Description

Technical Field

[0001] The invention relates to the technical field of aquatic product transportation, and in particular to a fish and shrimp keeping alive device and a use method thereof. Background Art

[0002] At present, the demand for fresh fish and shrimp in the market has shown a significant growth trend. However, the supply of fresh fish and shrimp faces severe challenges of geographical restrictions. Since fresh fish and shrimp need to maintain a certain living environment and temperature conditions, they are prone to death and deterioration during long-distance transportation. Therefore, the transport boxes need to be regularly filled with water and oxygenated during transportation, which increases the difficulty of transportation and is difficult to promote on a large scale in practical applications.

[0003] In order to solve the above-mentioned problems, a Chinese utility model with publication number CN219019976U discloses an aquatic product transport barrel that is convenient for arranging an aeration pipe. The aquatic product transport barrel specifically includes a barrel body, a cover body, and an oxygenation device. The barrel body is provided with a cavity for accommodating aquatic products, and the top of the cavity is open. The cover body is used to control the opening and closing of the cavity. The oxygenation device includes an aeration pipe for transporting oxygen, and the air outlet of the aeration pipe is located in the cavity. The side walls and the bottom of the cavity are provided with grooves for routing the aeration pipe. The aeration pipe is arranged in the groove and extends along the groove. The aeration pipe arranged in this way can evenly distribute oxygen in the cavity, greatly improve the survival rate of aquatic products, and reduce transportation costs. Although the above method can realize oxygen supply for fish and shrimp in the transport barrel during transportation, there are still some problems. First, an oxygenator needs to be added to the transport barrel, which not only increases the overall volume and occupies more transportation space, but also increases energy consumption, thus increasing transportation costs. In addition, the oxygenator on the upper part of the transport barrel makes it impossible to stack the barrels, and the capacity of the transport barrel is limited, making it difficult to carry large-scale transportation of fresh fish and shrimp.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0020] Example 1 A fish and shrimp keeping alive device of this embodiment is shown in FIG. Figure 1 , including multiple outer frames 11, bottom frames 12, top frames 13, inner nets 14, frame inner fixed brackets 15, sealing covers 16 and microporous inner layers 2. Multiple outer frames 11, bottom frames 12 and top frames 13 are enclosed and spliced ​​to form a water tank body 1. The top frame 13 is provided with a take-in and put-out port 151. The frame inner fixed bracket 15 is connected to the inner side of the take-in and put-out port 151. The fixed part of the inner net 14 is connected to the frame inner fixed bracket 15, so that the inner net 14 is fixed in the water tank body 1. The sealing cover 16 is detachably connected to the top end of the frame inner fixed bracket 15. A plurality of air holes are evenly provided on the outer side of the water tank body 1. The inner side of the outer frame 11 is covered with a highly air-permeable and water-tight microporous inner layer 2.

[0021] By providing a water tank body 1 with air holes, and covering the water tank body 1 with a highly air-permeable and water-tight microporous inner layer 2, during the transportation of fish and shrimp, the oxygen in the air can be naturally supplemented into the aquaculture water in the water tank body 1, without the need to supplement oxygenation midway, and without the need to add an oxygenation device, saving the cost of oxygenation during transportation, and also saving the time required for oxygenation; because the microporous inner layer 2 is air-permeable and water-tight, the aquaculture water will not overflow outside the water tank body 1 during transportation, so there is no need to replenish water during transportation, and the cost of changing water is also saved, and the device can be reused after transportation and cleaning, saving water and being environmentally friendly. In addition, the fish and shrimp keeping alive device of the present invention can be stacked and placed in multiple layers, and the structure outside the water tank body 1 occupies less transportation space, thereby increasing the transportation volume of fresh fish and shrimp, and further saving transportation costs. Since the opening of the access port 151 is small, in order to avoid occupying a larger area of ​​the top frame 13, the top frame 13 also has a ventilation effect, thereby increasing the ventilation area of ​​the entire device, and achieving a better oxygen supplement effect. The inner net 14 is provided to facilitate the removal of fish and shrimps, and also to limit the range of their activities, thereby preventing them from touching and damaging the microporous inner layer 2. When in use, the frame is filled with oxygen-enriched clean water after oxygenation, and then fresh fish and shrimps are placed in the inner net 14, and the sealing cover 16 is tightened.

[0022] Preferably, the microporous inner layer 2 is a polytetrafluoroethylene film, and the outer frame 11, the bottom frame 12 and the top frame 13 are all made of a perforated plastic plate. The microporous inner layer 2 made of a polytetrafluoroethylene film can effectively allow oxygen to enter the water tank body 1, while the water in the water tank body 1 flows out and prevents the entry of external pollutants, ensuring that fish and shrimp can breathe sufficient oxygen during long-distance transportation, while maintaining stable water quality. The perforated plastic plate is used as the material of the outer frame 11, the bottom frame 12 and the top frame 13, which has the characteristics of being light, firm and durable, can withstand certain pressure and impact, and protects the internal fish and shrimp from external damage. Moreover, the holes of the perforated plastic plate itself can form multiple evenly distributed air holes on the outside of the water tank body 1. In addition, the plastic material has good corrosion resistance, can resist the erosion of water quality changes, detergents and other chemicals, and prolongs the service life of the device.

[0023] Preferably, the microporous inner layer 2 may also be a polyethylene film with a pore size of 0.1 μm-0.5 μm. The microporous inner layer 2 with a pore size of 0.1 μm-0.5 μm is provided so that air can enter the water tank body 1 through the inner side of the micropores, while the water molecules in the water tank water body cannot penetrate out of the device through the microporous inner layer 2, thus ensuring that sufficient oxygen enters to meet the breathing needs of fish and shrimp, and there is no need to replenish water to the water tank body 1 during transportation.

[0024] Example 2 Due to the presence of the microporous inner layer 2, the interior of the water tank body 1 is connected to the outside air, which also causes the poor thermal insulation performance of the water tank body 1. Therefore, in order to keep the water temperature in the water tank body 1 at a suitable temperature for fish and shrimp transportation, this embodiment also includes a constant temperature adjustment component, see the attached Figure 2 A base 31 is provided at the bottom of the water tank body 1, and a constant temperature adjustment component is arranged in the base 31. The constant temperature adjustment component includes a semiconductor refrigerator 32, a refrigerator bracket 33, a first heat conductive plate 34, a second heat conductive plate 35, a first heat exchanger 36 and a second heat exchanger 37. The semiconductor refrigerator 32 is embedded in the refrigerator bracket 33, the first heat conductive plate 34 is arranged on the side of the refrigerator bracket 33 close to the water tank body 1, and the second heat conductive plate 35 is arranged on the side of the refrigerator bracket 33 away from the water tank body 1. The first heat conductive plate 34 and the second heat conductive plate 35 are respectively attached to the cold end and the hot end of the semiconductor refrigerator 32, the first heat exchanger 36 is arranged on the first heat conductive plate 34, and the second heat exchanger 37 is arranged at the bottom of the second heat conductive plate 35.

[0025] By setting the thermostatic adjustment component, the temperature in the water tank body 1 is always within the temperature range that fish and shrimp are adapted to, and fish and shrimp can better adapt to changes in the external environment during long-distance transportation, reduce the stress response and death risk of fish and shrimp caused by temperature fluctuations, and improve the safety and stability of transportation. The semiconductor refrigerator 32 is used as a refrigeration element, which has the advantage of small volume and can achieve efficient heat energy conversion in a small space, so that the space occupied by the thermostatic adjustment component as a whole is small, thereby increasing the number of stacking layers of the fish and shrimp keeping alive device of this embodiment, and further increasing the transportation volume of fresh fish and shrimp. By setting the first heat conducting plate 34 and the first heat exchanger 36 at the cold end of the semiconductor refrigerator 32, the heat exchange efficiency is enhanced, and the cold energy generated by the semiconductor refrigerator 32 can be effectively transferred to the water tank body 1 through the microporous inner layer 2 at the bottom of the water tank body 1, so as to achieve rapid temperature adjustment, ensure that the water temperature in the water tank body 1 is kept within the range suitable for fish and shrimp, thereby greatly improving the survival rate and quality of fish and shrimp. The second heat exchanger 37 and the second heat conducting plate 35 are arranged at the hot end of the semiconductor refrigerator 32 to dissipate heat from the semiconductor refrigerator 32 and ensure stable operation of the semiconductor refrigerator 32 .

[0026] Furthermore, the constant temperature adjustment component includes a cooling fan 38 and a heat dissipation fan 39. The first heat exchanger 36 is provided with a plurality of first fins, and the second heat exchanger 37 is provided with a plurality of second fins. The cooling fan 38 is arranged between the water tank body 1 and the first heat exchanger 36. The air outlet direction of the heat dissipation fan 39 is arranged parallel to the gap between the second fins. The heat dissipation fan 39 is arranged on the outside of the base 31. The bottom of the base 31 is provided with a heat insulation buffer pad 4, and the top of the top frame 13 is provided with a fixing block 5 matching the shape of the base 31.

[0027] The first heat exchanger 36 is provided with a plurality of first fins, which greatly increases the heat exchange area and improves the heat exchange efficiency, so that the refrigeration fan 38 can more effectively transfer the cold to the water in the water tank body 1 through the microporous inner layer 2 at the bottom of the water tank body 1, thereby improving the efficiency of temperature regulation and ensuring that the water tank body 1 maintains a constant temperature environment. The heat dissipation fan 39 is arranged on the outside of the base 31. This layout not only optimizes the heat dissipation conditions of the semiconductor refrigerator 32, but also reduces the influence of heat dissipation on the temperature in the water tank body 1, so that the cold air supplied to the water tank body 1 and the hot air generated by the semiconductor refrigerator 32 do not interfere with each other, thereby improving the working efficiency and stability of the constant temperature adjustment component. By arranging a heat insulation cushion 4 at the bottom of the base 31, the heat transfer between the base 31 and the outside of the device is effectively isolated. When the fish and shrimp keeping alive device of this embodiment is stacked and used, the temperature influence between the fish and shrimp keeping alive devices stacked up and down is reduced, a more stable constant temperature effect is maintained, and energy consumption is reduced. By providing a fixing block 5 matching the shape of the base 31 on the top of the top frame 13, during transportation, the matching of the fixing block 5 and the base 31 can effectively prevent the two stacked fish and shrimp keeping devices from shaking or shifting, thereby protecting the fish and shrimp inside from harm.

[0028] Preferably, the thermostatic adjustment component further includes a first temperature sensor and a second temperature sensor, the first temperature sensor is arranged between the bottom frame 12 and the first heat conducting plate 34 , and the second temperature sensor is arranged in the water tank body 1 .

[0029] The first temperature sensor is arranged between the bottom frame 12 and the first heat conducting plate 34 to monitor the temperature of the cold end of the semiconductor refrigerator 32 in real time, while the second temperature sensor is arranged in the water tank body 1 to monitor the actual temperature of the environment in which the fish and shrimp are located in real time. The output power of the semiconductor refrigerator 32 and the working state of the cooling fan 38 and the heat dissipation fan 39 are adjusted by obtaining the temperatures of the two places by the first temperature sensor and the second temperature sensor, so as to ensure that the temperature in the water tank body 1 is always kept within the suitable range for the fish and shrimp, and avoid the stress reaction and death risk of the fish and shrimp caused by temperature fluctuations. When the temperature is within the set range, the semiconductor refrigerator 32, the cooling fan 38 and the heat dissipation fan 39 stop working, so as to avoid unnecessary energy consumption and reduce the transportation cost. It is also suitable for the transportation of various fish and shrimp products with different temperature adaptability ranges.

[0030] Preferably, it also includes an environmental detection component, which includes an ammonia nitrogen sensor, a salinity sensor and a water level sensor. The detection probes of the ammonia nitrogen sensor and the salinity sensor are both arranged in the water tank body 1, a water level detection box is provided on the inner side of one of the outer frames 11, a water hole is provided at the bottom of the water level detection box, the water level sensor is arranged in the water level detection box, an opening is provided on one side of the water level detection box, and the microporous inner layer 2 covers the opening.

[0031] The ammonia nitrogen sensor can monitor the ammonia nitrogen content in the water tank body 1 in real time to prevent fish and shrimp from being poisoned or dying due to excessive ammonia nitrogen. The salinity sensor is used to monitor the salinity level in the water tank body 1 to ensure that the water quality meets the survival needs of fish and shrimp. When the ammonia nitrogen content or salinity level in the water tank body 1 exceeds the set value, the transport personnel are promptly reminded to perform water changes and other operations to reduce the losses caused by the death of fish and shrimp.

[0032] A water level sensor is provided to monitor whether the water level in the water tank body 1 is normal, so as to avoid the death of fish and shrimp due to lack of water. A water level detection box is provided to fix the water level sensor, and a water hole is provided at the bottom of the water level detection box so that the water level in the box is consistent with the water level in the water tank body 1. This fixing method avoids the water tank body 1 being affected by various external forces during transportation, such as vibration, bumps, etc., which may cause partial water level changes and cause the water level sensor to be triggered incorrectly.

[0033] Preferably, it also includes a waterproof light belt 8 and a light belt controller; the waterproof light belt 8 is arranged around the top of the outer frame 11, the waterproof light belt 8 is electrically connected to the light belt controller, and the light belt controller is arranged on the top frame 13.

[0034] By wrapping the waterproof light strip 8 around the top of the outer frame 11, a suitable lighting environment can be provided for the fish and shrimp in the water tank body 1, thereby improving their survival rate and quality. A light strip controller is provided to adjust the brightness and color temperature of the waterproof light strip 8 to meet the different lighting requirements of different types of fish and shrimp.

[0035] Preferably, it further comprises a plurality of microporous vibration sheets 6 , which are evenly distributed and fixed on the bottom frame 12 , and the vibration ends of the microporous vibration sheets 6 are located on the inner side of the microporous inner layer 2 .

[0036] By setting the vibrating end of the microporous vibration plate 6 to be located on the inner side of the microporous inner layer 2, when the microporous vibration plate 6 is working, tiny vibrations are generated, and these vibrations are transmitted to the aquaculture water in the water tank body 1, thereby driving the flow of the water body, increasing the dissolved oxygen content in the water, avoiding the occurrence of dead zones in the water tank body 1, thereby avoiding the occurrence of local hypoxia leading to the death of fish and shrimp, and preventing the accumulation of harmful substances in the water body. Since the vibration generated by the microporous vibration plate 6 is a weak vibration, it will not disturb the activities of fish and shrimp, and can help fish and shrimp adapt to environmental changes during transportation and reduce the occurrence of stress reactions. By setting a plurality of microporous vibration plates 6 evenly distributed on the bottom frame 12, it is ensured that vibrating water flow can be generated for most of the water in the entire water tank body 1, further increasing the dissolved oxygen content in the water.

[0037] Furthermore, it also includes a plurality of liquid baffles 7, which are evenly distributed on the top of the water tank body 1, and the liquid baffles 7 are opposite to the microporous vibrating plate 6 in the upper and lower parts, and the liquid baffles 7 are of a corrugated structure.

[0038] During operation, due to the presence of the microporous inner layer 2, the water tank body 1 is not airtight, so the evaporation of water is inevitable. At the same time, due to the work of the microporous vibrating plate 6, atomized water vapor will be generated, which will accelerate the evaporation process. Therefore, the present embodiment sets a plurality of liquid baffles 7 on the inner side of the top of the water tank body 1. When the atomized water vapor contacts the liquid baffles 7 and is cooled, it liquefies into water droplets and eventually slides into the water tank body 1, thereby avoiding the change of the environment caused by the drop in water level and the triggering of the water level sensor. The liquid baffle 7 adopts a metal baffle with a corrugated structure, and the corrugated structure can also promote the merging and enlargement of droplets. When multiple small droplets meet on the liquid baffle 7, they will converge together along the corrugated convex structure to form larger droplets, making it easier for larger droplets to slide under the action of gravity, thereby further improving the drainage efficiency of the liquid baffle 7.

[0039] This embodiment also provides a method for using the fish and shrimp keeping alive device, the method comprising the following steps: injecting oxygen-enriched purified water into the water tank body, stocking fresh fish and shrimp in the inner net, and installing a sealing cover; During transportation, oxygen in the air is naturally replenished into the water in the water tank through the air holes and the microporous inner layer.

[0040] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
