Description

Technical Field

[0001] This utility model relates to the field of fish transportation, and in particular to a lid structure and insulated box for transporting live fish. Background Technology

[0002] During long-distance or short-distance transportation, live fish easily generate a large amount of foam on the water surface due to fish metabolism, excretion, and water movement. This foam is mainly composed of a mixture of protein, mucus, bacterial clumps, and air. Once it accumulates, it quickly forms a dense layer on the water surface, blocking oxygen exchange between the air and the water, leading to a decrease in dissolved oxygen levels, causing fish to surface for air due to oxygen deprivation, and even death. At the same time, the decomposition of organic matter in the foam causes a sharp increase in indicators such as ammonia nitrogen and nitrite in the water, deteriorating water quality and further reducing the survival rate of live fish.

[0003] Existing insulated boxes for transporting live fish mostly use single-layer flat lids or simply raised edges, which only serve to keep the water warm, prevent dust and splashes, but cannot effectively isolate foam on the water surface. Some technical solutions attempt to add horizontal foam baffles or inclined deflectors inside the box, but the structure is complex, has many dead corners, is difficult to clean, and the foam is still in the same water space as the fish, so the isolation effect is limited.

It provides a lid structure and a thermal box for transporting live fish, which is simple in structure, easy to clean, and can effectively isolate foam from fish.

[0005] To solve the above-mentioned technical problems, this utility model provides a lid structure for a live fish transport insulated box, including a lid body and an isolation structure disposed in the inner layer of the lid body; the isolation structure protrudes outward along the height direction to form a boss; the boss includes two channels, which are located inside the boss and together form a sealed cavity within the boss; the channels include through holes, and the cavity communicates with the outside through the through holes.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0029] refer to Figures 1-7 This embodiment provides a lid structure 1 for a live fish transport insulated box, including a lid body 101 and an isolation structure 102 disposed in the inner layer of the lid body 101 (e.g., Figure 1The isolation structure 102 is integrally formed on the inner layer of the box cover body 101. The isolation structure 102 protrudes outward along the height direction to form a boss 103 (e.g., Figure 3 The boss 103 includes two channels 104 (e.g., Figure 4 The two channels 104 are located inside the boss 103, and the two channels 104 together form a sealed cavity portion 105 on the boss 103 (e.g., Figure 6 , Figure 7 The channel 104 includes a through hole 107, and the cavity portion 105 is connected to the outside through the through hole 107.

[0030] During transportation, live fish generate foam, which can affect the fish's respiration and water quality. Therefore, in this embodiment, a cavity 105 is provided in the inner layer of the lid structure 1, which is equivalent to the inner surface of the lid being submerged in water. Water and foam can enter this cavity 105, isolating the foam from contact with the fish. Specifically, through the setting of the boss 103, which extends below the water surface, foam can enter the cavity 105 with the water flow through the through hole 107, while the fish are blocked under the boss 103, achieving physical isolation and preventing foam from entering the fish area.

[0031] In this embodiment, as Figure 4 The channel 104 extends outward in a spiral manner from the center in the inner plane of the box cover body 101 (or in the same plane). The spiral guide can guide the water surface to rotate, so that the foam gathers in the channel 104 along the spiral direction, thereby improving the isolation efficiency.

[0032] The two channels 104 have opposite spiral directions. The two channels 104 intersect at at least one intersection point, thereby forming a continuous and interconnected cavity portion 105 inside the boss 103. This cavity portion is formed by the interconnection of the two channels 104, allowing foam to be guided to the intersection point once it enters either channel 104, facilitating subsequent unified discharge. The channels 104 are arranged with equal spiral widths to ensure uniform foam flow resistance and prevent localized blockages.

[0033] In this embodiment, the boss 103 further includes two flow channels 106 (e.g., Figure 1 The two flow channels 106 are formed by the indentation of the end face of the boss 103, and the direction of the two flow channels 106 is consistent with the spiral direction of the two channels 104 (e.g., Figure 4 The two flow channels 106 are interconnected at at least one intersection point, thereby forming a continuous and connected flow channel portion within the end face of the boss 103. By providing flow channels, water agitation can be prevented.

[0034] The spiral flow channel 106, once completed, forms a multi-stage water flow path at the end face of the boss 103, which significantly increases the local flow resistance of the water body. This can quickly reduce the violent fluctuations generated during transportation to a slow flow, prevent water from overflowing, and maintain a stable liquid level inside the tank.

[0035] The lid structure 1 provided in this embodiment is mainly used for closing a thermal box for transporting live fish (such as...). Figure 5 Specifically, the insulated box includes a box body 2 and a box cover structure 1; the box body 2 stores water, the box cover structure 1 covers the box body 2, the boss 103 is submerged in water, and the through hole 107 of the channel 104 is submerged in water (e.g., Figure 6 ).

[0036] The use of the insulated box is as follows: Filling the box with fish: Place the fish and water into the box body 2; Closing the box: Align the box lid structure 1 with the top opening of the box body 2 and press it down vertically to close the box body 2; Deflating the foam: During transportation, the foam gathers in the cavity part 105 along the through hole 107.

[0037] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
