An emergency aeration and oxygenation system

Abstract

The invention relates to an emergency aeration and oxygenation system, comprising an emergency aeration device, the emergency aeration device includes a water pump, and the upper end of the water pump is fixedly connected with a deflector; There are several diversion openings; the Venturi jet is set inside the deflector, and its central part is connected with the umbilical cable. The umbilical cable is a hollow cable, and the oxygen source is connected to the outside, and can withstand the gravity of the emergency aeration device; the Venturi jet The lower end communicates with the outlet of the water pump, and the upper end corresponds to and communicates with the diversion port one by one. The invention monitors the change trend of dissolved oxygen in the water body through the dissolved oxygen monitoring probe in the breeding pond. When the dissolved oxygen concentration in the water is lower than the safe range, the emergency aeration device will be automatically released into the breeding water body, and spray high Dissolved oxygen water, in order to achieve the purpose of increasing oxygen, adopts automatic setting and is automatically released through the dissolved oxygen monitoring system to reduce the labor cost of personnel operation.

Description

technical field [0001] The invention relates to an aeration and oxygenation device for aquaculture, in particular to an emergency aeration and oxygenation system. Background technique [0002] At present, with the increase in the demand for aquatic products, the density of aquatic product farming is also getting higher and higher, including industrial farming, traditional pond farming, cage farming, fish labor ship farming, etc. The higher the breeding density, the greater the risk and the greater the water body's bearing capacity. Frequent breeding accidents due to lack of oxygen will cause economic losses to farmers. [0003] The emergency measures of most aquaculture enterprises are backup generators, but in some special cases, a single backup generator is not enough to solve practical problems, such as sudden cyanobacteria and algae blooms such as large-scale reservoir aquaculture and cage aquaculture. The death and decomposition of some algae will quickly consume disso...
