Description
Technical Field
[0001] This utility model belongs to the technical field of temporary holding and transportation of anchovies, and particularly relates to a device for temporary holding and transportation of anchovies. Background Technology
[0002] Coilia ectenes are prone to death during transport due to severe stress or scale loss. Therefore, the temporary holding and transport equipment for Coilia ectenes needs to be specially designed to address their physiological characteristics. The main requirements are: 1. Collision and injury prevention; 2. Aeration and aeration must be provided, avoiding strong air or water currents to prevent head congestion caused by swimming against the current, also known as the "apex phenomenon"; 3. Water temperature should be controlled between 15℃ and 22℃ to avoid overheating stress; 4. A low-light environment is required to avoid strong light stimulation; 5. A slow current of 0.1–0.3 m / s must be maintained to avoid rapid current stress. Based on these requirements, a collision- and injury-preventing cylindrical transport device was specially designed, employing an external aeration and purification water circulation system for water treatment, reducing noise within the tank and maintaining a slow water flow. Summary of the Invention
[0003] To overcome the technical problems described in the background section, this utility model provides a temporary holding and transfer device for codfish, which combines oxygenation and water exchange. Water treatment is performed outside the container to complete purification and oxygenation. The main body of the transfer container is composed of a barrel and an inner cylinder, with a sub-separation space between the barrel and the inner cylinder. This allows water entering the barrel to be buffered by a filter cloth before gently entering the inner cylinder containing the codfish, which helps reduce the stress response of the codfish.
[0004] The technical solution of this utility model is as follows: a temporary holding and transfer device for anchovies, including a cover, a handle, a barrel, and a base. The barrel is provided on the base, the handle is provided on the barrel, and the top is covered by the cover. An inner cylinder concentric with the barrel is embedded from top to bottom inside the barrel. An isolation net is embedded at the bottom of the inner cylinder. There is a gap space between the outer wall of the inner cylinder and the inner wall of the barrel, and several vertically extending combined partition strips are evenly distributed around the axis. The combined partition strips evenly divide the gap space into sub-divided spaces equal to the number of combined partition strips. A water inlet pipe is provided at the top of the barrel, and the water inlet pipe is connected to a sub-divided space. A filter cloth is provided on the inner cylinder corresponding to this sub-divided space. The filter cloth separates the space inside the inner cylinder from the corresponding sub-divided space and allows water to permeate through. A drain pipe is provided at the bottom of the barrel.
[0005] Furthermore, the upper part of the outer wall of the inner cylinder is provided with an upper sealing plate that can press against the upper end of the cylinder body, and the upper sealing plate blocks the upper end of each sub-divided space.
[0006] Furthermore, the combined partition includes an isolation sleeve vertically installed on the inner wall of the barrel and an isolation column vertically installed on the outer wall of the inner cylinder. The isolation column is embedded in the corresponding isolation sleeve to separate the sub-partition spaces on both sides.
[0007] Furthermore, a light-transmitting lens made of sunshade lens is provided in the center of the cover.
[0008] Furthermore, the inlet pipe and outlet pipe are respectively connected to the outlet and inlet of the external aeration and purification water circulation system.
[0009] The beneficial effects of this invention due to the adoption of the above-mentioned technology are as follows: 1. It combines oxygenation and water exchange, using external water treatment to complete purification and oxygenation. The main body of the transfer container is a combination of a barrel and an inner cylinder, with a sub-separation space between the barrel and the inner cylinder. This allows water entering the barrel to be buffered by a filter cloth before gently entering the inner cylinder containing the anchovies, helping to reduce the anchovies' stress response. 2. A light-transmitting lens made of sunshade lens is installed on the cover above the barrel, creating a low-light environment inside the inner cylinder to avoid strong light stimulating the anchovies and causing stress. 3. A combined separator is set between the barrel and the inner cylinder, which not only separates the space for holding cooling ice blocks but also provides a stable guide, helping the inner cylinder to separate smoothly from the barrel and avoiding impact vibration between the inner cylinder and the barrel, which could cause stress to the anchovies.

[0016] Example 1: As Figure 1As shown, this utility model provides a temporary holding and transfer device for Chinese anchovies, including a cover 1, a handle 2, a barrel 3, an inner cylinder 16 and a base 4. The barrel 3 is provided on the base 4, the handle 2 is provided on the barrel 3 and the cover 1 is pressed on the top. A light-transmitting lens 7 made of sunshade lens is provided in the center of the cover 1 to ensure that the Chinese anchovies in the inner cylinder 16 are not exposed to strong light and thus do not suffer stress during the entire transfer process. The inner cylinder 16 is concentric with the barrel 3 and is embedded into the barrel 3 from top to bottom. An isolation net 8 is embedded in the bottom of the inner cylinder 16. The isolation net 8 is set on the connecting cylinder 14. The connecting cylinder 14 is embedded in the bottom of the inner cylinder 16 from bottom to top and is connected to the isolation column 10 on the inner cylinder 16 by a lateral bolt 15 on its side wall. The lateral bolt 15 is countersunk into the isolation column 10.
[0017] The space above the isolation net 8 inside the inner cylinder 16 is a temporary holding space for the anchovies, which is accommodated at a density of 2-3 anchovies / 10 liters of water. There is a gap between the outer wall of the inner cylinder 16 and the inner wall of the barrel 3, and four vertically extending combined partition bars are evenly distributed around the axis. The combined partition bars evenly divide the gap into four sub-divided spaces. The upper part of the outer wall of the inner cylinder 16 is provided with an upper sealing plate 11 that can press against the upper end of the barrel 3. The upper sealing plate 11 seals the upper end of each sub-divided space, and the vertical bolts 17 are threaded into the upper sealing plate 11 and the locking block 13 at the top of the isolation sleeve 12 from top to bottom, so as to achieve a tight connection between the upper sealing plate 11 and the barrel 3.
[0018] The upper part of the barrel 3 is provided with a water inlet pipe 6, which is connected to a sub-divided space and the inner cylinder 16 corresponding to this sub-divided space is provided with a filter cloth 9. The filter cloth 9 separates the space inside the inner cylinder 16 from the corresponding sub-divided space and allows water to permeate through. The bottom of the barrel 3 is provided with a drain pipe 5.
[0019] Ice blocks are placed in the sub-divided space corresponding to the non-inlet pipe 6 in hot weather to cool the inside of the barrel 3. Due to the water flow, the cooling is not very drastic. At this time, it is necessary to nest a heat-insulating shell made of polyethylene foam on the outside of the barrel 3, which is made of ordinary plastic, to prevent external heat from entering the barrel 3 too quickly.
[0020] To ensure that water flow and oxygenation within the tank 3 can be completed silently, preventing stress and death in the anchovies, an external aeration and purification water circulation system is employed. The inlet pipe 6 and outlet pipe 5 on the tank 3 are connected to the outlet and inlet of this external aeration and purification water circulation system, respectively. This system includes a small activated carbon purification filter tank, a PP cotton filter cartridge tank, an ultraviolet disinfection tank, and an aeration tank. Water discharged from the outlet pipe 5 of the tank 3 passes sequentially through the small activated carbon purification filter tank, the PP cotton filter cartridge tank, and the aeration tank. After the cotton filter box, ultraviolet disinfection box, and oxygenation aeration box, the water enters the tank 3 through the inlet pipe 6. For the external oxygenation aeration purification water circulation system, the experimental measure is to use an outdoor power supply, an activated carbon purification filter tank, a booster pump, a 1200g kitchen water purifier of a certain brand, and a small oxygenation aerator to form an experimental external oxygenation aeration purification water circulation system. It is small in size, has good water purification effect, and can meet the water quality requirements during the short-term temporary holding and transfer of anchovies.
[0021] After the transfer is completed, remove the vertical bolts 17 to separate the inner cylinder 16 and the barrel 3. Move the barrel 3 into the anchovy breeding pond as a whole, lift the inner cylinder 16 upward and pull the barrel 3 downward to separate the inner cylinder 16 and the barrel 3 inside the anchovy breeding pond. This avoids separation outside the anchovy breeding pond, which could cause stress to the anchovies. Then, slowly pour the inner cylinder 16 into the anchovy breeding pond to release the anchovies and complete the entire transfer process. This gentle release helps to minimize the stress on the anchovies, especially when the stress level is high in the later stages of the transfer.
