Description

Technical Field

[0001] This application relates to the field of fish egg incubation technology, and more specifically, to a portable fish egg incubation device. Background Technology

[0002] Artificial breeding is an essential step in achieving large-scale fish farming, and fish egg hatching is a crucial link in this process. Fish egg hatching devices provide a suitable hatching environment for fish eggs under artificially controlled conditions to improve hatching success rates and fry quality. Based on their physical characteristics, fish eggs can be classified into buoyant eggs, sinking eggs, semi-buoyant eggs (drifting), and adhesive eggs. Their hatching devices are also diverse, ranging from traditional equipment such as hatching tanks, hatching rings, and hatching bags, to patented products such as CN113519418B, CN106508756A, CN119404782A, CN118104588A, and CN106719167A.

[0003] However, existing fish egg incubation devices are either complex in structure, difficult to move, lack water exchange, or have poor versatility. Therefore, there is an urgent need for a utility model of a fish egg incubation device that is portable, easy to operate, and highly versatile. Utility Model Content

[0041] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0042] Example 1

[0043] Reference Figure 1-7 The present application provides a portable fish egg hatching device, which includes a hatching component and an oxygenation component; the oxygenation component is located at the upper port of the hatching component and is used to oxygenate the water inside the hatching component.

[0044] The hatching assembly includes a hatching net box 1, the main body of which is made of circular plastic with a mesh size of 2-3 cm. When unfolded, it can support the space inside the net for releasing fish eggs. A support ring 3 is provided at the opening of the hatching net box 1, and multiple annular hooks 4 are provided on the support ring 3. In this embodiment, there are 2-4 annular hooks 4, evenly distributed on the support ring 3. A float 2 is provided on the upper outer side of the hatching net box 1. The float 2 is made of rigid foam or a sealed hollow body, and its buoyancy can support the entire hatching device, including the aeration components. When the hatching device is in use, the part above the float 2 is exposed above the water surface, while the part of the net box below the float 2 is below the water surface. The float 2 is an annular float 2 or a float ball. A 60-100 mesh silk gauze lining 7 is attached to the inside of the hatching net box 1 to allow water to pass through while separating eggs or fry.

[0045] The oxygenation assembly includes a cross bracket 6, a central control component 5, a telescopic rod 8, and a water agitator blades 9. The cross bracket 6 is snapped into the support ring 3. The central control component 5 is installed on the upper end of the cross bracket 6. The upper end of the telescopic rod 8 is connected to the central control component 5, and its lower end extends into the incubation net box 1. The water agitator blades 9 are installed on the lower part of the telescopic rod 8.

[0046] like Figure 7 The telescopic rod 8 is composed of multiple sections of tubing that are nested together. The upper and lower parts of the inner wall of the tubing are provided with multiple slots, and the upper and lower parts of the outer wall are provided with multiple elastic protrusions. When in use, the protrusions and slots of adjacent tubing engage with each other, limiting the tubing and thus enabling the telescopic rod 8 to extend and retract, while also preventing the tubing from rotating axially.

[0047] This portable fish egg hatching device utilizes lightweight materials and a retractable, foldable, and detachable design, making it easy to assemble, disassemble, and carry. It is simple to operate, requires no external power supply, and is suitable for various hatching scenarios such as workshop cement ponds and seedling ponds. It solves the problems of existing hatching devices being immobile, structurally complex, and requiring complicated assembly and operation. The retractable impeller design allows for stirring fish eggs at different water layers as needed, suitable for floating, sinking, semi-floating, and de-adhesive sticky eggs, offering strong versatility. It overcomes the limitations of existing hatching devices that have specific requirements for fish eggs. The water-permeable, egg-separating net cage and lining allow for natural water exchange with the outside environment when used in large bodies of water, ensuring the quality of the hatching water. It eliminates the need for manual or mechanical water changes required in existing technologies. The impeller connected to motor 51 agitates the water to increase oxygen, simulating a natural water flow environment with significant oxygenation effects. It also addresses the risks of damage to newly hatched fry caused by air bubbles from airstones, uneven airstone distribution leading to oxygen deprivation and death of fish eggs, mold growth, and water spoilage, all of which reduce hatching rates in existing technologies.
