PURPOSE:To remove foreign materials very easily and in a short period of time and collect as well as accumulate the solar energy efficiently by a method wherein a cleaning water intake section, a cleaning water discharging section and a filter, which are movable arbitrarily into depthwise direction and horizontal direction in the solar pond. CONSTITUTION:In the solar pond 4, absorbing and accumulating the solar energy, the water intake section 5 and the water discharging section 13, which are provided in the solar pond and movable arbitrarily in depthwise direction and horizontal direction, as well as the filter, provided in a path from the water intake section to the water discharging section, are provided to catch the foreign materials in said solar pond. The cleaning water intake section 5 is the device for sucking the foreign materials, such as floating leaves, dusts, seaweeds, and microbes, by sucking salt water in the vicinity in the same level. The foreign materials arrive at the strainer 11 through the pipeline 6, flexible tube 10 and the pipeline 6 together with the water. The strainer 11 removes above-described foreign materials by the filter accommodated therein. |
