[0016] In some possible embodiments, the conical portion is coaxial with the cylindrical portion, and a water-storage incubation chamber is formed inside along the axial direction.

[0017] In some possible embodiments, the mesh frame is shaped like a frustum with an open top, and the mesh frame includes a mounting bracket disposed along the inner sidewall of the cylindrical portion and a filter mesh covering the outer surface of the mounting bracket.

[0018] In some possible embodiments, the water spray pipe is provided with water outlets at both ends away from the water inlet, and the water outlets are configured to spray water from an external source into the incubator.

[0019] In some possible embodiments, the outlet end is provided with a turbulence screen.

[0020] In some possible embodiments, a water storage tank and a water system are also included, the water system comprising:

[0021] The water inlet pipe has one end connected to the water storage tank, and the other end of the water inlet pipe is respectively provided with a first water inlet pipe connected to the support base and a second water inlet pipe connected to the bottom of the incubator.

[0047] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. It should be understood that the specific embodiments described herein are merely for explaining this application and are not intended to limit this application.

[0048] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0050] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of the incubation device 10 shown in the embodiment of this application. The incubation device 10 includes a base 100, an incubation box 200, a water spray assembly 300, a water storage tank 400, and a water system 500. The incubation box 200 is installed on the base 100, and the water spray assembly 300 is disposed on the top of the incubation box 200. The water system 500 is used for water supply between the water storage tank 400, the incubation box 200, and the water spray assembly 300. By setting up the incubation box 200 and the water spray assembly 300, the water spray assembly 300 is configured to spray externally supplied water onto the water surface inside the incubation box 200 in a rotating manner. In this way, the dissolved oxygen content of the water inside the incubation box 200 is increased evenly. Furthermore, through the structural arrangement of the incubation box 200 and the arrangement of the water system 500, it is convenient to clean and discharge metabolic products and other wastes inside the incubation box 200 before the fish eggs hatch, as well as to replace the water inside the incubation box 200. At the same time, after the fish eggs hatch, the fish fry can be directly discharged from the bottom of the incubation box 200.

[0051] Optionally, an aerator 600 is installed on the bracket of the water shower assembly 300. The aerator 600 is connected to an oxygen supply pipe, and the other end of the oxygen supply pipe extends into the incubator 200 to increase the dissolved oxygen content of the water in the incubator 200. It should be noted that the oxygen supply pipe and the water shower pipe of the water shower assembly 300 do not interfere with each other.

[0052] Optionally, a water inlet structure 700 can be installed on one side of the water storage tank 400. The water inlet structure 700 is used to transport external water sources into the water storage tank 400.

[0053] Please see Figure 2 In some embodiments, the water system 500 may include an inlet pipe 511, an overflow outlet pipe 530, and a drain pipe 540. One end of the inlet pipe 511 is connected to the water storage tank 400, and the other end of the inlet pipe 511 is respectively provided with a first inlet pipe 511 connected to the support base 340 and a second inlet pipe 512 connected to the bottom of the incubator 200. One end of the overflow outlet pipe 530 is connected to the water collection tank 211, and the other end of the overflow outlet pipe 530 can extend to the water storage tank 400. At the same time, a water pump 520 is connected to one end of the inlet pipe 511 inside the water storage tank 400. The water pump 520 is used to provide pressure to output water from the water storage tank 400. The bottom of the incubator 200 is connected to the drain pipe 540.

[0054] It should be noted that valves controlling water flow are installed in the first inlet pipe 511, the second inlet pipe 512, and the drain pipe 540. A valve can also be installed in the overflow drain pipe 530. The specific choice depends on the actual needs. Before the fish eggs hatch, when it is necessary to drain the sewage in the hatching box 200 after cleaning, simply close the valve of the inlet pipe 511 and open the valve of the drain pipe 540. When the hatching box 200 needs to add water, close the valve of the drain pipe 540, and then add water from the bottom of the hatching box 200 through the inlet pipe 511. In this way, the water source in the hatching box 200 can be changed.

[0055] In some embodiments, please refer to Figure 2 and Figure 3 The base 100 supports the incubator 200 to a certain height, so that the bottom of the incubator 200 has a certain height difference with the ground, which facilitates the installation and disassembly of the water pipes. The incubator 200 includes a conical part 210 and a cylindrical part 220. The conical part 210 and the cylindrical part 220 are arranged coaxially and form a water storage incubation chamber along the axial direction. The conical part 210 is fixedly installed or placed on the base 100. The cylindrical part 220 is sealed to the inner wall of the conical part 210. The conical part 210 is in the shape of an inverted cone. A water collection trough 211 is formed around the connection between the cylindrical part 220 and the conical part 210. It should be noted that the diameter of the cylindrical part 220 is smaller than the diameter of the outline circle at the opening of the conical part 210. Thus, the water collection trough 211 is naturally formed at the connection between the cylindrical part 220 and the conical part 210.

[0056] Optionally, the water collection trough 211 is connected to one end of the overflow drain pipe 530. In practical applications, when the incubation box 200 is full of water, it overflows from the top of the cylindrical part 220 and flows into the water collection trough 211. After the water is collected in the water collection trough 211, it is discharged from the overflow drain pipe 530. The water can overflow from the top of the cylindrical part 220 and flow into the water collection trough 211, thereby maintaining the flow of water in the incubation box 200. In this way, the hatching rate of fish eggs is effectively improved.

[0057] Please see Figure 3 and Figure 4 A mesh frame 230 is provided at the top of the cylindrical part 220. The mesh frame 230 is connected to the inner wall of the cylindrical part 220, and the top of the mesh frame 230 is higher than the top of the cylindrical part 220. The mesh frame (230) is shaped like a frustum with an open top. The mesh frame 230 includes a mounting bracket 231 provided along the inner wall of the cylindrical part 220 and a filter mesh 232 covering the mounting bracket 231 to form the outer surface. The mesh size of the filter mesh 232 can be selected according to actual needs. The mesh frame 230 effectively prevents fish eggs or fry from flowing out of the incubation box 200. At the same time, it can buffer part of the impact force of the water sprayed from the water spray component 300, thereby protecting the incubation environment inside the cylindrical part 220.

[0058] In some embodiments, the water spray assembly 300 includes a support frame 310, a drive motor 320, a water spray pipe 330, and a support base 340. The support frame 310 can be rectangular, and one end of the support frame 310 is fixedly connected to the incubator 200. The drive motor 320 is mounted on the surface of the support frame 310. The output shaft of the drive motor 320 can be coaxially arranged with the cylindrical portion 220. The water spray pipe 330 is fixedly connected to the output shaft of the drive motor 320, and a water inlet end 331 is provided on the opposite surface of the connection between the water spray pipe 330 and the output shaft.

[0059] Optionally, the support frame 310 supports the water spray pipe 330 directly above the mesh frame 230, and the drive motor 320 is used to drive the rotation of the water spray pipe 330. Preferably, the water spray pipe 330 has water outlets 332 at both ends away from the water inlet end 331. The water outlets 332 are configured to spray water from the outside into the incubator 200.

[0060] Please see Figure 5 The distance between the water outlet 332 at both ends of the water spray pipe 330 and the connection point between the water spray pipe 330 and the output shaft of the drive motor 320 is equal. This ensures that the water outlet 332 on both sides sprays water evenly during the rotation of the water spray pipe 330. A turbulence screen 3321 can be installed at the water outlet 332 to further buffer the impact force of the water source.

[0061] It is understandable that as the water spray pipe 330 continuously adds water to the incubator 200, the overflow of water from the incubator 200 can cause the egg membranes and their metabolites after the fry hatch to overflow from the top, thereby reducing the accumulation of metabolic products in the incubator 200.

[0062] Please see Figure 6 One end of the support base 340 is rotatably connected to the water inlet end 331, and the other end is fixedly connected to the external water pipe. Specifically, the support base 340 includes a sleeve 341, a sealing ring 342, a bearing 343, and a gasket 344. The outer wall of the sleeve 341 is fixedly connected to the support frame 310 through the support rod 3411. One end of the sleeve 341 is fixedly connected to the first water inlet pipe 511, and the other end is rotatably connected to the water inlet end 331. The sealing ring 342, the bearing 343, and the gasket 344 are coaxially stacked inside the sleeve 341, and the sealing ring 342, the bearing 343, and the gasket 344 are sequentially sleeved on the surface of the water inlet end 331.

[0063] Thus, the sealing ring 342 and the gasket 344 can ensure the sealing of the connection between the first water inlet pipe 511 and the water inlet end 331, and the bearing 343 can further reduce the friction when the water spray pipe 330 rotates.
