[0030] Please refer to Figures 1-7 In fish farming, the hatching of fertilized eggs is a critical step to ensure high yield and high survival rate. Traditional hatching methods usually place fertilized eggs in water and let them hatch naturally. This method relies on the dissolved oxygen in water, so it needs continuous water flow or aeration to maintain the oxygen level, which not only increases the consumption of water resources and electric energy, but also may cause the fish eggs to break due to water flow impact during the hatching process.

[0031] In addition, the traditional flat incubation net is prone to water droplet adhesion due to its small mesh size, which causes newly hatched fry to be trapped in water droplets and fail to shed smoothly. At the same time, such an incubation net is also prone to adsorbing dust in the environment, causing secondary pollution of fish eggs. These problems seriously affect the incubation efficiency and the survival rate of fry. Based on this, the present application provides a fish egg incubation net, which comprises an upper frame 1 for support and a lower frame 5 combined with the upper frame 1 to form a clamping structure;

[0032] A partition plate 4 is arranged between the upper frame 1 and the lower frame 5, and a steel wire group 3 is arranged at the partition plate 4;

[0033] The steel wire group 3 has at least two layers of steel wires, which are arranged in a staggered and uniform interval for fish egg incubation;

[0034] The two layers of steel wires of the steel wire group 3 are arranged on the inner sides of the upper frame 1 and the lower frame 5 respectively, and a fixed interval is maintained between the two layers of steel wires.

[0035] The present embodiment provides a fish egg incubation net, which aims to improve the incubation efficiency of fish eggs and the survival rate of fry. The incubation net is mainly composed of an upper frame 1 and a lower frame 5, which form a stable clamping structure after combination, providing a safe and controllable environment for fish egg incubation.

[0036] Specifically, a partition plate 4 is arranged between the upper frame 1 and the lower frame 5, which not only enhances the stability of the incubation net, but also plays a role in separating and protecting fish eggs. At the partition plate 4, a steel wire group 3 is specially arranged, which is composed of at least two layers of steel wires. These steel wires are arranged in a staggered and uniform interval, which not only ensures sufficient space for fish egg incubation, but also effectively prevents adhesion between fish eggs.

[0037] In order to further optimize the incubation conditions, the two layers of steel wires of the steel wire group 3 are arranged on the inner sides of the upper frame 1 and the lower frame 5 respectively, so that the fish eggs can be uniformly heated, and observation and management are facilitated. At the same time, a fixed interval is maintained between the two layers of steel wires, which is carefully designed. The interval is neither too large to cause fish eggs to scatter, nor too small to limit the incubation space of fish eggs.

[0038] Through the design of the steel wire group 3, adhesion between fish eggs is effectively prevented, ensuring that each fish egg can obtain sufficient incubation space, thereby improving the incubation efficiency. The structural design of the incubation net fully considers the physiological needs of fish egg incubation, provides a suitable incubation environment, helps the healthy incubation of fry, and thus improves the survival rate.

[0039] The clamping structure of the upper frame 1 and the lower frame 5 and the transparency of the steel wire group 3 make it easy to observe and record the state of fish eggs during the incubation process, providing great convenience for breeders.

[0040] Compared with the traditional incubation method, the combination of the partition plate 4 and the steel wire group 3 not only enhances the stability of the incubation net, but also makes the cleaning work simple and easy, effectively preventing the secondary pollution of fish eggs.

[0041] The inner side of the upper frame 1 is provided with one or more grooves near the group of steel wires for accommodating the steel wires and keeping them taut and fixed.

[0042] The inner side of the lower frame 5 is provided with one or more grooves near the other group of steel wires, which are spaced apart from the grooves of the upper frame 1, for accommodating the steel wires and keeping them taut and fixed.

[0043] The upper frame 1, the upper frame 1, and the partition plate 4 are all fixed by fasteners 2 to clamp the steel wire group 3.

[0044] The inner sides of the upper frame 1 and the lower frame 5 of the fish egg incubation net are provided with grooves for accommodating and fixing the steel wire group 3. Specifically, the inner side of the upper frame 1 is provided with one or more grooves near the group of steel wires to accommodate the steel wires and ensure that they can be securely fixed and kept taut. Similarly, the inner side of the lower frame 5 is also provided with grooves near the other group of steel wires, and these grooves are spaced apart from the grooves of the upper frame 1, which can better support the steel wire group 3 and prevent the steel wires from shifting or loosening during use.

[0045] By fixing the upper frame 1, the lower frame 5, and the partition plate 4 together with fasteners 2, a stable clamping structure is formed, effectively clamping the steel wire group 3 and ensuring its stability throughout the incubation process. This design not only ensures the structural integrity of the steel wire group 3, but also helps maintain the overall shape of the incubation net, providing an ideal incubation environment for fish eggs.

[0046] By providing grooves on the inner sides of the upper frame 1 and the lower frame 5, the steel wires can be effectively accommodated and fixed to prevent them from loosening or shifting during use, ensuring the stability and reliability of the incubation net. The grooves of the upper frame 1 and the lower frame 5 are spaced apart, which helps better distribute the tension of the steel wires and improves the uniformity and stability of the steel wire group 3, thus providing more suitable incubation conditions for fish eggs.

[0047] The upper frame 1, the lower frame 5, and the partition plate 4 are fixed by fasteners 2 to form a stable whole, which is convenient for assembly and disassembly, and can adjust the spacing of the steel wire group 3 as needed to adapt to different sizes of fish egg incubation requirements. Since the steel wire group 3 is securely fixed, it reduces the damage to fish eggs or poor incubation caused by loose steel wires, thereby improving the overall incubation success rate.

[0048] Example 2:

[0049] The partition plate 4 comprises a plate body 43, and positioning holes 41 are arranged at the top edges of the plate body 43 at the middle of both sides and at the opposite corners.

[0050] The plate body 43 is integrally formed with a block 44 with a preset angle at the top edges of the plate body 43 at the middle of both sides, which is used to limit the sides of the upper frame 1 and the lower frame 5.

[0051] The plate body 43 is integrally formed with a block 44 with a preset angle at the top edges of the plate body 43 at the middle of both sides, which is used to limit the sides of the upper frame 1 and the lower frame 5.

[0052] In this embodiment, the partition plate 4 of the fish egg hatching net further provides better support and adjustment functions. Specifically:

[0053] The main part of the partition plate 4 is the plate body 43, which is the core support structure of the entire hatching net.

[0054] The plate body 43 is integrally formed with a block 44 with a preset angle at the top edges of the plate body 43 at the middle of both sides, which is used to limit the sides of the upper frame 1 and the lower frame 5.

[0055] The plate body 43 is integrally formed with a block 44 with a preset angle at the top edges of the plate body 43 at the middle of both sides, which is used to limit the sides of the upper frame 1 and the lower frame 5.

[0056] The plate body 43 is integrally formed with a block 44 with a preset angle at the top edges of the plate body 43 at the middle of both sides, which is used to limit the sides of the upper frame 1 and the lower frame 5.

[0057] The plate body 43 is integrally formed with a block 44 with a preset angle at the top edges of the plate body 43 at the middle of both sides, which is used to limit the sides of the upper frame 1 and the lower frame 5.

[0058] The plate body 43 is integrally formed with a block 44 with a preset angle at the top edges of the plate body 43 at the middle of both sides, which is used to limit the sides of the upper frame 1 and the lower frame 5.

[0059] The plate body 43 is integrally formed with a block 44 with a preset angle at the top edges of the plate body 43 at the middle of both sides, which is used to limit the sides of the upper frame 1 and the lower frame 5.

[0060] The plate body 43 is integrally formed with a block 44 with a preset angle at the top edges of the plate body 43 at the middle of both sides, which is used to limit the sides of the upper frame 1 and the lower frame 5.

[0061] The introduction of the jacking part enables the hatching net to flexibly adjust the distance between the upper frame 1 and the lower frame 5, adapt to the hatching requirements of fish eggs of different sizes, and improve the adaptability and flexibility of the hatching net. Therefore, the fastener 2 arranged at this position is a pin shaft matched with the positioning hole 41. When the jacking part is started, for example, an air bag is used to lift the upper frame 1 and the lower frame 5, the distance between the upper frame 1 and the lower frame 5 can be adjusted under the limitation of the pin shaft, so as to adjust the distance between the two groups of steel wire meshes;

[0062] Meanwhile, there is another embodiment, in which the jacking part only lifts the upper frame 1, and the upper frame 1 is adjusted along the pin shaft to adjust the distance.

[0063] The integrated design of the stop block 44 and the mounting hole 42 of the jacking part makes the assembly and disassembly of the whole hatching net more convenient, so as to facilitate daily maintenance and cleaning. The use of the fastener 2 ensures the close connection of each component and reduces possible problems in the assembly and disassembly process.

[0064] By adjusting the jacking part, the distance between the steel wire groups 3 can be accurately controlled, so as to ensure that the fish eggs obtain suitable space and conditions in the hatching process and improve the hatching success rate. The stop block 44 prevents the lateral movement of the upper frame 1 and the lower frame 5, reduces the damage of the fish eggs caused by unstable structure, and further optimizes the hatching environment.

[0065] The above description is only the embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
