Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an aerator for aquaculture. Background Technique

[0002] An aerator is a machine commonly used in fishery aquaculture. Generally, an aerator uses its own air pump to inject air into the water to increase the oxygen content in the water. Its main function is to increase the oxygen content in the water to ensure that fish, shellfish, etc. in the water do not lack oxygen. At the same time, it can also inhibit the growth of anaerobic bacteria in the water and prevent the pond water from deteriorating and threatening the living environment of fish.

[0003] Most of the existing aerators float on the water surface through the buoyancy of floating plates and floating balls. In the actual use process, most of them adjust the buoyancy of the whole device by manually injecting water into the floating balls to facilitate meeting the aeration effect in different scenarios. This is time-consuming and laborious, and it is not easy to adjust the buoyancy. In addition, most of the existing aerators directly lead the exhaust pipe into the water, which makes the oxygen dissolution effect limited. Content of the Utility Model

The other end of the exhaust pipe 11 extends into the inside of a housing 12. The bottom surface of the floating plate 1 is welded and fixed to the housing 12. A plurality of exhaust holes are opened on the outside of the housing 12. The bottom of the housing 12 is welded and fixed to a motor 13. The output end of the motor 13 extends into the inside of the housing 12 and is welded and fixed to the bottom surface of a rotating plate 14. A plurality of stirring blades 15 are welded and fixed to the upper surface of the rotating plate 14. The stirring blades 15 are arranged in a circumferential array outside the exhaust pipe 11. The upper surface of the rotating plate 14 is welded and fixed to a rotating shaft 16. The rotating shaft 16 extends into the exhaust pipe 11 and is welded and fixed to a plurality of propellers 17. A winding roller 18 is arranged on the upper surface of the floating plate 1. The side of the winding roller 18 is connected and fixed to a driving source. A steel wire rope 19 is wound around the surface of the winding roller 18. One end of the steel wire rope 19 passes through a rectangular through hole of the floating plate 1 and then extends downward to be fixedly connected to a fixed rod. A counterweight 20 is slidably connected to the outside of the fixed rod through a circular through hole. The bottom of the fixed rod is provided with threads, and the fixed rod is threadedly connected to a plug through the threads. The counterweight 20 is fixed to the outside of the fixed rod through the plug.

[0022] A rectangular through-hole is provided on the upper surface of the floating board 1. The inner wall of the rectangular through-hole is fixedly welded to the guide rod. The steel wire rope 19 passes through the rectangular through-hole and extends below the floating board 1 and is fixedly welded to the fixed rod. A counterweight 20 is sleeved outside the fixed rod.

Vice versa, the buoyancy of the floating ball 3 is adjusted. In actual use, through the pressure sensor 9, the floating ball 3 can maintain a certain fixed buoyancy for a long time and improve the accuracy of the buoyancy adjustment of the floating ball 3;

[0023] Working principle: When in use, the staff places the overall device on the surface of the target water area. By adjusting the air pump 5, air is injected into the floating ball 3 through the connecting air pipe 6, resulting in an increase in the internal pressure of the floating ball 3, causing the piston 7 to move downward, and discharging the water at the bottom of the piston 7 from the water through-hole 8, thereby increasing the drainage volume of the floating ball 3 and the buoyancy generated by the floating ball 3. Through the cooperation of the pressure sensor 9, the buoyancy of the floating ball 3 can be adjusted more accurately. Subsequently, the number of counterweights 20 is increased or decreased to adjust the gravity of the counterweights 20. Then, the counterweights 20 are moved to the target depth by the winding roller 18. By adjusting the buoyancy of the floating ball 3 and the gravity of the counterweights 20, the stability of the overall device during oxygenation is improved. The air is made to enter the exhaust pipe 11 by the oxygenation air pump 10. The rotating plate 14 and the rotating shaft 16 are rotated by the motor 13. Further, the rotation of the propellers 17 promotes the flow of air inside the exhaust pipe 11, and together with the rotation of the stirring blades 15, a stirring effect is formed, so that the air is stirred with the water and the dissolution effect of oxygen in the air is improved.
