[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 3The utility model provides an embodiment: a fish pond aerator limit device, including an annular float 1, the annular float 1 is fixedly connected with a support rod 2, one end of the support rod 2 is fixedly connected with a sleeve 3, the outer wall of the sleeve 3 is fixedly connected with a support plate 4, and a driving mechanism is arranged on the top of the support plate 4; the sleeve 3 is rotatably connected with a main shaft 7, one end of the main shaft 7 is fixedly connected with a shell 10, and an adjusting mechanism is also arranged inside the shell 10, and the driving mechanism includes a waterproof motor 5, the bottom of the waterproof motor 5 is fixedly connected to the top of the support plate 4, and the output end of the waterproof motor 5 is fixedly connected with Transmission gear 1 6, the outer wall of the main shaft 7 is fixedly connected with transmission gear 2 8, the transmission gear 2 8 is meshed with the outer wall of the main shaft 7, the top of the main shaft 7 is fixedly connected with waterproof motor 2 9, the output end of waterproof motor 29 is fixedly connected with connecting shaft 14, the adjustment mechanism includes bevel gear 2 15, the inside of bevel gear 2 15 is fixedly connected to the outer wall of connecting shaft 14, the shell 10 is internally rotatably connected with a limit block 11, one end of the limit block 11 is fixedly connected with a stirring blade 12, the other end of the limit block 11 is fixedly connected with a bevel gear 13, and the bevel gear 13 is meshed with the outer wall of bevel gear 2 15;

[0032] Specifically, the output end of the waterproof motor 15 is tightly connected to the transmission gear 16. When the waterproof motor 15 is started, it drives the transmission gear 16 to rotate. The transmission gear 16 and the transmission gear 28 are mutually transmitted through precise gear matching, so that the transmission gear 28 rotates accordingly. As the transmission gear 28 rotates, the main shaft 7 is driven to rotate. The main shaft 7 is the core component in the device, and its rotation will further drive the stirring blade 12 to rotate in the water, thereby achieving the effect of oxygenation. In order to ensure the stability of the main shaft 7 during the rotation process, it is fixed inside the annular buoy 1 through a sleeve 3. The function of the sleeve 3 is to limit the main shaft 7 to prevent it from deflecting or shaking during the working process. In this way, the main shaft 7 can rotate stably in the annular buoy 1, ensuring that the stirring blade 12 can perform the oxygenation operation normally. When it is necessary to adjust the inclination angle of the stirring blade 12 to control the amount of oxygenation, the waterproof motor 29 starts to play a role. The output end of the waterproof motor 29 is connected to the connecting shaft 14, and when the motor is started, it drives the connecting shaft 14 to rotate. The connecting shaft 14 is connected to the bevel gear 15, so the rotation of the connecting shaft 14 will drive the bevel gear 15 to rotate together. The bevel gear 15 and the bevel gear 13 are mutually transmitted through gear meshing. When the bevel gear 15 rotates, the bevel gear 13 will also rotate. Since the bevel gear 13 is connected to the stirring blade 12, the rotation of the bevel gear 13 will drive the stirring blade 12 to adjust the angle. By adjusting the rotation angle of the bevel gear 13 and the bevel gear 15, the inclination angle of the stirring blade 12 can be accurately controlled, thereby changing the contact area between the stirring blade 12 and the water surface. After the inclination angle of the stirring blade 12 is adjusted, its rotational motion in the water will change the size of the oxygen increase. By controlling the rotation speed and direction of the waterproof motor 2 9, the oxygen increase can be accurately adjusted to adapt to different water environments and needs. In order to ensure the stability of the stirring blade 12 during rotation, it is fixed inside the housing 10 by a limit block 11. The function of the stopper 11 is to limit the range of motion of the stirring blade 12 to prevent it from excessively swinging or being damaged during operation. In this way, the stirring blade 12 can stably rotate within a limited range to achieve an effective oxygenation effect.

[0033] Reference Figure 1 and Figure 4The outer wall of the annular buoy 1 is fixedly connected to a limit ring 16, and the limit ring 16 is slidably connected to a limit column 18. The bottom of the limit column 18 is fixedly connected to a base 17, and a slot 19 is provided inside the limit column 18. The limit plate 23 is slidably connected to the limit plate 23, and a limit slot 24 is provided inside the limit plate 23. A clamping block 20 is fixedly connected to one side of the limit plate 23, and the outer wall of the clamping block 20 is embedded in the slot 19. A slider 25 is fixedly connected to the limit ring 16, and the outer wall of the slider 25 is slidably connected to the limit slot 24. A telescopic rod 21 is arranged inside the limit ring 16, and a spring 22 is sleeved on the outer wall of the telescopic rod 21. One end of the telescopic rod 21 and the spring 22 are fixedly connected to the other side of the limit plate 23, and the other end of the telescopic rod 21 and the spring 22 are fixedly connected to the inside of the limit ring 16;

[0034] Specifically, at the bottom of the fish pond, the base 17 is first fixed to ensure its stability. Next, the annular buoy 1 is installed on the outer wall of the limiting column 18 through the limiting ring 16. The inside of the annular buoy 1 is a hollow design, which provides sufficient buoyancy in the water, so that the annular buoy 1 can float stably on the water surface. At the same time, the block 20 in the limiting ring 16 is cleverly embedded in the slot 19. This design enhances the stability of the annular buoy 1 and keeps its position unchanged even when the wind force on the water surface is strong. It is worth mentioning that the block 20 is limited inside the limiting ring 16 by the limiting plate 23, which further enhances the stability of the annular buoy 1. The limiting plate 23 slides and limits on the outer wall of the slider 25 through the limiting groove 24 opened inside, ensuring the stability of the block 20 in the slot 19. In the whole process, the tension of the spring 22 plays a key supporting role, which makes it difficult for the block 20 to slide out when it is embedded in the slot 19. When the wind force on the water surface is strong, the annular buoy 1 can be limited on the outer wall of the limiting column 18. This design provides a self-locking function, effectively reducing the ups and downs of the annular buoy 1 on the water surface and ensuring its stability.

[0035] Working principle: When the fish pond aquaculture aerator limiting device is used, the base 17 is first fixed to the bottom of the fish pond, and then the annular buoy 1 is limited on the outer wall of the limiting column 18 through the limiting ring 16. The inside of the annular buoy 1 is hollow and can provide buoyancy on the water surface. The block 20 in the limiting ring 16 is embedded in the groove 19. The block 20 is limited in the limiting ring 16 through the limiting plate 23. The limiting plate 23 slides and limits on the outer wall of the slider 25 through the limiting groove 24 opened inside, and is supported by the tension of the spring 22, so that the block 20 is not easy to slide out when it is embedded in the groove 19. When the wind force on the water surface is large, the annular buoy 1 can be limited on the outer wall of the limiting column 18, which can provide self-locking to reduce the ups and downs of the annular buoy 1. Then, the output end of the waterproof motor 5 drives the transmission gear 6 to rotate, and the transmission gear 6 drives the main shaft 7 to rotate through the transmission gear 2 8, and the main shaft 7 then drives the stirring blade 12 to rotate in the water to increase oxygen. The main shaft 7 is limited in the annular buoy 1 by the sleeve 3. When it is necessary to control the inclination angle of the stirring blade 12 to adjust the amount of oxygen increase, the output end of the waterproof motor 29 drives the connecting shaft 14 to rotate, and the connecting shaft 14 drives the bevel gear 2 15 to rotate. The bevel gear 2 15 drives the stirring blade 12 to rotate through the bevel gear 13 to adjust the inclination angle of the stirring blade 12, thereby changing the contact area between the stirring blade 12 and the water surface to achieve the effect of controlling the amount of oxygen increase. The stirring blade 12 is limited in the shell 10 by the limit block 11.
