Description

Technical Field

[0001] The utility model belongs to the technical field related to aquaculture, and in particular relates to an aeration device for culturing large yellow croaker in saline-alkali land. Background Art

[0002] Aeration devices are usually used to improve the water quality environment and ensure the healthy growth of large yellow croaker in saline-alkali land. Aeration devices increase the oxygen content in the water by injecting air into the water, promote the dissolution of oxygen in the water, increase the oxygen content in the water body, and improve the water quality. This device usually includes components such as an air pump, an air pipe, and an air stone. The air is compressed by the air pump and transported into the water through the air pipe, and then the bubbles are released through the air stone, thereby increasing the oxygen content in the water and improving the dissolved oxygen level in the water body.

[0003] At present, aquaculture in saline-alkali land faces some challenges, including land quality, water resources, salinity, soil acidity and alkalinity. The soil quality of saline-alkali land is usually poor, with high salt content and alkaline pH, which have a certain impact on fish farming. In addition, water resources in saline-alkali land are relatively scarce, and water resources need to be used more rationally during the aquaculture process. In order to cope with these challenges, farmers usually take a series of measures, such as reasonably selecting fish species suitable for saline-alkali land, strengthening water quality management, and improving soil environment, to improve aquaculture efficiency and sustainability.

The aeration pipe 5 is provided with a tail end connecting frame 8 at the right end, and the tail end connecting frame 8 is arranged parallel and symmetrically with the gas collecting pipe 4. The top of the aeration pipe 5 is provided with a plurality of internal thread joints 6 at equal distances, and the internal thread joints 6 are connected with an aeration head 7. The design of the internal thread joints 6 and the aeration head 7 allows the aeration head 7 to be conveniently installed on the aeration pipe 5, and the angle and position of the aeration head 7 can be flexibly adjusted to ensure that the bubbles can be fully dispersed in the water, thereby improving the gas utilization rate. The aeration head 7 is connected to the inside of the aeration pipe 5 through the internal thread joint 6, and the front and rear ends of the gas collecting pipe 4 and the tail end connecting frame 8 are fixed on the outside. A fixing ring 11 is fixed, a fixing bracket 10 is welded to the bottom end of the fixing ring 11, and a mounting base plate 9 is welded to the bottom end of the fixing bracket 10. The fixing devices such as the fixing bracket 10 and the mounting base plate 9 enable the aeration device to be firmly fixed inside the breeding box, and are not easily affected by the impact of external water flow or water quality, thereby ensuring the stability and durability of the aeration device.

[0028] like Figure 1 and Figure 2As shown, when installing and using the aeration device for breeding large yellow croaker in saline-alkali land, it is first necessary to place the interconnected gas collecting pipe 4, aeration branch pipe 5 and tail end connecting frame 8 to the bottom of the saline-alkali land breeding pond. At this time, the fixing brackets 10 at the bottom of the front and rear ends of the gas collecting pipe 4 and the tail end connecting frame 8 are both attached to the bottom ground of the breeding pond through the installation bottom plate 9, and then the installation bottom plate 9 is firmly fixed to the bottom ground of the breeding pond.

On the inner wall of the side, the top of the air supply pipe 2 is located at the top of the saline-alkali land breeding pond, and then the left end of the top of the air supply pipe 2 needs to be connected and fixed to the aeration pump box 1, and then the aeration pump inside the aeration pump box 1 needs to be powered on. When the aeration pump is running, air will be supplied to multiple aeration branch pipes 5 through the air supply pipe 2 and the air collecting pipe 4, and finally the gas will be filled into the water body of the saline-alkali land breeding pond in the form of bubbles through the aeration head 7, thereby achieving the purpose of aerating the water body of the saline-alkali land breeding pond.

[0029] like Figure 1 and Figure 3As shown, a debris blocking device 3 is arranged on the upper side of the gas collecting pipe 4, multiple aeration branch pipes 5 and the tail end connecting frame 8. The debris blocking device 3 includes a metal frame 13, a debris blocking net 14 and a metal counterweight bar 15. The metal frame 13 is horizontally arranged on the upper side of the gas collecting pipe 4, multiple aeration branch pipes 5 and the tail end connecting frame 8. The design of the metal frame 13 provides a solid supporting structure that can effectively support the debris blocking net 14, and has strong corrosion resistance and durability, and is suitable for long-term use in saline-alkali land environments. The debris blocking net 14 is fixed inside the frame of the metal frame 13, and the arrangement of the debris blocking net 14 can be The invention can effectively prevent impurities such as debris and waste from entering the aeration device, protect the normal operation of the aeration device, reduce the frequency of cleaning and maintenance, and extend the service life of the aeration device. A plurality of metal weight bars 15 are fixed to the top of the metal frame 13 and the debris blocking net 14. The setting of the weight bars enables the debris blocking net 14 to maintain a stable tension and shape, ensures the durability and reliability of the blocking effect, and also increases the weathering resistance of the debris blocking net 14. The debris blocking device 3 also includes a metal plug rod 12 and a plug rod baffle 16. Four metal plug rods 12 are provided, and the four metal plug rods 12 are respectively welded to the bottom of the metal frame 13. At the four corners, a rod baffle 16 is arranged on the upper outer side of the center of the metal rod 12. The rod baffle 16 is fixedly connected to the metal rod 12 by welding. The metal rod 12 and the rod baffle 16 are combined with the metal frame 13 to increase the stability and reliability of the entire debris blocking device 3, which can effectively resist the impact of external water flow or other external forces, and ensure the safe operation of the aeration device.

The conical design of the bottom end of the metal plug rod 12 makes it easier for the plug rod to penetrate into the soil or other fixed objects, increasing the stability and firmness of the device, ensuring the long-term stable operation of the debris blocking device 3. In summary, this debris blocking device 3 can effectively protect the aeration device from interference from debris, ensure the continuous and stable aeration effect, provide a good water quality environment for breeding large yellow croaker in saline-alkali land, and reduce the maintenance cost and workload of the breeder.

[0030] like Figure 1 and Figure 3As shown, after the aeration device is installed to the bottom of the saline-alkali land breeding pond, the air collecting pipe 4, the aeration branch pipe 5 and the tail end connecting frame 8 are fixed in parallel to the bottom of the pond. At this time, the debris blocking device 3 needs to be installed on the upper side of the air collecting pipe 4, the aeration branch pipe 5 and the tail end connecting frame 8. Specifically, the metal frame 13 with the debris blocking net 14 inside needs to be placed parallel to the upper side of the air collecting pipe 4, the aeration branch pipe 5 and the tail end connecting frame 8, and then the metal plug rods 12 at the four corners of the bottom of the metal frame 13 are directly inserted into the saline-alkali land breeding pond until the plug rod baffles 16 on the metal plug rods 12 are blocked by the bottom of the saline-alkali land breeding pond. In this way, the metal frame 13 and the debris blocking net 14 will be installed on the upper side of the air collecting pipe 4, the aeration branch pipe 5 and the tail end connecting frame 8, and then the metal frame 13 and the debris blocking net 14 will be installed on the upper side of the air collecting pipe 4, the aeration branch pipe 5 and the tail end connecting frame 8. Because a plurality of metal counterweight bars 15 are installed on the metal frame 13 and the debris blocking net 14, the metal counterweight bars 15 can apply weight on the top of the metal frame 13 to prevent the metal frame 13 and the debris blocking net 14 from being easily broken open during aeration. When feeding the large yellow croaker, the feed residues will naturally fall down, which will cause the feed residues to fall on the debris blocking net 14, preventing excessive attachment of the feed residues to the aeration device and causing blockage. When the aeration device is aerated, the bubbles generated will break open the feed residues on the debris blocking net 14, and the feed residues will be re-flowed into the water body for the large yellow croaker to eat the feed residues, thereby avoiding waste of feed and preventing excessive feed residues from polluting the aquaculture water body.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
