Description

Technical Field

[0001] This utility model relates to the field of aeration equipment technology, and in particular to a fountain aeration device. Background Technology

[0002] In the field of aquatic ecological environment management and landscape maintenance, fountain aeration equipment plays a crucial role. Whether it's urban landscape lakes, artificial water systems in parks, or oxidation ponds in sewage treatment plants, prolonged stagnant water can easily lead to insufficient dissolved oxygen levels, causing water quality deterioration and algae growth. This not only affects the appearance of the water body but also disrupts the aquatic ecological balance. Fountain aeration equipment, by agitating the water flow and promoting air-water mixing, can effectively increase the dissolved oxygen concentration in the water, enhance the water body's self-purification capacity, inhibit the reproduction of harmful microorganisms, and maintain water clarity and ecological health. Among them, the inverted umbrella-shaped aerator, with its unique structural design, can create a large-scale water circulation during rotation, resulting in high air-water mixing efficiency, and is widely used in various aquatic environments.

[0003] However, existing inverted umbrella-shaped aerators have significant drawbacks. Their aeration impeller height is typically fixed, making it difficult to adapt to water depths. For example, in some scenic lakes with significant seasonal water level fluctuations, when the water level drops, the fixed-height aerator impeller is too close to the water surface, limiting the aeration range and reducing air-water mixing efficiency; conversely, when the water level rises, the impeller is submerged too deeply, reducing aeration efficiency and increasing energy consumption. Utility Model Content

[0004] To address the technical problem that the height of the aeration impeller in existing inverted umbrella-shaped aerators is usually fixed, this utility model provides a fountain aeration device.

[0017] The following is in conjunction with the appendix Figure 1-8 The present invention will be further described below.

[0018] To address the problems existing in the background technology, this application proposes the following technical solution: A fountain aeration device includes a drive motor 1 and an inverted umbrella-shaped stirring blade 4. A rotating rod 2 is fixedly connected to the output end of the drive motor 1. A rotating shaft 3 is fixedly connected to the top of the inverted umbrella-shaped stirring blade 4. A square rod 9 is fixedly connected to the top of the rotating shaft 3. A rubber sleeve is fitted around the square rod 9, and the square rod 9 slides in conjunction with a rectangular sliding hole. The rotating rod 2 has a rectangular sliding hole for the square rod 9 to slide through, and a fixing component is provided on the outside of the rotating rod 2 for fixing the square rod 9. The drive motor 1, as the power core of the device, adopts a high-efficiency and energy-saving motor, capable of stable power output, driving the rotating rod 2 to rotate continuously. The rotating rod 2 is tightly fixedly connected to the output end of the drive motor 1 to ensure reliable power transmission. The inverted umbrella-shaped stirring blade 4 is a key component for realizing the aeration function. Its unique inverted umbrella shape design effectively disturbs the water flow during rotation, increasing the contact area between water and air, thereby improving the aeration effect. The inverted umbrella-shaped stirring blade 4 is connected to the square rod 9 via the rotating shaft 3. The rubber sleeve on the outside of the square rod 9 serves multiple purposes: on the one hand, the rubber sleeve has good buffering performance, which can reduce the transmission of vibration generated when the stirring blade rotates to the rotating rod 2, reduce the operating noise of the equipment, and protect the connecting parts from vibration damage; on the other hand, the rubber sleeve increases the friction between the square rod 9 and the rectangular sliding hole, so that the square rod 9 is not easy to slide on its own due to water flow impact or equipment vibration after the height is adjusted, thus ensuring the stability of the stirring blade position.

[0019] The rectangular sliding hole in the rotating rod 2 provides a sliding track for the square rod 9, allowing operators to flexibly adjust the height of the inverted umbrella-shaped mixing blades 4 according to actual needs. Whether in shallow landscape pools or deep lake areas, the mixing blades can be adjusted to the appropriate depth by sliding the square rod 9 to achieve optimal aeration. The fixing component on the outside of the rotating rod 2 is crucial for ensuring the fixed height of the mixing blades. After height adjustment, the fixing component firmly secures the square rod 9, preventing displacement during equipment operation and ensuring the stability and continuity of aeration. This adjustable height design, compared to traditional fixed-height aeration equipment, better adapts to different aquatic environments, significantly improving the equipment's versatility and practicality.

[0020] In this embodiment, the square rod 9 has multiple sets of positioning holes 10 on its exterior, and the rotating rod 2 has at least one positioning hole 10 on its exterior. The fixing component is a positioning pin 12 that is slidably connected in the positioning hole 10. An arc-shaped plate 13 is fixedly connected to the exterior of the positioning pin 12. The arc-shaped plate 13 is fitted into the through hole 11. Both the exterior of the rotating rod 2 and the exterior of the arc-shaped plate 13 are provided with external threads. A nut 16 is connected to the external thread of the rotating rod 2. The multiple sets of positioning holes 10 on the square rod 9 provide multiple fixed points for adjusting the height of the inverted umbrella-shaped stirring blade 4. The operator can select the appropriate positioning hole 10 for fixing according to the specific water depth and aeration requirements to achieve precise height adjustment. As the core component for fixing the square rod 9, the positioning pin 12 can be easily inserted into the positioning holes 10 of the square rod 9 and the rotating rod 2 to achieve quick connection between the two. The arc-shaped plate 13 fixed externally to the positioning pin 12 matches the through hole 11 on the rotating rod 2. When the positioning pin 12 is inserted into the positioning hole 10, the arc-shaped plate 13 can be tightly fitted into the through hole 11, increasing the contact area between the positioning pin 12 and the rotating rod 2 and improving the firmness of the fixation.

[0021] The external thread design of the rotating rod 2 and the arc-shaped plate 13, combined with the use of the nut 16, further enhances the fixing effect. After the positioning pin 12 is inserted into the positioning hole 10, the nut 16 is screwed onto the outside of the rotating rod 2. The external thread of the nut 16 and the arc-shaped plate 13 mesh with each other. As the nut 16 is continuously tightened, the inner wall of the nut 16 will generate a continuous resistance force against the arc-shaped plate 13, thereby firmly fixing the positioning pin 12 in the positioning hole 10 of the square rod 9 and the rotating rod 2. Even if the equipment operates for a long time, the positioning pin 12 will not loosen or fall off under the impact and vibration of the water flow. Compared with the traditional simple plug-and-play fixing, this threaded fastening method has stronger stability and reliability, effectively avoiding the situation where the stirring blades fall off or shift due to insecure fixing, ensuring the safe operation of the fountain aeration equipment, and also reducing the frequency of equipment maintenance and repair costs.

[0022] In this embodiment, a fixing ring 5 is fixedly connected to the outside of the rotating rod 2. At least one sliding rod 6 is slidably connected through the fixing ring 5. A spring 7 is sleeved on the outside of the sliding rod 6, and the spring 7 acts as a buffer. An abutment ring 8 is fixedly connected to the bottom of the sliding rod 6, and a positioning post 15 is fixedly connected to the bottom of the abutment ring 8. A positioning groove 14 is provided on the top of the nut 16. The fixing ring 5 fixedly connected to the outside of the rotating rod 2 provides stable support and a sliding track for the sliding rod 6. The sliding rod 6 can slide freely in the fixing ring 5, which facilitates the operator to adjust the abutment ring 8 according to the position of the nut 16. The positioning post 15 at the bottom of the abutment ring 8 cooperates with the positioning groove 14 at the top of the nut 16. After the nut 16 is tightened and fixed, the positioning post 15 is inserted into the positioning groove 14 at the top of the nut 16 by sliding the sliding rod 6, which can limit the nut 16 and prevent the nut 16 from loosening due to vibration during equipment operation.

[0023] In this embodiment, during the operation of the fountain aeration equipment, the rotation of the stirring blades will generate a certain amount of vibration. If the nut 16 loosens, the positioning pin 12 may fall off, causing the position of the stirring blades to change, affecting the aeration effect and even causing equipment failure. The cooperation between the positioning post 15 and the positioning groove 14 can effectively limit the rotation of the nut 16, ensuring that the nut 16 always remains in a tight state, thereby ensuring that the positioning pin 12 firmly fixes the square rod 9. At the same time, the sliding rod 6 and the abutment ring 8 also have a certain buffering effect. When the equipment is subjected to external impact, the abutment ring 8 can absorb part of the impact force through the sliding of the sliding rod 6 in the fixing ring 5, reducing the impact of vibration on the fixing components and extending the service life of the equipment.

[0024] The usage method of this embodiment is as follows: The drive motor 1 is installed in the area that needs aeration through the motor mounting bracket. The position of the square rod 9 is slidably adjusted to adjust the height of the inverted umbrella-shaped stirring blade 4. After adjusting the universal joint, the positioning pin 12 is passed through the through hole 11 and enters the positioning hole 10. At the same time, the arc-shaped half fits in the through hole 11. Then, the nut 16 is rotated so that the nut 16 is threadedly connected to the outside of the arc plate 13. At the same time, the inner wall of the nut 16 abuts against the arc plate 13, so that the positioning pin 12 is firmly inserted into the square rod 9. Finally, slide the adjusting contact ring 8 to allow the positioning column 15 to be inserted into the positioning groove 14, thus limiting the position of the nut 16. Then, start the motor to drive the inverted umbrella-shaped stirring blade 4 to rotate. The rotating inverted umbrella-shaped stirring blade 4 stirs the water flow, thereby achieving aeration of the water flow.
