Two mounting slots at the top of the slide rail 2 each have a fixed post 4 fixedly installed. Rotating blocks 5 are rotatably connected to the surfaces of the two fixed posts 4. The sides of the two rotating blocks 5 are fixedly connected by pull plates 10. The bottom of the rotating blocks 5 is inserted into a slot at the top of the hatching tray 3. A water receiving trough 6 is fixedly installed inside the mounting frame 1. An overflow port 7 is provided on the side of the hatching tray 3. A partition net 8 is inserted into a rectangular slot at the top of the hatching tray 3, and a handle is fixedly installed on the top of the partition net 8. A screen 9 is fixedly installed inside the hatching tray 3 by bolts. Two slide rails 2 are fixedly installed inside the mounting frame 1 in the same plane, and there are three sets of slide rails 2. Sliding connections are made inside the two slide rails 2. The hatching tray 3 is slidably connected to the interior of the three sets of slide rails 2. The top of the slide rail 2 has two identical mounting slots, and a fixing column 4 is fixedly installed inside the mounting slot. A rotating block 5 is rotatably connected to the surface of the fixing column 4, so that the rotating block 5 can be inserted into the slot opened at the top of the hatching tray 3. The two rotating blocks 5 can be connected by a pull plate 10 on their sides. A water receiving trough 6 is welded inside the mounting frame 1 and is installed near the bottom of the hatching tray 3. The side of the hatching tray 3 has multiple overflow ports 7, which can overflow excess water when water is added. A rectangular groove is opened at the top of the hatching tray 3, which facilitates the insertion of a partition net 8 inside the rectangular groove, so that the partition net 8 can isolate the fish eggs and prevent them from overflowing. The screen 9 can be installed inside the hatching tray 3 by bolts, which facilitates water flow and prevents the fish eggs from leaking out.
[0024] like Figures 3 to 5As shown, a connecting hose 11 is fixedly installed on the side of the incubation tray 3, and a check valve is fixedly installed on the surface of the connecting hose 11. The other end of the connecting hose 11 is fixedly installed on the top of the main water pipe 12 via a tee. The other end of the main water pipe 12 is fixedly installed on the top of the first diversion box 13. A first connecting pipe 14 is fixedly installed on the bottom of the first diversion box 13. The bottom of the first connecting pipe 14 is fixedly installed on the outlet of the main water pump 15 via a flange. The other end of the main water pump 15 is fixedly installed on the top of the water storage tank 16 via a flange. An auxiliary water pump 17 is fixedly installed on the top of the water storage tank 16. The auxiliary water pump 17 is a variable frequency water pump. A second connecting pipe 18 is fixedly installed on the other end of the auxiliary water pump 17 via a flange. A second diversion box 19 is fixedly installed on the top of the second connecting pipe 18. An auxiliary water pipe 20 is fixedly installed on the top of the second diversion box 19. The other end of the auxiliary water pipe 20 is fixedly installed on the top of the second diversion box 19 via a tee. The hatching trays 3 are connected to the connecting hoses 11. There are three hatching trays 3, and the connecting hoses 11 are fixedly installed on the sides of each of the three hatching trays 3. Check valves are installed on the surface of each of the three connecting hoses 11 to prevent siphoning of water when the pump stops. The other end of the connecting hose 11 is connected to the main water pipe 12 through a T-junction. The other end of the main water pipe 12 is fixedly installed on the top of the first diversion box 13. The bottom of the first diversion box 13 is installed on the top of the first connecting pipe 14. The first connecting pipe 14 is connected to the main water pump 15, so that the main water pump 15 can draw water from the water storage tank 16. The drawn water can be transported to the three connecting hoses 11 through the first diversion box 13. The auxiliary water pump 17 installed on the top of the water storage tank 16 can adjust the pumping speed, and thus the speed of the auxiliary water pump 17 can be adjusted according to the needs of fish egg hatching to facilitate the use of the device.
[0025] like Figures 4 to 5 As shown, a drain pipe 21 is fixedly installed at the bottom of the water receiving tank 6, and the other end of the drain pipe 21 is fixedly installed on the surface of the guide pipe 22. The bottom of the guide pipe 22 is fixedly installed on the top of the collection tank 23. A filter device is installed inside the collection tank 23. A return pump 24 is fixedly installed on the side of the collection tank 23. A return pipe 25 is fixedly installed at the other end of the return pump 24. The other end of the return pipe 25 is fixedly installed on the side of the water storage tank 16. The drain pipe 21 fixedly installed at the bottom of the water receiving tank 6 can collect the overflowing water into the collection tank 23 through the guide pipe 22. A filter device is installed in the collection tank 23 to filter the incoming water for water recycling. The return pump 24 fixedly installed on the side of the collection tank 23 can transport the water in the collection tank 23 into the water storage tank 16 through the return pipe 25.
[0026] Working principle: During operation, when incubating rainbow trout eggs, the eggs are placed inside the incubation tray 3, which is then mounted onto the mounting frame 1 via the slide rail 2. To fix the position of the incubation tray 3, the angle of the rotating block 5 can be adjusted. When the incubation tray 3 slides within the slide rail 2, it pushes the rotating block 5, thus fixing the position of the incubation tray 3. During egg incubation, the main water pump 15, installed on top of the water storage tank 16, pumps water from the tank through the first connecting pipe 14 to the first distribution box 13. This facilitates water distribution through the first distribution box 13 and the main water pipe 12 to the three connecting hoses 11, allowing water to enter the three incubation trays 3. Internally, when regulating the water flow, the auxiliary water pump 17 on the water storage tank 16 can adjust the pumping speed so that water can be delivered to the inside of the connecting hose 11 through the second connecting pipe 18, the second diversion box 19, the auxiliary water pipe 20 and the tee, thereby regulating the water flow rate. When recycling the water, the drain pipe 21 fixedly installed at the bottom of the water receiving tank 6 can collect the overflowing water into the collection tank 23 through the guide pipe 22. A filter device is installed in the collection tank 23 to filter the incoming water for recycling. A return pump 24 is fixedly installed on the side of the collection tank 23 so that the return pump 24 can deliver the water in the collection tank 23 to the inside of the water storage tank 16 through the return pipe 25.
