Is hung at the lower center of the via a connecting portion 15.

The drive source 16 which serves as a power source for supplying electric power to the water purification mechanism 14 has a structure for taking in natural energy, is made of, for example, a solar cell array, and is mounted on the base 12 of the floating body 11. .

The connecting portion 15 is constituted by a vertical rod or a section steel for suspending the water purification mechanism 14.

In the water purification apparatus of this embodiment having the above structure, the water purification mechanism 14 is connected to the floating body 11 by the connecting portion 15.
By sticking to the surface, it floats near the water surface A, and the floating body 1
Since the drive source 16 composed of a solar cell array is attached to the upper part of 1, the electric power required for operating the water purification mechanism 14 is
It can be semi-permanently self-sufficient without producing environmentally harmful emissions.

Even when waves are generated on the water surface A under the influence of strong winds, the water purification mechanism 14 is fixed to the floating body 11 to which the drive source 16 composed of the solar cell array is attached via the connecting portion 15. Since the floating body 11 for supporting the drive source 16 and the floating body 11 for supporting the water purification mechanism 14 are common, there is no inconvenience such as the movement of them in opposite directions as in the conventional case.

As described above, according to the water purification apparatus of this embodiment, the water purification mechanism 14 is fixed to the floating body 11 composed of the plurality of floats 13 and the base body 12 via the connecting portion 15, and Since the driving source 16 such as a solar cell array as an energy source is mounted on the floating body 11, even if a wave is generated on the water surface due to the influence of a strong wind, the floating body 11 has opposite directions.
