AI Technical Summary
In existing fish fry hatching devices, the fish fry move with the water flow, resulting in uneven density. In some areas, the density is too high, and oxygen is consumed too quickly, which cannot meet the needs of increasing the hatching rate.
The modular design divides the pool area by a combination of long and short partitions, uses an air pump to inject oxygen and a heater to regulate the temperature, and utilizes paddles and bevel gears to rotate the water flow, creating a suitable incubation environment.
This ensured the uniform distribution of fish fry in the pond, guaranteed appropriate density and oxygen supply, and improved the hatching rate and hatching effect.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture technology, specifically a modular fish fry hatching tank. Background Technology
[0002] Fish fry hatching is a crucial step in fish fry production, and one of the most important parameters in hatching is the hatching rate. To improve the hatching rate, it is necessary to use flowing water for hatching the eggs and to ensure the oxygen content of the water. The oxygen content in the water changes with the density of fish fry, necessitating a modular fish fry hatching tank.
[0003] The existing patent, CN210017482U, entitled "A Fish Fry Hatching Device," relates to the field of fish farming technology, specifically a fish fry hatching device. The main technical solution is as follows: A fish fry hatching device includes a water tank and hatching containers; one end of the water tank has a water inlet, and the other end has a water outlet; the hatching containers are placed in the water tank; there are at least two hatching containers; the at least two hatching containers are distributed sequentially along the water tank; the bottom of the hatching containers has a water inlet hole for water flow; a mesh screen is provided at the bottom of the hatching containers; a water outlet hole is provided on one side of the hatching containers; water flowing into the water tank from the water inlet hole enters the hatching containers through the water inlet hole at the bottom of the hatching containers, then flows out through the mesh screen and exits through the water outlet hole, then enters the water inlet hole of the next hatching container, until it is discharged from the water outlet hole. This utility model can ensure uniform water flow across multiple hatching containers, improving the hatching rate.
[0004] The water flowing into the tank from the inlet enters the hatching container through the inlet hole at the bottom of the hatching container, then flows out through the outlet hole after passing through the mesh screen, and then enters the inlet hole of the next hatching container until it is discharged from the outlet. However, the movement of the fish fry with the water flow can easily lead to excessive fish fry density in some areas, excessive consumption of oxygen in the water, and cannot meet people's needs. In view of the above situation, technical innovation is carried out on the basis of the existing fish fry hatching tank. Utility Model Content

The locking strips on both sides of the long partition and the short partition can be inserted into the side rails, locking blocks and connecting blocks.
[0008] Furthermore, a hook is installed above the short partition, and an adjustment component is installed on one side of the hook. A certain number of adjustment components can be hung on appropriate positions on the long and short partitions by the hook.
[0009] Furthermore, the regulating component includes an air pump and an air pipe, with the air pipe installed below the air pump, through which the air pump injects oxygen into the water.

[0011] Furthermore, a partition net is installed on the upper part of the base, and a paddle is provided below the partition net. The partition net separates the paddle from the water pool above, preventing fish fry from entering the space where the paddle is located.
[0012] Furthermore, a bevel gear set is installed below the blade, and the bevel gear set is welded to the blade. The blade drives the water above to rotate and flow slowly, ensuring a suitable water flow environment.
[0013] Furthermore, a linkage rod is installed inside the lower part of the bevel gear set, and a motor is installed at one end of the linkage rod. The motor drives the two bevel gear sets to rotate through the linkage rod, and the two blades are driven to rotate.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the clips on both sides of the long partition and the short partition can be inserted into the side rails, clips and connecting blocks. The water tank can be divided into areas of different sizes by connecting and combining the long partition and the short partition, so as to ensure that the fish fry in the water tank are distributed at a suitable density. The partition net separates the paddles from the water tank above. The motor drives the two bevel gear sets to rotate through the linkage rod. The two paddles are driven to rotate. The paddles drive the water above to rotate slowly and flow, so as to ensure a suitable water flow environment. A certain number of adjustment components are hung on the long partition and the short partition at appropriate positions through the hook. The air pump injects oxygen into the water through the air pipe. The heater heats the water to a suitable temperature through the heating rod, so as to create a suitable incubation environment.
[0015] 1. The clips on both sides of the long partition and the short partition of this utility model can be inserted into the side rails, clips and connecting blocks. The connecting blocks serve as movable connection points in the pool, which facilitates the adjustment of the position of each enclosure module. The pool can be divided into areas of different sizes by connecting and combining the long partition and the short partition, preventing the fish fry from concentrating in one area of the pool after hatching, and ensuring that the fish fry in the pool are distributed at a suitable density.
