[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1 , Figure 2 , Figure 3This utility model provides an embodiment of a shrimp larvae desalination device, comprising: a shrimp larvae desalination tank 1, a partition 102 disposed in the middle of the shrimp larvae desalination tank 1, a platform 101 disposed above the partition 102, a supply component 6 installed above the platform 101, the supply component 6 including a supply tank 601, a test chamber 105 and a cultivation chamber 106 respectively disposed on both sides of the partition 102, an inlet 103 and an outlet 104 disposed on the outer walls of both the front and rear ends of the test chamber 105 and the cultivation chamber 106, a monitoring component 5 for monitoring water quality changes installed in both the test chamber 105 and the cultivation chamber 106, and a desalination dilution tank 2 connected to one side of the supply tank 601 via a pipeline, the desalination dilution tank 2 having a stirring component 3 installed inside, and the device connected to the partition 102 via the partition 102. The setup 2 divides the shrimp larvae desalination tank 1 into two parts: an experimental chamber 105 and a rearing chamber 106. During the desalination process, the salinity is first adjusted and diluted by the desalination dilution tank 2, and then the liquid is sent into the supply component 6. The supply component 6 first sends the liquid into the experimental chamber 105, and the monitoring component 5 in the experimental chamber 105 monitors the water quality changes. The user repeatedly adjusts the salinity according to the water quality changes until the required salinity is reached. Then, the diluent in the supply component 6 is added to the rearing chamber 106. This allows the equipment to reasonably adjust the salinity changes according to the shrimp larvae desalination requirements and repeatedly adjust the concentration of the diluent according to the addition of diluent. Finally, it is added to the rearing chamber 106 to ensure that the correct diluent is added to the rearing chamber 106 to promote the desalination of the shrimp larvae.

[0024] Among them, such as Figure 2 , Figure 4 As shown, a salt addition pipe 201 and a water addition pipe 202 are installed on the outer wall of the desalination and dilution tank 2. A delivery pipe 203 is provided between the desalination and dilution tank 2 and the supply storage tank 601. The stirring assembly 3 includes a motor 301 installed on the upper surface of the desalination and dilution tank 2. A stirring rod 302 extending into the tank is installed at the output end of the motor 301. Several stirring blades 303 are installed on the outer wall of the stirring rod 302. A first salinity sensor 4 for monitoring changes in salinity inside the tank is installed on the upper surface of the desalination and dilution tank 2. The salt addition pipe 201 and the water addition pipe 202 are used to deliver liquid and water into the desalination and dilution tank 2, respectively. The motor 301 drives the stirring rod 302 and the stirring blades 303 to rotate, mixing the salt in the desalination and dilution tank 2 into the liquid. During this process, the first salinity sensor 4 monitors changes in salinity, and the diluted liquid is pumped into the supply storage tank 601 through the delivery pipe 203. The above structure can pre-treat the salinity of the water in the early stage of desalination, accelerate the mixing efficiency of salt and liquid by stirring, and improve the mixing uniformity. The first salinity sensor 4 monitors the salinity change in real time, and finally sends the saline liquid to the supply component 6 for subsequent supply operations.

[0025] Please seeFigure 1 , Figure 2 The monitoring component 5 includes an assembly frame 501. Temperature sensors 502, a second salinity sensor 503, a pH sensor 504, and a dissolved oxygen sensor 505 are arranged at intervals on the outer wall of the assembly frame 501. A PLC controller 107 is installed on the outer wall of the shrimp larvae desalination tank 1. The input terminal of the PLC controller 107 is electrically connected to the output terminals of the temperature sensors 502, the second salinity sensor 503, the pH sensor 504, and the dissolved oxygen sensor 505. The monitoring component 5 is used to monitor the water quality in the test chamber 105 and the cultivation chamber 106. By setting the temperature sensors 502, the second salinity sensor 503, the pH sensor 504, and the dissolved oxygen sensor 505, the temperature, salinity, pH value, and dissolved oxygen status of the water in the two chambers can be monitored. The monitored data is fed back to the PLC controller 107, which allows users to obtain the corresponding monitoring data in real time. This allows users to subsequently change the temperature, salinity, pH value, dissolved oxygen, and other conditions of the water based on the obtained water quality data.

[0026] Please see Figure 3 The supply tank 601 has a delivery pump 602 connected to both sides of its outer wall via pipelines. The discharge end of the delivery pump 602 is equipped with a discharge pipe 603, and several horizontally spaced discharge outlets 604 are installed below the discharge pipe 603. The supply tank 601 is provided with discharge pipes 603 facing the test chamber 105 and the cultivation chamber 106 respectively. The diluent is first sent into the discharge pipe 603 facing the test chamber 105 by the delivery pump 602, and then falls into the test chamber 105 through the discharge outlets 604. This is used to test the desalination process of shrimp larvae by changing the salinity of the water. By repeating the above test process, the required salt concentration of the shrimp larvae is obtained. Then, the diluent of the corresponding concentration is sent into the cultivation chamber 106 to desalinate the shrimp larvae. The above structure avoids the irreversible situation that would affect the cultivation of shrimp larvae by directly introducing salt into the shrimp larvae cultivation chamber 106, and ensures that the appropriate desalination concentration can be obtained at different stages of the shrimp larvae cultivation process.
