Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-6This utility model provides an impeller-type fishpond aerator: It includes a shell 1, a base 2 fixedly connected to the bottom of the shell 1, an external gear ring 3 rotatably connected to the outer wall of the base 2, a drive assembly on the shell 1 capable of driving the external gear ring 3 to rotate, a drive motor 4 fixedly connected to the top of the base 2, the output end of the drive motor passing through the base 2 and fixedly connected to a mounting plate 5, an agitator on the mounting plate 5, several connecting rods 6 fixedly connected to the outer wall of the shell 1, fixing assemblies on the connecting rods 6, threaded holes 7 on the base 2, several mounting grooves 8 on the top of the base 2, mounting seats 9 movably mounted on each mounting groove 8, and fixing bolts 10 threadedly connected to the mounting seats 9 to the threaded holes 7. The top of the shell 1 is semi-elliptical, the outer wall is cylindrical, and the mounting base 9 is L-shaped. The mounting base 9 can be easily aligned through the mounting groove 8 on the top of the disc, making it easy to fix the device with the fixing bolts 10. Through the coordinated use of the external toothed ring 3, the mounting base 9, the guardrail 23, and the drive assembly, it can prevent aquatic plants and other impurities from getting stuck in the impeller 16, and also prevent fish and shrimp from being drawn in during agitation, ensuring the safety of aquatic life. Furthermore, the drive assembly can effectively remove aquatic plants, dead leaves, and other impurities from the guardrail 23, preventing debris from accumulating and causing blockages. Even if the device runs for a long time, the guardrail 23 can remain relatively clean, avoiding a decrease in oxygenation efficiency due to blockages, and also extending the service life of the aerator.

[0034] The drive assembly includes a protective cover 11 fixedly installed on the outer wall of the housing 1. A second drive motor 12 is fixedly installed on the inner wall of the protective cover 11. The output end of the second drive motor 12 passes through the protective cover 11 and is fixedly connected to a gear 13. The gear 13 meshes with the external gear ring 3. By setting the protective cover 11, the second drive motor 12 can be protected from water ingress. The water flow can also carry away the heat generated during operation by contacting the housing 1 of the protective cover. The agitator includes several through holes 14 opened on the top of the mounting plate 5. A threaded rod 15 is movably installed inside the through hole 14. An impeller 16 is fixedly connected to the bottom of the threaded rod 15. By setting the through hole 14, the threaded rod 15 can pass through and be fixed, and it is also convenient to align during assembly. A nut 17 is threadedly connected to the outer wall of the threaded rod 15. By setting the nut 17, the threaded rod 15 can be firmly fixed, so that the impeller 16 cannot fall off when rotating.

[0035] The fixing assembly includes a float 18, with a mounting cylinder 19 fixedly connected to the top of the float 18. The outer wall of the mounting cylinder 19 has a groove 20, and the connecting rod 6 is movably installed in the groove 20. By setting the groove 20, the connecting rod 6 can be quickly aligned with the float 18. Both the mounting cylinder 19 and the connecting rod 6 have two mounting holes 21, and the two mounting holes 21 are internally threaded with a rotating screw 22. By rotating the screw 22, the mounting cylinder 19 and the connecting rod 6 can be firmly installed together. A guardrail 23 is fixedly connected to one side of the mounting base 9. By setting the guardrail 23, safety can be improved, foreign objects can be prevented from entering the impeller 16, and the service life of the equipment can be extended. Two scrapers 24 are fixedly connected to the bottom of the external toothed ring 3. The scrapers 24 are spiral-shaped and can clean the outer wall of the guardrail 23 when rotating.

[0036] Working principle: First, before use, place the impeller 16 under the mounting plate 5, then align the threaded rod 15 with the through hole 14 on the mounting plate 5, move the impeller 16 so that the threaded rod 15 passes through the through hole 14, and then tighten the nuts 17 one by one to fix the impeller 16 on the drive motor 4. Then, place the guardrail 23 under the base plate 2 so that the mounting seat 9 passes through the mounting groove 8. After alignment, insert the fixing bolt 10 into the threaded hole 7, and then tighten the fixing bolt 10 to fix the guardrail 23. At the same time, align the groove 20 on the float 18 with the connecting rod 6 in sequence, so that the connecting rod 6 and the mounting hole 21 on the mounting cylinder 19 are aligned with each other. Then, insert the rotating screw 22 into the mounting hole 21 and tighten it to connect the threads, so that the float 18 is fixed in sequence. The device can then be placed on the fishpond. When it is necessary to clean or maintain the guardrail 23, impeller 16 and float 18, the device that needs to be maintained and cleaned can be easily removed by twisting the above components in the opposite direction, making it convenient for staff to use.

[0037] After the fishpond is placed, drive motor 4 can be started. The output end rotates to drive impeller 16 to rotate, thereby aerating the fishpond. During the aeration process, the guardrail 23 can block aquatic plants and other impurities and prevent impeller 16 from stirring and killing fish and shrimp. After running for a period of time, aquatic plants and dead leaves will get stuck on the guardrail 23. At this time, drive motor 12 can be started. The output end drives gear 13 to rotate, causing the outer gear ring 3 to rotate. The two scrapers 24 scrape and clean the outer wall of the guardrail 23, keeping the guardrail 23 relatively clean and preventing it from becoming clogged after running for a period of time, which would reduce the aeration efficiency of impeller 16 and affect the aeration of the fishpond.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
