[0002] With the development of the aquaculture industry, the temporary culture of crab seedlings has become an important link in the farming process. As a commonly used temporary culture tool, the crab seedling temporary culture tank provides a relatively independent and controllable growth environment for crab seedlings, which helps to improve the survival rate and growth rate of crab seedlings.

[0003] Crab seedlings have different requirements for the water environment at different growth stages, such as water temperature, dissolved oxygen content, water flow rate, etc. Among them, the water depth is also an important influencing factor, and the suitable water depth range for crab seedlings of different specifications also varies. During the farming process of crab seedlings, farmers need to flexibly adjust the height of the crab seedling temporary culture tank in the water according to various factors such as the growth status of crab seedlings, weather changes, and water quality conditions to optimize the growth environment of crab seedlings. However, the height adjustment function of the current crab seedling temporary culture tank is not perfect enough, and it is very difficult to adjust its height in the water according to the farming needs of farmers. This not only brings inconvenience to the operation of farmers, but also is difficult to meet the best requirements of crab seedlings for water depth at different growth stages, thereby affecting the growth performance and farming benefits of crab seedlings.

At this time, the crab seedlings can be temporarily cultured through the temporary culture box 3. When it is necessary to adjust the height of the temporary culture box 3 in the water body, the limiting sleeve 5 can be rotated. Through the threaded cooperation between the limiting sleeve 5 and the support column 4, the limiting sleeve 5 is driven to perform a vertical displacement. When the limiting sleeve 5 is separated from the floating platform 1, the floating platform 1 can be pulled to drive the temporary culture box 3 inside the floating platform 1 to perform a vertical displacement. At this time, the height of the temporary culture box 3 in the water body can be adjusted. After adjusting the corresponding height of the temporary culture box 3, the limiting sleeve 5 is rotated to drive the limiting sleeve 5 to perform a vertical displacement. When the limiting sleeve 5 contacts the floating platform 1, the corresponding positions of the floating platform 1 and the temporary culture box 3 are fixed at this time. When the breeding personnel are using the three-dimensional crab seedling temporary culture tank, if it is not necessary to adjust the corresponding height of the floating platform 1 and it is necessary to adjust the corresponding height of the temporary culture box 3, the connecting column 6 can be rotated to drive the first gear 7 to rotate.

At this time, the corresponding height of the temporary culture box 3 can be adjusted. When the breeding personnel need to remove the temporary culture box 3 in the floating platform 1 from the floating platform 1 for maintenance and repair of the temporary culture box 3, through the displacement of the connecting plate 9, the connecting block 10 and the first rack plate 8 are driven to displace. When the first rack plate 8 is separated from the first gear 7, the temporary culture box 3 can be pulled. Through the cooperation between the temporary culture box 3 and the installation groove 2, the temporary culture box 3 is driven to perform a vertical displacement. When the temporary culture box 3 is separated from the inside of the installation groove 2, the temporary culture box 3 is removed from the floating platform 1 at this time.

Through the water inlet holes, the water liquid in the aquaculture water body will enter the inside of the temporary culture box 3.

[0032] Both ends of the temporary holding box 3 are provided with support blocks 34 fixed to the top side of the floating platform 1, and the connecting column 6 located on one side of the floating platform 1 is rotatably connected between the two support blocks 34, and one end of the connecting column 6 located on the other side of the floating platform 1 is rotatably connected to the support block 34 at one end of the floating platform 1, and the other end of the connecting column 6 located on the other side of the floating platform 1 passes through the support block 34 at the other end of the floating platform 1 and is fixed with a handle 35. The outer walls of the connecting columns 6 are fixedly sleeved with a transmission wheel, and the outside of the transmission wheel is provided with a transmission belt that cooperates with the transmission wheel. By rotating the handle 35, the connecting column 6 on the other side of the floating platform 1 can be driven to rotate. When the connecting column 6 on the other side of the floating platform 1 rotates, the transmission cooperation between the transmission wheel and the transmission belt can drive the connecting column 6 on one side of the floating platform 1 to rotate.
