[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Example

[0021] A retractable coaxial dual-speed compound aerator, such as Figure 1 to Figure 6As shown, it includes a driving component 1, an inflation component 3, a two-speed transmission component 4, an inverted umbrella impeller component, a telescopic shaft component 7 and a push-flow piece 8. The output end of the driving component 1 is connected to the input end of the two-speed transmission component 4. The top side of the two-speed transmission component 4 is provided with an inflation component 3 for introducing air. The two-speed transmission component 4 is respectively connected to the inverted umbrella impeller component and the telescopic shaft component 7. The push-flow piece 8 is connected to the telescopic shaft component 7. A nozzle for outputting air is provided below the push-flow piece 8 at the end of the telescopic shaft component 7. The inverted umbrella impeller component and the telescopic shaft component 7 are respectively connected through the two-speed transmission component 4, so that the coaxial two-speed function of the inverted umbrella impeller component and the telescopic shaft component 7 is realized. The first aeration is realized under the action of the push-flow piece 8, and the secondary aeration of the water body is completed through the inverted umbrella impeller component, thereby improving the effect of the aerator. The telescopic shaft component 7 enables the entire device to adjust the working height according to the depth of the installation position, so as to be suitable for more aeration occasions.

[0022] The drive component 1 is a three-phase asynchronous motor, which is connected to the two-speed transmission component 4 through a coupling 2 to ensure a stable connection between the drive component 1 and the two-speed transmission component 4 and achieve a better transmission effect. The three-phase asynchronous motor has low vibration, low noise, relatively low failure rate, and less energy loss during operation.

[0023] The dual-speed transmission assembly 4 includes a transmission box, an input shaft 41, an intermediate shaft 42 and an output shaft 46. The input shaft 41, the intermediate shaft 42 and the output shaft 46 are installed inside the transmission box. The input shaft 41 and the intermediate shaft 42 are connected by a first gear assembly, and the intermediate shaft 42 and the output shaft 46 are connected by a second gear assembly, which is used to drive the telescopic shaft assembly 7 to rotate at a set second speed. The input shaft 41 is fixedly connected to the driving assembly 1 through a coupling 2, and the output shaft 46 passes through the inverted umbrella impeller assembly and connects the telescopic shaft assembly 7. The intermediate shaft 42 is connected to the inverted umbrella impeller assembly through a third gear assembly, which is used to drive the inverted umbrella impeller assembly to rotate at a set first speed, thereby realizing coaxial dual-speed rotation of the inverted umbrella impeller assembly and the telescopic shaft assembly 7, so that the aeration effect is stronger.

[0024] The first gear assembly includes a first gear 44 mounted on the input shaft 41 and a third gear 48 mounted on the intermediate shaft 42, the second gear assembly includes a second gear 43 mounted on the upper end of the intermediate shaft 42 and a fifth gear 47 on the upper end of the output shaft 46, and the third gear assembly includes a fourth gear 45 mounted on the lower end of the intermediate shaft 42 and a sixth gear 49 on the lower end of the output shaft 46.

[0025] The input shaft 41 and the intermediate shaft 42 transmit power through the first gear 44 and the third gear 48, the intermediate shaft 42 and the output shaft 46 transmit power to the output shaft 46 through the transmission composed of the second gear 43 and the fifth gear 47, and the intermediate shaft 42 and the inverted umbrella impeller hollow shaft 5 transmit power to the inverted umbrella impeller hollow shaft 5 through the fourth gear 45 and the sixth gear 49.

[0026] The telescopic shaft assembly 7 includes a first telescopic shaft 61 and a second telescopic shaft 62. The gas output by the inflation assembly 3 first enters the output shaft 46, and then passes through the first telescopic shaft 61 and the second telescopic shaft 62 in turn through the nozzle into the deep water body. The gas contacts the deep water body to form bubbles. When the bubbles are pushed by buoyancy and rise to the working area of ​​the plug-flow piece 8, the plug-flow piece 8 breaks the bubbles to form a gas-water mixture, completing the first aeration.

[0027] The inverted umbrella impeller assembly comprises an inverted umbrella impeller hollow shaft 5 and an inverted umbrella impeller body 6. The inverted umbrella impeller body 6 is connected to the inverted umbrella impeller hollow shaft 5, and the intermediate shaft 42 is connected to the inverted umbrella impeller hollow shaft 5. When the air-water mixture rises to the working area of ​​the inverted umbrella impeller body 6, under the strong throwing and pushing action of the inverted umbrella impeller body 6, a part of it is thrown out from the edge of the inverted umbrella impeller body 6 to form a water curtain, and then a large amount of air is wrapped in, and a part of it is sucked into the air in the negative pressure area formed by the flow of water at the bottom of the inverted umbrella impeller body 6 and the back of the inverted umbrella impeller body 6, so that the oxygen in the air dissolves into the water, and the two parts form a new air-water mixture together in the shallow water body to complete the second aeration.

[0028] The telescopic shaft assembly 7 includes a first telescopic shaft 61 and a second telescopic shaft 62 . The first telescopic shaft 61 and the second telescopic shaft 62 are connected via guide rails and screws. The connection between the guide rails and the screws ensures that the first telescopic shaft 61 and the second telescopic shaft 62 can achieve transmission. Example

[0029] Based on the first embodiment, a telescopic coaxial dual-speed compound aerator is provided: The inflation component 3 includes an air pump 31, a pipeline, a nozzle and an inflation float 32. One end of the pipeline is connected to the air pump 31 through a rotating joint, and the other end of the pipeline is connected to the nozzle. A sealing ring is provided at the pipeline connection, and a one-way valve is provided on the nozzle.

[0030] The output shaft 46, the first telescopic shaft 61 and the second telescopic shaft 62 are hollow shafts. The gas source input gas of the inflation component 3 enters the pipeline and is then input into the hollow output shaft 46, the first telescopic shaft 61 and the second telescopic shaft 62 through the nozzle to reach the nozzle below the push flow piece 8 at the end of the telescopic shaft assembly 7 and is ejected from the nozzle.

[0031] Different from the first embodiment, the gas can be transported during continuous rotation through the rotary joint connection, a sealing ring is provided on the pipeline to prevent leakage from affecting the operation of the device, and a one-way valve is used to prevent the gas from flowing in reverse, thereby directly improving the inflation efficiency of the aerator. Example

[0032] Based on the first embodiment, a telescopic coaxial dual-speed compound aerator is provided: The inflatable floats 32 of the inflatable assembly use a hollow pipe, and the air pump 31 is connected to the three inflatable floats 32 using a five-way pipe.

[0033] Part of the gas provided by the air pump 31 enters the shallow water body through the hollow pipe and the inflatable float 32. The shallow water body is more fully mixed with oxygen through the three inflatable floats 32, thereby directly improving the inflation efficiency of the aerator.

[0034] Working principle: First, air is introduced through the inflation component 3 and introduced into the nozzle along the telescopic shaft component 7. The air contacts the water to form bubbles, which are pushed up to the working area of ​​the push flow piece 8 by buoyancy. The push flow piece 8 breaks the bubbles to form the first aeration. The air-water mixture then rises to the inverted umbrella impeller component, and secondary aeration is formed under the action of the inverted umbrella impeller component.
