Fresh water fish preservation and transportation device

Abstract

The invention belongs to the technical field of live fish transportation devices, and particularly relates to a fresh water fish preservation and transportation device. The device comprises a container fixed to a vehicle, a plurality of air inlet mechanisms are arranged on the container in a matrix shape, and the opening direction of the upper end of an L-shaped air outlet pipe is opposite to the opening direction of an air inlet box; a groove is formed in the bottom of the inner side of the container, the edge of the bottom of the inner side of the container inclines downwards to the groove, and a packing auger is arranged in the groove; the free end of a connecting pipe is connected with a water inlet of a water pump, and the free end of an inverted-U-shaped drainage pipe penetrates through the container and is located above an isolation net plate. The device aims at driving the container to move through the transportation vehicle, oxygenating live fishes in the container by utilizing wind power generated during movement of the container and solving the problem that the energy consumption is huge due to long-time starting of oxygen increasing equipment. Meanwhile, the packing auger is used for transporting precipitation generated in the live fish transporting process, the retention time of the precipitation in a water body is reduced, the survival rate of adult fishes is increased, and the adult fishes are fresher and more alive.

Description

technical field [0001] The invention belongs to the technical field of live fish transportation devices, and in particular relates to a fresh-keeping transportation device for adult freshwater fish. Background technique [0002] With the improvement of the quality of life, consumers have higher requirements for the freshness of aquatic products, so the market share of my country's aquatic products transportation continues to increase. Almost 100% of my country's freshwater fish meets domestic consumption (including Hong Kong, Macao, and Taiwan). Among my country's main agricultural products, meat, fish, eggs, and milk, the total output of aquatic products accounts for 31%, while the output of freshwater fish accounts for 10% of the total output of aquatic products. 30.3%, which plays a key role in the effective supply of aquatic products in the market. As people's demand for fish products tends to be fresh and alive, people pay more and more attention to the preservation and...

[0005] Usually, the oxygenation method of the live fish container is to use air or oxygen inside the fish storage container to inflate the water body to increase oxygenation. Generally, live fish consume a lot of oxygen during long-term and high-density transportation, and a large amount of air or oxygen needs to be supplied. Once the live fish is put into the container, the oxygenation equipment must be turned on all the time to continuously increase the oxygenation of the live fish in the container, which consumes a lot of energy

[0006] At the same time, when the existing water circulation pipeline absorbs the sediment in the water body, it can only absorb the sediment at the inlet of the pipeline, and the sediment absorption efficiency is low, so that the sediment remains in the water body for a long time, causing pollution to the water body, making The survival rate of adult fish decreases, which in turn affects the freshness of adult fish
