[0025] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, if the terms "first", "second", "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] Embodiment 1:

[0028] like Figure 1 , 2 In the illustrated embodiment, the box 101 is used to provide an incubation environment. To ensure the strength of the box 101, the structure of the box 101 includes a support frame. The side of the support frame in contact with the water body is coated with a coating layer with stable chemical properties. The coating layer can be made of stainless steel of types 316, 201, etc., or polyethylene, ABS engineering plastics. The support frame can be welded from profiles, or it can be in the form of a ground structure. To ensure the thermal insulation effect of the water tank, an insulation layer made of aluminum silicate ceramic fiber, aerogel felt or glass wool, polystyrene foam, polyurethane foam, etc. is also provided at the support frame.

[0029] The temperature control component is used to adjust the temperature in the water body. Specifically, the temperature control component includes a temperature control box 107, which is arranged at the bottom or side wall of the box 101. In order to increase the surface area of ​​the temperature control box 107 in contact with the water body and occupy as little space as possible inside the box 101, the temperature control box 107 is arranged in a flat shape, and the temperature control box 107 is filled with a heat transfer medium. The temperature of the heat transfer medium in the temperature control box 107 is adjusted by the air conditioning device 106.

[0030] The oxygenation component is used to pump air into the water body to increase the dissolved oxygen level of the water body. Specifically, the oxygenation component includes an air pump 104 and an air pipe 105. The air pump 104 delivers external air into the box 101 through the air pipe 105. In order to ensure the uniformity of oxygenation, multiple air pipes 105 can be provided, and each air pipe 105 is provided with a plurality of air outlets. Each air outlet is provided with an air head, and the air head can be used to convert air into bubbles of smaller volume to increase the specific surface area in contact with the water body, thereby enhancing the oxygenation effect. Zeolite and bubble stone can be used as the air head as optional forms.

[0031] The temperature sensor set in the box 101 is used to detect the temperature of the water in the box 101. The air conditioning device 106 performs actions according to the feedback of the temperature sensor. In specific use, a certain temperature threshold can be set for the water. The temperature sensor collects the water temperature in real time. When the water temperature is higher than the set threshold, the air conditioning device 106 cools the heat transfer medium to reduce the water temperature; when the water temperature is lower than the threshold, the air conditioning device 106 heats the heat transfer medium to increase the water temperature. The temperature sensor, the air conditioning device 106, and the temperature control component cooperate to create suitable temperature conditions for fish hatching.

[0032] The first rolling curtain 103 disposed on the top of the box 101 can block the light irradiated into the box 101 to adjust the light intensity of the water body. In order to prevent the first rolling curtain 103 from sagging when it is pulled out when the width of the first rolling curtain 103 is wide, a plurality of cross braces 102 are disposed on the body of the first rolling curtain 103.

[0033] Embodiment 2:

[0034] On the basis of Example 1, Figure 3 In the illustrated embodiment, in order to reduce the one-time capture of the fry when transferring the fry and reduce the disturbance to the fry, a fry transfer basket is movably provided in the box 101. Specifically, the fry transfer basket comprises a basket 113, wherein the basket 113 can be welded into a support frame by using profiles such as steel bars and angle steels, a steel plate is provided at the support frame, and a filter screen 112 is provided at the bottom of the basket 113.

[0035] When the fry need to be transferred, the fry basket can be pulled up. During the lifting process of the fry basket, the filter screen 112 blocks the fry to prevent the fry from diving. At the same time, after the fry basket is pulled out of the water, the filter screen 112 supports the fry.

[0036] In order to facilitate the application of force to the seedling transplanting basket when the seedling transplanting basket is pulled up, a hanging ear 111 is provided at the upper edge of the basket body 113 .

[0037] In the present embodiment, a sealing strip or a brush is provided between the inner wall of the basket 113 and the casing 101. The sealing strip or the brush can prevent the fry from diving from the gap between the inner wall of the basket 113 and the casing 101 when the seedling basket is lifted.

[0038] Embodiment 3:

[0039] On the basis of Example 2, Figure 3 In the illustrated embodiment, in order to further facilitate the transfer of fry, a second rolling curtain 114 is provided at the basket 113. When the second rolling curtain 114 is unfolded, the body of the second rolling curtain 114 covers the upper part of the filter 112. In specific use, when the upper edge of the basket 113 is just exposed to the water surface, the second rolling curtain 114 can be unfolded, and the body of the second rolling curtain 114 covers the upper part of the filter 112, so that the filter 112 is in a closed state, and there is still a certain amount of water in the basket 113. At this time, the fry can be poured into the receiving container by tilting the fry transfer basket. During the entire transfer process, the fry does not leave the water, thereby further reducing the damage to the fry.

[0040] In this embodiment, a discharge port is provided at the basket 113, and a baffle 110 is hinged at the discharge port. When the baffle 110 is opened during use, under the guidance of the baffle 110, water mixed with fry flows out from the discharge port to the receiving container.

[0041] In this embodiment, in order to prevent water from flowing out from the gap between the baffle 110 and the discharge port when the baffle 110 is opened, a sealing sheet is provided between the discharge port of the housing 113 and the gap between the baffle 110 , and the sealing sheet is provided in a laminated form.

[0042] In this embodiment, when the weight of the seedling transplanting basket is large, in order to provide a fulcrum for the seedling transplanting basket when it is tilted to pour out the fry, a first clamping seat 108 is provided on the upper part of the box body 101, and a second clamping seat 109 is provided at the basket body 113. When the seedling transplanting basket is lifted to the specified position, the first clamping seat 108 and the second clamping seat 109 are rotatably connected via a bayonet. At this time, the first clamping seat 108 and the second clamping seat 109 cooperate with each other to provide a fulcrum for the seedling transplanting basket, and the seedling transplanting basket can be tilted by lifting the edge away from the first clamping seat 108 and the second clamping seat 109.

[0043] The embodiments described above are only preferred specific implementation methods of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present utility model according to the technical solution and utility model concept of the present utility model, which should be covered by the protection scope of the present utility model.
