A kind of cage conveniently used for increasing oxygen in aquaculture

Abstract

The invention discloses a net cage for convenient aeration in aquaculture, which comprises a floating bar, a first air bag and a hose. A net frame is installed under the floating bar, and load-bearing arms are arranged on both sides of the floating bar, and The surface of the load-bearing arm is installed through a column, and the inside of the column is embedded with a rotating shaft, and a connecting rod is installed under the rotating shaft, the end of the connecting rod is equipped with a paddle, and the upper end of the rotating shaft is installed outside There is a rotating disk, and the outer side of the rotating disk is provided with a limit groove, the lower surface of the first air bag is penetrated by the intake pipe, and the lower end of the intake pipe is connected with a three-way valve, and the output end of the three-way valve is installed with an air delivery pipe , and the end of the air pipe is inserted into the inside of the screen frame. The net cage for aquaculture is convenient for increasing oxygen. When the second air bag is squeezed, it plays the role of sending air to the first air bag. When the first air bag is squeezed, it plays the role of sending oxygen to the inside of the screen frame. function, thereby increasing the oxygen content inside the cage.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a net cage conveniently used for increasing oxygen in aquaculture. Background technique [0002] With the improvement of national economic power, more and more attention is paid to the quality of meat, and the amount of aquatic meat on the table is gradually increasing. When aquaculture is carried out, in order to reduce the cost of breeding and improve the quality of fish, farmers use net frames to put them in reservoirs, In lakes and shallow seas, the natural environment makes fish grow healthier. The existing aquaculture net cages are convenient for centralized management when they are placed in a centralized manner, but fish are extremely prone to hypoxia. When hypoxia occurs, the existing methods are as follows: [0003] 1. Drive the boat to drag the cage, so that the cage moves in the water area and exchanges places, so that the change of the water area plays the role ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of net box for aquaculture that is convenient for increasing oxygen. It does not need to install an external air pump for oxygen supply, and can be used independently in water areas, which is convenient for independent use, so as to solve the problems raised in the above-mentioned background technology.
