detailed description

As shown in Figures 1 and 2, an aerator, the motor 2 is fixedly mounted on a radial or disc-shaped support 3, and a plurality of driven gears 5 are arranged on the edge of the support 3, and there are bends on the edge of the support 3. The "C" shaped portion of the shaft constitutes the rotating shaft seat 6, the rotating shaft 4 is rotatable and passes through the rotating shaft seat 6 substantially vertically, the driven gear 5 is fixedly installed on the rotating shaft 4, and the driven gear 5 is connected with the impeller 7 through the rotating shaft 4, specifically The impeller 7 is fixedly installed on the lower end of the rotating shaft 4; a storage battery 1 is also provided, and the storage battery 1 is connected with the motor 2. The accumulator 1 provided makes the whole device not subject to the restriction of power lines, which facilitates the realization of surface cruising.

The motor shaft 10 of the motor 2 is connected to the driving gear 8, and the driving gear 8 is meshed with the driven gear 5; the driving gear 8 is driven to rotate by the motor 2, thereby driving a plurality of driven gears 5 to rotate, and then driving a plurality of impellers 7 to rotate, The rotation of the impeller 7 causes the water to be raised, fully contact with the water, and form a negative pressure zone at the position of the shaft, so that the air and water are further fully mixed. Further preferably, both the driving gear 8 and the driven gear 5 are made of engineering plastics.

As shown in FIG. 2 , a buoy 11 is provided on the bracket 3 or on the driving gear 8 . With this structure, the device is floated on the best oxygen-increasing position on the water surface. What is schematically shown in FIG. 2 is the position where the buoy 11 is installed on the driving gear 8 . The structure in which the buoy is installed on the support 3 is not shown. Preferably, a plurality of buoys 11 are installed on the edge of the bracket 3 . Further preferably, the buoy 11 and the support 3 are connected in a way that can be adjusted up and down, for example, slot-shaped holes are provided on the vertical edge of the bracket, and the up-down adjustment is realized by using the slot-shaped holes.

Preferably, as shown in FIG. 2 , auxiliary vanes 12 are also provided on the driving gear 8 . With this structure, the resistance torque is generated by the rotation of the auxiliary blade 12 so that the bracket 3 itself hardly rotates. In this state, there is no revolution between the impeller 7 and the motor shaft 10 , only the autorotation of the impeller 7 .

Further preferably, the auxiliary vanes 12 are located on the bottom end surface of the driving gear 8 . This structure facilitates installation.

The difference between the torque generated when the auxiliary blades 12 rotate and the torque generated by the multiple impellers 7 rotating around the motor shaft 10 is within 20%. With this structure, the bracket 3 is kept almost non-rotating.

An air inlet pipe 9 is also provided. The opening of the air inlet pipe 9 is higher than the upper end surface of the bracket 3, and the outlet is located near the auxiliary blade 12, preferably near the shaft. The provided air intake pipe 9 can utilize the negative pressure generated when the auxiliary blades 12 rotate to introduce air into the water, thereby achieving sufficient mixing.
