Description

Technical Field

[0001] This utility model relates to the field of oxygen release technology, and in particular to an oxygen release device for fish fry cultivation. Background Technology

[0002] During the fish fry rearing and breeding process, weather changes, especially cloudy days, and low air pressure lead to low oxygen concentration in the pond and low oxygen content in the water. In the early morning and evening, the light is weak, photosynthesis is weak, and the oxygen production is less than the oxygen consumption of respiration, which affects the normal growth and reproduction of fish fry, resulting in a reduction in the number of fish fry and affecting the normal supply of fish fry.

[0003] For example, the utility model patent with authorization announcement number CN205082482U discloses an oxygen release device for fish fry cultivation. Its base is fixed to the side wall of the water tank, and the lower part of the base is supported and fixed by three support legs. The water tank is equipped with a water supply rod. The upper part of the water supply rod is connected to a water spray pipe, the bottom of the water supply rod is connected to a filter head, and the top of the water supply rod is connected to a motor. The water spray pipe is fixed at an angle on the water supply rod. However, it only uses the water spray pipe to spray outward to improve the circulation of water and complete the mixing of water with oxygen in the air. The oxygen release mechanism is simple and it is difficult to meet the oxygen demand. In view of this, an oxygen release device for fish fry cultivation is proposed. Utility Model Content

[0028] Working principle: In the idle area of ​​this device, connect all the above-mentioned components, which are referred to as structural parts. The specific connection method should refer to the working principle below and complete the connection in the order of operation of each component. The detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and will not explain it again. When using this device, first fix the mounting base 1 through the external fixing mechanism: the suction cup 7 on the fixing plate 8 is attached to the wall of the cultivation pool.

The oxygen enters the hollow rotating shaft 28 through the air guide hole 27, then flows into the connected hollow stirring rod 25, and finally sprays out fine bubbles from the air jet pipe 26. The bubbles diffuse with the water flow, increasing the contact time with the water and improving dissolved oxygen efficiency. In the protective mechanisms at both ends of the lifting plate 3, the protective net 15 fixed by the bracket 14 forms a barrier to prevent the fish fry from being caught in the rotating agitator 25, ensuring the safety of the fish fry.
