Description

Technical Field

[0001] This utility model relates to the field of aquaculture auxiliary equipment technology, and in particular to a zoned isolation transfer box for diseased fish. Background Technology

[0002] In the fields of aquaculture, aquarium pet veterinary medicine, and aquatic biological research, the safe transport of diseased fish (or suspected diseased aquatic organisms) is a crucial link in preventing the spread of pathogens and ensuring the health of farmed populations. Traditional transport methods mostly rely on ordinary plastic boxes, foam boxes, or simple metal containers, which have the following significant drawbacks: First, the risk of cross-infection is high. Existing transport vehicles are mostly single-chamber structures. When diseased fish from different sources and with different symptoms are mixed together, pathogens in the water (such as bacteria, viruses, and parasites) can easily spread between different individuals through water flow or direct contact, leading to the spread of the epidemic. Even with batch transport, frequent container changes are required, increasing operational costs and the probability of contamination. Second, the environmental control capacity is weak. Diseased fish are sensitive to water quality (dissolved oxygen, ammonia nitrogen content, etc.) due to their weakened state. Traditional containers lack independent oxygenation devices, and relying solely on natural dissolved oxygen in the water is insufficient to meet their needs. Furthermore, there is no water level monitoring function, and the water level is easily caused by bumps during transport, resulting in water levels that are too low (dehydration of diseased fish) or too high (overflow pollution), directly affecting the survival rate. Third, hygiene and disinfection are incomplete. After transportation, pathogens, secretions, or uneaten food may remain on the inner walls of the container. Ordinary rinsing with water is insufficient to completely kill microorganisms. If the container is reused without timely disinfection, it may become a new source of infection. Fourth, it lacks ease of operation. Traditional containers are mostly one-piece designs, which are difficult to open and close. The container needs to be emptied to store and retrieve diseased fish, take samples for observation, or clean up residue, which can easily cause secondary stress or damage. In addition, it lacks an automated control module, requiring frequent manual checks of parameters such as oxygenation and water level, which is time-consuming and labor-intensive.

[0003] Therefore, there is an urgent need for a specialized diseased fish transport equipment with functions such as zoned isolation, environmental control, convenient disinfection, and intelligent management to solve problems such as cross-infection, unstable environment, hygiene hazards, and low operational efficiency in existing technologies.

[0007] As a preferred technical solution of this utility model, each of the openable cover plates is a circular HDPE board with its edge extending outward to form a flange. The flange contacts and seals the upper surface of the box cover through a silicone rubber sealing ring. The edge of the cover plate is provided with a snap-on latch, which includes a female latch fixed to the box cover and a male latch fixed to the cover plate. The openable cover plate and the box cover are fixedly connected by the engagement of the female latch and the male latch.

[0008] As a preferred technical solution of this utility model, the square ultraviolet lamp assembly includes a PVC waterproof shell, with light-transmitting holes evenly opened at the bottom of the shell, and a low-pressure mercury ultraviolet lamp tube encapsulated inside; the shell is fixed to the upper surface of the box cover by bolts, and the shell is installed at a downward angle so that the ultraviolet light beam emitted by the ultraviolet lamp tube covers the lower middle area of ​​the corresponding chamber.

[0009] As a preferred embodiment of this utility model, the oxygenation pipe is a PVC pipe, which is horizontally arranged along the bottom of the corresponding chamber. An air outlet is opened at the top of the oxygenation pipe, and the direction of the air outlet is vertically upward.

Independent and controllable environmental parameters improve survival rate: Each chamber is equipped with an independent oxygenation tube, which connects to an external aerator via a quick-connect connector, allowing for precise adjustment of dissolved oxygen levels in the corresponding area. Simultaneously, a water level gauge monitors the water level in real time, preventing dehydration or overflow. The independent environmental control module ensures stable water quality in each chamber, significantly improving the survival rate of diseased fish during transport. 3. Integrated disinfection function to reduce hygiene risks: A square ultraviolet lamp assembly is fixed to the surface of the lid, and the outer shell is installed at a downward angle, so that the ultraviolet beam can be directed to cover the lower part of the chamber. This allows for rapid disinfection of the chamber before transport or after arrival at the destination, killing any residual pathogens. Combined with the independent opening and closing design of the lid, disinfection operations do not require tilting the chamber, avoiding secondary contamination. 4.

[0014] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0015] In the attached diagram, all identical reference numerals refer to the same components.

[0016] Example 1: Implementation of Basic Structure and Partition Isolation Function like Figure 1-5 As shown, this embodiment provides a partitioned isolation transfer box for diseased fish. The box body 1 is an elongated elliptical shape, and its interior is divided along the length of the box body 1 by two parallel corrugated partitions 2, forming a first chamber 111, a second chamber 112, and a third chamber 113. The inner and outer surfaces of the partitions 2 facing each chamber are tightly fitted to the inner wall of the box body 1, and circular silicone rubber sealing strips 21 are embedded in the edges. These strips are continuously arranged around the circumference of the partitions 2 and are press-fitted to the inner wall of the box body 1 to form a physical sealing barrier, effectively preventing water infiltration and pathogen spread between different chambers.

[0017] Please see Figure 5 The top of the box 1 is sealed with a box cover 12, and square ultraviolet lamp groups 4 are fixed to the upper surface of the box corresponding to the three chambers. The ultraviolet lamp group 4 includes a PVC waterproof shell 41, with light-transmitting holes 43 evenly distributed at the bottom of the shell 41, and a low-pressure mercury ultraviolet lamp tube 42 encapsulated inside; the shell 41 is fixed to the box cover 12 with bolts, and is installed at a downward tilt so that the light beam emitted by the ultraviolet lamp tube 42 covers the middle and lower part of the corresponding chamber (the main activity area of ​​the diseased fish).

[0018] Each chamber has a circular, openable cover 3 at its top opening. The cover 3 is made of HDPE material, with its edges extending outward to form a flange 33. The flange 33 is sealed to the upper surface of the cover 12 by a silicone rubber sealing ring 31. The edge of the cover 3 is also provided with a snap-on latch 32. The latch 32 includes a female latch 321 fixed to the cover 12 and a male latch 322 fixed to the cover 3. The cover 3 is fixedly connected to the cover 12 by the engagement of the female latch 321 and the male latch 322, which facilitates the independent opening and closing of each chamber for the storage or observation of diseased fish.

[0019] Example 2: Verification of Environmental Control and Hygiene Disinfection Functions This embodiment focuses on the environmental control and disinfection functions of the transport box. Each chamber is independently connected to an oxygenation pipe 6 on the inner bottom side of the box 1. The oxygenation pipe 6 is made of PVC and is laid horizontally along the bottom of the corresponding chamber. A vertically upward air outlet 61 is opened at the top. The air inlet passes through the bottom of the box 1 and is connected to an external oxygenator via a quick-connect connector 62. The dissolved oxygen level in each chamber can be independently adjusted.

[0020] Each openable cover 3 is equipped with a water level gauge 5 on its side to monitor the water level in the corresponding chamber in real time, preventing the water level from being too low (dehydration of diseased fish) or too high (overflow pollution) due to bumps. Each chamber is independently equipped with a drain valve 7 on the outer bottom of the tank body 1. The drain valve 7 is a solenoid valve with an inlet connected to an inclined PVC guide pipe 71. The guide pipe 71 is connected to the bottom of the corresponding chamber, which can guide sewage to be discharged quickly. The bottom center of the tank body 1 is also equipped with a sludge discharge port 8 that is connected to each chamber, which is convenient for cleaning uneaten food or excrement at the bottom.

[0021] In addition, the ultraviolet lamp assembly 4, water level gauge 5, oxygenation pipe 6, and drain valve 7 are all connected to the control box 9 on the side of the enclosure 1 via independent waterproof cables. The control box 9 has a built-in PLC controller, which can control the ultraviolet lamp assembly 4 to start and stop disinfection on a timed basis, collect data from the water level gauge 5 and issue warnings, adjust the oxygen supply of the oxygenation pipe 6, and open and close the drain valve 7, so as to realize intelligent management of the transfer process.

[0022] Example 3: Multi-scenario Applicability and Ease of Use Test This embodiment simulates a real-world transport scenario to verify the independent use of the equipment's multiple chambers and its ease of operation. For example, when transporting diseased fish from three different sources, each chamber can be loaded independently and completely isolated by the corrugated partition 2 and sealing strip 21 to avoid cross-infection.

[0023] During operation, any one of the openable covers 3 can be opened individually for the release or sampling of diseased fish without tilting the entire tank, thus reducing secondary stress on the diseased fish. After the transfer is completed, the ultraviolet lamp group 4 is activated through the control box 9 to disinfect each chamber, and then turned off after 30 minutes, which can effectively kill residual pathogens; then the drain valve 7 is opened to quickly drain the sewage through the guide pipe 71, and the residue is cleaned through the slag discharge port 8. The entire process does not require manual handling or turning of the tank, making the operation efficient and hygienic.

[0024] In summary, this utility model effectively solves the problems of cross-infection and unstable environment in traditional transport boxes through partitioned isolation, independent environmental control and intelligent management, and is suitable for the safe transport of diseased fish in various scenarios such as aquaculture and aquatic organism diagnosis and treatment.
