Through the design, the floating base body 62 is applied to aeration in a pond, buoyancy is provided for the whole device, the position of the floating base body 62 is stabilized through the balancing weights 63 which are arranged around the floating base body 62, meanwhile, the possibility that the floating base body 62 is overturned by waves is prevented or reduced, meanwhile, the assembling rod 64 which is vertically arranged at the bottom side of the floating base body 62 is connected with the rope body 61 and the connecting frame 54, the control of the depth of the base pipe 1 through the rope body 61 of the control rope body 61 can be realized, and the aeration treatment with the designated depth can be realized; in the aeration process, the water body discharged through the water outlet pipe 12 can form certain flow for the water body with the designated depth of the pond, and the flow speed of the water body in the pond can be improved; in addition, when the metal mesh sheet 55 of the device is positioned at the aeration position, the floating speed of bubbles generated by aeration can be reduced, and the efficient oxygenation of water in the pond can be realized; in addition, the micro-nano bubbles generated by the device burst in the floating process to generate free radical hydroxyl, so that dissolved oxygen of the water body can be increased, meanwhile, part of organic pollutants in the water body can be degraded, and the water body quality in the pond can be improved by realizing the purification of the excretion of the culture in the pond or other pollutants.

While the foregoing embodiments have been described in detail in connection with the embodiments of the utility model, it should be understood that the foregoing embodiments are merely illustrative of the utility model and are not intended to limit the utility model, and any modifications, additions, substitutions and the like made within the principles of the utility model are intended to be included within the scope of the utility model.
