[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a speed control device for a water-based photovoltaic aerator, comprising a speed control box 1, a motor 2 fixedly connected inside the speed control box 1, a lead screw 3 fixedly installed at the output end of the motor 2, the outer wall of the lead screw 3 rotatably connected to the inside of the speed control box 1, a threaded sleeve 4 threadedly connected to the outer wall of the lead screw 3, a limit ring 5 fixedly connected to the outer wall of the threaded sleeve 4, a limit post 6 slidably connected inside the limit ring 5, the outer wall of the limit post 6 fixedly connected to the inside of the speed control box 1, a second motor 7 fixedly connected inside the speed control box 1, a conical cylinder 8 fixedly installed at the output end of the second motor 7, the outer wall of the conical cylinder 8 slidably connected to the outer wall of the limit ring 5, a connecting post 9 fixedly connected to the outer wall of the conical cylinder 8, the outer wall of the connecting post 9 rotatably connected to the inside of the speed control box 1, an impeller 10 fixedly connected to the outer wall of the connecting post 9, and a sealing assembly provided on the outer wall of the speed control box 1.

[0024] Specifically, the speed control box 1 fixes the motor 2. Starting the motor 2 drives the lead screw 3 to rotate inside the speed control box 1. Simultaneously, the lead screw 3 moves the threaded sleeve 4, which in turn moves the limiting ring 5 against the outer wall of the limiting post 6. The outer wall of the limiting ring 5 provides friction against the conical cylinder 8. The tapered cylinder 8's shape, gradually widening, increases friction as the limiting ring 5 slides, thus slowing down the conical cylinder 8. The speed control box 1 then controls the motor 7... It serves a fixing function. By starting motor 7, the conical cylinder 8 can be rotated, which in turn drives the connecting column 9 to rotate, which in turn drives the impeller 10 to rotate. The thrust generated by the rotation of the impeller 10 propels the water flow, achieving water flow and oxygenation. It is suitable for water bodies such as rivers and ponds with poor water flow performance and weak natural reoxygenation capacity. It can effectively improve the water flow and dissolved oxygen content, improve the hypoxic state of the water body, provide sufficient oxygen for aquatic organisms, promote the growth and reproduction of aquatic organisms, and enhance the self-purification capacity of the water body.

[0025] Reference Figure 4 The sealing assembly includes a sealing plate 12, the outer wall of which is connected to the inside of the speed control box 1, and a locking block 13 is slidably connected inside the sealing plate 12.

[0026] Specifically, the sealing plate 12 serves to seal the gearbox 1 and prevent water from entering. The sealing plate 12 has a locking block 13 inside, which can lock the gearbox 1 in place.

[0027] Reference Figure 4 The outer wall of the locking block 13 is fixedly connected to a sliding column 14, the outer wall of the sliding column 14 is slidably connected to the inside of the sealing plate 12, and a first spring 15 is provided on the outer wall of the sliding column 14. One end of the first spring 15 is fixedly connected to the inside of the sealing plate 12, and the other end of the first spring 15 is fixedly connected to the outer wall of the locking block 13.

[0028] Specifically, the locking block 13 can drive the sliding column 14 to slide, and the sliding column 14 can play a limiting role by sliding inside the sealing plate 12. The locking block 13 can drive the first spring 15 to be compressed, and the first spring 15 can play a rebound role by driving the locking block 13 to slide inside the speed control box 1.

[0029] Reference Figure 3 and Figure 4A dissolved oxygen sensor 11 is installed on the outer wall of the speed control box 1. A mounting block 16 is fixedly connected to the outer wall of the speed control box 1. A push block 17 is slidably connected inside the mounting block 16. The outer wall of the push block 17 is slidably connected to the inside of the speed control box 1. A sliding column 18 is fixedly connected to the outer wall of the push block 17. A push plate 20 is fixedly connected to the outer wall of the sliding column 18. A connecting plate 19 is fixedly connected to the outer wall of the sliding column 18. The outer wall of the connecting plate 19 is slidably connected to the inside of the mounting block 16. A fixing plate 22 is slidably connected to the outer wall of the sliding column 18. The outer wall of the fixing plate 22 is fixedly connected to the inside of the mounting block 16. A second spring 21 is installed on the outer wall of the sliding column 18. One end of the second spring 21 is fixedly connected to the outer wall of the connecting plate 19, and the other end of the second spring 21 is fixedly connected to the outer wall of the fixing plate 22.

[0030] Specifically, the dissolved oxygen sensor 11 installed on the outer wall of the speed control box 1 is used to test the dissolved oxygen content in the water. The speed control box 1 fixes the mounting block 16. Pushing the push plate 20 can drive the sliding column 18 to slide inside the mounting block 16. The sliding column 18 can drive the connecting plate 19 to slide inside the mounting block 16. The connecting plate 19 can drive the second spring 21 to compress. The second spring 21 rebounds and drives the sliding column 18 to slide inside the fixed plate 22. The sliding column 18 can drive the push block 17 to slide. The push block 17 can squeeze the locking block 13, thereby causing the locking block 13 to slide out from inside the speed control box 1, achieving the effect of quick disassembly of the sealing plate 12.

[0031] Working principle: When the speed regulating device is needed, the speed of the photovoltaic aerator is first adjusted according to parameters such as dissolved oxygen content, water level change, and water quality. The starting motor 7 drives the conical cylinder 8 to rotate, which in turn drives the connecting column 9 to rotate, and at the same time drives the impeller 10 to rotate, so as to realize the water flow and oxygenation. The starting motor 2 drives the lead screw 3 to rotate inside the speed regulating box 1, which in turn drives the threaded sleeve 4 to move. While the threaded sleeve 4 moves, it can drive the limiting ring 5 to slide on the outer wall of the limiting column 6. During the sliding process of the limiting ring 5, the friction between the limiting ring 5 and the conical cylinder 8 can achieve the effect of adjusting the speed of the conical cylinder 8.

[0032] When the sealing plate 12 needs to be removed from the speed control box 1, pressing the push plate 20 can drive the sliding column 18 to slide inside the mounting block 16, thereby driving the connecting plate 19 to slide inside the mounting block 16. At the same time, the second spring 21 is compressed, which in turn drives the sliding column 18 to slide inside the fixed plate 22. Simultaneously, the push block 17 slides inside the speed control box 1, thereby driving the locking block 13 to slide out of the speed control box 1. While the locking block 13 is sliding, the sliding column 14 can slide inside the sealing plate 12, while the first spring 15 is compressed, achieving the effect of quickly removing the locking block 13 for maintenance and upkeep of internal components. This device can not only adjust the speed of the impeller 10, avoiding unnecessary energy waste and reducing operating costs, but also quickly remove the sealing plate 12, facilitating timely maintenance and replacement of internal machinery.

[0033] 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.
