DETAILED DESCRIPTION

[0035] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0036] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0037] like Figure 1-Figure 7 As shown, an embodiment of the present invention provides a static water-pushing fish egg hatching device, including a hatching tank 100, a hatching cage 200 and a driving mechanism 300.

[0038] The hatching tank 100 is filled with water. The hatching tank 100 of this embodiment is preferably a strip-shaped tank.

[0039] It is understandable that in other embodiments, the hatching tank 100 may also be a circular tank, a square tank or a tank structure of other shapes.

[0040] The hatching cage 200 is placed in the water in the hatching tank 100, and the inside of the cage is used to accommodate fish eggs.

[0041] In some embodiments, reference Figure 1-Figure 5 , longitudinal guide rails 110 are arranged on the inner sides of the groove walls on both sides of the hatching groove 100.

[0042] The hatching cage 200 includes a support frame 210 and a plurality of cage units 220 mounted on the support frame 210 . Both sides of the support frame 210 are movably mounted on the longitudinal guide rails 110 on the corresponding sides.

[0043] The support frame 210 of the hatching cage 200 is installed on the longitudinal guide rail 110, and the support frame 210 can move along the longitudinal guide rail 110. The cage monomer 220 is installed on the support frame 210. The movement of the support frame 210 can drive the cage monomer 220 to move. This not only meets the movement requirements of the hatching cage 200, but also can form a stable support for the hatching cage 200, ensuring the smooth movement of the hatching cage 200.

[0044] It should be noted that the fish eggs of this embodiment are spread flat in each net cage monomer 220 with an appropriate thickness to ensure that the fish eggs are not squeezed.

[0045] Optionally, a supporting flange 221 is provided at the upper end of the cage unit 220 , and the cage unit 220 passes through the supporting frame 210 , and the supporting flange 221 at the upper end thereof is supported on the supporting frame 210 .

[0046] It can be understood that the water level in the hatching tank 100 is lower than the support frame 210. When the cage unit 220 is supported on the support frame 210 by the support flange 221, its lower part can be immersed in the water in the hatching tank 100, so that the cage unit 220 has a water environment for hatching fish eggs. At the same time, such a design also makes it easy to remove the cage unit 220 from the support frame 210.

[0047] The number of the cage units 220 shown in this embodiment is specifically four, which are arranged in sequence along the longitudinal direction.

[0048] It is understandable that in other embodiments, the number of the mesh cage units 220 may be one, two, three or other numbers, and the number of the mesh cage units 220 is not specifically limited.

[0049] Optionally, in order to reduce the friction resistance of the hatching cage 200 moving along the longitudinal guide rail 110, at least two track wheels 211 are provided at the bottom of both sides of the support frame 210, and the track wheels 211 on both sides of the support frame 210 are respectively installed on the longitudinal guide rail 110 on the corresponding side, so that driving the hatching cage 200 to move is more labor-saving.

[0050] The driving mechanism 300 is used to drive the hatching cage 200 to move back and forth in the hatching tank 100 .

[0051] In some embodiments, reference Figure 6 The driving mechanism 300 includes a driving mounting base 310 , a driving motor 320 , a crank 330 , a slider 340 and a connecting rod 350 .

[0052] The driving mounting base 310 is fixedly arranged at one end of the hatching trough 100, the driving motor 320 is fixed to the driving mounting base 310, the crank 330 is vertically fixedly connected to the output end of the driving motor 320, the slider 340 is longitudinally slidably installed on the mounting base, the slider 340 is provided with a push rod 341 which penetrates into the hatching trough 100 and is connected to the hatching cage 200, and the two ends of the connecting rod 350 are respectively hinged to the crank 330 and the slider 340.

[0053] Optionally, the drive installation base 310 is a box structure, and the drive motor 320 , the crank 330 , the slider 340 and the connecting rod 350 are all arranged in the drive installation base 310 .

[0054] Optionally, the push rod 341 of this embodiment is specifically connected to the support frame 210 of the hatching cage 200 .

[0055] In this embodiment, the motor can drive the crank 330 to rotate, the crank 330 drives the slider 340 to slide back and forth through the connecting rod 350, and the slider 340 drives the hatching cage 200 to move back and forth through the push rod 341.

[0056] It is understandable that in other embodiments, the driving mechanism 300 may adopt a driving structure such as a telescopic push rod or a motor screw.

[0057] During the process of hatching fish eggs of the present invention, the fish eggs are placed in the hatching net cage 200, and the hatching net cage 200 is placed in the water body in the hatching tank 100. At the same time, the hatching net cage 200 is driven to move back and forth in the water body, playing the role of static water pushing to simulate water flow. The fish eggs are like being in the arms of the mother, which has little damage to the fish eggs and has a good oxygenation effect, thereby achieving a suitable environment, thereby improving the hatching rate of the fish eggs.

[0058] In some embodiments, reference Figure 1 , Figure 2 and Figure 7 The fish egg hatching device further includes a circulating water circuit 400 , and the circulating water circuit 400 includes a filter tank 410 and a circulating pump 420 .

[0059] The filter tank 410 is disposed below the hatching tank 100 , and a water outlet pipe 120 connected to the filter tank 410 is disposed at the bottom of the hatching tank 100 .

[0060] The circulation pump 420 is used to transport the water filtered by the filter tank 410 to the hatching tank 100 .

[0061] During the hatching process of fish eggs, the water in the hatching tank 100 can flow into the filter tank 410 below it through the outlet pipe 120, and after being filtered by the filter tank 410, it is transported back to the hatching tank 100 through the circulation pump 420, thereby realizing the circulation filtration of the water body and ensuring stable water quality.

[0062] Optionally, the circulating water circuit 400 also includes a spray pipeline, which includes a spray main pipe 430 and a plurality of spray branch pipes 440 connected to the spray main pipe 430. The spray main pipe 430 is connected to the output end of the circulating pump 420 through a pipeline. Each spray branch pipe 440 extends to the top of the hatching cage 200, and a nozzle 441 is provided at the water outlet end of each spray branch pipe 440.

[0063] The circulated treated water is sprayed onto the water surface of the hatching tank 100 through the nozzle 441, which can further increase the oxygen content in the water.

[0064] It is understandable that the present embodiment does not impose any specific limitation on the number of the spray branch pipes 440 , but it is preferred that the number of the spray branch pipes 440 corresponds one-to-one to each mesh box unit 220 .

[0065] Optionally, the circulating water circuit 400 further includes a temperature control box 450 and an ultraviolet sterilization tube 460 .

[0066] The input end of the temperature control box 450 is connected to the output end pipeline of the circulation pump 420 , the output end of the temperature control box 450 is connected to the output end pipeline of the ultraviolet sterilization tube 460 , and the output end of the ultraviolet sterilization tube 460 is connected to the spray main pipe 430 pipeline.

[0067] It is understandable that the temperature control box 450 can heat or cool the circulating water to control the water in the incubation tank 100 at a suitable temperature. The temperature control box 450 can heat directly using electric heating elements, and the temperature control box 450 can cool using compressor cooling or semiconductor cooling.

[0068] It is understandable that the ultraviolet sterilization tube 460 includes an outer tube and an ultraviolet lamp disposed inside the outer tube. When water flows between the outer tube and the ultraviolet lamp, it can be sterilized by the ultraviolet rays emitted by the ultraviolet lamp, thereby sterilizing the circulating water.

[0069] This embodiment filters, sterilizes and controls the temperature of the circulating water, thereby ensuring that the water in the hatching tank 100 maintains stable water quality for a long time.

[0070] In some embodiments, reference Figure 1 and Figure 2 The fish egg hatching device also includes a frame 500, a hatching tank 100 and a driving mechanism 300 are installed on the upper part of the frame 500, a filter tank 410, a circulation pump 420 and a temperature control box 450 are installed on the lower part of the frame 500, and a spray pipeline and an ultraviolet sterilization tube 460 are installed on the side of the frame 500.

[0071] All mechanisms of the fish egg hatching device are integrated on the frame 500, so the integrity is better.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
