[0002] Sea shrimp, also known as red shrimp, crimson shrimp, and large green shrimp, is a general term for the meat or whole body of marine shrimp. Sea shrimp are rich in nutrients, have a delicious taste, and can be used in cooking and as a medicinal material. Sea shrimp are mainly distributed in the Yellow Sea, Bohai Sea, and sea areas north of the Yangtze River estuary, and are a specialty of China. In the dermis of aquatic crustaceans such as crabs and shrimp, there are a large amount of pigment, mostly bluish-black, which is why fresh shrimp and crabs are generally bluish-green. Astaxanthin is a terpene conjugated long-chain antioxidant with strong antioxidant function. In the early stage of seawater shrimp larvae cultivation, desalination cultivation devices are required. When using existing desalination cultivation devices, the concentration of the culture water can be diluted by adding fresh water. However, in the initial stage of adding fresh water, it is difficult to quickly and completely mix with the culture water, resulting in uneven concentration in different areas of the water and affecting the cultivation effect.

[0003] Therefore, it is necessary to provide a new shrimp larvae desalination and cultivation device to solve the above-mentioned technical problems. Utility Model Content

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

[0022] Please refer to the following: Figures 1-4 ,in, Figure 1 A top view schematic diagram of a preferred embodiment of the shrimp larvae desalination and cultivation device provided by this utility model; Figure 2 This is a top view of the desalination tank in this utility model without an isolation net installed; Figure 3 for Figure 2 An enlarged structural diagram of part A shown in the figure; Figure 4 This is a top view of the air pump box in this utility model.

[0023] The shrimp larvae desalination and rearing device includes: a base 1; a desalination tank 2 fixed on the base 1 for storing desalinated aquaculture water; a mounting plate 4 installed in the desalination tank 2 via a fixing frame 3; an exhaust pipe 5 fixed on the mounting plate 4; a regulating cylinder 8 rotatably sleeved on the exhaust pipe 5, with a stirring rod 9 fixed on the regulating cylinder 8 for stirring the desalinated aquaculture water; and an aeration structure set on the base 1 for increasing the dissolved oxygen content of the desalinated aquaculture water. By setting the regulating cylinder 8 and the stirring rod 9 fixed thereon, when adding clean water to dilute the concentration of the aquaculture water in the desalination and rearing device, the stirring rod can be used... Nine steps are taken to stir the water, ensuring that the clean water mixes quickly and completely with the aquaculture water. This effectively solves the problem of uneven concentration in different areas of the water during the initial stage of adding clean water, ensuring the balance of water concentration and thus improving the effect of shrimp larvae desalination and cultivation. It provides a more stable and suitable environment for shrimp larvae growth. By setting up an aeration structure, the dissolved oxygen content of the desalination and aquaculture water can be increased to meet the oxygen requirements of shrimp larvae during growth, ensuring normal respiration and metabolism of shrimp larvae, which is conducive to the healthy growth of shrimp larvae, improving the survival rate and quality of shrimp larvae desalination and cultivation, and enhancing the practicality and functionality of the entire shrimp larvae desalination and cultivation device.

[0024] The oxygenation structure includes an air pump box 7 fixed on the base 1. An air pump connected to the exhaust pipe 5 is installed at the exhaust end of the air pump box 7, and an air stone 6 installed in the desalination tank 2. The air stone 6 is connected to the exhaust pipe 5. By setting up the air pump box 7 and its internal air pump, and connecting the exhaust end of the air pump to the exhaust pipe 5, power can be provided for gas delivery, allowing gases such as oxygen to smoothly enter the subsequent structures. By setting up the air stone 6 and connecting it to the exhaust pipe 5, the gas delivered by the air pump reaches the air stone 6 through the exhaust pipe 5. The air stone 6 can refine the gas into tiny bubbles. These tiny bubbles diffuse evenly in the desalination tank 2, greatly increasing the contact area between the gas and the aquaculture water, thereby significantly increasing the dissolved oxygen content of the desalinated aquaculture water. This makes the oxygen supply in the shrimp larvae's growth environment more sufficient, meeting the shrimp larvae's respiratory needs, contributing to the shrimp larvae's metabolism and healthy growth, improving the success rate and quality of shrimp larvae desalination cultivation, and enhancing the cultivation efficiency of the device.

[0025] A motor box 10 is mounted on the base 1. A transmission roller 11 is rotatably mounted on one side of the air pump box 7. A servo motor with an output shaft connected to the transmission roller 11 via a coupling is provided inside the motor box 10. A rubber belt 12 for transmission is provided over the transmission roller 11 and the adjusting cylinder 8. By setting up the motor box 10 and the servo motor inside it connected to the transmission roller 11 via a coupling, a stable and controllable power source is provided for the entire transmission system, ensuring reliable power for the operation of the device. By setting up the transmission roller 11 and the rubber belt 12, the transmission roller 11 and the adjusting cylinder 8 are connected by transmission via the rubber belt 12. When the servo motor drives the transmission roller 11 to rotate, the rubber belt 12 can smoothly transmit power to the adjusting cylinder 8, thereby driving the stirring rod 9 on the adjusting cylinder 8 to rotate, thus realizing the stirring of the desalinated aquaculture water.

[0026] An isolation net 13 for preventing shrimp larvae from jumping out of the pond is fixed on the mounting plate 4. An L-shaped hanging rod for stabilizing the isolation net 13 is provided on the inner wall of the desalination pond 2. The isolation net 13 is hung on the L-shaped hanging rod. By setting up the isolation net 13, the shrimp larvae can be effectively prevented from jumping out of the pond. During the desalination and cultivation process, shrimp larvae may jump out of the pond due to external stimuli or their own activity. The isolation net 13 can confine the shrimp larvae within the desalination pond 2, preventing them from jumping out of the pond and causing losses, thus ensuring the number of shrimp larvae and the smooth progress of the cultivation work. By setting up an L-shaped hanging rod on the inner wall of the desalination pond 2 and hanging the isolation net 13 on the L-shaped hanging rod, the isolation net 13 can be stably installed in the desalination pond 2. This installation method not only facilitates the installation and disassembly of the isolation net 13 and the daily cleaning and maintenance work, but also ensures that the isolation net 13 remains stable during use and will not easily shake or fall off, further improving the practicality and reliability of the device.

[0027] The air pump box 7 has an air inlet on one side. A filter box 16, fitted over the air inlet, is detachably mounted on the air pump box 7 for filtering air. An extension plate 15, in contact with the outer wall of the filter box 16, is provided on the air pump box 7. A fixing bolt 17, threaded onto the extension plate 15 and threadedly connected to the filter box 16, is also mounted on the extension plate 15. By fitting the filter box 16 over the air inlet of the air pump box 7, it effectively filters the air. During the freshwater cultivation of shrimp larvae, dust and impurities in the air, if entering the aquaculture water, may negatively impact the growth environment of the shrimp larvae. Pollution can affect the health of shrimp larvae. Filter box 16 can effectively intercept these harmful substances, ensuring that the air entering the air pump box 7 is clean, thereby providing clean gas to the aquaculture water and helping to maintain good water quality. By setting up extension plate 15 and using fixing bolts 17 to detachably install filter box 16 on air pump box 7, the installation and removal of filter box 16 becomes convenient and quick. This facilitates regular cleaning or replacement of filter box 16, ensuring that its filtration effect is always good, guaranteeing the long-term stable operation of the device, and improving the quality and efficiency of shrimp larvae freshwater cultivation.

[0028] A cleaning rod is rotatably mounted on the stirring rod 9, contacting the inner wall of the desalination tank 2 to assist in cleaning the inner wall of the desalination tank 2. A brush pad is attached to the cleaning rod via Velcro. A drain pipe 14 is provided on one side of the desalination tank 2. By setting up a cleaning rod rotatably mounted on the stirring rod 9 and in contact with the inner wall of the desalination tank 2, the cleaning rod can move along the inner wall of the desalination tank 2 while the stirring rod 9 rotates and stirs the water, thus assisting in cleaning the inner wall of the desalination tank 2. This helps prevent impurities, algae, etc. from adhering to the inner wall of the desalination tank 2, avoiding pollution of the aquaculture water and ensuring the cleanliness of the shrimp larvae's growth environment. The brush pad is attached to the cleaning rod via Velcro, which facilitates the installation and replacement of the brush pad. When the brush pad is worn or needs cleaning, it can be easily operated. At the same time, the brush pad can more effectively remove dirt from the inner wall, improving the cleaning effect.

[0029] The motor housing 10 is equipped with a heat dissipation vent, and a dustproof mesh for isolating dust and impurities is installed inside the heat dissipation vent. A plug cap for sealing the drain pipe 14 is detachably installed on the drain pipe 14. By setting a heat dissipation vent on the motor housing 10, the servo motor inside the motor housing 10 is cooled. The servo motor generates heat during operation, and the heat dissipation vent can dissipate the heat in time, avoiding performance degradation or even damage to the motor due to overheating, ensuring the normal operation of the motor and extending its service life. The dustproof mesh installed inside the heat dissipation vent can effectively isolate dust and impurities, preventing them from entering the motor housing 10 and adhering to the motor and other components, avoiding problems such as poor heat dissipation and short circuits caused by dust accumulation, further ensuring the stable operation of the motor. The detachable plug cap on the drain pipe 14 facilitates the sealing and opening of the drain pipe 14.

[0030] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0031] The working principle of the shrimp larvae freshwater cultivation device provided by this utility model is as follows:

[0032] This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here.

[0033] In use, the desalination water for shrimp larvae rearing is injected into desalination tank 2. When it is necessary to dilute the concentration of the rearing water, clean water is added to desalination tank 2. At the same time, the servo motor in motor box 10 (taking Siemens 1FT7 servo motor as an example) is started. The servo motor drives the transmission roller 11 to rotate through the coupling. The transmission roller 11 drives the regulating cylinder 8 to rotate through the rubber belt 12. The stirring rod 9 on the regulating cylinder 8 stirs the water, so that the clean water is quickly and completely mixed with the rearing water, ensuring a balanced water concentration. The air pump in air pump box 7 is started. The air pump (taking Haili ACO series aerator as an example) draws air in through the air inlet and passes through filter box 1. After filtration, the gas is transported to the air stone 6 through the exhaust pipe 5. The air stone 6 refines the gas into tiny bubbles that diffuse evenly within the desalination tank 2, increasing the dissolved oxygen content of the desalination aquaculture water and meeting the oxygen requirements for shrimp larvae growth. During the stirring process of the stirring rod 9, the cleaning rod, which is mounted on the stirring rod 9 and in contact with the inner wall of the desalination tank 2, moves along the inner wall of the desalination tank 2. The brush pad on the cleaning rod removes dirt from the inner wall, preventing impurities, algae, etc. from adhering to the inner wall and polluting the aquaculture water. When water needs to be changed, the plug on the drain pipe 14 is removed to discharge sewage and waste into the desalination tank 2. After discharge, the drain pipe 14 is resealed with the plug.
