[0026] Reference Figure 1-Figure 4A bottom improver for aquaculture includes a fixed rod 6, on which a lower limit fixed arc plate 13 is arranged. The lower limit fixed arc plate 13 is mainly used when the bubble generating device of the device is inflated to a certain degree and emptied. Due to the weight of the hexagonal connecting rod frame 9 and the fixed rod movable sleeve 11, it will sink until it sinks to the fixed rod movable sleeve 11 and stops after contacting the lower limit fixed arc plate 13, and it is kept stable by the buoyancy of the floating ball 7 on the water surface. A fixed rod movable sleeve 11 is arranged above the lower limit fixed arc plate 13, and a hexagonal connecting rod is fixedly connected to the outer side of the fixed rod movable sleeve 11. Frame 9, a connecting rod fixing sleeve 5 is arranged on the outside of the hexagonal connecting rod frame 9, and the connecting rod fixing sleeve 5 is mainly used to connect the connecting rod 8, and the connecting rod 8 is connected inside the connecting rod fixing sleeve 5, and one end of the connecting rod 8 is connected to a floating ball 7, and the floating ball 7 is filled with 25 kg of water, and provides buoyancy to the device, so that the device can remain stable in the water without sinking, and an upper limit fixing arc plate 14 is arranged above the hexagonal connecting rod frame 9. The main function of the upper limit fixing arc plate 14 is that when the bubble generating device of the device is inflated, the buoyancy of the floating ball 7 makes the hexagonal connecting rod frame 9 and the fixed rod movable sleeve 11 in a floating state until they are in contact with each other. The upper limit fixed arc plate 14 contacts and maintains a stable state. A bubble generating device is fixedly connected below the fixed rod 6. A fixed barrel cover 2 is arranged above the bubble generating device. An air inlet 3 is arranged above the fixed barrel cover 2. The air inlet 3 is an interface for inflating the device. A bubble outlet 4 is arranged on the fixed barrel cover 2 on one side of the air inlet 3. The bubble outlet 4 is mainly used to discharge the air in the device to form a bubble discharge device. A bubble generating barrel 1 is connected below the fixed barrel cover 2. A water inlet hole (15) is arranged on the fixed barrel cover (2). The water inlet hole 15 is naturally immersed in the water body to take in air while the water inlet hole 15 also Water is introduced into the water inlet, and the bottom of the water inlet hole (15) is connected to a U-shaped pipe (16), the other end of the U-shaped pipe (16) is connected to a disc (17), and the disc (17) is arranged in the middle below the air outlet disc (18), and is simultaneously connected to an exhaust port (19) on the air outlet disc (18), the exhaust port (19) is located above the fixed barrel cover 2 and is a bubble outlet 4, the bottom of the air inlet hole (3) is connected to an air inlet pipe (301), and the air inlet pipe (301) is connected to the U-shaped pipe (16), and the air inlet hole (3) is externally connected to an inflation device to inflate air into the interior.

[0027] A first fixing nut 10 is provided on the lower limit fixed arc plate 13, and a second fixing nut 12 is provided on the upper limit fixed arc plate 14. The first fixing nut 10 and the second fixing nut 12 are used to fix the lower limit fixed arc plate 13 and the upper limit fixed arc plate 14. Three connecting rod fixing sleeves 5 are evenly arranged, three connecting rods 8 are arranged, and three floating balls 7 are arranged, and their sizes are the same. The size of the fixed rod 6 is larger than that of the connecting rod 8. There are four bubble outlets 4 around the fixed barrel cover 2. The diameter of the fixed rod movable sleeve 11 is larger than the diameter of the fixed rod 6, and the diameter of the connecting rod fixing sleeve 5 is larger than the diameter of the connecting rod 8.

[0028] Working principle: When the bubble generating device of the device is inflated to a certain degree and then emptied, the hexagonal connecting rod frame 9 and the fixed rod movable sleeve 11 will sink due to their own weight until the fixed rod movable sleeve 11 contacts the lower limit fixed arc plate 13 and stops, and the buoyancy of the floating ball 7 and the connecting rod and other components are used to keep it stable and not easy to shake or overturn;

[0029] When the bubble generating device of the device is inflated, the buoyancy of the float 7 causes the hexagonal connecting rod frame 9 and the fixed rod movable sleeve 11 to float upward until they contact the upper limit fixed arc plate 14, so that the device remains in a stable state;

[0030] The bubble generating barrel 1 passes through the aeration equipment through the air pipe and then continuously enters the container through the air inlet 3. At the same time, water also enters the container through the water inlet 15. As the air in the container increases, the buoyancy of the air lifts the three floats 7. When the air in the container reaches a certain amount (pressure), the air is discharged from the four exhaust ports 19 on the top of the container, thereby pushing the water with a large amount of bacteria or harmful substances around the container to flow to the surface of the water, thereby killing bacteria and diluting harmful substances through the killing effect of sunlight and the flow of water, thereby achieving the effect of improving the water quality. After the air in the container is exhausted, the three floats 7 sink back into the water due to their own gravity. During the process, the balance of the container is always maintained to ensure that the container does not tip over and enter the next cycle.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
