[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 4The utility model provides an embodiment: an oxygenating device for high-density aquaculture, comprising a water tank 1, a fixed block 2 is fixedly connected to the top of the water tank 1, a motor 3 is fixedly connected to the top of the fixed block 2, a turntable 4 is fixedly connected to the output end of the motor 3, a connecting rod 5 is fixedly connected to the outer side of the turntable 4, a hollow shell 6 is slidably connected to the outer side of the connecting rod 5, a protective tube 7 is fixedly connected to the bottom of the hollow shell 6, a plurality of joints 8 are fixedly connected to the outer side of the protective tube 7, a plurality of jet heads 9 are fixedly connected to the bottom of the joint 8, a jet head 9 is fixedly connected to the outer side of the protective tube 7, an oxygenator 12 is fixedly connected to the bottom end of the jet head 9, an air pump 11 is arranged at the lower part of the outer side of the jet head 9, an activated carbon filter 13 is slidably connected to the inside of the water tank 1, two fixed components are arranged on the outer side of the water tank 1, a water inlet pipe 25 is fixedly connected to the middle part of the left side of the water tank 1, a water pump 24 is arranged on the outer side of the water inlet pipe 25, a water outlet pipe 22 is fixedly connected to the middle part of the right side of the water tank 1, and a water pump 1 21 is arranged on the outer side of the water outlet pipe 22.

[0032] Specifically, first, the worker opens valve 1 20, and introduces the aquaculture water from the outlet pipe 22 into the water tank 1 through the water pump 1 21. The activated carbon filter 13 filters impurities and harmful substances in the process to improve the water quality. Subsequently, the air valve 10 is opened, and the air pump 11 is started. Oxygen is accurately delivered from the oxygen generator 12 through the nozzle 9, the protective tube 7 and the joint 8 to ensure that the oxygen is evenly distributed in the water in the water tank 1 to support the breathing of the organism. In order to achieve uniform oxygenation, the worker starts the drive device motor 3, and the turntable 4 rotates accordingly, driving the connecting rod 5 to reciprocate in the hollow shell 6, so that the hollow shell 6, the protective tube 7, the joint 8 and the nozzle 9 move up and down accordingly, thus ensuring that the oxygen is more evenly distributed in the water tank 1. After the oxygen flushing is completed, the valve 2 23 is opened, and the water pump 2 24 is started to return the treated water to the aquaculture area to form a complete water circulation system, which not only ensures the water quality, but also saves water resources and improves the aquaculture efficiency.

[0033] Reference Figure 2 and Figure 3 The fixed component includes a thin shell 14, the outer side of the thin shell 14 is fixedly connected to the outer side of the water tank 1, a paddle rod 16 is slidably connected to the middle side of the inner part of the thin shell 14, a baffle 18 is fixedly connected to one side of the outer side of the paddle rod 16, a spring 19 is provided on the other side of the outer side of the paddle rod 16, a thin shell 2 15 is fixedly connected to the upper part of the thin shell 14, and a blocking block 17 is provided on the top of the baffle 18.

[0034] Specifically, during the maintenance of the activated carbon filter 13, if disassembly is required, the operator only needs to gently push the paddle rod 16 to cause the baffle 18 to move outward. In this process, the spring 19, as a key component, stores energy through compression, so that the blocking block 17 slides into the thin shell 14 along its force, forming a barrier to prevent the baffle 18 from retracting, thereby ensuring the safety of the disassembly process. After completing its task, the paddle rod 16 will automatically withdraw from the inside of the activated carbon filter 13 for easy operation. On the contrary, when the filter needs to be replaced, it is only necessary to lift the blocking block 17 upward to separate it from the thin shell 14, and the elastic restoring force of the spring 19 will drive the baffle 18 back to its initial position. At this time, the paddle rod 16 can be smoothly reinserted into the activated carbon filter 13 to complete the installation of the filter. This design not only ensures the ease of operation, but also ensures the reliability of the equipment and the high efficiency of filter replacement.

[0035] Reference Figure 1 , Figure 2 and Figure 4 The outer side of the upper part of the protective tube 7 is slidably connected to the inside of the water tank 1, one end of the spring 19 is fixedly connected to the middle of the baffle 18, and the other end of the spring 19 is fixedly connected to the inner wall of the thin shell 14, the paddle rod 16 penetrates the water tank 1 and is inserted into the activated carbon filter 13, the outer side of the baffle 18 is slidably connected to the inside of the thin shell 14, the upper side of the blocking block 17 is slidably connected to the inside of the thin shell 2 15, and the lower side of the blocking block 17 is slidably connected to the inside of the thin shell 14, a valve 23 is arranged on the outer side of the water inlet pipe 25, a valve 20 is arranged on the outer side of the water outlet pipe 22, and an air valve 10 is arranged on the lower part of the outer side of the jet head 9.

[0036] Specifically, the protective tube 7 is cleverly installed in the upper part of the water tank 1 to ensure the smooth transmission of water flow and gas. The spring 19 plays a key balancing and buffering role. One end is fixed to the middle of the baffle 18, and the other end is embedded in the inner wall of the thin shell 14, ensuring the movement accuracy of the baffle 18. The paddle rod 16 penetrates the water tank 1 and penetrates into the activated carbon filter 13, making the disassembly and assembly of the activated carbon filter 13 convenient. The baffle 18 can slide in the thin shell 14 as needed, and its outer structure ensures the flexibility of operation. The blocking block 17 is distributed between the thin shell 14 and the thin shell 2 15, which prevents the baffle 18 from retracting and ensures the safe disassembly process. The water inlet pipe 25 and the water outlet pipe 22 are respectively equipped with valve 2 23 and valve 1 20, allowing workers to accurately control the inflow and outflow of water. The air valve 10 is provided below the jet head 9 to facilitate the control of the oxygen supply, ensuring the accurate delivery of gas and the oxygenation effect of the water body.

[0037] Working principle: workers open valve 20, drive water pump 21, pump the water in the aquaculture into the water outlet pipe 22, enter the water tank 1, and absorb impurities and harmful substances in the water through the activated carbon filter 13 to improve the water quality. At this time, open the air valve 10, drive the air pump 11, and finally transport the oxygen in the oxygen generator 12 to the jet head 9 through the jet head 9, the protective pipe 7 and the joint 8, and spray it into the water in the water tank 1. In order to make the oxygenation more uniform, the motor 3 is driven at this time to drive the turntable 4 to rotate, and then drive the connecting rod 5 to reciprocate in the hollow shell 6, and then drive the hollow shell 6 to move up and down, and then drive the protective pipe 7, the joint 8 and the jet head 9 to move up and down, and the jet heads 9 on the two adjacent groups of joints 8 branches are staggered, so that the water The water in tank 1 is oxygenated more evenly. After the oxygenation is completed, valve 23 is opened to drive water pump 24 to transport the water to the aquaculture water to form a water cycle. When the activated carbon filter 13 needs to be disassembled, the paddle rod 16 is pushed to move the baffle 18 outward, thereby compressing the spring 19, so that the blocking block 17 slides into the thin shell 14 to prevent the baffle 18 from moving inward. At this time, the paddle rod 16 is completely separated from the inside of the activated carbon filter 13, and the disassembly is completed. When a new activated carbon filter 13 needs to be installed, the blocking block 17 is pulled upward. At this time, the blocking block 17 leaves the thin shell 14, and the baffle 18 moves inward under the push of the elastic force of the spring 19, and then the paddle rod 16 is reinserted into the inside of the activated carbon filter 13, and the installation is completed.
