[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] See also Figures 1 to 4 , is a salt-alkali adaptation and acclimation device for aquatic animals as a preferred embodiment of the present invention, comprising:

[0032] The pool body 1 is provided with an evaporation suppression cover plate 11 on the top of the pool body 1, a heating device 12 is installed at the bottom of the pool body 1, and a water quality and temperature sensor 13 is installed on the inner wall of the pool body 1. The water quality and temperature sensor 13 is electrically connected to the heating device 12; wherein the evaporation suppression cover plate 11 is transparent and can reflect or absorb part of the infrared rays through selective light transmission, which can significantly reduce the evaporation loss of the water body, reduce the need for frequent water replenishment, and reduce operation and maintenance costs. At the same time, the heating device 12 is used to achieve temperature replenishment in the morning and evening. When the temperature difference between day and night is large, heat loss at night is reduced to balance the water temperature;

[0033] Circulating water treatment system 2, circulating water treatment system 2 includes sterilization unit 21, filtration unit 22, first heating unit 23 and first oxygenation unit 24 from front end to back end. The sterilization device is ultraviolet sterilization, which is arranged at the front end of the system. Filtering unit 22 adopts activated carbon filtration. By sterilizing first and then filtering, chemical residues will not be introduced. Filtration and removal of dead bacteria and impurities, and then heating can protect heating device 12 and improve energy efficiency. Finally, oxygenation of first oxygenation unit 24 can avoid loss of dissolved oxygen due to temperature rise. At the same time, high temperature water is more likely to reach saturation after oxygenation. A water quality recheck sensor 25 is installed at the rear end of the first oxygenation unit 24. A circulating water treatment valve 26 is provided at the rear end of water quality recheck sensor 25. Sterilization unit 2 1 is connected to the front end of the circulation channel 27, and the other end of the circulation channel 27 is arranged between the water quality verification sensor 25 and the circulating water treatment valve 26. The water quality verification sensor 25 is electrically connected to the circulating water treatment valve 26. A pipeline valve is also provided inside the circulation pipeline. The circulating water treatment system 2 goes through the sequence of sterilization, filtration, heating, oxygenation and water quality testing. When the water quality verification sensor 25 detects that the water quality meets the requirements, the circulating water treatment valve 26 is opened to transport water vapor. If it does not meet the requirements, the circulating water treatment valve 26 is closed and the pipeline valve is opened. The circulating water re-flows through the circulation channel 27 for re-treatment until the water quality meets the requirements; thus, progressive regulation of water quality safety, temperature stability and sufficient dissolved oxygen is achieved.

[0034] The saline-alkali water modulation system 3 includes a salinity modulation unit 31, an alkalinity modulation unit 32, a second heating unit 33 and a second oxygenation unit 34 from the front end to the rear end. A water salinity sensor 35 is installed at the front end of the salinity modulation unit 31, and a saline-alkali water valve 36 is installed at the rear end of the second oxygenation unit 34. The water salinity sensor 35 and the saline-alkali water valve 36 are electrically connected to the salinity modulation unit 31 and the alkalinity modulation unit 32 respectively. The second oxygenation unit 34 is arranged at the end of the modulation to compensate for the dissolved oxygen loss caused by the increase in salinity and ensure the breathing needs of aquatic animals. The second heating unit 33 is heated after the alkalinity modulation to avoid high temperature exacerbating the fluctuation of ion activity in the saline-alkali solution. The salinity and alkalinity can be accurately controlled respectively through the independently arranged salinity modulation unit 31 and alkalinity modulation unit 32. The water salinity sensor 35 monitors the salinity parameters in real time and dynamically feeds back to the modulation unit to form a closed-loop control to ensure the modulation accuracy.

[0035] The circulating water treatment system 2, the saline-alkali water modulation system 3 and the pool body 1 are interconnected through the outlet pipe 4. The water flow direction is that the pool body 1 flows into the circulating water treatment system 2 for water treatment, then flows into the saline-alkali water modulation system 3 for salinity adjustment, and finally flows into the pool body 1.

[0036] For details, please refer to Figure 1 A number of spray-type water inlets 14 are provided on the top of the pool body 1, and the several spray-type water inlets 14 are connected to the saline-alkali water valve 36 through the outlet pipe 4. The spray-type water inlets 14 inject the modulated saline-alkali water into the pool body 1 in the form of fine water mist or dispersed water flow, avoiding the local excessive salinity caused by traditional single-point water inlet and reducing the stress response of aquatic animals caused by sudden changes in water quality.

[0037] For details, please refer to Figure 1 and Figure 4 , a manure leaking device 15 is connected to the lower half of the interior of the pool body 1, and a number of shelters 16 are arranged above the manure leaking device 15. The manure leaking device 15 is 8cm to 10cm away from the bottom of the pool body 1. In this embodiment, the manure leaking device 15 is 10cm away from the bottom of the pool body 1. The manure leaking device 15 is provided with a number of holes 151 with a pore diameter of 3mm to 4mm, and 7 to 14 holes per square centimeter. In this embodiment, the pore diameter of the holes 151 is 3mm, and there are 7 holes per square centimeter. The manure leaking device 15 uses a perforated PVC board. The entire manure leaking device 15 is perforated to leak residual bait and metabolites. The manure leaking device 15 is designed to be 10cm away from the bottom of the pool, forming a layered structure of the bottom sedimentation area and the upper activity area. The layered design keeps the seedling area clean and reduces the disease rate. The manure leaking device 15 is installed through the reserved slot of the pool body 1. No welding or gluing is required, which is convenient for disassembly, cleaning or replacement, and meets the maintenance needs of long-term use.

[0038] For details, please refer to Figure 1The shelter 16 is a tube body, the inner diameter of the shelter 16 tube body is 40mm~50mm, the wall thickness of the shelter 16 tube body is 2mm~3mm, and the height of the shelter 16 tube body is 8cm~10cm. In this embodiment, the inner diameter of the shelter 16 tube body is 50mm, the wall thickness of the shelter 16 tube body is 1.5mm, and the height of the shelter 16 tube body is 10cm. The shelter 16 adopts a PVC tube with an inner diameter of 50mm and a wall thickness of 1.5mm, and a height of 10cm. 9 PVC tubes are bundled to fill the manure leakage device 15. The inner diameter of the tube body is 50mm, which can provide sufficient space for activities to avoid obstruction or excessive crowding. The inner diameter of the tube body is close to the size of natural caves, providing a familiar hidden space for aquatic animals and reducing panic escape behavior in the early stage of salt-alkali acclimation.

[0039] For details, please refer to Figure 1 The upper half of the interior of the pool body 1 is connected to the limiting pipe 5, and the other end of the limiting pipe 5 is connected to the outlet pipe 4. When there is too much circulating water inside the pool body 1, the water flows through the limiting pipe 5 into the circulation pipe and then into the circulating water treatment process, avoiding excessive water inside the pool body 1 and controlling the water level height inside the pool body 1.

[0040] For details, please refer to Figure 1 A supplemental light device 6 is also installed on the top of the tank body 1, located below the spray water inlet 14. The physiological activities of many aquatic animals are affected by the light cycle. The supplemental light device 6 can simulate the diurnal variation of natural light, helping aquatic animals better adapt to the acclimation environment, reducing stress reactions caused by environmental changes, and improving their survival rate and growth performance.

[0041] For details, please refer to Figure 1 and Figure 4 A bait delivery device 7 is installed in the upper half of the interior of the pool body 1. A water outlet 41 is provided at the bottom of the pool body 1. The water outlet 41 is connected to a pipeline and is connected to a first water pump 42. The bait delivery device 7 can accurately control the amount of bait delivered to avoid excessive or insufficient feeding. Precise feeding can not only meet the growth needs of aquatic animals, but also reduce bait waste and reduce breeding costs. The water outlet 41 at the bottom of the pool body 1 is connected to the first water pump 42, which can quickly discharge the water at the bottom of the pool body 1. This design can effectively avoid the accumulation of sediments at the bottom of the pool body 1, reduce the impact of pollutants on water quality, and provide a stable water flow for the circulating water treatment system 2.

[0042] For details, please refer to Figure 1A second water pump 43 is installed on the pipeline between the saline-alkali water modulation system 3 and the several spray-type water inlets 14. The second water pump 43 is a booster pump. Through the conveying effect of the second water pump 43, the saline-alkali water can be evenly distributed to each spray-type water inlet 14. The design of multiple spray-type water inlets 14 enables the saline-alkali water to enter the pool body 1 in a dispersed manner, further promoting the mixing of the saline-alkali water and the original water body of the pool body 1, ensuring that the salinity and water quality parameters in the entire pool body 1 remain consistent, and improving the acclimation efficiency.

[0043] Specifically, a timing device 8 is installed above the outer wall of the pool body 1. The timing device 8 is electrically connected to the light-filling device 6, the bait-feeding device 7 and the water salinity sensor 35. The timing device 8 is connected to the light-filling device 6 to control the light-filling time, connected to the bait-feeding device 7 to feed at a fixed time, and connected to the water salinity sensor 35 to record the time after the salinity of the water in the pool body 1 changes, accurately controlling the time interval and duration of bait feeding, simulating the day and night changes of natural light, helping aquatic animals better adapt to the domesticated environment, and regulating their biological rhythms.

[0044] The principle of the saline-alkali adaptation and acclimation device for aquatic animals provided by the present invention is as follows:

[0045] Initial water quality measurement: The water quality and temperature sensor 13 installed in the tank body 1 monitors the parameters of the aquaculture water flowing into the circulating water system in real time;

[0046] Primary treatment: Based on monitoring data, the circulating water treatment system 2 performs physical filtration, dissolved oxygen regulation, microbial disinfection, and temperature adjustment on the aquaculture water;

[0047] Secondary detection: A water quality recheck sensor 25 is set downstream of the first heating unit 23 to recheck the water quality indicators of the treated aquaculture water;

[0048] Circulation control: When the water quality does not meet the preset aquaculture standards, the circulating water treatment valve 26 is closed to return the water to the primary treatment link for reprocessing;

[0049] Salt-alkali modulation: When the water quality is verified to be up to standard, the circulating water treatment valve 26 is opened, the salinity sensor is used to monitor the water body in real time, and the salt water modulation device and the alkaline water modulation device are controlled to release the powdered regulator according to the preset ratio;

[0050] Water reuse: The treated water that meets the standards is transported to the spraying water outlet device through the second water pump 43 to complete the aquaculture water circulation process.

[0051] In summary, the present invention uses the circulating water treatment system 2 and the saline-alkali water modulation system 3 to undertake the functions of impurity removal, oxygenation and gradual increase of salinity, thereby gradually increasing the salinity of the aquaculture water in the pond and achieving the purpose of acclimating aquatic animals in the pond.

[0052] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
