Description

Technical Field

[0001] The invention relates to the technical field of life-keeping devices, and in particular to a large yellow croaker life-keeping transportation device and a use method thereof. Background Art

[0002] Large yellow croaker belongs to the order Perciformes, family Sciaenidae, genus Pseudocrocea, and is a local marine fish unique to my country. Large yellow croaker is the single fish with the highest yield and the largest farming scale in my country's marine cage culture. It is one of my country's eight most advantageous export aquatic products, with an annual output value of over 10 billion yuan. Due to overfishing, the wild large yellow croaker population cannot form a fishing season, the number has dropped sharply, and the germplasm resources have declined. Collecting and keeping wild large yellow croaker alive is an important preliminary work for the selection and breeding of large yellow croaker stock. Only by ensuring the survival rate of large yellow croaker capture can the selection and breeding of large yellow croaker stock be effectively carried out. Since wild large yellow croaker mainly lives in water layers below 10 meters deep, suddenly fishing to the surface will cause the fish bladder to swell and die due to pressure changes. At the same time, the scales of large yellow croaker are easy to fall off and are easily damaged in the process of keeping them alive. Wild large yellow croaker is a broad-spectrum carnivorous fish, and is afraid of strong light. It is not easy to be domesticated and fed in cement pools. After the large yellow croaker is caught, transportation equipment is needed for transportation and transfer.

[0003] Traditional transportation devices usually use a simple water pump circulation system, which results in a single and chaotic water flow, making it difficult to simulate the natural water flow environment. In the natural environment, large yellow croaker lives in layered water flow conditions, with different water flow speeds and directions at different depths. This layered water flow can effectively reduce the stress response of fish.

[0004] Existing technologies are unable to provide this multi-level water flow environment, which causes fish to face unsuitable water flow conditions during transportation, increases the intensity of stress response, and ultimately affects survival rate. Summary of the invention

The rotating rod drives the spiral plate to form a spiral water flow by rotating, and the guide plates 1 and 2 are used to guide the water flow to different directions and heights, thereby achieving buffering and stratification of the water flow, so that the water flow inside the transport box presents different speeds and directions at different heights and regions, so as to simulate the water flow of large yellow croaker in a natural environment.

The sunshade is fixed to the outer wall of the transport box by a fixing block and a slider, providing a sunshade function to avoid the influence of external light and temperature on the water in the box. The whole device monitors the water temperature in the transport box through a thermometer, thereby effectively reducing the stress response of the large yellow croaker during long-term transportation and improving its survival rate.

[0016] The present invention provides a large yellow croaker live transport device and a method for using the same. The device has the following beneficial effects:

[0017] 1. The present invention achieves the goal of filtering the water inside the transport box through the cooperation between the water flow buffer component and the filter component. At the same time, through the layered design, the water flow speed and direction in the water tanks at different heights are different, simulating the water flow conditions at different water depths. The simulation of the natural water flow environment helps to reduce the stress response of large yellow croaker during transportation, maintain its normal physiological state and improve the survival rate, and solves the problems of strong stress response and low survival rate of large yellow croaker caused by single water flow and uneven water quality in traditional transportation devices.

[0018] 2. The present invention achieves the convenience of heating or cooling the filtered water to maintain the stability of the water temperature and avoid excessive fluctuations in the water temperature through the cooperation between the filtering component and the temperature control component. It solves the problem of high mortality rate caused by metabolic disorders and decreased immunity of large yellow croaker due to inaccurate water temperature control and large temperature differences in traditional transportation devices. At the same time, under different external ambient temperatures, the water temperature can be effectively adjusted through stable temperature control measures to meet the requirements of different seasons and transportation conditions.

[0019] 3. The present invention achieves the goal of controlling the aeration depth while aerating the interior of the transport box through the cooperation between the aeration component and the adjustment component, ensuring that the dissolved oxygen content in the water body is always maintained within an appropriate range to further improve the survival rate, and solves the problems of stress response and mass death of large yellow croaker due to lack of oxygen due to insufficient dissolved oxygen or uneven dissolved oxygen distribution in traditional transportation devices.

10. A method for using a large yellow croaker alive transport device, according to the large yellow croaker alive transport device according to claims 1-9, characterized in that: A transport box (2) is fixed on the upper surface of the cart (1) to facilitate the overall movement of the device. A water flow buffer component (3) is arranged inside the transport box (2). The water flow buffer component (3) is composed of a spiral plate (302) fixed to the outer wall of a rotating rod (301) and a plurality of guide plates (303) and guide plates (305). The rotating rod (301) drives the spiral plate (302) to form a spiral water flow by rotating, and guide plates (303) and guide plates (305) are used to guide the water flow to different directions and heights, thereby achieving buffering and stratification of the water flow, so that the water flow inside the transport box (2) presents different speeds and directions at different heights and regions, so as to simulate the water flow conditions of large yellow croaker in the natural environment and effectively reduce its stress response. After being buffered, the water flow is extracted by a water pump (402) through an extraction pipe (403) fixed inside the transport box (2) and enters a water tank (401) located on the transport box (2). The top of the water tank (401) is slidably connected to a top plate (405). A slidable filter screen (406) and an activated carbon plate (407) are installed inside the top plate (405). The water is filtered of impurities through the filter screen (406) and further purified through the activated carbon plate (407). The filtered water re-enters the interior of the transport box (2) through a reflux pipe (408). During the reflux process, a flow valve ( 409) can control the flow rate of water to meet different transportation requirements; the temperature control component (5) adjusts the water temperature through the ceramic heating element (501) installed on the outer wall of the top plate (405) and the cooling surface of the cooling plate (502) fixed inside the water tank (401), wherein the cooling plate (502) exchanges heat through the heat sink (503) fixed on the outer wall to ensure that the water temperature is kept within a suitable range for large yellow croaker; during the process of water circulation and temperature stabilization, the oxygen pump (607) of the aeration component (6) transports oxygen to the inside of the transport box (2) through the hose (608), and the oxygen is passed through the aeration component (6) to the inside of the transport box (2). The oxygen in the water enters the water body through the filter (611) fixed on the nozzle (610). At the same time, the nozzle (610) slides and adjusts its position and height through the connecting ring (601) and the connecting rope (602) to control the dissolved oxygen content at different water depths. The cooperation between the fixing rope (612) and the bearing block (613) ensures the stability of the nozzle (610) in the water. The water pump (604) extracts water from the inside of the connecting plate (603) through the water pump pipe (605) and transports it to the three-way valve (609). The three-way valve (609) controls the direction of the water flow to ensure the uniformity of the oxygen distribution in the water body. The motor (702) fixed on the connecting plate (603) drives the winding roller (703) to retract and release the suspension rope (704), so that the nozzle (610) can be flexibly adjusted between different water depths, further optimizing the depth distribution of dissolved oxygen. The sunshade (10) is fixed to the outer wall of the transport box (2) through a fixing block (8) and a slider (9), providing a sunshade function to avoid the influence of external light and temperature on the water body in the box. The entire device monitors the water temperature in the transport box (2) through a thermometer (11), thereby effectively reducing the stress response of large yellow croaker during long-term transportation and improving its survival rate.
