Live fish oxygenation device for large yellow croaker relay culture

Abstract

The invention relates to the technical field of live fish oxygenation devices, in particular to a live fish oxygenation device for large yellow croaker relay culture. The live fish oxygenation device comprises a floating ball ring, a positioning and supporting assembly is mounted on the floating ball ring, and an oxygenation assembly is mounted on the positioning and supporting assembly. The floating ball ring can be used for positioning the positioning and supporting assembly, an upper adapter rod and a lower adapter rod are arranged to be of an L-shaped structure, so that the placement stability of the positioning and supporting assembly in water is high, the work and operation stability of the oxygenation assembly in water can be high through the positioning and supporting assembly, and the use safety of oxygenation is improved; and the oxygenation effect of a water body can be effectively improved through rotation of an oxygenation impeller, oxygen-enriched water on the upper layer and the lower layer can be pushed to the outer side through upper water pushing blade plates and lower water pushing blade plates which are arranged in a staggered mode, the oxygenation rate is increased, the structure is simple and reliable, and the using effect is good.

Description

technical field [0001] The invention relates to the technical field of live fish oxygenation devices, in particular to a live fish oxygenation device for relay breeding of large yellow croakers. Background technique [0002] The live fish transport ship is a very important means of transportation and temporary breeding of large yellow croaker in the large yellow croaker relay breeding mode. At present, the oxygenation device on the live fish transport ship used for the transfer of large yellow croaker uses a single oxygenation impeller to increase oxygenation, so that the overall oxygenation efficiency is low, and the placement stability of the oxygenation device is low during the hull driving process , therefore need a kind of live fish aeration device that is used for large yellow croaker relay culture to improve above-mentioned problem. Contents of the invention [0003] The object of the present invention is to provide a live fish oxygenation device for relay culture ...
