Description

fish incubator

technical field

The utility model relates to a fishery equipment, in particular to a fish incubator.

Background technique

At present, fish incubators are mainly used in fish hatching scientific research experiments and large-scale production, and mainly consist of three parts, namely: water inlet system, hatch tank and filtration drainage system. During the hatching process, the fish fertilized eggs move up and down in the barrel under the action of the water flow through the water inlet and the water outlet, so that they will not sink to the bottom and be hatched. At present, there are mainly three kinds of hatching barrels used in production. One is to use reinforced concrete pouring, the other is to use clay tanks, and the third is to use tin buckets. However, (1) Due to the limitation of the technical level, the smoothness of the inner wall of the above three types of hatching tanks can not meet the ideal requirements, and the hatching process of fish fertilized eggs and the newly hatched seedlings need to roll continuously under the action of water flow, In this way, the fertilized eggs of fish and the newly hatched seedlings are extremely vulnerable to damage during the movement, resulting in low hatching rate and emergence rate; Inconvenient; (3) The water inlet system generally uses galvanized pipes, which are easily corroded. After the rust spots fall off, they enter the hatching tank with the water flow, pollute the water body, and cause harm to fish fertilized eggs and seedlings. The water inlet valve is generally located in the hatching tank Once the water is cut off, it is very easy to cause the fertilized eggs and seedlings to flow back into the water inlet pipe to cause loss or confusion; (4) There is no slow-flow device at the outlet of the water inlet or the slow-flow device is not set properly, which will cause running water in the bucket Dead angle; (5) Drainage generally adopts the bucket mouth overflow type, which is not easy to collect fry and keep the hatching workshop ground dry; (6) The existing hatching system is not equipped with a drain valve, which is not convenient for cleaning and draining. This is extremely unsuitable for the development of modern scientific research and factory hatching production, and there is an urgent need for a hatching equipment or hatching system suitable for its application.

In addition, the utility model also has the advantages of convenient material selection, simple structure and manufacturing process, and low cost. The glass balls provided in the barrel of the utility model can not only play the role of slow flow but also promote the water flow to flow upwards around the barrel wall to form an inward buffer, reducing the chance of fertilized eggs and fish fry rubbing against the hatching barrel wall, At the same time, the glass ball is a check valve, which can effectively ensure that the fertilized eggs and seedlings will not be lost once the water is cut off. The water inlet system in the utility model adopts PVC pipe fittings, which are corrosion-resistant and will not pollute the water body. The water inlet control valve is set at the same height as the drainage hole of the hatching bucket, and the hatching bucket and the water inlet pipe are connected to form a "U"-shaped connector structure. , Further reducing the possibility of loss and mixing of fertilized eggs and seedling return in the hatching bucket caused by water cut-off. The utility model adopts a movable filter net, and the hatching waste water is discharged from the water outlet, and the water outlet can be used for draining water and collecting fry without causing the ground of the hatching workshop to be wet. The movable filter screen can be selected according to the different needs of different hatching varieties or different periods of hatching, which is easy to operate. In addition, a blowdown valve is set to facilitate cleaning and blowdown.
