Description

Technical Field

[0001] This utility model relates to the field of fish egg incubation technology, specifically a carp incubation device. Background Technology

[0002] The hatching effect of fish fertilized eggs is affected by a variety of environmental factors. Due to the diversity of natural environments, fish eggs have evolved to be adhesive or non-adhesive, drifting or sinking, etc. For fish fry producers, the hatching of fish eggs is usually carried out under suitable conditions. The appropriate hatching method or incubator is selected based on the nature of the eggs in order to improve the hatching rate and increase economic benefits.

[0003] Carp eggs are adhesive eggs. The initial hatching method was to simulate natural hatching, using palm bark or sieves to collect the fish eggs and then transferring them to a hatching pond for centralized hatching. In recent years, the method of fertilization followed by de-adhesion and high-density aeration hatching has been adopted. The former is less efficient, while the latter is prone to production accidents that can result in complete failure due to factors such as water mold, aeration, and disinfection. Water spray hatching undoubtedly brings a new hatching approach.

[0004] Traditional water-sprinkling incubation methods typically involve setting up a frame indoors and suspending the fish nests evenly on it, or laying the nests flat on a bamboo mat. Water-sprinkling incubation requires maintaining a stable indoor temperature of around 25°C, while ensuring that the water temperature is close to the room temperature. Frequent watering is necessary to keep the fish nests moist, usually every 30 minutes to 1 hour, to ensure that the surface of the fish eggs does not dry out. After about 3 days of water-sprinkling incubation, when the embryos develop eye spots, the fish nests should be promptly transferred to a pond to allow the fry to continue incubating in the natural environment. The biggest advantage of this method is that dead eggs are less likely to breed water mold, reducing the outbreak of water mold disease. However, the disadvantages are that it takes up a lot of space and is also inefficient. Utility Model Content

Detailed Implementation

[0030] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0033] Please see Figures 1-4 This is the first embodiment of the present utility model.

[0034] This embodiment provides a carp incubation device, including:

[0035] Outer frame 1;

[0036] Inner liner 2 is located inside the outer frame 1, and the surface of the inner liner 2 is covered with a layer of silk mesh.

[0037] Limiting ring 6 is located at the top of the inner liner 2;

[0038] Rotating device 9, which is located at the top of the limiting ring 6;

[0039] Spraying device 8 is fixedly installed on the top of rotating device 9;

[0040] Water inlet pipe 5 is located on the right side of the top of the spray device 8.

[0041] For example, the rotating device 9 includes a circular slide groove 91, and an arc-shaped slider 92 is slidably connected to the four sides of the inside of the circular slide groove 91. A rod 93 is provided on the top of the arc-shaped slider 92, and a fixing frame 94 is fixedly connected to the top of the rod 93.

[0042] Furthermore, the outer frame 1 has an overall cylindrical structure, which is corrosion-resistant and has a strong load-bearing capacity. The bottom of the outer frame is welded with four support feet of different heights to ensure that the device is placed stably. The top left side is connected to the external water inlet 4, which is equipped with a PPR material control valve to adjust the water inlet volume and replenish the water inside the outer frame 1 to maintain a stable water level.

[0043] For example, the spray device 8 includes a spray head 81, the top of the spray head 81 is connected to a connecting pipe 82, a pressurizing device 83 is fixedly installed on the top of the connecting pipe 82, and a water inlet hopper 84 is fixedly installed on the top of the pressurizing device 83.

[0044] Furthermore, a drainage device 3 is fixedly installed at the bottom center of the outer frame 1. The drainage device consists of a stainless steel drain pipe and a DN20 ball valve. The ball valve is flexible in opening and closing, making it easy to quickly drain wastewater or accumulated water from the outer frame.

[0045] For example, a circular groove 91 is opened at the top inside the limiting ring 6, an insertion hole 7 is opened at the top of the arc-shaped slider 92, the insertion rod 93 is located inside the insertion hole 7, and several arc-shaped paddles are fixedly connected inside the water inlet 84.

[0046] Furthermore, the inner liner 2 is coaxially arranged with the outer frame 1, and is shaped like an inverted frustum. It is made of food-grade PP material, and the surface is covered with an 80-100 mesh nylon mesh. The mesh is fixed to the outer wall of the inner liner 2 by a high-frequency heat sealing process. The mesh size can accurately support the carp eggs while ensuring smooth water penetration. The bottom outer wall of the inner liner is tightly fitted with the fixing concave ring 10 at the bottom of the outer frame 1, which can limit the lateral swaying of the inner liner 2 and ensure the stability of the inner liner 2 during the incubation process.

[0047] During the initial preparation stage, lay the fish nest with carp eggs attached flat on the sieve mesh of the inner liner 2, with the thickness of the fish nest controlled at 2-3cm; inject warm water into the inner liner 1 through the external water inlet 4 until the water level in the outer frame 1 reaches one-third of its height, and close the external water inlet control valve; check whether the ball valve of the drainage device 3 is closed to ensure that there is no water leakage in the outer frame.

[0048] Incubation and operation phase: The external constant temperature water source and pressurization device 83 are activated; warm water flows into the inlet hopper 84 through the inlet pipe 5.

[0049] Spray device rotation drive: When water flows into the inlet hopper 84, it impacts the internal spiral arc-shaped baffle, generating a rotational torque that drives the inlet hopper 84, pressurizing device 83, connecting pipe 82, and spray head 81 to rotate synchronously. Simultaneously, the fixing frame 94 rotates with the spray head 81, and through the insert rod 93, drives the arc-shaped slider 92 to slide at a uniform speed within the circular groove 91 of the limiting ring 6, achieving stable circular motion of the spray device 8. Uniform spraying and wetting: The pressurizing device 83 pressurizes the warm water in the inlet hopper 84 to 0.2 MPa, and delivers it to the six spray heads 81 through the connecting pipe 82. The spray heads spray atomized water with a particle size of 0.5-1 mm. Because the spray device rotates continuously, the water flow can evenly cover the fish nests inside the inner tank 2, ensuring that the surface of each fish egg remains moist, avoiding the localized drying problem of traditional manual watering.

[0050] In summary, the nested structure of the outer frame 1 and the inner liner 2, which supports multi-layer stacking and improves space utilization, along with the automated spraying and rotating design, eliminates the need for frequent manual watering, allowing for single-person management and reducing labor costs. The screen mesh isolates the fish nest from the bottom wastewater, and the spray water continuously washes the surface of the fish nest, reducing the contact time between dead eggs and the fish nest. At the same time, half of the water inside the outer frame is replaced every 2 hours, effectively reducing the concentration of mold spores in the water and lowering the incidence of water mold disease.

[0051] Please see Figure 5 This is the second embodiment of the present utility model.

[0052] For example, a drainage device 3 is fixedly installed at the bottom of the outer frame 1. The drainage device 3 includes a drain pipe, and a valve is fixedly installed at the bottom of the drain pipe.

[0053] Furthermore, the spray device 8 includes spray heads 81, connecting pipes 82, a pressurizing device 83, and a water inlet hopper 84. There are six spray heads 81, evenly distributed around the inner side of the fixed frame 94. Each spray head is a copper atomizing spray head with a spray angle of 120 degrees and a spray radius of 30 cm, covering the entire top area of ​​the inner liner 2. The connecting pipe 82 is a food-grade PVC pipe, threaded at one end to the spray head 81 and connected to the outlet of the pressurizing device 83 at the other end. The pressurizing device 83 is a miniature centrifugal booster pump, fixedly installed at the bottom of the water inlet hopper 84, which can increase the water pressure to 0.2 MPa, ensuring that the water flow from the spray heads is uniform and has a certain impact force. The water inlet hopper 84 is an inverted conical structure made of PP material, with multiple spirally arranged arc-shaped baffles welded inside. The baffles form a 30-degree angle with the inner wall of the water inlet hopper. When water is injected from the water inlet pipe 5, it can push the baffles to rotate the water inlet hopper. The water inlet pipe 5 is made of PVC. The material is designed so that one end is connected to an external constant temperature water source with a water temperature of 25℃±1℃, and the other end is fixed to the interface on the top right side of the water inlet 84 via a flange.

[0054] For example, a fixing concave ring 10 is fixedly connected to the bottom of the inner liner 2 and the bottom inside the outer frame 1, and an external water inlet 4 is connected to the top of the left side of the outer frame 1.

[0055] Furthermore, the rotating device 9 consists of a circular groove 91, an arc-shaped slider 92, a plug rod 93, and a fixing frame 94. There are four arc-shaped sliders 92, evenly distributed within the circular groove 91, with their curvature matching the groove. A 2mm thick silicone wear-resistant strip is embedded at the bottom. Each arc-shaped slider 92 has a centrally located insertion hole 7 at its top, with anti-slip texture on the inner wall. The plug rod 93 is made of stainless steel, inserted into the insertion hole 7 at its bottom, and welded to the fixing frame 94 at its top. The fixing frame 94 is a ring structure made of aluminum alloy, with its inner side fixedly connected to the outer wall of the spray head 81 of the spray device 8 via bolts, achieving synchronous movement between the rotating device 9 and the spray device 8.

[0056] For example, the inner side of the mounting bracket 94 is fixedly connected to the outer side of the spray head 81, and the pressurizing device 83 increases the pressure when the spray head 81 sprays liquid outward.

[0057] Furthermore, the limiting ring 6 has a ring-shaped structure and is fixed to the top edge of the inner liner 2 by a snap-fit ​​connection. The top of the limiting ring 6 has a circular groove 91 with a smooth inner wall coated with a wear-resistant polytetrafluoroethylene coating to reduce sliding friction resistance and provide a stable motion track for the rotating device.

[0058] During use, water circulation and discharge: the water after spraying flows through the fish nest and the inner tank 2 through the sieve mesh, and permeates to the bottom of the outer frame 1, mixing with the original water in the outer frame; every 2 hours, the ball valve of the drainage device 3 is opened to discharge half of the wastewater, and at the same time the external water inlet 4 is opened to replenish an equal amount of warm water, so as to keep the water in the outer frame clean and prevent wastewater from stagnating and breeding bacteria.

[0059] Later transfer stage: Continue running for about 3 days. When the embryos show eye spots through the sieve mesh of the inner liner 2, turn off the pressurization device 83 and the external water source, and open the drainage device 3 to drain the water in the outer frame 1; remove the limiting ring 6 and the rotating device 9, take the inner liner 2 out of the outer frame 1, and directly transfer the fish nest with the attached eye spot embryos into the pond to complete the hatching process.

[0060] In summary, the rotating atomizing spray head ensures thorough water coverage and uniform moisture distribution for the fish eggs. Furthermore, the constant external water temperature, with temperature fluctuations within the outer frame 1 less than 0.5℃, prevents sudden temperature changes from affecting embryonic development, thus increasing the hatching rate of carp eggs. Operation and maintenance are convenient: the separate design of the inner liner 2 and outer frame 1 facilitates the placement and relocation of fish nests; the screen mesh is removable and replaceable, requiring only rinsing during cleaning; and the modular design of components such as the arc-shaped slider 92 and the insertion rod 93 of the rotating device allows for individual replacement when damaged, eliminating the need for overall repair and reducing maintenance costs.

[0061] All technical features in this embodiment can be freely combined according to actual needs.

[0062] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
