Oxygenation heat preservation device for aquaculture

Abstract

The invention provides an oxygenation heat preservation device for aquaculture, and relates to the technical field of aquaculture. The device comprises a hatching and breeding box and a heat preservation cover. The hatching and breeding box is of a square box-shaped structure, and a control electric box is installed at the front end of the hatching and breeding box; a transparent observation plateis installed at the top of the heat preservation cover, the heat preservation cover is located at the top of the hatching and breeding box, and handles are arranged at the two ends of the top of theheat preservation cover respectively; an oxygenation piece is mounted in the bottom of the hatching and breeding box, and is communicated with an air pipe through a rotary joint; the bottom end of a driving motor is connected with a driving belt, and the other end of the driving belt is connected with the bottom end of the oxygenation piece; and the driving motor drives the oxygenation piece at the bottom of the hatching and breeding box to rotate, air in the oxygenation piece is discharged into water in the hatching and breeding box through air stone, rising bubbles in the water are spiral, the oxygen dissolving effect of the water in the hatching and breeding box is improved, and the sufficiency of dissolved oxygen in the water is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and more specifically relates to an aeration and heat preservation device for aquaculture. Background technique [0002] Aquaculture is a production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. In aquaculture, hatching and raising fish eggs is an important stage. It is necessary not only to ensure the survival rate of fish fry, but also to ensure the hatching and raising rate. Therefore, it is necessary to use hatching to increase oxygen The heat preservation device conducts artificial assisted hatching to ensure that farmers can obtain better benefits in the field of aquaculture. [0003] Aquaculture oxygenation heat preservation device can refer to patent CN207383306U, which mainly includes device outer frame and strip control board, the top of the device outer frame is welded with a hanging frame, and the inner side of the device outer fr...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides an aeration and heat preservation device for aquaculture, to solve the problem that the existing similar aeration and heat preservation devices for aquaculture have poor oxygenation effect on the water body at the edge and need to increase oxygen. Air stones are generally located in the middle of the water body, and it is difficult to effectively adjust and move the air stones required for oxygenation. During the hatching process of fish eggs, fish eggs located at the edge are prone to hypoxia and death, which affects the hatching of fish eggs problem of effect
