[0004] When the above patent is used, the water in the water area is first pumped into the box and the buffer bucket, and then the aquatic seedlings are put into the box, so that the aquatic seedlings are in contact with the water in the water area in advance, and then the aquatic seedlings and the water are flowed from the release pipe to the water area where they need to be released. In this way, the aquatic seedlings proliferation and release work can be completed. However, during the release process, if the weather is sunny, the aquatic seedlings and water in the box are easily exposed to direct sunlight, and then the water temperature in the box gradually rises, which causes the temperature of the environment where the aquatic seedlings are located to change drastically, and the aquatic seedlings are easily killed by the temperature stimulation, so the survival rate of the aquatic seedlings is low.

The shielding mechanism 3 can block sunlight from the inside of the box body 1.

[0043] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the closing mechanism 2 includes a water retaining plate 27, a rotating screw 28, a handle 29 and a discharge assembly. The rotating screw 28 is rotatably connected to the lower right portion of the box body 1, the handle 29 is fixed to the right side of the rotating screw 28, the water retaining plate 27 is threadedly connected to the rotating screw 28, the water retaining plate 27 is located inside the box body 1, and the water retaining plate 27 is slidably connected to the box body 1, and the discharge assembly is arranged at the upper right portion of the box body 1.

[0044] like Figure 4 , Figure 5 and Figure 6 As shown, the discharge assembly includes a water blocking frame 21, a drain pipe 22, a return spring 23, a rising rod 24, an air bag 25 and a filter screen 26. The water blocking frame 21 is slidably connected to the upper right part of the box body 1, the return spring 23 is connected between the water blocking frame 21 and the upper right side of the box body 1, the drain pipe 22 is connected to the upper right side of the box body 1, the drain pipe 22 is communicated with the box body 1, the filter screen 26 is connected to the upper side of the right wall inside the box body 1, the rising rod 24 is slidably connected to the right wall inside the box body 1, the rising rod 24 is squeezed and matched with the water blocking frame 21, and the air bag 25 is connected to the lower side of the rising rod 24.

[0045] like Figure 1 , Figure 8 , Fig. 9 and Fig.10 As shown, the shielding mechanism 3 includes a fixed seat 31, a shielding cover 32, a return torsion spring 33, a limit frame 34 and an extrusion spring 35. The fixed seat 31 is connected to the upper front part of the box body 1, the shielding cover 32 is rotatably connected to the fixed seat 31, the return torsion spring 33 is connected between the lower left side of the shielding cover 32 and the fixed seat 31, the return torsion spring 33 is wound on the fixed seat 31, the limit frame 34 is slidably connected to the upper right front side of the box body 1, the left part of the limit frame 34 is inserted into the shielding cover 32, the lower side of the right rear part of the limit frame 34 is an inclined surface, the rear part of the limit frame 34 and the top of the rising rod 24 are squeezed together, and the extrusion spring 35 is connected between the limit frame 34 and the box body 1.

[0046] Initially, the reset torsion spring 33 is in a torsion state. When the aquatic seedling proliferation and release buffer device is used, the aquatic seedling proliferation and release buffer device is first placed on the shore of the water area, and the right part of the release tube 12 is above the water. Then, the limit screw 13 is manually rotated so that the limit screw 13 no longer abuts against the support foot 11. At this time, the box body 1 will move downward under its own gravity, and then drive the release tube 12 to move downward, so that the release tube 12 is close to the water surface. When the release tube 12 is close to the water surface, the box body 1 is controlled to stop moving downward, and then the limit screw 13 is manually rotated in the opposite direction so that the limit screw 13 abuts against the support foot 11. Then, the handle 29 is manually rotated, and then the rotating screw 28 is driven to rotate, driving The movable water retaining plate 27 moves to the left, so that the water retaining plate 27 closes the lower part of the box body 1, and then the external water pump is connected to the water spraying member 14, and the external water pump is turned on. At this time, the external water pump will transport the water in the water area to the water spraying member 14, and then the water spraying member 14 will spray the water into the inside of the box body 1. When the water in the box body 1 reaches a third of the position, the aquatic seedlings are put into the box body 1. At this time, the aquatic seedlings will swim in the water in the box body 1, so that the aquatic seedlings can first contact with the water in the water area and adapt to the growth environment in advance. As the water in the box body 1 gradually increases and the water level slowly rises, the air bag 25 will also drive the rising rod 24 to move upward. When the rising rod 24 moves upward and contacts with the water blocking frame 21, the rising rod 24 will move the water blocking frame 21 upward When the water level rises to the filter screen 26, the water will flow into the drain pipe 22 through the filter screen 26, and then flow into the water area from the lower right side of the drain pipe 22, so that the water in the box body 1 can flow, thereby improving the effect of aquatic seedlings adapting to the environment. At the same time, when the rising rod 24 moves upward and contacts the limit frame 34, the rising rod 24 will push the limit frame 34 forward, so that the limit frame 34 no longer limits the shielding cover 32, and the extrusion spring 35 is stretched. At this time, under the action of the reset torsion spring 33, the shielding cover 32 will rotate to cover the inside of the box body 1, so that the water in the box body 1 can be prevented from being directly exposed to the sun, resulting in a linear temperature rise. Rising to prevent the temperature of the growth environment of aquatic seedlings from changing dramatically. After the aquatic seedlings have been soaked for twenty to thirty minutes, it means that the time for the aquatic seedlings to adapt to the environment is over. At this time, people can manually reverse the shielding cover 32 by ninety degrees, and then the reset torsion spring 33 is twisted, and then manually rotate the rotating screw 28 and the handle 29 in the opposite direction, and then drive the water retaining plate 27 to move to the right to open the lower part of the box body 1. At this time, the water and aquatic seedlings in the box body 1 will flow into the water area through the discharge pipe 12, so that the aquatic seedlings can be discharged. And because the discharge pipe 12 is close to the water surface, it can buffer the aquatic seedlings during the discharge process to prevent the aquatic seedlings from being impacted by the water body and prevent the aquatic seedlings from being damaged, thereby improving the survival rate of the aquatic seedlings.At the same time, when the water level in the box body 1 of the aquatic seedlings slowly drops, the rising rod 24 and the airbag 25 will also move downward under their own gravity. When the rising rod 24 moves downward and no longer squeezes the limiting frame 34, under the action of the squeezing spring 35, the limiting frame 34 moves backward to limit the shielding cover 32, and then people can release their hands without having to hold the shielding cover 32 all the time. At the same time, when the rising rod 24 moves downward and no longer squeezes the water blocking frame 21, under the action of the reset spring 23, the water blocking frame 21 moves downward to close the connection between the box body 1 and the drain pipe 22. After all the aquatic seedlings are released, the external water pump is turned off, and then the limiting screw 13 is turned to unlock the box body 1, and then the box body 1 and the drain pipe 12 are manually lifted up. When the box body 1 and the drain pipe 12 move upward and reset, the limiting screw 13 is manually rotated in the opposite direction. In summary, the aquatic seedlings can be proliferated and released, and the death of the aquatic seedlings can be avoided during the release process.

[0047] Example 2

[0048] On the basis of Example 1, Figure 1 , Figure 2 , Fig.11 , Fig.12 and Fig.13 As shown, an extension mechanism 4 is also included, and the extension mechanism 4 includes an extension tube 41, a threaded rod 42, a drive motor 43, a movable frame 44 and a rotating frame 45. The drive motor 43 is installed on the upper right side of the discharge tube 12, and the threaded rod 42 is connected to the output shaft of the drive motor 43 through a coupling. The extension tube 41 is threadedly connected to the threaded rod 42, and the extension tube 41 is slidingly connected to the discharge tube 12. There are two rotating frames 45, and the two rotating frames 45 are rotatably connected to the front and rear sides of the right part of the extension tube 41 through damping sleeves respectively, and the movable frame 44 is connected between the lower parts of the two rotating frames 45.

[0049] When people release aquatic seedlings and need to keep them away from the shore, they can use the extension mechanism 4 to operate. When the aquatic seedling proliferation and release buffer device is placed on the shore of the water area, the lower right part of the mobile frame 44 will extend into the water. Then, when people release aquatic seedlings, the aquatic seedlings will flow into the water area through the extension tube 41 and the mobile frame 44. In this way, the aquatic seedlings can be buffered to avoid the large impact force of the aquatic seedlings falling into the water area. In addition, people can adjust the angle of the aquatic seedlings released into the water by rotating the mobile frame 44 and the rotating frame 45. When people release the aquatic seedlings, they need to keep the aquatic seedlings away from the shore. When the aquatic seedlings are released, the output shaft of the driving motor 43 is controlled to drive the threaded rod 42 to rotate in the opposite direction, and then the extension tube 41 is driven to drive the moving frame 44 and the rotating frame 45 to move to the left. In summary, the aquatic seedlings can be buffered during the releasing process, and the distance between the aquatic seedlings and the water bank can also be increased to prevent the aquatic seedlings from being washed to the water bank by waves and colliding with the water bank.

[0050] like Figure 1 , Figure 2 , Fig.14 , Fig.15 and Fig.16 As shown, it also includes a dispersion mechanism 5, which includes a dispersion frame 51, a rotating screw 52, ​​a fixed frame 53, a lower pressure frame 54 and a linear spring 55. The fixed frame 53 is connected to the upper side of the front wall inside the box body 1, the lower pressure frame 54 is slidably connected to the left rear part of the fixed frame 53, the linear spring 55 is connected between the lower pressure frame 54 and the fixed frame 53, the linear spring 55 is wound on the lower pressure frame 54, the rotating screw 52 is rotatably connected to the rear part of the fixed frame 53, the rotating screw 52 is slidably extruded with the lower part of the lower pressure frame 54, and the dispersion frame 51 is connected to the lower side of the rotating screw 52.

[0051] When the aquatic seedlings are adapting to the environment in the box 1, if it is necessary to prevent the aquatic seedlings from gathering in the box 1, the dispersion mechanism 5 can be used to operate it. The lower pressure frame 54 can be pressed downward manually, and the linear spring 55 will be compressed. At this time, the lower pressure frame 54 will drive the rotating screw 52 to rotate, and then the rotating screw 52 will drive the dispersion frame 51 to rotate, so as to disperse the aquatic seedlings that are clustered together. Then the lower pressure frame 54 is released. At this time, under the action of the linear spring 55, the lower pressure frame 54 moves upward, and the lower pressure frame 54 will drive the rotating screw 52 to drive the dispersion frame 51 to rotate in the opposite direction. In summary, the aquatic seedlings that are clustered together can be dispersed.

[0052] like Figure 1 , Figure 2 , Fig.17 and Fig.18 As shown, a detection mechanism 6 is also included, and the detection mechanism 6 includes an oxygen detection sensor 61, a servo motor 62 and a rotating rod 63. The oxygen detection sensor 61 is connected to the upper left front side of the box body 1 in a through-type manner, and the servo motor 62 is installed on the left front side of the box body 1. The servo motor 62 is located below the oxygen detection sensor 61. The servo motor 62 is electrically connected to the oxygen detection sensor 61. The rotating rod 63 is connected to the output shaft of the servo motor 62, and the rotating rod 63 is red.

[0053] When the aquatic seedlings are immersed in the box 1 to adapt to the environment, in order to avoid people not noticing the lack of oxygen in the box 1, the detection mechanism 6 can be used for operation. When the aquatic seedlings are immersed in the box 1 to adapt to the environment, the oxygen detection sensor 61 will detect the oxygen in the water inside the box 1. When the oxygen detection sensor 61 detects that the oxygen in the water is insufficient, the oxygen detection sensor 61 will turn on the servo motor 62 and control the output shaft of the servo motor 62 to rotate, so that the output shaft of the servo motor 62 drives the rotating rod 63 to rotate, so that the people around can be reminded that the oxygen in the box 1 is insufficient and please add oxygen to the box 1 in time. At this time, people can open the shielding cover 32 by rotating it and add oxygen to the box 1 with the help of an external oxygen supplier. When people finish adding oxygen, the oxygen detection sensor 61 detects that the oxygen in the water returns to normal, and the oxygen detection sensor 61 will turn off the servo motor 62. In summary, when the aquatic seedlings are immersed in the box 1 to adapt to the environment, the oxygen value inside the box 1 can be detected in real time.

[0054] As 2, Fig.19 and Fig. 20 As shown, a cleaning mechanism 7 is also included, which includes a cleaning brush 71 and a return torsion spring 72. The cleaning brush 71 is rotatably connected to the front upper side of the right inner wall of the box body 1, and the cleaning brush 71 is located in front of the filter screen 26. The return torsion spring 72 is connected between the cleaning brush 71 and the box body 1, and the return torsion spring 72 is wound around the box body 1.

[0055] After the filter 26 has been used for a period of time, the filter 26 may be clogged with scale or other impurities. In order to avoid this phenomenon, the cleaning mechanism 7 can be used to clean the filter 26. The cleaning brush 71 can be manually rotated backward, and the return torsion spring 72 can be twisted. Then the cleaning brush 71 can be released. Under the action of the return torsion spring 72, the cleaning brush 71 rotates forward. When the cleaning brush 71 rotates and passes through the filter 26, the cleaning brush 71 can clean the impurities or scale attached to the filter 26. In summary, the filter 26 can be cleaned to avoid the filter 26 being blocked.
