<p>A floating water purification free-running apparatus includes a floating structure, a water purification section, second pumps, a drain outlet, a free-running section, a water quality sensor, a solar cell, an inverter, a sunshine recorder, and a controller. The floating structure is set afloat in a water area. The water purification section filters water in the water area by first pumps. The second pumps inject air into the water area. The drain outlet communicates with the water purification section to drain treated water. The free-running section moves the floating structure in the water area on the basis of a drain injection pressure from the drain outlet. The water quality sensor detects water quality in the water area. The solar cell receives sunlight to generate power. The inverter converts the power into an AC voltage and applies it to each pump. The sunshine recorder measures a sunshine intensity. The controller operates on the basis of the power generated by the solar cell, and controls the number of pumps to be driven in accordance with at least one of sunshine intensity information from the sunshine recorder and the AC voltage and output frequency of the inverter when making the water purification section perform water purification on the basis of an output from the water quality sensor. <IMAGE></p> |
