Abstract:
To provide a water cleaning apparatus using a small boat, which can clean polluted water in rivers or the like and allows automated navigation and wireless control.
In a first water cleaning apparatus A1, a Roots blower 3 is operated to supply air sucked from outside to an air diffusion pipe unit 45 so that a large amount of fine bubbles are released into the water. In a second water cleaning apparatus A2, a Roots pump 73 is operated to cause the water mixed with air introduced from an air introduction port 116 to collide with a collision member 123 so that a large amount of bubbles are generated, and the water containing bubbles finely divided by compressive action by the Roots pump 73 is discharged from a discharge pipe 129 on the stern side or a discharge pipe 132 on the bow side into the water to clean the water in rivers or the like and generate a propulsive force for advancing and retreating the small boat 150.
