Description

Technical Field

[0001] This utility model relates to the field of live fish transportation technology, specifically a water quality control device for transporting live red-eyed trout. Background Technology

[0002] Currently, the live transport of red-eyed trout faces multiple technical challenges, especially during long-distance transport. Problems such as water quality deterioration and environmental stress often lead to a significant decrease in survival rates. Specifically, during transport, the metabolic activities of red-eyed trout produce pollutants such as feces and uneaten food, leading to the accumulation of harmful substances such as ammonia nitrogen and nitrite in the water. At the same time, dissolved oxygen levels drop rapidly due to fish respiration and the decomposition of organic matter. Traditional transport devices are unable to continuously maintain water cleanliness and dissolved oxygen balance, easily causing fish hypoxia or poisoning, resulting in a decrease in fish survival rates during transport. Furthermore, red-eyed trout are quite sensitive to environmental changes. Factors such as bumps during transport, water temperature fluctuations, and water quality deterioration can cause stress responses, manifesting as agitation, increased mucus secretion on the body surface, and decreased immunity, which can lead to disease or even death. In addition, the starting, stopping, and bumping of transport vehicles can cause violent shaking of the water, creating waves that impact the red-eyed trout, exacerbating their energy consumption and even causing mechanical damage due to collisions with container walls, further reducing survival rates.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Red-eyed trout, an important freshwater economic fish in my country, plays a vital role in aquaculture and market circulation due to its tender flesh and strong adaptability. With the large-scale development of aquaculture and frequent cross-regional trade, the demand for live transportation of red-eyed trout is increasing, and the survival rate during transportation directly affects economic benefits and industrial development.

[0027] Due to the limitations of existing technologies in maintaining water cleanliness and dissolved oxygen balance, as well as the susceptibility to stress and strong wave impact during transportation, please refer to... Figures 1-5This embodiment provides a water quality control device for the live transport of red-eyed trout. It ensures water cleanliness and dissolved oxygen levels, improving fish survival rates. During water circulation, a slow-release agent like fish-safe is added to alleviate stress caused by transport. It also reduces wave activity in the internal water during transport, further enhancing fish survival. The device includes a transport box 1 and a lid 2 covering the top of the transport box 1. An oxygenation component 3 and a water treatment component 4 are installed on the two sides of the bottom of the transport box 1, respectively. A dosing component 5 is installed on the water treatment component 4. A monitoring component 6 is installed on the side wall of the transport box 1. The rear of the transport box 1 has a sealed fish outlet 7. By integrating the oxygenation component 3, water treatment component 4, dosing component 5, and monitoring component 6 onto the transport box 1, functional synergy is achieved, improving water quality control efficiency. The sealed fish outlet 7 at the rear of the transport box 1 facilitates safe unloading and reduces fish damage during the unloading process.

[0028] The existing water circulation filtration function of the transport equipment is rudimentary, resulting in poor filtration efficiency. Furthermore, cleaning or replacing the filter components is inconvenient, and blockages can easily disrupt water circulation, leading to water quality deterioration. For solutions to this problem, please refer to [the relevant documentation / reference]. Figure 2 and Figure 5 The water treatment component 4 includes a water pump 41 installed on one side of the bottom of the transport box 1. The inlet of the water pump 41 is connected to the bottom of the transport box 1 via a water pumping pipe 42. A chiller 43 is connected to the top of the water pump 41 via a pipe, and a filter unit 44 is connected to the top of the chiller 43 via a pipe. Both the chiller 43 and the filter unit 44 are installed on one side of the transport box 1, and the bottom of the filter unit 44 is connected to the transport box 1. Specifically, the filter unit 44 includes a filter box 441 installed on one side of the transport box 1. A pull plate 442 is inserted into the filter box 441, and the side wall of the pull plate 442 is sealed to the filter box 441 by bolts. A filter element 443 is provided inside the pull plate 442. The bottom of unit 1 is connected to transport box 1 via water outlet pipe 444; the water treatment component 4 achieves integrated water circulation, cooling and filtration through a series design of "water pump 41-chiller 43-filter unit 44": water pump 41 draws sewage from the bottom of the tank, the water temperature is adjusted by chiller 43 and then enters filter unit 44 for purification, and then flows back to transport box 1 to ensure continuous and stable water quality; the filter unit 44 adopts a pull-out plate 442 structure, and the pull-out plate 442 is connected to filter box 441 by bolt sealing, which facilitates quick removal of filter element 443 for cleaning or replacement, avoiding transportation interruption due to maintenance; the filter element 443 can specifically remove residual feed, feces and some harmful substances in the water, improving the purification effect.

[0029] Red-eyed trout are quite sensitive to environmental changes. Factors such as bumps during transport, fluctuations in water temperature, and deterioration in water quality can cause stress responses, manifesting as restlessness, increased mucus secretion, and decreased immunity, which can lead to disease and even death. For more information on this issue, please refer to [link / reference needed]. Figure 5The dosing assembly 5 includes a medicine chamber 51 installed on top of the filter box 441. The medicine outlet pipe at the bottom of the medicine chamber 51 is connected to the filter box 441, and a solenoid valve 52 is installed on the medicine outlet pipe. The medicine chamber 51 is connected to the filter box 441, and water circulation can be used to evenly carry slow-release agents such as fish anthelmintic into the water body to avoid excessive local concentration. The solenoid valve 52 on the medicine outlet pipe can realize automatic dosing, accurately control the concentration of medicine, and effectively alleviate the transportation stress of red-eyed trout.

[0030] Existing oxygenation devices are mostly single-point or linear oxygenation devices, resulting in uneven bubble distribution. This easily leads to localized insufficient dissolved oxygen within the transport container and has low oxygenation efficiency, making it difficult to meet the high oxygen demand of red-eyed trout during long-distance transport. To address this issue, please refer to... Figure 4 The oxygenation component 3 includes an air pump 31 installed on one side of the bottom of the transport box 1. The air pump 31 is connected to an air pipe 32, and the air pipe 32 is connected to multiple annular pipes 33 located inside the transport box 1. Multiple air bubbles 34 arranged in a ring are installed on the annular pipes 33. The air pump 31 is connected to multiple annular pipes 33 through the air pipe 32. The air bubbles 34 on the annular pipes 33 are arranged in a ring, which can evenly release microbubbles into the transport box 1, greatly improve the dissolved oxygen diffusion range, and avoid local hypoxia. The layout of multiple annular pipes 33 is adapted to the spatial structure of the transport box 1, especially ensuring the dissolved oxygen level in the bottom area of ​​the box, meeting the respiratory needs of red-eyed trout in high-density transportation.

[0031] Traditional transportation relies on regular manual monitoring of water temperature and dissolved oxygen levels, which is inefficient and cannot provide real-time updates on water quality changes. This can easily lead to fish deaths due to untreated or excessive levels of these indicators. For more information on this issue, please refer to [link / reference needed]. Figure 3 The monitoring component 6 includes a controller 61 installed on the side wall of the transport container 1, as well as multiple dissolved oxygen sensors 62 and water temperature sensors 63. The controller 61 is connected to the dissolved oxygen sensors 62 and water temperature sensors 63 via wires. The multiple dissolved oxygen sensors 62 and water temperature sensors 63 can monitor the water quality indicators of different areas inside the transport container 1 in real time. The data is transmitted to the controller 61 for centralized display, which makes it easy for transport personnel to intuitively understand the environmental status. The controller 61 can serve as a data hub, providing a basis for subsequent automatic control, realizing a "monitoring-feedback" closed loop, and improving the accuracy of control.

[0032] Furthermore, a heater 8 is also installed inside the transport box 1; the heater 8 works in conjunction with the chiller 43 to achieve bidirectional water temperature regulation, ensuring that the water temperature remains stable within the suitable range for red-eyed trout during transportation, adapting to different seasons and regional transportation environments.

[0033] Traditional transport containers lack wave-damping structures, and the bumps and jolting during transport can cause violent water movement, leading to injuries to the red-eyed trout from collisions with the container walls or excessive energy expenditure. For solutions to this problem, please refer to [link / reference needed]. Figure 3Multiple equally spaced inserts 9 are fixed on the inner wall of the transport box 1, and a wave deflector 10 is inserted between two opposite inserts 9. A gap is left between the wave deflector 10 and the bottom of the transport box 1. The multiple equally spaced wave deflectors 10 can effectively block water fluctuations, reduce wave intensity, and reduce mechanical damage and energy consumption of the red-eyed trout. The wave deflectors 10 are inserted into the inner wall of the transport box 1 through the inserts 9, making installation and disassembly convenient. The number of wave deflectors 10 can be adjusted according to the transport distance or the degree of bumps. The gap left between the wave deflectors 10 and the bottom of the box does not affect the fish's activity space.
