[0033] A device for improving the survival rate of yellowfin sea bream seedlings cultured in saline-alkali land during transportation, comprising a water tank 1 and a top cover 4 installed at the upper end of the water tank 1;

[0034] A partition 9 is fixedly connected to the interior of the water tank 1;

[0035] The right end outer wall of the partition 9 is fixedly connected with an oxygen pump 8;

[0036] The lower end outer wall of the oxygen pump 8 is fixedly connected with a plurality of air delivery pipes 10, and the other ends of the plurality of air delivery pipes 10 are fixedly connected with an aeration head 11 to eject air from the inside of the water tank 1. A drain port 16 is provided on the left end outer wall of the water tank 1 for draining the water in the water tank 1. The inner thread of the drain port 16 is connected with a fixed plug 15 to close the drain port 16. When transporting yellowfin bream seedlings for breeding in saline-alkali land, the top cover 4 is first opened, the saline-alkali land water is placed in the water tank 1, and the yellowfin bream seedlings are transferred to the water tank 1 after being heated and watered. Inside the box 1, the oxygen pump 8 is started at the same time. After the oxygen pump 8 inhales air, it is sprayed from the aeration head 11 into the water body inside the water tank 1 through the guidance of the air supply pipe 10 to supply oxygen to the yellowfin porgy fry, and the top cover 4 is closed. After reaching the saline-alkali land breeding pond, the fixing plug 15 is unscrewed counterclockwise to open the drain port 16, and the water body together with the yellowfin porgy fry is discharged into the saline-alkali land breeding pond. Then the top cover 4 is opened to clean the inside of the water tank 1. After the cleaning is completed, the fixing plug 15 is screwed back clockwise and the top cover 4 is fixed;

[0037] A plurality of spoilers 14 are arranged equidistantly from left to right inside the water tank 1 to reduce the shaking amplitude of the water body in the water tank 1. A through-hole 13 is opened at the center of the plurality of spoilers 14 to allow water to flow. When transporting yellowfin sea bream fry, a plurality of spoilers 14 are added inside the water tank 1 to reduce the shaking amplitude of the water body inside the water tank 1, reduce the influence of the water shaking on the yellowfin sea bream fry, and maintain the circulation of the water body through the opened through-hole 13.

[0038] Please refer to Figure 2 and Figure 3 A plurality of limit grooves 17 are provided on the inner walls at both ends of the water tank 1 to limit the positions of the plurality of spoilers 14. A connecting rod 12 is fixedly connected between the upper outer walls of the plurality of spoilers 14. A handle 7 is fixedly connected to the upper outer wall of the connecting rod 12 to drive the spoiler 14 to move up and down inside the limit groove 17 under the action of external force. Magnetic blocks b19 are embedded inside the plurality of spoilers 14 and near the upper and lower sides respectively.

[0039] When it is necessary to discharge the yellowfin sea bream fry, the handle 7 is grasped to make the connecting rod 12 drive the multiple spoilers 14 to move upward inside the limiting groove 17. When the multiple spoilers 14 move to the uppermost side of the limiting groove 17, magnetic attraction is performed between the magnetic block b19 and the magnetic block a18 to limit the position of the spoiler 14, so that the lower side of the spoiler 14 cannot prevent the water from driving the movement of the yellowfin sea bream fry during the discharge process.

[0040] Please refer to Figure 3 and Figure 4 Magnetic blocks a18 are embedded in the water tank 1 and are located on the upper and lower sides of the limiting groove 17 to magnetically attract and adsorb with the magnetic block b19 to limit the position of the spoiler 14. The plurality of spoilers 14 are made of polyethylene plastic material.

[0041] At the same time, the connecting rod 12 can be pressed down to allow the magnetic block b19 and the magnetic block a18 on the lower side of the spoiler 14 to be magnetically attracted to each other, thereby preventing the spoiler 14 from shaking during transportation.

[0042] Please refer to Figure 5 and Figure 6 An observation port 6 with upper and lower openings is provided inside the upper outer wall of the top cover 4 to observe the state of the yellowfin sea bream fry inside the water tank 1, and a baffle 21 is provided on the lower side of the observation port 6. The upper inner wall of the top cover 4 and the front and rear sides of the observation port 6 are fixedly connected with slide rails 20 to limit the position of the baffle 21, and a fixing hole a22 that passes through from top to bottom is provided inside the upper outer wall of the baffle 21. A fixing hole b23 that opens upward is provided between the upper outer wall of the baffle 21 and the inside of the top cover 4, and the fixing hole a22 and the fixing hole b23 have the same lateral lengths, and a plug rod 24 is inserted into the fixing hole b23 to limit the position of the baffle 21, and a fixing plate 25 is fixedly connected to the upper outer wall of the plug rod 24.

[0043] During the transportation of yellowfin sea bream fry, the fixing plate 25 can be lifted up, and then the insertion rod 24 at the lower end of the fixing plate 25 can be inserted into the fixing hole a22 on the baffle 21. Then, the fixing plate 25 can be moved to the left to drive the baffle 21 to move to the left under the restriction of the slide rail 20, and the observation port 6 can be exposed. At this time, the survival status of the yellowfin sea bream fry in the water tank 1 can be observed through the observation port 6, and fish food can be fed. At the same time, the air inside the water tank 1 can be circulated. After the observation is completed, the baffle 21 is driven to move to the right, and then the fixing plate 25 is pulled out. The insertion rod 24 is inserted downward into the fixing hole b23 to limit the position of the baffle 21 and cover the observation port 6.

[0044] Please refer to Figure 1 and Figure 2 The upper outer wall of the top cover 4 is equidistantly provided with a plurality of fixing screws 5 penetrating downward into the water tank 1 to limit the position of the top cover 4, and handles 3 are embedded in the left and right outer walls of the water tank 1 to drive the water tank 1 to move under the action of external force, and a power interface 2 is embedded in the right outer wall of the water tank 1 to supply power to the oxygen pump 8 by plugging in a power cord, and a vent is opened in the upper outer wall of the top cover 4 for the oxygen pump 8 to inhale air.

[0045] When installing the top cover 4, the top cover 4 and the water tank 1 can be fixedly connected by screwing the fixing screws 5 into the top cover 4 and the inside of the water tank 1. When moving the water tank 1, the water tank 1 can be moved by buckling the handle 3. When the oxygen pump 8 is working, the oxygen pump 8 can be started by inserting the power cord into the power interface 2. During the operation, air is sucked in from the outside of the water tank 1 through the vent and transported to the inside of the water tank 1.

[0046] The implementation principle of this embodiment is as follows: when transporting yellowfin porgy fry for breeding in saline-alkali land, first open the top cover 4, put the saline-alkali land water into the water tank 1, and transfer the yellowfin porgy fry to the inside of the water tank 1 after superheating and water treatment, and start the aerator 8 at the same time. After the aerator 8 inhales air, it is sprayed from the aeration head 11 to the water inside the water tank 1 through the guidance of the air supply pipe 10 to supply oxygen to the yellowfin porgy fry, and close the top cover 4. After arriving at the saline-alkali land breeding pond, unscrew the fixing plug 15 counterclockwise to open the drain port 16, and discharge the water connected with the yellowfin porgy fry into the saline-alkali land breeding pond together, then open the top cover 4, clean the inside of the water tank 1, and after cleaning, screw back the fixing plug 15 clockwise and then fix the top cover 4. When transporting the yellowfin porgy fry, a plurality of spoilers 14 are added to the inside of the water tank 1 to reduce the amplitude of the water shaking inside the water tank 1, reduce the influence of the water shaking on the yellowfin porgy fry, and keep the water flowing through the opened opening 13.
