[0002] Shrimp larvae breeding requires extremely high water salinity and alkalinity, but saline-alkali ponds generally have problems with high salinity and excessive pH, which directly affects the survival rate of shrimp larvae.

[0003] In the prior art, CN207707080U discloses a device for aquaculture, including a culture pond, a pH monitoring device, and a pH adjustment device. The pH monitoring device is installed on the culture pond, and the pH adjustment device is installed inside the culture pond. The pH adjustment device includes an acid adjustment tank, an alkaline adjustment tank, an acid adjustment tube, an alkaline adjustment tube, a neutralization tank, and a pH detector. The acid adjustment tank and the alkaline adjustment tank are respectively installed on one side of the top of the culture pond. However, the area of ​​the pond is usually relatively large, and the content of suspended solids and ammonia nitrogen in the water is not the same in all areas. Relying on manual uniform spraying of drugs or establishing drug application points in the pond cannot achieve corresponding increases in the dosage in areas with high suspended solids or ammonia nitrogen content. Moreover, the drug addition and water flow are not evenly mixed when adding drugs, which can easily lead to excessively high drug concentrations in local water bodies, causing stress damage to shrimp larvae. Summary of the Invention

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] Example 1 like Figures 1 to 6 As shown, a saline-alkali pond desalination and alkali improvement facility suitable for shrimp fry breeding includes a hull 1, and a feeding mechanism 2 is provided on the top of the hull 1. The feeding mechanism 2 includes a water guide pipe 21 fixed to the bottom of the hull 1. A medicine storage tank 22 is fixed inside the hull 1. A flow control valve 26 is symmetrically fixed to the bottom of the medicine storage tank 22. A medicine dispensing pipe 25 is installed on the surface of the flow control valve 26. A rotating shaft 210 is rotatably connected inside the water guide pipe 21 via a mounting bracket. Several sets of stirring rods 211 are fixedly installed on the surface of the rotating shaft 210. An axial flow blade 29 is connected to the front end of the rotating shaft 210. A driving mechanism is installed inside the water guide pipe 21, which can drive the rotating shaft 210 to rotate. The rotation of the axial flow blade 29 generates negative pressure, which efficiently draws in the saline water of the pond. The stirring rods 211 rotate synchronously with the rotating shaft 210, which quickly achieves shear mixing of the medicine and the water. The overall structure, through the coordinated operation of components such as the water guide pipe 21 and the medicine storage tank 22, provides a uniform and improved aquatic environment for shrimp larvae breeding.

[0019] Furthermore, the medicine storage tank 22 is internally fixed with a partition 212, which divides the interior of the partition 212 into two cavities. The two cavities are respectively connected to the interior of the water guide pipe 21 through two sets of flow control valves 26. The dual-cavity design of the medicine storage tank 22 can independently store desalination agents and alkali-improving agents, avoiding the ineffectiveness of mixing different agents. With the independent flow control valves 26, the precise dosing of the two types of agents can be achieved. Through the connection between the medicine supply pipe 25 and the water guide pipe 21, the coordinated control of desalination and alkali-improving functions can be supported, adapting to complex water quality requirements.

[0020] A water quality monitor 27 is installed inside the hull 1. A monitoring probe 28 is fixed to the bottom of the water quality monitor 27, and the bottom of the monitoring probe 28 penetrates the hull 1 and extends into the water guide pipe 21. The water quality monitor 27 and the drug delivery pipe 25 are electrically connected. The monitoring probe 28 captures the salinity and pH data of the water in the water guide pipe 21 in real time. The water quality monitor 27 automatically controls the opening state of the flow control valve 26 through data comparison and analysis. It precisely adjusts the opening of the flow control valve 26 to automate the drug delivery. This ensures that the water parameters are stable and meet the requirements for shrimp fry breeding, and guarantees the effectiveness of the drug delivery in the drug storage tank 22.

[0021] The rear end of the water guiding pipe 21 is connected to a diversion pipe 24. The surface of the diversion pipe 24 is provided with several drainage outlets. The multi-drainage outlet design of the diversion pipe 24 enables the improved water to be discharged uniformly from multiple angles and over a large area; avoids excessively high concentrations of medicine in local water bodies, which can cause stress damage to shrimp larvae; accelerates the diffusion speed of the improved water in the pond; and, in conjunction with the water conveyance function of the water guiding pipe 21, improves the overall water quality regulation efficiency of the pond.

[0022] Example 2 Improvements based on Example 1: A filtration mechanism 3 is provided at the front end of the water guide pipe 21. The filtration mechanism 3 includes a filter screen 32 with a conical structure that is fixedly connected to the front end of the water guide pipe 21. The conical structure of the filter screen 32 increases the filtration contact area and improves the interception efficiency; it effectively filters plankton, impurities and shrimp larvae predators in the water; it prevents the water guide pipe 21, stirring rod 211 and other internal components from clogging; and it ensures the long-term stable operation of the feeding mechanism 2.

[0023] The front end of the filter screen 32 is rotatably connected to a cleaning brush 31 that matches the shape of its conical mesh body. The cleaning brush 31 is connected to the rotating shaft 210. The cleaning brush 31 rotates synchronously with the rotating shaft 210, continuously scraping the surface of the filter screen 32. This promptly removes attached impurities, preventing the filter screen 32 from becoming clogged and causing a decrease in water flow. It eliminates the need for frequent manual cleaning, reducing the maintenance cost of the filtration mechanism 3. It also ensures that the water inlet channel of the water guide pipe 21 is unobstructed, maintaining the operating efficiency of the facility.

[0024] Furthermore, a drug mixing mechanism 4 is provided on the surface of the drug storage tank 22. A stirring shaft 41 is rotatably connected inside the drug mixing mechanism 4. A drive motor 42 for driving the stirring shaft 41 to rotate is installed on the surface of the drug storage tank 22. The drive motor 42 drives the stirring shaft 41 to rotate continuously, preventing the drug in the drug storage tank 22 from settling and separating; ensuring uniform drug concentration, ensuring stable drug effect each time it is added through the drug delivery pipe 25; and improving the reliability and repeatability of salt reduction and alkali improvement.

[0025] The bottom of the medicine storage tank 22 is designed with an arc shape to reduce the amount of medicine residue in the medicine storage tank 22 and improve the utilization rate of medicine; the arc shape guides the medicine to flow smoothly to the flow control valve 26 and avoids accumulation at the bottom of the tank.

[0026] Working Principle: When in use, the facility is placed in a shrimp larvae breeding pond. The hull 1 floats on the water surface and can move to different areas of the pond via an automatic cruise system. Salt-reducing and alkali-modifying agents are added to the two chambers of the medicine storage tank 22 in the feeding mechanism 2, respectively. After adding the agents through the medicine inlet 23, the tank is sealed. The drive motor 42 in the medicine mixing mechanism 4 is activated, driving the stirring shaft 41 inside the medicine storage tank 22 to rotate, preventing agent sedimentation and ensuring uniform agent concentration. The drive mechanism of the rotating shaft 210 is activated, causing the axial flow blades 29 at the front end to rotate at high speed, generating negative pressure suction to draw the saline water from the pond through the front end of the water inlet pipe 21. The water first passes through the filter screen 32 in the conical filter mechanism 3, which intercepts plankton and impurities. Simultaneously, the rotating shaft 210 drives the cleaning brush 31 connected to it to rotate, and the cleaning brush 31 and the filter screen 32 are tightly fitted together. The water, tightly fitted and continuously scraped by the rotating shaft 210 against the filter screen 32, removes the attached impurities. The water entering the water guide pipe 21 flows through the monitoring probe 28 area of ​​the water quality monitor 27. The monitoring probe 28 detects the salinity and pH value of the water in real time and transmits the data to the water quality monitor 27 inside the hull 1. The water quality monitor 27 controls the opening and adjusts the opening degree of two sets of flow control valves 26 according to the salinity. After the agent is injected into the water guide pipe 21 through the drug delivery pipe 25, multiple sets of stirring rods 211 on the surface of the rotating shaft 210 rotate at high speed with the shaft, shearing and stirring the water flow and the agent. The turbulence effect of the stirring rods 211 makes the agent and the water fully mixed. The mixed and improved water flows through the diversion pipe 24 at the rear end of the water guide pipe 21 and is evenly discharged into the pond at multiple angles and over a large area through multiple drainage outlets evenly distributed on the surface of the diversion pipe 24, ensuring that the improved water quickly spreads to the working area.
