Inflation oxygenation and water saving type temperature-controllable aquatic animal incubation device

Abstract

The invention discloses an inflation oxygenation and water saving type temperature-controllable aquatic animal incubation device which comprises a conical incubation barrel located in a supporting barrel. The conical incubation barrel contains water for incubation and fertilized eggs. A plug at the conical head end of the conical incubation barrel isolates water for incubation from liquid in the supporting barrel, an air supply guide pipe penetrates through the plug, the conical head end of the air supply pipe is connected with an air chamber in the incubation barrel, the far-conical-head end extends out of the supporting barrel and is provided with an air pump, an air amount adjusting valve is arranged between the air pump of the air supply pipe and the incubation barrel, a heating bar can be arranged in the supporting barrel, and the heating bar is connected with a power source. On the basis of the principle that inflation oxygenation are carried out on the bottom of an incubation facility, oxygen needed during aquatic animal fertilized egg incubation is ensured, the problems that a filter net is likely to be blocked, water overflows and small aquatic animals flee in the film outgoing period are solved, then a temperature control device is adopted to ensure that the incubation environment temperature is constant, and the problem that aquatic animal incubation is likely to be affected by weather variations is solved.

Description

technical field [0001] The invention relates to the field of aquatic animal hatching, in particular to an aeration-increasing, water-saving, temperature-controllable aquatic animal hatching device. Background technique [0002] Oxygen and temperature are two key factors affecting the hatching effect of aquatic animals. [0003] At present, the existing aquatic animal hatching devices, whether it is a hatching ring, a hatching tank or a hatching barrel, in order to ensure that the eggs or embryos are always in an environment with sufficient oxygen during the hatching process, they all adopt the method of imitating the flowing water environment of a river and constantly changing the hatching water. Way. [0004] The outstanding problem of these facilities is that the filter screen is easily blocked by the film during the filming of the fry, and the water overflows and the seedlings run away. It is necessary to arrange personnel on duty 24 hours a day to continuously brush off...

AI Technical Summary

Problems solved by technology

[0004] The outstanding problem of these facilities is that the filter screen is easily blocked by the film during the filming of the fry, and the water overflows and the seedlings run away. It is necessary to arrange personnel on duty 24 hours a day to continuously brush off the egg film attached to the filter screen to ensure smooth water flow, which is time-consuming and laborious; The water consumption is large, and it is impossible to artificially control the temperature of the hatching water (even if the hatching device is built indoors, it is impossible to control the indoor temperature because a large amount of hatching water comes from the outside

) and make the hatching of aquatic animals susceptible to weather changes. During the hatching period, when the temperature is low, it is often impossible to hatch, or cause the death of a large number of fry

[0005] Using air flow instead of water flow, designing and manufacturing a water-saving, temperature-controllable aquatic animal hatching device for aquatic animal hatching is of great significance for solving the outstanding problems existing in the existing hatching facilities for aquatic animals, and there is no report at home and abroad
