Cultivating seedlings in aquatic nursery ponds is an important link and key technology in aquaculture. Currently, when collecting seedlings in aquatic nursery ponds, most of the fishing operations are done manually with handheld nets.

[0003] This method can catch a small number of seedlings at a time and is easy to cause damage to the seedlings. In addition, the seedlings are hatched in large-scale nursery facilities, and it is troublesome to catch the surviving seedlings, which may even cause damage to the seedlings. In large-scale hatching facilities, the probability of group infection is high, and it is difficult to replace the living water area of ​​the seedlings, which increases the cost of aquaculture. Summary of the invention

[0008] By adopting the above technical scheme, when using, firstly power on the device, place the first water inlet pipe in the water tank, open one end of the two-position three-way solenoid valve and close the other end, close the first control valve and the second control valve, let the water pump work to draw a proper amount of water from the first water outlet pipe into the nursery pond, then place the fish eggs to be hatched in the nursery pond for hatching, and when the fish eggs are hatched into seedlings, add a proper amount of water into the collection box, keep the second control valve closed, open the first control valve and put it into the nursery pond. The seedlings will flow into the collection box from the second water diversion pipe and the second water diversion pipe along the water body. At the same time, one end of the two-position three-way solenoid valve is closed and the other end is opened. The water pump draws the water in the collection box into the seedling pool through the second water inlet pipe to control the water level in the collection box. When collecting the seedlings, the lower end of the guide sleeve is downwardly set under the action of water pressure and water flow, and its lower end is flushed open by the flow of water, which avoids damage to the seedlings and can control the flow rate. When there are a large number of seedlings in the collection box, just take out an appropriate amount of seedlings.

A wedge-shaped guide block 13 detachably connected to the collecting box 12 is arranged at the bottom of the inner wall of the collecting box 12 and tilted downward from front to back. Gaps are left between the front and rear ends of the guide block 13 and the front and rear ends of the inner wall of the collecting box 12. A filter screen 14 cooperating with the guide block 13 is arranged on the edge of the front end of the guide block 13 in the collecting box 12. A first water diversion pipe 16 extending from the front end of the outer wall of the guide block 13 is arranged at the front end. One end of the first water diversion pipe 16 extending from the collecting box 12 is connected to a first control valve 17. The front end of the first control valve 17 is connected to a first three-way pipe 18.

[0037] A second water diversion pipe 19 is connected between the bottom of the inner wall of the seedling raising pool 11 and one end of the first three-way pipe 18. The front end of the second water diversion pipe 19 is connected to a conical, elastic and deformable guide sleeve 2. A spoiler frame 21 is arranged above the guide sleeve 2 at the bottom of the inner wall of the seedling raising pool 11. A water pump 22 is installed at the lower end of one side of the outer wall of the support frame 1. A two-position three-way solenoid valve 23 connected to the water inlet of the water pump 22 is installed. A first water inlet pipe 24 is connected to one end of the two-position three-way solenoid valve 23. A second water inlet pipe 25 extending to the front end of the bottom of the inner wall of the collecting box 12 is connected to the other end of the two-position three-way solenoid valve 23. A filter 26 is arranged at one end of the second water inlet pipe 25 away from the water pump 22. A second three-way pipe 27 connected to the water outlet of the water pump 22 is installed. One end of the second three-way pipe 27 is connected to the first water outlet pipe 28 extending into the seedling raising pool 11.

[0038] The inner wall of the nursery pool 11 is provided with a water spray assembly 29 for controlling the rotation of the water flow and connected to the first water outlet pipe 28. The water spray assembly 29 includes a water pipe 3 arranged in an annular shape, a plurality of flow pipes 31 arranged at equal intervals at the lower end of the water pipe 3 and connected thereto, and a plurality of water spray heads 32 arranged at an inclined state on the outer wall of the flow pipe 31. The angle between each water spray head 32 and the axis position of the corresponding flow pipe 31 is 45°. The other end of the first three-way pipe 18 is provided with a second control valve 33 connected thereto. The other end of the second three-way pipe 27 is connected to the second control valve 33. A second water outlet pipe 34 is connected to the seedling pool 11, and an overflow pipe 35 connected to the seedling pool 11 and extending to the upper end of the outer wall of the guide block 13 is arranged upward from the lower end of one side of the outer wall of the seedling pool 11. The height of the overflow pipe 35 is lower than the height of the seedling pool 11. A partition net 36 connected to the overflow pipe 35 is arranged at one end of the seedling pool 11. The overflow pipe 35 and the end of the first water diversion pipe 16 close to the guide block 13 both pass through the rear end of the filter net 14. A control panel 37 is arranged above one side of the outer wall of the seedling pool 11, and the water pump 22 and the two-position three-way solenoid valve 23 are electrically connected to the control panel 37.

[0039] Usage: When in use, firstly energize the device, place the first water inlet pipe 24 in the water tank, open one end of the two-position three-way solenoid valve 23 and close the other end, close the first control valve 17, open the second control valve 33, and let the water pump 22 work to draw an appropriate amount of water from the first water outlet pipe 28 to the second three-way pipe 27 and then divide it into two water paths. One water path passes through the first water outlet pipe 28 and the water spray assembly 29, and the water flows from the water guide pipe 3 to the guide pipe 31 and is sprayed from the water spray head 32. The water in the other water path flows into the nursery pool 11 on the support frame 1 through the second water outlet pipe 34, the first three-way pipe 18, the second water guide pipe 19 and the guide sleeve 2, and then the fish eggs to be hatched are placed in the nursery pool 11 for hatching. During the hatching process, the water pump 22 draws water and sprays it from the water spray assembly 29 to make the water in the nursery pool 11 flow.

[0040] When the water level in the nursery pond 11 is higher than the overflow pipe 35, the excess water will automatically flow into the collecting box 12, and the partition net 36 can prevent the fish eggs from entering the overflow pipe 35. Then, both ends of the two-position three-way solenoid valve 23 are opened, and the second water inlet pipe 25 allows the water to be purified through the filter 26 and then enter the nursery pond 11 from two waterways respectively, thereby realizing the recycling of the water body and improving the dissolved oxygen content of the water body. In this process, the opening of the guide sleeve 2 is flushed open by the water flow, and the water body enters the nursery box, while the water flow with impact force is blocked by the spoiler frame 21, thereby reducing the impact on the fish eggs or seedlings. When water is not entering from the guide sleeve 2, the first control valve 17 and the second control valve 33 are closed. When the water pressure is balanced, the open end of the guide sleeve 2 automatically shrinks and returns to the initial state to prevent the fish eggs from entering the second water diversion pipe 19.

[0041] After the fish eggs are hatched into seedlings, an appropriate amount of water is added to the collecting box 12, and the second control valve 33 is kept closed, and the first control valve 17 is opened. The seedlings in the nursery pool 11 will flow into the collecting box 12 along the water body from the second water diversion pipe 19 and the first water diversion pipe 16 and flow backward along the guide block 13. At the same time, one end of the two-position three-way solenoid valve 23 is closed and the other end is opened. The water pump 22 draws the water in the collecting box 12 into the nursery pool 11 through the first water outlet pipe 28 through the second water inlet pipe 25 to control the water level in the collecting box 12. Under the blocking effect of the filter screen 14, the seedlings and water impurities will not flow to the front end of the collecting box 12. When collecting the seedlings, the lower end opening of the guide sleeve 2 is set downward under the action of the water pressure and the water flow, and its lower end is flushed open by the flow of the water flow, so as to avoid damaging the seedlings while controlling the flow rate. When the number of seedlings in the collecting box 12 is large, the drain valve 15 is opened to discharge an appropriate amount of seedlings.

[0042] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
