Description

Technical Field

[0001] The utility model relates to the field of refrigerated cabins, in particular to a marine refrigerated cabin for fishery transportation. Background Art

[0002] Refrigerated holds used on fishing vessels are often called fish holds or cold storage holds. These holds are usually equipped with refrigeration equipment and are used to store caught fish and other seafood to ensure they maintain their freshness and quality. Refrigerated holds on fishing vessels usually have the function of maintaining a constant temperature to ensure that the stored seafood does not rot or spoil.

[0003] In order to better store seafood, it is necessary to use a marine refrigeration cabin for fishery transportation. For example, the prior art Chinese patent announcement number "CN116767480A" discloses a low-temperature refrigeration cabin for marine fishing vessels, including a refrigeration cabin and a flat-plate freezing rack arranged in the refrigeration cabin, the flat-plate freezing rack includes a bracket and a freezing flat plate, the freezing flat plate is arranged in the bracket along the longitudinal interval, the freezing flat plate is provided with a freezing row pipe, a horizontal lifting plate is provided under the freezing flat plate, and air avoidance holes are arranged on the freezing flat plate at intervals, a longitudinal top plate is provided on the horizontal lifting plate, the longitudinal top plate is located in the air avoidance holes and slidably cooperates with the air avoidance holes, a manual lifting mechanism that can lift the horizontal lifting plate up and down is connected to the bottom of the horizontal lifting plate, when the horizontal lifting plate is lowered to the bottom of the stroke, the longitudinal top plate is located in the avoidance hole, and the top end of the longitudinal top plate is retracted into the air avoidance hole, when the horizontal lifting plate is lowered to the top of the stroke, the longitudinal top plate is located in the avoidance hole, and the top end of the longitudinal top plate protrudes out of the air avoidance hole. The invention has a compact structure, a uniform temperature in the cabin, and is convenient to remove the fish tray, which is beneficial to improving the unloading speed of the catch.

[0004] Some fishing transport ships use refrigerated tanks to store seafood through in-cabin refrigeration.
