[0023] Beneficial effects:

[0024] (1) By setting up an ecosystem and making reasonable vertical planning, poultry, fish and plants are cultivated separately.

This can not only reduce the waste of space, but also realize diversified breeding and improve the risk resistance of actual production.

[0025] (2) By setting up a filtering component and utilizing the arc-shaped turbulence effect of the arc plate, fish feces are accumulated inside the arc plate when liquid water circulates. At the same time, by utilizing the combination of fixed strips, pads and connecting blocks, a 4:6 water and 2:8 sand effect can be formed. By utilizing the vortex groove and separation groove, fish feces can be concentrated and accumulated on one side inside the arc plate for easy recycling.

[0026] (3) By setting up a recovery unit and utilizing a combination of a suction hood, a spring tube, and a solid barrel, the fish feces can be recovered inside the filter cartridge by utilizing negative pressure. Then, by connecting the filter cartridge and the solid barrel, the recovered fish feces can be discharged into the cultivation tray through the discharge end of the solid barrel, thereby fertilizing the plants.

[0027] (4) By setting up a flow-uniform unit, using a fixed frame and a sliding frame to receive the returned liquid water, and using the flow-uniform holes to evenly distribute and decelerate the liquid water, it can not only improve the oxygenation effect, but also reduce the water flow rate to avoid affecting the activities of fish. At the same time, by using the sliding of the sliding frame, it can not only increase the load-bearing capacity, but also realize the flow diversion through the flow-uniform holes set on the side.

[0028] (5) By setting up a speed control module, when the slide frame descends to increase the water carrying capacity, the brake plate and the abutment plate on one side are abutted by the abutment block, so that the brake plates on both sides are close to each other to increase the clamping degree of the brake disc, so that the rotation speed of the blade decreases as the water flow increases, thereby maintaining the water flow speed and avoiding affecting the fish.

At the same time, the circulation pipe 5 is used to circulate the liquid water in the water tank 3. On the one hand, it is used to oxygenate the liquid water to facilitate the growth of fish. On the other hand, the fish droppings in the water can be separated and filtered so that the liquid water can be used continuously. At the same time, the separated fish droppings can be used for fertilizing plants.

[0041] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 1 , Attachment Figure 2 ;

[0042] The filter assembly 6 includes an arc plate 61, the interior of the arc plate 61 is arc-shaped to provide a convex point, so as to facilitate the accumulation and separation of fish feces. The interior of the arc plate 61 is connected to the interior of the circulation pipe 5, and a fixed strip 63 is fixedly connected to the interior of the arc plate 61.

The vortex groove 69 cooperates with the separation groove 67 to form a vortex in the diverted water, so as to separate the fish feces in the diverted water, thereby causing the fish feces to accumulate in a concentrated manner.

[0043] In this embodiment, when the liquid water flows and circulates inside the arc plate 61, the fish feces it carries will accumulate in large quantities at the inner convex part of the arc plate 61. At the same time, the liquid water is diverted by the fixed strip 63, and a part of it is diverted through the branch pipe 65. During the diversion, a vortex is formed by the vortex groove 69, so that the fish feces contained in the water are separated and thrown to the inner convex part of the arc plate 61 through the action of the separation groove 67 for centralized accumulation, so that the fish feces in the liquid water are filtered, so that the liquid water can be recycled.

[0044] Embodiment 3: Based on Embodiment 2, refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 ;

[0045] The arc plate 61 is provided with a recovery unit 62, which includes a suction cover 621. One side of the suction cover 621 is provided with an opening facing the inner convex part of the arc plate 61 for sucking and recovering fish feces. The outer surface of the suction cover 621 is movably connected to the inside of the arc plate 61. The inside of the suction cover 621 is penetrated and connected with a spring tube 622.

The outer surface of the lifting rod 623 is fixedly connected with a linear motor 624. The linear motor 624 is electrically connected to the external control circuit, and a waterproof measure is provided on the outside. The outer surface of the linear motor 624 is slidably connected with Slide rail 625, the shape of slide rail 625 is similar to arc plate 61, and guides the movement of suction cover 621. The outer surface of slide rail 625 is fixedly connected to the upper part of the inner part of arc plate 61. A solid barrel 626 is arranged on the outside of spring tube 622. Both sides of the inner part of solid barrel 626 are penetrated and connected with connecting pipes 627. One end of the connecting pipe 627 on the other side is connected with an external negative pressure device. One end of the connecting pipe 627 on one side is connected with one end of spring tube 622. The other end of the connecting pipe 627 on one side is penetrated and connected with a filter cartridge 628. The filter cartridge 628 is hollow as a whole to facilitate the circulation of air, and is a combination of a cylinder and a hopper with solid barrel 626. Electromagnetic valves are arranged at the discharge ends of the two hoppers to facilitate the collection of fish feces and discharge the fish feces into the cultivation tray 4. The outer surface of filter cartridge 628 is fixedly connected to the inner part of solid barrel 626, and one end of the connecting pipe 627 on the other side is arranged above the cultivation tray 4.

[0046] In this embodiment, when it is necessary to recycle the fish feces inside the arc plate 61, the water level of the circulating water is first lowered to below the pad 64, and the water circulates through the branch pipe 65. Then the linear motor 624 moves along the slide rail 625, so that the lifting rod 623 drives the suction cover 621 to follow the movement, and the suction cover 621 is lifted and lowered to get close to the fish feces at different positions. At the same time, the external negative pressure equipment absorbs the fish feces under negative pressure through the solid barrel 626, the connecting pipes 627 on both sides, the filter cartridge 628, the spring tube 622 and the suction cover 621, and the fish feces are concentrated inside the filter cartridge 628. After the collection is completed, the suction cover 621 is reset, and the negative pressure equipment stops working. Then the solenoid valves on the discharge end of the filter cartridge 628 and the solid barrel 626 are opened, so that the fish feces are discharged into the cultivation tray 4 to fertilize the plants.

[0047] Embodiment 4: Based on Embodiment 3, refer to the attached Figure 1 , Attachment Figure 5 ;

[0048] A flow-uniform unit 66 is arranged outside the branch pipe 65, and the flow-uniform unit 66 includes a fixed frame 661, the interior of the fixed frame 661 is connected to one end of the circulation pipe 5, the body of the fixed frame 661 is embedded with a sliding frame 662, the outer surface of the sliding frame 662 is connected to the inside of the water tank 3, and both sides of the sliding frame 662 body are provided with through flow-uniform holes 663, and the flow-uniform holes 663 are respectively arranged on the side and below the sliding frame 662, and in normal use, the side flow-uniform holes 663 are shielded by the fixed frame 661, and a reset rod 664 is arranged outside the fixed frame 661, and the reset rod 664 is It is made of existing spring rods to facilitate the resetting of the sliding frame 662. Both ends of the resetting rod 664 are fixedly connected with fixed plates 665.

The body of the sliding frame 662 is rotatably connected with a rotating rod 666. The connection between the rotating rod 666 and the sliding frame 662 is provided with a rotating seal and a rotating damping measure, which can reduce the flow rate of the circulating water to avoid affecting the growth of fish. The outer surface of the rotating rod 666 is fixedly connected with a blade 668, and the outer surface of the blade 668 is rotatably connected to the inside of the sliding frame 662.

[0049] In this embodiment, after the circulating water flows back, it falls into the interior of the sliding frame 662 through the fixed frame 661. When the circulating water falls, it contacts the blade 668, causing the rotating rod 666 to rotate, and the water speed is reduced by the rotation damping measures. At the same time, the circulating water is diverted by the flow-balancing hole 663 below to further reduce the flow rate. At the same time, when the circulating water flowing back is more, the load-bearing capacity of the sliding frame 662 increases, thereby descending to increase the capacity, and at the same time stretching the output end of the reset rod 664 to facilitate reset. When the water volume increases to a certain extent, the side flow-balancing hole 663 can achieve further diversion and speed reduction.

[0050] Embodiment 5: Based on Embodiment 4, refer to the attached Figure 5 , Attachment Figure 6 ;

[0051] A speed regulating module 667 is arranged on the outside of the rotating rod 666, and the speed regulating module 667 includes a brake disc 6671, the body of the brake disc 6671 is fixedly connected to the outer surface of the rotating rod 666, and brake plates 6672 are movably connected to both sides of the outer surface of the brake disc 6671, and the brake plates 6672 and the brake disc 6671 are made of pressure-resistant, wear-resistant and corrosion-resistant materials, and groove plates 6673 are movably connected to both sides of the outer surface of the brake plate 6672, and the outer surfaces of the groove plates 6673 on both sides are fixedly connected to the outer surface of the slide frame 662, and two sliders 6674 are slidably connected inside the groove plate 6673, and the slider 6674 is in the shape of an isosceles trapezoid to improve the stability of the connection between the brake plate 6672 and the groove plate 6673, and the outer surfaces of the two sliders 6674 are respectively fixedly connected to the outer surfaces of the brake plates 6672 on both sides, and the outer surface of the brake plate 6672 on one side is movably connected to a stop block 6675, and the stop block 6676 is movably connected to the outer surface of the stop block 6676. The outer surface of 675 is fixedly connected with a fixing rod 6676, one end of which is fixedly connected to the output end of the reset rod 664, the outer surface of the stop block 6675 is fixedly connected with a stop plate 6677, the surfaces of the stop block 6675, the stop plate 6677 and one side brake plate 6672 are all provided with chamfered surfaces, so that the stop plate 6677 and one side brake plate 6672 can move horizontally through oblique abutment, the outer surface of the stop plate 6677 is fixedly connected with a connecting rod 6678, one end of the connecting rod 6678 is slidably connected with the body of one side brake plate 6672, one end of the connecting rod 6678 is fixedly connected to the outer surface of the other side brake plate 6672, the outer surface of the connecting rod 6678 is sleeved with a compression spring 6679, the compression spring 6679 can facilitate the resetting of the brake plate 6672, and the two ends of the compression spring 6679 are respectively fixedly connected to the outer surface of one side brake plate 6672 and the outer surface of the stop plate 6677.

[0052] In this embodiment, when the slide frame 662 drives the output end of the reset rod 664 to descend, the stop block 6675 follows the decline through the fixed rod 6676, and through the contact with the stop plate 6677 and the brake plate 6672 on one side, the two move synchronously, and the brake plate 6672 on one side approaches the contact brake disc 6671, reducing the rotation speed of the rotating rod 666 through friction. At the same time, the brake plate 6672 on the other side synchronously approaches the contact brake disc 6671 through the action of the connecting rod 6678. At the same time, the movement of the stop plate 6677 stretches the compression spring 6679 to facilitate the resetting of the brake plate 6672. The increase in water volume causes the descent value of the slide frame 662 to increase. The greater the clamping degree of the brake plate 6672 on the brake disc 6671, the lower the rotation speed of the rotating rod 666 is, thereby reducing the flow rate of the circulating water.
