Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a fish egg incubator. Background Art

[0002] Currently, in fish farming, the hatching and cultivation of fish fry are separated. The general practice is to first place the fertilized eggs in a hatching pond and incubate them with running water. The fry hatched from the fertilized eggs are then transferred to an outdoor pond to be cultivated into standard fry, or directly cultivated into commercial fish. However, existing fish egg incubation devices have some shortcomings. During the process of fish egg incubation, many conditions need to be met, such as a stable incubation environment. Existing devices can provide the required oxygen for the fish eggs, but the rate of live water inflow is easily limited. If the rate of live water inflow is too large, it is easy to cause impact on the fish eggs, causing them to rupture, and it is impossible to provide a stable environment for the fish egg hatching, affecting the hatching rate. If it is too small, it cannot provide sufficient oxygen, which also affects the hatching rate and the quality of the hatched fry. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems in the prior art. To this end, one purpose of the present invention is to provide a fish egg incubator that can adjust the water inlet rate as needed, provide a stable environment for fish egg incubation, and improve the hatchability.

[0004] In order to solve the above technical problems, the technical solution provided by the present invention is: a fish egg incubator, comprising:

[0005] water pumps;

[0006] A water circulation pipeline, which is connected to the output end of the water pump and includes a water supply pipeline, an exhaust pipeline and a return pipeline connected to the water supply pipeline. The return pipeline is provided with a return water regulating valve to control the water flow size of the hemispherical incubation container;

[0007] The incubation mechanism comprises a bracket and a hemispherical incubation container arranged on the bracket, the output end of the water supply pipeline is arranged in the center of the hemispherical incubation container, and a drainage pipe is provided on the side wall of the hemispherical incubation container.

[0008] Preferably, the water supply pipeline includes a first connecting pipe connected to the output end of the water pump, the other end of the first connecting pipe is connected to a first tee, the first tee is connected to a second connecting pipe, the other end of the second connecting pipe is connected to a second tee, the second tee is connected to a third connecting pipe, and the end of the third connecting pipe is arranged in the hemispherical incubation container.

[0009] Preferably, the first tee is also connected to the return pipe, and the return pipe is located below the third connecting pipe.

[0010] Preferably, the second three-way connection is also connected to the exhaust pipeline, and the exhaust pipeline is located above the third connecting pipe.

[0011] After adopting the above structure, the utility model has the following advantages:

[0012] The present application achieves continuous flow of water through a water circulation pipeline driven by a water pump, which helps to maintain clean water quality, constant water temperature and sufficient dissolved oxygen in the hemispherical incubation container, providing good environmental conditions for the hatching of fish eggs. The setting of the exhaust pipeline can help maintain uniform water flow into the incubation container, preventing the water flow from being large or small due to uneven gas, which may scatter the fish eggs and flow out of the incubator. The return water regulating valve set on the return water pipeline allows the user to adjust the water flow rate according to actual needs, thereby optimizing the incubation environment and providing a stable environment for the hatching of fish eggs. The drain pipe set on the side wall of the hemispherical incubation container can conveniently discharge excess water, realizing water circulation in the incubation system.

[0020] Combined with attachment Figure 1-Figure 2 A fish egg incubator includes a water pump 1, a water circulation pipeline connected to the water pump 1, and an incubation mechanism coordinated with the water circulation pipeline. The water pump 1 pumps constant temperature water into the water circulation pipeline and flows into the incubation mechanism. The water is circulated through the water circulation pipeline and the incubation mechanism.

[0021] The water circulation pipeline is connected to the output end of the water pump 1, including a water supply pipeline, an exhaust pipeline 8 connected to the water supply pipeline, and a return pipeline 7. The return pipeline 7 is provided with a return water regulating valve 4. The return water regulating valve 4 adopts a switch valve to control the water flow by adjusting the size of the cross section.

[0022] The water supply pipeline includes a first connecting pipe 6 connected to the output end of the water pump 1, the other end of the first connecting pipe 6 is connected to the first tee 3, the first tee 3 is connected to the second connecting pipe 2, the other end of the second connecting pipe 2 is connected to the second tee 5, the second tee 5 is connected to the third connecting pipe 9, the end of the third connecting pipe 9 is set in the hemispherical incubation container 10, the first tee 3 is also connected to the return pipe 7, and the return pipe 7 is located below the third connecting pipe 9, the second tee 5 is also connected to the exhaust pipe 8, and the exhaust pipe 8 is located above the third connecting pipe 9.

[0023] The incubation mechanism includes a bracket 12 and a hemispherical incubation container 10 arranged on the bracket 12. The output end of the water supply pipeline is arranged in the hemispherical incubation container 10. A drain pipe 11 is provided on the side wall of the hemispherical incubation container 10 for draining water in the hemispherical incubation container 10 that exceeds the bottom of the cross-section of the drain pipe 11.

[0024] When the device of the present application is in use, the water pump 1 is used to extract the constant temperature water in the container and pump it into the water circulation pipeline. The water first passes through the first tee 3 and enters the return pipe 7. The remaining water flows into the hemispherical incubation container 10 through the second connecting pipe 2, the second tee 5 and the third connecting pipe 9. The larger the opening of the return water regulating valve 4, the greater the flow through the return water pipe 7, and the smaller the amount of water entering the hemispherical incubation container 10.
