Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to an aquatic seedling transfer device. Background Technology

[0002] In the process of cultivating, separating, and selling aquatic seedlings, short-distance transportation is often required. Currently, the most common transportation methods are simple plastic buckets, bags, or water tanks. These traditional methods have the following problems: 1) Dissolved oxygen problem: When the loading density is high, the dissolved oxygen in the water drops rapidly. Relying solely on natural diffusion or artificial water exchange cannot meet the respiratory needs of the seedlings, which can easily cause hypoxia stress or even death of the seedlings, affecting the survival rate. 2) Low space utilization: Traditional round or irregularly shaped containers are unstable when stacked, cannot be effectively stacked vertically, occupy a lot of space, and are particularly inconvenient for transport vehicles or temporary storage points, resulting in low transfer efficiency.

[0003] To address the aforementioned issues, some technical solutions have introduced independent oxygenation pumps, but these require an external power source and are limited in use in the field or in environments without electricity. Other solutions have designed stacked structures, but often overlook the impact of the stacked state on internal circulation and oxygenation, leading to a deterioration of the environment in the lower container. Therefore, we propose an aquatic seedling transfer device. Utility Model Content

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-4 A seedling transfer device for aquatic organisms is provided. This device includes a box 1, with a seedling inlet at the top of the box 1 and a drain outlet 3 with a valve 4 (such as a ball valve) at the bottom of the side wall of the box 1. An aeration mechanism is installed inside the box 1, which includes a vertically arranged drive rod 601, a horizontally arranged water-dispensing plate 603 (made of ABS plastic), and a pressing protrusion 602 (made of stainless steel, 10mm in diameter) located on the sealing cover 2. The pressing protrusion 602 penetrates through... The top of the sealing cover 2 is fixedly connected to the drive rod 601 at its lower end. The end of the drive rod 601 away from the pressing protrusion 602 is connected to the water-dispensing plate 603. The pressing protrusion 602 is connected to the inner top wall of the sealing cover 2 through the return spring 604 (304 stainless steel, wire diameter 1.2mm). In application, the pressing protrusion 602 drives the water-dispensing plate 603 to move up and down, which can realize water disturbance and oxygenation without electricity, solving the problem of oxygen deficiency during high-density transportation. It is especially suitable for outdoor or power-free environments. The bottom of the container 1 is equipped with a stacking positioning protrusion 7, and the top of the sealing cover 2 is provided with a stacking positioning groove 8 that matches the shape of the stacking positioning protrusion 7. In application, the matching design of the bottom stacking positioning protrusion 7 and the top stacking positioning groove 8 enables multiple containers 1 to be stacked stably and vertically, greatly improving the space utilization rate of transportation and storage, and avoiding the defects of unstable stacking of traditional containers.

[0022] Reference Figure 1 and Figure 2The tank 1 has an inclined guide plate 101 near the bottom. If it is tilted at 10°, the lowest point of the inclined guide plate 101 points to the drain outlet 3. In application, when the inclined guide plate 101 drains water, it guides the water flow and residue to the drain outlet 3, reduces the dead water area at the bottom of the tank, prevents pollutants from accumulating and affecting water quality, and facilitates thorough emptying and cleaning.

[0023] Reference Figures 1-3 At least one side wall of the box body 1 is provided with a ventilation grid window 102. The inner side of the ventilation grid window 102 is covered with a removable escape-proof net 9. For example, the two side walls of the box body 1 are provided with honeycomb ventilation grid windows 102 (total area ≥ 200cm²), and the inner side is installed with a snap-fit ​​40-mesh nylon escape-proof net 9. In application, the ventilation grid window 102 ensures air circulation and assists in oxygenation. At the same time, the removable escape-proof net 9 prevents the seedlings from escaping, taking into account both ventilation and safety, and is easy to clean and maintain.

[0024] Reference Figure 1 and Figure 2 Handles 103 for applying force are fixedly installed on the two opposite side walls of the box 1. In application, the symmetrical handles 103 design facilitates manual handling and loading / unloading, reduces operational intensity, and improves transfer efficiency.

[0025] Reference Figure 2 and Figure 3 A limiting piece 6021 is fixedly installed at the bottom of the pressing protrusion 602. The two ends of the return spring 604 are fixedly installed on the inner top wall of the limiting piece 6021 and the sealing cover 2, respectively. In application, the two ends of the return spring 604 are fixed to ensure that the drive rod 601 is stably reset after pressing, to avoid the spring return spring 604 from shifting or getting stuck, and to enhance the reliability of the oxygenation mechanism.

[0026] Reference Figures 2-4 A sealing bearing 5 is provided at the point where the pressing protrusion 602 and the sealing cover 2 pass through. In application, the design of the sealing bearing 5 prevents water leakage from the gap between the pressing protrusion 602 and the sealing cover 2, while reducing frictional resistance and making the pressing operation smoother.

[0027] Reference Figure 2 and Figure 4 The water deflector 603 has multiple through holes 6031 evenly spaced (2cm apart, accounting for 30% of the total area). The water deflector 603 is located in the upper middle part of the water body inside the tank 1. In application, the through holes 6031 reduce water deflection resistance and expand the water disturbance range. At the same time, being located in the upper middle part of the water body can efficiently drive the surface water to contact with the air, thereby improving dissolved oxygen efficiency.

[0028] Reference Figure 1 and Figure 2The palletizing positioning boss 7 is a truncated cone, and the palletizing positioning groove 8 is a corresponding conical groove. In application, the cooperation between the conical palletizing positioning boss 7 and the palletizing positioning groove 8 provides a self-centering effect, enhances stacking stability and anti-displacement ability, and is suitable for bumpy transportation environments.

[0029] The working principle of this utility model is as follows: Seedling preparation stage: First, confirm that the escape prevention net 9 is undamaged and the valve 4 is sealed. Then, inject 1 / 2 volume of clean breeding water (water depth about 15cm) into the box 1. Finally, put in the seedlings (density ≤ 500 fish / box) through the seedling inlet and replenish the water level to 2 / 3 height (about 20cm). Transshipment operation phase: Artificial oxygenation: First, press the protruding column 602 once every 15 minutes (press down 5cm), and drive the water-dispensing plate 603 to move up and down to stir the water. Press 3-5 times each time. During this period, when the water-dispensing plate 603 rises, the through hole 6031 forms an upward water flow, and when it falls, it generates a vortex, which promotes gas-liquid exchange and does not require electricity. Palletizing and transporting: After closing the sealing cap 2 of a single box, align the bottom palletizing positioning protrusion 7 with the lower box cover palletizing positioning groove 8 and stack vertically (≤3 layers). It can be moved by forklift or manually through the handle 103. The stacked body can be directly loaded into the transport vehicle, which can save half of the plane space. Seedling unloading and cleaning stage: First, open valve 4 and tilt the guide plate 101 to quickly drain the sewage / residue from the drain outlet 3. Then, open the sealing cover 2 and tilt the box 1 to let the seedlings slide out from the seedling inlet with the water flow (or scoop them out with a water ladle). Finally, remove the anti-escape net 9 and rinse it. Soak the box 1 in disinfectant and then let it dry for later use.
