed on the back of the box 101. The output end of the air pump 108 is fixedly connected to a connecting pipe 107, which is connected to the inside of the air stones 106. The air pump 108 delivers air to the air stones 106 through the connecting pipe 107. The tiny bubbles released by the air stones 106 can greatly increase the dissolved oxygen in the water, thus preventing the shrimp from losing vitality or dying due to insufficient dissolved oxygen.

[0025] like Figure 2 As shown, a PLC controller 103 is fixedly installed on one side of the front of the housing 101. The PLC controller 103 enables intelligent control of the breeding process.

[0026] like Figure 4 As shown, one end of the compression spring 113 is fixedly connected to the bottom of the inner wall of the filter box 111. The fixed connection method improves the durability of the structure and prevents the compression spring 113 from falling off or becoming misaligned after long-term use.

[0027] like Figure 5 As shown, a rotating plate 119 is fixedly connected to the top end face of the rotating shaft 121, and an anti-slip pad 120 is fixedly connected to the bottom of the rotating plate 119. The rotating plate 119 can rotate around the rotating shaft 121. After the flip cover 118 is closed, rotating the rotating plate 119 can quickly fix the flip cover 118, preventing the flip cover 118 from opening accidentally during the breeding process. It also indirectly restricts the multiple compression springs 113.

[0028] like Figure 2 and Figure 4 As shown, an inlet pipe 102 is fixedly connected to one side of the outer wall of the filter box 111, and a water pump 110 is fixedly connected to the outer wall of the filter box 111. A return pipe 109 is fixedly connected to the output end of the water pump 110. The inlet pipe 102 and the return pipe 109 are connected to the interior of the housing 101.

[0029] like Figure 3 As shown, a set of first stainless steel filter screens 105 are fixedly connected to the inner wall of the box 101 at the position of the return pipe 109 and the inlet pipe 102. The first stainless steel filter screens 105 are set to prevent shrimp from entering the return pipe 109 and the inlet pipe 102.

The second stainless steel filter screens 202 can intercept shrimp larvae or small shrimp bodies in the water when draining, so as to prevent the shrimp bodies from being lost with the water during the drainage process and reduce the loss of aquaculture.

[0031] like Figure 6As shown, a set of drain valves 203 are fixedly connected to the outer wall of the water outlet pipe 201. The drain valves 203 can flexibly control the drainage volume and drainage speed.

[0032] The device's operation and working principle are as follows: Aquaculture water enters the filter box 111 through the inlet pipe 102. The first stainless steel filter screen 105 effectively intercepts shrimp, preventing them from entering the pipe and causing blockage. The water entering the filter box 111 then passes through the nylon filter screen 115 for coarse filtration, the biochemical cotton 116 for fine filtration and preliminary biochemical purification, and the filter cotton 117 for final filtration. The clean water, after multi-stage filtration, is then pumped back to the tank 101 via the return pipe 109 under the power of the water pump 110, creating a closed-loop circulation system with the tank 101 as the starting and ending point. The water purification and return are completed via the inlet pipe 102, filter box 111, water pump 110, and return pipe 109, achieving... The system features efficient recycling, reducing water waste. Furthermore, the positioning block 112 and filter box 111 adopt a sliding connection structure, and with the elastic pressure of the bottom spring 113, all filter media can be easily removed for cleaning or replacement after opening the flip cover 118. The flip cover 118 is fixed above the filter box 111 by the rotating shaft 121, rotating plate 119 and anti-slip pad 120, ensuring safe and stable operation and effectively avoiding the decrease in filtration efficiency due to the accumulation of impurities. The entire system can be operated by intelligently controlling the operating parameters of key equipment such as water pump 110 and air pump 108 through the PLC controller 103, realizing automated management without the need for real-time manual supervision, and significantly improving the stability, safety and operating efficiency of the aquaculture system.
