Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, the present application provides an in-tank shrimp incubator, which is disposed within an aquarium 1, particularly a seawater aquarium; the shrimp incubator of fairy shrimp in the jar includes: a box body 5, an upper cover 4 and a filter screen 7, wherein,
the box body 5 is a hollow box body with the top and the bottom opened; a shrimp outlet is formed in one side of the middle of the box body 5, and a window door 6 capable of being opened and closed is arranged at the shrimp outlet; the upper cover 4 is hinged on the top opening of the box body 5; the filter screen 7 is fixed at the bottom opening of the box body 5.
When the brine shrimps are incubated, after the upper cover 4 is turned over and opened, the brine shrimps are put into the box body 5, the box body 5 is placed into the aquarium 1, a water source in the aquarium 1 is led into the box body 5 of the incubator, the water source in the box body 5 is continuously turned over and kept in an oxygen-enriched state, so that the brine shrimps are incubated, and input water flows back into the aquarium 1 through the filter screen 7 at the bottom; after the incubation is finished, the window and the door 6 are opened, the shrimps can swim out of the box body 5 from the shrimp outlet and enter the aquarium 1 due to phototaxis of the shrimps, and thus the shrimps can be guided into the aquarium 1 without manual operation.
Furthermore, the box body 5, the window and door 6 and the filter screen 7 are made of black materials. The box body 5 and the window and door 6 are made of acrylic; the filter screen 7 is a 200-mesh filter screen. The box body 5 is a rectangular box body or a cylindrical box body.
Further, referring to fig. 2, one side of the upper cover 4 is hinged with the box body 5; a first locking block 41 is arranged on one side, opposite to the hinge point, of the upper cover 4 in a sliding manner; the box body 5 is provided with a first lock slot 42 corresponding to the first lock block 41; after the first locking block 41 slides into the first locking groove 42 relative to the upper cover 4, the upper cover 4 is locked on the box body 5; after the first locking piece 41 slides out of the first locking groove 42, the upper cover 4 is unlocked.
Further, a first sealing strip is arranged at the edge of the upper cover 4, and after the upper cover 4 is pressed down, the top opening of the box body 5 is sealed by the first sealing strip; the border of window and door 6 is provided with the second sealing strip, and after window and door 6 closed, the shrimp mouth will be gone out to the second sealing strip sealed.
Furthermore, one side of the window door 6 is hinged with the box body 5; a second locking block 62 is arranged on one side of the window door 6 opposite to the hinge point in a sliding manner; the box body 5 is provided with a second locking groove 61 corresponding to the second locking block 62; after the second locking block 62 slides into the second locking groove 61 relative to the box body 5, the window and door 6 is locked on the box body 5; after the second locking piece 62 slides out of the second locking groove 61, the window and door 6 is unlocked.

The water pump 3 inputs the water source in the aquarium 1 into the tank body 5 through the water inlet pipeline 2, so that the seawater is turned over, and the brine shrimp eggs are not sunk at the bottom, thereby being convenient for fully absorbing oxygen and successfully hatching.
Furthermore, supporting legs are respectively arranged at the bottom corners of the box body 5; when the shrimp incubator works in the tank, the supporting legs 8 are pressed at the bottom of the aquarium 1 and used for supporting the tank body 5, so that a certain space is reserved between the filter screen 7 and the bottom of the aquarium 1, and water conveniently input into the tank body 5 flows out of the filter screen 7.
Based on the same invention concept, the application also provides a method for hatching the brine shrimp, which is implemented by the in-cylinder brine shrimp incubator and comprises the following steps:
s1: the upper cover 4 is turned over and opened;
s2: putting shrimp eggs into the box body 5 from the top and then locking the upper cover 4;
s3: placing the box body 5 into the aquarium 1;
s4: the inlet end of the water inlet pipeline 2 is communicated with a water source inside the aquarium 1;
s5: starting the water pump 3, and filling water into the box body 5;
s6: after 24 hours of water filling, the water pump 3 stops working, the window and the door 6 are opened, and the brine shrimps swim out of the box body 5;
s7: the window door 6 is closed, the shrimp incubator in the tank is taken out of the aquarium 1, and then the shells and dead eggs of the shrimps in the tank 5 are removed.
The shrimp incubator in the jar that provides through adopting this application carries out the hatching of fairy shrimp, has following advantage:
adopt water pump 3 and entering pipeline 2 to the mode of box 5 slow flow water intaking, guarantee that oxygen is abundant in the incubator, avoid the shrimp ovum oxygen deficiency to die, cause the water body to foul.
The bottom of the box body 5 adopts a 200-mesh filter screen 7, so that all shrimp eggs cannot enter the aquarium 1, and the fish is prevented from eating the shrimp eggs with shells to cause diseases or death.
The incubation of the brine shrimp is carried out, the incubator is placed in the aquarium 1, the water source and the aquarium 1 are at the same temperature, the temperature of the general aquarium 1 can be controlled to be 20-30 ℃, the temperature can just ensure the good incubation rate of the brine shrimp, and the temperature condition for incubating the brine shrimp is ensured.
The hatched small brine shrimps swim out through the window and directly serve as the feed for the fishes and the shrimps, and the small brine shrimps which cannot be eaten at that time can also live in the aquarium 1, so that the phenomenon that the water quality is deteriorated because other feeds cannot be eaten and fall into the water is avoided.
The above-mentioned embodiments, objects, technical solutions and advantages of the present invention are further described in detail, it should be understood that the above-mentioned embodiments are only illustrative of the present invention and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
