Description

Technical Field

[0001] The utility model belongs to the technical field of hatching devices, and more specifically, relates to a fish egg hatching device. Background Art

[0002] In the existing aquaculture technology, the hatching of fish eggs is a crucial link, which is directly related to the survival rate, growth rate and final yield of fry. However, traditional fish egg hatching devices often face problems such as high equipment cost, complex structure, inconvenient operation, and inapplicability to small-batch fish egg hatching.

[0003] Specifically, traditional fish egg hatching devices usually include multiple functional modules, such as a water quality circulation system, a temperature control system, an oxygen supply system, and an egg grain separation and cleaning device, etc. These modules often require complex pipeline connections and electrical controls, making the structure of the entire device extremely large and cumbersome. The complex structure also brings difficulties in maintenance. Since the components are closely connected, once a certain link fails, it is often necessary to disassemble the entire device or most of the components for repair, which is not only time-consuming and laborious, but may also have an adverse impact on the fish eggs being hatched. At the same time, the complex structure also means higher manufacturing costs, which is a high cost for hatching small-batch fish eggs. Summary of the Utility Model

[0004] The purpose of the embodiment of this application is to provide a fish egg hatching device to solve the technical problems of complex structure and high manufacturing cost of the fish egg hatching device in the prior art.

[0005] To achieve the above purpose, the technical solution adopted in this application is:

[0006] Provide a fish egg hatching device, including:

[0007] An incubation box;

[0008] An incubation net assembly placed in the incubation box, the incubation net assembly includes a net pocket and a floating ring, the net pocket has an opening, and the floating ring is connected to the opening;

[0009] An inflation assembly, including an air stone, an air pipe and an air pump, one end of the air pipe is connected to the air stone, the other end of the air pipe is connected to the air pump, and the air stone is placed at the bottom of the net pocket.

[0010] As a further improvement of the above technical solution:

[0011] Optionally, the incubation box further includes a drainage structure, the drainage structure includes a drainage port at the bottom of the incubation box, a drainage valve installed at the drainage port, and the drainage valve is used to control the opening and closing of the drainage port.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] The present application provides a fish egg hatching device, which includes a hatching box, a hatching net assembly and an air inflation assembly. The hatching box is used for containing hatching liquids such as water, nutrient solution, and sterilizing solution to provide a necessary living environment for fish eggs. The hatching net assembly is placed in the hatching box. The hatching net assembly includes a net pocket and a floating ring. The mesh size of the net pocket should not only effectively prevent fish eggs and fry from escaping, but also allow nutrients in the hatching liquid to freely flow through, promoting uniform oxygenation of fish eggs. The open mouth of the net pocket is convenient for operators to fish out the hatched fry at an appropriate time. The floating ring is connected to the open mouth, and using the buoyancy of the floating ring, the open mouth of the net pocket is always kept on the water surface to prevent the net pocket from falling to the bottom of the hatching box. The air inflation assembly includes an air stone, a gas pipeline and an air pump. One end of the gas pipeline is connected to the air stone, and the other end of the gas pipeline is connected to the air pump. After the air pump is started, air is delivered to the air stone through the gas pipeline. These airs are refined inside the air stone and then released into the hatching liquid in the form of dense and uniform small bubbles, increasing the dissolved oxygen content in the hatching liquid and providing a sufficient oxygen environment for fish eggs and fry. The air stone is placed at the bottom of the net pocket, and the bubbles released by it can drive the hatching liquid to form a water flow, promoting the swimming of fish eggs in the hatching liquid, preventing adhesion between fish eggs, and further improving the hatching success rate.

[0034] As Figure 1 shown, the present application provides a fish egg hatching device, which includes an incubation box 1, an incubation net assembly 2 and an aeration assembly 3. Among them, the incubation box 1 is made of a material that is corrosion-resistant, easy to clean, and has a low manufacturing cost, such as plastic. The incubation box 1 is used to hold hatching liquids such as water, nutrient solution, and sterilizing solution, providing a necessary living environment for fish eggs. The incubation net assembly 2 is placed in the incubation box 1. The incubation net assembly 2 includes a net pocket 21 and a floating ring 22. The mesh size of the net pocket 21 should not only effectively prevent fish eggs and fry from escaping, but also allow nutrients in the hatching liquid to flow freely, promoting the uniform oxygenation of fish eggs. The open mouth of the net pocket 21 facilitates the operator to fish out the hatched fry at an appropriate time. The floating ring 22 is connected to the open mouth, and using the buoyancy of the floating ring 22, the open mouth of the net pocket 21 is always kept on the water surface, preventing the net pocket 21 from falling to the bottom of the incubation box 1. The aeration assembly 3 includes an air stone 31, an air delivery pipe 32, and an air pump 33. One end of the air delivery pipe 32 is connected to the air stone 31, and the other end of the air delivery pipe 32 is connected to the air pump 33. After the air pump 33 is started, air is delivered to the air stone 31 through the air delivery pipe 32. These airs are refined inside the air stone and released into the hatching liquid in the form of dense and uniform small bubbles, increasing the dissolved oxygen content in the hatching liquid and providing a sufficient oxygen environment for fish eggs and fry. Particularly importantly, the air stone 31 is placed at the bottom of the net pocket 21, and the bubbles released by it can drive the hatching liquid to form a water flow, promoting the movement of fish eggs in the hatching liquid, preventing the adhesion between fish eggs, and further improving the hatching success rate.

[0035] As Figure 1 shown, in an embodiment of the present application, the incubation box 1 further includes a drainage structure 4, and the drainage structure 4 is used to drain the sediment in the incubation box 1 and the hatching liquid that needs to be replaced. The drainage structure 4 includes a drainage port 41 located at the bottom of the incubation box 1 and a drainage valve 42 installed at the drainage port 41. The drainage valve 42 is used to control the opening and closing of the drainage port 41. When the drainage valve 42 is opened, the hatching liquid in the incubation box 1 can be discharged from the drainage port 41 at the bottom. Under the protection of the net pocket 21, fish eggs and fry will not be discharged. When the drainage valve 42 is closed, the incubation box 1 can start storing liquid again.

[0036] As Figure 1As shown, in an embodiment of the present application, the number of drain outlets 41 is multiple, and a drain valve 42 is installed corresponding to each drain outlet 41. Through the coordinated operation of the multiple drain outlets 41 and the drain valves 42, the drainage structure 4 in this embodiment can significantly improve the drainage efficiency, shorten the drainage time, and reduce the potential impact on the hatching environment caused by long-term drainage. At the same time, the design of multiple drain outlets 41 also allows users to selectively open some drain outlets for local drainage according to actual needs, or open all drain outlets simultaneously to achieve rapid and comprehensive drainage operations, thereby improving the flexibility and convenience of operation.

[0037] As Figure 1 shown, in an embodiment of the present application, the gas delivery pipe 32 directly extends from the drain outlet 41 into the inner side of the hatching box 1, thereby shortening the length of the gas delivery pipe 32 at one end of the air stone 31, effectively avoiding the long and tortuous pipe routing that may exist in the traditional layout, and reducing the resistance and loss of gas during transportation.

[0038] As Figure 1 shown, in an embodiment of the present application, the hatching box 1 includes a cylindrical portion 11 and a conical bottom 12, and the cylindrical portion 11 and the conical bottom 12 are integrally formed to ensure their seamless connection. The cylindrical portion 11 is located above the conical bottom 12, and the drain outlet 41 is provided at the tip of the conical bottom 12. With the use of this conical structure, during the hatching process, as the liquid naturally settles and separates, precipitates such as impurities and undissolved substances will gradually converge towards the conical bottom 12 and settle to its tip region due to gravity. At this time, the position of the drain outlet 41 is exactly in the concentrated area of the precipitates, enabling the liquid containing a large amount of precipitates to be easily and efficiently discharged when it is necessary to drain excess liquid or perform cleaning and maintenance, without worrying about the precipitates clogging the drainage process or having an impact.

[0039] As Figure 1 shown, in an embodiment of the present application, the fish egg hatching device of the present application further includes a support frame 5, and the hatching box 1 is placed on the support frame 5. The support frame 5 is used to support and fix the hatching box 1. The support frame 5 is specifically made of stainless steel, and the stainless steel material has good corrosion resistance, high strength, and good mechanical properties, which can effectively resist the erosion of environmental factors on the support frame 5.

[0040] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
