[0002] Aquaculture is a production activity in which humans use water environments to cultivate, breed and harvest aquatic organisms (such as fish, shrimp, crab, shellfish, algae, etc.) through artificial control and management. It is an important part of the global food supply and provides humans with a high-quality source of protein.

[0003] Aquaculture often requires oxygenation operations to speed up the metabolism of aquatic organisms, promote their growth rate, and increase aquaculture output. In high temperature seasons, the respiration of aquatic organisms is enhanced, oxygen consumption increases, and high temperature reduces the dissolved oxygen content in the water.

[0027] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by terms such as “front”, “up”, “down”, “left”, “right”, “vertical” and “horizontal” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The following is combined with Figure 1-10 The present invention is further described.

[0030] In order to solve the problems existing in the background technology, the present application proposes the following technical scheme: it includes a breeding pond 1, a reducing tee 2 is provided in the breeding pond 1, a De110PVC pipe 3 is fixedly connected to the reducing tee 2, a pagoda tee 7 is fixedly installed on one side of the reducing tee 2, a nano aeration tube 8 is fixedly installed on the pagoda tee 7, a De20 elbow 9 is fixedly installed on one end of the pagoda tee 7, a De20PVC pipe 10 is fixedly connected to the end of the De20 elbow 9 away from the pagoda tee 7, a PVC pagoda ball valve 11 is fixedly installed on one end of the De20PVC pipe 10, and a gas supply hose 12 is fixedly connected to the end of the PVC pagoda ball valve 11 away from the De20PVC pipe 10.

[0031] The end of the gas delivery hose 12 away from the PVC pagoda ball valve 11 is connected to the output end of the air pump of the external gas supply equipment (not shown in the figure), and the gas is transported to the nano aeration tube 8 through the De20PVC tube 10 (with an outer diameter of 20mm), the De20 elbow 9 and the pagoda tee 7 (10-20-10mm Y-shaped internal pagoda). The gas passes through the nano gaps in the nano aeration tube 8 to form tiny bubbles inside, thereby improving the solubility of the bubbles and releasing more oxygen in the water, thereby improving the oxygenation effect on the water body. Compared with traditional oxygenation equipment, the nano aeration tube 8 can greatly reduce The loss and consumption of oxygen can achieve the effect of reducing energy consumption. The bubbles rise and are discharged in the reducing tee 2. The bubbles push the water to flow, increase the contact area between water and air, and promote the dissolution of oxygen in the air into the water, thereby further increasing the dissolved oxygen content of the water. At the same time, the flow of water can accelerate the decomposition and transformation of harmful substances in the water, avoid the formation of dead water areas, and help maintain the freshness and stability of water quality. The air intake of the De20PVC pipe 10 can be adjusted through the PVC pagoda ball valve 11 (specification is 20*10mm), so as to adjust the size of the water flow and improve the convenience of using the device.

[0032] It is further explained that a De110PVC pipe 3 is fixedly connected to the reducing tee 2, an eccentric reducing sleeve 4 is fixedly installed on the De110PVC pipe 3, and a De75 elbow 5 is fixedly connected to the eccentric reducing sleeve 4.

[0033] The outer diameters of the upper and lower ends of the reducing tee 2 are 110mm, and the outer diameter of the side port is 20mm. One end of the De110PVC pipe 3 (outer diameter 110mm) is connected to the upper end of the reducing tee 2, and the other end of the De110PVC pipe 3 is connected to the lower end of the eccentric reducing sleeve 4 (outer diameter 110mm and inner diameter 75mm). The upper end of the eccentric reducing sleeve 4 is connected to the De75 elbow 5 (outer diameter 75mm). The tiny bubbles rising in the reducing tee 2 rise in the De110PVC pipe 3 and the eccentric reducing sleeve 4 and are discharged from the De75 elbow 5. The bubbles push the De The water at the 75 elbow 5 flows, increasing the dissolved oxygen effect of the water. When in use, the De75 elbow 5 is exposed to the water by 1-2 cm, causing the water near the De75 elbow 5 to surge, increasing the contact area between the water and the air, and further increasing the dissolved oxygen content in the water. The setting of the eccentric reducer 4 not only connects the De110PVC pipe 3 and the De75 elbow 5 of different diameters, but also avoids the accumulation of bubbles caused by changes in the pipe diameter, ensuring smooth water flow, preventing pipe blockage or reduced water transportation efficiency due to bubble accumulation, and improving the practicability of the device.

[0034] The air delivery hose 12, PVC pagoda ball valve 11, De20PVC pipe 10, De20 elbow 9, pagoda tee 7, nano aeration pipe 8, De110PVC pipe 3, eccentric reducer 4 and De75 elbow 5 form a push water pump with simple structure and low overall cost. An air pump with a gas volume of 120 liters has a power of 90 watts and can drive six groups of push water pumps at the same time. The maximum water flow rate is 7 tons per hour. The traditional electric oxygenation water pump has a power of 100-150 watts per unit with the same flow rate, which significantly reduces energy loss, reduces the cost of aquaculture, increases the economic benefits of aquaculture, and reduces energy waste, which is more in line with the development concept of energy conservation and emission reduction.

[0035] It is further explained that a mesh bushing 6 is fixedly installed on one end of the reducing tee 2 away from the De110PVC pipe 3 .

[0036] The mesh core 6 is provided with filter holes, which can effectively prevent fish from being sucked into the reducing tee 2, thereby preventing fish casualties and reducing the economic benefits of aquaculture, and improving the practicality of the reducing tee 2.

[0037] It is further explained that the outside of the reducing tee 2 is fixedly connected with a PVC fixed pipe 13, and the outside of the De110PVC pipe 3 is fixedly installed with a connecting block 14, which is sleeved on the outside of the De20PVC pipe 10 and the PVC fixed pipe 13.

[0038] Both the PVC fixed pipe 13 and the De20PVC pipe 10 are provided with a "U"-shaped structure, through which the PVC fixed pipe 13 and the De20PVC pipe 10 are hung on the wall of the breeding pond 1, so that the push water pump is fixed in the breeding pond 1. The PVC fixed pipe 13 plays a role in assisting in fixing the reducing tee 2, thereby improving the stability of the push water pump when it is placed. The setting of the connecting block 14 plays an effect of reinforcing the connection between the De20PVC pipe 10, the PVC fixed pipe 13 and the reducing tee 2.

[0039] It is further explained that a support block 15 is arranged below the PVC fixed pipe 13 , a fixed block 16 is movably arranged below the support block 15 , and a slot 17 is provided at the bottom of the fixed block 16 .

[0040] The support block 15 is provided with a groove compatible with the PVC fixed pipe 13 and the De20PVC pipe 10. The "U"-shaped part of the De20PVC pipe 10 and the PVC fixed pipe 13 is placed in the groove of the support block 15 to improve the fixing effect of the PVC fixed pipe 13 and the De20PVC pipe 10. The fixing block 16 is fixedly placed on the breeding pond 1 by clamping the slot 17 on the wall of the breeding pond 1. The fixing block 16 cooperates with the support block 15 and the De20PVC pipe 10 and the PVC fixed pipe 13 to fix the push water pump in the breeding pond 1, thereby improving the stability of the push water pump in the breeding pond 1.

[0041] It is further explained that a mounting groove 18 is provided at the bottom of the support block 15, and two groups of slides 19 are slidably installed in the mounting groove 18. A connecting rod 21 is rotatably installed at the bottom of the two groups of slides 19. The end of the connecting rod 21 away from the slide 19 is rotatably connected to the fixed block 16. A threaded rod 20 is rotatably installed in the mounting groove 18, and the threaded rod 20 is threadedly connected to the slide 19.

[0042] When the threaded rod 20 rotates, the two groups of slides 19 are pushed to move relative to each other. When the two groups of slides 19 are relatively close to each other, the slide 19 pushes the fixed block 16 through the connecting rod 21. Since the fixed block 16 is fixed on the culture pond 1, the support block 15, the De20PVC pipe 10 and the PVC fixed pipe 13 move upward, driving the push water pump to be lifted upward in the culture pond 1; when the two groups of slides 19 are relatively far away from each other, the slide 19 pulls the fixed block 16 through the connecting rod 21, and the support block 15, the De20PVC pipe 10 and the PVC fixed pipe 13 move downward, driving the push water pump to move downward in the culture pond 1, so that the height of the push water pump in the culture pond 1 can be adjusted by rotating the threaded rod 20, so that the De75 elbow 5 is always kept 1-2 cm above the water surface, ensuring that the push water pump is in the best working state according to the water depth in the culture pond 1, which is conducive to reducing energy loss.

[0043] It is further explained that a turntable 24 is rotatably mounted on the outside of the support block 15 , and the turntable 24 is coaxially fixedly connected to the threaded rod 20 .

[0044] The threaded rod 20 can be driven to rotate by the turntable 24, thereby improving the convenience of adjusting the height of the water pump.

[0045] It is further explained that a limiting groove 22 is provided on the side wall of the installation groove 18 , and a limiting block 23 is slidably installed in the limiting groove 22 , and the limiting block 23 is fixedly connected to the side surface of the slide seat 19 .

[0046] The limit block 23 cooperates with the limit groove 22 to guide and limit the movement of the slide 19, preventing the slide 19 from flipping over when the threaded rod 20 rotates, improving the stability of the slide 19 during movement, and thus improving the smoothness and stability of the water pump height adjustment.

[0047] It is further explained that a plurality of groups of limiting holes 25 are formed on the rotating disk 24 , and inserting rods 27 are inserted into the limiting holes 25 . A slot 26 is formed at one end of the supporting block 15 , and the slot 26 is matched with the inserting rod 27 .

[0048] After adjusting the water push pump to a suitable height, insert the rod 27 into the limiting hole 25 and the slot 26 in sequence. The rod 27 cooperates with the limiting hole 25 and the slot 26 to limit the rotation of the turntable 24 to prevent the turntable 24 from accidentally rotating due to external force, so that the height of the water push pump in the breeding pond 1 is stable, ensuring the oxygenation and water flow promotion effects of the water push pump.

[0049] It is further explained that a fixing bolt 28 is threadedly connected to one side of the fixing block 16, one end of the fixing bolt 28 is fixedly connected to a turning handle 29, and a fixing plate 30 is rotatably installed on the end of the fixing bolt 28 away from the turning handle 29. The fixing plate 30 is arranged in the slot 17, and two groups of mounting holes 31 are opened on one side of the fixing block 16. Slide rods 32 are slidably connected in both groups of mounting holes 31, and the slide rods 32 are fixedly installed on the fixing plate 30.

[0050] After the slot 17 is stuck on the wall of the breeding pond 1, the fixing bolt 28 is rotated by turning the handle 29, and the fixing bolt 28 pushes the fixing plate 30 to move toward the pond wall. The fixing plate 30 contacts and squeezes the pond wall, thereby fixing the fixing block 16 on the breeding pond 1, improving the stability of the water withdrawal pump when it is fixed. The sliding rod 32 cooperates with the mounting hole 31 to limit the movement of the fixing plate 30, preventing the fixing plate 30 from flipping over when the fixing bolt 28 is rotated, improving the stability of the fixing plate 30 during movement, and ensuring the fixing effect of the fixing plate 30.

[0051] Specific reference is made to the following operation: place the fixing block 16 on the wall of the culture pond 1 through the slot 17 below the fixing block 16, rotate the fixing bolt 28 by turning the turning handle 29, the fixing bolt 28 pushes the fixing plate 30 to move, the fixing plate 30 squeezes the wall of the culture pond 1 to install the fixing block 16 on the culture pond 1, place the "U"-shaped part of the De20PVC pipe 10 and the PVC fixed pipe 13 in the groove of the support block 15, so that the reducing tee 2, the De110PVC pipe 3, the eccentric reducing sleeve 4 and the De75 elbow 5 are located in the culture pond 1, turn the turntable 24, the turntable 24 drives the threaded rod 20 to rotate, and when the threaded rod 20 rotates, it pushes the two sets of slide seats 19 to move relative to each other, and the two sets of slide seats 19 pull or push the support block 15 to move vertically through the connecting rod 21, so as to adjust the position of the De75 elbow 5 in the water body, and when the De75 elbow 5 is adjusted to be 1-2 cm above the water surface according to the water depth, the insertion rod 27 is inserted into the limiting hole 25 and the slot 26 in sequence. , the plug rod 27 cooperates with the limiting hole 25 and the slot 26 to limit the rotation of the turntable 24, and the height of the adjusted De75 elbow 5 is fixed. The end of the gas supply hose 12 away from the PVC pagoda ball valve 11 is connected to the output end of the air pump of the external gas supply equipment, and the PVC pagoda ball valve 11 is opened. The gas is transported to the nano aeration tube 8 through the De20PVC tube 10, the De20 elbow 9 and the pagoda tee 7. The gas passes through the nano gaps in the nano aeration tube 8, and forms tiny bubbles inside it. The tiny bubbles rise in the De110PVC tube 3 and the eccentric reducer sleeve 4 and are discharged from the De75 elbow 5. The tiny bubbles release oxygen in the water to achieve the purpose of oxygenating the water body. At the same time, the bubbles discharged from the De75 elbow 5 promote the flow and surging of the water body, increase the contact area of ​​the water body with the air, and further increase the dissolved oxygen content of the water body. The flow of the water body can accelerate the decomposition and transformation of harmful substances in the water body, avoid the formation of dead water areas, and help keep the water quality fresh and stable.
