Unmanned aquaculture oxygenation workstation and oxygenating method

Abstract

The invention provides an unmanned aquaculture oxygenation workstation and an oxygenating method. The unmanned aquaculture oxygenation workstation comprises a floating plate, a driving mechanism, an oxygenation mechanism and an oxygen injection mechanism, wherein the driving mechanism is arranged on the upper surface of the floating plate; the oxygen injection mechanism is annularly arranged on the periphery of the floating plate, and comprises a rubber water ring, a floating bucket, a valve, an air guide pipe, an assembly plate, exhaust duckbills and a three-way valve; the rubber water ring is fixedly arranged on the side wall of the floating plate, and the floating bucket is fixedly arranged in the rubber water ring; the oxygen outlet formed in the side wall of the floating bucket is fixedly connected with the oxygen inlet of the assembly plate through the air guide pipe; four exhaust duckbills which are arranged in an annular shape are fixedly arranged at the bottom of the assemblyplate, and each exhaust duckbill is fixedly connected with the oxygen vent formed in the bottom of the assembly plate; and the three-way valve is arranged on the air guide pipe. The unmanned aquaculture oxygenation workstation and oxygenating method have the advantage of increasing the mixing contact area of air and a water body.

Description

technical field [0001] The invention relates to the technical field of aquaculture equipment, in particular to an unmanned aquaculture oxygenation workstation and an oxygenation method. Background technique [0002] There are several methods of oxygenation in pond water, such as chemical oxygenation, mechanical oxygenation, and biological oxygenation. Chemical oxygenation is mainly to artificially put some chemical preparations into the aquaculture water body. After meeting the water, it will chemically react in the water to release oxygen, thereby increasing the content of dissolved oxygen in the water body. Chemical oxygenation agents are generally sodium percarbonate and peroxyamide. , any one of calcium peroxide, hydrogen peroxide and ammonium peroxodisulfide. Mechanical aeration is mainly to increase the dissolved oxygen in the water body by providing high-content water body to the aquaculture water body through fishery machinery or continuously replenishing oxygen to ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing fish pond aerators raise the water through an impeller, stir the water body to produce splashes, and rely on the centrifugal force generated by the rotation to make the upper layer of water diffuse to the surrounding, and the lower layer of water fills up the gap to form a water body with a high oxygen content. After the surface water enters the bottom layer, it can effectively improve the dissolved oxygen status of the bottom water body, but the oxygenation efficiency of most traditional wind wheel aerators is low, and the water body can only be raised by the impeller to increase contact with the air To achieve the purpose of increasing oxygen, the oxygen dissolved in the water body is limited, it is difficult to meet the needs of pond culture to increase production, and it is still prone to high-yield floating heads and hypoxia, resulting in a large number of fish deaths
